sorry for the dry response i was quite busy at that time but yeah so in GMS2 in the room you use cameras and set the size of the cam to the same size as the zoom or whatever you want, and change the veiwport size :
No worries. The response was still helpful and I appreciate the brevity. The viewport fix is a good workaround (I used it on an update for my latest jam submission), but I’m going to try another resource for true HTML fullscreen. I can let you know how it goes and share the code if you’re interested.
Yes. I think I found what I needed. I just haven’t tested it out yet. I wish it were as simple as clicking the box like it is for Windows and Mac builds, but HTML requires a little more work.
Changing the viewport worked great and was really easy to make my game play larger in browser, but I still want users to have the option of going completely full screen, no matter what size their screen is, same as if they were playing a downloaded version.
