    TBGL Stars with twinkle

    Here is very basic example on star flight.
    It is hardly revolutionary, but can show you how entity system can be used for this common task.

    Interesting to watch how much the twinkle improved the feeling of depth and masked reincarnating stars in the background.

    Hi Petr,

    Looks wonderfully serene. I am sure there are nebulae, galaxies and planetary systems forming in the background - perhaps they are made of dark matter.

    It reminds me of something you'd probably see in Star Trek.

    This colors the stars using pseudo random numbers derived from the star iterator e.
    [code=thinbasic]
    ' -- Color change to simulate twinkle
    c = sin(gettickcount*0.01+e)*.25+1.75
    '
    'pseudorandom tints
    fr=(e*123) and msk
    fg=(e*571) and msk
    fb=(e*579) and msk
    '
    TBGL_EntitySetColor(%sScene, e, fr*c, fg*c, fb*c)
    [/code]

    A few purple stars hurtling past could be attributed to the Doppler effect when travelling near the speed of light. - unlike our red-shifted view from planet Earth.

    Re: TBGL Stars with twinkle

    That is nice interpretation

    At one point I was thinking whether to restrict maximum speed of tbgl entities to 299 792 458 m/s, then I realised I should take a rest

    When coding, my head spins so fast, time slows down relative to everybody elses.
