program flashes

[jrblast]

Well, in light of finishing my game of snake, i decided to move onto a more complex game...much of the coded so far i took from the astroids game lol, anyways, it keeps flashing, i use the viewupdate thing, but it still flashes, any ideas? heres the code btw

code:

const ballRad : int := 10           %declaring constants and vars const paddleWidth : int := 30 const paddleThicnkness : int := 10 const paddleHeight : int := 5 const screenX : int := 900 const screenY : int := 700 const frameDelay : int := 5 const rate : int := 5 var mouseX, mouseY, ballX, ballY, button, ballDX, ballDY, ballAngle, collision, paddleX : int ballX := 450                 %giving values to variables ballY := 350 ballDX := 0 ballDY := -1 mouseX := screenX div 2 paddleX := 350 setscreen ("offscreenonly, nobuttonbar, graphics:900;,700") loop     cls     mousewhere (mouseX, mouseY, button)     ballX += ballDX     ballY += ballDY     if mouseX > paddleX then         paddleX += rate     end if     if mouseX < 0 or mouseX > maxx then         mouseX := 0     end if     if mouseX - paddleWidth >= 0 and mouseX + paddleWidth <= screenX then         drawfilloval (ballX, ballY, ballRad, ballRad, brightred)         drawfillbox (mouseX - paddleWidth, paddleHeight, mouseX + paddleWidth, paddleHeight + paddleThicnkness, black)     else         end if     delay (frameDelay)     View.Update end loop

any helps appreciated

View.Update works with "offscreenonly"

You have a mess of a declaration there

code:

setscreen ("offscreenonly, nobuttonbar, graphics:900;,700")

I'd think that graphics might overwrite offscreenonly.

:O your right tyvm

[do_pete]

you have to get rid of the "," after "graphics: 900;"

It doesn't, any of it can be in any order.

Your delay needs to be AFTER the View.Update.

that's why I've said "might", I didn't have Turing at the moment of writing to try it out.

codemage has gotten it though. Delay after View.Update

Just correcting you for anyone else's benefit. You can't check, so why don't I?

About the delay after View.Update, although that would be better coding, it's not necessary to eliminate the flickering.
