SerializedProperty.numericType

描述

返回整数和浮点属性的精确类型。（只读）

The propertyType 属性将所有支持的整数类型归类为 SerializedPropertyType.Integer，并将单精度和双精度浮点类型归类为 SerializedPropertyType.Float。此属性公开了精确类型，例如 SerializedPropertyNumericType.UInt8 和 SerializedPropertyNumericType.Double，比使用基于字符串的 type 属性更有效。对于枚举属性 (SerializedPropertyType.Enum)，它返回基础类型。对于非数值类型，它返回 SerializedPropertyNumericType.Unknown。
