Im trying to create variables like these using a for loop..
TPidL1 = Load('TPidL1', '')
TPidL2 = Load('TPidL2', '')
TPidL3 = Load('TPidL3', '')
TPidL4 = Load('TPidL4', '')
TPidL5 = Load('TPidL5', '')
After reading other posts, I tried this but no luck
for z = 1, 5, 1 do
"TPidL"..z = Load('TPidL'..tostring(z), '')
end
Any ideas how I could approach this better?
thanks
Just use a regular table instead of messing with globals..?
TPidLs = {}
for z = 1, 5, 1 do
TPidLs[z] = Load('TPidL' .. tostring(z), '')
end
you can do this via the global namespace _G:
for z = 1, 5 do
_G["TPidL"..z] = "TPidL"..z
end
print(TPidL1,TPidL2,TPidL3,TPidL4,TPidL5)
Well, AFAIK it's not possible directly, but Lua being quite flexible, there is a way. The key thing is to understand that all the global variables and functions are simply stored in a simple Lua table named _ENV. A simple example to highlight this:
MyVariable = "Hello"
for Key, Value in pairs(_ENV) do
print(Key,Value)
end
This code will show something like this:

That's it: _ENV is simple table which make the link between the function name and its implementation and between variable name and its value. Regarding you question, I have absolutely no idea what is the definition of the Load function.
But if you want to generate variable names dynamically, you could try:
for Index = 1, 5 do
_ENV["MyVariable"..Index] = Index
end
print(MyVariable1)
print(MyVariable2)
print(MyVariable3)
print(MyVariable4)
print(MyVariable5)
It should print:
> print(MyVariable1)
1
> print(MyVariable2)
2
> print(MyVariable3)
3
> print(MyVariable4)
4
> print(MyVariable5)
5
>
