ThingDef is a def type for making entities, such as buildings and pawns (NPCs).


Buildings

Buildings are static entities. They usually require construction and perform a special function.

Elements

Pawns

Pawns are NPCs.

Items

Items are anything that can be hauled, such as weapons, debris, or resources.

Plants

Plants grow in growing areas, in the landscape, in a hydroponics table, or in a plant pot.

Elements

Filth

Filth is just an image that is overlaid above the floor. It contributes to the "ugly environment" thought in pawns.

Global elements

These elements can be used in all ThingDef types.
