ParticleSystem.NoiseModule.positionAmount

설명

How much the noise affects the particle positions.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    private ParticleSystem ps;
    public float hSliderValuePositionAmount = 1.0f;
    public float hSliderValueRotationAmount = 0.0f;
    public float hSliderValueSizeAmount = 0.0f;

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

        var noise = ps.noise;
        noise.enabled = true;

        var psr = GetComponent<ParticleSystemRenderer>();
        psr.material = new Material(Shader.Find("Sprites/Default"));    // this material renders a square billboard, so we can see the rotation
    }

    void Update()
    {
        var noise = ps.noise;
        noise.enabled = enabled;
        noise.positionAmount = hSliderValuePositionAmount;
        noise.rotationAmount = hSliderValueRotationAmount;
        noise.sizeAmount = hSliderValueSizeAmount;
    }
