[lua]local foo

function setFoo

foo = “goo”

end[/lua]

Hi,
Could someone tell me if in the above code if im setting the local variable foo to “goo” or if I’m setting a globally accessible variable to “goo”

Thanks

You are setting the “local foo” defined just above it to “goo”. If there is also a global “foo”, it won’t be accessed from there because the local version is what is in scope when that assignment happens.

Super, Thanks Rob that makes sense.

So if it just looked like this…

function setFoo  
   
foo = "goo"  
   
end

… Would I be setting a global variable called “foo” to “goo”

Thanks
