Enemy AI Don't Move When You Look At Them | You Can't See Through Walls - Unreal Engine Tutorial

Hey guys, in today's video, I'm going to be showing you how to make it so when the player looks at your AI, they will not be able to move. This also works with obstacles and walls, so the player cannot see through them.

Excellent. Someone can recreate the weeping angels now!

What about glass?

[arkgamer]

others: when do I use this? I mean the enemy should move when they are viewed

SCP devs: I`ll take your entire stock

[dr.pgopakumar]

I've been waiting all my life for this tutorial....Thankx Matt :)

[nikgiak]

Hello Matt, ty for another great tutorial.
I'm happy to see you doing more AI tutorials! Awesome!

[RelytX]

Awesome! I love you how you took the time to explain how and why very detailed and extremely informative!

[MeowMasterZombo]

For noobs like me: the tutorial works, but will also interact with everything in sight. On the cone collision at the custom setting, I set the object responses (outside of pawn) to ignore, then it worked without issues.

[MrGooshy]

Not sure if you've already done this, but it would help out a lot if you made a video on picking up items as well as it showing on screen. Like picking up a flashlight and being able to use it. You're literally the best UE4 teacher on here 👍

[PatrickTheDM]

Very cool. I'm planning to use the overlap part of this to make sure the character is facing an object that has an interactive animation. 👍

[hdelorian]

It works very well. The only issue I've run into is when the enemy comes into view, it....kind of glitch moves stationary out of view whenever I move my camera towards it.

[Bleeped]

Thanks for the tutorial mate. I just have one issue, the AI doesn't stop moving when there is another AI nearby. For some reason, my pawn sensing component doesn't detect multiple AI at once so how would I fix that?

[phillips]

Great video! Could you please make an AI based off a behavior tree with chase music and melee attack?

[fleurbird]

I should really start using BP interface.
Nice tut as always

[SevenYearsGoodLuck]

This is going to scare the crap out of people in horror videogames.

[azngf]

Speaking of Five Nights At Freddie's, there's no tutorials about how to do that style of jumpscare on YouTube. Would be quite interesting to see!

[jasonyeo]

Thanks for the video...but I'm stuck again because the cone overlaps with collectables items from a distance, the player will collect them without being near to the items. How can I fix the collision problem? I want to make the AI stop at the same time I don't want the player to collect the items by just looking at them.

[taintedpain]

Can you make the Ai follow the players footprints 2 locate the player

[fleurbird]

If you enabled the right snapping mode in blender. You can grab the object and snap it to the center.
This is easier and infinitely more precise.
But off course this is not a Blender tutorial 😉

[myeyesdontbreathe]

Ine thing i found which can basically make this alot simpler is the "WasActorRecentlyRendered" node. Just stick it in a branch and there you go!

[theoneoverseeraotoariseoft]

quick question to fire out in hope of response: this system oddly interacts with objects simulating physics in my project. The question really being; is there a way to stop it from knocking around these objects, if so please explain to me how I might be able to fix this issue.

[israeloconnor]

could you make a save system that works for games with no player character? (im making a clicker game that is coded in the gui and i cant figure out how to cast to it)
