How to make a bullet explode on impact

Questions & Answers
1

I am making a tank game in which I would like the bullet to be fired and explode on impact with an enemy AI tank. The script I am currently using for the bullet is:

var colision = 0;
var bulletspeed = 400;
var bullet : Transform;
function Update () {
if(Collision){
if(colision == 3){
}
else{
colision +=1;
rigidbody.velocity = transform.TransformDirection(Vector3(0,0,bulletspeed));
}
}
else{
rigidbody.velocity = transform.TransformDirection(Vector3(0,0,bulletspeed));
}
}

I have also assigned the bullet prefab this script to make it explode on impact with the enemy tank:

var explosion : ParticleEmitter;

function OnCollisionEnter (col : Collision) {

 Instantiate(explosion, transform.position, transform.rotation);

 Destroy(gameObject);

}

But the bullet seems to be exploding as soon as it leaves the muzzle of the tank’s barell. I think this is because the bullet is touching the tank that has just fired it, but I can’t find any part of the script to adjust to make it appear just in front of the barell so that it can continue on its trajectory and hit the enemy tank.

Cheers

The bullet is probably colliding with the barrel. You can check the name of the collider before instantiating something, so like

var explosion : ParticleEmitter;
function OnCollisionEnter (col : Collision) {
     if(col.name !="Tank"){
            Instantiate(explosion, transform.position, transform.rotation);
            Destroy(gameObject);
     }
}

Thanks, but it hasn’t solved the problem. I have many variations such as:

var explosion : ParticleEmitter;

function OnCollisionEnter (col : Collision) {



 if(col.name !="Tank") Instansiate = false;

 

 if(col.name !="EnemyTank") Instansiate = true;

 

 Instantiate(explosion, transform.position, transform.rotation);

 Destroy(gameObject);

}

but it still explodes as soon as it is fired.
