How to move and shoot at the same time

[NeutronX]

I am making a game that required a car to shoot rockets but I want it to drive at the same time and not just stop. How can I move and shoot at the same time?

Here's the code:

code:

var bullety : int var bulletx : int bulletx := 00 bullety := 200 var bullet : int var chars : array char of boolean var x, y, x1, y1 : int var Shooting : boolean := false x := 00 y := 200 View.Set ("offscreenonly")     var pic1 : int := Pic.FileNew ("bullet.bmp")     var sprite1 : int := Sprite.New (pic1)     var pic2 : int := Pic.FileNew ("coolcar2.bmp")     var sprite2 : int := Sprite.New (pic2) loop     Sprite.Show(sprite2)     Sprite.SetPosition (sprite2, x, y,true)         Input.KeyDown (chars)     if chars (KEY_RIGHT_ARROW) then         x := x + 5         bulletx := bulletx + 5         if x > maxx then             x := x- 5             bulletx := bulletx - 5         end if     end if     if chars (KEY_LEFT_ARROW) or chars ('s') then         x := x - 5         bulletx := bulletx - 5         if x < 0 then             x := x + 5             bulletx := bulletx + 5         end if             end if         if chars (' ') then         for i: x .. 690 by 10                    Sprite.Show (sprite1)         Sprite.SetPosition (sprite1, i, y, true)                 delay (1)         View.Update         Sprite.Show(sprite2)         Sprite.SetPosition (sprite2, x, y,true)                end for         end if         if bulletx > 640 then             Shooting := false             bulletx := -20         end if          View.Update end loop

PLZ HELP!

[HeavenAgain]

you'll better edit this code before a mod comes here and go crazy again (they are on a roll these days ), use code tag!

code:

[code]blah blah blah[/code]

and i think this have something to do with Input.KeyDown

but i could be wrong

Edit: oh and if left arrow key is pressed and s is pressed, that if statement should be and instead of or

Your code needs some revamping...

You currently have it so that the player has to HOLD arrow keys to control the location of a bullet.

If I hold RIGHT ARROW for 2 seconds and let go, the bullet will stop moving.

You also for some reason have it setup so that you are always on the location of the bullet because if I hold right, the x cord of the bullet will increase by 5 but so will the location of the car in this case.

What you should do is go through your code line by line and make sure what you want it to do makes sense.

Use processes!
You probably have heard of procedures; processes are the same except they run at the same time as other processes. This would allow you to have a process for shooting and another for driving run concurrently. Look in on processes in F10.

I suggest you not use processes and look into Input.KeyDown, processes are not usefull is this situation

[Zampano]

You know better than I the best method. If there is an efficient way to do it with just Input.KeyDown (more complex visuals are difficult in a loop that relies on the activation of an if) then you should do that instead of using processes.
Processes may be convenient sometimes, but they are troublesome even more often . . .
