It's been a while since I've actually used the script (enjoying a stint as a player for a change!) but I believe you select your trap, run the setup macro (!ItsATrap_trapCreationWizard_showMenu) and then you can use the line tool to draw a path, select that then use the 'Set Trigger' option and then (with the line you drew selected) choose the 'set selected paths' to set the path as a trigger, you can add others by doing the same thing and choosing 'add selected path' to have more than one trigger (I think). Once you've got a trap setup fully you can look at the token's gmnotes to see how the menu creates the json the trap uses, master that and you can avoid using the menu and edit trap settings at source (paths require the id of the trigger). I recommend having a test game to play around with it, just make sure you have the player ribbon on the testing page otherwise nothing will work ;)
