=============================== NOTES ==============================
NOTE: Things starting with TODO are sometimes only suggestions.
NOTE: VBO cannot be turned on for fast-changing stuff because there
is an apparanet memory leak in irrlicht when using it (not sure)
NOTE: iostream.imbue(std::locale("C")) is very slow
NOTE: Global locale is now set at initialization
SUGG: Fix address to be ipv6 compatible
FIXME: When a new sector is generated, it may change the ground level
of it's and it's neighbors border that two blocks that are
above and below each other and that are generated before and
after the sector heightmap generation (order doesn't matter),
can have a small gap between each other at the border.
SUGGESTION: Use same technique for sector heightmaps as what we're
using for UnlimitedHeightmap? (getting all neighbors
when generating)
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: If player is on ground, mainly fetch ground-level blocks
SUGG: Fetch stuff mainly from the viewing direction
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: Add a time value to the param of footstepped grass and check it
against a global timer when a block is accessed, to make old
steps fade away.
SUGG: Make a copy of close-range environment on client for showing
on screen, with minimal mutexes to slow down the main loop
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
SUGG: Split MapBlockObject serialization to to-client and to-disk
- This will allow saving ages of rats on disk but not sending
them to clients
SUGG: Implement lighting using VoxelManipulator
- Would it be significantly faster?
FIXME: Rats somehow go underground sometimes (you can see it in water)
- Does their position get saved to a border value or something?
- Does this happen anymore?
SUGG: MovingObject::move and Player::move are basically the same.
combine them.
SUGG: Implement a "Fast check queue" (a queue with a map for checking
if something is already in it)
- Use it in active block queue in water flowing
SUGG: Signs could be done in the same way as torches. For this, blocks
need an additional metadata field for the texts
- This is also needed for item container chests
SUGG: Precalculate lighting translation table at runtime (at startup)
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
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.
TODO: Untie client network operations from framerate
- Needs some input queues or something
- Not really necessary?
TODO: Combine MapBlock's face caches to so big pieces that VBO
gets used
- That is >500 vertices
TODO: Better dungeons
TODO: Cliffs, arcs
TODO: Startup and configuration menu
TODO: There are some lighting-related todos and fixmes in
ServerMap::emergeBlock
TODO: Proper handling of spawning place (try to find something that
is not in the middle of an ocean (some land to stand on at
least) and save it in map config.
TODO: Players to only be hidden when the client quits.
TODO: - Players to be saved on disk, with inventory
TODO: Players to be saved as text in map/players/<name>
TODO: Player inventory to be saved on disk
TODO: Make fetching sector's blocks more efficient when rendering
sectors that have very large amounts of blocks (on client)
TODO: Make the video backend selectable
Block object server side:
- A "near blocks" buffer, in which some nearby blocks are stored.
- For all blocks in the buffer, objects are stepped(). This
means they are active.
- TODO: A global active buffer is needed for the server
- TODO: A timestamp to blocks
- TODO: All blocks going in and out of the buffer are recorded.
- TODO: For outgoing blocks, timestamp is written.
- TODO: For incoming blocks, time difference is calculated and
objects are stepped according to it.
TODO: Copy the text of the last picked sign to inventory in creative
mode
TODO: Get rid of GotSplitPacketException
TODO: Check what goes wrong with caching map to disk (Kray)
TODO: Remove LazyMeshUpdater. It is not used as supposed.
TODO: TOSERVER_LEAVE
TODO: Better handling of objects and mobs
- Scripting?
- There has to be some way to do it with less spaghetti code
- Make separate classes for client and server
- Client should not discriminate between blocks, server should
- Make other players utilize the same framework
TODO: Draw big amounts of torches better (that is, throw them in the
same meshbuffer (can the meshcollector class be used?))
TODO: Check if the usage of Client::isFetchingBlocks() in
updateViewingRange() actually does something
Doing now:
======================================================================
TODO: Convert the text input system to use a modal menu... or something
======================================================================

Setting this to 1 enables a special camera mode that forces
the renderers to think that the camera statically points from
