ok i can make a ball move easily

code:

var x,y:int x:=200 y:=100 loop drawfilloval(x,y,20,20,7) delay(20) drawfilloval(x,y,20,20,0) x:=x+2 end loop

what ever..he ball movs but when i do a square, it just extends and gets bigger...how do i make it so the whole square moves and not just get bigger?

Use cls to clear the screen every time it is executed.
So here's your current code improved using cls:

code:

var x, y : int x := 200 y := 100 loop     cls     drawfilloval (x, y, 20, 20, 7)     x += 2 %this is the same as x := x + 2     delay (20) end loop

Now, I believe the problem with your box code is that you are mixing up the parameters. They are:

Quote:

drawfillbox (x1, y1, x2, y2, Color : int)

As on a Cartesian plane.

Also, indent your code properly in the future.

ok i got the saqure to move fine down the screen, i wana do it so if the mouse touchs any pixel of the square, the game wil say you lose, shud i use mousewhere? and how cuz the squae is moving

[Flikerator]

Use Mouse.Where, and look up whatdotcolor in the help file.

exit when whatdotcolor (Mx,My) = boxcolor

or

exit when Mx > ### and Mx < ### and My...

Mx and My are the mouse coordinates.

After the loop have the "You've been pwned"

[Cervantes]

Let's avoid whatdotcolour, shall we? It's a bad approach to collision detection, especially for newbies.

Go with the second approach:

Turing:

% let mx = mouse x % let my = my % let blockx = x value for left side of block % let blockwidth = width of block % let blocky = y value for bottom of block % let blockheight = height of block if mx >= blockx & mx <= blockx + blockwidth & my >= blocky & my <= blocky + blockheight then     % collision! end if

If you have Turing >= 4.05 then, this can be achieved more simply by

code:

Math.Distance(x1, y1, x2, y2)

which is the same thing as the distance formula in the cartesian plane:

code:

distance = sqrt ( (y2-y1)^2 + (x2-x1)^2 )

All you need to do is check if the distance is < what ever you want it to be less than

Ehm... Why use Math.Distance to check collision on a box? It's just adding extra complications.
