Example: To set up the Position controllers of a camera for moving with a
joystick:
The rotation of the camera about its world Z axis will be controlled by the X
motion of the joystick. You'll set up the Position controllers of the camera to
move the camera forward and back with the Y motion of the joystick.
1 Assign a Position Motion Capture controller to the camera's Position
track, and access its Properties dialog.
2 Assign a Joystick Input Device to both the X Position and Y Position
buttons.
3 Click the Edit Binding X button, and then choose the Y option under
Joystick Axis.
4 Check Accumulate.
5 Click the Edit Binding Y button, and also choose Y under Joystick Axis.
6 Check Accumulate.
The Y motion of the joystick will now affect both the X and Y positions
of the camera.
Example continued: To add the increment based on direction options:
If you tested the camera motion at this point, moving the joystick forward or
backward along the Y would produce a diagonal motion because the Position
tracks would receive equal amounts of X and Y values. Adding the Increment
Based On Direction options will change this.
1 Click the X Edit Binding button.
2 Under Increment Based On Direction, click the button beside Controller.
A dialog appears with a list of controllers.
3 Find and select the Rotation Motion Capture controller for the camera.
4 Set the Direction option to Z (the local axis along which the direction
points).
5 Set the Component option to X (matching the Edit Binding button).
6 Click the Y Edit Binding button.
7 Click the button beside Controller, and assign the Rotation Motion
Capture controller.
8 Set the Direction option to Z, then set the Component option to Y.
