I made this program but the animation is not smooth. Can somone tell me what i did wrong.
setscreen ("graphics:450;400")
var pointx, pointy,level,difficult,psize,bouncer,bouncex,bouncey : int := 0
var centy,centx:int:=20
var mover : string (1)
var col,score,endscore: int := 0
var font1:int
process paddle
Draw.FillBox (5, col, 10, col + 100, blue)
loop
if hasch then
getch (mover)
if mover = chr (200) then
col := col + 10
elsif mover = chr (208) then
col := col - 10
end if
end if
Draw.FillBox (5, col, 10, col + 100, blue)
View.Update


delay(20)
cls

end loop
end paddle

fork paddle

thanks

you set screen to graphics mode, you should have set it to offscreenonly instead

can anyone give me an example where input.keydown is less beneficial than hasch/getch structure?

it never is
getch/hasch will always be slower and less useful
the only case that might be presented is less lines
like it would be pointless to use keydown for this:
loop
exit when hasch
end loop

I need the getch/hasch because the program is supposed to be a paddle for the game pong. i have to make it for a school project. but if you have any suggestions on how to do it better please share them.
thanks

yeah. i prefer to use input.keydown too becuase it runs a hella lot faster. but it's only supported in turing 4.x not 3.x same with View.Set("offscreenonly")/View.Update

i think getch also has the unfortunate feature of needing a buffer when you press keys down too quickly

like when moving a circle, you can flood and make it move after you've stopped pressing on a key
