Sensor again

Hi,I want to remove the Sensor，beause I want this to be executed once,I use this methods:

Code:


mySIO2sensorcollision(void *_ptr)
{
    SIO2sensor *_SIO2sensor = ( SIO2sensor * )sio2ResourceGet( sio2->_SIO2resource,
                                    SIO2_SENSOR,
                                    "colide" );
  _SIO2sensor = sio2SensorFree( _SIO2sensor );
}
init()
{
    SIO2object *player = sio2ResourceGetObject( sio2->_SIO2resource, "object/player" );
    SIO2object *target = sio2ResourceGetObject( sio2->_SIO2resource, "object/target" );
    sio2SensorInitCollision("colide", player, target, mySIO2sensorcollision);
}



but breakpoint at sio2PhysicCollisionCallback() funtion;
-> [ if( _SIO2sensor->_SIO2sensorcollision )] ///breakpoint

the _SIO2sensor is not NULL.



why? please help me,thank you very much,how to del. sensor?

Don't delete sensor inside their callback function... just mark them and remove them inside your rendering loop.

thank you!Is my own wrong，thank you again!
