Rotate the body of the character in 3d person character

[THENextStep]

when i rotate the character it shake i try so many methods i try with vector and with quaternion (i used Cinemachine) can any one help

In the line I highlighted you are setting the starting rotation to the target value. This will constantly change as unity tries to lerp with a moving start point. This is probably the cause of the shaking.

Please paste in the code going forward. It is hard to help with screen shots.

no, you probably think they are the same var but they aren’t, the start point is the current rotation of the body (transform in body that cam follow (Cinemachine)) the end rotation is the mouse move value, the code that you are referring to is a recentering code that will not apply unless the timer ends… so my problem is when I rotate the mouse fast the body of the character hesitate

My English is not that good … so forgive me if I can’t explain the problem that well

problem in rotation

The run window is just a preview of what the game will look and feel like. Sometimes it has a bit of lag. If your code is working as intended, then try building the game to know for sure if there is an issue. You added a mouse sensitivity setting, so you can adjust that if needed.
