00:00:06,557 --> 00:00:09,040 that when we shoot enemies our score goes up, up, up. 4 4 00:00:09,040 --> 00:00:14,250 And then when we die we have that same score presented on our game over screen. 5 5 00:00:14,250 --> 00:00:17,050 So what I wanna do is start off with a challenge in this video and 6 6 00:00:17,050 --> 00:00:19,130 the challenge is to add score to your game. 7 7 00:00:19,130 --> 00:00:20,770 Killing enemies increases your score. 8 8 00:00:20,770 --> 00:00:24,040 And I wanna give you a reminder of what's required by showing you what 9 9 00:00:24,040 --> 00:00:25,780 I've just gone and implemented. 10 10 00:00:25,780 --> 00:00:29,530 I've come back in the future, back to the future, back from the past. 11 11 00:00:29,530 --> 00:00:32,789 Anyway, I've just recorded it, and I'm recording the start of the video now. 12 12 00:00:32,789 --> 00:00:34,026 I wanna show you what I've done so 13 13 00:00:34,026 --> 00:00:36,202 that if you want some reminders you know what's going on. 14 14 00:00:36,202 --> 00:00:40,568 I've created a game session game object out of the game session script of that. 15 15 00:00:40,568 --> 00:00:44,941 Within the game session script I'm doing a couple of things, 16 16 00:00:44,941 --> 00:00:49,986 I'm creating a singleton pattern, I'm creating a score variable and 17 17 00:00:49,986 --> 00:00:55,217 then three public methods to GetScore, to AddToScore and to ResetGame. 18 18 00:00:55,217 --> 00:00:56,618 I'm showing you these very quickly, 19 19 00:00:56,618 --> 00:00:58,734 I'm going to go through them in super detail in a moment. 20 20 00:00:58,734 --> 00:01:02,815 But I'm showing you if you wanna go and do this challenge yourself, 21 21 00:01:02,815 --> 00:01:08,055 I'm also creating a score display which is getting the text component that our score. 22 22 00:01:08,055 --> 00:01:13,319 So main canvas that our score text is on as well as the game object of game 23 23 00:01:13,319 --> 00:01:18,815 session To be out of called the public method of getting the score. 24 24 00:01:18,815 --> 00:01:25,112 And then we are updating on every frame, the score by using the ToString method. 25 25 00:01:25,112 --> 00:01:30,211 Finally, when we kill an enemy, we need to have a score value and when we die, 26 26 00:01:30,211 --> 00:01:35,481 when the enemy dies, we are calling the AddToScore and passing in scoreValue. 27 27 00:01:35,481 --> 00:01:38,166 So that's just a really quick rundown, if you wanted to go and 28 28 00:01:38,166 --> 00:01:41,215 do this as a challenge yourself and have some reminders and pointers, 29 29 00:01:41,215 --> 00:01:42,262 that is the challenge. 30 30 00:01:42,262 --> 00:01:45,374 So jump in, take on that challenge now, give it your best shot. 31 31 00:01:45,374 --> 00:01:48,728 And I'll see you here when you're done, we'll go through it together in detail. 32 32 00:01:51,432 --> 00:01:53,150 Okay, let's get shifty. 33 33 00:01:53,150 --> 00:01:56,160 First thing I'm gonna do is free up a little bit of space in my hierarchy, 34 34 00:01:56,160 --> 00:01:57,760 right click Create Empty. 35 35 00:01:57,760 --> 00:02:02,380 I'm gonna call this Game Elements, and I'm just gonna shove anything in here that I 36 36 00:02:02,380 --> 00:02:04,970 don't need have a look at reset that transform. 37 37 00:02:04,970 --> 00:02:08,980 So I'm gonna grab the background star field, star field, shredder shredder. 38 38 00:02:08,980 --> 00:02:12,020 Drop those into the game elements, the path and the other path, 39 39 00:02:12,020 --> 00:02:13,720 drop those in there. 40 40 00:02:13,720 --> 00:02:17,040 That's pretty good, and then just close up game elements, 41 41 00:02:17,040 --> 00:02:20,950 drag it up to the very top so it's tucked neatly out of the way. 42 42 00:02:20,950 --> 00:02:25,910 Excellent, next I'm gonna right click and Create Empty, create a game session. 43 43 00:02:27,410 --> 00:02:30,090 Game session, game object. 44 44 00:02:30,090 --> 00:02:33,740 Within the Game Session game object, we're going to create ourselves a script. 45 45 00:02:33,740 --> 00:02:38,469 Which I will click on my script folder, right click, click C# script. 46 46 00:02:38,469 --> 00:02:42,770 I'm gonna call this, you guessed it, GameSession. 47 47 00:02:42,770 --> 00:02:45,616 Okay, and then drag the GameSession script onto, 48 48 00:02:45,616 --> 00:02:49,454 when it finishes figuring out that it's alive, okay you are alive, 49 49 00:02:49,454 --> 00:02:53,445 great, the game session, script under the Game Session game object. 50 50 00:02:53,445 --> 00:02:56,264 And then while we're here for due diligence, 51 51 00:02:56,264 --> 00:03:01,263 drag the Game Session game object into our prefers folder so it is now prefer core. 52 52 00:03:01,263 --> 00:03:04,415 You might have noticed that my assets folder here has changed a little bit. 53 53 00:03:04,415 --> 00:03:07,302 I've just gone and drag my slider from folders down in to lists, 54 54 00:03:07,302 --> 00:03:10,970 because that's making it a little bit neater and tidier to see what's going on. 55 55 00:03:10,970 --> 00:03:12,950 Okay, we're going to need one more script in this video. 56 56 00:03:12,950 --> 00:03:15,987 So script folder, right click, create c sharp. 57 57 00:03:15,987 --> 00:03:20,845 I'm gonna call this particular script ScoreDisplay so 58 58 00:03:20,845 --> 00:03:23,455 that we can be displaying our score. 59 59 00:03:23,455 --> 00:03:24,765 So this is our script building block. 60 60 00:03:24,765 --> 00:03:27,480 So next stop I'm gonna add my score UI element to the screen. 61 61 00:03:27,480 --> 00:03:32,086 So find the game canvas, right click create a UI text. 62 62 00:03:32,086 --> 00:03:35,480 Now, we could do TextMeshPro-Text we could do text we tend to do a lot 63 63 00:03:35,480 --> 00:03:36,359 of TextMeshPro, 64 64 00:03:36,359 --> 00:03:40,070 cuz I think it gives us a little bit more control looks a little bit crisper. 65 65 00:03:40,070 --> 00:03:44,405 But in this video I'm gonna be doing score using just tick so that we've done the way 66 66 00:03:44,405 --> 00:03:47,705 so you can see it is wanting to do text you know how to do text. 67 67 00:03:47,705 --> 00:03:49,265 So were covering a few different bases, 68 68 00:03:49,265 --> 00:03:52,840 but in general you'd probably just do one or the other. 69 69 00:03:52,840 --> 00:03:56,515 Okay our text we'll rename to be score text and 70 70 00:03:56,515 --> 00:04:00,860 then let's see click, if you click on your game canvas, 71 71 00:04:00,860 --> 00:04:03,370 that'll zoom you can see score text on your screen. 72 72 00:04:03,370 --> 00:04:04,950 So right size is tiny at the moment. 73 73 00:04:04,950 --> 00:04:08,618 So let's click on Score Text, change our font to 100. 74 74 00:04:08,618 --> 00:04:13,800 Change the color to be, for now, white until I have a better idea. 75 75 00:04:13,800 --> 00:04:19,843 Change from the New Text in the text field to 000000, that's kind of six 0s I think. 76 76 00:04:19,843 --> 00:04:22,841 And then w, whoops, not a w there! 77 77 00:04:22,841 --> 00:04:24,186 Click on Score Text. 78 78 00:04:24,186 --> 00:04:29,569 W tall move it roughly up to the top right of my screen. 79 79 00:04:29,569 --> 00:04:31,346 I need to zoom in a little bit. 80 80 00:04:31,346 --> 00:04:33,700 I'm gonna click on my T-tool. 81 81 00:04:33,700 --> 00:04:36,045 And make it bigger so we can actually see it. 82 82 00:04:36,045 --> 00:04:39,529 There it goes, it pops into existence, make it nice and large. 83 83 00:04:39,529 --> 00:04:45,390 Right click or right align and I like to center line things. 84 84 00:04:45,390 --> 00:04:49,210 Now, change the font so font, select that, whatever you've selected for your game, 85 85 00:04:49,210 --> 00:04:52,380 I've got batman FA just here, looks pretty crisp over there, 86 86 00:04:52,380 --> 00:04:55,750 I like it gonna move it up just a little bit more and very important, 87 87 00:04:55,750 --> 00:04:58,510 click on the anchor and then right click on the anchor. 88 88 00:04:58,510 --> 00:05:03,138 So no matter whatever screen resolution and aspect ratio we have our score, 89 89 00:05:03,138 --> 00:05:05,975 we anchored up to the top right of your screen. 90 90 00:05:05,975 --> 00:05:08,451 Okay, now we have score, it called Score Text, perfect, 91 91 00:05:08,451 --> 00:05:09,745 that all looking pretty good. 92 92 00:05:09,745 --> 00:05:15,110 Our script we just made, which was the ScoreDisplay. 93 93 00:05:15,110 --> 00:05:17,540 We're gonna drag that over onto score. 94 94 00:05:18,705 --> 00:05:21,510 Excellent, or you can add component and search for it, either of those ways. 95 95 00:05:21,510 --> 00:05:23,940 Now we have our score display on our score. 96 96 00:05:23,940 --> 00:05:26,330 Our last thing we're gonna do is change the color just to make it a little bit 97 97 00:05:26,330 --> 00:05:34,240 more of a bright blue spacey, fluorescent kind of, there we go, wonderful. 98 98 00:05:34,240 --> 00:05:35,490 Okay, so I've got score, 99 99 00:05:35,490 --> 00:05:39,120 I've got my scripts, we're ready to jump into the scripts. 100 100 00:05:39,120 --> 00:05:44,330 Find our game session, double click on that, open it up, jump into Visual Studio. 101 101 00:05:44,330 --> 00:05:48,160 First thing I need to do is create a notion of score. 102 102 00:05:48,160 --> 00:05:55,628 So score a little s, score initialize that 0; so you have your score. 103 103 00:05:55,628 --> 00:06:00,556 Next, I'm gonna implement a singleton, so that our game session there is only one of 104 104 00:06:00,556 --> 00:06:05,218 them and we can reuse our score in our game overscreen because it's a singleton. 105 105 00:06:05,218 --> 00:06:10,133 So I'm gonna create Awake, so it's the very very first thing it does 106 106 00:06:10,133 --> 00:06:14,371 when it wakes up it will SetUpSingleton(); as a method, 107 107 00:06:14,371 --> 00:06:19,969 right click on SetUpSingleton quick actions and refactors generate method or 108 108 00:06:19,969 --> 00:06:23,732 you can just type it out yourself if you like typing. 109 109 00:06:23,732 --> 00:06:26,486 And then, I'm gonna delete the default line that's in there. 110 110 00:06:26,486 --> 00:06:27,252 What do we need to do? 111 111 00:06:27,252 --> 00:06:32,382 Well, we need the integer, which is how many game sessions we have already. 112 112 00:06:32,382 --> 00:06:39,370 So int numberGameSessions and what does that equal? 113 113 00:06:39,370 --> 00:06:41,510 Well, we need to find how many sessions there are. 114 114 00:06:41,510 --> 00:06:47,065 So I say FindObjectsOfType and again, I'm gonna do the s a few different times. 115 115 00:06:47,065 --> 00:06:49,170 So you're like, there's an s in there, don't forget that. 116 116 00:06:49,170 --> 00:06:51,897 That's the most common thing, if this line of code's not going well, 117 117 00:06:51,897 --> 00:06:53,223 it's cuz we've forgotten the s. 118 118 00:06:53,223 --> 00:06:55,067 It's game objects of type. 119 119 00:06:55,067 --> 00:06:59,247 We're looking for GameSession(). 120 120 00:06:59,247 --> 00:07:00,895 How do we know how long it is? 121 121 00:07:00,895 --> 00:07:03,879 Well, we type in length, okay? 122 122 00:07:06,271 --> 00:07:10,058 Now we need to do our if, so 123 123 00:07:10,058 --> 00:07:15,746 if (numberGameSessions > 1) curly 124 124 00:07:15,746 --> 00:07:22,470 brace space we will Destroy(gameObject); 125 125 00:07:22,470 --> 00:07:29,211 else DontDestroyOnLoad(gameObject);. 126 126 00:07:29,211 --> 00:07:32,780 Save that looking good except we don't have our colored braces. 127 127 00:07:32,780 --> 00:07:34,430 Being a little bit hasty here, 128 128 00:07:34,430 --> 00:07:37,955 curly braces that wrap around our code block of DontdestroyOnLoad. 129 129 00:07:37,955 --> 00:07:39,070 Okay, that's looking pretty good, 130 130 00:07:39,070 --> 00:07:41,320 we've got our single term we're running it on Awake. 131 131 00:07:41,320 --> 00:07:42,640 We're calling it on Awake. 132 132 00:07:42,640 --> 00:07:46,490 Next up we want to add three public 133 133 00:07:46,490 --> 00:07:49,770 methods that we can call from other scripts or other areas and 134 134 00:07:49,770 --> 00:07:54,390 we get rid of start, don't need that, also don't need update so clear those out. 135 135 00:07:54,390 --> 00:07:57,500 Public method number one is gonna be for getting the score, so 136 136 00:07:57,500 --> 00:08:00,470 public int GetScore(). 137 137 00:08:00,470 --> 00:08:02,460 Why is it an int I ask you? 138 138 00:08:02,460 --> 00:08:07,680 It's an int because we have to return a value, and that value is score, and 139 139 00:08:07,680 --> 00:08:12,630 the score is an int, so whenever we call that it will return score which is an int. 140 140 00:08:12,630 --> 00:08:16,723 Next public method, public, this will be void, there's no return type. 141 141 00:08:16,723 --> 00:08:22,168 We'll call this AddToScore, this is where another class or another moment in 142 142 00:08:22,168 --> 00:08:27,375 our game can say, hey, game session, please add something to the score. 143 143 00:08:27,375 --> 00:08:28,320 What's the something? 144 144 00:08:28,320 --> 00:08:30,930 Well we need to know how many points to add to the score. 145 145 00:08:30,930 --> 00:08:33,656 This is where we'll have a requirement in here, we'll have a parameter. 146 146 00:08:33,656 --> 00:08:38,094 Which we will make it an int, and we'll look for a score value. 147 147 00:08:38,094 --> 00:08:39,999 So if you want to call AddToScore, 148 148 00:08:39,999 --> 00:08:42,903 you need to tell me the score value that I'm adding. 149 149 00:08:42,903 --> 00:08:47,626 And then within our method, within our code block here we take out current score 150 150 00:08:47,626 --> 00:08:49,895 +=, what's it gonna plus equals? 151 151 00:08:49,895 --> 00:08:54,484 It's gonna plus equal ScoreValue, so it is taking our current score and 152 152 00:08:54,484 --> 00:08:55,687 then adding to it, 153 153 00:08:55,687 --> 00:09:00,903 where the scoreValue is that was passed to us by the thing that called add to score. 154 154 00:09:00,903 --> 00:09:02,953 We will make one more Public Method while we are here. 155 155 00:09:02,953 --> 00:09:09,779 Public V=void ResetGame() and then {. 156 156 00:09:09,779 --> 00:09:10,624 What are we doing here? 157 157 00:09:10,624 --> 00:09:14,455 Well this is just simply destroying this game session objects. 158 158 00:09:14,455 --> 00:09:19,168 So, Destroy(gameObject);. 159 159 00:09:19,168 --> 00:09:22,577 Okay, so there's game session all created, looking pretty good, 160 160 00:09:22,577 --> 00:09:26,460 no functionality we can see in the game just yet but that is pretty tight. 161 161 00:09:26,460 --> 00:09:32,060 Next up we need to find our score text and specifically our score display. 162 162 00:09:32,060 --> 00:09:34,143 So we've already opened that I believe, 163 163 00:09:34,143 --> 00:09:36,413 score display here we go just nice and empty. 164 164 00:09:36,413 --> 00:09:41,343 We're working in UI so we want to start off by 165 165 00:09:41,343 --> 00:09:46,422 adding a namespace using UnityEngine.UI. 166 166 00:09:46,422 --> 00:09:50,850 And remember if you are using TextMeshPro instead of just the text component, 167 167 00:09:50,850 --> 00:09:54,002 you'll need to add the TextMesh Pro namespace in here or 168 168 00:09:54,002 --> 00:09:57,450 else things won't go as you're expecting them. 169 169 00:09:57,450 --> 00:09:59,430 Now, what do we need to do in our score display? 170 170 00:09:59,430 --> 00:10:04,110 First of all, we need to get the component where we want to display the score. 171 171 00:10:04,110 --> 00:10:05,330 So if you have a look on your text, 172 172 00:10:05,330 --> 00:10:08,800 score text, we have the text component just in here. 173 173 00:10:08,800 --> 00:10:12,240 So we need to get this, and then within that we have the text field. 174 174 00:10:12,240 --> 00:10:15,174 So there's a lot of texts, I know we've dealt with this in previous sections, 175 175 00:10:15,174 --> 00:10:20,430 text.text.text it feels like there's 70 text, but this is the text component and 176 176 00:10:20,430 --> 00:10:24,130 this is the text value of the text field that is within that. 177 177 00:10:24,130 --> 00:10:29,270 So to get access to that text component we start off by creating ourselves a variable 178 178 00:10:29,270 --> 00:10:34,740 to store that in which will be a text type variable called scoreText;. 179 179 00:10:34,740 --> 00:10:36,051 And in the scoreText;. 180 180 00:10:36,051 --> 00:10:39,955 And then when we start our game, we need to give scoreText a value, 181 181 00:10:39,955 --> 00:10:42,064 which is going to be the component. 182 182 00:10:42,064 --> 00:10:49,980 So GetComponent<Text>();. 183 183 00:10:49,980 --> 00:10:54,030 Okay, so get the component text stored as this scoreText variable, 184 184 00:10:54,030 --> 00:10:57,720 which we've declared as a type of text, excellent. 185 185 00:10:57,720 --> 00:11:02,610 Next, we need to do similar for finding where the score is coming from and 186 186 00:11:02,610 --> 00:11:05,580 we know the score is going to be stored in game session. 187 187 00:11:05,580 --> 00:11:09,970 So let's create a type GameSession. 188 188 00:11:09,970 --> 00:11:14,250 We'll call this gameSession with a small g, semi-colon. 189 189 00:11:14,250 --> 00:11:19,700 Now also on the start when our score display comes into existence, 190 190 00:11:19,700 --> 00:11:23,040 we need to go and find the game session. 191 191 00:11:23,040 --> 00:11:27,945 So we need to define gameSession that we've just created as a variable as, well, 192 192 00:11:27,945 --> 00:11:30,803 we need to define it as this gameSession class. 193 193 00:11:30,803 --> 00:11:34,931 So that's a type, we need to 194 194 00:11:34,931 --> 00:11:41,645 FindObjectOfType <GameSession>();. 195 195 00:11:41,645 --> 00:11:44,427 So we've gone and got ourselves a reference to the component, 196 196 00:11:44,427 --> 00:11:47,745 and we've gone and got ourselves a reference to the GameSession. 197 197 00:11:47,745 --> 00:11:50,820 Now on update, all we need to do is to say 198 198 00:11:50,820 --> 00:11:58,650 scoreText.text=gameSession. 199 199 00:11:58,650 --> 00:12:04,858 What's our method that we've created in game session, we're looking for 200 200 00:12:04,858 --> 00:12:11,083 get score because we need to know the score so gamesession.GetScore(). 201 201 00:12:11,083 --> 00:12:15,804 And then we need to be converting this into a string because we 202 202 00:12:15,804 --> 00:12:18,221 have an integer at the moment. 203 203 00:12:18,221 --> 00:12:22,496 The score itself is a integer and our text field is a string. 204 204 00:12:22,496 --> 00:12:29,850 So to convert out integer into a string we say ToString();. 205 205 00:12:29,850 --> 00:12:32,202 Sets are looking pretty good, let's jump over to Unity, 206 206 00:12:32,202 --> 00:12:34,554 see if we've got any sort of different behavior going on. 207 207 00:12:34,554 --> 00:12:38,910 We should have, yes, it goes from allow placeholder zeros to just one zero. 208 208 00:12:38,910 --> 00:12:44,028 And then no score going up, but so far, so good. 209 209 00:12:44,028 --> 00:12:46,380 Okay, so how do we make our score go up? 210 210 00:12:46,380 --> 00:12:49,070 Where is it happening that our score should go up? 211 211 00:12:49,070 --> 00:12:51,970 Well, at the moment, we've only got enemies in our game, that's, 212 212 00:12:51,970 --> 00:12:53,080 we shoot them, we get points. 213 213 00:12:53,080 --> 00:12:57,920 So let's go on find out enemy script, without enemy script we need to start off 214 214 00:12:57,920 --> 00:13:00,975 by creating a concept that the enemies give us points. 215 215 00:13:00,975 --> 00:13:04,490 And I've been putting this off for awhile but I can't put it off any longer. 216 216 00:13:04,490 --> 00:13:07,885 Let's tidy up our variables so it's tidy in our inspector and 217 217 00:13:07,885 --> 00:13:10,901 tidy in our script cause this is a big old blob of stuff. 218 218 00:13:10,901 --> 00:13:18,541 So I'm gonna create a [Header("")]. 219 219 00:13:18,541 --> 00:13:19,460 What are we gonna say in here. 220 220 00:13:19,460 --> 00:13:22,843 Well, first up we've got enemy stats, this looks like. 221 221 00:13:22,843 --> 00:13:24,285 We've got some enemy stats. 222 222 00:13:24,285 --> 00:13:28,176 I'm gonna go and create a new enemy stat which will be 223 223 00:13:28,176 --> 00:13:33,470 SerializeField of integer type that I will call scoreValue. 224 224 00:13:33,470 --> 00:13:37,290 That'll be the scoreValue of this particular enemy, and 225 225 00:13:37,290 --> 00:13:39,730 that will equal 150;. 226 226 00:13:39,730 --> 00:13:45,130 Cool, next up, let's see, copy my header code and then paste 227 227 00:13:45,130 --> 00:13:50,690 that above the next blob of code this blob of code is all about shooting, I believe. 228 228 00:13:50,690 --> 00:13:54,000 Shooting, we have counter shot projectile, projectile. 229 229 00:13:54,000 --> 00:13:56,590 Okay, after my last projectile, a couple of spaces. 230 230 00:13:56,590 --> 00:13:58,600 Paste in our header again. 231 231 00:13:59,710 --> 00:14:00,500 What are these all about? 232 232 00:14:00,500 --> 00:14:01,790 This is all about sound effects. 233 233 00:14:01,790 --> 00:14:03,560 Sound effects. 234 234 00:14:03,560 --> 00:14:05,510 Okay, so much tardier. 235 235 00:14:05,510 --> 00:14:07,570 I'm much happier with that. 236 236 00:14:07,570 --> 00:14:09,087 Now, we've created score value. 237 237 00:14:09,087 --> 00:14:12,604 Let's go and find where we will make our score increase. 238 238 00:14:12,604 --> 00:14:16,335 I think when the enemy dies, that's a good place to increase the score. 239 239 00:14:16,335 --> 00:14:17,755 So what are we doing here? 240 240 00:14:17,755 --> 00:14:20,803 Let's just go remind ourselves over in game session, 241 241 00:14:20,803 --> 00:14:22,802 we've got our AddToScore method. 242 242 00:14:22,802 --> 00:14:25,904 How do we call add to score method from another script? 243 243 00:14:25,904 --> 00:14:30,277 Well, we say FindObjectOfType, 244 244 00:14:30,277 --> 00:14:35,715 we're looking for the GameSession(). 245 245 00:14:35,715 --> 00:14:41,597 This is what we call our AddToScore();. 246 246 00:14:41,597 --> 00:14:45,820 Semi-colon is not working because, can you guess why not? 247 247 00:14:45,820 --> 00:14:47,965 Because we need to give it a value. 248 248 00:14:47,965 --> 00:14:51,100 A reminder, over here we need the value of scoreValue, 249 249 00:14:51,100 --> 00:14:54,760 you need to tell it how many points you're worth, you can't just let it guess. 250 250 00:14:54,760 --> 00:14:56,860 So in here, it's gonna be nice and simple. 251 251 00:14:56,860 --> 00:15:01,170 We have our scoreValue and we've named it the same, clever us. 252 252 00:15:01,170 --> 00:15:04,650 ScoreValue, so back down into AddToScore. 253 253 00:15:04,650 --> 00:15:06,990 Score value blank. 254 254 00:15:08,230 --> 00:15:09,500 Okay, let's save all that up. 255 255 00:15:09,500 --> 00:15:12,030 I think we have implemented everything. 256 256 00:15:12,030 --> 00:15:12,870 Click on play. 257 257 00:15:12,870 --> 00:15:14,050 What's gonna go on here? 258 258 00:15:14,050 --> 00:15:15,715 We will from zero [INAUDIBLE]. 259 259 00:15:15,715 --> 00:15:17,602 Okay, score's going up 300, 600. 260 260 00:15:17,602 --> 00:15:19,600 Excellent, success. 261 261 00:15:19,600 --> 00:15:23,460 But when we die we get a moment to look at the score but 262 262 00:15:23,460 --> 00:15:27,080 there's no real moment on here where I can look at the score, call my friend over. 263 263 00:15:27,080 --> 00:15:29,480 Hey, look, I beat your score, whatever it might be, 264 264 00:15:29,480 --> 00:15:32,210 so let's have the score display on the screen as well. 265 265 00:15:32,210 --> 00:15:36,600 And we've set ourselves up with our game session is a singleton, so 266 266 00:15:36,600 --> 00:15:37,680 it will continue. 267 267 00:15:37,680 --> 00:15:39,930 It will exist and live into the next screen, 268 268 00:15:39,930 --> 00:15:42,300 which is very important, the next scene. 269 269 00:15:42,300 --> 00:15:45,220 So I've prefabbed that good stuff. 270 270 00:15:45,220 --> 00:15:47,270 The game canvas, here's a little thing. 271 271 00:15:47,270 --> 00:15:50,820 I wasn't planning on doing this, but just spur of the moment, I think I will. 272 272 00:15:50,820 --> 00:15:53,650 See how we currently have our game canvas prefab, and 273 273 00:15:53,650 --> 00:15:55,560 there's only one element here the score text. 274 274 00:15:55,560 --> 00:15:58,900 So I'll click on apply, so now our game canvas and 275 275 00:15:58,900 --> 00:16:03,350 score text have been updated in terms of the prefab. 276 276 00:16:03,350 --> 00:16:09,245 So if we say all this up, jump over into [SOUND] where are we, the scene. 277 277 00:16:09,245 --> 00:16:10,697 Game Over scene. 278 278 00:16:10,697 --> 00:16:16,297 If I find my prefab and drag the Game Canvas 279 279 00:16:16,297 --> 00:16:21,424 into this scene, it adds it in there. 280 280 00:16:21,424 --> 00:16:22,982 We can have multiple canvases, 281 281 00:16:22,982 --> 00:16:25,929 you can have a whole ton of canvases doing different things. 282 282 00:16:25,929 --> 00:16:28,877 That's something that we haven't talked about much because we've 283 283 00:16:28,877 --> 00:16:31,469 been putting everything under the one particular canvas but 284 284 00:16:31,469 --> 00:16:33,565 you could turn our particular canvas on and off. 285 285 00:16:33,565 --> 00:16:35,418 You can move the canvases around. 286 286 00:16:35,418 --> 00:16:40,329 So this game canvas, I'm gonna change the position of it, of the score text. 287 287 00:16:40,329 --> 00:16:46,091 I'm gonna change the score text position to be, let's see in the middle just there. 288 288 00:16:46,091 --> 00:16:47,971 So the score goes form being up in the top right, 289 289 00:16:47,971 --> 00:16:50,803 when it's game over you get the score right in the middle of the screen. 290 290 00:16:50,803 --> 00:16:54,415 Do a couple of things in here, I will just drag it to the right, and 291 291 00:16:54,415 --> 00:16:55,970 drag it to the left so. 292 292 00:16:55,970 --> 00:16:58,110 And then center align so I know it's right in the middle. 293 293 00:16:58,110 --> 00:17:01,640 And then we need to change the anchor point, 294 294 00:17:01,640 --> 00:17:03,640 rather than the anchor point being up in the top right. 295 295 00:17:03,640 --> 00:17:06,490 That's gonna be a little bit messy if our resolution or our pixel, 296 296 00:17:06,490 --> 00:17:08,130 aspect ratio changes. 297 297 00:17:08,130 --> 00:17:11,400 Let's anchor this right into the very middle of our screen. 298 298 00:17:13,080 --> 00:17:15,670 Okay, there might be a little bit of tidy up of anchoring our other 299 299 00:17:15,670 --> 00:17:16,460 elements in the scene. 300 300 00:17:16,460 --> 00:17:17,340 I'm not gonna go through that. 301 301 00:17:17,340 --> 00:17:20,090 You know how to do that now in terms of anchoring things into a particular 302 302 00:17:20,090 --> 00:17:22,260 position if the aspect ratio is changing, 303 303 00:17:22,260 --> 00:17:24,680 but this is all looking pretty cool for now. 304 304 00:17:24,680 --> 00:17:26,770 We're getting an error down the bottom, assertion failed. 305 305 00:17:26,770 --> 00:17:29,210 I think that might have just been cuz I was playing around and 306 306 00:17:29,210 --> 00:17:29,950 moving things around. 307 307 00:17:29,950 --> 00:17:32,020 We'll clear it and we'll see if it comes up again and then we'll go and 308 308 00:17:32,020 --> 00:17:34,220 dive in and see what needs to happen to fix it. 309 309 00:17:34,220 --> 00:17:38,740 But let's go back to start, we'll go back to the very start of our game, 310 310 00:17:38,740 --> 00:17:41,682 very start start, click on START menu. 311 311 00:17:41,682 --> 00:17:46,768 Okay, so click on START, and then sorry, click on Play, and then START. 312 312 00:17:46,768 --> 00:17:48,810 We will [SOUND] start our start. 313 313 00:17:48,810 --> 00:17:51,824 Okay, score is going up, excellent, we crash into someone. 314 314 00:17:51,824 --> 00:17:53,333 [SOUND] 1050. 315 315 00:17:53,333 --> 00:17:54,538 Is 1050 retained? 316 316 00:17:54,538 --> 00:17:55,962 Yes, it is, all the way here. 317 317 00:17:55,962 --> 00:18:00,124 What happens when we play again, goes to zero, and, okay, so 318 318 00:18:00,124 --> 00:18:01,942 our score's not going up. 319 319 00:18:01,942 --> 00:18:02,667 Why is that? 320 320 00:18:02,667 --> 00:18:10,142 I suspect because we are not properly resetting our level loading. 321 321 00:18:10,142 --> 00:18:13,702 So let's have a look at our gamesession in here. 322 322 00:18:13,702 --> 00:18:16,158 We've created ResetGame, which was clever of us, but 323 323 00:18:16,158 --> 00:18:17,943 we're not actually calling it any way. 324 324 00:18:17,943 --> 00:18:20,283 Where would we reset our game? 325 325 00:18:20,283 --> 00:18:22,008 I think that's gonna be in level, isn't it? 326 326 00:18:22,008 --> 00:18:25,144 When the player says load the game, so load the game scene, 327 327 00:18:25,144 --> 00:18:26,857 that's where we need to reset. 328 328 00:18:26,857 --> 00:18:30,122 So once again, how do we find this particular public method? 329 329 00:18:30,122 --> 00:18:34,703 We will say FindObjectOfType and 330 330 00:18:34,703 --> 00:18:38,957 it is type GameSession() and 331 331 00:18:38,957 --> 00:18:44,450 we're calling ResetGame();. 332 332 00:18:44,450 --> 00:18:46,450 Okay, resetting game, so save this. 333 333 00:18:46,450 --> 00:18:48,440 I'll jump back over into Unity, click on play. 334 334 00:18:48,440 --> 00:18:50,410 See what we can do with the full loop now if we can, 335 335 00:18:50,410 --> 00:18:52,380 then we'll declare this success. 336 336 00:18:52,380 --> 00:18:54,190 Click on start, shoot, shoot, shoot. 337 337 00:18:54,190 --> 00:18:57,170 Get some points, shoot, shoot, die. 338 338 00:18:57,170 --> 00:18:59,880 600 should be retained in here, you can put an extra 339 339 00:18:59,880 --> 00:19:04,010 text run here saying you scored or your score is 600, if you like. 340 340 00:19:04,010 --> 00:19:07,892 Back to main menu, click on Start, start at 0, 341 341 00:19:07,892 --> 00:19:11,890 scores goes up and then [SOUND] back into Game Over. 342 342 00:19:11,890 --> 00:19:13,670 One more thing we need to try play again. 343 343 00:19:13,670 --> 00:19:15,060 Yeah, and the score does go up. 344 344 00:19:15,060 --> 00:19:16,290 Okay, just a quick side note here, 345 345 00:19:16,290 --> 00:19:19,280 I had a couple of errors on my screen here, I just went and cleared them, 346 346 00:19:19,280 --> 00:19:22,090 played the game through a couple of time and the errors don't come back again. 347 347 00:19:22,090 --> 00:19:25,100 So I forgot to mention that before I pause the video, 348 348 00:19:25,100 --> 00:19:28,410 but I've cleared out all the errors just in case you're wondering. 349 349 00:19:28,410 --> 00:19:31,860 So great work in this lecture, great work with your progress. 350 350 00:19:31,860 --> 00:19:34,260 Pretty excited to see score in our game. 351 351 00:19:34,260 --> 00:19:36,780 We can implement it in so many more places now. 352 352 00:19:36,780 --> 00:19:38,690 We can have it when you shoot an enemy, 353 353 00:19:38,690 --> 00:19:41,540 the enemy spawns a whole bunch of little coins that you go pick up. 354 354 00:19:41,540 --> 00:19:43,080 Like little pickups for points. 355 355 00:19:43,080 --> 00:19:45,950 It could be that you just have super mega point 356 356 00:19:45,950 --> 00:19:48,030 things floating down your screen that you can pick up. 357 357 00:19:48,030 --> 00:19:51,670 Lots of places you can do it above and beyond I just shoot an enemy and 358 358 00:19:51,670 --> 00:19:52,480 I get points. 359 359 00:19:52,480 --> 00:19:55,844 So great work with this lecture, great work with your progress, and 360 360 00:19:55,844 --> 00:19:57,420 I'll see you in the next video. 36162
