Collision Detector Template component
Polls a chosen panel object to see if it has collided with another object. When collisions happen, a user notification event is generated and a pin is set or reset. Another event is sent when the two objects separate.

|
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 |
| The pin that should change state when objects collide or separate. | |
|
Polarity |
| Active High = Pin is high when objects collide, low when they are separate. Active Low = Pin is low when objects collide, high when they are separate. | |
|
|
Simulation |
|
Test Object |
| The object to test for collisions. A user event is sent each time this object collides with any other, or when the two object separate. | |
|
|
Mouse Object |
| Choose an object that the user can clock on to simulate a collision when testing. | |
|
Detector Ident |
| An ID value to identify this particular detector. Will be sent as the 'Ident' value for the notification events sent out so that multiple detectors can be told apart. | |
|
|
Timer Interval (ms) |
| Time in milliseconds between collision scans. Small time = Greater CPU load Large time = More like to miss brief collisions. | |
