OnBecameVisible does not work
I am trying to optimize CPU usage for the game so I stop rendering when the object is out and render it again when it come back to screen. But the second part I can't get it to work. The Cat disappeared but never appeared again even I could see it in the Hierachy in editor.
The code is followed:
using UnityEngine;
public class CatUpdater : MonoBehaviour {
private CatController catController;
void Start () {
catController = transform.parent.GetComponent<CatController>();
}
void UpdateTargetPosition()
{
catController.UpdateTargetPosition();
}
void GrantCatTheSweetReleaseOfDeath()
{
Destroy( transform.parent.gameObject );
}
void OnBecameInvisible()
{
renderer.enabled = false;
catController.OnBecameInvisible();
}
void OnBecameVisible()
{
if (!renderer.enabled)
{
Debug.Log("Cat is visible " +gameObject.name);
renderer.enabled = true;
}
}
}
void OnBecameVisible()
{
if (!renderer.enabled)
{
If you can see it, make it visible?
Play around with Renderer.isVisible
@meat5000 If the camera see it and rendering was disabled then enable it. So your logic is correct. I also played around with renderer.isVisible but it also does not work.
void Update()
{
if (gameObject.renderer.isVisible && !gameObject.renderer.enabled)
{
Debug.Log("Cat is visible " +gameObject.name);
renderer.enabled = true;
}
}
The debug log never fired up.
Playing with the function around, I finally understood a bit more. OnBecameVisible only determine if the game object is visible ONCE. Which mean it only run the first time any camera see the object; the next time any camera sees game object, nothing will happen. So I have to repeat the function consistently to make it work in runtime.
VERY IMPORTANT -> If your Scene is visible while you're running your game, if the object / sprite is visible in your Scene window, the OnBecameVisible() will get called even if it is not visible in Game window.
