need some help here >.<

for this assignment i got, i made my background in turing and i made my thing to move around with loop, my problem is how to move my thing with clear screen without reprinting my background? it look weird when it prints background everytime, kinda flashy.

look into View.Update

[A.J]

to avoid the 'flashiness', try looking up View.Update in the Turing Walkthrough

EDIT : Sorry Tony...looks like you posted right before I did...

You can't draw multiple layers. What you want to do is draw the entire screen before displaying it. Check out View.Set and View.Update.

EDIT: Holy hell, beaten twice.

There's no way to do this. What you want to do is use "offscreenonly", draw to the backbuffer, and call View.Update when you're done drawing everything for the current frame. Example:

Turing:

setscreen ("offscreenonly") const baseshift := 150 var shift := baseshift proc DrawBackground     drawfillbox (0, 0, maxx, maxy, blue) end DrawBackground proc DrawObject (xshift, yshift : int)     var x := (maxx div 2) + xshift     var y := (maxy div 2) + yshift     var r := 50     drawfilloval (x, y, r, r, red) end DrawObject var speed := 1 var deg := 0 var speed2 := 5 var deg2 := 0 var xs, ys : int loop     deg2 += speed2     shift := round(cosd(deg2) * baseshift)     deg += speed     xs := round (cosd (deg) * shift)     ys := round (sind (deg) * shift)     DrawBackground     DrawObject(xs, ys)     View.Update ()     Time.DelaySinceLast(20) end loop

Look 'mah, no flickering!
