Beam Breaker component

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

Macro reference

ReadState

Fc9-comp-macro.png ReadState
Get the current collision state. The 'Polarity' property will affect whether a collision is represented by a high or low state. 
Fc9-u8-icon.png - BYTE Return


SetTarget

Fc9-comp-macro.png 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!! 
Fc9-h32-icon.png - HANDLE Target
The object to test for collision with. 
Fc9-void-icon.png - VOID Return


WaitUntilHigh

Fc9-comp-macro.png 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!! 
Fc9-void-icon.png - VOID Return


WaitUntilLow

Fc9-comp-macro.png 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!! 
Fc9-void-icon.png - VOID Return


Property reference

Fc9-prop-icon.png Properties
Fc9-conn-icon.png Connections
Fc9-type-5-icon.png Pin
Chip pin that the beam breaker is connected to,. 
Fc9-type-16-icon.png 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. 
Fc9-conn-icon.png Simulation
Fc9-type-17-icon.png 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!! 
Fc9-type-15-icon.png Range
Set the distance between the transmitter and receiver 
Fc9-type-7-icon.png Show Beam
Shows the 'light beam' on screen - arrow points from transmitter to receiver. 
Fc9-type-21-icon.png Timer Interval (ms)
Time in milliseconds between collision scans. Small time = Greater CPU load Large time = More like to miss brief collisions. 
Fc9-conn-icon.png Notification
Fc9-type-7-icon.png Notify
Whether or not to notify the component parent of any changes. Data will be zero or one (the current pin value).
