Question by sam32x · Sep 20, 2011 at 07:45 AM · something

variable help

heres my script

 var bullet : Rigidbody;
 var health = 3;
 var enemy : GameObject;
 
 function OnCollisionEnter(bullet : Collision){
 var health =- 1;
 }
 
 function Update(){
 if (health == 0);
 Destroy (enemy);
 }

i didnt know what to put for the variable near the end to destroy the enemy when its out of health so i just tried random stuff and found that this combination came up with no errors, except the cube is destroyed at the start of the game, i tried

 Destroy (enemy,3);

and that just destroyed the enemy 3 seconds after the start of the game

help plz.

Hi sam11x, sorry, I'm not sure to have understand your question very well...Do you say that the enemy is destroied at the beginning of the execution? In that case, I think that

 if (health == 0);

is wrong. To perform the "Destroy (enemy);" instruction inside the "if" statement you have to delete the ";" at the end of that line. So:

 function Update(){
 if (health == 0)
 Destroy (enemy);
 }

Let me know.

Of nothing, sam11x! But thanks @timsk as well...He remarked an important matter, that's the control about the possible-negative health. As he said, in the future, you could create more powerful weapons, that will inflict more than a damage. If the enemy's health will go under 0, he won't die with your actual script.

The correct usage for an if statement is:

 if(health ==0)
 {
 destroy (enemy);
 }

such a simple mistake :).

Also, i would change "health == 0" to "health
