So i'm trying to make a function run inside a Table, Here's my table:
Functions = {
[1] = Test("Hello!"),
}
And here's my simple function:
function Test(String)
print(String)
end
So yeah, how would I do it? I already tried doing this:
Functions[1]
But that didn't work .(Sorry if that's a dumb mistake, i'm not really good at scripting..)
Your first script segment can be evaluated like this:
Functions = {
[1] = Test("Hello!"),
}
--[1] is the same as this:
Functions = {Test("Hello!")}
--Test("Hello!") asks lua to run the function. Test calls 'print' but doesn't return anything, making this line evaluate to:
Functions = {}
Clearly this isn't what you want. If you want Functions[1] to print "Hello!", use an anonymous function:
Functions = {
[1] = function() Test("Hello!") end,
}
--Usage:
Functions[1]()
--Or don't use an anonymous function:
Functions = {
[1] = Test --Notice how we don't call it here, we just assign it to index 1 of the table
}
--Usage:
Functions[1]("Hello!")
--Or use Functions like a dictionary:
Functions = {}
Functions.Test = Test
--Usage:
Functions.Test("Hello!")
--If Functions is just supposed to be a list of functions, you don't need the [1] syntax; just do:
Functions = {
Test,
Test2,
function() print("Anonymous function") end,
--etc
}
--Functions[1] is Test, Functions[2] is Test2, etc
I setup my functions inside tables like this
local table = {
func = function()
print("hey look at me")
end
}
table.func()
I read the Wiki already... Is there a way to do it without making the actual function inside the table? I just want to call it from the table.
Should work then.
