MetadataClassProperty

数组元素的数量。仅为固定大小的数组定义。 The number of array elements. Only defined for fixed-size arrays.

属性的组件类型。这包括整数（例如 INT8 或 UINT16）和浮点（FLOAT32 和 FLOAT64）值 The component type of the property. This includes integer (e.g. INT8 or UINT16), and floating point (FLOAT32 and FLOAT64) values

未定义实体的属性值时使用的默认值。 A default value to use when an entity's property value is not defined.

属性的描述。 The description of the property.

属性的枚举类型。仅当类型为 ENUM 时定义。 The enum type of the property. Only defined when type is ENUM.

包含扩展的对象。 An object containing extensions.

额外的用户定义属性。 Extra user-defined properties.

房产的 ID。 The ID of the property.

如果属性是数组（固定长度或可变长度），则为 true，否则为 false。 True if a property is an array (either fixed length or variable length), false otherwise.

如果属性是可变长度数组，则为 true，否则为 false。 True if a property is a variable length array, false otherwise.

存储此属性的最大允许值的数字或数字数组。仅当 type 为数字类型时才定义。 A number or an array of numbers storing the maximum allowable value of this property. Only defined when type is a numeric type.

存储此属性的最小允许值的数字或数字数组。仅当 type 为数字类型时才定义。 A number or an array of numbers storing the minimum allowable value of this property. Only defined when type is a numeric type.

属性的名称。 The name of the property.

表示空值的无数据哨兵值 The no-data sentinel value that represents null values

属性是否标准化。 Whether the property is normalized.

作为值转换的一部分添加到属性值的偏移量。即使“hasValueTransform”为“false”，它也始终被定义。如果类属性 JSON 本身没有定义它，那么它将被初始化为默认值。 The offset to be added to property values as part of the value transform. This is always defined, even when `hasValueTransform` is `false`. If the class property JSON itself did not define it, then it will be initialized to the default value.

是否需要属性。 Whether the property is required.

作为值转换的一部分，要与属性值相乘的比例。即使“hasValueTransform”为“false”，它也始终被定义。如果类属性 JSON 本身没有定义它，那么它将被初始化为默认值。 The scale to be multiplied to property values as part of the value transform. This is always defined, even when `hasValueTransform` is `false`. If the class property JSON itself did not define it, then it will be initialized to the default value.

描述应如何解释此属性的标识符。 An identifier that describes how this property should be interpreted.

属性的类型，例如 SCALAR、VEC2、VEC3 The type of the property such as SCALAR, VEC2, VEC3

确定存储在 GPU 上的单个属性元素的字节大小。 This differs from the CPU byte size if the element type is a 64-bit type that can be downcast to a 32-bit type for texture packing (only relevant for textures created from property tables). Determines the byte size of a single property element, stored on the GPU. This differs from the CPU byte size if the element type is a 64-bit type that can be downcast to a 32-bit type for texture packing (only relevant for textures created from property tables).
