A series of short explainers of various 2d gamedev math concepts, explained with images.
I've tried my hand at 2d game dev "from scratch" (i.e. no frameworks) recently, building games such as safe tea and down the river. Along the way, I had to figure out how to do the math for a lot of 2d concepts / gamedev concepts. I diagram a lot to try and understand what I'm doing. This is my attempt at organizing and sharing the lessons I've learned.
