About me:
I've been learning game development for a few years now, I do have a background in software engineering, and I also have a background in education, so being able to combine my love of gaming, software engineering and education is the best way to spend my time.
I am currently working on this 3rd person action adventure game as a hobby, but I am also trying to build a community, thus I am creating KZbin tutorials to find others who are interested in game development and design.
If you are interested in learning more or if you are interested in working together, please let me know in the comments.

Thank you ! Glad you liked it. There are 2 more videos coming soon

[@Leonardo-zb6ho]

Hello Ali, thank you for the amazing tutorials as always. I made the boss just like you, from the enemy base, but even with the Behavior Tree of the Melee enemy he's stuck in the passive state. He equips the weapon and sets the focus on me, but doesn't attack and doesn't walk towards me. The same behavior tree works perfectly with the melee enemy. Thank you for your attention, you're incredible

[@Leonardo-zb6ho]

I just saw that it's actually stuck in "Is weilding Weapon", so after the wait he executes the "Is Weilding Weapon" over and over

[@Leonardo-zb6ho]

Nevermind, I forgot to set "IsHoldingWeapon" to true after attaching the weapon to the boss... Thank you for your attention as always lol

[@AliElZoheiry]

Hey there! Thank you for your kind words. Glad you figured out the issue. Well done 💪

Hey hi, just stumbed across your channel and your tutorials seem very thorough and in-depth. Just wanted to ask are you going to continue this Enemy series or Unreal in general. And if yes, what are the things that are coming up. Just loved your videos and subscribed.

[@AliElZoheiry]

Hey Siddharth, Glad that you like my tutorials, thank you 🙏 Right now, I'm going to take a break from the AI tutorials and focus on other topics, but I will eventually come back to it and add some more functionality, though I haven't decided what or when yet

[@alhosamspirit8044]

Hey Fuad, glad you liked it, thank you for the suggestions, I already finished the boss fight and will upload the next 2 videos once they are ready, hope you enjoy them

[@allthefame37]

DANG, bro! This is awesome! Will you be doing multiple phases in the boss fight?

[@AliElZoheiry]

Thanks man! I didn't implement multiple phases, but I briefly touch upon how to increase difficulty as the fight progresses

[@oliver7garcia31]

Hi Ali, I would like to remind you that you teach very well, I wanted to know since you have done software engineering if you can recommend any book about programming or techniques about it, thanks!

[@AliElZoheiry]

Hi there! I'm glad you find my tutorials helpful. As for books on programming and techniques, I'd recommend "Clean Code" by Robert C. Martin and "Design Patterns: Elements of Reusable Object-Oriented Software" by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides. Both are excellent resources for improving programming techniques. Enjoy your reading!

[@oliver7garcia31]

@@AliElZoheiry Thank you so much Ali for recommending the books!!! As always a great contribution

[@vidwardio3202]

hi there, @alielzoheiry, for some reason all my enemies have stopped moving for some reason. Even the mage enemy is not able to teleport. but the enemies are able to do everything else. Can you pls help in this regard? Thankyou

[@AliElZoheiry]

Hey there! Sorry to hear you're having troubles, though I can't tell what the problem is from this explanation alone. I'd suggest debugging it a bit using print statements and break points. I also have a video on how to find and fix bugs on my channel, so check that out

[@xenocreatives6456]

yasssss!! coolnesss!

[@AliElZoheiry]

Glad you think so 🙏

[@patrykleveldesign]

In general, in this entire guide, I miss connecting it with the abilitysystem to make more sense

[@AliElZoheiry]

Hey Patryk, are you referring to the unreal "Gameplay ability system" or something else?

[@kellowattentertainment]

Ok, I've discovered a new issue. For some reason, the AI controllers for the Boss and the Base enemies can conflict with each other even though one is a child of the other. I'll explain. I have a Boss character that patrols around around the area randomly when in passive. Even though he has the Boss AI controller, when he switches directly from the Passive state to the Attacking state, the Behavior Tree switches to the Attacking state immediately, but the patrolling state continues until character gets to the random patrol point where it was going to before the state switched. It also does everything in the attacking state, even attack, while still moving to the patrol point. It would mean that both states are active at the same time even though it's on a selector. The patrol (passive state) is not aborted immediately. Or is aborted only after the random patrol point is reached. I've change the character blueprint, I've changed the behavior tree, changed the AI controller. which when I switch the AI controller to the Base, it works perfectly. It means that both controllers are being called at the same time onto the the Boss Character... and the behavior tree cannot differentiate between the two.... which is weird. So, I'm gonna set the Boss AI controller to be a duplicate of the Base AI controller, instead of a child. That should fix the issue.

[@AliElZoheiry]

Hey. I appreciate you sharing your findings, I'm not really sure I understand the issue you're describing, because there can't be 2 instances of a class running at the same time on a single object instance, but I assume there is something else happening. I hope it resolves the issue. Keep me updated!

[@zrmdevelopment7260]

Nice!!!!!!

[@AliElZoheiry]

Hope you liked it, the next 2 are even better ;)

[@inertiavee31]

Hey I got a slight problem, for some reason the health only updates on death, I followed the steps to a T but it's still happening, any help would be greatly appreciated ☺

[@inertiavee31]

HAHHAHAHA NEVERMIND I had the health/max health division in the wrong order

[@AliElZoheiry]

It's always these small things that end up getting us :) Glad you figured it out!

[@Supriya_tripathi257]

At the last time when he avoid attack of player then after he didn't attack ?why

[@AliElZoheiry]

I noticed this happens sometimes because of a bug in unreal engine. Sometimes when I restart the project, some of the behavior tree task values get reset to their default, and that was the case for the one of the tasks, so I just had to set the attack target key to the right value again

I created the base enemy in the first episode and kept adding to it throughout the entire series

Is that the end of this series?

There are 2 more videos to complete the boss fight, then I will stop working on the series for a bit, but I will probably come back to it later
