Rotation problems with VIDEO, Part 2

Unity Engine
1

Well, I have been working on a character animation program for tablet devices for a while now called “Touch Animator”. The biggest problem I am having is that when an object animates, the rotations do not happen in a predictable or useful fashion. I have tried Quaternion.Slerp, setting the angles directly, and all sorts of other solutions. Maybe I am just not implementing these correctly. Anyway, i posted a video which clearly lays out the problem andthe script that controls the rotation. After searching the forumsI have found that several other people have similar issues so a solution could benefit us all.

I told you before to use Quaternions and slerp. Did you try this?
I also told you that Euler is pronounced Oi-ler :slight_smile:
here’s an example:
WebPlayer

import System.Collections.Generic;
private var animationFrames : List.<Quaternion>;
private var isAnimationPlaying : boolean = false;
function Start()
{
	animationFrames = new List.<Quaternion>();	
	animationFrames.Add(transform.rotation);
}
function OnGUI()
{
	if(GUI.RepeatButton(Rect(0,10,32,32),"-"))
	{
		transform.eulerAngles.y -= 1;
	}
	if(GUI.RepeatButton(Rect(50,10,32,32),"+"))
	{
		transform.eulerAngles.y += 1;
	}
	if(GUI.Button(Rect(0,50,40,32),"Key"))
	{
		animationFrames.Add(transform.rotation);
	}
	if(GUI.Button(Rect(50,50,40,32),"Play"))
	{
		if(!isAnimationPlaying)
			PlayAnimation();
	}
}
function PlayAnimation () 
{
	var i : int = 0;
	isAnimationPlaying = true;
	while (i < animationFrames.Count-1)
	{
		transform.rotation = animationFrames[i];
		yield Rotate(animationFrames[i+1],1);
		i++;
	}
	isAnimationPlaying = false;
}

function Rotate (endRotation : Quaternion, time : float) {
    var startRotation = transform.rotation;
    var rate = 1.0/time;
    var t = 0.0;
    while (t < 1.0) 
    {
        t += Time.deltaTime * rate;
        transform.rotation = Quaternion.Slerp(startRotation, endRotation, t);
        yield;
    }
}
