Action! Programming for the Atari 8-bit Computer - Part 21 - Antic Mode 4 Part 3

The 21st in a series of videos in programming in Action! for the Atari 8-bit computers.
More on Antic Mode 4. I finish re-writing the rest of the code to get the multi-color dog running around the screen dropping his multicolor messes. Also talk about refactoring code and code re-use.
Code for my videos are at my GitHub at GitHub.com/Davi...

Awesome work David. Thank for your work.

Please continue your series! I’d love to see a jump to assembly language as well. ❤

Good series David 👍 does action have the equivalent of a ror instruction ?

[@davidarlington1206]

No, Action! has RSH which I use a lot to shift bits. ROR does the same thing but rotates the Carry flag into the high bit and rotates the former low bit to the Carry flag. Since Action! can't generally access registers, you'd need to include a block of machine code to make use of it.
