I've documented the plug-in fully on GitHub, so if you'd like to make your own map with DMZ objects read the documentation!!!! WARNING !!!
The BZFlag 2.4.x protocol does not correctly support change shot types through a plug-in. A shot type can be changed by a plug-in and other players on the server will see that new shot type. However, the tank who made the shot will not see the change; this means that if the shot ricochets off any objects, the shot path the player sees is entirely different from the shot path other players on the server will see.
This plug-in converts shots into Phantom Zoned shots, rendering them harmless to most tanks. Despite the name, these shots can and will kill any phantomed tanks.
Use at your own risk!
All development for this plug-in occurs on GitHub, so be sure to follow development and new releases there; I will very rarely update this post with updates on new releases. The link below will always point to the latest stable release.
