If I set the camera.z to 10
Then create the colour parameter for the text:
I did:
dim as sng4d g=type(100,10,0,1)
just before the loop.
Then
text "GAME OVER",g

It looks really good.
Thank you.

what is wrong whit the folowing code ?

if i use this i get a black screen

it shoot draw a '?' on screen

Code: Select all

sub vraag( lim as integer , i as integer )
  if i < 0 then
    sphere 0 , 0 , 0 , .1 , green
  else
    glpushmatrix
      child 0 , .1 , 0 , lim , xyz
      vraag lim , i - 1
    glpopmatrix
  end if
end sub
sub vraagteken( hoek as double )
  glpushmatrix 
    skelet 0 , 0 , 0 , hoek
    skelet 1 , 0 , 0 , -hoek
    vraag 0 , 5
    vraag 1 , 25
  glpopmatrix

My guess would be no Flip? You are not flipping the working buffer onto the screen buffer.
