思路:
screen分为普通和复杂两种,普通的功能大部分是页面跳转以及简单的crud数据,复杂的单独弄出来
跳转普通的screen,直接根据配置文件调整设置
<layouts> <loyout screenId="0" bg="bg_start" name="start" defaultWinId="" bgm="" remark=""> </loyout> <loyout screenId="1" bg="bg_main" name="main" defaultWinId="0" bgm="" remark=""> <window id="0" scale="1.0" bg="" x="0" y="0" w="0" h="0" float="center" > <buttons > <button x="50" y="30" w="0" h="0" imgUpName="mbtn_empire" imgDownName="mbtn_empire" functionId="0" font="" remark="帝国"></button> <button x="300" y="30" w="0" h="0" imgUpName="mbtn_conquest" imgDownName="mbtn_conquest" functionId="1" font="" remark="征服"></button> <button x="550" y="30" w="0" h="0" imgUpName="mbtn_commder" imgDownName="mbtn_commder" functionId="2" font="" remark="指挥官"></button> <button x="800" y="30" w="0" h="0" imgUpName="mbtn_option" imgDownName="mbtn_option" functionId="3" font="" remark="设置"></button> <button x="300" y="120" w="0" h="0" imgUpName="mbtn_map" imgDownName="mbtn_map" functionId="4" font="" remark="地图"></button> </buttons> </window> </loyout> </layouts>

构想中首先根据screenId获得其布局背景图,布局默认stage编号,背景音乐等信息,
然后一个window代表一个stage,buttons下加载其按钮配置
随后还设想加入Lable(文本标签)和Image(图片标签),并且x,y,w,h等都会变为百分比计算距离,根据float来确定位置(靠左,靠右,居中),根据bgm切换音乐
实现多窗口(多stage),动态加载内容等功能
此篇将随着后续对ui的完善持续更新
6.22更新:
所有坐标按百分比读取,绘制点为图片中心点,如果超边界,会顶边而不超出去
