There's a bunch of tutorials about this who all do this badly, yours is the only one I found that shines the light on this. Cheers mate!

[@LeafBranchGames]

Thank you, appreciate it!

[@dragallabzpresents]

Being new to Unreal, your tutorials are great. I saw the video like this from a year ago when I was working on the player health bar, and after I looked at a few others I found this when working enemies. I had to make some changes since I use a lot of C++, but without this video I would still be stuck. I also appreciate the demonstration on why things aren't a good practice... like binding. Keep up the food work.

[@LeafBranchGames]

Thank you, appreciate it!

[@EdvardSvensson]

Awesome! Quick question what's that sound in the background? it's like there's a low sound of someone speaking

[@Drakuba]

are those sounds in a room with us right now?

[@EdvardSvensson]

​@@Drakuba I hope not or my house would be haunted. At 2:49 I guess you can hear it more clearly, but it's audible throughout the video

[@LeafBranchGames]

I am unsure. It could have been picking up audio from a nearby device.

[@Rusty0621]

@@Drakuba No, they are in the video.

[@shannenmr]

The double audio / audio in the background does make this video hard to listen to for sure

Your are amazing bro thank you for this tips♥♥

Thank you. :)

perfect ! thank you !

You are very welcome!

This only works for NPCs if the NPC is a child of the player. If you don't have it that way (which you shouldn't unless you have a specific reason) you'll have to create a separate IsOwner for the NPCs, event dispatcher, health, etc. How you "SHOULD" do this is to create a blank character as the "BaseCharacter" that is the basis for which all other characters are derived, reparent your player and NPCs to the base, add the dispatcher to the base instead of the player, and set the interface input to the base instead of player. That way, any alterations you make to the PC have no chance of screwing up something on your NPCs.

go to pixil art, make a circle, fill with some red colors, blur, download. Do the same with a grey one. Use as health globe. Do same for stamina or mana if wanted. Tysm for tutorial

[@LeafBranchGames]

My pleasure!

[@robinsonanimation]

Hey this tutorial works great except if I change computers one computer, the healthbar goes away gradually, in the other the health bar delays and it goes away all at once, is there a way to have this update the same on both machines ? (sort of like deltatime in unity)

[@LeafBranchGames]

Delta time is a time elapsed between ticks in Unreal. I did not make use of tick in the tutorial so it is not really applicable. This works for me on multiple computers. So it is probably something unrelated to the tutorial.

[@WrathInteractive]

The UI owner thing simply doesn't work now even if you take the cast to out as it notes, 5.4.

[@LeafBranchGames]

Opened the project in 5.4 Works fine.

[@WrathInteractive]

@@LeafBranchGames Odd, did it like you and the health didn't work and just swapped to the AI instead, so I was taking damage but the health bar was going down on the AI, obviously missed something, thanks for the video.

[@stoneddevstudios]

Getting weird math, I go from 200 health to -175 after causing 25 damage then goes back to 200 and again to -175. UI goes from full to none..Any clue what’s happening?

[@LeafBranchGames]

Any number of logical errors in your math could be causing this issue. You are best off to debug your issue to find the root cause. Here is a tutorial on the basics if you are unfamiliar. kzbin.info/www/bejne/sH-aiYKJod10gKM

[@kellowattentertainment]

Absolutely amazing. It works perfectly, even if the AI Character child class has different health widgets. I checked. I created an AI Character Base Class and made children, Boss Base Class, regular enemies base class, NPC Base and Companions base. They inherit from the Base AI. You are hands down the greatest. I have a question though

[@SwirlFrog]

what question?

[@gokuvinod2850]

In the last part where u edited a duplicated material and I did the same, and it's working as well, but somehow it feels like low resolution UI and I don't know much about materials can u confirm it's from my side or this technique has this issue in general. Thanks

[@LeafBranchGames]

There are many different settings and parameters that can come into play on affected how they UI will look in 3D. So it is not from your side as such. But depending on your use and what you are displaying, you have to set it up for optimal display.

[@nairolfri]

Nice video, sadly there is an extra audio in the background that makes it less audible.

[@LeafBranchGames]

Thanks, and yes I know. Other comments have mentioned it.

[@mahkhardy8588]

Would be great to see this same example setup in multiplayer with best practice.

[@LeafBranchGames]

It may come in time. Stay tuned.

[@vrhypeguy2119]

at 21:44 I do what you do ad it stops updating. I did the additional add to hud near viewport but that is not what is stopping it, any thoughts.

[@LeafBranchGames]

Make sure to follow the tutorial closely and follow all the steps and you should get the same result.

[@vrhypeguy2119]

@@LeafBranchGames I am gonna restart and see if I can get it right this time lol thanks

[@vrhypeguy2119]

@@LeafBranchGames i did the same again again and it stopped working at the same point. I am in 4.27.

[@LeafBranchGames]

@@vrhypeguy2119 Although this is done in UE5, there really isn't any difference for this between those versions. So most likely you are doing the same mistake over and over again. Make sure you are making all the variables of the correct type.

[@aaronwoods-lee7700]

So I followed this tutorial but for some reason the widget components on my AI characters do not want to update properly. I have a working widget that does update health if I add to viewport for the main character, but if I do as you demonstrated here with the "get widget user object" attached to the interface the values do not update like it does for the main character that is directly adding to viewport. Also note, I do not want to add to viewport for the main character and instead just want there to be an extra bar above the head of the character displaying health. The only reason I added to viewport was to test function. I hope I gave enough information to troubleshoot. Thanks in advance for the help.

[@LeafBranchGames]

Like I explain in the video, they are working the same, just being displayed differently. So it doesn't matter how you want to display it, it should work regardless. Make sure you are following the steps exactly in the tutorial, then when you have it working, you can alter the functionality to how you want it to work.

[@MIIFO3]

Yo, I'm new to all of this i barely know some things about landscapes and other stuff Iam thinking about making an rpg game with a special and really good vfx like when the character wave its sword or some other effects depends on the character My problem (obviously have a lot ) currently is with blueprints and vfx i don't even know how to make a loot chest that spawn random loot in blueprints so any freaking tutorial you can suggest me ? (Something like teaching a child how to walk? )

[@LeafBranchGames]

This is a good video to learn a lot of basics in UE5: kzbin.info/www/bejne/pYOzqa13rr14oNU After that, this is the best RPG series on the internet: kzbin.info/aero/PLNBX4kIrA68lz8GSxTQKX_0B23tHP6Bl9 But it is a bit advanced, so if you have trouble following along, you may want to watch videos from the beginner playlist: kzbin.info/aero/PLNBX4kIrA68nyGfIKgyizftebllhKc4ZX
