i have a program - type of asteroids game - in which you can shoot the asteroids. If everytime i press "shoot" i get the number of shots to appear on the screen, but everytime i have to use: g2.fill(shot[a]) instead i want to use a for loop so i can have it draw the amount that was pressed: for (int i =0; i >= shotPressedl; i++) { g2.fill(shot[i] } what i have is: g2.fill(shot[a]) g2.fill(shot[b]) g2.fill(shot[c])... and for ever what happens is that my program wont recognize my for loop or it just wont execute for some reason. Is there a restriction that i cannot use loops in a paint method of an applet? |

i understand, but this statement is always true and it will never run i is always less than the number of shots pressed this is my code which isnt working
for some reason this for loop doesnt seem to be even executing. Could someone please help me thanks |

for (int i = 0; i >= shotPressed; i++) { g2.fill(fire1[i - 1]); } even if this loop executes, it will not follow my instructions... it will not fill the object. Do you know what is wrong. IT FEELS LIKE THE LOOP DOESNT EXECUTE EVEN THOUGH IT MAYBE EXECUTING. I want the loop to execute and run properly atleast once, because when i tell it to run, it just wont work. |
