Script error?

[anon_71564648]

what im trying to do is spawn a bullet hole gameobject where the rocket hits, and i get this error.

Assets/Assets/WeaponScripts/Rocket.js(19,47): BCE0023: No appropriate version of ‘UnityEngine.Object.Instantiate’ for the argument list ‘(UnityEngine.GameObject, UnityEngine.ContactPoint, UnityEngine.Quaternion)’ was found.

this is my script

// The reference to the explosion prefab
var explosion : GameObject;
var timeOut = 3.0;
var bulletHole : GameObject;

// Kill the rocket after a while automatically
function Start () {
Invoke(“Kill”, timeOut);
}

function OnCollisionEnter (collision : Collision) {
// Instantiate explosion at the impact point and rotate the explosion
// so that the y-axis faces along the surface normal
var contact : ContactPoint = collision.contacts[0];
var rotation = Quaternion.FromToRotation(Vector3.up, contact.normal);
Instantiate (explosion, contact.point, rotation);
// create a bullet hole object at hit point and rotation
var newBulletHole:GameObject = Instantiate(bulletHole, contact, rotation) as GameObject;

// And kill our selves
Kill ();
}

function Kill () {
// Stop emitting particles in any children
var emitter : ParticleEmitter= GetComponentInChildren(ParticleEmitter);
if (emitter)
emitter.emit = false;

// Detach children - We do this to detach the trail rendererer which should be set up to auto destruct
transform.DetachChildren();

// Destroy the projectile
Destroy(gameObject);
}

@script RequireComponent (Rigidbody)

As the error message says, there is no Instantiate function with arguments : GameObject, ContactPoint, Quaternion.

Unity - Scripting API: Object.Instantiate

Have a more attentive look, you will see.

On the other hand…

ContactPoint.point is listed as a Vector3, so it’s easy to be confused.

Unity - Scripting API: ContactPoint.point

You’d think that ContactPoint.point as Vector3 should fit this override:
static function Instantiate (original : Object, position : Vector3, rotation : Quaternion) : Object

And it does!

Knowing that it IS possible to use ContactPoint.point, and I assume, your explosion works fine, what’s the difference between the two lines of code?

Let’s put them side by side:
Instantiate (explosion, contact.point, rotation);
Instantiate (bulletHole, contact, rotation);

Simple oversight!
