- 类概要
  类 | 说明
  --- | ---
  ColorGenerate | 颜色生成器基础类基类，具体使用时需要使用它的子类，颜色rgba Base class for color generator, you need to use its subclass for specific usage, color rgba
  ConstantRotationOverLife | 旋转角度变化控制 Rotation angle change control
  CurveSizeOverLife | 大小根据曲线变化 Size varies according to the curve
  ParticleEmissionModule | 粒子系统分组,发射率，指定时间内发射多少个粒子，越多会越密集 但不会超过最大粒子数量 Particle system grouping, emission rate, specifies how many particles are emitted in a given time, the more the denser but will not exceed the maximum number of particles
  ParticleOverlay | 粒子效果，可以在地图上实现下雨、下雪和雾霾等天气效果，也可以通过开放的接口自定义 建议在`AMap.OnMapLoadedListener` 之后调用 Particle effects can simulate weather conditions like rain, snow, and haze on the map, and can also be customized through open APIs.
  ParticleOverlayOptions | 粒子效果初始化属性控制 建议在`AMap.OnMapLoadedListener` 之后调用 Particle effect initialization property control It is recommended to call after `AMap.OnMapLoadedListener`
  ParticleOverlayOptionsFactory | 粒子效果工厂类 建议在`AMap.OnMapLoadedListener` 之后调用 Particle Effect Factory Class Recommended to call after `AMap.OnMapLoadedListener`
  ParticleOverLifeModule | 生命周期内的一些属性变化 速度变化 角度变化等等 Some attribute changes during the lifecycle Speed changes Angle changes, etc.
  ParticleShapeModule | 发射器形状基类，具体使用时需要使用它的子类 Base class for emitter shapes, you need to use its subclasses in actual usage.
  RandomColorBetWeenTwoConstants | 颜色生成器 Color Generator
  RandomVelocityBetweenTwoConstants | 速度生长器 随机产生指定范围内的速度 Speed Generator Randomly generates speeds within the specified range
  RectParticleShape | 区域发射器，发起范围是某个区域 Area emitter, the initiation range is a specific area
  RotationOverLife | 旋转角度变化控制基类，具体使用时需要使用它的子类 Base class for rotation angle change control, which requires the use of its subclasses in practical applications
  SinglePointParticleShape | 指定位置发射 Launch at specified position
  SizeOverLife | 缩放比例变化控制基类，具体使用时需要使用它的子类 Base class for zoom level change control, concrete implementations require its subclasses.
  VelocityGenerate | 速度变化控制基类，具体使用时需要使用它的子类 Base class for speed variation control, concrete implementations require the use of its subclasses
