'self' (a nil value)

[Saint'N Studios]

I'm using Goature's tutorial for the base of my game and it keeps on saying enttities/box.lua:23: attempt to index 'self' (a nil value).
I don't know how to fix it can i plz have help.

Please follow the guidelines. Make a .love file containing all of your code and assets and upload it, or we may not be able to help.
In this case, you probably used "." instrad of ":" when calling a function or vice versa.

I'm assuming your issue lies either here:

Code: Select all

if ent.update then 
	ent:update(dt)
end

or here:

Code: Select all

if ent.draw then 
	ent.draw()
end

You're mixing up '.' and ':' on the ent.update call. But without the .love file, I can't help any more than that.

Technically, he's not, since he's checking if the field exists or not, and even if it's a function that would require a self parameter to be passed first (that : would pass implicitly when called),

Code: Select all

if table:field then

is, to my knowledge, not allowed code.

That said, the error might be that he's mixing up the . and or : when one of the calls actually happen. (either update should be with a ".", or draw with a ":")
