  • open-project-1

    Unity Open Project #1: Chop Chop

    Project mention: Unity will quietly waive fees if developers switch to its ad monetisation | news.ycombinator.com | 2023-09-14

    I wish they'd go the way of Epic and make an actual game with their engine. They've tried a few times and given up each time. It's pretty embarrassing when they've done things like released a fully featured multiplayer FPS demo that doesn't actually work out of the box and has a custom editor tool manager, custom scene loader, and custom networking layer that were never merged into mainline unity. Meanwhile they still have no official stable networking module. The old functional one was sunset and the new ones are still in beta.


    > This project is based on Unity 2018.3

    > NOTE: Due to a bug in Unity 2018.3, you have to take the following step right after the initial import: 1 Search for Firstperson_Projection in the Project search field. Select the 4 shaders, right click and reimport them. 2 If you have script compile errors related to entities, you need to remove and re-install the entities package.

    > One day soon we will remove this note and there will be cake.

    > Once the editor is ready, open the Project Tools Window by navigating to FPS Sample > Windows > Project tools.

    > Keep this window docked as you will use it a lot. From here you can open the levels, build assetbundles and build standalone players.


    > Note: As of December 2021, Open Projects and Chop Chop are not in development anymore.
