Description Jeffrey Pfau 2013-10-10 18:50:49 PDT

Mosaic is a graphical feature for pixelating various things on the screen. It will need to be implemented for both backgrounds and OBJs.

Comment 1 Jeffrey Pfau 2013-10-23 11:40:44 PDT

Initial mosaic implementation in 4b9e9f84bed415416e9669d89286711629e4f4b4, but this only works on mode 0 backgrounds, and only on tiles that aren't partially off-screen.

Buggy implementation on non-transformed OBJs landed in 775f9db546e1123bfb213f21ee687868397abeeb. It causes really weird effects in the Aria of Sorrow intro, which I haven't tracked down yet.

Comment 3 Jeffrey Pfau 2013-10-27 22:00:17 PDT

Bugs fixed in 8902635e3ab8a239541612b552e1ecd26c811350, now only transformed OBJs and modes 2 - 5 are unimplemented.

Comment 4 Jeffrey Pfau 2013-11-10 23:10:26 PST

Implemented mosaic for 256-color mode 0 in f8d58422408246f22e1c980bbf74c162ee1337f8

Comment 5 Jeffrey Pfau 2014-11-15 01:34:09 PST

Implemented for modes 2 - 5 in 81b85d1843a2e32aab25fd79e9da236e27619436, although I don't know how well it interacts with windows.

Comment 6 Jeffrey Pfau 2014-12-31 20:00:35 PST

16-color mode 0 mosaic + windows are fixed in bbfd7d8e2c3f46783edc8365f41c241194338b31, but 256-color is still broken, and modes 2 - 5 are unknowns.
