public ParticleSystem.SizeBySpeedModule sizeBySpeed;


Script interface for the SizeBySpeedModule of a Particle System.

This module controls the size of particles based on their speeds.

Particle System modules do not need to be reassigned back to the system; they are interfaces and not independent objects.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { void Start() { ParticleSystem ps = GetComponent<ParticleSystem>(); var ss = ps.sizeBySpeed; ss.enabled = true; ss.range = new Vector2(0.0f, 2.0f);

AnimationCurve curve = new AnimationCurve(); curve.AddKey(0.0f, 0.1f); curve.AddKey(0.75f, 1.0f); ss.size = new ParticleSystem.MinMaxCurve(10.0f, curve); } }
