Control mappings

Control	Mappings
Button 1	When orbiting, zooms in. (Press and hold to keep zooming in.) When walking, raises camera as if you are raising your head.
Button 2	When orbiting, zooms out. (Press and hold to keep zooming out.) When walking, lowers camera as if you are kneeling.
Button 3	Toggles between presentation and authoring.
Button 4	Toggles between orbiting and walking.
Button 5 (at back)	Tilts the camera. Hold this button down with one hand and use the Right stick with the other hand to change the setting. Press this button again to return to the upright camera position.
Button 6 (at back)	Changes the point of interest. Hold this button down with one hand and use the Left stick with the other hand to change the setting.
Button 7 (at back)	Decreases navigation speed. Press repeatedly to keep decreasing speed. (The speed appears on the screen when walking.)
Button 8 (at back)	Increases navigation speed. Press repeatedly to keep increasing speed.
Home	Goes to home (default) view.
Mode button	Switches the D-pad and left stick controls (that is, choose which control invokes numbered shots and which one drives).
D-Pads	By default, invokes hotkeys 1 through 8, set up by the user to go to particular shots. Press the upper part of the D-pad for hotkey 1, up and to the right for hotkey 2, and so on in a clockwise direction around the keypad. (To swap this behavior for that of the left stick, press the Mode button.)
Left stick (tracking)	When orbiting, tracks the camera up, down, left and right. When walking, tracks the camera in, out, left and right. (To swap this behavior with that of the right stick, press the Mode button.)
Right stick (rotating)	When orbiting, rotates the camera around the centre of interest (and keeps focus on it). When walking, rotates the camera but keeps it in one location (as if you are turning your head to look around.) (To swap this behavior with that of the left stick, press the Mode button.)

User variables

The following user variables are available for you to change the behavior of the game controller.

SHOWCASE_SWAP_STICKS: When set to 1, swaps the behavior of the left stick and right stick as described above.
SHOWCASE_SWAP_DOLLY_AND_TRACK_UP_DOWN: When set to 1, changes the behavior so that moving the left stick up and down zooms in and out (rather than tracks). Buttons 1 and 2 then track up and down (rather than zoom). Moving the left stick left and right continues to track left and right.
SHOWCASE_SWAP_LOOK_UP_DOWN: When set to 1, inverts the movement of the track stick (by default, the left stick) so that up goes down and down goes up.

Right-mouse click over the My Computer icon on your desktop.
The System Properties window appears.

To add user variables, click the New button (below the upper user variable pane).
To change the value of user variables, click the Edit button (below the upper user variable pane).
A value of 1 means the user variable is turned on. A value of 0 means it is turned off.
