21 =============================== NOTES ==============================
\r
22 NOTE: Things starting with TODO are sometimes only suggestions.
\r
24 NOTE: iostream.imbue(std::locale("C")) is very slow
\r
25 NOTE: Global locale is now set at initialization
\r
27 NOTE: If VBO (EHM_STATIC) is used, remember to explicitly free the
\r
28 hardware buffer (it is not freed automatically)
\r
30 Old, wild and random suggestions that probably won't be done:
\r
31 -------------------------------------------------------------
\r
33 SUGG: If player is on ground, mainly fetch ground-level blocks
\r
35 SUGG: Expose Connection's seqnums and ACKs to server and client.
\r
36 - This enables saving many packets and making a faster connection
\r
37 - This also enables server to check if client has received the
\r
38 most recent block sent, for example.
\r
39 SUGG: Add a sane bandwidth throttling system to Connection
\r
41 SUGG: More fine-grained control of client's dumping of blocks from
\r
43 - ...What does this mean in the first place?
\r
45 SUGG: A map editing mode (similar to dedicated server mode)
\r
47 SUGG: Transfer more blocks in a single packet
\r
48 SUGG: A blockdata combiner class, to which blocks are added and at
\r
49 destruction it sends all the stuff in as few packets as possible.
\r
50 SUGG: Make a PACKET_COMBINED which contains many subpackets. Utilize
\r
51 it by sending more stuff in a single packet.
\r
52 - Add a packet queue to RemoteClient, from which packets will be
\r
53 combined with object data packets
\r
54 - This is not exactly trivial: the object data packets are
\r
55 sometimes very big by themselves
\r
56 - This might not give much network performance gain though.
\r
58 SUGG: Precalculate lighting translation table at runtime (at startup)
\r
59 - This is not doable because it is currently hand-made and not
\r
60 based on some mathematical function.
\r
61 - Note: This has been changing lately
\r
63 SUGG: A version number to blocks, which increments when the block is
\r
64 modified (node add/remove, water update, lighting update)
\r
65 - This can then be used to make sure the most recent version of
\r
66 a block has been sent to client, for example
\r
68 SUGG: Make the amount of blocks sending to client and the total
\r
69 amount of blocks dynamically limited. Transferring blocks is the
\r
70 main network eater of this system, so it is the one that has
\r
71 to be throttled so that RTTs stay low.
\r
73 SUGG: Meshes of blocks could be split into 6 meshes facing into
\r
74 different directions and then only those drawn that need to be
\r
76 SUGG: Calculate lighting per vertex to get a lighting effect like in
\r
79 SUGG: Background music based on cellular automata?
\r
80 http://www.earslap.com/projectslab/otomata
\r
82 SUGG: Simple light color information to air
\r
84 SUGG: Server-side objects could be moved based on nodes to enable very
\r
85 lightweight operation and simple AI
\r
86 - Not practical; client would still need to show smooth movement.
\r
91 - Aim for something like controlling a single dwarf in Dwarf Fortress
\r
92 - The player could go faster by a crafting a boat, or riding an animal
\r
93 - Random NPC traders. what else?
\r
98 - When furnace is destroyed, move items to player's inventory
\r
101 - Growing grass, decaying leaves
\r
102 - This can be done in the active blocks I guess.
\r
103 - Lots of stuff can be done in the active blocks.
\r
104 - Uh, is there an active block list somewhere? I think not. Add it.
\r
105 - Breaking weak structures
\r
106 - This can probably be accomplished in the same way as grass
\r
107 - Player health points
\r
108 - When player dies, throw items on map (needs better item-on-map
\r
110 - Cobble to get mossy if near water
\r
111 - More slots in furnace source list, so that multiple ingredients
\r
115 - The Treasure Guard; a big monster with a hammer
\r
116 - The hammer does great damage, shakes the ground and removes a block
\r
117 - You can drop on top of it, and have some time to attack there
\r
118 before he shakes you off
\r
120 - Maybe the difficulty could come from monsters getting tougher in
\r
121 far-away places, and the player starting to need something from
\r
122 there when time goes by.
\r
123 - The player would have some of that stuff at the beginning, and
\r
124 would need new supplies of it when it runs out
\r
127 - A spread-items-on-map routine for the bomb, and for dying players
\r
130 - Proper sword swing simulation
\r
131 - Player should get damage from colliding to a wall at high speed
\r
136 Build system / running:
\r
137 -----------------------
\r
139 Networking and serialization:
\r
140 -----------------------------
\r
142 SUGG: Fix address to be ipv6 compatible
\r
150 SUGG: Combine MapBlock's face caches to so big pieces that VBO
\r
152 - That is >500 vertices
\r
153 - This is not easy; all the MapBlocks close to the player would
\r
154 still need to be drawn separately and combining the blocks
\r
155 would have to happen in a background thread
\r
157 SUGG: Make fetching sector's blocks more efficient when rendering
\r
158 sectors that have very large amounts of blocks (on client)
\r
159 - Is this necessary at all?
\r
161 TODO: Flowing water animation
\r
163 SUGG: Draw cubes in inventory directly with 3D drawing commands, so that
\r
164 animating them is easier.
\r
166 SUGG: Option for enabling proper alpha channel for textures
\r
167 TODO: A setting for enabling bilinear filtering for textures
\r
169 TODO: Better control of draw_control.wanted_max_blocks
\r
171 TODO: Block mesh generator to tile properly on smooth lighting
\r
179 TODO: Untie client network operations from framerate
\r
180 - Needs some input queues or something
\r
181 - This won't give much performance boost because calculating block
\r
182 meshes takes so long
\r
184 SUGG: Make morning and evening transition more smooth and maybe shorter
\r
186 TODO: Don't update all meshes always on single node changes, but
\r
187 check which ones should be updated
\r
188 - implement Map::updateNodeMeshes() and the usage of it
\r
189 - It will give almost always a 4x boost in mesh update performance.
\r
193 - Tool/weapon visualization
\r
195 FIXME: When disconnected to the menu, memory is not freed properly
\r
200 SUGG: Make an option to the server to disable building and digging near
\r
201 the starting position
\r
203 FIXME: Server sometimes goes into some infinite PeerNotFoundException loop
\r
205 * Fix the problem with the server constantly saving one or a few
\r
206 blocks? List the first saved block, maybe it explains.
\r
207 - It is probably caused by oscillating water
\r
208 * Make a small history check to transformLiquids to detect and log
\r
209 continuous oscillations, in such detail that they can be fixed.
\r
211 FIXME: The new optimized map sending doesn't sometimes send enough blocks
\r
212 from big caves and such
\r
214 TODO: A list of "active blocks" in which stuff happens.
\r
215 + Add a never-resetted game timer to the server
\r
216 + Add a timestamp value to blocks
\r
217 + The simple rule: All blocks near some player are "active"
\r
218 - Do stuff in real time in active blocks
\r
220 TODO: Make proper hooks in here
\r
221 - Grow grass, delete leaves without a tree
\r
222 - Spawn some mobs based on some rules
\r
223 - Transform cobble to mossy cobble near water
\r
224 - Run a custom script
\r
225 - ...And all kinds of other dynamic stuff
\r
226 + Keep track of when a block becomes active and becomes inactive
\r
227 + When a block goes inactive:
\r
228 + Store objects statically to block
\r
229 + Store timer value as the timestamp
\r
230 + When a block goes active:
\r
231 + Create active objects out of static objects
\r
232 TODO: Make proper hooks in here
\r
233 - Simulate the results of what would have happened if it would have
\r
234 been active for all the time
\r
235 - Grow a lot of grass and so on
\r
236 + Initially it is fine to send information about every active object
\r
237 to every player. Eventually it should be modified to only send info
\r
238 about the nearest ones.
\r
239 + This was left to be done by the old system and it sends only the
\r
245 TODO: Get rid of MapBlockObjects and use only ActiveObjects
\r
246 - Skipping the MapBlockObject data is nasty - there is no "total
\r
247 length" stored; have to make a SkipMBOs function which contains
\r
248 enough of the current code to skip them properly.
\r
250 SUGG: MovingObject::move and Player::move are basically the same.
\r
252 - NOTE: Player::move is more up-to-date.
\r
253 - NOTE: There is a simple move implementation now in collision.{h,cpp}
\r
254 - NOTE: MovingObject will be deleted (MapBlockObject)
\r
259 TODO: Mineral and ground material properties
\r
260 - This way mineral ground toughness can be calculated with just
\r
261 some formula, as well as tool strengths
\r
263 TODO: Flowing water to actually contain flow direction information
\r
264 - There is a space for this - it just has to be implemented.
\r
266 SUGG: Erosion simulation at map generation time
\r
267 - Simulate water flows, which would carve out dirt fast and
\r
268 then turn stone into gravel and sand and relocate it.
\r
269 - How about relocating minerals, too? Coal and gold in
\r
270 downstream sand and gravel would be kind of cool
\r
271 - This would need a better way of handling minerals, mainly
\r
272 to have mineral content as a separate field. the first
\r
273 parameter field is free for this.
\r
274 - Simulate rock falling from cliffs when water has removed
\r
275 enough solid rock from the bottom
\r
277 SUGG: Try out the notch way of generating maps, that is, make bunches
\r
278 of low-res 3d noise and interpolate linearly.
\r
281 * Possibly add some kind of erosion and other stuff
\r
282 * Better water generation (spread it to underwater caverns but don't
\r
283 fill dungeons that don't touch big water masses)
\r
284 * When generating a chunk and the neighboring chunk doesn't have mud
\r
285 and stuff yet and the ground is fairly flat, the mud will flow to
\r
286 the other chunk making nasty straight walls when the other chunk
\r
287 is generated. Fix it. Maybe just a special case if the ground is
\r
292 * Make an "environment metafile" to store at least time of day
\r
293 * Move digging property stuff from material.{h,cpp} to mapnode.cpp...
\r
294 - Or maybe move content_features to material.{h,cpp}?
\r
296 Make a system for pregenerating quick information for mapblocks, so
\r
297 that the client can show them as cubes before they are actually sent
\r
300 Making it more portable:
\r
301 ------------------------
\r
302 * Some MSVC: std::sto* are defined without a namespace and collide
\r
303 with the ones in utility.h
