# 为小游戏地图添加引导
我们来制作一个小游戏玩法地图DEMO，并且为这个地图的大厅中添加一些引导。

# 在大厅添加NPC
先简单制作一个大厅场景，地图名为《丛林激流》，是一个轻松的“水上竞速”玩法地图；而游戏场景设定是游乐园风格，所以在大厅添加了多个游乐园会出现的小摊，引导NPC将放置于此。
在大厅内添加多个小动物形态的NPC：熊猫、鹦鹉、狼。
有游戏背景或世界观的玩法地图，将所有的游戏元素风格统一化也是很重要的；
# 制作UI添加引导手册
引导手册可以有很多方式体现，最简单的方法就是将引导文字写在【书与笔】上并放在游戏比较“显眼”的位置即可。不过这次我们放置了NPC，所以需要制作UI，在玩家与NPC交互的时候，显示UI。
打开我的世界开发工作台的界面编辑器，制作引导手册界面和欢迎界面；
欢迎界面主要填充一些对于地图的基本介绍和简单引导；当然，实际需要什么内容，还是根据引导设计和开发者习惯来决定。
引导手册则需要多页，将玩法内容罗列在此供玩家翻阅、学习。大部分情况下，小游戏地图不怎么需要引导手册，因为无论是场景还是玩法都是有局限性的，玩家在游玩的过程中必定会发现和体验到，全部的内容被玩家了解后，在真正游玩的时候可能会丧失一定的新鲜感。
制作好UI后，我们需要将UI与NPC“连接”起来：
创建UI的脚本文件FlumeRideInfoUI.py，并继承ScreenNode类
# -*- coding: utf-8 -*-
import mod.client.extraClientApi as clientApi
ViewBinder = clientApi.GetViewBinderCls()
ViewRequest = clientApi.GetViewViewRequestCls()
ScreenNode = clientApi.GetScreenNodeCls()
class FlumeRideInfoUI(ScreenNode):
def __init__(self, namespace, name, param):
ScreenNode.__init__(self, namespace, name, param)
创建FlumeRideServerSystem.py、FlumeRideClientSystem.py
# -*- coding: utf-8 -*-
import mod.server.extraServerApi as serverApi
ServerSystem = serverApi.GetServerSystemCls()
class FlumeRideServerSystem(ServerSystem):
def __init__(self, namespace, systemName):
ServerSystem.__init__(self, namespace, systemName)
# 提前将放在大厅的NPC生物ID获取到并保存在这里，用于判断玩家交互的NPC
self.npcIdList = {"panda": "-85899345885", "panda2": "-158913789845", "parrot": "-158913789915", "wolf": "-158913789911"}
nameSpace, systemName = serverApi.GetEngineNamespace(), serverApi.GetEngineSystemName()
# 监听PlayerAttackEntityEvent事件
self.ListenForEvent(nameSpace, systemName, "PlayerAttackEntityEvent", self, self.PlayerAttackEntityEvent)
# 玩家攻击生物时触发
def PlayerAttackEntityEvent(self, args):
# 由事件获取到的玩家攻击的生物ID
playerId = args['playerId']
entityId = args['victimId']
# 判断不同的NPC生物
if entityId == self.npcIdList["panda"]:
# 发送事件到客户端，打开UI，传输字典参数UIType用来判断玩家交互的生物以打开不同UI
self.NotifyToClient(playerId, "OpenGameInfoUI", {"UIType": "panda"})
elif entityId == self.npcIdList["panda2"]:
pass
elif entityId == self.npcIdList["parrot"]:
pass
elif entityId == self.npcIdList["wolf"]:
self.NotifyToClient(playerId, "OpenGameInfoUI", {"UIType": "wolf"})
在服务端脚本添加玩家攻击生物的事件并判断，如果是大厅的NPC，就传输事件到客户端创建UI。
# -*- coding: utf-8 -*-
import mod.client.extraClientApi as clientApi
ClientSystem = clientApi.GetClientSystemCls()
class FlumeRideClientSystem(ClientSystem):
def __init__(self, namespace, systemName):
ClientSystem.__init__(self, namespace, systemName)
print "Client初始化"
nameSpace, systemName = clientApi.GetEngineNamespace(), clientApi.GetEngineSystemName()
# 监听UiInitFinished事件
self.ListenForEvent(nameSpace, systemName, "UiInitFinished", self, self.UiInitFinished)
# 监听由FlumeRideServerSystem传过来的OpenGameInfoUI事件
self.ListenForEvent("FlumeRide", "FlumeRideServerSystem", "OpenGameInfoUI", self, self.OpenUI)
# 由FlumeRideServerSystem传过来的OpenGameInfoUI事件
# 当玩家与NPC交互时，判断交互的NPC类型并打开对应的UI
def OpenUI(self, args):
UIType = args['UIType']
if UIType == "panda":
clientApi.PushScreen("FlumeRide", "FlumeRideGameInfo")
elif UIType == "wolf":
clientApi.PushScreen("FlumeRide", "FlumeRideGameBook_1")
# UI初始化完成，将UI注册
def UiInitFinished(self, args):
clientApi.RegisterUI("FlumeRide", "FlumeRideGameInfo", "Script_FlumeRide.uiScript.FlumeRideInfoUI.FlumeRideInfoUI", "GameInfo.main")
clientApi.RegisterUI("FlumeRide", "FlumeRideGameBook_1", "Script_FlumeRide.uiScript.FlumeRideInfoUI.FlumeRideInfoUI", "GameBook.main")
clientApi.RegisterUI("FlumeRide", "FlumeRideGameBook_2", "Script_FlumeRide.uiScript.FlumeRideInfoUI.FlumeRideInfoUI", "GameBook_2.main")
现在，我们攻击大厅的生物，就可以打开UI界面了。
简单修改UI文件，将关闭按钮和引导手册的翻页按钮与FlumeRideInfoUI.py脚本文件中的某个函数绑定。
// ...
// UI文件
// 关闭按钮控件
"GameInfoButton@common.button" : {
// ···
// 绑定按钮按下时触发的函数 %ScreenNode脚本.函数名
"$pressed_button_name" : "%FlumeRideInfoUI.ClickedCloseButton",
// 需要删除
"button_mappings" : [],
// ...
},
// 翻页按钮同理
# -*- coding: utf-8 -*-
# ...
class FlumeRideInfoUI(ScreenNode):
def __init__(self, namespace, name, param):
ScreenNode.__init__(self, namespace, name, param)
# 绑定关闭按钮
@ViewBinder.binding(ViewBinder.BF_ButtonClickUp)
def ClickedCloseButton(self, args):
clientApi.PopScreen()
# 绑定翻页按钮
@ViewBinder.binding(ViewBinder.BF_ButtonClickUp)
def ClickedPageTurnButton(self, args):
GameBook1UI = clientApi.GetUI("FlumeRide", "FlumeRideGameBook_1")
GameBook2UI = clientApi.GetUI("FlumeRide", "FlumeRideGameBook_2")
if GameBook1UI:
clientApi.PopScreen()
clientApi.PushScreen("FlumeRide", "FlumeRideGameBook_2")
elif GameBook2UI:
clientApi.PopScreen()
clientApi.PushScreen("FlumeRide", "FlumeRideGameBook_1")
# 添加NPC对话
接下来为另一位NPC添加对话，简单描述一下地图背景和引导即可。
# -*- coding: utf-8 -*-
import mod.server.extraServerApi as serverApi
ServerSystem = serverApi.GetServerSystemCls()
commandComp = serverApi.GetEngineCompFactory().CreateCommand(serverApi.GetLevelId())

ServerSystem.__init__(self, namespace, systemName)
# ...
# 监听PlayerAttackEntityEvent事件
self.ListenForEvent(nameSpace, systemName, "PlayerAttackEntityEvent", self, self.PlayerAttackEntityEvent)
# 监听ClientLoadAddonsFinishServerEvent事件
self.ListenForEvent(nameSpace, systemName, "ClientLoadAddonsFinishServerEvent", self, self.DataInit)
# 玩家客户端加载完毕时触发，创建玩家数据
def DataInit(self, args):
# 由事件获取的玩家ID
playerId = args['playerId']
# 获取玩家的数据
playerDataComp = serverApi.GetEngineCompFactory().CreateExtraData(playerId)

# 玩家攻击生物时触发
def PlayerAttackEntityEvent(self, args):
def Panda2Guide():

commandComp.SetCommand("playsound random.orb " + playerName + " ~ ~ ~ 3 1 1")
# 根据玩家当前的对话阶段，触发不同的对话分支
if pandaMsg == 0:
# 使用指令接口生成对话
commandComp.SetCommand('tellraw ' + playerName + ' {"rawtext":[{"text":"熊猫 §a§l| §r§f《丛林激流》欢迎你！ §a(1/6)"}]}')
elif pandaMsg == 1:
commandComp.SetCommand('tellraw ' + playerName + ' {"rawtext":[{"text":"熊猫 §a§l| §r§f丛林的小动物们和人类一起建造了这里！ §a(2/6)"}]}')

# 到最后一条对话就重置数据并且return
playerDataComp.SetExtraData("pandaMsg", 0)
return
# 更新当前数据+1
pandaMsg += 1
playerDataComp.SetExtraData("pandaMsg", pandaMsg)
playerId = args['playerId']
entityId = args['victimId']
if entityId == self.npcIdList["panda"]:
# ...
elif entityId == self.npcIdList["panda2"]:
Panda2Guide()
elif entityId == self.npcIdList["parrot"]:
# ...
elif entityId == self.npcIdList["wolf"]:
# ...
使用【指令】实现这种对话效果，表现力较为薄弱，如果用UI代替会更好；但是实现起来会非常简单，如果对UI不熟练，可以使用这种方法。
# 控制镜头介绍内容
还剩最后一位NPC：鹦鹉；它将带领玩家观赏和讲解游戏中的场景和内容。

这种形式非常直观、生动；镜头可以是静态的，也可以制作成动态；镜头内的方块、生物等内容也可以通过动画加强表现力。非常适合用来设计引导！
# 其它
在一些可交互或者有玩法内容的实体、方块上添加标识，会更加直观：
