Features

Wyvern is far from a feature-usable engine, so don't expect much at the moment.

• Configurable Core Pipeline
  • Currently this entails choosing between SDL or GLFW, and OpenGL or OpenGL ES (and WebGL through Emscripten).
    More options will come in the future as I continue to add better cross-platform support

Planned Features

The code is more what you'd call 'guidelines' than actual rules.

aka these are things that I want to implement, not a timeline

---

• Direct3D and Vulkan Backend
• (Homebrew) Console support, such as Xbox/Xbox 360, PlayStation®3, etc.
  • a large portion of the configurable pipeline in Wyvern is to allow for easy implementation of more involved platforms, although this is not a priority
• Proper Editor (Likely using wxWidgets or Qt), and through that:
  • and through that, SceneGraphs, Prefabs, runtime Materials, and so on.
• Built-in Physics engine, likely Bullet, PhysX, or Havok. Potentially a custom one but unlikely
• More versatile materials and graphics
  • Currently only basic shading exists and Material properties have to be hardcoded in C++

Building

Wyvern uses the free and open-source build tool xmake.
xmake installation guide

Visual Studio Solution

Run build.bat
The Visual Studio solution will be located in build/vsxmake...

Command Line

xmake f -p <platform> -m <mode>

<platform> is windows, linux, or wasm
<mode> is Debug, Release, or Package

xmake

Building WASM

Wyvern supports WASM through SDL and OpenGL ES. Building is done using xmake like normal, but requires a few extra steps.
Emscripten installation guide can be found here

msys2 & mingw64

Installing Dependencies

1. In the msys2 terminal, make sure mingw64 is properly installed

pacman -S --needed base-devel mingw-w64-ucrt-x86_64-toolchain

2. Start mingw64 terminal as administrator

pacman -S mingw-w64-x86_64-xmake

emsdk activate

xmake l detect.sdks.find_emsdk

the path to EMSDK should be printed

where git

INFO: Could not find files for the given pattern(s).

export PATH=$PATH:<path/to/Git/cmd>  

where <path/to/Git/cmd> is the path to your Git installation

xrepo install -v -p wasm libsdl

xrepo install -v -p wasm assimp

Building

in Wyvern root start cmd, then activate emsdk and build xmake like normal

emsdk activate

xmake f -p wasm -m Package

xmake --rebuild

there should now be an html file in game/

emrun game/Wyvern.html
