Shoot multiple times

[turinghelp123]

What is it you are trying to achieve?
<Make the program shoot multiple times>


What is the problem you are having?
<You can only shoot once then you have to wait till the bullet disappears to shoot again>


Describe what you have tried to solve this problem
<I've been trying to solve this for about 1 hour, and I've been having no luck>


Post any relevant code (You may choose to attach the file instead of posting the code if it is too long)

Turing:

< View.Set ("offscreenonly") var chars : array char of boolean var x, y, bullety, bulletx : int := 100 var shot : int := 0 forward proc movement proc shoot     loop         shot := 1         bullety += 1         exit when bullety + 20 > maxy         movement     end loop     shot := 0 end shoot body proc movement     Input.KeyDown (chars)     if chars (KEY_UP_ARROW) and y + 64 < maxy then         y := y + 1     elsif chars (KEY_DOWN_ARROW) and y > 0 then         y := y - 1     elsif chars (KEY_LEFT_ARROW) and x > 0 then         x := x - 1     elsif chars (KEY_RIGHT_ARROW) and x + 64 < maxx then         x := x + 1     end if     if chars (KEY_CTRL) and shot = 0 then         bullety := y         bulletx := x         shoot     end if     cls     if shot = 1 then         drawoval (bulletx + 35, bullety - 1, 10, 10, 0)         drawoval (bulletx + 35, bullety, 10, 10, 7)         drawoval (bulletx - 35, bullety - 1, 10, 10, 0)         drawoval (bulletx - 35, bullety, 10, 10, 7)     end if     drawfilloval (x, y, 20, 20, 7)     View.Update end movement loop     movement end loop >

Please specify what version of Turing you are using
<4.1>

If you want to keep track of several things of the same type, you should look into arrays and records. Here's the Turing Walkthrough links:

What do you mean? How does this help shooting multiple times?

Right now you have only bullety. You want bullety_1, bullety_2, ..., etc. An array will let you group those related variables together, for much easier use.

Thanks tony, I just looked at arrays but I'm having trouble applying it to my program
