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
|
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
|
|
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
|
|
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
|
|
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 |
Property reference
|
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). | |
