In this video, we're gonna create the two extra states of running and 3

3

climbing to go along with our idling state. 4

4

And I'll introduce you to transitions. 5

5

We'll make some parameters so that we can transition from one state to another 6

6

simply by clicking the checkbox here to show now my character is climbing, and 7

7

now my character is running. 8

8

Let's jump in and get started. 9

9

Okay, let's navigate our way to the sprite sheet for the character. 10

10

We can see it there. 11

11

We've got a bunch of sprites to choose from. 12

12

What we're going to start off with is running, I think. 13

13

So we're gonna scroll down and look for the running. 14

14

I'm just gonna go and open up the sprite sheet itself so 15

15

I can see where that goes from. 16

16

If I look in there, it's this bottom one here that's the run animation. 17

17

So it'd be the very last frame starting from 19 and going until 28. 18

18

So that's gonna be our run. 19

19

Don't worry about doing that. 20

20

Okay, so let's go find 19 in our sprite sheet here, 15, 16, 17, 18, 19. 21

21

As we did before, we're gonna highlight everything all the way down 22

22

to the final one down here, right-click, Create > Animation. 23

23

We'll call this Running, wonderful. 24

24

Now from here, we can, as we did before, 25

25

drag that into our Animator, Animator Controller. 26

26

We have this state of Running that at the moment consists of our running animation 27

27

and not much else. 28

28

While we're here, let's click on Running and make sure we loop that and 29

29

drag Running into the Animations folder. 30

30

So now we have Running and Idle. 31

31

As a piece of consistency, I'm gonna rename Idle to Idling. 32

32

It's not really a word, but 33

33

I wanna have my states very clearly be the thing that you are doing at the moment. 34

34

You're running at the moment, you're climbing at the moment, 35

35

you're idling at the moment. 36

36

So that's super duper clear on that. 37

37

Okay, now we have our Running state. 38

38

We need to make a transition from Idling to Running so 39

39

that we can say what needs to happen for 40

40

the player to stop being in an idling state and start being in a running state. 41

41

To make a transition, right-click on the state, click on Make Transition and 42

42

then you'll have this arrow that you can point elsewhere. 43

43

We'll point over the Running and left-click on there. 44

44

So now I have a state transition leading into Running. 45

45

If you click on the arrow itself or 46

46

the line itself, let me show you what's going on with that transition. 47

47

There's a couple of things in here to have a look at. 48

48

First of all, we've got a little bit of blending that 49

49

Unity is trying to do from one state to another. 50

50

Now that ends up looking a little bit crumby because we've got nice, 51

51

clean 2D animation here. 52

52

We don't need it to blend as we might do with 3D animation. 53

53

So I'm going to open up Settings and 54

54

just turn Exit Time to 0 and the Fixed Duration to 0 as well. 55

55

Now there won't be any of that blending that needs to take place. 56

56

So we can probably just do the transition duration if we wanna be 57

57

a little bit quicker about it. 58

58

So we've put that to 0. 59

59

Now we have this movement into Running. 60

60

We need to say what condition is going to be met for this trigger to take place. 61

61

So in our Animator window, make sure Parameters is clicked. 62

62

We're gonna click the + icon just here, and we've got a choice of Float, Int, 63

63

Bool, and Trigger. 64

64

For now we're going to set up a Bool, and this Bool we will call Running. 65

65

We come back over onto our Conditions. 66

66

Make sure you have your transition selected here, click +. 67

67

And the only condition we've got at the moment is Running. 68

68

That's the only one we've set up over here. 69

69

And Running is true. 70

70

So basically, it's saying when the Bool of Running is true, 71

71

then we transition into the state of Running. 72

72

That's pretty straightforward. 73

73

If we click on Running, right-click, 74

74

Make Transition, we can transition back to Idling. 75

75

And a micro challenge for you. 76

76

What's the condition where we will transition from Running back to Idling? 77

77

That would be + Running is false, of course. 78

78

Same as before, I'm gonna make the Transition Duration 0 79

79

just to make sure we don't have any of that overlap here. 80

80

I'll put this to 0 as well, okay, just so it's nice and clear this is gonna happen. 81

81

I just click straight into that other state without any blend. 82

82

Okay, so now we've got that flow going on. 83

83

This is all hooked up to the player still cuz the player has the Animator Controller 84

84

in here called Player, so it knows this straight away. 85

85

If we click on Play, you should see the player sitting there idling. 86

86

I'll just go back to my Scene view so I can get in nice and close. 87

87

The player's sitting there idling. 88

88

If we click on this, this is to simulate if we were to call it in code and 89

89

say, turn the Bool to true. 90

90

Now the player's running, run, run, run, run, run. 91

91

And then if we click on it to simulate, 92

92

now code's saying turn the Bool to false, then back to animation again. 93

93

So we've got this nice flow from state to state, very excellent. 94

94

Now the next state we're going to set up is going to be the climb ladder. 95

95

That's the other main state we'll have in our game. 96

96

Let's just go have a look at our sprite sheet to see which one that would be. 97

97

Climb ladder is pretty much just gonna be these two here. 98

98

So 14 and 15, I've got those in my sprites here. 99

99

So what I want you to do as a challenge is to implement climb and 100

100

run animation states, create the transitions from idle, and 101

101

create the triggers for each of the states. 102

102

So go ahead and do that for climb and run, and 103

103

I'll see you back here when you've got that done. 104

104

Okay, so it was 14 and 15, I believe. 105

105

Let's find those. 106

106

There's 14 and 15 [SOUND] excellent, looks like a wonderful ladder climbing. 107

107

Right-click, Create > Animation, if I can find it, there it is, Animation. 108

108

This will be Climbing animation. 109

109

Drag that into our state machine in here. 110

110

From Idling, right-click, Make Transition into Climbing. 111

111

And I'll do the other one straight away, Make Transition back to Idling. 112

112

Click on this first one and just tidy up little of this. 113

113

You don't have to tidy up the blending, but as I've mentioned, 114

114

I like to do this, dot dot dah, wonderful. 115

115

Click on the + button and create another Bool, which will be Climbing. 116

116

Climbing is our parameter. 117

117

Then over on here, 118

118

our condition going from Idling to Climbing should be Climbing is true. 119

119

And then if we click on the other direction, 120

120

the condition of Climbing should be false. 121

121

And again, just tidy this up. 122

122

Okay, and you can see in here, we've got something that's called Has Exit Time. 123

123

Basically, this is saying, 124

124

you've got a number of ways of exiting this animation state. 125

125

One way is if you want the animation to play. 126

126

And then as soon as the animation finishes playing, 127

127

go back or transition back to the state. 128

128

Then you can use Exit Time. 129

129

So it said there's ten frames of animation. 130

130

You do those ten frames. 131

131

If Has Exit Time is on, 132

132

after the ten frames, it can return back to the other state. 133

133

So I wanna click Has Exit Time off cuz what we're using here is the condition of 134

134

the Bool to say when the transition takes place. 135

135

Have a look over here, turn off Has Exit Time there, and 136

136

same with all these other ones, just turning off Has Exit Time. 137

137

We only want that in a situation where we definitely end after we play a particular 138

138

single shot animation. 139

139

Now let's click Play, see if we've hooked all this up correctly. 140

140

The character should be defaulting to Idle. 141

141

And you can see the Idle clicking through here. 142

142

This is the state we're in. 143

143

It's playing through the frames. 144

144

We click on Running, yes, it runs. 145

145

And Climbing, no, it's not climbing at the moment. 146

146

What have we done wrong here? 147

147

Let's have a look at our transitions. 148

148

We have Running is true. 149

149

You're probably yelling at the screen, saying, Rick, you put in Running. 150

150

You should've put in Climbing. 151

151

There we go, we've found it. 152

152

Let's click Play here. 153

153

Thank you for yelling at the screen, 154

154

if you did yell at the screen in that instance, Climbing, yep. 155

155

And it's stuck, which says that we are not looping, if I am correct. 156

156

We haven't clicked on looping time in there. 157

157

That stays in play mode, which is all good. 158

158

Now that we've got it, our character can run and our character can climb. 159

159

So these are all the states that we need for now. 160

160

As our game gets more complex, we might wish to add in rolling or shooting or 161

161

jumping. 162

162

But for now, 163

163

all we need functionality-wise is the player can run and the player can climb. 164

164

And after we put all of that gameplay functionality in, 165

165

we might revisit our states in here and our animations and add more in. 166

166

But we don't want to overinvest in this until we've got our core gameplay created 167

167

and we know how it all fits together and how it looks. 168

168

So great work in this video, and I'll see you in the next video.
