17:31 Traxie21_ joined #minetest-mods
17:31 Traxie21_ Does anyone here know how to use file.io very well? Or another way to store persistant data for a time?
17:31 PilzAdam yep
17:32 Traxie21_ Can you give me a quick run-through?
17:32 Traxie21_ I'm not too good with lua :3
17:32 PilzAdam what do you want to save?
17:33 Traxie21_ basicly, [1stname][2ndname][time]
17:33 Traxie21_ but it has to store more than one value of that, and delete it after about 30 seconds
17:33 Traxie21_ I'm making a sorely needed messaging mod
17:34 PilzAdam general reference: http://www.lua.org/pil/21.html
17:34 PilzAdam https://github.com/PilzAdam/b​eds/blob/master/init.lua#L145
17:34 PilzAdam this is from my beds mod
17:34 PilzAdam it saves the beds_player_spawns table in a file
17:35 PilzAdam here is the saving: https://github.com/PilzAdam/b​eds/blob/master/init.lua#L174
17:35 PilzAdam (the first link was reading)
17:35 Traxie21_ I looked at the homes mod, but it didnt make much sense
17:36 PilzAdam you basically do: local file = io.open("file", "w")
17:36 PilzAdam then check for file: if file then
17:36 Traxie21_ ok
17:36 PilzAdam and then write your table into it: file:write(minetest.serialize(your_table))
17:36 PilzAdam file:close()
17:37 Traxie21_ so this right? beds_player_spawns = minetest.deserialize(file:read("*all"))
17:37 PilzAdam and to read it open it with io.open("file", "r")
17:37 PilzAdam and local read_table = minetest.deserialize(file:read("*all"))
17:37 Traxie21_ what line is that in your code?
17:38 PilzAdam line 174 to178 is saving, and 145 to 150 is reading
17:38 Traxie21_ k
17:39 PilzAdam saving more than one table in a file is more complicated
17:39 Traxie21_ hmm
17:39 Traxie21_ dosn't your mod save one bed per player?
17:40 PilzAdam my mod saves the spawn positon indexed by the name
17:40 PilzAdam but the contents of the table are not relevant for saving
17:41 Traxie21_ could you pastebin an example of a file created by beds?
17:41 PilzAdam https://github.com/celeron55/minete​st/blob/master/doc/lua_api.txt#L996
17:41 PilzAdam it looks like this
17:43 PilzAdam files in this format are not well readable by humans
17:43 Traxie21_ Wait, imma install your beds mod and start it up
17:43 PilzAdam you have to sleep one night in the bed
17:44 Traxie21_ k
17:45 Traxie21_ brb
17:47 Traxie21_ how does one get in a bed >_>
17:48 PilzAdam rightclick (requires latest dev version of minetest)
17:48 PilzAdam or use the 0
17:48 PilzAdam .4.4 version
17:48 Traxie21_ I have 0.4.4
17:48 Traxie21_ ooh ok
17:48 PilzAdam (see forum topic)
17:49 Traxie21_ this game is working as hard as possible to make this take as long as possible >.<
17:51 Traxie21_ erm
17:51 Traxie21_ I slept 2 nights in the same bed
17:51 Traxie21_ Where's the file?
17:51 PilzAdam in your worl directory
17:52 PilzAdam *world
17:52 Traxie21_ Ah
17:52 Traxie21_ TYVM
17:52 Traxie21_ ok, it makes a bit more sense now
17:53 PilzAdam here: https://gist.github.com/4540471
17:53 PilzAdam I made some quick helper functions
17:53 PilzAdam (untested)
17:54 PilzAdam it should help you understand the system
17:55 Traxie21_ ok :D
17:55 Traxie21_ I think i got the basics down, just wondering how one would put the param in the second value for write
17:55 Traxie21_ messages_list[player:get_player_name()] = param()
17:55 PilzAdam you can save every table like this
17:55 Traxie21_ im only good with PHP :3
17:56 Traxie21_ Is the syntax for param right?
17:56 PilzAdam Lua tables can more than the arrays of other languages
17:56 PilzAdam depends on what param is
17:57 Traxie21_ wait... how do I pass two params.... God, I know nothing
17:57 PilzAdam what is do you want to save?
17:57 PilzAdam -is
17:57 Traxie21_ playername1, playername 2
17:58 PilzAdam then you can just create a table {playername1, playername2} and save it like this
17:58 PilzAdam s/like this/with the system explained above/
17:59 Traxie21_ I could, but playername2 is a param, and playername 1 is get_player_name()
17:59 PilzAdam can you show me some of your code?
17:59 Traxie21_ I'm trying to do /msg [name] [message]
18:00 Traxie21_ wait... why do I have to save both names....
18:01 PilzAdam like this? http://forum.minetest.net/viewtopic.php?id=2704
18:01 Traxie21_ http://pastebin.com/Rqgh6sHF
18:01 Traxie21_ NUUUU
18:01 Traxie21_ Someone beat me to it >:I
18:01 PilzAdam there are like thousands of version of this command in the forum
18:02 Traxie21_ :I
18:02 Traxie21_ I dont look very far do I
18:02 Traxie21_ is there a /tpa mod?
18:02 PilzAdam what?
18:04 Traxie21_ Teleport requests
18:04 PilzAdam dunno
18:04 Traxie21_ I was working on that, but ran into the file.io problem as well
18:04 PilzAdam you dont have to save things like this in files
18:05 Traxie21_ Is there a way to create persistant variables that can only be used by certian players?
18:05 Traxie21_ Vanessa said she thought file.io was the only way
18:05 PilzAdam VanessaE is wrong
18:05 Traxie21_ Dun dun DUUUUNN
18:06 Traxie21_ ill talk later, I gtg
18:06 Traxie21_ thanks for your help
18:06 PilzAdam np
18:06 Traxie21_ One day I might be able to print hello world
18:06 PilzAdam print("Hello Traxie21_")
18:06 Traxie21_ I know, I was being sarcastic
18:07 Traxie21_ I know very little about Lua syntax
18:07 PilzAdam http://www.lua.org/pil/
18:09 * Traxie21_ will go find some time to read that :3
18:09 Traxie21_ bai
18:09 Traxie21_ thanks again
18:10 VanessaE er, I didn't say file.io was the only way to do what she wants.
18:10 VanessaE I was it was "a" way.
18:11 VanessaE (she? he?  dunno)
18:11 PilzAdam it
18:11 VanessaE heh
19:16 NakedFury joined #minetest-mods
19:37 Traxie21 joined #minetest-mods
19:37 Traxie21 hehe
19:38 Traxie21 Wait
19:38 Traxie21 WOOT
19:38 Traxie21 Plitz, its writing the file properly now :D
19:42 Traxie21 I could use some help figuring out how to read it properly though
19:43 PilzAdam you dont need to write them to a file
19:44 PilzAdam just save them in a varaible you declare outside any function in your script
19:47 Traxie21 static var?
19:47 PilzAdam Lua doesnt have static variables, you can see every variable that isnt declared in a function as "static"
19:48 Traxie21 k
19:48 Traxie21 the issue is, I have to have a variable for each player combination....
19:48 PilzAdam use a 2D table
19:49 PilzAdam {{player1,player2}, {player1, player3}, ...}
19:49 Traxie21 okok, im reading the PIL tutorial... you forced me to it with your fancy terminology XD
19:50 PilzAdam I actually try to use a not Lua specific terminlogy (mixed with Java, C)
19:50 PilzAdam gtg now; bye
19:50 Traxie21 bai
20:02 Traxie21 Is there anyone here who could tell me what I'm doing wrong in a bit of code?
20:09 mauvebic joined #minetest-mods
20:09 Jordach you can continue if you want
20:10 Xenux joined #minetest-mods
20:11 Traxie21 Jordach
20:11 Jordach hm
20:11 Traxie21 Could you help me find a syntax error?
20:11 * Jordach doesnt know lua, but tries to help
20:11 Traxie21 I'm stuck with a simple syntax error...
20:11 Jordach look for the line where it occurs
20:12 Traxie21 luac: prog.lua:23: unexpected symbol near '}'
20:12 Traxie21 http://pastebin.com/Rqgh6sHF
20:12 Traxie21 llooks like a quick fix, but I know almost no lua
20:14 Jordach add a comma to the end of line 20 to look like this: tpr_list[param] = player,
20:15 Jordach lua is an asshole if you dont add commas
20:15 Traxie21 that didnt do it
20:15 Jordach hmm
20:15 Traxie21 Now it says that the comma was unaccepted
20:15 Traxie21 Unexpected symbol near "end" on line 21
20:16 Jordach ehm
20:18 Traxie21 imma try to make the code more readable by not using the same vars for different things XD
20:27 Traxie21 asked for help on forums
