Bullets Based on Orientation
So I'm trying to set up a system where I have "GunNodes" which spawn bullets and fire them in the direction that the nodes are facing. So far, I've been having some trouble.
BulletCode:
function Update () {
LifeTime += Time.deltaTime;
transform.position += Vector3.forward * BulletSpeed * Time.deltaTime;
if(LifeTime >= Range){
Destroy(gameObject);
}
GunCode:
function FireGuns (){
FiringCoolDown = true;
Instantiate(BulletObj, GunNode.position, GunNode.rotation);
Handheld.Vibrate ();
yield WaitForSeconds(FireRate);
FiringCoolDown = false;
}
Particularly, how can I spawn an object and cause it to move in the direction that another object is facing?
In your bullet code, change this line:
transform.position += Vector3.forward * BulletSpeed * Time.deltaTime;
to this:
transform.Translate(Vector3.forward * BulletSpeed * Time.deltaTime, Space.Self);
Keep in mind that bullets that move in this way will not respond to colliders, or in fact any kind of collision detection. You will have to add a second step that sends a linecast between the bullet's position before and after the translation to manage collisions.
Wow that works fantastic!
Now, about the linecast. I'm developing this game for Android, any thoughts on how much impact a linecast will have on framerate if it's being called constantly?
Not significant. It's way more efficient than normal collision detection, anyway.
