The lua script (for BizHawk 2.8)
Disclaimer that I'm not a programmer, so the code is not well-optimized. It is commented, however, so please check it out at the download link above to get the full idea of how it works. Below is a summary.
The lua script essentially reads the graphic elements in a 9x10 to 6x10 rectangle (depending on the closeness of the pipe spawns) ahead of the player, and interprets where the gap between the next set of pipes is based on where it detects the top/bottom pipe lip graphics. Based on this interpretation, the script will press the button if the bird falls below a certain y position to align it with the gap and hopefully pass through.
There is one problem with the script however, and is why only about 99% of the TAS was generated from it. The script sometimes has trouble threading the needle when the gap between consecutive pipes shifts down by two rows, and when the pipes are spawning closest together. Since correcting this problem didn't seem easy with the way the script was currently set up, I decided to just manually correct every instance the bird crashed into a pipe. I don't know if this decision ended up being faster TAS creation time in the long run, but here we are.
