Unreal Engine 4 Tutorial - AI - Part 3 Chasing the Player 

Dude hands down you present much faster than the meme online training Epic has on the same subject, all respect and hope you keep pumping those tutorials. They are the best I've found right now.

Watching all of these back to back I've noticed you explain the same thing in every video. Honestly I like it because your cementing facts. I can't wait to get to the point of learning where I don't have to look up a tutorial for everything that I do

Nice love to see some good content being uploaded. A lot of the other good tutorial makers have vanished so keep it up! :)

Great tutorial so far thank you - looking forward to the next part

Thank you for this very useful, well explained content!

Note: If your pawn is standing still after creating your task and testing, check to make sure the task in the tree has your target vector assigned as a key.

for anyone doing VR, make sure to use get player pawn and not get player character

Thanks for your great tutorials Ryan!!! You r an excellent teacher man

Thanks, i really enjoy to see your tutorials.

Showing the area where they can see can be super helpful.

Your videos help me a create and understand how AI in unreal really works. You saved my game hahaha

Your videos are so great dude, thanks a lot !

Dude these videos are amazing! Thank you so much

I'm really enjoying the AI stuff man.

Thanks so much Ryan!

Eagerly awaiting the next one. They can't come soon enough!

Great tutorials on this subject! :) It is tough to find good ones.

Great tutorial mate, thanks

Smoothing the AI pawn rotation... My dreams are realised, thank you mate

Thanks for the tutorial Ryan! I found an alternative method for getting rid of the stutter: Random navigable location causes the direction stutter because it constantly adds an offset to the player location forcing the controller to turn left and right a little bit every frame even when standing still, if you just use get actor location it goes away, if you want to smooth that out further you can plug the actor location into a vinterpTo before setting the blackboard vector

So cool! Currently working on a project where I need exactly this. Can you make a tutorial how to implement custom C++ logic in the AI?

Thank you so much you have no idea how long ive been trying to fix this exact problem. LMAO my game is supposed to be released in 60 hours and without this video i wouldnt have been able to have improved ai,. thank you thank you so much you are a life saver

Thank you!

this guys tutorials are the only ones that work every time on the first try. i have tried all the other ue4 youtubers but it seems like no matter how many times i try them it fails halfway but laley is the truth. dudes the fuckin Drake of gamedev

Thank you for this amazing series, Not sure if you go over this in a future episode but how would you change the movement speed for the AI, so it walks when it doesn't see the player but starts running when it does? I've looked everywhere and cant find anything explaining it!

Hey Ryan! These are wonderful tutorials your're making, I learned alot from them! :) I'm making little project and have a small problem. Could you tell me how to make enemy stand still for a while right after he looses player from his sight range? I was trying to rearrange nodes in behaviour tree (so "wait" is before "move to random location" but despite this enemy always immediately starts to wander around after the player is out of his range (I want him to stop for a few seconds and then make him wander randomly). Thanks! EDIT: Nevermind, figured it out ;)

Hi Ryan, Love the content! And was just wondering how would you add music while the so is chasing you and make it fade out when it can’t see you anymore

Amazing!!!

ryan my dude, hope your well? wondering how do you get this to work with a 3d side scroller? thanks man legend

If you were so lucky to find this comment, I highly recommend you put the "Can See Player" on the left branch instead and set its priority to "aborts lower priority". This way as soon as the player is spotted the AI will interrupt what it was doing and chase you. It will make the following lessons a lot easier. thank me later.

You can use an object variable to be used in the "move to" task, just set the base class(under key type, in blackboard details) into "Actor".

Btw, youtube thinks you’re saying “porn” when you’re saying “pawn”, I hope that doesn’t have any negative effect on SEO 😱 (I watch with subtitles) Anyways, love your content, keep it up! 👍😊

These tutorials are easy to follow and understand which is more then I can say about most tutorials. However I cant understand why no one will take a couple of minutes and answer questions that people have. Some of the questions I can relate and could use an answer myself. But I am going to take a chance that someone might answer a question. I can not get the AI to chase me. What can I do to fix this? They will spot me and orbit around me moving from location to location randomly but that's it. This is not the first time this question has been asked but it is a rather important question so I'm asking it. Thanks

and it just works!!!

I really like this series. Very easy to follow! #mediaartssbcc

Nice tutorials, thanks. I'm assuming that this will NOT work with multiplayer games because of the "Get Player Character" node only getting the first player. Is there any reason you didn't pass the player "seen" into the Blackboard or even player location to allow it to work with multiplayer ? Would this work ?

I'm coming.

Thanks for the video! Is it possible to somehow use Ai Move To instead Move To in Behavior Tree?

Hi Ryan! I would like to know how we can make AI run away from player. Also is it possible to make this AI to a bird-like character so it can fly around?

which video covers setting the status of enemies/friendly.. because i made one that chases and one that just roams around, but the chase bot tends to want to chase the other npc instead of the player, i'd like to be able to distinguish

a good tutorial man but I noticed an insignificant "bug" If we can say that, at least in my case the AI chase me and if I stay still for a short while my AI keep moving arond me and after it run away like it lost me, anyway you helped me a lot, thx!

You could just use the build in function of AI controller called "Move To Actor", no need code this function on you own. And for chase more believable or make the NPC more believable, NPC should chase to the place that lost the player and move along the player's last velocity for some distance. Thanks for the tutorial though : ) Maybe you could explain why should we use the behavior tree instead just code those thing inside the AI controller component? I don't feel the behavior tree can be big help for the NPC behavior, specifically those flow control seem not so convenient inside the behavior tree...

Hello ryan, just i quick one, if i was to add another enemy do i just duplicate the original and change the anims, blueprint for it to work on another?

first the flow control was on none, so the ai find me go to my last seen vector location, after that he plays dumb again and go again to a random location, in flow control i changed the observer aborts and now the ai follow me like i want, i dont know why this solved my problem, please tell me what changed when i abort both both ? Again love your work

If you are doing this in UE5 Simple move wont work you will need to use the AI Move to Node set the vector blackboard key to the destination get the player charactor and plug that into the target actor then finish execute.

I don't know what I did wrong, but my npc doesn't chase my player. it only wanders.

Hi Ryan, I'm new to UE4, lots to learn. Can tanks be AI controlled to chase and shoot at player? It would be great if you could point me to a tutorial you've made that may offer some assistance. Thanks in advance.

Is there a way to shorten the distance that the AI can see you and begin a chase?

Hello to everyone and thanks to Ryan for the great Tut.My NPC just stands there, will no longer follow NPC.Does anyone have the fix That would be great.Thanks

Nice! But i think i'm gonna stick with the AI I have :P from your other tutorial

If a fog was created, could this applied in the same way so that the player is chased by an unknown entity?

I'm having some trouble with my NPC blueprint. For some reason, my viewport and component windows are disappearing with no way to get it back, and I keep having to create new ones. Does anyone know how to fix this? It's become a major pain in the butt

Is there a tutorial for walking and chasing speed of the AI ??

Can you do a video on how to end the game if the AI catches the player?

My AI character is not rotating his face at the random point it select, its face is in forward position and moving to left side. Please help me

Ai controller won’t set the value of the bool and Idk why the only thing I’m doing different is not using the mannequin first person character (which when I did previously it worked without an issue)

How do i get lower priority because its not showing up in unreal engine 5

How can I make my ai follow more than one player? in mode multiplayer ??

I'm having issues with the auto success range. Lets say I go through a door and hide in there and the AI last sees me in the doorway, once they reset and I go near the door the AI instantly is alerted even with their back turned. I've looked all over the place trying to find a way to reset the success range, clear the last seen location, or really anything to help remedy this. If anybody knows how I can clear this when the AI is set to patrol again please let me know.

Can you Make an AI chase 2 different characters? Like co-op. 2 players and one AI. An AI that attack both players. :) ???

How do i get the AI to change 'Max Walk Speed' when it sees the Player, Then change back when the AI looses sight? My AI walks around and i want it to run after my player

@Ryan Laley You have the best tutorials, can you help me with my problem? Please, I need a help

really want to get into game development in UE4 as I already know how to model and texture etc in blender so would be good to create games. Thought struggling to get my head round some things. Seeing something like this just makes me appreciate the amount of work game devs put into game creation especially in games like Red Dead Redemption 2 and all AAA games for that matter, with all the complex game mechanics they implement. Can only imagine how complex the coding is.

How do I make the ai follow closest player ???

Have you done something like this where the Ai runs away from you?

How do I make one AI chase another?

Mine only has Self, it can't do both?

If I simply jump over my enemy, he loses track of me. Is there a setting in perception I could tweak perhaps, so that he's aware of a fixed circle around him?

This is a very good tutorial series but I'm having a slight issue. The AI moves to the player's location but it only starts moving when I stop. Plus when it does move it rotates in all different directions and looks weird. Any help?

i have a quustion: so i have this giant worm thing and i wanna make an AI for it. heres what i want the AI to do: when its idle to stay underground and randomly jump in and out of the ground, when its alerted to rush to the player- still underground and randomly jumping out of the ground

Hey! I was wondering if you or anyone else could help me with an issue I have. So I made the AI move random locations and the track of me, but when I go in front of the AI it stands still forever.

Can you show how to make an npc jump up to a higher elevation to chase the player?

my npc keeps running away from me instead XD like it chases me and then when it gets close it runs away

mine isnt working, it is still dumb probably because im doing first person (maybe)

Outlast 2 door opening and closed character animation please :) and ai bohiver attack and heath systems sound attackk system pls

Hi Ryan Im making a game using first person and i have a third person AI, everything was working up until the part where i gave third person character the ai stimuli but now the problem is that CanSeePlayer won't turn true i dont know why

what if i want the AI to follow the player at all times can i just remove the go to random location sequence?

An enemy type that only attacks in packs would be cool.

👍

5:10 at this moment my character can attack. After the bot rushed to catch up me, I hit him. I was very surprised when he started to run away from me

why does my ai character finds random location once and stops

Is anyone else's video 'shorting' out for this tutorial? Every time I try to watch it, this green bar appears at the top, then a gray-black box takes up the whole screen. Am I crazy?

1:56 Thanks for tutorial but there is not a choice both in the new versions can you help about that ?

My AI just round around and when I get in their vision, they just stop. And start running random when I get out of their vision. Pls help me. It is not my text, but I have this problem too...

Is anyone got this massage ? Blueprint Runtime Error: "Accessed None trying to read property CallFunc_GetPlayerCharacter_ReturnValue". Blueprint: FindPlayerLocation Function: Execute Ubergraph Find Player Location Graph: EventGraph Node: Set Blackboard Value as Vector

I'm using the First Person BP, and the NPC never seems to spot the player. I've follow your instructions very closely, but in the last tutorial is when you set this up. Any thoughts as to why it wouldn't spot me at all?

Hey Ryan for some reason my AI isn't sensing the Player character! I have the stimuli in the player!

My AI just round around and when I get in their vision, they just stop. And start running random when I get out of their vision. Pls help I’m very new heh

IDK why but I can’t open NPC... it does open but it’s just blank

Isnt PawnSensing better?

I evade the AI but still it insist in finding me,no matter if I jump to the other side of the obstacles and hide..the AI always manage to get to my location really fast..

@RyanLaley Can you help me?

In abort options i only see None Self please get to me as soon as possible

My ai walks Sideways lol

The AI doesn't start chasing the player. It just keeps on going to random locations

Left hand path......

Try to make AI kill the player like FNAF

This doesnt work in Unreal Engine 5.

My AI is not chasing me, I've done this tutorial three times already.

I have followed the tutorials step by step, detail by detail TWICE and this does not work. The NPC runs around aimlessly and clearly does not see me.
