  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 SUGG: Erosion simulation at map generation time\r
  93         - Simulate water flows, which would carve out dirt fast and\r
  94           then turn stone into gravel and sand and relocate it.\r
  95         - How about relocating minerals, too? Coal and gold in\r
  96           downstream sand and gravel would be kind of cool\r
  97           - This would need a better way of handling minerals, mainly\r
  98                 to have mineral content as a separate field. the first\r
  99                 parameter field is free for this.\r
 100         - Simulate rock falling from cliffs when water has removed\r
 101           enough solid rock from the bottom\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 - The player could go faster by a crafting a boat, or riding an animal\r
 108 - Random NPC traders. what else?\r
 109 \r
 110 Game content:\r
 111 -------------\r
 112 \r
 113 - When furnace is destroyed, move items to player's inventory\r
 114 - Add lots of stuff\r
 115 - Glass blocks\r
 116 - Growing grass, decaying leaves\r
 117         - This can be done in the active blocks I guess.\r
 118         - Lots of stuff can be done in the active blocks.\r
 119         - Uh, is there an active block list somewhere? I think not. Add it.\r
 120 - Breaking weak structures\r
 121         - This can probably be accomplished in the same way as grass\r
 122 - Player health points\r
 123         - When player dies, throw items on map (needs better item-on-map\r
 124           implementation)\r
 125 - Cobble to get mossy if near water\r
 126 - More slots in furnace source list, so that multiple ingredients\r
 127   are possible.\r
 128 - Keys to chests?\r
 129 \r
 130 - The Treasure Guard; a big monster with a hammer\r
 131         - The hammer does great damage, shakes the ground and removes a block\r
 132         - You can drop on top of it, and have some time to attack there\r
 133           before he shakes you off\r
 134 \r
 135 - Maybe the difficulty could come from monsters getting tougher in\r
 136   far-away places, and the player starting to need something from\r
 137   there when time goes by.\r
 138   - The player would have some of that stuff at the beginning, and\r
 139     would need new supplies of it when it runs out\r
 140 \r
 141 - A bomb\r
 142 - A spread-items-on-map routine for the bomb, and for dying players\r
 143 \r
 144 - Fighting:\r
 145   - Proper sword swing simulation\r
 146   - Player should get damage from colliding to a wall at high speed\r

 165 SUGG: Combine MapBlock's face caches to so big pieces that VBO\r
 166       can be used\r
 167       - That is >500 vertices\r
 168           - This is not easy; all the MapBlocks close to the player would\r
 169             still need to be drawn separately and combining the blocks\r
 170                 would have to happen in a background thread\r
 171 \r
 172 SUGG: Make fetching sector's blocks more efficient when rendering\r
 173       sectors that have very large amounts of blocks (on client)\r

 203       - Needs some input queues or something\r

 211           - implement Map::updateNodeMeshes() and the usage of it\r
