Sprite:GetAngle() always returns 0

[thehankinator]

Calling GetAngle() on a sprite set to Billboard mode is always returning 0. Here is how I set it up:

1) Create a sprite

2) Set it to Billboard mode

3) Assign a material

4) Put this script on it

function Script:UpdateWorld()
	System:Print(self.entity:GetAngle())
end

The billboard appears to be working (always facing the camera) but the script always prints 0. I tried casting it to a sprite ( tolua.cast(self.entity,"Sprite") ) and calling GetAngle on that but no change. Any idea what I am doing wrong?

The GetAngle() returns the rotation of the 2D plane set from SetAngle() apparently. If you rotate your sprite with SetAngle(), it doesn't change the angle of a sprite in billboard mode in reference to the camera - it changes the rotation of the 2D plane around its center.

And it appears that the sprites' rotation in relation to the camera does not have anything to do with the sprite's 3D rotation - I assume since its probably a shader controlling the rotation?

That makes sense, Thanks!
