Custom Action to stop the AI when the player is looking at it

[LoktarParticipant]

Hello everybody, I’ve been working with this powerful tool for like 2 weeks, and I’m absolutelly astonished with it, really, great job. But now comes my problem, I’m trying to create a custom action in which, the AI can only move to me when I’m not looking a it. Therefore, when I face it, it should stop moving and start just facing me, but I’m having problems by creating it, any idea? One of my problems is that I don’t know how to use the variable “Player” in the script, and I also don’t know how to detect if the AI is being looked by the player.

Thanks in advance 😉

Lots of ways to deal with it.
- you could just have the player object tell the AI when it is looking at it. Have a component on the player that grabs the AI rig, then sets a variable in AI working memory, like

rig.AI.WorkingMemory.SetItem("playerseesme", lookingAtAI);

- you could put an aspect on the player, mounted near his eyes but outside his collider. Then use a sensor on the AI to with a Line of Sight check.
- you could have the AI do a check on the forward angle of the player vs the angle from player to AI. If those are within some # of degrees, then set a variable to indicate “playerseesme” as above.

Thank you very much! It worked for me, I just put a sphere with entity behind the player and activated the line of sight of a visual sensor, then, if I’m facing the NPC, it won’t move because the Player is blocking the vision of the NPC. BUT, this solution has a problem, which is that when the terrain blocks the vision of the NPC it also stops. So now I need to tell to the AI’s Line of Sight to ignore the terrain, how could that be done?

Thanks again

Line of sight has a layer mask. You could use that to ignore the terrain. However, why does the AI stop when the player is looking at them? If it is intended to mimic the AI’s awareness of the player, then allowing the terrain to block the line of sight seems like a good thing. If it is simply a game mechanic, then I wouldn’t use sensors for it, but instead write some custom logic, as in the 3rd option.

Yes, I thought about using the Line of Sight Mask, but my problem is how to ignore just the terrain, because the options list of the line of sight mask is just:
·Nothing
·Everything
·Default
·TransparentFX
·Ignore Raycast
·Water

There’s no option to permit ignoring the terrain. Maybe creating a custom action to overide the Require Line of Sight?

You can add more layers through Unity and assign the terrain to its own layer. RAIN will pick up any new layers you define automatically.
