(A3 1.24) Generally speaking setVelocityTransformation is more likely a combination of setPosASL, setVectorDirAndUp (or BIS_fnc_setPitchBank) and time multiplier. It can be used as a position tracker with all necessary information collected, copied and then released within one function. Here’s a simple reproduction on how setVelocityTransformation works in game: private ["_dataOld","_dataNext","_capturedData","_obj","_fps","_startTrackingTime","_stepOld","_stepNext","_tracker","_tempTime"]; _stepOld = 0; _tempTime = 0; _stepNext = 1; while {true} do { _capturedData = _capturedData + [[ getPosASL _obj,velocity _obj,vectorDir _obj,vectorUp _obj]]; sleep _fps; _tempTime = _tempTime + _fps; if (_tempTime >= _startTrackingTime) then { _dataOld = _capturedData select _stepOld; _dataNext = _capturedData select _stepNext; _stepOld = _stepOld + 1; _stepNext = if (_stepNext >= (count _capturedData)) then [{_stepOld},{_stepNext + 1}]; _tracker setVelocityTransformation [_dataOld select 0,_dataNext select 0,_dataOld select 1,_dataNext select 1, _dataOld select 2,_dataNext select 2,_dataOld select 3,_dataNext select 3,1]; }; }; Tracker starts coping the route and stance from the object when time start counting. TimeDiff determines the distance multiply between the current position and the next position.
