blueprint

[glossy cloak]

Then not really. You'll need to have the player press a key on the character or player controller bp which would then send a message or call an event on your actor.

[steady night]

hmm having a hard time narrowing down that this frame is

[gaunt monolith]

ah oke, thanks anyways

[narrow sentinel]

Anyone know whats happening there ?

even though I've set max to 2000 mb it seems it's not using it or something

[thin panther]

Change that v3 to V4, and it should work

[balmy jackal]

Thanks again, found that solution in reference to that message, it gets rid of the related text in the log but doesn't solve the issue. Currently digging through anything related on forums

[dark drum]

Add event dispatcher to widget called 'OnWidgetRemoved'.
On the widget override the onKey down event and check if the down key is the key you want. If it is, call the event dispatcher and remove from parent.

When you create the widget (Before you att to viewport) bind to the event dispatcher and when it's triggered have it call a function or event.

[maiden wadi]

I'm not saying you NEEEEED CommonUI. But...

[dark drum]

*OnDeactivated...

[maiden wadi]

Honestly don't know if I could maintain my sanity making a game without CommonUI at this point.

[blissful grail]

I do all the time 👌

[dark drum]

CommonUI does offer a lot of useful features. I can't wait for more of it to be documented to be honest. Not checked in a while though so I'm probally getting ready for another rundown lol.

[maiden wadi]

It hasn't really changed much It's all basically the same. They're trying to add some data driven stuff, but I recommend avoiding it for now. The enhanced input support and especially the action domains are a bit buggy still. They did expose some necessary BP stuff though like being able to make activatable widgets non Menu types.

I think the button class got a couple of extra features, like the locked mode and such.

[narrow sentinel]

anyone got any ideas at all on this one ?

(Look at the replied message for the image)
even though I've set max to 2000 mb it seems it's not using it or something

[past hull]

hello,
Why cant I promote to a variable the new anim to play here ?

[sharp tartan]

Is there any fault in this logic?

[sharp python]

No reason, restart 😛

[desert juniper]

due to floating point errors, checking if a float is equal to a value is not recommended

[sharp tartan]

I want to turn my character right just after yaw value is +90 & left while -90 with enabled user controller desired rotation but as my yaw value reach to 0 this should use orient rotation that will continue turn right & left animation after each 90 degree but in my case this is sliding while rotating

[desert juniper]

you probably want to also do >= and <= not just >90, <-90

[sharp tartan]

ok

[desert juniper]

And lastly, you're creating extremely error prone code by having variables for the direction your facing

[sharp tartan]

can you guide me for this logic as i am new in unreal blueprint (learning it from recorded course)

[desert juniper]

no sorry. i don't have time. however whatever source your learning from looks terrible if that's what you learned to do.

[past hull]

still not possible 😭

[sharp tartan]

okay, thanks!

[desert juniper]

apologies i don't know of any good blueprint learning sources.
The ones I've seen tend to be taught by people who are also beginners and don't know best programming practices.

[past hull]

seems like animation asset is not a valid type

[sharp tartan]

okay

[sharp python]

It's not a thing

It's a sum of things

You can put a lot of different data types in there

Pick one 😛

[past hull]

So I changed to Play Animation Montage but it seems that I cant play 2 animation montage like this. Only my first one is playing. Is there a way to do that ?

[gusty shuttle]

Quick question: How does one possess a character from an actor class? Context, I'm inside the player controller, ensuring my controller possesses the right character

[frosty heron]

It's asking for a pawn but you are passing actor.

You can cast if the actor spawned you spawned is a pawn

[gusty shuttle]

@frosty heron I'll look into it! It will be a Character class that I'll be possessing (pawn), so it should work. I have two different characters, I'm trying to make sure the right controller has the right character

[sharp python]

Hmm

?

[past hull]

i dont understand

[dark drum]

You can only play one montage on an anim slot group at once. To be able to play multiple montages at once, you would need to make multiple slot groups and the montages must be using a slot from different groups.

What are you trying to do? Just a weapon fire animation?

[sharp python]

Both of them will play at the same time and the second one will try to play twice

I assume the goal is to play them in order?

[tight pollen]

Hi, How would you create a group? in PlayerState?
create an Array variable that stores the Player State of other players?

or GameState

[shrewd tiger]

Hi guys
any reason this doesnt work?

[tight pollen]

Create Widget

must be

[shrewd tiger]

thx

[past hull]

oh ok I didnt know that ,thank you

[past hull]

not really, at the same time

[tight pollen]

someone?

[past hull]

and yes, I have an animation for my FPS arms skeletal mesh, and another one for my Weapon mesh

[shrewd tiger]

still no

[tight pollen]

player A invites player B to the group, and I don't know what to do next 😄 how to store this variable and where, on each player Array with group data, or some manager, or Game State?

[tight pollen]

where you creating this widget?

PlayerController, HUD?

add breakpoint to Add to Viewport and check if called

[sharp python]

You need different groups (and an ABP that supports them)

[primal crown]

a stupid thing anyone know why player? would be ticking upwards all iv i need to do is enableing Multicast and this happens doesnt matter where and like this is all i really do

the first line of code is just in event begin

[shrewd tiger]

HUD

[shrewd tiger]

it's called

[faint pasture]

Start with the data. Do you currently have 2 yaw values somewhere? (Upper body and lower body)

[faint pasture]

Your problem lies in the assumption that PlayerController 0 is what you want

Gate that by LocallyControlled

and also get self's controller, not PlayerController 0

Also for clients, the serverside version won't have the mouse location, and the clientside version won't be able to call a multicast

Keeping multicast (which is probably not what you want), you'd set it up like this:

Tick -> locally controlled? -> yes -> send data to server (run on server event)

Run on server event -> multicast

Multicast -> ??? -> profit

but that's gross, what exactly are you trying to do here?

[vivid quarry]

Is there any way to output a variable's value FROM a control rig node for use in another BP?

The output pins, when checked, just seem to act as inputs...?

[jaunty solstice]

Any experts on Animation Blueprints and modifying the City Sample Crowds ?
I'm trying to get the City Sample crowds to animate by default in the editor, without entering PIE.
Does this invlove modification of the ABP_Crowd Animation Blueprint or?
Can anyone point me to good resource(s) for mastering Animation Blueprints?
Thanks!

[primal crown]

yeah i fixed it https://cdn.discordapp.com/attachments/1023663325793501214/1287902010988826725/2024-09-24_00-22-14.mp4?ex=66f33bb7&is=66f1ea37&hm=6b651834bd846e180638e8f49d1faccd3ca151e06c518c18aee27c04143e4f0f&

but originaly what it only thing that i wanted to be sent both ways was debuging purpuses so was just so confused why it would "++" the second Or well in case of more than just one person on a server

[mellow pike]

yeah im setting up a a equipment system with color changing options as of now I have for skeletal meshes to act as each slot (head, arm etc)
when changing equipment I set the mesh and create a dynamic material instance and store it into an array of for elements (to line up with the slots)
then when changing color I use the array elements to change settings.

when changing gear I overwrite the old array element with a dynamic material instance of the new item.

in this context I assume garbage collector will deal with the old elements?

[empty marten]

Hey peeps,
Question time, is there any easier way to change the style of a button than doing it like this? I'm just changing the image but this seems a bit extreme.

[faint pasture]

set elements in struct

[empty marten]

Thank you 🙂

[night dust]

I am working on a chess-like game and I want to have some board squares change colors each turn in a sequence. I have a movecounter int in GameMode which is incrementing fine, and SquareColor variable in the SquareBP which points to an enum of colors. That's instance editable and exposed so I can change each one manually now via the dropdown. I can also use the select node to expose them before the set SquareColor node. There are about seven colors to scroll thru in sequence. I can't seem to find a way to use the move counter to change the enum index and set the SquareBP variable. Of course the move counter will have more than 7 in it so I also need to loop thru the enum, which I understand is a modulo function? The board squares are already defined and draw by a grid of X,Y numbers and I also have an array of those number coords of the square I want to change. I'm thinking I have all the pieces? I'd post up some BPs but they are speghetti mess of failed approaches. Can anyone help me outline the steps/nodes I should use to achieve this result? Pretty Please 🙂

[frosty heron]

When nothing else referencing the variable, it will be garbage collected.

If you point your pointer to other object or null ptr and there is nothing else referencing that object.

They will be garbage collected.

[crystal wharf]

Could someone help me with a dead space like health bar? I've got a rough on put on my player but can't figure out how the material can read from a blueprint i created

This being my bp for the function

This being my material

[silent parrot]

Hey all, for some reason after modifying a good chunk of my blueprints, whenever I play my game to test it, it doesn't crash unreal but everything freezes up and I can't get out or stop the game. It almost seems like an infinite loop that doesn't get detected to exit. Has this happened to anyone? Maybe Event dispatchers that have failed silently causing the game to lokc up? Any insight would be helpful.

[amber fiber]

Hello! I have a simple problem. I want my character to change rotation to 'camera view forward' when aiming, and go back to being able to run around afterwards. I will show my current set up, but I cant figure it out, it seems so simple though

I can get the character to look in the camera forward direction, but the character loses their world rotation by overwriting it to change the direction. I am trying to stash the original rotation before the change, and then add it back after, but it still causes issues. is there a better way to do this?

I tried looking in the lyra project because they do the exact same thing in there, but I couldnt find where it was being handled

[dawn gazelle]

You can add a vector parameter (hold V and click on your material blueprint) to your material which will act as the color parameter and you'd multiply it with your base and emissive channels. Give it a name like "Color". You can keep everything else in your material the same.

On Begin Play of your character, get a reference to your mesh that has the material you want to manipulate, and from it call a "Create Dynamic Material Instance" node, setting the index value to the index of the material on the character that has the parts you want colored - you do not need to set a source material, it'll grab the one already set if it is left blank. Promote the Return Value from this node to something like "HealthBarDMI" - this will now be your reference to your manipulatable material in your character's blueprint.

Within your game logic, you'd then get the "HealthBarDMI" and call a "Set Vector Paramter Value", feeding in the desired color and making sure you set the name on the node to what you've named it in your Material. You can call this whenever the health value changes.

[silent parrot]

I keep getting these errors about an infinite loop and I don't really know how to make sense of where the loop is coming from exactly.

[amber fiber]

UMG_InventoryGrid, and UMG_Item

clear the one out of UMG_InventoryGrid and itll probably fix it

[silent parrot]

Always seem to find it as soon as someone replies haha. Thank you for the help. I'm still not sure how this is an infinite loop however.

[amber fiber]

somehow your item is referencing the inv grid, and the inv grid is sending that reference back to the item

hence the +1000000 hits

[silent parrot]

Somewhere here maybe??

[amber fiber]

it might be something like a variable is being set by both parties

check your set variables

[silent parrot]

Is there a way to identify at least the variable name or type?

Still learning, I'm sorry. But thank you for your help!

[amber fiber]

well, youre running a loop, which will run multiple times, setting those variables each time. so id probably try just removing each set variable at a time, and see what gets the project working again

[silent parrot]

I'll try that now and see whats up

[amber fiber]

i really dont know which one it would be

but thats howd id start lol

[silent parrot]

AH

[amber fiber]

did that work?

[silent parrot]

Youre a life savor omg

[amber fiber]

lmao congratz

[silent parrot]

I needed to add a for loop with break!

[amber fiber]

ahh the loop was looping too hard

[silent parrot]

Dude I'm always so skeptical about requesting help from here but you gave me all the reason to be invested. Thanks bro you helped a ton!

[amber fiber]

yeah its usually hit or miss

[silent parrot]

I'll need to look a bit deeper into the code. It seems a handful of things aren't working as expected so I guess it's just debugging time.

[amber fiber]

your project or someone elses?

[silent parrot]

Mine. Making a game and working on the inventory system at the moment.

[amber fiber]

nice

I did a experience bar and basic skilling system recently for my game

[silent parrot]

Oh thats pretty dope. That sounds like it could be a bit complicated to me. Does it work well?

[amber fiber]

yeah it works, pretty simple though. was kinda difficult to set up but eventually figured it out

[silent parrot]

What kind of resources do you use as your are working? I'm an animator/ mocap guy learning how to program. Does anything help as far as resources or learning material beyond youtube?

[amber fiber]

Im a vfx guy, with a little experience in everything. took coding in college and bombed it, relearning it now lol

[silent parrot]

Oh very nice. Sounds like my story haha.

Gotta head to bed now. Thanks for the help again but I sent you a friend request!

[gentle urchin]

Just stay at it and it'll come to you

If you're willing to learn, ofc

[woeful pike]

Even though I have my map setting to map one. Upon initial loading the file it always loads the default untitled map (Which contains all of Map 1 content) even though my map project settings are all set to map 1. Any way to fix this so that when I load up it just auto loads map 1?

[cerulean cape]

Hi, I have a spline static mesh road that has some degree of roll per point, was wondering how do I take into account of guard rail roll with respect to the static mesh road? Both guard rail and road have their own meshes

[fiery moon]

I'm not sure how you implemented it but PCG is basically perfect for these types of scenarios.

[uneven girder]

Hello ladys and gents, i posted a question regarding blueprints and VFX in #visual-fx

I would apprechiate some of your insight for those blueprints

[lunar sleet]

Is it particles or is it projectiles?

Those are different things in this engine

Also, realistically Niagara > Cascade

[uneven girder]

Niagara particles in the form of mesh renderes

[lunar sleet]

Ok then #niagara is a better spot to ask for particles instead of vfx

It’s a good question tho, something I’ve been wondering about as well. My guess is there’s a way but I haven’t found it yet

[uneven girder]

There defenetly is a way

I am at a point where i can apparently read out collision states from my particles, but i need to set objects ingame to be able to collide with them, since it is pretty much every object, i am kind of lost at the moment in how to do that

[tight moon]

Still unsure atm how to trigger an input only when grabbing an object. Namely, I suppose the bp should be separated between the object and the player bp, but I don't know how to connect the 2...

[dark drum]

What do you mean by trigger an input when grabbing an object?

[tight moon]

So
I need to trigger an audio file while grabbing an object. So, while grabbing said object when I press a specified input the audio plays, however if I press this input while I'm not grabbing anything nothing must happens.

[dark drum]

So it sounds like you want to 'Use' the item you're holding?

[tight moon]

You can say it like this.

[dark drum]

Make a 'Usable' base class for you're grabbables. Add a function called 'Use'. When you grab them, store a ref to them. (as the usuable base class type) In youre child grabbable, override the 'Use' function and play the sound you want.

In terms of you're input, when it's pressed, check if the grabbable ref is valid, if it is, call the 'use' function.

[fiery moon]

Rather then a base class, make it an interface

[tight moon]

Sadly, I have no idea how to make any of them :/

[dark drum]

The best option would actually to use an actor component. Explaining how to setup and use actor components to someone new can be a fairly lengthy process though. As for BP interfaces, these can result in a lot of repetitive work and become a nightmare to manage when you scale up a project.

[fiery moon]

Hmm, yea I suppose actor components are quite good too, and possibly more obvious to setup. My mind just jumped to interfaces after your baseclass idea :P

Whether its ActorComponents\Base Class\Interfaces they all sorta work the same, you see if the held object is of that type \contains that type, and call a use function. (ActorComponents may be able to implement more logic but I dont think that's that great an idea)

[devout tide]

Actor components seem like the go to solution here. You can include specific logic for the system within it and reuse it across different blueprint actors without having to inherit a specific base class. The downside of using an interface is also how much you can extend it, since an interface only provides functions while a component can include a bunch of logic with it as well, if required. This seems like a simple use function, but in case you would need more logic later on, a component would be better.

For example, maybe this Use function later on extends to other usable actors with different functionalities than playing a sound, and maybe with specific filtering for when it can be used, if it's a trigger or hold interaction and so on.. In such cases, a component is good. If this is a sound only thing, then maybe it's not worth the effort

[tight moon]

Sound only thing. Tho it all got more confused to me with my barebone knowledge for Unreal coding... I have this atm, I tried to see hwo it'd work with the overal and I presume it's not properly placed. After that, that's the moment I get stuck on.

[dark drum]

So in this example, you set the bool before you go to the branch meaning it'll always be the option that's set. The overlap will always trigger the sound while the input action won't ever trigger it.

[tight moon]

So, now it triggers, but it only happens once. And in the end, it'll have to be on grabbed, not on overlap 🤔

[devout tide]

Does having input like this in the actor even work? I suppose a more proper holding/releasing system is needed. But in the case above the bottom input should just directly connect to the second branch

Yeah it triggers once cause you set it to false after the input, don’t do that

[dark drum]

How do handle grabbing an item?

[steady night]

hey is there a way to use a button reff to call "on clicked event " ?

[devout tide]

Not from blueprints at least, but you can make a button widget of your own and have a dispatcher there be called from its button click and then also being able to call it externally

[tight moon]

VR basic stuff, this bp is currently in the VRpawn and the object is a BP with a grab component.

[dark drum]

I would just go for the hierarchy root for now.

If you want to store the held item as an actor you can just cast to the useable class. This just means if the item isn't usable, the cast will fail and won't do anything.

[tiny wing]

Hi! I'm having issues with saving a soft ref to a level as variable in game instance. Somehow, as soon as I load (async) new level, that variable is set to None.
I've double checked, it's saved into game instance correctly, it's a new variable, with no other SETs.

All other variables stays at the correct value, which means that game instance is not reloaded/reseted.
Type of variables is World Soft Object Reference -> I've checked other vars like this, and they are all none..

And ideas? I tried to check the variable as transient, but that's not solving the issue.

[dark drum]

How do you set it to save?

[tiny wing]

I'm just setting it, here you can see 2 variables, soft reference is cleared out, data layer stays saved.

[dark drum]

How is 'CurrentLevel' set?

[tight moon]

Really sorry, but rn it sounds even more convoluted for me. What are these BPs, usable and soundbox ? Where is this inputaction located ? Where is that Parent-use function from, can't replicate that..?
It's really not fun to drag this porblem for this long, but I just don't understand how this all works.

[tiny wing]

In level01 -> there's a BP_Gate, with CurrentLevel hardcoded right now.
Then this saves those 2 values in Game Instance, and load a minigame.
As soon as I'm in minigame level - I did a breakpoint on gameinstance, and all variables are set correctly, just WORLD SOFT OBJECT REFERENES are set to None.

[dark drum]

Hierarchy is the backbone of object orientated programming. It might be worth you reading up on it.

BP_Item_Base is a child of Actor.
BP_Item_Usable is a child of BP_Item_Base.
BP_Item_SoundBox is a child of BP_Item_Usable.

The use function is in the BP_Item_Usable class.

[tiny wing]

and LoadLevel from GameInstance is simply:

[dark drum]

It doesn't seem like you're actually saving/loading anything. Once something is unloaded, all it's data is gone. You have to save it to disc if you want to keep it. With the data saved to disc, you can then load it from disc and reapply it where needed.

[tiny wing]

so why all other variables are ok?

I think GC is clearing that type? on a given example you see 2 variables -> data layer, and level soft ref. Data layer is set properly.

But object soft ref is not, GameInstance should be alive the whole time that the game is running, and it seems to be, as other variables stays in the memory, even if load different levels.

[dark drum]

Try using the 'Soft World Reference' for the var type. You can't normally just get a 'World' ref type without prompting to a variable. (doesn't show up in the list by itself)

[tight moon]

I don't know how to get Use function in the Soundbox bp...

[maiden wadi]

Gamepad input still? 😄

[dark drum]

If you've added it to the parent class (the usable one), override the function.

[steady night]

yepp 😛

[maiden wadi]

What do you need to call it directly for?

[steady night]

well i have already alot settup and would take days to remake it for that reason just use the click function would help allooot

[maiden wadi]

But I mean like usecase wise. What do you need to call the button's clicked for?

[tight moon]

After that, where do I put the input code ?
Also the grabbable objects are already in the scene, and they need to have the audio available as an array in their detail, so idk if this will still allow them to work properly regarding this.

[tiny wing]

Well, that's strange - as soon as I set the blue one, the light blue is also set. But when I do not set the blue one, its not working.

[devout tide]

You can’t

[dark drum]

I put the IA_Shoot (replace with whatever IA you want to trigger it) in the player character (I assume you grab logic is in here). I would imagine you have a variable in here that is used to store what is currently being grabbed.

[dark drum]

UE is very specific about world references lol.

[tiny wing]

anywya, thanks. finger crossed it will work also after building ;d

[tight moon]

What's that Get node btw ?

[dark drum]

That just a normal get node but converted to a validated get. (Right click on it to get the option)

[tight moon]

I don't know how to have that get node to begin with...

[dark drum]

Just drag the ref into the event graph.

[tight moon]

... what ref..?

[dark drum]

To the thing you've grabbed.

[tight moon]

That doesn't exist in the VRPawn. It's in another BP.

[dark drum]

So the logic for grabbing an object isn't in you're pawn?

[tight moon]

Wait I may have found smth.

[tulip totem]

I want to make a click to move control scheme where if you click you move to location, if you click and drag you rotate the camera.

I have the click to move working with a double click
click and drag for camera movement

problem occurs if i only use a single click to move, sometimes you might start moving when really you were wanting to drag the camera.

i'm also thinking this might happen when you click on a UI button, it may move somewhere at the same time.

How do you check your clicks for 1 - making sure it is a click and not turning into a click n drag. and its a click not UI related?

[tight moon]

@dark drum got this now

[dark drum]

Show how you handle the grab logic.

[tight moon]

The basic UE5 bp.

[calm cargo]

Anything I can do to auto organize this kind of mess without wasting 2 minutes of development time that doesn't actually add to the project?

[dark drum]

Organized code does add to the project. It improves long term efficiency. 😉 As for auto methods, no, you have to organize it yourself by using reroute node, functions or collapsing nodes.

[calm cargo]

Aight, shame there's no automatic script or something

since whenever I organize stuff I feel like I'm on auto pilot anyways

[dark drum]

You can select nodes and press 'Q' to align the exec pins. That can help speed things up.

[tight moon]

@dark drum there you have it.

[tulip totem]

think i solved this with enhanced input action and "tap" trigger, seems to work fine.

[dark drum]

I just created a VRTemplate project so I can see it lol.

Ok, so it looks like it finds grabables by using a 'GrabComponent' so you can get the owner which will return the BP the component is on. You can then cast the owner to the usable BP and call the function.

[tight moon]

So, the input works, but it doesn't seem to play anything.

I'll just add that I skipped one of the child bp, I just have the grabbable object one and the sound one atm.

[dark drum]

Did you override the 'Use' function in the sound one?

[tight moon]

Here's everything.

[dark drum]

Have you set the sounds in the Notes Audio array?

[tight moon]

On my actual pc I can't hear anything, but at the very least, the final string doesn't get printed.

[dark drum]

Are the objects you're grabbing this type of actor?

[tight moon]

Well... nope. Would it still work if I put this all in the Objet instead ?

[dark drum]

You could reparent them if they are just a child of actor.

[tight moon]

Seems like it's finally working just in the BP_Objet !

That was tough but I think it's over.

And normally it should play specific audio for different objects.

Thanks a lot for the help and sorry for making it longer than it should have 😅

[copper chasm]

"don't put it down, put it away" is my number 2 rule in blueprints i swear to my coffee

[tiny wing]

Bumping up, turns out that's still not working

[dark drum]

Try creating a setter function in the game instance to update the variable instead. See if that makes a difference.

[tiny wing]

tried already, no difference

[devout tide]

did you check if the level is packaged or not?

[young meteor]

Is it not possible to "make class" like I would be able to with "make literal text" etc. ?
I basically want to spawn a random actor from a list of 5 I define myself.

[devout tide]

You cant make a class like that, no

if you need a random actor, you can make an array of actor classes and get a random from it

[young meteor]

Thank you

[young meteor]

Thank you.
I did it like this because I need to know which one was chosen for further calculation.

Guess your "Random" node has an index output though.

[devout tide]

yes that int would work but theres something to be careful about, a pure function is called every time you are using it, so if you are getting the class and integer, it would most likely be different random values

so you need to promote just the int to a variable, then use that and for the class get it with a get usnig that saved integer

[young meteor]

I see. Thanks for the heads up. 🙏

[devout tide]

like this

[young meteor]

Got it.

[devout tide]

while this could be different values between class and int

[young meteor]

🙏

[copper chasm]

I’m creating widgets from an array of names, and I want to fill a uniform grid with them as they’re made - I already have the uniform grid sitting waiting to be filled, I’m just not sure how to fill the slots from the indexes so it is the structure I want (4 columns per row)

[timber knoll]

Your not sure how to generate the indices?

Or how to use the indices to get column/row?

[devout tide]

like this

but with your widget

so divide and mod the index with the amount of widgets per row, then add to grid to its row/column slots

ignore the data table stuff

[iron idol]

clicking text in button is preventing the actual button from being clicked. Anyone know whats causing this?

[timber knoll]

That's somewhat weird tho

[devout tide]

try setting it to this

[timber knoll]

Typically you would fill columns left to right first

[devout tide]

no its not, this is left to right

[timber knoll]

Oooh lol yeah I can't read

[iron idol]

nevermind I apparently somehow dragged the text out of the button

[devout tide]

right, makes sense since normally even if its visible, if its under a button it wouldnt block it like this

[maiden wadi]

Do you need the grid, or just to make it look like one? Cause a WrapBox or TileView inside of a Sizebox in a will make life easier.

[jaunty solstice]

Any C++ Blueprint wizards able to tell me if there is any performance difference between implementing editor tick via Blueprints or via a custom C++ class?

[devout tide]

C++ tick disabling will completely remove it from the ticking list compared to blueprints, which will check it but simply skip if not tickable

Thats why cpp says "will ever tick" compared to the enable/disable blueprint gives you

so disabling from C++ is better

[timber knoll]

C++ is always faster

But it's a question of do you need it to be faster?

[iron idol]

If I wanted to give a random unit a random array item, is this how I would go about it?

[devout tide]

For an exposed variable it actually doesnt matter, if ever tick was exposed to blueprints and you would disable it there, there would be zero difference

cpp code is faster, setting default variable values is actually the same

so right now you are having him a random weapon of his weapons?

[iron idol]

I'm trying to give him a random weapon

[devout tide]

but the random is taking from his owned weapons

[iron idol]

oh hahaha

you are right

i see what you mean

[devout tide]

make a different array or whatever makes sense in your case

[iron idol]

so the items are not of an array class. do I have to make another one of them

another array that is

or can I just get all actors of class

like would this be fine

[devout tide]

that gets all actors in the world, which is probably not what you want

[copper chasm]

I reckon I might could try those, I figured grid would be easier as the number of widgets I’m making to fill it will grow

[iron idol]

yea i also just realized that as i sent it

[devout tide]

instead, make an array of classes somewhere and do it from there

[maiden wadi]

Wrap box is literally designed to simply show widgets in a straight line left to right, but wrap to the next line when it hits it's allowed bounds. Basically like a textblock with text wrapping. Tileview does the same, just with virtualized widgets.

The only reason you'd need a grid for this is if you need the widgets to show on specific grid points. Like 1, 2, and 4, but not three. Like older inventories.

[tight moon]

Big problem now : this entire code doesn't work. It used to, just this morning, but now it doesn't.

The trigger does nothing to begin with, no idea why.

[steady night]

hey im sing "on hovered(button) " from a parent owning widget but it dosent detect it on the child "onhovered" ideas ?

[copper chasm]

My only query with the wrapbox is spacing, I’m not super familiar with padding and whatnot when generating content this way (as opposed to manually putting it in) - I can probably figure it out though

[timber knoll]

Make sure you have parent node too, if not: rightclick on the node and add parent version

[steady night]

dosent work mby since its a widget class or ?

[steady night]

(as u can se the "add call to parent function is grayed out)

[devout tide]

because theres no parent function call

what are you trying to do here?

[steady night]

well i ive set another parent for the widget and im tring to use the "on hovered/de hovered" on all children with the same event

instead on putting it on each wdget (i have about 50)

[devout tide]

but parent widgets dont share buttons

just custom events, functions and varaibles

so you need a custom event and then call it on hover

[steady night]

yeah but when i hover the parent wb it dosent detect the hover on the child on

e'

[devout tide]

thats because as said, the buttons are difference so their hover events are also different

[steady night]

when i hover on the child it dosent detect the hover

aye,

[devout tide]

make a function on the parent and call it for all the hovers you need, manually

[steady night]

ah yeah so on each widget i can to use the honver / unhover event right ?

and use same parent event

thats what i was planning but would save time if it could be combined somehow

[devout tide]

cant be but you can make a generic button widget you reuse across your widgets, like a library of them

[steady night]

aye

[frozen wren]

for people that understand how array work i have array items = 4, i want the max number to be = 3, if i add new array item ,i want to remove the first added items

[proud bridge]

hey why is this not working? the emitter is not getting destroyed

[glossy cloak]

Whenever you add something to your array, first check if the length is < 3. If it is, add to it. If it isn't, remove index 0 and add to the array like normal.

(Edited because I just woke up when I answered the first time and I gave a confusing solution. Lol)

[jaunty solstice]

My goal is to enable the City Sample Crowds with animation in Editor.
So as a first step I need the spawning functionality to work in Editor.
This translates to adding Editor Tick functionality to the crowd spawning blueprint.
But when I open BP_MassCrowdSpawner there is no functionality in either the Construction Script or Event Graph.
The parent class is "Mass Spawner"
But where is this Mass Spawner class located? I can't find it anywhere in my project!

[glossy cloak]

In which case you'd probably rather remove index 0, then add the new item.

[glossy cloak]

Are you destroying the actor that code runs from on that first sequence branch before it has a chance to?

[glossy cloak]

It's probably a C++ class.

[proud bridge]

hmm let me check, thnx

[proud bridge]

u were righttt omg, jst decreased the delay value, the whole actor was getting destroyed after 3s, so the logic wasnt getting executed

[glossy cloak]

Ha ha we've all been there.

You could also promote that emitter* to a variable, then override your "onDestroyed" event and destroy the emitter there. That would ensure that it was destroyed when the actor was destroyed without needing any delay timing.

[spark steppe]

most likely in the Unreal Mass Plugin. i can't tell for sure, but maybe the spawn asset just defines the spawn rules and the mass spawner runs regardless

[proud bridge]

hmm, for MP this is absolutely necessary. am I right?

[glossy cloak]

If you click on your actor details in the top right it will say the parent class with a wrench icon next to it. Clicking that will open the blueprint or C++ class associated. You'll very likely need to change the functionality in C++ in this case though. Good luck!

[glossy cloak]

Not "necessary", but it kind of depends on how you're removing the actor.

[proud bridge]

totally destroying then respawning

[frozen wren]

is there a way to get earlier added array items

lets say i have 10 already, i want to remove the first 7 items and remain with 8, 9, 10

[tight moon]

Posting it here because I really need some help : a trigger node that worked fine this morning justd ecided to not work at all now. The hand is animated, but anything that must happens from it just doesn't. I really need help to know what messed it up, there's no reason for it to be broken at first sight.

[frozen wren]

and when i add 11, i remove 8

[torn relic]

The Boys is the best series, I just finished watching it today 😉

[glossy cloak]

I meant more it depends on if the server is destroying it or if clients are waiting for the server to destroy the actor or something. If it's all handled on the server and it's a replicated actor then it won't really matter when the server destroys the actor or the particles. The clients will also eventually destroy it.

[glossy cloak]

Oh. So a reverse for each loop and remove each one until the index in the loop is < 3. Then break the loop and add the new item like normal.

Oh wait.

[glossy cloak]

So.... You just want to add the first 3 of the 11? Is that what you're trying to do?

I don't see why you'd add 11 if you're just going to remove 8 of them afterward.

Instead, just trim the new array of 11 down to 3 then set the old array to that new array of 3.

[glossy cloak]

Share the code so we can see what might be wrong. Or throw a breakpoint on your overlap and see where it's failing.

[tight moon]

That's the code

But there's nothing wrong.

It worked this morning and nothing has been changed to it.

[glossy cloak]

Ohh.. that kind of trigger. Lol

Right click and put a breakpoint on the first node. Test the game and step through the code. Step into each function to see where it's going wrong.

[glossy cloak]

For starters, you're setting your right arm to itself for no reason.

You can simply remove that entirely.

[jaunty solstice]

Thanks!

[tight moon]

The issue literally happens right after the enhanced input. Nothing comes from it.

[glossy cloak]

It doesn't trigger?

[tight moon]

It doesn't do anything !

And yet ingame when I press the trigger the hand still moves when pressing it.

[glossy cloak]

So.... It is working?

I guess we need more information then. Did your breakpoint not trigger?

[tight moon]

No idea what happened. Now I have 0 idea what the breakpoint does, but how it goes now is that if I press the trigger, the finger of the hand mesh moves AND it SHOULD create a laser, but there's simply no laser, only the animation. Putting a print right after the input just shows that the print doesn't even appear.

[sinful pawn]

Hi, does anyone have a good tutorial on how to implement voice proximity chat with reverb wall oclusion etc... using the steam subsystem ?
Or does the subsystem doesn't matter ?

[glossy cloak]

So you didn't try the breakpoint?

A breakpoint pauses your game when the node it's on is triggered. You can then use the controls on the top center of the screen to step through the code one node at a time to see where it does something unexpected. If it just unexpectedly ends and goes back to the game then it likely failed a branch.

[tight moon]

Breakpoint doesn't work on the node.

I tried it on another one and yeah, it paused. But not with the trigger.

[glossy cloak]

Do you have another input somewhere triggering this maybe?

[tight moon]

Nope.

[glossy cloak]

Did you add this input to your character's input mapping?

Maybe you did that last night but didn't save it?

[tight moon]

No, it was just working this very morning !

I haven't touched the input until after I saw it not working.

Could it be related to the MetaXR plugin ?

[glossy cloak]

I have no idea. Did you just add that?

[tight moon]

I used the most recent version, and after that it broke.

Reverted it, still doesn't work. I'm out of options now.

[glossy cloak]

Did you double check your input mapping?

[tight moon]

Yep.

[glossy cloak]

Your hand moving is controlled from a different input action right?

[glossy cloak]

Maybe delete that input node and add it again.

Are you getting any runtime errors?

[tight moon]

There's no error message.

I tried using another input action using that same input, it did nothing.

Gtg now, so I'll check it more tomorrow ig...

[tulip totem]

I have a simple trigger box that plays a sequence and then teleports you to the end of the sequence to continue.

it was working fine.

I added nav mesh to change how things are controlled and now the first time you run it, the trigger works. hit escape. run again, the trigger is broken.

edit anything on character and run again, itll trigger first time and then break again. any ideas??

[glossy cloak]

Are you changing any variables the first time around that need to be reset?

[silk hinge]

hey, i'm still stuck with this issue

basically, I control a chaos wheeled vehicle movement component from my player Pawn.

I got a feedback from my player saying the input works, and my cast into the player pawn wont fail at all.

Then my vehicle Actor is also having a feedback and shows that the throttle or the streering is changing values , but nothing happens, why is that ? ( the component is activated and there is an option "bypass contoler need for input" that I also tryed disabling, but nothing works...)

[tulip totem]

turns out my new click to move was spawning a little marker that randomly would trigger the overlap and then it would just fail 😄 i forgot to make the thing only look for the player overlap, or i thought i had done that but apparently not

[glossy cloak]

Nice job diagnosing the issue!

[maiden wadi]

Does input work if you possess the vehicle directly? Cause passing inputs like this is not wise in most cases. The usual is to simply attach your player character to the vehicle and possess the vehicle until you leave it.

[lunar sleet]

any idea what could cause this to fail?

it stays perpetually false, which according to the tooltips means it was unable to determine the value

the node is in the PlayerCon btw

[iron idol]

how would i get a reference to the unit chosen here. I'm trying to get the name, but i think its just spitting out a random name AND the function is running on a different random unit. I tried Promoting to variable but that seemed to just break it.

[spark steppe]

show more of the graph

random get's executed each time you pull from it's result

[iron idol]

yea

[spark steppe]

promoting it to a variable fixes that

if it didn't for you, you got another issue

[iron idol]

hmmm maybe i set the variable before it pulled the unit at random

thanks for the info

[copper chasm]

I know I've asked a very similar question before, but that was last week and trauma happened so I don't remember where I was at and started over - I have this code that creates the widgets I want (A visible button with a non-hit test image on it and text underneath) - the buttons generate wonderfully. I am trying to set up the event construct so that clicking an individual button will grab its flavor text so I can update the text on screen. I am fairly sure I need a ForLoop, but do I need to get all children of the wrap box and then cast to the specific widget type? I'm lost

[iron idol]

should that work?

[fierce birch]

I have an issue that Im encountering, I create and set a dynamic material instance of some volumetric clouds, when it comes time to set some scalar parameter values, it sets them just fine but the values are not being reflected properly for the clouds, if i go into the material instance and change the values manually then the set parameter nodes kind of behave like an offset, i thought its supposed to overrive the value? if anyone can help that would be appreciated thanks

[spark steppe]

no

promote the object to a variable first and then use that stored object reference to get your class

[iron idol]

so before add

something else might be going on then, because I think thats what i had done. I'll try again

[proud bridge]

Hi, can anyone tell me if I can use an animated .gif as an image for buttons in UMG? Will use the gif importer plugin.

[glossy cloak]

Create an event dispatcher called "PressedButton" on your widget. Add an input to it of type "text". When the button is pressed on the widget, under your "onClicked" event, "call" that dispatcher. Plug the description text you want in there.

Then back on the blueprint that spawns the widget, drag off of the widget's reference output pin (or use the widget's promoted variable) and "bind event to PressedButton" That will give you a node with a little red box. Drag off that box and create a new custom event. It'll have the output of the description text and you can now update anything you need with it.

Let me know if you need clarifications on anything.

[iron idol]

so this is still not working. I'm given a random name and the item is given to a seperate random unit.

[glossy cloak]

Each time "random" anything is called it generates a new random.

[iron idol]

is there a way to get the same result for both

[glossy cloak]

So if you want to generate a random anything, one time that you can use in multiple places, you'll need to promote it to a variable once, then use that variable everywhere you need that randomly generated output.

[iron idol]

do i put it directly after random?

oooh

i think i understand

so get a random unit, set it, then choose a random item for that unit

[glossy cloak]

Just make sure you're not triggering the random generation and storing it multiple times, cuz then you're going to get the same result.

[glossy cloak]

There ya go.

[iron idol]

thanks, man

[copper chasm]

That worked, I think I'm doing something stupid with my foreach loop, because it only works on the last button, but that's a whole other pile of worms

I didn't even consider storing the flavor text in the widgets themselves, I was trying to do it in the "outer" widget that housed them

[glossy cloak]

Not sure what you're doing a for each loop for or if it's unrelated. The dispatcher should allow you to get direct information without having to loop through your buttons or anything.

[worldly dew]

Hello, i have encountered a very weird issue: in UE5.3 I basically have a blueprint that rotates the player character using a timeline, everything works perfectly, but if I call the event using an AnimNotify, the characters rotation is instantaneous and the screen jitters for a split second, while if I call the same event in any other way (for example, by setting a timer and then calling it after playing the animation), this behaviour doesn't appear. I have even replicated the same error in UE 5.4, on fresh project, and it behaves the same way. I already tried a lot of different ways to implement the smooth rotation I want, and every single time calling the event from the AnimNotify causes the same problem

[copper chasm]

I'm looping through an array of gameplay tags to make the buttons in the first place

[glossy cloak]

Yeah! Try to put relevant information where it makes the most sense. If each widget/button has different detail information, then they should each have those stored. Or you can use a data table for it all, then use an ID or something on each widget to grab that information. Then you'd just input/output the ID instead of the description/flavor text itself.

[copper chasm]

For each tag, I convert it to an FName and use that to pull all the info off a datatable, which I use to make the widgets - that works, but I'm assuming I need to populate another array with the created buttons or something

[glossy cloak]

Are you using a notify state?

[worldly dew]

Just a basic AnimNotify, it calls the event on the player character blueprints and then returns

[glossy cloak]

Well that's odd. Toss a print on the Attack Rotation function start and see if it's being called multiple times maybe?

[worldly dew]

Already tried, it's only getting called once

[glossy cloak]

Well that's a mystery then...

Is your animation root motion?

Maybe it's conflicting with your manual rotation?

[worldly dew]

I wish it was, but there's nothing wrong with the rotation if I don't use an AnimNotify

[glossy cloak]

Right, but are you playing the rotation during the animation in other instances?

I assume the notify is triggering in the middle of an animation.

[worldly dew]

I replaced the notify with this after playing the animation, I have lined up the delay with the moment when the notify was getting called

[glossy cloak]

And that works just fine, huh?

[worldly dew]

Perfectly fine this way :/

[glossy cloak]

Looks like you could ditch the player character cast and just use that message node instead. Though I don't think that's going to change anything.

[worldly dew]

Yeah, originally it was that way, i'm still debating wether to keep the interface or not

but as you said, it doesn't really change the output, i tried that already

[glossy cloak]

It's just the only thing I saw that was even slightly different between the logic, but logically, it shouldn't change anything.

[worldly dew]

It is kinda hard to see in the recording, but this is what happens while using the AnimNotify

Also as you can see from the print string, the rotation gets called once per attack

[copper chasm]

I misunderstood what you had originally said, I was trying to do a for each on the buttons a second time in the onclicked for some reason and I was getting each individual button's flavor text instead of passing it in with the dispatcher - there's an hour of my life I'll never get back sad trombone noises

[glossy cloak]

Lol if it only costs you an hour to learn a solid lesson about a better way to do something then you're well on your way.

[silk hinge]

yeah the pawn class vehicle works super well

But my project is making players able to control a vehicle, while controlling there main character into a full FPS, so it's not really an option, I got too many systems with aim offset and separated upper / lower body

[flat pike]

Hello everyone, I'm new to Unreal Engine, and I was wondering if anyone knows of any tutorials for creating a grappling hook mechanic in a 2D side-scrolling game. Unfortunately, all the tutorials I’ve found online are for 3D. Any help would be greatly appreciated

[storm solar]

I'm trying to make a 2.5d action game like in the video below. I have a good amount of setup so far and am now working on a dynamic camera.
I have the camera zoom in the closer the player is to the target, but that is all I have so far.
How do i set it up so that the camera will move and rotate to the same axis like in the video below?
https://youtu.be/W9-TZCN1bpU?t=218

[dark drum]

What does 'Attack Rotation' do? Hows it implemented on the character?

[worldly dew]

This is the blueprint

However it works perfectly when i'm not using the AnimNotify

[maiden wadi]

I don't know what that means. I assume this is something like Farcry's vehicles where you can look around in FPS mode and shoot?

[dark drum]

I like to make sure I can see the whole picture. 🙂 You'd be surprised how often bugs can arise from things you don't think are related. lol.

But yea, I can't see any issues with that. You might want to account for the camera rotation at some point though for the target yaw. 🙂

[dark drum]

Does the BPI event get called anywhere else?

[worldly dew]

I checked with a print string, it only gets called once when it needs to

the code is supposed to do some simple rotation during an attack animation, like in souls like games, the camera doesn't need to move. In fact, it doesn't when i'm not calling the event with the AnimNotify

If I call it from the gameplay ability that is playing the animation it works perfectly

[dark drum]

Odd, hows the notify in the montage? Is it overlapping with any other notify events?

[worldly dew]

There is another one two frame later, but I already tried moving them around, and when i reproduced the issue on a clean project I only set up one notify in the animation

Also tried using a notifyState instead of an AnimNotify, just in case

[dark drum]

You could try changing the notify tick type to 'Branching Point' to see if it helps. Probally not the cause but worth a try.

You might as well check the Trigger Weight Threshold as well in case it's a blending issue. It should default to 0.00001 .

[copper chasm]

I think I screwed something up again - I made a "master button" widget, and I've added that into second widget. The master button has an On Clicked event that calls an event dispatcher for "OnClicked", and I'm trying to bind to that in the second widget. Should the second widget just be a child of the master button, instead of adding it into a new widget?

[worldly dew]

No luck on either of those 😦

[dark drum]

It sounds like it should probally be a child.

[copper chasm]

Word, I'm spaghetti-ing the heck out of myself, and only while typing that up did I think (hrm, maybe I started incorrectly)

[dark drum]

I'm out of ideas. It's an odd one.

[worldly dew]

Same, to me it looks like a bug

[copper chasm]

good news is I'm almost done re-re-re-recreating the base basic character creator, then i get to go into modular mesh building or whatever

[worldly dew]

This is what is happening, it's kinda difficult to see post compression but i think the jittering is visible

As if the camera shifts to something else for 1 frame

And the rotation becomes instant

[dark drum]

Looking at the video frame by frame the rotation looks fine. It's the camera that moves.

[worldly dew]

Maybe it's not evident in the video, but I assure you the rotation is also messed up when the camera jitters

It just doesn't happen consistently

[dark drum]

It definitely just looks like the camera to me.

[dark drum]

Good luck with the modular mesh building. You might want to get a spare keyboard. 😛

[copper chasm]

FOR NOW, I'm using a synty pack thing I got from the humble bundle and it appears to have some code built in for cycling through the assets, I'm hoping that's reverse engineerable with minimal effort

nobody wants to play my RPG where everybody is a cube 😦

[vapid plank]

has anyone had issues with blueprints giving different behavior in different editor sessions? My code was producing result A and now it is producing result B. I am on the same source control commit where it produced A. Very frustrating and puzzling

[dark drum]

What's producing result A/B? As a guess it could just be a change in the load order, hard to say without knowing more about the code/logic.

[dark drum]

That depends. Minecraft is a very blocky game. 😉

[copper chasm]

minecraft is an rpg like uno is a casino card game 😛

[vapid plank]

In blueprints my player character inherited from Character. The character was not rotating with the camera. Now the character is rotating with the camera. I am using source control so I am struggling to see how this can happen. I did not forget to commit anything. Just deleted all the temp unreal files and am trying again

[dark drum]

You've probably ticked, 'Use Control Rotation' in the movement component.

[vapid plank]

that has always been ticked for this particulalr class. What do you mean by change in load order?

[dark drum]

The order actors are loaded in the level but with what you're issue is, it shouldn't be affected by it.

[vapid plank]

thinking now that use control rotation is ticked, makes it even weirder that the character was not rotating with the camera before

[copper chasm]

The print string fires, I cannot for the life of me figure out why the event dispatcher isn't firing

[vapid plank]

i dont think bind the event calls it

i see event construct which looks like UI

is this a UI widget?

[copper chasm]

It is a UI widget

I have the exact same setup in the widget right next to this one

and it works

[vapid plank]

i haven't done this in a while so I don't remember the exact details, but in the widget details you have to specify which function to call for on selected

[copper chasm]

this is some (i'm not sure if I can swear here but it rhymes with wool spit) in regards to me trying to use my "Master Button" widget and not just putting buttons in as I need to use them

I thought I was clever, I am in fact a douchecanoe

[dark drum]

As a guess, you've not populated the heriatage buttons array.

[copper chasm]

on the contrary my friend, WAIT

well, no, hang on

I populate the array on notification for clicking the widget switcher, but the for each is firing on event construct

so yeah, I HAVE populated it, just in the wrong part of the timeline

I'll just pop a sequence on and do it after I fill out the box

effin' A

[copper chasm]

I know what you're talking about, but the dropdown scares me so I always just make custom events off it

[copper chasm]

The funny thing is, I checked it, because I thought it was weird the buttons were getting text from the array but not letting me click them, and it DID show the array was filling, but that didn't matter because it was empty on construct and just moved on with its life

[dark drum]

Easily done.

[vapid plank]

so you're all set now?

[copper chasm]

yeah, I'm pretty sure the sequence solution isn't the most elegant, but it's the most "working right now", so we forge on

[dark drum]

Create a function called 'GetButtons' and add an output that is of the type of you're buttons. Then use a make array node and connect the button refs to the array and connect to the output.

Make it a pure node and boom, you have a getter function to get all you're buttons. 🙂 It should then work on construct.

[copper chasm]

I don't think you liked this when I mentioned it last time, but I have no button refs for my character creator, they're generated and then they go into the array

so as I add stuff to the data tables, the buttons will just make themselves and I don't have to go back into the code in 2 weeks all confused

[dark drum]

Can you not create the binding when the buttons are created?

[copper chasm]

Technically it's shortly after, I make the buttons, add them to their array, put them in their container, and then the sequence runs and takes the array and creates the bindings

If I'm understanding you

[dark drum]

The issue you have with what you showed above is that ever type you click the heritage button, it'll attempt to bind to all the buttons again. It should only need to do it when its first created straight after the create widget node. You can even do it before you add it to a container for it to be visible.

[copper chasm]

I see what you mean - I updated it, although I'm essentially clearing and creating buttons for the container every time I click back and forth from ancestry to heritage so ultimately it's gonna bind every time

womp womp

[dark drum]

You could look at reusing the buttons so instead of just clearing them, you set then to collapsed and then update the text to what it should be and set to visible. (just a suggestion lol)

[copper chasm]

Yeah, we were talking about this before I had to leave town last week - it might be worth looking into down the road, but for the character creator that runs ahead of anything else I don't think the performance is a concern

[silk hinge]

well yeah I guess, you can play normally while controlling a vehicle

[storm solar]

Here is my camera script

[inland walrus]

Anyone know why this is being teleported?

[broken wadi]

Because you aren't lerping anything

Here's how I slide my door down along the Z axis for reference.

the curve on the timeline is nothing special either

[hybrid ether]

Hello! When my player character dies I use remove from parent of my "Main" widget. Main widget have timers and even after it is removed from parent it ticks. Why is that and how I can fully destroy widget?

[faint pasture]

you're setting the relative location of the root component

root is relative to the world

either move the cube and leave the root where it is, or do something else

if you instead move the cube it'll go up and down relative to root which is what you want probably

btw you can make a timeline loop, no need to feed back in like that

[inland walrus]

thanks dude

Any idea how i'd do this?

I need to find somewhere to put the play sound as the sound is playing with the tick, infinite amounts

[faint pasture]

Begin play and make it looping?

when should the sound play

[inland walrus]

The sound should only play when the player is out of breath

so < than 90

[faint pasture]

and should it loop when out or just play once?

[inland walrus]

I need it so that it plays once and stops if the player is over 90

[faint pasture]

what if it's done and they aren't over 90, keep playing?

[inland walrus]

yeah

[faint pasture]

Just add an audio component and set its volume based on breath

[inland walrus]

so loop until over 90

[faint pasture]

Tick -> Volume = MapRange(breath)

[maiden wadi]

I love GAS so much. Out of breath? Need camera work and sounds, etc etc? Apply a GE that has a tag. Tag is associated with a Cue. Cue does everything you need. Gameplay code simply applies and removes the GE.

[inland walrus]

If its on tick it will play sound multiple times and overlap

[faint pasture]

So basically the GE would be a buff representing the fact that you're out of breath right?

What does the application of the GE, is there a rule-based way to do that or are you just checking on tick

[maiden wadi]

Yep. I assume there would be other reprecussions for that too. Maybe it's a 2s GE that also keeps you from regenning stamina. 🤷‍♂️

[faint pasture]

don't play on tick, change volume

[inland walrus]

so play on begin play?

[faint pasture]

it plays all the time (actually stops when volume is 0 but either way)

[inland walrus]

start on volume 0

[maiden wadi]

Out of breath probably triggers at stamina hitting 0

[faint pasture]

There's probably settings to not have to do anything but set volume on tick

add an audio component to your actor and play around with it

[faint pasture]

So a GE that monitors stamina or would that be an auto-casting ability?

GE_StaminaMonitor
GE_OutOfStamina

[maiden wadi]

Hmm. Depends. I mean you could easily do it with an ability applied and activated. Activation binds attribute changes and listens for stamina to hid nearly zero.

You could also put a delegate in your attribute set and run it when stamina hits nearly zero and bind that somewhere to do it.

[maiden wadi]

First one is more modular. Can toss the ability in some game modes maybe.

[faint pasture]

Where's the audio component

[faint pasture]

Can an effect conditionally apply an effect or is the application of effects only done by abilities?

[faint pasture]

Don't set it to 0 ever right now and confirm you can hear it

you should be able to not have to touch it on begin play tho

[faint pasture]

btw your bool sets are backwards

[inland walrus]

Thanks man all working

[thin raptor]

Can anyone help me with a runtime error I'm getting?

[lunar sleet]

Post a screenshot

[thin raptor]

It solved itself somehow 😭

I didnt even change anything

[lunar sleet]

What was it

[thin raptor]

some boolean nonsense

Whats the physics handle variable to adjust if I want to make the box "heavy" so you can't toss it into the stratosphere by flicking your mouse?

[dim halo]

Hey guys does anyone know why a blackboard based condition checking whether a bool is set is failing despite the boolean being true

[woeful pike]

Even though I have my map setting to map one. Upon initial loading the file it always loads the default untitled map (Which contains all of Map 1 content) even though my map project settings are all set to map 1. Any way to fix this so that when I load up it just auto loads map 1?

[queen heron]

how would I be able to make a jump height prediction depending on the Jump Z Velocity and Gravity?

ah pfff, nvm, there's a Get Max Jump Height that calculates the jump Z and gravity

handy stuff 😄 👍

[maiden heath]

Hi Guys I have a problem with Unreal both in Editor and Build I put some Grooms on my avatar but when I start in Editor and Build the hair Flickers every now and then how can I remove this problem? Thank you very much

[oak fable]

adjust the LOD on the LODSync component
for me i set the forced LOD to 2 instead of -1

[maiden wadi]

You can apply an effect from anywhere as long as you can reference the actor and get it's ability system component.

[tight moon]

So, I'm back to my last issue : currently on my vr scene, an input simply refuses to work : I can press it while ingame, the hand will move accordingly but what's linked to it simply doesn't happen, it doesn't even start in the blueprint.

[steady night]

in a ui image im using the auto behavior tic on visiblity is there a way to turn of the tick at a certain stage or something ?

i mean since when its true its collapsed but it will never go back is there a way to turn of the tic also ? i mena it will stay idle always checking (for preformance)

[dark drum]

No, its one of the reasons why some companies ban using those sorts of bindings in widget. (You can even disable them in the project settings)

Instead you would have some sort of event dispatcher that the widget would bind to that when triggered, tells the widget it needs to do something. In you're example, you would have an event dispatcher in the player character that is called when the variable is updated. (You'll probably want to make getter and setter functions so you can set the var to private) The widget would then bind to the event dispatcher and when the variable (in you're case array) is updated, it tells the widget to check if it should be visible or not based on the new data.

[dark drum]

When you say what's linked, are you referring to what's been grabbed?

[tight moon]

Oh hello again 👋
This ain't a grab thing this time. It's the trigger input on the oculus controller. I even tried yesterday to check it with breakpoint, but it doesn't even stop, the input is supposed to work normally but it just doesn't do anything.

It's either weirder since the animation for the trigger works as usual, but it's meant to cast a laser and there's just nothing.

[dark drum]

Have you added the input action event to an input context mapping that gets added to the player?

[tight moon]

Yes. It worked yesterday morning and hasn't been changed since.

[dark drum]

Does it work in another project?

[tight moon]

Doesn't seem so.

Well, I tried it on an old version of the project, tho same Ue version, but no it wasn't working.

[dark drum]

If it worked previously but no longer is, it could be a driver issue. It might need updating (or rolling, you never know these days lol).

[dark drum]

Looks like a feature to me. 😛 Anyways, it might be best to ask in #metahumans I've not used meta humans myself but issues with hair is a common thing I see with meta humans so it wouldn't surprise me if there's regular discussions there on how to resolve it.

[tight moon]

I'm wondering if it could be something with MetaXR, I used the latest version and since then it broke.

[steady night]

ah aye figured, but someone told me these function cost almost nothing tho

[dark drum]

It's been a while since I've used BT's but I don't believe the 'Is Set' means is true. It just means that a value has been set on the variable. This value can still be false, as in it was set to false but the value was set so the check returns true.

[dark drum]

What they cost depends on the logic that's setup and how many widgets you have with the same binding. It can be very easy to setup logic in the widget variable binding that have a big impact as they run on tick. If it's just checking a variable you'll probably be find but the moment you start doing more complicated checks it can balloon quickly.

[steady night]

yeah i get that mostly these are just checking conditions then someone said it cost next to nothing

[dark drum]

If you're just collapsing the widgets and they never need to be shown again, you could just destroy them instead.

[steady night]

@dark drumyeah thats what i did i was just checking if there was a way to turn the tic of

ff

[maiden heath]

Hi guys, now I have another problem that in the construction of the avatar's eyelashes I see them gray instead of with their material

[tight moon]

So, I tried with another project... and this time it works... I have no idea why...

[steady night]

can i set scrollbox value via BP + / - ??

[wintry imp]

What's everyone's advice on going from world space locations to screen space positions using something other than a player camera?

All the projection nodes take a Player Controller as an input, and I want to identify the 2D position of an object on another camera's clipping plane.

I spent ages trying to do this through trigonometry (calculating the world-space positions of the edges of the camera view, etc) but couldn't get there.

I feel like feeding the object's position into the camera view projection matrix should work and it does give me a location that's somehow relative to the middle of the viewport, but the X coordinate of that position scales with distance from camera to object so it isn't what I'm after.

Should I be pursuing the trig solution, in which case any advice on what I'm doing wrong? Or is there something I need to do with the output of the View Projection that would give me the 2D position I need?

This is me testing out the projection matrix, you can see the X coordinate is relative to the screen space somehow so it kinda feels like I just need to know what that output actually IS and then I can figure out how to scale it to be the 2D value I need.

[tight moon]

WELL PROBLEM SOLVED, IT WAS META XR.

[maiden wadi]

It does cost next to nothing for a mid to high range PC. Low end PCs or older gen consoles it can cripple if you put a couple dozen of those somewhere.

But performance in UI is something that isn't just about making it tick faster. Invalidation and caching is the best way to manage performance in UI. Second best is using less text, and less widgets in general. A Widget's tick and bindings will not run if it is cached, meaning they don't run until the widget is invalidated. So something from outside the widget or an event like a dispatcher the widget binds to, needs to run and set new state to invalidate it so it'll visually update.

And on the bindings themselves, there were some bugs in 4.27 at least where they don't work correctly on some configurations. I had some buttons in the main menu that were supposed to disable. They were not visually disabled, but they were programmatically disabled. The same thing on the widget's Tick worked just fine, calling it's SetEnabled function.

And honestly as a person who works in UI consistently, I personally hate tracking down where logic is running in bindings. I'd rather see a simply tick function than have to dig through multiple bindings and the entire widget hierarchy to see which subwidget the binding is applied to, etc.

[steady night]

thanks for the info i get what your saying

[tight pollen]

Can someone explain to me why this works? Player State is not directly owned by the Client, the Server spawns a copy of PlayerState for clients, but clients do not directly own Player State, so why is RunOnServer called from the client recognized?

(it's in the component attached to Player State)

[maiden wadi]

??? Clients do own their playerstates though.

[tight pollen]

so Would it be okay to call an RPC from the client's PlayerState?

@maiden wadi

[maiden wadi]

Of course. Clients always get the authority to RPC through their Controller, PlayerState, and any currently possessed Pawn.

[tight pollen]

Owning Client

ChatGPT says it's not possible 😄

from Player State

[maiden wadi]

Yeah. The ServerRPC would be dropped if client1 tried to ServerRPC through Client2's PlayerState. But Client2 can send all of the ServerRPCs they want through their own playerstate.

[tight pollen]

ok, thanks 🙂

[maiden wadi]

Generally speaking, I would avoid using GPT to understand concepts. Asking it for C++ code snippets is one thing, and you'll still be correcting it. But it cannot understand concepts. It simply repeats what it interprets people have said online. And people say stupid shit online. Unfortunately there's no easy way around simply testing and understanding it for yourself.

Generally speaking, you have two choices.

1. The child has to pass back this info in a delegate that it's parent can bind to. So the child affects it's struct, calls the delegate and passes that struct back to the parent which overwrites it's own copy of the struct, etc etc.
2. You wrap all of your data in arrays of objects instead. The parent iterates an array of objects and passes those to children. Those children get their internal array of objects and pass then to their children. The objects aren't copied, these are all pointers. So when a child affects it's object's data, it's affected on that object and everything has it updated.

Delegates are added on the child. Event Dispatcher in BP.

Parent binds an event to it's children's dispatcher right after adding it.

[tight pollen]

@maiden wadi what do you think about putting a delegate in Player State that will be called on Begin Play in PlayerState and in OnPostLogin in GameMode it will listen for PlayerState is ready

This seems like a good solution to me, but I'm not sure

maybe I missed something, but then it doesn't need any Delay either

e.g. I keep a register of players logging into the game, but from GameInstance I get the player's name and put it in PlayerState, and in GameMode I have a variable storing all registered players, and these names are obtained from PlayerState

no, it works, Bind On is created separately for each player

unless I didn't understand

[dark drum]

As Scer said, the actor would be bound to the event dispatcher on each of the actors.

[maiden wadi]

The child has an event dispatcher. This is a list of subscribers. The parent asks each of it's children to add it as a subscriber when they bind an event. When child 78 broadcasts, it only runs the event in the parent once, but every other child can still call the event as well.

[pseudo valley]

heyy, i have BP actor for pooling actors with a collider, and i have a BP_Projectile that inherits from that one (Collision is inherited). I take this approach because else the collider wouldnt be the root component and not work. however, for whatever reason, this ALSO doesnt work. anybody know why on component hit for the collision component doesnt fire? Simulation generates hit events is on.

[tight pollen]

so it is good?

😅

Is there anything I should pay attention to?

[dark drum]

The issue you might encounter is being able to bind to the event dispatcher before it's actually called with it being on begin play.

[dark drum]

Make sure hit events are enabled on the collision component.

[tight pollen]

well, the Player Controller comes first, then the Player State, and the Begin Play Event is called when everything is ready

[maiden wadi]

Is this just for the naming thing, or?

[tight pollen]

yes

[pseudo valley]

it's this one right? it neither works if enabled on the parent class, child class nor both For some reason the settings reset the collision settings, i just had to fix those again

[tight pollen]

but it must be 100% correct, because PlayerName is the player's unique ID

[maiden wadi]

Why though?

Why aren't you just using their platform unique ID from the OSS systems?

Relying on names is gonna break. Players rename themselves mid way and 💣

Unique ID's from the OSS they're connected through never change. It's account based.

[tight pollen]

what does this node look like?

[maiden wadi]

Not sure if you can get the unique ID easily in BP. Maybe in 5.

[maiden wadi]

Top I think.

Yeah, the top one. It's a unique identifier for each player's account. Like when you're using Steam as an example, that ID can be resolved to a string that is the same as your Steam ID, the numbered one, not the name.

[tight pollen]

I have never used Unique Net ID. Can I also save these IDs? I mean, will these IDs always be the same for a specific player?

e.g. players play with each other on the local network and the hosting player saves the game, then they want to continue the game the next day

of course, this variable is only for the duration of the game

but in another one I would store only IDs

it seems to me that in this case I should use PlayerName or New Guid

[maiden wadi]

What are you using the ID for? I assumed this was for like property? Assigning things to players?

[tight pollen]

Assigning things, offline/online player registration etc

[maiden wadi]

Right. So I'm playing your game through Steam. My Steam name is Authaer when I Start playing. I play for three days. I change my Steam name to Tarrion. I log in to your game and have to restart.

[tight pollen]

ok, but assuming the game works without any platforms like steam, epic

how does Unique Net ID work then?

just a local game

in 1 house

[maiden wadi]

Every game has an OSS if it's online. Even Null is an OSS, which I'm not 100% on but I think it uses decide IDs for. But in the event that you will 100% never release on a non null OSS, names might be okay. 🤷‍♂️

[tight pollen]

thanks, I'm glad I found you in Unreal Source 😄

in this case I have to modify the system
😬

[steady night]

hmm my inputs dont work in my main menu level (different controller,gamemode,level) do i need to enable enchaned inputs on the other controllers or sometihng ?=

[frosty heron]

well did you bind the inputs?

[steady night]

yeah it works in my player controller but not in my mainmenu controller

[frosty heron]

did you bind the inputs in your main menu controller?

[steady night]

hm no wdym ?

how do i bind it 😛

like the code you mean ?

[frosty heron]

Check your player controller begin play

[steady night]

yeah i dont ahve anything there

did howeveer find that i can ovveride the player input in the controller

but still dont work

[frosty heron]

don't you have this

[steady night]

yeah still dont work

[frosty heron]

show the binding in your main menu controller

and make sure your main menu level actually spawn your main menu controller

[steady night]

it dose

it dose detect OnkeyDown on widgets in main menu level/menu controller

but no input form the inputssystems at all :/

[frosty heron]

#blueprint message
Like here? and where exactly is this?

[steady night]

yeah

in menu controller

[frosty heron]

what's the input mode?

[steady night]

same as where im adding mapping context

[frosty heron]

it has to be game

and not just UI only

[steady night]

oh, input mode :/ ?

i mean i have a game mode and menu game mode

or wdym

[steady night]

ah yeah

[frosty heron]

make sure that's the setting

[steady night]

ah im setting it to ui only

testing

[frosty heron]

that's why 🙂

[steady night]

ahhh

sweet 😛

kinda obvious 😉

thansk

[frosty heron]

👊

[pale obsidian]

saw someone else with this same exact issue. not sure - havent experienced this myself. is this a default MH?

[tight pollen]

is there any way I can convert Get Unique Net ID to string?

[devout badge]

I'm trying to make a timer of sorts, just to test it out
this one only throws a zero and nothing else. Is there something missing??

[thin raptor]

use the built in timer

[devout badge]

built in timer?

[thin raptor]

yes there are built in timer nodes

Also

"get time" only triggers once which is why you are getting a zero

you want get time delta iirc

[frosty heron]

@devout badge Begin play runs when an actor is "alive"

so it run once, most likely at the start of the game if it's a pre-placed actor

If you want to call something every frame, use event tick

Wouldn't make sense to call it start time tho 🤷‍♂️

You can set the start time at begin play
And to see the get time in seconds , print that in event tick

[thin raptor]

ah true

delta time is for animations?

[frosty heron]

depend on the context

delta seconds in tick is the time it takes from previous frame to current frame

[devout badge]

here's what I was trying to do

[frosty heron]

delta just mean the difference

[thin raptor]

use the timer function

timer by function name

then clear the timer when you press whateve

get absolute value of the difference between when you stopped and 5 seconds

or dont actually you want to preserve the sign , nevermind

just check the value of the subtrated result and then use a branch with string append

[frosty heron]

@devout badge you should breakdown your problem, starting from basic functionality.

why don't you try to make a timer for now and just print the result to the screen

You can do this in two ways. One way as mentioned by illuminati is by using the Timer Node.
The other way is adding the delta time where time = time + delta time.

[devout badge]

okay, printing the event function name only prints it once

[frosty heron]

I've stated why, did you read above?

[devout badge]

yeah I saw

[frosty heron]

ok what did I say about begin play?

[devout badge]

its where I set the float

[frosty heron]

read again what I said about when begin play is called

I'm trying to help you but I would just be re-iterating again

[thin raptor]

bro no. You dont set the float in begin play

[frosty heron]

You can set that as the starting time, it make sense

[thin raptor]

yeah set the start time and have another variable in timer that prints the elapsed time

you really want to be using a timer and a function. The timer will loop the function when called until it is cleared

[frosty heron]

[short hinge]

Hello everyone! I'm trying to do some refactor/cleanup in my AnimBPs and found out about Anim Layers Interface. One of the functions in my interface needs some inputs, which I bound to parameters in my main Anim BP (as seen in the screenshot). I confirmed those values are correct in the main anim bp, and I also confirmed the layer is linked correctly (as other animations are working). But for some reason those values from the inputs are not working correctly in the linked layer. Does anyone know what can cause that?

[devout badge]

I got the timer working, now to make it so it actually reads what I'm inputting (like I pressed X on my keyboard for example)
how does one do that?

[thin raptor]

make an input in your game settings

then do Input Action [name action]

[tight moon]

Tough question this time : I have a furniture blueprint, with inside more blueprints for the movable parts. I aim to make a furniture blueprint where you can add as many drawers as you can, but all furnitures themselves are independant from on another. My issue atm is that I can only change the drawrs while in the blueprint, and not in the detail panel. Adding more drawers through the BP is fine, but now I need to modify them while outside of the BP. Is that possible, and if yes how do I do that ?

[tight pollen]

@maiden wadi sorry for the ping, but can Unique Net Id be replicated?
or is it better to just leave it on the server side?

in string variable

[reef totem]

Does anyone know if it is expensive to attempt and fail a bunch of casts? But rarely succeed the cast?

[thin raptor]

define "a bunch"

is it a loop running a hundred times or

[frosty heron]

@reef totem https://intaxwashere.github.io/blueprint-performance/

Go to Myth 3

[reef totem]

It's on overlap. On all of my loot currently. It attempts and fails most of the time, but when a player touches them it succeeds

[thin raptor]

why is it attempting to cast to something other than the player?

[reef totem]

Because replicating with physics is hard

[frosty heron]

that has nothing to do with casting tho

replicating physics is a difficult task even for veterans

not something I would attempt anytime soon

[reef totem]

Basically if the loot touches a wagon that a player Is moving my current system is to set the owner of that loot to the owner of that wagon

So it has different hard references depending on what it is overlapping

Just didn't know if a failed cast is just as expensive as a successful cast

[frosty heron]

casting is almost free

it's the hard ref you need to watch out for

but youtubers likes to make guesses

linked you the article from someone that knows what he is talking about

[reef totem]

Yeah I heard interfaces are technically slower than casts

[frosty heron]

MYTH 4, interface is not a replacement for casting

another youtube bullshit

when you see someone says, use interface, don't cast. Just ignore it

[reef totem]

Appreciate that, just was wondering about failed casts tho. But maybe he doesn't mention them because they don't cost anything?

[reef totem]

Yeah lol

[thin panther]

You still have the hard reference there of that type. Which is the real cost. So yes, that dependency is still made and still just as costly if used improperly.

[thin raptor]

How can I get a bool AND from an Arbitrary number of inputs?

Do I just loop and check if everything is true and set an "all true" variable to true

is there a better way to do that

[thin panther]

Pretty much what you do, and pretty much how those work code side too

The other option would be to loop through, and the first two, then for every other one, and the output with the next one and return early if one is false

Returning early if one is false should be done in any circumstance tho

[thin raptor]

For Each with break then?

[thin panther]

Yup

[thin raptor]

smth like this?

that way I can attach any number of lamps to the door hopefully

Oops I called the wrong open door function dummy

[silent stag]

hey, sphere trace by channel function only collide with first capsule collison i can't hit second one do you know the reason?

[thin raptor]

It works!

[dark drum]

Because the first one most likely blocks the trace.

[dark drum]

This will always call the open lamp door regardless of what happens in the loop body.

[thin raptor]

I know

I tweaked the logic and it works now.

[silent stag]

when the character is in ragdoll mode, it sometimes gets thrown around, but the capsule stays in place. As a solution, I added a trace box to the skeletal mesh to access the character lying on the ground, but it doesn't work as expected. Do you have any other suggestions?

[dark drum]

I would disable gravity/physics on the character and disable collision on the capsule. When you enable ragdoll you might as well forget about the root capsule lol.

[thin raptor]

Excelent. I can add any number of lamps and the door only opens when all of them are on

is there a keyboard shorcut for parenting an object to another object

[tight moon]

Jumping back to this, does anyone have an idea about this situation ?

[dark drum]

You can mark variables as instance editable which allows you to change the vars when placed in the level.

Alternatively, if you make the individual elements as components you could just add the components to an actor already placed in the level.

[tight moon]

Technically, I already have something along the lines of your first line, I can currently change the furniture as I want. The issue I have is that I can't do the same with the drawers themselves. I can click on them, but not change their variables.

Since the drawers are themselves BPs.

[dark drum]

Ahh, you're using child actor components. 🥲

[tight moon]

I had a version that didn't have child components, but then I'd have 4 different components to duplicate at once if I want more drawers. The first solution I came up with was grouping the 4 together... resulting in this.

The drawers are composed of the main mesh, the collision capsule, a grab component and the sphere indicating where the grab component is.

[tight moon]

I think I sense why, but I'm not completely sure why it's so desperate 😅

[dark drum]

The grab component is used in the VR template right?

[maiden wadi]

It should be set on the playerstate of every player, for every player. I think?

[sand bloom]

What do you use to get a mouse click but with a gamepad button? Because for some reason this isn't working

I can't find a good solution online

it's like when you click on ui but with a gamepad vs mouse lol

[kindred galleon]

the binding was the problem, UE binding is bugged. so it was better to just attach to a socket BUT another issue arises where the color is all messed up

[sand bloom]

maybe widgetinteraction isn't the way to go tbf, but this didn't work either lol

I feel like there should be a way to do this and yet

[maiden wadi]

Is this for a 3D Widget Component?

[sand bloom]

oh yeah it is, do you think the issue lies there? It is screen space

[maiden wadi]

That will be why then. The Interaction component only works on the 3D version.

[sand bloom]

ahh interesting. How would I emulate a left mouse click with a controller for anything then 🤔

because click event keys don't seem to work either

[maiden wadi]

Usual case is that you need to focus it. How are you determining what should be clicked in this case?

[sand bloom]

ah I see, so right now I am literally just using it like a mouse

hover over button

click button

Like I literally just wanted to emulate a mouse lol

[maiden wadi]

But hovering what? Like are you moving a widget via the analog stick to simulate a mouse cursor, or center of screen, or using the focus system, or?

[sand bloom]

I am literally moving my mouse with my gamepad thumb stick

which works fine it's just i can't click lol

[maiden wadi]

Ah. Just a sec. I know CommonUI does this but I don't know if their mouse clicking code is BPexposable.

[sand bloom]

👀 oh alright thanks

[glossy cloak]

There's a plug-in for this. Look up virtual cursor I think. It handles everything you're trying to do with a couple nodes to turn it on and off.

[sand bloom]

😭

I was really hoping I wouldn't need a outside solution for something this simple

but i'll keep that in mind thank you if all else fails

[maiden wadi]

The issue is that it isn't so simple. Input is a winding path of madness sometimes.

[sand bloom]

ah yeah fair

for something that should be simple*

haha

[glossy cloak]

Np. I try to avoid plugins when I can as well, but this is one of those situations where I don't think you can simulate a mouse click. And if you can't... That's a lot of work manually coding this for every possible menu and button.

even in unreal there seems to be implications that they wanted to do this but yeah rip who knows how it works internally

Yeah that's true i appreciate the knowledge there is a backup if i really need it

[maiden wadi]

Yeah, you could probably do this with a C++ function library, or a function on the controller maybe. But you might want to go with the plugin he mentioned if you can't do C++.

[sand bloom]

I'll probably do something with the d pad instead if mouse clicks are just impossible

yeahhhh

Here's what I found after a quick Google search. Looking like you're going to be using C++ at the very least doing this yourself.

[maiden wadi]

Yeah. Requires access to the FSlateApplication. Which is pretty much no BP exposure.

[glossy cloak]

This is why plugins exist

[sand bloom]

ah thank you yeah I guess there's just no way to do it, weird. You'd think click event keys would count(like i have no clue what they would count for lol). Maybe just anything but 3d widgets. I'm probably just going to try a dpad solution instead

I don't mind plugins for certain things but idk

[glossy cloak]

I can vouch for the virtual cursor plugin though. I use it in my commercial project.

[sand bloom]

I'll definitely keep it in mind 🙏

[maiden wadi]

I extended CommonUI's CommonAnalogCursor for Red Solstice 2. 😄 I was surprised how easy that was to make a gamepad analog cursor out of it.

We also do hovers for like scrolling areas. If you hover a Common Scrollbox with the analog cursor, the cursor shows arrows so that you know the right stick can scroll the boxes. It worked out pretty good I think. We also still allow DPad to snap to buttons like normal cardinal nav, so that users aren't forced to use the analog cursor if they hate it.

[sand bloom]

ohh that's cool stuff

that sounds nice yeah, i've heard a lot of good things about commonui i think

Giving the players the choice is a nice detail

[maiden wadi]

This was custom stuff we wrote in, but their CommonAnalogCursor made it really easy to put in with some C++. And I strongly recommend CommonUI for any project, but even more for anything using gamepads.

[sand bloom]

ahh I see

[tight moon]

Just back home so I don't have it all in front of me. The grab component is in the drawer blueprint, it's the component that allows the grab action to actually grab anything. It's not used in the furniture blueprint directly.

[silent stag]

Can i ragdoll in place? i tweak some mesh physics settings but it does not work

[copper chasm]

I was so excited I found a plugin on github to search data table row by gameplay tag, but alas, it is slightly out of date and rider throws about 500 errors

wait hang on it was literally missing one include

[tight pollen]

how can I load all saves from Saved folder

I have Save slot1, save slot 2, save slot 3 ..... and I want get all saves and load all

do I need to create another save that stores all these saves?

is there a better way from blueprints

[maiden wadi]

Usually people just make the RowName of the Datatable the GameplayTag. There's a ToName function for Tags so easy to look up.

[iron idol]

what is this trying to tell me? Its from my saved system. I have it set up exactly like my weapon save which works fine

[maiden wadi]

Try this.

[true valve]

How can I convert player location and use arrow texture on a 1080x1080 map texture? Trying to create a world map system

[iron idol]

i'm really confused. to my eye everything looks right

[tight pollen]

I don't have Find Files

it is plugin?

[maiden wadi]

Oh, need to enable it. I don't remember the plugin name. It's from the engine though. Blueprint... File.. Utilities or something?

[maiden wadi]

Can you delete the nodes and replace them?

[iron idol]

i can try but refreshing does nothing

deleting and redoing does nothing

is this a bug? I'm so confuesed

its saying something about an array but its not an array...

lol it randomly just stopped

i did absolutely nothing. i just hit compile like 6 times

[dim halo]

Thank you. For some reason I thought for bools “is set” correlated to true

[copper chasm]

Sure, I’ve set up a number of ways to get the name myself, but I’ll be darned if just using the tag straight to look things up won’t be handy

[maiden wadi]

But it's just literally this at that point.

[copper chasm]

Then you’re naming rows blah.blah.blah and if you typo something you’re borked - you can convert the tag down to a chunk, but then you’re running extra code

If the tag is already in the data table, you don’t have to worry about the name of the row (you still should, but)

[maiden wadi]

You also have to iterate every row to tag compare.

[copper chasm]

I mean, it’s doing that with the FNames

[maiden wadi]

It's not. It's a map.

A Datatable is just a fancy wrapper for a TMap<FName, FSomeDataStruct>. Maps don't iterate rows when finding the correct entry.

[copper chasm]

I can’t imagine it’s THAT bad on performance though?

[remote meteor]

lookups on map and set are literally o(1) tho

[cyan scroll]

how do i make projectiles spawn in random range? like random recoil

[thin raptor]

multiply by a random value

[cyan scroll]

thx

[thin raptor]

probably want to split that struct pin

depending on what you want to do, but I suspect you only want randomness on 2 axis not all 3

[cyan scroll]

yes, i already done it

[thin raptor]

k

[cyan scroll]

thank you for the idea

[narrow pendant]

does anyone have some good talks / blogs on planning out project architecture, big picture best practices etc?

[nova scarab]

Is there any way to show 0 graphics like in a dedicated server?

[steady night]

when i play in PIE everything works with my Gamepad but when i build the game gamepad dosent work at all

[narrow pendant]

are you using enhanced input or the debug inputs?

[steady night]

enhanced

dosent work in standalone game at all either

im using the same inputs for keyboard those works

just nothing related to gamepad inputs

[past hull]

hello,
I am trying to refactor my fire weapon logic. Before I was using an interface CanFire and now I juste want to call a function "Fire" on my weapon wich is inherited by my SMG, Pistol etc...
But I cant turn my existing code into a function because of the timeline and the play montage. How can I tackle this issue ?

the timeline is for the recoil pattern

so I used a custom event instead of a function but i am not sure if its good coding practice

[trim matrix]

as long as its tidy i dont see any problem

you could also split the code into smaller chunks of functions and events too

[cyan scroll]

so if im doing a game where player shoots projectiles all the time, should i use object pool for projectiles?

[maiden wadi]

🤷‍♂️ Maybe not. Could work just fine in most games. But it feels like an odd thing to do to avoid typos. I'm not personally a fan of datatables much anymore. I use data assets for most things.

[broken wadi]

I wouldn't bother unless you notice it impacting performance. It kinda depends on the complexity of the projectile actor and the frequency they are being spawned and how long they stay alive for. You could easily stress test this by setting up a few spawners and crank up the firing rates to see how well it performs.

[pallid oxide]

Trying to create a weapon from a database that has an ID but this isn't working probably because I'm new to UE, Is there a better way to do this?

The idea is to place an empty actor with a static mesh, type in the exposed ID variable to get the correct ID

[dapper forge]

ello. why this always return 0?

context: trying to make something generate based on "random" seed. and seed being jsut host machine name(string)

answer : ue is poo. do this manually instead

(apparently)

[iron idol]

guys, just how many functions in a bp is too many functions

[maiden wadi]

Need more context. Are you not seeing the print? If no, then if you put another print after the Datatable row getter, do you see that one? Is this blueprint's beginplay running at all?

[maiden wadi]

There's no real definitive answer to that question. What is your context of "Too much"? Like performance? Organization?

[iron idol]

perfromance

is having like 50 functions in a BP very heavy?

[pallid oxide]

Thanks for responding, The print doesn't return after datatable row getter either so I assume it's not even running

[maiden wadi]

Non answerable question then. You could have five million and not have it cost much. The functions in question, how they're called, how often they're ran, what they're used for. Too much context.

[maiden wadi]

Is the Beginplay running? I'd assume so if it's just in the level. Your name is valid. Is the Datatable set?

[iron idol]

they are only ever called one at a time. The code within them is short

[pallid oxide]

A print after beginplay works

I'm not quite sure whats wrong, the datatable is set because a randomized version of this script works

Except it iterates through an array and selects between the other 5 from the data table

This is the only part that's different in the Random one

[maiden wadi]

There's also target platforms, what class the code is in( there are usually more pawns than controllers for example). Many things running simple code can cost more than one thing running complex code.

Older gen consoles really die on collision queries and overlap code, and movement code calls. A mid level PC won't notice these things.

So in general the only correct answer is "It depends™️". You can't really do much more than profile it with Insights.

[maiden wadi]

Is the datatable pointer set? Cause I can't see any other reason your Row would fail to find.

[pallid oxide]

Still new to blueprints, do you mean the difference between the options under variable?

edit : nvm the Set is clearly different because of the size

Mine is a Get

[frosty heron]

In UE4 at least if you bloated your blueprint too much, I get all sorts of nasty artefact.

At the moment I can only work for 15 mins before I have to restart UE

My blueprint stops displaying anything when I right click

[maiden wadi]

This

[pallid oxide]

Both are the exact same and point to the same table

Random script works flawlessly still

[maiden wadi]

Oh

I missed that before.

Change this to 1

[pallid oxide]

works perfectly fine now, is this because it's getting the internal integer ID from the .cvs?

[maiden wadi]

The Ro here is your RowID column that the GetDatatableRow is asking for.

[pallid oxide]

I thought I'd need to make my own ID of itm_001

If that's the case then I'll have to remove the id tab lol, thanks I have been pulling my hair out over this

[maiden wadi]

If you want to keep the itm_001 stuff, just change the RowName to that.

[pallid oxide]

I can't change the rowname at all can I? I read it was a bug with UE 5.0+

[maiden wadi]

O.o

[pallid oxide]

It automatically adds itself even if my spreadsheet doesn't have it

If I rename the first row, the spreadsheet breaks (Becomes unreadable)

[maiden wadi]

Cause the first row on the spreadsheet is the row name.

[devout tide]

You can always write a custom export function but that would require CPP or python

[maiden wadi]

You can change the rowname by clicking on it here if you want to change it in editor.

If you export it as is. You'll get a normal CSV.

[pallid oxide]

now this is extremely helpful thank you

gonna export and work on it like that instead

👍

[maiden wadi]

Rename the first column and reimport it.

[warped juniper]

Just got a weird but where the player heals back all damage dealt to them

I changed nothing of health recently

[maiden wadi]

Hackers 🤷‍♂️

[faint pasture]

gotta see that code

[warped juniper]

https://blueprintue.com/blueprint/a8-9szm4/

[pallid oxide]

Removing the row with the exported CSV keeps the old row before "Row Name" when re-imported, so I'm guessing I'll be forced to just delete the beginning row in unreal editor every time?
