[SOLVED] Attributing global function to table

[pauls313]

I want my game to be very flexible, so no item will have fixed values. For example, a gun can work as if it were a sword. I wanted to do this by making a list of functions with each behavior

function crowbar()
...
end
function gun()
...
end

And then, I'd instantiate the items like this

item[1].func = gun()

So every frame I could run the item[1].func() so it would act like the behaviour of the function. But I'm not finding any way of doing this, all I saw were examples where you declared the function inside the table, not outside. Is there no other way?

Your example would work as intended if you assigned the actual function instead of the result of the function call to item[1].func

Code: Select all

item[1].func = gun -- no parentheses

Your also might want to look into a design pattern called Entity-Component-System.

Something like this?

Code: Select all

function crowbar()
	local item = {
		damage = 10,
		swingSpeed = .4
	}
	function item:use()
		-- do whatever
	end
	return item
end

-- then assign and use it
item[1] = crowbar()
item[1]:use()

That's perfect! Thanks.
