-=============================== 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.

-%s/\.d;/.getContent();/g

-%s/\(content_liquid\|content_flowing_liquid\|make_liquid_flowing\|content_pointable\)(\([^.]*\).d)/\1(\2.getContent())/g

-Other things to note:

-- node.d = node.param0 (only in raw serialization; use getContent() otherwise)

-- node.param = node.param1

-- node.dir = node.param2

-- content_walkable(node.d) etc should be changed to

-  content_features(node).walkable etc

-- Also check for lines that store the result of getContent to a 8-bit

-  variable and fix them (result of getContent() must be stored in

-  content_t, which is 16-bit)

-

-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: Mineral and ground material properties

-      - This way mineral ground toughness can be calculated with just

-	    some formula, as well as tool strengths. Sounds too.

-	  - There are TODOs in appropriate files: material.h, content_mapnode.h

-

-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

-TODO: Move mineral to param2, increment map serialization version, add

-      conversion

-

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

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

+      difference when block activates
+
+Map:
+----
+
+TODO: Mineral and ground material properties
+      - This way mineral ground toughness can be calculated with just
+	    some formula, as well as tool strengths. Sounds too.
+	  - There are TODOs in appropriate files: material.h, content_mapnode.h
+
+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
+TODO: Move mineral to param2, increment map serialization version, add
+      conversion
+
+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
