Lerping Rotations Acting Strange,Lerping Rotations Acting weird

Questions & Answers

I want to Lerp an object to a different rotation, but when I set any of the target rotation values to a negative, it acts funny like this: [Lerping Issue - YouTube] When I set the value to a positive it works perfectly fine. My code:

void Update() {
        if (one == true) {
            transform.localEulerAngles =  Vector3.Lerp(transform.localEulerAngles, new Vector3(0, -90, 0), turnSpeed);
        }
}

,I want to make a patrolling system where the character rotates from point A to point B using Lerping, but for some reason, when I set one of the Vector3 values to a negative, it goes like this:

When I set the value to a positive number, it works as intended. My code:

transform.localEulerAngles = Vector3.Lerp(transform.localEulerAngles, new Vector3(0, -90, 0), turnSpeed);

Don’t use Vector3.Lerp on rotations. Rotations in Unity are handled as Quaternions so use that. For interpolating your rotation call Quaternion.Slerp(). Here some example code:

var rot = Quaternion.Euler( 0,-90,0 );
transform.rotation = Quaternion.Slerp( transform.rotation, rot, Time.deltaTime );

Good luck!
