MinMaxGradient

struct in UnityEngine

マニュアルに切り替える

説明

MinMaxGradient contains two Gradients, and returns a Color based on ParticleSystem.MinMaxGradient.mode. Depending on the mode, the Color returned may be randomized. Gradients are edited via the ParticleSystem Inspector once a ParticleSystemGradientMode requiring them has been selected. Some modes do not require gradients, only colors.
