This isn't a request for completely new NPC codes, but rather, to adapt some old ones so they fit modern standards and become easier to use. Specifically, these codes by Valtteri:

Some extra specifics: For the Angry Sun, I want the inactive and active versions to be merged into one NPC. Also, whoever does this might as well code the moon from Super Mario Maker 2 as well since it uses the same AI. In terms of the Flame Chomp, not really anything I need to mention asides from the fact that it uses the flying enemy AI (which is an NPC code option anyways, so that's not even a problem.)
