Jazz Jackrabbit 2 Online

An updated version of survivor.mut, now compatible with every Ground Force level ever made that I could find1. This mutator provides the same smooth, worry-free hosting/playing experience for all Ground Force levels as before, to wit:

• No need to hit trigger crates or kick clients for hitting them too soon; instead, each level will start automatically once all players are done connecting/downloading.
• JJ2+‘s LRS code means cycling is automated too, with no bother about picking up gems and finding an End Area. Also playable in TLRS or XLRS.
• Multiple lives per player are supported through the standard /maxlives command.
• Despite the game not being hosted in Treasure Hunt, the old behaviors of not being able to interact with springs or pinball objects while blinking are maintained.
• Players who lose are Out, allowing them to spectate without needing to manually unspectate for the next level.
• In XLRS or during overtime, players can hurt and roast each other.
• While waiting to begin, players get to watch a preview of the arena.
• Jazz and Lori are playable, but are made to share Spaz’s double jump.
• If the game is paused (/stop) partway through, tiles and trigger crates will not be destructible until the game is resumed again.

To host a specific Ground Force level, the host will need both this mutator and the .gf file corresponding to that level, e.g. mingfpack1.gf for mingfpack1.j2l.

If you attempt to use this mutator for a level that does not have a corresponding .gf file, e.g. if you are creating your own new Ground Force level and want it to be compatible with gfv.mut, then you will be shown a graphical user interface for defining all the relevant properties of your level: e.g. where the arena is, what causes players to die, what ammo they should start out with, whether they should morph into frogs or something, and several other optional features. Additional documentation for each section of this process will be written to the chatlog for you to consult as you go along. (Due to JJ2+‘s limitations, the resulting file will be saved with the extension .gf.asdat instead of simply .gf, and you can rename it to .gf if you want but the mutator will accept it either way.)

While you are busy developing a new Ground Force level, try hosting it in a networked/TCP/LAN server instead of an Internet server. This will allow you to enter the arena even during the Pregame. Otherwise it is impossible to test levels without two or more players in the server, because JJ2+ will never allow the game to start with only one player.

1: plusgf and plussurvivor could not be included because they rely on spectator mode in a way that is incompatible with this mutator
