Description

最小值-最大值曲线的脚本接口。

MinMaxCurve 描述的函数采用介于最小值与最大值限制之间的值并基于 ParticleSystem.MinMaxCurve.mode 返回值。根据模式,返回值是随机的。 对于需要曲线的模式,返回值取决于在 ParticleSystem Inspector 中设计的一条或两条曲线,这些曲线可以计算得到介于 -n 与 n 之间的单个值,其中 n 是也在 Inspector 中设置的常量。请参阅 ParticleSystemCurveMode 以了解更多信息。

Variables

constant设置常量值。
constantMax为上限设置常量。
constantMin为下限设置常量。
curve设置曲线。
curveMax为上限设置曲线。
curveMin为下限设置曲线。
curveMultiplier设置要应用于曲线的乘数。
mode设置模式,最小值-最大值曲线将使用该模式计算值。

Constructors

ParticleSystem.MinMaxCurve用于整个曲线的单个常量值。
