Homework8-简单粒子系统

简单粒子制作

按参考资源要求，制作一个粒子系统

参考资料
Particle System的配置如下：

设置子Particle System的主要设置如下：

制作完成粒子的如下：

使用 3.3 节介绍，用代码控制使之在不同场景下效果不一样

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class ParticleSea : MonoBehaviour
{
    public ParticleSystem particle;
    private ParticleSystem.Particle[] particlesArray;
    public int seaResolution = 50;
    public float spacing = 0.5f;
    public float noiseScale = 0.2f;
    public float heightScale = 3f;
    private float perlinNoiseAnimX = 0.01f;
    private float perlinNoiseAnimY = 0.01f;
    void Start()
    {
        particlesArray = new ParticleSystem.Particle[seaResolution * seaResolution];
        particle.maxParticles = seaResolution * seaResolution;
        particle.Emit(seaResolution * seaResolution);
        particle.GetParticles(particlesArray);
    }
    void Update()
    {
        for (int i = 0; i < seaResolution; i++)
        {
            for (int j = 0; j < seaResolution; j++)
            {
                float zPos = Mathf.PerlinNoise(i * noiseScale + perlinNoiseAnimX, j * noiseScale + perlinNoiseAnimY) * heightScale;
                particlesArray[i * seaResolution + j].position = new Vector3(i * spacing, zPos, j * spacing);
            }
        }

        perlinNoiseAnimX += 0.01f;
        perlinNoiseAnimY += 0.01f;

        particle.SetParticles(particlesArray, particlesArray.Length);
    }
}

效果如下：
