Simulation stops after certain UI elements are used - processing

Question

Im working on a project in processing, and I'm having some difficulty with this super annoying bug. All the code is pasted below, 4 class files.
Whenever the "Simulation speed" slider is moved up and then moved back down, the simulation will stop giving no errors. Same thing with the "Auto" button. I have no idea why this is occurring and I've gone through my code following the variables and I don't see anything wrong.
Help!

Thank you! Sorry if the code is a little messy :)

Answer 1

In your main file, this block relies on the values of those two controls:
if(frameCounter == simulationSpeed && autoScrollButton.buttonActive){
k++;
frameCounter = 0;
setHeight();
}
When that gets skipped (because you changed simulationSpeed or buttonActive), your frameCounter gets out of sync with simulationSpeed so the block continues to get skipped.
