So I made a project in processing and I used VSCode processing extension as the editor. In the code I created:

```processing
abstract class Obstacle{...}
class Rectangle extends Obstacle{...}
class Beam extends Obstacle{...}
class Ellipse extends Obstacle{...}

```

And then the editor popped out the error:

```auto
The class “Beam” cannot have the same name as your sketch or its enclosing class

```

When I renamed the Beam class to something else, the error disappears shortly, but when I restarted VSCode it appears again, no matter what I rename it to. Weirdly other classes did not error, which have the exact same inheritance and structure.

I didn’t get this error using the [processing.org](http://processing.org)’s editor, so that’s kinda weird. Does anyone using VSCode know if it’s an editor issue or my code issue?

Maybe you have the name “Beam” as 1 of your project’s filenames? 🤔

Maybe the “VSCode Processing Extension” is still caching the original class name somehow? 🤷‍♂️
