We are now going to look at another type of structure that is just as fundamental as conditions: loops!

A loop allows instructions to be repeated several times. There are several types that we will see in this part.

while loop

The while loop has a syntax similar to the if loop seen above. It allows an instruction block to be executed as long as a condition is met.

Here is an example :

This code will display in the logs when executed: > Counter is worth 1 Counter is 2 Counter is 3 Counter is 4 Counter is worth 5

do while loop

The do while loop is similar to the while loop, except that the condition occurs at the end, so the body of the loop is always executed at least once:

A possible display of the execution of the program: > x: 0.85712

for loop

Another slightly more complex type of loop exists, it looks like a while loop but more condensed. You will see in use that depending on the use case it is more practical to use a for or a while.

The for loop consists of three optional parts:

• Initialization: assigning a starting value to a counter variable;
• The condition: as long as it is valid, the loop continues to run;
• Incrementation: increase (or decrease as appropriate) the value of your counter variable.

Example of a for loop:

This code will show in the logs: > The counter i is 1 The counter i is 2 The counter i is 3 The counter i is 4 The counter i is 5

Attack multiple times in a row

Our leek has between 10 and 13 PT (thanks to Motivation) and the Pistol only costs 3 PT, so it can be used 4 times at most.

We use a for loop to execute the useWeapon function 4 times in a row:

Here our variable i will have the values 0, 1, 2 and 3 so the loop will do 4 iterations.
