Title: How do you trigger a No Hit Event for when raycast hits nothing? [solved]
Post by: createasaurus on September 24, 2014, 12:13:41 PM

I am making an enemy player AI.  I want him to stop when he reaches a cliff that is too high.

I put a raycast with -1 on Y (pointing down) and set the distance to 1.5.  My hope was that the raycast would constantly hit the terrain mesh.  Then when the terrain mesh dropped out by more than 1.5... BAM - it would trigger a No Hit Event for full stop.  Unfortunately, I do not see a No Hit Event in the raycast action.  Is there a way to do this, or is there a different approach to this problem that you could recommend?

Thank you very much,
Createasaurus

Hmmm... maybe if I look into the Store Hit Distance.... and check if the distance is greater then X...  I going to be experimenting along these lines next.

or you could also store collider info and do a check on that

I didn't make a thread for it, never got around to polishing and finishing it but it should work.

@Lane, there is a Raycast 2 custom action???!!!  NICE!!!
I have it loaded and will be testing out the No Hit Event.

@terri, Thanks I'll check this out if the custom action is a no go.

Nice!  The Raycast 2 action's additional functionality has what I need.  I have a RayCast 2 pointing down at a 1.5 length.  It has a No Hit Event which fires off if there is no floor underneath at a distance of 1.5 or greater.  No more enemies blindly walking off cliffs!  Thank you.
