Error with Rotating script
var waypoint:Transform[]; var speed : float =5; private var currentWaypoint : int; var loop:boolean=true; var rotationSpeed:float=5;
function FixedUpdate () { if (currentWaypoint<waypoint.length){ var target = waypoint[currentWaypoint].position; var moveDirection : Vector3 = target - transform.position;
var velocity = rigidbody.velocity;
if(moveDirection.magnitude<1){
currentWaypoint++;
}
else{
velocity = moveDirection.normalized*speed;
}
}
else{
if(loop){
currentWaypoint=0;
}
else{
velocity = Vector3.zero;
}
}
rigidbody.velocity = velocity; transform.LookAt(target); transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation((transform.position-target).normalized), Time.deltaTime * rotationSpeed); }
this is an AI script and the
transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation((transform.position-target).normalized), Time.deltaTime * rotationSpeed);
Is supposed to make it rotate smoothly , but its making it spaz left and right and generally doesnt have the effect i want , what am i doing wrong
Basically i found the problem
transform.LookAt(target);
transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation((transform.position-target).normalized), Time.deltaTime * rotationSpeed);
i had both a LookAt and the Slerp with the other LookAt , so i removed the first line and its ok also it went backwards but i found the problem. it was (transform.position-target) while it should be (target-transform.position)
I've found a Slerp/Lerp is more complex than it originally seems.
First of all, your line transform.LookAt(target) will instantly snap your object's Z-axis as looking toward that object with no transition effect. That may explain the first spaz motion.
Now for the Slerp. This is how I do it with a Mathf.Lerp function, which should work similarly.
float t = 0.0F; float hitPoints = 0; float maxHitPoints = 100; float buildTime = 30.0f; //Seconds
void Update() { //Or FixedUpdate if you want if ( hitPoints < maxHitPoints ){ t += Time.deltaTime; hitPoints = Mathf.Lerp(0, maxHitPoints, t / buildTime); } }
The problem is, with your line:
transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation((transform.position-target).normalized), Time.deltaTime * rotationSpeed);
Every time the Quaternion.Slerp is called, transform.rotation is changing. The next time Quaternion.Slerp is called, it uses a different transform.rotation to calculate with.
You want to try and eliminate the variables that change during the calculation if you want a smooth, linear transition.
so , what should i do, do you have a specific piece of code that would make my gameobject rotate smoothly?
I'm torn by giving you a specific set of code you can copy & paste. You should be able to solve the problem given this amount of information.
