説明

Choose how the system generates the particle trails.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { private ParticleSystem ps; public bool ribbonMode = false;

void Start() { ps = GetComponent<ParticleSystem>();

var main = ps.main; main.startColor = new ParticleSystem.MinMaxGradient(Color.red, Color.yellow); main.startSize = 0.1f; main.startLifetime = 2.5f; main.gravityModifierMultiplier = 0.2f;

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.mode = ribbonMode ? ParticleSystemTrailMode.Ribbon : ParticleSystemTrailMode.PerParticle; }

void OnGUI() { ribbonMode = GUI.Toggle(new Rect(25, 25, 200, 30), ribbonMode, "Ribbon mode"); } }
