Just invert the scale
-property of your Player
-node.
The default is (1, 1). If you set it to (-1, 1) you will flip it horizontally. If you set it to (1, -1) you will flip it vertically. Note that this is different from flipping a sprite, where just the texture is flipped, not the node itself! So no, even if the Hitbox
-node would be a child of your Sprite
-node, setting the flip_h
-property wouldn't flip the hitbox.
Btw: A "Hotbox" is something very different. ;) Sorry, could not resist.
