blueprint

[wary fern]

i mean idk

[timid pasture]

Im trying to make a Pickup blueprint but I keep getting an error msg

im very new to this, sorry about that

I think this is it but not sure

I named it class because it's for my class

oooh

in my teachers example it also says none but for some reason it works

your talking about the default value of game inst out right?

thats what game inst out says when pressed

[dark harness]

How can I get the Class Default Object in BP?

[supple dome]

you cant get the object, but theres a node for GetClassDefaults that let you pick some properties on the details panel

[dark harness]

How can I make my property show up on that node?

[supple dome]

if you selected the right class it should be there, IIRC some object types properties dont show up

components neither

[dark harness]

hmm yeah, it's not on there. Trying to get another class that's stored as a property on the Default Object.

oh wait it is there. After picking the class on the node, I had to unselect the node and select it again for the details panel to update. Thanks!

[spark steppe]

not certainly required, but handy if you want to lookup stuff

[cyan surge]

Holy shit, I'm actually so mad

I've been having strange results with starting blendspace animations and them not being at the right place...

Starting position means the time into the animation LITERALLY everywhere else,

Why is it an PERCENTAGE in the blend space!!!!!!!

Actually kinda triggered :/

Like, really wtf

BUT CMON name it right!

Name it Start Position Percentage, for the love of all thats good in the world

and perhaps, crazy idea just do the math and work out what percentage the starting position equates to, why would we have to do it...

You should not have to hover over this tool tip to not get completely destroyed by it....

LITERALLY everywhere else, starting position is a time, not a percentage....

Start Position Alpha...

Start Position Percentage...

Anyone familiar with ue4 console and commands? Trying to spawn an NPC in Days Gone via console? only managed cars/props like: summon bp_SUV_v2_C - but I just cant get any NPCs/animals to spawn. None of them have bp at the start either.

[cyan surge]

The console command will either be to spawn NPCS or not, there may be good reasons that you can't

go email the ?game? dev's man xD

[silver berry]

Okay so its possible they just disabled that and I been wasting hours for nothing? lol

Apparently InventoryDropTable_Animal_Bear_C is the one to summon but nothing spawns. Id imagine if I can spawn cars/props Id be able to spawn NPCs too 😐

[cyan surge]

Yes, console commands for the most part are manually created

A Car is a very different type of thing to spawn than an NPC,

The devs, will be able to answer you google who they're, normally it will be on there linked in or something

[silver berry]

So there's really no way of know what you can and cannot spawn in any game without the devs telling you?

I doubt I'll get any replies for this from the devs lol

[open crypt]

Can someone refresh my memory - I want to adjust the view of a player relative to another actor (or component of that actor) - I can get world rotation of the actor and set the player rotation to that but doesn't forward/right vector come into play at some point (or only I guess when movement is involved)

[cyan surge]

Get can just set the world rotation @open crypt

Now because you said player, you may be using a character that is linked to with "control rotation" to a player controller, if that's the case set the control rotation instead,

[cyan surge]

Yes, and also why do you think the dev's won't reply? were all dev's here, why would you expect any of us to answer you then xD

[silver berry]

The devs from Days Gone?

Well, Im not expecting it but we'll see

[silver berry]

Damn.. was hoping all the info I needed was in the object dump I did. I mean it is but I dunno what info to use or if its even enabled in console. I spawned cars and objects but yeah. I guess I'll have to contact the devs.

how to disable mouse input on widget?

[worldly gyro]

how to remove from container

because if i add i want to remove previous add

like i want refresh the windows

[unique harness]

Start Position Normalized

[unique harness]

store them as you add them. then when you want to refresh, call RemoveFromParent on the ones you stored

[worldly gyro]

i don't understand

it isn't this

[unique harness]

No, you need to create an array that holds UserWidget. After you create the widget, add it to the array

actually i'm over complicating this

[unique harness]

before the loop, just call ClearChildren or whatever it is

[worldly gyro]

i just add child here i want to clear before refresh

[sterile fjord]

That’s the first time someone has suggested a more performant way of doing things and I actually understood 😂 thanks! I’ll put it in

[unique harness]

yes so after the Set node

there you go

[worldly gyro]

ok ty

[willow cedar]

I have a save instance for player to save their settings like FOV and sound volume. I only works for on the hosts game though. Not sure how to get it to work for a multiplayer enviroment

I'm going to guess it has to do with the User Index here

Hm, then I really don't have a clue

Yeah, it works completely

I can use it, quit the game

Then open it, and it functions properly while keeping all my slider values. Its just in Multiplayer it doesn't work

Could be because of how I am using my Widget BP though across players. I have to do more testing, but I think I may know the problem

[ocean dock]

Quick question hive. I want to build an app with 6 pairs of buttons. They add and subtract from 6 totals and the first to make a certain number "wins" each category. It's all widgets and I've figured out some functionality but any tutorials you'd recommend. I've interweb searched all I could think of.

[teal trench]

Hi Hi guys, is it fine to use the billboard component as a clickable target in a turn based game?

[ocean dock]

I've got adding, I need how to set the conditions x= then how do I make other things happen. Kind of, lock the categories and tabulate data

Thanks

Hey guys could you take a look at this video ? i'm having a problem

I'm trying to make a player follow a spline, i'm adding points to the spline , but i'm getting a weird result at the end

[wind sequoia]

get dot product between forward vector and and velocity

and im pretty sure if its less than 0.2 u should be moving backward

but that might be wrong the value

or instead

u get Dotproduct between Forward Vector * -1 and velocity

and if its greater than 0.7 u should be backward

or 0,6

Hey I'm doing the UE4 dart learning module and the dev leading the tutorials player settings drop down menu has additional components in it that I don't have.

Does anyone know how you would add these ?

This is what mine looks like -

There's a bunch of stuff that hasn't been done yet, that appears in the author/instructors game file.

[visual marsh]

I am trying to make a camera crane that is controlled by a joystick. The left stick needs to control the arm pitch and yaw. The right stick needs to control the camera pan and tilt. I tried putting the crane in a pawn blueprint but I couldn't access the pitch and yaw anymore. If there's an easier way, like making a crane from scratch (maybe rigging), let me know. Also I plan on mapping controls to focus and zoom on the joystick as well. I am fairly new to blueprints and UE4, so any help would be much appreciated!

[celest yacht]

But Idk if I missed a step or not, the modules are really helpful but jeez they move at like 5x speed it seems like.

[dry blaze]

Can someone please help me out, I've been trying to set the rotation of my player character for so long and it never works it just sets to a completely random rotation I'm using Player->GetController()->SetControlRotation(NewRotation);

Hi, I have an issue: I have a tool where I am using LineTraceByChannel to trace the Landscape. Latter has unique channel.
It works totally fine in editor, but the trace is not working during the cooking, so the end result is bad in the build. Landscape is persistent.
How can I solve that?

[grand torrent]

Hey. How can I normalize a float that can be of any value to 0 - 1? Normalize wants a range, but I can't know beforehand if the max value is 100, 10000 or 289700.

[supple dome]

find the highest of your floats beforehand

[grand torrent]

So let's say that my highest float is 7751,276 and I want this to be remapped to 0 - 1 values then.

[supple dome]

then plug it in your range

if you want your highest value to be 1, find it, then normalize into that range

[grand torrent]

Ah right. Long day 😄

[rancid quartz]

Hello, I'm having a bit of trouble with some movement math.

I'm in need of a formula/graph that will allow me to move a pawn along a spline using AddMovementInput.

Any advice would be appreciated. I know how to do this with SetActorLocation but in this case, it has to be AddMovementInput so that the movement will be replicated.

Cheers.

[gusty shuttle]

@rancid quartz I know your problem is different but this might be somewhat helpful?

[fleet rivet]

I try to rotate this from the top, but It keep rotate it from the center. I just want to use af cube. How can I change the rotation center (pivot) of the default EU4 Cube. : https://www.youtube.com/watch?v=77sQp2qMHuQ
This is not working:

[rancid quartz]

Thanks, Chris. I've achieved that much, it's doing the same movement using AddMovementInput that's stumping me.

[maiden wadi]

@rancid quartzCan't you convert your intended direction to a simple + or - value, and move along the spline via that way?

Not sure exactly which controls you're trying to use. If it's like an axis input or a vector or whatnot.

[rancid quartz]

That sounds good, but... how? How do I convert it to a modifier if I already know the absolute destination?

I have the destination location each frame/call via GetLocationAtDistanceAlongSpline. I need to give AddMovementInput a vector and a float (scale).

I guess if I have the destination each frame, what I need is the amount of movement input needed to move from my current position to the destination.

[maiden wadi]

Are you using axis inptus?

[rancid quartz]

No, I'm not taking input from a player, I'm just feeding it values.

[gusty shuttle]

Would you guys happen to know how to mask out or not show the ribbon material behind my shield mat?

[maiden wadi]

I guess it depends on what your input data is. If it's a directional vector, you could convert it to a direction along the spline back or forward and multiply it based on how closely the controls face the spline's directions. If they're just simple back and forth floats, like A and D input, you could just use the float to scale velocity along the spline that way by using the float as a direction normalized to -1 to 1 for backwards or forwards. Velocity can be interped up to a max speed, etc.

[pastel sinew]

what reference do i need to plug in here for my own char?

[rancid quartz]

Alright, that's enough to go on. Thanks.

[pastel sinew]

I figured it out, there's a version without a reference

[mental sail]

I'm trying to understand in what situation a montage would not fire any of the events other than the execution one? I have attached an image to illustrate all the outputs it is not firing... what could cause this?

[runic parrot]

i'm not sure that i get the question. The first exit clip happens right after the node executes

on completed is not firing? your montage is a loop?

weird, is your animation okey? i'm doing something similar to what you are showing on the picture and works ok

[mental sail]

That's the montage and the animation

I don't know what is up, hence the question 🙂

I have other animations and montages for other weapons that play OK, just not this one.

[runic parrot]

my guess is the animation is not even playing, as to why, i dont have any idea jaj

[mental sail]

That's kind of what I figured... but not sure how to debug this better.

I went a little crazy here

[runic parrot]

also, probably the error is on the animation itself and not on the blueprint logic, since you said it works ok with other animations

[mental sail]

No errors, the message log would pop up

I am printing now the motage and mesh names before playing, and I see the correct ones...

[gusty shuttle]

Can anyone help me? key words, videos anything? I'm trying to use a Niagara ribbon with my players shield. I need the back to have the inside of the circle transparent but the tail to show after the exterior circle.

[mental sail]

Thanks, and everyone else that helped. It was something silly like this, the animation blueprint on that particular skeletal mesh wasn't set.

[runic parrot]

Anyone knows of a node to move an actor in orbit of another actor? like the moon moving around the earth at certain distance

[mental sail]

I can think of a number of ways to do this, one, would be to have a path around the actor and have the other actor follow that path

the other is to calculate a circumference through BP or code and use that, in conjuction with a timeline perhaps, to set the orbiting actors location

[runic parrot]

yeah, but maybe there's a really simple way

https://answers.unrealengine.com/questions/829137/how-do-i-make-items-orbit-around-an-actor-in-bluep.html

there's a node for orbit, i'm gonna try that one

[mental sail]

Huh, interesting, another might be to have an actor, and then place the orbiting mesh off from the center of the actor, and then just rotate the actor in place (this would require only a simple rotation)

[runic parrot]

yeah

i'm trying to make a flying sword

so when it's resting, flying in orbit around the user. When target is adquiered, go in that direction and slash

thats a silly saying. Even in programming we have a Try function

[open crypt]

[gusty shuttle]

@mental sail Aye, it was a few hours since posting. I could work on something else but man, it was getting to me haha. I know it's possible but it needs some magic. Do you guys ever work on a thing and after a few hours you're like "why do I even need this in my game?"

[mental sail]

I can see why, it would look cool if you figure it out, but it seems like an FX problem not a blueprint problem

Good luck though, maybe come back to it later if you can't figure it out right away

Also, you could probably leave it until the end of the game, since there are probably a million more important things to work on 😉

[floral condor]

Set Static Mesh node is failing on construction script, but working on begin play. Is there really no way to make that node work on the construction script?

if i print the return value of set static mesh it says false and the mesh doesn't get updated

[dawn gazelle]

It works, but I think it may be because you're trying to pull the data from a replicated variable?

Oh... You need to specify the static mesh component you want to set in the Set Static Mesh target.

[vital ingot]

When you delete an actor; is there a way to make it call it's construction script first? I'm designing a little level designer tool, and I'm struggling to update things when I delete the actor.

[dawn gazelle]

This is called when destroying an actor. From there you can run what you need to before the actor's reference is gone.

[vital ingot]

Thanks I didn't realize that existed! Do you know if that runs in the construction script? I'm testing it now, and it doesn't seem to be callable in the editor, but I might be overlooking something.

[severe turret]

its a deconstruction script 😄

Also YOU don't call Event Destroyed. It's called automatically when the routine to remove the actor is called. Then it performs such actions before garbage collection decides whether to remove the object

[dawn gazelle]

This event is called by the engine when the actor is being destroyed - it's not something you should be calling directly. You use this event to call anything you need to when that actor is going to be destroyed.

[random ibex]

Hi, I am trying to make a dynamic blueprint widget. Where would be image that I want to change during runtime. I need to know if is possible to change images by their name. For example, when I type name of a dog the image will change to the specific dog. I am able to change text during the runtime via public variable or document link.  But I can't find the best way how to make it with images.Thank you

[runic parrot]

set the texture by grabbing a file by path

[vital ingot]

Gotcha! So since it's a deconstruction script; does that mean there's a different way of accessing it? Right now when I move my tile there's a check around it to see how it should look depending on what's around it.

Normally that works fine, but for deletion it breaks since I can't get the tile's deletion to be called before it deletes. I'm trying to call a string node to see if the event destroyed picks up anything, and it only seems to work when the game's running instead of just in editor.

[severe turret]

@random ibexYou get the Brush first and then the Image.

[vital ingot]

Oh, and also it would be fine if I had to manually recompile, but I'm planning on changing how I track my tiles to make it more performant so I need to register when a tile's deleted instead of recompiling to do that.

[rotund coral]

I want to break an actor into pieces that can be modularly put together at runtime. But these pieces are more complex than just a mesh. They'd likely be something like a skeletal mesh, a particle system, maybe some sort of sound emitter. I understand that I could create a child actor component and build these pieces as individual actors, but then I'm redundantly creating a bunch of actors.

Is there some way to create a component that can contain other components that can then be attached in an actor's BP viewport? Bonus points if you can somehow preview the pieces in its own viewport.

[severe turret]

No that's not possible in the current system.

A component is a component but it cannot contain a component.

[rotund coral]

Hmm.

[severe turret]

that would lead to circular dependency if that makes sense

[rotund coral]

Yeah, for sure.

Merging skeletal meshes is easy enough, but lets say my actor has a bunch of different hats and each hat has its own particle system with a different attach point on the skeleton. These are the things I'm trying to modularize.

Without creating 14 BPs of the same actor with all the permutations.

[severe turret]

I would check out the recent Live Stream that Epic did on the game "Wrench". It will give you some insights

[runic parrot]

So the flying sword is harder to make than i tought, i need to learn more math >.>
I'm trying to make an object fly towards another object at certain speed and adjusting its rotation at X speed. When it passes through the object, that it just keeps moving and adjust the rotation to go into the object again.
anyone has any idea on how to make this from the math point?

i think all i need is a target point, get the forward rotation from the object to the target and then move the object forward while adjusting the rotation at rotationSpeed, but can't get the math right on blueprint.

[jaunty solstice]

Hi guys. Trying to create a shadow catcher material in Blueprints. Some googling but so far no results. Is this not possible?

[narrow kelp]

@runic parrot Not sure exactly what you want, but you could try adding an impulse every tick (either using physics or your own system) towards your target

[runic parrot]

i figured that what i want is a projectile moving at X speed forward and rotating at X degrees Per sec (or tick) to look towards a target

i think i can do it with getlookat rotation and interp the projectile rotation, the projectile only needs to move forwards. i'm trying to figurate out how to actually do it jaja

[crimson saddle]

Trying to do a Get it Result Under Cursor on a ProceduralMesh but I can't get it to work for the life of me

[rich prairie]

Hey guys. I have a problem with my master enemy. I use begin overlap to add damage, but the faster moving projectiles hit several timer and sometimes skip enemies completely. Do you guys use on hit? Maybe another solution entirely? This is when projectiles can penetrate.

[runic parrot]

you can try with overlap or use complex on the hit.

[narrow kelp]

@rich prairie For really fast projectiles I use a line trace before moving them every tick

[runic parrot]

damn that sounds expensive

[narrow kelp]

not really

its better than relying on physics

[fiery glen]

I gaurantee using collision traces is much cheaper than having it be a full on physics actor

if you have a large number of bullets active at once you might even consider just having them represented as an array of structs instead of actors

[runic parrot]

okey, i got most of my problem solved, i'm just figthing with the projectile component now.

Does anyone know how to make a projectile component move forward even after i update the rotation of the actor?
currently it moves forward, but if i rotate the actor, it doesn't give a f*

[severe turret]

the projectile movement component moves along a vector direction that is world based. So the component rotation wouldn't do a thing. You need to rotate the vector

[runic parrot]

can't i set it up to move locally on the forward vector of the actor? so when i rotate the actor, it moves with the new forward direction?

[severe turret]

yeah if you change the direction vector to match it

[runic parrot]

okey, i was trying to save that step, but i'm gonna try it that way

[faint pasture]

Line traces are cheaper than shape sweeps, which are what the projectile movement component uses internally.

I just made my own projectile movement component that uses only lines traces, doesn't sweep the shape at all.

[mental sail]

So your projectile is infinitely thin?

[runic parrot]

i'm about to burn the projectile component to the ground, i'm just trying to make it move forward and change direction when i rotate it and it's a hell.

[faint pasture]

Just use get x vector from rotation

OR

[mental sail]

have you looked at the "homing" option?

[faint pasture]

Use orient to movement and just change velocity

In default settings, the projectile can face One Direction and move in the other. You can either manually make them sync up or turn on Orient to movement

Making them sync up is just as simple as rotating the velocity as well

[runic parrot]

so if i have the rotator and i want to change the velocity so it moves forward on the new rotation, what would be the math for getting the new velocity value?

let's say it was moving 100 on the X and i change rotation from 0,0,0 to 0,90,0

[runic parrot]

where is that option? i only find "rotation follows velocity" on the component

[faint pasture]

There is a rotate vector node. Rotate your old vector to get the new one

How are you calculating the new direction? What exactly are you trying to do here.

[runic parrot]

i want an actor that moves forward and i can ratote it slowly, like a jet.

and i want it to always move forward

[faint pasture]

Then just manually set rotation and use the XVector to update the velocity

So if speed should be 1000, velocity is just 1000 x JetForwardVector

Done

Each frame, update jet rotation then update velocity

[runic parrot]

let me show you one gif and the blueprint please, i think i'm doing something wrong that is really simple -.-

so i'm rotating overtime the pink actor

it can rotate on any way, but at a certain speed (like a jet)

let's say i setup the projectile movement to initial and max speed 0, rotation follows velocity and velocity (100,0,0)

when the rotation change, how would to change the velocity to move forward with the new rotation? (so it moves 100 forward)

omg got it, thanks so much.

[runic parrot]

it was this simple, i don't know why i was thinking that forward VECTOR was just a float of X

[willow cedar]

I followed a couple Mesh slicing tutorials today, and whenever I go to slice a procedural mesh, it takes a bunch of tries before it actually starts to work. Is this a common issue?

[runic parrot]

only if your knife is not sharp

For some more context, I had the "knife" parented to the camera when doing the cutting.

[dawn gazelle]

Sounds like a cutting edge camera you have then.

[hardy merlin]

I am having a race condition. My NewActor calls BeginPlay the instant it spawns, instead of waiting for a Parent Actor to call NewActor.Initialize on it. Is there some other event I can call that fires on the first frame the NewActor is active?

[runic parrot]

hmm not that i know, what are you trying to acomplish?

[hardy merlin]

The best comparison I can make is Unity Engine. Awake() is called when the component is instantiated, while Start() is called at the beginning of the first frame the object is active.

[runic parrot]

yeah, i had the same problem

but in unreal you should have features to not get that problem, what are you trying to do?

[hardy merlin]

I have an Actor, ParentActor, that calls the following functions: SpawnActor(NewActor) -> NewActor.Initialize().

NewActor on BeginPlay needs to access data that is set up inside NewActor.Initialize but BeginPlay is firing before Initialize is called.

[errant snow]

@hardy merlin your best option is probably deferred spawning. One sec while I find my example

[runic parrot]

why don't you call newactorinitialize on begin play of new actor?

if you are doing a spawner, i just did one really simple today

[hardy merlin]

It has an external parameter that ParentActor provides.

[errant snow]

AActor *Spawned = GetWorld( )->SpawnActorDeferred< AActor >( ... )
// Do stuff here
Spawned->FinishSpawning( DesiredTransform );

BeginPlay on the spawned actor won't be called until you call FinishSpawning

[runic parrot]

can't you just call NewActor.Initialize() and after that call another method that is going to do what you do on beginplay?

it seems like beginplay is not what you want in that case

[hardy merlin]

I was hoping to keep this just in blueprint.

[hardy merlin]

I'd have to ensure I do so at all times, whenever the NewActor is spawned.

[runic parrot]

well, this is a REALLY silly workaround

on beginPlay put a delay of 0.0001

[hardy merlin]

I found a better option

[errant snow]

I'm downright surprised deferred spawning isn't available in blueprint.

[dawn gazelle]

That doesn't seem like a great solution. It's adding a branch that will be run every frame for as long as that actor exists when you only ever need the code behind it to run once?

The delay that Acrisio suggested sounds like a better option. As does moving any logic on your begin play that needs the intialize to be completed to another function/event and perhaps calling that event/function after the initialize is done.

[errant snow]

@hardy merlin I built a custom version of the CreateWidget blueprint node to solve a similar problem. Had values I wanted to set through an initialization call instead of expose on spawn params. So now my init function is a) automatically called and b) all the function params are exposed on the CreateWidget node like expose on spawn ones.

[runic parrot]

Yeah this sound way better. Just run initialize and at the end of initialize run another method to complete the process

Or if you dont want to run anything after the spawn, put a Flag for "has been initialized already" check the Flag at the end of begin play and go from there

[errant snow]

ditto. I think a requirement to stay in blueprint land when there are actual solutions in native is downright weird. unless you have a blueprint only project, which you should only have if you don't know C++. Which I happen to know Grug does.

[hardy merlin]

Apparently you can do a Delay of 0 and it will fire at the beginning of the next frame. I'll put that in my BeginPlay.

@errant snow Prototyping something before nativizing it into C++. Also, Shh. On the internet, nobody knows you're a dog.

[errant snow]

@hardy merlin I think you let that out of the bag yourself by previously posting in the cpp channel 😉
I'm not sure prototyping is a good reason to not use C++. but maybe that's just me. I can do things faster there anyways.

[north hedge]

Has anyone had any success with a loading screen in BP for android?
Doing seamless level loading via level streaming but it freezes on transition

[hardy merlin]

I know the king of things you work on and, and there's a very good reason for you to do C++ exclusively.

[errant snow]

I think you'd be surprised how much I do in blueprint! 😛

[crimson saddle]

I am having trouble with a SpringArm component. I am using it to attach items to when they are picked up. When a component is initially attached it jolts into place before working normally. I believe this is due to the spring arm's lag feature but I can't figure out how to compensate for it

[narrow kelp]

Maybe it has to do with your attach settings?

[crimson saddle]

I have the attach settings all set to Keep World which prevents things from shooting off into the distance

[narrow kelp]

Not sure what your situation is exactly, but you could have some kind of interp until your item is in the correct position, then attach to the spring arm

If you think it's the lag, try experimenting with the lag turned off.

[crimson saddle]

works great with the lag turned off

[narrow kelp]

umm, whats your issue?

Anyone know why this happens?

I set my foilage cull distance to 0. But it still fades out so fast

I don't want it to disapear so fast.

[slow phoenix]

as per many softwares, 0 or negative value usually means default. so instead put in some meaningful value.

[hazy tide]

If I put it any higher than 0 it just dissapears right away

[narrow kelp]

what about making it a really high value?

[abstract summit]

timeline track change when a crate other timeline sometime
Somebody know why?

[hazy tide]

Nah, only 0 seems to make it the furthest

[narrow kelp]

maybe its just the editor.. see if it does that in game

[slow phoenix]

just remember unreal distance is in cm, so even 200 is just 2 meters. @hazy tide

[leaden goblet]

when changing input mode to game and UI, i need to click mouse on game at least once to detect keyboard input again, any idea for that?

ok, the problem is with showing mouse cursor also, not just input change

[narrow kelp]

there is a function on the player con to show cursor

also, try setting the focus to viewport

[leaden goblet]

yes im using it

and the viewport, in which actor?

[narrow kelp]

not sure, you'll have to look into it

[leaden goblet]

this?

if yes, it doesnt do a job

[narrow kelp]

just a vague recollection i have

[leaden goblet]

jesus

im sorry

i found a problem

i have no idea who added it here, and i have no idea it even existed

[rich prairie]

Speed is ~1500. So line trace won't cut it unfortunately.

Melee abilities I usually just set a do once and delay between enemy being able to take damage, but that doesn't work here.

[leaden goblet]

........................................

[narrow kelp]

why can't you use line traces?

it should work great for fast objects like bullets

[sharp fox]

Hello! i have problem with my blueprint becouse i sprint only when im moving forward but if im holding and moving other directions it can sprinting

[leaden goblet]

you want to sprint only when moving forward or in any direction?

[sharp fox]

Only forward but i made it

hey guys in in a widged and i want to put a custum key input as event

to "set visabiity"

how do i get the input Key event ?

[dawn gazelle]

If you're looking to control things within widgets you have a couple of options.

1. You can override the On Key Down function. This requires that you have the widget Is Focusable set to true, and you make sure the widget has focus.

2. You can use Listen for Input Action.

[steady night]

@steady nightyeah sorry forgot to remove text i solved it ! 🙂

@dawn gazelle

altho a question , how do i allow the cursor ?

[dawn gazelle]

Done on the player controller:

So if you've properly set the owner of the widget to the player controller already:

[vital ingot]

Is there an easy way to save a variable across multiple actors? I have a map that I'm reading & writing (It stores my actor's location & object reference), but I need this map to be accessed by all other actors of the same type.

I assumed that it'd just work since they all derive from the same parent BP, but it doesn't so I'm a little confused on how I can share & update this information.

[icy dragon]

You could create one blueprint to serve as a "global" variable storage.

[pseudo pelican]

bit of a conundrum I have that I was wondering if I could get some help with

I set the hit player in the first image

but it receives none in the second image

why is this happening?

[chilly jetty]

Hi i have a question

how can i make a mesh not block light?

[tough burrow]

Set cast shadows to false?

[chilly jetty]

on the mesh?

[tough burrow]

Yeah

[chilly jetty]

its more like

imagine a coin in mario but with a yellow light out of it

but the coin doesnt block the light at its centre

[icy dragon]

Maybe making it emissive?

[chilly jetty]

I cant edit these options

is there something preventing this?

oh i see

wait no i didn't work, I tried adding an emissive color but it still didn't give me those options

essentially I want the point light to come out from the center of the skull and emanate light from it

so basically the skull wouldn't be blocking the light

[icy dragon]

If you didn't have Cast Two Sided Shadows in the material enabled, you could put the light inside.

[spark steppe]

is there any way to define a static bp-function so that i can access it from a simple Object? (function library methods wont show up..)

[pastel rivet]

Is there a quick way to copy actor references directly from the outliner?

I have 135 actors i want to paste into an public actor array in a blueprint

[chilly jetty]

that worked

thanks

[worldly gyro]

why cast to bp is bad thing?

[steady night]

@dawn gazellehey question about the mouse controller

@dawn gazelleyoiu got a sec ?

[random ibex]

I don't know if it's too complicated, but that's how it works for me. Thank you

[dark crow]

It's not?
Pretty cheap too iirc

Only side effect you'll have is tight coupling

[digital nova]

hello, how i can make a procedural mesh to be affected by a cull distance volume ?

[dark crow]

Tru, forgot about hard refs :p

[rapid robin]

Hi! I'm working on an FPS and looking into triggering a near miss sound when player is narrowly missed.

I have put a sphere round the character's head, and it can detect if a projectile passes through it. And so the character knows if that happens but doesn't take any damage in the next frame or so that they had a near miss.

However, my game also has hitscan weapons. Can my trigger/sphere know if it's been 'hit' by a hitscan (weapon)? I guess not, right? So any ideas how best to approach this for hitscan weapons?

[maiden wadi]

Easiest method is probably going to be just letting the initial trace hit the sphere. If it hit the sphere, do a secondary trace on another channel that the sphere ignores to see if it hit the character.

Fair. Always forget to use multis.

[rapid robin]

@trim matrix Yeah hitscan weapons are instant hit types guns. From Wikipedia:* most commonly in first person shooters, is where the programming system determines where the gun/ object is pointing, casts out a ray in that direction when shot, for a certain range programmed into the system, and see if that ray comes in contact with any object in the line of fire.*

Thanks folks. Unfortunately I believe all the line trace logic is happening in C++, so was hoping to keep this logic in the character itself.

[maiden wadi]

So pass the trace to the character.

Trace from weapon, on hit, pass the results to the character. If Sphere hit and not character hit, play passing sound. If character hit, don't play but do damage stuff. If no hit, don't pass it to the character.

[rapid robin]

That's the problem: I can write blueprint logic, but not C++.

[maiden wadi]

Also strongly recommend learning rudimentary C++. You can get incredibly far and understand the engine's systems a lot better with it. If you vaguely understand logical flow, it's pretty easy to read up on. Specially with blueprint knowledge and having Unreal source code to read from.

[rapid robin]

Because, as I understand it, the hitscan (line trace) weapon's main logic is happening in C++. And so I'm wondering if there's a way of solving my problem using blueprints.

[rapid robin]

Thanks @maiden wadi , I'm not bad with logic and have been meaning to get into C++ for years. Should indeed just do it.

[maiden wadi]

Strongly recommend the couple of weeks it'll take. It opens a ton of doors.

[rapid robin]

The weapon's base class is C++. I mean if there's no other way I'll ask my programmer to look into it.

I guess it doesn't make sense to duplicate the tracing logic in blueprints just to get a miss sound effect.

[maiden wadi]

What do you get back from the on damaged event in the character?

[rapid robin]

It's spitting out these parameters:

yes

maybe

haha let me see

(the other people here are smarter than me)

Too complex for my brain right now @iron vale , sorry no idea. Wish you good luck!

Sometimes you need a bit of luck that someone reads it that has the specific knowledge you are after.

ouch

[fiery glen]

does it really need to be 2 navmeshes?

if they can only be on one lane or the other it feels like having them move along the spline offset to the side makes more sense depending on how they need to be able to move

[worldly gyro]

[rancid quartz]

Good morning. I have a math problem I could use some help with.

I'd like to use AddMovementInput in an ACharacter to move from a known start location to a known destination.

Does anyone know the formula I need that would give AddMovementInput the values it needs to arrive precisely at the desired destination?

Any help would be appreciated.

Cheers.

[severe turret]

@worn nebulayou can use the OnOverlap event of the trigger to store a value in an array (or remove it on the EndOverlap). Then compere the value to the number of players.

@rancid quartz You can use a LERP function with takes location A and location B and interpolates in a linear fashion using the Alpha (which is a normalised value of 0...1) and a timer or timeline

[rancid quartz]

I understand how that works with SetActorLocation, but how would I use that with AddMovementInput specifically?

[worn nebula]

Ah yes thank you!

[rancid quartz]

AddMovementInput takes a vector, and a float. I believe it then applies this proportionately to the speed given in the Character Movement Component.

[severe turret]

@rancid quartz you give it a vector direction and the scale value will be in units I guess?

its a normalised direction too

you can use a non-normalised direction vector but I find it easier to work that way and scale rather than scale the vector directly.

[faint pasture]

@worn nebula When a player enters the area, check if all of them are in the area.

[rancid quartz]

So I get the vector from the current location to the destination, and then... what exactly do I give it for scale? My problem is that depending on the speed given in the Character Movement Component, the character will move a different amount.

And I need it to arrive precisely at the destination.

[faint pasture]

@rancid quartz Add Movement Input is meant to run each frame.

[worn nebula]

This is what i've got, anyone know if this is efficient enough? I feel like there's probs a better way to do it

[rancid quartz]

I realize that, yeah. I'll be running it each frame, and each frame I have a destination I'd like it to reach.

[faint pasture]

You should formulate it as "each frame you have a direction you want to go" unless your destinations are like 2cm away.

@worn nebula you need to check if the thing beginning overlap is a player character.

You don't want the counter to increment every time a bullet flies through the area

[worn nebula]

Oh yeah haha, I knew I forgot something

[rancid quartz]

Since I'm intending to move along a spline using AddMovementInput, and I'm running it every frame (on a timeline), then I suppose the destination each frame will be CMs apart. 😅

So I don't think I can just give it a direction, because then, depending on the speed, it will quickly go offcourse.

[buoyant gate]

hi guys,
how do i apply collisons to a spline?
thanks, will be a big help
@ me please

[rancid quartz]

I think I need to take the current location, the direction to the destination, and the speed, and do some kind of operation on it to get exactly the input I need to reach the destination. I just don't know the formula...

[faint pasture]

You need a 2 part calculation of direction.

1. Towards spline
2. Along Spline

[twilit heath]

AddMovementInput normally doesn't take speed, just scale

[faint pasture]

Well scale maps to speed.

[rancid quartz]

But doesn't it rely on the speed setting in the Character Movement Component?

[twilit heath]

yeah, but your movement component does it

when processing input

[faint pasture]

Yes. Just think about it, if you were to manually move a character along a spline, how would you do it? You would move towards the spline and then you would also move along the spline if you are close enough.

[rancid quartz]

Thanks for your patience guys, I'm afraid I still don't understand. 😓

I understand very well how to move along a spline with SetActorLocation and an interpolation node but I need to do it now with AddMovementInput and it's stumping me.

[faint pasture]

Just continually move towards a location on the spline that is slightly ahead of the actors location on the spline.

[rancid quartz]

And it won't matter what the speed is? I guess I just strongly assumed that unless the speed in the Character Movement Component was just right, it would go off course.

[faint pasture]

Scale is a mtipler on max speed. Idk if it works above 1. It's used for analog stick inputs mostly. Just give the CMC a movement input of length 1 (normalize TargetPos - CurrentPos)

[rancid quartz]

So it'll be AddMovementInput((TargetPos - CurrentPos), 1)?

1 for scale?

[faint pasture]

AddMovementInput(Normalize (TargetPos-CurrentPos),1)

[rancid quartz]

May I ask why Scale is 1? I just want to understand.

[faint pasture]

A scale of one just means full input. If you're using wasd keys, you only ever have a scale of one. If you're using analog sticks, you can have scales less than one.

Scale is just a multiplier but I don't know if it works above one

[rancid quartz]

Okay, so it sounds like I've just wasted your time, and I should have just trusted the node to do what it does. 😅

Thanks as always for your time and patience, Adriel. You've helped a lot.

[faint pasture]

The trickiest part of what you're trying to do will be in projecting the current actor location to the spline, and then determining the target position which will be a little bit further along the spline

I'm sure there's some nodes like get closest location on spline or whatever that can do what you need to do

[rancid quartz]

Yeah, I'm using GetLocationAtDistanceAlongSpline.

Oh, I see what you mean, yeah. I'm aware of some "closest to" options. I'll take a look.

Thanks again, and have a great day.

[loud igloo]

Hey guys ! I'm trying to make a character who can take object and this object will block movement if it collide with the environment. How would you achieve this ? I tried with AttachActorToActor but I think that the character movement only take the capsule collider in his calculation. Do you think I have to override functions from the CharacterMovement class to make it work ? 🙏

[languid lion]

Hi

Running into a weird issue

My forward vector isn't updating when my actor rotates

I'm running a box trace

but the end point always matches starting rotation for some reason

[steady night]

When im starting a new 3rd person game when pressinf F1+Esc then it brings out the cursor

where can i find the BP for that ?

[last abyss]

how are u calculating end point

It should be // actor or component world location + actor or component forward vector * range = end point.

[languid lion]

I'm stupid

thanks

[hexed parrot]

ayo my brain doesnt seem to work or smth but does anyone of you guys have an idea how i rotate the platform while the capsule keeps its location on the platform?

the capsule technically doesnt move at all, but it should stay on the position where it is currently on the platform

[gray hare]

So you can return a TScriptInterface in a BlueprintCallable function, but blueprint doesn't let you call IsValid() on interfaces to see if it's null. Is there some obvious way to see if the return is valid that I'm missing?

[past jungle]

I think you can attach the capsule actor to the platform actor and set the rotation to global rather than relative.

[rapid robin]

Can anyone please tell me what you call the type of variable combined of two normal variable types. Bit like a struct but only with two inputs.

[runic parrot]

whot?

[white crypt]

map?

[rapid robin]

YES MAP! Thanks @white crypt

[runic parrot]

multidimensional array or map

[rapid robin]

Been trying to remember what they were called for the past half hour (and it's not obvious if you browse through variable types)

[willow cedar]

I am only able to apply damage and kill players from the Server. If I try to do it as the client, it doesn't register the damage. Is there something I am missing here because I thought the Apply Damage works across the server.

The client also can't damage the server host

I am also using a Actor Component for Health

[zealous sundial]

Any info on this node, somewhere ? can't found anything

[willow cedar]

Figured it out. I needed to run it through the server along with the info needed to know who was doing the damage with what.

[dawn gazelle]

You don't want to do it that way.

Have your server check what is overlapping.

[cyan prawn]

Looks like a simple assign value to variable node. What's the problem?

[dawn gazelle]

Data shouldn't be trusted from clients, otherwise it opens avenues for cheating/exploits.

[white crypt]

and if you are working with listen servers, get player controller will return hosts controller

[zealous sundial]

no, it's more than that, cause it's affect range of the variable.
need documentation link if possible.

[white crypt]

its a temporary variable that you store info

[cyan prawn]

There's nothing more in the documentation. https://docs.unrealengine.com/en-US/BlueprintAPI/Utilities/Macro/Assign/index.html

[white crypt]

its similar to local variables inside a function i guess

or maybe im a bit mistaken, it has been a while since i've used it, but inside a macro you can make "local" variables

which then you assign, basically temporary storing the value while you are doing your math/logic/etc

[willow cedar]

How would I have the server check that?

[white crypt]

do you need server to check it? will the game be competitive, meant to be played with other random people?

if its focused more towards playing with friends, personally i wouldnt worry then

if people want to cheat, they will find other ways

[dawn gazelle]

Run whatever the code is on the server instead. The button press can just be a call to the server, where the server does the logic.

[willow cedar]

I'll give that a shot

Thanks

It worked without problem, sweet.

[dark ingot]

If I have a player character made of multiple components assigned in construction, is there a way to refresh that construction at runtime if I want to swap out one of those components?

[versed sun]

put everything that is in your Construction Script into its own function

they call that function in construction scrip and also begin play

[dark ingot]

Good point. Thank you. I'll give that a go.

[willow cedar]

How would I have the person that just died in a multiplayer game spawn in and possess? Currently it spawns in a new actor, but the Server Host is the one that possess it.

[bright dirge]

You need to give the player controller as argument to your respawn function

[willow cedar]

This is what I have hooked up atm

[bright dirge]

replace get player controller 0 by the player controller you want a pawn to respawn for

[willow cedar]

I don't know fully understand what that would be instead of what I have now.

Do I need to create an index of players?

I also don't think I have any Pawn blueprints yet

Wait, nvm I do obviously

I didn't understand the term

[dawn gazelle]

You can't use get player controller 0 in multiplayer as it doesn't refer to a specific player controller. Each client has its own player controller that the server is aware of. Before spawning the new actor, you must have a reference to the actor that was being destroyed, right?

[willow cedar]

Yeah, the Health component I am using gets a reference to the Owner

[dawn gazelle]

Ok, so that owner should be a possessed actor and you can do something like below to get the reference to the controller that is possessing it. You also have to take into consideration order of operation - the destroy actor should only take place after the player has moved to the new character

[willow cedar]

Yeah, I just swapped around the Destroy actor thinking that. But this makes a lot more sense to me

[bright dirge]

Don't forget ranman that your have to spawn the pawn on the server

[dawn gazelle]

Yeah, same with the possession - that should happen on server.

and the destroy XD

[willow cedar]

Ok, so basically just have all that past PlayerDeath happen on with a call RPC?

And pass the owner through it too

[dawn gazelle]

No. The server will know who the owner is.

[bright dirge]

yep

[willow cedar]

Alright, I'll mess around a little

[bright dirge]

you can skip the owner depending with your setup as datura said

[dawn gazelle]

Really, any health/life math and effects should be happening on server. The server should be determining whether or not someone is dead.

[willow cedar]

Can I use pure cast for the reference?

[dawn gazelle]

Sure.

[willow cedar]

I don't actually know the difference between Pure and the normal one aside from the Execution part

[dawn gazelle]

Pure will do the cast for each wire dragged off of the "As ..." pin. So if you have it connected in multiple places, it'll get executed multiple times. The ones with exec pins the value stays there cached and won't execute multiple times for multiple wires.

Plus the exec one prevents you from proceeding with an invalid reference.

[willow cedar]

Ah, ok

Thanks for helping me better understand it. I'll probably have more questions in the future lol

It worked. Again, thanks infinitely. I can't express just how appreciative I am of everyone's help here.

[frozen obsidian]

https://blueprintue.com/blueprint/vbo-fh76/

I have a RegenMana function in playerbase.
In PlayerPaladin I can use it since I am a child.
But in PlayerMage I throw a projectile so the BaseProjectile is not a child of PlayerBase.
So I can't access the function and I have to use a cast to BP.
But is it bad to do that?
How could I get access? Doing otherwise ?

[limber finch]

How would I trigger an event 3 times each time it's triggered?

Like press space bar, event occurs 3 times

[odd plume]

Loop?

How can I find the playerstate class to override it? There is nothing that shows up when I use the looking glass

[narrow kelp]

@odd plume Could you just make a new blueprint and choose that as the parent?

[odd plume]

That could work, trying to use more c++ if possible. But that should work

[narrow kelp]

I imagine you could make it in c++ if you wanted

[dawn gazelle]

You can make a C++ playerstate if you want to.

[hardy merlin]

Hi. Is there a way to search the content browser for all blueprints that derive from a particular C++ class?

[surreal peak]

Hm try

ParentClass==

Or use the ClassViewer

Should be somewhere under Window. Maybe in the Developer Section

@hardy merlin

[hardy merlin]

That works. Thank you!

[faint pasture]

That sounds like a damn mess. Why would the projectile class have anything to do with mana Regen?

[worldly gyro]

because when the projectile hit the target i regen mana

[faint pasture]

Does the mana Regen over time or just 1 time increase?

[odd plume]

How can I convert the text from that c++ class, to be text compatible with the text Object?

[worldly gyro]

1 time but only if the projectile hit the target

@faint pasture

[faint pasture]

If it regens over time, you'll need some sort of a buff system. If it's a 1 time recovery, just make an event ModifyMana and call it from the projectile

[dawn gazelle]

Get your Choice Text 0, and instead do a "SetText" of it.

[faint pasture]

Projectile just calls ModifyMana on its instigator when it hits

Instigator being the pawn that spawned it.

[worldly gyro]

ModifyMana is a custom event ?

[faint pasture]

Yes. I would actually make a more flexible system with a ModifyStat function inside if an interface but just start simply

[worldly gyro]

because regen mana is already a custom event

[odd plume]

Thanks Mate

[prime berry]

I feel like the biggest noob, what am I missing?
Both are the default plane
the left one is in a blueprint
the right one is in the level directly
Both are set to "Block All"

Why is the line trace ignoring the left one?

[faint pasture]

Then just reuse that event if you want.

[worldly gyro]

but i can't that why i use cast to BP for call this event

[surreal peak]

Because it only hits once. You need a multi line trace to hit both

[worldly gyro]

did you read my code ?

[surreal peak]

@prime berry

[prime berry]

the ray is coming from the left though, I switched the planes here @surreal peak

it should hit the left one first

[surreal peak]

Ah like that

[hollow tusk]

different collision settings?

[prime berry]

shouldn't be

[faint pasture]

I'm on a phone, I'm not crawling through your BP. You can reuse that same event though. Whether it makes sense to is up to you and your design. Make sure you set Instigator when spawning the projectile and then projectile can cast it's Instigator to BasePawn when it hits and call Regen on it.

[prime berry]

this is a new unreal project, I just dropped in that one blueprint and the one plane, nothing fancy

did I just find an obscure bug in 4.26?

[surreal peak]

Is it a one sided plane or something like that?

[prime berry]

it's the default unreal plane, and the front face is facing towards the ray

[surreal peak]

Hm not sure then. What happens if you copy paste, in the level, the working plane?

[prime berry]

OH MY GOD.....

I had "Ignore Self" checked.... well now I know what that does.

thanks! I copied the blueprint and saw them hitting each other that's when it clicked

7 years of unreal and you can still stumble upon stuff like this.

[karmic tree]

Hey i would like to do a thing where when you are near a ledge and press space, it starts this jump animation and than it hangs on the ledge. https://i.gyazo.com/732f3bc7002202a25ea09f1d9bbfa3bc.gif

I already tried to this a lot of time but it seems complicated. And there is no tutorial for this

:[

I already did the hang to the ledge blueprint

But it work only when you do a standard jump before

But i don't want a jump in this character movement

[narrow kelp]

@karmic tree It probably will be complicated. Look into setting the idle animation on the characters animation BP.

[karmic tree]

Yeah it's the same thing for me

But i did a change

wait i'm gonna show

[fading wren]

still have problem to solve. i only start learning blueprints, so problem is . I am using this nodes to turn a player when he hit to the wall, where Val = 2 turn right, and Val=-2 turn left. My problem is make a system to solve when player should rotate to left or right after wall hit

[karmic tree]

https://i.gyazo.com/6c3d158385a4d2011e76eea4edb32554.gif

[karmic tree]

It just misses the jump animation

[karmic tree]

But i don't know how to insert it

[fading wren]

in first case the ball rotate correct

in second

incorrect

[faint pasture]

The same way you insert it when jumping normally

[karmic tree]

Yeah i was thinking about that

[faint pasture]

Or

[karmic tree]

will try tomorrow

[faint pasture]

Have the jump animation be the transition between standing and hanging if you're using a state machine.

Depends on your design. I would prefer to actually jump then when near apex, check if there's a ledge to grab and if space is still held down.

That way you can leap when running and grab a ledge

Or even simpler
If bIsInAir && bSpaceIsHeldDown

i cant relate on GetActorRotation, becuse, if i rotate a wall, it will not work correctly

@trim matrix this is from the wall

"roll your own movement code" what do you mean own code ? something in c++ ?

[faint pasture]

@fading wren are you using Character Movement Component or physics to move that ball?

[fading wren]

ball is just placeholder for character

[faint pasture]

Do you want it to eventually behave like an actual character or like an actual rolling ball?

[fading wren]

Character Movement Component

i already have it. i would like to rotate a ball additionaly

[fading wren]

i want character bounce and rotate when overlap wall collision

i already have it. i would like to rotate a ball additionaly

[narrow kelp]

You might want to get the reflection vector from your original direction and the wall's normal

[fading wren]

ok, interact with wall collision. hit wall collision

[fading wren]

i probably dont need to use Add yaw input to rotate

when i trying to do set actor rotation or something else, it doesnt work properly (just one thick) and it looks like glitch. thats why i am using Add Yaw Input. What is your advice to rotate a character ?

could you pleas add more info here

what information do you need ?

you mean, my fail was, that i was trying to rotate a capsule, not a mesh by SetActorRotation ?

why we need to capsue stop being vertical ?

[faint pasture]

@fading wren If you're using Character, phrase your inputs in the terms of whatever your Character setup is using

That is, modify ControlRotation if that's what's driving it.

[fading wren]

how could i do that ?

[faint pasture]

@fading wren ok start over. EXACTLY what kind of behavior are you trying to get?

[fading wren]

ball hit to the wall. Ball bounce (done already) and rotate to inverted from wall direction.

[manic knot]

Hey so I got a True First Person camera, and would like to reduce the "Head Bob" by lerping the camera location to the camera center, Does anyone know of any examples of how to do this?

[faint pasture]

@fading wren Right now, what is controlling the ball rotation?

I'm guessing it's the Control Rotation since you're using Add Rotation Input Yaw

[hoary cliff]

Hey guys, I have a couple questions about blueprints for particle systems if someone could point me in the right direction I would really appreciate it!

[faint pasture]

@fading wren ok first of all don't use a delay in that chain.

That input node is firing every frame

[fading wren]

could be velocity, i just using add yaw input, because it first what i found 🙂

[faint pasture]

2nd, what is the IsItPush Boolean?

[fading wren]

Wall cast to custom event in Ball, that custom event set IsItpush = true

[brisk tide]

Hey everyone, if my character is very far away from the center of the world the linetrace and MPC stop working. Anyone encountered this before?

[fading wren]

it would be perfect, i dont want to fake it. how to not fake it but rotate?

[faint pasture]

@fading wren ok that's totally the wrong way to do it. You need a one off event, not some Boolean trickery

[fading wren]

great 🙂 how to to id correct ?

[faint pasture]

@fading wren hit wall, set control rotation, ???, profit.

[fading wren]

it works only one thick

[brisk tide]

I have a skiing game and I want my track to be pretty long. Any idea how I could solve this @trim matrix ?

[fading wren]

and looks like glitch

[faint pasture]

@brisk tide how long? You can go kilometers with the stock settings

[fading wren]

it works one thick, than comeback to previously position, and it looks like glitch

[faint pasture]

@fading wren make sure that switch and Boolean aren't interfering with it, just get rid of all that. You don't need it.

Try use Add Yaw Input and add like 90 or so and see what happens

[brisk tide]

at about 163815.0 units it stops working. My character is moving pretty fast so that might be the problem.

[faint pasture]

@trim matrix Check out my physics workaround for a multiplayer space game

https://youtu.be/o0TrJeYYXbk

[fading wren]

i am lost, could you please write, what exacly, what nodes should i connect to custom event in player BP

?

wall cast to this custom event

what node need i use to rotate a player correct

?

[brisk tide]

The linetraces I could do without, the most important is the MPC parameter I'm using as a point in world space to get where the hill is going downwards. Using that I set up the speed for carving.

[faint pasture]

It doesn't help that you're using the wrong words half the time. Do exactly this.

Event hit on Wall
Cast the hitting actor to Character, if it is a Character, call event Bounce(custom event)

In Bounce, try just adding like 90 degrees to Yaw Input. If this works, then modify it to do the math to determine the correct bounce rotation.

[brisk tide]

@trim matrix so blue arrow always points downhill and pink is direction of the player. Based on the DOT between those im adjusting the downhill speed.

[faint pasture]

The correct bounce rotation would be something like RotationFromXVector(ReflectVectorByNormal(Velocity, WallNormal))

[brisk tide]

I had the blue arrow before working with linetraces but i switched it to manual with gates. So when you cross the gate it gets xyz of the next gate. It works better and its cheaper

[fading wren]

@faint pasture

correct ?

[faint pasture]

@fading wren ya try that, does it do anything?

That is on the character right?

[fading wren]

yes it rotate

whole character

really quick

[vast sigil]

Anyone here good with UE4 Audio Blueprints that wouldn't mind me dming for a question I have?

[fading wren]

this rotation is so quick, as like teleportation @faint pasture it does work, could i add Finterp instead of 90 there ?

[faint pasture]

@fading wren you probably want to rethink how you're doing your character rotation. Do you intend for it to always face the direction of movement?

[fading wren]

yes! this is correct word! it should always face the direction of movement! that is my problem, how to do it

[faint pasture]

@fading wren There should be a setting on the CMC to handle that for you

Orient rotation to movement or something of the sort

[fading wren]

@faint pasture

@faint pasture now it looks like it works, but i have a glitches when using "D" and "A" on keyboard

[flat quartz]

I have a blueprint that has lost it's parent and can't open it because it crashes the editor. How can I reparent it without opening it?

[narrow kelp]

Its been a while since I've had that, but maybe try making a dummy "parent" bp with the old parent name

or rename the real parent

its a horrible bug

[fading wren]

@faint pasture unfortunately it does not help + have additional problems. it doesnt solve a problem 😦

[wispy star]

Hello.
Question: Will the Timer that was set for function by name reset if the set timer will be called again?

[fading wren]

@faint pasture thanks for help,need to go

[narrow kelp]

@wispy star I believe it will unless you save the handle to a variable

[limber finch]

Anyone know anything about this build error?

Start out of nowhere

[fossil crystal]

Hi all I have this game where you pickup items and move them / weigh them etc. problem is people accidentally drop them then kick the item and it flies into outer space. Is it possible to have something similar to ctrl z in game? Like an undo

[icy dragon]

#packaging

[limber finch]

Ah thanks

[wispy star]

Um. Why is InterpToMovement Component changes the position of the actor even if it's not activated?

i've even tried to disable tick on it

it still moves the actor to the first point of the path

[limber finch]

So I have this set up to move a camera up and down within a certain range when clicking the middle mouse button and moving the mouse up and down on the viewport

But for some reason, as soon as I click the middle mouse button, the value sets to 0 every time I move the mouse

When I'm not clicking the values appropriate properly

Nevermind, fixed it

[dawn gazelle]

You don't need that timeline. You can place the GetMousePosition on Viewport on the InputAxisCamupDown before the branch.

[fossil crystal]

Is there something similar to ctrl z during a game? To undo last action

[trim matrix]

assigned my custom game instance class in project settings but when I try to cast it inside a Widget Blueprint, the cast is null

[west wigeon]

I'm trying to make a chest appear on the ground, and I'm trying to use a line trace so it gets the monster's location & places the chest right below it. Is there something wrong with the way I'm doing it?

[dark crow]

Any reason in particular for choosing Line Trace Component?

[west wigeon]

Not really, I just want the chest to spawn on the ground, and using physics doesnt work too well

[dark crow]

Doesn't Line Trace Component test against Mesh tho?

I find it odd to test against its own Mesh

To get the ground

[west wigeon]

what would be a better way to get the ground location?

[icy dragon]

Line trace to the bottom.

[west wigeon]

ohhh, now i see, its testing for impact against itself

i should just line trace for objects and look for a static mobility mesh, which would usually be the ground

how would i do that

[dark crow]

I doubt there's any major differences between AddLocalOffset and AddRelativeLocation btw

One considers parent, the other not iirc

You learn something new everyday :D

[exotic pawn]

Does everyone create custom skeletons per character or do you create one skeleton/mannequin and then base all meshes around that?

I don't like the idea of duplicating anim's for every single variation of a character

[dark crow]

If it shares same skeletal features you can reparent to use same anims

If it's exactly the same, use same skeleton

I mean retarget :v

[exotic pawn]

so do you guys use the default UE skeleton?

ya

[dark crow]

I don't see why not

[icy dragon]

Yes, we use UE standard skeleton for humanoids.

There's also more limiting MMD standard, which I hate the most ironically

[exotic pawn]

So when I download a new character mesh (from mixamo for example) why does retargeting create a whole new animBP and duplicate every single animation?

[icy dragon]

There used to be support for UE4 skeleton in Mixamo, and for vague reasons Adobe removed that option.

While Epic is the midas touch of the industry, Adobe is the antithesis of that.

[exotic pawn]

so you guys only have one instance of IdleToCrouchAnim, for example?

[dark crow]

You add 100 but i set it back to 0 right after, will always end up being 0

It still works in Relative space

wat

In the end there's just one transform tho

Relative to World origin aka World Space and relative to the SceneComponent you're attached to aka Local Space

Local is just World + Offset

[glad cloak]

Does anyone remember the metaflag or function you can override to hide properties?
Similar to EditCondition except it hides them, swear that was a thing

[narrow kelp]

Hide Categories?

[glad cloak]

negative, thinking on a per property basis and dynamic

[willow cedar]

How would I do something like this where my plane collision rotates with the camera around the actors location as a pivot?

[burnt citrus]

Hi I have a question
Can I check whether containers values are valid or not?
Not for each loop. I just want to check that containers isn't empty

[mental sail]

One way is to set both of them as children of a "Scene" component, and have the scene rotate, the children will rotate with it...

Otherwise just set the roation of each individual element, I would drive it off a Timeline, that way the value of how much they both should be rotated is driven by the timeline

[fiery swallow]

Almost anything can be plugged into an invalid node

[burnt citrus]

NO

Can I do it without "For each loop"?

[rugged trellis]

anyone know why after destroying an actor the collision remains?

[dawn gazelle]

Do you mean like checking to see if the array has values within it?

[burnt citrus]

YES!!! I want to know this!!! Thank you!!

[fiery swallow]

Oh you could have said an array lol my bad

[willow cedar]

I have Overlap events for both my capsule component, and my collision plane. When I attack with the Plane, it deals double damage because it is making contact with another player twice because of this. Is there a way to make it so only my Collision plane trigger the overlap event when hitting just the capsule component?

I got it. I just turned off pawn collision.

[limber finch]

Pardon the spaghetti.. but for some reason my menu isn't opening after a while

[dawn gazelle]

Rather than setting a boolean, you can store the reference of the widget that is created in a variable then you can check if that reference is valid or not.

When you remove things from the viewport, there's no guarantee they'll continue to exist.

[limber finch]

So how do I save changes made to menu settings?

[dawn gazelle]

Example of storing the widget and checking if it is valid instead.

[limber finch]

I have it set up that way so that the menu is created only once, then later referenced

[dawn gazelle]

You may want to store your settings in a save game object.

[limber finch]

What is that get node?

[limber finch]

I'll have to look into save game object

The player will adjust the settings very frequently

[limber finch]

Damn I don't think this is going to work

I have settings from UI, Level Blueprint, and the Character BP all being adjusted realtime in the Widget

How am I going to save all of that?

It sucks because it's working right now, and the values stay in their place, but it randomly stops working

[dawn gazelle]

Are these "settings" something that will need to carry between execution of the game? Like, start up the game, change some settings, close the game, start the game back up, and the settings I changed should still be there?

[limber finch]

Well I'd like to implement that later on, but for now the values just need to stay there in between opening and closing the menu.

[dawn gazelle]

Ok, then instead of removing the widget from the viewport, change its visibility to collapsed, and instead of adding it back to the viewport, set the visibility to visibile.

So it remains on the screen.

[limber finch]

You can do that?

[dawn gazelle]

Yep

As long as you've saved the reference variable, it should persist.

(saved as in, set the reference in a variable)

[limber finch]

I feel like an IDIOT

[dawn gazelle]

Don't. Lots of tutorials around widgets teach you to add widgets to viewport and remove from viewport when no longer needed.

[spark steppe]

usually thats the right approach

[limber finch]

I was looking everywhere for how to just keep it there, and all I found was destroying it or removing from parent

[spark steppe]

but sometimes you just wanna hide it

[limber finch]

Yeah like the entire gameplay mechanic exists in my menu

[kindred ridge]

hi everyone, I am kinda new to blueprint but I would be curious to get peoples opinion on why it is has been so successful where so many visual programming languages have failed

like what makes it successful? do programmers use it? or just non tech people

[limber finch]

It's more successful in that it's a lot easier for someone with no previous programming experince to jump in to.

It's most successfully used in combination with C++, as it allows you to easily promote values that other people in the development pipeline can access easilly with little programming knowledge.

[kindred ridge]

what do you mean by the second point? promote values?

[icy dragon]

Promote variables and functions written in C++ to be accessible in Blueprints.

[pliant sandal]

Can anyone hop into the feedback and support vc to help with a timer blueprint? Would appreciate it a lot! Thanks

[kindred ridge]

oh so things in C++ can be accessible in Blueprints?

like if I wanted to create my own visual programming language like Blueprint to make something else easier (not game development), does anyone have any ideas or docs of what it would have to do?

like what made features of Blueprint so successful

[limber finch]

Maybe this is more a question for #engine-source ?

[vivid frigate]

How do I get my character able to collide with my enemy (EG, Bounce off him) but not stand on top of the box collider? (2d)

[icy dragon]

I think you can use Add Impulse in 2D.

Alright I'm losing it

I have this set up to move the spring arm up and down

It works perfectly fine when the menu is closed, but doesn't function at all when the menu is open

The cursor will disappear when I press the middle click to activate the spring arm movement

[spark steppe]

does your menu change the input mode?

or occupy the whole screen somehow, which could prevent focus for game elements

[limber finch]

I have no clue how this worked, but it did

Menu only occupies bottom half of the screen

[spark steppe]

yea that rather looks like a hacky workaround

you may have the wrong input mode in the first place, and changing it once appears to fix it for you (however most likely there's no reason to toggle it when the button event fires, but rather somewhere else)

[fiery lark]

Can anyone help me with making aiming down the sights less snappy? I'm trying to get it to slowly transition into the ads camera, but no matter what I try it just teleports into location and looks choppy

Sorry for the shitty pic

[white crypt]

200 is a pretty high value for interp, what if you change it to smth like 5-10?

if that doesnt work try looking into lerp

[fiery lark]

Oh yeah I did like 5 or 10, it makes no difference what I set it to

[maiden wadi]

Is this not being ran each frame?

Judging from the component disables.

[fiery lark]

I have it set to event tick -> run the function

[maiden wadi]

@fiery larkOh. It's because you're disabling the other camera. Has nothing to do with your math. You've disabled TestCam. So the view immediately leaves it.

[fiery lark]

So should I move the deactivate to the end?

[maiden wadi]

You'd need to call it after the interp has gotten the other camera close enough. Realistically, stuff like this is much easier with a dummy camera actor and a couple of extra simple functions in your pawn and controller.

[fiery lark]

Alright I will check that out, thank you!

[spark steppe]

or use a timeline instead of tick event

which can be reset/canceled and ran with new values if the input changes

[fiery lark]

Would I have to take it out of a function to do that?

[spark steppe]

yea timelines can only exist in event graph (iirc)

but the timeline could call a function and pass it's progress to that function

[fiery lark]

I'll check that out. I'm pretty new so I haven't used a timeline yet

[rapid robin]

Hey folks, if you're Playing in Editor simulating two clients, I believe you hear the audio from both windows, even the one that's not selected (and you're not currently controlling). Is there a way to mute one of the windows clients, and only hear the other?

[maiden wadi]

May check and see if creating a sound device for each one allows separate sound controls. Unsure on that one.

[rapid robin]

Ah it seems you can do this:* “SoloAudio” Will solo the audio from the current active PIE window, then when tabbing to other windows, you’ll only hear audio from the window you solo’d. This will allow you to hear audio from an individual’s perspective even though you’re controlling different clients.* --https://forums.unrealengine.com/t/feature-request-mute-audio-on-all-pie-clients-except-one/28898/2

[fading wren]

I am need to rotate player after player hit a wall , rotation should face to movement. I am using SerControllerRotation to rotate a player after hitting a wall. Also using mouse for turn a player, so i can't switch off "use yaw input" in CMC. What is best way to to do rotate player face to movement direction ?

[rapid robin]

Have you tried doing a SetActorRotation?

[maiden wadi]

@fading wrenAre you asking how to set the direction, or how to get the direction?

[rapid robin]

Sounds like it might be a bit jarring from a player's PoV though :/

[fading wren]

How to set direction that face to movement. :)

[fading wren]

It works only one thick, then player comeback in previous position. It looks like glitch

[fading wren]

How to set direction of rotation that will face to movement

[rapid robin]

So you want to suddently invert the player's input direction?

Maybe do a little video of what you're up to so we can see the context

[fading wren]

Player bounce from the wall, but additionally i want to rotate it a little bit(15degreea let say) in same direction as movement

[fading wren]

Sorry, can't do it at the moment

[rapid robin]

You could try taking the player's horizontal input away for a short moment. That might feel more natural (somehting like a walljump)

Give them a little force impulses

[fading wren]

How can I do it ?

[rapid robin]

Then let them regain control after the bounce

Look at the logic where the player's input is happening and make that not happen for a little while when the wall bounce event happens.

I've done something like that with a 3rd person double-wall jump kinda thing and it felt pretty intuitive. No idea whether you're after that kind of effect tho.

[fading wren]

@rapid robin player hit the ball, then bounce in inverter direction by using " launch character". But, i would like to have not only bounce, but rotation too. And rotation should be face to movement that cause by bouncing from the wall

[rapid robin]

SetActorRotation can rotate the player

[fading wren]

Ok, how would it know, how to face it to movement direction ? How will it know, should it turn player 30 degree left or right ? @rapid robin

[rapid robin]

You could try getting the actor's forward vector to know what direction it's travelling in.

Actually that might just get you the direction it's currently facing

You should be able to get the current velocity from the pawn's movement component?

[fading wren]

How ?

[rapid robin]

Sorry the more I think about it the more I don't have a clue what sort of project you're doing or how it's set up. I think I'd need some more info to give you more useful advice.

[fading wren]

Ok, i will send a video later

[rapid robin]

Cool, that'd be useful I think 🙂

[fading wren]

Could i use this velocity for rotation ?

[rapid robin]

You should be able to plug the Velocity into a Normalize node to get the direction it's moving in. You can then break that vector and use the Z value to set your character's rotation.

[fading wren]

Great, thanks, will try it :)

[rapid robin]

Alright, good luck!

[trim matrix]

Hey guys, do any of you guys have experience with a mesh (that simulates physics) suddenly freezing? How could I debug this or start looking for the problem because I'm lost.. Thanks in Advance! 🙂

[mighty quartz]

please help im losing my mind
I cant get the character to teleport/launch/increase speed via blueprint.
I can change the component's parameters and its walking faster but i cant increase it with inputAction.

When I teleport/increase the speed with bp, character just keeps glitching like something is stopping him from moving faster.

Already checked the collisions, nothing is stopping him i dont know what to do next...

[white crypt]

@mighty quartz how you are setting the speed?

need some pictures

[mighty quartz]

even tried launching/teleporting with different methods, same thing happens

[white crypt]

so without blink speed changes correctly

right?

[mighty quartz]

yep, if i change it in the setting it works fine

[white crypt]

you want to teleport character and give him a speed boost, just so we are on the same page

[tough burrow]

Could it be that you change the speed somewhere else in the Bp?

[mighty quartz]

i want to either teleport him or change his speed
just make him mobile when i press a button

[mighty quartz]

i will check

[white crypt]

if you just want to change speed then your first image should work

simple example of sprint "system"

and double check your blink point mesh, if it has collision that it might be the reason why your character is jittering

as well as weapon base

[mighty quartz]

already checked, turned off all collisions

tried your method same thing..

speed is referenced in animation bp

not my code so i dont know if its the problem

[white crypt]

in anim instance its being used for your blendspace, so it doesnt affect the actual speed just the animation itself

so with my example nothing changes? or you are jittering while moving

[mighty quartz]

yes, its the same jitter while im moving

[white crypt]

that usually happens when you have a component attached to your character

did you change the collision of weapon base inside character or inside the weapon base itself?

or temporary remove those components and see if that solves your issue or not

[mighty quartz]

ok ill remove it

[white crypt]

you can open up a clean 3rd person template and do the same there, you will notice that it works fine

[mighty quartz]

yes it should be so simple, something is wrong with my character

ill try recreating it from scratch

using the template

[white crypt]

yeah just after each new implementation try to test it and it should be obvious when it breaks

[mighty quartz]

yup, will do that

thanks for the help

[white crypt]

np, your profile pic is an interesting choice 😄

[mighty quartz]

haha he was a hero in my country

[radiant sequoia]

Hey folks, a client wants me to add some parameters to the PlayerStart that say whether to spawn the VR player, or the standard first person character (for debugging)... just wanted to check I'm right in thinking PlayerStart doesn't really have anything to do with the spawning right, I'd need to change that somehow in the GameMode?

[white crypt]

player start is a reference point where to place your default pawn class

[radiant sequoia]

yeah, so it can't change hte default pawn class

[white crypt]

and you can change that pawn class under world settings or inside your gamemode

[radiant sequoia]

ok, they want just an easy tick box on the spawn to say whether it should be VR or not but... I guess that's not happening.

[white crypt]

you can easilly do that but not with player start

depends on how you want to manage your spawns

[radiant sequoia]

are you suggesting creating a separate spawn manager ?

[white crypt]

i believe something easy as this should work

its inside the game mode

[radiant sequoia]

Sure

So to change "Is For VR?" they'd have to... open the GameMode BP and change the default value

[white crypt]

yeah, but its just one approach out of hundreds

[radiant sequoia]

Sure

[white crypt]

https://prnt.sc/137v2tn

you could make your own player start actor which could hold that info as well

[radiant sequoia]

yeah I've overriden player start, I was thinking of swapping game modes with it if it lets me do that

[white crypt]

or there's even a built in boolean

[maiden wadi]

Why are there two separate pawns for different controls? Why is it not the same pawn with different controls for different control types?

[white crypt]

which checks if theres a vr connected or not

if that helps

[radiant sequoia]

Fair point, the main answer being I've just imported the Start Content FP character for quickness, rather than reimplementing those controls into our VR character.

Plus the camera setup is based on the height of the HMD so that would have to change as well if you were in "Debug First Person" mode

food for thought though, thanks guys.

I have a RegenMana function in playerbase.
In PlayerPaladin I can use it since I am a child.
But in PlayerMage I throw a projectile so the BaseProjectile is not a child of PlayerBase.
So I can't access the function and I have to use a cast to BP.
But is it bad to do that?
How could I get access? Doing otherwise ?

[wind sequoia]

no its nit bad to cast

it only becomes bad when its excessive

like a cast on tick

but even then

u will have minimal performance loss so small u still wouldnt notice

though to be safe whenever you cast save an object reference for future use.
