TFormVector
Parameters:
| x# - x axis rotation on which to perform transformation y# - y axis rotation on which to perform transformaion z# - z axis rotation on which to perform transformation src_entity - source entity space from which to transform co-ordinates dest_entity - destination entity space to transform co-ordinates |
Description:
| TFormVector takes the source and destination entities (taking x, y and z as offset angles, usually all set to the source entity's orientation, ie. EntityPitch (src), EntityYaw (src) and EntityRoll (src)), and performs a transformation to determine the difference in orientation between source and destination entities.
The resulting offset angles for each axis can be retrieved by the use of the TFormedX, TFormedY and TFormedZ functions. |
