This is the main class of the mod. The idea behind this was that vanilla duck game modding only allows you to add items by extending thing, and then using [EditorGroup...]. This class allows you to hook into duckgame on any level, and apply your logic to duckgame at any time.

The events in here use a generic handler, which makes it pretty easy to hook into. This is an example of hooking into an event:
Here are the events:

• onLevelUpdated -> Invoked each time the level is updated (the game tick)
  
• onDucksSpawned -> Invoked at the beginning of a level (first frame containing ducks)
  
• onLevelInitializing -> Invoked when the level is initialized (or possibly slightly after)
  
• onLevelTerminated -> Invoked when the level is terminated

The other one's I haven't used or tested much personally, but they should fire whenever those functions are fired on a normal object

This class is used to register a custom sound to be used with a team (builtin or custom). Huge thanks to https://steamhost.cn/steamcommunity_com/id/king_potato, the creator of GCN Items. I read through their source code to figure out how to play SFX sounds.
Anyway, to use this class, call HatsWithSounds.AddSoundToHat(Team team, string soundFilePath). It should look something like this:
