ParticleSystem.externalForces

설명

Script interface for the ExternalForcesModule of a Particle System.

This module enables ParticleSystemForceField and WindZone components to affect the Particle System.

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;

[RequireComponent(typeof(ParticleSystem))]
public class ExampleClass : MonoBehaviour {
    void Start() {
        ParticleSystem ps = GetComponent<ParticleSystem>();
        var ex = ps.externalForces;
        ex.enabled = true;
        ex.multiplier = 0.1f;
    }
}
