TODO rewrite this into something more consumable

The below is a copy-pasta from my mind-garden. I’d like to rewrite it into a proper post covering jump-impl resources for 2d platformers - stay tuned!

Ideally we’ll work up to an example repo for this + a twitch and youtube video companion.

Seems simple, unfortunately it’s not.

In my next jump implementation, I’m going to do that height-as-input style, and be sure to include variability (small/large jumps). That control should make for a better game-feel, and support more flexible level design. (Update: I did it! see ‘Implementation’ below)

beehive’s platformer (sidescroller) machine now supports adjustable jump based on rise/fall time and height

The jump/fall code is part of a state machine:

There’s other stuff in there, but it’s fairly flexible if you’re cozy in the beehive state machines.
