I am making kinda game on pascal and I have faced a problem - "spaceship" should move when appropriate button is clicked, but you need to click the same button for 5 times. So I think a solution would be to make it think you pressed the same key 5 times while you do it only once, but is it possible to do?

PS

here's the whole code (very little yet) if you can think of a better solution :)


program Bevarde1;
uses Crt;
var x, y: integer;
left, right, up, down: string;

procedure SetKey;
begin
Left := ('a');
Right := ('d');
Up := ('w');
Down := ('s');
end;

procedure DrawMe;
begin;
GoToxy(x+2, y-1);
Write('I');
GoToxy(x, y);
Write('<=M=>');
GoToxy(x+1, y+1);
Write('I I');
end;

procedure PS;
begin
readkey;
ClrScr;
If readkey = left then x := x - 1;
If readkey = right then x := x + 1;
If readkey = up then y := y - 1;
If readkey = down then y := y + 1;
DrawMe;
end;


begin

SetKey;

x := 38;
y := 15;
DrawMe;

while 1 = 1 do PS;

Readln;
end.

What's with the parentheses around the setkey values?

: procedure SetKey;
: begin
: Left := ('a');
: Right := ('d');
: Up := ('w');
: Down := ('s');
: end;

Try this:

   procedure SetKey;
     begin
         Left := 'a';
         Right := 'd';
         Up := 'w';
         Down := 's'
     end;

And then try poking these lowercase keys to see if you get any movement.

That's a good start, if you read through this forum then you'll find lots of examples on this subject. Here's a simple textmode game you could look at: http://www.programmersheaven.com/mb/pasprog/392302/392335/simple-snake-game-and--maze-generator/?S=B10000

Firstly, thanks for replies :)

Ok, so I checked out that sample (the snake game) and I understood approximately nothing... I'm new to programming, you see... Plus - I copied the code to the pascal I use and it seems not to have some functions. Anyway, I took another route, and everything seems OK to me (even though I'm not sure what I did with the imput :D), but I get an error right away after starting the thing. Any help again?

Oh, here's the code:

     ch: char;

       sp := round (random * 64 + 5);

       Write('<=M=>');
       GoToxy(x+1, y+1);
       Write('I I');
     end;

What compiler are you using ? The game, what is all about ? Explain what you're trying to achieve, time permitting will put ya on the right track.

Ok, so firstly I use Free Pascal 0.6.4.

The game is pretty much like this: you control the "spaceship" and destroy objects falling from the top of screen by shooting them. Once object is destroyed, it respawns immediately in the top.

The objects are basically coordinates. If object is not in use, I just set the x value to 1000.

The x and y values refer to the "spaceship"
The x1 and y1 values refer to the bullet
The sx(1-5) and sy(1-5) refers to 5 independant falling objects.

The whole thing I've done firstly checks for imput (even though I'm not sure will it work), then counts all coordinates and finally draws all objects that are in use. All this should repeat every 10 miliseconds.

One more thing - The objects fall in the same speed as bullet moves, so I'll make them to fall once in about ten loops (that would be approximately 100 miliseconds).

PS

I'm making this game not to make it, but to gain experience in such stuff, so in the end I don't really care if I finish it sucessfully :P

OMG. I have control of situation :) no need of help. when I finish the game I'll post it here (if you want, of coure, and if won't face any more problems).

I'm so happy!!!

Download the game here :)

Why don't you post the source instead ? Someone may learn a thing or two...

OK, here's first I found and last versions of it (First one way more simple) :) both of them have an .exe and .pas files, so you can check the source.
