Very clear, easy to understand tutorial. Thank you so much for this excellent video!
Thank you so much, man! Your tutorial really helped me!
Cheers, this is helping me figure out my work flow.
Very cool looking tutorial!
great tutorial going to try this in UE5
You helped me a lot! :)
Thank you man 🙏💙
Bestes Tutorial für NPCs! ❤
I am a beginner in this domain, can someone pls clarify what NPC stands for? Non Playable character or Non Programmable character? or something else?
@@navneet2649 Non player/ playable character
@@RSProduxx thanks a lot 🙏🏻❤️
Love the tutorial. Really nice work.
I used UE5 to test this. It works perfectly except the character runs constantly for some reason. It has a different Walk/Run state and a groundspeed variable.
Goes beyond my ability to understand what determines the speed actually in this case.
To adjust the Walking Speed of the NPC go the Character Movement -> Details. Search for "Max Walk Speed". This is the same as in UE4.
thank you so much!
always the best
helpful, thanks
love!!! ❤❤
you can make a video about pedestrians, that if the car rides on them so that they dodge, as is done in Driver San Francisco
That's actually pretty easy, so you put a collision box around the AI, than cast to the Car. On begin overlap set the State to the "Dodge" State. I would combine it with a Boolean to check if the Car is Driving.
Very informative, thank you!
How would you set up a path for the characters to follow to reach a destination?
With Target Points. And I think this could help as well to understand the System: ua-cam.com/video/fYSEshgc8WU/v-deo.html

Man..you are just freaking awesome
Helpful!!!!!!!!!
Thanks!
Thanks! This worked for me. However, for me the actor isn't facing the direction they are walking in, is there way to fix this?
Sounds like the Animation is wrong or the NPC has the wrong direction in generell. Compare it with the Third Person Character Template.
I followed the tutorial identically. Very nice
How do I adjust the distance time to the target?
With the Max Walk Speed inside the Character Movement of the NPC
How do you make a character move it’s month for talking
I love your lighting set, can you make tutorial please
Since I am not the Creator of the Map, it wouldn't be fair. But you can get this Map from the Marketplace:

@@Seredias. thank you very much man
Hi Thanks for this tutorial! I have a question. When following your tutorial, from target you say to add in Int + int but the option is not there? Every other option you have displayed is fine except the int section. Have you any ideas?
I guess you're using UE5? In this Case you just search for + and connect it. Unreal changed the Math Functions in UE5.
This is at 8:31 and I don't get the same options as under the subheading increment as you do, any thoughts? :)
@@reaalex I know which one you mean. If you go from the Target and search for + you will find the function "add". Do you use UE5?
Thanks for your help that worked! I have actually went through the tutorial and when I click play as the AI moves to the desination points the client just freezes. I suspect it has to do with the The event graph in UE5.1 is different to the version you are using at 4:46. I tried to stitch things together what looked right but I think it's come back to haunt me :)
It may be because the mannequins have updated
would be nice if this included the details from the other video, or if this video made it more clear there is a prerequisite video. I'm totally stopped at 5:46 because I have no idea how to make this graph and no idea which video of yours it's in.
Well there is no prerequisite video. I explain everything necessary inside this Tutorial. At 5:46 the State is just the condition for the matching Animation State, which was created at 2:05. The Graph itself is the default Animation Graph from the Third Person Template.
Hi, Thanks for yout great tutorials! In this one I have gone over everything and cant figure out why my character wont move to the point. The character will face and look at where it needs to go but wont move. The nav mesh is fine but I can see it wont get past 'AI move to node' in the logic. Using 5.3. Any help would be greatly appreciated.
Usually the Nav Mesh Bounds Volume is the Problem. So if you press "P", the Character and the Target should be in the Green Area. As well there needs to be a possible way (Green) between the Character and the Target. Did you use a Custom Character? If you yes, try to copy the default Third Person Character and try it with that.
@Seredias. thanks so much for your quick reply! Yeah everything is good and in the green. It turned out to be a hidden mesh under the floor that was messing with it. ugh.
HELLO, I wonder to know how we can set our target points random, thus the pedestrian moves randomly, Thanks in advance
Yes, that's possible. Between the "AI Move to" and the Target Point, you can place a "Get Random Reachable Point In Radius".
how we can get character animation blueprints the mixamo gives us only the animation sequence which is not available as a anim class
There is a link in the Description, how to convert the Mixamo Animations to Unreal Engine
Hello. pls help me. When i want to start playing my game i cant because i have an error like this : Infinite loop detedcted. Pls help me it is very important for me
In which function was the infinity loop detected?
Please tell me, can I use this system with characters with Meta Humans?
Yes, you can. As long as you import them right: ua-cam.com/video/IJVxpsS1nVo/v-deo.html
It's me again, now that I have the target points all set up and looking nicely/working as intended, I want to mix things up and give the character more actions. For example, walk to target point 1-2-3 and at target point 5 idle for a period of time, target point 6 walk, target point 7 get on the phone, etc. Is there a way to change the state on a set target point? I hope I'm explaining it right...
Sure, you just need to change the State Machine. In your Case: "Walk" State to 1-2-3, than "Normal" State on Success, delay (period of time), than "Walk" State to 6-7, than "Phone" State.
@@Seredias. I'll do my best to figure out how to do that. Don't suppose there's a tutorial on it on your channel, is there? I've only been tinkering for about 1 week with unreal, still have a lot to figure out.
@@DanielsWacher Well the tutorial you are currently commenting under shows all the steps you requested. And what I wrote was a step-by-step description. But I can also understand that it's not easy for a beginner since my tutorials are advanced. If you want you can join the Discord Server, so the community can help.
What is the use of nav mesh bounds volume?
It is the Space where the AI is able to move. The Green is the possible Area.
hello, thanks for the tuto ! but I have a problem. My character doesn't go to my target point, the AI Move To always fail. I have checked the nav mesh, it's good, and i don't know why it can't move
Okay so I guess your Character is a copy of the Third Person Character. And the "Nav Mesh Bounds Volume" include the Character and the Target Point, right?
@@Seredias. yes
I solved my problem ! I had a recast nav mesh or something in the sky and i deleted it. Thanks anyway for answering
For some reason my NPC just stops after reaching the first point... There are 3 of them added. Any clues?
Using unreal 5.2
So the loop at 9:40 needs to be correctly and the Target Points need to be set 11:10
@@Seredias. Everything in the BP is exactly like in the video and Target points are set. For some reason it can only go to 1 point without continuing to the others, regardless of order or distance, let alone loop or anything like that. So I can set in index 0 point 1 or 2 or 4 and it will go to them, but it will not move past index 0, it will not follow the other target points.
@@Seredias. Never mind , found the issue. The target points were above ground, just had to use "end" key to drop them to the ground and now it works like a charm. Thanks for the awesome tutorial!
Thank you Dude! I wouldn't have figured it out myself@@DanielsWacher
Which Animation asset do you use?
I imported all of them from Mixamo (link in the Description).
I am a beginner in this domain, can someone pls clarify what NPC stands for? Non Playable character or Non Programmable character? or something else?
Non-Player-Character
@@Seredias. Ohh so "P" stands for "Player"😯 Thnaks😇
good tutorial, but in UE5 the animations don't seem to work. that npc moves without playing its animation. and I have followed your every step.
Did you use the Original UE5 Third Person Character or a custom one?
is there a way or do you have a video that i can be the npc, like changing into it and then playing with the so called npc?
What do you mean by that. You know that NPC means Non-Player Character. So a Character that is not a Player, to make the World more realistic.
@@Seredias. Yeah i mean like followers or the onea that are mostly in your tribe or clan or whatever. The ones you can recruit to fight by you side in some games and use them as guards, followers etc.
@@diogonz7777 Ah now I know what you mean. Yes, that make sense. Good Idea, I will make a Tutorial about it.
@@Seredias. Thank you very much. i will subscribe and hope i will see it soon.
hello friend do you have a video on ai crowd avoidance?
Not yet, but since I currently work with MetaHumans, I will try to integrate this.
your amassing sounds great@@Seredias.
hi the walking is working but the phone is not for some reason
Did you setup everything inside the Animation Blueprint 5:30?
Hey, Great video! I'm new to UE4. I have an issue when the loop of the animation is done, then the AI goes back to the position when i started playing. This results in the AI talking a few steps then it repeats so he doesn't continue to the target point. Do you know what might cause this?
Did you use the Standard Animation or a custom one?
@@Seredias. I used the animation pack that you linked in the description, but I used the standard skeletal mesh. I used the MOB1_Walk_F. I did create the animationBP from scratch since I couldn't figure out how to change the skeletal mesh, maybe the problem could be there?
@@Lingosaft Yes, definitely the Problem came from there. Please try out the Standard Animation, to see if that works.
Where should I get Blueprint?
Which Blueprint?
But how to connect to animations transition?
You can just use the State Machine for this. Just set the State in different Situations to switch the Animation.
@@Seredias. thanks man ill try
the character goes to the first point and then stays there, any help?
Please debug this function 9:50 to see if its continue after the first Point.
nevermind, my code was worng
@@Seredias. Excellent and totally clear tutorial, thanks so much!!
*EDIT* I had the same problem, In my case it happened because I put the targetpoints a little bit above the ground and they must be stick for some reason. Now everything works perfect. I love it :)
yes your caracters are sliding .)
i did this works perfect except walking state he just plays animation on the spot but is not moving
Did you placed the Nav Mesh Bounds Volume, corretly? So that the Start and Target is inside the Green Area?
Yea, i have one for the whole map, i have other npcs that walk randomly around as well as ai enemies that also chase and attack me , is just this one that doesnt move, i will try tomorrow after work to move him somewhere else on the map and see how it performs else i will wait for my freelancer to debug and fix it for me 🙏 ill get back with feedback after i move him somewhere else on the map😊
this did not work, instead of walking straight forward, my npc goes to the right, and won t go to the next target point.
I would recommand to check the Event Graph again 7:30
Does you NavMeshBoundsVolume include all Target Points?
My character likes to hover across the map add top speed in idle animation😂
Ive watched the vid 10 time finding the problem but i cant figure it out
Did you use the Unreal Mannequin or a custom Character?
@@Seredias. i duplicated the third person character and replaced the mesh
@@mikedegraaff44 that never seems to work for me either.
player not move please tell me what i do
Did you placed the Nav Mesh Bounds Volume 11:30 and is the Target Point in the Range of the this Volume?
Nav mesh bounds I try apply but not working,😭😭😭
@@freedomhindi4949 With "P" you can see the range of the Volume. The Target Points have to be in the green range.
I do
@@freedomhindi4949 And did you set the Variables of the NPC 11:00?
Hi Seredias, cool video. Thanks for sharing that. I am
working on an Al engine that describes
human behavior. I
believe it can also be used for games. I seek an expert opinion on that. Would
you be open for exchange?
I am glad that my Tutorial helps and by the way I plan to make a hole Tutorial-Series about it.
there is no state option
Did you create the Enumeration? 2:02
@@Seredias. yeah
@@ugly3498 Okay where do you need the State Option?
@@Seredias. i forgot its somewhere in ur tutorial
@@Seredias. wait is this tutorial for attacking npcs?
Npc move there arms while breathing🤣
Man hört so das deutsch raus haha
