BetterCoop

한국어

Two scouts, one body: the Carrier has the keyboard, the Rider has the mouse, and they live and die together. Pray for a partner who knows the way, and not one who eats every mushroom.

How it plays

Carrier (keyboard)	Rider (mouse)
Move, jump, sprint, crouch	Look and steer
Interact, pick up, drop, throw	Use the held item
Hotbar, emotes, open the backpack wheel	Scroll, ping, pick from the backpack wheel

• The Roster in the ESC menu shows who carries whom, and the Run Report hands out Merit Badges to the steadiest back and the comfiest passenger.
• Everyone who wants a partner needs the mod. Anyone without it can still join the Run, but makes the climb alone, and a little lonely.
• BetterCoop gets along with other mods, though its rules win while you are in a Pair. It steps aside for Co-op Mod, which does the same job, and for a game update it has not caught up with.

Settings

The Troop Leader sets the Run Rules on the Roster, where each one is explained: Honour Role Preferences, Allow Role Swaps, Late Pairing, Allow Odd Player Count, Campfire Shuffle, Timed Shuffle, Hand Over Place and Items, Rescue Carry, Carry Weight, and Rider Picks From Backpack. Each player sets their own Role Preference there. If the climb keeps going wrong and it is not your partner's fault, turn on Verbose Log in your mod manager's config and send BepInEx/LogOutput.log with your bug report.

For mod developers

BetterCoop.Api lets another mod read the Pairs without depending on BetterCoop's internals: Enabled (false while the mod is off, or sits out a room whose Troop Leader's version does not work with this one), RoleOf(character), TryGetPartner(character, out partner), TryGetSharedBody(character, out body) (a Rider plays through their Carrier's body), and the events PairsChanged, PairChangeStarting, and PairChangeFinished. ApiVersion rises only when a change breaks callers. A Rider's own character is idle while carried and its statuses are kept clear, so a mod that shows players' status should show the Shared Body instead.

Reference BetterCoop.dll as a soft dependency and keep the calls in a method of their own, so your mod still loads without BetterCoop:

[BepInDependency("in.kawala.bettercoop", BepInDependency.DependencyFlags.SoftDependency)]
public class MyPlugin : BaseUnityPlugin
{
    static bool HasBetterCoop => Chainloader.PluginInfos.ContainsKey("in.kawala.bettercoop");

    static bool IsRider(Character character) => HasBetterCoop && IsRiderInBetterCoop(character);

    [MethodImpl(MethodImplOptions.NoInlining)]
    static bool IsRiderInBetterCoop(Character character) =>
        BetterCoop.Api.RoleOf(character) == BetterCoop.Api.Role.Rider;
}

Antivirus warnings

Some antivirus programs flag BetterCoop.dll by a machine-learning guess, a name ending in !ml, as they often do with mods. Allow the file and install the mod again. The source is open at https://github.com/kawalain/peak-better-coop.
