For almost a year now I have maintained the GameMaker: HTML Extension, I’m very excited to say that it is now available from the GameMaker Marketplace under “GMH: Canvas Companion”.
Wait a second, does this now mean that it costs money? Nope! As promised I have kept the extension 100% free and the source code is still available on GitHub if you are into that sort of thing.
So what does it do? Canvas Companion allows you to add snippets of HTML code (Such as a YouTube video) directly into your project without ever leaving GameMaker.
