bluatigro,

where is the original _opengl_dbl file?? maybe you could just edit first post with what you have so far, just edit the code sniblets to reflect the changes you have made, and have ALL the programs needed to run...

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

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