  21 =============================== NOTES ==============================\r
  22 NOTE: Things starting with TODO are sometimes only suggestions.\r
  23 \r
  24 NOTE: iostream.imbue(std::locale("C")) is very slow\r
  25 NOTE: Global locale is now set at initialization\r
  26 \r
  27 NOTE: If VBO (EHM_STATIC) is used, remember to explicitly free the\r
  28       hardware buffer (it is not freed automatically)\r
  29 \r
  30 Old, wild and random suggestions that probably won't be done:\r
  31 -------------------------------------------------------------\r
  32 \r
  33 SUGG: If player is on ground, mainly fetch ground-level blocks\r
  34 \r
  35 SUGG: Expose Connection's seqnums and ACKs to server and client.\r
  36       - This enables saving many packets and making a faster connection\r
  37           - This also enables server to check if client has received the\r
  38             most recent block sent, for example.\r
  39 SUGG: Add a sane bandwidth throttling system to Connection\r
  40 \r
  41 SUGG: More fine-grained control of client's dumping of blocks from\r
  42       memory\r
  43           - ...What does this mean in the first place?\r
  44 \r
  45 SUGG: A map editing mode (similar to dedicated server mode)\r
  46 \r
  47 SUGG: Transfer more blocks in a single packet\r
  48 SUGG: A blockdata combiner class, to which blocks are added and at\r
  49       destruction it sends all the stuff in as few packets as possible.\r
  50 SUGG: Make a PACKET_COMBINED which contains many subpackets. Utilize\r
  51       it by sending more stuff in a single packet.\r
  52           - Add a packet queue to RemoteClient, from which packets will be\r
  53             combined with object data packets\r
  54                 - This is not exactly trivial: the object data packets are\r
  55                   sometimes very big by themselves\r
  56           - This might not give much network performance gain though.\r
  57 \r
  58 SUGG: Precalculate lighting translation table at runtime (at startup)\r
  59       - This is not doable because it is currently hand-made and not\r
  60             based on some mathematical function.\r
  61                 - Note: This has been changing lately\r
  62 \r
  63 SUGG: A version number to blocks, which increments when the block is\r
  64       modified (node add/remove, water update, lighting update)\r
  65           - This can then be used to make sure the most recent version of\r
  66             a block has been sent to client, for example\r
  67 \r
  68 SUGG: Make the amount of blocks sending to client and the total\r
  69           amount of blocks dynamically limited. Transferring blocks is the\r
  70           main network eater of this system, so it is the one that has\r
  71           to be throttled so that RTTs stay low.\r
  72 \r
  73 SUGG: Meshes of blocks could be split into 6 meshes facing into\r
  74       different directions and then only those drawn that need to be\r
  75 \r
  76 SUGG: Calculate lighting per vertex to get a lighting effect like in\r
  77       bartwe's game\r
  78 \r
  79 SUGG: Background music based on cellular automata?\r
  80       http://www.earslap.com/projectslab/otomata\r
  81 \r
  82 SUGG: Simple light color information to air\r
  83 \r
  84 SUGG: Server-side objects could be moved based on nodes to enable very\r
  85       lightweight operation and simple AI\r
  86         - Not practical; client would still need to show smooth movement.\r
  87 \r
  88 SUGG: Make a system for pregenerating quick information for mapblocks, so\r
  89           that the client can show them as cubes before they are actually sent\r
  90           or even generated.\r
  91 \r
  92 Gaming ideas:\r
  93 -------------\r
  94 \r
  95 - Aim for something like controlling a single dwarf in Dwarf Fortress\r
  96 - The player could go faster by a crafting a boat, or riding an animal\r
  97 - Random NPC traders. what else?\r
  98 \r
  99 Game content:\r
 100 -------------\r
 101 \r
 102 - When furnace is destroyed, move items to player's inventory\r
 103 - Add lots of stuff\r
 104 - Glass blocks\r
 105 - Growing grass, decaying leaves\r
 106         - This can be done in the active blocks I guess.\r
 107         - Lots of stuff can be done in the active blocks.\r
 108         - Uh, is there an active block list somewhere? I think not. Add it.\r
 109 - Breaking weak structures\r
 110         - This can probably be accomplished in the same way as grass\r
 111 - Player health points\r
 112         - When player dies, throw items on map (needs better item-on-map\r
 113           implementation)\r
 114 - Cobble to get mossy if near water\r
 115 - More slots in furnace source list, so that multiple ingredients\r
 116   are possible.\r
 117 - Keys to chests?\r
 118 \r
 119 - The Treasure Guard; a big monster with a hammer\r
 120         - The hammer does great damage, shakes the ground and removes a block\r
 121         - You can drop on top of it, and have some time to attack there\r
 122           before he shakes you off\r
 123 \r
 124 - Maybe the difficulty could come from monsters getting tougher in\r
 125   far-away places, and the player starting to need something from\r
 126   there when time goes by.\r
 127   - The player would have some of that stuff at the beginning, and\r
 128     would need new supplies of it when it runs out\r
 129 \r
 130 - A bomb\r
 131 - A spread-items-on-map routine for the bomb, and for dying players\r
 132 \r
 133 - Fighting:\r
 134   - Proper sword swing simulation\r
 135   - Player should get damage from colliding to a wall at high speed\r

 151 Graphics:\r
 152 ---------\r
 153 \r
 154 SUGG: Combine MapBlock's face caches to so big pieces that VBO\r
 155       can be used\r
 156       - That is >500 vertices\r
 157           - This is not easy; all the MapBlocks close to the player would\r
 158             still need to be drawn separately and combining the blocks\r
 159                 would have to happen in a background thread\r
 160 \r
 161 SUGG: Make fetching sector's blocks more efficient when rendering\r
 162       sectors that have very large amounts of blocks (on client)\r
 163           - Is this necessary at all?\r
 164 \r
 165 TODO: Flowing water animation\r
 166 \r
 167 SUGG: Draw cubes in inventory directly with 3D drawing commands, so that\r
 168       animating them is easier.\r
 169 \r
 170 SUGG: Option for enabling proper alpha channel for textures\r

 180 Client:\r
 181 -------\r
 182 \r
 183 TODO: Untie client network operations from framerate\r
 184       - Needs some input queues or something\r
 185           - This won't give much performance boost because calculating block\r
 186             meshes takes so long\r
 187 \r
 188 SUGG: Make morning and evening transition more smooth and maybe shorter\r
 189 \r
 190 TODO: Don't update all meshes always on single node changes, but\r
 191       check which ones should be updated\r
 192           - implement Map::updateNodeMeshes() and the usage of it\r
 193           - It will give almost always a 4x boost in mesh update performance.\r

 201 Server:\r
 202 -------\r
 203 \r
 204 SUGG: Make an option to the server to disable building and digging near\r
 205       the starting position\r
 206 \r
 207 FIXME: Server sometimes goes into some infinite PeerNotFoundException loop\r
 208 \r
 209 * Fix the problem with the server constantly saving one or a few\r
 210   blocks? List the first saved block, maybe it explains.\r
 211   - It is probably caused by oscillating water\r
 212 * Make a small history check to transformLiquids to detect and log\r
 213   continuous oscillations, in such detail that they can be fixed.\r

 221 ------------\r
 222 \r
 223 TODO: A list of "active blocks" in which stuff happens.\r
 224         + Add a never-resetted game timer to the server\r
 225         + Add a timestamp value to blocks\r

 232                 - Transform cobble to mossy cobble near water\r
 233                 - Run a custom script\r

 236         + When a block goes inactive:\r
 237                 + Store objects statically to block\r
 238                 + Store timer value as the timestamp\r

 245         + Initially it is fine to send information about every active object\r
 246           to every player. Eventually it should be modified to only send info\r
 247           about the nearest ones.\r
 248                 + This was left to be done by the old system and it sends only the\r
 249                   nearest ones.\r

 251 Objects:\r
 252 --------\r
 253 \r
 254 TODO: Get rid of MapBlockObjects and use only ActiveObjects\r
 255         - Skipping the MapBlockObject data is nasty - there is no "total\r
 256           length" stored; have to make a SkipMBOs function which contains\r
 257           enough of the current code to skip them properly.\r
 258 \r
 259 SUGG: MovingObject::move and Player::move are basically the same.\r
 260       combine them.\r

 271 TODO: Mineral and ground material properties\r

 273             some formula, as well as tool strengths\r
 274 \r
 275 TODO: Flowing water to actually contain flow direction information\r
 276       - There is a space for this - it just has to be implemented.\r
 277 \r
 278 SUGG: Erosion simulation at map generation time\r
 279         - Simulate water flows, which would carve out dirt fast and\r
 280           then turn stone into gravel and sand and relocate it.\r
 281         - How about relocating minerals, too? Coal and gold in\r
 282           downstream sand and gravel would be kind of cool\r
 283           - This would need a better way of handling minerals, mainly\r
 284                 to have mineral content as a separate field. the first\r
 285                 parameter field is free for this.\r

 287           enough solid rock from the bottom\r

 289 SUGG: Try out the notch way of generating maps, that is, make bunches\r
 290       of low-res 3d noise and interpolate linearly.\r
 291 \r
 292 Mapgen v2:\r
 293 * Possibly add some kind of erosion and other stuff\r
 294 * Better water generation (spread it to underwater caverns but don't\r
 295   fill dungeons that don't touch big water masses)\r
 296 * When generating a chunk and the neighboring chunk doesn't have mud\r
 297   and stuff yet and the ground is fairly flat, the mud will flow to\r
 298   the other chunk making nasty straight walls when the other chunk\r
 299   is generated. Fix it. Maybe just a special case if the ground is\r
 300   flat?\r
 301 \r
 302 Misc. stuff:\r
 303 ------------\r
 304 * Move digging property stuff from material.{h,cpp} to mapnode.cpp\r
 305   - ...Or maybe move content_features to material.{h,cpp}?\r
 306 \r
 307 Making it more portable:\r
 308 ------------------------\r
 309  \r
 310 Stuff to do before release:\r
 311 ---------------------------\r
 312 \r
 313 Fixes to the current release:\r
 314 -----------------------------\r
 315 \r
 316 Stuff to do after release:\r
 317 ---------------------------\r
 318 - Make sure server handles removing grass when a block is placed (etc)\r
 319     - The client should not do it by itself\r
 320 - Block cube placement around player's head\r
 321 - Protocol version field\r
 322 - Consider getting some textures from cisoun's texture pack\r
 323         - Ask from Cisoun\r
 324 - Make sure the fence implementation and data format is good\r
 325         - Think about using same bits for material for fences and doors, for\r
 326         example\r
 327 - Finish the ActiveBlockModifier stuff and use it for something\r
 328 - Move mineral to param2, increment map serialization version, add conversion\r
