Unreal Engine 4 Tutorial - AI - Part 1 The Behaviour Tree 

Important: In the beginning when you add your skeletal mesh, be sure to rotate it so the character’s face is pointing the same direction as the blue arrow. The blue arrow represents the direction that is considered forward for the character, so when it moves it will rotate the character so that blue arrow is pointed toward where it’s going accordingly. The animation is triggered regardless along with moving the character, so if you don’t rotate the skeletal mesh it will have your character appearing to run sideways or backward and look unnatural. The tutorial creator does do this, but doesn’t call it out loud that he is doing it, so if you’re following more off what he is saying like I was this would be an easy mistake to make and then be confused why your character doesn’t seem to be moving correctly. Hope this helps avoid some frustration.

Underrated channel, this was by far one of the quickest tutorials that got to the point super quick. Thank you for taking your time to make these.

excellently put together with no fluff. I had my little cone moving around randomly withing 5 minutes and more importantly i understood why. I've looked through the next 5 videos and they all seem equally clear and concise. Thankyou very much

I really appreciate you taking the time to make this video. It's quick and ACTUALLY a tutorial rather than most tutorials that tell you what to do and not WHY you are doing it. Thank you!

Thanks for making this tutorial! This is the first video of yours I've seen so far, but it was the first result and exactly what I needed.

I gotta say, you're extremely good at getting information across. Straight to the point teaching style, friendly tone and no cringey fluff. Keep it up mate.

You deserve all the praise and more! Thank you for this excellent tutorial series.

This is one of the clearest tutorials I have ever seen! Good Job

So far its the best video tutorial on the topic out of maybe 4 or 5 that I've found online. Kudos and cheers, man!

just want to say thank you for your generosity and all of the incredible tutorials you make, they're super helpful and you do an incredible job on them. I've learned alot from you.

Ryan thank you. Mad respect. Just went through the AI course on Unreal online learning and toward the end I thought my brain was melting. Thanks for the concise tutorial.

I'm actually pleasantly surprised. Its hard to find clear and well done tutorials for UE. never looked at the AI but I'm entering a one man game jam so figured was about time ! Very useful ! Subbed :)

Great tutorial, I am brand new to AI in Unreal and this cleared up a lot of confusion, keep up the great work!

Thank you for creating this series! It's been super helpful, and has taught me a lot of new things about Unreal.

A very clear way to start understanding and creating AI, great tutorial! Thanks a lot, mate!

Really good tutorial series just what we were looking for, Good tutorials on AI Behaviour is hard to find, Thanks a lot MX-Games.

Thank you! Your tutorial is very clear and easy to follow! One of the best tutorials about Unreal Engine!

For the past two days, I've been re-watching this video and reviewing my work, trying to figure out how I could possibly have everything exactly the same, but still not have my AI working. It wasn't until I checked out the Unreal tutorial for Behavior Trees for this same movement that I noticed I had "FindRandomLocation," "MoveTo," and "Wait" all coming out of the Selector node instead of the sequence node lol. Definitely the biggest and longest brainfart I've had ever!

Finally got my dude running around. Big ups Ryan!! Just subbed because of this video!

This is a really well done and I enjoyed following this tutorial. Thanks Ryan.

Love your teaching style! Thanks Ry!

Just got to your channel for the first time, really enjoy your vids! keep doing the great stuff. it's very helpful :)

Legend! This is exactly what I needed. Clear explanation of Blackboards and Behaviour Trees

Thank You for sharing, and all the hard work that goes into content creation.

This is exactly what I needed to add to my arsenal of game development. I will be watching alot more!

This is explained far better than the official documentation, it's easier to follow, thank you! :)

All your tutorials are so clear and easy to follow even better than unreals own tutorial on this subject. Thanks!

Hi Ryan, I just want to thank you so much for these videos! They were really helpful when making my first game! I just made a devlog about it !

TOP video Mate, worked like a charm . good explanation and nice breakdown. No Filler :)

Such a great explanation, thank you for this video!

Thanks. Love your tutorials... keep up the good work.

A perfect absolute beginner tutorial, Thanks Ryan!

You must be reading my mind. I was JUST thinking "I hope he does an AI Tutorial." You're the man!

wow thank you for this tutorial! I've honestly been fighting to learn this over the past 8 hours. . . Within 30 minutes or so I now have basic npcs that run around mindlessly XD

Simple tutorial that gets the job done. Thank you very much.

amazing tutorial my friend the way you explain things is amazing and very clear and easy to understood :) Thanks my friend for this series

Thanks for this clear and simple tutorial! This makes AI easy for everybody!

Thankyou Ryan this was incredibly helpful 👍

Watched all the 12 videos. Thanks dude

Was trying to understand blackboards and ai, and this tutorial was very well explained. thx!

Well done, I'm needing this in my project now!

Thank-you for being so clear and precise

Thank you so much i was searching for this so long 😭😭

wow sir awesome teaching i love it, specially the way u explain about each part completely. thankyou so much sir.

Can't wait to go through and finish this tutorial. Always been interested in A.I in games and that was one of my first ideas for a game within Unreal, a more A.I driven game. So I'll be following this one closely. I have seen and worked on A.I in other games and engines and I kind of cringed at first at that initial Navmesh lol. That looked easy but incredibly sloppy with all the gaps and missing areas and just the general way it was laid out. Glad you said you could manipulate and fix it up lol.

looking forward learning from this, thanks!!

this channel is fantastic

Just wanted to say thanks, this video is extremely well explained.

Very Good, Clear Instruction! Thanks

amazing tutorial! thanks, waiting for the next one

This is incredible. Thank you, subbed immediately

Ryan... I just want to say that you cooked with this tutorial! Every tutorial always tells you to create a behavior tree where the AI starts wandering randomly...untill it sees the player, and all the tutorials to make it walk a certain path require a spline or a freaking patrol path etc... Your way literally makes it so all we need to do is replace the "Ai move to random point" to "Ai move to these specific points i want you to". Thanks a lot Ryan! Keep up on Cooking!

Unreal 4's nav mesh volume is so nice. I remember having to manually place individual nodes to make nav meshes in unreal 2 and 3, and I fully expected that to be the case here.

Thank you soooooo much for this video, it was exactly what i was looking for.

I REALLY LOVE YOUR VIDEOS BRO YOU HELPED MY FRIEND GRIND EVERY GAME ALL TO YOU THANKS BRO I LOVE YOU SO MUCH MAN!

Nice! Found useful and subbed. Very clear and well taught!

Sometimes RU-vid algorithm shows exactly what I need, great content thanks.

THANK YOU!!!! This is fantastic!

On UE5 the character will not animate following this tutorial unless you enable “Use acceleration for paths” under the character movement component of the AI BP

OMG, i learn how to make AI, thank you so much, i just start my journey as developer im subscribing

Thanks for your video, it was super clear and enjoyable :)

This is me just being dumb but for anyone it might help, when you create the vector key make sure in the behvaior tree the find random location is set to "target location" (vector key) and not self actor. Very good tutorial though, all these videos are super helpful!

the tutorial is just a wee bit fast paced but thats good, it makes people stay focused XD. great work man. Personal thanks for these videos

Good job, Ryan 👍

Really helpful stuff! :D

Thank you for your reply!

very in depth and helpful. thanks

awesome, super well explained ❣️

I love your tutorials xoxo

Really clear and well done tutorial ty man

here go again... It's my 4 time here making this project hahaha i love this series

Subbed mate, some great content! thanks a lot.

Good tutorial and I see the next video is "patrolling"- "sensing" ... Great ! thanks a lot

You're frigging awesome! Thank you very much for helping newbs learn.

Nice video, good explanation, step by step.

Great video. I learned a lot. Very clear and to the point. I just came from the official unreal engine AI tutorial. It was so poorly done I couldn’t watch it all (cringe) so this was a welcome sight.

Awesome! You are king! Subscribed :)

So I searched "NPC AI Unreal" and it brought me here. Thank you and have a great day.

Great stuff, thanks!

I did everything step by step, I'm not actually sure where I went wrong. The NPC didn't move when I hit play, it wouldn't move, I changed around the wait time and still didn't work. It was probably just something I did. Your tutorial is great though!

Great Video, I appreciate the help!

I like this guy, he gets on with it.

OG, This Ryan Laley guy???? Love him!!!!

This was so helpful, now i can experiment

Great tutorial. Thanks

Thanks. Great tutorial

Sir, you are legend, please have my respect.

Thank you Ryan :)

Thanks to you I finally can become a game developer 😇

Awesome!

Great video

Great tutorial

Well Explained thank you.

I hope you post a video with all the adobe cracks. As always, you are the best, the crack works great

Thanks, Great Tutorial.

Thank you. super program!

Nice job bro, realy work!!! tks!!!

Great series, learned a lot. However, I don't use Blueprints so I converted everything into C++ and started an AI series of my own based on what's here.

Very Nice Video, Thank you !!

you are a saviour ..i was stuck with behaviour tree..i want to build an adv combat system with sowds and all....now with the help of your tutorial i am feeling confident
