Detect when GameObject out of view [Solved]

[izzycoding]

Hi,

I have a scene where I need to be able to detect when an object is out of view.
For example, my character throws a bouncy ball, when the ball goes out of view I want the FSM to detect this and destroy its self.
Is there anything that can do this for me?
I was previously using a script in the OnBecameInvisible function to detect this.

Any ideas would be great.

Playmaker has a built in system event: BECAME INVISIBLE.

This is fired by the OnBecameInvisible event. So it's equivalent to what you were doing before.

Use this event in a global transition to activate a state and run actions when the GameObject becomes invisible.

Note: Unity uses ALL cameras to determine visibility, including the Scene View camera! Take this into account when testing!

Hi,

That is great, where do i find that? As I cant see it anywhere.
Currently I only have a single camera in my scene so that should be fine.

When you right click on a state to add a transition you can drill down to System Events.

See attached image.

Hi,

Great thanks, I knew it would be something simple.

:-) I was looking for an Action for this....lol

Hi,

I have replaced my playmaker stuff to use the system event.
I have only 1 camera in my scene but this event never triggers the BecameInvisible State.
Am I doing something wrong here?

Hi,

 Read the comments above, basically, I think you are confused with a unity bug, where the object also must be out of the "scene" view in editor,

I tested and works fine, so make sure that the object is actually not still visible on the scene, else it will not fire.

bye,

There's a little history on that here:
