Dispatch a command

const { CommandDispatcher, literal, argument, string, Suggestions } = require("node-brigadier")

class BlockPos { constructor(x = 0, y = 0, z = 0) { this.x = x; this.y = y; this.z = z; } parse(reader) { this.x = reader.readInt(); reader.skip(); this.y = reader.readInt(); reader.skip(); this.z = reader.readInt(); return this; } listSuggestions(context, builder) { return Suggestions.empty(); } getExamples() { return "1 2 3" } }

const dispatcher = new CommandDispatcher();

dispatcher.register( literal("fill").then( argument("pos1", new BlockPos()).then( argument("pos2", new BlockPos()).then( argument("block", string()).executes(context => { console.log(context.getArgument("pos1", BlockPos)) console.log(context.getArgument("pos2", BlockPos)) console.log(context.getArgument("block", /String/ 3)) return 0; }) ) ) ) )

const parsedCommand = dispatcher.parse("fill 3 4 5 10 11 12 air", {}) try { dispatcher.execute(parsedCommand); } catch (ex) { console.error(ex.getMessage()); }

// Console // BlockPos { x: 3, y: 4, z: 5 } // BlockPos { x: 10, y: 11, z: 12 } // air
