I am LOVING these tutorials! Honestly one of the best AI series i have found yet. I never really fully understud how BPIs work but the way you use them and explain the usage of the functions just made it sink in so easily. Also for people having issues with the line of sight ( as i was ) if you have anything blocking the character mesh like a shield in my case make sure to also check ignore visibility for the collisions otherwise it will cause a loop in the move to line of sight!

Hey Man this is an Absolute gems of tutorials and this is making my game look really good thanks a lots 🤩 For those who have an issue with the Line Of SIght at 27:00, once you did all these, make sure that the Line Trace Channel is set to VISIBILITY and then make sure that your character that you are playing with ignore the VISIBILITY trace collision in both mesh and the capsule component, this should make it work.

Ok first off I have to say how grateful I am that you've been so generous with your knowledge of this subject. So Thank you and by the comments and they way you have replied to everyone is just rare and speaks volumes to your character. Ok with that out of the way back to the game. So I just finish with the the ranged attacker but for some reason he isnt looking at me as he fires but i do get the line trace to me and everything else is working perfectly. some things to note are i am not using any of the Manny's however have converted converted the anim bp to my character except the(control rig and disabling the LegIK) but if that is the issue let me know... Thanks again and seriosly I hope you keep blessing us with your wisdom! :)

[@AliElZoheiry]

Hey Adam, I really appreciate your kind words and support 🙏 I love sharing my knowledge and helping people, and I'm happy that you value that as well. Regarding your issue, there are 2 things that are responsible for getting the character to look in a specific direction. 1- it's the SetFocus function that we call on the AI controller 2- it's the rotation settings on the character movement compound in your enemy pawn. You should have "Use controller desired rotation" checked and "Orient rotation to movement" unchecked. Double check these things and hopefully that will fix your issue

Again a great turoial ! Well done, hope you will keep at it !! I Have so much to learn from you ^^ ! One issue tho, when the range AI doesn't find a cover point it just stop and run the query in a loop, I can't figure out how to fix it yet, but it's a good exercise !

[@AliElZoheiry]

Hey there! Thank you for the kind words! I'm thrilled to hear that you found the tutorial helpful! As for the issue with the range AI, it sounds like an interesting challenge, and I'm sure with a bit of troubleshooting, you'll find a solution. Good luck and happy learning! 🙏

[@JonWith1n]

@@AliElZoheiry Thanks for the answer :) Sadly, i think I will give up for now and just design so there is always a cover point -.- ... thought I had something with a custom task that run the querry and get the result as an array of locations but the lenght of the array is always 0 even when the EQS find a valid location... so it doesn't work either, and if the query doesn't find a valid location it will keep looping over and over, I need something I don't know yet I think so the query stop when no location is found... but I can't get my head around it ... I must keep learning I guess ^^ !

[@AliElZoheiry]

@@JonWith1n A simple solution is to put the EQS task in a "selector" in the behavior tree, and if it can't find a location, it will fail, triggering a backup task in your selector (which should be placed on the right side) that way you can get a random location or do something else if the EQS fails to find a location

[@JonWith1n]

@@AliElZoheiry Oh ... it was that simple -.-, I kinda feel dumb for not getting it on my own but I got a better understanding of the selector node now. Thanks a lot again for taking the time to answer me, if eventually you end up puting a paid course on udemy you can count me in !

Just wanted to comment an issue I had that others might. When making the Move to Line of sight sequence at 21 - 27 min If the EQS grid isn't big enough the AI will break as it can't find a move to point until the player comes back in range. PS this series is great. Thanks for the in depth tutorials

Just an obligatory thank you again, on to part 7! Was wondering would you advice to first follow the whole damage tutorial or do you think I'll understand the workings of it if I migrate it into my project like you're doing in the next video?

[@AliElZoheiry]

Thank you for watching and commenting ☺️🙏 I would recommend at least looking at the damage system to see how it works, and if it's clear then no need to watch the full tutorial, but if it's not clear from the code, then I suggest watching it first before moving on

[@HusmanGames]

Sounds good!@@AliElZoheiry

[@AdamWoolnough1981]

you are doing great, should we be casting every time an enemy shoots something, interface works ok for me to get location

[@AliElZoheiry]

Thank you for your comment! Glad you're enjoying the videos. Depending on your use case, a cast can be sufficient, but if you want to avoid it, of course interfaces are a good solution for that

[@rezaj.mousavi7310]

greate... pls make a video for physical animation hit reaction bullet when shooting to enemy ... thanks alot

[@AliElZoheiry]

In the next video I'll be covering hit reactions, but not physical animations, just regular hit reaction animations

[@nikgiak2994]

@AliElZoheiry , amazing series! TYVM! Probably a future patreon here :) Only two things. First, I'm suffering to interrupt and update the "Move to Line Of Sight". It seems that the "Can see Target" decorator from the "Evade" branch is not interrupting the other branch's "Move to". Even in your video, at 27:04 - 27:07 (it reaches first the old line of sight) ,you can see the npc not interrupting the "move to" when trying to find another new position. It reaches the old one first and then moving to a new one. Any ideas? The second is a suggestion if I may: How about another episode, creating a pet npc with its own BT (perhaps combat pet), to follow this NPC, accept commands etc. Ty again, b well!

[@AliElZoheiry]

Hey Nikgiak, to have a decorator interrupt the currently executing branch, you need to set the value of "Observer aborts" which is an option on the decorator. Observer aborts = lower priority, means that if the value becomes true, it interrupts any lower priority branches (branches on the right) and immediately starts executing the branch with the decorator Observer aborts = self, means if it is currently executing the branch with the decorator and it becomes false, then it interrupts itself and moves on to the next branch. Hope this helps, and I will surely consider the pet AI, a few people asked for something similar as well

[@nikgiak2994]

Hey@@AliElZoheiry ! Thank you for taking the time to answer! I do have it set as "both". It does interrupt then it sees the player while searching for a line of sight position but it does not interrupt while moving to a line of sight position but the player moves again and that line of sight position is not good anymore. Instead of stopping the current move to line of sight and run again the "move to line of sight" sequence to find another position, it finishes the previous move to first. You will notice the same happening in your video/code as well at 27:04 (it reaches first the old line of sight). Now, if the query grid is big, the NPC will run far until moving to a new line of sight. Can't wait for the Pet tutorial!!!

[@nikgiak2994]

UPDATE: Ok, this is happening because the BT Decorator "can see player" remains false while the player moves in different "out of sight" positions hidden, while the NPC is trying to reach the old ones. There is no change to the decorator variable, this is why the sequence is not interrupted.

[@AliElZoheiry]

@@nikgiak2994 Makes sense, sounds like smart behavior. If the player remains out of sight, the enemy goes to the location where they think the player will be visible.

[@nicbleu]

I wonder if you know anything about the new machine learning plugins called learning agent, using machine learning can be good if you want to have unpredictable behavior, also complex terrain where an agent need to follow a player that is jumping on platform , in a un-scripted way like the nav mesh bridge for jumping. I could only imagine creating simple neural network to make tasks for the behavior tree. I think it would be very fun to combine the two. Do you think it could be done ?

[@AliElZoheiry]

I haven't heard of the plugin, but I've read a lot of papers doing some very cool stuff with machine learning and characters in game. It's all possible to do in Unreal, it will definitely require a good amount of knowledge of both C++ and machine learning, but it's possible

[@kuchukboromdebbarma2117]

the amount of training you will require is gonna be insane trust me. Almost impractical for shooter AI

[@thedefaultcube1218]

Thank you. Amazing series. Subscribed. If you keep up this level of content will join patreon. Quick question, dose the system scale well? MMO with client and server, multicasting. Im looking to get a horde of zombies (say 20) and soldiers say (10) so would this sytem work with other clients and these NPCs all acting out there AI logic with eachother and players? Thank you in advance. Awesome you take the time to answer everyone

[@AliElZoheiry]

Thank you 🙏 glad you are enjoying it! I will try not only to keep up this level, but hopefully keep improving. The system itself will scale easily, but so far everything we've done is not server replicated, so it's going to function for single player games only, and generally speaking the AI tools in UE are made with single player in mind, though they can be extended for multiplayer with some extra effort. Regarding scaling to hordes of enemies, that is also no problem but it will highly depend on your enemies behaviors. If each enemy is running a complex EQS on every tick, then having 50 enemies at once will definitely take a toll on your machine. So you will need to optimize your behavior tree, but everything we've done so far is not programmatically expensive at all and scales well

[@85matticus]

Best video series ever. Very informative. I am having a hiccup with the ranged character. When I hit play the range character zooms across the screen as far away as possible ignoring the eqs. Any suggestions? It seems to do this no matter what EQS I use.

[@AliElZoheiry]

If he's moving weirdly, just like sliding very fast across the map, then that probably means that the capsule of the character is colliding with a mesh that's attached to it. Make sure your weapon collision is set to "No collision" and same goes for anything you attach to the character

[@85matticus]

So problem solved my weapon had collision on. Now everything works great keep up the good

[@85matticus]

@@AliElZoheiry that is so funny I just sat here and figured it out went to add a reply to the comment and didn't even see yours. thank you for the quick reply though. What gave it away was I put the range behavior on the Melee character and everything worked fine so I just thought maybe the collision LOL

[@vidmaster7]

Hi, Ali. I really appreciate the hard work you have put into all these tutorials. I have followed the tutorials for the Combat Damage System (that was the first one I did), Projectiles, and all the Smart Enemy AI series. I am working through AOE damage and healing. The problem I have is that there are lots of conflicts with the various systems. I'm not doing them as separate projects. I'm doing them in one project. That means, for example, that I have a BPI_EnemyAI AND a BPI_Damageable. Some of the code is calling GetMaxHealth from one and some from the other. There are other items that are named completely different names. Do you have any tips on how to untangle all this? Thanks.

[@AliElZoheiry]

That's exactly what I'll be tackling in the next video, integrating the damage system with the AI series, and using the BPI_damagable interface along with the BPI_enemyAI in the same project. The hint is that the Damageable interface will be responsible for health and anything to do with doing/taking damage, and the enemy AI interface will be responsible for all enemy actions

[@vidmaster7]

Hello Ali, thanks for the great tuto. I would like to know at 14:34 the enemy get too close to the target and I don't want he cross near me. Didn't find how to manage. It is possible to get around the target some extra blue sphere, same you did for the enemy at 12:45? Cheers

[@AliElZoheiry]

Hey Sanz, glad you found this useful. You can definitely play around with the EQS, add some more tests such as distance to querier to make sure the enemy doesn't go too far from their current position. Or you can change the shape of the grid all together, you can think of generating points infront of the player only. Or you can also add a "Dot test" to eliminate any points behind the player. So you have options, just keep trying new things and learning about EQS and you'll find what suits you.

[@POPCORNGameMovia]

Hey Ali :) Very much appreciate your time and effort put into this tutorial series, helped me a lot :) I would kindly ask you a question please: How do I spawn the enemies in world using same ABP, but to behave independently. Currently having 3 AC on my AI (combat system, Enemy Stats and Inventory), but if I do spawn them with a simple "spawner" only the first one can deal damage, the others are not, and also if I hit one of them, all of them react to the hit, regardless if they are away and not being hit. I know, I am a noob on this :)) but definitely is simple to do this, but I am missing the correct nodes and logic to spawn them. (did used "SetAicontroller", did used "SpawnAifromClass" and did selected the behavior tree and class). Any suggestion on this please? Thank you and thank you! Keep it up! :)

[@AliElZoheiry]

Hey! Happy to hear that this has been helpful 🙏 Strange that your enemies are behaving this way, this shouldn't be the case even if they are using the same AC and same ABP, because when you spawn an enemy you create a new instance of all their components. The only reason I can think of is if your enemies share some behavior that is not part of the spawned instance, but that would be a very strange implementation 😅

[@POPCORNGameMovia]

@@AliElZoheiry Thanks for your reply! Yeah the only behavior shared is the behavior tree. Somehow I think I fixed the playing animation on all instances, but the attack system still does not work. Might it be for the fact that some actions are casting to a specific actor? I mean if you cast to AI Enemy Base, it spreads on all chield and instances of that actor, altho' the Combat AI AC is individual on all instances. A weird thing i've noticed is that sometimes there are 2 enemies that can perform the Attack Line Trace, out of 10 of them like. I even tried to duplicate and implement all of the components (BT, BTT's, ABP etc) and that somehow worked, but only for the single instance of each AI. If I do spawn multiple from same class I get the same result. Have to investigate more. Thank you and waiting for the next video on the series :)

[@POPCORNGameMovia]

@@AliElZoheiry UPDATE: I am sharing this here so maybe someone else will find it helpful. The AC where I have all combat logic is not shared, meaning that only the master was accessing it, but not other instances of the AI. I moved part of the logic into Base AI and now all of the instances deal damage. Now the question is why they do not work with the AC? I do want to avoid casting too much, and try to split everything so it is reusable for other AI, this is why everything I build is in AC's and interfaces. Any suggestions or opinions? PS: Combat AC is the only one not working, the other are doing just fine. Thank you!

[@POPCORNGameMovia]

@@AliElZoheiry LAST UPDATE It was a bad implementation of the ATK Line Trace. All good now! We are learning everyday :)

[@carlosbueno3534]

Hey man, your videos are great! Thank you so much for sharing this. I have managed to implement most features up to this part but I am currently having a problem with the pathfinding of the find cover. The enemy moves in small steps for some reason instead of moving directly to cover. This means that the enemy stops every two seconds, looks at me, and heals before getting to the point of interest. So basically the move to task is finished before the enemy goes where it should. Do you have an idea where the cause may lie?

[@AliElZoheiry]

Hey there! It sounds like the enemy is actually hiding behind themselves, so they think that they are a point of cover and they move one step back, then heal (thinking they are behind cover now) then realizing later they are not (because they just moved) and then they move one step back and repeat. At least that's my assumption based on your description. If that's the case, then the line trace to find cover is being blocked by the enemy or something the enemy is holding, so make sure that the mesh and the weapon on the enemy DON'T block the "visibility channel" in their collision settings

[@carlosbueno3534]

@@AliElZoheiry Thank you very much! That was indeed the case. Because I have hitscan weapons in my game, the collision for the visibility channel on the enemy was on. I have created a new trace channel for the hitscan weapons and disabled blocking on the visibility channel of the enemies and it works now. 👍

Hey Ahmed, if there is a wait node in your behavior tree after moving to a point then your enemy will wait a bit after moving. But in general if you move the enemy to a point, then start calculating a new point to move to, there will be a short, but noticeable delay between moving to one point from another. To get around that you have to already have a new EQS point calculated before the enemy reached their current destinations, and then have your enemy move to the new point when the get close to their current point, instead of when they actually reach it

Hello, thank you for the tutorial, it's been very good so far. Though, I have a problem with the ranged enemy: it just moves back and forth in the same direction instead of selecting a random point in the grid. I've seen that it creates the grid around the player and assigns different values to them, but the enemy just travels from one corner to another of the grid without stopping on some intermediate points. Also my keyboard doesn't have the numpad, so I don't know how to open the debug settings during the gameplay to see the grid

[@osmanbaba1485]

I believe to rearrange keys it was Edit > Project Settings > Gameplay Debugger then you can change to other keys. As for your other issue have you remembered to disconnect the EQM context from the player start to attack target.

[@Leonardo-zb6ho]

Nevermind, I forgot to select "25% random" in the EQS settings. I still don't know how to see the grid though

[@Leonardo-zb6ho]

I'm now seeing this, thank you so much :)

Nice! Glad you figured it out!

[@user-vd8sb8gb4t]

I have a problem where AI can't attack to each other, even thou I disconnect the condition where the player is the only target, help pls

[@AliElZoheiry]

Hey there, if the AI can attack the player but not each other, then I suggest debugging the perception settings, if they perceive each other (you can find that out using the AI debugger) but they still don't attack, then it's likely related to your "attack condition" not the perception

[@gamersantai7796]

CanSeeTarget decorator makes my NPC constant pacing around between 2 points and not attacking, but it chases if Player is out of sight, is there any solution for this problem?

[@AliElZoheiry]

Not sure why that's happening, try to debug your behavior tree and see what nodes it's switching between and try checking your collision presets making sure that the trace from that decorator isn't hitting something that it should not hit

[@gamersantai7796]

@@AliElZoheiry yeah so i was using AlsV4 char as Player, changed the AlsV4 collision presets the same as ThirdPersonCharacter and it works

@@gamersantai7796 indeed the default third person character has the visibility channel ignored on both the mesh and the capsule, so that's important for this to work

Hi! I've got a problem with the health. My enemy just heal 0.3% not 100% like yours and i don't know why this happens

[@AliElZoheiry]

Make sure you're calculating the health percentage correctly and passing the right value to the heal function. If it still doesn't work, feel free to join the Discord and ask your question there (link in the video description)

[@ohtontheknight3879]

I got a problem for some reason if the enemy see an enemy while investigating it goes in to attack state and just goes for the player

[@AliElZoheiry]

Check your handle sense sight and make sure it's setting the attack target correctly

​@AliElZoheiry been looking at it and everything looks the same

[@rugbyf0rlife]

So far these guides have been fantastic, but I've run across my first major snag that I can't seem to solve despite copying these BPs and trees pretty much exactly. At 27:00 you implement the LOS interrupt decorator for the LOS search and attack and evade sequences. However, no matter what I try, I cannot get this to run properly. It only ever loops in the "get LOS" sequence, continually walking back and forth despite the player being within LOS. My decorator is set to attack target and abord is set to both. I just can't understand what I'm doing wrong at all. The only thing I can think of is if there's some issue with my line trace detection specifically with the LOS Decorator, because the EQS for both other tasks work perfectly. Everything works perfectly in fact, aside from the decorator interrupting each sequence. Any pointers would be appreciated. At this point Ive given up and moved on to other videos, but I worry that it's going to come up and bite me in future if I don't nail this bug now.

[@AliElZoheiry]

In your CanSeeTarget decorator, is the line trace hitting something? Try adding a print statement to see if it is

[@user-vd8sb8gb4t]

Use a branch in after the return node CanSeeTarget Decorator

Bro, I'm having the same issue. I even did the line trace debug and the player is seen which means that it is working.

[@AliElZoheiry]

In unreal engine you can write C++ code, so if you can create your models in C++ then you can integrate it with the engine code as a regular class, but it will require a good amount of knowledge on how unreal engine works in C++

Thank you for your comment! 🙏 In this case, using casts is essential and has no impact on memory since the actor we are casting to is already loaded in memory, thus casting has no impact on performance

This error is saying that you don't have a blackboard. Make sure you have a blackboard next to your behavior tree in your content browser (Also if you're on an older version of UE, you have to manually assign the blackboard to the behavior tree, otherwise this blackboard variable will be null)

[@Smyyytth]

@@AliElZoheiry I have a blackboard, I'm using it for all my keys. And I'm using the latest version of UE. The blackboard is next to the BT. But knowing what it means makes it a little easier to troubleshoot. Maybe I'll try to remake the blackboard! Thanks for your help.

[@xanderbroadbear5980]

I think that in your AI controller blueprint the cast to the BP_Enemy_Base is failing, and thats why the blackboard is none. For me it was failing because i had the weapon attached incorrectly in my BP_Enemy_Ranged .

[@buga125]

I just had this problem and I just figured it out too - for some reason only the damage event caused this error and I had another enemy spawned that I forgot about (as I was playing with this AI controller a bit and just left it stranded somewhere) and that was the one that was causing the errors as it didn't get any blackboard from the BT so if anyone has a similar problem - I recommend checking also if there are no other spawned enemies that hasn't been fully modified to fit this AI behavior. After deleting that other enemy, it all works without errors :)
