Set whether the particle size acts as a multiplier on top of the trail lifetime.
Useful for making larger particles have longer trails.
using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { private ParticleSystem ps; public bool sizeAffectsLifetime = true;
void Start() { ps = GetComponent<ParticleSystem>();
var main = ps.main; main.startColor = new ParticleSystem.MinMaxGradient(Color.red, Color.yellow); main.startSize = new ParticleSystem.MinMaxCurve(0.01f, 1.0f); main.startLifetime = 1.5f;
var trails = ps.trails; trails.enabled = true;
var psr = GetComponent<ParticleSystemRenderer>(); psr.trailMaterial = new Material(Shader.Find("Sprites/Default")); }
void Update() { var trails = ps.trails; trails.sizeAffectsLifetime = sizeAffectsLifetime; }
void OnGUI() { sizeAffectsLifetime = GUI.Toggle(new Rect(25, 25, 200, 30), sizeAffectsLifetime, "Size affects lifetime"); } }
