- =============================== NOTES ==============================\r
- NOTE: Things starting with TODO are sometimes only suggestions.\r
- \r
- NOTE: iostream.imbue(std::locale("C")) is very slow\r
- NOTE: Global locale is now set at initialization\r
- \r
- NOTE: If VBO (EHM_STATIC) is used, remember to explicitly free the\r
- hardware buffer (it is not freed automatically)\r
- \r
- NOTE: A random to-do list saved here as documentation:\r
- A list of "active blocks" in which stuff happens. (+=done)\r
- + Add a never-resetted game timer to the server\r
- + Add a timestamp value to blocks\r
- + The simple rule: All blocks near some player are "active"\r
- - Do stuff in real time in active blocks\r
- + Handle objects\r
- - Grow grass, delete leaves without a tree\r
- - Spawn some mobs based on some rules\r
- - Transform cobble to mossy cobble near water\r
- - Run a custom script\r
- - ...And all kinds of other dynamic stuff\r
- + Keep track of when a block becomes active and becomes inactive\r
- + When a block goes inactive:\r
- + Store objects statically to block\r
- + Store timer value as the timestamp\r
- + When a block goes active:\r
- + Create active objects out of static objects\r
- - Simulate the results of what would have happened if it would have\r
- been active for all the time\r
- - Grow a lot of grass and so on\r
- + Initially it is fine to send information about every active object\r
- to every player. Eventually it should be modified to only send info\r
- about the nearest ones.\r
- + This was left to be done by the old system and it sends only the\r
- nearest ones.\r
- \r
- Old, wild and random suggestions that probably won't be done:\r
- -------------------------------------------------------------\r
- \r
- SUGG: If player is on ground, mainly fetch ground-level blocks\r
- \r
- SUGG: Expose Connection's seqnums and ACKs to server and client.\r
- - This enables saving many packets and making a faster connection\r
- - This also enables server to check if client has received the\r
- most recent block sent, for example.\r
- SUGG: Add a sane bandwidth throttling system to Connection\r
- \r
- SUGG: More fine-grained control of client's dumping of blocks from\r
- memory\r
- - ...What does this mean in the first place?\r
- \r
- SUGG: A map editing mode (similar to dedicated server mode)\r
- \r
- SUGG: Transfer more blocks in a single packet\r
- SUGG: A blockdata combiner class, to which blocks are added and at\r
- destruction it sends all the stuff in as few packets as possible.\r
- SUGG: Make a PACKET_COMBINED which contains many subpackets. Utilize\r
- it by sending more stuff in a single packet.\r
- - Add a packet queue to RemoteClient, from which packets will be\r
- combined with object data packets\r
- - This is not exactly trivial: the object data packets are\r
- sometimes very big by themselves\r
- - This might not give much network performance gain though.\r
- \r
- SUGG: Precalculate lighting translation table at runtime (at startup)\r
- - This is not doable because it is currently hand-made and not\r
- based on some mathematical function.\r
- - Note: This has been changing lately\r
- \r
- SUGG: A version number to blocks, which increments when the block is\r
- modified (node add/remove, water update, lighting update)\r
- - This can then be used to make sure the most recent version of\r
- a block has been sent to client, for example\r
- \r
- SUGG: Make the amount of blocks sending to client and the total\r
- amount of blocks dynamically limited. Transferring blocks is the\r
- main network eater of this system, so it is the one that has\r
- to be throttled so that RTTs stay low.\r
- \r
- SUGG: Meshes of blocks could be split into 6 meshes facing into\r
- different directions and then only those drawn that need to be\r
- \r
- SUGG: Background music based on cellular automata?\r
- http://www.earslap.com/projectslab/otomata\r
- \r
- SUGG: Simple light color information to air\r
- \r
- SUGG: Server-side objects could be moved based on nodes to enable very\r
- lightweight operation and simple AI\r
- - Not practical; client would still need to show smooth movement.\r
- \r
- SUGG: Make a system for pregenerating quick information for mapblocks, so\r
- that the client can show them as cubes before they are actually sent\r
- or even generated.\r
- \r
- SUGG: Erosion simulation at map generation time\r
- - This might be plausible if larger areas of map were pregenerated\r
- without lighting (which is slow)\r
- - Simulate water flows, which would carve out dirt fast and\r
- then turn stone into gravel and sand and relocate it.\r
- - How about relocating minerals, too? Coal and gold in\r
- downstream sand and gravel would be kind of cool\r
- - This would need a better way of handling minerals, mainly\r
- to have mineral content as a separate field. the first\r
- parameter field is free for this.\r
- - Simulate rock falling from cliffs when water has removed\r
- enough solid rock from the bottom\r
- \r
- SUGG: For non-mapgen FarMesh: Add a per-sector database to store surface\r
- stuff as simple flags/values\r
- - Light?\r
- - A building?\r
- And at some point make the server send this data to the client too,\r
- instead of referring to the noise functions\r
- - Ground height\r
- - Surface ground type\r
- - Trees?\r
- \r
- Gaming ideas:\r
- -------------\r
- \r
- - Aim for something like controlling a single dwarf in Dwarf Fortress\r
- - The player could go faster by a crafting a boat, or riding an animal\r
- - Random NPC traders. what else?\r
- \r
- Game content:\r
- -------------\r
- \r
- - When furnace is destroyed, move items to player's inventory\r
- - Add lots of stuff\r
- - Glass blocks\r
- - Growing grass, decaying leaves\r
- - This can be done in the active blocks I guess.\r
- - Lots of stuff can be done in the active blocks.\r
- - Uh, is there an active block list somewhere? I think not. Add it.\r
- - Breaking weak structures\r
- - This can probably be accomplished in the same way as grass\r
- - Player health points\r
- - When player dies, throw items on map (needs better item-on-map\r
- implementation)\r
- - Cobble to get mossy if near water\r
- - More slots in furnace source list, so that multiple ingredients\r
- are possible.\r
- - Keys to chests?\r
- \r
- - The Treasure Guard; a big monster with a hammer\r
- - The hammer does great damage, shakes the ground and removes a block\r
- - You can drop on top of it, and have some time to attack there\r
- before he shakes you off\r
- \r
- - Maybe the difficulty could come from monsters getting tougher in\r
- far-away places, and the player starting to need something from\r
- there when time goes by.\r
- - The player would have some of that stuff at the beginning, and\r
- would need new supplies of it when it runs out\r
- \r
- - A bomb\r
- - A spread-items-on-map routine for the bomb, and for dying players\r
- \r
- - Fighting:\r
- - Proper sword swing simulation\r
- - Player should get damage from colliding to a wall at high speed\r
- \r
- Documentation:\r
- --------------\r
- \r
- Build system / running:\r
- -----------------------\r
- \r
- Networking and serialization:\r
- -----------------------------\r
- \r
- SUGG: Fix address to be ipv6 compatible\r
- \r
- User Interface:\r
- ---------------\r
- \r
- Graphics:\r
- ---------\r
- \r
- SUGG: Combine MapBlock's face caches to so big pieces that VBO\r
- can be used\r
- - That is >500 vertices\r
- - This is not easy; all the MapBlocks close to the player would\r
- still need to be drawn separately and combining the blocks\r
- would have to happen in a background thread\r
- \r
- SUGG: Make fetching sector's blocks more efficient when rendering\r
- sectors that have very large amounts of blocks (on client)\r
- - Is this necessary at all?\r
- \r
- SUGG: Draw cubes in inventory directly with 3D drawing commands, so that\r
- animating them is easier.\r
- \r
- SUGG: Option for enabling proper alpha channel for textures\r
- \r
- TODO: Flowing water animation\r
- \r
- TODO: A setting for enabling bilinear filtering for textures\r
- \r
- TODO: Better control of draw_control.wanted_max_blocks\r
- \r
- TODO: Further investigate the use of GPU lighting in addition to the\r
- current one\r
- \r
- TODO: Artificial (night) light could be more yellow colored than sunlight.\r
- - This is technically doable.\r
- - Also the actual colors of the textures could be made less colorful\r
- in the dark but it's a bit more difficult.\r
- \r
- SUGG: Somehow make the night less colorful\r
- \r
- TODO: Occlusion culling\r
- - At the same time, move some of the renderMap() block choosing code\r
- to the same place as where the new culling happens.\r
- - Shoot some rays per frame and when ready, make a new list of\r
- blocks for usage of renderMap and give it a new pointer to it.\r
- \r
- Configuration:\r
- --------------\r
- \r
- Client:\r
- -------\r
- \r
- TODO: Untie client network operations from framerate\r
- - Needs some input queues or something\r
- - This won't give much performance boost because calculating block\r
- meshes takes so long\r
- \r
- SUGG: Make morning and evening transition more smooth and maybe shorter\r
- \r
- TODO: Don't update all meshes always on single node changes, but\r
- check which ones should be updated\r
- - implement Map::updateNodeMeshes() and the usage of it\r
- - It will give almost always a 4x boost in mesh update performance.\r
- \r
- - A weapon engine\r
- \r
- - Tool/weapon visualization\r
- \r
- FIXME: When disconnected to the menu, memory is not freed properly\r
- \r
- TODO: Investigate how much the mesh generator thread gets used when\r
- transferring map data\r
- \r
- Server:\r
- -------\r
- \r
- SUGG: Make an option to the server to disable building and digging near\r
- the starting position\r
- \r
- FIXME: Server sometimes goes into some infinite PeerNotFoundException loop\r
- \r
- * Fix the problem with the server constantly saving one or a few\r
- blocks? List the first saved block, maybe it explains.\r
- - It is probably caused by oscillating water\r
- - TODO: Investigate if this still happens (this is a very old one)\r
- * Make a small history check to transformLiquids to detect and log\r
- continuous oscillations, in such detail that they can be fixed.\r
- \r
- FIXME: The new optimized map sending doesn't sometimes send enough blocks\r
- from big caves and such\r
- FIXME: Block send distance configuration does not take effect for some reason\r
- \r
- Environment:\r
- ------------\r
- \r
- TODO: Add proper hooks to when adding and removing active blocks\r
- \r
- TODO: Finish the ActiveBlockModifier stuff and use it for something\r
- \r
- Objects:\r
- --------\r
- \r
- TODO: Get rid of MapBlockObjects and use only ActiveObjects\r
- - Skipping the MapBlockObject data is nasty - there is no "total\r
- length" stored; have to make a SkipMBOs function which contains\r
- enough of the current code to skip them properly.\r
- \r
- SUGG: MovingObject::move and Player::move are basically the same.\r
- combine them.\r
- - NOTE: This is a bit tricky because player has the sneaking ability\r
- - NOTE: Player::move is more up-to-date.\r
- - NOTE: There is a simple move implementation now in collision.{h,cpp}\r
- - NOTE: MovingObject will be deleted (MapBlockObject)\r
- \r
- TODO: Add a long step function to objects that is called with the time\r
- difference when block activates\r
- \r
- Map:\r
- ----\r
- \r
- TODO: Mineral and ground material properties\r
- - This way mineral ground toughness can be calculated with just\r
- some formula, as well as tool strengths\r
- - There are TODOs in appropriate files: material.h, content_mapnode.h\r
- \r
- TODO: Flowing water to actually contain flow direction information\r
- - There is a space for this - it just has to be implemented.\r
- \r
- TODO: Consider smoothening cave floors after generating them\r
- \r
- Misc. stuff:\r
- ------------\r
- TODO: Make sure server handles removing grass when a block is placed (etc)\r
- - The client should not do it by itself\r
- - NOTE: I think nobody does it currently...\r
- TODO: Block cube placement around player's head\r
- TODO: Protocol version field\r
- TODO: Think about using same bits for material for fences and doors, for\r
- example\r
- TODO: Move mineral to param2, increment map serialization version, add\r
- conversion\r
- \r
- TODO: Restart irrlicht completely when coming back to main menu from game.\r
- - This gets rid of everything that is stored in irrlicht's caches.\r
- \r
- TODO: Merge bahamada's audio stuff (clean patch available)\r
- \r
- TODO: Merge key configuration menu (no clean patch available)\r
- \r
- Making it more portable:\r
- ------------------------\r
- \r
- Stuff to do before release:\r

+ =============================== 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.
+
+ Vim conversion regexpes for moving to extended content type storage:
+ %s/\(\.\|->\)d \([!=]=\)/\1getContent() \2/g
+ %s/content_features(\([^.]*\)\.d)/content_features(\1)/g

+ %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

+
+ 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.
+ - This might be needed for texture pack selection in menu
+
+ TODO: Merge bahamada's audio stuff (clean patch available)
+
+ TODO: Move content_features to mapnode_content_features.{h,cpp} or so
+
+ Making it more portable:
