my program is 

% to set screen
setscreen ("graphics:600,500, position:center;center,nobuttonbar,offscreenonly")
%constants
const rows := 42
const columns := 42
const size := 15
% declare the variables
var bold, italic, underline : boolean
var maze, x, y, c : int
var font1, font2, font3, font4 : int
var text1, text2, text3 : string
var keys : array char of boolean
var counter : int := 0
var startime : int
var timeremaining : int
var timeLowRange : int := 5
var timeHighRange : int := 10
var travelled : array 0 .. columns + 1, 0 .. rows + 1 of boolean
var routes : int := 0
var direction : array 1 .. 4, 1 .. 2 of int    % there are 4 possibilities and 2 different directions
var way : array 1 .. rows* columns, 1 .. columns* rows of boolean 
var lines : int
var x1, y1, x2, y2 : int
 % to initilize the random values
 randint (x, 0, maxx)
 randint (y, 0, maxy)
 randint (c, 0, 255)
 
 % sets the background colour as black
 drawfillbox (0, 0, maxx, maxy, 7)
 
 %assign the font type and the size, for "The Maze"

Re: need helppppppp with my maze ..

-----------------------------------

Fix it into one entire loop, and cut out all the small loops where ever you used the Input.KeyDown.

And only declare it once.


loop
     Input.KeyDown (keys)

%Code
end loop

Re: need helppppppp with my maze ..

-----------------------------------

When i have the chance to use the other machine, I'll send you a PM with an example of Input.KeyDown with character movement.

RE:need helppppppp with my maze ..

-----------------------------------

i know how it works and stuff but when I try this      .............it does something but does not move the oval
Input.KeyDown (keys) 
   put " before if "
        if keys (KEY_UP_ARROW)  then 
        y += 1
         Draw.FillOval (x1,y1, x2, y2, red)
        put " jhgerjkfhsd"
       end if 
        if keys (KEY_LEFT_ARROW)  then 
         x -= 1 
          Draw.FillOval (x1, y1, x2, y2, red)
        end if  
        if keys (KEY_RIGHT_ARROW)  then  
           Draw.FillOval (x1, y1, x2, y2, red)
            y += 1
        end if 
        if keys (KEY_DOWN_ARROW) then 
        y -= 1 
           Draw.FillOval (x1, y1, x2, y2, red)
        end if
 View.Update
 Input.Pause

Re: need helppppppp with my maze ..

-----------------------------------

You are not attempting to redraw the oval after you press the key. Once it is in a loop, and you use View.Update, and no Input.Pause you should be fine.

RE:need helppppppp with my maze ..

-----------------------------------

Re: need helppppppp with my maze ..

-----------------------------------

Here is an example:


View.Set ("offscreenonly")

var keys : array char of boolean
var x, y : int := 100

loop
    Draw.FillOval (x, y, 15, 15, blue)

    Input.KeyDown (keys)
    View.Update

    if keys (KEY_RIGHT_ARROW) then
        x += 1
    elsif keys (KEY_LEFT_ARROW) then
        x -= 1
    end if
    cls
end loop

RE:need helppppppp with my maze ..

-----------------------------------

You didn't initialize x1 and y1 (unless I missed it) You randomize x and y, then declared them again with x2 and y2 later on.
