MonoBehaviour.OnWillRenderObject()

Description

OnWillRenderObject is called for each camera if the object is visible and not a UI element.

Эта функция вызывается только если Behaviour включен.

The function is called during the culling process just before rendering each culled object. For usage in a proper context, see the script Water.cs in Assets->Import Package->Effects

Note that Camera.current will be set to the camera that will render the object.

Note: This has no effect when called from a UI element.

using UnityEngine;
using System.Collections;

public class ExampleScript : MonoBehaviour
{
    public Renderer rend;

    private float timePass = 0.0f;

    void Start()
    {
        rend = GetComponent<Renderer>();
    }

    void OnWillRenderObject()
    {
        timePass += Time.deltaTime;

        if (timePass > 1.0f)
        {
            timePass = 0.0f;
            print(gameObject.name + " is being rendered by " + Camera.current.name + " at " + Time.time);
        }
    }
}

This is called multiple times per frame.
