Attach an array to another array

Hey there!
In my current code I have 2 arrays included:

    @editable SpawnerArray : []player_spawner_device = array{}
    @editable MenuArray : []cinematic_sequence_device = array{}

I want for every player_spawner_device a specific cinematic_sequence_device.
For example if a player spawns on a player spawner device with the index 0, it should show the cinematic sequence with the same index & so on…

Greetings!

Why not use a Map instead? I would suggest taking a look at TMap<KeyType, ElementType>

Map Containers in Unreal Engine | Unreal Engine 5.1 Documentation

That way you can map players to cinematic sequence devices, such that given any player, you get their cinematic sequence device returned.

But isn’t that just for C++ & not for Verse? Because I can’t find anything similar to this in the Verse Glossar

Verse has built-in map data types which you use to define key value pairs. For example, if I wanted to map Ids to Players I could make:

# Create a map that holds an integer for every player variable
PlayersToID : [player]int = map{}

# If I wanted to acces a Player's ID
PrintPlayerID(Player : player) : void =
    # Here, we acces the id that corresponds to the player we passed in 
    # This ID gets assigned to PlayerID
    # Note that to access elements in a map, you must do so in an if expression
     if (PlayerID := PlayersToID[Player]):
          Print("Your player ID is {PlayerID}")

Now one important note is that you generally cannot create maps where the Key is a device, for example

# This throws an error, because devices are not comparable, and maps must
# have unique keys per entry,  which you must somehow be able to compare
SpawnersToCinematicsMap : [player_spawner_device]cinematic_sequence_device = map{}

You could make an array of type tuple(player_spawner_device, cinematic_sequence_device)

If you want it to be a bit more readable so you don’t need to type (0), or (1), you could make a class/struct

spawner_and_cinematic := struct:
    SpawnerDevice : player_spawner_device = player_spawner_device{}
    CinematicDevice : cinematic_sequence_device = cinematic_sequence_device{}

MyArray : []spawner_and_cinematic = array{}
