Part of Crackers Demo 4, but released as a separate file too.
In the tunnel part move the joystick, or press keys A W 3 4 SHIFT in order to drive the tunnel, space or "do nothing" to leave it. |

Best 8-bit tunnel ever? |
|
|

Oops, forgot my thumb. |

Aren't those exactly the same effects that I just saw in another recent resource demo? :) |

tömäes: Yes, they are the same (except the tunel has bigger resolution), but we didn't have time to polish those parts, they are just linked in.
Preacher: I hope it is the best. :) I'm very proud of that effect. |

Is it the only true freedirectional tunnel on the C16/C64? I think so.. how did you do that?! |

Optimus: There is a texture coordinate and shading table used and a rotation table. One "pixel" is computed like this:
ldx rot ;rotation around z
lda table_row,x
ldy table_col,y
sta t+1 ;write the high byte
lax (t),y ;read texture coordinate
lda texture,x ;read actual texture
iny ;switch to the shading table
adc (t),y ;add shading
sta screen ;done
The texture movement and one rotation is done by "texture" table shifts, and one rotation (offset) is in the lower byte of the "t" 16bit pointer. |

Marvelous! |

Nice music and gfx in the first part (screenshot). While I appreciate the code for the FD tunnel I can't really say I like it because of the low resolution. :/ So thumbs up for the code. :) |
|
|
YAY :)

Fine stuff.
Optional song for TED would be nice. |
