Operands

Each operand is evaluated as part of an expression. Most operands have specific target types, similar to actions, since they evaluate to the current value of a specific property of the target. For example, the kOperandQTVRPanAngle returns the current pan angle of the operand's target QuickTime VR track.

Other operands, such as kOperandKeyIsDown and kOperandMouseLocalHLoc , allow for a polling form of input by determining the current state of the keyboard or the location of the mouse.

Constants may be specified using the kOperandConstant operand.

The kOperandExpression allows for expressions to be nested within other expressions.
