10:22 jin_xi Taoki: if i want to test your code, what do i do? just try to hold a pick?
10:23 Taoki jin_xi: No, not there yet
10:23 jin_xi ok, so far i have started a server an two clients to see the meshes
10:23 Taoki jin_xi: There's only a test script which, 10 seconds after the server starts, it detects a player with the given playername (replace it with yours) and attaches to it
10:23 jin_xi ah, ok
10:23 Taoki Yes, that parts work. It's the attachments that are a problem
10:24 Taoki The lua entity has the same mesh so it might be harder to find
10:25 Taoki The issue is that currently, it crashes when I attach. Because I'm trying to get the parent mesh but for some reason it gets a null mesh instead
10:25 jin_xi yes. i just try to reproduce this crash here
10:25 Taoki jin_xi: In my code, uncomment the line v3f test = parent_mesh->getPosition(); This is what will cause a segmentation fault in the client at the moment of attachment
10:25 Taoki Because parent_mesh is returned null, although it should be the other object's
10:26 jin_xi ok. that script you mentioned, where is it?
10:27 Taoki In my game branch from GIT, for minetest_game
10:27 Taoki The file is player.lua
10:28 jin_xi k thanks
10:28 jin_xi how do you test? singleplayer?
10:30 Taoki jin_xi: Yes, but I recommend running minetestserver separately in a console, then connecting a client to 127.0.0.1. Also, you'll have to re-make the world each time, because the LUA entity currently breaks it after the server shuts down (unless you punch it in-world to remove it). So don't test with a world you wish to keep
10:31 Taoki jin_xi: But currently, in player.lua, change "MirceaKitsune" with your player name. Then start the server, log in under 10 seconds with the client, then wait for the lua entity to be spawned and attached to you. That line I mentioned will currently cause a segmentation fault
10:31 jin_xi ok  thanks will get testin'
10:31 Taoki Because parent_mesh is for some reason null, although m_attachment_parent (the ClientActiveObject) is the proper one
10:31 Taoki ok. And thanks for the help, very appreciated :)
10:34 jin_xi i'm really happy to see somebody tackling this problem and admire how far you've come!
10:37 Taoki Thanks! I'm glad, since this is first of all my first considerable contribution to MineTest, or anything wrotten in C++ up to this day. I'm glad I managed to understand the code enough to get this far
10:37 Taoki But, at some point, I do get pretty stuck. Like here
10:37 Taoki After attachments are over there's some smaller issues to be fixed, but those are the biggest problem now, and still quite a bit to do left
10:38 Taoki Once the code is ready I also think I'll try to make an animated player model and implement part of it in lua too, but first the code needs to be done
10:39 jin_xi mhh, so i have to join my server in under 10 secs after i start it?
10:39 jin_xi otherwise it'll be gone already?
10:45 Taoki yeah
10:45 Taoki Since the script triggers the attachment 10 seconds after the server starts
10:45 Taoki Didn't make a better script yet, I'm not goog with lua either... just something to test this
10:46 jin_xi ah, there. was missing your last commit to game ;)
10:48 jin_xi ERROR[ServerThread]: LuaEntity name "test:test2" not defined Attached test object to MirceaKitsune (sorry im using your nick)
10:48 jin_xi will change to jin_xi now :)
10:53 Taoki jin_xi: That's ok. And yes, that warning is unrelated. Likely something I'm missing about the lua script
10:54 jin_xi ok, am looking at it atm
10:56 OdnetninI joined #minetest-delta
10:57 OdnetninI I've download lastest github code and minetestserver doesn't compile:
10:57 OdnetninI Linking CXX executable ../bin/minetestserver CMakeFiles/minetestserver.dir/rollback.cpp.o: file not recognized: File truncated colle
11:13 jin_xi Taoki: http://pastebin.com/3NRDefc0 this adds the proper entity and should thus eliminate the step with creating a new world for every test
11:13 Taoki OdnetninI: No idea about that. I updated the GIT several days ago and it works fine, can't check if an update since then broke it
11:14 jin_xi ^ it says truncated, try cloning again?
11:14 Taoki jin_xi: Thank you, I will update my test script on GIT as well so others don't have the same issue. That part is due to me not knowing lua well enough for fixing it
11:14 Taoki But the null mesh crash is unrelated so yeah
11:14 jin_xi i know
11:16 OdnetninI i've download again, and i'm trying to recompile
11:22 OdnetninI solved, it was a download problem, thanks.
11:29 Taoki jin_xi: Are you able to reproduce the crash I have (segmentation fault on the client side when the entity is attached)? Can you confirm it's because in the code parent_mesh is for some reason null?
11:30 jin_xi yes i have this crash. but im not running in gdb or so
11:30 jin_xi but yes, server keeps going, client times out
11:30 Taoki ok. Don't think gsb is needed much since I already tried that and know it's because parent_mesh is null. The reason for that is unknown though
11:32 Taoki Ahhhhh! I'm not sure about this, but I think I might just have an idea as to why it happens, all of a sudden popping up in my head :P
11:32 Taoki Maybe it's because your own player model is hidden locally. You don't see yourself, only others see you as a visual mesh. So if the client tries to get the mesh for your own player, it fails, cuz you're invisible to yourself
11:33 Taoki What we then need in order to be sure is to skil drawing or handling attachments when the parent is your own self. Which in the end will be the intended behavior
11:34 PilzAdam Taoki, would it be possible to make your own model visible? so if you look down you see your feet
11:35 Taoki PilzAdam: That would be a different feature to be done later on. It would be really nice however, but a distant feature
11:35 PilzAdam I know its a different feature
11:35 Taoki You'd need a bone on the mesh as well to position the head, and the risk of the view poking into your mesh would be big
11:36 Taoki Technically, it should be. But it will take quite some work to do if it will be attempted
11:39 Taoki jin_xi: Ok, I need to find out how to know if m_attachment_parent is the same as the local playe client-side, in content_cao.cpp. So I can isolate the case where the object attempts to be attached to the player which sees himself as invisible (and therefore there's no mesh)
11:39 Steve_the_ripper joined #minetest-delta
11:39 Taoki Maybe that's the only case of a null mesh
11:40 Taoki hi
11:40 Taoki ah-hah... it's called LocalPlayer or player
12:18 Taoki jin_xi: Seems I got it working at last :) The issue was indeed tetting the mesh of the local player, which was NULL since he's hidden to himself
12:19 jin_xi huh
12:19 Taoki joined #minetest-delta
12:20 jin_xi cool
12:27 Taoki jin_xi: I fixed the crash, please pull my latest code
12:27 jin_xi sec
12:27 Taoki jin_xi: It was indeed because the local player has no mesh to himself, so you can't attach to him. Now I need to remove the cleint-side attachment overall for local players
12:27 Taoki ok
12:31 jin_xi yes, looking good
12:31 jin_xi brb
12:34 Taoki ok. Need to fully correct that change though, working on that now. Then see how Irrlicht will handle attaching
