Vector3.Angle()
Hi,
I'm trying to get the angle like below.
But in 3D space not on the same level, I thought this would do it.
function angleToPlayer() : float
{
targetDir = player.position - transform.position;
forwardVector = transform.forward;
angle = Vector3.Angle(forwardVector, targetDir);
return angle;
}
But unless the enemy is looking down or up, directly at the player the angle is way to high, whats missing?
EDIT .. The below angle from the dragon to the green marker on the deck shows 36.62242
The problem (a very annoying one, I might add!) is that Vector3.Angle takes into account ALL rotation axes, not just the y axis. That's why you get those high angle values unless looking directly at the target. There are basically two workarounds: a) Make sure both positions are on the same y position b) Use an object taht only rotates around the y axis: for example, a Character Controller that only rotates left and right, and where the camera is a child of it and only the camera rotates up and down (head rotation).
