This is very well done. Thanks for putting this out. I was pondering over how to make the AI hide at the right spot and you cleared it for me. Much appreciated!
Pranjal, you are a gem. Not many people would go out of their way to share their knowledge, which already makes you special. But not only that, you share knowledge in c++ which is very rare to find. And to top even that up, the knowledge you share is very advanced and you make sure to explain what you do aswell as why you do it. I've never seen a tutorial this advanced about AI in general and let alone in c++ and you motivate me alot to try and get better at game dev. Thank you for being this awesome, I obviously subscribed, liked and turned on the bell and I will try to do my small part and spread the word of your channel. I wish you and your loved ones all the best :D
This series has been a great journey into understanding AI, behaviour trees and C++. Exactly the thing I needed to kickstart myself into this direction and understand how to approach some of these challenges. Infinite thanks my friend!
Yes I will be making more tutorials but at the moment I am busy with client projects......I will get back to doing tutorials when I have some free time
Using this as a base, I have implemented a struct to create groups within in the faction, so the defenders of a faction are not limited to engage only at one location on the map. This uses simple proximity based clustering (clusters can also be dissolved or some agents absorbed by other clusters). I found that this approach makes the AI look much more proactive, especially since agents that enter a cluster get the target of this cluster, even if it is not detected by their perception. Also, I have added an additional actor that is just a collider, that allows me to designate any part of a level as cover. This makes level design much easier in my case since I do not have to create many different cover blueprints.
@@pranjalbhattacharjee5601 thanks mate, as my speaking in English not so well, i only uploaded videos without voice so far 🤣 thanks! And forgot to mention, great efforts you're making for these amazing tutorials! Keep up the good works! This AI system looks amazing for my project 😍
I think the formula for AngleToTarget could be simplified a bit: const FVector coverSpotForwardDir = CoverSpotMarker->GetComponentRotation().Vector(); const FVector coverLookAtTargetDir = (Target->GetActorLocation() - CoverSpotMarker->GetComponentLocation()).GetSafeNormal(); AngleToTarget = FMath::RadiansToDegrees(FMath::Acos(FVector::DotProduct(coverSpotForwardDir, coverLookAtTargetDir))); This way you do not need the KismethMathLibrary and it is probably a bit more performant than to calculate the look at rotation only for retrieving the vector (of course it probably does not really matter that much). Anyway, I really love your tutorials and hope there are more to come
I may be wrong, but I find both formulae to be more or less the same but, if possible, do some performance testing and let me know.......and more tutorials are coming but it will take some time because I am currently very busy with client projects,

Hey really nice work ! Is there a way to do exactly the same with blueprints ?
Most of the things in the project can be done in blueprints but there are some perception related stuff that are not exposed to blueprints so you will have to use some c++
Simple Question : How u Make the AI Take Cover in Opposite Direction .. Altough it had collider on all four sides how the AI knows ..
I do some vector math to figure out the correct direction.....just watch the tutorial man I explain everything in detail
If I download the project files I can use it in my project or not because I am not good in c++
Yes you can use the code and assets in your project but if you sell this project as is, give me proper credit (mention my name and provide links to my youtube channel)
Is there a way to make this system more dynamic? For example to generate the cover instead of manually placing volumes in the level

Hey,i use 4.72.2 and i get the "try rebuilding from source manually" error when i try to recompile the project.How can i solve this.
