This is such a great tutorial, you explained from start to finish. I really wish there was a tutorial on this for the Unreal engine GGPO plug-in

I think you should show this in godot con coming this July

Would you mind updating, or pointing me toward a more updated walk through? As far as I can tell. You're the only person out here explaining GGPO. Much appreciated, dude. I have a hard time learning from text books.

this is awesome! ill definately be using this in some of my own projects!

incredible stuff. looking at your tutorial base to analyze it myself rn, will probably have to rewatch both tutorials too. what project types do you think this wouldn't work well on?

[happyburgerman]

Thank you, I've been looking for something like this for so long. What would you do if you wanted to pass in multiple inputs for a player, like one for the joystick and another for a button?

[MenacingMecha]

Could you quickly go over the differences between your source code for the godot_ggpo module and the FlutterTal one? Don't think you say in the vid

Might be worth making an actual fork on GitHub, also

I made some small mistakes in the project folder that I have already fixed in the source repo. An example of this would be me using the addplayer function 3 times in main.gd instead of 2 as shown in the video. So if you got confused by that just letting you it's fixed.You also might have to disable sync logs because that creates a huge folder full of 1kb logs of nothing. Ok now I can go to be cya guys.

Hey, i can't seem to get the exported project to work. It works fine when i run it from debug mode in godot but when i export the project and try to run the exe i get this error.
