Use print strings and check your numbers. Tick, print health, print Max health

[lime yoke]

Got it. Thank you!

[trim matrix]

where all at?

[opal nest]

I've used a branch to make sure the function will not run if the player is jumping or double jumping in the Enum Mobility State, however while jumping or double jumping, it still prints "sprinting" and the fov scales up how I set it to when sprinting, Another problem I've found is while the player is sprinting, it continues to sprint after i've jumped

Im using Enums here btw to track the players current mobility state e.g walking, sprinting, sliding, jumping or double jumping etc

[main lake]

don't use a branch here as the Switch on enum is already doing that job for you, just connect all the non walking output to your walk speed

[opal nest]

Thats how it was originally, I added the additional logic with the OR boolean afterwards to see if that would fix it however it didn't

[main lake]

fix what ?

[hearty moss]

that function isnt returning anything of value. add a boolean to the return node called something like "shouldSprint" and make sure you add the appropriate return nodes where you need them, then hook that up to a branch outside the function

anywhere inside the function where the execution stops, it will still return and continue whatever is outside the function

which is why the fov is changing for every enum

[opal nest]

I dont think I'm understanding here, Wdym its not returning anything of value?

[hearty moss]

the function should be returning something you can use to decide whether or not to do the fov scale timeline you have

what its doing atm is fine, you just need it to return a boolean so you can use it for a branch right before the timeline

e.g for all states you want to affect the fov, you connect it from the switch node to a return node (with boolean) set to true

[tropic peak]

Does anyone have any experience in implementing non-physical vehicles? Chaos physics vehicles is a total overkill for what I need, and I'm not sure which approach would work better for implementing a motorbike - **FloatingPawnMovement **(component) or CharacterMovement (component).

[opal nest]

Ahhh so pretty much, the function returns the boolean which sets it as true, then the branch recognizes that its true and will play the fov stuff, and after this I should make the var false when completed?

[hearty moss]

you dont need to promote the return value to a variable. it adds a red circle you can plug straight into a branch

think of the function input as asking a question, and the output being the answer

so yes, thats what it should do, except you wont need to change anything back to false, since you dont need to store the return of the function anywhere

[opal nest]

So as such?

(Took me too long to figure out how to do this LMAO)

[hearty moss]

you dont have to connect a variable to the return node. it should have a toggle box that lets you set what the return value is

[opal nest]

By default it does not

After I delete the can sprint, it does have a checkbox so I'm assuming thats what you mean

[hearty moss]

yes

so anywhere you want to be able to sprint, make sure it returns true

anywhere you dont want it to sprint, you dont need to add a return node (though its good practice to do so anyway)

now your function should return a boolean which you can connect into a branch before your timeline

[opal nest]

So it would be wise to just put this in the other BP instead, and have the function just return true?

[hearty moss]

there are a couple of ways to do this. your setup is fine as it is, but if you wanted to do that you could make the function a pure function and use a select node instead of a switch, and return both the desired speed and the boolean you made

id just keep what you have atm since its efficient for what you want

[opal nest]

Alright, I'll see if it works

Okay so it partly works, I jump/dble jump, It doesnt sprint the first time, However after I press the jump button twice, it still sprints mid air, and the enum prints that its state is currently sprinting too

It also shifts back to walking too

Which isn't surprising because I set it to do that once the action is completed

Instead I think it should check if its back on the ground instead of when the action is completed

[hearty moss]

remove the branch inside the function if you haven't already

[opal nest]

This is what the function looks like currently

Accidentally put sprinting to return can sprint as false on the switch

This seemed to have fixed all of the bugs, it no longer sprints in the air etc

[hearty moss]

it would make it easier for you if you had a single print string for the mobility state on tick

[opal nest]

That would be true ahahha

thanks for suggesting that

[hearty moss]

i believe the "completed" happens only a single time after the release of the control

[opal nest]

I believe it was because I was spamming it so it was completing multiple times, didnt actually check if the person is on the ground before changing the state back to walking

[hearty moss]

right, i dont know the rest of your bp so im sure you have it set somewhere else too

but if you do encounter a bug where you keep the sprinting speed it will probably be from that branch

[opal nest]

Thanks for the help

[hearty moss]

no worries, i hope you learned a bit more about functions from the return node thing!

[opal nest]

I certainly did

[sweet silo]

hi ! how can i make it so that i don't get alot of "accessed none"

[lunar sleet]

hi! In this case, you can use an isValid (?) check on the hit hit actor reference before performing any additional logic. If the ref is null (nothing was hit), it will fail silently

[sweet silo]

oh amazing thanks a lot !

[trim matrix]

is there a way i can make camera zones that are box triggers that control the zoom of the camera like if an area of a level has something i want to display in full like an image for a puzzle, etc, have the player enter the collision box and have the camera switch to the camera zone camera until the player leaves that camera zone, either returning to the main third person camera or at another zone

Hello everyone,
we have the problem that the grass we generate via the landscape material is loaded into the game in batches. In a shipping build, the server and client are already spawned before the landscape grass is fully generated. I’m wondering how other games hide this?

Is there maybe a delegate that we can register for when all patches of the landscape grass have been generated?

Here is the method we use to generate our grass: https://dev.epicgames.com/documentation/en-us/unreal-engine/grass-quick-start-in-unreal-engine

Attached is a short video showing the issue we're facing.

[prisma forum]

I have a flashlight the player carries that has a spotlight attached to the front, and a cone static mesh which is invisible but calls InFocus and OutFocus on ComponentBeginOverlap and EndOverlap using a blueprint interface. My problem is, whenever the player is moving, the ComponentEndOverlap is called, even when the cone is clearly overlapping an actor with the interface. Also, sometimes when the cone is overlapping an actor, it repeatedly calls EndOverlap, without first calling BeginOverlap. Any ideas how I could resolve this?

[empty marten]

I just saw the video and I want to play the game lol

[trim matrix]

mine or the reference 😭

[empty marten]

What even is that game in the video?

Hey peeps,
Why is it if I try and change the brush using the top part in red, I get the errors in the bottom part in red but if I try and use the method in blue, it works fine? What am I missing?

[zealous moth]

is there a way on begin overlap to get an event for when a camera component out of the character gets overlapped?

this and the inverse fails:

it will overlap the capsule but ignore the camera altogether

fixed it! 🙂

[distant grotto]

is there a way to get an array of instances out of the instanced static mesh component?

[chilly crane]

With the Game Animation Sample, what needs to be applied to obstacles to allow the player to vault over them, climb up walls, etc. And what are the limitations to this, like can you only climb up a certain height, or will it keep looping so you can climb as far as you want?

Also, given that the Game Animation Sample comes with a standard licence, it can be used in commercial distribution of games running on UE5?

[dawn gazelle]

If I remember right, Instanced static mesh components only allow you modify their meshes by their index and it's usually limited to basic data you can change about the specific instance ike location and rotation.

[flat coral]

Anyone else wish we could have vertical lines in BPs?

[rancid hull]

in my anim bp my apply additive makes my character grow but when i dont use the additive it workds fine any thoughts?

[iron idol]

If you divide an integer will UE round the number? Will it even work?

for instance if i divided an integer by 1.2

[deep drift]

Hi. Hopefully someone can push me in the right direction.
I have a BP_Projectile (default from the FPS scene).
I want to change its color every time I enter a trigger box. I know how to change it in Material Instances etc.
Problem is: there is no BP_Projectile on the scene before it is spawned so I can't tell it to change its color. How do I approach this? How do I reference something that doesn't yet exist?

[rancid hull]

Well integers are only whole numbers so no fractions or decimals so it will automatically make it a float

[iron idol]

i kinda figured

is there a node for rounding to an integer or converting to integer

lol nvm i should have just searched round in BP

[rancid hull]

i would use the ceil node

[iron idol]

i assume it rounds the number?

[rancid hull]

it takes a float and rounds up or down to an int

[iron idol]

Yea. I should have looked harder. I appreciate the answer.

Hey guys anyone know if it's possible to load a specific sublevel from within a persistent level please?

Basically I want the code to say "load <persistentlevel.level-5>"

or something

[rancid hull]

store a reference to each spawned projectile using Spawn Actor from Class and modify its material using a dynamic material instance. When the player enters the trigger box use the overlap event to change the color of the most recently spawned projectile by accessing the saved reference.

[dawn gazelle]

Electronic Nodes plugin

[rancid hull]

use the load stream level node

[thorny forge]

I think that only lets me select 1 level to load

I'm talking like I'm outside the persistent level altogether and I want to load into a persistent level + specific sublevel

[rancid hull]

Use the Open Level node to load the persistent level.
Once inside the persistent level, you can trigger the loading of a specific sublevel using Load Stream Level

[thorny forge]

So let's say my game have 3 persistent levels for different reasons. If I'm in persistent level 1 sublevel 1, from that place I'd like to press a button that loads into persistent level 2 sublevel 5

@rancid hull I appreciate the help but that doesn't really work. If I do it that way, then everytime I load that persistent level it will always automatically load the other sublevel

where as I need it to always loads into level 1 by default

sublevel1*

[rancid hull]

can you just set the persistent lelvel to be the default map or would that not work

then do Event Begin Play Load Stream Level

[rancid hull]

in my anim bp my apply additive makes my character grow but when i dont use the additive it workds fine any thoughts?

[thorny forge]

No the whole game is already made. I'm trying to create a chapter selection menu and the main game is in a seperate persistent level which automatically loads level 1 as it should

[rancid hull]

mmm tricky im not sure then sorry.

[thorny forge]

it's ok

I'll keep working at it

[rancid hull]

Good luck

[thorny forge]

Thanks 🙂

to be honestly now I'm trying to figure out why my persistent level automatically loads a specific map (level1) without it being told to in a level blueprint

hmm

[wicked cairn]

Has anyone approached using a zone system where when the player overlaps a custom collision for an area, their weather changes to that zone they overlapped? I’m wondering if there’s a way to make a collision wall in an actor that can be customized from the base, like maybe using the custom shape geometry mesh or something

[chilly crane]

Yes! All the time

[thin panther]

No it doesn't, ceil will always go to the next integer up. Floor will go down. Round will go up or down depending on situation.

[rancid hull]

mb

[thorny forge]

Got it figured out, I made an initialise level BP that stays in the persistent level and checks whether I entered via chapter button or not

[rancid hull]

nice!

[faint pasture]

Change a color variable and feed it to the projectile on spawn

Enter box -> change color var

SPawn projectile -> tell it what color to use

[iron idol]

do we need to upgrade to 5.5 to use quixel assets now?

it says my plugin is out of date and directs me to updating UE

[slow steeple]

Hello,

I want to make a combat system where the Ai reacts to their opponents hit direction. So if the player hits left then it blocks in
that direction. If they attack left but a bit lower, the blendspace would blend according to that. My problems are:

How do I dynamically pass the changing hit direction to the enemy when the player moves their camera, strafes, jumps, gets knocked back, whatever would
change the angle of attack so that the Ai could react dynamically during the swing of the sword? I have method of tracing the sword but it doesnt
predict the future swords path, which im not sure if would be necessary or even a good solution.

How do I implement a blendspace that could blend according to the dynamically changing vector?

Even if you don't have a solution, advice would be helpful, thanks.

hey quick question, im having some trouble with the death functionality. after it finishes, the dummy gets back up instead of staying down. Has anyone else run into this issue or know how I can stop that from happening?

the dummy doesnt stay down he just stands up been trying to debug this for days

[lunar sleet]

Usually people replace dead chars with a simple static/skeletal mesh actor that has no logic and doesn’t affect performance much

[frosty heron]

If you are playing montage for the death animation, just create a loop section at the end of the animation.

Problems With Multi User Dev

Hey guys me and my friend have been having a couple issues with Multi User Dev on Unreal Engine 5.2.1, my friend is the Host of the server. First off, everytime i change something on my end he'll experience a quick freeze for a couple seconds, this makes editing the same map and working on really anything together basically impossible. Next, for some random reason after a while of working together, it will be like our versions desync and when I go to save it will get rid of everything that he has worked on and only save my progress. If anybody has any solutions to this I would appreciate it very much.

[frosty heron]

If you haven't tell it to stand down, it's not going to stay down magically.

[mellow coyote]

do i loop the animation montage or the animation itself?

[frosty heron]

To make montage section you will have to be in the montage

[frosty heron]

It's just a section you can define. This way you can have a section playing forever.

[mellow coyote]

is this it?

[frosty heron]

I would drag it to the end of the frame

Also make sure it's looping. Hit the check box and select loop

[mellow coyote]

it doesnt seem to loop the last part

hold on ill record it

[frosty heron]

I already told you how to loop

Yeah you didn't loop it

You just define a section, it's not gonna do anything

[mellow coyote]

I dont see the loop option under the section settings..

[frosty heron]

Read above pls

The check box next to default -> loop -> checkbox

[mellow coyote]

OH SHIT THERE IT IS

sorry for the trouble man

thank you so much man

[mossy skiff]

Hello,
I'm a newbie and have a question about Actors and structure:
If I watch some tutorials people often create something like BP_Base_Something for their different requirements.
Lets say I've BP_Base_Pickup and BP_Base_Interactable and want a child inheriting from both, how would I do that?
Or do you structure it different anyways

[dawn gazelle]

A pickup sounds like it would be an interactable.

BP_Base_interactable -> Things like light switches, doors, drawers, computers.
BP_Pickup -> Inherits from Interactable, made for things that the player can "interact" with to then get that object in their inventory.

[mossy skiff]

Thanks for your reply.
I thought about that as well but wasn't sure because I built both systems as actor component and to have them decoupled I wasnt sure if I should inherit the base from another base related to another ac.
And I was also worried that I get a lot of overhead if I create more and more "bp_bases" for different requirements.
Do you usually have one "master" then ?

[dawn gazelle]

How you structure your code is ultimately up to you, but if things can share a common hierarchy due to similar functions & variables, it's generally better to use inheritance. You can still use inheritance with components and subclass them as well.

[tiny tundra]

Any idea how I can add these items (red) to the array highlighted in blue? In the editor, not during runtime

[mossy skiff]

Thanks a lot, I guess I'm overthinking and should do as you recommended it.

[tiny tundra]

...as far as like - dragging and dropping into the fields on the right, somehow (or something to that effect). Short of setting up a flow of adding them all through a blueprint sequence

[dawn gazelle]

Technically the "buttons" don't exist until runtime. You could do something like this, but I don't think the values in the array will be valid until runtime anyway.

[tiny tundra]

understood, thank you

[young meteor]

Hey folks

I'm trying to move some actors along a Spline but I'm getting a weird result right now from setting their Transform on tick. (see video)

I think it would be better if I could do some sort of interpolation along the Spline instead anyway to optimize performance.
Is there such a node/setup?

I don't want to interpolate between two points on the Spline because then it would cut corners etc.
I want to move the actors along the Spline.

[tiny stag]

hello everyone

I'm new to Unreal engine. I want to change the scale, rotation and location of a blueprint actor with editable number from widget blueprint.

I tried looking the internet for help but didn't find any.

[dark drum]

That looks like you're trying to set it's location multiple times a tick.

[young meteor]

I'm calling this on Tick.
Not sure how I would be setting it multiple times.

[dark drum]

Whats the movement mode set to?

[young meteor]

What do you mean?

If I don't call the function I showed they just "stand" still.

Not sure if it is "height" related.
As in I could be spawning them in or above the ground and they try to pop up/down after transform setting?

[dark drum]

On the character movement component. The movement component performs it's own corrections to it's owner based on it's movement mode. For example, if it's set to walking, you can't alter the pitch of the character as it'll always remain upright.

The change you're making might be conflicting with the movement component which it then adjusts for.

[young meteor]

Default Land Movement Mode is set to "Walking"

[dark drum]

Ok, try adding the capsule half height to the location on the transform you get from the spline.

[young meteor]

Just did a + 150, but didn't seem to remove the problem.

[dark drum]

O wait, you're setting the world transform of the capsule component. Try setting actor transform instead.

[young meteor]

It wants a Target

[dark drum]

There's one specifically for actors.

[young meteor]

Oh, my bad

It works better now but still not great. Recording.

I'm an idiot. Had Tick interval set to 0,1 sec

Sorry

[dark drum]

Nps. It does look like gravity though. You might want to set the movement mode to flying as well as it'll disable the gravity.

[young meteor]

I've set it to none since this would be the new "movement"

I have a minor thing with setting the actor Transform since I can see that tilts the whole actor, and healthbar is tilted (moved a bit) too.

Guess I can set the actor location and mesh rotation seperately.

[nimble wasp]

A parent BP gathers pawn data. How do I access that in a child? I can't change the parent to make that data a variable.

[steep cypress]

So close to finishing my game but I stupidly upgraded to 5.4.
Now my project stutters/lags after working for 5 minutes. Then if I build all levels, it fixes temporarily until I do a bit of work.
If anyone can help with this I'd be eternally grateful and get you a coffee or something, it's so frustrating

[dark drum]

Using STAT UNIT can help determine the general area such as GPU or Game Thread related but beyond that, you'd need to profile. Anything we say here would just be a guess.

[dry sleet]

Do you have any editor windows open, like BP:s or meshes?

I find those often hog a lot of memory and VRAM, closing them helps me.

OTOH it was like that before 5.4 as well.

[steep cypress]

Off the top of my head, dont think the stuttering will occur until blueprints are opened.

I've tested the STAT UNIT but it's hard to know what to do with the information. For example, it said my texture memory was at max. So I increased it by 1GB just for the texture size and max to both go up to the new number.

Is there a clear way of reviewing memory and vram?
I've got the overlay for memory on my screen. But I don't know how to debug from there. For example, it's quite a small game but it had like 150,000 objs. But building all levels, the game and blueprints still run fine for a time with that many objs.

Sounds like I need to read/learn what the profiler does and how to understand its results

[dry sleet]

Are you getting Texture streaming pool over budget or Video memory exhausted errors, then?

[steep cypress]

No errors, just a lag in gameplay. Like blueprints are so laggy it becomes unworkable

[dry sleet]

It's not an error as such but it shows up in the viewport

[dark drum]

Show a screenshot of the values STAT UNIT shows when you're performance dips.

[steep cypress]

Thanks guys, 2 minutes

happy to screenshare as well?

[dark drum]

just a screenshot is fine for now.

[steep cypress]

so when i'm looking at my level in the viewport these sentences would appear?

[dry sleet]

Yes, in the top left

In red

[steep cypress]

no lag:

[dark drum]

It should look like this.

[steep cypress]

Gotcha

[dark drum]

Do any of them ever flash a different colour?

[zealous moth]

wow game and GPU are higher than usual

[steep cypress]

will let you know shortly, im working until it becomes broken again but seems to be okay for now... typical!

[dry sleet]

hah

[dry sleet]

both of those are well nominal for a larger game

[dark drum]

That could just be down to hardware.

[zealous moth]

is it? aren't you all getting 240 fps???

[dry sleet]

lol

[zealous moth]

i'm pulling your leg but yeah could

[dark drum]

I'm pretty sure the editor is capped at 120 haha.

[steep cypress]

here we go:

[zealous moth]

you can lift it up iirc, but packaged games need an explicit cap unless you want to make the CPU catch on fire at 1000 fps

[dry sleet]

Ouch

[steep cypress]

https://tenor.com/view/so-it-begins-raining-rainy-day-théoden-lord-of-the-rings-gif-16521230

Thats with stutter

[zealous moth]

game, so it's something on the cpu logic

[dry sleet]

And what does stat game display now?

[steep cypress]

It'#s starting at 120 going down to yellow/green and repeating over a 2 second cycle

[dark drum]

Ooof, it's the game thread. :/ It's some logic somewhere (could be multiple places) in you're BP's. You'll need to profile unless you only happen to have 2 or 3 BPs to checkhaha.

[dry sleet]

But it's while in-editor?

From what I understand?

[steep cypress]

it appeared to begin, when I added some random nodes to the blueprint. Almost as if there was a cap in the memory and it got to full?

[slate scarab]

Is there a direct way to control the IK Goals via user input? I'm struggling to find a way for direct natural limb control while using the benefits of the IK system. Two Bone IK is not satisfying enough

[dry sleet]

It's very likely that your memory has been exhausted and it's doing page dumps

[steep cypress]

Everything working very smooth, then I add 5 branch nodes and boom

[dark drum]

Show what you added and it's surrounding logic.

[dry sleet]

Very strange and nasty, it might be something with the graph editor then I suppose

[steep cypress]

not sure if im loading a massive amount of objs from somewhere? This is a small, shop sim type game:

[zealous moth]

branches shouldn't cause this

do a binary check

[dry sleet]

Ah, I think I have a hunch

You probably have a very large dependency chain on something

[zealous moth]

remove half of the stuff and see if it improves until you find the cause

[steep cypress]

It's not branches specifically, it's adding anything to the blueprints. Then when I build the level it fixes, until I add some more nodes

[dry sleet]

And when that asset is loaded it loads a huge amount of data into memory, filling it up.

[zealous moth]

dependency? it should all be loaded into memory as soon as the level loads, it shouldn't cause stutter

[steep cypress]

This is the clincher, build all levels fixes this temporarily. And from my reading one of the main things that does is cleanse memory

[dry sleet]

The asset you're working on -- if you right click it and select "Size Map"?

[zealous moth]

widget???

wait, how many widgets do you have active? the cap should be around 74

[dark drum]

I doubt it would be down to this.

[zealous moth]

branches are binary all or nothing. terminal branches on tick don't affect performance at all

can you share the branches

[dry sleet]

Well again it's my understanding this lag happens while in editor?

Not in play mode

Right?

So any lag can't stem from BP logic

[dark drum]

What does leaving store do?

[steep cypress]

I didn't explain very well but both to be honest

[dry sleet]

If it happens in editor that's the important thing

Because then your BP flow isn't the culprit

[steep cypress]

Fires some very simple movement logic

Normally its my code but I think on this one it's my hardware and unreals technical side xD

[dry sleet]

My two crowns is that it's because of linker dependencies

Things like that hard class ref there cause a dependency, so this class (that you're in) needs to load DoorTargetBlueprint before it can be worked on.

[dark drum]

Do the frames dip if you start playing but don't actually do anything? (Idle)

[dark drum]

As this scale it's nothing to worry about lol.

[dry sleet]

How do you know the scale?

That sort of thing can cascade -- before you know it you have almost the entire game loaded into memory at once.

[steep cypress]

No. My unreal engine has two states at this point: perfectly smooth or lag fest

[dry sleet]

And if the memory is exhausted you'll get page dumps.

How much RAM do you have, btw?

[steep cypress]

Lag fest seems to occur when I add anything to the game until I do a "build all levels"

I'll check its working but 32gb

[dry sleet]

Plenty!

[dark drum]

He mentioned above.

[steep cypress]

So check the profiler and maybe I can figure out if my memory within unreal is getting too much?

[dark drum]

Whilst true, depending on the size of the game, that too isn't always an issue. I recently released a game where the only thing I soft loaded was audio files. The whole game was a few GB and would all be loaded anyway.

[steep cypress]

or does frame/game being red tell me it's GPU related

[dry sleet]

Well, that's also true

[dark drum]

I highly doubt its anything to do with memory.

[dry sleet]

Well, if it's happening in-editor I highly doubt it's anything to do with BP flow

[dark drum]

Game is the Game Thread, and Frame is the total for the frame taking into account the GPU and CPU.

[steep cypress]

"build all levels" temporarily fixes the issue until I add more stuff into the blueprint or level editor

That's why I think memory?

[dry sleet]

That's where I'm getting my hunch from as well.

[dark drum]

If the editor runs out of memory it pretty much crashes. Something I experienced a lot when I only had 8GB of ram.

[steep cypress]

Some small context, don't know if it's helpful: my game instance is never changed or altered but each time I press play it ups the appendix on it.
there are some red cross icons on some of the lights

[steep cypress]

True.. unreal does love to crash rather than stutter..

[dry sleet]

Depends on the size of your page file, doesn't it?

[dark drum]

First thing I would do is sort out the lights.

[dark drum]

Unless you have a fast SSD its not always fast enough compared to RAM and causes some error. UE doesn't like having to wait around haha. You also have to remember, unless you actually use all the RAM it's not going to use the page file. (Which he clearly isn't)

[dry sleet]

Sure, from the looks of things there's plenty of spare memory.

But if it's not related to game logic, and running the GC (from the looks of things) fixes it, I don't know where to start drawing conclusions?

[steep cypress]

GC pardon?

[dark drum]

Garbage Collection

[dark drum]

Do you spawn anything at runtime?

[dry sleet]

It's obj gc for running the GC, right?

Just for my peace of mind, next time the problem occurs, try running that?

(instead of Build All Levels)

[steep cypress]

sorry amigo, didnt fix it

[dry sleet]

Then it's something else!

Just listen to pattym lol, I gotta duck out unfortunately

[steep cypress]

Starting to think it could be lighting you know.. started during an upgrade to 5.4.4. So i'm going over those settings. Will report back soon

Thanks Greenosaur, please feel free to message anytime with a query or if you need playtesters, I really appreciate your time 🙏

[dry sleet]

Ah cheers, will do! Hope you get it fixed!

[steep cypress]

Me too! I'm actually almost excited to report what caused it lol

[dry sleet]

Lighting sounds like a good bet, it might be doing something annoying in the background at least

Is anything appearing in the output log while it's happening btw?

Something that chugs our project to a crawl is when it's building Mesh Cards or Distance Fields.

And that can happen super sporadically, when the linker decides to load some asset (for instance while compiling a Blueprint that relies on it)

It should only happen once per mesh in your project unless it's changed, though

Perhaps something has gone wrong with your Derived Data Cache that prevents those from being saved correctly?

[dark drum]

At the bottom of the editor. Start a trace then play until it starts to lag. (keep playing for a few seconds after) Once done, stop the trace.

Once you've done that, you can open the unreal insights, (in the same list) and open the trace you've just done.

You'll get something like this.

[dry sleet]

I suppose it could also be building navmesh, but yeah -- better to profile than to guess!

[steep cypress]

Ignore. Still broken.

[dark drum]

Time to profile. 🙂

[steep cypress]

Yessir

[dry sleet]

You'll have it figured out in a jiffy with the profiler

Then whether or not it's an easy fix is another matter haha

[steep cypress]

Does that mean anything to you?

[dark drum]

Nope, you need to profile like I showed above to find out the cause. All that shows is theres an issue.

[nimble wasp]

A parent BP gathers pawn data. How do I access that in a child? I can't change the parent to make that data a variable.

[steep cypress]

Patty.. that fixed the stutter 🤣 just starting the trace and voila, fixed. Wtf is happening

[dark drum]

Just keep playing until it stutters again while the trace is running.

[steep cypress]

Got it

Stutter file

[dark drum]

On the graph at the top, click one of the peaks to get a breakdown of what was happening.

[steep cypress]

Thanks for your patience

[dry sleet]

You can also drag and select a little region on the timeline to get an average of what's taking time, often that's more helpful (IMO).

[steep cypress]

So it's cpu right?

[trim matrix]

so, im working on an enemy, i want to make it fly around the player and randomly stop and drop an egg, but im not sure how id set up the animations for that, or the blueprint, but i have this flying in place animation rn

[steep cypress]

I can't speak for animations. But you'd create a projectile, that is egg shaped and which has no forward velocity but gravity enabled. And spawn it from where an egg would drop on this bird

[dark drum]

You can use your mouse wheel to zoom in. We want to focus on the game thread row. Looking at it though, it looks like something to do with slate.

[fluid lagoon]

Would anyone have any idea as to why the head doesnt rotate with the camera?

[dark drum]

What widgets do you create and add to the screen?

[steep cypress]

A good question to ask is what causes the rotation? 🙂

[fluid lagoon]

This is my mouse input :D (I just figured that adding the head has a child to the camera would automatically cause it to move and rotate with the camera)

[steep cypress]

There's a simple HUD, tracking money and experience

And when you talk to someone to sell inventory is quite intensive.

The stuttering can happen without playing the game, not sure if it is loading it when I work on a blueprint related to said widgets

[steep cypress]

So does your controller change the camera, the model or both?

And do you want the head to move seperately to the body

[fluid lagoon]

Yeah, essentially the body would stay where it is, and the head would rotate as the camera rotates

[fluid lagoon]

The image above is for rotating the camera with the mouse, allowing you to look in a first person view

[dark drum]

Ok, keep zooming in on the slate tick time one. Below it will be further break down of the functions.

[steep cypress]

I appreciate you're busy Patty but would it make more sense to screenshare now?

[dark drum]

I'm to busy to screenshare.

[steep cypress]

Good news, it's a very common almost expected in games now so I'm sure there's a wealth of tutorials. But I imagine you need to bespoke code that effect. I've found a tutorial here that may be helpful: https://www.youtube.com/watch?v=IMuqrTtLNXg

[dark drum]

If you zoom in it should look something like this which is a break down of some of the functions responsible for the time.

[fluid lagoon]

I did watch this however it's more targeted at bones when Im using just a mesh to rotate, thanks again tho!

[steep cypress]

I may be misunderstanding but it will be a lot easier to do if your head is somewhat seperated from the mesh as a total

Not sure how helpful this is but I think thats zoomed into the game threads section

[dark drum]

You need to pan to recenter the slate tick bit.

[dark drum]

Is there nothing underneath it like this?

[steep cypress]

That would be helpful but ive tried every kind of click?

There's also a good chance this was during non-play. I think I captured the stutter between blueprints and play. And im reviewing the biggest peak (unsure if its play or BP).
I wonder if this has something to do with loading/destroying widgets that are being processed in BP and thats why build all levels fixes temporarily

[dark drum]

You might need to pan around to find it. You can zoom in an out to help.

Hey everyone Im trying to have an icon or symbol that appears next to my menu options when they are selected. Can anyone show me a tutorial or give me an idea of how to have the icon show up when a menu item is highlighted

[elder prism]

Hello,
I would like to know how I can change the play rate of an animation at any given frame, regardless of the current animation frame. Basically, based on a condition, I want to be able to reverse the play rate without the animation finishing (so during playback). My biggest issue is retrieving the last played frame of a specific animation sequence. I may not be very clear, but any help would be greatly appreciated as I haven't found much information online.
Thank you.

(To clarify, I am working with UE5.4 in blueprints, and these animations are animation sequences triggered from a pawn blueprint class.)

More specifically, the workflow is as follows: I play an animation sequence, and during that animation, if a condition (true or false) is met, the animation continues. However, if the condition is false, the animation should reverse from the current frame where it is at the moment.

[final python]

why exactly does the destructor in widgets get called on the constructor? Had to make a bool for it to stop doing it, since I am changing stuff during destruction that doesn't exist during construction

[narrow sentinel]

Anyone know whats going one here I select box in bottom left as you can see

[dark drum]

You'd probably need to ask in #slate for an answer but if I was to guess widgets probably get created and destroyed as it's building the UI layout.

[narrow sentinel]

But someow it selects the BP actor to the right

[dark drum]

What does it look like with just the camera selected? (im assuming it's a camera lol)

[narrow sentinel]

what you mean sorry

[dark drum]

Select just the camera and show what i looks like.

[narrow sentinel]

could my editor be going wierd cause I have rider in background on debug game and debugging whilst I'm working in editor etc

just cause thats one thing I can think of

[dark drum]

I believe it's because the frustum size for the camera. It must include it when checking whats in the rectangle.

[narrow sentinel]

oh strange don't think I've ever had that before

[main bobcat]

hi so i am on 4.27 and i just stumbled on an issue and cant wrap my head around it.
I am using a touch screen to look around the scene in, viewport it detects as both touch 01 and left mouse click which is what i want. But when i package the project and try on standalone it only registers the touch 01. Does anyone know how i can get it to register touch 01 and left mouse click same as in viewport?

[young meteor]

How do I spawn in a Chaos Destruction Mesh at runtime? (or Geometry Collection if that is the right wording)

I want my enemies to break apart when I shoot them, but they are not in the level when game starts. Not sure how to go about that then.

[lunar sleet]

You can just put it in an empty actor and spawn that actor

Geometry collection is indeed the right wording

[young meteor]

Ah okay, so I should not spawn it directly from an existing Actor with a lot of other logic.
I simply create an actor that only has a "GeometryCollection" added.
Then I set the "Rest Collection" to my Mesh I broke up with the Fracture tool.

And when I spawn it and it falls to the ground it will break apart. (Or I should probably add an impulse to it somehow to make sure?)

Maybe like this? (just with a location and impulse defined)

[lunar sleet]

Yes, but beware using set rest collection dynamically (the node)

I’ve had it cause an almost guaranteed crash in every engine version I’ve tried it in

I recommend you make sure it’s set to the right rest collection in editor, beforehand.

But yeah that looks fine

[young meteor]

Oh wow, okay.

So in Editor under Details like this:
Must there be a Chaos Solver?

[lunar sleet]

Nope works without

[young meteor]

Love it. Thank you.

Hello Everyone, I was recommended to ask my question in this server, so I’ll copy and paste below. I hope this is the right channel

“If anyone has experience with Unreal, please help.

I am currently wanting my character to be able to do flip forwards/backwards with the right stick. Similar to how it would work on Steep, Riders Republic, etc. The current issue I have is that when the character flips to be fully upside down, he bugs out. Not sure why its happening, so if anybody has any ideas, it would be appreciated. I have a video that shows what I am talking about, along with a screenshot of how the Blueprint is working. Refer to the 'Air Rotation' bunch.

It seems to only happen when the character reaches that bottom point of the rotation.”

Hi everyone
I’m facing an issue with my widget blueprint, and I was hoping someone could point me in the right direction. The goal is to hide the stamina and flashlight battery widgets in the main menu and options menu, and only make them visible when the player is in the game. I've attached 4 screenshots and a short video demonstrating the blueprint setup and the issue I’m experiencing. Any help would be greatly appreciated
Thank you in advance

[gentle urchin]

1- value = inverted value

[sharp python]

What has been annoying me is that every time I need a reference to game state, game mode, player state or anything like this, I then have to cast it to the appropriate child class, which wastes graph space and is annoying in general. I've been making getter functions in a library that return the right class but I'm wondering if there is an official way. 🤔

[hearty moss]

you could make them macros or store the references in a variable

[dawn gazelle]

A very simple solution would be to ensure you're adding the menu at a higher Z order value which should place it above any other widgets. If you use something like 9999 then ensure no other widgets go higher than this value, then that widget would always appear on top.

If you want to actually hide the widgets, that would require some additional logic outside of the widget itself, such as an event dispatcher in your HUD class that signals when the menu is opened and closed that your widgets can then bind to and show/hide themselves when necessary. You'd call the dispatcher when your menu gets opened and closed.

[gritty aurora]

Okay I will go try this , Thanks Datura

hey, im trying to make a spin move similar to mario galaxy, i have this setup now, it slightly works, only issue is, the part to make it happen if the player is jumping, they have to press the jump input at the same time. also, i dont have logic setup for stopping it yet, im not sure how to do that

[severe ivy]

Hello I have a very noob question about Blueprint. I'm trying to expose some functionality to BP via some static functions:

UCLASS()
class BLEEPSERVERTEST_API USecurityNetworkTestBlueprintLibrary : public UBlueprintFunctionLibrary
{
    GENERATED_BODY()

public:
    UFUNCTION(BlueprintCallable, Category = "Security Network")
    static FSecurityNetwork QueryNetwork(const UObject* worldContextObject, const FGameObjectID& networkGOID);
};

Stuff like that. As I understand, static functions of blueprint library should just be callable, but it appears that adding a worldContextObject makes the system think it is not static, because I get a

This blueprint (self) is not a SecurityNetworkTestBlueprintLibrary, therefore ' Target ' must have a connection.

I have done a similar pattern in other places and it has worked fine, so not sure what I'm doing here wrong. I think it;s the const UObject* thing, but I require a world pointer, so not sure how would I get it otherwise

[faint pasture]

It's the same animation

Why not just:

Input -> Spin -> if in air -> launch a bit

[trim matrix]

thats what i was trying to figure out 😭

[faint pasture]

there's an InAir or IsFalling or whatever bool for character

or you can get the movement mode

anyway, it should be that simple

[trim matrix]

i did that but then the player kept rising forever

[faint pasture]

That doesn't sound right

you're telling me that calling launch character once while in air makes them able to fly?

[trim matrix]

one sec

[prime fulcrum]

Using this code the actor is just appearing on top of the other actor when I want the actor to come up from the ground and devour the player i believe that the issue may be the collision even though I have removed it from all of the moving actors components any help would be great!

[trim matrix]

doing it w is falling makes it work better, but the jumping at the same time as spinning rly makes the player go much higher than the set z value

[faint pasture]

That's not a height

that's a speed

[trim matrix]

shit yea

[scarlet compass]

Must be doing something stupid but I can't for the life of me get a sphere collision to trigger an overlap. I had some custom collision presets set up to avoid using overlap all but they weren't working so I just set both the sphere collision and the other object to overlap all. generate overlap events is checked for both. There are still somehow no overlap events from the sphere collision. But the mesh on my pawn will trigger overlap. Is there something weird with sphere collision that is preventing overlaps?

[iron idol]

anyone know what this means?

[lunar sleet]

Hi! I'm having an issue with camera views in multiplayer.

Problem:

• I'm spawning a camera for each player and trying to set their view to that camera
• It works fine on the server but clients aren't seeing through their cameras
• I'm getting all the correct prints, so the logic is executing

I've verified the camera is spawning but the view target change isn't working on clients. Anyone know what I might be missing?

i have a crouch and groundpound setup, but when i hit crouch, it pushes the player into the floor, the groundpound works completely fine, but crouch not sm

[crimson agate]

I am developing a game where players dress up characters.

In the game, there’s a process where users can dress up the characters. To make this process feel different from traditional dress-up mechanics, I want to allow users to adjust the character’s pose freely and then dress them.
What I am curious about is how to implement a method to let users change the character's pose dynamically during runtime.

The idea I’ve come up with is to provide a UI that allows users to directly manipulate the character’s bones. Could you give me some guidance on how to implement this using Blueprints? Even if it’s just an overview, I would appreciate it.

Alternatively, is there a way to make the Control Rig UI accessible during gameplay?

I confirmed that it’s possible to move bones using Control Rig in Blueprints, as shown in the image below. However, the issue is that the UI feels too inconvenient. I want to create something similar to the UI used in Unreal Editor.

[storm vigil]

For certain states (walking, running, reloading) what do you prefer over using booleans, gameplay tags or enums? Why and why not?

I guess enums are best for movement states that dont need to overlap

This is for single player fps game with inventory. Thanks

[main lake]

Personnaly I would go with enums but there will be an issue if you can do multiple states at the same time, so for instance, walking and running, it's perfectly fine as you can't do both at the same time however "reloading", you can be walking and reloading at the same time or running and reloading or idling and reloading, so that means you will need alot of enums just for that reloading thing. Let's not talk about having a state like crouching that would pile up the complexity of using enums in this case 🙂

[dawn gazelle]

Gameplay tags are nice because you can have them in a hierarchy and you can use a single gameplay tag container for all of your state. The only downside is you can't really do a switch or select on a gameplaytagcontainer, you can only check if the container has a specific tag or query it, etc.

[undone bluff]

reloading def does not belong in that, you would have exclusive states for movement like idle, walking, running, inair, crouching, sliding, ziplining, railgrinding, wallrunning

the reason having an exclusive list like this is good is because you can have values associated with these states that you can interpolate between

[storm vigil]

I did find these (select and switch for gameplay tags), which i think extends the tags hehe
https://www.fab.com/listings/8ef04a28-c7ce-4015-97ba-4cf49667a0fa
https://www.fab.com/listings/58a21054-ca60-427d-a12c-c070f17395a8

[undone bluff]

then stuff like reloading could be a gameplay tag on top

which could act as a modifier for the movement speed or overwrite it for the duration it's active

I've seen mover also does something like that, I think the states are just an array of structs there?

[steady night]

how do i change a material param via blueprint ?

the set float parameter is for " audio parameter blabla"

cant find anything on the materuial

[lunar sleet]

Create dynamic material instance node, then drag from its return to change the param. If it’s a mat instance to begin with, it should change instantly, otherwise you’ll need to reapply the material iirc

[steady night]

thansk!

[steady night]

how can i make it block everything beneeth

[frosty heron]

probably better asking in #niagara

[young meteor]

If I use the "Fracture" tool to fracture a Mesh and create a Geometry Collection, will it then use/save the materials the mesh had?

My concern is that if I create some Geometry Collections I spawn in when I destroy an Actor, and then later change the materials of the Actor I destroy, would there then be a mismatch in the materials/colors?

So for example I have a white aircraft mesh, then I make a Geometry collection to use with it. Then later I change the color/material of the aircraft to black. When I then spawn the Geometry Collection I made it would still be white right?
And can I get around it somehow?

[frosty heron]

do one and find out I guess

how are you gonna change the material of the actor you destroyed

it's already gone

can't fix the dead

[queen heron]

so this is weird
for some reason, when that line trace from below detects something, the Obstacle Check event stops receiving ticks, yet funny enough, the second slot in the Sequence node still ticks 🤔

hang on, lemme check something else

yeah this is super weird

this blueprint is executed inside a custom ai controller blueprint

right, I think I know exactly why this happens

yeah, it all works fine now

yet somehow, the ticking line still no longer shows that is firing

must be a visual glitch

[frosty heron]

from my experience, it's not to be relied on

aside from that visual, debugger on blueprint doesn't always work as is all the time from what I read

[young meteor]

No I mean, its more of a design change I guess. Before I/other even play the game.

Just saying if I make a Geometry Collection now, and later decide I want different colors for my Aircrafts, I would then have to go back and make new Geometry Collections for all aircrafts, and make sure to replace them in the Actors I spawn with the Geometry Collection etc.
So it's not a problem game-wise. More workload wise.

[queen heron]

I'll need to be rebuilding this blueprint tho, cause the way I'm setting the obstacle detectors just makes it harder to work with

cause the blueprint animation and blueprint interface are involved

and I can't trust this kind of workflow I made 😅

like this for example
sometimes it returns null and yells out errors

[frosty heron]

if you have a blueprint pointing to your abp instance, that's not a good sign

[queen heron]

so best I move back to using the character blueprints to fire out line traces that do stuff

[frosty heron]

well, where do the line trace take place atm?

[queen heron]

inside the ai controller

[frosty heron]

that's fine?

it's the brain of the AI

if the AI needs to do the line trace, that's a place to store the logic

[queen heron]

yeah, but I want to reuse it in later projects

[frosty heron]

you can make a generic system then

either using inheritance, or components

[queen heron]

I think for the box collisions that handle jumping ai, I'll just reference the character instead of the ai controller

but then there's the part where I need to have it reusable

so that I won't need to make changes to the blueprint just so it finds the right overlapped character

complicated stuff 😅

[shadow holly]

Hey not sure if this is the right channel to ask in, but does anyone know what order the array of actors are in when using SphereOverlapActors? Is it done by distance from the origin point, or just random or something else? Thanks

[queen heron]

whatever actor is overlapped by the sphere, it will be added into the array by overlapping order

and no, this is the wrong channel

you can go here instead #ue5-general

[shadow holly]

That's what I would've thought for a sphere trace, but with the SphereOverlap its stationary, so they all overlap at once so I wasn't sure

[shadow holly]

That makes much more sense thanks I'll ask there

[queen heron]

anything that happens in the game engine happens by order

[young meteor]

This thing still works like a charm. 🙏

One minor thing though. You said I should be very carful of changing Geometry Collection because it often crashes the game.

Do you know if it is an issue to change the materials at runtime?

Then I don't have to go back and redo the Geometry collection every time I change a Material/color for design reasons.

[wide smelt]

Hey! We are running into a funny issue. We got a UI element in the 3d space (a waypoint with distance marker).
If we call a function on the widget from an actor, there appears to be a delay / lag with projecting, if we call the same function straight from the widget, everything works as expected

we where running into a similiar quirk when calling the function from an event inside the widget

Are there any known issues/gatchas etc... Actor and widget communication?

hmm might be related to tick groups...

[hearty rain]

Hi UE Gurus !

I am implementing on UE 4.27 teleporters that send a request to the game instance to stream levels. Once the levels are all streamed, which is checked by a timer that evaluate the “is loaded” bool for every level packages, a notification is sent to the teleporter which will then disable the load screen widget associated to it.

What I really don’t understand, is that it works perfectly in editor and PIE, but when packaged it’s locked.

I have used for each loops with an interator to avoid issues with the latent property of the level streaming node.
All my levels are named based on the full reference path (game/maps/levelstreaming/name), and I have told the packager to cook all the level objects inside the “maps” folder.

I’m wondering if it has something to do with the behavior of the game instance being different between editor and packaged …

Thank you in advance !

ahh, i see

thanks

they aren't really own nodes, but get added to existing nodes

ah

the powerpoint isnt the best at explaining it lol

what node do i need to use to make an actor ragdoll? im trying to make players ragdoll when they die, but i dont know what node it is

[hearty rain]

Set Simulate Physics on the mesh

to true

[dreamy mountain]

by default or using a node?

[hearty rain]

the node is "Set Simulate Physics" 😄

[dreamy mountain]

i figured, i just didnt know whether to set it by the node, or to have it enabled by default

[hearty rain]

if you enable it by default the character will be in ragdoll mode right away

[dreamy mountain]

it doesnt, but now its weird

one sec ill get a vid

they just phase through the ground

[hearty rain]

what are all these errors ?

[dreamy mountain]

its to do with the gun

its because of how ive done the interactable system

its just temporary

[hearty rain]

that's weird some of them ragdoll and some phase through the ground

[dreamy mountain]

oh no

that one ragdolled one

thats just the skeletal mesh in the world

thats not an enemy

[hearty rain]

can you show the blueprint of your enemy character plz ?

[hearty rain]

how are the collision set in your skeletal mesh ?

because typically when you ragdoll, the mesh detach from the collision capsule, and it looks like all the collisions are handled by the capsule

[hearty rain]

Here it is

you need to use query and collisions

so in your blueprint, change your collisions settings

not here

[dreamy mountain]

ok

[hearty rain]

connect the mesh to that after you simulate physics

hey im trying to make a mega mushroom type effect, rn when the player hits the collision it sets there scale to increase to 4, along w speed adjustments etc, i put them into the functions in this screenshot. but if i add a destroy actor the shrink to normal never happens, but without a destroy actor the player can keep getting the growing power up, which i dont want to do, how could i go ab fixing this?

[hearty rain]

you want to destroy the trigger box ?

[dark drum]

This sounds like a job for an actor component. You create an actor component that manages the growing and shrink of its owner (what it's placed on). The mushroom would get this component from what it overlaps and call the grow function. Because the logic is no longer on the mushroom, you can safely destroy it without worrying about when it should shrink.

An added bonus is that you can have other things interact with the component allowing for a more unified system.

[trim matrix]

so move the functions into an actor component?

[dark drum]

Yes, this would also allow you to use the same component on other things to have the same behavior.

[trim matrix]

oki thank u lemme try

so i made one and added the functions but im not sure what to do next

[dark drum]

The component would go on the thing you want to grow/shrink. (in this case the player character)

[trim matrix]

oh

[dark drum]

Once you've done that, pull from the 'Other Actor' on the overlap event and use the 'Get Component By Class' node to get the 'Grow' component. First check if it's valid using the isvalid node, if it is, call the grow/shrink function on it and destroy you're mushroom. This would replace the logic you already have connected to the overlap event.

[trim matrix]

including the cast or keep the cast too

[dark drum]

No need for that cast as now it'll just be based on if the thing overlapping has the component or not. For example if an NPC had the component it could in theory work for them as well. (assuming the component isn't doing any type specific casting for the player character)

[trim matrix]

oki one sec

like this?

[dark drum]

Yes, there is the other isvalid node though which would make it a little cleaner. It has the branch built in. 🙂

[trim matrix]

so now i get that but im confused on how i call the functions

[dark drum]

pull from the return value of the 'Get Component By Class' and call the function from it. have it called if it's valid so you don't get a ton of access none messages.

[trim matrix]

ah ok so then destroy actor? or i wanted to add a time limit on the growing before the player is shrunk back to the og scale

[dark drum]

I would just destroy. I would make the grow component handle when it should shrink back down. You could have the mushroom pass a desired duration through the function then the component can deside how it wants to use it.

So if the player goes over another mushroom while big the component can decide if it just adds the time on or if it'll cap out or a mix of the two.

[trim matrix]

i have another item setup that shrinks the player too

[trim matrix]

im confused on this, add to the function? or the component blueprint itself in the event graph

sry 😭 trying to make sense of this lol

[dark drum]

As in an input (probably a float) on the function for the max big duraction that mushroom gives.

[trim matrix]

like this?

[dark drum]

As the input yea. A few things regarding the rest though. Instead of getting the player character specifically you should use 'Get Owner' which will get the actor it's on and instead of casting to the third person character, just cast to character. You can still set the actor scale and access the movement component from it as they aren't specific to the third person character.

As a side note, you can get and store this on the component on begin play if you'll be calling it frequently.

[trim matrix]

was using a cast to my player bc i change stuff w the camera once the player has collected it, does that change things

[dark drum]

You can use the 'Get Component By Class' and get the camera component from the owner. If the thing it's on doesn't have one it can skip updating the camera stuff.

[trim matrix]

i dont think that will work w how i have it to change

would the cast work since this will be the only thing using the powerup?

[dark drum]

Instead, i would use an event dispatcher then. So when they start growing, have it call a 'StartedGrowing' event dispatcher. On the thing that uses the component, you can then bind to the event dispatcher and have it does something, in this case update the camera.

[dreamy mountain]

for doing an fps, what do most people do for a line trace to the middle of the screen which can also be used by AI to shoot forward

[gusty shuttle]

Quick question: This node, for In Is Recursive, what does that mean exactly?

[violet bison]

this thingy, it should identify the damage type right?
but it just add some other words and it isn't treated as that damage type

[barren dove]

Hey folks, quick question:
I'm looking at having quite a lot of actors (turrets) rotate towards targets and fire (in 2d), feeding the turret a target is handled.
My question is, for the actual rotation of the actors, what is a performant way of doing it? I'm guessing having (hundreds?) of actors on tick or on a short timer smoothly rotate towards their target is going to get pretty taxing.

[dark drum]

Recursive means it calls itself. I would assume in this example, it would check each layer and update accordingly until there's no more layers to check/set.

[trim matrix]

im confused, make the dispatcher in the grow component? or in the player blueprint

[violet bison]

actor tick rate?

[gusty shuttle]

Thanks for answering. In this example, I'm loading the game mode in, I want to load in some data layers then once complete, I can spawn my character. In this case, I think I leave it unchecked right?

[dark drum]

in the grow component. You would then call it in the grow function you have. You'd then implement it on the thing that the component is placed on. (The player character in this example) so it'll update the camera stuff.

[trim matrix]

so like this?

[dark drum]

Sort of, you can unhook the stuff to do with the camera and just call the event dispatcher instead. The camera stuff would be implemented on the character itself and triggered when the event dispatcher is called. This way the grow component doesn't need to know or handle anything to do with the camera.

[trim matrix]

ok then set the camera stuff up where?

[dark drum]

In the third person character, right click on the grow component and go to add event, you should see the event dispatcher you created. Add it to the event graph and implement the camera change logic. 🙂

[trim matrix]

change to this?

[dark drum]

Almost. Like this. You can remove the get component by class node for the camera as well as it won't be needed with the camera stuff being moved to the third person character.

[dark drum]

There's another get owner where the target is actor component.

[trim matrix]

so like this

[dark drum]

Yea.

[gusty shuttle]

Is there a way using blueprints to check what a data layer's state is ? (unloaded, loaded, activated)

I know I can set the state, but I'm having difficulties Getting the state

[trim matrix]

now this?

[lunar sleet]

No, it’s not an issue, easy to do. create Dynamic material instance helps too

[dark drum]

That looks fine. If you test it it should grow.

[trim matrix]

yea it grows

[dark drum]

On the component you can add some logic (possibly a timer) that will shrink the owner based on the time that was passed through. You might want to create another event dispatcher that's called when it shrinks so you can adjust the camera again.

[narrow sentinel]

when I box select in the top side views etc is there a way for it to ignore the camera frustrum ?

cause at the moment it seems to be taking it into account when I box select around it

[dark drum]

Probably not but you could lock the camera in the outliner.

[narrow sentinel]

thing Is I don't think i've ever had it before like in a normal UE

[wicked cairn]

Anyone have any ideas on this zone system idea?:0

[trim matrix]

so set timer by function?

[narrow sentinel]

I'm wondering could it be something with my UE as I've do it from code at least created the project ?

[dark drum]

You could but I'd use timer by event instead.

[trim matrix]

ok then make an event that sets the player back to the og scale?

[dark drum]

yea

[trim matrix]

oki one sec

in the event graph for the component or in the grow function?

[dark drum]

Just create a function call shrink in the component.

[trim matrix]

i have one

[fallen glade]

I have a blueprint that spawns a bunch of sphere that I need evaluated in simulated play, when added they appear like image n1 but in game they turn to image n2, trashed or none to then magically reappear on end play ? any idea?

also in some old levels everything is working fine? I really don't get it

So I found this is an issue only in a new "Open world" and "Empty Open world" level? What?

[fallen glade]

something about world partition? I never touched it

[hearty rain]

If I want to manually stream a level without the latent node, but by directly setting the "should be loaded" bool to true in the level package, will it do it automatically or should I request a flush ?

[fallen glade]

This was it if anyone else stumbles into this

[sour smelt]

Hello, I need help for a "bug" i think, I was doing some changes to my FirstPersonCharacter_BP, and I didn't liked them, so I did some Ctrl+Z to remove them, but then my player wasn't being affected by gravity or movement, I could only move the camera, so I restarted the editor and now the editor crashes whenever I try to play with that character, is there a way to copy and paste the character without the bug? (cuz I don't wanna do it all over again)

[brittle raptor]

Does anyone know if there's currently a bug with setting Enum type variable in BP?

[lunar sleet]

Not usually, what’s the issue?

[lunar sleet]

Is your details panel blank with you click on the char movement component?

[sour smelt]

no

[lunar sleet]

Well either way, assuming you have zero source control

[brittle raptor]

Was trying to help a buddy of mine debug his code and it seems that setting the variable didn't actually change it's value when we were looking at it through debug watch, it was very odd

[lunar sleet]

It really depends on what you’re changing tbh. Some in-engine enums might be editor time editable only

[brittle raptor]

It was one he had made and we were trying to change it inside a function, it wasn't marked private or anything either

I'll do a test on my end to see if I can reproduce it or not

[lunar sleet]

And you’re certain it didn’t change or just didn’t show in the debug watch

[brittle raptor]

It's possible, we also used it in a print as sanity check and the print said it changed but when we used it as part of a conditional it didn't evaluate as expected so I'm not sure which to believe as being accurate lol

[lunar sleet]

Yeah, test on your end and then show the code if still occurring

[brittle raptor]

Seems to work for me but the watch value is not working for me either so that may have been part of the problem

[lunar sleet]

yeah, I could see that. Watch is not always reliable

[brittle raptor]

Better the watch than the code I guess lol, I'll have to take a closer next time I have a chance and see if I can get it figured out, thanks for your help

[queen vault]

How do I get it so I can control the camera with the mouse. Here is the list of components for my player as well as the movement for my input.

Add controller Yaw doesn't work for me

[lunar sleet]

check the use controller rotation settings on the char/camera

[severe tendon]

How could i make it so that when a projectile impacts an actor, said actor gets destroyed

Like, Shooting an enemy

[queen vault]

Which one do I check?

[lunar sleet]

make sure the actor and projectile are set to overlap or block each other, then use the Actor Overlap or Actor Hit (respectively) event to trigger your logic

[lunar sleet]

the ones under pawn probably

tick things and test, that is how you iterate

[queen vault]

Ok the left and right work but not up/down. Any ideas?

[severe tendon]

How exactly?

[lunar sleet]

sigh

[lunar sleet]

show updated settings

[severe tendon]

with the "On component begin overlap"?

[lunar sleet]

I said Actor not component

but yes, if you go with overlap, make sure the projectile is set to overlap the target and viceversa. Also make sure generate overlap events is enabled

[lunar sleet]

take a look at the FPS template and compare Epic's code and setttings with yours to see what's missing

[severe tendon]

For some reason the projectiles dont collide with the enemies

They do with the walls, and they get destroyed

but not with the enemies

[lunar sleet]

You need to adjust your collision settings accordingly

[severe tendon]

Which ones exacly?

[nimble lichen]

how can i make a turret rotate toward something if i want to use DOT product and avoid using find look at rotation

[thin panther]

as a question, why do you want to avoid the latter?

But finding an angle between 2 vectors using the dot product is a pretty well documented math topic, I'd give it a google

[faint pasture]

in 2d or 3d?

[pure jolt]

hello guys, does anyone know how to retarget skeletons for a bow? So I can play some animations for the mesh that I want it's skeleton to be retargeted

Can I do that from ue or should this be made on blender? Not very familiar with skeletons and such as you see lol

[lunar sleet]

As of 5.3 or 5.4 you can retarget #animation in UE

[pure jolt]

yep tried that and says Retargeter could not find source root bone

[lunar sleet]

See #rules on crossposting btw

[pure jolt]

on my bad!

[lunar sleet]

Maybe the skeleton you have is not compatible 🤷‍♂️ . The channel I mentioned might be able to help

You can also just use the skeleton editor to make a new one btw

[nimble lichen]

3D world but only on the Z axis

[faint pasture]

You can feed the dot product of turret.right and the direction vector from turret to thing to control yaw

Are you trying to come up with the desired rotation or to have something more like a control loop?

[dark cedar]

Blueprint Runtime Error: "Accessed None trying to read property CallFunc_GetLocalPlayerSubSystemFromPlayerController_ReturnValue_1". Node: Add Mapping Context Graph: EventGraph Function: Execute Ubergraph BP Player Blueprint: BP_Player

not sure how to fix?

[broken wadi]

Could be that you need to possess the controller before enhanced input subsystem becomes available.

[dawn gazelle]

Accessed None = You're trying to access a null variable. Your "Get Player Controller" function there isn't returning a valid value by the time this begin play is firing or it doesn't have a valid Enhanced Input Local Player Subsystem

[dark cedar]

so i just delay the begin play?

[dawn gazelle]

No. You should only be executing it when you know the player controller will return valid.

The timer there also isn't great. You may as well just use tick with such a low timer frequency.

[dark cedar]

so fix?

[broken wadi]

The player controller must be valid if the character is being possessed by it so what if you move the part for the enhanced input over to the Event Possessed and see if that works instead of on event begin play.

[dark cedar]

so why isnt my PC valid?

so the exec of the timer into the exec of the add mapping context?

[broken wadi]

When you spawn in a character it needs to be possessed by a controller to receive inputs.

[dark cedar]

heres my PC

[broken wadi]

But when you try to access "Get Player Controller" using the pure function you've made it fails to "Get Controller" when target is pawn because that pawn has no controller assigned to it. But looking at your screenshot I can see there's an Event Possessed which means you do possess it (hopefully) somewhere else after spawning?

How is this character added to the level?

Are you spawning it in? Is it placed into the level directly?

[dark cedar]

yes

[broken wadi]

which

[dark cedar]

placed into

its a floating camera

[broken wadi]

when you click the character on the details panel search "possess" and adjust accordingly.

[dark cedar]

auto pos player 0?

that works i assume

[broken wadi]

wait that might be for split screen multiplayer

[dark cedar]

im def not making split scrn lol

so im possessing the camera

and can move with WASD or ARROW keys

but my mouse cursor movement isnt working

same error as well

[broken wadi]

You made a character or a pawn?

[frosty heron]

Is this the pawn / character bp?

Assuming it is not local multiplayer, then begin play is too early

[dark cedar]

yes pawn

[frosty heron]

By the time the client load the character into the world, it does not have a valid controller yet

[dark cedar]

how to fix?

[broken wadi]

are you trying to make just a flying camera?

or a full on character

[dark cedar]

just camera

im basing my design loosely off of the UE demo Crop-down

[frosty heron]

You will have valid controller when the server send you the acknowledgement

The event I used is Acknowledge Possession

That's not exposed to bp though

[broken wadi]

Just need to grab the controller then make it possess the pawn. Can do that on the game state.

[frosty heron]

So you can kind of call client rpc from on possess by the server, by the time the client fire the rpc, the controller would be valid

I hope.. haven't test

[dark cedar]

ex?

lots of big words fried my brain 😂

[broken wadi]

Even easier, take the Game State on begin play, spawn in your pawn at whatever location then get player controller and have it possess the pawn.

[frosty heron]

The straight forward solution is just to use acknowledge possession. This event is called on client after possession by server.

[broken wadi]

I think its single player

[dark cedar]

no not SP

MP

[frosty heron]

Rider is free btw, probably a good time to get into cpp so you can expose useful functions and features.

Blueprint multiplayer is limited as f

[dark cedar]

so redo all of this in CPP?

🙃

[frosty heron]

You can just expose the event to blueprint

[dark cedar]

oh really

[frosty heron]

And use that event to bind your input

Acknowledge possession

Begin play is almost the wrong place for multiplayer for majority of the time.

Because begin play will just run whenever the actor comes to the world. Means for client, it is too early for many things. One of them being, it has no valid controller yet.

Race condition is something you need to address

[broken wadi]

Game Mode > Event OnPostLogin or Event HandleStartingNewPlayer (both come with a controller reference) > Spawn in your pawn actor > use controller to possess the pawn.

[frosty heron]

Isn't onpostlogin game mode thingy

[broken wadi]

yep, I use that to spawn replicated character actors on the server

[frosty heron]

@dark cedar you should read the compendium in multiplayer section dozens of times.

You will get into a lot of errors not knowing how to run code on who and which machine does what.

Getting controller on clients on actor they don't own will also return null since client only know their own controller.

[dark cedar]

Ok ill look it up

[frosty heron]

Read, fail, repeat.

Work on basic replication, know how to use is locally controlled, switch has authority to filter who does what. Know net roles,

Then you can start with some practices like changing the color of a model. Then try a door next.

[dark cedar]

will do

im super new to Unreal so learning a lot very quickly

[frosty heron]

Being new and multiplayer doesn't go really well. If you are not versed in OOP I will strongly advice against starting multiplayer project

Not trying to gate you in anyway, but I would give that advice to my self looking back

[dark cedar]

Yeah ive heard that a lot

[frosty heron]

The big challenge is having to deal with multiple instances of the game. You will get more errors than you asked for and IMHO that will be an obstacle to your learning.

[dark cedar]

i figured since my project was mobile that it would be easier

[broken wadi]

mobile is even more difficult imo

[dark cedar]

ive been wrong so far lol

[broken wadi]

Have to optimize even more and deal with packaging issues

[frosty heron]

How does mobile multiplayer even work without making your own backend? Is there already a platform out of the box for unreal engine for mobile?

[broken wadi]

Which part of mobile tho?

If you need a dedicated server for player inputs that can just be linux whatever distro

But mobile listen is something I dunno anything about

[frosty heron]

I'm gonna stick with steam and listen

If the game make money by some miracle, then I will attack dedicated next

[zinc ermine]

anyone know a good tutorial to create an equipment system with using data assets?

[sacred jasper]

Possibly very silly question: I'm going through an early tutorial regarding UI, and it had me make a basic button widget blueprint for us to reuse. It has an event graph where we set the font size to be equal to a public variable. This mostly works, but I'm noticing a discrepancy in the resulting font size. When I give it 14 for the variable, it sets the font to 18.67. When I give it 20, it sets the font to 26.67. It seems like the resulting font is always 1/3rd larger than the provided variable; what's going on here?

Sure enough, adding a "multiply by 0.75x" node to the font size variable results in the variable matching the resulting font size. Very strange.

[sacred jasper]

I tried putting a breakpoint on the event graph to check the value. I've unplugged my variable and am just trying to set it directly to 15. 15 appears to be the number being passed along, but the resulting font size remains 1/3rd larger (20).

[frosty heron]

Maybe something to do with dpi scaling

[sacred jasper]

I've made no adjustments to it, so it's at whatever the project defaults are

[frosty heron]

Try #umg

[sacred jasper]

Ah, thank you so much! Apologies for asking in the wrong channel!

[frosty heron]

They r hidden by default. I hope someone versed in umg can help you there.

[shrewd lagoon]

Is there a specific downside to the fact that my interface functions w/o a return are implemented as custom events vs overridden functions? I might just be doing custom events wrong atm but they make my event graph really messy and I like the contained nature of functions, but it seems wrong to add a return value just so that my implementations get put in functions

[frosty heron]

A function does not neccesarily need a return value

You can make a function that doesn't return anything

[shrewd lagoon]

Right; the issue I'm running into is if I have a blueprint interface, but then I implement that function; it gets dumped into the event graph 🤷‍♂️

[frosty heron]

Blueprint becomes spaghetti real quick if you work on your core system imo.

The most you can do is collapsing the events to nodes and write comments

[shrewd lagoon]

yeah I'm feelin it

[frosty heron]

I would favour components over interface, especially for equipment.

[shrewd lagoon]

That's the plan! I was just finding an example in one of my random prototypes 😄

[lunar sleet]

I finally used an interface in my project again, been like a year since last time 😀

Only because it made sense to use get actors implementing interface

[trim matrix]

i have a dumb question but im not sure so, im trying to make an enemy class/system to use and build upon later, but not for like a slasher game, im making a platformer, and havent rly been able to find many good tutorials for platformer enemys and movement, where should i start?

[faint pasture]

Just try to do the thing IMO

What do you know how to do already?

[trim matrix]

i made an enemy that when the player enters a trigger box the mesh of the enemy moves closer to the player if theyr still in range, but then nothing happens the enemy mesh just stays on the character i havent done much w enemys other than that

[hexed owl]

Working on setting up a mech builder. I have multiple components that are either static or skeletal based on needed animations. (gunfire, reload, etc.) Is there a cleaner way to list a single entry for each component outside of this? The CharacterMesh is my movement skeletals, so they stay. the heirarchy after that is what im looking to simplify where possible else i'll have like 20 things there for just the mech parts.

[stiff dock]

I'm working on a shop sorting system where you can sort items by rarity. To do this I'm using an int value for the items from a data table. For whatever reason, the value I ALWAYS receive is 0 for each items rarity value. The lowest number actually set in the DT is a 1, and it goes up to 5 if the player has it. I've restarted my engine, the MUE server, and have saved and compiled with countless changes. I've refreshed all the nodes everywhere that deals with my item systems, and even rebuild half of my code from scratch

I previously had to add a new variable to the structure before for the items, and that populated instantly and worked perfectly the moment it was in. I don't understand why this new integer isn't working and why none of my items have it, despite all the data moving around properly

[trim matrix]

trying to make enemys like this

[stiff dock]

nvm, it works for some reason now. This engine makes me wanna rip out my hair

[gentle urchin]

You can always just swap if its an engine problem ☝️

[sick sky]

Sounds like a BP struct issue

[nimble lichen]

like a control that tells the turret which direction to rotate on the yaw based on the players location relative to the turret

[faint pasture]

yeah so dot product the direction towards the target and turret.rightvector

Although, why do you need to avoid FindLookAtRotation?

[frosty heron]

Bp struct should be avoided for that reason. Changing the struct data especially after its been used somewhere normally a recipe for disaster. Mainly the corruption, unknown struct error or resetting to default values.

You should declare your struct in cpp as it doesn't have any of the issue above. It's not even hard without coding knowledge since you can preview and copy the header file from the struct assets.

[late shuttle]

So I'm learning the Math Expression node... anyone got any good ideas on how to generate a point cloud inside a specific density/spacing range relative to the circle radius?

[fallen glade]

is this still a thing? I had a game prototype absolutely ruined by this in the past

surely it's a bug?

[frosty heron]

Still a thing on 5.4 , I am guessing it will still be a thing at 5.5.

The general consensus is, it will never be fixed.

[hearty rain]

Had never managed to make 5.4 working because It kept freezing 5 sec every 10 sec ...

[fallen glade]

lovely

[hearty rain]

Anybody know how to get rid of that warning ? "No Value will be returned by reference. Parameter : both arrays"

[frosty heron]

Perhaps you can't pass by reference

And you most likely have reference ticked. Show the detail panel of the event.

[hearty rain]

ok I ticked pass by reference, compiled, unticked it, compiled, and it's gone

thanks

UE is such a diva

[mossy skiff]

Hello,
I'm thinking about making a dialogue and was wondering if it's possible to "wait" inside a function, until a selection is made via button press in the UI and only after that continue and return from the function?

[lunar sleet]

No

Regular functions need to run in one tick

Just run your function and act on the return value when you’re good and ready. You can use a dispatcher call if need be

Might also be a use case for coroutines but you’d need to go cpp

[mossy skiff]

Alright, that info helps, thank you :)

[frosty heron]

You would want a latent task

Or coroutine function

[mossy skiff]

Can I implement this in BP or cpp required?

[lone folio]

BP bros, why wont this grab the bool value from the BT? always false, in debug, and in the BT, it shows true

[frosty heron]

Blueprint debugger (watch list and the like ) not reliable

Or watching values from pure function

I actually never used it but I heard from a number of ppl that it doesn't work as is.

[mystic forge]

Is someone willing to try and help me with an anim notify state issue i have?
Basically I'm doing the following in a blank project in 5.4.4 (also tried the 5.5 preview):

• Create an Anim Notify State Blueprint
• Override the Begin function and add a print string for "Begin"
• Override the End function and add a print string for "End"
• Add the Anim Notify State to the quin idle aninmation
  Now on stanndalone this works as expected and at the beginnging and end of the notify the messages "Begin" and "End" get printed.
  But on play as client those messages seem to print every tick instead.
  I couldn't find a matching issue other than UE-217698, but it doesn't quite sound like this one.

[narrow sentinel]

Anyone know whats going on here ??

You can see as I move around in Wireframe perpesctive theres black outlines of other stuff in the world oddly

[dry sleet]

I get those too, always figured it was just a rendering bug

it probably is

but it's pretty annoying

[narrow sentinel]

I'm wondering if it's something to do with nanite being enabled and wireframe

[severe tendon]

How can i destroy a certain actor with a projectile?

This doesnt work :/

[dark drum]

What actor? What the projectile hits?

[severe tendon]

An enemy actor

And the standard projectile

That comes with unreal

[dark drum]

What the projectile hits would be the 'Other Actor' on the overlap event. You can check it's what you want and if it is, call the destroy actor using the 'Other Actor' as the target.

[severe tendon]

This is the code on the enemy BP

Like this? @dark drum

[undone bluff]

other actor returns an instance, it will never be equal to the class. Generally you'd want to even avoid doing this instead checking if the hit actor has a tag or implements a component and if so calling a function in said component or using an interface, but you can still do what you're doing using a get class node

[frosty heron]

Whos destroying who?

[severe tendon]

The projectile destroys the actor

[frosty heron]

ok, but any actor?

even the walls?

floors?

the sky?

[severe tendon]

The enemy actor

[frosty heron]

You can just check if the other actor is of type Enemy actor

[severe tendon]

I didnt set any type though

[frosty heron]

casting is a type check

[undone bluff]

oh true the cast literally is a type check too

[severe tendon]

Ah

[undone bluff]

the equals wouldn't work, but if it did it'd be redundant

[frosty heron]

blue pin = reference to instance
Purple = class

[undone bluff]

i.e. the reference you get from the hit is for that very specific unique instance of the enemy

[severe tendon]

Ok, that worked

Thanks a lot 👍

[silent stag]

Hey, when my character crouches, its feet sink into the ground. It seems related to the capsule component, and moving the mesh up slightly while crouching doesn’t look natural. Does anyone know of another solution?

[dark drum]

Show what it looks like.

[silk flicker]

Hey people, please I need some help! I'm using metahuman and i can't pass a variable for the look at function. I tried casting the metahuman bp and then reference the animation blueprint and then set a variable from the current (BP_Switcher) that I'm working to send a variable (a camera location) and the casting fails for some reason, and the connection seems impossible. I tried implementing interface, and nothing works. Even if i tried to fetch the variable from the Event Graph of the animation bp it said out of scope and also the casting didn't work as well. does anyone have any tutorial other than this: https://youtu.be/NZmQPSKf7YY or this https://youtu.be/8skq8t_Fffk for an NPC to look at the camera you want via 3Dvectors? I'm working with Animation BP and i don't know if i can add control rig at the same time. Any help or direction would be much appreciated

[dark drum]

I'd say its an issue with the animation not being positioned correctly. You might be able to get away with enabling force root lock but if not you'll either need to move up your skeletal mesh or move the animation up. (This can sometimes be tricky)

[silent stag]

its not related with animation when character crouch without animation still sink into ground

[dark drum]

When you crouch the capsule component gets smaller (as it should) this moves the skeletal mesh down. (which again is perfectly normal) As I've mentioned, you'll either need to move the skeletal mesh up or modify the animation.

[fiery moon]

or move the capsule down

[silent stag]

i use move to component for my mesh with timeline but does not look natural

[dark drum]

The capsule is the root so that would just move the whole actor.

[fiery moon]

then move the mesh up :P

[silent stag]

yes i did that already

[frosty heron]

Are you using cmc?

And how do you crouch? Show codes

[frosty heron]

This is why

You are trying to implement your own crouch code but you didn't calculate the offset correctly.

Cmc already handle crouching, there are some works behind the scene that calculates the final mesh offsets, etc.

[silent stag]

i also try with unreal crouch node still same result

[frosty heron]

You should just use the crouching function in cmc if you are using cmc

[silent stag]

i dont use cmc

[frosty heron]

No issue on my end

Well the you are not using the crouch function in cmc if you are not using cmc

Issue here is you most likely offset the capsule

So your character will sink naturally

Since its transform is effected by parent

So you need to offset the mesh so it stays on the ground.

How? I dunnoe, maybe look into cmc crouch implementation

Quiet a bit of work from what I recall

[silent stag]

yes this is working but here’s a bit of bumping when crouching and uncrouching, and it doesn’t look good

[frosty heron]

It's not an easy job

Only lead I would say is to see how cmc implement crouch

[silent stag]

If I want to use CMC, my character class and controllers need to inherit from the CMC class, right?

[frosty heron]

Character already use cmc

Cmc is a componrnt

But it's tightly coupled to character class

[silent stag]

ahh i miss understand man sorry

ofc i use cmc

[frosty heron]

Then just change the crouch height in the settings or something along those line

Then call crouch function when you want to crouch

@silent stag Only 1 setting actually

[silent stag]

cant use that im using smoothsync and i have to set false replicate movement

trying to adjust this move component to mesh

[frosty heron]

for what purpose are you using that plugin?

and I don't see the connection between what you said with the actual crouch function

the crouch function offsets the capsule half height, based on the crouched half height, then do some stuff to calculate the character's final mesh offset

[silent stag]

When I'm not using SmoothSync and playing on the server with 50-60 ping, the character's movement looks choppy, and it doesn’t look good at all

[frosty heron]

I am not using SmoothSync, my movement is not choppy

is your movement choppy in editor too?

[silent stag]

in 50-60 ping yes

[frosty heron]

ping don't matter if you code correctly

you need to work with CMC framework

what ever bandaid you have isn't a solution

actually ping don't matter at all. The only time it matter is when the character bump into something on high ping, then server will have to correct

[silent stag]

let me test again without sync

[frosty heron]

and by ping don't matter I mean if you work with the system as intended

you can't have smooth movement in multiplayer with blueprint alone

the part where you need to toggle the bit flag can only be done in C++

multiplayer bp is very limited, especially for fast action game

[silent stag]

thats what smoothsync does

[frosty heron]

at most, you can do turn based / card games

Smoothsync will not be a bandaid

but if you think otherwise, well let me know if it work
Also still not seeing the connection with the crouch function

Hi, how to make bool state from adding child widget button?
Lets say If I click button A state selected, If I click it button A again state Unselected. And If I click Button B state selected, unselected button A.
I can get it working on adding manually button since I can have multiple event click. But im confused with adding child way.

[silent stag]

it does not replicate cmc is crouching when yo set false replicatte movement

you can add another bool for that but same result anyway

[frosty heron]

well you are turning off replication entirely and using a plugin that interpolate transform as a way to "fix".
that's not a bandaid I want to afford because I need the thousands of codes in CMC especially for networked movement.

[late cave]

why would this crash PIE in 4.27?

[frosty heron]

You want to make a generic widget that does just that.

W_MasterButton -> Contains all the Mybuttons that can be added at run time
W_MyButton -> Store internal state (Selected / unselected)

you can have event dispatcher in MyButton when a button is clicked
This will call function in your W_MasterButton that can do w/e it wants (e.g turning the state of all other buttons except the last selected button)

[silent stag]

I’ve tested it at various ping levels, and the current result looks much better than what CMC provides

[frosty heron]

Nah my guy, you just never use CMC correctly for multiplayer

it's not something you can tackle without biting the bullet

[pure jolt]

Hello guys, does anyone know why my character glitches out when playing a “hit reaction” anim that I have? Also when dying he again glitches and looks weird. What could cause that?

[frosty heron]

CMC is battle tested and what is used for fortnite, Unreal torunaments, etc

your plugin literary just forcefully apply transform

[silent stag]

you have a point but i dont have that settings for now

[dark drum]

This is how I currently handle 3rd person crouching. It's probally not the best way but I use a spring arm for the camera so it allows the camera to smoothly transition down. For the animBP if crouching is true, it moves to a crouching anim. I might include the transition anims in the animBP as well instead of using a montage.

[dark drum]

You'd need to show what you mean. I would say a glitch is a pretty broad term.

[dark drum]

The node itself wouldn't. What message do you get when it crashes?

[silent stag]

This is very close to mine, i have different problem thanks anyway

[frosty heron]

diamond pin = reference.
fk around with it and you may crash

[silent stag]

You can also add this to prevent uncrouching if there's something above the character

[violet bison]

making an array of object types,
which of those does actors belong in?

[dark drum]

All of those are actors.

[frosty heron]

Actors are object that can be placed into the world

so that goes for walls, floor, projectile, vehicle, w/e listed there

every thing you can select in your level is an actor

[south raven]

hey everyone I'm trying to call a Boolean value from my one Blueprint to another Blueprint. Picture I'm sending is the end of my first blueprint, in my second blueprint I want to make if WheelsDone boolean is True, then do something. I'm not sure how can I call this boolean on my second blueprint

[dark drum]

It looks like an issue with your additive animations. The top half is being moved dramatically. It would probably be best to ask in #animation.

[wispy kayak]

Hi, now I can select the index child accordingly. However the previous clicked button still mark as selected, I'm using border opacity render. How to let the system to know the previous button while am clicking the new button.

[frosty heron]

when you create the button assign index to them

for example.

Create 4 buttons
For loop -> For Each button, add index = current index

so you will have button 0 with index 0, button 1 with index 1 and so on

to know which button was selected last, you just store reference to the button

Have Last Selected Button object reference variable in your W_Master

pass the reference to the button when it's clicked via event dispatcher

[wispy kayak]

Thanks its working now

[waxen quarry]

Anyone having an issue in 5.4 where the rotate to normal isnt working? The snapping to surface works but the rotation doesnt change.

[lunar sleet]

Don’t crosspost

[pure jolt]

Oh sorry, its not an animation but an impulse

[rain violet]

Is there a way to set this value in the RigidBody node in all child ABP of the parent ABP?
Like I would like to have a different override physics asset for all child of that blueprint. Right now we just don't use the parent, the behavior is manually copy pasted in all blueprints and that's a pain to edit, especially because they all share the exact same behavior, with the only difference being the override

EDIT: Using ue 4.27

[trim matrix]

can someone help me w figuring out enemies? every tutorial ive seen is melee or fps, and i just want ones u can jump on or use powerups to defeat them

[faint pasture]

Have you made them walk yet?

[trim matrix]

yea i have one walking either from random points in a nav mesh or two set points

thats it

[faint pasture]

So when do you want them to jump?

You will want to use behavior trees probably.

[trim matrix]

i want to be able to have the player jump on them to defeat, or press their spin attack input that rn only plays an animation

or, use a powerup to defeat them

[empty wasp]

why when i change actor location i loose ability to grab it in vr

[sinful prism]

Using UBIK yields this error, I used the package as is and haven't touched anything, do you guys have any idea? It was working yesterday, without any issues 🙂

Is it okay to call a Get DataTable Row node every frame ?

[barren tangle]

hi, there is the node : Load Level Instance.
Is there a node to unload the level instance? i don't find an Unload Level instance

or maybe i have to save the reference to be able to do that?

[mild galleon]

Hello. i have a general question as of, how to approach a system for BP implementation.
I am having a game project, RTS; multiplayer, and i have construction of buildings and spawning units;
as well as units. For being able to save the game and load again, as well as to
clearly correlate health and other attributes to spawned actors (Buildings, Units)
I consider giving each of them a unique ID.
I have looked a bit into methods: Data tables apparently cannot be expanded on runtime,
only changed. That could potentially work as well, if i had thousands of placeholder rows, i guess;
however, seems a bit odd to do.
The other option would be storing unique ID in Maps or Arrays on generation; Now i wonder if i can store arrays inside of arrays
(and if that potentially would become a bit too bad for management).
Each instance of the spawned actors has a variety of properties that i have to save.
If i had arrays only, i would have to have unit ID and then a long list of MAPS where this ID has
a Map for each individual Value of the properties used. Sounds tedious as well.
is there a way to use structs directly, because i have them from my data tables;
or, use data assets that i create on runtime in a certain structure to represent individual unit's properties?
The background is, on my building system, which runs in my master building,
it cannot distinguish between building instances spawned, so the progress update is broken.
Some buildings spawn complete, others never get updated, and its somewhat not reproducable.
Hence the idea of clearly attaching an ID to each individual build progress.
Would you have any recommendations?
Thank you. Sorry, long post.

[mild galleon]

i have used bools in the actors, and then used these as conditions for the states in the locomotion in the animation BP of that actor. It worked and seemed straight-forward.
