Chopy Lines

[Lucas]

What is it you are trying to achieve?
When i say to draw the line, Im just drawing from one point to the next point, then so on, but the values of the points seem to change, or at least thats what i think, since noone of the points actually touch, and its all choppy. so im just wondering why this is happening and is there a way to make it smooth?

Turing:

View.Set ("graphics: 800; 800, offscreenonly") type data :     record         x, y, dix, diy : real         count, num : int     end record var points : array 1 .. 720 of data var t : real := 0 var numpoints : int := 180 for a : 1 .. numpoints     points (a).x := maxx div 2     points (a).y := maxy div 2     points (a).dix := 0     points (a).diy := 0     points (a).count := a     points (a).num := a end for colorback (black) loop     t += 2     for a : 1 .. numpoints         points (a).count -= 1         if points (a).count < 0 then             points (a).x := maxx div 2             points (a).y := maxy div 2             points (a).dix := sind (t) * 4             points (a).diy := cosd (t) * 4             points (a).count := numpoints         end if         points (a).x += points (a).dix         points (a).y += points (a).diy         if points (a).x > maxx or points (a).x < 0 then             points (a).dix := -points (a).dix         end if         if points (a).y > maxy or points (a).y < 0 then             points (a).diy := -points (a).diy         end if         if points (a).num not= numpoints then             Draw.Line (points (points (a).num).x div 1, points (points (a).num).y div 1, points (points (a + 1).num).x div 1, points (points (a + 1).num).y div 1, white)         end if         Draw.Line (points (points (numpoints).num).x div 1, points (points (numpoints).num).y div 1, points (points (1).num).x div 1, points (points (1).num).y div 1, white)     end for     View.Update     delay (5)     cls end loop

Please specify what version of Turing you are using
4.1.1

Perhaps because you're calculating movement and rendering at the same time.

You're rendering a line to the next point before it's moved for that frame. Get in the habit of breaking up logic and drawing processes.

loop
resetSelectedPoints
movePoints
renderLines
end loop

aaahhhh okay thx
