=============================== 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
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
in a way that doesn't make the player jump to the right place
immediately when the server sends a new position
TODO: There are some lighting-related todos and fixmes in
ServerMap::emergeBlock
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: 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.
SUGG: Set server to automatically find a good spawning place in some
place where there is water and land.
- Map to have a getWalkableNear(p)
- Is this a good idea? It's part of the game to find a good place.
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.
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.
TODO: 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?
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.
TODO: Server to load starting inventory from disk
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>
SUGG: A map editing mode (similar to dedicated server mode)
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: 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
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.
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
- Needs some input queues or something
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
TODO: Get rid of GotSplitPacketException
SUGG: Implement lighting using VoxelManipulator
- Would it be significantly faster?
TODO: Check what goes wrong with caching map to disk (Kray)
TODO: Remove LazyMeshUpdater. It is not used as supposed.
FIXME: Rats somehow go underground sometimes (you can see it in water)
- Does their position get saved to a border value or something?
SUGG: MovingObject::move and Player::move are basically the same.
combine them.
TODO: Transfer sign texts as metadata of block and not as data of
object
Doing now:
======================================================================
Water dynamics pseudo-code (block = MapNode):
SUGG: Create separate flag table in VoxelManipulator to allow fast
clearing of "modified" flags
neighborCausedPressure(pos):
pressure = 0
dirs = {down, left, right, back, front, up}
for d in dirs:
pos2 = pos + d
p = block_at(pos2).pressure
if d.Y == 1 and p > min:
p -= 1
if d.Y == -1 and p < max:
p += 1
if p > pressure:
pressure = p
return pressure
# This should somehow update all changed pressure values
# in an unknown body of water
updateWaterPressure(pos):
TODO
FIXME: This goes in an indefinite loop when there is an underwater
chamber like this:
#111######
#222##22##
#33333333x<- block removed from here
##########
#111######
#222##22##
#3333333x1

#111######
#222##22##
#333333x11
##########
#111######
#222##2x##
#333333333
##########
#111######
#222##x2##
#333333333
##########
Now, consider moving to the last block not allowed.
Consider it a 3D case with a depth of 2. We're now at this situation.
Note the additional blocking ## in the second depth plane.
z=1 z=2
#111###### #111######
#222##x2## #222##22##
#333333333 #33333##33

########## ##########
#111###### #111######
#222##22## #222##2x##
#333333333 #33333##33
########## ##########
Now there is nowhere to go, without going to an already visited block,
but the pressure calculated in here from neighboring blocks is >= 2,
so it is not the final ending.
We will back up to a state where there is somewhere to go to.
It is this state:
#111###### #111######
#222##22## #222##22##
#333333x33 #33333##33
########## ##########
Then just go on, avoiding already visited blocks:
#111###### #111######
#222##22## #222##22##
#33333x333 #33333##33
########## ##########
#111###### #111######

"Blob". the air bubble finally got out of the water.
Then return recursively to a state where there is air next to water,
clear the visit flags and feed the neighbor of the water recursively
to the algorithm.
