Unity 2017 UnityScript子类变量歧义：如何指定本地preview变量

The ambiguity error you're seeing comes from the fact that both your CameraMotionBlurEditor subclass and the parent Editor class have a variable named preview. To explicitly target your subclass's local variable instead of the inherited one, you can use the this keyword to qualify the reference.

Corrected Code Example #

Update your OnInspectorGUI method to use this.preview to specify the local subclass variable:

function OnInspectorGUI () { 
    if (this.preview.boolValue) {
        dosomething();
    } 
}

Why This Works #

In UnityScript (Unity's JavaScript-based scripting language), the this keyword refers directly to the current instance of your subclass. By prefixing preview with this., you're telling the compiler to prioritize the SerializedProperty you declared in CameraMotionBlurEditor over any identically named variables inherited from the parent Editor class. This eliminates the ambiguity and ensures you're accessing the correct variable.
