Particle.energy 粒子能量

var energy : float

The energy of the particle.

粒子的能量。

This is the time in seconds for how long this particle will remain alive. When the energy drops below zero the the Particle will be killed.

粒子的生存周期.当能量低于0时,他就会消失.

The energy is also used for UV animation:
If energy equals Particle.startEnergy the first tile will be used.
If energy equals 0 the last tile will be used.

能量也被用于UV动画.
如果能量等于Particle.starEnergy,第一个片段将被使用.
如果能量等于0，最后一个片段将被使用.
