What you have shown is an array, when you are treating it as a dictionary.
A dictionary allows you to access values by keys:
local Dict = {
["Apples"] 5,
["Dogs"] = 2,
["Name"] = "HOLAGD_YT"
}
print(Dict["Apples"]) -- 5
print(Dict["Dogs"]) -- 2
print(Dict["Name"]) -- HOLAGD_YT
while a table allows you access values by index (numerical keys)
local Table = {
"Apples",
"Dogs",
"Name"
}
print(Table[1]) -- Apples
print(Table[2]) -- Dogs
print(Table[3]) -- Name
To find if a value exists in a table, you can use table.find(TABLE, VALUE)
i.e.
if table.find(tracks, "lola") then
-- code goes here
end
thansk!!! now how can i create keys from script?
i was using table.insert to insert a text value
random = math.random(1, #tracksFolderOnTable)|
local text = tracksFolderOnTable[random].Name|
table.insert(tracksTable, {text})|
You can just do this:
local dict = {}
dict["Apples"] = 5
print(dict["Apples"]) -- 5
