MouseTrap illustrates some of Ucigame's mouse handling features,
using onMouseXXX() methods and the mouse object.
Left and right clicks rotate the mouse (more if Ctrl or Alt buttons are down). The mouse wheel moves the mouse up and down. The mouse can be dragged (x and y are swapped if the right button is held down). |
