I made a new file format

Here I talk about the challenges of saving and loading game state along with what I did to solve it.

"You often only think about this late into development" not unless you've been through this problem before!

"Json's crap" - *invents json with a different syntax*

[shadamethyst]

About rewriting the parser on every format change: this is where metaprogramming can come into play. I'm incredibly grateful for libraries like serde in rust that abstract away the need to do this by hand, and you're using C++ so doing that there shouldn't be too hard either

Never trust someone who uses a light theme code editor.

A full game like Gmod's LIDAR mode is something that I have wanted to see for a while, keep up the good work

[zebbaukhagen]

Some very interesting ambient noise behind you!

I thought maybe there would be a psychological horror twist somewhere, but instead I just learned something. It kept me engaged.

But in all seriousness, this is was very informative and I'm thankful I stumbled upon this video!

[Templarfreak]

"always keep your data as simple as you possibly can" cannot understate this, with doing anything programming-related, not even considering saving and loading for a game, this is an extremely important idea

[sr_meia_noite]

I thought "Well, he's going to create a parser for his structs to know how to read/write in binary format, making it efficient in size, reading and writting"

*Proceeds to save information as raw text*

[valueconomy]

Cool idea. I think you could have achieved this with a mixture of binary JSON and distributing those graph files, but great job. I normally am not a fan of when people try and invent new formats, but I understand the value in readability. I just think eventually you realize you can use an existing solution and eliminating you needing to maintain some bespoke format spec, parser, etc.

Keep it up.

so true about thinking late. a similar thing is when you gotta implement an undo system which needs you to change all the mutations into commands x3

[dankmemequeen]

I like the style. The dots make it look satisfying.

[camilleon]

i loved the combination of eerie sound effects and just so many blinding transitions (i am watching from a dark room)

[mom]

This is the most threatening aura I've seen from a video about file formats.

[IzzyMann]

19 seconds in i said to myself " this is interesting!" and you now have a new sub! :) keep it up bro!

[skejeton]

this is really cool looking! will you draw the particles that are occluded or drawing particles through walls is intended?

[_GhostMiner]

Him: creates a new file format.
Me: creates a folder with hundreds of json files to save properties of each level object.

We are not the same.

[hw]

I did too! I renamed my .txt file to a .hw2007 file!

[bob_kazamakis]

This guy should meet the other guy on YouTube that created reflection in C++ for this purpose
