I've been making a program that draws a line repeatedly with =
different colours through a loop that ends at the coordinates if a =
circle..=20
--------- >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> =
()
the line line travels and hits a =
ball cirlce explodes =
when line touches =
=
it
The problem is, there is a trail behind the line of multiple colours. =
How can I be rid of this?
-Thanks

Hi,
For this I would recommend first drawing the new line then drawing a
line with the background color that goes from the beginning of the new
line to x pixels behind it (x is the amount of pixels you moved the
line). This should erases the old line and not cause the flicker you'd
get if you cleared the entire screen.
