Hel with object rotation

hi everyone.
Let me explain what issue i have.

I want to rotate an object and let it flip from an position to another, like a pendulum, and what i have is this

Code (CSharp):

1. Vector3 movePos = new Vector3(0.0f,1.0f,0.0f);
2.  
3.         float angle = Mathf.Sin(Time.time * Mathf.PI * 0.5f) * targetangle;
4.        
5.         _playerArray[id].transform.rotation = Quaternion.Euler(angle,0.0f,90.0f);

That is working well, but nio at all when i want to increase that target angle object do a little strange twitch.

How to make it smoth?

Anyone can help me?

 

It will increase smoothly if you increase the targetAngle smoothly. Instead of changing it from 10 to 20, use a coroutine to slowly move it there in smaller steps.

 

Thank’s u, sometimes i’m so stupid..
