Incompatible Names

Because of Bridge code translation and the mechanism of Bridge class availability in a browser, users may encounter naming collisions with C# classes and MonoBehaviour fields.

For example, if a class such as JSON is defined, the class overrides the default window.JSON class and causes errors.

In order to prevent such problems, we have made a list of names that we recommend avoiding when choosing C# class names or MonoBehaviour field names.

Due to the length of this list, consider to use Page Search (CTRL+F / CMD+F).
