Unreal Engine 4 - AI Roam

In this video I show you how to create a basic AI that roams around. We will work on making this in a Behavior Tree at a later date.

I'm not a native english speaker, but this tutorial is so amazing and easy to follow. Thank you so much!

[@DonMatek]

Cool stuff, took me a while to figure out how to make him move only along one axis for my side scroller learning project. Edit: After some hours of playing with my scripts I managed to set my bot to randomly move across Y axis only (I'm running a side scroller) and AI encounters(hits) another AI or Player it will run away in opposite direction. After that with some slight delay it will resume random moving. I'm really starting to get the hang on this, you tutorials are very helpfull so thank you and don't stop uploading! :)

[@swervbotArchive]

Really easy to follow! Thanks so much!

[@andrelouvier]

Thanks for the tutorial!

[@berna3089]

Pretty cool, thanks for the help!

[@michaeldowning7220]

This was very helpful.

I'm using a Paragon character. When not moving, they're going into the Idle state okay, but when they move, they just slide across with not the proper 'jogging' animation, that would play if you spawn them as a player character

[@XXALEXPROXX12]

Thanks! Nice tutorial bro love it

[@HexevonLugosiart]

Works Great! Thank you!

[@wink3319]

Great Tutorial! Very clear. However, one question: In the tutorial, it is pointed out that we should create a Blurprint for the AI Character and another for the AI controller. We leave the AI Controller blank and Inside the AI Character Blueprint we then assign the AI Controller Blueprint to the AI Character. Then we create the AI Logic in the Event Chart of the AI Character rather than the Event Chart of the AI controller. In the end it works for me. But what if I wanted to create an AI Controller logic that should work for different characters?

[@hurtlockergaminghd3822]

super cool man , think you could do a extended version of this one for fun? making a army of zombies that move as a pack but yet single ? kinda like on Resident Evil 7 - lmao all good though just figured seeing how you did this so easy maybe you would be able to in under 30 minutes haha. xD

[@wilismatrix9847]

Wow short and straight forward

[@m00ntvx4]

for third person anim BP, it doesn't have the little black circle next to it, just 2 figures in a grey block. also it's still doing t pose.

[@rifat.ahammed]

Thank you Soo much

clear fast tutorial no music good voise thanks +sub

[@shamanik1320]

I'm trying to do a behavior tree on a character I spawn in the world from a target point. Does anyone know where I could learn the basics of making that work? Everything seems setup alright but the location on my blackboard just stays the same vector value. Also isn't find point in reachable radius better than navigatable radius? Since it makes sure it's reachable?

[@alexavedis481]

Hello! Works well for me, but when I block in front of the AI character for a while, he well stop movement forever. Maybe I should reset the status when necessary.

[@AceAmStiel]

could you make a tutorial how to add a weapon with shoot and so on to your thirdperson character? :)

[@SaynYT]

Is there a way to make a minimum distance? Like i don't want the ay to move half a meter on even less

[@clebo99]

It sure if you still are monitoring this old video, but I wanted to know how you could do an AI Roam with something that walks and flies? I have downloaded several assets like a dragon and owl thst I’d like to have flying around the map.

[@stellarcommander3456]

Could you show how to make an AI that flies in three-dimensional space?

[@DJL3G3ND]

thanks! I modified it so now a shooting enemy runs around the map like crazy lol

[@chandlerraines9972]

This worked for me I used a mesh I made. is there a way to make the movement more smooth when turning? having a 180 turn is awkward for a space ship

[@MrRalexu]

You can use "Rinterp to" function before "Al Move to" function.

[@brianmarkowitz]

Great tutorial, but im having one issue. When the AI will get stuck on a piece of geo in my scene and it will stop everything. Is this something I can program around or is this an error?

[@DeltaTwoZero]

Copy and paste the logic from On Success to On Fail.

[@fubsy7806]

Great tutorials but i have a problem :( any idea why in UE5 my character slides around instead of moving even though I have selected a mesh and for example I have Use Animation mode : Animation Blueprint, Anim Class ABP_Manny_C then Skeletal Mesh SK_Mannequin or SKM_Manny they just slide around :( any help would be appreciated

[@Capitanazo01]

Cool tutorial :) Where can I find those stairs?

[@tss1473]

in the starter content

[@kongcreations6496]

For the anim class, what if we had our own custom walks and movements? what will we pick?

[@nahiansharif4200]

just select your specific character's animation blueprint for that specific character, it depends on the character model.

[@slowblenders]

How do I add Navmeshtovolume on a game infinite runner? It wont add to the base floor

[@MistahX99]

How would it be possible that my character would move in one room but not in an adjacent room of the same level?? I'm confused

[@thomasemminger1873]

I don`t know if you are still reading these comments but I have got a problem . The AI`s Animations won`t play. How can I fix that?

[@ThePinkOne]

How can I make it go faster?

[@NintendanGX]

Thanks for the helpful tutorial. Could this also work for a vehicle AI?

[@Fullmetal85]

Obviously. But the vehicle needs its own meshes and animations.

[@moazmohammed9889]

hello there , i wanna ask u , why when the AI thing doesnt work when i apply it for another character with another animation ?

[@titanicgames4785]

Hi there. Have you given it an AI controller and placed it on your nav mesh?

[@moazmohammed9889]

yup i did ... actually i just changed the ue4 character to my own character with its own animations.. in the same blueprints but yet it doesnt work i dont why sorry for being late i had exams

[@occy220]

I have problems on getting to move to random locations in the end

[@nahiansharif4200]

thats not random, that's specific points. kzbin.info/www/bejne/Zpi4ZoaqfLikldE check this video, it might be helpful

[@Chickentwn]

Thanks for this tutorial, can u show how can i play HIT animation on enemies? thanks ^^

Sure thing!

InitPathFinding start point not on the navmesh

[@ggmohammed6907]

Why does it not work when I branch it with false

[@lexcelsior]

Thanks for the tutorial! Worked perfectly for me, except that my AI character doesn't recognize that it's supposed to transition to a walk when it's moving, lol. Any idea why that would happen?

[@tss1473]

If you are talking about animation go to viewport select the skeletal mesh and type in animation in the details then select third person animation

[@Ali107]

Works perfectly! but animation not working?!

[@WaywardWayta]

same

[@Fullmetal85]

LMAO You can't do something as simple as this. Think a little and do some troubleshooting. Stop relying on someone else to solve your problems.

[@tss1473]

[@user-lu6zz1hc8p]

Is it normal if my game is 9Gt :_D

[@alexandersmith5464]

im trying to do this in a fps but just wont follow

[@coryhooper8895]

one thing you can do is make a third person project, follow these steps, and once it works you can then use the migrate function! just select what you are moving, and then select the project content folder you want to add it to!

[@jelusmuch4740]

I've done everything the video said to do but my AI aren't moving...Is there any way to fix this kind of complication?

[@DonMatek]

When you place your AI in the world make sure you set it's state to Roam

[@jelusmuch4740]

Matek thank you

[@DonMatek]

@@jelusmuch4740 You are very welcome. Im having a great time learning AI basics in Blueprints before I move to Behavior Tree. So far I have my AI's roam/patrol(haven't added that one yet), have him find the right target (me) or other AI's. When he's too far, will attempt to move in closer and then starts shooting at me. Added a health bar above their heads as well as death animation. :) Oh yeah and they have the weapon from the starter content, took a while to get it right but it works quite okay now. Hit me with any more problems you might have. Good day.

I try "IA move to" after the delay

[@DJL3G3ND]

ok

[@tss1473]

its AI move to

[@faithluxstudio431]

It says "NAVMESH Needs to be rebuild" i have made this but nothing happenes

[@Barnzy_]

hmmmm youmight need to adjust the navmesh box you made because it should just build???
