11:32 Nemin32     Hi!
11:33 Nemin32     Is there a command for running an abm once?
11:34 Nemin32     Like i have a block and i want it to put another block on top of it, but only once.
11:35 Nemin32     And if i punch that block out on top thats it.
11:41 Nemin32     I tried making a local var. that turns false when the first spawning happened, but it didnt worked.
11:47 Zefram_Fysh you need to implement your own concept of "once"
11:48 Zefram_Fysh there is no API mechanism to do it for you
12:26 Nemin32     Hmm
12:26 Nemin32     Well, this is sad
12:28 Nemin32     Then can you please comment on my code what is the problem with it: http://pastebin.com/TG6sHTFS  ?
14:53 LazyJ       Nemin32, I haven't read the pastebin but something that may work (and is much more complex) would be to have the node on top replace the node on bottom "on_punch" or "after_punch" with a node of a *different* name but same texture and definition as the original, bottom node.
14:54 LazyJ       That way the ABM only works on the original bottom node but not the near identical node of a different name (i.e. bottom_node vs bottom_node_2).
15:40 Nemin32     Wow, i would never thought that thank you!
15:41 LazyJ       yw, I hope it works. ;)
15:46 Nemin32     You know, my friend is a big fan of an anime, where the protagonist has a dimension named the unlimited blade works, where he has every type of swords and stuff, and i wanted to make him a block which spawns a 25*25 area of blocks that spawn "sword-blocks" on top.
15:48 LazyJ       It would be a neat effect to pull-off.
15:48 LazyJ       What you learn by doing it may help in the future with a similar problem. ;)
15:49 Nemin32     :)
15:52 Nemin32     Great, it works nearly as i wanted!
15:57 Nemin32     Oh, my! It look good.
15:57 Nemin32     My friend will be happy, i think.
16:37 Nemin32     And can i ask you one more thing? Is it possible to orientate my spawning blocks like if i place my block from standing north my square will spawn north etc. etc.
16:37 Nemin32     ?
16:43 Nemin32     WTF, i cant delete my block using minetest.remove_node!
16:45 LazyJ       To remove the node, try minetest.set_node("air")
16:45 Nemin32     Yep, i tried that.
16:45 LazyJ       The orientated deployment of blocks is something I haven't messed with yet.
16:45 Nemin32     Well then nevermind that
16:46 Nemin32     But the no-remove thing is a problem
16:46 LazyJ       Is something putting the block back after it is removed? That is another possibility.
16:47 Nemin32     Hmm
16:47 LazyJ       When I come to problems like that, I try to isolate just that block in it's own special "test" mod.
16:48 Nemin32     Well, this is a test mod too.
16:48 LazyJ       Comment-out all the stuff that works and is not necessary and focus on just that one problem.
16:48 Nemin32     Just goofing around getting the basics.
16:49 LazyJ       Sometimes the problems I've had were the right code in the wrong place or sequence of events.
16:50 LazyJ       As for deploying nodes based on the player's orientation, I'd look into thefamilygrog66's "Living Room Furniture" mod, the long sofas.
16:51 LazyJ       Another one would be mauvebic's "Ruler" mod.
16:51 Nemin32     Hmm, now its deleting, it seems the problem is in the square generating code
16:51 Nemin32     Ok thanks
16:51 LazyJ       Possibly even Sokomine's "Villages" mod.
17:04 Nemin32     Hmm, after some experimenting the blocks vanishes for a moment, howewer it reappears right after
17:05 LazyJ       Then something in the code is putting it back.
17:06 LazyJ       Use WorldEdit's   /i on    to "tap" the node that returns. It will display in chat the modname:nodename of that node. That will give you an idea of what to look for.
17:07 LazyJ       Especially if you are using doppelganger nodes.
17:07 Nemin32     Umm, i know its name
17:07 Nemin32     The worst that its actually never referenced after the destroy command.
17:08 LazyJ       Something before the destroy command may be the issue.
17:08 LazyJ       If you are using something to replace the node when the one above it is punched, that replacement code may still be working or the ABM may still be putting it there.
17:09 LazyJ       Work your way backwards.
17:10 Nemin32     Hmm, well the spawner block is not affected by the replacement code
17:11 Nemin32     Would you please see my code?
17:13 LazyJ       I can take a look, but no promises. I'm struggling with Lua and mods myself. ;)
17:13 LazyJ       What's the current version's pastebin?
17:15 Nemin32     http://pastebin.com/pmrkmamx
17:15 Nemin32     This is the ABM of the spawner
17:17 LazyJ       Just a guess but:
17:17 LazyJ       minetest.remove_node(savedpos)
17:17 Nemin32     Its there
17:17 LazyJ       looks like it's telling Minetest to remove a *position* but not *what* to remove.
17:17 Nemin32     Oh
17:18 LazyJ       You are trying to do the opposite of:
17:18 LazyJ       minetest.set_node(pos, {name = "ubw:dirt_active"})
17:18 LazyJ       Which specifies the position and the item.
17:18 Nemin32     Well, then how could i fix itm
17:18 Nemin32     ?
17:18 LazyJ       So try doing that with the remove verion; specify the pos *and* the item.
17:20 Nemin32     so i put minetest.remove_node(savedpos, {name = "ubw:spawner}) but nothing
17:21 LazyJ       Say the process out loud sometimes helps. "Minetest, 'remove_node' in this 'pos' if it's 'name' is '{name=ubw:spawner}'."
17:21 Nemin32     the documentation says i only need a position
17:22 LazyJ       You have 'pos' identified as 'savedpos'. What describes 'savedpos'?
17:22 Nemin32     in function(pos) savedpos = pos
17:23 LazyJ       You have it turned around.
17:23 Nemin32     why?
17:23 LazyJ       It should be 'pos = savedpos'.
17:23 Nemin32     I am declaring savedpos, it should be the beginning position, so i can do my thing with pos.
17:24 Nemin32     but i will try
17:24 LazyJ       function(pos, name, item_stack) etc... is already taken by the builtin mod.
17:25 LazyJ       That's what allows you to do things like 'minetest.get_node(pos).name'
17:25 LazyJ       'pos'
17:25 LazyJ       Ahk...
17:25 Nemin32     So i cant modify it
17:25 LazyJ       'pos' is already claimed by another function.
17:25 LazyJ       idk.
17:25 Nemin32     *facepalm
17:25 LazyJ       Give it a try and see what happens.
17:26 Nemin32     Soo if i put pos into another var, and i place the thing to the another var it will work?
17:27 LazyJ       It may work but will it conflict with other functions calling for 'pos'?
17:28 LazyJ       If you were to use 'local cobble = minetest.get_node(pos)', then 'minetest.register_node(default:cobble)' may have an issue.
17:28 Nemin32     I have another function who edits pos
17:29 LazyJ       That example is just to illustrate.
17:29 LazyJ       Other than that, I'm out of ideas. :(
17:30 Nemin32     if i write function(local pos)?
17:31 Nemin32     Or put it into another file and dofile()?
17:31 LazyJ       I haven't written my own functions yet to understand them well enough.
17:32 LazyJ       So I stick with what other's have written.
17:32 Nemin32     Ok, local does not work, i try the dofile()
17:32 LazyJ       Looking at some of the older mods, *everything* was done in a single init.lua file.
17:33 LazyJ       Crafts, registrations, ABMs... the whole ball of wax.
17:33 LazyJ       So if they could do it all in one file, then you should be able to get yours to work in a single file too.
17:34 Nemin32     But it worth one try.
17:34 LazyJ       Unless the rest of your mod is huge, in which case it's easier to keep your sanity if you break it into smaller files.
17:36 Nemin32     No its small (for now)
17:53 Nemin32     OK, so i have two variations: one) It works, howewer only for the first, then every other just dissapears two) like before modifiyng.
18:02 LazyJ       Try allowing only 3 to spawn. If it is consistently evens or consistently odds that disappears, then the likely suspect is the position(s) used in the code.
18:03 LazyJ       If it's consistently random, then look for other things that tell Minetest to either remove, replace, or expire something.
18:06 LazyJ       "Simplify. Identify. Retry."
18:06 Nemin32     Is there a function to check if a node *removed* not *dug*
18:07 LazyJ       I've never had an instance to look for one yet.
18:07 LazyJ       By default, whenever something is "dug", Minetest records it in the logs. Key into that perhaps?
18:08 LazyJ       If it's not dug, then assume it was removed.
18:09 Nemin32     Hmm, well i must go, a sleep may help :) Anyway thank you very much for your help! And bye!
18:09 LazyJ       Good luck  ;)
