Apply Damage To Player On Collison With Specific Game Object

Questions & Answers
1

Yes I do realize this question has been asked many time before. but i have never found one that fits my needs, and yes i am new and i am taking this project 1 step at a time

  1. Enemy Object name = enemy

  2. player is Main Camera

  3. Health Script

    var Health = 100;

    function ApplyDammage (TheDammage : int)
    {
    Health -= TheDammage;

    if(Health <= 0)
{
	Dead();
}

    }

    function Dead()
    {
    Destroy (gameObject);
    }

  4. Raycast Shooting Script

    var Effect : Transform;
    var TheDammage = 100;

    function Update () {

     var hit : RaycastHit;
 var ray : Ray = Camera.main.ScreenPointToRay(Vector3(Screen.width*0.5, Screen.height*0.5, 0));
 
 if (Input.GetMouseButtonDown(0))
 {
 	if (Physics.Raycast (ray, hit, 100))
 	{
 		var particleClone = Instantiate(Effect, hit.point, Quaternion.LookRotation(hit.normal));
 		Destroy(particleClone.gameObject, 2);
 		hit.transform.SendMessage("ApplyDammage", TheDammage, SendMessageOptions.DontRequireReceiver);
 	}
 }

    }

  5. Current attempt that dont work
    var health = 4;
    var damage = 1;
    var wait_time = 2;
    var lock = 0;

     function OnCollisionEnter(hit: Collision){
 if(hit.gameObject.tag == "enemy" && lock == 0)
 		{
 		hit.transform.SendMessage("ApplyDammage", 100, SendMessageOptions.DontRequireReceiver);
 	    }
 	    }

tag and name are two different things… make sure you create a TAG called enemy and give your object that tag… Or change your code to:

if(hit.gameObject.name == "enemy" && lock == 0)

also, OnCollision functions may require a Rigidbody to work… there is a matrix toward the bottom of this link to show what will send a collision message and what won’t:

you may be better off using a trigger. just set the collider on the object to “isTrigger” and change your “OnCollisionEnter” to “OnTriggerEnter”… You will still need a Rigidbody (or CharacterController), either way… (And for the record, there are LOTS of examples out there which explain this, you probably should look harder…)
