Help With Shooting

-----------------------------------

I can only shoot 1 bullet...... then i can shoot another only when the bullet i shot before comes off the screen...I need to know how to shoot bullets continuously.

var x, x2, y, y2 : int := 200 
var shot : boolean := false 
var bulletx, bullety : int := 0 
var input : array char of boolean 
setscreen ("offscreenonly") 
loop 
    colorback (black) 
    cls 
     drawfillbox (50, 110, 40, 280, white) 
     drawfillbox (590, 110, 600, 280, white) 
     drawfillbox (490, 0, 500, 25, white) 
     drawfillbox (490, 375, 500, maxy, white) 
     drawfillbox (125, 375, 135, maxy, white) 
     drawfillbox (125, 0, 135, 25, white) 
     drawfilloval (320, 190, 50, 50, white) 
    drawfilloval (450, 200, 6, 6, brightblue) 
    drawfilloval (x, y, 6, 6, brightred) 
    Input.KeyDown (input) 
    if input (KEY_UP_ARROW) then 
        y := y + 5 
    elsif input (KEY_DOWN_ARROW) then 
        y := y - 5 
    elsif input (KEY_LEFT_ARROW) then 
        x := x - 5 
    elsif input (KEY_RIGHT_ARROW) then 
        x := x + 5 
    elsif input (KEY_SHIFT) and shot = false then 
        shot := true 
        bulletx := x + 5 
        bullety := y 
    end if 
    if bulletx < maxx and shot then 
        bulletx += 5 
        drawline (bulletx, bullety, bulletx + 10, bullety, white) 
    elsif bulletx >= maxx then 
        shot := false 
    end if 
    View.Update 
    delay (10) 
end loop

i think processes would be the answer here, although they are kinda crappy and they slow down ur program its probibly the way to go

First of all, use code tags. [code]Put your code here.[/code]

Ok, now there are several of these types of programs here.  Read through this one that's being worked on now, and learn from it.

Here's a hint, if you want to shoot more than 1 bullet, it's easiest to put it into an array.

Any please quit posting about this topic.  You've made about 3 already, and there's no real difference in them.

EDIT - Token: Most definately not, never use process' for something like that, there's always a way around doing more than one thing at the same time.
