Destroying a wall.

Questions & Answers
1

I currently have this code.

using UnityEngine;

public class gameover : MonoBehaviour {	
    void OnTriggerEnter(Collider thisObject) {		
        if (thisObject.tag == "Player" ){ 
            Application.LoadLevel("Intro");
        }
    }
}

I have added this code to a projectile that is launched towards the player. Currently it just hits the player, does nothing and keeps going. I cannot tick the projectile as the trigger because if I do a 2nd script I have on it will delete everything it touches? I’m hoping someone can help me with this.

In answer to stingman’s comment :

This is my wall destroy code. At the moment it now just goes right through the wall. I have ticked is trigger for the wall that is meant to be destroyed.

using UnityEngine;

public class DestroyWall : MonoBehaviour {
    void OnTriggerEnter(Collider thisObject) {
        if (thisObject.tag == "destructableWall" ){ 
           Destroy (thisObject);
        }
    }
}

also with that other script am i meant to add it to my player or projectile and then tick the opposite.

If the wall is a trigger, the projectile must be a rigidbody - is it? And you should use Destroy(thisObject.gameObject), since Destroy requires a GameObject reference (and thisObject is a Collider). But you would have problems with the gameover code, because making the player a trigger definitely isn’t a good idea.

Anyway, that’s not the best way to do what you want: ideally, the projectile should be a rigidbody and the wall a regular collider (not trigger). You should also use OnCollisionEnter in both cases (assumed both scripts attached to the projectile):

using UnityEngine;

public class gameover : MonoBehaviour { 
    void OnCollisionEnter(Collision coll) {   
        if (coll.gameObject.tag == "Player" ){ 
            Application.LoadLevel("Intro");
        }
    }
}

// and in the DestroyWall script:

using UnityEngine;

public class DestroyWall : MonoBehaviour {
    void OnCollisionEnter(Collision coll) {   
        if (coll.gameObject.tag == "destructableWall" ){ 
           Destroy (coll.gameObject);
        }
    }
}

Notice that both scripts could be combined in a single one, improving the performance:

using UnityEngine;

public class ProjectileScript : MonoBehaviour {
    void OnCollisionEnter(Collision coll) {
        String hitTag = coll.gameObject.tag;
        if (hitTag == "destructableWall" ){ 
            Destroy (coll.gameObject);
        }
        else
        if (hitTag == "Player"){
            Application.LoadLevel("Intro");
        }
    }
}
