上图是spark源码中发射器emitter的框架
我们开始逐个分析:
1.normal
An emitter that emits particles following a Zone normals.
The Zone used to derive the direction of emission can either be the emitter‘s zone or another zone that can be set with setNormalZone(Zone*).
If the normal zone is NULL the emitter‘s zone is used.
这里大家看到zone,如果有不理解,我在本文最后有大致介绍,这里就当成一个固定区域就行了
这就各种形状的区域。
