#DarkMultiPlayer ${PROGRAMVERSION}

DarkMultiPlayer is a multiplayer mod for KSP 1.0.4. It supports subspace-style (and master controlled warp) warping & career mode, with an easy-to-edit server database.

The DarkMultiPlayer server and client is cross platform, it runs under mono on linux and mac.

##Client

###Installation / Updating Option a) Extract the DarkMultiPlayer zip to GameData.
Option b) Download DMPUpdater from http://godarklight.info.tm/dmp/downloads/dmpupdater/, place the program next to KSP.exe (Or KSP.app/KSP.x86_64), and run it.

###Connecting to a server The connection window will appear on the main menu. Type in a username, press add server, type in the details, and then hit add.
A player keypair will be generated (At GameData/DarkMultiPlayer/Plugins/Data/private.txt) during the first DMP start. DMP registers your username to the server with this keypair. If you lose your keypair, you will no longer be able to connect to the server with that username until the server administrator deletes you from Universe/Players/.

###Connecting, If you are also running a server If you are running the server locally, you will want to connect to 127.0.0.1/localhost.
If you are running the server on a networked computer, you will most likely be connecting to a 10.x.x.x or 192.168.x.x address.
Do not type in your public IP, this usually refers to your modem, which won't be running the DMP server (Unless you have the public IP address in your computer, which is rare).

###Flag sharing DMP will sync any flags under the GameData/DarkMultiPlayer/Flags folder - Put your local flags in here if you want other players to see them. All other flags will work in any location if all players have the flags installed, but it will get reset to default if a player gets near a vessel with a flag they do not have.

###Chat window By default, you will join the Global channel (and cannot leave it).
To PM a player, type /query playername or click on their player name in the global chat.
To start a group chat, type /join groupname.
To leave a PM or group chat, type /part or /leave in the window you want to leave. You can also press the 'Leave' button.
Group chats are indicated by the '#' mark, player chats are indicated by the '@' mark.
Newlines can be entered in the chat window with shift+enter.

###Craft sharing window To upload a craft, press on your user name and then click 'Upload'.
To download a craft, press on the owning player's username and select one of their uploaded vessels.

###Screenshot sharing window To upload a screenshot, press 'Upload'.
To view a players screenshot, press on their player name.
If the server has screenshot saving enabled, The players name will go red when there is a new screenshot to view.

###Mods If you try to connect to a modded server, DMP will tell you everything you are missing, and tell you everything you shouldn't have in order to connect. If there is any DLL's that need to be added, you will need to restart KSP.

###Warping Both regular and physics warp are available. When you warp, you will be put into your own "time" (called a subspace) which other players can sync to. All updates from the past affect future players, but future players will not affect players in the past.

###Options The file is located at DMPServerSettings.txt next to DMPServer.exe. You will need to edit this file while the server is off-line. The file is created on the first server start.

###address address - The address the server listens on.
WARNING: You do not need to change this unless you are running 2 servers on the same port.
Changing this setting from 0.0.0.0 will only give you trouble if you aren't running multiple servers.

####port The port to listen on, default 6702.

####warpmode The warp type.

• Mode 0: MCW_FORCE, You take a warp lock, every player will follow you into warp, and you will create a subspace when you come out of warp that everyone will sync to.
• Mode 1: MCW_VOTE: Same as MCW_FORCE, but you have to vote first - This option may be good for players doing the same thing with voice chat.
• Mode 2: MCW_LOWEST: NOT IMPLEMENTED - Warps to the lowest common warp factor.
• Mode 3: SUBSPACE_SIMPLE: NOT IMPLEMENTED - Allows you to create a subspace in the future, but you can only sync to the latest player with the '>' key.
• Mode 4: SUBSPACE: The default, and most important mode. Each player can warp at will, and they can "sync" to other players times. This is the only mode that allows QuickSaving/QuickLoading
• Mode 5: NONE: Players will be unable to warp.

####gamemode

• Mode 0: SANDBOX - The default sandbox game mode.
• Mode 1: SCIENCE - Everyone has their own science points. Shared science is currently not implemented.
• Mode 2: CAREER - Everyone has their own career mode points and funds. Shared science is currently not implemented.

####gamedifficulty - Specify the gameplay difficulty of the server.

• Mode 0: EASY
• Mode 1: NORMAL
• Mode 2: MODERATE
• Mode 3: HARD
• Mode 4: CUSTOM - This will generate a DMPGameplaySettings.txt file you can edit.

####whitelisted Enable whitelisting on the server. The commands are /whitelist [add|del] playername or /whitelist show.

• 0 : Off
• 1 : On

####modcontrol Enables or disables modcontrol - Only turn this off if you are running a private server where everyone has the same mods.

• 0 : Off
• 1 : On (Don't sync vessels with invalid parts)
• 2 : On (Prevent vessels with invalid parts from launching)

####keeptickingwhileoffline Specify if the the server universe 'ticks' while nobody is connected or the server is shut down.

####sendplayertolatestsubspace If true, sends the player to the latest subspace upon connecting. If false, sends the player to the previous subspace they were in. NOTE: This may cause time-paradoxes, and will not work across server restarts.

####useutctimeinlog Use UTC instead of system time in the log. This is useful if you want to co-ordinate logging between the server and client.

####loglevel Minimum log level to display. While DMP is in alpha, it's recommended to leave this on DEBUG (0) if you want to submit bug reports. ;)

####screenshotsperplayer Number of screenshots to save. You need to have a number higher than -1 in order for players to view screenshots for players they are not currently watching.

• -1 is disabled.
• 0 is unlimited.

##Mods Read DMPModControl.txt, it's commented/documented. The file can be copied from a development KMPServer (The one where you can use SHA sums, not the one with the !md5 section) as the file format is the same.

If you are running a private server, it's safe enough to just add the missing parts.

You can get the DMP client to make a DMPModControl.txt file specific for your GameData directory by pressing Options -> Generate DMPModControl.txt file. The whitelist option will only allow you to connect with the mods in your GameData directory. The blacklist option will allow you to connect with any mods.
