Questions & Answers

Ok i need some help i have my script which will be attached to the knife of the player. So when my player hits the r button he will knife his opponent. This will be done by spawning the knife animated knife while moving so player wont get hurt as well. Here is my script for actually hurting my enemy.

var damage = 500;

function OnTriggerEnter (collision : hit)
{
    var hit : Raycast;
    if ( collision : hit )
    {
        hit.collider.SendMessageUpwards("ApplyDamage", damage, SendMessageOptions.DontRequireReciever);
    }
}

So what it does is it attacks the foe and kills them instantly.

Some points:

  • OnTriggerEnter have nothing to do with Raycasts
  • There is no type “hit” (even if collision should be the type it would be wrong since it’s Collision with capital C)
  • OnTriggerEnter does not take a Collision it takes the Collider that enters the trigger.
  • Your if statement… well, is completely wrong. The expression within the brackets should result in a boolean value (true or false). A colon has no use in the expression since it’s used to specify the type when declaring variables…

I think you want something like that:

var damage = 500;

function OnTriggerEnter ( other : Collider )
{
    if ( other.tag == "Player" ) // or what ever you want to identify the object
    {
        other.SendMessageUpwards("ApplyDamage", damage, SendMessageOptions.DontRequireReciever);
    }
}

this is what i tried but i still have a litle problem, if you double click really fast it hits twice!!!
