 The snapping tool makes use of a unit for highlighting the nearest buildable cell, so it's a cpack instead of a script : [[https://knucklecracker.com/wiki/doku.php?id=cw4:cpack:docs:e58ef3f2-1468-42fa-ac84-c3561ddd9452|Kalli - SnappingTool]]

+===== Make Units Unselectable =====
+You can make friendly/enemy/all units (un)selectable and/or (un)destroyable with this script.
+The $ variables are now set so that friendly (=human) units are set unselectable and undestroyable, so that it's ready to use in a pac map. The variables are either 0 or 1.
+Enemy (=creeper) units are always undestroyable. Changing this setting with 4rpl does nothing, but also doesn't break anything.
+The script can be used from the console, or be added as a global script to a cpack. If used as a global script, then the script must run while paused. It will only apply to units that exist at map start.
