simReadProximitySensor / sim.readProximitySensor
Description
|
Reads the state of a proximity sensor. This function doesn't perform detection, it merely reads the result from a previous call to sim.handleProximitySensor (sim.handleProximitySensor is called in the default main script). See also sim.checkProximitySensor, sim.checkProximitySensorEx and sim.resetProximitySensor.

C synopsis
|
simInt simReadProximitySensor(simInt sensorHandle,simFloat* detectedPoint,simInt* detectedObjectHandle,simFloat* detectedSurfaceNormalVector)
|
C parameters |
sensorHandle: handle of a proximity sensor object
detectedPoint: coordinates of the closest detected point (x, y and z: detectedPoint[0]-detectedPoint[2]) relative to the sensor reference frame, and distance to the detected point (1 value: detectedPoint[3]). Can be NULL
detectedObjectHandle: handle of the object that was detected. Can be NULL
detectedSurfaceNormalVector: normal vector (normalized) of the detected surface. Relative to the sensor reference frame. Can be NULL

Lua return values
|
distance: distance to the detected point if result is 1, nil otherwise
detectedPoint: table of 3 numbers indicating the relative coordinates of the detected point if result is 1, nil otherwise
detectedObjectHandle: handle of the object that was detected if result is 1, nil otherwise
detectedSurfaceNormalVector: normal vector (normalized) of the detected surface. Relative to the sensor reference frame. Is nil if result is different from 1
