Call another function from different files into the same resource


Recommended Posts

Hello dear community, 

First of all, I know that i can solve my problem with a simple trigger, but Im a bit curious and I would like to know why this is not working or which one is the best way to call it.

Well, I have done a template to use it multiple times in the same resource but just changing a variable, so, some of them uses the same fucntion name but i just used local (This should prevent interaction issues) 

So I realized the is only executed the last one added in meta.xml

I know that Im explaining very very bad, but I have done an example that it understable (I think so)

--## META.XML
<script src="file1.lua" type="client" cache="false" />
<script src="file2.lua" type="client" cache="false" />
<script src="file3.lua" type="client" cache="false" />  --THE LAST ONE IS ONLY EXECUTED

--## MAIN FILE
showContent(1) --THIS WONT WORK
showContent(2) --THIS WONT WORK
showContent(3) --WORKING DUE TO IS THE LAST ONE IN META.XML

--## 1ST FILE
local fileID = 1
local function sayHI()
	outputChatBox("HI WORLD FROM FILE 1")
end

function showContent(id)
	if fileID == id then
		sayHI()
	end
end

--## 2ND FILE
local fileID = 2
local function sayHI()
	outputChatBox("HI WORLD FROM FILE 2")
end

function showContent(id)
	if fileID == id then
		sayHI()
	end
end

--## 3RD FILE
local fileID = 3
local function sayHI()
	outputChatBox("HI WORLD FROM FILE 3")
end

function showContent(id)
	if fileID == id then
		sayHI()
	end
end

I hope you can bring me a hand with this simple doubt.

Thanks for reading, best regards.

A function name is just a variable.

When creating a function with the same name, you will overwrite that variable/function.

 


 

You can solve your problem with a table.

Main file:

showContent = {}


setTimer(function () -- add a little delay so that the function can be added before calling it.
	showContent[1]()
	showContent[2]()
	showContent[3]()
end, 100, 1)

For each other file:

local fileID = --[[...]]
showContent[fileID] = function ()
	sayHI()
end

Alright, thats the other way I supposed to use.

However, whats the efficence of using that way ?

Is there another efficent way? (Not adding all the content in the same file)

Thanks in advance and best regards.

If you want to create environments, OOP would be another way and maybe also use a meta table to inherit properties

 

But I can understand that it might be a little bit complex, especially when you are doing it like this:

showContentConstructor = {
	new = function (self)
		local newShowContent = {}

		setmetatable(newShowContent, self.metaTable)

		return newShowContent
	end,
	prototype = { -- initial properties
		text = "<please set text>",
		sayHI = function (self)
			return outputChatBox(self.text)
		end
	}
}

-- Set the meta table as lookup table when the information is not found in the instance table
showContentConstructor.metaTable = {__index = showContentConstructor.prototype}

-- create new instances
showContent1 = showContentConstructor:new()
showContent2 = showContentConstructor:new()

showContent1:sayHI()
showContent1.text = "test1"
showContent1:sayHI()

showContent2:sayHI()
showContent2.text = "test2"
showContent2:sayHI()

 

Unfortunately there are no options without tables afaik, so you really need to be able to understand the basics of tables, if you want to build this.

So I recommend doing it the way as in my previous reply, which should be easy to do.
