Help with multiple bullets

[ha1o]

I'm trying to make a space shooter and I need help getting multiple bullets on the screen at once. This is what I have so far:

code:

View.Set ("graphics: 500, 600, offscreenonly") colorback (black) cls %Draws the spaceship Draw.Line (1, 1, 26, 52, white) Draw.Line (52, 1, 26, 52, white) Draw.Line (1, 1, 52, 1, white) Draw.Fill (26, 2, white, white) var spaceship : int := Pic.New (0, 0, 52, 52) Pic.SetTransparentColor (spaceship, black) cls var shot : int := 0 const SHIP_SPEED := 2 const BULLET_SPEED := 3 %Spaceship var x : int := 330 var y : int := 0 var chars : array char of boolean %Laser var bullet_x : int var bullet_y : int var bullet_y2 : int var chars2 : array char of boolean forward procedure movement procedure shoot     loop         shot := 1         bullet_y += BULLET_SPEED         bullet_y2 += BULLET_SPEED         exit when bullet_y > 700         movement     end loop     shot := 0 end shoot body procedure movement     Input.KeyDown (chars)     Input.KeyDown (chars2)     %Spaceship Movement     if chars (KEY_RIGHT_ARROW) and x <= 445 then         x += SHIP_SPEED     end if     if chars (KEY_LEFT_ARROW) and x >= 1 then         x -= SHIP_SPEED     end if     if chars (KEY_UP_ARROW) and y <= 545 then         y += SHIP_SPEED     end if     if chars (KEY_DOWN_ARROW) and y >= 1 then         y -= SHIP_SPEED     end if     if chars2 (' ') and shot = 0 then         bullet_x := x         bullet_y := y         bullet_y2 := y + 20         shoot     end if     if shot = 1 then         Draw.ThickLine (bullet_x + 26, bullet_y + 55, bullet_x + 26, bullet_y2 + 55, 5, brightred)     end if     Pic.Draw (spaceship, x, y, picMerge)     View.Update     delay (1)     cls end movement loop     movement end loop

Why Do you Have 2 Input.KeyDowns? Far as I know you only need to use it once in the loop. As for the bullets and multiple of them consider either this: Arrays(probably the easiest) and/or a link list. For arrays you can check here http://www.compsci.ca/v3/viewtopic.php?t=14333 for a tut on how it works and when it should be used. For Linklist i don't know if a tutorial is up for that but you can try Googling it.

1) You only need one input keydown... No point in 2
2) Flexible arrays would be your best bet when it comes to creating and removing objects because it A) Won't lag Turing as much, B) Allows you to create as many bullets as you want as opposed to regular arrays which would only allow you to create a set amount of bullets right from start and any time you create more than that, Turing will crash.

Flexible Arrays is what you should learn for this as it's most effective for this type of idea you want. If you don't already know them, try to learn regular arrays first considering flexible arrays aren't all that much more difficult! Good luck!
