A project which took its humble beginnings as yet another basic wireframe 3D Engine in 13 Apr 2019, concluded in 1 Aug 2021, shared on 19 Apr 2024. This was roughly the final state of the project(not including later experiments which continued up until 2022). I'm proud of how it turned out, and the memories made with this project. I'm no longer proud of the "3D Graphics and Scratch" group. I wished things were better there.

I expected to get a good enough 3D engine working by 2023. Here I am still dragging away at blocks ahaha. I think I'm close though. Its quite far from what it used to be. The dream has remained though: make a meaningful, but absolutely groundbreaking game on Scratch, friendly and playable for all ages.

But this project isn't quite even a game. It's totally incomplete.

I'm sharing this old project since it was kind of a task overdue, and now I feel like sharing it now as opposed to never doing so. It contains a good list of resources below which I kind of forgot to ever share.

Yes, it contains a gun, but there is no violence or destruction. I hope it's all fine. If not, I think I'll be alright with whatever reasonable consequences, if there are any. After all, its not really the main focus of my game engine development.

A BIT OF THANKS:
No simple words can fully describe the gratitude I hold for those who supported this project. This is especially true with the very early supporters, even if they perhaps no longer follow this development project as much as they used to. Good memories :)
