Ok. i've got a command registered:

public void onInitialize() {

        CommandRegistrationCallback.EVENT.register((dispatcher, registryAccess, environment) -> {
            LiteralCommandNode<ServerCommandSource> PlayerChatRangeMethodNode = CommandManager
                    .literal("PlayerChatRangeMethod")
                    .requires(source -> source.hasPermissionLevel(4))
                    .then(argument(MethodArgumentName, IdentifierArgumentType.identifier()))
                    .executes(this::PlayerRangeMethodCommand)
                    .build();

            dispatcher.getRoot().addChild(PlayerChatRangeMethodNode);
        });
    }

    private int PlayerRangeMethodCommand(CommandContext<ServerCommandSource> context) {
        Identifier methodName = IdentifierArgumentType.getIdentifier(context, MethodArgumentName);
        context.getSource().sendFeedback(() -> Text.literal("called /PlayerRangeMethod with argument " + methodName), false);

        return 1;
    }

At the moment, for testing, it doesn't care what identifier is passed but when i try to pass an identifier, say minecraft:stone, i get this error:

Unknown or incomplete command, see below for error
...raft:stone<--[HERE]

I assume I am getting something wrong about how to pass identifiers

#

your executes() needs to be chained to argument()

#

do you mean this?

.literal("PlayerChatRangeMethod")
.requires(source -> source.hasPermissionLevel(4))
.then(argument(MethodArgumentName, IdentifierArgumentType.identifier()))
.argument(this::PlayerRangeMethodCommand)
.build();

because my IDE does not like that

why not

slender quail Oct 29, 2024, 2:56 AM

#

no, you're chanining a new argument

#

chain an executes(...)

#

slender quail chain an executes(...)

you mean this?

.literal("PlayerChatRangeMethod")
.requires(source -> source.hasPermissionLevel(4))
.then(argument(MethodArgumentName, IdentifierArgumentType.identifier())
        .executes(this::PlayerRangeMethodCommand)
)
.build();
