FERPChatCommand GiveXP;
GiveXP.Command = TEXT("givexp");
GiveXP.Description = FText::FromString("Grant XP to a player");
GiveXP.RequiredRole = ERPPlayerRoleEnum::GameMaster;

// Add typed arguments
FERPCommandArgument PlayerArg;
PlayerArg.Name = TEXT("player");
PlayerArg.Type = ERPArgTypeEnum::PlayerName;  // Auto-complete with online players
PlayerArg.bRequired = true;
GiveXP.Arguments.Add(PlayerArg);

FERPCommandArgument AmountArg;
AmountArg.Name = TEXT("amount");
AmountArg.Type = ERPArgTypeEnum::Integer;
AmountArg.bRequired = true;
GiveXP.Arguments.Add(AmountArg);

ChatSub->RegisterCommand(GiveXP);

Handling Custom Commands

ChatSub->OnCustomCommandExecuted.AddDynamic(this, &AMyGM::OnCommand);

void AMyGM::OnCommand(const FString& CommandName, const TArray<FString>& Args, APlayerState* Sender)
{
    if (CommandName == TEXT("givexp"))
    {
        // Args[0] = player name, Args[1] = amount
    }
}

Inline Emotes

Wrap action text in configurable delimiters (default *...*):

I whisper: *leans in close* Can you hear me?

Produces two segments:

1. Say: "I whisper: "
2. Emote: "leans in close" (never language-corrupted, styled differently)
3. Say: " Can you hear me?"

Autocomplete

The autocomplete system provides up to 6 suggestions:

1. After / — channel commands, language commands, custom commands (role-filtered)
2. After command + space — argument values based on type

TArray<FString> Suggestions = ChatComponent->GetAutoCompleteSuggestions(CurrentInput);
