=============================== 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)
|
||||
|
||||
NOTE: A random to-do list saved here as documentation:
|
||||
A list of "active blocks" in which stuff happens. (+=done)
|
||||
+ Add a never-resetted game timer to the server
|
||||
+ Add a timestamp value to blocks
|
||||
+ The simple rule: All blocks near some player are "active"
|
||||
- Do stuff in real time in active blocks
|
||||
+ Handle objects
|
||||
- Grow grass, delete leaves without a tree
|
||||
- Spawn some mobs based on some rules
|
||||
- Transform cobble to mossy cobble near water
|
||||
- Run a custom script
|
||||
- ...And all kinds of other dynamic stuff
|
||||
+ Keep track of when a block becomes active and becomes inactive
|
||||
+ When a block goes inactive:
|
||||
+ Store objects statically to block
|
||||
+ Store timer value as the timestamp
|
||||
+ When a block goes active:
|
||||
+ Create active objects out of static objects
|
||||
- Simulate the results of what would have happened if it would have
|
||||
been active for all the time
|
||||
- Grow a lot of grass and so on
|
||||
+ Initially it is fine to send information about every active object
|
||||
to every player. Eventually it should be modified to only send info
|
||||
about the nearest ones.
|
||||
+ This was left to be done by the old system and it sends only the
|
||||
nearest ones.

||||

||||

|

|
||||
Old, wild and random suggestions that probably won't be done:
|
||||
-------------------------------------------------------------
|
||||
|
||||
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: Background music based on cellular automata?
|
||||
http://www.earslap.com/projectslab/otomata
|
||||
|
||||
SUGG: Simple light color information to air
|
||||
|
||||
SUGG: Server-side objects could be moved based on nodes to enable very
|
||||
lightweight operation and simple AI
|
||||
- Not practical; client would still need to show smooth movement.
|
||||
|
||||
SUGG: 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.
|
||||
|
||||
SUGG: Erosion simulation at map generation time
|
||||
- This might be plausible if larger areas of map were pregenerated
|
||||
without lighting (which is slow)
|
||||
- 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: For non-mapgen FarMesh: Add a per-sector database to store surface
|
||||
stuff as simple flags/values
|
||||
- Light?
|
||||
- A building?
|
||||
And at some point make the server send this data to the client too,
|
||||
instead of referring to the noise functions
|
||||
- Ground height
|
||||
- Surface ground type
|
||||
- Trees?
|
||||
|
||||
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
|
||||
|
||||
- Fighting:
|
||||
- Proper sword swing simulation
|
||||
- Player should get damage from colliding to a wall at high speed

Networking and serialization:
|

-----------------------------
|
||||
|

SUGG: Fix address to be ipv6 compatible
|

|
||||
User Interface:
|
||||
---------------
|
||||
|
||||
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?
|
||||
|
||||
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: Flowing water animation
|
||||
|
||||
TODO: A setting for enabling bilinear filtering for textures
|
||||
|
||||
TODO: Better control of draw_control.wanted_max_blocks
|
||||
|
||||
TODO: Further investigate the use of GPU lighting in addition to the
|
||||
current one
|
||||
|
||||
TODO: Artificial (night) light could be more yellow colored than sunlight.
|
||||
- This is technically doable.
|
||||
- Also the actual colors of the textures could be made less colorful
|
||||
in the dark but it's a bit more difficult.
|
||||
|
||||
SUGG: Somehow make the night less colorful
|
||||
|
||||
TODO: Occlusion culling
|
||||
- At the same time, move some of the renderMap() block choosing code
|
||||
to the same place as where the new culling happens.
|
||||
- Shoot some rays per frame and when ready, make a new list of
|
||||
blocks for usage of renderMap and give it a new pointer to it.
|
||||
|
||||
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
|
||||
|
||||
FIXME: When disconnected to the menu, memory is not freed properly
|
||||
|
||||
TODO: Investigate how much the mesh generator thread gets used when
|
||||
transferring map data
|
||||
|
||||
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
|
||||
- TODO: Investigate if this still happens (this is a very old one)
|
||||
* Make a small history check to transformLiquids to detect and log
|
||||
continuous oscillations, in such detail that they can be fixed.
|
||||
|
||||
FIXME: The new optimized map sending doesn't sometimes send enough blocks
|
||||
from big caves and such
|
||||
FIXME: Block send distance configuration does not take effect for some reason
|
||||

TODO: Finish the ActiveBlockModifier stuff and use it for something

||||
|
||||
Objects:
|
||||
--------
|
||||
|
||||
TODO: Get rid of MapBlockObjects and use only ActiveObjects
|
||||
- Skipping the MapBlockObject data is nasty - there is no "total
|
||||
length" stored; have to make a SkipMBOs function which contains
|
||||
enough of the current code to skip them properly.
|
||||
|
||||
SUGG: MovingObject::move and Player::move are basically the same.
|
||||
combine them.
|
||||
- NOTE: This is a bit tricky because player has the sneaking ability
|
||||
- NOTE: Player::move is more up-to-date.
|
||||
- NOTE: There is a simple move implementation now in collision.{h,cpp}
|
||||
- NOTE: MovingObject will be deleted (MapBlockObject)
|
||||
|
||||
TODO: Add a long step function to objects that is called with the time
|

Map:
|

TODO: Flowing water to actually contain flow direction information

Misc. stuff:
|
||||
------------

TODO: Protocol version field
|

SUGG: Restart irrlicht completely when coming back to main menu from game.
|

- This gets rid of everything that is stored in irrlicht's caches.
|

- This might be needed for texture pack selection in menu

|
||||
- Better handling of Ctrl-C on POSIX systems
|
||||
|
