DoppelNames

An add-on for Doppel (by RUDYHILL) that gives your bots random names, with a join/leave message everyone can see.

• Spawn a bot: it gets a random name like Timmy, floating above its head, and a pop-up says "Timmy has joined the server". The name tag is LabFusion's own player nametag (same look, font, height and size scaling as a real player's), so it needs LabFusion installed.
• Remove the bot: "Timmy has left the server".
• With LabFusion, the other players in the lobby see the same name tag and the same pop-ups.

It is a separate mod, so Doppel.dll is not touched and Doppel can update normally.

Host-only mode (server-side bots) - experimental

If you are the host, you are the only one who needs the mods. With ServerSideBots = true (the default) every bot you spawn joins the lobby as a fake LabFusion player: other players, who have nothing extra installed, see the bot's body moving, a normal player nametag, and Fusion's own "joined" / "left" notices.

Limits of this mode:

• It is untested by its author. It may glitch, or print Fusion errors on other players' screens.
• Other players cannot hit or grab the bot, and the bot is not in your own Fusion player list.
• Bots only appear for players who are in the lobby; someone who joins later gets them after ~1.5 seconds.
• If anything goes wrong, set ServerSideBots = false in UserData/MelonPreferences.cfg and restart.

When you are not the host (or the mode is off)

Fusion only sends the names to people who have this add-on. Everyone in the lobby who should see the tags and pop-ups needs DoppelNames.dll in their Mods folder (and Doppel, same as before). Players without it just don't see the extra stuff; nothing breaks for them.

Settings

After the first run, UserData/MelonPreferences.cfg has a [DoppelNames] section:

To change the wording, search Mod.cs for has joined the server and has left the server. To change the name list, edit the Names array.

How it works

• Doppel keeps all bots in BotManager.bots. The add-on watches that a few times a second and notices bots appearing and disappearing.
• The name is also written to Doppel's own Bot.nameIs, so Doppel's log lines use it.
• The name tag is created with LabFusion's RigNameTag and RigHeadUI (the classes Fusion uses for players) and moved above the bot's head every frame, so it is the real player nametag, not a copy.
• Over the network it uses its own LabFusion message (registered the same way Doppel registers its own). The owner sends joined / left events plus a short name list every few seconds, so someone who joins the lobby later still gets the tags.
• Other players' bots appear on your screen as "puppets". They are matched to the right name by (owner id, bot id), which is how Doppel matches them too.

In-game menu

Open BoneMenu > DoppelNames:

• Type a bot name: every new bot gets that name.
• Copy a player's name: shows the players in your lobby (press Refresh player list after people join); tap one and every new bot gets their exact username.
• Back to random names: clears both.
• Switches for name tags, pop-ups and host-only mode.

New bots pick up the choice when they spawn; bots already out keep their old name.

How host-only mode works

For each bot the add-on makes a fake Fusion player id, tells each remote player directly "this player joined" (the same message the host sends for real joins), then about 20 times a second sends the bot's pose as that player, and finally a "player left" message. Everything goes to each remote player one by one, never as a broadcast, so your own game doesn't spawn a second copy of the bot.

Players who also have Doppel

DoppelNames stops Doppel's own bot sharing for bots that are shown as server-side players, so those players see each bot once (with its name) instead of twice.

Known limits

• Without LabFusion the pop-ups still work, but there are no name tags (they come from Fusion).
• Written against Doppel 1.4.0, LabFusion 1.14.x, BoneLib 3.2.x, MelonLoader 0.7.x. A different Doppel version may rename the fields it reads; the log will say so ("looks like a different version").
• Changing levels clears the bots, so pop-ups are muted for about 4 seconds after a level change.
• If you spawn a bot while alone in the lobby, the tag shows for you right away. Players who join later get the name within a few seconds, but no "joined" pop-up for it.

Face slightly off for other players

In the DoppelNames menu use Face: move left / right (10 mm per press) until the face lines up on a friend's screen. Saved as HeadShiftX / HeadShiftZ. The log also prints the head and pelvis positions of each bot when it first sends a pose.
