I did everything step by step, I'm not actually sure where I went wrong. The NPC didn't move when I hit play, it wouldn't move, I changed around the wait time and still didn't work. It was probably just something I did. Your tutorial is great though!
On UE5 the character will not animate following this tutorial unless you enable “Use acceleration for paths” under the character movement component of the AI BP
Hi, my AI character asumes t-pose sand slides around. I tried this,but all it did was to drop the character into its idle pose but still slides around when changing location. Seems to be ignoring the state machine. If i connect the same character to axis inputs, it works fine. Hope you can help, cheers
I gotta say, you're extremely good at getting information across. Straight to the point teaching style, friendly tone and no cringey fluff. Keep it up mate.
While I understand this is a 4 year old video, its a great resource. If your NPC is NOT moving go look back at your custom task, look specifically at "GetRandomLocationInNavagiableRadius" function, you have to connect the "Whte" EXEC path through that (the one in the video does NOT have the Exec paths - so he does not have to connect his).
Important: In the beginning when you add your skeletal mesh, be sure to rotate it so the character’s face is pointing the same direction as the blue arrow. The blue arrow represents the direction that is considered forward for the character, so when it moves it will rotate the character so that blue arrow is pointed toward where it’s going accordingly. The animation is triggered regardless along with moving the character, so if you don’t rotate the skeletal mesh it will have your character appearing to run sideways or backward and look unnatural. The tutorial creator does do this, but doesn’t call it out loud that he is doing it, so if you’re following more off what he is saying like I was this would be an easy mistake to make and then be confused why your character doesn’t seem to be moving correctly. Hope this helps avoid some frustration.
I had this issue, thanks for the advice! I'll just piggy back off it and add that if the NPC isn't running on the ground, you should also check to see if the mesh is properly placed within the collision cylinder. My NPC was running sideways about a foot off the ground at first, but now it's much more natural looking.
I'm actually pleasantly surprised. Its hard to find clear and well done tutorials for UE. never looked at the AI but I'm entering a one man game jam so figured was about time ! Very useful ! Subbed :)
For the past two days, I've been re-watching this video and reviewing my work, trying to figure out how I could possibly have everything exactly the same, but still not have my AI working. It wasn't until I checked out the Unreal tutorial for Behavior Trees for this same movement that I noticed I had "FindRandomLocation," "MoveTo," and "Wait" all coming out of the Selector node instead of the sequence node lol. Definitely the biggest and longest brainfart I've had ever!
@@mwilsonjr92 I made that comment hoping it would save others in the same boat XD It boosted my confidence a bit though. Really reaffirmed that 95% of the times I encounter issues, it's just me doing something wrong, and mistakes are fixable, usually lol. Happy deving!
I really appreciate you taking the time to make this video. It's quick and ACTUALLY a tutorial rather than most tutorials that tell you what to do and not WHY you are doing it. Thank you!
For Everybody having problems with the NPC not moving in newer UE version (or whichever versions), and has already tried every other solution in the comments. Here it is: Your NPC needs to be a character class not a pawn, in order to move.
TEMP FIX!!! In UE5, if your NPC is just sliding without any animation, go to that specific anim class (Eg- ABP_Many) -> Event Graph -> Look for Set Should Move to..(Comment). The first component inside is to get the current acceleration from movement component, disconnect this one. From the 'VARIABLES' tab on the left side -> under the Essential Moving Data, drag and drop 'Velocity' -> Connect this one, to node where the current acceleration was connected to. Compile and Save. PS : This is a temp fix that I found working for me, due to this change, may be something will break in the future.
I solved this issue by enabling "Use acceleration for paths" under the character movement component of the AI BP, then duplicated the animation blueprint and changed the cast after the initialization from ThirdPerson BP to the npc one.
Can someone tell me possibly why when I press play after setting up find random location my BP_Mannequin just stands there? He doesn't walk anywhere. I'm on UE5 - Does this mean there's something else I have to do?
followed this step by step, and literally nothing happens, dont know whats going wrong and im a complete beginner so debugging it is completely out of the question, otherwise good video
so i tried this with a custom model but it didn't work. i then restarted and copied the tutorial step for step but the AI still didn't move. any suggestions.
This is me just being dumb but for anyone it might help, when you create the vector key make sure in the behvaior tree the find random location is set to "target location" (vector key) and not self actor. Very good tutorial though, all these videos are super helpful!
Great tutorial series, very clear with good explanations and no fluff. Thank you. In my 'follow along' project, the behaviour tree seems to ignore the animation blueprint as my AI character just assumes T-Pose and slides around. Have you come across this or know the solution? Much obliged.
TH-cam should add the option which allows u to hit like more than once , like clapping On "Medium" . Great Video, content that didn't find even at UE youtube channel
At 4:06 for anyone who is getting an error "This blueprint (self) is not a AIController, therefore ' Target ' must have a connection.", drag off of the target node and say 'get AI controller'. fixed the error for me. EDIT: This breaks when clicking play. Does anyone know how I can fix this as it wasn't an issue in earlier versions of Unreal Engine but it seems like it is one now More info: The event graph of NPC and NPC_AI sync. So whatever I add to the NPC_AI graph also gets added to the NPC graph. Because of this, I am not getting a compiler error in the NPC_AI graph, but instead in the NPC graph. It doesn't like that Target=self.
I found this was because I was using an enemy spawner. I was using a 'Spawn Actor from class' node instead of a 'Spawn AI from class' node. Dunno if this will also fix it for you.
Great video. I learned a lot. Very clear and to the point. I just came from the official unreal engine AI tutorial. It was so poorly done I couldn’t watch it all (cringe) so this was a welcome sight.
i followed the instructions almost exactly with just a few minor tweaks to the customizable stuff that shouldn't effect how the AI functions overall. I can't exactly figure out what went wrong, so does anyone know of any common mistakes i could have made that i could look into?
Great series, learned a lot. However, I don't use Blueprints so I converted everything into C++ and started an AI series of my own based on what's here.
I know this is an old tutorial but I had a question. If I wanted two different NPCs (one that roams and chases and another that patrols and chases). I'm having trouble "editing" what you showed us up to Part 6 and creating the Roam/Chase without recreating it all. Is there an easy way to do this?
IF YOUR USING DEFAULY ANIMATIONS AND THE WALKING ANIMATION IS NOT WORKING: Check the event graph in AnimBP, look for the "Should Move" variable. Ensure ONLY "Ground Speed" and Greater Than are connected to the Set Should Move boolean. Disconnect the "AND" node from the Greater Than node, and it should work :)
BUT FOR ALL OTHER ANIMATIONS I have no fucking idea and it's really slowing me down. This default animation fix works up until episode 8 when he introduces an attack animation which is built for the UE4 manny and not UE5. I would very much like to know how to import other animations for example the Paragon Characters. They all just slide in idle.
Tried this on animal after I used the third person setup all the code from the event graph does not work Like I said on some one else channel looks like 99% of AI tutorials that every one is using has a premade third person they are using that has all the code setup before hand as in idle walk run jump sure would be nice if some one made a in-depth Ai Behavior Tree for animals. But from what I seen no one knows how every one what zombie or shooting game sad no one make a good animal videos any more.
Hi, I Managed To Get Into The Debug Mode :D And I Have A Question, Is The NavMeshBoundVolume Connected To The NPC And If Not How I Do Diffrent NavMeshBound.... On Diffrent Types Of NPC's ? If The Answer Is Difficult I Understand Not To Reply.
My "Set Blackboard Value and Vector" doesn't work. No matter what I put in the Vector node it returns some godawful 10 digit number when I check with a print. Using 5.0
I've just made anims of my character and looking for some AI tutorial i Came to these absolut gold videos. But just realize i got all the characters movement base in root motion animations. If I implement a quick new anim blueprint withut RM anims, everything goes fine. Do you know how can i make an AI, and its behavior a BB, keeping the RM anims?
Hey, could somebody help me with my issue? I was following a tutorial about AI and I followed all the steps correctly, but the animation doesn't play, although the AI does move. If someone can help me, feel free to PM me. I'm thankful for everyone, getting confused with the whole UE thingy. Thanks in advance. 🙂
If I wanted an NPC to move about, and be spoken two using the Dialogue Tree how would I do that. As currently when the Dialogue Tree ends the Logic is killed in the AI Controller. But I only want the Logic to be killed for the dialogue tree not the Behavior Tree
So how would I go about using this for a custom character? Obviously I'm not going to make a game using the mannequins, and have my own characters? I tried with my own but it just slides around in it's idle position.
Done everything but the NPC won't move EDIT. Sorted, i had the FindRandomLocation, Move To and Wait coming off Selector not sequence. Now i need to find out how to get him upstairs as the green nav mesh doesnt go from bottom of the stairs to the top.
can someone maybe help me? i am trying to use this for my 3d Sidescroller project. and i also made sure that everything is right connected! pls help me! thank you for the answer/s
Nice, but my character doesnt move an inch.. Just standing. Why is he not moving? what can i do about it. i want to break something. Oh i got it, When in BT, the task was not base but the wrong self made task.
Hi! I'm using this on the NPC blueprint made with the dialogue tutorials as a base for this one. I can't figure out how to make the npc stop when I talk to him. I don't know if that should be in the behaviour tree of the npc blueprint? Can someone give me pointers? Thanks
i have a problem and hope you can make a turorial on that i followed you hole tut on this but now when the AI is killed the controller is not and it will still attack you i did use the stop logic but that is Stopping BT but not Functions
Ai behaviour trees are easy... You basically need three tasks... Loiter or guard or patrol... Condition check player is visible or in range or alerted somehow... Move to player... Condition check, in range... Attack player... Condition check, reasons you can't attack...
For anyone encountering an issue where the AI refuses to move and none of the suggestions so far work, this might: When adding a Nav Mesh it also adds a Recast Nav Mesh, but when deleting a Nav Mesh it does not delete the Recast. When adding a new Nav Mesh it does not replace the existing Recast which causes the navigation to fail somehow and without really feeding this back to the user. Delete both the Nav Mesh and the Recast Nav Mesh, then add a new Nav Mesh and it should recreate a new Recast Nav Mesh for it. Hopefully this will get your AI moving about again.
I figured it out! When creating the random location at 11:00 your radius must be large enough AND the "Acceptanble Radius" Entry (Behaviour Tree "Move To" Node) can't be too big, otherwise the AI doesn't have enough distance in total. Thanks for the tutorial!
Great series. I'm following along in UE5, but I can't figure out how to get the NPC to change animations. I have the same mesh and animbp set as the original character but for whatever reason it won't transition. The NPC just slides around in the idle animation.
@@magicgamestech9448 could you explain further? Not sure what you mean by this, I am in the BP rn and I see ShouldMove and Groundspeed but unsure how to proceed

if i wanted to say that the NPC has to move to a specific point how do i do that? great tutorial btw
here go again... It's my 4 time here making this project hahaha i love this series
For anyone encountering an issue where the AI refuses to move and none of the suggestions so far work, this might:
When adding a Nav Mesh it also adds a Recast Nav Mesh, but when deleting a Nav Mesh it does not delete the Recast. When adding a new Nav Mesh it does not replace the existing Recast which causes the navigation to fail somehow and without really feeding this back to the user. Delete both the Nav Mesh and the Recast Nav Mesh, then add a new Nav Mesh and it should recreate a new Recast Nav Mesh for it. Hopefully this will get your AI moving about again.
I tried that and it still doesn't work unfortunately...
I use 4.25 and did everything exactly like in the tutorial
I figured it out! When creating the random location at 11:00 your radius must be large enough AND the "Acceptanble Radius" Entry (Behaviour Tree "Move To" Node) can't be too big, otherwise the AI doesn't have enough distance in total.
Thanks for the tutorial!

Same here, just Idle
What do I do I can find the event execute ai in my blueprint?
Great series. I'm following along in UE5, but I can't figure out how to get the NPC to change animations. I have the same mesh and animbp set as the original character but for whatever reason it won't transition. The NPC just slides around in the idle animation.
Found the issue. The AnimBP includes a check for input before setting the "ShouldMove" variable. Eliminate all but the groundspeed check and it works.
@@codytaylor2220 Thank you. I had run into the same issue.
@@magicgamestech9448 could you explain further? Not sure what you mean by this, I am in the BP rn and I see ShouldMove and Groundspeed but unsure how to proceed
NVM FIGURED IT OUT YAY THANK YOU
