  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 NOTE: A random to-do list saved here as documentation:\r
  31 A list of "active blocks" in which stuff happens. (+=done)\r
  32         + Add a never-resetted game timer to the server\r
  33         + Add a timestamp value to blocks\r
  34         + The simple rule: All blocks near some player are "active"\r
  35         - Do stuff in real time in active blocks\r
  36                 + Handle objects\r
  37                 - Grow grass, delete leaves without a tree\r
  38                 - Spawn some mobs based on some rules\r
  39                 - Transform cobble to mossy cobble near water\r
  40                 - Run a custom script\r
  41                 - ...And all kinds of other dynamic stuff\r
  42         + Keep track of when a block becomes active and becomes inactive\r
  43         + When a block goes inactive:\r
  44                 + Store objects statically to block\r
  45                 + Store timer value as the timestamp\r
  46         + When a block goes active:\r
  47                 + Create active objects out of static objects\r
  48                 - Simulate the results of what would have happened if it would have\r
  49                   been active for all the time\r
  50                         - Grow a lot of grass and so on\r
  51         + Initially it is fine to send information about every active object\r
  52           to every player. Eventually it should be modified to only send info\r
  53           about the nearest ones.\r
  54                 + This was left to be done by the old system and it sends only the\r
  55                   nearest ones.\r
  56 \r
  57 Old, wild and random suggestions that probably won't be done:\r
  58 -------------------------------------------------------------\r
  59 \r
  60 SUGG: If player is on ground, mainly fetch ground-level blocks\r
  61 \r
  62 SUGG: Expose Connection's seqnums and ACKs to server and client.\r
  63       - This enables saving many packets and making a faster connection\r
  64           - This also enables server to check if client has received the\r
  65             most recent block sent, for example.\r
  66 SUGG: Add a sane bandwidth throttling system to Connection\r
  67 \r
  68 SUGG: More fine-grained control of client's dumping of blocks from\r
  69       memory\r
  70           - ...What does this mean in the first place?\r
  71 \r
  72 SUGG: A map editing mode (similar to dedicated server mode)\r
  73 \r
  74 SUGG: Transfer more blocks in a single packet\r
  75 SUGG: A blockdata combiner class, to which blocks are added and at\r
  76       destruction it sends all the stuff in as few packets as possible.\r
  77 SUGG: Make a PACKET_COMBINED which contains many subpackets. Utilize\r
  78       it by sending more stuff in a single packet.\r
  79           - Add a packet queue to RemoteClient, from which packets will be\r
  80             combined with object data packets\r
  81                 - This is not exactly trivial: the object data packets are\r
  82                   sometimes very big by themselves\r
  83           - This might not give much network performance gain though.\r
  84 \r
  85 SUGG: Precalculate lighting translation table at runtime (at startup)\r
  86       - This is not doable because it is currently hand-made and not\r
  87             based on some mathematical function.\r
  88                 - Note: This has been changing lately\r
  89 \r
  90 SUGG: A version number to blocks, which increments when the block is\r
  91       modified (node add/remove, water update, lighting update)\r
  92           - This can then be used to make sure the most recent version of\r
  93             a block has been sent to client, for example\r
  94 \r
  95 SUGG: Make the amount of blocks sending to client and the total\r
  96           amount of blocks dynamically limited. Transferring blocks is the\r
  97           main network eater of this system, so it is the one that has\r
  98           to be throttled so that RTTs stay low.\r
  99 \r
 100 SUGG: Meshes of blocks could be split into 6 meshes facing into\r
 101       different directions and then only those drawn that need to be\r
 102 \r
 103 SUGG: Background music based on cellular automata?\r
 104       http://www.earslap.com/projectslab/otomata\r
 105 \r
 106 SUGG: Simple light color information to air\r
 107 \r
 108 SUGG: Server-side objects could be moved based on nodes to enable very\r
 109       lightweight operation and simple AI\r
 110         - Not practical; client would still need to show smooth movement.\r
 111 \r
 112 SUGG: Make a system for pregenerating quick information for mapblocks, so\r
 113           that the client can show them as cubes before they are actually sent\r
 114           or even generated.\r
 115 \r
 116 SUGG: Erosion simulation at map generation time\r
 117     - This might be plausible if larger areas of map were pregenerated\r
 118           without lighting (which is slow)\r
 119         - Simulate water flows, which would carve out dirt fast and\r
 120           then turn stone into gravel and sand and relocate it.\r
 121         - How about relocating minerals, too? Coal and gold in\r
 122           downstream sand and gravel would be kind of cool\r
 123           - This would need a better way of handling minerals, mainly\r
 124                 to have mineral content as a separate field. the first\r
 125                 parameter field is free for this.\r
 126         - Simulate rock falling from cliffs when water has removed\r
 127           enough solid rock from the bottom\r
 128 \r
 129 SUGG: For non-mapgen FarMesh: Add a per-sector database to store surface\r
 130       stuff as simple flags/values\r
 131       - Light?\r
 132           - A building?\r
 133           And at some point make the server send this data to the client too,\r
 134           instead of referring to the noise functions\r
 135           - Ground height\r
 136           - Surface ground type\r
 137           - Trees?\r
 138 \r
 139 Gaming ideas:\r
 140 -------------\r
 141 \r
 142 - Aim for something like controlling a single dwarf in Dwarf Fortress\r
 143 - The player could go faster by a crafting a boat, or riding an animal\r
 144 - Random NPC traders. what else?\r
 145 \r
 146 Game content:\r
 147 -------------\r
 148 \r
 149 - When furnace is destroyed, move items to player's inventory\r
 150 - Add lots of stuff\r
 151 - Glass blocks\r
 152 - Growing grass, decaying leaves\r
 153         - This can be done in the active blocks I guess.\r
 154         - Lots of stuff can be done in the active blocks.\r
 155         - Uh, is there an active block list somewhere? I think not. Add it.\r
 156 - Breaking weak structures\r
 157         - This can probably be accomplished in the same way as grass\r
 158 - Player health points\r
 159         - When player dies, throw items on map (needs better item-on-map\r
 160           implementation)\r
 161 - Cobble to get mossy if near water\r
 162 - More slots in furnace source list, so that multiple ingredients\r
 163   are possible.\r
 164 - Keys to chests?\r
 165 \r
 166 - The Treasure Guard; a big monster with a hammer\r
 167         - The hammer does great damage, shakes the ground and removes a block\r
 168         - You can drop on top of it, and have some time to attack there\r
 169           before he shakes you off\r
 170 \r
 171 - Maybe the difficulty could come from monsters getting tougher in\r
 172   far-away places, and the player starting to need something from\r
 173   there when time goes by.\r
 174   - The player would have some of that stuff at the beginning, and\r
 175     would need new supplies of it when it runs out\r
 176 \r
 177 - A bomb\r
 178 - A spread-items-on-map routine for the bomb, and for dying players\r
 179 \r
 180 - Fighting:\r
 181   - Proper sword swing simulation\r
 182   - Player should get damage from colliding to a wall at high speed\r

 202       can be used\r
 203       - That is >500 vertices\r
 204           - This is not easy; all the MapBlocks close to the player would\r
 205             still need to be drawn separately and combining the blocks\r
 206                 would have to happen in a background thread\r
