Particle system position type.

#### Definition

`typedef NS_ENUM(NSUInteger, CCParticleSystemPositionType ) {
CCParticleSystemPositionTypeFree,
CCParticleSystemPositionTypeRelative,
CCParticleSystemPositionTypeGrouped,
};`

#### Constants

`CCParticleSystemPositionTypeFree`

  Living particles are attached to the world and are unaffected by emitter repositioning.

  Declared In `CCParticleSystemBase.h`.

`CCParticleSystemPositionTypeRelative`

  Living particles are attached to the world but will follow the emitter repositioning. Use case: Attach an emitter to an sprite, and you want that the emitter follows the sprite.

  Declared In `CCParticleSystemBase.h`.

`CCParticleSystemPositionTypeGrouped`

  Living particles are attached to the emitter and are translated along with it.

  Declared In `CCParticleSystemBase.h`.
