Straight Raycast Shooting
Can someone help me with my Raycast shooting. Now it shoots kind of randomly, and I want to it shoot exactly straight. Please help, I've tried everything.
var fireRate = 0.02;
var force = 10.0;
static var damage = 25;
var bulletsPerClip = 30;
static var clips = 3;
var range = 100;
static var bulletsLeft : int = 30;
private var hitParticles : ParticleEmitter;
private var nextFireTime = 0.0;
function Start () {
hitParticles = GetComponentInChildren(ParticleEmitter);
// We don't want to emit particles all the time, only when we hit something.
if (hitParticles)
hitParticles.emit = false;
}
function Update () {
if(Input.GetMouseButton(0))
{
Fire();
}
if (bulletsPerClip == 0)
{
Reload ();
}
if (Input.GetKeyDown ("r"))
Reload ();
}
function Fire () {
if (bulletsLeft == 0)
return;
if (bulletsPerClip == 0)
return;
// If there is more than one bullet between the last and this frame
// Reset the nextFireTime
if (Time.time - fireRate > nextFireTime)
nextFireTime = Time.time - Time.deltaTime;
// Keep firing until we used up the fire time
while( nextFireTime < Time.time && bulletsLeft != 0) {
FireOneShot();
nextFireTime += fireRate;
}
}
function FireOneShot () {
var direction = transform.TransformDirection(Vector3.forward);
var hit : RaycastHit;
// Did we hit anything?
if (Physics.Raycast (transform.position, direction, hit, range)) {
// Apply a force to the rigidbody we hit
if (hit.rigidbody)
hit.rigidbody.AddForceAtPosition(force * direction, hit.point);
// Place the particle system for spawing out of place where we hit the surface!
// And spawn a couple of particles
if (hitParticles) {
hitParticles.transform.position = hit.point;
hitParticles.transform.rotation = Quaternion.FromToRotation(Vector3.up, hit.normal);
hitParticles.Emit();
}
// Send a damage message to the hit object
hit.collider.SendMessageUpwards("ApplyDamage", damage, SendMessageOptions.DontRequireReceiver);
}
bulletsLeft--;
// Register that we shot this frame,
// so that the LateUpdate function enabled the muzzleflash renderer for one frame
m_LastFrameShot = Time.frameCount;
enabled = true;
// Reload gun in reload Time
if (bulletsLeft == 0)
Reload();
}
function Reload(){
if (clips > 0) {
animation.Play("reload");
yield WaitForSeconds(1.25);
bulletsLeft = 30;
bulletsPerClip = 30;
clips--;
}
}
I don't see anything wrong with your code. It is shooting out the forward of the object it is attached to. To help you visualize what is going on, insert between lines 55 and 56:
Debug.DrawRay(transform.position, direction * range);
Turn Gizmos on by clicking on the Gizmos button in the upper right corner of the Game window.
Is the issue what object is hit by the raycast, or how the object moves when you do the AddForceAtPosition()?
That "fixed" it! Thank you but now my idle animation is messed up, ins$$anonymous$$d of the gun being on the right side of the camera every time idle animation is played the gun is on the left side.
I don't think you have the information here for someone to help you solve your animation problem.
/ attach this script with your gun and put an empty game object as a child of gun which work as spawn point of bullet
