Particle.velocity 粒子速度

var velocity : Vector3

The velocity of the particle.

粒子的速度。

If there is a particle animator it will move the particle by the velocity every frame. The velocity is also used by the particle renderer if Stretch Particles is set to ParticleRenderMode.Stretch.

如果有一个particle animator(粒子发生器),它将在每一帧,以这个速度去移动粒子.如果Stretch Particles设置为PartcileRenderMode.Stretch,这个速度也会被particle renderer使用.
