Kill object after time
So, I have a projectile prefab that is shot both by the player and by the turrets of my game. When I instance the prefab in the two different scripts, I give them two different tags, "wormProjectile" and "enemyProjectile". Because I didn't want to projectile to live forever, I attached a script to the prefab meant to kill it after a certain amount of time. I wanted the projectiles fired by the turrets to live a different length of time than the ones fired by the player, so I tried using the following script:
var lifetimeP = 1.0;
var lifetimeE = 2.0;
function Awake ()
{
if (gameObject.CompareTag ("wormProjectile"))
{
Destroy (gameObject, lifetimeP);
}
if (gameObject.CompareTag ("enemyProjectile"))
{
Destroy (gameObject, lifetimeE);
}
}
But it never goes into the if statements. I am sure my mistake is something simple, but can anyone help me? Thank you! I really appreciate it.
well, your running this in Awake(). Awake gets called once, when the script is loaded (or "woken up" as i like to think of it). You need it to run every time a shot is fired (inside your shoot function?).
I suspect Awake is called during Instantiate, and your problem seems to confirm that: since you set the tag after Instantiate, Awake only sees the original prefab tag.
A direct solution would be to change the routine from Awake to Start. A better solution, however, would be to fire the projectile and call Destroy in the same code - each shooting code would set the appropriate life time right after the projectile birth.
Your worm shooting script, for instance, would become something like this:
...
bullet = Instantiate(prefab, ...);
Destroy(bullet, 1); // if bullet isn't a GameObject, use bullet.gameObject
bullet.tag = "wormProjectile";
...
Thank you both! That worked great. I will get the hang of this eventually.
