# 开始添加家具方块
除了农作物外，我们还需要继续制作家具，也是地图中重要的玩法之一；同样使用新自定义方块的方法，不过需要额外给不同的家具添加不同的功能。
# 学会设置方块的转向
当我们制作自定义方块的时候，如果方块模型的四个方向都是一样的，那方块在什么方向放置就不重要了；但如果是家具方块，如沙发，当玩家放下的时候，沙发的靠背朝前那就不太合适了，所以我们需要设置方块的转向，使每次放置都能保证方块的正面是适合的；
我们需要在方块中添加rotation的属性[0,1,2,3]对应四个方向：东南西北。然后添加四个组合，利用**"minecraft:rotation"**组件对应这四个方向的旋转角度，并且在放置方块的时候获取玩家朝向的角度，然后根据角度的不同修改方块的rotation属性，以rotation属性为条件添加组合，代码如下：

# 制作可以拼在一起的桌子
这里需要用到中国版自定义模型方块的写法，微软的1.16+自定义方块写法暂时还无法制作此功能；认识中国版自定义方块
给桌子方块添加基本的组件后，还需要用到**"netease:connection"**用来定义这个方块的拼接属性。
{
"format_version": "1.10.0",
"minecraft:block": {
"description": {
"identifier": "farm:connect_table",
"register_to_creative_menu": true,
"is_experimental": false
},
"components": {
"minecraft:block_light_absorption":{
"value": 0
},
"netease:render_layer": {
"value": "alpha"
},
"netease:solid": {
"value": false
},
"netease:connection": {
"blocks": ["farm:connect_table"]
}
}
}
}
然后打开桌子的模型文件，我们需要进行修改以实现桌子拼接时，部分模型块会消失，如桌子四周的挡板：
{
"cubes": [···],
"enable": "!query.is_connect(2)", //用表达式判断方块连接面的方向（连接面为北时启用这个部分的模型，因为前面加了！，所以为不启用这部分的模型）
// 0-down面，1-up面，2-north面，3-south面，4-west面，5-east面
"name": "n", //这个部分是桌子的背面挡板
"parent": "table",
"pivot": [···],
"rotation": [···]
},
使用上面的方法依次将东南西北四个方向的挡板都添加，点击编辑器的开发测试进入游戏，就可以从下方看到当桌子连接起来的时候，侧面的挡板消失了；
相比桌子的挡板，桌角并不是在某一侧，而是两个方向的夹角，所以只判断某一个方向的连接是不行的，需要两个方向都有桌子进行链接的时候才消失：
{
"cubes": [···],
"enable": "!query.is_connect(5) && !query.is_connect(3)", //桌子的东面和南面都有桌子时这个部分的模型不启用
// 0-down面，1-up面，2-north面，3-south面，4-west面，5-east面
"name": "east_south", //东面和南面夹角的桌角
"parent": "table",
"pivot": [···],
"rotation": [···]
},
把所有的桌脚都设置好后，进入游戏是这样的
# 制作带有开关的装饰方块
开关可以添加方块属性来进行判断，给台灯和电视都添加一个属性，值为[0,1]，对应开和关，然后利用MODSDK来切换方块属性：
{
"format_version": "1.16.100",

"register_to_creative_menu": true,

}
},
"permutations": [
{
"condition": "query.block_property('farm:open_light') == 1", //当属性open_light为1时
"components": {
"minecraft:block_light_emission": 1 //方块发光
}
}
],
"components": {···},
"events": {···}
}
}

床方块的放置和破坏逻辑写完后，我们还需要对其进行交互功能相关的逻辑，使玩家可以设置出生点并睡在床上跳过一段时间：

现在，我们已经有了一个较完整的现代床，在编辑器中点击开发测试进入到游戏中试一下：
# 制作可以回收道具的垃圾桶
这个功能只需要使用MODSDK即可做到，不需要对自定方块的组件进行复杂修改，代码如下：
class Main(ServerSystem):
def __init__(self, namespace, system_name):
ServerSystem.__init__(self, namespace, system_name)
self.ListenForEvent(namespace, system_name,
'ServerItemUseOnEvent', self, self.using_block) #监听ServerItemUseOnEvent事件
def using_block(self,args):
trash_can_list = ['farm:acacia_trash_can', 'farm:bigoak_trash_can', 'farm:birch_trash_can',
'farm:crimson_trash_can', 'farm:jungle_trash_can', 'farm:oak_trash_can',
'farm:spruce_trash_can', 'farm:warped_trash_can'] #所有的垃圾桶方块
playerid = args['entityId'] #事件中获取到的玩家id
blockname = args['blockName'] #事件中获取到的玩家交互方块的identifier
itemname = args['itemDict'] #事件中获取到的物品信息字典
item_comp = serverApi.GetEngineCompFactory().CreateItem(playerid) #创建CreateItem接口
if blockname in trash_can_list and itemname: #如果交互的方块在trash_can_list的列表中并且玩家手里有物品
args['ret'] = True #取消手中物品的使用（这个可以防止玩家手里的物品或方块被放置到地上从而无法清除）
carried_item = item_comp.GetPlayerItem(ItemPosType.CARRIED, 0, True) #获取玩家手中的物品信息
carried_item['count'] = 0 #将获取到的物品的数量设置为0
item_comp.SetPlayerAllItems({(ItemPosType.CARRIED, 0): carried_item}) #重新设置玩家手里的物品
在ServerSystem中只需要监听ServerItemUseOnEvent事件，并且添加一些简单的逻辑即可，不过这个事件建议在客户端同时监听并取消物品的使用，所以在ClientSystem中也需要一些代码：
class FarmClientSystem(ClientSystem):

# 制作可以榨取果汁的榨汁机
榨汁机工作需要用到我们收获的农作物：柠檬、菠菜、玉米，分别对应：柠檬汁、菠菜汁和玉米汁
给榨汁机添加多个属性分别代表 “判断榨汁机运行”、“榨玉米汁“、”榨柠檬汁“、”榨菠菜汁“；然后添加对应的组合，通过事件来进行调控，不过仅用自定义方块的组件内容无法制作全部的功能，我们还需要使用MODSDK；

上面的自定义方块内容，可以实现榨汁的过程（3秒）并且根据状态切换榨汁机的贴图，开始榨汁并且拿走果汁的功能就需要MODSDK来实现：

MODSDK和自定义方块组件的相互配合，完成这个榨汁机的全部功能，点击编辑器的开发测试进入到游戏中测试一下：
# 制作可以坐的方块
可以坐下的椅子和前面的现代床实现的方法差不多，并且没有那么的复杂，我们只需要传送玩家到椅子上并且播放坐下的动画即可，不过我们可以添加更多有意思的功能，比如在玩家坐下的时候可以每三秒回复玩家的半格血量：
class Main(ServerSystem):
def __init__(self, namespace, system_name):
ServerSystem.__init__(self, namespace, system_name)
# 判断坐下的变量
self.sit = 0
# 时间戳变量
self.interact_cooldown = {}
# 监听方块交互的事件
self.ListenForEvent(namespace, system_name,'ServerBlockUseEvent', self, self.using_item)
def using_item(self, event):
# 创建 计时器接口
timercomp = serverApi.GetEngineCompFactory().CreateGame(serverApi.GetLevelId())
# 创建使用指令的接口
commandcomp = serverApi.GetEngineCompFactory().CreateCommand(serverApi.GetLevelId())
# 创建使用指令的接口
commandcomp = serverApi.GetEngineCompFactory().CreateCommand(serverApi.GetLevelId())
# 事件获取的方块名称和坐标
block_name = event['blockName']
x = event['x']
y = event['y']
z = event['z']
# 所以椅子名称的列表
chair_list = ["farm:acacia_chair","farm:bigoak_chair","farm:birch_chair","farm:crimson_chair",
"farm:jungle_chair","farm:oak_chair","farm:spruce_chair","farm:warped_chair"]
# 如果交互的方块名称给列表内
if block_name in chair_list:
# 通过时间戳避免短时间内多次交互的情况
if player_id not in self.interact_cooldown:
self.interact_cooldown[player_id] = time.time()
# 如果sit为0（说明玩家未坐下）
if self.sit == 0:
# 使用指令播放玩家坐下的动画
commandcomp.SetCommand("playanimation @s sit_chair")
# 传送玩家到椅子上
commandcomp.SetCommand("tp @s {} {} {}".format(x,y-0.1,z))
# 设置玩家无法移动
playercomp.SetPlayerMovable(False)
# 创建消息接口并提醒玩家再次点击可以站起
msgcomp = serverApi.GetEngineCompFactory().CreateMsg(player_id)
msgcomp.NotifyOneMessage(player_id, "再次点击椅子以站起", "§f")
# 创建一个3秒的循环计时器
self.healtimer = timercomp.AddRepeatedTimer(3.0,self.player_heal,player_id)
# 修改坐下的变量为1
self.sit = 1
# 如果变量为1（此时玩家在坐着）
elif self.sit == 1:
# 设置玩家可以移动
playercomp.SetPlayerMovable(True)
# 取消循环的计时器
timercomp.CancelTimer(self.healtimer)
# 播放玩家普通
commandcomp.SetCommand("playanimation @s humanoid_base_pose")
# 修改坐下的变量为0
self.sit = 0
# 时间戳判断，与上方if逻辑一致
elif time.time() - self.interact_cooldown[player_id] > 0.5:
if self.sit == 0:
commandcomp.SetCommand("playanimation @s sit_chair")
commandcomp.SetCommand("tp @s {} {} {}".format(x,y-0.1,z))
playercomp.SetPlayerMovable(False)
msgcomp = serverApi.GetEngineCompFactory().CreateMsg(player_id)
msgcomp.NotifyOneMessage(player_id, "再次点击椅子以站起", "§f")
self.healtimer = timercomp.AddRepeatedTimer(3.0, self.player_heal, player_id)
self.sit = 1
elif self.sit == 1:
playercomp.SetPlayerMovable(True)
timercomp.CancelTimer(self.healtimer)
commandcomp.SetCommand("playanimation @s humanoid_base_pose")
self.sit = 0
self.interact_cooldown[player_id] = time.time()
# 计时器循环触发的函数
def player_heal(self,playerid):
# 获取玩家属性的接口
attcomp = serverApi.GetEngineCompFactory().CreateAttr(playerid)
# 获取玩家当前的血量
playerheal = attcomp.GetAttrValue(serverApi.GetMinecraftEnum().AttrType.HEALTH)
# 设置玩家当前的血量并+1
attcomp.SetAttrValue(serverApi.GetMinecraftEnum().AttrType.HEALTH, playerheal+1)
椅子的逻辑相对简单，我们点击编辑器的开发测试，进入到游戏中测试一下：
# 制作其它装饰方块
接下来我们继续填充装饰性的方块家具：马克杯、床头柜、水龙头、熊玩偶（纯装饰），马桶、沙发、浴缸（重复功能）。纯装饰的家具方块只需要添加属性使其可以跟随玩家视角旋转即可，一些重复功能的家具只需要利用上方的逻辑进行简单的修改即可。
马桶模仿椅子的逻辑，在判断方块的部分修改为马桶方块即可：
class Main(ServerSystem):
def __init__(self, namespace, system_name):
ServerSystem.__init__(self, namespace, system_name)
self.ListenForEvent(namespace, system_name,'ServerBlockUseEvent', self, self.using_item)
def using_item(self, event):
# 如果交互的方块是farm:close_stool（马桶）
if block_name == "farm:close_stool":
if player_id not in self.interact_cooldown:
self.interact_cooldown[player_id] = time.time()
if self.sit == 0:
commandcomp.SetCommand("tp @s {} {} {}".format(x, y - 0.1, z))
commandcomp.SetCommand("playanimation @s sit_chair")
playercomp.SetPlayerMovable(False)
msgcomp = serverApi.GetEngineCompFactory().CreateMsg(player_id)
msgcomp.NotifyOneMessage(player_id, "再次点击马桶以站起", "§f")
self.sit = 1
elif self.sit == 1:
playercomp.SetPlayerMovable(True)
commandcomp.SetCommand("playanimation @s humanoid_base_pose")
self.sit = 0
elif time.time() - self.interact_cooldown[player_id] > 0.5:
if self.sit == 0:
commandcomp.SetCommand("tp @s {} {} {}".format(x, y - 0.1, z))
commandcomp.SetCommand("playanimation @s sit_chair")
playercomp.SetPlayerMovable(False)
msgcomp = serverApi.GetEngineCompFactory().CreateMsg(player_id)
msgcomp.NotifyOneMessage(player_id, "再次点击马桶以站起", "§f")
self.sit = 1
elif self.sit == 1:
playercomp.SetPlayerMovable(True)
commandcomp.SetCommand("playanimation @s humanoid_base_pose")
self.sit = 0
self.interact_cooldown[player_id] = time.time()
沙发坐下的逻辑也与椅子、马桶相似，不过需要设置沙发在同行摆放的时候使其可以拼接，参照桌子的拼接方法，在沙发的两侧添加拼接：
{
"cubes": [···],
"enable": "!query.is_connect(4)",
"name": "left",
"parent": "sofa",
"pivot": [···],
"rotation": [···]
},
{
"cubes": [···],
"enable": "!query.is_connect(5)",
"name": "right",
"parent": "sofa",
"pivot": [···],
"rotation": [···]
}
浴缸的功能也是大同小异：放置和破坏同时对上半、下半部分生效，交互可以泡澡，每隔3秒增加玩家经验值。需要进行修改的也就只有方块的判断以及循环计时器的触发函数：
class Main(ServerSystem):
def __init__(self, namespace, system_name):
ServerSystem.__init__(self, namespace, system_name)
self.ListenForEvent(namespace, system_name,'ServerBlockUseEvent', self, self.using_item)
def using_item(self, event):
# 如果交互的方块是浴缸上半部分或下半部分
# 判断内的逻辑和现代床、椅子、沙发类似（传送玩家到方块位置、设置玩家无法移动、播放动画、添加循环触发的计时器）
if block_name == "farm:bathtub_head" or block_name == "farm:bathtub_tail":
# 循坏触发的计时器，每三秒触发一次player_exp函数
# ···
self.healtimer = timercomp.AddRepeatedTimer(3.0,self.player_exp,player_id,)
def player_exp(self,playerid):
# 创建玩家经验接口
expcomp = serverApi.GetEngineCompFactory().CreateExp(playerid)
# 给玩家添加10点经验
expcomp.AddPlayerExperience(10)
到此，所以的家具都已经制作完成，用它们来装饰地图吧：
