after this change is the arrow afected by gravity and falls over time, or goes like a magic arrow to infinity?

Great tutorial, but I have a problem, I have items that I manually dragged into my scene and even tho their current position is being saved, they are not replacing the original objects, so the original objects spawn every time I load the game, resulting in several copies of the object, any ideas?

Very cool, but I was expecting to learn how to spawn regular objects, not projectiles.

Hey Ali! Well done as always on showcasing advanced methodologies in Unreal Engine! ^^ I do have a set of questions on this method to better understand how I can use them in my scenario's as well. Since I was following your tutorials I have a Projectile and AOE System with their Child classes set up and in Place. My Project has shooter elements and so I was initially making it that every gun has a Child class of the bullet set up with their own speeds, meshes etc... Some of them also link up with Spawning an AOE Blast type on impact (such as a grenade launcher round) My question is; Since the actor component takes the parent class, In order to keep with every gun to have their own "child", would the requirement be to spawn every variation referenced to be within the pool? Or is there a way this Parent to be transformed into one of its child classes and returned to their parent upon end of use?

I'm curious if there's a more optimized way to create a reference to the enemy base blueprint upon play rather than constantly casting to it in the tasks? It works, but seems like it may cause performance dips later on, especially with more types and classes.

Ali just cant express how important your tutorials are , you make the advanced stuff so accessible and high production , which Unreal Engine community really lacks.

Hey, thank you for your AI series! I don't really know why but I have issue with IsWithinIdealRange, I did every step from your video but I don't have Ideal Range option in details panel. What can be the problem?

I have a problem and I hope anyone can help, 1- There is a collision between me and the projectile even tho I did the “ignore when moving” thing .

Fantastic as always Ali, one of the most unique ways of teaching. Keep it going!!

GitHub available for this demo project ?

A gift I never knew I wanted so badly thank you a hero my game wen I spawn my reward weapon my game freaz for like 1.5 seconds and continue thank you

Amazing video. This is a life saver as I noticed my fps goes down when i shoot a lot of bullets in the game im currently making. Also free palestine!

Amazing!! As per usual, loving this series so far, thank you!

Wow, you actually did it... Literally the only bullet hell tut for unreal. I'm so grateful that you saw my post all those months back and made this.

You mentioned that creating and destroying objects while the game is running affects performance. Is that why games sometimes stutter and drop frames when something happens or objects spawn ? Does this design pattern solve that problem ? at least partially ? I never thought of it, but creating all the entities you'll need for the game while it's loading or being initiated, then just displaying and hiding them later makes so much more sense. Thanks for your videos man, as always they're a treasure trove. And thanks for the support for Palestine and it's people, you're a decent and a good man.

I have a question , when we are standing close to another object close to the back of our character - arrow trace gets blocked by the object behind us (since we are trancing from camera) and arrow fly to the wrong direction - do i simply adjust trace start location to fix that or?

Amazing

Free Palestine!!! Also great video! Thank you!

Hi Ali, thanks for all the great, free content. I appreciate it (I was taught some design patterns but they don't stick if not applied, so this is great). Most applies to my game, though I think you should probably have mentioned the Lyra event bus during that tutorial? Anyway, I'm wondering about 'licensing'. Am I allowed to use your concepts in my game without any regards? And seriously, it's great to see someone interact with the comments section. Feels much more like communication. Keep up the good work! P.S.: As a TH-camr, be careful with white flash bangs (like your ChatGPT at the end). Some gamers/programmers can't handle that stuff at all, very much including myself.

I have a problem where i cant find take damage in the function override panel i have no idea how to fix this.

Excellent video! This is a bit offtopic, but do you have a video showing how to make those spells effects or where to purchase them if they are from the marketplace? The dark smoke effect if exactly what I've been searching for. Thank you.

This is not a tutorial, but a showcase

Do you care to make one for C++? This video was awesome but i think C++ would fit this purpose perfectly considering the boost in performance, i just cant get it done myself so far..

i cannot see the interface in the "create widget" node, i compiled and saved the widget and set "public" the varìable Damagable Actor, so i can't make the health bar work. pls someone know why? PS this tutorials are great keep going!!

EDIT: I figured out what was wrong. I needed to check the box for Success on the Finish Execute in the BTT. Okay, I've read through almost all of the comments, and no one seems to have the same problem I do. I have followed all of the steps, and everything is great so far. However, when we get to the point where we add the BTTask for attacking and add the Wait as the third event in the Sequence, the Wait never gets triggered for me. I watched the BT while running and it goes Move To Target, BTTask Attack, Root, Sequence, Move To Target, BTTask Attack, etc., it never actually goes to the Wait in the third sequence; but, if I put the Wait at the beginning, then it does get hit. If it helps I am using UE 5.4.2.

Ali, you're so good that watching your videoes almost feels meditative. :)

I have a problem where all of the enemies move identically (well not EXACTLY but still in the same path and behavior) which is what this tutorial was aiming for but what if i want them to be different (because usually enemies in a game even if in the same type don't do EXACTLY the same thing, like chase the player from different directions, etc).. like im not talking about patrolling route im talking about when in attack state they chase me until they are near each other and than chase me all from the same direction and there is no variety.

Great series. Would love to see a series on the right way to mount animals/drive vehicles including combat in either situation.

When enemies from different teams merely circle each other without ever attacking, what might be the mistake I made?

Excellent stuff! So much better than 99% of tutorials since you actually teach good design patterns :)

Thank you very much create this amazing optimization tutorial, it was always in back of my head that this method of spawning actors might not good for optimization. one way i was thinking of this method by loading these pools in memory using level blueprint or game mode blueprint so it will load with the game (Just an idea, don't know it will work or not). I will be glad if you make some tutorials for debugging and profiling things, just like checking the memory allocation of these pools and other stuff.

I don’t know if your still ready comments in videos from 4 months ago but if you are I would love love love to see a good weapon system video. I been following someone and watching how they do it but they are in consistent Chang things to much and are just breaking the code. To the point where a game I’ve been working on is now just useless and I don’t know what to do. The video concept was having it where the player can hold more than one gun in inventory. One is in hand. And on is in inventory. And you have an option to put both away and just go with hands. Then he changed them all messed it up and then added an ammo system and it just got all confusing. I do want an ammo system but learning the weapon system and ammo system from someone who teaches like you do would be amazing.

Best Series in my opinion. Keep up the good work. ❤

A much needed tutorial, I really hope you will show other use cases like enemy pool.

Oh wow 20th Comment

My brother was doing that

I have deployed four melee enemies, but only one of them considers the player as an enemy. The other three recognize the enemy that targets the player as their enemy. Where might I have gone wrong? I'm not sure where to start debugging.

Based as always. #freepalestine ❤

Oh wow, great tutorial man, instantly following through all the way along no problem, loved it

can you close a pool at runtime? using your example. u changed build, and no longer spawn fireballs. u do melee dmg now( so drop the pool?) or a frost bolt now. load pool on event (change to frost?) ..... (i guess u could divide it up into particle system attributes and re-use attribs from shared particle systems or projectiles or common actors/emitters etc) but can you close a pool to regain mem during runtime?

One love. Gaza will be free in sha'a Allah

Hello ! First of all, I'm verry sorry for my broken English. I'm from Japan. I discovered your channel recently and I think it's great to watch your videos that offer such quality content about UE! Well done and thank you so much for it! I am contacting you because I have started the development of an Horror Escape Game on PC. I'm really not a professional in this area, at all, and I would love to see a tutorial about more complex features and, very importantly, a real save menu. There are many good tutorials in English on the subject, but, I only see videos concerning relatively basic save system which do not take into great consideration the triggers (using do once or destroy actor), the collectible objects which would be picked up in several levels, the passage between several levels, etc. What I would really like to see is a tutorial that deals with and clearly explains, in addition to what we basically see everywhere, more complex save system: - Saves (in different slots) and loading games menu - Check points (with a list of all saved check points in the save menu, with the possibility of reloading them) - Attribute and customize the name off the saves - Interactive elements (saving picked up objects, multiple doors when the state changes from open to closed, etc.) - Spawned and destroyed enemies (so that the trigger or event no longer retriggers after saving / auto-saving) - Inventory - When and how properly use Game Instance and Game Mode (with the differences between sublevels and levels) - The save logic between several levels (not just in a single level) - The save logic in a game with only sublevels - etc... A video like this, with great teaching like yours, would be more than exceptional and unique ! Thanks again for all your videos!

Honestly a banner at the beginning of the video with good intentions- how can anyone hate it? These videos are great and honestly you are a great teacher. I enjoy watching and learning and look forward to many more useful tutorials.

Great video! Keep doing what you're doing #FreePalestine

been waiting for proper object pooling tut ;), thank you ALi

Hi! I loved all of your AI series and have spent some time attempting to design a game based around it! I wanted to ask, is there any chance you would go back to the ai and include AI soldiers levelling up/gaining experience to become stronger? Have a wonderful day!

Hell yes, Free Palestine. Easy sub, thanks for all your hard work!

i guess if use for forest trees, it would use insane amount of memory, so no use for forest :/

awesome bro great tutorials learning a lot
