Tool for Lua Checking?

[Gladbach]

Hey,
since nowadays its very important to have clean Lua scripts, I wanna know, if there is any tool which checks the usage of lua scripts.

 

[Cykotitan]

what exactly?

 

[Gladbach]

Well, if you download a datapack with real map, you will recognize that many scripts are really bad written, many errors appear and and and.. But sometimes there is no error message, but still scripts can use loads of cpu usage .

 

[Cykotitan]

no such tool. gotta check them manually. also ^ happens a lot less often than you might think

 

[Gladbach]

So what is the best way, to improve the scripts. Should I read now all one by one, to find the so heavy cpu usage scripts?

Logical erros(or what the term was) wont be picked up.

i would first check stuff that executes constantly, like globalevents and their intervals.
and then check what players are doing at the time CPU usage increases

they could be abusing npc shops, or stacking many items to ground .

 

[Gladbach]

Well I doubt that items will be stacked constantly on the ground since the CPU usage increases if more players are online. And what exactly can they abuse in NPC shops, if i already added exhaustion?

 

[Cykotitan]

many backpacks in other backpacks and it's normal for cpu usage to increase as more players are online

 

[Gladbach]

Ye but its already insane at like 60 players, that a CPU usage peak of 60% has been reached at 2.7ghz. You know any bad scripts in the thunderion package?

 

[Cykotitan]

try to compile the server yourself, unless you already did.
use -O2 for optimization

 

[Gladbach]

Well I haved compiled rev3777, which is for linux. I didn't used the thunderion source (don't know if there were source included). And what does - O2 mean?

 

[Cykotitan]

it's a G++ (compiler) parameter for higher optimization

it's a G++ (compiler) parameter for higher optimization

if so, why isn't it enabled by default?

 

[Cykotitan]

It is, in makefiles for 0.4

 

[richux]

ahh, but that's in Makefile.mingw, what means I need to compile different than just usual ./build.sh?

 

[Gladbach]

it's a G++ (compiler) parameter for higher optimization

And what exactly does it help for?

 

[Gladbach]

Bump, disabled all globalevents with intervalls. Didn't helped out. Any scripts which are written badly at thunderion? Please help me.

 

[Cykotitan]

remove any -g parameters (also -ggdb or -g3) and compile again with -O2. debug binaries are heavier on the CPU, atleast on windows

 

[richux]

nvm
