For the past while I have been trying to come up with a program containing a ball bouncing across a screen, with gravity taken into consideration. This is as far as I've gotten: setscreen ("graphics:vga") const midx := maxx div 2 const midy := maxy div 2 const a := 1 var yy : real var x, y, t : int := 0 for i : 1 .. 28 t := i x += 10 y := maxy - ( (a * t * t) div 2) drawfilloval (x, y, 14, 14, red) delay (30) cls end for const b := 1 for i : 27 .. 40 t := 28 x += 10 y := maxy - ( (b * t* t) div 2) drawfilloval (x, y, 14, 14, red) delay (30) cls end for I was wondering is there was an easier way, or how to continue this, and if anyone knows, how? Thanks Alex alexbarker49@hotmail |

well this is just animation, so you'd have to continue drawing each frame manually... unless you actually design a single function using velocity (as in speed with direction). I made a tutorial about pool game http://danco.no-ip.com/turing/viewtopic.php?t=129, it has to do with balls hitting each other and stuff... See if that helps. Atleast that describes how to use velocity. |
