Anyway I can do something like this? Basically I want to pass a variable’s memory address as a function argument instead of passing the variable itself.
local myVariable = 10
randomFunction(&myVariable)
function randomFunction(aMemoryAddress)
print(aMemoryAddress)
end
You cannot directly pass the in-memory address of a variable like you would in languages such as C or C++. Lua abstracts this all out to keep things simple and safe, however you can do this with tables.
Tables were my first though too, just thought there could be an easier way. Thanks anyways.
If you need to pass something by reference, only tables and fat userdata are done that way. Instead of wrapping a single value in a table, you should use upvalues.
local Value = 1
local function UpdateValue(NewValue: number)
Value = NewValue
end
Closures are very fast to create in Luau, but just don’t use them unless needed (signal callbacks can be static functions instead of lambdas, for example).
