MaterialGroup class Materials

A set of materials that one value is pushed to at once.

A member that does not declare the name, or declares it with a different type, is skipped, so one group can span a heterogeneous set (every enemy, prop, and tower in a blast radius) without a partial write, unlike MaterialParameters, which throws on an unknown name or a type mismatch.

Constructors

MaterialGroup([Iterable<PreprocessedMaterial> materials = const []])

Groups materials, or none, to be added later.

MaterialGroup.of(Node root)

Every PreprocessedMaterial reachable from root's subtree.
