unitytechnologies / minecraftecs

This is a Workshop Project that made for a User group talk in Taiwan, It's about how to create a Minecraft like environment with huge number of blocks using ECS

MinecraftECS

Please note that Minecraft is a 3D sandbox game developed by Mojang Studios(Microsoft) where players interact with a fully modifiable three-dimensional environment made of blocks and entities. And this project is a tutorial that shows how to make a game like Minecraft using Unity and DOTS technologies.

[2023/02/19] Upgrade: Unity Version:2022.2.7f1 Render Path: URP Forward+ DOTS Version to 1.0.0 pre-44

Fixed Translation API to LocalTransform

Unity Version: 2022.2.0b10

It's been 4 years since last time I update this project. and I hope you can learn some Unity DOTS technologies from it! Enjoy it!

minecraftecs's Issues

Why DestroySystem using Three-dimensional loop for visit a block ?

Can't it be done in one loop?

搞个发布版(Releases)行吗

Can't run the project in any unity version

cause entities version has update to several version, will you update the project to unity 2019.3 or newer version? i can't running this project in unity 2018.4, and update the packages still can't run success.

Legal Stuff

It might be a good idea to add a license to the project. Especially if you start accepting community contributions. Something like the Unlicense would work well I think.

"Minecraft" is a register trademark owned by Microsoft. So it might be a good idea to rename the project to something more generic like "VoxelSandboxECS" just to be safe.

Textures may also be a copyright issue if they are from the actual game, but these could be easily replaced with some free open source textures by Kenny, which I'd be happy to do for you.

Community Contributions?

Are you open to community contributed pull requests? I think I can help improve the project some if you like.
