How do I rotate object smoothly
I understand the basic concept of rotating an object
function OnTriggerEnter(otherCollider : Collider) {
if (otherCollider.tag == "RotationTrigger") {
transform.Rotate(0,90,0);
}
}
but how do I do it smoothly over time, say I was opening a hatch or door and did not want it to just snap open to 90 deg.
Any help appreciated
The "easiest" way to do it is to use something like iTween
HOW DO YOU DO ROTATE AROUND IN ITWEEN!!! IVE BEEN SEARCHING FOR 2 FRIC$$anonymous$$IN HOURS
Though iTween is simple, I prefer a good old fashioned Lerp. For Rotational Lerping see Quaternion.Lerp()
If you don't get Quaternions (don't worry, to be honest I'm still a little uncertain of them myself) you can do some playing around with a Euler Angle representation to make it easier.
Hope that helps.

Here is the definition. That way you can Rotate over Time. Work great.
As I see you have four more options:
LeanTween plugin.
You can use it like: (untested code)
LTDescr descRotate = LeanTween.rotateX(this.gameObject, 90.0f, 0.5f);
descRotate can be consumed later for dealing with other parameters of this animation.
Use Update() function: (untested code)
void Update() { transform.Rotate(20.0f * Vector3.forward * Time.deltaTime); }Using Animator Component:
Have a look at this tutorial for creating animations. See section Creating Animations, under mouse:Sprite you can add rotation curves and whenever needed you can run animation.
Using Coroutine.
Have a look at this example
Hope it helps!
