パラメーター

説明

Use this method to send a custom named event.

// The following example triggers the default visual effect play event once every second.
using UnityEngine;
using UnityEngine.VFX;
public class SendEventExample : MonoBehaviour
{
    public VisualEffect m_VisualEffect;
    private float m_Waiting = 1.0f;

    private void Update()
    {
        if (m_VisualEffect)
        {
            m_Waiting -= Time.deltaTime;
            if (m_Waiting < 0.0f)
            {
                m_Waiting = 1.0f;
                var eventAttribute = m_VisualEffect.CreateVFXEventAttribute();
                m_VisualEffect.SendEvent(VisualEffectAsset.PlayEventID, eventAttribute);
            }
        }
    }
}

// The following example triggers multiple events during the same frame every second.
using UnityEngine;
using UnityEngine.VFX;
