Moving an object relative to itself is something that I used to find really handy when using TGF/MMF. A similar function would be cool in construct, unless there is already one and I haven't found it <img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" />
By moving an object relative to itself I mean, for example, a character always looks at the mouse, pressing A would make it strafe to it's left regardless of what direction it's facing.
