About this mod Author’s original text
LessSleep
Sleep voting for Valheim dedicated servers: skip the night before every single player is
in bed, if enough people agree.
- Server-driven: the server decides when to ask and when the night skips.
- No client is required: on a server where nobody runs the mod, it silently behaves like
auto-skip (see How it works).
- Clients get a prompt: awake LessSleep clients see a message and can vote with Y / N
or by typing yes / no in chat.
How it works
- When at least PercentInBedToStartVote (default 50%) of online players are in bed
(and at least MinimumPlayersInBed), the server opens a vote.
- Sleeping players are treated as a yes (they are the ones asking - it's their night too).
- Awake players running LessSleep are asked to accept or decline.
If no awake player runs LessSleep, the vote passes immediately (auto-skip).
- The vote passes when at least VotePercentOfAwakeToPass of awake modded players accepted,
and fails on timeout or when everyone voted no.
- On a pass the server skips to morning exactly like vanilla sleeping does.
Installation
Server
Install BepInExPack_Valheim and drop LessSleep.dll into BepInEx/plugins on the server.
Clients (optional, but recommended)
Same thing: install BepInExPack_Valheim, drop LessSleep.dll into BepInEx/plugins.
Clients without the mod still see the vote messages and the night still skips for them,
they just cannot cast a vote.
Configuration
Server config (BepInEx/config/LessCx.LessSleep.cfg):
| Setting | Default | Description |
| --- | --- | --- |
| PercentInBedToStartVote | 50 | Percentage of online players that must be in bed to start a vote. |
| MinimumPlayersInBed | 1 | Minimum number of players in bed before a vote can start. |
| VotePercentOfAwakeToPass | 50 | Percentage of awake LessSleep clients that must accept. |
| VoteTimeoutSeconds | 30 | How long a vote stays open. |
| VoteCooldownSeconds | 60 | Wait after a failed vote before a new one can start. |
Client config:
| Setting | Default | Description |
| --- | --- | --- |
| EnableVotePrompt | true | Allow voting with the Y and N keys. |
| AllowChatYesNo | true | While a vote is open, typing yes or no in chat casts your vote. |
Notes
- The server never needs to know which clients run the mod to skip; the modded-client list
is only used to decide who gets asked.
- Voting is intentionally simple: one vote per player, last vote wins, votes are only accepted
from connected players that announced themselves.
Building
dotnet build src/LessSleep.csproj -c Release./scripts/pack.sh # produces dist/LessCx-LessSleep-.zip
Reference paths default to the macOS Steam install and can be overridden:
dotnet build src/LessSleep.csproj -c Release \
-p:ValheimManagedDir=".../Steam/steamapps/common/Valheim/valheim.app/Contents/Resources/Data/Managed" \
-p:BepInExCoreDir=".../Steam/steamapps/common/Valheim/BepInEx/core"
CI / releasing
| Workflow | Trigger | What it does |
| --- | --- | --- |
| build | push to main, pull requests | compiles and uploads the package as a build artifact |
| publish | tag vX.Y.Z or manual dispatch | stamps the version, builds, publishes with tcli, creates a GitHub release |
CI has no game install, so.github/actions/prepare-refs downloads the Valheim dedicated
server with SteamCMD (anonymous) and the BepInEx core into a cached.refs/ directory. Game DLLs are never committed to this repository. When Valheim updates,
bump the cache key in.github/actions/prepare-refs/action.yml so CI picks up fresh
reference assemblies.
One-time setup: create a service account for the LessCx team
(Settings > Teams > LessCx > Service Accounts) and store its token as a repository secret:
gh secret set TCLI_AUTH_TOKEN --repo LovelessCodes/LessSleep
Release: bump version_number in manifest.json (and CHANGELOG.md), commit, then:
git tag v1.0.1 && git push origin v1.0.1
The publish workflow stamps that version everywhere, so the tag is the source of
Install & use Install: BepInEx plugin
- The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
- Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
- Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
- Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.
Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.
Install these first, or the mod will not work:
