ParticleSystemRenderer.maxParticleSize

説明

パーティクルの大きさを制限する

Particles can become very heavy on fillrate. Use this setting to make sure they don't use too much performance when up close to the viewer.

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(ParticleSystem))]
public class ExampleClass : MonoBehaviour {

    private ParticleSystem ps;
    private ParticleSystemRenderer psr;
    public float minSize = 0.0f;
    public float maxSize = 1.0f;

    void Start() {

        ps = GetComponent<ParticleSystem>();
        psr = GetComponent<ParticleSystemRenderer>();

        var main = ps.main;
        main.startSize = new ParticleSystem.MinMaxCurve(0.1f, 5.0f);
    }

    void Update() {
        psr.minParticleSize = minSize;
        psr.maxParticleSize = maxSize;
    }

    void OnGUI() {
        GUI.Label(new Rect(25, 40, 200, 30), "Minimum Screen Space Size");
        GUI.Label(new Rect(25, 80, 200, 30), "Maximum Screen Space Size");

        minSize = GUI.HorizontalSlider(new Rect(245, 45, 100, 30), minSize, 0.0f, 1.0f);
        maxSize = GUI.HorizontalSlider(new Rect(245, 85, 100, 30), maxSize, 0.0f, 1.0f);
    }
