Offline Fake Player Accounts

This page covers the account-fetcher setting: what it does, and how to switch it to OFFLINE so your fake players are generated locally instead of being looked up through the MineTools or PlayerDB online services. Use OFFLINE when you want fake players with completely custom usernames, zero external API calls, and no dependency on an internet lookup service.

What "offline fakes" actually means: By default, HalosPlayerSpoofer fetches each fake player's account data (UUID + skin texture) from an online service. In OFFLINE mode it skips that entirely. It builds the account itself from the username, exactly the way a Minecraft server generates UUIDs for offline-mode players, so no HTTP request ever leaves your server for account data.

How account fetching works

The account-fetcher setting in plugins/HalosPlayerSpoofer/config.yml decides where the plugin gets each fake player's account and texture data:

Value	What it does	Skins?	Custom usernames?	External calls?
MINE_TOOLS	Looks up account + skin from MineTools	✅ Real skins	❌ Name must be a real account	✅ Yes
PLAYER_DB	Looks up account + skin from PlayerDB	✅ Real skins	❌ Name must be a real account	✅ Yes
OFFLINE	Generates the account locally from the username	❌ Default skin only	✅ Any username you want	❌ None

With MINE_TOOLS or PLAYER_DB, the fake player's username has to match a real, registered Minecraft account, because that's what the service resolves. If it can't find the name, the fake fails to fetch.

OFFLINE removes that restriction. The UUID is derived directly from the username (OfflinePlayer:<name>, the same scheme Minecraft itself uses in offline mode), so you can use any username you invent and there are no rate limits, timeouts, or network dependencies.

The trade-off: Offline fakes have no custom skin. Because textures only come from the online fetchers, an OFFLINE fake renders with the default Steve/Alex skin. If real skins matter more to you than custom names, use MINE_TOOLS or PLAYER_DB instead. Those work on an offline-mode server too, you'll just be limited to usernames of real accounts.

OFFLINE only works on an offline-mode server. If the server is in online mode the plugin will reject the OFFLINE fetcher, since a locally-generated account can't authenticate against Mojang.

Switching to OFFLINE mode

Step 1: Set the account fetcher to OFFLINE

In plugins/HalosPlayerSpoofer/config.yml, find the account-fetcher setting and change it to OFFLINE:

# Where to fetch player account and texture data.
# Possible values: MINE_TOOLS, PLAYER_DB, OFFLINE.
# When your server is running in online mode, this may not be OFFLINE.
account-fetcher: OFFLINE

# The HTTP timeout the account fetcher uses.
# Not used in OFFLINE mode since no requests are made.
account-fetcher-timeout: 2s

Step 2: Restart

Restart the server, to apply the change.

Step 3: Verify

Confirm it's working using the Verifying it works section below.

Verifying it works

1. Turn on debug logging temporarily. Set debug: true in config.yml and reload.

2. Add a fake player the way you normally would (via the Fluctuation module or your spoof command).

3. Add a fake with a made-up username that isn't a real account. In MINE_TOOLS/PLAYER_DB this would fail to fetch. In OFFLINE it should appear immediately, which confirms the online lookup is being skipped.

4. The fake will show the default skin (Steve/Alex). That's expected in OFFLINE mode and further confirms no texture was fetched.

5. Check the console. You should see no MineTools or PlayerDB request/timeout log lines for account fetching.

Turn debug back to false when you're done.

Troubleshooting

"OFFLINE fetcher is not allowed in online mode" (or fakes never spawn after switching to OFFLINE) The plugin only allows OFFLINE on an offline-mode server. Make sure the server is in offline mode, then fully restart.

Fake players have no skin Expected behavior in OFFLINE mode. Offline accounts carry no texture. If you need skins, switch to MINE_TOOLS or PLAYER_DB (those work on an offline-mode server too, but your fake usernames must be real registered accounts).

FAQ

Q: Why would I use OFFLINE instead of MINE_TOOLS/PLAYER_DB? A: Two reasons. You want fakes with any custom username (not limited to real accounts), and you want zero external API calls (no rate limits, no lookup timeouts, works with no internet).

Q: Can I have offline fakes and real skins? A: No. Skins come from the online fetchers. It's one or the other: custom names with no skins (OFFLINE), or real skins with real-account names (MINE_TOOLS/PLAYER_DB).
