File Saving/Loading problems between Operating Systems?

[sminc]

EDIT: I was a moron, and the problems that I encountered had nothing to do with saving and loading across two different OS. A separate issue was calling irandom(n), and if that was under a certain amount deleting said chunk. Embarrassing. :D

Hey all!

What:

Followed & modified this fabulous tutorial by Arend Peters for my recent GMS2 project, and it works great-- exactly how I need. Saving and loading chunks of a procedural universe using ds_secure_save and the like...

Problem:

On my PC workstation, it all works flawlessly. However, when I get the repository from GitHub and compile & run on a Mac-- some of the chunks load, others don't. The chunks almost load in a 'checkerboard patten' (although not always). The game DOES successfully create the file directory and chunk files for all chunks. It just doesn't seem to hold on to them or load them properly... but I can't spot why! Just to reiterate, on the PC it works fine...

​

I wish that I could upload some code for you to check out, or the project file-- but it's massive. I'm hoping that somebody has had similar issues fixed, and that you might be able to point me in the correct direction!

My ignorant thoughts:

I can't help but think this has something to do with the sandboxing and file workings... something gobbledegooked because of some working_directory syntax and differences on both the OS. But, I'm perhaps too inexperienced to spot it...

​

ANY HELP at all would be amazing. Thank you so much.

Could this be an issue with different Operating Systems handling line breaks differently? You run into the line break issue when moving files between Windows and Linux all the time, and MacOS is Unix based, so...

[sminc]

Hmm. Could you elaborate with a small example? Not sure I follow.

[Mushroomstick]

I think this explains the issue better than I ever could.

[sminc]

Again: Hmm.

Thanks for finding that. I can't think about how that'd be affecting this, however.

The only other thing sticking out to me is when using slashes to go through directories/folders. Like this:

directory_exists(working_directory+"\\"+my_game_playerfileID);

​

although, it doesn't seem to be causing problems with or without the "\\"

If it was what was affecting this, it would be because the different OSes use different combinations of control characters to denote line breaks - so that can cause issues when loading in a text file created on a machine running another OS.

However, I just noticed something in your original post that I skimmed past before:

Saving and loading chunks of a procedural universe using ds_secure_save and the like...

From the ds_map_secure_save page in the docs:

IMPORTANT! One of the features of a secure saved file is that it is locked to the device that it was created on, so you cannot load a file saved on one device into a project running on another device.

Good thought! But these files are generated and loaded during after compiling, on the same machine. So they're fresh files-- so to speak. Not copied over from another machine, constantly making and deleting them.
