Drag Return Value of GetPlayerController

And search

[queen yew]

wow thank you so much🙏🙏🙏

i have another question.
i am trying to add mouse control for camera movement around a ball that you control with the mouse keys.

i used action mapping to set the events

but it is not working

moving the mouse does nothing when i hit play

did i somehow set it up wrong?

[odd ember]

you're moving the pawn, not your ball actor

if they're not the same, there won't be any movement

this is one of those instances where having GetPlayerPawn globally accessible is really detrimental

[queen yew]

so how would i go about referencing my ball actor?

[odd ember]

you have to go through the motions of understanding blueprint communication

your ballactor needs to be a pawn

your player controller needs to possess the pawn

[maiden wadi]

Usually you'll have two skeletal meshes on a FPS character. One is the third person mesh, the other is the arms. You set the Owner visibility on them differently so that only owner sees the arms.

[spark steppe]

3 meshes, you forgot the party hat

[maiden wadi]

Can't forget the party hat. 😄

[vital fractal]

Also I know a good bit of code but I love blueprints

it keeps my mental status in place

code drives me completely insane

[tawdry surge]

@maiden wadi making a totally separate actor for the camera, setting view and moving the actor around worked!
Mildly confused about the rotation though. A value of one added to the rotation seems to be almost 180 degrees.
At first I thought radians but then 3.14 would be 180.
What is the unit scale unreal uses for rotators?

[maiden wadi]

Depends on the orientation.

Yaw and Roll are both -180 to 180. 360 degrees. Pitch is always -90 to 90. 180 degrees.

[maiden wadi]

Out of curiosity. Where are you adding one? I can't think of a place where that would cause a rotator to do a 180 besides in a normalized direction vector before you convert it to a rotator.

Well. There is one place. If you're at 89.99999 pitch and add one, your yaw will invert.

[tawdry surge]

Getting world rotation, breaking the struct, adding 1 to the z axis, and making a new rotator.
Then I use a lerp off a time line to transition from one to the other

It turns smooth, and in a consistent proportion. Its just not the value system I expected

[maiden wadi]

It will change from 180 to -179 if you add one to 180, if that's what you mean?

[tawdry surge]

It also turns 40-45 degrees if I put in .25

If it was taking degrees as the value .25 or 1 wouldn't move it at all really, if it was radians it would take 6.28 to go full circle
At the moment it's looking like a value of 2.15 or so is gonna do it

[maiden wadi]

That's definitely not normal. Would have to see the logic to comment though.

[maiden wadi]

Ah. that might be why. I didn't catch that Lerp at first.

Pretend you have four frames. So your alpha from the timeline will be 0.25, 0.5, 0.27 and 1.
You start at 0 Yaw. Your alpha comes in at 0.25. 0 yaw lerped to 1 yaw here is 0.25 yaw.
Next frame you start at 0.25, add one, lerp from 0.25 to 1.25. Alpha is 0.5 so you're adding lerping to 0.75.
Next frame is 0.75 alpha. You're now at 0.75 yaw. You add 1 to lerp from 0.75 to 1.75. Alpha is 0.75, so now you're at 1.5
Last frame comes in and lerps you from 1.5 to 2.5 with 1 alpha. Now you're at 2.5

[mild kestrel]

Is there a way to add widgets to screen, not player controller?

[maiden wadi]

To LinearInterpolate correctly, you need to save your start and end location first. These should be stable. Or at least your start should be stable usually.

[maiden wadi]

Create it and call AddToViewport on the return value. It doesn't matter where you create it usually. There are best places for it but that is a long and opinionated conversation. 😄

[tawdry surge]

Oh I got you.. it's pulling new rotation start each frame

So it is supposed to be radians

[maiden wadi]

Rotators are always in degrees.

[tawdry surge]

I'll have to play with it

[maiden wadi]

It takes 180 value to turn and face the other direction. 360 value to turn in a full circle.

[vital fractal]

Hey, I followed this tutorial: https://www.youtube.com/watch?v=dKkssm6D4RU

But now I can just see the pellets of the client and when I shoot from the server the client doesn't see anything

😢

[tawdry surge]

Yeah I know how degrees work, it just seemed like even with a moving start location, adding a fraction of a degree each frame shouldn't have gotten me almost 180 degrees around

[mild kestrel]

yeah but this way it still needs a owner player controller while creating widget

And there's the problem

I want to add a widget first frame the client comes to server world (loading screen of some sorts)

But it does add it after player controller is initialised, so I have a split second without the loading screen, and I am wondering if there's a way to avoid that

[maiden wadi]

Normally it might not. But consider that your code is framerate dependent. You would need to multiply your +1 by the current frame's deltatime. So actually your timeline could move something 3 degrees, or 200, if it's only running for one second.

[mild kestrel]

Here you can see the problem

I Host the game- widget initialises first frame

I come in as a client, i have quite a few ticks without the loading screen

[tawdry surge]

I got you

[maiden wadi]

You normally do this by adding the loading screen to screen before calling open level. I personally do this with a GameInstance Subsystem. Can do the same thing in the GameInstance. Your open level code can get your game instance. Add the widget to screen, then call open level. Then your HUD most likely would GetGameInstance and remove that widget from screen on Beginplay or whenever you're ready.

Also if you're C++ inclined, there's a very nice way to do it in one of the epic examples for the Action RPG. Also makes the screen run on a separate thread so as not to lag as much.

[mild kestrel]

Wait, don't widgets disappear after coming to another level?

[mild kestrel]

I know only basics of C++, and I get soooo confused after trying to do anything in UE4 lmao

[maiden wadi]

Hmm. They might from a hard load.

[mild kestrel]

Because what I'm doing is add loading screen with fade in before changing the level, and then after I add it on begin play of the player controller and fade out

[mild kestrel]

Can I open a level without discarding widgets?

[maiden wadi]

Not sure. I know that ServerTravel doesn't discard them.

That requires level streaming though. and even then you still have to hard load some maps.

[mild kestrel]

dang, thanks anyway, I will look for something else, thanks!

[maiden wadi]

If you're at all C++ inclined. I'd seriously give the Action RPG a look at. Memory says it was even in a plugin. Could be easily drag dropped into your own project and used.

[obtuse herald]

What I usually do is I create a transition level that automatically adds the widget to screen

The transition level then loads the actual level via LoadLevelInstance and removes the loading screen when it's done

But the cpp way is better

Because game modes and stuff

[mild kestrel]

hmmmmmm, makes sense

Will try it later!

[mild beacon]

Why my loading screen is not working? It shows widget for a sec or two and then it turns black untill level is loaded

[dark crow]

Cause that's not how you do it

[mild beacon]

All tutorials on yt told me that lol

[dark crow]

Then they're wrong

[obtuse herald]

They're wrong

[dark crow]

You can handle persistent stuff through levels in the GameInstance

Like a loading screen

[obtuse herald]

Open level destroys semi-everything

Then loads the new level

[dark crow]

It doesn't even fire the next exec node iirc ^

[mild beacon]

uh

[obtuse herald]

Except when it is in the game instance

But the target is invalid then

[mild beacon]

can I do loading screen trough game instance?

[obtuse herald]

Yeah

[dark crow]

That's where you would do it

[obtuse herald]

But still not like that

[mild beacon]

So I do in loading screen map beginplay I trigger custom event in instance?

[obtuse herald]

I don't think I've understand that

Rephrase please

[mild beacon]

So game instance don't have beginplay function right? So I need to trigger event in game instance. I was whitnking, then in loadinglevel map, in maps Bp i can triger that event from beginplay. @obtuse herald

[dark crow]

It's called Init

In GI

[obtuse herald]

Yeah

[mild beacon]

ah

[obtuse herald]

It will fire as soon as the game starts

[mild beacon]

so like this?

[dark crow]

Looks redundant af

Basically useless

[obtuse herald]

Like I said, this still won't work, because open level destroys the widget

[mild beacon]

ugh

[obtuse herald]

Meaning you would be stuck at a freezed screen

[mild beacon]

So i need to use Level Streaming?

[obtuse herald]

Yeah

[mild beacon]

uh

[obtuse herald]

I wonder if asset loading would load the whole map so open level woudn't take up any time...

[jaunty solstice]

I have an array of vertices. I need to somehow sort these vertices by their Y component.
Can anyone suggest how this might be accomplished?

[tidal marlin]

Hello

Does execute command work in release?

[worthy frost]

@mild beacon Look at the plugins, there is one called LoadingScreen

[mild beacon]

Thank you, but I fallowed leavel streaming tutorial and kind of figure it out

[maiden wadi]

You can use non freezing loading screens even during OpenLevel. Just requires some very minor C++ work usually because you have the get the MoviePlayer and use it. It runs on a separate thread that isn't blocked by loading.

[candid zinc]

Does anyone happen to know how to disable the default PlayerController "click and drag to move camera around" logic? setting input mode to UI Only isn't an option for me as I need click events (which need Game and UI or just Game input modes, but that allows the drag to view thing). I suppose I could just set a view target to a static camera and be done with it...

ah, just making a default pawn (that isn't DefaultPawn lol) works.

[humble flame]

Hello, I want to implement a simple system to play a sound when my character walks, I've seen the most common implementation is to use animation notifies and then line trace down to see the type of physical material and play the appropriate sound, however, I was wondering if there's a better solution like doing line traces on each foot on Tick and keeping track of the distance to the ground to see if a sound should be played.

I don't want to put the notifies in each walk animation considering it's going to be too many for each character in the game.

[icy dragon]

Anim notifies would be more easy on performance, as you'd only concerned on playing the footstep sound without branching every frame. Doing line traces each foot on Tick would be the worst way to do it.

[maiden wadi]

I think this really depends on your game. If you're going to have like 20-30 characters max, you could easily program it on tick and disable said thing based on relevancy. Would save the time of setting up anim notifies. This would be very easy with a single skeleton. Traces and vector math are extremely cheap even in blueprint. Though there is something to be said for the hand made setting of the notifies. They're easier on performance, and a lot easier to rely on. And realistically you're not looking at more than a couple dozen animations to do this on as a solo dev. Just the ones with leg movement.

[quick lance]

I'm trying to set up a frontal damage block for an actor. Right now I'm using a collider that will add pawns/actors that are owned by pawns it overlaps with to an array to ignore damage from. Is there a better way to do this?

[lapis saddle]

is there an auto sort? i thought shift d was key but no.

[dawn gazelle]

Did you try undo? Ctrl+z?

[bright frigate]

So this will basically spam lots of sounds for when moving a door. What I'd like to do is play a sound (e.g. creaking) while the door is rotating, but not be spammed like this is. So should I be doing something like checking if lastPosition != currentPosition => Play Sound?

[quick lance]

maybe set a bool (or use a function that may already exist) to see if the sound is playing, and if it's not, play it again.

[bright frigate]

it plays if I move the door as is, but since it's on tick, it's spamming it so I actually want it to stop being so frequent because it saturates all the available sounds

essentially it should be 1 sound instead of many and it should play through the sound if the door is moving. Right now it plays the same sound separately

[quick lance]

then use a do once node or a bool

you can also try PlaySoundAttached or something like that so its on the door specifically

[eternal drum]

Anyone know how to make collision less buggy? (no glitching through, jumping ontop of things)

[bright frigate]

I used an actor location since the door's location is the pivot point. Is that okay?

[light token]

Hello. I have a question. I followed to following:
https://answers.unrealengine.com/questions/519968/bp-equivalent-for-if-ue-build-shipping.html?sort=oldest
I created a cpp class with the content written out in the answer of the website. I already built it for win64. Now when I try to use the node in blueprints it isn't available. How do I make a CPP class available in Blueprints?

[burnt citrus]

Hey I have a question
I wanna make First person and Third person Shooter game (switchable camera)
Then, How to sync ejection and firing effects between First person Gun mesh and Third person Gun mesh?
I don't want to use True FPS style because it breaks some animations

[bright harbor]

so, i am trying to make a system where you can select from multiple characters, each with their own abilities, that all interact with certain objects in the same way. I need an easy way to duplicate characters, as many of the objects rely on casting to the original character to verify that it's the player colliding, so how would i duplicate the player in a way that won't effect these objects, or effect the references in the Animation Blueprint?

[fiery glen]

show your header

(you can paste it in #cpp if you want instead)

[light token]

#pragma once

#include "CoreMinimal.h"
#include "Kismet/BlueprintFunctionLibrary.h"
#include "GetBuildConfiguration.generated.h"

};

@fiery glen

[fiery glen]

oh, you already asked in cpp

[light token]

Yes I noticed that channel after I asked here

But it's a bit of a question for both

since my blueprint node isn't showing up in UE4

Now it is

Thanks a lot!

[fiery glen]

what changed?

[fiery glen]

you could have a base class they all share?

I do not think I understand what duplicate means in this context

[bright harbor]

i want multiple character bp's, who all share the same code and can be referenced by the same cast node

[fiery glen]

I think you want their base behavior defined in something they all inherit from

[light token]

I built it with UE4 closed

[fiery glen]

hot reloading?

that explains it lol

[light token]

hehe it was my first time using CPP with UE4 so I was kind of confused

[fiery glen]

why not do something like having a ABaseCharacter with the interaction code/animbp?

and the different class all inherit from that?

[bright harbor]

I just tried it, and it worked perfectly!! Thank you!! I have legit been trying to figure this out for hours, and i couldn't decipher how i was gonna wire it up

[trim matrix]

hey guys

anybody know why my character isnt showing up

?

[dusk cave]

How do I use multiple condtions on one line trace?

My Blueprint is not detecting the Ammo tag because I don't know where to branch that one node

[dusk cave]

Thanks 🙂

[tawdry mural]

will only check if only theres no hazard

[dusk cave]

Another question: Since I'm using raytracing to detect hits, my variables like health or ammo will go up or down super quick as long as my player is touching the objects. Is there a way to slow it down?

Or delay the hit detection?

[tawdry mural]

well

delay node might work 😄

or you can put a do_once node when raytace hits the target

and open it again whenever you want

for example when ray trace is no longer hitting the target

[dusk cave]

I tried using the delay node by putting it at the end of all my nodes but it didnt work

[tawdry mural]

you have to put it b4 the node that does damage

or adds ammo

[dusk cave]

oh ok i see

I put the duration for 10 seconds and it is slower but it's not 10 seconds between when I print the string

probably because of the raytracing and how it works

oh wait

[tawdry mural]

oh yea it will do the damage after the delay

so no good

[dusk cave]

yea

eh ill use it

[tawdry mural]

try do once

[dusk cave]

ok

what do i attach to reset and start closed?

[tawdry mural]

put delay at the end of nodes and hook it up to reset

smth like that

[dusk cave]

It didn't work

I'm gonna try something

[tawdry mural]

like this i think

2 doonce and 2 delays

[dusk cave]

actually i think i got it

[tawdry mural]

arrows showing where doonce should be

[dusk cave]

yea i moved the do once also

lemme see if I can just use one tho

[scenic scroll]

why is this not working for some players?

it doesn't get the HUD of the player correctly therefore it doesn't work

despite the player clearly having a HUD

this only happens for the listen server clients

not for the server

[dusk cave]

@tawdry mural I moved the do once after the first branch and it works how I want it to. Thanks for the help.

[glass crypt]

How would I separate the physics of a helicopter with the rope that drops from it? The rope doesn't affect the heli until I turn physics on and the heli goes all kinds of crazy.

[earnest tangle]

I guess you'd attach it using a physics constraint? Beyond that it should mostly be a question of tweaking the physics properties of it I guess, but depending on how you want it to behave you might want to forego having it be a physics prop altogether and just manually calculate how it behaves

[crimson hornet]

Does someone has an idea why this interface isnt getting called?

[crimson hornet]

This is in the player controller

[glass crypt]

@earnest tangle physics constraint.. thanks i'll try that.

[crimson hornet]

Im calling this in the gamemode

[exotic latch]

Hello all. Hope you are doing all well. I am glad I found this server and hopefully someone will be able to help me with a question. How can I use a fluid to wrap around an object using blueprint . For example: making a mobile game you can take the fluid and wrap it around your object and it will remain on the object creating a fluid sheald around it.

[vital fractal]

Hey, how do I get the actor that is hit when event hit occurs?

[last abyss]

other = other actor

[vital fractal]

Then why does this not work

[maiden wadi]

Use "Other". Not "Other Comp". Score one for Epic Naming convention fails.

[tidal marlin]

hello. why execute command not work in realize? In standalone all ok.

[spark bridge]

As far as I know exec commands are disabled in released products.

There are much much better ways to set graphic qualities

[maiden wadi]

Unless you're Ark. Then you just release the development build as the final product. 😄

[spark bridge]

https://www.youtube.com/watch?v=rRzbgRgsK1I
check this out

It's not only for Ark. You can always have a dev build on any Unreal game. But you will lose performance gains as a result.

[tidal marlin]

A, ok. Thanks. No option to include the command in the assembly? I don't want to rewrite a lot :))

[spark bridge]

From what I see you are trying to change shadow quality. That can be done by changing stuff by using "game user settings" instead.

[tidal marlin]

Year

But i have a lot code where i use command execute.

If maybe Unreal have enable too add the comand console in realese, its be perfect for only this project.

[spark bridge]

I believe you shouldnt use command consoles at all.

They are as their name implies, overriding values via a console

That a released game should NOT have as an option.

[vital fractal]

Literally what I used

it's weird

[maiden wadi]

That's odd. This isn't server code is it?

[vital fractal]

it's singleplayer code

[maiden wadi]

You are hooking up the execution pins?

[vital fractal]

huh

[maiden wadi]

Blue nodes with the white arrows only run when the left side has a white execution line ran to it.

[vital fractal]

Ohhh

Then uhh

what

What was that little thing

nvm

Oh hell yeah it works

What was that condition block?

this thing what's the name of this thing

[maiden wadi]

Equals.

What are you trying to check?

[vital fractal]

Which one is hit

what type of actor is hit

[maiden wadi]

Ah. Don't use that one. Right now you're asking if one instance of something hit another instance of something.

[vital fractal]

big words

brain boom

[maiden wadi]

Wait til you start in on instantiation, and hierarchy inheritance. Or hierarchy inheritance. Epic still has us all beat with UHierarchicalInstancedStaticMeshComponent though.

[vital fractal]

I just wanted to check whether I hit the cube and disable floor hits since when u hit something it disappearrs

[maiden wadi]

If you want to check if it's a specific cube, use the check you already had. If you want to check if it's A cube, then use what I posted with the Cube's actor class as the Parent Class.

To use what you had, you need to get an instance of the other cube you want to check against though.

[vital fractal]

YES but whats the name of this

like equals but what specific equals

[maiden wadi]

Object

[vital fractal]

How do I power the branch when another branch is powered

By the event

[maiden wadi]

Put them in line. Depends on how you want your logic to go.

[vital fractal]

in line?

Ohhh

I think I get it

But

Directions are not complete

like

[maiden wadi]

You can sequence it if you always want both of those to run.

[formal wren]

Is it possible to enable / disable Groom Hair simulation at runtime? Cant find a way...

[past spoke]

hey guys

anybody know why character is duplicating

I set it to use the character on play

[tawdry mural]

it creates a character and the one you put in manually stays

[gilded pebble]

what would be the best way to bulk edit a BP's component transforms?

like multiply all X in location with 2, even though the X is different in each component

[past spoke]

ya i noticed that

if I dont have the character in the scene it will not duplicate

I just find it weird that you start the game with an empty scene

like I mean with no character in sight

[tawdry mural]

use this to set a location where you spawn

[boreal moon]

Hey guys i am working on active ragdoll character ,i want to ask some (a lot of ) questions about CONTROL RIG and Physical Animations ,who can help me?

i cant find any information about UE active ragdoll characters

[fallen glade]

any way to bind move AI when it's done?

[fallen glade]

post in #legacy-physics

[earnest tangle]

what do you mean when it's done? success and fail are when the movement is "done" but with different results

[fallen glade]

yeah whichever is fine I found this but it makes no sense I don't even know which pawn is done moving

[earnest tangle]

What's the target on that?

[fallen glade]

AI controller

[earnest tangle]

Yeah so that's another option for it I guess

if you wanted to get the pawn which finished moving for the event you would probably need to store the ai controller ref so you can get the controlled pawn

[fallen glade]

how would I know whick AIController is done from this though? Doen't make much sense

[earnest tangle]

save the one you bind the event to I guess

it's a bit annoying many of the events don't carry the sending actor as the parameter

[fallen glade]

So like a map of "Pawn" and "event" ?

[earnest tangle]

Oh, I don't know if that's possible

[clear hinge]

When i possess my character by another(a vehicle) his anim BP stops responding and no print strings from it run, any idea? Character switches to T-Pose

[earnest tangle]

this would be easier in C++ since you could bind a lambda to the event or something where you can carry the extra info for it tbh

[fallen glade]

yeah it's not haha

[earnest tangle]

another method would be to move this logic into the AI controller

then you know which one finished

[fallen glade]

True, thank you for your help @earnest tangle ! I'll keep trying and if I don't make it happen I'll put everything into the AI

xoxo

[fallen glade]

I'm stil confused though, how does the engine do this? Can it be done manually in bp?

[obtuse herald]

What, more than one output loop?

Macros can do that

And cpp as well ofc

[fallen glade]

no how to know when pawn is arrived?

or has failed

Trying to combine these nodes

[obtuse herald]

It's probably checking if the pawns location is changing

[earnest tangle]

There is a delegate for it in the ai navigation request which handles it under the hood

[obtuse herald]

If the pawns location is ~Dest then Success

[earnest tangle]

but much of the machinery is not exposed to BP's

[fallen glade]

Right I see

[obtuse herald]

If the pawn doesn't move anymore then failed

[earnest tangle]

this node is the best you can get for it mostly.

[obtuse herald]

But there is probably more to it

Because there are NavProxys or whatever they're called

Basically a "Portal" for the Nav. Where you can decide in bp what to do so the pawn reaches the other side of the proxy)

[fresh charm]

hi

someone can help me how i can desactive this ? (cemra clipping) (same in play)

i try to modify in general setting but not effect

[spark steppe]

did you adjust the near clip plane?

[fallen glade]

that doesn't look like camera clipping as there is no line. maybe I'm blind

[gilded pebble]

what would be the best way to bulk edit a BP's component transforms?
like multiply all X in location with 2, even though the X is different in each component

[fallen glade]

got an example @gilded pebble ?

[gilded pebble]

With editor utility for example

Well for example I have an actor

with 5 different components with different transfroms

I want to multiply the X in the location of all 5 transforms to make them more spread out

[fallen glade]

can get all components by tag then set a random position

[gilded pebble]

Normally I would need to do it one by one, Is there a way to bult multiply them even though it says "Multiply values"

yes, but that only works in Runtime, what I need is to edit the default transform of the components

I tried to use Editor Utility Plugin, but can't seem to get it to edit properties of Blueprint Classes the way it does for example textures

[fallen glade]

sorry never used editor utility thing

[tight schooner]

@gilded pebble you can make a function "run in editor" in the function details panel

And then the function will appear as a button when you have the actor selected in the level editor

[gilded pebble]

Thanks, but that doesn't edit the default values of the class, only the instance

[tight schooner]

Sorry, dunno about editing class defaults programmatically

[fresh charm]

wdym

same ingame

i can't see my body

[spark steppe]

you said you changed something in project settings, close render culling is dependent on the near clip plane

[civic crypt]

I want to slow max speed down when 2 InputAxis are pressed at the same time. I know I need to divide them but I dont know how to create an IF statement in blueprints to achieve that. Anyone have an idea? Im trying to slow diagonal speed basically.

[spark steppe]

when you add velocity to your pawn clamp the vector length

[spark steppe]

you can define functions as call in editor and call them from the actor details panel

they just can't have any arguments, but you could still make a randomize location method

[gentle urchin]

I wonder why it'd be interesting to change class default with an editor widget? What usecase is there ?

[spark steppe]

maybe you want to apply editor changes to the class as default?

[gentle urchin]

What sort of editor changes? Did Loki provide an example? In case there's other ways to achieve it

Oh nvm, reading up.

[spark steppe]

im not sure if he wants to actually change the default value for every instance

i assumed it was more related to instances

[gentle urchin]

I'd think so too by the description

Multiply 5 component transforms location.x by 5...

Guess you could edit "class defaults" by programming variables for it dynamically instead and using those as "defaults"

It wouldnt actually work in editor but in game/as instance it would

Bulk edit would only work if they were of the same parent class tho

Explaining it makes it sound horrible. Wouldn't recommend

[civic crypt]

Thanks for the tip but it didnt really provide the desired results. It did clamp directional speed, for example, when I moved right but I need it to clamp when both inputs are active. So I did pawn > get velocity > vector length (split struct) > clamp vector size into add movement input. I still feel I am missing that IF statement. Clamp IF move forward is active kind of thing.

I also tried character movement component > velocity > vector length > clamp but that just made it do weird things lol

[tight schooner]

@civic crypt Are you using input axis events? I haven't dealt with character movement before personally, but I will say generally that you don't have to use the input axis events to process those axes. So if you're trying to process two input axes in relation to one another, you can do it on Event Tick and use the Get Input Axis nodes (or something like that). Then you can combine the float values into a 2D or 3D vector and clamp the length and stuff, rather than trying to process each axis on their own parallel ticking event.

Also to answer your other question, a Branch node is the practical equivalent of "if" in BP.

[civic crypt]

I know branch is the node but I wasn't sure how to introduce that with floats/vectors. I havent looked into the get axis node. Im not seeing it but I do remember running across it at some point. This is what I have here:

I realize the axis value isnt plugged in for MoveRight, thats cuz I removed it prior to the picture lol

[tight schooner]

yeah I was kind of confused there...

so yeah the point I was trying to make is your two input axis events are just tick events for convenience, and the complication seems to stem from running two parallel tick events but having the two inputs affect each other

so I was saying it makes more sense to do it as a single line of execution

coming out of a single tick event (Event Tick is the obv. choice, but using just one of the Input Axis events is OK too)

and then you just use the Get InputAxis nodes to get the values

and process them however you like into a vector that you feed into Add Movement Input

[civic crypt]

Ya I agree. So is the InputAxis not native because it doesnt show up in my blueprints.

or are you talking about the input functions?

[tight schooner]

you should be able to Get MoveForward

Get MoveRight, etc.

[civic crypt]

ok yes got that haha

I was looking for a float 😆

Thanks for the direction @tight schooner Ill give this a try.

[tight schooner]

I believe what Ben was practically suggesting is you can pack both axes into a Make Vector node and feed that into Clamp Vector Size to limit the total length of the vector

We're assuming you're trying to prevent the classic game thing where the player moves faster at a diagonal

[civic crypt]

indeed lol

Im not super familiar with vectors. Im somewhat blind in this aspect but this give me a lot to research and learn, and thanks for clarifying Ben's suggestion too.

[dusk cave]

hey guys have a noob question here. When I shoot my bullets, they go through my objects. I've tried changing my collision settings but nothing has worked. All my other objects can detect if my character touches it. What am I missing?

[gilded pebble]

That only sets the transform of the actor's components, not the default for the class

[civic crypt]

@dusk cave Have you given this a try? https://answers.unrealengine.com/questions/57343/view.html

[north marten]

Is there a way to stop a component inside a ball that is rolling, to not roll with the ball? Think of a hamster inside a hamster ball. The "Lock rotation" isn't doing it

[dusk cave]

@civic crypt sorry I think I typed that out wrong. I just need my bullet to work with event hit or I need my other objects to detect if my bullet hits/passes into them.\

I think that link is for if the bullet collides with the character when it spawns

[icy dragon]

Don't attach the component to the ball.

[civic crypt]

There maybe someone here more knowledgably on collision detection than me. That post was about the extent of it haha

[dusk cave]

I'd figure using event ActorBeginOverlap could work but it didnt also

[civic crypt]

@spark steppe @tight schooner I got the vector clamp suggestion to work! Thank you for that. Now I just need to figure out how to reduce backward diagonal speed comparably.... 🤔 lol

[spark steppe]

shouldn't the vector length clamp range just be something like -1 to +1

[civic crypt]

Well it works perfectly. All directions match their set speeds. However, I set backward input to -.8, so moving back works diagonally resets that to the aiming speed. I was hoping that would make the diagonal -.8 as well.

[warm citrus]

Trying to play media on all clients but it's only running on one even though all of these are replicated / multicast

[warm citrus]

if you know anything @ me

[north marten]

How can I get the thing inside the ball to move around with it tho without attaching it?

[late cave]

Is there a way to set an actor label on spawn?

[dawn gazelle]

Widgets aren't replicated. You can't run RPCs from them.

[warm citrus]

So how would I overcome that?

[obtuse herald]

Probably have an actor as wrapper

[dawn gazelle]

You'd have to run the RPC through a different class (perhaps gamestate makes the most sense for this one since it's for all clients) which then would need to call the UI on your clients to perform the required operation.

Check out the multiplayer compendium pinned on the #multiplayer channel.

[warm citrus]

So instead of making it a UI, I just played the video with a keybind, and I used replication, but it still won't work. No idea what happening, still new to multiplayer

This isn't in the widget blueprint, this is in the level blueprint

[dusk cave]

How do I reference my Bullet Actor here

[foggy escarp]

what bp is this?

[dusk cave]

this is inside my enemy blueprint

[foggy escarp]

it makes more since to me to create a event on the bullet bp for this.
On bullet overlap, attempt to cast to the enemy. if it succeeds call the custom event for take damage in the enemy bp. or you could just use the damage node directly in the bullet bp.

[dusk cave]

I just need the bullet to destroy the enemy on overlap or hit

so would i still keep it in my enemy bp or do it in the bullet? Either way, I can't figure out why my EventOverlap node hasn't been working

[solar sequoia]

Is setting a series of variables or a struct after runtime the only way to incorporate data table values into a BP? Like, I can't somehow bind a collection of variables to a data table through the editor, can I?

[chilly swallow]

Hi all. Not sure the best place to ask this... but if I have a sample project that I would like to borrow something from e.g. the way the Spatial Audio is set up in the Spatial Audio Temple project; is the best way to use this logic in a different project to Migrate it? Or some other workflow?

E.g. if I have a plugin for footsteps, a sample project for spatial audio, another project with the assets... should I basically just migrate everything into a master project as one of the first steps?

Thanks

[solar sequoia]

Or maybe can I just call the struct I need every time I need to call a variable? I have no frame of reference for how much more costly that is compared to individual variables

[dawn gazelle]

You can create a variable of the structure type itself and store the value from the data table. If you need to reference only specific variable you can use "break" node to get access to the specific variables.

Otherwise, if you want to store them individually, that's fine too, but you'd have to manually create and set each of the variables after reading the values from the data table.

[solar sequoia]

Cool, that seems to be what I want. Calling the structure frequently won't cause many issues over just using variables individually, would it?

[true valve]

An enum with 3 items not an array can you randomize it

[solar sequoia]

Maybe. Worst case you just do a select node and randomize an integer to select your enumerator

[true valve]

how? The index of select has to be enum

[cinder raven]

Is there a way to get a variable from a spheretraced actor's blueprint into the blueprint doing the tracing?

[solar sequoia]

"random int in range" and then plug it into a select node. Then you plug the select node's output into your enum input and it automatically changes the wildcards to enum of your type

KIM that the first index is zero, so your int range would be 0-2

[solar sequoia]

You're using a select on enum node. Use the one that's just called "select"

[true valve]

I got it thanks

[tight schooner]

Not sure what you mean. If you can cast to it or otherwise interface with it, you can get data and call functions. But AFAIK it has to be initiated by the thing doing the trace

[cinder raven]

I tried getting gameplay tags from the actor being traced and while they were set within the sphere traced actor they could not be read by the actor doing the tracing. I can't cast the blueprint being traced to pull variables from it because I want it to be different depending on whats being traced, is there another way to just start pulling and reading variables without casting?

or a way to cast from what was sphere traced?

I thought gameplay tags would have been the solution but for some reason "Get owned gameplay tags" will not pull into the other actor's blueprint

[dawn gazelle]

Create an interface. The interface should return whatever values you want to return from the actor. In relevant actors, implement the interface and return the values you want to return from the actor through the interface.

It would end up looking something like this:

[cinder raven]

Ok thank you for your help and your time I'm gonna read up on it now

[hard yacht]

How is this function supposed to be used if it has no inputs or outputs?

[dawn gazelle]

My guess would be you place the controller on a flat surface, then use that node to "set" the level.

[fiery glen]

void UKismetInputLibrary::CalibrateTilt()
{
    GEngine->Exec(NULL, TEXT("CALIBRATEMOTION"));
}```

it literally just calls a console command CALIBRATEMOTION

hello

Im trying to make it so that after 7 seconds of idle I want to play a random idle breaker animation

Can anyone help me?

[lament schooner]

Hello. I am new around here, I apologize that English is not my main language. If it is not a suitable channel to ask this, I am sorry. In a multiplayer if for example I have 100 players in the same game, how do I assign a camera / point of view to each one? I can't find any mention in the forum or youtube about this.

[wind sequoia]

#multiplayer

[lament schooner]

Im talking about camera / point of view nothing more and I have used the example of multiplayer and 100 players as an example.

[zealous moth]

@past spoke i wouldve used in the character bp and the play montage node.
Simply have a cobdition that determines if idle. Then after a timer countdown play a montage.
No need to go into the anim bp.

[past spoke]

This seems to work for me

[past spoke]

do you know what this message means

[meager rune]

Having a bit of trouble with input. Recently added a drone that is controlled by the player controller in addition to the player character. After implementing the drone, all movement and mouse input for the player suddenly doesn't work. It still runs the action evens, but the value for axis events is alweays 0.0 even when I move around and look

actually the axis values do work, the "add movement input" node doesnt work now

the code for sure executes, the add movement part doesnt seem to work

I have a character movement component, and it worked fine before adding the drone in (even if the drone is not spawned)

jumping seems to work fine

as well as aim down sights

I may have found the problem

[halcyon hill]

Hey Everyone, I've created a new Blueprint class that I'm calling PowerNumber. It's a number that can hold really really really large numbers by separating out the float Value of the number and the Power/Exponent of the number. It might hold a Value of 2.465 and an Exponent of 453 to represent 2.465E+453.
So this has been working fine, but... the Blueprint approach makes this number an Object. If I use an Int or a Float, it's a value. I can set a default value and use it without initalization. If I use a PowerNumber for a number, it's an empty object slot that has to be filled with an instantiated object at runtime. Is there a way to fix this? Is there a way to make my PowerNumber as versatile and usable as another built-in type like Int or Float. If not with Blueprint, can I do with with C++ ?

[twilit heath]

struct

[halcyon hill]

Structs can't have their own functions though, right? How do I do custom Addition/Multiplication and stuff if I'm using a struct?

I guess I could use a Blueprint Library for the functions that work on the struct maybe?

[static charm]

a struct is a variable you can use almost anywhere once you've created it

also depending on which engine version you're using, there is Double support, so you can store pretty large numbers anyways.

[past spoke]

Can somebody help me, this is my main menu level, but after loading the play level this happens....

the wall, cylinder and the green marble are part of the mainmenu level. everything in the background is the gameplay level. i thought loading a level was supposed to destroy everything??

Nevermind it was loading an instance instead of open level.

[fair magnet]

Can anyone give me an idea for how to move Actors around in runtime just like it is in the level editor ? I already have a Gizmo that I can select I just need some kind of logic to actually set the new location from the mouse cursor.
I tried with "Convert mouse location to world space" but that ends up being offset of the original location and is also way too slow so it doesn't stick with the cursor.

[candid acorn]

Also interested in this logic, haven't tackled the gizmo just stuff yet ;D

[fair magnet]

Yes you can.
Pretty much answered your question yourself :o

Couldn't you just "deactivate" inputs in the animations and "activate" them with that notifiy ?

hmm doing some googling

i think i might have found something for it

ty for the tip

[obtuse herald]

You're welcome

[onyx violet]

after doing some digging, what I'm kind of trying to do is the opposite of a compound interest equation. This equation i'm seeing is taking the base principal, rate and number of times compunded and getting the amount.

Hi, why is my line trace so weird and not in the crosshair?

[icy dragon]

How do you setup your line tracer?

[fiery glen]

motionblur also makes debug lines look funny

r.motionbur.amount 0 can make debug lines less funny looking

[fiery glen]

multiply the forward vector of the camera by a float instead of a vector

[obtuse herald]

At forward vector you probably want to multiply by float instead of by vector

Or multiply every vector component by the same amount

[fiery glen]

right click that sucker

[obtuse herald]

UE5 so cool

[fiery glen]

the ui for changing math pin types is really not nice

[devout dove]

Did it with float and it has the same result..

[fiery glen]

it should just be a button on the node

[icy dragon]

UE5's modular arithmetic nodes are kinda confusing tbh

[fiery glen]

we mean a single float dude

that way it's not getting skewed on the X

[obtuse herald]

You mean smth like when creating a new variable?

[devout dove]

Thanks this fixed my issue

[fiery glen]

sweet

[devout dove]

Any ideas how to make a lock on system?

[fiery glen]

something like a little extra button arrow thingy near the value pin

no idea

it's just weird how it's so hidden

[devout dove]

I guess I would need to get the hit pawn and use it's reference and get his location all time right?

[obtuse herald]

Yeah

I was always deleting and creating a new node while I was testing ue5 xD

[obtuse herald]

Yeah, something along that

[devout dove]

I have a question about a node, i realized it has a weird delay. So when I click, it doesnt shot the line trace, but needs 0.25s to shot it after holding the button.

But i have initial delay set to 0, how can I make it instant shot as soon as the button is pressed?

[maiden wadi]

@devout doveSave a timer handle from the return value. Use it to check if timer is valid. If not, call whatever the red line is calling imediately, then start the timer.

[devout dove]

I don't understand how you mean it exactly

So no custom event?

[obtuse herald]

Call the custom event before set timer

[fiery glen]

call ShotGun right before the Set Timer By Event

[maiden wadi]

Only if ShotGunTimer is not currently active.

[brazen pike]

you could just spam the button that way, negating the point of the timer

[obtuse herald]

Yeah that's true

[devout dove]

Like this?

[obtuse herald]

Yeah, but before you call it check if your timer variable is valid

And only if it's not you do the stuff

[devout dove]

like this?

[obtuse herald]

Yupp

[brazen pike]

or a validated get is a little simpler, combine three nodes to one

but if it works, it works. no need to make it more complicated if you dont have to

[obtuse herald]

The fancy way

[devout dove]

i don't know how to do that

[brazen pike]

right click on the get variable

[devout dove]

Should I create a function for that?

[brazen pike]

then at the bottom

[devout dove]

ok what then

[brazen pike]

it gets the node and checks if it is valid at the same time. You just connect up the pins

so its the same connections you did in the branch

but instead of 3 nodes it's now 1

[devout dove]

Idk what you mean

[brazen pike]

not on the pin, but the node

[maiden wadi]

Pretty sure that's only for hard pointers?

[fiery glen]

yeah I don't think this struct supports a generic boolean operator

[brazen pike]

Ah that sucks

[obtuse herald]

There is also a IsValid

Node

[fiery glen]

here's an example

[devout dove]

But mine is a Timer Handle Structure node

[brazen pike]

You can just leave it, it's not like there'll be any performance drops because of the extra node or two

[fiery glen]

I know, I was showing with an actor reference

sorry for the confusion

[devout dove]

Don't worry, I'm thankful that you all taking time to help me, all I can say is thank you 🙂

Do I need to have this connection here?
I'm trying to wrap this somehow into a function but it's very messy and causing errors

[obtuse herald]

Yep

[devout dove]

Can't I promote it to a variable or something like that?

[obtuse herald]

You can also use a CallEvent node

And then select the event there

Or maybe it's called GetEvent

[devout dove]

like this?

[obtuse herald]

You can also have that red line (called a delegate) as input for your function

[obtuse herald]

Yep

[pseudo narwhal]

Hi, I have my skeletal mesh and I want to use blueprints to rotate one of its bones (like pressing a key and rotating X=30º), but I cant figure it out how to do it

[fiery glen]

you can absolutely still spam shoot with that timer setup? am I wrong?

[pseudo narwhal]

I tried doing it in the animation BP, but doing it inside the animgraph sets the bone rotated all the time

[devout dove]

@fiery glen What do you mean?

[obtuse herald]

Timer invalids after 0.25s, so you could technically double shoot every 0.25s but that's need a pretty good timing

[devout dove]

I just did that -_-

Yep you can shot with that 2x the speed

[obtuse herald]

Oh

[fiery glen]

releasing the mouse always invalidates the timer no matter what

[devout dove]

And I don't know how to fix that

[obtuse herald]

Oh right

[devout dove]

So I need to add a time delay before invalidating it?

[obtuse herald]

Yeah you can totally spam click

[fiery glen]

need another boolean value

[devout dove]

should that work?

No that's bad

[obtuse herald]

Yeah, but use a retriggerable delay

But I'm pretty sure there is a better way

[fiery glen]

make a new boolean called WantsToFire or something

only clear the handle when the time elapses AND you don't want to fire

still feels weird but I can't think of anything better that isn't ticking

also I just drag the red line to the event directly instead of creating a new event

[fiery glen]

which should not really matter here though

[fiery glen]

we are doing automatic weapon fire here I guess

this would work great for a semi auto weapon

[devout dove]

I tried this but also doesn't work 😦

[obtuse herald]

Yeah that perfect actually

[fiery glen]

just copy what I did directly

don't use the extra delay node

[fiery glen]

that's actually somewhat cooler because it lets you set a separate "cooldown"

[devout dove]

It works but it also has a tiny problem, when tripple clicking the delay takes to long and it doesn't shot, then you need to release and click again to shot.

[fiery glen]

but yeah don't let it set multiple delays

[devout dove]

but when i click the button while the delay is on, it wont fire

[fiery glen]

it could still set the weapon ready cooldown multiple times merely by releasing the input

[devout dove]

Works like it should but damn, that's a smart solution to that. Thank you 🙂

This could be done on tick right? Not very efficient but I think that this way it could just skip the delay,

I know a game that works this way, the game uses also Vsync as default so having a 240hz monitor gives you advantages in that game :p

No matter what this is great solution. No matter how fast I click I can't double click. On click tester I did 18clicks/second so I guess that's good

[fiery glen]

UE is designed around a variable ticking rate either way

as in always considering the current delta time

Does anyone know how when linking selected item (string) to a command, i can also add a command, meaning my command + returned selected item string

right now it returns a resolution -----x---- but i want to return r.setres -----x-----

[obtuse herald]

append string

[safe flame]

is that good? @obtuse herald

damn that worked

awesome thanks

[maiden wadi]

Is there any reason you're not setting it through GameUserSettings?

[safe flame]

I am not really sure why i havent, can you explain me what does this change and why its required?

But i will surely do now

i am also having problem with r.fullscreenmode, i also tried print but there was no printing for some reason, and the window type not changing

[obtuse herald]

you're putting your parameters before your actual command

[safe flame]

it should be on B?

I also think that window types are with integers and not names if i am correct

so i could replace the labels

[safe flame]

you have the url for this because i couldnt find it?

[obtuse herald]

http://www.kosmokleaner.de/ownsoft/UE4CVarBrowser.html
this site is probably helpful for you

[safe flame]

youre the best

[safe flame]

I changed to this one but still not changing full screen type

[obtuse herald]

can you print the output before you're running it?

[safe flame]

i tried but doesnt prin anything for some reason

it should print here correcT?

[obtuse herald]

no, at the end

also you have to connect the exec ofc

is it normalized/a direction vector?

[safe flame]

like this?

[obtuse herald]

yeah

what does it print?

[obtuse herald]

seems right

[safe flame]

im launching it now

than clicking play

[obtuse herald]

yeah

[safe flame]

doesnt seem to change anything

[obtuse herald]

apparently the command ain't workin no more

but the setres command can turn it into fullscreen "aswell"

just put an 'f' at the end

[safe flame]

hmmm so what i have to do is to get current resolution and add an "f"

[obtuse herald]

yeah

or you use the functions from game user settings

reaching from -1 to 1

what is your setup?

how do you get the vector?

what rotation do you want?

Ok

Is it a location vector?

or a normal/direction vector?

alright

I'm assuming you want the avg. rotation of these two rotators?

you mean that?

I tried my best

[ionic crescent]

You are all so helpful =)

[obtuse herald]

That??

[safe flame]

@obtuse herald Sorry to bother you, a quick question

in the combo box, there are some array elements

in the click, when returning it gives me the selected string, but can i get the selected element?

as string ofcourse

[obtuse herald]

you mean without the event?

[safe flame]

Here, it returns the selected string

but i want to return the array element, 0-1-3-4-5

[obtuse herald]

ahh

[safe flame]

but what happens with selected item that hasnt returned

[obtuse herald]

wdym?

[safe flame]

i mean, it will work now ? because in the combo box nothing is returned where selected item is

damn it worked yes

Thanks for helping me, trying to understand how blueprints working lol

[obtuse herald]

ah, yeah you don't need to use that

it's bascally a shorutcut for that

[safe flame]

yeah trying to understand how exactly it reutrns something that is not connected with the event, on selection changed

but seems like it takes its action by self

[obtuse herald]

what do you mean by that?

[safe flame]

I mean by doing only that, that is enough than connecting it with the event trigger

[obtuse herald]

Yeah, because you're referencing your combobox again with that blue thing. If you would use some other combobox there (i.e. Fullscreen) then it would get the value from that and set the postproccess based on that

[safe flame]

thats really awesome

i tried getting selected index from returned selected item from the event but couldnt find, so i guess whats what i only have to do

[obtuse herald]

Yeah, selected item is only a string, there is nothing more to it

[safe flame]

yup, some times you need the index to get the values if they are the same, for anti-aliasing, all index elements are fitting with the command when selecting.

I just dont understand why on tutorials they are having 10 buttons for normal, medium, high, every single of it has a button than having a combo box

[surreal peak]

10 buttons is weird, but comboboxes are also garbage

I usually code my own "horizontal combobox" which looks like this:

< CURRENT OPTION >

[safe flame]

Yeah thats damn awesome

i want to learn that too one day, seems better than everything

[surreal peak]

Can be done just in BPs, so nothing is stopping you

[safe flame]

i guess a button for changing the option

[surreal peak]

Yeah the center is a Textblock, the < > are a button each

Internally it's an array and a variable for the current index.

Buttons increase and decrease the index and update the Textblock

[obtuse herald]

same

[surreal peak]

The nice thing about your own widget is that you can make two arrays, one for the friendly name and one for the option

Often the option is some weird English word and the friendly name has to be translatable

[safe flame]

You think there is a tutorial about this one out there? it would be great if someone created one

[surreal peak]

So having two arrays is better

Not sure

[obtuse herald]

You're welcome, just try properly phrasing your question next time

[safe flame]

I will surely do that one tho, i am just messing around for now until i learn blue prints well

I take that as a yes, and what do you get?

[trim matrix]

oh thats because i think it will spam the text

[obtuse herald]

does it print anything at all? do you always get 0?

[tame pasture]

Maybe try 0.1 as duration

[obtuse herald]

0 works on tick

[obtuse herald]

connect delta time x to duration

and check if your cast wokrs

[tame pasture]

❓ Couldn't find a 'Input' channel, so I am just going to ask here: I can only press buttons with Left-Mouse. Is there any way to change that somewhere? Maybe inside the project-settings like the input page?

[tame pasture]

Nah. That input page only handles input created by me. E.g. running, jumping. But a Button Press is a standard. It just works out of the box. But I don't wanna use Left-Mouse

[trim matrix]

Can I have this twice in the same blueprint

[obtuse herald]

Yeah I don't think that's easily possible, the click event gets forwarded from slate afaik.

so you need to override that

[tame pasture]

That's what I thought.

Sadness

Well, guess I have to work around that

[minor folio]

I'm trying to create a simple path/curve editor that I can manipulate in editor mode for objects to follow. Where would I start with that?

[gentle urchin]

Isnt it overrideable in the playercontroller? Default click method in the settings or something?

[trim matrix]

@tame pasture damnnn

[obtuse herald]

Oh

It is

well @tame pasture here you go

(In PlayerController)

[trim matrix]

@tame pasture

here's a screenshot

do you see clearly what im trying to do ?

[tame pasture]

Use a Sequence after "... Update Animation"

[tame pasture]

Wooooow, thank you!

I will try that

[tame pasture]

Sadly doesn't work

I don't know what that setting is for. But if I select 'E' there and press 'E' on my keyboard, no button underneath the cursor will be pressed.

Maybe I am using it wrong.

Did 'K' work on your side? @obtuse herald ?

[obtuse herald]

honestly I didn't try it

[tame pasture]

Oh okay

[obtuse herald]

well a simple tooltip reveals it

what you can try however (a bit hacky but maybe worth a try) is adding a widget component that draws your widgets infront of the players camera

because that IS a component

Ok apparently if you use a widget component there is an extra widget interaction component that handels the input

[tame pasture]

And you can change input settings there?

[obtuse herald]

You need to call a funtion that sends the input, kinda like this

it's used for (mostly vr) game controllers

you probably always want to be able to release the key tho

[tame pasture]

oh wow

How could I forget

I used that when developing VR games

f...

[obtuse herald]

hahaha

[tame pasture]

Thank you

[obtuse herald]

you're welcome

[sonic oak]

Does anyone know how I can access this within a blueprint?
https://docs.unrealengine.com/4.26/en-US/API/Runtime/Engine/Engine/UTexture2D/HasAlphaChannel/

I want to check if a Texture2D has an alpha channel, because I want to apply it a material supporting transparency if it does

[safe flame]

Does anyone know how i can set a text when clicking a button? the text is empty

[turbid rapids]

Hi guys
Can someone help me know how can I make a destructible vehicle?

[safe flame]

Where exactly did you find this? should i do it on button click? because i want this to happen when they click the button but tried to find settext, cant find it

[obtuse herald]

get your text reference

drag the pin

set text

[safe flame]

Unfortunately i have no idea how to get my text reference

[obtuse herald]

You have a text somewhere in your widget that you want to change, right?

Click on it

set 'Is Variable' at top of the details panel to true

[safe flame]

yes this one

[obtuse herald]

that is your hierachy panel

that is the details panel

[safe flame]

awesome yes, i did that

[obtuse herald]

now go into your graph

on the right hand side are the variables

there is also your text variable

[safe flame]

yes, now i can do set text

is it possible to get the text of the button

so i can change the text on the selected test?

i do the same way i guess?

[obtuse herald]

yeah

[safe flame]

okay this is the text i want to transfer to selected chapter text

is that correct?

[obtuse herald]

it is

[safe flame]

awesome thank you

couldnt find anywhere saying how to do it

Yup that worked!

[obtuse herald]

If you have an UI element and it's not inside your variables, just tick that box

[safe flame]

yeah i didnt know that, well i was trying to search about it, i was like where the hell is it and its not in the list

that tick thing fixed it

you're the best, thanks for helping

[maiden wadi]

Next step. Doing it with localization. 😄

[safe flame]

i dont think i will lol

hahahahaha

it will be a pain in the ass

[maiden wadi]

Localization is actually incredibly easy when set up correctly.

You can do it very efficiently using Stringtables, and save a ton of translation cost by not accidentally repeating word uses in places.

[safe flame]

i think i need some time to learn that cuz its my first time using unreal

[icy dragon]

Also Unreal Engine has built in Localization Dashboard, though blacklisting certain FText objects from getting picked up is a chore.

After all you don't want to pay the translator to translate placeholder texts, something that have near 0% chance to appear intentionally.

[maiden wadi]

It's as easy as 1, 2, 3. Literally. 😄

Create a new Stringtable like this.

Add some lines to it.

[safe flame]

lol okay and how you change the language?

[maiden wadi]

Then set it on your Text values like that.

[obtuse herald]

that thing looking kinda complicated

[maiden wadi]

Once you have some texts translated and compiled, you can view it here.

[safe flame]

damn it seems so easy

[icy dragon]

It's a tad bit complicated, but useful for huge amount of text scripts, but also it picks up every single FText that's flagged for localisation.

[safe flame]

gonna check it out now

[maiden wadi]

For the dashboard. You can also tell it not to compile anything except the specific objects you want. Like I have mine set up to ONLY look up those stringtables.

I personally use a ton of RichText. It's so much more efficient design wise to use than the TextBlock in most cases.

[safe flame]

Is this correct with the table?

[maiden wadi]

What does your TextBlock's Text setting look like?

If you set it from the stringtable it'll be greyed out.

[maiden wadi]

Will look like this.

[safe flame]

Oh i understand, no it looks basic for now, default text

i have to transfer it from texts table to the text?

from here?

[maiden wadi]

Yep. Selecte the StringTable, then you can select the string table row.

[maiden wadi]

Perfect.

[safe flame]

Awesome okay, i linked everything

now for example, how can i use another language to those

and maybe we should move somewhere else because this is for blueprints?

[maiden wadi]

This is blueprinty. There's not really a localization channel I don't think.

[safe flame]

Oh okay

[obtuse herald]

this channel gets abused for everything anyways, I don't think it matters

[safe flame]

i have no languages here

[maiden wadi]

First off. Organization.

It's probably best to keep your StringTables in one folder, or one folder tree. I have a UI folder, in it I have a StringTables folder.

[safe flame]

done!

[maiden wadi]

Go to Window in the main editor and open the Localization Dashboard here.

[safe flame]

done

[maiden wadi]

Click on Game, on the left.

[safe flame]

yes, i see that its already open

for some reason mine has a warning

or something

[earnest tangle]

Oh I didn't realize Authaer was finnish

:D

[maiden wadi]

American Immigrant. 😄

[earnest tangle]

heh

[maiden wadi]

That looks right.

[safe flame]

i also have this one

conflict status

[maiden wadi]

Down at the bottom, click on Gather Text.

Afterwards, compile it.

Will take a minute.

Oh. And add whatever cultures you want at the bottom as well.

[maiden wadi]

Add another one just for tests.

[safe flame]

sure thing one second

i will add my main language

[maiden wadi]

Once you Compile, that's how it'll read what you can test in with the dropdown in the widget.

[safe flame]

do i click somewhere for compiling?

on compile text?

[maiden wadi]

Rightmost button at the top.

Yepo

[safe flame]

Okay i had green tick and clicked okay

[maiden wadi]

Kay. Open up a Userwidget.

Should see a button at the top with a planet and "None" next to it.

That None dropdown should have both languages now.

[turbid rapids]

I really want to know what this panel is ?

[maiden wadi]

Perfect. That's how you'll see what people can see in your game when they run those languages. Setting language in the actual application is a little trickier.

[safe flame]

the thing is that its still in english, the menu

that means i have to edit based on language?

[maiden wadi]

You can use these. You'll need to know the locale codes you want to use. Best to put them in a datatable or Dataasset, so that you can also link them with other variables like the Text you want to display in the dropdown.

[safe flame]

somehow

I saved the picture

and how exactly i change the text based on language?

[maiden wadi]

You do. Normally you would send this out to a translation company who is capable of handling that kind of translation.

However. There is an easy way to do it yourself if you want.

[safe flame]

For translating greek i can do that since its my mother language

[maiden wadi]

In the dashboard, here. The small buttons on the right, click the leftmost one.

[safe flame]

yes, it says here 0 (100%)

[maiden wadi]

You'll see things here if your Gather picked up your words from the StringTable.

For instance. My Finnish one looks like this.

[white field]

is casting essentially reloading the entire actor or what?

in terms of performance expense

[safe flame]

I dont really understand, that means others have to translate my texts and i just wait until they finish it?

isnt something to translate by my own like Play game > To greek

[maiden wadi]

Oh

In your Dashboard. Change your slants to the other way.

Content/Game/StringTables/*

[safe flame]

You mean create new string table with greek?

[maiden wadi]

Nah, the lookup path.

Change those, make them all face right. Then try to gather.

[safe flame]

yes i have that one

[maiden wadi]

Your slants are left facing though. \

Try changing those. Then Gather. Your main culture should detect everything in the string table

[maiden wadi]

This is a complicated question. Essentially there is no performance lost for CPU computation for casting. It's nearly free. The thing you cast is a pointer. It's a small memory address that points to an object's location in memory. The pointer can be the object's type or anything it inherits from. So a Character can be a Character pointer, Actor Pointer, Pawn Pointer, Object point. Casting between these is pretty much free.

The performance issue of casting is terribly explained, specially on Youtube and bad tutorials that just repeat things they hear. When you put a cast node into a blueprint, OR even just have a pointer to it in that blueprint's variables, then whatever class that pointer type is needs to be loaded up before an instance of the class it is in can be used. Unreal does this because it keeps copies of things it instantiates and copies them for use. These are CDOs, Class Default Objects. So.. In this case, consider Character. Character uses the CharacterMovementComponent. This means that before Character's CDO can be loaded, CharacterMovementComponent needs to be loaded. Essentially the issue with this stems into places where you load a ton of classes on accident just by loading one class. For low level classes this is fine, but a lot of blueprints point directly to heavy assets like the player's models, weapon models, textures, etc.

The simpler explanation is simply that casting has no CPU cost really, but it can screw your memory use out of control when used wrong. Correct use of SoftObject pointers can largely negate this.

[dark crow]

Delicious circular dependencies

[safe flame]

@maiden wadido you know where i can find localization names? such as en-US, cant find my own language

[maiden wadi]

Try el-GR

[safe flame]

i got these, nothing works, only from the editor

it has to be something else

[maiden wadi]

Greece, or Cyprus?

[safe flame]

Greece

this is how it looks here

[maiden wadi]

Cyprus is el-CY, Greece is el-GR

[safe flame]

for some reason its not changing from code :/

[trim matrix]

wait how can I set up the input button to walk on PC

right now If I press w it just starts running

[dawn gazelle]

If you're talking about a Character, then the normal way is to change the max walk speed in the character movement component.

[safe flame]

i cant find my language lol, english is working with en-US but i cant find Greek

it says here el-GR but it doesnt work on a combobox

[bold prairie]

Hi! Are you trying to cast to the character from the object you want to interact with?

I'm pretty new at unreal, but as i know you cant cast to other blueprints if they don't inherit from the blueprint you are trying to cast them, a way i use to cast to my character is to use a Get Player Pawn node and connect into the cast node as an object

[faint pasture]

Casting is just a question "is A an instance of class B? If so, let me treat it as an instance of B"

[desert flame]

Im spawning a character i wanna posses later, but when i spawn it, it has no gravity so it just floats. Whats the fix to that? Cause i wanna launch it on spawn but launch character not workin!

[icy dragon]

Perhaps the character movement component's gravity scale?

[desert flame]

Nah it's gravity is fairly high. It actually has gravity working when possessing the character, but refuses to move when not.

[tiny swan]

Having an issue with timespans. I have an amount of time in milliseconds, and I want to create a time span out of it then read the values. I can do this myself with a bunch of modulo statements, but isnt this literally what the timespan node is for? The output is -647ms. Worst of all, if I divide the millis number i supply by 1000 and pass it in as seconds; it works as expected. I get the correct time, but I want higher resolution than whole seconds.

if i supply Get Game Time Since Creation, which is an ever increasing float in seconds, i get garbage back out of the time span.

My first thought was this must be some kind of integer wrap around. But integers wrap in the billions, not the thousands.

[tiny swan]

great! thank you! I dont know how i never saw that. I've been on the documentation all morning. 😆

it works perfectly in my use case, too! Thanks again

[obtuse herald]

you're welcome

[odd ember]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Utilities/Time/GetGameTimeinSeconds/ exists as well

[trim matrix]

hey guys

Anyone know how I could fix this issue?

Basically when I start running I'm still in the idle breaker animation

it doesnt stop the animation

[grand hawk]

Is the ProceduralMeshComponent can be traced?

[trim matrix]

hey

[grand hawk]

Why?
