Example: the autotargeting bullets which worked fine in the first game. They just did not work perfectly in RESHOOT R anymore, because the scrolling not only is much faster than in Reshoot, but it´´ s also varying in speed. Therefore some bullets did not hit the players direction like intended. I needed to implement more math precision and also prepare the targeting code to cope with variable scrolling speed. Took me a whole week to get this just right. But now all the bullets you see head towards the sweet spot of the players ship, no matter what´´ s going on, with full 50 frames / second glory.
Sometimes the precise path calculation also leads to very beautiful looking, curved bullets streams, something you could no´t see on the Amiga too often. Therefore I´m kind of satisfied that I took the time to balance the code.
