@xoft I think it loads them all together, because it can check for not defined global values that are accessed. Example block type E_BLOCK_SIGN doesn't exist and it would warn then.

I want to export a class and a few methods over ManualBindings.cpp to lua, but have a few problems . I have now created a cTestclass and exported it.

On startup the server crashes at this line. Hope that someone can point out my mistake  

[xoft]

Classes that are purely-manually-exported need to be registered with ToLua before adding functions into them, Have a look at how the cNetwork does it:
https://github.com/cuberite/cuberite/blo...1237-L1246

Code:

local tb = {}
tb[nil] = ""

Can you elaborate on this a bit more? You put this into a command handler, or as a plugin global, or what? How does it crash the server?

[Seadragon91]

Copy this 2 lines into the Initialize function of a plugin. Start the server and then run command reload a few times.

That doesn't seem to be related to the two lines of Lua code. I have a feeling it will crash even without them.

[Seadragon91]

You are correct. If the plugin has invalid lua code, then doing the steps above will cause an crash too.

[xoft]

That's worth a bugreport on GitHub, then

Oh dear, one can't even enjoy a moment of peace. I've been at home for the last three days, took a vacation from work because I feel sick (but not sick enough to go to a dogtor). And now I had to go to the vet with my cat, he was unlucky in some cat street fight and got a bad wound just behind his ear. Now he has a "satellite dish" around his neck And he seems to hate me for it.

Anyone has problems with github? Maybe DDoS again...
