Rotate Around Local Y Axis
How does the unity rotate tool rotate around the local y axis? It seems that if I try to adjust localEulerAngles.y programmatically, we do not get the same effect. When rotating with the local rotate tool, x, y and z values are changed.
How can we rotate a transform around its local y axis?
Say you wanted a Transform to Look (or point) towards a vector, while being constrained by the local y axis. How can that be achieved?
transform.RotateAround(transform.position, transform.up, Time.deltaTime * 90f);
transform.up would be the local axis Y positive axis (depending on whatever object the script is attached to). It would not actually be world axis up.
Typically, you need to turn something that already has a direction by some angle. Having the angle calculated from time is only useful for simple animations, nothing else.
Just wanted to say that this is useless if you need to set absolute rotation and not incremental, which is a rare occurrence as i can see.
If you need to set absolute rotation, transform.rotation = originalRotation * Quaternion.Euler(desiredChangeInRotationX, desiredChangeInRotationY, desiredChangeInRotationZ);
the space parameter is what you need:
transform.Rotate(0, yAmount, 0, Space.Self);
if i want to rotate the object along with mouse drag in complete 360' in clock and anti clock also
Try this:
void Update()
{
transformRotateAround(transform.position, TransformDirection(Vector3.up), Time.deltaTime * 90f);
}
private void Update() { transform.Rotate(0, 0, 10 * Time.deltaTime); }
Thank you for your code! It works beautifully. Very simple and easy to understand!
