using System.Collections;

[RequireComponent(typeof(ParticleSystem))] public class ExampleClass : MonoBehaviour { void Start() { ParticleSystem ps = GetComponent<ParticleSystem>(); var customData = ps.customData; customData.enabled = true;

AnimationCurve curve = new AnimationCurve(); curve.AddKey(0.0f, 0.0f); curve.AddKey(1.0f, 1.0f);

customData.SetMode(ParticleSystemCustomData.Custom1, ParticleSystemCustomDataMode.Vector); customData.SetVectorComponentCount(ParticleSystemCustomData.Custom1, 1); customData.SetVector(ParticleSystemCustomData.Custom1, 0, new ParticleSystem.MinMaxCurve(1.0f, curve)); } }
