An object of a type convertible to 'TileBase' is required

This error message usually occurs when you are trying to use a method or function that requires an object of type 'TileBase', but you are passing in an object of a different type that cannot be converted to 'TileBase'.

To fix this error, you need to make sure that you are passing in the correct type of object to the method or function. If you are not sure what type of object is required, you can check the documentation or consult with the developer who wrote the code.

In some cases, you may need to explicitly convert the object to 'TileBase' using a type conversion function or operator. However, this should only be done if you are certain that the object can be safely converted to 'TileBase' without losing any important information or functionality.
