06:56:36 <_zephyris> Hmm, OpenGFX2 rock homework then.
07:07:54 <peter1138> Could be worse, could be zBase.
07:08:08 <peter1138> 159 sprites missing.
07:15:33 <peter1138> What if rough tiles generated in clusters like rocks?
07:21:31 <peter1138> Forgot to mention in the coastal rocks change there's actually a random seed collision bugfix, previously on maps larger than 256x256, the tile index bits overlapped with the number of rocks bits, so the number of rocks would depend on where they started.
07:24:57 *** SigHunter has quit IRC (Remote host closed the connection)

07:44:50 <utrain> _jgr_: Out if curiosity, what's up with the API that sucks?
07:50:22 <_jgr_> utrain: It turns "iterate all the tiles in this area" into "fill in an expensive/inefficient data structure with every tile index in this area", which has very different performance characteristics
07:50:37 <_jgr_> In general it encourages inefficient code which performs badly
08:02:13 <peter1138> A couple of simple for-loops in squirrel would be better.
08:36:23 *** MinchinWeb[m] has quit IRC (Ping timeout: 480 seconds)

09:11:15 *** MinchinWeb[m] has joined #openttd
10:24:01 <peter1138> I guess we could come up with an actual iterator-based system that is independent from ScriptList.
10:26:12 *** MinchinWeb[m] has quit IRC (Ping timeout: 480 seconds)
10:26:45 <LordAro> what would that look like?
10:27:06 *** MinchinWeb[m] has joined #openttd
10:38:15 <peter1138> Something like `area = TileArea(start, end); for (tile = area->Begin(); !area->End(); it = area->Next()) { ... }`
10:39:02 <peter1138> Different objects for things like indsutry layouts.
10:40:03 <peter1138> Then you could have a modifiable one with things like AddRectangle() that uses a std::vector<TileIndex> to store tiles, which is inefficient but not as inefficient as a ScriptList.
10:40:19 *** WormnestAndroid has quit IRC (Read error: Connection reset by peer)
10:40:21 <peter1138> And then clearly define rules that if you modify it while iterating you screwed up.
10:40:32 <peter1138> (current iterators allow stupid things)

10:50:23 <peter1138> A BitmapTileArea is even more memory efficient, but harder to resize.
10:51:58 <peter1138> std::vector<bool> is always fun :p

19:15:25 <kuhnovic> talltyler: I like it, looks much more organic compared to everything being covered in rocks

19:20:38 <talltyler> It'll be good for your rocky Southern Norway map 😄
