If you are asking where to assign a script to the uid or aid it depends on what you want to do.. if you want to use an object and have somthing happen it is an action, if you want to move it and have monsters spawn its a movement etc Generally though this can all be set in the movements.xml or actions.xmli have a dumb noob question...I see how to change priorities in the map editor to give it the uniqueid but where in the files do you change or add a uniqueid??
