You have to use Mathf.Clamp to do this. Below is what I use to rotate the camera up/down and left/right. You can modify the yMaxLimit and yMinLimit variables to the angles you want to limit it to. There should be no limit while moving in the x direction. public float xMoveThreshold = 1000.0f; public float … Read more
