Transform.LookAt and Back!
How do I make a character turn in the direction of the camera once (to attack player), then turn back to the direction at which it was looking? The following attempt failed:
function Update () {
if (calculateDistance(GameObject.Find("Main Camera"), this.gameObject) > 4f) {
if (rotation.y != 10001) {
//this.gameObject.transform.eulerAngles = rotation;
//this.gameObject.transform.LookAt(oldForward, oldUp);
this.gameObject.transform.localRotation = rotation;
addWalkingForce();//MOVE FORWARD AGAIN
rotation.y = 10001;
}
this.animation.Play ("Walks");
}
else {
this.animation.CrossFade ("Attacks");
oldForward = this.gameObject.transform.forward;
oldUp = new Vector3(Vector3.up.x, Vector3.up.y, Vector3.up.z);
rotation = this.gameObject.transform.localRotation;
rigidbody.velocity = Vector3.zero;//KILL FORWARD MOVEMENT
this.transform.LookAt(GameObject.Find("Main Camera").transform, Vector3.up)
}
Get the rotation before, store it, then make it rotate, then make it rotate back to the original position...
I'm surprised no one had anything to say about it. But the following worked. I added the time test to prevent it from storing the rotated forward before the animation could be said to be "Walks" (as it was cross fading, I suppose). Other than this little bit, the only thing I can tell was wrong was that transform.forward gives you the worldspace vector but not the actual position (hence the addition). I hope this helps someone.
PS: How frustrating is this system of trying to get code colored and indented here? Come on, guys, come up with brackets, or something.
private var oldForward : Vector3;
private var lastTimeStoredForward : float;
function calculateDistance(from : GameObject, to : GameObject) : float { var origin : Vector3 = from.transform.position; var destination : Vector3 = to.transform.position; return Mathf.Sqrt((origin.x-destination.x)(origin.x-destination.x) + (origin.y-destination.y)(origin.y-destination.y) + (origin.z-destination.z)*(origin.z-destination.z)); } function addWalkingForce() { this.rigidbody.AddForce (this.gameObject.rigidbody.transform.forward*20); } function Start() { addWalkingForce(); oldForward.y = 10001; lastTimeStoredForward = -99999; } function Update () { if (calculateDistance(GameObject.Find("Main Camera"), this.gameObject) > 4f) { if (oldForward.y != 10001) { this.gameObject.transform.LookAt(oldForward, Vector3.up);
addWalkingForce();
oldForward.y = 10001;
}
this.animation.Play ("Walks");
}
else if (animation.IsPlaying("Walks")) { if (lastTimeStoredForward+1 < Time.time) { oldForward = new Vector3(this.gameObject.transform.position.x+transform.forward.x,transform.position.y, this.gameObject.transform.position.z+transform.forward.z);//WHY DOESN'T THIS WORK? lastTimeStoredForward = Time.time; } this.animation.CrossFade ("Attacks"); rigidbody.velocity = Vector3.zero; var toLook : Vector3 = GameObject.Find("Main Camera").transform.position; toLook.y = this.gameObject.transform.position.y;//DO NOT ROTATE AROUND X-AXIS this.gameObject.transform.LookAt(toLook, Vector3.up); } } function OnCollisionEnter(collision : Collision) { if (collision.gameObject.name.StartsWith("ZombieLevel")) { Debug.Log("Collided against level."); this.gameObject.transform.Rotate(0, 180, 0); } }
