=============================== NOTES ==============================
NOTE: VBO cannot be turned on for fast-changing stuff because there
is an apparanet memory leak in irrlicht when using it
SUGGESTION: add a second lighting value to the MS nibble of param of
air to tell how bright the air node is when there is no sunlight.
When day changes to night, these two values can be interpolated.
TODO: Fix address to be ipv6 compatible
TODO: ESC Pause mode in which the cursor is not kept at the center of window.
TODO: Stop player if focus of window is taken away (go to pause mode)
TODO: Optimize and fix makeFastFace or whatever it's called
- Face calculation is the source of CPU usage on the client
SUGGESTION: The client will calculate and send lighting changes and
the server will randomly check some of them and kick the client out
if it fails to calculate them right.
- Actually, it could just start ignoring them and calculate them
itself.
SUGGESTION: Combine MapBlock's face caches to so big pieces that VBO
gets used
- That is >500 vertices
TODO: Better dungeons
TODO: There should be very slight natural caves also, starting from
only a straightened-up cliff
TODO: Changing of block with mouse wheel or something
TODO: Menus
TODO: Mobs
- Server:
- One single map container with ids as keys
- Client:
- ?
TODO: - Keep track of the place of the mob in the last few hundreth's
of a second - then, if a player hits it, take the value that is
avg_rtt/2 before the moment the packet is received.
TODO: - Scripting
SUGGESTION: Modify client to calculate single changes asynchronously
TODO: Moving players more smoothly. Calculate moving animation from
data sent by server.
TODO: There are some lighting-related todos and fixmes in
ServerMap::emergeBlock
TODO: Make a dirt node and use it under water
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)
TODO: Set server to automatically find a good spawning place in some
place where there is water and land.
- Map to have a getWalkableNear(p)
TODO: 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.
TODO: If player is on ground, mainly fetch ground-level blocks
TODO: Fetch stuff mainly from the viewing direction
TODO: 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 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.
FIXME: There still are *some* tiny glitches in lighting as seen from
the client side. The server calculates them right but sometimes
they don't get transferred properly.
- Server probably checks that a block is not sent, then continues
to sending it, then the emerge thread marks it as unsent and then
the sender sends the block as it was before emerging?
TODO: How about adding a "revision" field to MapBlocks?
TODO: More fine-grained control of client's dumping of blocks from
memory
TODO: Somehow prioritize the sending of blocks and combine the block
send queue lengths
- Take two blocks to be sent next from each client and assign
a priority value to them
- Priority is the same as distance from player
- Take the highest priority ones and send them. Send as many as
fits in the global send queue maximum length (sum of lengths
of client queues)
TODO: 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.
FIXME: There is a bug that sometimes the EmergeThread bumps to
the client's emerge counter being already 0, and also the
sending queue size of the client can float to 1 or 2, which
stops the map from loading at all.
- A quick hack could be applied to ignore the error of
being at 0 and timing out old entries
SUGG: Make client send GOTBLOCKS before updating meshes
TODO: Server to load starting inventory from disk
NOTE: iostream.imbue(std::locale("C")) is very slow
NOTE: Global locale is now set at initialization
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>
SUGGESTION: A map editing mode (similar to dedicated server mode)
TODO: Maybe: Create a face calculation queue on the client that is
processed in a separate thread
TODO: Make client's mesh updates to happen in a thread similar to
server's EmergeThread.
- This is not really needed, mesh update is really fast
- Instead, the lighting update can be slow
- So, this todo is not really a todo. It is a not-todo.
SUGG: Make server to send all modified blocks after a node change
after all the stuff including lighting have been updated
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 All blocks going in and out of the buffer are recorded.
- TODO For outgoing blocks, a timestamp is written.
- TODO For incoming blocks, the time difference is calculated and
objects are stepped according to it.
TODO: A timestamp to blocks
TODO: Add config parameters for server's sending and generating distance
TODO: Copy the text of the last picked sign to inventory in creative
mode
TODO: Untie client network operations from framerate
SUGG: Make a copy of close-range environment on client for showing
on screen, with minimal mutexes to slow the main loop down
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
TODO: Fix the long-lived Server Block Emerge Jam bug
- Is it related to the client deleting blocks?
Doing now:
