Basically has NPC’s greet you when they see you (and when it is possible to without overwriting another NPC’s greeting before you see it).

Cool.
Is it Rays or Magnitude based? or a bit of both?

Was done with raycasting initially; however I switched it to be based off of Region3’s.
Well it’s changed now; since Region3s don’t account for walls I made it so it is a combination of Region3 and Raycasting; if it raycasts into a transparent object, it will keep going to try and find the player.
I feel so welcomed.
Video doesn’t work?
EDIT: I should’ve refreshed I guess
That is very nice, what are you using it for?
Absolutely nothing. I made it so people in need of a utility like this could have it.

It isn’t set to “free”?

Didn’t realize that. Thanks.
It won’t let me edit the model to free. So I had to create a new one… New link: http://www.roblox.com/NPC-Greeter-item?id=247827904
Nice!
I’ve made something like this as well (shameless self promotion)
see 0:36

End game for me is similar to what you did in 0:36. I am planning on creating a full dialogue system
Why not do conical vision testing? that way it’s more realistic, the essence of a cone:
Dot product the lookvector and the unit vector between the NPC and player, it should be above the threshold of how ‘wide’ the cone it, 1 is a cone width of 0, 0.5 is a cone width of ~45 degrees, after the check to see if it’s within the cone sides, you do a magnitude check on the vector between the NPC and player to make sure it’s within range (adding a ‘base’ to the cone), then you raycast to the player from the NPC to make sure the player is actually visible, and not behind a wall, the raycast is last because it’s the most expensive of the checks
This method is how I move my units in my RTS, the cones I call collision cones, and units before moving in a direction do this cone check to see that the space they are moving to, they won’t collide with another unit, it’s a very cheap check, and yields pretty satisfying results, especially in your case, because human vision is conical

Because I’ve never heard of it. But thanks for the idea; I will work on making that the system when I decide to stop working on some of my other projects for this.
