ParticleSystem.sizeOverLifetime

설명

Script interface for the Particle System Size over Lifetime module.

This module controls the size of particles throughout their lifetime.

Particle System modules do not need to be reassigned back to the system; they are interfaces and not independent objects.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    void Start() {
        ParticleSystem ps = GetComponent<ParticleSystem>();
        var sz = ps.sizeOverLifetime;
        sz.enabled = true;

        AnimationCurve curve = new AnimationCurve();
        curve.AddKey(0.0f, 0.1f);
        curve.AddKey(0.75f, 1.0f);

        sz.size = new ParticleSystem.MinMaxCurve(1.5f, curve);
    }
}
