=============================== 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.
NOTE: Seeds in 1260:6c77e7dbfd29:

Spawns you on a small sand island with a surface dungeon

Enormous jungle + a surface dungeon at ~(250,0,0)
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
Documentation:
--------------
Build system / running:
-----------------------
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
Environment:
------------
TODO: Add proper hooks to when adding and removing active blocks
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
difference when block activates
Map:
----
TODO: Flowing water to actually contain flow direction information
- There is a space for this - it just has to be implemented.
TODO: Consider smoothening cave floors after generating them
TODO: Fix make_tree, make_* to use seed-position-consistent pseudorandom
- delta also
Misc. stuff:
------------
TODO: Make sure server handles removing grass when a block is placed (etc)
- The client should not do it by itself
- NOTE: I think nobody does it currently...
TODO: Block cube placement around player's head
TODO: Protocol version field
TODO: Think about using same bits for material for fences and doors, for
example
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
TODO: Merge bahamada's audio stuff (clean patch available)
Making it more portable:
------------------------
Stuff to do before release:
