How to make the red dot stop at the edge of the window and not go out.

[puthelloworld]

What is it you are trying to achieve?
I am trying to make a red dot that can move and it stops when it hits the red of the screen.


What is the problem you are having?
I cannot seem to get the red dot to stop when it hits the edge of the window.


Describe what you have tried to solve this problem
<Answer Here> I tried using a if statement but it didnt work. to limit the maxx and maxy.


Post any relevant code (You may choose to attach the file instead of posting the code if it is too long)
<Answer Here> var x : int := 319
var y : int := 199
var w, a, s, d: char
setscreen ("graphics:max;max,")
drawfilloval (x, y, 30, 30, red)
loop
drawbox (0, 0, maxx, maxy, black)
var c : char := getchar
delay (100)
if c = 'w' then
y := y + 10

elsif c = 'a' then
x := x - 10
elsif c = 's' then
y := y - 10
elsif c = 'd' then
x := x + 10
end if
cls
drawfilloval (x, y, 30, 30, red)
end loop

Turing:

var x : int := 319 var y : int := 199 var w, a, s, d: char setscreen ("graphics:max;max,") drawfilloval (x, y, 30, 30, red) loop drawbox (0, 0, maxx, maxy, black) var c : char := getchar     delay (100)     if c = 'w' then         y := y + 10             elsif c = 'a' then         x := x - 10     elsif c = 's' then         y := y - 10     elsif c = 'd' then         x := x + 10     end if     cls     drawfilloval (x, y, 30, 30, red) end loop

Please specify what version of Turing you are using
<Answer Here> 4.41

Can we see the if statement? If you deleted it, try writing it again -- that is the correct approach. If you run into problems with it not working as you expect, post your updated code here.
