Can you send a function with parameters as a parameter of a different function?

[lgregvcxs]

I’m trying to make a function that runs a different function using parameters depending on certain conditions. I know that I can do this with a function without parameters, but I want to be able to do this with a function with parameters. Is this possible? If not, what is a different method that could work?

Is this what you mean?

local function returnsNumber()
 return 2
end

local function printNumber(a)
 print(a)
end

printNumber(returnsNumber())

You mean something like this?

function executeFunction(func, arg1, arg2)
    return func(arg1, arg2)
end

function addNumbers(x, y)
    return x + y
end

local result = executeFunction(addNumbers, 5, 3)

print(result)

printNumber(returnsNumber)* is the correct way to call the function, it will error because of the parentheses

I’m thinking of something like this, but if you change the amount of arguments in the table, the amount of arguments in the function called by the execute function will respond accordingly.

local args = {
	arg1 = 5,
	arg2 = 6,
	arg3 = 10
}

function add(num1,num2,num3)
	print(num3+num1+num2)
end

function Executefunc(fuc,args)
	fuc(args.arg1,args.arg2,args.arg3)
end

Executefunc(add,args)

Try this

local args = {
    arg1 = 5,
    arg2 = 6,
    arg3 = 10
}

function add(num1, num2, num3)
    print(num3 + num1 + num2)
end

function Executefunc(func, args)
    func(unpack(args)) 
end

Executefunc(add, args)

Nope. Didn’t work. I appreciate the suggestion tho.

Try this

local args = {
   [1] = 5,
   [2] = 6,
   [3] = 10
}

function add(...)
   local args = unpack({...})
   local sum = 0
   for i = 1, #args do 
      sum += args[i]
   end
   return sum
end

function Executefunc(func, args)
   print(func(args))
end

Executefunc(add, args)

Your solution worked! Although this seems to only work with the example that I provided, and it wouldn’t work with the function I had in mind (at least I don’t think so since I don’t really know what you did lol), you still found a solution so thank you!

[astraIboy (The Batman)]

Yeah thats what I was gonna say, like since your problem is kinda of more advance your going to need to probably do your own logic for it depending on what your doing, glad it worked for you though, good luck!

Do you need to pass the function as an argument? Or can you just fire the function from inside the function.
