Room generation back in place


SpiceWare

1,036 views

The wall generation routines are back in place, as are the room shift routines. This is so the Playfield updates could be checked (it's really obvious when the room shifts left/right if one of the PFx updates is occuring at the wrong time).

 

Use the Left Difficulty switch to select Berzerk or Frenzy layout.

 

Use right joystick to change rooms.

 

Use left joystick to position robots.

 

To check the PFx updates for all 22 reposition kernels I tested with X positions of 00, 0F, 1E, 2D, 3C, 4B, 5A, 69, 78, 87 and 96.

 

Edit: Forgot to mention that the logic for Select and Restart is also in place. There's a dummy menu of just colored scanlines at the moment.

Looks good.

 

When scrolling vertically the final row does not scroll off the screen and forms the start of the new room. However, when scrolling horizontally the walls scroll off the sides completely, which leads to a bit of a nasty jump when the new room is drawn. Would it be possible to scroll horizontally in the same way? I think you would need to scroll by 2 columns less than before and clear the outer two columns at each step. Let me know if this makes any sense as it is hard to describe!
