Type Alias TraitDefinition

What a trait is at runtime: which properties it puts on an item, and whether they belong in json.

type TraitDefinition = {
    defaults?: () => Record<string, unknown>;
    keys: string[];
    serializable?: boolean;
}

Properties

defaults?: () => Record<string, unknown>

The data a new item gets when it is given the trait.

keys: string[]

The properties the trait puts on an item.

serializable?: boolean

False for properties which only make sense where the item lives (an element): they are left out of json.
