fromFlatbuffer static method

UnlitMaterial fromFlatbuffer(Material fbMaterial, List<Texture> textures)

Builds an UnlitMaterial from a flatbuffer material description, resolving texture indices against textures.

Throws if fbMaterial is not an unlit material.

Implementation

static UnlitMaterial fromFlatbuffer(
  fb.Material fbMaterial,
  List<gpu.Texture> textures,
) {
  if (fbMaterial.type != fb.MaterialType.kUnlit) {
    throw Exception('Cannot unpack unlit material from non-unlit material');
  }

  UnlitMaterial material = UnlitMaterial();

  if (fbMaterial.baseColorFactor != null) {
    material.baseColorFactor = Vector4(
      fbMaterial.baseColorFactor!.r,
      fbMaterial.baseColorFactor!.g,
      fbMaterial.baseColorFactor!.b,
      fbMaterial.baseColorFactor!.a,
    );
  }

  if (fbMaterial.baseColorTexture >= 0 &&
      fbMaterial.baseColorTexture < textures.length) {
    material.baseColorTexture = textures[fbMaterial.baseColorTexture];
  }

  return material;
