Latest update breaks the Advanced Weapons mod.

I had to rollback to the previous version to start the server.

You are right, the last update does in fact break that mod. I have updated all my mods (at least on GitHub) except for adv_weapons (big update upcoming, the current version contains a handful of bugs and tons of missing features). This release is going to be huge (4k lines and counting) so it's taking some time.

Sounds interesting.

Any chance that things like the gatling gun can be used on monsters and not just on other players. I've played around with a detector grid around my factory and automated weapons would just be the bees knees.

Either way, I'm looking forward to what you've come up with.

Cheers and good luck with it

Where's the mod?

Modlib causes the luacontroller overheating with the simple interrupt example code from the mesecons site:
https://mesecons.net/luacontroller

Modlib causes the luacontroller overheating with the simple interrupt example code from the mesecons site:
https://mesecons.net/luacontroller

The example with the "worst" (shortest) interrupt I see there is

Code: Select all

interrupt(0.5, "a parameter")
print(event.iid) 

Using which I can not reproduce that bug - the luacontroller doesn't overheat. Modlib should hardly affect performance or interfere with mesecons by it's very nature.

You could try upgrading modlib.

I already use the master branch of modlib.

I get an error on game start[codeModError: Failed to load and run script from ~/.minetest/mods/modlib/init.lua:
Setting [mgv7_np_dungeons] is a group.
stack traceback:
[C]: in function 'to_table'
~/.minetest/mods/modlib/conf.lua:17: in function 'build_setting_tree'
~/.minetest/mods/modlib/init.lua:86: in main chunk
Check debug.txt for details.[/code]
Posted on the github tracker. Maybe it's because I changed some mapgen settings?

Edit: Confirmed that if I return noise settings to default, game loads without issue

This is an issue with minetest.settings:to_table(). Please report it at the engine bugtracker.

This has finally been fixed by luk3yx. You can get the newest releast (tag: rolling-73) from GitHub.

I can't seem to get modlib.minetest.decode_png to work.

Code adapted from modlib_test

Code: Select all

local path = modlib.mod.get_resource("drawmap", "maps")
for _, filename in pairs(minetest.get_dir_list(path, false)) do
    if modlib.text.ends_with(filename, ".png") then
        local file = io.open(path .. "/" .. filename, "r")
        local png = modlib.minetest.decode_png(file)
        file:close()
    end
end

Here's the bug I'm getting:

This assertion is triggered by the file ending prematurely, in this case, before 8 bytes of signature have been read. Are you sure that the file handles you are passing are correct?
