【网络通信】宝宝指令：召唤、跟随与攻击的协议

---召唤：校验后引擎生成宝宝
function Pet.summon(actor)
    local player = class(actor)
    if not player then return false end
    -- 召唤兽数量上限：道士 2 只
    local cnt = Pet.countOf(actor)
    if cnt >= 2 then
        sendmsg(actor, 1, "召唤兽数量已达上限")
        return false
    end
    if not checkitemw(actor, "魔法药", 5) then
        sendmsg(actor, 1, "蓝量不足，无法召唤")
        return false
    end
    takeitem(actor, "魔法药", 5, 0, "召唤消耗")
    recallmob(actor, "麒麟", 1)
    sendmsg(actor, 1, "麒麟已听候差遣")
    return true
end

---指令协议：跟随、攻击、停留
function Pet.command(actor, petIdx, cmd, targetId)
    local player = class(actor)
    if not player then return false end
    -- 归属校验：只能指挥自己的宝宝
    if not Pet.ownedBy(actor, petIdx) then
        sendmsg(actor, 1, "宝宝归属不符")
        return false
    end
    local pet = Pet.of(actor, petIdx)
    if cmd == "follow" then
        pet.mode = "follow"
        sendmsg(actor, 1, "宝宝已切换为跟随")
    elseif cmd == "attack" then
        pet.target = targetId
        pet.mode = "attack"
        sendmsg(actor, 1, "宝宝出击！")
    elseif cmd == "stay" then
        pet.mode = "stay"
        sendmsg(actor, 1, "宝宝原地待命")
    end
    return true
end
