Tiny Code Christmas - Day 9⌗

Welcome to Day 9 of Tiny Code Christmas! If you’re just joining us don’t forget to check out the overview, and start at Day 1! You can start whenever you like, there are no deadlines!

Today we’re look at a classic shadebob effect. Combine some nice motion patterns with an additive drawing effect and master today’s challenge. For TIC-80 users we’ll also be taking a look at the poke function and how can use it to set our pixels and our palettes.

Liquidream has helpfully provided a PICO-8 palette that is suitable for gradient usage, compressed using 2DArray’s “Palette Maker” to 25 chars:

The first challenge is to get an animated shadebob effect on the screen! Use sin and cos to create an animated shadebob, you’ll have to do the additive bit yourself!

You can check out our Day 9 video above for an overview on this type of effect.
