ParticleSystem.BurstConstructor

切换到手册
public ParticleSystem.Burst (float _time, short _count);
public ParticleSystem.Burst (float _time, short _minCount, short _maxCount);
public ParticleSystem.Burst (float _time, short _minCount, short _maxCount, int _cycleCount, float _repeatInterval);
public ParticleSystem.Burst (float _time, ParticleSystem.MinMaxCurve _count);
public ParticleSystem.Burst (float _time, ParticleSystem.MinMaxCurve _count, int _cycleCount, float _repeatInterval);

参数

_time 要发射爆发的时间。
_minCount 要发射的最小粒子数。
_maxCount 要发射的最大粒子数。
_count 要发射的粒子数。
_cycleCount 指定系统应播放爆发的次数。如果设置为 0,则无限制地播放。
_repeatInterval 重复爆发的频率(以秒为单位)。

描述

使用时间和计数构造新的爆发。
