Odin Inspector 系列教程 --- Validate Input Attribute

本文主要是介绍Odin Inspector 系列教程 --- Validate Input Attribute，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

Validate Input Attribute特性：用于任何属性，并允自定义检查器，灵活实现多种监测规则。使用此选项可强制执行正确的值（提供对应的返回值）。

常规写法，实参输入一个方法的名称，一个对应的消息

    [ValidateInput("MustBeNull", "这个字段应该为空。")]public MyScripty DefaultMessage;private bool MustBeNull(MyScripty scripty){return scripty == null;}

也可以使用$特殊标识符引用一个字段动态显示提示信息，而且也可以明确指出需要提示信息的类型

    [ReadOnly]public string dynamicMessage = "这个物体不应该为空！";[ValidateInput("CheckGameObject", "$dynamicMessage", InfoMessageType.None)]public GameObject targetObj_None = null;[ValidateInput("CheckGameObject", "$dynamicMessage", InfoMessageType.Info)]public GameObject targetObj_Info = null;[ValidateInput("CheckGameObject", "$dynamicMessage", InfoMessageType.Warning)]public GameObject targetObj_Warning = null;[ValidateInput("CheckGameObject", "$dynamicMessage", InfoMessageType.Error)]public GameObject targetObj_Error = null;private bool CheckGameObject(GameObject tempObj){return tempObj != null;}

当然也可以这么用

    [ValidateInput("IfNullIsFalse", "$Message", InfoMessageType.Warning)]public string Message = "Dynamic ValidateInput message";private bool IfNullIsFalse(string value){return string.IsNullOrEmpty(value);}

也可以覆盖默认的提示消息和消息类型

 [ValidateInput("HasMeshRendererDynamicMessage", "对应的函数中已经有消息，所以这个默认消息已经没用")]public GameObject DynamicMessage;private bool HasMeshRendererDynamicMessage(GameObject gameObject, ref string errorMessage){if (gameObject == null) return true;if (gameObject.GetComponentInChildren<MeshRenderer>() == null){errorMessage = "\"" + gameObject.name + "\" 这玩应必须有一个 MeshRenderer 组件";//如果设置消息，则默认消息会被覆盖return false;}return true;}[ValidateInput("HasMeshRendererDynamicMessageAndType", "对应的函数中已经有消息和类型，所以这个默认消息和类型已经没用")]public GameObject DynamicMessageAndType;[InfoBox("Change GameObject value to update message type", InfoMessageType.Info)]public InfoMessageType MessageType;private bool HasMeshRendererDynamicMessageAndType(GameObject gameObject, ref string errorMessage, ref InfoMessageType? messageType){if (gameObject == null) return true;if (gameObject.GetComponentInChildren<MeshRenderer>() == null){errorMessage = "\"" + gameObject.name + "\" 要有一个 MeshRenderer 组件";//如果设置消息，则默认消息会被覆盖messageType = this.MessageType;//如果设置消息类型，则默认消息类型会被覆盖return false;}return true;}
