ADOBE DIRECTOR BASICS
3D: Controlling action
In the test above, notice how the linearVelocity and linearMomentum indicate that the centerOfMass is moving
at a constant rate along the zAxis. However, the position of the rigidBody oscillates on the xAxis as the block rotates
around its centerOfMass.
Try dragging the pinhead to change the orientation axis, and dragging the position and orientation angle sliders to see
how this affects the block.
Note: When the orientation angle is zero or 360°, the orientation axis will automatically be set to vector(1, 0,
0). If you want to rotate a rigidBody around a different axis, be sure that you set both the axis and the angle each time.
The orientation axis is automatically set to vector(1, 0, 0) for angles of 0 and 360
For a comparison of rigidBody.attemptMoveTo() and setting the rigidBody.position property, see “Rigid body
methods” on page 316.
Note: Notice how the orientation angle moves backwards and forwards between 0 and 360 and that the orientation axis
flips through 180° each time the angle reaches 0 or 360.
Static properties
A rigidBody created with a body type of #static will never move as the result of a collision. You can stop a #dynamic
rigidBody from moving in two different ways.
rigidBody.isPinned can be TRUE or FALSE. If you set it to TRUE, then a dynamic rigidBody will behave like a static
one. If it is struck by a moving dynamic rigidBody, it will remain pinned to its current position.
