Our shit was everywhere. We had a sounds folder, a models folder, a textures folder, a prefabs folder, an entities folder, an items folder, an icons folder. That sounds pretty organised, but it’s a fucking nightmare. Want to add a new entity? Easy, create the item, put it in the items folder, create the entity prefab, in the entities folder, the entity code goes in the scripts folder, sounds clips go in sound clips, sound definitions go in sound definitions, item icon goes in the icons folder. Grr.
So I reorganised everything. Now if you want to add a weapon it goes in the Prefabs/Weapons// folder. Everything the weapon needs goes in that folder. So if you want to delete that weapon, you delete the folder. If you want to find a weapon’s item, it’s in that folder.
This doesn’t affect you at all, but it affects modders. So if you have a server mod and you’re wondering why everything is broke, it’s probably because a prefab it’s looking for has changed location. Sorry.
