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 NOTE: A random to-do list saved here as documentation:
\r
31 A list of "active blocks" in which stuff happens. (+=done)
\r
32 + Add a never-resetted game timer to the server
\r
33 + Add a timestamp value to blocks
\r
34 + The simple rule: All blocks near some player are "active"
\r
35 - Do stuff in real time in active blocks
\r
37 - Grow grass, delete leaves without a tree
\r
38 - Spawn some mobs based on some rules
\r
39 - Transform cobble to mossy cobble near water
\r
40 - Run a custom script
\r
41 - ...And all kinds of other dynamic stuff
\r
42 + Keep track of when a block becomes active and becomes inactive
\r
43 + When a block goes inactive:
\r
44 + Store objects statically to block
\r
45 + Store timer value as the timestamp
\r
46 + When a block goes active:
\r
47 + Create active objects out of static objects
\r
48 - Simulate the results of what would have happened if it would have
\r
49 been active for all the time
\r
50 - Grow a lot of grass and so on
\r
51 + Initially it is fine to send information about every active object
\r
52 to every player. Eventually it should be modified to only send info
\r
53 about the nearest ones.
\r
54 + This was left to be done by the old system and it sends only the
\r
57 Old, wild and random suggestions that probably won't be done:
\r
58 -------------------------------------------------------------
\r
60 SUGG: If player is on ground, mainly fetch ground-level blocks
\r
62 SUGG: Expose Connection's seqnums and ACKs to server and client.
\r
63 - This enables saving many packets and making a faster connection
\r
64 - This also enables server to check if client has received the
\r
65 most recent block sent, for example.
\r
66 SUGG: Add a sane bandwidth throttling system to Connection
\r
68 SUGG: More fine-grained control of client's dumping of blocks from
\r
70 - ...What does this mean in the first place?
\r
72 SUGG: A map editing mode (similar to dedicated server mode)
\r
74 SUGG: Transfer more blocks in a single packet
\r
75 SUGG: A blockdata combiner class, to which blocks are added and at
\r
76 destruction it sends all the stuff in as few packets as possible.
\r
77 SUGG: Make a PACKET_COMBINED which contains many subpackets. Utilize
\r
78 it by sending more stuff in a single packet.
\r
79 - Add a packet queue to RemoteClient, from which packets will be
\r
80 combined with object data packets
\r
81 - This is not exactly trivial: the object data packets are
\r
82 sometimes very big by themselves
\r
83 - This might not give much network performance gain though.
\r
85 SUGG: Precalculate lighting translation table at runtime (at startup)
\r
86 - This is not doable because it is currently hand-made and not
\r
87 based on some mathematical function.
\r
88 - Note: This has been changing lately
\r
90 SUGG: A version number to blocks, which increments when the block is
\r
91 modified (node add/remove, water update, lighting update)
\r
92 - This can then be used to make sure the most recent version of
\r
93 a block has been sent to client, for example
\r
95 SUGG: Make the amount of blocks sending to client and the total
\r
96 amount of blocks dynamically limited. Transferring blocks is the
\r
97 main network eater of this system, so it is the one that has
\r
98 to be throttled so that RTTs stay low.
\r
100 SUGG: Meshes of blocks could be split into 6 meshes facing into
\r
101 different directions and then only those drawn that need to be
\r
103 SUGG: Background music based on cellular automata?
\r
104 http://www.earslap.com/projectslab/otomata
\r
106 SUGG: Simple light color information to air
\r
108 SUGG: Server-side objects could be moved based on nodes to enable very
\r
109 lightweight operation and simple AI
\r
110 - Not practical; client would still need to show smooth movement.
\r
112 SUGG: Make a system for pregenerating quick information for mapblocks, so
\r
113 that the client can show them as cubes before they are actually sent
\r
116 SUGG: Erosion simulation at map generation time
\r
117 - This might be plausible if larger areas of map were pregenerated
\r
118 without lighting (which is slow)
\r
119 - Simulate water flows, which would carve out dirt fast and
\r
120 then turn stone into gravel and sand and relocate it.
\r
121 - How about relocating minerals, too? Coal and gold in
\r
122 downstream sand and gravel would be kind of cool
\r
123 - This would need a better way of handling minerals, mainly
\r
124 to have mineral content as a separate field. the first
\r
125 parameter field is free for this.
\r
126 - Simulate rock falling from cliffs when water has removed
\r
127 enough solid rock from the bottom
\r
132 - Aim for something like controlling a single dwarf in Dwarf Fortress
\r
133 - The player could go faster by a crafting a boat, or riding an animal
\r
134 - Random NPC traders. what else?
\r
139 - When furnace is destroyed, move items to player's inventory
\r
140 - Add lots of stuff
\r
142 - Growing grass, decaying leaves
\r
143 - This can be done in the active blocks I guess.
\r
144 - Lots of stuff can be done in the active blocks.
\r
145 - Uh, is there an active block list somewhere? I think not. Add it.
\r
146 - Breaking weak structures
\r
147 - This can probably be accomplished in the same way as grass
\r
148 - Player health points
\r
149 - When player dies, throw items on map (needs better item-on-map
\r
151 - Cobble to get mossy if near water
\r
152 - More slots in furnace source list, so that multiple ingredients
\r
156 - The Treasure Guard; a big monster with a hammer
\r
157 - The hammer does great damage, shakes the ground and removes a block
\r
158 - You can drop on top of it, and have some time to attack there
\r
159 before he shakes you off
\r
161 - Maybe the difficulty could come from monsters getting tougher in
\r
162 far-away places, and the player starting to need something from
\r
163 there when time goes by.
\r
164 - The player would have some of that stuff at the beginning, and
\r
165 would need new supplies of it when it runs out
\r
168 - A spread-items-on-map routine for the bomb, and for dying players
\r
171 - Proper sword swing simulation
\r
172 - Player should get damage from colliding to a wall at high speed
\r
177 Build system / running:
\r
178 -----------------------
\r
180 Networking and serialization:
\r
181 -----------------------------
\r
183 SUGG: Fix address to be ipv6 compatible
\r
191 SUGG: Combine MapBlock's face caches to so big pieces that VBO
\r
193 - That is >500 vertices
\r
194 - This is not easy; all the MapBlocks close to the player would
\r
195 still need to be drawn separately and combining the blocks
\r
196 would have to happen in a background thread
\r
198 SUGG: Make fetching sector's blocks more efficient when rendering
\r
199 sectors that have very large amounts of blocks (on client)
\r
200 - Is this necessary at all?
\r
202 TODO: Flowing water animation
\r
204 SUGG: Draw cubes in inventory directly with 3D drawing commands, so that
\r
205 animating them is easier.
\r
207 SUGG: Option for enabling proper alpha channel for textures
\r
208 TODO: A setting for enabling bilinear filtering for textures
\r
210 TODO: Better control of draw_control.wanted_max_blocks
\r
212 TODO: Further investigate the use of GPU lighting in addition to the
\r
215 TODO: Artificial (night) light could be more yellow colored than sunlight.
\r
216 - This is technically doable.
\r
217 - Also the actual colors of the textures could be made less colorful
\r
218 in the dark but it's a bit more difficult.
\r
220 SUGG: Somehow make the night less colorful
\r
228 TODO: Untie client network operations from framerate
\r
229 - Needs some input queues or something
\r
230 - This won't give much performance boost because calculating block
\r
231 meshes takes so long
\r
233 SUGG: Make morning and evening transition more smooth and maybe shorter
\r
235 TODO: Don't update all meshes always on single node changes, but
\r
236 check which ones should be updated
\r
237 - implement Map::updateNodeMeshes() and the usage of it
\r
238 - It will give almost always a 4x boost in mesh update performance.
\r
242 - Tool/weapon visualization
\r
244 FIXME: When disconnected to the menu, memory is not freed properly
\r
246 TODO: Investigate how much the mesh generator thread gets used when
\r
247 transferring map data
\r
252 SUGG: Make an option to the server to disable building and digging near
\r
253 the starting position
\r
255 FIXME: Server sometimes goes into some infinite PeerNotFoundException loop
\r
257 * Fix the problem with the server constantly saving one or a few
\r
258 blocks? List the first saved block, maybe it explains.
\r
259 - It is probably caused by oscillating water
\r
260 - TODO: Investigate if this still happens (this is a very old one)
\r
261 * Make a small history check to transformLiquids to detect and log
\r
262 continuous oscillations, in such detail that they can be fixed.
\r
264 FIXME: The new optimized map sending doesn't sometimes send enough blocks
\r
265 from big caves and such
\r
266 FIXME: Block send distance configuration does not take effect for some reason
\r
271 TODO: Add proper hooks to when adding and removing active blocks
\r
273 TODO: Finish the ActiveBlockModifier stuff and use it for something
\r
278 TODO: Get rid of MapBlockObjects and use only ActiveObjects
\r
279 - Skipping the MapBlockObject data is nasty - there is no "total
\r
280 length" stored; have to make a SkipMBOs function which contains
\r
281 enough of the current code to skip them properly.
\r
283 SUGG: MovingObject::move and Player::move are basically the same.
\r
285 - NOTE: This is a bit tricky because player has the sneaking ability
\r
286 - NOTE: Player::move is more up-to-date.
\r
287 - NOTE: There is a simple move implementation now in collision.{h,cpp}
\r
288 - NOTE: MovingObject will be deleted (MapBlockObject)
\r
290 TODO: Add a long step function to objects that is called with the time
\r
291 difference when block activates
\r
296 TODO: Mineral and ground material properties
\r
297 - This way mineral ground toughness can be calculated with just
\r
298 some formula, as well as tool strengths
\r
299 - There are TODOs in appropriate files: material.h, content_mapnode.h
\r
301 TODO: Flowing water to actually contain flow direction information
\r
302 - There is a space for this - it just has to be implemented.
\r
306 TODO: Make sure server handles removing grass when a block is placed (etc)
\r
307 - The client should not do it by itself
\r
308 - NOTE: I think nobody does it currently...
\r
309 TODO: Block cube placement around player's head
\r
310 TODO: Protocol version field
\r
311 TODO: Think about using same bits for material for fences and doors, for
\r
313 TODO: Move mineral to param2, increment map serialization version, add
\r
316 TODO: Add a per-sector database to store surface stuff as simple flags/values
\r
319 And at some point make the server send this data to the client too,
\r
320 instead of referring to the noise functions
\r
322 - Surface ground type
\r
325 TODO: Restart irrlicht completely when coming back to main menu from game.
\r
326 - This gets rid of everything that is stored in irrlicht's caches.
\r
328 TODO: Merge bahamada's audio stuff (clean patch available)
\r
330 TODO: Merge key configuration menu (no clean patch available)
\r
332 Making it more portable:
\r
333 ------------------------
\r
335 Stuff to do before release:
\r
336 ---------------------------
\r
338 Fixes to the current release:
\r

\r
341 Stuff to do after release:
