Bonjour,

mon programme est ceci mais cela me met "please fix compile errors before créating neuw script compoment" et si je change un truc les variables ne s'affiche pas

#pragma strict

var bulletCasing : Rigidbody;
var ejectSpeed : int = 100;
var fireRate : float = 0.5;
private var nextFire : float = 0.0;
private var fullAuto = false;

function Update () {

if (Input.GetButton("Fire1") && Time.time > nextFire) {
nextFire = Time.time + fireRate;
var bullet : Rigidbody;
bullet = Instantiate(bulletCasing, transform.position, transform.rotation);
bullet.velocity = transform.TransformDirection(Vector3.left * ejectSpeed);
}

if (Input.GetKeyDown("v")) {
fullAuto = !fullAuto;
}

if (fullAuto == true) {
fireRate = 0.10;
} else {
fireRate = 0.5;
}
}
