特性 (Attribute) 是可以放在脚本中的类、属性或函数上方来指示特殊行为的标记。例如，__HideInInspector__ 特性可以添加到属性声明中，从而防止该属性（即使是公共属性）显示在检视面板中。在 JavaScript 中，特性名称以“@”符号开头，而在 C# 中，它包含在方括号内：
// JS
@HideInInspector
var strength: float;
// C#
[HideInInspector]
public float strength;
Unity 提供了若干特性；请查看脚本参考（从侧栏的弹出菜单中选择 Editor 或 Runtime Attributes 部分）了解这些属性。.NET 库中还定义了一些有时可能在 Unity 代码中很有用的特性。
注意：不应使用 .NET 库中定义的 ThreadStatic 特性，因为如果将其添加到 Unity 脚本，会导致崩溃。
