What Hacker News says
6 sourcesTangentially related. I want to play around with Web Assembly just to try to speed up (or perhaps parallelize) my own implementation of the "ray casting" "voxel" algorithm that the author demonstrates from the old Comanche game.
My straight Javascript implementation: https://github.com/EngineersNeedArt/Mooncraft2000
In How I stopped worrying and started loving the AssemblyThe VoxelCanvas.js file (in Javascript, obv.) might be interesting to you as well. Same (raycasting) idea:
https://github.com/EngineersNeedArt/Mooncraft2000
In A Raycaster in BashI was curious too. GP's github is in their profile and it looks like this is what they were talking about:

In MoonOK, so the landing short thing was due to two things
1. I was using Brave, and the voxels for the landing zones seem to be messed up for some reason, with coloured blobs scattered everywhere. I switched to Chrome and the centre is more obvious.
2. As mentioned before, I didn't realise there was a downward facing camera to use.
But the the issue with not being able to close dialog boxes happens for me in both Brave and Chrome. Seems someone else already raised this an issue, same error as me: I looked in the console and found an error, and seems someone else has already raised the same issue: https://github.com/EngineersNeedArt/Mooncraft2000/issues/1
Also looks like there's already a commit that might fix it.
