Modding Tutorials/ThingDef

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.

Pawns are NPCs.

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

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

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

These attributes can be used in all ThingDef types.
