=============================== NOTES ==============================
NOTE: Things starting with TODO are sometimes only suggestions.
NOTE: iostream.imbue(std::locale("C")) is very slow
NOTE: Global locale is now set at initialization
NOTE: If VBO (EHM_STATIC) is used, remember to explicitly free the
hardware buffer (it is not freed automatically)
Random suggeestions (AKA very old suggestions that haven't been done):
----------------------------------------------------------------------
SUGG: Fix address to be ipv6 compatible
SUGG: If player is on ground, mainly fetch ground-level blocks
SUGG: Expose Connection's seqnums and ACKs to server and client.
- This enables saving many packets and making a faster connection
- This also enables server to check if client has received the
most recent block sent, for example.
SUGG: Add a sane bandwidth throttling system to Connection
SUGG: More fine-grained control of client's dumping of blocks from
memory
- ...What does this mean in the first place?
SUGG: A map editing mode (similar to dedicated server mode)
SUGG: Transfer more blocks in a single packet
SUGG: A blockdata combiner class, to which blocks are added and at
destruction it sends all the stuff in as few packets as possible.
SUGG: Make a PACKET_COMBINED which contains many subpackets. Utilize
it by sending more stuff in a single packet.
- Add a packet queue to RemoteClient, from which packets will be
combined with object data packets
- This is not exactly trivial: the object data packets are
sometimes very big by themselves
- This might not give much network performance gain though.
SUGG: Precalculate lighting translation table at runtime (at startup)
- This is not doable because it is currently hand-made and not
based on some mathematical function.
- Note: This has been changing lately
SUGG: A version number to blocks, which increments when the block is
modified (node add/remove, water update, lighting update)
- This can then be used to make sure the most recent version of
a block has been sent to client, for example
SUGG: Make the amount of blocks sending to client and the total
amount of blocks dynamically limited. Transferring blocks is the
main network eater of this system, so it is the one that has
to be throttled so that RTTs stay low.
SUGG: Meshes of blocks could be split into 6 meshes facing into
different directions and then only those drawn that need to be
SUGG: Calculate lighting per vertex to get a lighting effect like in
bartwe's game
SUGG: Background music based on cellular automata?

Gaming ideas:
-------------
- Aim for something like controlling a single dwarf in Dwarf Fortress
- The player could go faster by a crafting a boat, or riding an animal
- Random NPC traders. what else?
Game content:
-------------
- When furnace is destroyed, move items to player's inventory
- Add lots of stuff
- Glass blocks
- Growing grass, decaying leaves
- This can be done in the active blocks I guess.
- Lots of stuff can be done in the active blocks.
- Uh, is there an active block list somewhere? I think not. Add it.
- Breaking weak structures
- This can probably be accomplished in the same way as grass
- Player health points
- When player dies, throw items on map (needs better item-on-map
implementation)
- Cobble to get mossy if near water
- More slots in furnace source list, so that multiple ingredients
are possible.
- Keys to chests?
- The Treasure Guard; a big monster with a hammer
- The hammer does great damage, shakes the ground and removes a block
- You can drop on top of it, and have some time to attack there
before he shakes you off
- Maybe the difficulty could come from monsters getting tougher in
far-away places, and the player starting to need something from
there when time goes by.
- The player would have some of that stuff at the beginning, and
would need new supplies of it when it runs out
- A bomb
- A spread-items-on-map routine for the bomb, and for dying players
Documentation:
--------------
Build system / running:
-----------------------
Networking and serialization:
-----------------------------
TODO: Get rid of GotSplitPacketException
GUI:
----
TODO: Configuration menu, at least for keys
Graphics:
---------
SUGG: Combine MapBlock's face caches to so big pieces that VBO
can be used
- That is >500 vertices
- This is not easy; all the MapBlocks close to the player would
still need to be drawn separately and combining the blocks
would have to happen in a background thread
SUGG: Make fetching sector's blocks more efficient when rendering
sectors that have very large amounts of blocks (on client)
- Is this necessary at all?
TODO: Flowing water animation
SUGG: Draw cubes in inventory directly with 3D drawing commands, so that
animating them is easier.
SUGG: Option for enabling proper alpha channel for textures
TODO: A setting for enabling bilinear filtering for textures
TODO: Better control of draw_control.wanted_max_blocks
TODO: Get player texture (and some others) from the specified texture
directory
Configuration:
--------------
Client:
-------
TODO: Untie client network operations from framerate
- Needs some input queues or something
- This won't give much performance boost because calculating block
meshes takes so long
SUGG: Make morning and evening transition more smooth and maybe shorter
TODO: Don't update all meshes always on single node changes, but
check which ones should be updated
- implement Map::updateNodeMeshes() and the usage of it
- It will give almost always a 4x boost in mesh update performance.
- A weapon engine
- Tool/weapon visualization
Server:
-------
SUGG: Make an option to the server to disable building and digging near
the starting position
FIXME: Server sometimes goes into some infinite PeerNotFoundException loop
* Fix the problem with the server constantly saving one or a few
blocks? List the first saved block, maybe it explains.
- It is probably caused by oscillating water
* Make a small history check to transformLiquids to detect and log
continuous oscillations, in such detail that they can be fixed.
Objects:
--------
TODO: Get rid of MapBlockObjects and use ActiveObjects
SUGG: MovingObject::move and Player::move are basically the same.
combine them.
- NOTE: Player::move is more up-to-date.
- NOTE: There is a simple move implementation now in collision.{h,cpp}
Map:
----
TODO: Mineral and ground material properties
- This way mineral ground toughness can be calculated with just
some formula, as well as tool strengths
TODO: Flowing water to actually contain flow direction information
- There is a space for this - it just has to be implemented.
SUGG: Erosion simulation at map generation time
- Simulate water flows, which would carve out dirt fast and
then turn stone into gravel and sand and relocate it.
- How about relocating minerals, too? Coal and gold in
downstream sand and gravel would be kind of cool
- This would need a better way of handling minerals, mainly
to have mineral content as a separate field. the first
parameter field is free for this.
- Simulate rock falling from cliffs when water has removed
enough solid rock from the bottom
SUGG: Try out the notch way of generating maps, that is, make bunches
of low-res 3d noise and interpolate linearly.
Mapgen v2:
* Possibly add some kind of erosion and other stuff
* Better water generation (spread it to underwater caverns but don't
fill dungeons that don't touch big water masses)
* When generating a chunk and the neighboring chunk doesn't have mud
and stuff yet and the ground is fairly flat, the mud will flow to
the other chunk making nasty straight walls when the other chunk
is generated. Fix it. Maybe just a special case if the ground is
flat?
Misc. stuff:
------------
* Make an "environment metafile" to store at least time of day
* Move digging property stuff from material.{h,cpp} to mapnode.cpp...
- Or maybe move content_features to material.{h,cpp}?
* Maybe:
Make a system for pregenerating quick information for mapblocks, so
that the client can show them as cubes before they are actually sent
or even generated.
Making it more portable:
------------------------
* Some MSVC: std::sto* are defined without a namespace and collide
with the ones in utility.h
