LÖVR

LÖVR lets you make VR games with Lua!

Example

In a folder called myGame, create a file called main.lua with this in it:

function lovr.update(dt)
  t = (t or 0) + dt
end

function lovr.draw(eye)
  lovr.graphics.setColor(80, 0, 160)
  lovr.graphics.translate(0, 1, -1)
  lovr.graphics.rotate(t * 2, .70, .70, 0)
  lovr.graphics.translate(0, -1, 1)
  lovr.graphics.cube(0, 1, -1, 1)
end

Drag the myGame folder onto a shortcut to lovr.exe. You should see a spinning purple cube! See instructions below on compiling lovr.exe.

Dependencies

LuaJIT
GLFW (3.2+) and OpenGL (3.2+)
assimp
SteamVR (OpenVR)

Supported Hardware

HTC Vive

Support for other hardware will happen eventually.

Compiling

Windows (CMake)

Install lovr-deps:

cd lovr
git clone --recursive https://github.com/bjornbytes/lovr-deps deps

Next, build using the CMake GUI or using the CMake command line.

mkdir build
cd build
cmake ..

This should output a Visual Studio solution, which can be built using Visual Studio. Or you can just build it with CMake:

cmake --build .

The executable will then exist at /path/to/lovr/build/Debug/lovr.exe. The recommended way to create and run a game from this point is:

Create a shortcut to the lovr.exe executable somewhere convenient.
Create a folder for your game: MySuperAwesomeGame.
Create a main.lua file in the folder and put your code in there.
Drag the MySuperAwesomeGame folder onto the shortcut to lovr.exe.

OSX (tup)

Used for development, not generally recommended.

One-time setup:

cd lovr
git clone git@github.com:ValveSoftware/openvr ..
export DYLD_LIBRARY_PATH=`pwd`/../openvr/lib/osx32
brew install assimp glfw3 luajit

Compiling:

tup

Running a game:

$ ./lovr /path/to/game
