All language subtitles for 2. GDScript Intro Operators

Now let's look at operators.
1

With variables alone
2

we cannot do much.
3

Not even store data, in fact, not because they cannot.
4

But because we need to use an operator to actually assign a value to a variable.
5

Now, let's look at the code here and let's assign two values to two variables and then use the addition
6

operator to add these two values and assign the new value in the third variable.
7

So first we have "a" which is 1 because it is an operator assign, then we have "b" and then we have "c",
8

which is the sum of "a" plus "b".
9

So the order of the execution of this is of course "a" + "b", and then the final result gets assigned
10

to "c". You can print "c", so you can see that the number will be three.
11

in this case. There are other operators that you should know of: addition(+), subtraction(-), multiplication(*)
12

and division(/).
13

All of these operators work exactly like in math, with the observation that the division cannot be
14

divided by zero.
15

It will result in an error.
16

Not all of the operators handle calculations.
17

For example, we have the logical operators: AND(&&) and OR(||) what they do is basically they handle own unique
18

variable type called boolean, which can be either true or false as following.
19

For example, if you use the AND operator, it can also be as this symbol &&.
20

If we have true && true, it will be true.
21

If we have true && false => false, false && false => it will be false.
22

For example, this is good in conditions like is the AI moving to a particular target AND also is the AI
23

having a particular health.
24

Then it's true that otherwise it's false.
25

And the OR operator is a little different, of course, because true || true equals true, but true || false
26

equals true.
27

So the difference is that only one of the conditions needs to be true
28

in order for the whole statement to be true. We can put it to the test and see the result.
29

Of course this is AND so true and false will be equal false and this is how we can actually use them.
30

Let's see, we have a variable called is enemy visible and true?
31

And then in the next section when we will be discussing about flow control, we will see how to get
32

the most out of these operators.
