Common tasks

Run a method of yours just before a game method runs. The last two arguments say which method of yours to run: its type and its name.

bool ok = Mod.Prefix(typeof(TimeOfDayAzure), "IncreaseDayCounter", typeof(Helpers), "AfterDay");

A game method can have several versions with the same name. For those, use the version of Prefix, Postfix or Finalizer that also takes an array of argument types, such as new[] { typeof(int) }, to say which version you mean. See the Reference below.

Run something once a save is ready. If a save is already loaded, it runs straight away.

Events.WhenReady(() => Log.Info("save ready"));

If your mod is a BepInEx plugin and not a framework mod, get the handle from the plugin.

CoreMod mod = CoreMod.For(this);
mod.Log.Info("ready");
