Motion Helper component

Helper for building components which require simulation of constant motion. Linked objects can be issued speed and acceleration parameters, and will then be animated automatically until another command is issued. The helper can control motion for up to four objects simultaneously, all with their own discrete motion settings.

Macro reference

	RegisterTarget
Add a new object to the list of objects which the motion helper is animating. Up to four objects can be animated by each Motion Helper.
- HANDLE	Target
Handle of the target to link to.
- HANDLE	AxisObject
Axis object for this definition
- BYTE	Axis
Axis to move along/around (0=X, 1=Y, 2=Z)
- BYTE	Type
Motion type (0=Rotary, 1=Linear)
- VOID	Return

	SetAcceleration
Sets the acceleration for the target object. This sets how quickly the object reaches its new speed following a call to SetSpeed. NB) The object must be one of those registered using RegisterTarget.
- HANDLE	Target
Handle of the object to set the acceleration for.
- FLOAT	Acceleration
Time in milliseconds to reach a new speed.
- VOID	Return

	SetSpeed
Set a new target speed for this object. Will use the acceleration parameter to set how long it will take to reach the new speed. NB) The object must be one of those previously declared using RegisterTarget
- HANDLE	Target
Target object to set the speed for.
- FLOAT	Speed
Target speed. World units per second or degrees per second.
- VOID	Return

	UnregisterTarget
Remove a target from the list of links.
- HANDLE	Target
Handle of the object to remove
- VOID	Return

	UnregisterAll
Totally clear the list of registered objects
- VOID	Return

Property reference

	Properties
	Frame Interval
Time interval between animation frames. Does not affect the speed of motion, only the rate of screen updates.
	On Stop
Decide what action to take when simulation stops. No Action - Animation is paused, continues from this position when simulation restarts Return to start - all object returned to their start positions, current speed resumes on simulation start. Clear speeds - objects retain their position, but speed is set to zero. Return and clear - objects return to start position and have theri speed set to zero.
