Component: Beam Breaker (Light): Difference between revisions

Revision as of 14:20, 13 July 2026

Automatically sets and resets a pin depending on whether a panel object breaks the 'light beam'. Can also send simulation notification events.

No additional examples

	ReadState
Get the current collision state. The 'Polarity' property will affect whether a collision is represented by a high or low state.
- BYTE	Return

	SetTarget
Set the object that you want to test for collision with. If this is not called, or is called with handle = 0, collisions will be tested against every panel object that has 'Solid' status. NB) Specifying an object will save CPU power!!
- HANDLE	Target
The object to test for collision with.
- VOID	Return

	WaitUntilHigh
Pause the program until the detector goes high. 'Polarity' will affect whether high value represents a collision or separation. NB) In simulation, only use this macro if testing for collision with animated or timer driven objects!!
- VOID	Return

	WaitUntilLow
Pause the program until the detector goes low. 'Polarity' will affect whether low value represents a collision or separation. NB) In simulation, only use this macro if testing for collision with animated or timer driven objects!!
- VOID	Return

	Properties
	Connections
	Pin
Chip pin that the beam breaker is connected to,.
	Polarity
Active High = Pin is on when beam is broken, off when beam is intact. Active Low = Pin is off when beam is broken, on when beam is intact.
	Simulation
	Target
Choose a specific object to test for breaking the beam. If none is chosen, will check against any other object with 'Solid' status - note, checking all objects increases the CPU load!!
	Range
Set the distance between the transmitter and receiver
	Show Beam
Shows the 'light beam' on screen - arrow points from transmitter to receiver.
	Timer Interval (ms)
Time in milliseconds between collision scans. Small time = Greater CPU load Large time = More like to miss brief collisions.
	Notification
	Notify
Whether or not to notify the component parent of any changes. Data will be zero or one (the current pin value).
