I know how to remove items already present on the map (via scripting), but how do you remove items generated by scenery (IE the watchers arm on 'shadow of the mountain' is generated when the arm box is detroyed but the arm box is scenery).
Thanks for the help.
PS. So far I have a geometry filter to check to see if the arm is present on the map, and just don't know what to do with the results.
Try using that GEOM to filter the projectile into a CTRL that gives it to an invisible unit. You will probably need to assign the Tested Items Inside Field Name to be "proj"
