A map must be specified.Ī person joining a game does not need to specify any additional parameters aside from loading any custom WADs or DeHackEd patches that the host is using. The game will therefore start immediately with all multiplayer rules with just one player.

The fourth one starts a solo multiplayer game on map29.

The third one joins a server hosting any kind of game, at the specified IP address, and on default port 5029.

The second one also hosts two, but uses the default skill level (Hurt Me Plenty), and sets the game mode to deathmatch.

The first command line tells the computer to host two nodes (itself and one other), warp immediately to MAP01, and set the skill level to Ultra-Violence.

A sample set of command lines follows:įor more commands, see Command line parameters and CVars. Multiplayer games must be started either from the command line or from a launcher of some sort. Map 'scale' (enemy count, complexity, etc) also has no affect on bandwidth, due to netgames in ZDoom only needing to send player control data. ZDoom's advantage, however, is its low bandwidth usage (averaging 300 bytes per second per node) and lack of the 'host-advantage' phenomena (the networking is lock-step).

The game state is tracked on a peer-to-peer system, unlike the csDoom derivatives or Zandronum, which are much better suited to larger-scale games because of their focus on client-server architecture.
