How to use isVisible or OnBecameInvisible() to detect player offscreen
This is probably a dumb question but I can't figure it out. I need to detect if the player is offscreen and then call some events. Here is some code I was testing:
public class GameHandler : MonoBehaviour
{
public Renderer playerRenderer;
private void Update()
{
if (playerRenderer.isVisible)
{
print("Player is onscreen");
}
if (!playerRenderer.isVisible)
{
print("Player is offscreen");
}
}
}
When I run this I get "Player is onscreen" all the time, even when the player is offscreen. I never get "Player is offscreen" under any circumstance. I also tried this code instead, on the player renderer.
public class PlayerOffscreen : MonoBehaviour
{
public void OnBecameVisible()
{
print("Player is onscreen");
}
public void OnBecameInvisible()
{
print("Player is offscreen");
}
}
When I run this I get "Player is onscreen" once at game start, regardless of whether the player is actually onscreen. I don't get any other messages until I stop the game and then I get "Player is offscreen" once.
I have heard that the editor camera can interfere with these functions so in both cases I have it turned completely away from the scene. It doesn't seem to make a difference.
What am I doing wrong?
I'm not sure what exactly you mean by on screen and off screen but check this and see if it's what you want.
private void OnApplicationPause(bool pause)
{
if (pause)
{
OnBecameInvisible();
}
else
{
OnBecameVisible();
}
}
private void OnBecameVisible()
{
print("Player is onscreen");
}
private void OnBecameInvisible()
{
print("Player is offscreen");
}
