Sometimes LBB's graphics output is slower than LB's, and this Wiki article explains how that can often be resolved. A program posted by John Fisher at the Just BASIC forum illustrates this very well. The version published there runs noticeably more slowly in LBB than in LB, but if you modify it as below - i.e. create one long GUI command string - it runs more quickly in LBB:
Code: nomainwin
UpperLeftX = 20
UpperLeftY = 20
WindowWidth = 550
WindowHeight = 570
dim grid( 25, 25)
for x =0 to 24
for y =0 to 24
grid( x, y) =int( 2 *rnd( 1))
next y
next x
open "Show 2D array" for graphics_nsb as #wg
#wg "trapclose [quit]"
#wg "color white"
gui$ = "down ; fill 60 60 60"
for x =0 to 24
for y =0 to 24
gui$ += ";backcolor "
if grid( x, y)=0 then gui$ += "black" else gui$ += "white"
gui$ += ";place "; 20 +20 *x; " "; 20 +20 *y
gui$ += "; boxfilled "; 20 +20 *x +16; " "; 20 +20 *y +16
next y
next x
#wg gui$
wait
[quit]
close #wg
end
Of course this version is LBB-specific by virtue of the += operators. If you want to make it LB compatible you will need to substitute gui$ = gui$ +
Richard.
