I need to find a way to make a box appear in random places, (but you cannot move thru the box)

not i know it has to do with randint and the parimeters being variables, but the box comes out distorted every time!

Can someone please help me out?

You're going to want to store a random location using two Rand.Ints: one for the x position of the box, one for the y. You'll also want to know the width and the height of the box. Draw the box using all that information. Then, collision detection.

ok so i have this

code:
proc fini
var x: int
var y :int
randint (x, 200, 300)
randint  (y, 100, 200)
    drawfillbox (y, x, x, y, grey)
    drawfillbox (maxx - 30, 60, maxx - 60, 30, 0)
end fini



but it just keeps moving and the box wont stay in one position, plus im not sure how to make it move as a whole to other places.
Can anyone help??

It's probably not staying in one spot because you've probably got that procedure inside a loop.
To actually move the box, do what I said before.

Why you are drawing the box at (y,x) (x, y) is beyond me.

So basically you want a shape of the same size to appear in random locations on the screen?

for i:1..100 %how many boxes you want
    randint(x,0,maxx-30)
    randint(y,0,maxy-30)
    randint(clr,0,maxcolor)

If you want to stop making the boxes jump around the screeneliminate the loop... Rolling Eyes

yes buit when i take them out of the loop, they dissapear very fast

then your probably clear the screen. i guess you want a random box that wont be cleared right?
code:
%put out of loop
var x:int:=Rand.Int(0,maxx-30)
var y:int:=Rand.Int(0,maxy-30)
var clr:int:=Rand.Int(0,maxcolor)
%in loop
drawfillbox(x,y,x+30,y+30,clr)
