amazing as always! Just a suggestion tho, maybe speak a bit louder, at certain times you're almost mumbling but it is understandable, thank you again for a great video!
Thank you for the video! That's the first time I work with AI and I'm glad that yours is the first video I found! Everything is crystal clear and well explained, you got a new sub! Are you going to cover this also in C++ or do you have any resource to recommend? If the different in performance is significative I'm definitely going to use it!
Thank you very much for the support and the kind words. :) I may cover it in C+ down the line, but that is probably quite far into the future. I don't know of any good C++ resources for AI unfortunately, but surely there are some out there.
The AI perception component is super finnicky in 5.4 right now. I can't get both Sight and Hearing to work at the same time and if I want to change the perception type, I need to delete the component from the AI Character blueprint and remake it. I had to restart UE a couple times too because even remaking the component wouldn't always change which sense I was looking at.
It is usually a good idea to stay on the latest stable Unreal engine version, in this case 5.3. The newest version usually need to mature and sometimes have issues. Unless you need a specific feature in the version.
Great video as always! Thank you. Just a question: I noticed that (at least for me) if the seen character does not move even if age remains zero after a while the AI will trigger the sense as "false", as if the character was not there. Basically it looks like the perception just perceives the movement and not the character itself. Is it normal? Thank you!
Performance wise it is probably perception, but I can't say how by much. So if you can do everything you need in perception, try to do that. Use EQS when it is the only other solution.
EQS should be used only to find places to navigate to afaik, for detecting things in the environment for other purposes, like identifying an item or a player, you should use perception
Great time watching it, I am a beginner with UE and in a pinch, hope you could help, trying to make an enemy ai that follow player when seen and eventually do damage when in acceptance raidus , and stop following when player is not in field of view. I do tried with Pawn senseing as well as BT, used AI move To function follow the player. But the Ai move to function won't break, let say when I hide behind an object. though tried with BT to first find player location and then move to that location. But it do feel like the enemy I wanted to create.
If your sense gets updated so that the AI no longer sees the player, then you need to make sure to update the blackboard key that you are moving toward. You can't see the player so you should no longer have the player as a set object to move to.
Please Help! I have ue5 and when I hit run and access the debugger like at @11:10 , the window of the BP_AICharacter takes over the view of my 3rdperson character. What's it called and how do I search for it to resize it? Thanks!
Okay I figured it out! If Anyone else has that problem, here it is. In the viewport look for the hamburger button(3 horizontal lines) in the upper left corner. Select it for Viewport Options > Advanced Settings > Look and Feel > Camera Preview Size. You're Welcome
at 10:00 when i hit the apostophe key the ai debugger doesnt open. even if i change the keybind. when i force it open with the consolecommand EnableGDT, i get the ui with 0 for navmesh 4 for perception etc but i cant see what the ai sees. what is this? i dont know what to do anymore. reinstalling ue5 didnt help.
The legs are driven by its animation blueprint (you can find a tutorial on that subject here: th-cam.com/video/40-V4kYDe1U/w-d-xo.html). So it is depending on how your character is setup to move. A default third person character for example has a blendspace for moving that is determined by a variable that is set from velocity. So as long as that one has velocity, it should identify it is a moving.
@@OpenWgamer There is no correlation between the visual representation and underlying systems. You can draw a debug sphere to get this effect anywhere you want.
@@LeafBranchGames I guess i'm asking what the underlying system is? A simple raycast does the trick most of the time but often you'd want your character to be spotted even when halfway behind cover. Right? That's what i've been trying to figure out and wether or not i could modify it for my own project to shoot multiple probes and determine a targets visibility based on the amount of probes that hit f.e.
@@OpenWgamer Unreal engine source code is freely available to read or change. You can open up all the code in visual studio and examine any part you are interested in. Dig in! It will probably be a very interesting learning experience.
Bro im newbie to unreal how i can declare into C++ a UAIPerceptionStimuliSourceComponent and whats the correct way to attach this component to the Default character in the cpp i want every component to inherit from c++ but somehow when i compile i get errors seems im missing sometyhing after doing the createDefaultObject and all the rest.
@@Damian_DH There may be some C++ oriented tutorials on AI out there. Might be better to follow one of those so that you can more easily get a grip of the syntax on the topic.
@@tristanbaker8198 No, it needs to fulfill other criterion as well, like fulfilling the parameters shown in the tutorial as well as be within the sight radius. I think I show the debugger for the AI in this tutorial of how the detection works.
@@LeafBranchGames isn't is not good for performance to keep things in the world, even if they have no collision and hidden ? i'm interested in a way to report the noise and delete the actor after.
@@IsaacCode95 It is a good approach to clean up actors in the world yes.For that purpose you could set the lifetime of the actor after reporting the noise. Which is similar to what you suggested. The problem with such an approach is that you don't know how long your AI will investigate. So the destroying of actor might happen during that going on. Another way would be for the AI to signal to the object once it no longer is interested in the sound, and remove the object then. Or you could simply have the noise event reported, have the AI "register" the sound and the location, but disregard the objects location. Now your AI can see this as a general area of interest and investigate around there. So you can destroy the actor quickly.

Your tutorials have been great for someone starting to learn the engine, thanks again
Thank you, that makes me happy to hear. :)
Yea! My first roaming AI Completed with no dreaded sliding. Looking forward to completing the full AI series. Great tutorials, well explained. Thanks.
Thank you Martin, appreciate it. :)
Man you really saved my entire course... my teacher recorded it but i think he cut somethings like that hearing sensor... anyways.. thank you so much!
My pleasure!

How long before that behavior happens? I have not seen that before. Have you tried debugging the behavior to see it isn't caused by other code?
@@LeafBranchGames Yeah I am stupid :) when it lost the hearing it cleared the target... doh... thank you!
@@stefanobizzi9863 No problem.
I know we can get ai to hear the ball but how can we get him to see the ball
Is there any way in blueprint for the Enemy AI to detect my head instead of center mass?
what is more better finding player using EQS system or AI perception
Performance wise it is probably perception, but I can't say how by much. So if you can do everything you need in perception, try to do that. Use EQS when it is the only other solution.
@@LeafBranchGames Performance is main thing😅i think perception is made for being used for sight I think I I'll use EQS for hiding from player

when i hit the apostophe key the ai debugger doesnt open.
even if i change the keybind.
when i force it open with the consolecommand EnableGDT, i get the ui with 0 for navmesh 4 for perception etc but i cant see what the ai sees.
what is this? i dont know what to do anymore. reinstalling ue5 didnt help.
Make sure it is the apostrophe key on the language setup you are running.
Good stuff! For some reason my AI's legs dont move, just hovers when following me. Any ideas for a resolution? Thank you!

the debugger doesnt change when i try to toggle through it
Doesn't change how, when you toggle what?
in unreal engine 4 you cannot expand the senses from the right menu :( should do new sense totally with own settings somehow
i clicked wrong place, found it also on ue4, my bad!
Glad you figured it out.
So UE4 (and 5?) by default use a sphere cast for visual perception of objects and characters?
You mean because the percieved pawns are showing a sphere at their location?
@@LeafBranchGames Yea idk, just an assumption. That's why i'm asking.

Is it possible to debug Perception in overview (viewport) mode F8?
What do you mean by overview mode?
@@LeafBranchGames not possessed.
@@boombyte8849 Your debugging is dependant on your selection in the outliner.
@@LeafBranchGames I know. But only in Play mode (in possessed character). It's not convenient.
Does the AI know to look for the player character by default?
What do you mean?
@@LeafBranchGames Does the AI automatically perceive the player as long as the AI has a "sight" sense?
@@tristanbaker8198 No, it needs to fulfill other criterion as well, like fulfilling the parameters shown in the tutorial as well as be within the sight radius. I think I show the debugger for the AI in this tutorial of how the detection works.
22:40 what if i put a delay of a number of seconds, after the report noise event
will it help ? will it work for a few seconds and then stop ?
Will it help with what?
@@LeafBranchGames will the ai detect the sound before the actor gets destroyed after a short delay ?
@@IsaacCode95 The noise has already been reported. A delay after will not affect the event of that triggering in any way.
