  21 =============================== NOTES ==============================\r
  22 NOTE: Things starting with TODO are sometimes only suggestions.\r
  23 \r
  24 NOTE: VBO cannot be turned on for fast-changing stuff because there\r
  25       is an apparanet memory leak in irrlicht when using it (not sure)\r
  26           - It is not a memory leak but some kind of a buffer.\r
  27 \r
  28 NOTE: iostream.imbue(std::locale("C")) is very slow\r
  29 NOTE: Global locale is now set at initialization\r
  30 \r
  31 SUGG: Fix address to be ipv6 compatible\r
  32 \r
  33 NOTE: When a new sector is generated, it may change the ground level\r
  34       of it's and it's neighbors border that two blocks that are\r
  35           above and below each other and that are generated before and\r
  36           after the sector heightmap generation (order doesn't matter),\r
  37           can have a small gap between each other at the border.\r
  38 SUGG: Use same technique for sector heightmaps as what we're\r
  39       using for UnlimitedHeightmap? (getting all neighbors\r
  40           when generating)\r
  41 \r
  42 SUGG: Transfer more blocks in a single packet\r
  43 SUGG: A blockdata combiner class, to which blocks are added and at\r
  44       destruction it sends all the stuff in as few packets as possible.\r
  45 \r
  46 SUGG: If player is on ground, mainly fetch ground-level blocks\r
  47 SUGG: Fetch stuff mainly from the viewing direction\r
  48 \r
  49 SUGG: Expose Connection's seqnums and ACKs to server and client.\r
  50       - This enables saving many packets and making a faster connection\r
  51           - This also enables server to check if client has received the\r
  52             most recent block sent, for example.\r
  53 SUGG: Add a sane bandwidth throttling system to Connection\r
  54 \r
  55 SUGG: More fine-grained control of client's dumping of blocks from\r
  56       memory\r
  57           - ...What does this mean in the first place?\r
  58 \r
  59 SUGG: A map editing mode (similar to dedicated server mode)\r
  60 \r
  61 SUGG: Add a time value to the param of footstepped grass and check it\r
  62       against a global timer when a block is accessed, to make old\r
  63           steps fade away.\r
  64 \r
  65 SUGG: Make a copy of close-range environment on client for showing\r
  66       on screen, with minimal mutexes to slow down the main loop\r
  67 \r
  68 SUGG: Make a PACKET_COMBINED which contains many subpackets. Utilize\r
  69       it by sending more stuff in a single packet.\r
  70           - Add a packet queue to RemoteClient, from which packets will be\r
  71             combined with object data packets\r
  72                 - This is not exactly trivial: the object data packets are\r
  73                   sometimes very big by themselves\r
  74 \r
  75 SUGG: Split MapBlockObject serialization to to-client and to-disk\r
  76       - This will allow saving ages of rats on disk but not sending\r
  77             them to clients\r
  78 \r
  79 SUGG: MovingObject::move and Player::move are basically the same.\r
  80       combine them.\r
  81 \r
  82 SUGG: Precalculate lighting translation table at runtime (at startup)\r
  83       - This is not doable because it is currently hand-made and not\r
  84             based on some mathematical function. Now it is not.\r
  85 \r
  86 SUGG: A version number to blocks, which increments when the block is\r
  87       modified (node add/remove, water update, lighting update)\r
  88           - This can then be used to make sure the most recent version of\r
  89             a block has been sent to client\r
  90 \r
  91 SUGG: Make the amount of blocks sending to client and the total\r
  92           amount of blocks dynamically limited. Transferring blocks is the\r
  93           main network eater of this system, so it is the one that has\r
  94           to be throttled so that RTTs stay low.\r
  95 \r
  96 SUGG: Meshes of blocks could be split into 6 meshes facing into\r
  97       different directions and then only those drawn that need to be\r
  98           - Also an 1-dimensional tile map would be nice probably\r

 101       bartwe's game\r
 102 \r
 103 Gaming ideas:\r
 104 -------------\r
 105 \r
 106 - Aim for something like controlling a single dwarf in Dwarf Fortress\r
 107 \r
 108 - The player could go faster by a crafting a boat, or riding an animal\r
 109 \r
 110 - Random NPC traders. what else?\r

 139       - create copies of all textures for all lighting values and only\r
 140             change texture for material?\r
 141           - Umm... the collecting of the faces is the slow part\r
 142             -> what about just changing the color values of the existing\r
 143                    meshbuffers? It should go quite fast.\r
 144                    - This is not easy; There'd need to be a buffer somewhere\r
 145                      that would contain the night and day lighting values.\r

 152           - This is not easy; all the MapBlocks close to the player would\r
 153             still need to be drawn separately and combining the blocks\r

 266 --------------------------------------\r
 267 # maybe done\r
 268 * not done\r
 269 \r
 270 === Stuff to do before release\r
 271 * Save the new mapgen stuff\r
 272   - map/meta.txt, which should contain only plain text, something like this:\r
 273       seed = 7ff1bafcd7118800\r
 274       chunksize = 8\r
 275   - map/chunks.dat: chunk positions and flags in binary format\r
 276 * Make server find the spawning place from the real map data, not from\r
 277   the heightmap\r
 278   - But the changing borders of chunk have to be avoided, because\r
 279     there is time to generate only one chunk.\r
 280 * Make the generator to run in background and not blocking block\r
 281   placement and transfer\r
 282 * only_from_disk might not work anymore - check and fix it.\r
 283 * Check the fixmes in the list above\r
 284 \r
 285 === Making it more portable\r
 286 * MinGW: Switch away from swprintf; mingw has a bad version of it.\r
 287   Use snprintf + narrow_to_wide or (w)ostringstream\r
 288 * Some MSVC: std::sto* are defined without a namespace and collide\r
 289   with the ones in utility.h\r
 290 \r
 291 === Stuff to do after release\r
 292 * Make an "environment metafile" to store at least time of day\r
 293 * Move digging property stuff from material.{h,cpp} to mapnode.cpp...\r
 294   - Or maybe move content_features to material.{h,cpp}?\r
 295 * Add some kind of erosion and other stuff that now is possible\r
 296 * Make client to fetch stuff asynchronously\r
 297   - Needs method SyncProcessData\r
 298 * Fix the problem with the server constantly saving one or a few\r
 299   blocks? List the first saved block, maybe it explains.\r
 300   - It is probably caused by oscillating water\r
 301 * Water doesn't start flowing after map generation like it should\r
 302   - Are there still problems?\r
 303 * Better water generation (spread it to underwater caverns but don't\r
 304   fill dungeons that don't touch big water masses)\r
 305 * When generating a chunk and the neighboring chunk doesn't have mud\r
 306   and stuff yet and the ground is fairly flat, the mud will flow to\r
 307   the other chunk making nasty straight walls when the other chunk\r
 308   is generated. Fix it.\r
 309 * Make a small history check to transformLiquids to detect and log\r
 310   continuous oscillations, in such detail that they can be fixed.\r
 311 * Combine meshes to bigger ones in ClientMap and set them EHM_STATIC\r
