here is an example screen for hiding all 3d until you are ready to show it.
Did you mean something in regards with hiding the 2d image while using the get image command prior to your game starting?
sync on : sync rate 60
ink rgb(255,255,255),1
randomize timer()
backdrop off
for i = 1 to 100
make object cube i,1
color object i,rgb(rnd(255),rnd(255),rnd(255))
rotate object i,rnd(360),rnd(360),rnd(360)
rem this is a dbp line only
box 0,0,screen width(),screen height(),rgb(55,55,255),rgb(55,55,255),rgb(55,55,55),rgb(55,55,55)
rem use these if using classic
`ink rgb(255,55,55),1
`box 0,0,screen width(),screen height()
ink rgb(255,255,255),1
center text screen width()/2,screen height()/2,"Loading Cube :"+STR$(i)
sync
rem this wait is just to slow it down to show the visual effect
rem can be removed
wait 100
next i
cls
backdrop on
disable escapekey
while escapekey()=0
center text screen width()/2,screen height()/2,"All cubes loaded"
sync
endwhile
for i = 1 to 100
delete object i
next i
end
