Brilliant game. I've got on my Arduboy at the moment.

[Slade]

I'm glad you like it.

We should all be thanking Stephanie for writing it in the first place. And probably thanking the Arduino platform for being so easy to move between hardware. It took around 30 minutes to port across and tweak. Although I think it's possibly still a little too fast compared to the original.

[phil8715]

I just wish it saved high scores.

[Slade]

I've updated the code to include a simple eeprom save. It's somewhat dirty in that it just writes to the very beginning of the eeprom space and doesn't care if there is data there. It also reads back the same data, but I cleared my eeprom before hand, so if you have data in the same spot, it may well read too much info back in.

There needs to be a much easier way to handle the eeprom.

Something along the lines of

write (data, length)

and

read (data,length)

Get / Put work in that fashion, but there's no way to check to see the space is free. Which makes me wonder why there isn't a

findfreespace() command ? It returns the beginning of the free space and the size of the chunk.

I'm rambling now Enjoy the game with saved high scores.

[Dreamer3]

write (data, length)

and

read (data,length)

You could implement both of these yourself easily with a for loop. Of course they still need to take an EEPROM address. The whole issue of free vs used is a whole other can of worms... but just writing an object to EEPROM should be pretty trivial.

Have to try this. Was always my favorite of the one button games like this.

[phil8715]

When I try to install the ino 2 file it comes up as a board error.

Always give full details of errors please. They give important information that will allow us to assist you.

@phil8715,
You have 2 copies of SFCave.ino in the SFCave folder. The second one is named SFCave (2).ino

Delete SFCave.ino and then rename SFCave (2).ino to SFCave.ino

[phil8715]

Great, all done, works perfectly!

Thank You @MLXXXp

[MLXXXp]

Which makes me wonder why there isn't a findfreespace() command ?

How do you define what free space is? EEPROM is just a 1K block of non-volatile storage that anyone can write any value to at any location.

If you want to turn that 1K block into some kind of a file system, there's a long ongoing thread about that.

Shared EEPROM storage management across multiple apps

Thinking of how to manage EEPROM storage for multiple apps (assuming someone will play multiple games over time and re-flash their devices but may switch games periodically and still want to restore game state (high scores, saved games, etc) from the previous app. My goals: Simple, easy to allocate whether 5% full or 95% full Apps can request the amount of ROM they need (be it 5 bytes or 50). Avoid issues of memory ordering or data fragmentation (we do not want to have to run a periodic def…

[phil8715]

Is there a way to reset high scores back to zero? It's stuck at 30032.

I can only get to 500ish so far.

[MLXXXp]

Any sketch that saves high scores in EEPROM should include a way to reset them, SFCave included.
Hopefully @slade will add this.

Until then, this sketch should do it (I haven't actually tested it):

#include <Arduboy2.h>
#include <EEPROM.h>

Arduboy2 arduboy;

void setup() {
  arduboy.begin();
  arduboy.clear();
  arduboy.print("Press B + LEFT\nto reset SFCave\nhigh score");
  arduboy.display();
  while (!arduboy.pressed(B_BUTTON + LEFT_BUTTON)) { }
  EEPROM.put(EEPROM_STORAGE_SPACE_START, (unsigned int) 0);
  arduboy.print("\n\nDone!");
  arduboy.display();
}

void loop() {
}

Ask and ye shall receive...
Just don't ask the hard stuff.

I've left more semicolons out and wondered why things don't work than I can remember. A lot of people might look down on VB.net, but it's much easier to use than C++. Ah well, it's good to learn new things, and I am, thanks to the Arduboy.

Ok. So I've added:

High Score clearing with B + Left.
Splash screen
Fixed button code. Uses the actual A button now !
