本文主要是介绍Unity 家居摆放系统设计 (一)，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
之前看到明日方舟的宿舍挺有趣的，可以摆放大小不一的家具在一个矩形体的六面墙上。之前写了没时间弄博客现在做下记录。
本次设计点：
1、层级结构为，根节点下面有六面墙壁，每面墙在代码里会进行大小的缩放，所以这里为保持每面墙内的物体能够按照实际大小摆放，多加了一个反向缩放的原始节点层，在里面就是格子层和家具层
顶部墙面
底部墙面
前部墙面
垂直的面加了四条线以显示边界
后部墙面
2、房间大小、格子大小、家具大小全部动态设置，效果如下面图所示：
格子正方形，房间正方形，家具长方形
格子长方形，房间正方形，家具正方形
房间长方形，格子正方形，家具正方形
3、目前一个面一个碰撞体共6个碰撞体，为了每一面都可以求出局部坐标进而求出每个格子的坐标再换算出行列；重合检测有房间内的所有家具的边界检测，和所有家具之间的重合检测。目前没时间弄，边界检查只需判断家具靠墙的一面的长宽共4个点是否越出墙的长宽即可；至于家具之前的重合检测，初步考虑用算法，将房间分割成X*Y*Z个小六面体，每个小六面体都存储有投影到六面墙上时每一面墙上对应所有已被其他家具占用的格子，这样每次家具的移动都对n个被波及到的小六面体进行数据增删以及检测重合。或者考虑用八叉树处理优化下。具体有空再试试
4、未精简优化代码：
控制器：
module("room.RoomController", Class.impl(Controller))--构造函数
function ctor(self, cusMgr)super.ctor(self, cusMgr)
end--析构函数
function dtor(self)
end-- Override 重新登录
function reLogin(self)super.reLogin(self)
end--游戏开始的回调
function gameStartCallBack(self)
end--模块间事件监听
function listNotification(self)GameDispatcher:addEventListener(room.RoomManager.OPEN_ROOM_PANEL, self.__onOpenRoomPanelHandler, self)
end--注册server发来的数据
function registerMsgHandler(self)return {}
endfunction __onOpenRoomPanelHandler(self, args)self:__addFrameHandler()self:__openRoomScene()room.RoomManager:setMainUICameraVisible(false)if(not self.mRoomPanel)thenself.mRoomPanel = room.RoomPanel.new()self.mRoomPanel:addEventListener(View.EVENT_VIEW_DESTROY, self.onDestroyRoomPanelHandler,self)endself.mRoomPanel:open()
