EditorToolContext

설명

Use this class to implement specialized versions of the built-in transform tools. Built-in transform tools include Move, Rotate, Scale, Rect, and Transform.

    // Tool contexts can also implement an OnToolGUI function that is invoked before tools. This is a good place to
    // add any custom selection logic, for example.
