This guide describes how to use Steam Proton to play and run Windows games on your Linux computer. Some games may not work or may break because Steam Proton is still at a very early stage.

1. Activating Steam Proton for Linux:
Proton is integrated into the Steam Client with "Steam Play." To activate proton, go into your steam client and click on Steam in the upper right corner. Then click on settings to open a new window. From here, click on the Steam Play button at the bottom of the panel. Click "Enable Steam Play for Supported Titles."

Alternatively: Go to Steam > Settings > Steam Play and turn on the "Enable Steam Play for Supported Titles" option.

Valve has tested and fixed some Steam titles and you will now be able to play most of them. However, if you want to go further and play titles that even Valve hasn't tested, toggle the "Enable Steam Play for all titles" option.

2. Choose a version
You should use the Steam Proton version recommended by Steam: 3.7-8. This is the most stable version of Steam Proton at the moment.

3. Restart your Steam
After you have successfully activated Steam Proton, click "OK" and Steam will ask you to restart it for the changes to take effect. Restart it. Your computer will now play all of steam's whitelisted games seamlessly.

4. Launch Stardew Valley on Linux:
Before you can use Steam Proton, you must first download the Stardew Valley Windows game from Steam. When you download Stardew Valley for the first time, you will notice that the download size is slightly larger than the size of the game.
This happens because Steam will download your chosen Steam Proton version with this game as well. After the download is complete, simply click the "Play" button.

GameApi Builder tool allows creation of trailers, game prototypes and even full games using industry standard gltf/glb technology and extensive node graphs.

GameApi Builder is a 3d engine and node graph tool for creating trailers, game prototypes and even full games (with some caveats). With a library of 600 different nodes create full product via scripting language that contains the node graph, including node types and parameters used to tweak the end result. The product is designed for youngsters at the high school level and above. Let your game development story begin with our technology.

Here's a picture how the builder tool looks like, if you use it properly:

Then the game itself will look something like this, while you're editing it via ML nodes:

And run_window node gives you full game display for screenshots, final testing, videos etc:

Then once the game is ready, you can use html_run and save_deploy nodes to make a html5 distribution package:

And there you go, you're ready to see the result:

There you go, got a ALL OK and zip file saved to /home/terop/.gameapi_builder/Downloads/gameapi_deploy.zip...
uncompressing that to your hosting location directory will give you url to the display.php file and then browser should be able to open it. The game works in browser, but very very slowly. The reason is that pthreads and brotli are disabled, so you'll need to practise your web server maintainance skills and setup SharedArrayBuffer support (and https is required) and brotli support. These enable 8 cpus and compression.
