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)

@djtc2093 8 месяцев назад

When you say "update the task" - which task or do you mean create a new task for equiping it?

@AliElZoheiry 8 месяцев назад

@@djtc2093 here I'm referring to the wieldSword task in the behaviour tree, because a lot of people had issues with this, and almost everyone forgot to call finish task (with success true) ONLY when the onWieldSword event is dispatched

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.

Im a complete noob and managed to follow this great (yet complexed) tutorial.. I kept leaving comments asking for help but then would follow the logic from what I asked and debug.. Then comment again with a new problem and delete as it changed aha. This is my final comment to say thank you.. Most my issues were to do with leaving a box unchecked or not connecting a pin for example I hadnt connected WeildSword to execute Bind event in the BTT_weildSword and in Sheathe sword so the BT wasn't finishing the task and getting stuck haha.. Having the comments to read through definitely helped me to fill in gaps on parts I had missed or you had done outside of the edit. Thanks for another great tutorial. Took me about 4 hrs as a noob to troubleshoot my mistakes :)

@DannyshRosli Год назад

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 Год назад

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

Thank you teacher Ali. Like part 1 your tutorial are very detail moreover your teaching and how you explain are really amazing. I also consider WieldSword function that didn't show in video as homework. Even now I cant count the spline point and don't know why it need to -1. The Spline point function are the last thing that I cant understand. Also it took me nearly 2 month to understand overall how the function operate, That make me realized how I lack of the foundation [Gonna cry in corner]

@DaviesMurphy Месяц назад

for example you have 10 spline point in your patrol spline point index 0 = spline point 1 ... ... ... spline point index 9 = spline point 10 index as defaulf start 0 but your point of number going 1 , 2 , 3...

@jarofpickles1246 9 месяцев назад

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 9 месяцев назад

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

For anyone having issues about being stuck in A state of flip-flop, hence not being able to change states. The problem might be the keyboard key. You can try using the enhanced input system. I first had a problem with the "Tab" button, but when I used it with the enhanced input actions, the problem was solved.

@Darryd 5 месяцев назад

Just out of curiosity, I'm just trying to make a simple Souls-Like Boss fight, I have the basics for the AI BT you've shown in the 1st episode, I was wondering what videos in order I could watch to get to the final 3 videos without missing anything important. For reference the character I'm following with is the boss I just don't need him patrolling/ hiding to get health if that makes sense? Love the series though and will definitely be coming back to learn more soon! 😄

@AliElZoheiry 5 месяцев назад

Hey Darryd, not sure I can tell you which videos to skip because the entire series is built sequentially, so there might be a slight change I make in one video that is used in a later one. What you can do though is check the "chapters" that are timestamped in each video, and they will give you an idea on the contents of that video, then decide whether to skip it or not

@theindiegamedude 11 месяцев назад

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.

@AliElZoheiry 11 месяцев назад

Thank you! Glad you've been enjoying the content If your AI is taking a long time to turn it could be the rotation speed of the enemy character is slow. If you're not using the default manny character and default settings, make sure to match it to the default manny settings for rotation speed and see if it helps

@theindiegamedude 11 месяцев назад

@AliElZoheiry - Thanks for the tip! I was actually thinking the same thing when I woke up this morning. Oftentimes, I wind up waking up with a proper solution XD Just got in from some morning endurance cycling. I'm going to get going on my projects in a half hour. And, this will be the first thing I test. Adjusting the turning/rotation speed on the ai mesh.

@Dominicn123 7 месяцев назад

hey man, did you figure it out? i'm having the exact same issue as you and i don't think it's the rotation speed

@theindiegamedude 7 месяцев назад

@@Dominicn123 - Sorry. I never did figure out the issue with the enemy not facing the player. I just left in the Wait half a second node to the AI Tree which I mentioned above. At this point I think I'm running off a copy of one of Alizoh's source files I downloaded a while back. I didn't think of looking for the change in the source for that particular issue. When I downloaded the source project, and started working off of that.

@kristopherjones5991 Месяц назад

Thanks for these awesome tutorials! I do have one issue with the Blackboard Decorator that is on the CombatState Selector. With it on, the enemy only runs the PassiveState side of the BT. With it off, the enemy will try to move to AttackTarget, but slingshots around the area never actually reaching the player. I don't know what the issue is, but any insight would be much appreciated.

@AliElZoheiry Месяц назад

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.

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 Месяц назад

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

In the tasks should you have an is valid off of controlled pawn? In my case I'm going to have a bunch of zombies. COD zombies style. And in my prototype (where I just used blueprints instead of behavior trees) I'd get all kinds of errors when they died unless I put is valid like everywhere lol

@AliElZoheiry Месяц назад

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

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 Год назад

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

I don't seem to figure out the problem! Can you kindly help?

@AliElZoheiry 2 месяца назад

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 Ali, i've been really enjoying your lessons on this as i've been trying to do this whole playlist, everything was amazing up until about 70% through this video when it came to flip flopping between hitting the '1' key... i can see many others are having issues as well. i've tried a few fixes and i just can't figure out where the issues are, i've thoroughly scanned the nodes to make sure they're all connected exactly as yours as well, they are good. but could we skip this portion where we press the 1 key, and be good? because in the following videos we're setting up the ai to act independently, so i don't see for there to be any need to set up my ai with the 1 key, would i be able to continue and be good if i skiped the last portion of this video? because we won't be using it later right?

@AliElZoheiry 7 месяцев назад

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.

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.

Do we make a Patrol Route for each Enemy? If we want say 5 enemies walking around in different areas? Also can you have 2 npcs on same Patrol route?

@AliElZoheiry 10 месяцев назад

Right now, since the Patrol index is stored in the patrol route itself, then we can only have 1 enemy per patrol route. Otherwise if we assign 2 enemies to the same route, then when one enemy increments the index, the other will do the same as well. To fix that, you can just store the Patrol index on the enemy itself instead of in the patrol route, then you can have multiple enemies on the same patrol route

@AliElZoheiry 8 месяцев назад

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 8 месяцев назад

@@AliElZoheiry I had to turn off "Use Controller Rotation Yaw" checkbox for it to turn smoothly. It wasn't respecting the rotation rate at all initially.

@dreambadger 7 месяцев назад

@@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.

@AliElZoheiry 9 месяцев назад

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)

@AliElZoheiry 2 месяца назад

The AI stops because the MoveTo task finishes and there is a slight delay till the next one (but it definitely shouldn't be 0.1 -0.2 seconds, more like 0.05) if you are experiencing a longer stop that what I have in my example, try playing around the the deceleration values on the characterMovement component (things like deceleration speed, ground friction, acceleration speed, etc..) If you want it to be completely smooth, then you'll have to start the next MoveTo task before the enemy reaches the next point on the spline, meaning that you have to check when the enemy is "almost" at the point, and then start to move to the next one
