A locked door, secured by a 3-digit hexidecimal combination lock. The digits are individually triggered by the player (using a gun sight helps!). The combination is preset to 3-2-1 in the zipped map, but can be set from 0-0-0 to F-F-F by customizing the multi_manager that is paired with the trigger_auto in front of the door.

This "lock_set" multi_manager is automatically triggered to set bits that are not wanted in the final combination. These bits are "lock_b0" thru "lock_b11", the three rows of tiny 2x2 doors that are hidden within the wall, between the large door and combination display. To set the combination to F-0-3, for example, edit "lock_set" so that it fires bits 2,3,4,5,6, and 7. Firing all of the bits (combo 0-0-0) is not recommended - this will immediately open the door, since the displayed digits are preset to 0-0-0!

All of the interacting entity names are prefixed by "lock_", so for quick change of property names/values in multiple placements of this prefab, use search-and-replace in you favorite text editor on the map file.
