I like how you demonstrated that binding is inefficient. All it took was printing every time that binding was called and it was immediately obvious why it's bad to do it that way. I think it would be cool if you did more videos like this. I'm new to Unreal so I've been following a lot of tutorials and I have no idea if I'm learning bad habits. I like how you took a method that many other tutorials recommend and explained why it's bad and how to do it more efficiently!

[@LeafBranchGames]

Thank you. I do try to explain good habits and point out bad habits as much as I can remember to do so in most of my videos, although maybe not as explicit as in this one. Anyway, glad to hear you like it, and keep on learning those good habits. :)

[@offirbaruch7895]

I second that!

[@jakedubs]

@@LeafBranchGames Interesting. Kekdot's channel just cast to the player on Event Construct, then set the Character as a variable inside the Health Widget. You can then use that variable in the binding function without casting every frame because you have a reference.. But It's not working well in multiplayer atm. So now I'm here. Any thoughts?

[@LeafBranchGames]

@@jakedubs You can cast at begin play to avoid a cast being done every frame. But that is just part of the issue.If you have a binding at all, all that code will run on tick even when no change is done, which is just wasted performance. It is more convenient, but it is not good. You could just watch my tutorial on health bars for multiplayer: kzbin.info/www/bejne/hXjFnHR8apVnfdk

Thanks for demonstrating how binding is not the way to go when it comes to doing things like this. I had no idea binds run on every tick! I am currently experimenting with different way of accomplishing the same thing within the engine, but have no way of knowing which is the better or more efficient method. Do you know much about how to identify performance issues in the engine and how to fix them?

[@LeafBranchGames]

For these kinds of things you won't likely spot it until you have a lot of UI elements that all collectively take up a significant amount of performance. In general, there are some visualization tools that can let you see if your environment is heavy in different ways. There are also profiler tools that let you see where bottlenecks are appearing for your per frame calculations.

[@AMobOGobos]

I have implemented this with my character, but I can't find a way to make it work for an enemy (since they do not inherit from the player controller). Do you have a video on how to add updating health bars to enemy actors, or some advice on how to do it?

[@LeafBranchGames]

Yes, AI don't have any player behind a screen so there is no point to have a UI for them. So instead what is usually done is either a player has an enemy widget as part of their UI so that you can see life remaining, or you have a widget in the world near the enemy to represent the life. So depending on how the enemy health is implemented to be shown, requires different solutions.

[@retrowrath9374]

Of course. Everything is possible in programming.

Thank you. Sure, you can do it several ways. You can animate a material if that is how you display the progress bar. Or you could use a timer which starts ticking when you change the value. You need to keep track of your current value and your target value. Then when the timer each time get called you move it slightly towards your target value.

Hello, I really liked the way you showed this in detail. I have a question. I have created a BP called UIHUD and put it in the scene so there is no characters to cast. So when I try to cast like you did at the end, can't find a suitable object as I cannot call get player controller or anything. (coz there is none in that blueprint) and I won't have a character in the game, (its an incremental game) so how can I overcome this problem? Got any idea?

Yes, you can call get player controller. I got the player pawn, because that is where I stored the relevant variables for the widget. If you don't have a pawn, then you have those in the controller or an object the controller knows of.

Thank you for this video; I’ve been looking around for this specific demo (on how NOT to use bindings for health). However, I make it to the end and try to update the starting health on EventBeginPlay using the function you created …but it just doesn’t update. I start the game and it only matches whatever I have the percent slider set to in the progress bar widget . What am I missing??

[@LeafBranchGames]

I can't be sure. This would most easily be found out by debugging the problem. If you do not know how debugging is done, I have a introduction to the basics of debugging here: kzbin.info/www/bejne/sH-aiYKJod10gKM

[@TerribleMighty1]

@@LeafBranchGames thank you for the reply!! I think I figured out why it is happening (but don’t know how to fix it). When I was running the viewport , I noticed the debug objects for the character and widget blueprints both have TWO debug objects each. Nodes fire on one object but not the other. For example there’s “Widget_0” & “Widget_1” in the debug objects. Only “_1” is firing the nodes correctly. But on the character side , only “_0” is firing “damage”. Hope this isn’t too confusing 🙄

[@ihatekasper]

in the W_HealthBar Event Graph, if you were doing a health bar for an enemy rather than the player, what would you do instead of "Get Owning Player Pawn"?

[@LeafBranchGames]

An AI can't have a UI, so it would never be getting owning player pawn. Since there is no person watching the screen for the AI, showing a UI would be pointless. So what you are instead trying to do is show a widget for non-AI players, that want a visual representation of some property of the AI in question.

Tried following these steps and watched other videos that are similar. For some reason I cannot get the UI to show on my viewport. I've tried the exact steps did something change? I watch another video and the person added the UI interface but called it to the view port by using a different controller then changing the viewport settings to that new controller but that way seems a bit odd to me. Any ideas what I am doing wrong.?

[@LeafBranchGames]

It depends a little on your circumstances. When you create a widget you can assign which controller it should belong to as input. Make sure to send the player controller that should show it as that input and you should be good.

[@karlschneider8451]

Great Video brother. I was having issues after binding my widget. I deleted my binding and formula after watching that portion of your video. I am still having an issue though where the health bar stays the same when I am playing the game. I threw a print string at the end of my health bar widget logic and it doesnt fire when taking damage. I did a print screen for when I am taking damage and it shows my health dropping so its a communication issue with the widget. Got any advice on troubleshooting or things to double check?

[@LeafBranchGames]

So if the communication does not reach the event that is supposed to fire when you take damage, then that means the binding was not set up properly. So I would debug when the code for binding of the event is to be run,. and make sure that both the object it is binding the event to is a valid object reference but also that it is the object that you are intending to bind to.

The only reason why I would use binding in UI is formatting. i.e: at @17:30 I get it, not casting or excessive calculations. but you can store local variables in UI and just do percentage "formatting" in binding function. OR create "binding to local variable" without function! I see in UE53 I can do that. I wonder if that's more efficient? Then either create custom Event in UI that will run formatting and update health bar OR do through event dispatcher as you did. If hit is taken then notify UI and update its local values. Damage or health up values are int/float, easy to debug & setup. but presentation logic could be done in UI. For now its health bar... but at some point you might want to change it to display health points or both. This way its easy to handle all data presentation in UI.

[@LeafBranchGames]

You of course have to adapt your communication and interfaces to the needs of your project. But a UI binding should never really be used.

Of the bind is called every tick, whats the usecase where it is actually useful?

[@LeafBranchGames]

If you have some UI element that uses logic that is likely going to be updated every frame, then you may as well make use of it. But even in those cases other considerations apply. Since it is going to be run every tick, you should make sure that the logic that is run is as performant and small as you can make it.

[@danielgondos3689]

​@@LeafBranchGames its so weird that an off-the-shelf unreal feature is such a poor decision to use. I would love it, if the easy way would be the right way. e.g.: the bind would look the same, but it wouldnt run on tick. only when the used variables changed. if it uses dispatchers under the hood, i wouldnt care, but would be nice to hook up information performantly, without littering everything with dispatchers and belonging nodes.

[@LeafBranchGames]

@@danielgondos3689 Many features that are available can be bad if used wrong. Just like how you can see plenty of tutorials to hook all logic into the tick event. Sure that works, but just like with binds, it is probably not the best solution and it will cause performance issues as you keep adding classes that has the same approach. "Easy" is usually an indicator that you may have cut some corner that might cost you later down the line. :)

Put what on the controller, the widget? Or the health? If you mean the health, then health is something that belongs to a character, not a player.

Sure it will. You may want to create the HUD and the setup on a different event, like on possessed when the controller take control over a pawn instead because a multiplayer game doesn't load in the same way as an in editor demonstration.

how can i create a potion pickup with this health bar ?

[@LeafBranchGames]

A potion pickup is completely separated from the health UI. All the potion will do is change the health, which the UI will handle itself when the event dispatcher is called. So you only have to code your logic for the potion affecting the health and you are done.

@@LeafBranchGames if ever you want can you give us a little exemple , i tried taking variables from your setup on an actor potion pickup with a box collider, but im having a hard time actually getting the potion to give back health ! , i made the pain collider and everything works fine, but the potion , dont seem to give back health

[@LeafBranchGames]

@@faze0ne844 You can have either have your potion call the damage event with negative value or you can make a new function for healing which works similar to the setup of the damage event with event dispatcher.

Thanks for posting. Quick comment. When you say "lets do it the right way" then start the tutorial with saying 'you shouldn't do it this way, but I am for the sake of simplicity' 3:10 its odd ;)

[@LeafBranchGames]

Agreed. But creating a whole health system for the sake of a tiny health bar felt overkill. :)

How do you do this with text?

[@LeafBranchGames]

Exactly the same way. But instead of a progress bar you have your text driven by the percentage.

[@Xspurr]

@@LeafBranchGames The thing is that a text block doesn't get a variable, like the progress bar does, so I can't add functionality to it in the graph. I was however able to communicate, via dispatchers, to a variable (integer) and make the text show thoose numbers. I choose the variable under Content for the textblock, but I'm not sure if it is just another binding and just ticks away in the background. I hope that made sense!

[@LeafBranchGames]

@@Xspurr To set the text of a text widget you need to call the set text node on the widget component. Then that input would be what is displayed as text. So if you wanted to just show the percentile number you could use that as input after a conversion from percent to text.

[@cvoiceofficial]

Hmmm, how would I do this if my character manually spawns in after the level loads. The health bar doesn't update to full health.

[@LeafBranchGames]

The video shows how to update the health bar as the character spawns. You need to call the dispatcher when you want to update.

[@cvoiceofficial]

@@LeafBranchGames Well that's lame; apparently the issue is I needed a delay. Wish there was a way to do it without it. I am doing the function of on Possess, because the pawn doesn't get possessed right away

[@LeafBranchGames]

@@cvoiceofficial Shouldn't be a problem if you place it in the possess event on the character. Delays should almost never be necessary.

[@cvoiceofficial]

@@LeafBranchGames Don't know why, but for me the delay after the possess event is necessary. It's only at the default delay of .2 sec though

[@LeafBranchGames]

@@cvoiceofficial My advice would be, if you are interested in getting rid of the delay and also trying to get a better understanding, to debug why it doesn't work without the delay.

[@martinberge9237]

Does it work for multiplayer?😊

[@LeafBranchGames]

UI and widgets only exist on local clients.

[@MrDrazeTV]

i cant set progressbar, i can only get it. why is this? this is driving me nuts.

[@LeafBranchGames]

In which context can you not get it?

[@MrDrazeTV]

@@LeafBranchGames When you drag out the progressbar_39 in the graph and chose get or set. I can only select "get". (24:06) On the left side where you can see the variables is says "public progressbar_39", but when i hover the mouse over it, it says that i cannot edit this variable cause its not public. I deleted everything (W_HUD and W_Healthbar blueprints) did everything again, followed your guide and still have the same issue. Im kinda sure its not public even it says it is, cause the "eye" icon on the variable is closed, and on yours its open.

[@LeafBranchGames]

​@@MrDrazeTV The eye icon is usually connected to if something is instance editable, which doesn't really apply for widgets. Clicking on the eye or the instance editable field would affect this icon. But since this is a widget that should not apply. I can not see how this would come to be, what version of UE are you using? Does this happen for all types of widget components you add or just progress bars?

[@MrDrazeTV]

@@LeafBranchGames Im using version 5.1.1, but i cant even open my project atm, it just crashes. I have no idea what is going on. Ill make a new project and see if that helps. Thanks for the support tho, really appreciate it.

[@MrDrazeTV]

​@@LeafBranchGames I created a new project. Still cant assign a value to the progressbar. Im giving up for the moment. Thanks for the help :)

[@pwnonator]

I am confused because this video seems different when i watched it a few months ago.

[@LeafBranchGames]

Maybe it was a different tutorial. I have quite some UI tutorials.

[@aethylwulfeiii6502]

This tutorial is also terrible, everytime I respawn the player after they die, they end up with a health bar that is completely empty? Has anyone figured out how to fix this? Why is this simple stuff always so complicated and convoluted? After I set a branch boolean that if is dead is true then remove from parent target is widget? But it doesn't work!!! Your tutorial is just as bad when it doesn't explain this! There is no point to building a health system if it is not taken into context of death and respawning of the player.

[@LeafBranchGames]

Your negative attitude is quite bizarre. The reason things don't work for you is your lack of knowledge, not the high quality tutorial. If you want something that brings along a context, then look for a tutorial like that instead of a single one that teaches you a specific thing. Here, this will teach you to make everything related; kzbin.info/aero/PLNBX4kIrA68lz8GSxTQKX_0B23tHP6Bl9

[@darkwraithcovenantindustries]

This tut is great, wdym. It never claimed to teach about what to do with a kill condition, but this is very easy to extend using this as the basis. You can set up an on killed event that happens when health < 0, to destroy the actor (self) in the BP of your player character. No need to be negative.
