Unreal Engine 4 Tutorial - AI Pawn Sensing

[@Matthew.1994]

he chases me until he is on my position, how can i make it so he is chasing me until i am out of the view cone and he stops?

[@spinav]

KleytenHD I'd like to know this as well!

[@gustavopch]

I don't know about previous versions, but in UE4.8 the AI character doesn't stop chasing when it gets to my player. The thing is that it's easier to get away from the view cone when your are at the top of the cone.

[@RohitKotiveetil]

You're awesome dude! I've been thinking over how to implement pawn sensing in my game once I start working on AI. Nice to know that there's a default setup already existing in the Engine.

[@SeanBattle]

Tesla Dev is truly the man!

[@Jamiex305]

Hey did u ever do that video on the hearing side of the AI ?

[@SystemUnderSiege]

Love your tutorials, quick and too the point, much appreciated!

[@2010Edgars]

Simple add "Nav Mesh Bounds Volume" and scale for all area you want to let follow you. Its works. Thanks Tesla.

[@Rizz0NLGaming]

Nice tutorial man, short and sweet :)

[@TeslaUE4]

Rizz0NLGaming Thanks! It's what i aim for =]

[@shingAMarie]

Hey Tesla, how do you make it so that if the enemy pawn is not sensing you, that he just walks around randomly. And also if you get out of his sensing range, he stops and just walks randomly. Thanksl

[@shanilwijesinghe5201]

I couldn't find On See Pawn even when I toggled context sensitivity. (Maybe because I now use Unreal 4.15.3). If anyone else is stumped on that, what helped was selecting the variable Pawn Sensing on the left and then right-clicking on the event graph. You'd then click a drop down menu called "Add event for pawn sensing." And then click another drop-down menu called "Event Dispatchers." You should now be able to see "On SeePawn (PawnSensing)"

[@CarlosCoronadoGameDev]

Can the player be occluded by geometry with this method?

[@TeslaUE4]

Carlos Coronado I think so!

[@joebonds3072]

I've been looking everywhere to find a BluePrint way of getting the AI to follow me and JUMP to follow me. Need Help with the JUMP

[@kyle-carpio]

Hey, where is your hearing tutorial?

[@Broockle]

Awesome How do you set the movement speed of the pawn though? 🤔 EDIT: o it's in the Character Movement Component. "Max Walk Speed". Not sure why this is measured in cm/s 😅

[@valkaranentertainment9049]

I have it set up where a character can walk by default. How would I make the character run the further away I get?

[@pvalencia]

Thanks for this awesome tutorial, it's incredibly helpful! You make it look so easy. Keep up the great work

[@TheDunkelschatten]

Is there a possibility to let the ai look for the physical body parts instead of the pawn? I'm making a VR game with a full body, and this would be essential for the gameplay. Thank you!

[@r.a.h.company9469]

my AI can see trough walls/static mesh... can you please tell me how to fix?

[@TheBrokenSolstice]

but "cast to myCharacter" is no longer there... And I can't connect the "Self" reference to the Pawn input..

[@TroJanVirusMusic]

"myCharacter" is a placeholder. Yours may be called something else depending on what you named it. Have you set up your game mode? If so, check which pawn is being spawned when you press play. If "self" is not connecting to "Pawn" I suspect the above information to be the issue, (your gamemode settings).

[@spinav]

Hi Tesla, for some reason it doesn't work for me. My ai is a character blueprint... seems the AI move to doesn't work. Any ideas?

[@8KEN]

How would it work for when the AI is in the players vision? It doesn't work as the Pawn Sensing is for AI?

[@everettlee79]

Have you found a fix for this? I am running into this problem.

[@moviemonster99]

Hi Tesla! Would you have any tutorials on pawn sensing (Hearing). AI looks kinda silly if your behind his back. Would be nice if he herd the footsteps that way he probably turn around. When ever you have time THANKS>..!!

[@moviemonster99]

HELP!. Tesla could you please tell me what option do I have to check or uncheck in order for AI not to collide with static mash objects inside the Navmash. When Ai hits the Static mash it restarts the level. Restart is ok but only when AI collides with my main player. Help really need answer Please. Thanks Tesla!!!

[@kseverens]

Is there a way to trigger/switch a boolean on/off using pawnsensing? I want to use this to trigger my behaviour tree and animations. I have a free roaming (random walk and stop behaviour) zombie which chases the player if he gets within vision range and stops when he gets out of the vision range.

[@ChristianConspiracy888]

ive used this tutorial before for other projects an it worked fine but i am working on a vehicle project and cant seem to get anything to follow/sense the vehicle :( anything different i may need to do for a vehicle compared to 3rd person?

[@BizzVisuals]

Is it possible to use the ai pawn sensing on the player so that when I see an enemy it fires an event?

[@RavageStudio]

How could you do this a way the ai would react to sounds?

[@adamjones6473]

Hi, I'm doing this using sprites and I'd like them to stand up straight without rotating. Would anyone know the best way to go about this? I want the sprite to follow me I just don't want it to face me.

[@ipasthemaster]

Strange there is not a OnNOTSeePawn event implemented. How do I solve this ?

[@mythical_pizza]

+ipasthemaster use a boolean variable. If it's false then just have him do the other stuff he'd do when not seeing.when the onseepawn is active, make it true

[@everettlee79]

How would you set the Boolean to false when you can no longer see the player?

[@azythegreat]

This is when Ai detects and starts chasing you. If you able to run away and is out of range, the ai still chase you. How to stop it?

[@matiasvlevi6647]

can we make a 360 pawn sensing?

[@nekrosprime1553]

How would I disable his pawn sensing

[@connormcfarland5207]

the AI doesnt chase for very long. any ideas?

[@adelmo83]

thank you very much, excellent video, anyone know how to do to slow rotational and movement of AI character ?

[@Funktionreal]

Hey tesla absolutely loving your work. Just wondering if you have any plans for 'companion or pet ai' tutorial would be interested in checking it out Keep up the good work

[@Wattsy]

tesla, how do I make so that he roams when I am not seen

[@Raidbollen]

How can i tell the enemy stop follow? ^^ thanks for the tutorial

[@moviemonster99]

Amazing tutorials! How ever when I add sound to location the sound is looping every half second instead of playing the whole sound which is about 5 sec long. I selected (looping) in sound settings and didn't work neither with wave or sound cue. I just wan the sound to loop from beginning to the end. Also the sound dosen't shut off when running away from the AI enemy character. Seem like play sound at location not working.

[@TroJanVirusMusic]

Play sound at location is just a node to play sound from a specific location as opposed to play 2D sound which will play it "IN" your game which is designed more for the player themselves, like ambient music etc. If the sound is not playing completely I suggest testing the audio in the engine to make sure it is indeed the full loop by opening the sound/sound cue and playing it. If that is all fine I'd say some other theory is preventing the sound from playing and without any context it's hard to diagnose what is wrong :/

[@moviemonster99]

Ok explain these. How can you make Ai go around static mash without restarting the level. Was set up to restart the level when it collides with the main player how ever it has the same restart level effect when it touches static mash objects in the bouding nav mash. I want turn off the option some have in the static mashes. Any idea??

[@TroJanVirusMusic]

I need the logic you use to call that restarts the level. Without it I'm only guessing. Try uploading a screen shot to imgur and linking it here, alternatively flick me an email at [e-mail] But if I were to guess, I'd say you were running the restart command whenever the AI "collides". Problem may be that "Collide" isn't specific. Perhaps changing the AI details so that it can only collide with your pawn/character for testing purposes.

[@moviemonster99]

Thanks. But I tried bunch of different collision options but no luck. Probably didnt do it right. Waiting for Ben's answer see what he thinks. Also I notice that infinity blade characters dont have no collision. So i put block all collision settings but still nothing. Any idea why block all collision would not work?

[@MyPixHD]

Steam matchmaking tutorial ? ^^

[@Lumhax]

Hi tesla ! I've a question, i want to make the fairy in zelda so she follow the caracter but move too, how can i do it ? ty :)

[@TroJanVirusMusic]

Replace the inherited static/skeletal mesh of the AI following with your Zelda model instead. So: In your AI blueprint left click the skeletal/static mesh in the component window then in the details menu replace the "Static/Skeletal Mesh" with your one (Zelda). Giving Zelda animations to walk and run is up to you. There are plenty of AI animation tutorials out there.

[@Lumhax]

+TroJan_Virus Yeah ty it's working ^-^

[@TroJanVirusMusic]

+Shadow - UE4 & Games Glad to hear it!

[@DjMatrix619]

I followed each second of this tutorial, but this doesn't work to me. The character doesn't follow me at all. Any idea why?

[@nicolamiotto6324]

+Marco I. Post a screen of you blueprint, it's hard to tell why this is happening without infos. Maybe the speed of your pawn is set to 0?

[@DjMatrix619]

+Nicola “UnhardcoreGaming” Miotto I built an entire new game before your reply. :)

[@nicolamiotto6324]

Indeed I thought a month could have been a bit too much time, but who know for sure? Hahah

[@yaboyconnor2240]

Hey Tesla, how are ya?? I have a question for you & am kinda struggling to find an answer... How do you make ai make a sound when it spots the player?? Sorry I’m kinda new to UE4. Cheers!!🍺👍🏻👍🏻👍🏻 Edit: Also, can anyone else help?? Any guidance is HIGHLY appreciated👍🏻👍🏻👍🏻

[@N1LSS0N]

Import audio to your project, then add the audio to your AI (also turn off auto activate in the audio details so it dont play in the beggining) then after "AI Move To" add your audio and a node called play (i think). ask if you need more help! :)

[@LrdOfNightmares]

THANK YOU VERY VERY VERY MUCH MATE!

[@TeslaUE4]

LrdOfNightmares No problem haha!

[@andrelouvier]

Hearing vid?

[@EricMcClair]

Deos this work on 2d games too?

[@Pahan75D1]

yeap, but one man do own sensing for 2d siegeandsandfox.com/dev-blog/dev-blog-ai-cone-ception/

[@__dINe__]

Basics of "Hello Neighbor" i guess :p nice tutorial!

[@blakegt.7326]

I waited 4 years for Hearing tutorial..... but soon never came.
