OmiLAXR (v2)

This is the base package for OmiLAXR holding all core components of the pipeline pattern. Starting from this package you can install further modules (packages) based on your needs.

Just drag and drop the prefab Resources/Prefab/OmiLAXR into your scene.

Compatibility

Because of the less dependencies and modular design of OmiLAXRv2 this framework is compatible with all XR frameworks. It doesnt matter if you use MRTK, VRTK, SteamVR, UnityXR, ... and it doesnt matter what equipment you use.

You can look for existing modules tracking the behaviour you need. The rest can be easily implemented by you own - and we hope you will share it with the community!

The only thing we need to consider are the Unity version. We try to support as much as possible upwards of Unity 2019.4.40f1. You are invited to contribute!

The compatibility was tested on

• Unity 2019.4.40f1 (LTS)
• Unity 2020.3.48f1 (LTS)
• Unity 2021.3.15f1 (LTS)
• Unity 2021.3.45f1 (LTS)
• Unity 2022.3.52f1 (LTS)
• Unity 2023.2.20f1 (no LTS)
• Unity 6000.0.25f1 (LTS)

Please contact us on https://discord.gg/yJgk4ATg if it is not running on your Unity version. We will try to make it possible.

For Developers

To work with this package we recommend to place it somewhere outside your Unity project (if the package gets an own git repository) or in root of your project. Than, you can include the package into your project by going to Window > Package Manager, click on (+) button and finally import the package.json of this project by clicking on Add package from disk.

For production use we recommend to use Add package form git URL or using scoped registries (see below).

2. On demand increase your version number in package.json.
3. Commit and push your changes.
4. Open a terminal.
5. Go to the root of your project.
6. Run npm login and login via browser (or what else you like).
7. Run npm publish --access public.
8. Wait until publication is ready.
