Update February 2023
Added 2023-03-01 01:57:34 +0000 UTCHi, this month I started by doing all the more boring things involved in releasing a 4D Toys Update, such as making and uploading iOS builds, writing blog posts, etc... I only have to click a couple buttons to release the update, but I needed a break.
So for a couple weeks I fixed all the remaining small issues with the collision detection code, which still had like a dozen small but important items on it. I thought it would feel nice to get done with it.
To be honest, I thought I understood collision detection pretty well when I started the game, but I still had a lot to learn. That made it extra "interesting" because the 4D adds other difficulties on top of that, obviously.
Initially the Miegakure collision detection was all based on a grid. Then because of 4D Toys I wrote other routines such as sphere/tetrahedral mesh collision, and I imported them into Miegakure, which allowed complex objects to be present in Miegakure. Then at the end of last year I imported the improvements I had made to the collision in Miegakure back again to 4D Toys, ahah. In the process I found and fixed a pretty important bug, so that was a nice bonus.
