Thanks Quark, I actually use 2.1.2 version because I’m afraid all my old programs could find bugs with new versions, but I know it’s not a good practice and I’ll take time to update the processing version and review my programs.
But anyway “I tried an old program witch use ControlFrame and it works with same processing version an same libraries???” I continue to searche the reason and tell you if I find.
have a good weekend
Under the hood there were massive important differences between Processing 2 and Processing 3 and many libraries had to be modified to work with Processing 3. I had to completely rewrite the guts of my own library G4P to make it V3 compatible.
It does mean that some sketches created in Processing 2 with P2 compatible libraries will not run in P3 even with updated libraries without changing the sketch code. In some cases the effort in modifying the sketch might be quite significant or complex.
