[Solved] Rotation towards mouse is wonky.

Newbie & Debugging Questions
#1 
// Point to mouse
		float dX = Gdx.input.getX() - position.x;
		float dY = Gdx.input.getY() - position.y;
		direction = (float) Math.atan2(dY, dX);
		direction = (float) Math.toDegrees(direction);

How do I fix my math?

#2

You just gave us code. What does the output look like?

Mouse is at the top left the darker more shadow-y part at the bottom right is where it should be pointing. This isnt a constant pattern though, as move it to a different location provides a different pattern result.

#4

Moving my mouse on the x-axis from left to right gives this result. This is dragging it above the object

Try flipping the y:


float dY = position.y - Gdx.input.getY();
#6

Figured out the problem, had to unproject my mouse coordinates. Thanks for the help!


	// Point to mouse
		mousePos.x = Gdx.input.getX();
		mousePos.y = Gdx.input.getY();
		camera.unproject(mousePos);
		float dX = mousePos.x - position.x;
		float dY = mousePos.y - position.y;
		direction = (float) Math.atan2(dY, dX);
		direction = (float) Math.toDegrees(direction);
		System.out.println(direction);
