NetDuke32

About

NetDuke32 is a multiplayer-centric port based on EDuke32. Started late 2015 as a series of maintenance builds of EDuke32-OldMP, it has since branched out and evolved. NetDuke32 brings new features, QoL (Quality of Life) and netcode improvements, and tries to improve the overall multiplayer experience.

Features

(Page is a work in progress)

Documentation

NetDuke32 has a few exclusive DEF tokens, GameVars, and structure members to access a few of its features. They will be listed here.

NOTE: Since NetDuke32 is still very much an early work in progress, these may be subject to changes, deprecation, or outright removal.

DEF Tokens

• addplayercolor <palnum> <name> - Adds a palswap to the list of selectable player colors for multiplayer.

Example: addplayercolor 17 "Green (Blue Skin)"

• delplayercolor <palnum> - Deletes a palswap from the list of selectable player colors for multiplayer. A value of -1 deletes them all. (Make sure to define your own after!)

Example: delplayercolor 23 (Which would make "Yellow" un-selectable.)

GameVars

• predicting (Read-only) - Returns the processing state of NetDuke32's prediction system. Useful to prevent desynchronization or visual artifacts in certain scenarios; For example, trying to call spawn in player code that is normally predicted would result in a de-sync, but guarding it with ifvare predicting 0 will make sure it only happens during the canonical gamestate, preserving synchronization.

Values:

0 = Currently processing canonical gamestate.

1 = Currently predicting upcoming gamestate.

2 = Making corrections to any mispredictions.

• numteams (Read-only) - Returns the number of currently defined teams for TDM.

Example: whilevarvarl TEMP numteams { addvar TEMP 1 } (Will loop while TEMP is less than numteams. Useful for things like displaying information for all teams, or setting an attribute for all.)

• DMFLAGS - Gets or sets the current DMFlags. See UserDefs section for a list of flags.

Examples:

ifvarand DMFLAGS 4 { spawn LIZTROOP } (Will spawn a LIZTROOP if DMFLAG_RESPAWNMONSTERS is enabled.)

orvar DMFLAGS 256 (Will enable DMFLAG_NOPLAYERID)

Structure Members

UserDefs (get/setuserdef[].)

• teampal <teamnum> - Team's palette number.

Example: getuserdef[].teampal 2 TEMP // Gets team's palswap.

• teamfrags <teamnum> - Team's frag count.

Example: getuserdef[].teampal 2 TEMP // Gets team's frag count.

• teamsuicides <teamnum> - Team's number of suicides.

Example: setuserdef[].teamsuicides 2 0 // Sets team's suicides to 0.

• dmflags - A bitfield containing a series of gameplay-affecting flags, such as friendly fire, respawning items, whether or not FOV changes are allowed, etc.

Flags:

DMFLAG_FRIENDLYFIRE = 1

DMFLAG_NOMONSTERS = 2

DMFLAG_RESPAWNMONSTERS = 4

DMFLAG_RESPAWNITEMS = 8

DMFLAG_RESPAWNINVENTORY = 16

DMFLAG_MARKERS = 32

DMFLAG_NOEXITS = 64

DMFLAG_WEAPONSTAY = 128

DMFLAG_NOPLAYERID = 256

DMFLAG_NOFOVCHANGE = 512

DMFLAG_ALLOWVISIBILITYCHANGE = 1024

• m_dmflags - Same as above, but contains the flags selected in the menu, before being confirmed and transferred to dmflags when starting a new map.
