Destroy object question!

How i can destroy an object when out of camera view?

Thx you in advance,

You could make a large trigger that when the objects leave the "sphere of influence" of (OnTriggerExit) they get sent a message (that ultimately leads to a function that kills them).

This would have more control than say, immediately killing something off screen.

I have never tried this, but mabye:

function OnBecameInvisible () 
    //Destroy your object here.

Dont touch

if (!gameObject.renderer.isVisible)

Like so :)
