Question 1

How to set up a basic VR scene in LÖVR?

Accepted Answer

Create a `main.lua` file with a `lovr.draw` function, use commands like `pass:text` or `pass:cube` for rendering, and drag the file onto the LÖVR executable. The README provides simple examples, such as displaying 'Hello World' or a spinning cube with minimal code.

Question 2

LÖVR vs Unity for VR development?

Accepted Answer

LÖVR is lighter and Lua-based, ideal for quick prototypes and Lua enthusiasts, offering minimal setup and high performance. Unity has a larger ecosystem, advanced tools, and C# support but comes with more overhead and complexity. Choose LÖVR for simplicity and speed, Unity for feature-rich projects.

Question 3

Does LÖVR support hand tracking?

Accepted Answer

Yes, LÖVR supports hand tracking through the `lovr.headset.getHands()` function, as shown in the README example for rendering spheres at hand positions. It integrates with VR hardware like Oculus and Vive for immersive input.

Question 4

Can I use LÖVR for desktop games without VR?

Accepted Answer

Yes, LÖVR includes a VR simulator mode, allowing development and testing without VR hardware. You can build traditional 3D applications, though it's optimized for VR, so non-VR use might lack some desktop-specific features.

Question 5

How to import 3D models into LÖVR?

Accepted Answer

Use `lovr.graphics.newModel('model.gltf')` to load models in glTF or OBJ formats, then draw them in the `lovr.draw` function. The README shows an example with a model called 'model.gltf', and documentation covers additional formats like skeletal animation.

Question 6

Is LuaJIT required for LÖVR, or can I use standard Lua?

Accepted Answer

LÖVR is optimized with LuaJIT for performance, as mentioned in the README for fast execution. While it might work with standard Lua, LuaJIT is recommended to achieve the high-performance claims, especially for compute-intensive tasks like particle systems.
