I just learned Godot over the weekend. I am amazed by how easy it was to get something made. I previously had no real game development experience. Within a weekend, I made a functioning game and later even published it and wrote a blog post. Anyone can play it in Chrome right now.

Here's my weekend Godot creation: https://basilrogers.itch.io/learning-godot-2

View on HN

I know no bug reporting here, anyway i got that error :)

"Warning! The following features required to run Godot projects on the Web are missing: Cross Origin Isolation SharedArrayBuffer"

Firefox 107.0.1 and Linux, but same with FreeBSD

I get the same thing, but I've been ignoring it because that can be a rabbit hole. I've seen lots of advice just to get something small published if you want to do game dev, so that's where my priorities have lied in this project. Now that I have something small published, I am comfortable digging a little deeper.

I was just reading about SharedArrayBuffer recently, specifically about supporting Firefox. Lemme see if I can find it in my notes.. Ah yes, it was about ffmpeg.wasm which requires this feature. Apparently this security restriction is coming to Chrome also.

Does not work in Firefox 79+ because SharedArrayBuffer is undefined #106 - https://github.com/ffmpegwasm/ffmpeg.wasm/issues/106

The solution is to add cross-origin headers.
