Thank you both. Funnily enough, I did tinker with TIME a bit later on, but I was still getting the same result. I looked at a couple of games from the archive for ideas on implementation - Professor McBrolly, and BlocBusta. They both utilise TIME, the former achives a consistent countdown, while BlocBusta has an air supply, which appears to decrement in a consistent fashion, but it does use a tick counter, rather than explicitly refer to TIME.ChrisB wrote: ↑Tue Nov 23, 2021 7:36 am What Richard said. Having played with the code when the diver moves there's much more time taken with unplot/plot etc. Than when the fish just move. This might be alleviated with some sprite code. Alternatively why not tie the oxygen to TIME which will decrement at a constant rate.
I've had to leave the code for a while, as I have a lot going on the rest of this month, which is annoying for me personally. I'll just have to grit my teeth!
