few question about quaternion slerp

hi everyone.

i have a coroutine that looks like this

Code (CSharp):

1.     private IEnumerator StartRotation(
2.         Quaternion curPos,
3.         Quaternion targetPos,
4.         float t
5.     )
6.     {
7.         float counter = 0;
8.         while ( counter < t)
9.         {
10.             counter += Time.deltaTime;
11.             transform.rotation = Quaternion.Slerp(curPos,targetPos,counter);
12.             yield return null;
13.         }
14.     }

well, it's working, but i need two more things and i can't figure out hot to do it...

- i want to be able to pingpong gameobject between this two rotation
- maybe is a noob question but if i want that slerp complete the rotation in 1 second, ho i should set it?

i'm confused.. someone can help me please?

thank's you in advance

 

Quaternion.RotateTowards might be more suitable for what you're trying to do.

You can also use Quaternion.Angle to get the angle between quaternions, and you can use that to figure out how many angles to update each time you call Quaternion.RotateTowards so that you reach the target in a specific amount of time.

 

if you want to complete a rotation is 1 sec:
(this takes the shortest path so you can't use it to do a 360)

Code (CSharp):

1. Transform obj;
2. Quaternion startRot;
3. Quaternion endRot;
4. float step = 0.0f;
5. while(step < 1.0f){
6. obj.rotation = Quaternion.Slerp(startRot, endRot, step);
7. step += Time.deltaTime;
8. yield return null;
9. }

 

in case i want a 360 degrees rotation?

 

In that case, you're better off rotating around an axis rather than trying to go from quaternion to quaternion.

 

The point is i want a some kind of fake swinging movement, and slerp should be goot on this.

But i actually have teo problem,

- i want to start it like an impulse then slow down over time
- and when i’m trying to go from -90 degrees to 135 it will cut and pass throught -180 degrees and not 0


I’l check rotatetowards
