如何让Mineflayer机器人跟随玩家时冲刺？解决相关问题

问题描述 #

我正在开发一款Mineflayer机器人，设定为跟随玩家并发起攻击，但目前存在两个问题：

• 当与玩家距离过远时，机器人会停止跟随；
• 机器人在搭桥过程中会出现掉落情况。
  同时需要实现机器人跟随玩家时保持冲刺状态。

原始代码 #

const { versions } = require('minecraft-data')
const MinecraftData = require('minecraft-data')
const mineflayer = require('mineflayer')
const { pathfinder, Movements, goals } = require('mineflayer-pathfinder')
const GoalFollow = goals.GoalFollow
const pvp = require('mineflayer-pvp').plugin
const armorM = require('mineflayer-armor-manager')

const bot = mineflayer.createBot({
    host: 'EventWG.aternos.me',
    username: 'bot'
})

//Follow the player
function followPlayer() {
    
    bot.on('chat', (namee, msgg)=>{
        const player = bot.players[namee]
        if (msgg == "attack") {
            bot.chat("ok " + namee)
            bot.chat("/effect give @p minecraft:resistance 111111 255")
            if (!player || !player.entity){
                bot.chat("I can't see you " + namee) 
                return
            }
        
            const data = require('minecraft-data')(bot.version)
            const movements = new Movements(bot, data)
            bot.pathfinder.setMovements(movements)
        
            const goal = new GoalFollow(player.entity, 2)
            bot.pathfinder.setGoal(goal, true)
        
            setInterval(() => {
                const playerFilter = p => p.type === "player"
                const playerr = bot.nearestEntity(playerFilter)
                bot.pvp.attack(player.entity)
                const sword = bot.inventory.items().find(item => item.name.includes('sword'))
                if(sword) bot.equip(sword, "hand")
            }, 2000);
        
        }
    })
}

bot.on('spawn', lookAtPlayer)
bot.on('spawn', followPlayer)

问题修复与功能实现方案 #

1. 解决远距离停止跟随问题 #

• 原始代码未加载pathfinder等核心插件，导致寻路功能失效，需补充插件加载逻辑；
• 避免在chat事件内重复注册定时器，改用全局变量管理状态，防止多次触发逻辑冲突；
• 新增玩家实体消失时的清理逻辑，确保机器人能重新响应指令。

2. 修复搭桥掉落问题 #

自定义Movements参数，优化搭桥行为：

• 调整maxDropDown允许小幅度掉落，适配搭桥场景；
• 开启allowFreeMotion提升移动灵活性；
• 确保canPlaceBlocks为true，保证机器人能放置方块搭桥。

3. 实现跟随冲刺状态 #

通过physicTick事件实时检测机器人移动状态，控制冲刺按键：

• 当机器人处于移动状态且存在目标玩家时，持续按下冲刺键；
• 停止移动或目标消失时，关闭冲刺状态。

修改后的完整代码 #

const mineflayer = require('mineflayer')
const { pathfinder, Movements, goals } = require('mineflayer-pathfinder')
const GoalFollow = goals.GoalFollow
const pvp = require('mineflayer-pvp').plugin
const armorManager = require('mineflayer-armor-manager')

const bot = mineflayer.createBot({
    host: 'EventWG.aternos.me',
    username: 'bot'
})

// 加载核心插件
bot.loadPlugin(pathfinder)
bot.loadPlugin(pvp)
bot.loadPlugin(armorManager)

let targetPlayer = null
let attackInterval = null

// 自定义移动配置，修复搭桥掉落问题
function createCustomMovements() {
    const data = require('minecraft-data')(bot.version)
    const movements = new Movements(bot, data)
    movements.maxDropDown = 1 // 允许搭桥时小幅度掉落
    movements.canPlaceBlocks = true // 允许放置方块搭桥
    movements.allowFreeMotion = true // 提升移动灵活性
    return movements
}

// 实时控制冲刺状态
function handleSprint() {
    const isMoving = bot.pathfinder.isMoving()
    bot.setControlState('sprint', targetPlayer && isMoving)
}

// 启动跟随与攻击逻辑
function startFollowAndAttack(player) {
    targetPlayer = player.entity
    const movements = createCustomMovements()
    bot.pathfinder.setMovements(movements)
    
    // 设置跟随目标，保持2格距离，持续追踪
    const goal = new GoalFollow(targetPlayer, 2)
    bot.pathfinder.setGoal(goal, true)
    
    // 清理旧定时器，避免重复执行
    if (attackInterval) clearInterval(attackInterval)
    
    // 高频执行攻击与装备逻辑（500ms间隔更流畅）
    attackInterval = setInterval(() => {
        if (!targetPlayer) return
        bot.pvp.attack(targetPlayer)
        const sword = bot.inventory.items().find(item => item.name.includes('sword'))
        if (sword) bot.equip(sword, 'hand')
    }, 500)
    
    // 绑定冲刺控制事件
    bot.on('physicTick', handleSprint)
}

// 聊天指令触发
bot.on('chat', (name, msg) => {
    const player = bot.players[name]
    if (msg === 'attack') {
        bot.chat(`ok ${name}`)
        bot.chat('/effect give @p minecraft:resistance 111111 255')
        
        if (!player || !player.entity) {
            bot.chat(`我看不到你 ${name}`)
            return
        }
        
        startFollowAndAttack(player)
    }
})

bot.on('spawn', () => {
    bot.chat('已上线，输入attack让我跟随攻击你')
})

// 目标玩家消失时清理逻辑
bot.on('entityRemoved', (entity) => {
    if (entity === targetPlayer) {
        targetPlayer = null
        bot.pathfinder.stop()
        if (attackInterval) {
            clearInterval(attackInterval)
            attackInterval = null
        }
        bot.setControlState('sprint', false)
        bot.removeListener('physicTick', handleSprint)
    }
})
