@PendingKill 3 года назад

A big thank you to viewers who pointed out ways to improve parts of this system! Here are their suggestions: 1. 07:05 To easily center the widget, place the anchor in the middle, then go to the alignment section and for both x and y put .5. Also tick the checkbox “size to content” that will make the box be the size of whatever is inside it. 2. This health system could potentially be improved by refactoring it as an actor component. Will plan on covering this in a future video :)

@MaximilianMitchell 3 года назад

Glad to see my comment on Reddit for aligning the widget to the center is here. Hope it helps people! Great video for beginners!

@sebastianvoinea1189 3 года назад

Very Good tutorial but If you want to make a checkpoint this system wont work because at the end it just restart everything. If you wanna make this system to work with checkpoints I recommend to make a transform variable and then set it to the spawn location. And after that instead of restarting the game just spawn the character at the position that you set in the variable. (My explanations are kind of bad I know)

@IoSkyBoyoI 2 года назад

@whoissyx 2 года назад

this tutorial is awesome but I am wondering how you would go about making health as a standalone parameter to individual characters that is then called into the damage bp to be used so you can have unique health amounts for each character in a game(if this is at all possible)

@dylanroemmele906 2 года назад

You probably already got it but incase someone else doesn't, each instance of the character blueprint health variable is unique.

Hi is there any other way i can restart level without changing level parent because when i reparent my level all ther stuff malfunctioned and i had to go back

i got a Big Problem. if i am Opening another Level ingame, it says "you Died" but you can play the Character. now if you Die, it restarts the level like normally and the Text is gone. so, if i remove the Parent in the Widget BP, it doesnt show anymore in the normal Death-Screen.

@SegoItChUA 2 года назад

@CommanderColson 3 года назад

Is there a way to have health slowly deteriorate over time, only to be replenished when the player picks up a consumable ('food', 'power up', ect)? Think the Health+hunger+hydration system a lot of survival games have, but simplified into one single life bar

@PendingKill 3 года назад

Sure, you can have a timer set up on a specific interval that will decrease the player's health every time it gets called.

@deceptivetorch7557 3 года назад

How would I go about removing pre-existing UI (such as an onscreen reticle) whenever the “You Died” screen appears?

@dragishawk9564 3 года назад

To remove widgets from the screen when your character dies and the Death Screen (as I call such screens) appears, you'll need to get the widget you want to remove and then use Remove From Parent in a way similar to what this tutorial does for the Death Screen after two or so seconds and the game restarts. I had to cobble together something like this for getting rid of the health bar that I was implementing with this system, since it was still onscreen when the Death Screen came up for me.

@Scionate 3 года назад

You should really look at the overview of the engine framework in the docs and test that respawn in standalone.

@foxywoxy0w068 3 года назад

So I followed your video but it doesn't seem to be working at all, I'm doing a Side scroller so I don't know if that affects it in anyway but when my character touches the cube, they don't die at all. Which is weird as I'm pretty sure I did everything right, unless this type of death only works for Third Person and not Side Scroller.

@PendingKill 3 года назад

The death should work for side scroller. Perhaps you can check your collision settings, and step through the blueprint logic with breakpoints to make sure the death event is getting called.

@Primoris 3 года назад

How would you stop the death screen from displaying when you change levels?

@PendingKill 3 года назад

I believe that as it's set up in the sample project, the death screen only displays when the character's health dips below 0, not when the level changes. But if you're trying to change levels after the screen is already showing for some reason, you could call the "Remove from Parent" function on the widget.

@mythanimation4547 2 года назад

When the player dies, it goes straight to "Game Over" instead of fading to black. Is there a reason why that might be the case?

Do not copy paste the nodes. You need 2 nodes. Get Player Character and Get Player Controller. Get Player Controller > Cast to BP_PlayerController > Call On Death. It should work.

hey hey! so just a quick question! I followed your steps and obviously they worked (don't want to get off topic here but for some odd reason when it comes to making some things in ue4 like my games movement mechanics I have no issue but simple things like this are really hard) but what I wanted to ask was when I use your system I can't get a binding for a progress bar to show current player HP to work! it just tells me something like HUD does not inherent from. I'm fairly new to UE4 and game dev overall so if someone could help me fix this that would be greatly appreciated! the current setup I had that was working until I used this was a cast to first person character and then current hp/ max hp

@PendingKill 3 года назад

how do i add a health bar?

@N0T_Dem0n 3 года назад

How would you make a health bar from this health system?

@dragishawk9564 3 года назад

There are tutorials for implementing health bars elsewhere here, and they aren't too complicated to implement, since they key off the same variable (Health) as the damage system that is outlined here. You'll just need to stick in a Remove From Parent function for the widget in question when it comes time for your character to die, otherwise that health bar will stay on your screen when the "You Died" screen shows up, as it did for me before I cobbled together a solution. You'll also need a way to ensure that the Death Screen comes up for you and you alone instead of having it go off when you kill an enemy, but Pending Kill likely has a tutorial for handling just that.
