So I’m pretty new to lua and programming in general, and I’m having a lot of trouble with tables. I’m working on an app that downloads xml files and converts them into a news app. I’ve understood tables to be like structs in c++. How can a save a list of tables in lua, as I would have an array of structs in c++
The issue that I am having Is once I create a table that has a title, body, and image; I cant access it anymore. How can I iterate trough the tables in the class?
Yes, you’re right, tables can be used like a struct in C. And tables can also be used like an array. And since you can nest tables indefinitely, you can create an array of structs like this:
[lua]
local myArray = {}
for i=1,10 do
– There’s no need to actually define myStruct here; these two lines could be collapsed into one. I just separated them into two to emphasize how we’re creating an array of structs
local myStruct = {title=“some title”, body=“some body”, image=“filename.png”}
myArray[i] = myStruct
end
[/lua]
And you could iterate through the array like this:
[lua]
for i = 1,10 do
print(myArray[i].title, myArray[i].body, myArray[i].image)
end
[/lua]
Hope this helps.
