Using the fire buttons on the Zoomer.
Q. How can I use the Zoomer's fire buttons (and presumably the joystick button) in my application? A. Look at section "Controls" in the Zoomer portion of the documentation. It includes the following: Input from the buttons acts as "keyboard" input, using a custom set of "keys." These keyboard input events will have a character whose top byte has the value CS_CONTROL and whose bottom byte has one of the following VChar ( "virtual character" ) values: VC_JOYSTICK_135 VC_JOYSTICK_90 VC_JOYSTICK_45 VC_JOYSTICK_180 _______________ VC_JOYSTICK_0 VC_JOYSTICK_225 VC_JOYSTICK_270 VC_JOYSTICK_315 VC_FIRE_BUTTON_1 VC_FIRE_BUTTON_2 The VC_JOYSTICK values correspond to the Zoomer directional keys. Note that the Zoomer has just four directional buttons-the 45, 135, 225, and 315 degree values will be passed when the user is pressing two buttons at once. The VC_FIRE_BUTTON values correspond to the two zoomer fire buttons.
