View.Update?

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

What is it you are trying to achieve?
I am trying to make an animation

What is the problem you are having?
when the figure reaches near the end of the screen the animation drags, the rest of the animation if fine though. The animation in the code i have posted is a circle moving, but when it is almost off the screen it just stops, in other programs iv made to test this, they dragged, it seems that the animation is not getting cleared from the screen properly or something but i don't know

Describe what you have tried to solve this problem
used View.UpdateArea also





View.Set ("graphics, offscreenonly")
var x : int := 50

loop
x := x+1
Time.Delay (10)
Draw.Fill (x, 50, 0, 0)
Draw.FillOval (x, 50, 50, 50, 16)
View.UpdateArea (0, 0, maxx, maxy)
end loop


Please specify what version of Turing you are using
Version 4.1

RE:View.Update?

So you should be re-drawing only those areas using View.UpdateArea(). You're already doing that, except you're using it to update the whole screen instead of just one small spot. Alternatively (and preferably), just re-draw everything instead of just the circle.

The Draw.Fill procedure is used to color in a figure that is on the screen.

Suppose we pass an (x, y) point to Draw.Fill that is NOT on the screen. What should happen then?
