Need Help Destorying Specific Object C#

Unity Engine
1

I’m making a 3D platformer and I’m trying to use a raycast to destroy things like blocks and enemies. I’ve had some success with using triggers for this but it seems to not work as well as it should so I thought a raycast might work better. I’ve managed to destory my PickUpObj, but it also destroys all PickUpObj’s in the scene. I would like it to only destroy the one that I’m hitting. Here us my code:

Vector3 upward = transform.TransformDirection (Vector3.up) * 10;
        Debug.DrawRay (transform.position, upward, Color.green);


if(Physics.Raycast(transform.position, upward ,out hit)){
       if(hit.collider.gameObject.tag == "pickup"){
       Destroy(GameObject.Find("PickUpObj"));
       }

GameObject.Find gives you a reference to some object named PickUpObj in the scene - and it doesn’t care where it finds it. What you need is a reference to the specific one you hit, and you have it - you’re already using it in the line above! Try Destroy(hit.collider.gameObject);

Friggin’ awesome! Thanks! I’m glad that was such an easy fix. I had a feeling the answer was in that line somewhere I just didn’t know what it was. I’m getting there!

Why don’t you just get the GameObject you hit from the hit.

hit.collider.gameObject? Using GameObject.Find(string) is very expensive.

By the way, how do I make my code appear in that grey box that every else’s does?

Thanks Polymorphik! I actually just started to learn raycast yesterday so a lot of it is still Greek to me. :stuck_out_tongue:

Perfect. Thanks!
