I kept getting server crashes with the new adv_spawning/internal.lua:294 assertian failed

disabled that part of the mod and everything else seems to work fine

by **sapier** » Mon Jul 21, 2014 15:54

could you provide a backtrace for one of those crashes? There's no reason why something should be done in negative time so there most likely is a bug hidden somewhere else.
Thanks!

I tried the latest github and still get timeout errors for spawning mobs...

by **fifthecard** » Mon Jul 21, 2014 22:16

Don't really know how to do a backtrace other than using gdb. Here is what I have. Let me know if this helped. I am using Manjaro / Arch linux.

Code: Select all: gdb) bt full #0 0x00007ffff645cd67 in raise () from /usr/lib/libc.so.6 No symbol table info available. #1 0x00007ffff645e118 in abort () from /usr/lib/libc.so.6 No symbol table info available. #2 0x0000000000590f54 in assert_fail(char const*, char const*, unsigned int, char const*) () No symbol table info available. #3 0x00000000004541a0 in main () No symbol table info available. (gdb)

@TenPlus1 can you please post the full error message?
@fifthecard while usually a gdb backtrace helps, in this situation I'd need the lua backtrace ... it's shown on console and saved in debug.txt

by **fifthecard** » Wed Jul 23, 2014 18:06

Here is the debug info

Code: Select all: 6:51:44: ERROR[main]: ERROR: An unhandled exception occurred: ....minetest/mods/animals_modpack/adv_spawning/internal.lua:294: assertion failed! 16:51:44: ERROR[main]: stack traceback: 16:51:44: ERROR[main]: [C]: in function 'assert' 16:51:44: ERROR[main]: ....minetest/mods/animals_modpack/adv_spawning/internal.lua:294: in function 'quota_leave' 16:51:44: ERROR[main]: ....minetest/mods/animals_modpack/adv_spawning/internal.lua:224: in function <....minetest/mods/animals_modpack/adv_spawning/internal.lua:180> 16:51:44: ERROR[main]: /usr/share/minetest/builtin/game/register.lua:348: in function </usr/share/minetest/builtin/game/register.lua:336>

@fifthecard that backtrace is supposed to impossible ;-). Can you give more information how to trigger? what's your environment? what cpu what os, any virtualization or unstable system clock?
Or at least a few more lines of debug.txt prior error ;-)

According to that assert time on your machine went backwards

+ Spoiler

I am using carbone game but have tried on standard minetest with no other mods as well and get the same error. I am running this on a virtual machine on beefy computer but I can try and run this outside of the virtual machine. Setup is I7-4790 16GB ram with 4 dedicated to virtual machine. OS is Arch Linux with a git build of minetest on the 22nd with leveldb support. I also tried a build without leveldb to see if that could have been an issue. I will double check the clock sync issue to verify and also try to host outside of the virtual machine.

by **sapier** » Sat Jul 26, 2014 13:12

I don't think leveldb is involved... Virualization could be ... I don't like it but I'll change that assert to a warning. Basicaly time running backwards breaks mobfs limitation of CPU usage. You may get way more CPU usage then the targeted maximum of 100ms per server step.

by **fifthecard** » Sat Jul 26, 2014 16:06

I tried outside of the virtual machine and got the same error.

by **sapier** » Sun Jul 27, 2014 20:16

fifthecard could you change the assert to print the value instead of asserting? do you have default settings or did you e.g. enable multiple emerge threads?

by **fifthecard** » Mon Jul 28, 2014 00:39

When I change assert to print I get console spam with true.

I don't see any settings to allow multiple emerge threads.

Active Block Range

If I configure on my server that active_block_range is only 1, how does this impact the mobf monsters? I guess that would mean that only monster 8 nodes away (from the player) could attack, right?

by **sapier** » Mon Jul 28, 2014 20:30

@lotek yes but there will be major issues with mob spawning too as spawners are entities too. Chance there will be any active spawner within that range is quite small so. Result may be no mobs spawning at all.

by **ExeterDad** » Mon Jul 28, 2014 21:29

Good stuff lotek and sapier... I've wondered about this as well. Thanks :)

by **Giack Frichitichi** » Mon Aug 04, 2014 18:31

Can you add wool like kill result for sheeps?
At 43rd line you can change in this way:

Code: Select all: kill_result={"wool:white","animalmaterials:meat_lamb 2"},

by **atam7** » Mon Aug 04, 2014 22:04

I was wondering if you could tell me how to make the guard mobs friendly to all players but attack all hostile mobs? or could you add the ability for admins to spawn mobs to guard places from hostile mobs that are trying to harm player. something like guards in the elder scrolls series. thank you for your time!

by **atam7** » Mon Aug 04, 2014 22:08

or if there is a mod that does this, cold you please post a link. thank you!

by **sapier** » Tue Aug 05, 2014 17:16

atam7 you can configure a guard to attack those factions unfriendly to players that's most likely what you want

Edit1:
I just updated to 2.3.92, the only change is a new advanced_spawning version packaged, 2.3.92 is most likely the 2.4 version I'm gonna release this weekend.

by **atam7** » Tue Aug 05, 2014 23:02

can you tell me how to do that sapier? have virtually no programing experience. I can only find were to change what factions they are in, not what they are hostile to. where would they location of the file that determines what they are hostile to? could you give me as much info as possible. thank you very much in advance!

by **sapier** » Wed Aug 06, 2014 20:31

atam7 first you need to install the factions mod (make sure you get the new version provided by me)
next enter /mobf in chat window
you should see a "factions" tab
there you can create and configure factions e.g. a faction "my_guards"
next you can configure how other factions behave to that faction, there are some predefined ones by mobf e.g. monsters

once you did configure the faction you have to rightclick your guard and add it to this faction.

that's all ;-) no need to programm anything

by **atam7** » Sun Aug 10, 2014 17:06

Thank you for all the help sapier:) but I am still getting nowhere. I set the hireling to player relation to 1000 and hireling to monster relation to -1000 but guards still attack me

by **atam7** » Sun Aug 10, 2014 17:15

My intention is to get the guards to be friendly to all players and hostile to everything that is hostile to players (I assume monsters faction covers that).
I won't be able to use minetest for about a week.

Thank you for your time!

by **sapier** » Sun Aug 10, 2014 17:17

@atam7 For what I remember range is -100 to +100 ;-) seems like a check is missing to prevent invalid values.

Finally ... Animals modpack 2.4 did arrive. ... why not "mobf" ... well, mobf is the mob engine but the release contains spawning the mobs and factions mod so calling it that way would've been wrong. Mobf 2.5 will be split even more, animals will be moved from core to a separate repository.
Have fun!

by **lotek** » Sun Aug 17, 2014 09:49

I use now the new animals_modpack, factions and the newly adv_spawning (hope thats right) from your git account. Also I did a while a go a /clearobject and needed to use the "secondary spawning" features to get the animals back. Now, animals (wolfs, sheeps, cows, etcetera) are getting spread over the exist map again, but what I missing are vombies and other monsters. On newly generated maps vombies get spawned...

* Normal should this cpu intensive 2nd spawning add those mobs, too - right?
* Is with this new adv_spawning any help to respawn on generated maps?

thanx for your effort to build this great mod ;)
