Damn it's been a ride to see GMS grow so much in just 2 years.

Gamemaker hiring Matharoo for tutorials was one of their best decisions!

Rollback multiplayer is huge! I hope this comes to other platform targets soon.

Is this feature going to be available outside of just GX Games? Like adding it to a game I have on Steam?

Hi, I am receiving this Exception thrown, see JavaScript console error when running the game in my Opera GX browser, how to fix that?

[starsword]

Hey, I'm following the instructions, but when putting the game into Online, the players don't appear what-so-ever, but on offline, they do, any ideas of whats going on?

This new Multiplayer system has a lot of potential! I switched from GameMaker to Unity a couple of years ago. But since GMS2.3, GameMaker looks like it’s becoming a real promising option for modern 2D games. Especially now because of these new Multiplayer functionalities. My inner child is happy to see that I could return to GameMaker in the near future. A lot of love to the GM Team! 🌟

I'm getting an error when starting up the game in GX for the first time. At the end of "Online Multiplayer" and beginning of the "Invite Friends" section of the video. The game loads up and gives me the error "Exception thrown, see Javascript console". Anyone know what may be causing this? Or can lead me in the right direction? Any thing helps!

There is no share link option for me, when starting the game, just open QR Code and the phone does not get access for the page.

Does anyone know why the 'Copy Share URL' button is not appearing for me?

[Underrated_Games]

It says variable unassigned player is reference what do I do

[hothead]

Thank you for this tutorial mate! This really helps!

Could you do a video dedicated to servers? Like, how to support an online game? Or is that not something you are familiar with?

[CapuccinoMachine]

"Copy Share URL" does not appear for me. Saw people on the forum with similar issues, but none solved. What do?

I really wish there was tutorial videos for advanced features that didn't go through -everything-. If you're here for multiplayer, you should really already know that "input left makes x go lower". Keep that for a "simple controls" tutorial. Dive into the concept and philosophy of how the multiplayer system works head on, make me understand what I didn't understand before.

Im getting the 403 forbidden error when launching my game, how can I fix this ? wont even let me download opera gx. Is a vpm the only fix? If so will that affect my multiplayer game?

[memefordays]

When i start the game it says error in action number 1 of Create Event for object obj_player:

[abdullaalrashidi]

I followed everything, however . It doesn't show the other player :/ or make me enter a game. I did set the default region too but still nothing worked

[monsterclaws]

I have obj_player_red and obj_player_blue so how to make second player?

GXC Upload failed
Status code from server : 400 - BadRequest
