有三个场景地图内有门, 角色进入门后即移动到下一个地图.
门可以返回.
地图切换的思路:
– 做一个空的地图引用, 作当前地图, 每一帧都只把当前地图交给描画部分描画和角色部分判定位置.
– 初始化时先把第一个地图读进当前地图的空引用.
– 发生场景切换时, 把新地图的应用传递给当前地图的应用.
触发切换的思路:
– 给地图类附加一个热点容器, 热点也是障碍物, 但内包时不做碰撞判定, 仅告知外部某一点内包在哪一个热点(即门).
– 给每一个障碍物类附加一个标识码, 当障碍物做热点处理时, 角色进入区域时告知标识码给角色.
– 角色移动后告知标识码给键盘事件, 在键盘事件内决定要做的动作(即切换地图).
[W|S|A|D]:移动角色
[Q]:退出程序
在2.0内制作, 用3.0以上运行可能会报错:
