21 =============================== NOTES ==============================
22 NOTE: Things starting with TODO are sometimes only suggestions.
24 NOTE: iostream.imbue(std::locale("C")) is very slow
25 NOTE: Global locale is now set at initialization
27 NOTE: If VBO (EHM_STATIC) is used, remember to explicitly free the
28 hardware buffer (it is not freed automatically)
30 NOTE: A random to-do list saved here as documentation:
31 A list of "active blocks" in which stuff happens. (+=done)
32 + Add a never-resetted game timer to the server
33 + Add a timestamp value to blocks
34 + The simple rule: All blocks near some player are "active"
35 - Do stuff in real time in active blocks
37 - Grow grass, delete leaves without a tree
38 - Spawn some mobs based on some rules
39 - Transform cobble to mossy cobble near water
41 - ...And all kinds of other dynamic stuff
42 + Keep track of when a block becomes active and becomes inactive
43 + When a block goes inactive:
44 + Store objects statically to block
45 + Store timer value as the timestamp
46 + When a block goes active:
47 + Create active objects out of static objects
48 - Simulate the results of what would have happened if it would have
49 been active for all the time
50 - Grow a lot of grass and so on
51 + Initially it is fine to send information about every active object
52 to every player. Eventually it should be modified to only send info
53 about the nearest ones.
54 + This was left to be done by the old system and it sends only the
57 Vim conversion regexpes for moving to extended content type storage:
58 %s/\(\.\|->\)d \([!=]=\)/\1getContent() \2/g
59 %s/content_features(\([^.]*\)\.d)/content_features(\1)/g
60 %s/\(\.\|->\)d = \([^;]*\);/\1setContent(\2);/g
61 %s/\(getNodeNoExNoEmerge([^)]*)\)\.d/\1.getContent()/g
62 %s/\(getNodeNoExNoEmerge(.*)\)\.d/\1.getContent()/g
63 %s/\.d;/.getContent();/g
64 %s/\(content_liquid\|content_flowing_liquid\|make_liquid_flowing\|content_pointable\)(\([^.]*\).d)/\1(\2.getContent())/g
66 - node.d = node.param0 (only in raw serialization; use getContent() otherwise)
67 - node.param = node.param1
68 - node.dir = node.param2
69 - content_walkable(node.d) etc should be changed to
70 content_features(node).walkable etc
71 - Also check for lines that store the result of getContent to a 8-bit
72 variable and fix them (result of getContent() must be stored in
73 content_t, which is 16-bit)
75 NOTE: Seeds in 1260:6c77e7dbfd29:
77 Spawns you on a small sand island with a surface dungeon
79 Enormous jungle + a surface dungeon at ~(250,0,0)
81 Old, wild and random suggestions that probably won't be done:
82 -------------------------------------------------------------
84 SUGG: If player is on ground, mainly fetch ground-level blocks
86 SUGG: Expose Connection's seqnums and ACKs to server and client.
87 - This enables saving many packets and making a faster connection
88 - This also enables server to check if client has received the
89 most recent block sent, for example.
90 SUGG: Add a sane bandwidth throttling system to Connection
92 SUGG: More fine-grained control of client's dumping of blocks from
94 - ...What does this mean in the first place?
96 SUGG: A map editing mode (similar to dedicated server mode)
98 SUGG: Transfer more blocks in a single packet
99 SUGG: A blockdata combiner class, to which blocks are added and at
100 destruction it sends all the stuff in as few packets as possible.
101 SUGG: Make a PACKET_COMBINED which contains many subpackets. Utilize
102 it by sending more stuff in a single packet.
103 - Add a packet queue to RemoteClient, from which packets will be
104 combined with object data packets
105 - This is not exactly trivial: the object data packets are
106 sometimes very big by themselves
107 - This might not give much network performance gain though.
109 SUGG: Precalculate lighting translation table at runtime (at startup)
110 - This is not doable because it is currently hand-made and not
111 based on some mathematical function.
112 - Note: This has been changing lately
114 SUGG: A version number to blocks, which increments when the block is
115 modified (node add/remove, water update, lighting update)
116 - This can then be used to make sure the most recent version of
117 a block has been sent to client, for example
119 SUGG: Make the amount of blocks sending to client and the total
120 amount of blocks dynamically limited. Transferring blocks is the
121 main network eater of this system, so it is the one that has
122 to be throttled so that RTTs stay low.
124 SUGG: Meshes of blocks could be split into 6 meshes facing into
125 different directions and then only those drawn that need to be
127 SUGG: Background music based on cellular automata?
128 http://www.earslap.com/projectslab/otomata
130 SUGG: Simple light color information to air
132 SUGG: Server-side objects could be moved based on nodes to enable very
133 lightweight operation and simple AI
134 - Not practical; client would still need to show smooth movement.
136 SUGG: Make a system for pregenerating quick information for mapblocks, so
137 that the client can show them as cubes before they are actually sent
140 SUGG: Erosion simulation at map generation time
141 - This might be plausible if larger areas of map were pregenerated
142 without lighting (which is slow)
143 - Simulate water flows, which would carve out dirt fast and
144 then turn stone into gravel and sand and relocate it.
145 - How about relocating minerals, too? Coal and gold in
146 downstream sand and gravel would be kind of cool
147 - This would need a better way of handling minerals, mainly
148 to have mineral content as a separate field. the first
149 parameter field is free for this.
150 - Simulate rock falling from cliffs when water has removed
151 enough solid rock from the bottom
153 SUGG: For non-mapgen FarMesh: Add a per-sector database to store surface
154 stuff as simple flags/values
157 And at some point make the server send this data to the client too,
158 instead of referring to the noise functions
160 - Surface ground type
166 - Aim for something like controlling a single dwarf in Dwarf Fortress
167 - The player could go faster by a crafting a boat, or riding an animal
168 - Random NPC traders. what else?
173 - When furnace is destroyed, move items to player's inventory
176 - Growing grass, decaying leaves
177 - This can be done in the active blocks I guess.
178 - Lots of stuff can be done in the active blocks.
179 - Uh, is there an active block list somewhere? I think not. Add it.
180 - Breaking weak structures
181 - This can probably be accomplished in the same way as grass
182 - Player health points
183 - When player dies, throw items on map (needs better item-on-map
185 - Cobble to get mossy if near water
186 - More slots in furnace source list, so that multiple ingredients
190 - The Treasure Guard; a big monster with a hammer
191 - The hammer does great damage, shakes the ground and removes a block
192 - You can drop on top of it, and have some time to attack there
193 before he shakes you off
195 - Maybe the difficulty could come from monsters getting tougher in
196 far-away places, and the player starting to need something from
197 there when time goes by.
198 - The player would have some of that stuff at the beginning, and
199 would need new supplies of it when it runs out
202 - A spread-items-on-map routine for the bomb, and for dying players
205 - Proper sword swing simulation
206 - Player should get damage from colliding to a wall at high speed
211 Build system / running:
212 -----------------------
214 Networking and serialization:
215 -----------------------------
217 SUGG: Fix address to be ipv6 compatible
225 SUGG: Combine MapBlock's face caches to so big pieces that VBO
227 - That is >500 vertices
228 - This is not easy; all the MapBlocks close to the player would
229 still need to be drawn separately and combining the blocks
230 would have to happen in a background thread
232 SUGG: Make fetching sector's blocks more efficient when rendering
233 sectors that have very large amounts of blocks (on client)
234 - Is this necessary at all?
236 SUGG: Draw cubes in inventory directly with 3D drawing commands, so that
237 animating them is easier.
239 SUGG: Option for enabling proper alpha channel for textures
241 TODO: Flowing water animation
243 TODO: A setting for enabling bilinear filtering for textures
245 TODO: Better control of draw_control.wanted_max_blocks
247 TODO: Further investigate the use of GPU lighting in addition to the
250 TODO: Artificial (night) light could be more yellow colored than sunlight.
251 - This is technically doable.
252 - Also the actual colors of the textures could be made less colorful
253 in the dark but it's a bit more difficult.
255 SUGG: Somehow make the night less colorful
257 TODO: Occlusion culling
258 - At the same time, move some of the renderMap() block choosing code
259 to the same place as where the new culling happens.
260 - Shoot some rays per frame and when ready, make a new list of
261 blocks for usage of renderMap and give it a new pointer to it.
269 TODO: Untie client network operations from framerate
270 - Needs some input queues or something
271 - This won't give much performance boost because calculating block
274 SUGG: Make morning and evening transition more smooth and maybe shorter
276 TODO: Don't update all meshes always on single node changes, but
277 check which ones should be updated
278 - implement Map::updateNodeMeshes() and the usage of it
279 - It will give almost always a 4x boost in mesh update performance.
283 - Tool/weapon visualization
285 FIXME: When disconnected to the menu, memory is not freed properly
287 TODO: Investigate how much the mesh generator thread gets used when
288 transferring map data
293 SUGG: Make an option to the server to disable building and digging near
294 the starting position
296 FIXME: Server sometimes goes into some infinite PeerNotFoundException loop
298 * Fix the problem with the server constantly saving one or a few
299 blocks? List the first saved block, maybe it explains.
300 - It is probably caused by oscillating water
301 - TODO: Investigate if this still happens (this is a very old one)
302 * Make a small history check to transformLiquids to detect and log
303 continuous oscillations, in such detail that they can be fixed.
305 FIXME: The new optimized map sending doesn't sometimes send enough blocks
306 from big caves and such
307 FIXME: Block send distance configuration does not take effect for some reason
312 TODO: Add proper hooks to when adding and removing active blocks
314 TODO: Finish the ActiveBlockModifier stuff and use it for something
319 TODO: Get rid of MapBlockObjects and use only ActiveObjects
320 - Skipping the MapBlockObject data is nasty - there is no "total
321 length" stored; have to make a SkipMBOs function which contains
322 enough of the current code to skip them properly.
324 SUGG: MovingObject::move and Player::move are basically the same.
326 - NOTE: This is a bit tricky because player has the sneaking ability
327 - NOTE: Player::move is more up-to-date.
328 - NOTE: There is a simple move implementation now in collision.{h,cpp}
329 - NOTE: MovingObject will be deleted (MapBlockObject)
331 TODO: Add a long step function to objects that is called with the time
332 difference when block activates
337 TODO: Mineral and ground material properties
338 - This way mineral ground toughness can be calculated with just
339 some formula, as well as tool strengths. Sounds too.
340 - There are TODOs in appropriate files: material.h, content_mapnode.h
342 TODO: Flowing water to actually contain flow direction information
343 - There is a space for this - it just has to be implemented.
345 TODO: Consider smoothening cave floors after generating them
347 TODO: Fix make_tree, make_* to use seed-position-consistent pseudorandom
352 TODO: Make sure server handles removing grass when a block is placed (etc)
353 - The client should not do it by itself
354 - NOTE: I think nobody does it currently...
355 TODO: Block cube placement around player's head
356 TODO: Protocol version field
357 TODO: Think about using same bits for material for fences and doors, for
359 TODO: Move mineral to param2, increment map serialization version, add
362 SUGG: Restart irrlicht completely when coming back to main menu from game.
363 - This gets rid of everything that is stored in irrlicht's caches.
364 - This might be needed for texture pack selection in menu
366 TODO: Merge bahamada's audio stuff (clean patch available)
