My Newbish Game

I'm making a game where the user is prompted to select a character then select some starting coordinates and use the WSAD keys to move it around. Here is my code thus far (note it is not complete)

code:

% The Moving Program

%%%%%%%%%%%%%%%%%%%%%%%
%      Variables      %
%%%%%%%%%%%%%%%%%%%%%%%

var moveChar:string (1)

var dirSel:string (1)

var winStatus:int:=Window.Open ("fullscreen")

var yesOrNo:string (1)

var xStart:int
var yStart:int

var anyKey:string (1)

%%%%%%%%%%%%%%%%%%%%%%%
%      Procedures     %
%%%%%%%%%%%%%%%%%%%%%%%

procedure moveUp
 if xStart=1
  then sound (1000,100)
 elsif xStart=maxrow
  then sound (1000,100)
 end if
 xStart:= xStart+1
end moveUp

%procedure moveDown

%procedure moveLeft

%procedure moveRight

%%%%%%%%%%%%%%%%%%%%%%%
%       Program       %
%%%%%%%%%%%%%%%%%%%%%%%

loop

put "There are ",maxrow," rows on this screen."
put "There are ",maxcol," columns on this screen."
put ""
put "You can chose a character and move it anywhere in these boundaries with this program."
put ""
put "Select You Character :: "..
 getch (moveChar)
cls

loop
put "You have chosen to use ",moveChar,"."
put ""
put "Is this correct? (Y/N) :: "..
 getch (yesOrNo)
  if yesOrNo = "y" then
   exit
  elsif yesOrNo = "n" then
   exit
  else put ""
       put "Invalid Input"
  end if
 
  cls
  end loop
 if yesOrNo = "y"
  then exit
 end if
 cls
end loop

loop
cls
 put "Choose the starting coordinates for your character"
 put ""
  loop
   put "Choose an x value between 1 and ",maxrow,"."
    get xStart
     if xStart > maxrow then
      put "Value is too high"
      put ""
     elsif xStart < 1 then
      put "Value is too low"
      put ""
     else exit
     end if
  end loop
  loop
 put ""
 put "Choose a y value between 1 and ",maxcol,"."
  get yStart
       if yStart > maxcol then
      put "Value is too high"
      put ""
     elsif yStart < 1 then
      put "Value is too low"
      put ""
     else exit
     end if
  end loop
  exit
end loop

setscreen ("nocursor")
cls

put ""
put " CONTROLS"
put " ==============="
put " W - Move Up"
put " S - Move Down"
put " A - Move Left"
put " D - Move Right"
put ""
put " X - Quit"
put ""
put " Press Any Key To Start The Game..."
 getch (anyKey)
 
cls

loop
 cls
  locate (xStart,yStart)
  put moveChar
 getch (dirSel)
  if dirSel = "w"
   then moveUp
  elsif dirSel = "s"
   then moveDown
  elsif dirSel = "a"
   then moveLeft
  elsif dirSel = "d"
   then moveRight
  elsif dirSel = "x"
   then exit
end loop


If you will examine the code at the very bottom

code:

  if dirSel = "w"
   then moveUp
  elsif dirSel = "s"
   then moveDown
  elsif dirSel = "a"
   then moveLeft
  elsif dirSel = "d"
   then moveRight


You will see I have used if statements and depending on input, I am trying to call a procedure. when I try to run my program, it says that moveUp and all the others are not declared, well. At the top I declared moveUp and I'm stuck.

How do you call a procedure after a THEN statement?

you'd have to read a tutorial on procedures and fuctions, it might help out with examples.

a quick guess is that procedures need to have parameters, even if you dont pass any values to it. Such as
code:

procedure something()
put "blah"
end something


notice that () in the procedure name. You might need to have it. Check tutorial for examples, its the best way to find errors - compare to working code

no, you dont need to do that in turing (ur prob thinking of c++)
you can have something like
code:

procedure move
put "Hello"
end move

ne way the the only errors i get r concerning the other move procs not moveUp

also turing may have caught this but

code:
procedure moveUp

if xStart=1
  then sound (1000,100)
elsif xStart=maxrow
  then sound (1000,100)
end if


is never ended

it shoudl be more like

code:

procedure moveUp

if xStart=1
  then sound (1000,100)
elsif xStart=maxrow
  then sound (1000,100)
end if
end moveUp

[/code]

ah yes... since you commented other procedures out, turing doesnt know what to call.

also it seems you dont have "end if" in there

I know some are comments but moveUp isn't so it should work. my question was just in case you are illiterate, how do i call a procedure after a then statement?

just put its name there Confused

code:

procedure hi
put "hi"
end hi

hi %<- this calls the procedure

think of it this way... if it worked wit one procedure (moveUp) wouldnt it click that doin the same thing would work wit all other procedures Confused

*note* : its times like this i agree wit tony's sig

look

heres an example.

I have a bunch of ifs/elsifs

if this = that
then run
if black = white
then jump[/b
end if

notice the big red bolded ones? yeah, they are procedure name's we'll say, the procedures are all written and it doesn't matter what they say cuz thats not the point.

notice how i put the procedure name after [b]then?

well it won't run the procedur evn if the if's imply it should.
