another shooting program
i am helping a friend out and hav a bug.
the way its supposed to work is to move the bullets up if they arent to negative 10 in pixels. if they are, then the plane can use it when the mouse is clicked. when i comment out
if (bulletsPlaced =true)
{
for (int i = 0; i < maxBullets; i++)
bufferGraphics.drawImage(myBullets[i],20,myYPositions[i],6,6,this);
bulletsPlaced =false;
}
then the bug doesnt rlly happen.
but if i dont then it puts one bullet at the tip of the plane and then shoots all the others 20 pixels for the x and the same y as that one bullet and then shoots them all up to the top of the screen then does it over and over and over agian.
how can i get it to wer when i click mor than once it fires mor than one bullet and the bullets move?
