Hi Ben, Do you mean what am I going that merits all this trouble? 😁
I work on my game engine on my spare time, and I am planning on using V8 as the underlying JavaScript engine, However my immediate need is to use it to power the engine UI, which is a separate project. My idea is to create a small SVG Browser Agent that can be put as an OpenGL or Vulkan Overlay in the game engine, using regular JS to drive animations and events in the SVG page. I tried using Electron, but it turned out that you don't embed Electron, Electron embeds you, and in the end I had to hack too many things to get it barely working on Windows and Linux was a no go. So, I figured I might as well give pure v8 a new try (I used to have cmake scripts to build v8 back when it used scons). I noticed there was no v8 package on MSYS2, despite there being one some years ago, so I started working on that, then tried to install v8 on VCPKG and it just wasn't there despite being requested since long ago (https://github.com/microsoft/vcpkg/issues/372), and now here I am 😆. TL;DR: here's the links for my projects: https://github.com/AeonGames/AeonEngine https://github.com/AeonGames/AeonGUI On Thursday, July 16, 2020 at 9:02:48 PM UTC-6, Ben Ernst wrote: > > Rodrigo, what's your project?
