I rename "On hit target position" to "Condition:On reach target position", the behavior are equal. Sorry for confusing, I will change it back.
rex_moveTo vs rex_platform_moveTo
rex_moveTo will move sprite straightforward.
rex_platform_moveTo drives a sprite which has official platformer behavior to "move left" or "move right", i.e. it is an addon of official platformer behavior.
