Im using "windfield" library. Love2d version - latest 11.2
Line " world = wf.newWorld(0, 0, true) " gives me error from windfield itself.
(edited to invalid line)
Code: Select all
Error

Welcome to the forums.
It's slower than Discord.
Be patient.

If you don't provide your code I can't help you.

When I try that, I get this error instead:
Code: Select all
Error: main.lua:1: attempt to index global 'wf' (a nil value)
stack traceback:
[string "boot.lua"]:637: in function '__index'
main.lua:1: in main chunk
[C]: in function 'require'
[string "boot.lua"]:475: in function <[string "boot.lua"]:311>
[C]: in function 'xpcall'
[string "boot.lua"]:645: in function <[string "boot.lua"]:639>
[C]: in function 'xpcall'
which is expected because 'wf' is not defined, and I bet everyone who tries it will get the same error as me, therefore nobody can possibly figure out why you are getting a different error other than the expected one.
If that is not your whole code, can you show your whole code so we can understand which of the virtually infinite possibilities can be causing the problem?

I tried this:
Code: Select all
local wf = require 'windfield'
world = wf.newWorld(0, 0, true)
No error.
It's not possible for anyone to help any further without seeing the code that leads to the situation that you're describing. If you don't want to provide it, you'll have to deal with it by yourself.

Looking at the source of it, it should work the way you called it... unless adn started to refactor it and didn't finish or something.
A shot in the dark: you put local wf = require whatever in love.load, and you're trying to call wf from elsewhere... but as pgimeno said, post more code.

Well, idk how it works, but i fixed.
I had this line:
Code: Select all
self.world:setCallbacks(beginContact, endContact, preSolve, postSolve)
That line was at
few lines after original problem:
Code: Select all
self.world = wf.newWorld(0, 0, true)
Somehow Lua interpreted "setCallbacks" at the same time as creating new world. Last line that debugger has reach was creating world! I was not expected that line after error can cause problems O_o
I sounds stupid but i cant explain this...
