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°täp yeah, compare it with the Error23 part.
With nice Plus/4 colours!
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.

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.
