Description
|
Checks whether the vision sensor detects the indicated entity. This is the extended functionality version of sim.checkVisionSensor. Detection is silent (no visual feedback) compared to sim.handleVisionSensor. The vision callback functions will be called on the acquired image. Also, the renderable flag of the entity is overridden if the entity is an object. See also sim.readVisionSensor.

C synopsis
|
simFloat* simCheckVisionSensorEx(simInt sensorHandle,simInt entityHandle,simBool returnImage)
|
C parameters |
sensorHandle: handle of the vision sensor object
entityHandle: handle of entity to detect (object or collection), or sim_handle_all to detect all detectable objects
returnImage: specifies what should be returned. If true, the sensor's image buffer is returned, otherwise its depth buffer is returned
|
C return value

|
Lua synopsis
|
table buffer=sim.checkVisionSensorEx(number sensorHandle,number entityHandle,boolean returnImage)
string buffer=sim.checkVisionSensorEx(number sensorHandle,number entityHandle,boolean returnImage)
|
Lua parameters |
sensorHandle: handle of the vision sensor object. Can be combined with sim.handleflag_codedstring if you wish to retrieve the image or depth map coded in a string (much faster).
entityHandle: Same as C-function
returnImage: Same as C-function
|
Lua return values
|
Similar to C-function: a table containing the image or depth buffer is returned (or nil in case of an error)
