For anyone having issues with the WieldSword functionality, it's good to know that I didn't show how to edit it to include an animation, but it is the same as the UnWieldSword, so if you want to add that animation make sure to also include an event dispatcher (Call onWieldSword) from your enemy blueprint, and update the task to only Finish Execution when OnWieldSword is dispatched (Just like we did in the SheathSword from 40:45 to 44:20)

These are seriously the best tutorials I've come across. No fluff, great pacing, and even though they're over 40 minutes long each, I know they're worth watching bcz you do such a good job explaining everything, and it's not filled with useless information like modeling a character first, or animating something, straight to the point and topic of the tutorial. Thanks for all your hard work making these AI tutorials, they couldn't have come at a better time for me since I'm implementing a combat system right now. You've definitely earned a subscriber.

Hi Ali , im really excited about the series . Im just bum out that sometimes i dont understand your math, especially the Patrol Index. Im trying my best to understand it, had to crush my head. Hopefully ill knock some sense into my own brain :D

@AliElZoheiry

Жыл бұрын

Hey Danny, let me try to explain it simply. The patrol index is just the point on the spline that the enemy is currently on starting at 0 (meaning the first point) so when the enemy moves to the next point we need to add 1 to that index (so then the patrol index is equal to 1 which means the enemy is at the second point in the spline) then we need to check if we reached the end of the spline, by checking if the index is equal to the number of points in the spline (but minus 1 because we started at 0 not at 1) then if we reach the end we just start subtracting 1 from the patrol index instead of adding 1 (this we change the direction to be -1) and do the reverse once we reach point 0 on the spline again. Hope it makes more sense now

Great content so far! My AI has been severely lacking. And, these videos are just what I need. I'm wrapping up for the day. I've only had one issue that I cannot seem to figure out. When I press "1" the first time, everything works great, and I created an UnsheathSword Montage similar as you did, and spawn the sword using a Montage Notify as usual when working with Notifies. But, the Enemy will not turn to face the Player as it unsheathes the sword. It will unsheath, then turn to the Player everytime. I've tried playing around with different things, and I'm not quite sure what is going on. Other than that everything looks great. I've debugged the AI Behavior Tree, and it looks like it flashes by the BTT_FocusTarget(with AttackTarget as the Attack Target Key) and goes directly to the BTT_UnsheathSword I created under the BTD_IsWieldingSword Decorator. That is all within the first sequence. The numbers on the nodes look correct. I'm not sure why it is skipping the BTT_Focus Target Task though. EDIT: For now, I'd just added a Wait 0.5 Seconds Node to the middle of the sequence. So it will Focus wait half a second, then unsheath the sword. This gives the AI enough time to turn and face the player, even if directly behind the AI. Using 5.2.1, but don't think much has changed in this regard.

In the behavior tree tasks that you create you are casting to the enemy base class. Do you think it would be more efficient to either update the BBkey through the enemy blueprint by using "get ai controller>get blackboard>set blackboard value as..." OR would it be better in the behavior tree to cast only once and store the enemy reference instead of casting every created task?

@AliElZoheiry

Once we start adding the enemy AI interface, I won't be casting as often since I'll be calling interface functions, but in general, casting isn't a performance heavy operation, so you can cast on each tick, hundreds of times and it won't be a performance issue unless it's thousands of times per tick

I'm not really sure I understand the issue, but if it is regarding the decorator not succeeding/failing correctly, then I suggest checking the implementation of the decorator and seeing when it returns false/true.

In part 1 we built the "BP_Enemy_Base" code (pt 1: 37:00 - 41:07). But it looks like that code got replaced by completely new code, of unknown origin, appearing here in this Part 2 at 8:16. I've spent a week on this tutorial. I've redone this and part 1 a few times now, and I can't get it working. Here's how mine works: Press "1" the first time: Enemy just stops patrolling and stares at me. Press "1" twice: Enemy slides along his patrol zone and continually unsheaths Press "1" third time: Enemy slides, then finally runs and attacks me. Press "1" fourth time: Enemy sheaths a few times and returns to his Patrol Path; the sword never disappears. After tearing out most of my hair, I gave up and downloaded the project zip. When I open that project and play, the Enemy AI faces me, unsheathes, and then runs behind a wall, faces the wrong way, and swings at empty space a few times. Is there a way to get a project download at the point where the action makes sense at the end-point of this video?

Hey Heavenseek, so the enemy blueprint was not completely replaced with something else, as mentioned at 1:14, I just changed the WieldSword event and behavior tree task to include an animation and an event dispatcher, which I proceed to explain at 38:20. It sounds like your problem is likely with the wield sword event and behavior tree task, make sure that in the WieldSword event you dispatch OnWieldSword and in your task you bind to this event dispatcher and only call Finish Execute then, just like we did for the unwield task at 43:55

@@heavenseek Hey man, I found a bug in the engine that might be causing your issue. It happened to me today when I restarted the engine, I found that the Blackboard keys on the "BTT_MoveToIdealRange" in the tree got reset and I had to manually select them again. Meaning that I had to Change the "IdealRadius to be either the AttackRadius or the DefendRadius (depending on whether I'm attacking or strafing) and the AttackTarget set it to AttackTarget as well. Hope this helps

This is exactly what is happening to me. I followed the directions exactly and have gone back through them several times. I can't see where the discrepancy is. I'll take a look at Ali's suggestions here.

Excelent Video, I have a doubt, in my case my character when he appears on the map makes the animation of drawing his swords, but I want him to not move while he is doing it, so I put a wait at the beginning of the Passive State, it worked but then to advance point o'clock it is also expected, do you know how to make the wait only at the beginning and not repeat itself anymore, thank you.

@AliElZoheiry

If your character is doing an action and that action is triggered by a behavior tree task, then you shouldn't Finish the task execution until the action has ended, that's why I added the event dispatcher in the wield and sheath sword functions, to tell the task that the animation is over and you can move to the next node. This is what you should do as well, because a wait node won't work for all animations since they have different timings

Hey Ali, i was having an issue with reversing the sheathsword animation. the enemy would'nt play the montage if its reversed, but he was able to play it unreversed. i checked the BT. and when id swap to the attack state, it would just get stuck on wield weapon and he would'nt wieldSword. If i use it not reversed, functionally it works and hes able to spawn the weapon. Im not sure why that is, everything seems correct. Could it be the anim notify ? it works fine on the sheathsword animation, but should i do something else if i reverse the play rate of the animation ?

@AliElZoheiry

Hey Shino, not really sure what the issue is, but if the montage notify isn't being triggered in the reversed montage, try deleting the notify and adding it again, it often happens that notifies become null when you make changes to the montage after adding it

@Shino2213 I got stuck here to. My issue was, I had used the wrong method to reverse the animation. Check that you have changed the PLAY RATE by clicking the animation segment in the montage timeline Make sure you have not changed the RATE SCALE like I had! Plus reseting the also helped

Hey, not sure if this is addressed at some point but at the end of the last tutorial, the enemy snaps to the new direction it's moving in instantly.

You're very welcome. glad you're enjoying it and finding it useful so far. Regarding the enemy rotation speed, if your enemy is not rotating smoothly, then this is likely due to the "rotation speed" variable on the characterMovement component in your pawn class, try adjusting that and seeing if it helps

@@driftmirror This is the answer. Also, you can still set the rotation speed on event begin play from the character movement component - thinking about it though I could just change the default. One thing I do is that when my enemy attacks, I set the rotation speed down to like 30-50 from the montage exit pin, which gives the attack some give without glueing to the player, like if you're running near an enemy and it attempts a claw attack or something, and then on montage complete or interrupted pin, i set back to my standard rotation speed of 120. Think about smoothing on your blend spaces too. i had an awful animation jank on a creature when it would close the distance with the player, then initiate attack montage and the legs would just move to quickly. It was essentially the blendspace speed approaching 0 (idle) that I forgot to apply any smoothing to. So I set to one second and it's a relatively smooth transition now. I'm really happy how Ali's tutorials are working in my prototype.

this episode ruined it for me bro, everything was going amazing until this episode, about 3/4ths through the video things began not working right with the enemy, after the whole sheath thing. i followed exactly and went over things three times to ensure no node is incorrectly done, i can see a LOT of others had issues here too, i went on after this video and the other videos are good but this one is the issue one, i know you've defended your edits and actions in the comments but this video seriously desrves a re-do, but go over things completely as you do them, this is the ONE video hurting this entire playlist.. i found this video on reddit, on the UE sub there was about a dozen users who praised the tutorial but warned against part 2 of it, which i ignored because i assumed that i could figure out where they had issues, looks like it got me too, this video is mostly good but had a vital error keeping it from being as polished as your other vids, please re do it bro.

The reason I wrote this comment, and the reason you might be having issues, is that event dispatchers, and behaviour trees are a new way of working for most of you, so it can be confusing, but I assure you, the content itself is tried and tested and works perfectly, if you are having issues, feel free to join the Discord server and we have a youtube-help channel there where you can ask your question, provide details, then I or someone else can help you there.

Hey Dominic, the functionality of pressing 1 to get to the enemy to follow you is just for testing, but if it's not working, that probably means you have another issue with the enemy behaviour that will still occur even if you skip that part. Most people who were facing this issue were having different bugs. Some related to the event dispatcher not being called or binding incorrectly, some had bugs in the behaviour tree, etc.. so it could be anything.

One possible solution to this problem could be related to the event dispatchers and binding in the behavior tree task. Make sure that the event dispatcher for when the sheath sword event has finished is firing correctly and that you are binding to it correctly in the behavior tree task. Additionally, you can debug your code to narrow down the problem. You can check what's happening step by step to identify where the issue might be occurring. If you still haven't found a solution, you can also refer to my bug fixing video for some tips on troubleshooting bugs.

Hey there! It depends on how you implement the death logic. If you unpossess the pawn from the controller, then you should stop the logic of the behavior tree anyway, so it doesn't matter if there is an isValid check. Generally, if you're controlled pawn is ever inValid, then that means you have something else wrong in your implementation, because that case should never occur

I cannot get the NPC to move to spline points. I'm not sure where the breakdown is because the AI debug says it's the current task, but the NPC doesn't move. I went back through the tutorial twice and I don't know what I'm missing. The only thing that I've changed from the original tutorial is I promoted the Acceptance Distance to an exposed variable on the AI Move To inside the BTT_MoveAlongPatrolPath task so I could modify it directly from the main behavior tree, and replaced the Scene Root Actor with a custom sprite billboard that is easier to find among all my world objects - I'm still able to assign the BP_PatrolSpline actor to the NPC, so the reference isn't broken as far as I can tell, and it's not abandoning the task when I put it on a selector to choose between patrolling and chasing, so I have no idea why it won't move. I haven't gone beyond timestamp 15:25 because AFAIK the implementation is broken somehow and it shouldn't be an issue with UE 5.3 - does anyone have any helpful advice for what I could be missing? Any help is appreciated.

Hey, I can't really tell what your bug is just from this description, so I suggest that you add breakpoints or print statements in the patrolPath to see if it's printing the values you expect, that will help narrow down the problem.

This is probably a specific problem I had but an easy fix anyway, my set focus wasn't working so the AI didn't focus on the player before drawing the sword, then I found out that I set the AI rotation settings to Orient Rotation to Movement instead of Used Controller desired Rotation.

Hey Erik, so the "PatrolRoute" variable we created in the enemy class should "Instance editable", which means you need to click on the "eye" icon next to the variable name in your blueprint, or make sure the checkbox for "Instance editable" is checked. Then when you select on your enemy in the World. You can search for that variable in the details panel and assign it the value of your patrol route (which also has to be placed in the world first)
