Hi Folks,
Here is the optimised Fish2_bas program, featuring 3 chasing sharks : Press the space bar for full hectic speed...
Array space has been greatly reduced, and the swiming smoothed, and may be even better with different-hidden face treatment :
There is no XORing, the fish are rubbed out using background colour, giving a slight strobe pulsation.
QPC2 seems to have ample spare capacity to allow for far more objects in future prototypes ! Steve.
