实现原理:雨和雪的实现基本类似,天空中飘的雨和雪,地上的水花和雪花,增加一个下落速度和风速,就形成了天气了。
天气雪实现步骤:
1、预生成Mesh:随机生成多个空中飘落的雪网格和地面上的雪花网格。
2、预生成雪shader和雪花shader,雪shader支持雪的显示,雪花shader支持序列帧动画显示。
3、新建一个雪相机,该相机只渲染Water层,所有和雪有关的都挂到Water层。
4、创建雪模板gameobj,模板包括MeshRenderer、雪shader创建的材质Material、MeshFilter。
5、创建雪花模板gameobj,模板包括MeshRenderer、雪花shader创建的材质Material、MeshFilter。
6、根据模板创建雪群:按高度分为上中下三层,随着时间下落到一定高度最下层会放到最上层,如此循环。
7、帧循环更新:雪相机跟随主相机偏移(xz变y不变),雪根据下落速度变化高度,根据风速变化水平位移,风速随时间变化,雪花随时间变化显示不同的动画关键帧。
8、雪从最高点重新下落会随机更新MeshFilter中mesh网格。
9、关闭雪的时候不是一下全部消失,得有个缓冲过程,都下落到最低点的时候消失。
