Mine - Landmine with script

Unity Engine
1

I build a simple mine:

The player (Object with the tag player) collides an it goes off, dealing some dammage

var sound : AudioClip;
var soundVolume : float = 2.0;

var explosion : Transform;
var spawn : Transform;


function OnTriggerEnter(other:Collider) {
	if (other.tag != "Player")
		return;											// return beendet hier die Funktion			fals das Tag nicht Player
	
	if (sound)											// ansonsten gehts hier weiter
		AudioSource.PlayClipAtPoint(sound, transform.position, soundVolume);
	
	Destroy(gameObject);
	
	if (explosion) 
	Instantiate (explosion, transform.position, transform.rotation);
	
	if (spawn) 
	Instantiate (spawn, transform.position, transform.rotation);
		
}

It plays a soundfile, kills itself, spawns some debris and an explosion which does the damage

One problem is: now it uses it’s collider as trigger but i want it to be a riggidbody to be able to bounce of the floor. And at the moment you can’t shoot it. It deals but does not receive dammage.

Simply change:

function OnTriggerEnter(other:Collider)

to

function OnCollisionEnter(other:Collider)

…then you can use it as any rigid body.

you should look at the damage receiver script in the FPS-Demo. Its a good script to control damage. :smile:

thanks alot. It makes sense to me that it should react to a collision and not via a trigger.

But now how do i make it distinguish to which tag it reacts. Before i made it blow only with player tagged objects

function OnCollisionEnter(collision : Collision) {
	if (collision.tag != "Player")
		return;

This part does not work anymore: if (collision.tag != “Player”)

I did look at the fps tutorial and came up wit a not very graceful solution:

I use 2 parts the Mine and the Trigger

The Mine is a RiggidBody

var explosion : Transform;
var spawn : Transform;



function BlowUp () {
	print ("BOOOM!!!");
	
	Destroy(gameObject);
	
	if (explosion) 
	Instantiate (explosion, transform.position, transform.rotation);
	
	if (spawn) 
	Instantiate (spawn, transform.position, transform.rotation);
		
}

The red part on top is the trigger it’s collider is set to trigger ( seems they should not touch each other)

var sound : AudioClip;
var soundVolume : float = 2.0;

var target : Transform;



function OnTriggerEnter(other:Collider) {
	if (other.tag != "Player")
		return;											// return beendet hier die Funktion			fals das Tag nicht Player
	
	if (sound)											
		AudioSource.PlayClipAtPoint(sound, transform.position, soundVolume);
	
	print ("BUM");
	
	if (target.GetComponent("MineV2") != null)			
		target.GetComponent("MineV2").BlowUp();	

}

feel like a workarount to me but does the job
But i am always interested in better solutions. :wink:
