  21 =============================== NOTES ==============================
  22 NOTE: Things starting with TODO are sometimes only suggestions.
  23
  24 NOTE: iostream.imbue(std::locale("C")) is very slow
  25 NOTE: Global locale is now set at initialization
  26
  27 NOTE: If VBO (EHM_STATIC) is used, remember to explicitly free the
  28       hardware buffer (it is not freed automatically)
  29
  30 NOTE: A random to-do list saved here as documentation:
  31 A list of "active blocks" in which stuff happens. (+=done)
  32         + Add a never-resetted game timer to the server
  33         + Add a timestamp value to blocks
  34         + The simple rule: All blocks near some player are "active"
  35         - Do stuff in real time in active blocks
  36                 + Handle objects
  37                 - Grow grass, delete leaves without a tree
  38                 - Spawn some mobs based on some rules
  39                 - Transform cobble to mossy cobble near water
  40                 - Run a custom script
  41                 - ...And all kinds of other dynamic stuff
  42         + Keep track of when a block becomes active and becomes inactive
  43         + When a block goes inactive:
  44                 + Store objects statically to block
  45                 + Store timer value as the timestamp
  46         + When a block goes active:
  47                 + Create active objects out of static objects
  48                 - Simulate the results of what would have happened if it would have
  49                   been active for all the time
  50                         - Grow a lot of grass and so on
  51         + Initially it is fine to send information about every active object
  52           to every player. Eventually it should be modified to only send info
  53           about the nearest ones.
  54                 + This was left to be done by the old system and it sends only the
  55                   nearest ones.

  65 Other things to note:
  66 - node.d = node.param0 (only in raw serialization; use getContent() otherwise)
  67 - node.param = node.param1
  68 - node.dir = node.param2
  69 - content_walkable(node.d) etc should be changed to
  70   content_features(node).walkable etc
  71 - Also check for lines that store the result of getContent to a 8-bit
  72   variable and fix them (result of getContent() must be stored in
  73   content_t, which is 16-bit)

  80
  81 Old, wild and random suggestions that probably won't be done:
  82 -------------------------------------------------------------
  83
  84 SUGG: If player is on ground, mainly fetch ground-level blocks
  85
  86 SUGG: Expose Connection's seqnums and ACKs to server and client.
  87       - This enables saving many packets and making a faster connection
  88           - This also enables server to check if client has received the
  89             most recent block sent, for example.
  90 SUGG: Add a sane bandwidth throttling system to Connection
  91
  92 SUGG: More fine-grained control of client's dumping of blocks from
  93       memory
  94           - ...What does this mean in the first place?
  95
  96 SUGG: A map editing mode (similar to dedicated server mode)
  97
  98 SUGG: Transfer more blocks in a single packet
  99 SUGG: A blockdata combiner class, to which blocks are added and at
 100       destruction it sends all the stuff in as few packets as possible.
 101 SUGG: Make a PACKET_COMBINED which contains many subpackets. Utilize
 102       it by sending more stuff in a single packet.
 103           - Add a packet queue to RemoteClient, from which packets will be
 104             combined with object data packets
 105                 - This is not exactly trivial: the object data packets are
 106                   sometimes very big by themselves
 107           - This might not give much network performance gain though.
 108
 109 SUGG: Precalculate lighting translation table at runtime (at startup)
 110       - This is not doable because it is currently hand-made and not
 111             based on some mathematical function.
 112                 - Note: This has been changing lately
 113
 114 SUGG: A version number to blocks, which increments when the block is
 115       modified (node add/remove, water update, lighting update)
 116           - This can then be used to make sure the most recent version of
 117             a block has been sent to client, for example
 118
 119 SUGG: Make the amount of blocks sending to client and the total
 120           amount of blocks dynamically limited. Transferring blocks is the
 121           main network eater of this system, so it is the one that has
 122           to be throttled so that RTTs stay low.
 123
 124 SUGG: Meshes of blocks could be split into 6 meshes facing into
 125       different directions and then only those drawn that need to be
 126
 127 SUGG: Background music based on cellular automata?
 128       http://www.earslap.com/projectslab/otomata
 129
 130 SUGG: Simple light color information to air
 131
 132 SUGG: Server-side objects could be moved based on nodes to enable very
 133       lightweight operation and simple AI
 134         - Not practical; client would still need to show smooth movement.
 135
 136 SUGG: Make a system for pregenerating quick information for mapblocks, so
 137           that the client can show them as cubes before they are actually sent
 138           or even generated.
 139
 140 SUGG: Erosion simulation at map generation time
 141     - This might be plausible if larger areas of map were pregenerated
 142           without lighting (which is slow)
 143         - Simulate water flows, which would carve out dirt fast and
 144           then turn stone into gravel and sand and relocate it.
 145         - How about relocating minerals, too? Coal and gold in
 146           downstream sand and gravel would be kind of cool
 147           - This would need a better way of handling minerals, mainly
 148                 to have mineral content as a separate field. the first
 149                 parameter field is free for this.
 150         - Simulate rock falling from cliffs when water has removed
 151           enough solid rock from the bottom
 152
 153 SUGG: For non-mapgen FarMesh: Add a per-sector database to store surface
 154       stuff as simple flags/values
 155       - Light?
 156           - A building?
 157           And at some point make the server send this data to the client too,
 158           instead of referring to the noise functions
 159           - Ground height
 160           - Surface ground type
 161           - Trees?
 162
 163 Gaming ideas:
 164 -------------
 165
 166 - Aim for something like controlling a single dwarf in Dwarf Fortress
 167 - The player could go faster by a crafting a boat, or riding an animal
 168 - Random NPC traders. what else?
 169
 170 Game content:
 171 -------------
 172
 173 - When furnace is destroyed, move items to player's inventory
 174 - Add lots of stuff
 175 - Glass blocks
 176 - Growing grass, decaying leaves
 177         - This can be done in the active blocks I guess.
 178         - Lots of stuff can be done in the active blocks.
 179         - Uh, is there an active block list somewhere? I think not. Add it.
 180 - Breaking weak structures
 181         - This can probably be accomplished in the same way as grass
 182 - Player health points
 183         - When player dies, throw items on map (needs better item-on-map
 184           implementation)
 185 - Cobble to get mossy if near water
 186 - More slots in furnace source list, so that multiple ingredients
 187   are possible.
 188 - Keys to chests?
 189
 190 - The Treasure Guard; a big monster with a hammer
 191         - The hammer does great damage, shakes the ground and removes a block
 192         - You can drop on top of it, and have some time to attack there
 193           before he shakes you off
 194
 195 - Maybe the difficulty could come from monsters getting tougher in
 196   far-away places, and the player starting to need something from
 197   there when time goes by.
 198   - The player would have some of that stuff at the beginning, and
 199     would need new supplies of it when it runs out
 200
 201 - A bomb
 202 - A spread-items-on-map routine for the bomb, and for dying players
 203
 204 - Fighting:
 205   - Proper sword swing simulation
 206   - Player should get damage from colliding to a wall at high speed

 222 Graphics:
 223 ---------
 224
 225 SUGG: Combine MapBlock's face caches to so big pieces that VBO
 226       can be used
 227       - That is >500 vertices
 228           - This is not easy; all the MapBlocks close to the player would
 229             still need to be drawn separately and combining the blocks
 230                 would have to happen in a background thread
 231
 232 SUGG: Make fetching sector's blocks more efficient when rendering
 233       sectors that have very large amounts of blocks (on client)
 234           - Is this necessary at all?
 235
 236 SUGG: Draw cubes in inventory directly with 3D drawing commands, so that
 237       animating them is easier.
 238
 239 SUGG: Option for enabling proper alpha channel for textures
 240
 241 TODO: Flowing water animation

 248       current one
 249
 250 TODO: Artificial (night) light could be more yellow colored than sunlight.
 251       - This is technically doable.
 252           - Also the actual colors of the textures could be made less colorful
 253             in the dark but it's a bit more difficult.
 254
 255 SUGG: Somehow make the night less colorful
 256
 257 TODO: Occlusion culling
 258       - At the same time, move some of the renderMap() block choosing code
 259         to the same place as where the new culling happens.
 260       - Shoot some rays per frame and when ready, make a new list of
 261             blocks for usage of renderMap and give it a new pointer to it.

 270       - Needs some input queues or something

 272             meshes takes so long
 273
 274 SUGG: Make morning and evening transition more smooth and maybe shorter
 275
 276 TODO: Don't update all meshes always on single node changes, but
 277       check which ones should be updated
 278           - implement Map::updateNodeMeshes() and the usage of it

 299   blocks? List the first saved block, maybe it explains.
 300   - It is probably caused by oscillating water
 301   - TODO: Investigate if this still happens (this is a very old one)
 302 * Make a small history check to transformLiquids to detect and log
 303   continuous oscillations, in such detail that they can be fixed.
