- This is episode 42 of my unreal engine 4 beginner tutorial series, in today's episode we show you a quick introduction to creating AI inside of the engine, having said that you'll be able to create an additional character that can sense the pawn and follow it accordingly!
This is all done through blueprints, I explain how to create an AI class, navigation elements, the components required and show you how to set up the required scripts to get it moving!

I've been looking at hours of tutorials that teaches the AI equivalent of how to build a car before showing you how to drive. Then I found this gem and I have a character following me after 5 minutes. Thank you.
Just a quick update, the next AI video is uploaded and will be available from tomorrow morning... Stay tuned!
+Virtus Education This is great but.... unfortunately it replicates the many Vision sense tutorials already in the wild.
Could you please, abso-totally-pretty-please, create a basic Hearing/Emission tutorial for beginners. Because it simply doesn't exist.
Please and thank you.
Keep up the good work.
+Ash _ And i cant find how to make hearing system for my AI.
Virtus Learning Hub / Creative Tutorials How could I do this on third person?
my unreal engine keeps crashing
Just an FYI for those wanting to adjust the peripheral vision to be more accurate, the depth perception angle for a human covers 114 degrees (horizontally) and 70 degrees for peripheral, so setting it to 70 gives a good representation of real life.
i usually set FOV in games i play to around 85 so it feels more natural and not the"tunnel vision" that most of the devs think is right, i guess he made no exception to that statement :D
also the 70 degrees peripheral is that for each eye or ? i can sense movement up to about 170 degree's so even if added up it still not right.
@@witgangyounotube287 I know this is late but he said 114 horizontally and 70 peripheral. which totals at 184 degrees total vision
as in 114 of straight actual vision and then 35 degrees of peripheral per side
if that is not what he meant then I'm lost cause 70 is way too small
sorry to be so offtopic but does anybody know a tool to get back into an Instagram account?
I was stupid forgot my account password. I love any tips you can offer me.
one of the few good tutorials I can find that explains things well, thank you !
Also I must mention you guys are The BEST!!. Best tutorials around! Thank you!
I love how straight forward you are with teaching.
So short so simple and so effective, best tutorial so far for this lesson.
Best tutorials on TH-cam! Keep up the good work!
"Duplicate your third-person chracter"
Me, making an FPS: well shit
i did a first person one as well just duplicate the Fp chr put a model in and do the coding he did it worked for me
Cool
oh no
@@ThatMrFlixy can anyone translate that into ue4 noob for me please?
i actually had to drop the fpp idea..xD
BEST tutorial for UE4 that I have found. Earlier videos had weird background noise, but great job.year old but still works :D
Thanks, man! You didn't rush and it was easy to keep up with the tutorial.
As someone who's from a hardcore Unity background - your tutorials are great!
Very good! A perfect tutorial for those who are just starting to learn. You gained another subscriber!
PS- Keep teaching in a very procedural way, so everyone learns without too many difficulties...unlike the other videos.
As always another great video. Keep up the good work!
Amazing tutorial work super well. Thank you very much! Im a begginer and this helped a LOT.
Thank you so much! I've been needing something like this.
Such an impressive tutorial , Thank you very much sir.
Very well explained! Thank you for your time.
I was watching Matt's intro to Unreal and I have found his avoidance of casts great. It also served as a good introduction to Blueprint Interfaces. Avoid casts, if possible people
Thank you, This will Most certainly come in handy!
this is amazing
thanks for that genius tutorial
Such a helpful video thank you for putting it out.
Very helpful Video! Thank u!
This is such a great short tutorial.
I have been looking for this and it's finally here! Thank you so much, Virtus! :)
+T. L. Bainter I'm glad you found it, let me know if there's anything else you'd like to see!
+Virtus Education Hm, well a tutorial on lifting/carrying/placing objects would be awesome! I'm having trouble finding a video tutorial on that one. Kind of like the Zelda-Style interactions? That would be splendid!
+T. L. Bainter I've got a rough idea of how it can be done, I'll see if I can do it and make a tutorial... Stay tuned!
Thanks for this fantastic video!
Ahhhh..was stuck on this for so long, like two hours..., had no idea about you need to use self-reference explicitly . This should be fixed!!
I hope i can get Move to actor to work now... Thanks so much!!
thank you....you are so awesome
Wow...fantastic!!!!
This is very nice, thank you. It always helps to have someone explain it so it seems so simple, much better than playing around with it for hours on end. Just seeing everything else I could do with this so easily helped a lot! Personal note: My first thought upon seeing "Upon success" was to have 5 AI's move to the point of a pentagram and suicide on them - Should I be seeking professional counsel? :P
I did exactly as it showed in the video but my pawn still doesnt chase my character. Is there something prior that you needed to add that this video doesnt show?
How do you make the ai make a sound when it spots the player???
PLS help, when I open blueprint for main character and AICharacter, the only things there are the input ones.
OMEGA This is just amazing, in so simple steps, Thanks you
I'm glad that you enjoyed it, there's plenty more on the way... just let me know if there's anything else you'd like to see!
Virtus Learning Hub Ahh yes please can you tell us how to make ai that can fight, carry out different task just like in any normal games?
There's a lot of work required to created more advanced AI. If you follow along with learning blueprints you'll figure out how you can move him, create different behaviours and such. I will be making a video on more advanced AI shortly.
Virtus Learning Hub yes i'm trying to, thanks man.
select the third person template.
these are helping me a lot :D
thanks a lot bro
I have a question. In my project when I start it dosen't start with you being a specific character rather it spawns a new one where you put the player start object. How do I make so that it starts from a specific character like you did.
That video is what I needed thanks dude
That's great, let me know of there's anything else you'd like to see!
Dudes, i see all these problems in comment section and believe me i had all the same problems, even in the ither projects, but listen its posible to fix all of these, my advice is to go watch this video many times to understand it, try to make a new Project and watch the video closely, look what is in your ue4 and what isnt, if you found the issue and you think that it is the issue, go watch other videos how to fix it and then comeback, this helped me alot!
I got a question if i want the AI to back to point A again after chasing me, should i use reverse ?
This is really an awsome channel for ue4 tutorials......Can you evern please make tutorial series for making andriod games on ue4 please?
Great video c;
so when doing the Pawn-Sensing can i put a lock on it so that it only sticks to the head of the AI because im making AI that will patrol and when stopping at a cartain point they will look around the room with their head and i was wondering would the pawn sensing follow the direction the head is looking when doing the animation??
you explains like a pro
Using this in my VR game I coined "Diablacita" thanks mate.
very very very thanks man (:
At first my pawn wasn't moving so I watched the next video and copied everything there and he still wasn't moving. Turns out my navmeshboundsvolume wasn't high enough and it wasn't covering the full mesh I was using. I scaled up my navmesh and the character moved!
Thank you, solved my problem
This happened with me too... thanks by the tip! =D
where do i find the navmeshboundsvolume?
He has a new video with an advanced ai, watch it, he just uploaded it because this ai on this video is messed up
Thanks for making this comment, I was having the same issue and now it's working thanks to you.
Hi Virtus,
I followed this video and my Enemy character isnt doing the walk animation, he does the Idle but when he starts following the character he just slides along the ground. Also he doesnt rotate to follow the player, he just stays facing the same way I placed him in the level and once my player is out of his view he just stops. Any help would be great cheers.
Great videos. I do have a question that's bugging me. If you made the game multiplayer how would the ai know which pawn to move to. More or less just curious about that?
mine only has the input nodes?
Could you make a video on making animals roam and run away from you. I can't find a tutorial on it and your really great at making them!
great tutorial for beginners like me
the cast to thirdpersoncharacter node isnt working whats up?
Hi, let me ask you if there is any AI tutorial or something that sort of explains to the protagonist what they should do when starting the game and then start the game? Thanks!
when i try the first time the aichar don't follow me but i discovery that the nave mesh must be in certain position to see it you must press p and where is green is where the ai can go.
Oh nice so I don't have to use the ai controller component. Thanks this this was just what I needed.
I can't get this work. You have a lot of other stuff in the third person character blueprint than I have. I've deleted only jump, walk etc and only few nodes was left there. I don't know if this same procedure still works with this newer version of ue4 editor?
I have a question: most ppl say do not use cast that often cz its gonna the game slow; however, on AI part, I've seen everybody using "cast to" node everywhere. I am very confused, can I use cast to as often as it is needed, or I should try design AI without using cast to at all?
Thanks very much in advance, if anyone may help!
Thank you
Hey I use for that BP from Behavior Tree but I can't create reference to OnSeePawn(Sensing) because this event work only in BP_Class :( Any solution?
Any ideas on how to make the AI stop sensing/chasing the player?
I've been trying a few things, but nothing is working correctly, the AI continues to chase after the player even when the player is long out of range...
Is there a way to update if the player is no longer in sight?
no i dont
Now I want to have to restart the level when he catches up to me how do I do that? Help!
i tryed with the 4.13 version it dosn't work but with 4.12 version work :( help please
do you have a tutorial where you can have the characters attack/collide with enemies
I got this part down, how can I get the player to attack the enemy and the enemy reacts with an animation
is there a way to make the ai patrol around and when he sees you he comes to you and attacks you?
So cool
So How can I set the Ai to move to the selected object not main character. I tried a lot but not working
I can't delete CameraBoom and FollowCamera both of them have Inherent on there name in components how do I remove them?
nice, can you make a tutorial for making AI from scratch, like cube following other cube :)
If i want to make the enemy more slow, how can i do it?
In the game I want my players to give commands to the ally bots how do we do that?
Dose someone know how to stop the Ais running annimation when he is running into a wall or something simmilar
How do you make the ai follow the player even when not in its peripheral vision?
I dont know if you still read these comments, but I am trying to make it so the AICharacter Pawn, goes and attacks another pawn, which is a copy of AICharacter, and i followed the video, but i just made it so it follows AICharacter1, instead of third person character, but it does not work. can you help me?
Can't get it to work with the car.
Can you help me?
Sorry am late but need help, what if I want to make the AI just wander around aimlessly until it sees me, then it would run towards and get me,
awesome, thanks! how can we tell the dude to go back to its place to hang out after we escaped? thanksssss
Hi, I've a little problem with my blueprint. I've created an Ai enemy that should kill me by touching me but it killed me at the very begining of the game... like he could fly and go through walls... I don't know how to fix it. Have you a solution ? Thanks and very nie videos ;)
Tip: you can press P or click Show> Navigation to show the navigation bounds
Can you have multiple nav mesh volumes?
is this compatible with the 2d you are doing?
But what if I had ranged hostile entities? How do I make then stop at a distance and shoot at my character? Thanks for this tutorial :D
thanks for help, just at 3:06 you said let's delete all the input stuff, but the main blueprint scrypt is there.. i think because of that enemy ai is not walkin, just sliding.
if you are doing something good, do honestly :D
I am unable to reference self. Any pointers? Thanks.
Hey man, nice tutorial. I loved! I'm trying to make a AI, but I'm having a problem! I made a AI and I made a damage system and I define 4 animation of attack, after this I did a random var to define each hour 1 different attack, do you know? Like the first time the AI attack with the animation 1, after I just run and the next attack will be random. My problem is, when the AI attack, the others attack too, wherever they are, and I have no idea to fix it. Can you help me? How can I make a AI attack separated, where the first AI is not linked with the another one? Thank you!
How do I set the speed of which the enemy is moving?
Can someone please help I made the character but when i deleted the input i didnt have all the extra stuff he had
Does this work for side scrollers?
Hi, i'm trying to make the AI follow my first person shooter character, but for some reason he doesnt. I'm pretty sure i copied all of the script correctly. I used a copy of the third person model as you said. Also, the AI is in the NavMesh. If you see this, can you please HELP
Look at the video #43 Next video, I put in the SET Variable and it worked
could i do with UE 4.13 ?
Great tutorial, thank you! I tried it and it worked but i was wanting to have the enemy AI to approach the player from all directions much like the third person one in the tutorial but I'm using the side scroll template so the AI only follows along the x axis going side to side. Wondering if you have any ides or suggestions.
I dont think you will ever get any ideas or suggestions.
Well, youtube auto-generated subtitle also thinks of your pawn as porn XD
hey how do i assign vr component as self
How do I do this in first person
i had to do this a different way in my game since i couldn't get the ai to work properly in this way
Dumb question, on my AI I have them set to wander around to random parts of the navigable area of the map. Where do I tie in the On See Pawn portion of the event graph? Im using the first person example map to work this all out and have imported my working blueprint for the wandering AI, and all the anim starter pack, third person stuff and all else is working fine.
the AI will follow for a few seconds then just turn and walk away.
It follows me, but there is no animation? I'm using sk_mannequin but it has animations already.
U did not cover the animating part how to make character when see u start running and when not see u its idling around walking with animation
