hi,  
please format your code using in forum post editor the

```auto
</> code tag

```

* * *

if you have in your sketchbook path your project and also a file

> test.pde

( mans you see it in the processing IDE )  
it is already loaded  
and if that file contains functions  
you can call that directly from you “main”

You can‘t start another complete sketch this way.

Instead you need to unify both sketches.

When fermer is true then don’t display the button but draw the content of the unified 2nd sketch
