blueprint

[cinder stratus]

Because I can just do some operations on the right stick axis to get the desired offset

[true valve]

Anybody knows how to fix the camera clipping through the walls?

[gentle urchin]

If its connected to a springarm, then thats the rotation you'd change. If the camera is unattached you need to calculate desired transform

@cinder stratus

[cinder stratus]

It's connected through the springarm, but still when I use setRelativeRotation it moves around itself, look

Here

This is actually the intended behaviour, then I also want to add a slight rotation around the character, but as you see using relativeRotation is used to move it around itself, at least as far as this code goes

This is kind of the effect that I'd want (emulated by moving the mouse), for now I've implemented the rotation around the center of the camera, but not the one around the character, this is why I'm asking

Of course not as extreme but it's hard to emulate using the mouse

[weary lantern]

Is there a node to convert from Rotator to Quaternion in blueprint?

[icy dragon]

I don't think so, but there's an option to take shortest path when interping Rotators

[onyx pawn]

trying to find how to add the set initial mouse position

[weary kettle]

hi everyone i am running with this problem did anyone how to fix

[alpine lotus]

I did realize that I didn't have the executables there when I was trying to fall asleep, I didn't have the player detection, I didn't think I need it for just 1 player in the game
I don't quite get what you mean with 3
And yeah I wasn't sure that the get console vatiable did what I thought

Your solution sounds quite simple actually

[alpine lotus]

@dawn gazelle I'm not sure i did it exactly as you thought... it works, but it seems to lag the game every here and there... like I get lag sometimes when turning around

wait... the top setup may be better?

I mean the top one makes more sense to me... on the bottom one... like where does it get the condition

[alpine lotus]

the top solution doesn't lag

true

works great

and I learned how to use variables better now

I understand more

[shell ember]

HI any idea how to check the addMovementInput node definition ?

[crude sun]

Hey so I'm having a weird problem with a timer

The timer itself functions perfectly fine

the only problem is that I want it to start at 4 minutes

and when I connect that to the BeginPlay event, it doesn't work

Anybody know what's going on here?

[gentle urchin]

Using tick with a delay is not the intended use of tick, it'd be better to put it in a looping timer

[obtuse herald]

No, the delay ignores input until it's done

Except for retriggerable ofc

[gritty elm]

set hardware cursor is not working in package build

how to solve this

but the cursor works in editor

why it doesn't works in package build?

my cursor.png is already in correct directory : /Slate/cursor.png

ok so i think the issue was solved by enabling blueprint nativization

[high ocean]

does anyone know if 4.26 fixed any of the issues related to custom structs? I'm getting an unknown struct after modifying it which fails cooking. Works fine in stand-alone, just doesn't cook.

[barren flower]

Does anyone here have experience with livelink? Every time I launch the editor I have to go into the livelink plugin and set it up again for the input. If I bake and release the project, how does that work?

[high ocean]

@barren flowerthere are many livelinks - you should probably ask in the channel closer to the issue you are experiencing.

[alpine lotus]

how do you apply a texture when it's in a class blueprinbt?

cause my doors have no texture

[barren flower]

If you scroll down, you can still select the properties of the door

but you have to have the component selected

[alpine lotus]

I don't see it

here right?

[barren flower]

From memory I think maybe you need to expand the child actor component there

[alpine lotus]

what is it called I can search for it

[barren flower]

its in your screenshot there

Under the child actor component heading

[boreal tundra]

I want the engine to check what weapon is in hand so it displays and uses the right ammo, what variable can I use for that, I want a branch to check, if variable equals to a particular actor than I want to use a specific ammo

[alpine lotus]

where?

[barren flower]

Yeah, so you are trying to edit the static mesh actor, right?

im working off memory here, but whats under that

[alpine lotus]

there's a lot

[barren flower]

really?

.....

Static mesh

[alpine lotus]

yeah but that's the door not the material

[barren flower]

I mean, maybe just search material in the search up the very top

[alpine lotus]

oh I got it I think

[barren flower]

Mine just comes up when I select the static mesh component

[alpine lotus]

thanks for helping me find it, I accidentally deleted some stuff... so I couldn't figure out how to add it back

I had to double click it

[alpine lotus]

to open the editor thing

this thing

and here I can change it

[barren flower]

Oh, so you dont want to change it in blueprint, you want to texture it globally

You should still have material slots available from inside the blueprint though

[alpine lotus]

it changed it in the blueprint too tho

maybe it's cause the doors are grouped under a arrow

[gusty shuttle]

Quick question: what's the best way to find out if a projectile like a Super Mario up down lavaball, how to find out when it reaches it's apex height. I want to figure out it so I can change a flipbook inside the projectile to point downwards.

[dawn gazelle]

Looks to be just a Vector2D variable. You can get the float inputs to show up like that by right clicking on the input pin of the set node and selecting "Split Struct Pin".

Hey guys, hope you are having a great night, I would like to ask if someone knows how to cowork in UE4 I hear something about Multi-User or something like that but I think its more local, I'm working with a friend that I know him in real life, lives in the same country but his a bit far from my house, we want to create blueprints together and that stuff, it's there any kind of tool to do that?
If you can send me a DM

[dawn gazelle]

A structure variable is just data - it doesn't exist as an object, rather it is part of an object.

Correct. They aren't objects, so they can't be added to an object array.

[alpine lotus]

when I use emissive static lighting within a blueprint it doesn't work

but when it's not in a blueprint it does

???

it's not lighting up anything like this as you can see

[hybrid ether]

Can somebody help me. What is best way to set actor active in level blueprint. In my game after I kill boss -> teleport should get activated. Atm I'm using this (image) but you can still interact because It's only invisible.

[hushed pewter]

Is there a way i can search Set variable across all of my blueprints

Its driving me nuts but my variable keeps getting set too 500 despite all the controlers having 0

[dawn gazelle]

Find one of your variable set or get nodes, right click and select "Find References". On the find results tab that pops up, click the Binoculars on the right side and it'll search all blueprints.

[marble nova]

Hey, im struggling to understand animation BP & character BP variables. Im using a trace to detect ledges, and i want for example to set a boolean on the character 'Climbing = 1' for example - and then use that variable in the animation BP to set the right animation. How do i pass variables between the two? all the info i'm finding just uses speed to set a new variable within the anim BP for walk/run

[obtuse herald]

You can use get(a ref) to directly change the variables without the need of removing the reference and adding the copy to the array

[dawn gazelle]

Sure? But this does require an actor to be spawned to contain the data - the character.

[obtuse herald]

Your weapon inventory needs to have weapons in it already, because you're only changing an existing item

Yeah

[open pawn]

So when I get a camera and SetAspectRatio to ViewportSizeX / ViewportSizeY on a buttonpress it works as expected but when I do it on BeginPlay it sets it to 0 and in the Construction Script it sets it to 1. Anyone know why this would be the case? Or how I would be able to set the correct Aspect ratio at the start?

[trim matrix]

i have a game i done where i shoot rockets at other players. i love to do a rocket that makes my character switch place location with the player the rocket hits. can anyone help me with this?

[severe turret]

@trim matrix if the rocket is a pawn, you can possess it. If not, you can add a camera to it (use a spring arm so it's not shaky as the spring arm can lag to deflect the inertial movement) and use Set View Target With Blend to switch to it.

[trim matrix]

@severe turret I meant i switch place with the other player

[severe turret]

sure you can de-possess each player and re-possess with each other's pawn

[trim matrix]

Ohhh i see i will try that

[obtuse herald]

Then you are switching the whole character tho (possible including inventory etc, depends on implementation)

[severe turret]

indeed

you could use proxy pawns for this purpose

[obtuse herald]

Or just swtich the location

[severe turret]

good catch there ToyB. I'm still waking up 🙂

[trim matrix]

i would prefer switcg just their location

[obtuse herald]

Save the location of Player A, teleport Player A to Player B, and then teleport Player B to the saved location

[trim matrix]

the rocket is a bp, the place location is in character bp , no idea how t get proper values of my the player characters

[dawn gazelle]

Create a variable referencing your character BP type within the Rocket BP and set it to Expose on Spawn. When spawning the rocket, you should then be able to feed in a reference of the player who is firing it into the rocket. When the rocket hits the other character, then you should be getting a reference of the hit character on the rocket (On your Hit or Overlap event). So now you have reference to both characters in your Rocket BP, so from those character references you should be able to get their world locations and then have the rocket switch their locations before destroying itself.

[trim matrix]

i will try that

nothing happends it seems, no clue what i done wrong

[blazing wasp]

hello - i'm trying to spawn an NPC and insert some data from a data table, but the array "get" doesn't seem to be working

i can see that "random integer" is picking a sensible value, and if i mouse ove r"Out Row Names" I see the two options in my table ("Alice" and "Bob"), but the output of the GET is empty

[supple dome]

probably its just the debugger failing

try using a print string

[blazing wasp]

oof, yep. so the debugger is pretty unreliable outside of breakpoints huh?

[severe geyser]

hey folks, I copied a folder into my content folder. It has lots of different sound wave files. When I try to add a sound notify into an animation and use one of these sound waves/cues, it will not allow me to add it in. Is there something I am missing?

I am able to to play sound in a blueprint

[obtuse herald]

You need to Import them through the editor

[severe geyser]

but not when calling a play sound on animation

they have been imported

[obtuse herald]

Oh

[severe geyser]

yeah it's weird

in the details panel, I dropdown and pick the sound but it reverts back to none. I am able to load in other sounds, just not the new ones

alright, so it was something with the location. I moved the file into a folder where I have other sounds and it now works

[spark steppe]

should show you what it expects when you hover over the pin

[thorny hatch]

Any1 who got an idea why this is happening? https://streamable.com/58rdzx

[last abyss]

It's very difficult to say, you don't show enough of the code that is changing the animation. The reason it creates an infinite loop error is because you're calling a function that's calling itself over and over with no escape.

[thorny hatch]

yeah i know i can send a screen shot of the changing animation if u want

[boreal tundra]

I want the engine to check what weapon is in hand so it displays and uses the right ammo, what variable can I use for that, I want a branch to check, if variable equals to a particular actor than I want to use a specific ammo

[thorny hatch]

I use a macro to get what weapond that is in our hand

but @last abyss You mean like from the anim bp

[last abyss]

maybe, mostly my guess is what is happening in either pickup or updategunattachment would be the issue

[obtuse herald]

Maybe you want a map variable
https://docs.unrealengine.com/en-US/ProgrammingAndScripting/Blueprints/UserGuide/Maps/index.html

[boreal tundra]

I'm not sure but if you make a bool to see if a weapon is in hand, you can than make a branch to check if it's true and if so you can play the animation

[boreal tundra]

I'll check

thank you

[thorny hatch]

@last abyss I just blend them by pose int and then i made a interface to be able to call it

This is how it looks on every idle, walk, sprint

[last abyss]

If you have a base weapon bp, perhaps you could add an identifier to it (like an integer?) and do a switch on integer?

[boreal tundra]

I'll try that too

[boreal tundra]

but I was looking for something that won't require lots of branches, like one node to see which weapon is in hand and switch to the proper ammo

[last abyss]

Yeah that's fine, the problem is in setting the blendspace int, specifically either of the functions in your player.

[obtuse herald]

You can also store the ammo type in the weapon itself

then just retrive the ammo type from the weapon instance

[thorny hatch]

@last abyss You know what i should do or nah

[boreal tundra]

but than I'll have to disable all other ammo, and I'd need the same all round check

[last abyss]

Like i said, it's hard to understand what you're doing in your bp because you're only showing a small part of it (your player's bp that is, and more specifically the 2 functions that could cause the issue; pickup and updategunattachments) you should look into those 2 and try to see if there's something that could cause an issue there.

[boreal tundra]

Is there a fully made game that is open source, so I can check how stuff are done?

Okay folks, I have a spline, at each point in the spline I want to fire off a sound effect. How does one go about this? Any keywords or straight up ways of doing this?

Is there a way to find out if a spline point has been reached?

[trim matrix]

is it possible to achieve actual loading without level streaming? and a live percent counter instead of freezing for a couple seconds?

[gusty shuttle]

You would need C++ for that

[severe turret]

@trim matrix you could try my Latent Level Streaming Node plugin. No need to code anything then

[indigo bough]

Hey folks, here again with another gap in my logic!

I have a need to create a component within an Actor that has it's own blueprint logic, which can provide it's variable data to the parent Actor, however the component requires an understanding of it's world transform and it's relative transform within it's parent Actor. Would an Actor Component do this? My main concern is they don't have any visual representation, so they would have to live disconnected from the visual representation they have inside the Parent Actor, which is a bit messy.

These 'components' represent individual ship sails (not masts, but each bit of cloth), and they all run calculations, which the parent actor needs the result of.

But the issue with Actor Components is, they would be attached to the parent 'Ship Actor' but not actually responsible for the sail mesh/etc.?

[twilit heath]

if they are using the owner's root components' location ActorComponent is fine

if not, you'll need at least SceneComponent

[indigo bough]

And the SceneComponent would be a relative offset from the owners root component location?

(I can try this, though, thanks)

[twilit heath]

scene component has its own location

[indigo bough]

Nice okay, but still doesn't have any visual element (mesh component, for example?)

[twilit heath]

now if you need more functionality

like collisions, then its at least PrimitiveComponent

if you want visuals, then its some form of MeshComponent, depending on what it needs to do

[indigo bough]

Hmmm, maybe I can get all bones in my sail meshes within the owner Actor, and then spawn/attach a SceneComponent to each of the bone locations

Trying to automate this so the setup is a bit easier per Ship

But that would probably do it, even if you had to add a tag to the sail SkeletalMesh components in the owner Actor

Okay, thank you. Understanding the difference between those components really helps 🙂

[patent bane]

i feel like my code doesnt find the socket to attach the object to. I can make it work in the blueprint editor, but when i use attach actor to actor, it's like it's not finding the socket

[keen hearth]

Is there anyway to select multiple bitmask choices in a Datatable?
I can setup an Enum and mark it as Bitmask and add that to a Structure, but the Datatable only presents a standard Enum interface for flagging a single option.
The Bitmask Blueprint node does present an option to select multiple entries though.
I'm wondering if there might be a way to format the cell in Excel and define the choices that way.

[placid mirage]

How to make the correct direction of movement when falling?

[severe turret]

@placid mirage https://www.youtube.com/watch?v=yMdQ-W4SiAE

this kind of maths would work.

also https://docs.unrealengine.com/en-US/BlueprintAPI/Game/PredictProjectilePathByObjectTyp-/index.html

[placid mirage]

Thank you!

[wind sequoia]

Wdym u could do this as if it was the details panel should have no issue

[placid mirage]

Predict Projectile Path is suitable for gameplay statics, have any thoughts on how to keep the Z axis velocity when falling?

[severe turret]

know the rate of gravity and apply to the velocity over time to terminal velocity

[violet flax]

Hey, when you use "make array" to create a new Array while playing, for something like a "Weapon Setup" in Call of Duty or a "Deck of Cards" for Magic and Hearthstone. How can you give that Array a Name? So you can reference it later?

[dawn gazelle]

Create an array variable and set it into that variable.

[obtuse herald]

You can create a variable and assing make array to that

[placid mirage]

when using CharacterMovement, the player completely loses velocity the Z axis, manimulation with gravity here cannot be. 😔

[severe turret]

oh I don't know about that. I rarely use the CMC

[dawn gazelle]

eg.

[obtuse herald]

Do you just want your character to "fly" along the blue trajectory?

[placid mirage]

Yes!

[placid mirage]

do you know how to do it?

[obtuse herald]

I have 2 ideas in mind, first is to launch your character in that direction to get more velocity (possibly with a keybind) or you turn down the gravity scale of your movement component

[obtuse herald]

https://docs.unrealengine.com/en-US/BlueprintAPI/Character/LaunchCharacter/index.html

[violet flax]

@dawn gazelle @obtuse herald I mean the player should give the array a name. For example he creates a new Deck with 40 cards.
When he starts playing he needs to choose a deck. So he gives the new deck the Name "Deck One". So i would need to take that "string/name" and would assing that to the new made array to later find it again.

Or am i doing something wrong here?

If i create a new variable array i would inside of the editor give that array a name.

[obtuse herald]

Or make a struct which contains only the array, and use a map variable with string as key

[spark steppe]

or an uobject, which are more reliable in my experience nvm, sounds like something that wants to be saved at some point, so a struct is easier to handle

[keen hearth]

Top is how it shows up in the data table editor. If I select the bitmask in blueprints I see the multi option dialogue.

[restive ore]

I'm learning blueprints and I now understand the basics of booleans, variables, functions, arrays and stuff. What should I learn next?

[obtuse herald]

References and OOP if you're not familiar with it

After that I would suggest timer and events

then how UE4 handles player and game stuff (i.e. PlayerController, PlayerPawn, GameMode)

[wind sequoia]

Ur using an integer and that has the check right

?

[placid mirage]

Thank you! I managed to implement my plan using Launch Character 🥳

[keen hearth]

I might be getting it wrong. I created an enum and ticked the bitmask bool, then I added it to my data structure as an entry.
Do I just need to add an integer to my data structure and then when I'm using the data compare it to the bitmask? I guess that would work I'd just need to figure out the right integers for each item in the data table externally and then put them in.

[wind sequoia]

yes look up the docs on bitmasks

[modern cove]

I was trying to organize my game's item objects by moving them into their own folder. It apparently caused this bit of damage:

How do I un-break this while keeping my organization intact?

[dawn gazelle]

Right click on the item structure that's having the error and select refresh pins?

[obtuse herald]

There was a way to reload blueprints by rightclicking them in the content browser

but I forgot how it's called

ahh, it's 'Asset Actions -> Reload'

[modern cove]

I tried a Refresh Nodes on the GetClassDefaults; it causes the outgoing wire to vanish. I'm gonna try the Asset Action Reload next

[dawn gazelle]

There's a setting on the side

[modern cove]

no go on the Reload

unless you mean the objects I moved; reload those?

[obtuse herald]

Try it

[boreal tundra]

why am I getting this error and how could I fix it

[dawn gazelle]

Probably because you are combining two execution paths. Have two return nodes after the sets.

[boreal tundra]

there is a sequence to determine which to run, so they are sepperate

[boreal tundra]

how can I fix it than

[dawn gazelle]

Use a return node on each path. Do not combine them.

[obtuse herald]

that shouldn't matter actually in this setup

unless i'm missing something

[boreal tundra]

the none is coming from the second one, but the second one shouldn't even run

[dawn gazelle]

It does, because blueprints work backwards.

Your comparison of the OR there is calling the values from the nodes behind it.

[keen hearth]

The error looks like you're not providing the character. Is this a multiplayer situation? Could you be trying to get it on the client and not the server?

[obtuse herald]

oh yeah ofc

🧠

[boreal tundra]

no it's just to check which ammo quantity to use

for different weapons

[modern cove]

Reload didn't fix it. I can't seem to get the Class Item from that Struct to connect to a GetClassDefaults Node. When I try to make a separate node for GetClassDefaults it won't let me connect the class wire; gives me the red /

[boreal tundra]

you mean drop the or and put different nodes?

[obtuse herald]

make 2 return nodes

one for each execution pin

no or gate

[keen hearth]

copy and paste the return node and hook one up to each and remove the or.

[boreal tundra]

I'll check, one sec

I think it worked

thank you all

[limber seal]

Hoping somebody can help me out with this 🙂 I have an actor moving along a spline to a target location. What I am doing here is attempting to apply the formula for Speed = Distance/Time. So I set a time of 60 seconds, and get the length of the spline (distance) in unreal units which correspond to centimeters. I divide the length by the time, and set the speed to this result.

My problem is that the speeds it is setting do not line up with the times I am entering. The speed should be set in this case to a speed that would make the actor reach the location in a time of 60 seconds. For me it is taking ~50 seconds. If I try 180 seconds, It reaches the location in about ~150 seconds.

[obtuse herald]

speed is the change of position / change of time

that means your speed is the amount of positional change / world delta seconds

[limber seal]

The issue ended up being that I was being stupid and had the target underground 😂😂 but I appreciate you trying to help

[blazing wasp]

I have a Map of {Name, CustomDataStruct} to keep track of a set of objects, and whenever I add an element with a new key, its replacing an element with a different key. Specifically, I'll add {Bob, CustomDataStruct} and then add {Alice, CustomDataStruct} and upon adding the {Alice, CustomDataStruct} pair, the Bob element disappears. I end up with a Map with 1 element, rather than the expected 2. Any thoughts?

[dawn gazelle]

That shouldn't be happening 😛

[blazing wasp]

agreed! I've confirmed with a debug string print that the keys are different 😦

[obtuse herald]

Do you only print one key?

[blazing wasp]

I'm printing every time I add an element. First time it says "Adding Bob" and the second time it says "Adding Alice"

[obtuse herald]

Make the Map a public variable, click play in viewport and then click on your actor, the map will update in runtime in the details panel

[blazing wasp]

Yep I've done that. It goes from 1 element with {Bob, CustomDataStruct} to 1 element with {Alice, CustomDataStruct}

[obtuse herald]

👁️ 👄 👁️

Does this happen aswell with other maps?

[blazing wasp]

not sure, that's the only place i'm using a map

[obtuse herald]

try it

create a new one and add two elemnts

[blazing wasp]

ok couple mins to set it up

[boreal tundra]

does anyone knows what should my object be?

[blazing wasp]

@obtuse herald ok it worked fine with a test map

this added 2 elements of {0, 1.0} and {1, 2.0}

😦

[obtuse herald]

Then you probably have some bug in your code

[obtuse herald]

?

[boreal tundra]

I'm trying to cast but I don't know what my object should be

[obtuse herald]

You need a reference

of the object you want to change

[boreal tundra]

I just want to change variables

[obtuse herald]

Casting is useful to convert a reference type to another reference type (ie. Pawn -> BP_MyPlayerPawn)

[boreal tundra]

does that mean I shouldn't cast in this situation???

[obtuse herald]

https://docs.unrealengine.com/en-US/ProgrammingAndScripting/ProgrammingWithCPP/ReferenceAssets/index.html

[boreal tundra]

should I make an actor variable instead?

[dawn gazelle]

Casting is a means of taking a less specific class reference and making it more specific. For example, you could take an Actor reference and Cast to Third Person Character. It does allow you to access the variables and functions within the casted to class, however, it's not meant to be a means of getting a reference to the thing that you're trying to change.

[sand shore]

Additionally, casting does not alter the referenced object. You cannot take a reference to an actual AActor (GetClass() returns the same class as AActor::StaticClass()) and cast it into Third Person Character. Casting gives you a typecast copy of the pointer/reference, nothing more, so you would have to be referencing an instance of Third Person Character already (even though the type of your pointer would be AActor).

And I still think "Cast To" shoulda been "Cast As"; especially when the cast node's result pin is "As [NewType]".

[boreal tundra]

I keep getting this error and I don't understand why

[blazing wasp]

@obtuse herald figured it out, the Map was a member of a data struct and i was writing over the data struct!

ty for the help

[dawn gazelle]

Not sure about the equipped weapon one, but the "As Weapon Base" one, in your screenshot you're literally setting it to nothing before using it.

Perhaps you meant to get it instead?

[boreal tundra]

I did set it to the blueprint, and than delete it

I'm not sure if that works, but I tried other ways and I still got the same error

[boreal tundra]

what node should I use to set it

[dawn gazelle]

It's not about what node to use to set it.

From what I can see, you're trying to display the Total Ammo value off of a variable named "As Weapon Base". I don't know what the type of variable "As Weapon Base" is, but I can imagine, it's probably a "Weapon Base" reference. So, even though you have a variable called "As Weapon Base" that is available to store a reference to a "Weapon Base" object, it doesn't mean you've provided the actual reference to the object that is actually storing the data that you're trying to access.

Ie. Just because you created a blueprint doesn't mean that thing now exists in the game world - it has to be spawned and exist as an object in your game. If it exists in the game somewhere, you'd be the one to know where it exists or how it at least was created and you have to get that reference of its existence into your widget. If it doesn't exist, then you can't reference it to get the value into your widget.

As ToyB-Chan has already recommended - you need to learn how to get references to objects which is a bit of a complex topic.

[boreal tundra]

I don't need to spawn that object in the world, so would changing the blueprint type to something like the thirdpersongamemode would work?

[boreal tundra]

I will be trying to learn about that

[quiet stag]

Can someone tell me why i would use a blueprint with a public data asset vs just a blueprint for creating different objects

[regal venture]

With a primary data asset?

If something is only data, and doesn't actually need any of its own functionality, then a data asset is usually the way to go.

They don't need to be compiled, they're easier to work with, and they make their intentions more known

They're just read, and the blueprint does what it needs to do

They're more lightweight and clean

[ember veldt]

They also support inheritance as well, so you can have a lot of functionality tucked into them in a hierarchy

[regal venture]

For an inventory UI, should I be grabbing and slotting each item in the inventory on the UI's construct, or do it once on initialization, then bind to an event on the inventory (for adding more)?

I'm not sure how long the inventory UI data actually sticks around, and if I can count on that

[ember veldt]

Ive got mine tied on init, then listens for an update event on the component its tied to. Seems alright but my implementation forces a clear and refill each change since its a simple array

[regal venture]

So your array and UI does stay around to continue being subscribed to that compoennt?

[ember veldt]

The UI is fed a reference to the inventory component and it does everything from there. The inventory data is constant within it's actor's component

[regal venture]

So the actor's component tracks the UI data in your setup?

In mine, the actor's inventory doesn't know about anything UI related, the UI just grabs data from the inventory component and listens for an event:

I just don't know if that event binding will last indefinitely or what

Or if eventually that UI object gets deleted

[ember veldt]

We're doing the same thing. The component doesn't know anything about the UI. It just fires a dispatch when it updates. Event bindings don't expire unless either object is garbage collected AFIAK

[regal venture]

And there is no reason it'd normally get cleaned up like that?

I know it doesn't actually exist until you open that UI screen for the first time

But then it just stays forever thereafter?

[ember veldt]

Shouldn't be, but some testing should be done. As long as it's referenced somewhere

[regal venture]

Well, presuming it does, then I guess OnInitialized will get called again when it gets opened, right?

So it'll do the reassignment of slots and resubscription then

[ember veldt]

And if your widget is being destroyed it shouldn't matter anyway. Just reinstate it when it's called to open again

[regal venture]

So I guess that's kind of fail-proof in that regard

[ember veldt]

So your implementation should be fine regardless

[regal venture]

Okay, cool. Just wanted a sanity check. Subscribing to an event on the inventory made sense to me, but I'm not really sure what standard ways of going about this are

Thank you! 👍

[chilly jetty]

Hi there
I have this shield that I made which can block a projectile and increase the ammo count
it works fine but when i activate it again after the first projectile catch even without catching the next projectile, it automatically increases the ammo count

is there a way for me to have it where when i press the e key it has to wait and see if the OnComponentHit event is true all the time?:

instead of just checking once

[dawn gazelle]

Use a gate. E opens the gate, and the on component hit "enters" it. Then you just need something that closes it again. (like your E event)

[late shuttle]

Good evening, gents.

Anyone know of a way to render a collision sphere with a slightly emissive colour? Just as it's seen in editor...

[trim matrix]

I have an interact function in my player controller that checks if the E key is press, if it is, it sends out a line trace from the player's camera, and if it hits an object with an interaction interface, it calls the event. How can I tell the game to do either a simple press interaction, a spam interaction, or a hold interaction?

Please ping me if anyone replies to my issue

[late shuttle]

When pressed I would run a type of check state for X float duration every Y intervals during that duration to detect what the key is doing.

You could keep track of an integer that shows how many times the interact key is released.

As well as a float for the duration.

[dawn gazelle]

Very basic way with no other checks for getting a "hold" style of interaction.

[dawn gazelle]

For a basic spam you could use a timer as well set to the threshold of what you want to spam (in my example below, set to 0.25s). When the interact event comes through you increment a counter, and check against a maximum amount of spam presses you want to reach.

[solid grove]

How do I check if a passed in actor is of a class I want without having to cast

I don't need to access any logic

of the class

just need to check whether it is of that class or not

[solid grove]

@dawn gazelle this doesn't make a hard reference to the class does it?

[chilly jetty]

Cool thanks for the tip!

[trim matrix]

@dawn gazelle ok but how can i set what objects to do what interaction types?

Like one actor do spam interaction, and another do press

[dawn gazelle]

Different actors can react differently to the interface you've created.

[trim matrix]

Oh yeah true

So i can just put the interaction type logic in a specific actor's interface action and ve good to go?

[dawn gazelle]

Not sure what you're asking or what the answer would be 😦

[dawn gazelle]

Yep

[dawn gazelle]

If I'd fathom a guess based on what I'm reading right now, then the answer would be yes as it's a hard class reference you're getting from that node.

[solid grove]

eh I'll just use get player pawn == then

I really don't want to make a reference the the main character class

[uneven geode]

Hi can someone give me some advice? I want to login level (pc) -> actual vr game (vr) but even if i execute console command stereo On doesnt seem to work

Any idea of how to Change from pc mode to vrmode ingame?

[crude sun]

Hey I'm having a weird issue in my gamemode blueprint

I'm trying to set a value at begin play, but it doesn't do anything

What am I doing wrong?

[knotty bane]

do you use the correct variable in your widget? add a printstring to the timemin after createwidget (+ and testing in tick?), you can also set the 4 as default for the variable - then you don't need to set it on beginplay.

[crude sun]

Yeah changing the default value was what fixed it

I'm still very confused as to why I couldn't set a value through the beginplay

[knotty bane]

I guess you're not running server/client? because gamemmode exists only on the server, and you're widget is clientonly

[crude sun]

Alright thanks,

I have one more question

I'm trying to trigger an event in this blueprint when my character passes through a bounding box

I'm just going to turn all the remaining seconds into points

any idea on how I can do this?

[knotty bane]

you're showing only little part of your blueprint. but you should calculate something like "remaining mins*60 + remaining secs", this should give you the sum for your points

[crude sun]

just to clarify, I know how I'm going to turn the time into points

I just need a way to trigger that with a bounding box

[knotty bane]

ah. I would suggest an actor with a trigger volume attached, in there the onOverlap Event you can get your gamemmode and do the math. or fire a event in the gamemmode which calcs the points and updates you ui and gameflow.

you can also use levelBP for that - depending on what's your favor - then you don't need a seperate actor, you can reference you levels existing actors

[wise raven]

Primitive components are not showing in the GetComponentsByTag ?

[high phoenix]

when I simulate physics on my character's Mesh it goes throught the ground. anybody knows why?

[wheat vigil]

how do i set the lods screen sizes of a mesh?

[tame pecan]

@wheat vigil

in the static mesh

[bright dirge]

Hello, is there an event in gamemode i can override to handle spawning without using PlayerStart actors ?

[humble island]

Nope. Gamemode by default relies on Player Starts.

[bright dirge]

So if I want to do a spawning area actor, said spawning area will have to spawn player start actors ?

[humble island]

You have to manually devise a Function/System that does that.

1. Remove Default Pawn from GM.
2. Search for Location on Event New Player.
3. Spawn Player Actor from Class & Possess.
4. Done.

[wheat vigil]

I mean in blueprint language ;)

[bright dirge]

so the new player event is OnPostLogin

[tame pecan]

@wheat vigil That's not possible. You got to do some c++ extensions.

[wheat vigil]

Oh ok, and how would i do thati c++?

Every actor should have the same lod screen sizes

[tame pecan]

Every actor?

You mean every component?

[wheat vigil]

Yeah i have many meshactors that all have the same size

But the default values for the screen sizes dont work

[humble island]

PostLogin is after player has been assigned a controller (if I am not too wrong). You need New Player Event on something.

Not in front of PC.

[wheat vigil]

I spawn the meshactors via blueprint

[bright dirge]

Couldn't find the new player event but when connecting my respawn function to OnPostLogin it seems to work for the first spawn and the rest of the time i will directly call my respawn function so its seems good

[humble island]

As long as it works. 👍👍👍

[bright dirge]

Yep thanks

[pseudo pelican]

#ue4-general message

[gentle urchin]

@bright dirge

[bright dirge]

Thanks, found it a bit later and I indeed need to use this one has OnPostLogin doesn't trigger after seamless travel apparently

[gentle urchin]

I think swap might be called during seamless?

[bright dirge]

Yep but HandleStartingNewPlayer work in both case so no bother

[gentle urchin]

True that

Its the correct one to use

[regal venture]

Is it not possible to bind a function to an event being broadcast by its own class? I'm just getting this node, instead of anything that allows me to bind a function/event to it:

[bright dirge]

If I am not mistaken you are trying to create on event in a function instead of in the event graph

[regal venture]

@bright dirge indeed, but that hasn't caused me any issues before - I just bind to functions, like this:

EVENT_OnStaminaExhausted() being another function

[bright dirge]

Tried to do it and it worked for me

[regal venture]

wat

haha

...and now it's working for me, too. 😑

[bright dirge]

Magic

I am glad i could help you 😉

[regal venture]

Thank you for magicking my UE4 to health

I am guessing that I didn't compile the BP class after I created the event dispatchers, so it didn't have a signature to create a function from

That's on me

[icy dragon]

That's weird, because BPs automatically compile when starting PIE.

[alpine lotus]

I need somebody to help me... I am stuck on the same issue for days and more issues are piling up

for example... my class blueprint, I have a hallway segment in it... that has doors, so doors need to be move-able to open right... but the rest should be static... and so I have everything move-able for it to work... but then my thing breaks... so I set it all to static, save and compile and then set it t o move-able, save and compile

and then it's where I placed it in the world

[icy dragon]

What kind of "breaks" are you talking about?

[alpine lotus]

when it's set to move-able

all the things reset to like a default import position

aka the position the objects were in when I exported them from my 3D program

[alpine lotus]

happens every-time I open the project, or add new objects to the blueprint

or like edit the blueprint

[trim matrix]

Is there a node which adds constant movement to the game object to one direction?

[alpine lotus]

no

let me show you

this is the blueprint

this is how it is in my level

when I press play

they reset to the default positions

and I get this

[icy dragon]

Actually yes. Add World Location.

[trim matrix]

Thank you

[alpine lotus]

oh I thought they were asking me if I have it, lol

[trim matrix]

yah np 😄

[icy dragon]

Consider asaembling something like this directly in level instead of containing them inside BP.

[alpine lotus]

but that would take forever, isn't that the point of a blueprint, creating something you can easily replicate? copy? even into other levels?

with the same code mechanics

so you don't need to write the same code over and over

cause I have this for my doors and lights

and having to replicate this like 50x

for evrything

I have no construction script

I thought that was for adjusting values like colors or so

so how would I go about it... so that when I press play the blueprint stays in the position I placed it in

I know if it was set to static that it would

but then my doors wouldn't work

I can show you

[pastel rivet]

Is it possible to spesific (if you have two viewports) which window that does not capture on mouse click with a 3D widget?

I've currently have multiple viewports running, but i want one of the viewport to have an UMG (has to be 3D due to you cant spesifiy a spesific camera with a 2D widget)

[lone jewel]

I have a question im trying to spawn my character on another map but in the same position that was on the other map Let say my player Was on x = 1, y = 1 and z=1 of Map 1, i want to change the map to Map 2 and the same Coords

How can i do that

[alpine lotus]

I have arrows for the doors to open on... so even if I set everything to static, the arrows aren't

so I get this

[lone jewel]

like when i load the map i can determine the coords where my character will spawn?

[alpine lotus]

the hallways stay in place when they are static

but not the doors

lol funny how it says help there, accidentally captured a bit of the wallpaper on my other monitor

I just set them to that

it was all move-able before

well how else am I supposed to make doors rotate on a specific point?

I didn't quite manage to export the doors from my 3D software with the correct pivot

I tried quite a few times

so I can use the blank component

I will do that then

[quiet stag]

hey lorash!

lorash im sorry i was so stupid... all i needed was a call to super in that event that gets called when u change a property

like u were originally telling me lol

LOL

i know i was just sleep deprived lol

lorash i got a basic concept question as to the reason i was doing what i was doing...so basically i made one blueprint called health item...that has a data asset property...so i thought it would be nice since if i wanted to create varried health items...the data asset contains a staticmesh a pick up sound and health point strength...what do u think of that?

yeah i wanted to see what they look like when you place them around the world

[alpine lotus]

I dragged in a empty actor from the other screen

[quiet stag]

i didnt even need the onconstruction lol all i needed to do was have super called in that event changed overriden function

[alpine lotus]

ok ok ok

😅

yeah doing that now

yeah I found it, replacing the arrows now

I wanna first at least get the basics working, lol

or there isn't much to test if the stuff I'm doing is still kinda broken

one problem at a time, ahaha

[trim matrix]

guys, is it necessary for blueprint to be character type and have controller to add continous endless movement to one direction to it? trying to have obstacles moving towards you endlessly

[alpine lotus]

ok so I got rid of my arrows

doors still work

ima reload and see how it loads now

[trim matrix]

@trim matrix someone mentioned Add world position node for it, although it doesn't appear when blueprint is just actor.

[alpine lotus]

I set the doors and the empty ones to static, but then they don't open, but when move-able, the doors end up here

[icy dragon]

To add this, moving the player can lead to nasty floating point errors.

[alpine lotus]

yea they won't, but now my move-able doors are within a static category

[trim matrix]

Yes, i'm not moving player. i want to move obstacles towards player from differents sides. so it's not endless runner per se, but something very close to it.

[alpine lotus]

since the shared root is static

since the doors are under the root

[trim matrix]

problem isn't the player, problem is adding continous endless movement to obstacle actors.

i'm quite new to unreal so i don't know which node does that.

or if there even is such a node.

[alpine lotus]

I mean I guess the whole door thing could be a separate blueprint, but I thought that blueprints were for making stuff faster... in the way that you can easily copy paste the same class blueprint around and everything will work

I mean if you have lights in it, they work perfectly

so I thought doors would too

and I mean they do... but also then it all resets and doesn't stay where you placed it

and it's annoying how many hours I spent on this

like 20+hrs and I got basic lights, broken doors, and the world lighting doesn't work how I want it to

yeah they aren't

but then I have to place each door individually?

I don't really get the construction script... also

any way I can extract the doors from my existing blueprint to another one

without having to rebuild everything

like somehow copy the doors and the hitboxes and that

I created a scene component and managed to copy the door stuff over to a new blueprint, now I can also copy the code over

and it should be separate

I will need to redo my variables though

I mean I know you can use the construction script to like... for example set a different light color for each light or change it's size or so to have like individual parametres

but I didn't know you can use it to copy objects over?

will do

so anyway... if my doors are separate... they should work?

[dire reef]

Hey Mates
Does anyone know how can we create a hologram like this in material editor (HLSL) ?

[alpine lotus]

I mean the doors worked perfectly before when I managed to get them into place with my hacky method

ima have lunch, I will be back, if you are still here... I maybe may need help with something else... if it didn't get fixed by me separating the blueprint into 2

[dire reef]

i think i know which one you are talking about
but i opened content example project to double check if it is same thing that i checked or no!

TBH i tried this material experimental level 1.1 before but the result wasn't as i expected then i tried to use another way but i'm still unsuccessful
can you tell how can i get those paragon characters?

Ahaha if that so, let me check it
i think i've got in my package

@trim matrix Do u know which one of those Paragon chars used that implementing ?
cuz i checked and didn't recognized

[lone jewel]

How to teleport a player when spawning in a different level?

[dire reef]

that's what i reached
just bcuz of translucent the face goes like that!

[icy dragon]

I kinda prefer doing it by dither, but how's your nodes going through the Opacity input?

Most games using the hologram effect use masked opacity, and apply TAA dither to soften the opacity.

[alpine lotus]

so with my door blueprint... could I do something like... getting the doors relative location in the world and then setting it? so that my doors spawn in the location where I placed them in the world?
This doesn'twork btw

[shadow saddle]

how to let your character fall to the ground faster ? gravity scale doesnt do the job i tried

like simple jump , but fall down faster

instead of the default one

[alpine lotus]

wait what? like my doors don't spawn in where I placed them when I press play, so I thought I can set their location to spawn where they were placed

[shadow saddle]

move chara directly as in bp manupulation

or wasd

[alpine lotus]

so how do I make a moveable object spawn in the spot I placed it into?

it's not, it goes to the default location

hmmm

but there's nothing in my code setting the location

just rotation to open them

[dire reef]

as this is an old project
so i forget the reason but i can remember that at first i tried Dither
not sure but cuz this is ar project for android i think mobile didn't support that kind of staff

[alpine lotus]

well yeah, but why don't they spawn in the doorframe but here

I don't see anything in my code that would cause htis

[trim matrix]

I think i'm hardstuck, after watching several tutorials and trying all of them, spending hours on it, i still can't get this problem solved. So i want actor, which is nothing but a simple mesh as soon as it spawns, to start moving to one of the picked direction (either up,down, left or right) endlessly at the constant speed. Equivalent to adding constant force to the object or equivalent of input axis being pressed. Is there a node or very simple way which does exactly that?! i managed to do it using timelines, interp to movement and lerp, but vector calculations are spiderweb of a code.

[alpine lotus]

yeah but that's separate now

[dire reef]

🤔
it must be masked?

[gusty shuttle]

Hey folks, I'm making a 2D game and I'm hanging out at a more intensive area of the map. I took a screenshot of the stats. I don't know if they are good or bad haha

[alpine lotus]

I have just a door blueprint

just doors

and their collision box

k

[icy dragon]

Dithered transparency did require the transparency to be masked. Otherwise the effect will fall short.

Also I don't get it why on earth mobiles are less capable to masked opacity materials.

[obtuse herald]

didn't we already had that? you can't attach a movable actor component to a static actor in runtime

[trim matrix]

which node moves actor?

[alpine lotus]

but I'm not?

[icy dragon]

Add World Location or Set World Location

[obtuse herald]

these are the errors you're getting, right?

[trim matrix]

there's no add world location and/or set world location for the actor

[alpine lotus]

only this now

[obtuse herald]

yeah, set all your components to moveable

[alpine lotus]

I have this

all are moveable

[trim matrix]

if that was adressed to me, already have all components set to moveable. still no add/set world locaiton for actor.

[obtuse herald]

no no, it wasn't

[trim matrix]

oh ok

[alpine lotus]

don't get what's static?

[obtuse herald]

It's called 'AddActorWorldOffset'

[icy dragon]

I think next time I had to give fuzzy keywords instead of the exact node name.

[marsh citrus]

Hi guys, does someone know how i can do to when i click on a item it play a sound and then i have to wait for it to be finished to play it again ? Do Once maybe but how reset when sound is over ? thanks

[glacial viper]

hello i have an error when i finish to test the game and i have no idea where it comes from can someone help?

[alpine lotus]

I don't understand what's static in the doors

I checked all the components in the blueprint

they all are moveable

[alpine lotus]

I posted it here

the second half

[obtuse herald]

check your door blueprint as well

[alpine lotus]

I am in the door blueprint?

I don't have the doors in the hallway one anymore

[obtuse herald]

you have 1 doors bp, and 1 door bp, check both

the other way around i belive

[alpine lotus]

I only have 2 blueprints?

and then my doors

[dire reef]

but in this way i didn't use dither
check this out it's what exactly i need except face!
i think i should go back to dither ...

[alpine lotus]

but I don't have it attached like that anywhere?

like I checked the blueprints

all thse have moveable here

[obtuse herald]

You have to child actor components

[alpine lotus]

yes?

[obtuse herald]

and in that actor, something is probably static

[alpine lotus]

I clicked all the scenes, doors and boxes

all are moveable

[dire reef]

that can be a way as well
using element 0 for it's head
1 all other part

[icy dragon]

Try this setup.

[alpine lotus]

so like... the error says door and door 1 are static

but look

they are set to moveable

I don't get it

[obtuse herald]

it's an actor child component

and in that actor

there is probably something set to static

[alpine lotus]

oh you mean this?

[obtuse herald]

👁️ 👄 👁️

just use static mesh components

[alpine lotus]

so what do I set it to? I tried to set it to actor but then the doors became invisible

[obtuse herald]

don't use child actors for static meshes

delete them

and use static mesh components

[alpine lotus]

confused

I can't delete the doors?

[icy dragon]

Get rid of the child actor, use static mesh instead

[alpine lotus]

how?

[icy dragon]

Delete the Child Actor in your BP outliner, or whatever it is on the top left corner in your BP outliner, or delete the damn door.

[alpine lotus]

so I delete the door?

but then I have no door?

wait... I think I got it... how did my doors turn into child actors anyway

when i re-inport them into the blueprint they aren't

[icy dragon]

No door is better than having door.

Kidding. You can either have them in the map (which is WAY BETTER) or just program them in the same BP.

[alpine lotus]

but if they are in the map you have to program each individual door?

[icy dragon]

Do you really want to have one actor BP for every single door, when you can just have the same BP many times in the map?

[alpine lotus]

I thought that I make a class blueprint with doors and then just copy it everywhere I need it?

[obtuse herald]

you can

[icy dragon]

Yes, that's how you should do it.

[obtuse herald]

you just have to make sure that your mobility is correct

[alpine lotus]

why are doors so hard

[icy dragon]

Okay, a better rundown for you:
-> One actor BP for the wall generation
-> One actor BP for the door and its logic

[alpine lotus]

that's how I have it

just my doors are actors, I need to replace them

[icy dragon]

Now you can just put them doors inside the map, instead of having it nested inside another BP.

[alpine lotus]

yea

[obtuse herald]

^^^^

[alpine lotus]

that's the plan

[icy dragon]

This is what I keep calling as "Nesting"

[trim matrix]

I have a problem with something that i don't understand - So if i put my actor Which is nothing but mesh and collision box on scene and i press play, it shows in the game, but if i connect logic to event begin play in event graph and then disconnect all of the logic - actor in the game dissapears whenever i press play. Any idea what could be causing that?

[alpine lotus]

why are they bigggerrr

when I do the static mesh thing

[obtuse herald]

just scale it down

[alpine lotus]

they are way bigger than the original doors

that's annoying

[icy dragon]

Wait, why do you disconnect the logic?

[trim matrix]

@icy dragonTo check another logic but that's not the point, i don't understand why it dissapears without any logic in it if it was showing before i connected logic.

logic is simple eyecandy mesh manipulation, nothing complex.

[icy dragon]

BeginPlay only execute when the object is first spawned into the map, which also execute upon play.

[trim matrix]

u mean begin play also executes when i drag actor in the scene without pressing start game?

[icy dragon]

Just scale it down.

[obtuse herald]

no

[icy dragon]

No, that's Construction Script's doing.

[alpine lotus]

trying to, but I can't get the right sale

it's not half or quarter

it's some weird scale

[icy dragon]

Disable number snapping for the scaling in the top bar of the viewport.

[trim matrix]

then i don't understand - actor shows up without any logic, when i connect it to this logic, it works as it should, actor still shows up in the game, when i disconnect the logic, it dissapears.

[alpine lotus]

but then it won't be exact either

[icy dragon]

I don't know how you can't copy the scale vector from one mesh into another in BP.

[alpine lotus]

the scale is 1

?

like the doors in the blueprint are 1, in the level they are also 1 and the same size as the OG bluepring doors, but the new ones are bigger when I put them in the blueprint

but when I put new doors into the level they are the correct size

[azure bolt]

Hello i have this third person camera around a pawn, and i have it setup like this. But whenever i turn the camera to right above the pawn, it glitches out and (i think) the Y axis seems to blend between both the X axis and the Y axis. any idea how i can fix this?

[obtuse herald]

did you scale any of your parent components?

[alpine lotus]

don't think so

[trim matrix]

@azure boltyou can limit allowed look arc

[azure bolt]

Is that the clamp node?

[trim matrix]

u better do it with ur own math, more flexible but yeah clamp also can be used.

[alpine lotus]

I'm just gonna redo it

may be easier

[alpine lotus]

I accidentally deleted my thing, where do you open the autosave backups?

wait why can I not load any file under the autosave section

what's that

I will google later

but how do you recover blueprints?

I mean there are the autosave files?

how do I load it

and if you don't have it?

[icy dragon]

Install one.

[obtuse herald]

you can move the file from autosaves back to you content folder

make sure it's in the same place as before

then reload the editor

[alpine lotus]

it says

[icy dragon]

It's very tedious though.

[alpine lotus]

oh same place

[obtuse herald]

not like that

[obtuse herald]

better than loosing it

[icy dragon]

No thanks
I'd rather take GitHub source control over Unreal's wonky autosave system.

[obtuse herald]

use widnows explorer to move it

[alpine lotus]

where do I move it to?

[obtuse herald]

yeah no thats not what i meant

i mean right now

[alpine lotus]

woops wrong reply

[icy dragon]

Even then I disable autosaving completely lmao

[alpine lotus]

where do i move it to?

[obtuse herald]

hallway > content > <Path where it was>

[alpine lotus]

kk

what

why is the last save like 4hrs ago

when it saves every few mins

ugh

oh well

better than nothing

ima redo everything later

hopefully everything should work after I do tho

I think I know how to do it now

[trim matrix]

Sorry guys, for asking this so persistently, i see you have your hands full but i just don't know where to look for the problem solution. is it blueprints, is it engine, is it bug - i don't know. Before connecting this logic, actor appears in the game and behaves as it should, wherever i connect this logic to event begin play, actor appears in the level and behaves as it should, once i disconnect the logic - mesh dissapears in the game.

here's how i know that only mesh dissapears. particles still play.

this is how scene hierarchy is set. i don't have any other functionality anywhere.

@trim matrixoh u mean what that sequences do?!

[obtuse herald]

'Destroy Actor (Self)'

[obtuse herald]

idk why does it disappear? :p

[trim matrix]

yeah but whenever i restart the game

doesn't all those actor states restart?

yeah i delete it when player touches it in game.

but after restart it still should appear right?!

did the delay, mesh just jumps into existence

@trim matrix where are you from?

[trim matrix]

What does that have to do with my problem?

[trim matrix]

Just Delete your whole project and recreate it, simple

[obtuse herald]

probably becuase of that

[trim matrix]

I already recreated blueprint, same problem is being created. I don't see any point in recreating whole project.

[trim matrix]

Contact the owner of Unreal Engine, simple

[obtuse herald]

you're lerping the size to 0;0;10

[trim matrix]

yeah it's not the prettiest way of doing things but it does the job.

😄

but after disconnecting, shouldn't everything be like it was before connecting?

[obtuse herald]

print your base scale

[trim matrix]

it sets from 0 to 1 that's the problem

but how did the code changed default of the mesh

is that even possible? it isn't constructor code.

[obtuse herald]

the code didn't, you probably did

[trim matrix]

nope

i recreated same problem several times

it happens exactly the same

i put in actor in scene with no logic on it - it shows up - i add logic - it shows up with logic behaviour

i remove logic and - poof

[obtuse herald]

oh wait, you're getting your actor scale but only setting the mesh scale

[trim matrix]

yeah

no scene is

[obtuse herald]

show me this timeline

[trim matrix]

all that logic does is basically this

timeline is simple going from 0 to 1 and back to 0

it's set on autoplay and loop

[icy dragon]

I do a dash and my character goes under the ground
instead of going in a straight line

[sand shore]

you can't scale it down to 0 on an axis and expect it to render properly

[prisma stag]

Quick Question. Is it better to do a pure cast or do a get class and = to, to check if the actor is of <blank>?

[trim matrix]

@sand shore but why it's scaled down when i disconnect the logic?

[sand shore]

Dunno

[trim matrix]

@sand shore yup that's my problem. code itself behaves as it's shown in video. the moment i disconnect it, mesh dissapears - scales down to 0,0,0.

[sand shore]

Try setting the scale to 1,1,1 on end play??

[trim matrix]

still starts with 0,0,0... almost getting convinced i discovered a bug.

[worldly gyro]

he go backward btw

how dude

you save me or what

[shadow saddle]

is there a way to not let my camera go thru the floor like what im seeing right now

[obtuse herald]

Spring arm

[shadow saddle]

which part of spring arm setting

[obtuse herald]

I'll try to replicate it

[trim matrix]

thank you

[worldly gyro]

that make a lot of difference !

[trim matrix]

or i'm loosing my mind here

[honest knot]

Hey guys, I have a question regarding collision.I am spawning a mesh and changing its position at runtime. Overlap Events do not trigger on stationary pawns. is there a workaround for that?

[shadow saddle]

ah ok

[trim matrix]

@obtuse heraldtried doing with the pawn, same thing happens as with actors.

[shadow saddle]

can u guide me more on this im kinda confused

[obtuse herald]

replicated

turn off autoplay

[shadow saddle]

tq

[trim matrix]

where is it located?

[trim matrix]

thank you!

spent good half a day on it

[trim matrix]

thank you!

spent hours solving it.

[obtuse herald]

I can imagine

[trim matrix]

so timeline was continuing play from previous session if i gather correctly?

[obtuse herald]

no, probably playing the first "frame"

[shadow saddle]

ok understood tq

[obtuse herald]

which is setting your scale to 0

I guess it's useful for settings things up to be used later

[trim matrix]

oh i see, thank you again. i spent whole day trying to solve why i couldn't move objects once i understood how to move them, then this problem appeared but i was still continuing to try and fix movement code, when in reality problem was this, preventing any other movement.

[obtuse herald]

is your speed high enough?

[upbeat goblet]

Oh that was it haha, thanks

[royal kraken]

Hey, I am trying to add a widget to my scene, I have got this layout but when I add it to my scene (displayed by a billboard) the icons are not where I expect them, maybe I am doing something wrong with the anchors. And it sometimes cuts off the widgets

[obtuse herald]

displayed by a billboard?

[severe turret]

presumably trying to make it always face the camera in the world. Seems like a lazy way to do it with caveats instead of hooking it up to a component attached to the camera.

but I guess there is a reason for that

[obtuse herald]

but how is he doing that with an widget?

[worn nebula]

How can I add more to a map? I need a inrange to add to a key, but if i have two Adds it only uses the first one and ignores the second

[severe turret]

@obtuse herald maybe attached to the billboard as a 3d widget component. I dunno. It's obviously a confused situation for requirement here.

[royal kraken]

reason is I am not good at UE4. its all still new to me. should I be setting the canvas to 1920x1080 if my game is at that size

[obtuse herald]

that will scale automatically

[severe turret]

@royal kraken it doesn't matter what you set it to. UMG is DPI aware. You need to just use the anchors correctly.

[tropic pagoda]

Hi Guys, Quick Question: Any Idea How i can create an editor script which will generate animation montages from the directory of animations and add few notifies in them?

[severe turret]

@tropic pagoda with a heavy chunk of C++. Try that channel

But dont expect much help there. It's not as simple as "here is the code"

[tropic pagoda]

lol i agree. any ways in blueprint?

[severe turret]

no

[high ocean]

Hey, any other way to clear an array within a struct?
This doesn't seem to work for some reason

[severe turret]

@high ocean Set Member In Struct and null it

[strong solar]

On tick, optimisation wise, how bad is locking something behind a bool, vs for example having a retriggerable delay or timeline playing (or some other alternative that still ticks)? Hopefully the question is clear

[boreal tundra]

how do I change a blueprint from an actor to gamemode base

[high ocean]

@severe turretUhm... sorry but idk what is/you mean by "null it" 😕

[royal kraken]

my understanding of anchors are you select you buttons for example then click align to the bottom if you want them to appear that distance off the bottom of the screen, but these are now screen based so not sure how that works really

[severe turret]

means to create a null reference.

[high ocean]

🤦‍♂️ I still don't get it - sry 😐

[severe turret]

Then I would probably google it, they might explain it better than I

[obtuse herald]

The make array should be null aswell tho

[high ocean]

That's what I don't understand, I'm virtually setting the damn thing to an empty array@obtuse herald

[severe turret]

@royal kraken Anchors can be affected by nested widgets so it's not a simple as "I want this to be here". Often you have to factor in what else is in the way, or anchored between. But it doesn't come across as simple so I understand your confusion. I would go get some documentation for it. It's probably better explained.

[royal kraken]

Ok cheers, Ill look into this more. It would be great if I could anchor all buttons to one of them so i will test it

[wind sequoia]

hey marc

[severe turret]

you can. its just a bunch of containers essentially.

hey

[boreal tundra]

I don't understand, it open visual studio but how do I change

[obtuse herald]

It works for me, so your problem is probably somewhere else

[high ocean]

@obtuse heraldMakes sense, it's kind of what I wanted to investigate - thanks. The problem must be somewhere else

[faint pasture]

Pretty much negligible, depending. About how often is the booll going to be true versus false?

[obtuse herald]

Pardon

try prinitng the bool

[faint pasture]

Have you debug to make sure it's not always returning true or always returning false for the crit bool

[severe turret]

@upbeat goblet you are in a world of trouble already

[obtuse herald]

don't forget that you have a random chance

[severe turret]

that is gonna be so problematic for you

[dawn gazelle]

Your issue is because you're calling the random pure node twice with your boolean.

[upbeat goblet]

Why is that?

[dawn gazelle]

This will cause the Random Float in Range to be called twice.

[upbeat goblet]

Basically I've got a 2D enemy, and I want him to move a bit, then move back so essentially he just patrols back and forth

[severe turret]

@upbeat goblet 1. you are using tick in a non-performant way. 2. you are using a delay in a tick. Which is like smashing a nuclear bomb with hammer

[upbeat goblet]

Oh, well is there any other way to go about doing this?

[severe turret]

yes

[dawn gazelle]

Exactly.

[limber jacinth]

[mossy herald]

when a spell hits the death trigger, it activates and kills the player. How can I fix this?

[dawn gazelle]

Your logic currently doesn't check what is overlapping - you are simply getting the player character and proceeding as if they are the ones overlapping. The "Other Actor" pin on the event gives you a reference to what triggered the overlap - if you plug that into your cast node instead, then only when the player overlaps with it will the player be killed.

[faint pasture]

Why would you ever want a delay in your tick event?

[severe turret]

@faint pasture thats a superfluous question to someone who does it. They don't understand so no point asking them why

[mossy herald]

I understand, quite simple actually. Thank you

[plucky juniper]

Hello fellow gamedevs. What it best practice when it comes to saveGame? I want to save an inventory, can i save a reference actor or do I need to assign an id (guid) to the actor in order to know which one I'm looking for?

[faint pasture]

Make a variable called destination.
Set it every X seconds using a timer or a delay the loops back in on itself

Then in tick, move towards destination

Basically you will be replicating the floating pawn movement, but making this would actually be a very good learning experience.

So to reiterate, on tick, all you do is update the things that need to be updated every frame, that is, movement.

Setting the destination is something that only has to happen every X seconds, you would do that separately. Easiest way would be to have a bit of logic the selects a random location, that you trigger at begin play and then go into a delay the loops back into the bit of logic

@upbeat goblet makes sense?

[boreal tundra]

do gamemode bases need to be spawned to run?

because my blueprint isn't outputting anything for some reason

[icy dragon]

Game Mode should be "spawned" when a level started

[boreal tundra]

do I have to do it manually or is it automatically spawned

[dawn gazelle]

You set what game mode you use in the world settings.

[boreal tundra]

is there a way to use multiple at a time

[severe turret]

no

[dawn gazelle]

No. Only one game mode at a time.

[boreal tundra]

what should I change my second gamemode to than

I want it to be there at all time

[severe turret]

I dont understand that question. What are you trying to acheive?

[spark steppe]

you could inherit the "master" game mode class/bp

[boreal tundra]

I want to have a separate blueprint that defines ammo types and quantities and I want it to be running at all time, so I don't have to spawn it like an actor

[sand shore]

not typically the responsibility of the mode... but you could componetize this and then have a concept of components on your game mode

game modes are, after all, server-only actors

[spark steppe]

or you make it an separate bp which inherits uobject and just holds the data, and add that as a variable to your current game mode

[sand shore]

my suggestion is a bit better because of Get Component/Find Component

You don't even have to cast from Get Game Mode

[spark steppe]

ok, wasn't sure if the game mode supports components

[sand shore]

its an actor

I wouldn't give it scene components, that might not work

AInfo does some sketchy stuff with transform functions

[mossy herald]

sorry to bother you. This fixes the death trigger box but it doesn't fix my checkpoint trigger box.

[unborn maple]

so what the easiest way for devs to start with blueprint programming? i try to get in to shooters gnre but it seem to take a lot out of me for all the different dev in heree?

are platformer the easiest to make?

[faint pasture]

If you're new, just don't even think of doing multiplayer

Otherwise a shooter is fine

[dawn gazelle]

Logic issue again. You are performing operations before knowing what it is that is overlapping. Move your cast to before the very first branch.

[unborn maple]

yeah it wasnt gonna be multiplayer it was goin to be more like socom

military single player base tho

[boreal tundra]

how do I do that 🙂

[spark steppe]

create an actor component which holds your "gamerules" for ammo and such, then add that component to your actual game mode

https://docs.unrealengine.com/en-US/ProgrammingAndScripting/ProgrammingWithCPP/UnrealArchitecture/Actors/Components/index.html

[boreal tundra]

do I add a child actor in gamemode

[spark steppe]

no

once you created a actor component blueprint, it's available on the list when you add new components to an actor/gamemode

[mossy herald]

ok I will try not to make this mistake again, thank you ❤️

[boreal tundra]

?

[spark steppe]

that's a variable

top left the green button "add component"

[boreal tundra]

what should the component me??

[spark steppe]

the one you created

first you have to create it, make a new blueprint and chose actor component as parent class

[boreal tundra]

I do have it

and it is an actor

[spark steppe]

oO it has to be an actor component

[boreal tundra]

can I change it now?

[spark steppe]

maybe, open the blueprint, select class settings from the top menu and in the details try to change the parent class to actor component

[boreal tundra]

I don't have that option

[spark steppe]

which option

[boreal tundra]

actor compnent

I can't change it to that

in the parent class drop menu

[boreal tundra]

?

[spark steppe]

well, then you have to redo it with the correct parent class

[opal ivy]

Is tick rate in unreal 60Hz?

[severe turret]

no

[spark steppe]

your framerate is the tickrate

[icy dragon]

Depends on framerate.
It's not like Doom with fixed 35 Hz tic rate

[severe turret]

120 is the default

but its also averaged to a desired framerate

[opal ivy]

Physics tick rate is tied to framerate?

[icy dragon]

Yes, unless you use substepping.

[severe turret]

physics tick has different tick groups.

[spark steppe]

but it still ticks at the same rate

[severe turret]

it can be variant across all tick groups tho

[willow cedar]

I am getting a issue where when I launch my game and select the level, it spawns me in as a no clip spectator instead of my PlayerBP, but it works for the editor. Any idea why this may be?

[opal ivy]

Okay. So, where would I get started learning how to handle events in the background over multiple ticks?

[spark steppe]

like multithreading or just delaying work of the main thread over several ticks?

[icy dragon]

Perhaps your GameMode have no definition on it or you have no pawns to be auto possessed upon cold loading the map.

[willow cedar]

Ooo, I thought the Pawns would just be spawned off the Game Start

[opal ivy]

I have a task that will task a while (running in the main loop it takes about 1200ms currently) that I want to be able to run in the background

[spark steppe]

is it still your heightmap interpretation?

[opal ivy]

Yep

[willow cedar]

I do have the default pawn set correctly here

[spark steppe]

then the easiest way is to only handle a bunch, and remove them from the array once they are handled

and repeat that task until the array is empty

[opal ivy]

Right, that's fine for the initial load. But at 1200ms to build a chunk, that's going to be problematic for runtime changes to chunks

[icy dragon]

Perhaps your level overriding it with the wrong game mode.

[willow cedar]

How could I go about finding that out?

Actually, I may of found it

In project settings I believe

No, its set correctly, so it has to be the level

[opal ivy]

My goal is to be able to regenerate a chunk at runtime (using a second set of invisible instances until the building is done, then swap the visibility, then clear the old instances)

[spark steppe]

there's not much different on runtime, you populate a list of what changed and only work off what you can handle within the timeframe

or you work with real multi threading, and generate your new chunk in the background before handing it over to the main thread to swap it

but i guess that's something that would require c++

[opal ivy]

Not surprising.

I'm super disappointed to find out how much of the engine requires C++ to use at all.

[royal kraken]

Does anyone know how to change widget size so they are the same size in game if you are close or far away from them?

[spark steppe]

and i'm surprised of how much it can do without c++ 😄

[dawn goblet]

I'm making progress, and I know ABSOLUTEL NO C languages at all

It was that very reason I chose UE over Unity

[opal ivy]

I just really dislike C++

C# is actually my favorite.

[spark steppe]

then you should probably better go with unity?! while some people say that working with ue c++ kinda reminds them of c#

[opal ivy]

I need to learn it anyways, I guess.

apparently a decent free JSON plugin is needed.

[spark steppe]

https://www.unrealengine.com/marketplace/en-US/product/json-blueprint

[opal ivy]

Maybe I can hash out a simple reusable multithreading one too

[willow cedar]

So I fixed my problem, but now the Viewport movement feels different from the Standalone movement, even though they are the same exact Pawn

[opal ivy]

That thing has ZERO documentation.

And I poked at it for a while before I switched to data tables

[severe turret]

VARest is fine for me

[spark steppe]

its pretty much based on https://docs.unrealengine.com/en-US/API/Runtime/Json/Dom/index.html

so that's the docs 😛

[smoky socket]

Hey guys, how can I make the same setup in an Editor Utility Widget? The problem is that I can't make a component reference to a Skeletal Mesh Asset from the Content Browser. Is there a way to get the location of a bone of a Skeletal Mesh Asset in an Editor Utility Widget? If I try to drag the asset from the content browser to the blueprint it says: "Cannot create components from assets in a non-Actor blueprint"

[opal sinew]

I have this delay which is causing problems for some reason.
This snippet is part of a burst fire function, without this delay the gun shoots a 3 round burst just fine
But if I add this in then the gun shoots a 10+ round burst
Any ideas?
