blueprint

[fallen glade]

God didn't make me smart enough for C++ so that's a hard pass haha

print this

if they are characters with AI etc you can't if they're just meshes you can spawn them and remove them from within a single blueprint

[sage pecan]

It keep printing the Name of the Main Character Blueprint

I tried in Enemy Blueprint as well, it print the Main Character Blueprint as well

[gentle urchin]

I should've never gone there...

[pliant violet]

Hi there - cautious question: I have some aiming logic for a top down twin stick shooter, and so I set two axis for "forward" and "right", but it seems to be working fine looking all around by just plugging in the aim forward event. Does anyone see something wrong with this?

[atomic salmon]

@pliant violet your code is driven by the AimForward axis event but it doesn't use the Axis Value from the event, it retrieves the values directly for both axis and combines them with an Atan2 function.

In that sense you are using your AimForward axis event a bit like an On Tick event, taking advantage of the fact that, as an axis event, it fires continuously

[pliant violet]

Okay, so either Input event (any movement of the analog on the gamepad) will trigger the values to the SetRelativeFunction node?

I was surprised it works if I move the analog stick to the right, for example. I was trying to avoid tick for times when the stick isn't moved.

[atomic salmon]

InputAxis events fire continuously, even when the the controls are in the center

If you debug your BP you will see it

[atomic salmon]

it works because the AimForward events runs continuously and, inside it, you retrieve the value from the AimRight axis event and use it. Whenever you move the stick to the right that value is updated.

[trim matrix]

Guys i need help. I am quite nrw to unreal engine and trying to make my first game. I have a fps widget and i want to hide/show it by pressing a button in my pause menu. I've got it working by pressing a keyboard button but not a button in another widget. Please help

[pliant violet]

Thanks so much for all the insight! Do you see anything wrong with that, at least for prototyping purposes?

[atomic salmon]

@pliant violet logically it is a bit weird because you are using an axis event to trigger an action which requires the value of another axis, but it is not the worst piece of BP code I have seen. And since it works it is ok for prototyping.

[pliant violet]

Once again, thanks for the insight

[manic wigeon]

hi guys, i have an issue atm that the widget is not being removed when the player leaves collision box. i have put in the code but not sure if something is missing.

[dawn gazelle]

Are you just trying to detect when a player enters the attack range collider of the enemy?

[serene fulcrum]

This is all I use to move my character, I disabled all use controller rotation options on the character and the use controller desired rotation on the character movement component. Moving forwards and left/right handles about how I'd expect, but for some reason going back will allways end up with the character being aligned with the world forward vector (walking backwards alongside it that is). Any idea what may be causing this?

[civic briar]

Are you also trying to print out the enemies name ?

[atomic salmon]

@manic wigeon you need to learn to debug your BP's by using Print Strings in combination with the visual debugger and breakpoints. The first question is: is the trigger event firing when you leave the box? If yes, is the code to remove the widget being called?

[sage pecan]

Yupp

[atomic salmon]

@manic wigeon Add some Print String at each stage so you know that part of the code is actually being called. Eventually you are going to find where the problem is.

[dawn gazelle]

So the overlap event you've shown is within your enemy blueprint right?

[chilly lodge]

How would I add a neav mesh to a bp, for instance passengers, AI Boarding a train ?

[civic briar]

It's printing the main character because that's where it looks like your overlapp is setup. @sage pecan

[dull meteor]

Thank you. I may just have to gather some knowledge on these systems from what is currently available and build around that.

[serene fulcrum]

Using GetActorRightVector / GetActorForwardVector has the same issue

[civic briar]

If you want to print out the enemies name, you need to refer directly to the (other actor) and get info from there

[sage pecan]

But the AttkRange event is in the Character Blueprint now
So should I transfer it to the Pawn as their hitbox rather than the character attack range?

https://www.youtube.com/watch?v=JNUik-YLWUc&t=180s

This is the tutorial I'm following but is unable to make it work

[serene fulcrum]

An illustration of what happens when moving backwards

[dawn gazelle]

Well which is it you're trying to do? Detect when the player is within the enemy attack range, or detect when the enemy is within the player's attack range?

On the player, all you should need to do is connect "Other Actor" from the event into your cast and it'll probably work for you.

[sage pecan]

From the tutorial, it seem to achieve the latter

[dawn gazelle]

On the enemy, you should be able to do a compare between "Other Actor" and "Get Player Pawn" or "Get Player Character" and if true, then you know the actor that's overlapping is indeed the player. But if you want to do something to the player on the enemy blueprint, then you may want to just cast the "other actor" to "Juggernaut"

[lofty hound]

Can anyone tell me when using Maps in blueprints, when i get the keys and values and output them to separate arrays, do they maintain the same index as they were in the Map?

[worthy frost]

yes

[tight pumice]

hey, whenever i use get all actors of all on edit/standalone i get the same order, but when i get all actors on build, the order is different, but every build kinda the same, whats the order, pls help

i men whats the algorithm order for this specific function

[zealous moth]

@tight pumice iirc as they get instanced they are cached in that order.
If you want a specific order then make a map and create them in the desired order

[runic parrot]

Hi! is there an already made way to serialize a struct into a string and than back from string into struct?

i can make my own function, but if there's something already made i would like to make use of it.

[red grail]

How can I add a timeframe to this condition? I want the transition to only happen if the movement speed is below 10 for 0.2 sec for example.

[worthy tendon]

Do this check in animation blueprint. then mark a bool as true and use that bool directly in this enter transition check.

[red grail]

in here?

[worthy tendon]

yes

something like this

I would collapse these nodes to make it look cleaner

[red grail]

I'm playing around with it, need some time to wrap my head around this lmao

[red grail]

This kinda works I think, but I feel like it might be stupid to do it like this. Thoughts?

[lyric holly]

I cannot figure out where the circled Target/Root Component is coming from in the blueprint. Isn't root component the scene root? When I drag that out I don't get something that says "Target" on the left

[faint pasture]

Is there a dirt easy way to debug print a struct or do i gotta break this thing and concantenate a string together?

[worthy tendon]

dont use delay. use game time

[tropic pecan]

Hey there. Once, again, does anyone have an idea on creating a "Set Game Paused" blueprint to pause and un-pause with different keys such as like "P" for pause while having "b" for un-pause while requiring to be back at the main pause menu before closing to the game play? I've search for tutorials from YouTube and Unreal Engine learning but they are all the same. They all keep setting it up to the same key which is not what I'm looking for. Please does anybody have at least an idea of that case?

[drowsy ridge]

Hi all,
I'm dealing with this very weird bug!
I'm currently working on a small hack and slash game. For the hit detection, I created a blueprint anim notify state which is fired in the animation montage, within that state I tell UE4 to fire a spheretrace. For some reason it's not appearing in the anim montage, but it is in the actual game. It used to show in the montage, but somehow it isn't right now!
Here's how it's set up in the anim notify state:
https://blueprintue.com/blueprint/zl3q_oe7/

[drowsy ridge]

I figured it out nevermind!!

[gentle urchin]

Not that i can find or is aware of, but it would be helpfull in some cases (altho my structs usually has to much data for it to be usefull in a single print)
You could make a custom function for it, but still need to tailor it to the specific struct ..

[red grail]

Yeah, would have been my guess as well after seeing yours. Thankfully I found a much simpler way that doesn't require me to mess with the animation bp. Thanks for the help tho!

[tropic pecan]

I thank you for the advice but I'm afraid it's more complicated than that. I have structured my open pause menu in this structure for separating game mode and pause mode. I am trying to create a related JRPG Function.

[faint pasture]

Make the whole system state driven

[tropic pecan]

How do I exactly do that, may I ask?

[faint pasture]

Use an Enum for your states. In my case, it's the HUDUI state

so when you press a button, you pick a new state based on current state then update stuff

[tropic pecan]

I need to take time analyzing this then, thank you very much for some advice. Could I text later about all this or should I not?

[faint pasture]

Sure that's fine.

[tropic pecan]

Alright, thank you.

[faint pasture]

Are you guys getting a 2s delay on PIE?

It's like theres a 2s wait before game starts up, never noticed that before

[lusty wave]

Is there a reliable way of telling in a construction script whether the game is running or whether it was called because of a change in the editor? In other words I want to separate [PIE, Standalone Play, packaged game] from spawning or editing an actor in the editor.

[faint pasture]

Figured it out, this project used to have some garbage code plugin and its GameInstance was still being used and had a 2s load time lmao.

[gentle urchin]

Wouldnt beginplay be what you wanna use when its not ment to happen in editor ?

[lusty wave]

I'm trying to do the opposite - run something only in the editor

[gentle urchin]

Got an example of what?

Usually thats what i use on construct for

Or you can make a custom event and make it callable from the editor (button shows up)

[lusty wave]

@gentle urchin In my construction script, I'm moving an object to a specific position. The inputs I need to compute that position are available in the editor, but not at runtime. If I understand correctly, I should just be able to set the position in the editor and that will be saved in the map and I shouldn't need to set it again at runtime.

[gentle urchin]

The actor will keep whatever position you gave it when placed in the map, yes?

[lusty wave]

You mean the parent actor of the object I am moving? Yes that is correct, it is static (as is the child component that I move in the construction script)

I may have figured out a straightforward way: Make a C++ function that checks EWorldType on the world instance and makes sure it isn't EWorldType::Game. I don't see an existing blueprint function for this but it's easy enough to add one.

[gentle urchin]

Damn, well played. 😅 Alot of functionality is not exposed to blueprints sadly

[lusty wave]

@gentle urchin Actually it doesn't work, but I think this is because I misunderstood something more fundamental. I thought the changes from the construction script were persistent, but that doesn't seem to be the case. The position I set in editor doesn't get loaded at runtime the way I thought.

[gentle urchin]

What? How so? They're changed as if in editor, so why wouldnt they persist

[lusty wave]

If I run SetWorldTransform in my construction script BP (both in editor and in game) it works. But if I only run it in editor, the transform snaps back to Identity (0, 0, 0) when I run the game standalone.

[gentle urchin]

That sounds very odd

Pretty sure i've successfully used construction script in editor, and it persisted in packaged game. (Swapping meshes etc)

[lusty wave]

Yea, my expectation was that this was one of the best use cases for the construction script.

[lyric holly]

the construction script is like a constructor in c++?

is that the idea

[dire frost]

yep pretty much

[lyric holly]

can you do all of that in the event graph?

just curious

[hybrid ether]

Why these settings are not saving?

[dire frost]

like in begin play instead of construction? sure but you wont be able to see what the constructions script's doing in the viewport

[dire frost]

you should save the post processing variable or it will go back to default - 1 when you open up the UI

or just dont apply the settings when you construct the options menu

but it's the best to assign the post processing quality to an int and save that into a game save slot

just a quality of life thing. so the players wont need to reset the setting everytime they boot up your game

[hybrid ether]

I thought Apply settings saves those to config:0 but okay I will try that! @dire frost

[dire frost]

yeah that's true but you need to load those settings using "Load setting" node

this video should help you a lot here @hybrid ether
https://youtu.be/ehDxu1goiSQ

[hybrid ether]

Thank you!

[lusty wave]

@gentle urchin Finally found something that seems to work. I was trying to set the Transform on a light, but it didn't seem to get saved at all. Instead I made a new instance editable variable on my blueprint actor and wrote the transform there. When the construction script ran at play/runtime, I applied that saved transform to the light via SetWorldTransform. Still feels like I'm missing something or have failed to understand how the construction script is supposed to work

[bleak merlin]

Is there a way to do a hitscan/raycast to a umg widget? Trying to find a way to create a reticle and have it be accurate for a third person game.
Think I found solution working on it now.
Nice works great!

[hushed pewter]

The forward vector works correctly

But I really aint sure why this shit

Is keeping me stuck

I can only move regular forwards and backwards, and its not getting modified based on the camera

[bleak merlin]

what are you trying to do?

[hushed pewter]

Just move based on cameras position

Just getting the forward vector, then moving in that direction

I was origionally using get forward vector from rotation

BUt I went too the premade first person blueprint

And copied it point for point

And it still dosent work

[faint pasture]

So what you have

[hushed pewter]

Just move in direction the camera is facing

Regular first person movement

[faint pasture]

Show your blueprint nodes between the input and when you add movement input to the character movement component

[faint pasture]

That will break down when you're looking up or down. Think about it, you're telling the character movement component that you want to move in the cameras forward direction. Will that forward direction is pointed down, you will get less relative movement.

[hushed pewter]

Even so

I tried braeking it apart

[faint pasture]

Assuming your capsule is inheriting control rotation, try using the Ford and right direction vectors of your capsule

[hushed pewter]

THe issue is im stuck moving in +X -X +Y and -Y with no effect from the forward vector

[faint pasture]

Print the output of the get forward vector on camera, does it change when you turn?

[hushed pewter]

Only camera rotates

[faint pasture]

Whoa, what is going on there. What are you trying to do with all that?

[hushed pewter]

Y just lets me look up and down at restricted angles

X is just standard

Same as in first person template

This was all working fine before

But after adding my particles it suddenly stopped

So idk if I accidently disconnected something

[hushed pewter]

Alright, it was updating too fast

So I just seperated the values

Thank fucking christ

STupid engine

Haha

YEEEEEES

Taken a few days

BUt blar blar

[jade nova]

Ok

So

How can I make something like arcade driving physics

I searched all YouTube and can’t find any stuff

[pliant violet]

Hi there, my spring arm goes haywire when I enable collision on my player pawn. I made sure to set the Spring arm to have Absolute rotation, but once this "ball" hits the ground, the camera rolls forward and to the side.

Am I missing something?

Right before contact

right after

[prisma path]

How do I generate a list of random actors? It's like a shopping list, each actor/item has an item type in enum variables and each element of the list would be from different item types.
Would I have to create an array variable for each item type and then get one element from it with a random int? The problem with this is I might have hundreds of items

[fierce birch]

anyone know how to reference a material instance parameter through bp?

[pliant violet]

This may be the answer here: https://gamedev.stackexchange.com/questions/182709/how-can-i-expose-material-parameters-in-the-unreal-level-editor

[fierce birch]

@pliant violet any way to do it form an actor?

[pliant violet]

Hmmm depends on what you mean. What is an example?

[fierce birch]

basically i want to pick up a coin and it will materialize over time and disappear

i have the instance applied and just want to change a value on the instance over time

[pliant violet]

If the coin can be made a Blueprint, there are variables you can expose as a parameter using "Instance Editable".

You could have that be the time it takes to disappear, for example. For the material to be referenced specifically, I am not sure. Sounds feasible

@fierce birch

[fierce birch]

ok. because i have parameters in the material instance that i want to access. but i appreciate you taking time to try to help me

[prime bone]

I have a minimap widget that I wish to disapear when I am moving left (pressing a). is there anyway I can do this?

[fierce birch]

@pliant violet got it

set the scalar parameter value

is the function

@prime bone set the visibility

to hidden

or remove from parent

[prime bone]

how do i set the visibility?

thats what ive been trying to do

oh its jsut a node

omg

[last pond]

hey all. I keep getting this error when my Line trace doesn't register that it hit anything. is this something i should worry about or is it just telling me it hit nothing?

[forest sable]

Hello guys, I have been trying to store a widget withing a save game then recall it a gain but that seems to not work does anyone know where i can find the type of vars I'm able to store is a save game and what i can not, thanks ❤️

[last abyss]

its saying you hit nothing, but still are checking if that nothing is simulating physics.. you could just hook the branch before it up with the return value of the linetrace node

[analog maple]

Hi, has anyone else had any issues with binding a progress bar to health? I've tried doing so, but it seems like it stops querying at some point.

[last pond]

Ahhhh ok thanks 🙂

[fierce birch]

@prime bone yes

its a node

[forest sable]

Anyone ?!

[tight schooner]

@forest sable I think a widget is a spawned thing and it's pointless to save a reference to something spawned within a save game because it's necessarily destroyed between sessions. You have to save the data that the widget uses

[forest sable]

that's what i did i had to save the vars within the widget and then reconstruct it upon launch with that data

[dawn gazelle]

You can't save object references in a save game at all.
If you show a bit of your saving / loading code then we all might be able to advise a bit more beyond this.

[jagged kelp]

Hi all, is it possible to get the forward vector of a non-character bp?

I have a moving ball set as a physics actor but can only get it to return 1,0,0 as its forward vector in a print while traveling in a loop

all the tutorials I have found for it have used characters so I figured it was time to ask the question

[gentle urchin]

Cant you add an arrow component for that?

[jagged kelp]

I will give that a go right now

[spark steppe]

arrow components dont exist on packed game

you may want to get the velocity and normalize it

[gentle urchin]

^ Didn't know this part

Not sure if velocity is correct either, since you can have velocity in a not-forward direction

I'd think blending by slot is easier

[jagged kelp]

yeah that would of been a big oof, I will give the velocity a go

[gentle urchin]

Yes exactly

https://docs.unrealengine.com/4.27/en-US/AnimatingObjects/SkeletalMeshAnimation/AnimHowTo/AdditiveAnimations/

..by bone* is the node

[unreal plaza]

What (S) mean?

[spark steppe]

scalar

[unreal plaza]

Thank you

[mint acorn]

Hey All

Why is my mouse not showing in my level??

The widget gets created but I have no mouse to interact with it??

[spark steppe]

you may have to set a mouse cursor

[mint acorn]

Hey Ben

I do Set Show Mouse Cursor ??

[spark steppe]

yea, but you probably don't have any cursor style assigned

[mint acorn]

ok i'll look into that - thanks

[gentle urchin]

If we'd only have the left part, then it would additively blend pose and blend pose 0. Blend pose 0 would only have something to blend if you were playing a montage. The setting on the blend per bone would specify which bone to start from, and how "deep" it should go

[hoary orchid]

How to cast to BlueprintUtilityWidget?

[gentle urchin]

I would think so yes (been a while since i played with anims)

Hmm ...

root motions aren't ment to be blended, are they

So root motion must be part of a full body blend

weight of 1 would mean full override (no blending)

per bone yes

With the blend pose 0 being a root motion montage, set to full body ?

I'd imagine something like this

currently in the ALS project, so i havnt come around to add new slots or my own overlays etc yet, so ignore the naming

but i'd think the root motion montage would be part of the "BaseLayer" slot here

It's been a while tho, so i could definitely be wrong

did the anim state stuff work out btw?

[forest sable]

Hello guys, I've been trying to rotate an object in screen space and i have had no luck with that, been looking on the internet for a while but i couldn't find what i needed

[gentle urchin]

Maybe more luck asking in #animation , probably someone with a bit more control than me 😛

[gentle urchin]

rotate in screen space?

[forest sable]

yes

[gentle urchin]

Not sure what that means exactly

example?

[forest sable]

https://i.imgur.com/LSELPwn.gif @gentle urchin

[gentle urchin]

During runtime?

[forest sable]

yes

just like graphics program do

[gentle urchin]

with a sphere for axis selection ?

[forest sable]

no the selecetion would be direct on the object

[gentle urchin]

Most of it can probably be achieved with a widget, reacting to mouse enter, button down and sending translation to the object in focus

[forest sable]

but the rotaion would have the same behavior yes

[midnight kiln]

Do you mean mean in game or in the editor?

[forest sable]

in game

[forest sable]

I have don the part of selecting the item i just can't get the part of the rotation right

[gentle urchin]

while mousebutton down -> add mouse XY axis to rotation of the actor

[forest sable]

well that is what i have now but that rotates the object in world rotation

so it doesn't behave as if it was following the mouse

[gentle urchin]

it should

probably at some weird rate , but it still should

keep in mind mouse movement is only 2 axis, so you might need some magic to make it work nicely in 3d space

[clear solar]

Hey guys. So I just started using unreal and I wanted to recreate a game I made in unity. Basically the game has only two rooms and by entering one and for example inside a trigger if you press a button there are changes on the other room. New paintings on the walls or even new object like a radio that when you enter the trigger it starts to play music. The way I did it was bu enabling or disabling the game objects. What should I do to recreate this in unreal?

I obviously don't want the full answer step by step

Just need something to point me to the right direction

[eternal reef]

Starting off simple you could just play a trigger box in the world and on overlap fire the event where you set the objects either hidden in game, change visibility (dont forget to remove collision) or you could also just move them by hitting that event
All of this stuff could be done in the level blueprint, but you could also create a blueprint actor for the objects and prepare the logic in there which gets fired by the level trigger box to go more for a "modular" way

If they all are the same class you could use the "get all actors of class" and manipulate them within a loop without having to specify each single one

But Id place both of them in the room and depending on the choice either one becomes visible, so you dont have to worry about the placement of the objects with vectors if you have to move them back in

[odd veldt]

What is a better way to optimize a NPC Character.
Changing Tick Speed, using a Timer or using a other way?
I already using the "Was Recently Rendered" but I need a running event to update the NPCs. if they are visible.

[spark steppe]

that depends on what you want to update and how frequent it should happen

[dire frost]

yeah it really depends on how accurate or in other words how fast you want your npc to react to new information

and also you make a global information pool. so instead of every npc the player's location for example, it's an actor or whatever you want that has that info and every npc access it when needed

[clear solar]

Very detailed answer thank you. I don't understand everything just yet but I'll do my best.

[unreal plaza]

How to limit first person camera Yaw roatation base on level?

[surreal peak]

There is a Make Rot From X or so node

[worthy tendon]

vectors don't have roll. so RotationFromXVector always gives 0 roll.
Make Rotation from Axes might have roll which can be defined by right or up vector. I don't know why there are 3 inputs. with 2 vectors perpendecular to each other you can determine Pitch Roll and Yaw.

[honest wolf]

You can use the PlayerCameraManager (https://docs.unrealengine.com/4.26/en-US/API/Runtime/Engine/Camera/APlayerCameraManager/) and call LimitViewYaw using either the Level Blueprint or you could create a DataTable containing level name and the limits you want to apply and parse that when your Actor spawns.

[atomic salmon]

@swift pewter the names of those functions are a bit misleading imho, but you should read X, Y, Z as Forward, Right and Up. MakeRotFromX assumes you are using a forward vector. MakeRotFromXY uses a Forward and a Right vector, the Z (Up) vector will be calculated internally using a cross product.

MakeRotationFromAxes uses all the axes as input, enforcing orthogonality between each pair.

Also the documentation for those functions is misleading, it talks about rotation matrix but the output is actually a Rotator (you can transform one to the other, but still)

They work as expected once you understand what they do

But their names/documentation may deserve some TLC

@swift pewterThe CMC already has a function to orient rotation to movement. Is this what you are after?

@swift pewter check that the input vector has length > 0 before deriving any rotator from it

start by using a Print String to show what the input vector looks like at each frame

once you have seen that, you can devise a solution to the problem

If it is easier, you can also visualize a direction vector using DrawDebugLine or DrawDebugArrow

In this way you can see where the vector points

Yes, you can add them to your debugging toolbox. Very handy.

[unreal token]

Please, point me in the direction, how do i make a super nice menu with a movie behind it or the game behind it, you know how some games you click start and the menu buttons disappear and it's the start of the game.

[atomic salmon]

@unreal tokenhttps://www.youtube.com/results?search_query=ue4+game+opening+menu

[unreal token]

yeah they're all super basic stuff

and some don't work anymore

[atomic salmon]

@unreal token if you are learning you need to start from something basic, then improve it. There are some recent ones, so I assume they work. Don't pick one older than 2-3 years.

[unreal token]

yeah i did like 5

actually more because the ones that were obsolete i stopped doing

i'll ... well i don't know

do something else, sorry

thanks for trying to help. i appreciate you even answering

[atomic salmon]

@unreal token if you give it a try and then come back for specific problems/issues it may be easier to help you out. Also a better channel to ask about menus/widgets is #umg

[unreal token]

oh ok thank you @atomic salmon

[atomic salmon]

@swift pewter I saw you already had an extensive discussion about that. Did you follow already some of the recommendations that were given to you?

@swift pewter if you need to switch between two states, working with a bool is the way to go

if you foresee that in the future you may need more states, you can think of a different solution

but in general you want to adopt the minimal solution which covers your use case

[arctic moat]

Hi, Im having a bit of problems with the way the Player tag (above the head) interacts with the world. When a player is behind a wall, you can see the player tag through the walls which i don't want

i have the player tag set to "Screen" in the space

[atomic salmon]

@swift pewter it's not because I say it, it is because it works. So if something works and doesn't cause side effects (or regressions), it is assumed to be ok.

[arctic moat]

I don't want to change it to "World" since it looks a bit horrible.

[manic wigeon]

When player goes in the collision box widet pops up. but when player is not next to it the widget is still on the screen

guys can anyone help me identify why this error is popping up

[atomic salmon]

@manic wigeon how are you handling the End Overlap event? That is, when the player leaves the trigger volume / collision box?

[arctic moat]

.

[brazen pike]

Ay is there any way easy way to mass enable a post process material on a lot of items (like every interactable item) while also not enabling any other post process material? I have three but I only ever want one enabled at a time. Do I need to cast to every single item I have on the map and enable post process materials (while changing the blend weight for the other two) every time I press my key (a black and white mode which is toggle bound to 'Q')?

That solution feels extremely inefficient and can't be the only solution, right?

It feels wrong that only one post process material can be enabled at a time. So is there any way to deal with that?

[earnest tangle]

It seems you should be able to have them enabled all the time, but instead parametrize their effect

Then you could use a material parameter collection to adjust when the effect is enabled or not

[unreal plaza]

@honest wolf Thank you! That's exactly what I needed. I saw the first method on a project, but when I trying to use it I found out it doesn't work when you want set specific limits to different level.

[honest wolf]

You probably wanna make use of Custom Depth. http://www.tomlooman.com/the-many-uses-of-custom-depth-in-unreal-4/

[atomic salmon]

@arctic moat you could also do a visibility check from the widget to the player camera using a line trace, hiding the widget if the test fails

[arctic moat]

i've come up with this solution where when the player is close to the other player (2500 units) the tag displays and the rotation is always facing the player

this solution works, however...

it throws out all these errors. Is this because of event tick?

[spiral gull]

Hey folks,
I am using tags in my game and just discovered that there is a thing called "gameplay tags".
They seem pretty useful especially because of the hierarchical structure but for the love of me I can't figure out hot to assign a gameplay tag to an actor.
I am sure it is crazy simple but I guess I just can't seem to get it.
Can anybody help me ?

[gentle urchin]

Isnt there a gameplay tag component one must use

i think you can give the ActionRPG example from Epic a look

[dawn gazelle]

You can just create a variable on the actor of type "Gameplay Tag Container", and then create yourself an interface to retrieve the tags of the actor.

[spiral gull]

@dawn gazelle oh, I see! Thank you 🙂

[dawn gazelle]

Probably - if your character hasn't spawned yet tick may be trying to pull the Get Player Character before it exists. An IsValid check would likely alleviate your issue.

[arctic moat]

perfect. IsValid? works and fixes the error

[brazen pike]

So I should enable them using "Render Custom Depth Pass" (on the BP's mesh) at the start? I have one of my materials a highlight which enables render materials on that mesh when the player is looking at it... If I have it always enabled, would I not need to then edit the values of the material itself rather than the individual mesh to enable my highlight material, causing every item to highlight when I'm looking at any item?

Currently set to highlight on event tick when player looks at it

and to enable render custom depth pass

Because I DO have one enabled at all times, but I want it to be applied to only the mesh I'm looking at, so only the mesh I'm looking at can receive it, while its sending it to them all

[brazen pike]

If I had them all enabled, and tried to use a parameter collection to enable it, surely all my meshes would light up at once

But my goal is to have a button which lights up everything at once (using a different material) and when that button isn't pressed, only one is lit up (what I'm looking at)

[chilly jetty]

Hi everyone, I have a slight problem. I have a post process material that lets me see actors that has RENDER CUSTOMDEPTH PASS enabled through walls. I want to change the color of the Post Process mat but only for the actor that is being hit with a sphere trace

I'm not sure how to access the Mat instance in BP and how to make the post process material be individualistic for each actor

[brazen pike]

I swear either post process materials is one of the more confusing things in ue, or one of the less developed sections

[chilly jetty]

might be both haha

[trim matrix]

is there any way i can add blur to a background image in, for instance, a main menu?

[brazen pike]

If you mean a widget, you might be looking for a 'background blur' which you can rearrange in the hierarchy to ensure only one part is blurred

[trim matrix]

oh i got it thanks

[dapper forum]

Guys, how do I "force release" all keys upon game pause?

My game has some mechanics as for example holding RMB to target an enemy. But if I pause the game while that button is pressed, when the game is unpaused, the functionality gets stuck, which is specially bad with special powers that charges while holding down keys.

I've tried clearing variables, but the button release behavior still happens

[dire frost]

you can make a custom event called "game paused" or something which pretty much does the button released script and you would call that event before you pause the game

[pliant violet]

Hey folks, I want a top down shooter where my player pawn has collision enabled, but I don't want any "jump" of any kind. Will constraints on the x,y,z rotation and z axis position be enough for the player pawn?

[dapper forum]

I kind of tried that, that's what I mean when I tried to set all variables to their original state (e.g "special attack == false")

But when the game is unpaused, the button release event still happens cause it was never actually released

[dire frost]

oh you want the release event NOT to happens when you pause right?

[dapper forum]

exactly!

not even after the game is unpaused

as if it was never pressed in the first place

[dire frost]

you can make a bool called "is paused" that gets true when you press the pause button. so when pause and the release event is trigger it wont carry on with the script because the bool is true and after you unpause obviously you want to set the "is paused" bool to false so when you actually release the button it works properly

i think that should work

[dapper forum]

got it, that actually might work! thanks a lot

unfortunately it didn't work. I think I really need a way to flush out all held keys from memory when the game is paused

there has to be a way

get player controller -> unbind all events from on released - doesn't work either 😕

[dire frost]

can you make a delay for setting the "is pauseed" when you unpause>

do that while i think of a solution lol

make it a short delay

oh! and can you check if the button is pressed?

[dapper forum]

I've also tried that! even with long delays =/

[dire frost]

try checking if the button's pressed

you should get that from the player's controller

[dapper forum]

ok, let me see

[dapper forum]

@dire frost I was thinking backwards which caused me to think the problem was in the release when it was actually on the pressed event. Thanks for pointing me in the right direction, the solution was pretty simple:

[dire frost]

lol at least you fixed the problem now!

[dapper forum]

yep, just need to replicate the solution in all my hold down events lol

[pliant violet]

hey crew, how can I get my pawn to spawn closer to the ground? If I adjust my PlayerStart I get the bad size error

My root component is just a static mesh

[dapper forum]

Check your character_bp, the mesh is probably too high in the viewport

[jaunty solstice]

I have a public variable of type 'Texture' in a regular, not Material, Blueprint.
How do I scale this texture?
If it were a Material Blueprint I would simply use a TextureCoordinate node but this doesn't exist in regular Blueprints.

[pliant violet]

Should I replace the static mesh for a different component for the root?

Can't adjust the static mesh height since it is the root

[dapper forum]

Yeah, you don't need to replace the mesh, just adjust its height on the Z axis:

[pliant violet]

Since I am using a pawn, I think I am unable to change the height. Unless I am missing something?

[dapper forum]

I'm sorry, I don't quite understand what you did there. Doesn't matter if it's a pawn, I can add a static mesh to it and I'll be able to edit its location:

Maybe I'm the on that's missing something 😅

[pliant violet]

No no it's okay 🙂 I appreciate the help. I replaced the root component (in your scene, the DefaultRootComponent) so now I can't adjust the transform.

I can do two things in my head - use a different root component, or mess with the player start

[dapper forum]

OH RIGHT, got it now. You can't indeed edit the scene root's height, that's why we usually add the mesh component separately. I've never tried your way to be honest..

[pliant violet]

All good 🙂 I am going to just apply gravity for now! And keep the mesh as the root component. I see my options now and this will work for prototyping.

Sometimes you just need to talk it out with someone. Thank you!

[tight schooner]

@jaunty solstice I'm not entirely sure what you mean. Materials can have parameters (float, vector, etc), and in BP you can create a dynamic material instance and then set those parameters on the fly. That's the general workflow for BP affecting materials

It's up to your material graph to use the parameter inputs in some way, like to multiply texture coordinates. BP can't do that directly.

[dire frost]

on construction script cast a line down to get the ground location, get component bounds of your mesh and get box extent/2 and add the Z axis to the ground Z axis so the pawn wont spawn in the ground

note you need the pawn to be above the ground

[pliant violet]

Thank you!!

[dire frost]

your welcome! and you can make some other checks in cases like if the pawn was placed under ground or stuff like that but it will be more challenging

[trim matrix]

Anyone experienced a bug that open level node works fine in editor but in standalone and in packaged it doesn’t work?

I have put the map in the packaged settings to include it

Maybe should I delete saved files?

[dire frost]

do you mean like the level does not open?

[trim matrix]

I have a main menu map, when the button pressed it opens loadtransition map, and from there I open the game map with open level as soon as all assets are loaded

But it doesn’t open game map

In editor works as expected

I read that and others had the same problem and they deleted saved folder and the problem fixed

I will try that

[karmic sonnet]

see how helpful this group it, I posted a question and then figured it out immediately 😄

[trim matrix]

im trying to cast to my main_Pawn Character but for whatever reason it does not exist even with context sensitive off only other thing with main in the name is the anim bp and im not about to delete my character

[silk inlet]

Hi guys, I'm trying to re-create the navigation system for a mobile game. The reason is that I want some customisation later on. Right now I'm still learning the basics.

The right button is set to jump which I have set up. The left button is supposed to work like the default input which moves the inner circle left and right. How do I make it happen?

[worthy tendon]

open your Main_Pawn. maybe it's not loaded. sometimes it happens

[trim matrix]

did that several times i even restarted my engine and still nothing

i might honestly have to go to the BPI Route and pass a refrence through there im on 4.26.2 btw

[worthy tendon]

get the cast to Main_Pawn outside animation blueprint, if that appears. then copy paste

[trim matrix]

ill try that

[trim matrix]

ok thank you that seemed to work thats so werid though why it would not lemme cast directly

[worthy tendon]

yeah, No Idea either. sometimes It gets anoyying

[spice valley]

Is there any way to set default values for saved values?

for example a saved bool I want to be set to "true" when a player first plays the game

I tried just setting it in the savegame itself and it worked in editor but not builds for anyone who tested it

so I had to do a system where it checks if you've launched before and if not manually sets the defaults, but that's very cumbersome and means future updates can't set defaults either

[earnest tangle]

In my game I just set defaults on my variables, and tick the savegame box. When a game is loaded, it just overrides the defaults on the variables

I'm using EasyMultiSave but you could do it like that yourself too I guess

[last walrus]

1. you can set the default value of variable
   2)if you want this default value tu be set more than once - make one more variable with same value and give it's value to needed variable

[trim matrix]

how to disable the tick in the widget blueprint ?

[last walrus]

you can just dont use it
until you connect it to any function it does nothing

[hardy fable]

the content browser will show you the ticking state of a widget if you hover over it

[glossy bane]

Is it possible to rotate individual instanced meshes that have been created trough a construction script? When I try it using a simple timeline, lerp rotator and set world rotation nodes, the instanced meshes have very unexpected behaviour, like vibrating in a single spot, while all im trying to do is rotate them passively arround their own axis

[gentle urchin]

Its possible yes , but with construction script not to my knowledge

[glossy bane]

well I am creating the actual rotation in the event graph as usual, by using a reference to the instanced mesh, it just seems to be rotating it arround the axis of the entire blueprint actor instead of around its own axis

[civic briar]

Can you not just use add actor relative rotation node ?

[gentle urchin]

Its not an actor , but an instance of one

[peak crater]

Can anyone think of a reason that a variable set to a user widget class would resolve to None on runtime even with a default value?

I'm not clearing it

[gentle urchin]

But updating their rotation one by one shouls be pretty straight forward at runtime i think

[glossy bane]

I'm just not sure what is happening at all. Like referencing the instanced mesh from the construction script works as I do see movement on the particular instances that should be moving, but its literally vibrating in place instead of doing any actual rotating

I have an asteroid field and I just want to make every single asteroid rotate passively arround its own axis

[peak crater]

Wow im dumb

nevermind

[gentle urchin]

Vibrating at runtime?

If so, please show some code

[glossy bane]

yes, it starts when I run the project

[civic briar]

Also to change the variable for multiple instances, instance editable needs to be enabled

And if you are spawning the actor in BP, are you storing the instance in a variable ?

[gentle urchin]

Instance editable doesnt need to be on, but the spawned iinstanced must be handled. Show some could would help :)

[glossy bane]

I dont spawn the actor Ive just placed it manually in the world

[hardy merlin]

I have a transform problem. Given a forward vector Start and forward vector End, how can I generate N additional vectors that are evenly rotated between Start and End?

[glossy bane]

this is how im trying to rotate it atleast

[civic briar]

You just trying to make it spin around on the Zed ?

[gentle urchin]

This is not per instance (you're using ism right, or did i just assume to much?)

[glossy bane]

Yeah I just want to have an asteroid field and then every asteroid to be slowly turning/rotating arround its own axis like its floating in space

[glossy bane]

what does ism stand for?

[civic briar]

Why not just straight off event tick of the actors BP, use add relative rotation node and input values manually to test

[gentle urchin]

Ism = instanced static mesh

Being an astroid field, anything else sound very costly (except particles)

[glossy bane]

that just makes literally the entire field start to vibrate uncotrollable, the same way as it does when I do the code in the solution, only there it happens for the actual referenced asteroids

[glossy bane]

yeah they are instanced static meshes trough the construction script

[civic briar]

Ohh yeah sorry I've been misunderstanding you this entire time

[gentle urchin]

Show me that part aswell

[hardy merlin]

I think I can use the Ease node on rotator

[gentle urchin]

Just so we're 100% on the same page

If urbusing the ism component, you must use the ism set instance transform nodes aswell

[gentle urchin]

Perfect

So you need to loop through the instances, and update their transforms o a per instance basis

Theres a special node for it

[glossy bane]

Do I do this directly in the construction script?

[gentle urchin]

No, you gotta do it at runtime

[glossy bane]

Could you give some hints how I would go about this, and what that node is called? I'm still new to unreal and just recently started looking into instanced meshes

[gentle urchin]

2 sec , omw to the pc :p

[glossy bane]

thanks!

[gentle urchin]

Once per frame (or once per change, whatever comes first) you must mark the render state dirty

So usually at the end of the update loop

[glossy bane]

ok yeah Ive never seen this before, so it takes in an array of transforms

[gentle urchin]

ill see if i can dig up an example

i made some silly space scanner many moons ago

which used isms

[glossy bane]

I see, I'm not exactly sure how to handle the new instances transforms array

[gentle urchin]

For starters its probably easier to use the Update Instance transform, and just do them one by one

I see my example project isnt very good for explaining or making an example of either really

Basically, some method to find the amount of insances ( i assume you wanna rotate all of them, so get instance count should work for you)

then looping through that , updating the transform of every single one

[glossy bane]

so essentially something like this?

can't see any change when I did that atleast

[gentle urchin]

No, because thats only one instance

you need more like this

wether you do it in a timeline or on tick or whatever is mostly the same stuff

you can also add some randomization to it so they don't look 100% synchronous

[glossy bane]

will try this asap, was just wondering about the bools on the node, should I not use mark render state dirty and use world space instead?

[gentle urchin]

you only wanna set render state dirty once per frame , as i've understood it

[glossy bane]

understood, yeah it's a very confusing node I'll keep working to try and make it work, thanks alot for the help

[gentle urchin]

the setup i showed you should work, with a static +1 rotation in X direction

i'd set it to event tick just for testing, and see how it works 🙂

[glossy bane]

right, where would you put the combine rotators in my case with a timeline? this is what im trying right now and cant seem to get a result

[gentle urchin]

ignore the lerp part

but in the timeline aswell complicates it , and sort of doesnt make much sense since you want them to constantly rotate

so tick is easier

[glossy bane]

yeah true I got rid of it and they started rotating (albeit very laggy)!

so I guess I just go for this solution instead of the batch node

thanks alot for the help

[gentle urchin]

How many instances?

[glossy bane]

scratch that I just had to bump down the tick rate and they became much smoother

[gentle urchin]

I bet its cheaper to do batch updating aswell

[glossy bane]

yeah I was about to ask how this is performance wise considering there may be a large number of instances

[gentle urchin]

ism's dont like post 100k

1k seem fine

[glossy bane]

got it, thanks!

[gentle urchin]

framerate is clearly taking a hit already at 5k

[glossy bane]

yeah I'll have much fewer, probably in the range for 300-500

[gentle urchin]

that should help alot

if you use low vert meshes aswell it seem to help quite a bit (sorta obvious i suppose)

[glossy bane]

yeah my stuff is pretty basic so it will probably be fine performance wise

[glossy bane]

thats alot of rocks :p

[gentle urchin]

500 😛

the bp

[hardy merlin]

Confirmed. the Rotator Ease function does precisely what I want.

[glossy bane]

Oh so you get your transforms and instances count directly from the construction script

[gentle urchin]

i define them from my variables really

[glossy bane]

Im just not completely seeing where you actually create and append your transforms array with all the instances transforms, and also im not sure what the node "set array elem" is at the end

oh it just clicked, thats where you append the array

[gentle urchin]

The array is resized in construction script

Final revision of it

3 editable variables, Instances, Radius and Spreadangle

spreadangle is up and down, while the circular is evenly spread in this sample

[glossy bane]

wow alright yeah I can kinda see how it's all connected, will start chipping away at it

[gentle urchin]

sort of expected it to be a nudge cheaper to access an internal array of transforms instead of the ISM's array, but seem to be equal

[glossy bane]

are you referring to the batch update vs straight up update node differences?

[gentle urchin]

No i was thinking about the for loop in the tick event,

where i sort of blindly expected it to be quicker to "get element at this array index" vs "get instanced transform"

[glossy bane]

right I see it now

[glossy glade]

I’m trying to give character abilities a certain Status effect associated with them from a Bitmask enum called Status. So I set them with a literal enum value. I later have a bitwise '&' check for groups of Statuses (like ones that prevent movement or ability usage).
The bitwise check always fails because the int bitmask variable contains wrong values
Each int bitmask variable (eg. MovementImpairingStatuses) will have several relevant flags set on.
When referencing a literal case of the enum it gives an int value from 0 to N. When referencing an int variable set to be a bitmask for Status it gives unexpected results. Any idea what’s going on?
Shouldn’t this work?

A more narrow question is: shouldn't I be able to do this:

Status B = Status.Stunned;
Bool C = A & B.IntValue != 0;

If (C) {
     Character->DisallowMovement();
}```

[earnest tangle]

iirc it should be possible to use bitmasks in that fashion yes, but I never learned the math for it so I tend to just use some other methods because it's just simpler to deal with :P

Your screenshots aren't really doing any bitwise comparisons as far as I can tell so hard to say what's happening

[glossy glade]

The screenshots just show that I'm creating what should be the same values in different ways and they print out as different values

If I create an Int bitmask variable with "Stunned" set on

Then an Enum literal with "Stunned" selected

They should have the same Int value

[earnest tangle]

Ah, a literal enum isn't a bitmask, what you're doing is you're just converting it into its numeric representation. I don't think a bitmask value will directly match the uint8 representation of the enum

I don't know what types/values are in the TEST variables though

[glossy glade]

I thought that was the point of checking the Bitmask box at the bottom of the Enum file

[earnest tangle]

I think that just enables its use as bitmask values

https://www.fatalerrors.org/a/introduction-and-use-of-bitmask-in-ue4.html have you looked at this or anything else on google?

[glossy glade]

I'm familiar with bitwise operations (in other languages) with raw enum values

[earnest tangle]

well it should work the same way in BP's

since it's really just a layer on top of C++

[glossy glade]

I have done some googling on this and apparently it was actually a bug in Unreal, but was ostensibly fixed a while ago

So I'm trying to figure what step of the process I'm doing wrong

[earnest tangle]

Well have you tried just doing regular bitmask operations on the values? Do those work?

[glossy glade]

Namely, how do I get the bitmask value from an enum literal

Yea, just doing the operations on two int variables works

[earnest tangle]

Looks like Make BitMask is the node used in the guide I linked

I'm assuming if you connect it into the appropriate pin it'll show the enum's values instead of the default selections

[fierce birch]

hello all. I have a materialize function that i custom set the amount to through a timeline. the thing is that the change to the material affects all that have it. is there a way that i can only make this change to the one instance?

[earnest tangle]

Use a material parameter instead of a material parameter collection, then you can adjust it directly on a specific instance of it

[glossy glade]

That works for setting them explicitly, but not for the bitmask ints

[earnest tangle]

Hm, not sure then. I'm sure there's some guide you could find on google on this, doesn't seem like such an unusual thing to do

[glossy glade]

I've done a lot of googling and haven't found something talking about this issue specifically. But I'll keep looking

It honestly seems like a bug though. I have bitmask int variables TEST_Stunned flag set to "Stunned" and TEST_Slowed set to "Slowed" (for example) and both print a value of 0

Whatever the proper way to format bitwise operations - that doesn't seem right

[velvet dagger]

Need help, trying to make something activate when a node is true or false, is there a node for that? Can't find it online :/

Please @ me if you respond :)

[earnest tangle]

Branch @velvet dagger ?

[glossy glade]

This actually does appear to be a bug in UE5 at least. It seems to be related to changing the source Enum file after creating variables that reference it

Creating new and identical bitmask int variables behaves normally

[velvet dagger]

🤦‍♂️

[earnest tangle]

Ah, yeah that's why they say don't use UE5 unless you are ready to edit the engine source to fix things lol

[velvet dagger]

imnew :')

[earnest tangle]

Yeah I recall I tried to search for "if" and it didn't show up, which is a bit of a weird gotcha

back when I was new

[velvet dagger]

Hehe

[tidal pier]

I'm having an issue. The line trace is working as it should, coming out the end of the gun, but ending on where the crosshair is. But the Niagara emitter start point isn't following the end of the gun rotationally. Like it points at the right spot on the wall, but its like the start point isn't properly rotating with the end of the gun so its offset. Any ideas?

[velvet dagger]

Ok so ik it's random and jumbled but that's only because I'm testing stuff, so what I'm trying to do here is make it where when the timer is up and you press right click, it'll activate something. I bet this isn't even the right way to convert exec's to and's. And the timer gives a short pulse instead of being constantly on once it's completed, anyway to fix that too?

Been at this for a w h i l e

Please @

[obtuse herald]

Nodes with execute inputs need to be connected with an execute output from another node to work

Your set node on the right is not connected, thus it wont fire

Also you're always setting 'Qwe' to false, you probably want a get node

[tight schooner]

@tidal pier make sure the Niagara modules handling those locations are operating in world space, or whatever you need it to be. Whenever locations aren't happening correctly in my Niagara systems, I tend to look at local/world space issues first. IIRC, a lot of Niagara modules are localspace by default

[obtuse herald]

I would recommend you to watch/read a tutorial to get a grasp of the very basics. After that have a look at 'Gate' nodes, they're probably thar what you're looking for.

[fierce birch]

@earnest tangle my apologies but could you elaborate further?

are you talking about this?

[tidal pier]

So looked into that but it seemed to be set to world space. However, I'm wondering if I didn't have something saved cause I had closed it down before checking it out, and now its just working? lol

[fierce birch]

@earnest tangle i got it

i looked a video by matthew up on it

thankyou

Good to hear :)

HOLY crap

I'm just very bad at Booleans

Sorryyy

[winter kettle]

my "find in blueprints" tab isn't working, it just says "Searching"

[velvet dagger]

This is killing me, I'm trying to get health from an actor I gave health too. When I drag from the object thing there's no node called like "get actor" and everything else I choose just gives me errors. Am I just really dumb?

It's a blueprint mesh thing

Supposed to have health

[rugged wigeon]

Your image shows you casting "nothing" to a Garden_Live, and returning its health.

which doesn't make much sense. You'll need to describe more clearly what you intend to do here.

@velvet dagger

[velvet dagger]

I'm sooo sorry

It's late

I'm trying to make a health widget

[rugged wigeon]

And you want a reference to the actor whose health is supposed to be tracking

[velvet dagger]

Yesyesyes

Is it even possible with actors imsodumb

[rugged wigeon]

On your widget, add a variable. Make it the class of the actor who will own it.

On the variable options check off "Expose on Spawn". This will add this parameter to the "Create Widget" node.

So go back to where you're creating this widget, and add the actor whose health it is. If that's done within the actor's own blueprint, you should get a reference to self and pass that.

Lastly in this function you've screen shotted, just get that variable, and pull the health out. Forget the casting because you've already made sure the variable is he correct class.

[velvet dagger]

How make it the class? ;/

[rugged wigeon]

Variable Type Dropdown

For now you can consider "variable type" equivalent to "class"

From your picture I'm guessing its called Garden_Live

[velvet dagger]

What do I select in it? 😥

I'm sorryyy

[rugged wigeon]

probably garden live?

whatever your actor class is named

How can I add and remove edge loops to a procedural mesh? The mesh to work with is all quads

[light token]

Hello people. I have a blueprint with a lot of child components which are static meshes. Now when I try to cast the component to StaticMeshComponent I get cast failed. How do I get the static mesh from the child component?

[maiden wadi]

@light token Show the hierarchy of the blueprint you mentioned.

[trim matrix]

Im not an expert but since the array is already of static mesh type, i dont think you need to cast to static mesh component, could you try removing the cast node and attaching the exe and reference pins to the rigid body collision node directly?

[light token]

@maiden wadi

@trim matrix Then I can't set the rigid body hit events method.

[maiden wadi]

Those aren't StaticMeshComponents, those are ChildActorComponents.

[light token]

Yes

But they contain cylinders

I need to set hit events enabled on those cylinders

[maiden wadi]

Cast the GetChildrenComponents array to ChildActorComponent, GetChildActor on the ChildActorComponent, and then possibly cast that to your actor type to get the Cylinder and set it.

[light token]

Alright awesome man!! Going to try that out right away!

@maiden wadi I get a Cast Failed on casting it to ChildActorComponent

I'm doing it like this right now

https://blueprintue.com/blueprint/q-b8gq5o/

[maiden wadi]

It may be the IncludeAllDescendants check. Probably don't need that on since they're all direct descendants of the scene component.

[light token]

That was it!

[maiden wadi]

That may be returning the root component of all of the actors as well if they're attached the same way, which wouldn't be child actor components, so the cast would fail on them. Technically what you have there would work, but it would have casts failed if thats the case.

[light token]

I wish I could thank you more than this. I was struggling with it for hours

Thanks again!

lol

[maiden wadi]

Haha. Child actors are a particular kind of hell.

Don't care for that component.

[light token]

I converted the static meshes to a blueprint. The engine did that by itself

[deep hound]

wondering if someone has a slicker way to changing float to text, but with conditions. What I mean by that is if a number is less than say 10, show 1 decimal place, otherwise, show no decimals

this is what i'm currently using

i can easily do a branch or something, but didn't know if there's a cleaner way i'm not aware of

[last abyss]

you can use a select node

[gentle urchin]

Or round to int, convert to string, measure number of chars in string (integrals) and switch on that

cleaner? Not so sure

[hardy fable]

huh, TIL, the override selection thingy that the post process struct does isn't a custom thing, but just what happens if you put EditConditions on struct properties . . .

Does anyone know how to take high res screens in a loop

I have 43eshes and would like to take for each one a screenshot

It's written in a for each loop giving an array of meshes

But putting a delay or anything else doesn't work it takes the screenshot but only of the last mesh

[eternal reef]

Maybe instead of a for loop you could just use some variable which you increase each time for the index in the array and just make it a "custom" loop with a delay

[ocean oxide]

Does anybody know what the logic for when OnConstruction/Construction Script is called during cooking? I'm trying to get some objects to snap to the ground and I'm doing the raycast from the Construction Script to avoid content creators having to poke things manually after geometry gets updated.

Weirdly enough, my logs from cooking are implying that it's being called twice for a lot of actors, often hitting the ground the first time and then missing the second time. I'm a tad confused and nobody else here seems to quite know how they work.
The main problem though, is that 90% are just missing 100% of the time, but that could be all kinds of factors if I don't know exactly when it gets called. Is the entire level it's in spawned?

[obsidian pelican]

@eternal reef tried that :) but also no effect:/ it like the loop is faster and when the take high res is triggered it takes to long to make the screenshot

[obtuse herald]

Are you using the same filename for every screenshot?

[obsidian pelican]

Nope it takes the name of the mesh as filename
Basically : loop start -> set name based on mesh -> set mesh in viewport -> do some lighting stuff -> take the screenshot. -> next index

I also implemented a counter to see how many times it goes through the loop and the loop works as it goes 43 times

Can we do a async loop?

[obtuse herald]

Yeah, not in bp (without plugins) tho

Try the loop index as your filename

[obsidian pelican]

So it should save the screen with the counter as filename ?

[obtuse herald]

Yes

[hardy fable]

you make an async loop macro if you make a copy of the default for loop and stick a delay in there

[obtuse herald]

That's not async tho

[hardy fable]

It'd still work tho if his issue is all the screenshots going off in one frame

[obsidian pelican]

I'll try both methods later hope this works :)

[ivory shadow]

What's the difference between the two nodes?

[pseudo pelican]

Hey guys, im kinda new to everything here. How would I make this bind more generalized so I can use the same bind on different text blocks and get different colours for each without duplicating that colour index value a million times?

[gentle urchin]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Spline/GetLocationatTime/ vs https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Spline/GetLocationatDistanceAlongSpline/

In many ways they are the same

just with two different inputs, time vs distance

[primal smelt]

I assume blueprints is the correct channel for materials related questions? I'm using world displacement on a material and I have just noticed that it doesn't seem to play nice when rotating the mesh it is applied to. So for example if I have a subdivided plane used as a wall facing one direction, the displacement map is adhered to correctly. But if I rotated it 180 degrees to face the opposite direction, suddenly the displacement map is inverted (so cracks in the wall are now protruding). Am I supposed to be getting the normal of the surface and somehow plugging that into my displacement multiplyer in the materials editor? If so, how do I do that?

Also bonus question: Is world displacement the same as parallax mapping? Or is the latter calculated per pixel instead of per vertex?

[ivory shadow]

Makes sense, that's what I thought

Thanks!

[trim matrix]

Hi, I have question, which may be easier for more experienced devs: how do I make a projectile that has a bigger collision for enemies than teammates? There a catch: both teammates and enemies use the same preset: pawn

[eternal reef]

Maybe add an additional damage collision to the projectile which uses a special object channel which only enemies react to

[worthy tendon]

tooltips are good explanation. Time is basically between 0 and 1 where 0 is start and 1 is end. Distance is actual distance along spline in cm

[worthy tendon]

I guess you can ask in #graphics

[clear solar]

I made this blueprint that when the player enters the trigger and presses right click a sound is played but it doesn't work. Any ideas?

I have to tick the little box?

I did but it didn't work

[dark crow]

Cause it plays sound at location 0 0 0

You may not hear it

[clear solar]

still nothing

[worthy tendon]

you need to swap events. when overlap happens, set a bool to true, when overlap stops set a bool to false.

when right click happens, check if that bool is true and play sound

hint: you need ActorEndOverlap as well

[clear solar]

like this?

[worthy tendon]

Yes, remove the RightClick bool variable

you dont need that

and simply connect Right Mouse Button to the branch

[regal venture]

On Entered: CanPlaySound= True
OnRightClick: branch(CanPlaySound) -> Play Sound

[clear solar]

Wow it worked

thanks

that's officially my first blueprint xD

[worthy tendon]

this is wrong tho

[regal venture]

You're not done yet.

[clear solar]

yeah I fixed it like you said

[regal venture]

Now select multiple nodes and hit the Q key

[clear solar]

oh ok

[dark crow]

You can use GetActorLocation for Location

So you don't hardcode the number

[regal venture]

Or use PlaySound2D, if it's not supposed to be at a location

[clear solar]

PlaySound2D is for ui right?

[dark crow]

That works too if doesn't need to be localized

[regal venture]

Anything that doesn't need to be spatialized

[clear solar]

oh ok

[regal venture]

UI, music, ambience, some dialogue

It just won't be emitting from an in-world location. It'll always be audible in both ears

[clear solar]

I see

[dark crow]

Stereo love

[clear solar]

yeah I did

thanks though

[pseudo pelican]

montage pause, montage resume

[ivory shadow]

Guys how can i do this: If a variable is True [Play Animation] Else [Play another animation]

I have done it but it doesn't working

I've done this

But its not working

I send now a video

Thats it

[dark crow]

You're not resetting the do once

[manic wigeon]

guys can anyone help me with assigning a set of cinematics to a widget button? when i click on preview i want to play a level sequence to display the object.

can anyone help me?

ye thats why im asking for help

its not letting get reference to the cutscene in any method im trying

only in level bp it lets me reference to the selected cutscene

this is in level bp but when im in a widget bp it doesnt show up

so can you help me?

anyone?

[dire frost]

you can try "get actor of class" to get the refrence to the sequence player

[manic wigeon]

but i cant see the cutscene as reference in the class

[dire frost]

maybe try casting it to the specific sequence player? am sure there's a better way to do it but i cant think of any

[manic wigeon]

in the screenshot you can see i tried using level sequence player but at the end its asking for a target self to reference to either the character or the sequence

i found the cutscene in the sequence player its just the end were i need to refernce the target seems to be a bit strange

[dire frost]

yeah this is confusing lol. sorry i cant help out here

[manic wigeon]

anyone else can help me on the issue by any chance? surprisingly no one has done a tutorial on this. if someone helps me figure this out il do a tutorial on it

[velvet token]

Is that what you want to do?

[worthy tendon]

this can go wrong in many ways

[worthy tendon]

just connect "ReturnValue" of "CreateLevelSequencePlayer" to "Target" of the "Play" node. execution pins (white color) are connected correctly in this picture

[manic wigeon]

yes like that

thank you

i figure it out before. i was like tripping of why i cant get ref of sequence.

but thank you for showing interest

[worthy tendon]

just becareful if you ever happen to have more than one level sequence actors, then things may break.

[manic wigeon]

so if i have 3 different scenematics how will you recommend it to be best

maybe through a branch?

[worthy tendon]

you dont need GetActorOfClass node

CreateLevelSequencePlayer already gives you the player

[manic wigeon]

ok cool thanks

[obtuse herald]

I don't know if I missed it but what exactly is your problem?

[manic wigeon]

can someone help me with an issue?

[velvet token]

Just post your issue and with a bit of luck someone can help 🙂

[manic wigeon]

im trying to pause my scenemtic but its not working

if im understanding my nodes. im saying that when i press space i want to pause the sequence player by refering the sequence player which is currently running its its on bp

[velvet token]

Does your InputAction actually fire?

[manic wigeon]

its not using this print string

its not saying hello during scenematic and i press enter

which is suppost to pause it

[dark crow]

You have it in the Sequence, you sure that receives input?

[obtuse herald]

Set that to Player 0 in your actors details panel

[manic wigeon]

it worked with enter before to skip a scenematic so i think so ye

[manic wigeon]

in the edit blueprint of the master sequence?

[obtuse herald]

yes

[manic wigeon]

not seing it

[velvet token]

click on "Class Defaults"

[obtuse herald]

That are the propeties of the input node

[dark crow]

Press X to doubt

[manic wigeon]

cant find the setting for input

[manic wigeon]

.

[manic wigeon]

.

im already ing defeaukts

[velvet token]

oh sorry I just saw that you already did that

[obtuse herald]

it's usally somewhere near the bottom

scroll down

[velvet token]

Probably the level sequence actor doesn't support that?!

[obtuse herald]

Level sequence actor is an actor, and actors support that

so it should be supported

[velvet token]

Just created one myself, it's not there

[manic wigeon]

im trying to figure out why print string is not showing me during scenematic why space to pause my scene is not working

[velvet token]

Anyway, the "cleaner" way would be to create your InputActions in the player controller or character class

[obtuse herald]

yepp

[velvet token]

It's not printing because the onject you're trying it in doesn't receive any inputs.

Do you have a player controller already?

[manic wigeon]

its not letting me refernce the pause for the scnematic from the fps character

oh wait is it this one?

[manic wigeon]

.

[velvet token]

No

Oh you mean the InputAction?

[manic wigeon]

trying to pause on action

[velvet token]

yes

[manic wigeon]

shall i do a branch to do a press again for resume

?

[velvet token]

Really depends on what you want. There's also a node called "FlipFlop"

[manic wigeon]

yep good call

is it resume or continue

to call it to continue

[manic wigeon]

.

[velvet token]

for the sequence player? I think you just call Stop to stop or Play to play

[manic wigeon]

sorted

i think this works right?

[velvet token]

But that pauses your whole game, is that what you want?

[manic wigeon]

the game will be showing the scenematic

because its previewing the scene of the model thats showing

couldnt find a specific player for scenemtics in character bp

[velvet token]

I mean you can try, just saying that this node will pause the whole game, not just the level sequence

[manic wigeon]

i mean it paused but for some reason its not continueing

i need to redo this

ugh

[velvet token]

quite sure you only want to pause the level sequence for this reason

[manic wigeon]

ye i do but i dont see an option

shall i try this?

[velvet token]

You need the reference to the level sequence again, just like before in your very first question

[velvet token]

yes

[manic wigeon]

so how will i redo this to defin if paused insteadf

[velvet token]

maybe I don't quite understand what you are trying to achieve. Could you describe your intentions a bit more clearly?

[manic wigeon]

its not getting self to pause

so what i want is to pause on space

and be able to press space again to return to the scenematic

[obtuse herald]

that

no

ain't working like that

[velvet token]

no?

[obtuse herald]

you're creating a new Level Sequence and telling the new one to stop

the old one won't care what the new one is doing

[manic wigeon]

ye its doing that

it restarts the cinematic

everytime i press space

[obtuse herald]

wait it does work?

[manic wigeon]

no

it restarts cinematic when i press space

i need it to pause

and then continue on second time

i press

[obtuse herald]

ok

[velvet token]

my mistake, you're right 😄

well do it on begin play

[manic wigeon]

why did you create a variable?

[obtuse herald]

that would work

[manic wigeon]

trying to learn

why does creating a variable make it work?

[velvet token]

to save the same sequence player, otherwise you create a new sequence player everytime

[obtuse herald]

exactly

[manic wigeon]

so the variable allows for the function to happen to anything after the variable is applied which would mean the sequencer is then ignored to restart?

[velvet token]

with the method before, you would just create a new sequence player, tell it to start, then the next time you create a completly different sequence player and call that on to stop. Those were not the same

[manic wigeon]

aaa ok

[velvet token]

If you only create it once and save the reference you "speak" to the same sequence player everytime

[manic wigeon]

and the variable what is it? vector 2d orr? why is it blue

[velvet token]

Right click on the "Return Value" and "Promote to Variable"

it will create a variable of the correct type for you

[obtuse herald]

it is a 'Level Sequence Player Object Reference'. (just drag the bottom node of 'Create Level Sequence' and select 'Promote to Variable')

[manic wigeon]

something is still wrong

still restarting

[eternal reef]

Use a validated get before the creation with the variable and if not valid create it, otherwise skip to flipflop

[manic wigeon]

i need someone to visually show me what he said haha

[velvet token]

I think that was my mistake in the screenshot, you want the create level sequence player part and set variable in begin play, right now it still creates a new one everytime you press the button

[obtuse herald]

that is the clean way

[eternal reef]

get the variable, place it in the blueprint and rightclick it and pick validated get

[manic wigeon]

can someone show me how because im trying to figure out how to call it

[manic wigeon]

ok

dont see it

ok found it

so i remove fliflop

[manic wigeon]

its still restarting and flopping to one area to another

[obtuse herald]

show me what you did

[manic wigeon]

your is valid is differnet then mine i couldnt find it

[obtuse herald]

they do the same

[obtuse herald]

that should work tho

[manic wigeon]

its like switching to restarting and resuming somehow

[obtuse herald]

oh

you probably want the pause node instead of the stop node?

[manic wigeon]

well i want it to pause

and then continue

so ye

[obtuse herald]

or stop at current time

one of these two will probably do what you want

[manic wigeon]

tried this but didnt work

[obtuse herald]

then try 'Stop at Current Time'

[manic wigeon]

i wish i can record

so i can show wtf this shit doin

its like moving back and hopping 2 steps forward

[manic wigeon]

let me tell you what its doing

so when i press space

when i press space its restarting. and if i press again it takes me a step after i was before i pressed it to restart

[obtuse herald]

which of these 2 nodes are you using right now?

[obtuse herald]

Oh

[obtuse herald]

do you have a Level Seqeunce somewhere in your level?

thats probably starting aswell

[manic wigeon]

i have one but a different one

not this one

i have a camera

but not a sequence

[obtuse herald]

yeah thats fine

so when you press play it immediatly starts the level sequence?

[manic wigeon]

nono when i click on a button on the widget

it takes me to a scenematic

[obtuse herald]

show me your widget

[obtuse herald]

I meant the blueprints of it

[obtuse herald]

yeah that makes sense

you are creating another sequence player in your widget blueprint

[manic wigeon]

because im trying to assigning it

to the button

in the widget

[obtuse herald]

yeah

[manic wigeon]

so i want that when i press it

[obtuse herald]

go inside your character BP

right click -> 'Add Custom Event'

[obtuse herald]

give your Custom event a fancy name

and connect it with validated get

then, in your widget bp

right click -> "get player pawn"

drag the return value -> "cast to first person charecter"

drag the return value -> "call <your event's fancy name>"

BP:

Widget:

@manic wigeon

[manic wigeon]

but how do you since it to my current code for all 3 buttons?

[obtuse herald]

are these 3 diffrent sequences?

[manic wigeon]

they are all buttons that are suppost to play the same sequence

shall i remove the character bp one and do the same for all 3 buttons instead in widget bp?

[obtuse herald]

no

just copy that to all of your buttons

'Cast To NewBlueprint' is 'Cast To FirstPersonCharacter' for you

[manic wigeon]

ye its still doing the hopping from one place to another

i think the flipflop needs different connections

maybe because its still calling the sequence player twice

?

[obtuse herald]

yeah

remove that

[manic wigeon]

remove what?

the sequence player from all buttons

?

[obtuse herald]

that

and connect the cast node directly to your button events

[manic wigeon]

what do you reference istead of the player?

character or sequence

[obtuse herald]

what do you mean?

[obtuse herald]

remove these two aswell

[manic wigeon]

still doing it

now its stopping scenematic and sending me to player
