Simple timer to minus a Var in Javascript

I tried using a tutorial but it just doesn't seem to work for me or what im looking for, so in JavaScript could I make a simple timer that every 10 seconds reduces the var MonsterHealth: int; by 5?

 

You can do this in a few ways. The first thing that crosses my mind is invokeRepeating() (read here how this function works) but it doesn't give you a lot of power over the call. Once it starts calling the function you specify (a function that reduces the health, in your case) you can't change the amount of time and you can't stop (you can, but then you cancel every invoke repeating running). So I'll describe how to do this by hand.

Code (JavaScript):

1. var timer : float = 0;
2. var rate : float = 10;
3. var reduceHealth : boolean = true;
4. function Update(){
5.     if( reduceHealth && timer >= rate ){
6.         monsterHealth -= 5;
7.         timer = 0;
8.     }
9.     timer += Time.deltaTime;
10. }
11.  

You could, of course, set timer to 10, reduce deltatime from it and ask if it's equal or smaller than 0. It's all the same.

Hope this helps.

 

No, you just CancelInvoke("MyFunction") and it only cancels that particular one.

Thanks that worked awesomely

 

Thanks for the info! that makes invokerepeating much more useful, actually.
