Awesome tutorial as always. One thing I got stuck on for awhile that is not mentioned but done very quickly is at 31:37 he sets ideal range and attack target variables to instance editable which allows you to change the blackboard key values in the behavior tree. Took me a while to figure out why I was unable to change those values so I figured I'd mention it in case anyone else has the same problem.

This, truly, is a fantastic series. You're explanation is so well thought out and easy to follow, especially for someone like me who is just getting started.

@Moridagnir.G.P 2 месяца назад

yet again great video! Something that people can do is add in a Tester Actor, which I added in a bool to allow easy testing, just toggle the instance editable. Then GetActorOfClass TesterActor, grab the bool value for Testing, then use that in a branch to either print and display the EQS markers, or to real AIC to player. Very simple but stops you having to reopen the file and reconfig it every time. **EDIT** This is for inside the EQS_Context_AttackTarget class :)

@g0dk1ller123 10 месяцев назад

I don't know if I missed something in the video or if this is later adressed but I was constantly getting a runtime error: "Blueprint Runtime Error: "Accessed None trying to read property CallFunc_GetBlackboardValueAsActor_ReturnValue". Node: Return Node Graph: PerformConditionCheckAI Function: Perform Condition Check AI Blueprint: BTD_IsWithinIdealRange" in the decorator function. I found out this was happening because the enemy at the beggining wasn't seeing me so the value of Attack Target would be null when the node was being called thus printing out the above error constantly. I fixed it by simply adding an Is Valid node to determine if the value of the Attack Target variable is a valid one or not and that pretty much fixed the issue. Amazing series by the way! I've been learning a lot regarding AI in Unreal Engine and this has been especially helpful for me since I'm changing engines from Unity (you you probably know why 😅) .

@AliElZoheiry 10 месяцев назад

Hey, glad you’re finding this series useful so far, and indeed I have an idea why you’re switching from Unity :D I’m not sure why you’re facing the null pointer, since the AttackTarget should always be valid if the enemy is in an attacking state, but nonetheless it’s always good to add validation checks anyway

@kellowattentertainment 11 месяцев назад

Alright, so I ended up fixing the issue. In the video, you mentioned that the context offset should be zero because it doesn't do anything. However, when I ran the debugger with the Apostrophe key and Numpad 3 on the keyboard, I realized that with the context offset at zero, for some reason the engine was showing the AI that the best place to be is where he was standing already which was right before the player, so I added 200 to the context offset, and now the engine was showing the player that the best place to be is behind the wall so the AI now goes behind the wall when he sees the player. Issue resolved. Still, I wouldn't have learned any of this without your tutorials, so you are awesome. Thank you.

@AliElZoheiry 11 месяцев назад

Great to hear that it's fixed! For reference, the context height adds to the z axis of the context of your query, and item height adds to the z axis of the point which the trace is being drawn towards

@unrealdevop 4 месяца назад

Bro, your content is hands down the best Ai content available. Very well explained, and very well executed. Thanks for the videos Note: You can also setup a 'Blueprint Interface' to pass that 'actor variable' and have that variable be 'instance editable' so that you can simple select the targets you want from that instance of the Test Pawn and at least for me it works. (Seems to be an update bug where you have to change it back to Querier and then back to your custom one for it to update in the viewport and show those points)

I am a beginner. You have led the lectures well with the learners in mind so that even beginners can easily follow lectures 1 to 3. While listening to your lectures, I thought you made really good tutorial lectures. However, I was a little disappointed that the animation settings part of this lecture was missing. I understand that it is missing because it is an AI lecture. But I liked learning by following the directions you taught. I watched a lot of completed projects and other paid lectures, but even if I received a completed project, it was often of no use because I didn't know how it was created. I wanted to understand the learning process one by one and assemble it, but this lecture left something to be desired. You can sponsor me and receive the completed project, but I am so sorry that I have to move on from the project that I am very attached to and move on to the completed project, which I have been following through your lectures and taking notes to help me understand. I think even beginners like me will learn a lot if you proceed without any omitted parts from next time. I am writing this from the perspective of a beginner who is learning. Thank you for creating a great lecture. You've done a great job up to this point :) Moving on to the next video :D Thank you for the tutorial!

Just FYI I spent hours on this EQS find cover on UE 5.4.. while the testing pawn was fine with the query my IA didn't like it, just stayed there on starting point. all fixed after i set item and context offset to 0. in the end i resolved with '60' which i think is a good compromise for now.

Hi Ali. Firstly, thank you for being so generous with your time and sharing your knowledge in such an easy to understand, and yet very complete way. As many others have stated, these tutorials are well thought-out, and your teaching style is thorough and easy to follow. I am working through this series with a view to two types of enemies... one is a bipedal enemy, but the other is a flying enemy (like an attack drone). Navmesh does not seem to work well with flying enemies. Is this something you will be covering in future? Or could i encourage you to develop some content for flying enemies? 😉

@crs11becausecrs10wastaken Месяц назад

Great series man, delving into areas of the engine I had yet touched upon. One thing that did break for me, is when I deleted the move to actor node in the attack sequence and replaced it with move to ideal range node, the sequence breaks. It quickly skips over the move to ideal range node as if the enemy AI is already in the attack radious of 150 and does the attack montage, no matter what distance it is from my character. I've gone over this video five times now, step by step, and this problem continues to persist.

@AliElZoheiry Месяц назад

If it skips over the node instead of failing on it, that means the node is succeeding, so if it isn't doing the expected behavior, you might want to see why it reaches the success function without moving

@crs11becausecrs10wastaken Месяц назад

@@AliElZoheiry After two days of exhaustingly going over my node structure, I just found the issue. On the decorator, the execution line was coming out of the execution out pin of the node instead of the success out pin of the node. >.< Sometimes blueprint muscle memory works against you.

@Zoykzmc 6 месяцев назад

Wow, this tutorial is great! One question, how would I go about having the strafe always be in one direction? Since both points would be at equal distance is there a way to prefer one side?

@AliElZoheiry 6 месяцев назад

Thank you for the video! I have a question at 29:26, is it okay if I don't connect anything to the 'target' in the 'Get Ideal Range' function?

@AliElZoheiry Месяц назад

Hey there! You need to connect the correct actor to the Target of the "GetIdealRange" function, because if you don't connect anything it will use "Self" which is a reference to the class you are currently in (Which is the AIC_EnemyBase) so you will be calling "GetIdealRange" on the AI controlller that doesn't implement the interface, thus will always return 'null'

Hey just wanted to say great video! Your videos have been of tremendous help to me. I just had one question for the find cover eqs. In my game I do shots from the player as a line trace on the visibility channel and when i try to use the find cover eqs on an ai that is supposed to be shot by the player. The ai chooses the place right behind himself which is the closest out of sight spot. Do you have any workarounds for this? Thank you for everything. Keep up the good work!

@AliElZoheiry 4 месяца назад

Hey! Thank you for the kind words and I'm glad my videos have been helpful to you. What I understand is that you're trying to have the enemy walk a certain path to go behind the player (obviously by not walking infront of the player), that you can't do with EQS, because EQS can only give you the location where you need to go (and you can get a location behind the player easily using the "dot test" in the EQS), but then to get the enemy to take a specific path to get there, then you need to play around with custom navigation, or dynamic nav mesh modifiers

@Arctan95 Месяц назад

@41:30 interestingly, the behaviour I'm seeing is the enemy runs up, attacks and THEN begins strafing. As far as I can tell our networks are the same and logically I can see why mine is doing that, I don't understand why your unit would start strafing before the end of the attack player sequence? There's no abort that would affect it and the move to ideal range eventually returns success, the only reason it eventually moves onto the strafe is because of the cooldown right? Which returns false, dropping us out of the AttackPlayer Sequence. Why is yours failing right after the custom move to node we wrote?

@AliElZoheiry 28 дней назад

The only thing I can think of is the cooldown node working differently for different versions of Unreal. So if you're not on 5.2, that may be a reason

Is there an option to do something on EQS fail (when there are no acceptable points) ?

@muntasirdawlut 8 месяцев назад

For Those whose Enemy is not going to hide at the 50:00 I've found out that the issue is the line trace channel in the EQS_FIndCover, Click on the Trace and you will see channel, normally by default it's selecting VISIBILITY by default. Now click on you enemy and ignore the visibility channel Under collision and everything should work, normally if you have an enemy the visibility channel is not much of a use because you will create custom trace channel to make your enemy more receptive to various trace that may occur in the game such as getting Hits etc. hope this helps Someone facing this issue

@Kykyhaaa Месяц назад

Thanks for your video. But I have some spoblem. I don't know why, but my enemy don't whant to hide if I choose test trase as contex_AttackTarget. It's what you chose in the video, but for me working only Contex_Querier.

@AliElZoheiry Месяц назад

We choose the attack Target because we are doing a trace from the querier (the enemy) to the attack target (the player) and checking if we hit anything in between. If we do, that means there is something between the enemy and the player and we can hide there. If you do from the querier to the querier, then you are doing a trace from yourself to yourself, which as you can tell, doesn't do much. if setting AttackTarget is not working, then I suggest looking at the "Collision settings" for both the player and enemy "Mesh", they should both "Ignore" the "Visibility" channel. Otherwise the line trace will think that hitting a player is a hiding spot

@AliElZoheiry Год назад

Very interesting idea, I know how to implement that indeed, it's not simple to get it to look good because it requires aligned animations from both the player and the enemy, but the functionality itself is not very difficult to implement, I'll consider it for sure ;)

@AliElZoheiry 3 месяца назад

Hey there, thanks for your comment! To properly debug your issue, I recommend having the behavior tree open while the game is running and see if it's following the branches as you'd expect, and where it goes wrong. I also recommend adding lots of print statements and break points to follow the execution of the code. That's the only way to figure out what's happening. I have a video on how to fix bugs on my channel if you want to learn more about the process of finding and fixing bugs

@HandsOnKnowledge 10 месяцев назад

I have run into an issue and can't seem to solve it maybe you can help? I added the AttackRadius and DefendRadius in blackboard and the value was being set by the interface just like you showed but what ends up happening is that my enemy character never seems to leave the "isWithinIdealRange" Sequence and gets stuck there and then switches between Attack and isWithinIdealRange sequence and never seems to get to Strafing? Could you help me with that?

@HandsOnKnowledge 10 месяцев назад

Wow as soon as I posted this comment I went back to look at the code while the game is paused and on the bottom right hand side you can see the values of the blackboard variables and I saw AttackRadius and DefendRadius were both 0 then I went to AIC_Enemy_Base and saw that I forgot to connect the SetValueAsFloat functions after GetIdealRange function, silly me :)

@AliElZoheiry 4 месяца назад

If you're trying to have the enemy walk a certain path to go behind the player (obviously by not walking in front of the player), that you can't do with EQS, because EQS can only give you the location where you need to go (and you can get a location behind the player easily using the "dot test" in the EQS), but then to get the enemy to take a specific path to get there, then you need to play around with custom navigation, or dynamic nav mesh modifiers

I honestly haven't tried 5.4 yet, so I am not aware of any specific issues there. But it could also be the EQS itself failing to find a valid point so the enemy freezes, that's a common issue if the EQS was setup incorrectly. Specifically if the grid is being generated around the incorrect actor (e.g that querier instead of the attack target, or vice versa)

Hey! As always an amazing tutorial and I've been pretty much able to follow through with some bumps in the way as I don't use the default assets from TP template :) I have a weird problem though with the eqs - specifically with the AI MoveTo task, but I wonder if it's not the animation blueprint setup that's wrong here. The enemy strafes correctly to each point, but the BT seems to linger on the MoveTo task for about 5 seconds after the enemy reaches the point, which causes the enemy to stand in one place for 5 seconds and only then go to the next point. I noticed that in the animation blueprint the Speed value goes down to 0 when the enemy reaches the point so I thought maybe it was a problem with the Idle animation being too long, but I changed this idle animation to be one frame only and it still happens. Any ideas on what to check so the enemy doesn't stop? The MoveTo shouldn't wait for that long until it loops back to the beginning I guess? I fixed it temporarily with a Time limit on the MoveTo task (5 sec), but I don't know if this is not going to break something else and I feel like it will :) Appreciate the content tho, I'm learning a lot!

@AliElZoheiry 2 месяца назад

Hey there! Thank you for the feedback and I'm glad to hear you've largely been able to follow the tutorial. The issue you are mentioning is quite strange, because the MoveTo task completes when the enemy reaches their destination, so if they stand still for 5 seconds and then completes, it means that they were already at the destination 5 seconds ago. So unless there is a manual delay in the MoveTo task before calling Finish Execute in the BT Task, then I don't really know what's happening 😅 and indeed a manual time limit is definitely gonna break later on

Thank you for your great video. I have one question, if the AI has its own base, how give more EQS scores to the direction toward base in case AI need to retreat, and give a lower score to the opposite side of the enemy base. In summary, I would like to know how to measure scores based on something outside the radius of EQS. How is that possible?

@AliElZoheiry 7 месяцев назад

You're welcome, glad you liked it. If you just want to have an EQS that moves in the direction closer to another actor then instead of generating a grid of points, you can generate points around specific actor types, you'll find that as an option in the EQS called ActorsOfClass. But that just gives you the location of these specific actors, what you want is to move closer to the base and not further away Unfortunately you can't combine the information from 2 EQS queries without some manual work in the middle, but what you can do is simply have the actor face the direction you want them to go, and then generate points Infront of them only

@morphe1467 7 месяцев назад
