animating objects without smearing

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

this question is probably easy to answer

how do you animate an object without it smearking away a multi colour background

if the background is solid, i draw the object, put a delay, and cover it up using a counting loop

but if it is different colours in the back when i cover it up, i can only cover up with one colour 

help

simplest way - just use an image for the background and redraw that

Smearing the image?? I think I understand...
Basically, what I'd say is make your colored background, and make a ball. You want the ball to be (for example) red. So...lets just say we want the ball to move to the right (x:=x+1  or   x+=1).  Ok, first, draw the background, (drawfillbox(0,0,maxx,maxy, -bg color- )), then draw the redball as its x,y co-ordinates (drawfilloval(x,y,5,5,red))...ok, now make it move (x+=1). I'd suggest putting in a delay, like mebe (delay(5)), then the loop will restart, drawing the background over the previous ball, and redrawing the new ball in its new position! That will make the ball move without leaving a colored "smear" across your background.

var x,y:int:=5
y:=200
loop
drawfillbox(0,0,maxx,maxy,black)
drawfilloval(x,y,5,5,red)
x+=1
delay(5)
exit when x>maxx
end loop

lol   this is simple  there is to ways to do it  either  make a delay n tell it to redraw the same image in the same spot  the same color as the back ground n then draw the image in the next spot         example
    drawline (12,12,45,45,4) 
 delay (1000)
 drawline (12,12,45,45,0)
 drawline (24,24,57,57,4) 
or draw the image n background then delay  and then clear the screen and re draw the line in a different location 

drawline (10,10,100,100,4)
delay (1000)
cls 
drawline (30,30,130,130,4)

the secound way generates more code if the is alot lot on the screen  can be choppy depends on how u go about doing it
