Please help, code crashes and I can't figure out why

Hallowed31 · October 24, 2025, 7:56pm

Hello all. Time is getting thin, as is my ability to troubleshoot errors I do not understand.

My code interfaces with an Arduino Uno R4 Wifi and all the Arduino does is send messages over Serial to change the state of my Halloween Laser Maze game.

Any hints, obvious errors or solutions greatly appreciated (I’m just a dad, an Arduino hobbyist and I like to use Halloween as a project showcase and to hopefully get kids interested in coding/electronics).

The crash always seems to occur after about the fourth or fifth time running through the program and the flow works like: waiting state; start button pressed (“start” received by Processing over serial); some or no alarm trips (“alarm” and “off” received by Processing over serial); stop (“stop” rx over serial); reset button pressed (“reset” over serial). I am using Processing 4 and have Java version 8 installed on my Windows 11 PC, Update 461 (build 1.8.0_461-b11).

It doesn’t seem to matter what I set the memory to in Preferences, it’s either too low (out of memory) so I increase it as much as needed but the same crash happens

Hello @Hallowed31 ,

This suggests it is related to your NVIDIA drivers.
Try updating them.

Processing 4.
Which version? The latest is Processing 4.4.10
Sometimes a version can break things or fix things!

Java 8.
Processing uses it’s own bundled version and the error report shows the version.
This should not affect your Processing project.

The Asking Questions Guidelines here can be very helpful!
Welcome to the Processing Foundation Discourse

When did you start seeing the error?
I build my projects in stages, save a working version with comments and then start the next version.

:)

Hello again!

I could not run your code as is!

Testing:

Replaced all images, videos and wav files.
Commented out custom fonts.
Commented out missing references to classes.
Commented out import that was not provided.

I rarely do this but was curious and only took a few moments for me.

It is a good example of simulating input for testing.

I was able to replace serial input with simulate data:

// Array of valid command strings
String[] validCommands = {"alarm", "off", "start", "stop", "reset", "timewarp", "regtime", "destro", "mars"};

// Array of gameStages that correspond to each command
int[] validGameStages = {400, 400, 100, 400, 0, 400, 400, 400, 400};  

int serialSub(int i)
  {   
  return validGameStages[i];
  }
  
int ch = 0;
int counter = 0;
  
void keyPressed()
  {
  ch++;
  ch = ch%9;
  gameStage = serialSub(ch);
  println(counter, ch, validGameStages[ch], validCommands[ch] );
  counter++;
  }

Seems to work if I hit keys slowly.

It crashes if I hit keys to quickly with same error as yours:

You may be changing states too quickly!

Give this a try:

void gameReset() {
  //score = 0;
  //clicker = 0;
  //clickCounter = 0;
  //i = 3;
  //currentTimeVal = 1000.0;
  //introStarted = false;
  //alreadyUsedSpell = false;
  //isSlowed = false; // set flag so this only happens once per game
  //isDestro = false;
  ////textFont(font, 120);
  //fill(0, 200, 0);

  //if (intro.isPlaying()) {
  //  intro.stop();
  //}
  //if (cobred.isPlaying()) {
  //  cobred.stop();
  //}
  //if (green.isPlaying()) {
  //  green.stop();
  //}
  //if (alarm.isPlaying()) {
  //  alarm.pause();
  //}
  //if (Hydra.isPlaying()) {
  //  Hydra.pause();
  //}
  setup(); // Starts over!
}

I did comment this so above may have to be consideration when connecting to COM ports again (easy fix with a boolean variable) :
//connect(1, 24, 200); // 25 com ports*4 port numbers (buses)*2 tries each

Keep at it!

:)

Awesome, thanks for taking the time!

Sorry bout that. It has files and stuff in the data folder but you already know that (just saying for anyone else who comes across this thread).

and the rest of your suggestions: very slick. I admit your skill is beyond my brute force approach. I have no education or training in anything related to coding or electronics at all; I’m just a dad and Hallowe’en enthusiast. Thanks and i learned some from your example.

Came down more to not binding serial triggers to Processing very neatly. Maybe I was recursively calling the same files and crashing the program or maybe one wasn’t closing fast enough before the other began, or maybe it’s to do with the Serial class in the new Arduino Uno R4 wifi Renesas chip that I have read doesn’t work the same way as the ATMega328P from the Uno R3.

So, yes, in part. I revised the code where necessary to prevent accidental (or intentional given the intended users - kids at Hallowe’en) button spamming. I also added a char trigger from Processing to Arduino to let it know if the app has just launched or relaunched, so the Arduino resets to its gameState = 0; and is thus on the same page.

Your suggestion to just recall setup(); I considered but ultimately, there are other things going on that I don’t want to mess with there, plus it has to be quick and the way I have it is my style (for better or worse) throughout all my Hallowe’en “parlour” arcade-type games.

I did after you suggested it. Did it fix anything? Well, it didn’t hurt anything so…

In the end, it seemed to be a problem with not closing up audio files or movies when the Serial triggers came in from the Arduino, that was causing the very frequent crashes.

Thanks again for taking a look! There’s still a few days before the we’en so if you happen to have two Arduino Uno R4 wifis, a few pushbuttons, a TSOP38238 IR receiver, a few lasers (I bought some from Amazon but have used holiday decorative ones that I hacked to emit a straight green beam), and a few relays, I can say that this project is a favorite among the trick or treaters, which is why I keep making different versions and running it annually.

Revised Processing code:

/* v1_7: Oct 25, 2025 12:56

Just a single tab version of 1.5 in Processing 4.4.10 for export to app
Added char 'L' trigger in setup() to let Arduino know Processing
  just launched/relaunched so Arduino resets states to initial ones
  
Overall stability seems ok for now. Fix seems to be really dialing in
Serial states and closing up files when not using.

Many functions adapted/taken from the open source work of others.
