Experience using Emscripten to convert C/C++ projects to Web #230

Open Trilarion opened 4 years ago

Trilarion commented 4 years ago

In a recent conversation, the idea of converting C/C++ projects to the Web platform using Emscripten (https://en.wikipedia.org/wiki/Emscripten, https://emscripten.org/) was mentioned. This sounds like it could be a very useful approach of distributing such projects.

Questions:

How easy is it really?
Are there any specific requirements on the C/C++ projects (which third party dependencies are supported)?
What needs to be adapted (like the UI)?
How is the performance?

Thanks for the links. It seems to be possible but not right out of the box and for every game yet. It's interesting though and if somebody does more with open source games, I would be happy to hear about it.
