Calling A Function From A Table

[ElPunto]

Is There Anyway To Call A Function From A Table At All. I've Tried
To Insert The Function Name Into The Table With Arguments But It Returns A Nil Value.

Code?

Something like this perhaps?

[lua]
--Create a table
T_Functions = {);
T_Functions[1] = "a";
T_Functions[2] = "b";
T_Functions[1] = "c";

function Process(input)
--Based on input, do something different
if (input=="a") then
DoShitLikeThis();
elseif (input=="b") then
DoShitTheOtherWayAround();
else
DoShitLikeThat();
end
end

Process(T_Functions[1]);
Process(T_Functions[2]);
Process(T_Functions[3]);
[/lua]

Idiot, should have let him posted his code so we can see what he is doing wrong.

I'm assuming what you tried was
[lua]tab[1] = funcName( arg1, arg2 )[/lua]
where what you want to do is
[lua]tab[1] = funcName[/lua]

Oor, post an example, so he can see what he did wrote, or learn/Change the code.

This is a little something I did a while back, just an attempt at a truth-table sort of function call. I'm still not sure why I did it, and I don't know if it's more efficient than just an if tree, but it's certainly easier to add more possibilities.

SuperScript = {}
SuperScript.Item = 100


function SuperScript.GiveItem(num)
    SuperScript.Item = SuperScript.Item + num
    print("Added ".. num)
end

function SuperScript.TakeItem(num)
    SuperScript.Item = SuperScript.Item - num
    print("Subtracted ".. num)
end

local TT = {}

TT[00] = function() print("Nothing Happened") end
TT[01] = function(num) SuperScript.TakeItem(num) end
TT[10] = function(num) SuperScript.GiveItem(num) end
TT[11] = function(num) SuperScript.GiveItem(num) SuperScript.TakeItem(num) end
    
function SuperScript.CalcItem(give, take, number)
    local slot = (give * 10) + take
    TT[slot](number)
end

print("Before")
print(SuperScript.Item)

SuperScript.CalcItem(0,0,10)
SuperScript.CalcItem(0,1,5)
SuperScript.CalcItem(1,0,15)
SuperScript.CalcItem(1,1,50)

print("After")
print(SuperScript.Item)

Here is how you call a function from a table.

There are two ways, as shown in the code.

[lua]local t = {}
t.func = function(name) print("Hello, " .. name) end

-- Option 1
t.func( "Entoros" )

-- Option 2
t["func"]( "Entoros" )[/lua]
