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.

SENSORS
Detailed description
No detailed description exists yet for this component
Examples
Simple example showing the collision detector component at work, when a collision is detected the direction of the motor is reversed.
Detector
Simple example showing the beam break detector component at work, when a collision is detected the direction of the bouncing ball is reversed.
Beam Break Demo
Downloadable macro reference
|
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). | |
