I am making a music player and I need to store all of the songs id's. I know there are String Value but this cannot store an array.
How can I store the song id's which also need to be individual to the client/user?
Lua has structures called Tables, which are more like Structs than anything else but behave like arrays when you want them to:
songIds = {1251366, 136134727, 125134, 1251366}
As for having different stored IDs for each player, the solution to that depends on what you're doing with this data.
