[earnest tangle]

delay in a foreach would behave rather erraticly I suspect...

definitely would suggest not using it in any looping macros

you could load a limited number per tick, that would prevent it from freezing

[patent ermine]

Is it possible to do something along the lines of storing all files in an array, and then triggering loading each individually, one after another...for example, load file 1, once its loaded, fire off an event to load second in the array

Or would that behave the same as foreach?

[earnest tangle]

It depends on whether the loading itself is asynchronous

if it is, then it could alleviate the problem

[cerulean venture]

do you need all the files at once?

[patent ermine]

No i dont

[cerulean venture]

you could do lazy loading aswell

load them until you need them i guess

[spark steppe]

bakterhaz you could create a buffer array, and then fire an event which always works off index 0, removes index 0 when done, then fires the event again as long as entries exist

[patent ermine]

Lazy loading? Sorry pretty new to this 🙂

[cerulean venture]

basically just load it until you need it

[patent ermine]

Ok great, let me take some of these suggestions and try to implement. Thanks for the input.

Hey everyone, I'm very new to blueprinting in UE4 and I'm trying to learn how to pick up a box (attached to socket) on collision, and then drop the box straight down on a button press somewhere else in my level. Very basic I know, but I'm struggling quite a lot. The pickup collision works however I can't get the object to drop on key press. Here's what I have so far. Any help/direction would be much appreciated. Thanks everyone 🙂

[dawn gazelle]

Not 100% sure, but I think you may want to store a reference to the carried box on your character, (Your Equip Box message call should have the reference to it) and then move the DropBox event to your character, while making the rest of the code (below) as part of an event or function on your box item that you call from DropBox which is now present on your character.

hey, how do i change color on this blinking material?

Hi, can anyone help me out to call overridden run function of editor utility blueprint on a specific time or event?

I have made a Editor utility object to call it on editor startup but I need to call it at a specific time when I want

[inland arrow]

Hello guys, I've created a material to get a blur effect (thanks to a tutorial). But the blur effect depend on these 3 selected values and I want to set it over time (from 0 to 4 in like 10 seconds) after a trigger, and I really don't know how do that :/

[glad moat]

@dark crow i managed to get it to work on the emissive material like this. but now i need to do it for a light blueprint, how do i replicate the same soft blinking?

(second one is my failed blueprint attempt)

[dark crow]

Well, you can just use the material and create a dynamic material instance and set parameter values if you wanna have some logic with it

[glad moat]

hmm, will have to google that. never used a dynamic material instance

[dark crow]

Basically it just reads a Material slot and enables you to edit the Parameter values inside it with its reference

In your case you could modify Param from a Blueprint

And if you made the 3Vectors parameters too, you could modify Color from a Blueprint the same way

You reference them by their name from the BP

[glad moat]

hmm haha im totally lost

[dark crow]

You gotta call it on the Mesh

Lemme show an example

[glad moat]

basically, the material is for an emissive material, and now i need to do the same blinking on a point light

[dark crow]

Oh so you wanna do that

Just use a timeline with light intensity

Dynamic Material Instance is only useful on Meshes

[glad moat]

ahh okay

so something like this?

[dark crow]

Yeah, you can do it 2 ways here

Or directly provide the values from the Timeline depending on the Time

Or use a Lerp from starting value to Target value with Alpha from the Timeline

[glad moat]

ah, okay. should i use the lerp to get a soft fade?

[dark crow]

You can achieve soft directly too

[void cobalt]

does anyone know why my sounds get quieter everytime another sound plays?

[glad moat]

what should i plug where?

[dark crow]

Lemme show

[glad moat]

amazing, thanks!

[dark crow]

If i want in 5 seconds to go from 0 intensity to 500 then go back to 0

I create 3 keys

This would not be smooth tho so select all Keys

Right click and select Auto

[glad moat]

ahh, ive never keyframed a blueprint like this

[dark crow]

Other way would be like

[glad moat]

is it a vector track you add?

[dark crow]

I added a Float track

Other way is value min 0 max 1

And you can Lerp like this for example

You could even just have A as 0

If you want it to just be off

Still better to use a Variable for it tho for clarity

[glad moat]

amazing! it works!!!! thank you so much!!

now just to sync it with my material

now the light is in the bottom right and i need to sync it with the emission of the torus

[dark crow]

Usually they would be in the same blueprint and use a shared value, or you can eye it and edit the timeline length to match the emissive one

[glad moat]

alright, yeah maybe i could just make another blueprint but with the emissive torus instead?

or which do you think would be easier?

so just replace the light with the torus?

[dark crow]

Time in Material is equivalent to Get real time in seconds in BPs

[glad moat]

how do i get "get real time" in here?

i cant seem to replace "event being play"?

[dark crow]

Basically you want the Timeline to drive the PointLight and EmissiveMat too with Dynamic Material Instance

You can drive the intensity of the Material the same way as the PointLight

[glad moat]

hmm

so i put a dynamic material instance in the blueprint?

[dark crow]

You can decide how to do it really, same BP or different BPs, one for ring and one for light or both in the same

[glad moat]

alright!

i cant seem to get it to work this dynamic material instance, but ill read up a bit more on it

thanks for the help!

Hi! Does anyone know of any blueprint fuzzy string search functionality? or a plugin that does that?

[chrome fractal]

can anyone help me please with editor utility object?

[keen wedge]

Hey, thanks for the reply. I've never created a curve asset, and having tried to following your suggestion I couldn't see anything about inputs or outputs.

In the end I resolved it with math... I need to pass the scale ratio through the entire equation and multiply it at the end.. so I think its resolved now, but would still be interested to know how to make the curve asset work as per your suggestion.

From overcomplicating it, I meant, I just wanted to know what I was missing from the formula/math to make it work, as opposed to creating assets and learning how to configure/use those too, despite it invariably being a better solution than my own.

[sand shore]

oh sure

I see what you mean in that context

[runic parrot]

Hi guys, i'm trying to make an aim system by shooting a sphere trace from the camera ->forward X distance.

for some reason it's not hiting the target, only when it's on the "tip" of the sphere at the end or start it hits

maybe i need to use a diferent trace type?

[keen wedge]

Hey all, random issue...

I've popped a DrawDebugBox into my level to see a specific area. Whats kinda weird is despite the sizes for this being calculated correctly, it is both wider and taller than the sizes set in the Extents.

I removed the calculations and just hard coded in a 100, 0, 100 for the extents and when I measure that I'm getting approximately 120x120?!

The project is using a tilemap and such, anyone know if its likely to be the "pixels per unit" thing affecting this, because from memory, I think they were close to this value... seems a bit of a stretch though...

[runic parrot]

maybe scaling at some point?

[keen wedge]

Yeah, thought maybe so, just not entirely sure where to look for that...

If I want to get a 100x100 square in photoshop, setting the extents to about 83x83 seems to work... but not sure where to look for the issue...

[tawny jackal]

What is a possible explanation for having an actor that is centered in the blueprint editor, but when I drop it in the scene, the mesh and all of it's colliders are far away from the manipulator?

[keen wedge]

If you've moved the components within the blueprint actor, you'd create an "off-set", that would cause that potentially.

[tawny jackal]

I have move some component around, let me see. I am trying to set everything up in c++ ultimately, but am not there yet.

Is there a way to reset position?

[keen wedge]

In Blueprint you'd just set the transform to be 0,0,0 for the sub-components where necessary etc. If you've done this in C++, then presumably you've "set" the transform of those components somewhere, so, removing/changing that would resolve it I guess?

[tawny jackal]

They haven't been touched in code yet.

[tawny jackal]

My transforms only show scale.

[keen wedge]

hmmm... not entirely sure...

[keen wedge]

Do you have anything that is "moving" the main object, and perhaps a reference to a sub-component has been added instead of the root object?

[tawny jackal]

Looking

[runic parrot]

Check on the blueprint where you create the object if any component is not off-set on the transform.
Check also on the world object that you created is there's not relative-absolute modifications to the transform position

[tawny jackal]

This appears to be the nature of the problem.

https://answers.unrealengine.com/questions/18865/static-mesh-subcomponent-in-code-spawns-at-world-c.html

I am not attachto(depracated) or attachToComponent.

[runic parrot]

that could be the problem, there's a few extra steps when using c++ 😫

[tawny jackal]

And you get to shovel through forum posts to figure it out!

[keen wedge]

sorry 😦

[summer bolt]

so how can i cast to an actor i keep trying many things including this but keep failing

[runic parrot]

are you getting anything on the array?

wait

Im dumb

i messed up the array 😄

[livid vessel]

I have the problem that I cant fire my left mouse button every other button works fine.

ps I dont use EnableInput atm so this message is also wired

[obtuse herald]

do you use more than one left mouse button event?

[livid vessel]

no

[runic parrot]

where are you trying to check for the event?

[livid vessel]

in the character

so that's basically all

[dawn gazelle]

Doing a Get All Actors of Class and specifying the class gets you a specific reference to that class, you wouldn't need to cast to BP_SkillPoints as the reference you have is already of class BP_SkillPoints.

[summer bolt]

dw its fine i got it now

[gusty shuttle]

Gotcha, I'll give that a shot

[obtuse herald]

Try and create a new empty map, set it up so your character will spawn and see if the event works.
If it does then you have probably some other actor in your original map that consumes the left mouse button input.

[keen wedge]

anyone know if any camera settings would affect how a DrawDebugBox might end up being rendered?

[gusty shuttle]

[livid vessel]

@trim matrix I mean, JumpPressRemember on the jump, not JumpPressRememberTime. Either way, thanks a bunch man!

Maybe it is because of this. It workes before but now it will not fire on Windows

Yo so, im having an issue where im trying too adjust the amount of force applied too a projectile based off a shooters rotation

And it dosent matter where i aim its always the same speed in the same direction

Not too sure what im missing

[obtuse herald]

Try touch events instead of mouse events

[livid vessel]

sorry im stupid it knows that im on windows

[livid vessel]

you mean disable use mouse as touch?

[obtuse herald]

no, but actually try that first

[livid vessel]

wow thats it

[obtuse herald]

yeah, your mouse probably only fired touch events then

[livid vessel]

jea probably confused of this switching between platforms i think XD

[obtuse herald]

GetForwardVector (of your character) * Force(as Vector3) is what you're looking for i guess?

[livid vessel]

thx man for showing me the right direction 🤗

Thanks man lol

[keen wedge]

I've had a look-see through that and can't find anything that stands out. my project started off as a 2DSideScroller template which I've updated... if I used the DrawDebugBox in mine, it appears larger than the extents I set it at... if I open a new project for the 2D Side scroller template, add the same code for the box... it appears correctly... just dont know where to look to resolve the issue.. 😦

[obtuse herald]

did you change the unit scale in your project?

[frigid ether]

Hey guys, my "Cast to" to my save game object all of the sudden stopped working.
It's returning true that a save game exists, loads it but then the cast fails. Why?

[keen wedge]

I dont think so... although I'm not sure... where can I check?

I added tilemaps and some of the sprites had a pixels per unit set to 128 etc, which is remarkably close to how much it appears to be out... but i think its coincidence...

[obtuse herald]

In Project Settings > Editor > Appearance

[hushed pewter]

One more thing sorry.

When i shoot, despite my ball being constrained too the y axis

It goes infront of

Or behind

[keen wedge]

Dont think I've ever changed any of those... no yellow arrows next to anything to indicate its different from default... will compare to the newly created default project too...

[hushed pewter]

Although when shot down it still interacts wtih the objects

[obtuse herald]

It sure is a weird problem tho

[keen wedge]

same in both projects... doesnt look changed..

[obtuse herald]

yeah then i hoenstly don't know

[keen wedge]

to get a 100px x 100px square when taking a screenshot I have to set the extents to 83 x 83 etc... really weird...

yet the newly created project is utterly fine...

😦

[runic parrot]

still with the 120x120 problem? most likely you are scalling it by 1.2 at some point

check from blueprint and go down from there

[keen wedge]

yeah, still the same problem... cant get anywhere with it... no idea whats going on or where to look... nothing being scaled in blueprint...

not code I've kinda written anyway.

the viewport stuff was because I had hoped to use that, halve it and draw the box based on those sizes... but it didnt look right, and thats when this merry dance began...

[obtuse herald]

You can try to migrate everything from your project to the template and pray that the problem wont appear again, but that's probably a bit too time-expensive

[keen wedge]

literally EVERYTHING I do in UE4 seems time-expensive... I did consider that but then I dont know if there's things I've set along the way that I might need and will then run in to more problems when those settings aren't in the new project...

[obtuse herald]

actually, are you using a orthographic camera?

[keen wedge]

There's a "SideViewCameraComponent" on a CameraBoom in the PlayerCharacter BP... that's set to orthographic...

but from what I can see... its settings are hte same as the one in the template project..

[obtuse herald]

is this your main camera? Because if you change the OrthoWidth then the object's appear as they've changed in scale but you're actually just "zooming"

[keen wedge]

I think its the main camera yeah, I dont have one in the level itself... if I run the game.. there is a separate camera actor in the scene, one that comes with hte game mode stuff I guess...

When I click on it, I just get a black window in the preview... dont think thats in use..

the ortho width of the sideviewcameara component is 2048 in both my version and the template project...

[obtuse herald]

hmm

[keen wedge]

that one gets added like all the other dross I dont need, gamenetworkmanager and gamestatebase and so on... stuff I've not touched etc...

[obtuse herald]

try simulate instead of play and see if the extend is still messed up, if not then it's a problem with your camera

[trim matrix]

Awesome. I was waiting for a good moment to ask my question.
How would i get the velocity of an actor on a spline. Get velocity doesn't work.

[keen wedge]

The size when I select it from the screenshot in photoshop is 103x105 (ish) when I run it in simulate mode... for the 100x100 extents (so closer)...

[obtuse herald]

103x105ish is probably the fov of the editor cam, so i would say it's a camera problem

[keen wedge]

kinda losing my mind here now... was conscious I had the window open on a different monitor.,. brought it back to the main one... used run instead of simulate and now I'm getting the same size as simulate, e.g. 103x105 for the 100x100 square...

I've been a bit rough and ready with the select... but earlier it was like 120x120 for a 100x100 extents...

[obtuse herald]

wth

[keen wedge]

all I want is a box half the size of the viewport in the middle of the screen 😦

everytime I try to do the most simple thing with UE4 its like pins in my eyes...

[obtuse herald]

Try that with umg

[obtuse herald]

are you setting the position of the actor on your spline every tick(or so)? because then you need to manually calculate the velocity

[keen wedge]

its not something I want to see permanently... its part of another problem I was having yesterday.. lol..

I am using eye tracking for moving the character... but I discovered that to get the -1 / +1 axis range (like you would on a gamepad) you had to look all the way to the left, or all the way to the right... because the player was then not really looking at their character it made playing the game really difficult. So I changed some code to make a smaller "detecton zone" which was supposed to be half the size of the viewport and in the centre... but obviously I couldn't "see" it ... so I thought if I put this bloody box in the same place I'd be able to look at the edges of that and then see if my values were -1 / +1 etc.... before my eyes get to the very edges of the screen...

I've just run everything I had originally, about 2 hours ago... taken a screenshot and selecting the debug box is about 10 px out vertically and horizontally, which I have to put down to the 5px thickness of the line...

this is utter nuts..

thats half the width, half the height, and just slightly lower down than the centre of the viewport as its focused on the player character etc.... and is fine!??!

/hot pins at the ready

[obtuse herald]

it's not centerd to viewport, its centerd to the player

[keen wedge]

yeah, I take the viewport size though, and halve it... the camera centers on the player from what I can tell...

it just slightly lower than the actual centre of the viewport...

but thats ok...

the box is the right size...

by spending two hours talking about it... changing nothing... and going insane..

[obtuse herald]

The box just wanted some special attention xd

[keen wedge]

😄

I honestly have no idea what changed/happening/going on...makes no sense at all... almost like clicking on something or viewing a setting has "refreshed" something and its gone "ok, go on then, I've made you suffer long enough, I'll display it properly now.... entire 4.25.5!!!!" 😄

UE4 hates me

Just a little shout to everyone who's tried helping...I really do appreciate it... this project will be the end of me!...

[trim matrix]

Yeah, i'm just having a hard time putting it into bps.

[obtuse herald]

So you want an actor to follow a specific path on a spline but you not sure how to do it?

[trim matrix]

No. I already have an actor following a spline. but i'm tracking the speed of the player and the vehicle (actor) and it using get velocity works fine. but not on the vehicle. Because i know it's tracking the velocity of the vehicle. But the vehicle isn't really moving. It's just moving on the spline. How would i get the velocity of the vehicle using distance/time in the actor's bp?

[obtuse herald]

can you show me how you've implemented the spline follow?

[trim matrix]

https://www.youtube.com/watch?v=bWXI91FdMtk&t=1s&ab_channel=DoubleCrossGames It's actually this video.

Question does anyone know why my FPS character would sink through planes that have collision, has a capsule too this is after setting up a crouch function in the event graph

[hollow zephyr]

On my HUD widget I created a progress bar to show ability charge. I bound the percent variable to my players ability charge variable and the bar is filling up fine, but I wanted to also display the charge % as text over top. However when I Get Percent it returns 0.
Are you not able to bind the ProgressBar Percent variable to a textbox if the Percent itself is bound to something else?

[rough blade]

If I have an array of structs composed of various arrays - how would I add a value to one of those arrays inside the struct? Using the basic "add" or "add unique" doesnt seem to work.

for reference

[prisma stag]

This seems to have worked thanks.

[spark steppe]

well, one is text the other one is float, so i guess it wont even work if the textbox wasn't bound to something

[hollow zephyr]

Not sure what you mean? the float value can be converted to text quite easily.
But the fact remains that the Get Percent function is returning 0, when the bar is clearly filled. I watched the bar go from 0 to 100

[spark steppe]

sorry i was on goose chase, somehow thought that the bar wont fill

[obtuse herald]

do you use get(a copy) or get(a ref)?

[hollow zephyr]

I wish lol

It sits there filling, mocking me 😦

[rough blade]

get a copy

[obtuse herald]

You are basically only modifying a copy of your struct and not modifying the struct directly. Use get a ref to achieve that

[rough blade]

Thank you! - that is going to prove to be very useful

[indigo bough]

Might be missing something obvious, but why can't I destroy an actor (self) using replication?

(Actor is replicating)

The only way I can seemingly get it to vanish (although not replicated) is just destroying the actor with replication turned off. Every other combination of replication events seems to fall flat on it's face

[gusty shuttle]

Quick one, is there a decent clever way to reset a DoOnce inside a function?

[earnest tangle]

make a custom event which connects to the reset pin and call it from your function

[gusty shuttle]

yeah, you can do that in the event graph, but not inside a function (which is where this is)

It's running on a axis event so I need to only call something once if the linetrace hit

[indigo bough]

Can you put the DoOnce outside of the function?

[earnest tangle]

it works just fine this way

[indigo bough]

You can't put a custom event inside a Function zomg

[gusty shuttle]

Top right is where the Do Once is haha

[earnest tangle]

@indigo bough it's not inside the function, the function just calls it which is perfectly valid

[indigo bough]

The function only 'does' as often as it's called, can you not call the function once Chris?

Put the Do-Once inside StickyWall

[earnest tangle]

Ohh sorry you have the do once inside the function? hm well that makes it more difficult

[earnest tangle]

I don't think you can reset a do once inside a function outside of calling the function itself

[gusty shuttle]

Already did something simular, I've been at it all day boys, you'know that feeling where there's work to do but the brain is mush haha

[indigo bough]

Yeah, same here

[earnest tangle]

so you'd need to have some method with just the function call to reset it

[indigo bough]

Why isn't the Sticky Wall doOnce working?

[gusty shuttle]

It technically is, however I have a line trace that, once toughing the wall, allows my character to do a wall jump

[earnest tangle]

if you must be able to have it inside the function and reset it from outside the function, use a boolean with a branch

[gusty shuttle]

Indeed

[earnest tangle]

it's not as "simple" as a Do Once but it would work and you can just flip the boolean from where ever

[gusty shuttle]

Indeed. I have to picture this in my dumb head haha

[indigo bough]

Yeah you could replace the DoOnce in Sticky Wall with a Branch

And pass a bool through the Function

[gusty shuttle]

Ah, true

[earnest tangle]

or a class variable

since you can then just reset it from some other event or function if needed

[gusty shuttle]

I'll give it a shot! Thanks gents!

How do you guys usually explain to people what a blueprint is? First thing comes to mind is "oh, the little nodes and wires that do code" but then the scene and the settings of that scene is part of the blueprint 😐

or am I missing a term?

I usually go with "it's the unreal word for <<prefab>>"

[earnest tangle]

I mean you can define those things in C++ too and you don't explain C++ in some elaborate way either

blueprint is just visual programming I'd say

[static charm]

yup

[unkempt quarry]

how do i solve this error when packaging: error LNK2019: unresolved external symbol

[rough wing]

How can I find the vector 3D widget? This is in the level blueprint

[oak gorge]

hello there,i have a question about a combination of input on vr (one button pushed and one axis moved at at least certain range for make the action) (and the same thing reversed for another action)i have started something like this but im stuck to find a ways to do it ,any idea ?

[sleek pecan]

Are there no conditional breakpoints in BPs?

[static charm]

you can make your own conditions and then break after their met

[sleek pecan]

that seems like a weirdly obvious feature to not have

but thank you for the answer

[static charm]

yeah i agree but eh, its blueprints, lots of missing stuff

[sleek pecan]

@oak gorge your logic seems to be pretty messy there. Your check for the YAxis just doesn't make any sense. In the Greater Than Or Equal To operator you've created, you're comparing the Axis Value to (Axis Value + 1.0). That will always evaluate to false (it can never be bigger than itself + 1)

besides that it's hard to tell even what is happening with your Sequence and Gate

[oak gorge]

yeah the logic is not right ive just started to put what i trough

at term i want to have the combinaison of two button (grip+ a certain movement of the controller axe) which can activate an action

[static charm]

have the button pressed set a specific boolean on pressed and on released

[sleek pecan]

I believe you can set it up so that when you press the Grip button, you then query for the Axis Turn value

[static charm]

the same boolean will then branch open/close the input axis

[sleek pecan]

Instead of listening for the InputAxis Turn event, just call "Get Turn" and compare that value to whatever threshold you want the value to have to go over

It might also be "Get Look Up" instead of "Get Turn" depending on direction

That should work unless you need to check for the player pressing them "at the same time". What I described should work if you are checking for "Did the player press the button while moving on the axis" but that's not the same thing as "Did the player press the button and start moving on the axis at the same time"

[oak gorge]

is more like did the player press the button and move the axis afterward

hmmm can be something like when the button pressed,the axis value is saved and when the saved value + a certain rotation make a branch

[sleek pecan]

If that's the case I think you have a slightly harder engineering task to do

give it a shot!

[static charm]

either methods just described to you will work

[sleek pecan]

Can someone tell me what Disable Input actually does? It seems to do...nothing

It blocks all input events for that player controller

[static charm]

what class is the blueprint? by default generic actors have input disabled already.

[oak gorge]

Can you please be a little more specific about your proposed solution ?

[static charm]

the logic here can be re-made or changed etc

but this shows whats going on.

[oak gorge]

ok i see now

but since is a vr controller the > state will be the same thing ?

[static charm]

you can print string the values and move the controller to see what it is. it probably is like the mouse, not moved = 1.0. move a lot 1.xxx, move a lot other way -1.xxxx

[sleek pecan]

That will definitely work but if you need it to be a check for when they do them at the same time and ONLY at the same time, that's quite a bit more complex

[static charm]

i assumed he meant just same general time, as in holding the button down

yeah otherwise he'd need a timer added to give a few ms window for the player to catch both

[oak gorge]

sorry but that not at the same exact time is push the button and after if the movement is done the action is set

[static charm]

not sure what you're asking

[oak gorge]

was just to clarifying that not the two input action at the same time but one after the other

[static charm]

here the player can press button once, and code will work for 2 seconds before self turning off.

or make it 0.1 seconds for more of what you want

sorry lots of ways to make it work lol

[olive ingot]

Does anyone know if it's possible to attach a Ragdoll to a moving object?
For instance, an invisible ball that bounces and has a ragdoll attached to it, that would in effect follows the ball's location.

[obtuse herald]

Attach componet to actor should work

[olive ingot]

Have you tried? It doesn't seem to work at all for me :/

[obtuse herald]

did you attach the skletel mesh?

location rule should be snap to target

[olive ingot]

Okay you got me on my first step. This actually teleports the skeletal mesh to the location succesfully.

But it does not attach. I suppose I could just repeat this for every frame to make it attach.

[olive ingot]

Oh, btw I should mention. This is just a testing blueprint. There is only 1 "Test Object" on the map. I just set it up like this for testing purposes.

Update. I just tried to repeat it every 0.02 seconds and the mesh just falls to the ground. It only goes to the location initially.

[obtuse herald]

yeah, because it's attached already but the ragdoll kinda does it's own thing

try to attach a bone to the actor

socket name = bone name

[jaunty stirrup]

I have a math problem , i try to place the icone of my character in the right place in the map image of the game, I subtract the landscape position to the player position , but the icone is not exactly at the right place

[olive ingot]

oh I was just going to ask how to get it but you already answered 😂

[olive ingot]

the return value is a string. How do I apply this with blueprints?

*not string, its a name variable

[jaunty stirrup]

Maybe there is something to calculate with the landscape bounds size x and y?

i don't find the calcul

[obtuse herald]

actually, open the skeletal mesh, find a bone that fits your needs, copy that name and paste it in socket name

[jaunty stirrup]

Or maybe there is something with DPI scale

[olive ingot]

It doesn't work. It only goes there initially :S

oh i made a mistake. This socket is for the object i want it to be attached to

[jaunty stirrup]

How to apply DPI scale to my calcul

[obtuse herald]

try to play around a bit with the transform rules and see if one is working

[olive ingot]

nvm. I was mistaken to be mistaken. The description asks which socket i want to have attached to my object. So this should be correct

[olive ingot]

I essentially just need a way to teleport a ragdoll.

I suppose Apply Force is technically a way 😂

[obtuse herald]

i don't think the DPI scale is your problem there

[static charm]

Physics Handle will work for ragdolls but its a pain to quickly setup

[jaunty stirrup]

@obtuse herald The icone is almost at the right place , just decaled

and applied to the movements

[olive ingot]

I take this back. The "issue" I'm trying to solve are replicated ragdolls. I just need them to end up in approximately the same location. So if I could attach a ragdoll to a moving object, that would solve my problem.
Normally ragdolls are very complicated to replicated accurately in UE4.

[obtuse herald]

is your icone anchor set to center?

[olive ingot]

This actually works 😂

[jaunty stirrup]

no but its more decaled than that , when i 'm in a place the icone in the forest ( where character can't go) but the calcul is not so bad because it follow the movements with the same decalage ( multiplied because i divide the vector 2d)

[obtuse herald]

does it also work with the teleport node?

[olive ingot]

By using Set World Location?

[obtuse herald]

yeah

i forgot that the teleport node only exits for actors

[olive ingot]

Oh wauw it does!
Strange... I seem to remember that setting location didn't work.

Thank you @obtuse herald !

[obtuse herald]

Happy to help

[runic path]

Has anyone had struggles getting a startup movie to play ?

[jaunty stirrup]

@runic path its simple

whats 's your problem

[runic path]

wont play

[jaunty stirrup]

I look in my project

the .mp4 must be placed in Movies folder (windows in explorator)

[runic path]

done it

[jaunty stirrup]

and in project setting do that

[obtuse herald]

change the viewport size, if the offset is not the same then it's probably due to DPI scaling

[jaunty stirrup]

how to change the viewport size?

[obtuse herald]

change the window size

[jaunty stirrup]

i try

[runic path]

indeed, that might be an issue as my standalone is a tiny square in 4k

[jaunty stirrup]

icone is in the same place when window is resized so its not a dpi scaling problem

[obtuse herald]

why are you diving by 400 actually?

[jaunty stirrup]

It's the only value that place the icone at the right x position

[runic path]

@jaunty stirrup I have done all the stuff as per instructions and thats why i call it a struggle rather than not knowing how to do it

[jaunty stirrup]

its just for test

normally i divide by 1000 because the map is 1000*1000

i think there is a think to divide or multiply with landscape bounds 2d

[obtuse herald]

can you add a new icon at the landscape actor lcoation?

because i think the map center is not the same as the landscape center

@jaunty stirrup

[jaunty stirrup]

i try

[runic path]

My settings

[jaunty stirrup]

i can't see the new icone

[obtuse herald]

then set the old icon to the landscape position

[obtuse herald]

ZOrder?

[jaunty stirrup]

ok

i look z order

no its zorder 0

i place the old

not visible

my landscape is centered ...

its coordinate are -201600,0 -201600,0

[obtuse herald]

yeah then the drawn map and the actual map locations are offcentered

[jaunty stirrup]

i need to subtract the half of the bounds of the landcsape?

before dividing

the landscape is centered in its size

[obtuse herald]

yeah try that

[jaunty stirrup]

the size is -201600,0 -201600,0 * 2

ok

nothing

i try dividing by the bounds

the bounds are a radius or a diametre

because when i print the bounds its the half of the landscape

[jaunty stirrup]

now i have this

there is no more weird "400"

the icone is at the same place than before

excentred

[rigid marsh]

LF quick help, if anyone can: I'm trying to create a variable with a name array, although all that's available to me is a "name" variable with a single default value. Is there any way I can get a name array?

[tiny meteor]

hi, I have an event which applies a delta to the Z-value of a transform

basically its a slider which moves an object up and down

except, if I apply the delta, then set that as the new transform, the next time it is called it will add it again

whats the best way to do that without wasting memory?

[haughty axle]

hello there guys, have stupid not stupid question, how can i get number of items in array (total amount).. all the stuff works, it gives me right names etc... i just cant figure out how to get the total amount of items in array

[snow harness]

Length node might be what you're looking for

[haughty axle]

@snow harness thx man but lenght node brings bag full list with names of meshes, i am trying to figure out how to get amount in number of items

[hollow cape]

the length node returns an int which == the amount of elements in the array

[haughty axle]

man i double check

[snow harness]

https://docs.unrealengine.com/en-US/ProgrammingAndScripting/Blueprints/UserGuide/Maps/MapNodes/Length/index.html

[hollow cape]

correct concept but wrong node, that's a Map.length() node

[snow harness]

If that's the wrong node, maybe I'm misunderstanding. I use it all the time.

[haughty axle]

yeagh but i am using instanced meshes in array

[hollow cape]

@snow harness The node that you linked takes a Map as an input. We are talking about an Array. it's the exact same node, just a different input

@haughty axle show code

[snow harness]

Oh yeah as far as the documentation, 1 sec

[haughty axle]

wait thats the end of code

[snow harness]

Maybe it's not what you guys are referring to, but this is an example in my own project. Not hooked up in that case cause I was just getting the count.

[hollow cape]

@haughty axle so what's the issue then

[snow harness]

At least the Length part looks good

[haughty axle]

the lenght node gives me names and list then i printstring, i need total count what is in array

[hollow cape]

no it doesn't

[snow harness]

^

[hollow cape]

Look at the length nodes output, it's a single int

show how you are using the printstring

[haughty axle]

man not the names

i just taking what lenght node give

[hollow cape]

can you set up the printstring and show how you are using it

[haughty axle]

yeagh one sec

its now like this, and i trying to count how many are, or i am stupid and he will always gives me the amount of meshes i feed him in (right now two).

now then i stareted to think again i am doing this all wrong

[hollow cape]

ok I see the issu

[snow harness]

Deleted my message cause actually I don't see it lol

I missread

[hollow cape]

what you want is "get instance count"

[haughty axle]

i thought i can do something like, put in for each loop and do counting how many meshes

[hollow cape]

so each Instanced Static Mesh component in that array itself has a number of instances

[snow harness]

Ahh. I've never worked with ISM arrays, so that's never been an issue. Thank you for the info.

[hollow cape]

so what you want to do is pull off the output of the get, then Get Instance Count, then THAT is the number of instances tied to that specific Instanced Static Mesh Component

[steady orbit]

Anybody know how i can change where the cameras pivot point is? No matter where i move the camera it always pivots around 0,0,0

[hollow cape]

we talking editor camera? camera component?

[steady orbit]

camera component

[snow harness]

You could attach it to a camera arm or a child actor, then rotate that

[steady orbit]

Like an fps character

[hollow cape]

yeah generally you would attach it to a spring arm or a scene component if you want to change the relative root/pivot

[steady orbit]

thank you

UseControllerRotationPitch
UseControllerRotationYaw
UseControllerRotationRoll

These are all disabled^^^

The issue is the camera rotates with the capsule and not by itself

I want it to rotate by itself

Keep the capsule stationary when pitching

[hollow cape]

uncheck use controller rotation pitch

[steady orbit]

I said they were all unchecked ^^

[hollow cape]

where did you say they were unchecked

[steady orbit]

Above the video

[haughty axle]

@hollow cape thx man, that does what it says, but i need to do some extra stuff in project, because now i spawn instace meshes and they check for collision before, and if hit result is false then it adds it but if its true then he does nothing... yeagh and now i have to get visible meshes count 😄

[hollow cape]

I don't watch with audio

@steady orbit show code, how are you rotating the camera

[steady orbit]

okay

[hollow cape]

on your up/down, I'm pretty sure you want to be rotating the camera itself

[steady orbit]

i tried but couldnt figure out how

Any tips?

[snow harness]

I don't have access to unreal right now, but you can use the Set Relative Rotation node referencing the camera component. Then take that input float, mulitply it by a float variable you could call sensitivity, then input that into the pitch rotation of the set relative rotation node.

That left right input will go into the yaw rotation after the mentioned math

You can use Make Rotation to change floats into a rotation

Oh yeah, might need to Get relative rotation first, and then add what i mentioned above to it, then enter that into Set Relative Rotation

[chrome wigeon]

To be honest

Why now both UE and Unity attract people with little to no programming experience with visual scripting

Instead of clear text script language that is easy to understand (like something that takes only English and math bases)

[trim matrix]

Can you guys help me out please? I tried making a simple blueprint by following my udemy course but I keep getting errors even though I did exactly what he told

[trim matrix]

I managed to fix it somehow by redoing the whole blueprint but it's not executing the my function code

which is this right here

[turbid shard]

Hello, I am having some troubles with the "Teleport" node, sometimes it fails even if I disable the collision of my dest location. The player sometimes is not teleporting, any idea / fix?

[weary jackal]

teleport with adjusted transform

[turbid shard]

I can't find any node like that, how should i do it?

[dawn gazelle]

Where's your logic that loads your player at the checkpoint?

[gusty junco]

I honestly have no idea where to ask this, sry for that.

We are using customized collision for most of our static meshes, but on almost every restart of the engine the collision disappears on some of the meshes. The fix is to open every affected mesh, untick and tick the box in the screenshot then save.
Any idea how we can make the collision persist?

[earnest tangle]

I've used customs on a bunch and haven't ran into this - perhaps you could build the custom collisions into the mesh itself in whatever 3D program you've used to create the mesh? This way it shouldn't reset in any weird way

[nocturne sundial]

Hey there got a quick question, is it possible to change gravity scale just for specific static mesh component in BP ?

[gusty junco]

I can ask the 3d-modeler if he can do that, as long as it's possible in blender. Thanks for the input
It's so annoying, i just "fixed" every single collision and everything works well in PIE. I tried to package, and all the collisions are gone

[dawn gazelle]

Where are you loading your spawn location from your save game to the Spawn Transform variable?

[earnest tangle]

@gusty junco Check the custom collision bit here for how to set it up in Blender https://docs.unrealengine.com/en-US/WorkingWithContent/Importing/FBX/StaticMeshes/index.html

If you use the official blender ue4 plugin it also can do it for you

[gusty junco]

Thanks a lot, will give this a shot 😄

[dawn gazelle]

Your problem is:

"In the charatcerBP on beginplay, it calls an event that loads the data which contains this code and is supposed to set the player's spawnpoint"

Right now, your game mode starts up, but it doesn't have the spawn transform data until the character is created, but by that point, the character is already spawned, so it wouldn't load it at the position.

Your game mode should probably be handling the loading/saving of where the character is spawning, not the character itself.

You should be able to do it on begin play on game mode or game instance, but the character itself really shouldn't be handling it.

The overlap can still notify game mode or instance that the spawn location should be updated.

[dawn gazelle]

Are you actually spawning in the player yourself at the start of the game?

Yep - Correct :p

Noice

[ruby surge]

IS there a possibility to change the pivot point of a default static mesh like the 1M_Cube but only for 1 copy of it in the component tree of an actor? (I use it a lot for prototyping)

These all use the same box static mesh, but with different scaling

[tidal venture]

https://docs.unrealengine.com/en-US/Resources/ContentExamples/Blueprints_Advanced/2_5/index.html

if both the parent script and the child script each contain a ReceiveBeginPlay event, only the event in the parent script will fire. "
Shouldnt it be the child script that has it fire?

[cerulean radish]

how can i set properties before "beginplay" event when i use spawn actor?

[urban jetty]

Tick "Expose on Spawn" on your variables, then you can set them before they're spawned/in the construction script

[cerulean radish]

oh i see, thx

[urban jetty]

yeah as I understand it BeginPlay in a child will override the parent unless you call the Parent:BeginPlay

[tidal venture]

then the docu is wrong, i ll reporti t

[gusty shuttle]

What's the best way to add multiple keys into a GetInputKeyTimeDown. I know it's a struct, but it seems like I can only have one key at a time.

Now I'm getting this error

It says none, but there is default values, so obviously I'm not understanding this fully haha, anyone care to shed some light?

[dawn gazelle]

Try disconnecting the pins, compile, then reconnect them and compile again.

[gusty shuttle]

Already did that. Now I have a problem where my engine, in the event graph, when I right click my box menu does not show up...ultra annoying. If I move the engine window to my second monitor it works fine, but on my main monitor , after some dev time it won't show

Oddly, if I am doing a screen share, it shows on the screen share on the main monitor. But I can't see it on my physical monitor

[inland cargo]

Anyone know How to remedy a crouch not uncrouching when released in an FPS

[urban jetty]

Doesn't look like your Lerp node is set up right...

[inland cargo]

Arhhh I'll have to check it over on debug the False doesn't seem to trigger on release in the middle branch

[white crypt]

you set your branch condition to be true, so it will always be true..

and as the other guy said, lerp is not set up properly. hover over it and it will explain what value will be used when alpha = 0

same as with vinterp , it will always return your current value instead of target over time

delta time and interp speed shouldnt be 0

[blissful lake]

Hello,

Does Anyone know why i get this error and the character can't move?

I can look around, jump in place and i can even crouch and do other stuff the ALS character can.

I recently started using ALS and imported him on a project i had and added a lot of the stuff my old character could do and the only problem so far is this one, the rest i solved them slowly but it compiles fine and it's supposed to work.

Any ideas? Please and thank you!

with strings i get spamming zeroes from all values, XYZ

[white crypt]

probably your movement curve = NULL

make sure it's set before you use it

[blissful lake]

not really sure how to do that, gonna try looking around and see what i can do

thank you !

[blissful lake]

=0 wher'es that option? on char movment?

[dawn gazelle]

nope on the ALS character

[blissful lake]

yeah but the mesh? skeleton?

[white crypt]

it's a current movement settings struct

[blissful lake]

i can't seem to find it

and i know i've seen it

[dawn gazelle]

In the class settings 😛

err class defaults

[blissful lake]

oh thank you, i've changed it to responsive an slugish but no change, it won't move at all

[white crypt]

in your place i would have migrated the als character to my project and used it as a foundation to build

also double check the gamemode, see if you are using the same settings

[blissful lake]

i just recently learned about ALS and when i saw what it can do i loved it and wanted to use it on my project and learn while i'm at it

i will check game mode and see

[white crypt]

another issue could be that you didn't set up any action inputs

in the als they probably have inputs like "walk", it could be that your project doesnt have any of those, thus why only the camera works

go to project settings - input and compare

[blissful lake]

yeah i did, it was working perfectly fine when i did

then i applied all the things from my old char and had problems compiling for obvious reasons but one by one i cleared all the problems and now it works

i mean, it compiles but not won't move

stangre is that it can jump crouch etc

gamemode uses the same settings

to the Z

[white crypt]

try to see whats happening when you press a button to move, add print strings or breakpoints to see where it breaks

will need to debug it a bit

[blissful lake]

the strings give me 0's , i will try breakpoints and see what i come up with

thank you for the advice

[white crypt]

if it's 0 then either its not being pressed or the scale value inside input settings is also 0

[jaunty stirrup]

Can someone show me how to draw a texture on CanevasRenderTarge2D?

It dosent work

[blissful lake]

scale values are at 1 and i don't even need to press anything before i breaks and shows 0

very weird

it's spamming 0 and can't find the source

[tacit shard]

how do you pass arguments to an event dispatcher in blueprint?

i have event dispatchers to handle giving and taking damage, but i need to pass the damage amount

yeah but where do i set its inputs?

all i seem to be able to do is copy a signature

ohhhhhhhhhh

that was well hidding

hidden

[white crypt]

@trim matrix hover over it and see what it says

[dawn gazelle]

If that's the decrement node (--) it takes the variable as a reference rather than the value of it, so yes, it should set the variable to the decremented value.

[tacit shard]

i didnt see that, thanks:D

[white crypt]

https://prnt.sc/10pzzl2

[timber cloak]

how do you block moving with linetrace?

i have moving box mesh but they go through each other

i see. i was assuming linetrace has collision, thus, can behave as stopper

because volume like sphere etc appears to behave the same

[earnest tangle]

traces are just "queries", they query for collision information

[timber cloak]

i see. curious, how do those default actor or pawn block movement then?

[earnest tangle]

They have a capsule collision component

[timber cloak]

capsule is query too, right?

like traces

[earnest tangle]

collision components can be simulated

but with the characters the character movement component handles it if I remember correctly

since it's not physics based

[timber cloak]

meaning? Just don't get the simulated and not physic based etc

[earnest tangle]

objects that are simulating physics will collide and bounce off things based on what the physics engine says

[timber cloak]

i see

[earnest tangle]

those that aren't won't, but depending on whether their collision is set to "physics" or "query and physics", then they have a physical representation which the physics engine sees

[timber cloak]

but those you mentioned are not physic based, so how come?

[earnest tangle]

characters aren't physics based because they have their own movement component that handles it, since having characters follow the physics engine rules can make them difficult to work with

basically the movement component queries the physics engine information using traces or collision information from the collision capsule

[timber cloak]

interesting

[tacit shard]

how exactly does actor overlap work? say i have a static actor and a character set to overlap, when the character walks over the static actor, should both the character and static actor call the overlap event?

or is it only the actor that is moving that calls it?

[earnest tangle]

it gets automatically handled by the engine, you don't need to call anything

[tacit shard]

yeah i know, i want to know how the engine calls it, should it be called for both when one actor is static?

cos i have this setup now and the overlap appears to only be fired on one of the actors

the character

[earnest tangle]

iirc overlaps will only get called for the side which has its collision set to overlap

[tacit shard]

they both have it set to overlap eachother

im creating a damage component, when the owning actor overlaps another, it checks if the other actor has a damage component, then if this damage component can take damage and the other can receieve it, deal damage to the other

so when 2 actors with damage components overlap, they should apply damage to eachother if they can both deal and receive damage

but it seems the overlap event is only fired on my character

[faint pasture]

Stopping is handled by whatever is doing the moving. A block doesn't stop something at a low level, just reports a block. If the thing doing the moving doesn't handle it, it's like it never happened.

Using physics, the physics engine handles it. Using CMC, it handles it.

[gusty shuttle]

I'm having a issue where if I use GetInputKeyDown, it records the keyboard fine, however, if I start using the controller, it continuously counts upwards, even if there is no input. Am I using the wrong method for finding out how long a thumbsticks been moved?

Any idea for a better formula to calculate player input for thumbstick?

Naw, I run a print and it's 0.0

I thought so too but noppers

Yeah, if switch on the fly between keyboard and controller, it counts the keyboard fine from 0 to however long I press. However, if I pick up the controller and press a direction, depending on how long I have been in the instance for, it gives me like 20 seconds instead of 0

Anyways, found a cheap solution for the fix

bhahaha I mean, based on frame rate and stuff, but it'll get the job done

[void cobalt]

can someone help me pls

i have had this issue for a very long time and i do not know how to fix it at all

i have a bullet tracer for my linetrace gun

and i want the tracer to dissapear on impact with something

and yes i tried the obvious

it didnt work

i really do not understand why this doesnt work

[fossil linden]

@void cobalt you mean a projectile?, if yes, your collision should be in top as component / replace the default scene root with your collision

and make sure to use the right collision channel

[void cobalt]

what do u mean it should be in top as component

how would i do that

[fossil linden]

drag and drop it on the default scene root

[void cobalt]

default scene root..?

[fossil linden]

wait a sec, i open my engine

[void cobalt]

you mean this?

[fossil linden]

your collider should be on the top

thats what used for hit collision

[void cobalt]

yeah the sphere

right?

[fossil linden]

yes, its a sphere collision

[void cobalt]

yeah i have it

what do i do with it

[fossil linden]

drag it on the defaultsceneroot

it should ask then if you want to replace the defaultsceneroot

[void cobalt]

where is the default scene root lmao

you mean drop it into the event graph?

oh wait

thats what u mean

yeah ok i dragged it in

what now

now it looks like this

sorry im really tired brain very slow lol

[fossil linden]

yes, now its should be working

if you collision channels are correct

[void cobalt]

its not working no

i dont even know what correct is anymore

ive tried so many combinations

you mean this right?

[fossil linden]

you need to enable collision query and physics

[void cobalt]

still doesnt work

[fossil linden]

yeah because its overlaps, you should change the object type to projectile

or block on world static and dynamic

[void cobalt]

there is no projectile option

ill try world static

didnt work

ok wait

i blocked world static and dynamic

and it kinda worked

it destroys when it hits walls

but it doesnt destroy when i hit enemies

[fossil linden]

then check your enemys collision type

and if it blocks your bullet

the best thing would be to create a new collision channel

[void cobalt]

ok i think i got it

blocked physics body

and now it destroys on enemy hit too

thank you so much

[fossil linden]

no problem

[void cobalt]

you have no idea how much ive struggled with this for so long

no one could find a solution lol

and ive asked ALOT of people

[fossil linden]

well, thats some unreal stuff you learn only if you do stuff with the engine on a longterm period

if you have other question you can ask me anytime (if i have time to anwser :p)

[void cobalt]

well actually there is another problem now

when my enemies die, they ragdoll

but the bullets affect the ragdoll

and they shouldnt

so their bodies just end up flying across the map

[fossil linden]

yeah because i guess you block physic bodys?, the best thing you can do now or late to make a list, which collision channel react with each other

its a bit confusing first, but its just locial

[void cobalt]

oh i fixed it

when the enemy dies and turns into ragdoll, it changes collision type to pawn instead of staying as world static

which my bullets will only destroy after hitting world static or physics body

[fossil linden]

yeah you can do that, but you should create your own collision channels for some states, a good thing would be a player collision that you can damage only the player or only enemys and dont have to worry if both get damage

in that way you have more control what should be happen

or if someone cast area affects what should be only affecting your player etc

[void cobalt]

yeah ill probably do that in the future

[plain pewter]

How can I clone a component with all its properties in a blueprint construction script?

I want to create three Spot Light components with "Use Inverse Square Falloff" set false but there's no way to set that property in blueprints so I'm going to set it on a "template" component instance and just copy that three times.

[earnest tangle]

Can you not use a "Add Spot Light Component" and then click the node to se the value there?

[plain pewter]

You can't set the "Use Inverse Square Falloff" property in blueprints for whatever reason. You can get, but you can't set.

...and ofc I can't use SpawnActor from some other custom spotlight blueprint for this, because I need to run it in the constructor 🙃

Why the heck is "Use Inverse Square Falloff" hidden, this is so 🤬 annoying

[dawn gazelle]

It's set to blueprintreadonly, so you can only set it on the right. My guess is that it's not something that's supposed to get updated during runtime.

[plain pewter]

I don't quite get that because AFAIK it can be set in C++ at runtime with no issue. Maybe on certain platforms it's iffy... but there are so many ways to shoot yourself in the foot with Blueprints anyway, why remove this footgun...

[timber cloak]

thanks for the reply.

[blissful lake]

Hello,

does anyone know why this error is popping?
my character can't move
i just started using ALS and implemented some of the stuff from the old character and it compiles perfectly so far
but the char won't move , can jump and crouch and all that
also the camera works fine too

I tried strings and breakpoints, it comes as zeros spamming and i can switch between walking and running with a key you can see the switch if i hook up the string to the beginning.

It breaks at the beginning of these nodes "Update Dynamic Movement Settings", it seems like for some reason the character doesn't receive any movement data.

Please, any help with why could this be a problem... and thank you.

[gusty junco]

Hey again, sry for the ping.
We've been trying to get it to import the mesh with collision for ages now, with no luck. Can you see any immediate errors?
Tried with and without "auto generate collisions"

Naming convention: (Tried many variations)
MeshName
UCX_MeshName_01

Also tried with the send to unreal plugin, but it still auto generates the collision to something else. :((

[earnest tangle]

That looks like it should work as long as the collision mesh is convex

keep in mind you need to export all the meshes in the file, in some cases it might not export everything into the fbx

[timber cloak]

very curious how does one mimic the block for the simple box's movement using linetrace only.

[earnest tangle]

you'd have to keep linetracing on tick or something and if it hits something that you want to block, then you need to stop movement

[dawn gazelle]

We've already told you about the errors - that's because the Curve isn't being set. If you've put the curve in, have you checked what those values are being set to?

[timber cloak]

as in mimic the other class's move

[timber cloak]

i see, thank you

[blissful lake]

The curve should work fine cause it's the same as the ALS provides and it worked fine before i hooked up the things form my character, but now i can't resolve the why it won't work. The stuff i hooked up involves only picking up weapons, creating a vector to interact with line of sight, interact with F and not much more. Nothing involving movement cause i knew ALs char had already all the movement i needed.

I know some of you answered but after hours(it's been a few hours already) and i'm still stuck here, i'm out of ideas.

I also added firing

[dawn gazelle]

Have you checked to see what the values are being set to though? If they are being set as expected by what is in the curve, then the problem doesn't lie with the code you're showing.

[gusty junco]

Hmmm, when reimporting the FBX to blender/Maya we get both meshes, so that should be good.
Could it be that the collision mesh does not meet some criteria?
This is how the collision mesh looks, in my mind it should work as a convex mesh

[earnest tangle]

Yeah not sure. Try just making it a basic cube and see if it works then

[gusty junco]

Will do, thanks for all the help

[gusty shuttle]

Did you guys ever have the problem where when you jump, your second jump is higher for some reason? Or like you can have 3 proper jumps but the 4th launches you higher for no reason (there is a reason but I don't know why). Any keywords or tips?

It has something to do with velocity or acceleration I think?

Only happens when I wall slide

or rather, when I wall jump sorry

[pastel garnet]

How do I NOT make a struct replicate?

Everybody in the game is taking after the last client who joined's hunger values.

I thought of making a copy for each person but how?

Give me a minute for dinner, sorry anybody wanted to help!

[dawn gazelle]

Where is it that you're storing and setting the hunger and thirst values? You can think of a struct as a "variable container". So if you store the structure in your character, then each character would have their own hunger and thirst values, much like they would have their own HP and the like. If this is a multiplayer game, then you definitely want these values replicated from the server to the specific character, otherwise players will be able to cheat. It's more likely that you're doing something that is setting the values on all characters rather than the character that is supposed to have their value changed.

[dull sequoia]

Could someone help me figure out the math for orbiting an object around another moving object at a fixed distance? I've been trying to understand this but all the solutions I find only work on one axis and I need to rotate around all 3 using WASD input

[prisma stag]

Hello, I have a conveyor that uses get overlapping actors. However when I have the collision inside of the main static mesh, it moves by itself ingame 😂. I know the reason is because its colliding with itself and wants to move itself, but I have other objects in a class that I dont want to move either but they are of class BP_BasePickup as seen in the Class Filter. Is there a way I could get everything of BasePickup but phase out stuff of another class?

[trim matrix]

No collision on basemesh and a collisionbox in the conveyor. i cant remenber exactly it was a few years ago.

https://youtu.be/XxBOoWY5P5w

[split spoke]

Hello I'm having this problem right now and I believe this is the right channel, so if anyone can explain to me exactly what are the mistakes there or what the problem in general is it would be great. I'm kinda new to blueprint so I'm not really sure from those messages alone. I'm trying to get the ai to deal damage to the player when a certain animation plays out, so what's the best approach?

[dawn gazelle]

Casting is a means of getting a more specific reference. For example if you had an "Actor" reference but wanted to be able to access functions within the "ThirdPersonCharacter" blueprint, you would cast that actor reference to ThirdPersonCharacter. You need to have a reference to something to feed into the cast's "Object" pin.

[prisma stag]

I would like to keep the collision for the basemesh on though. I would just like to have the filter class, not get a certain class.

[pastel garnet]

I store the structure in my character, yes.

[bright nacelle]

i have a single component that when i use on multiple blueprints i run into an issue where when i rebuild the component all versions of it become linked together. IE i edited a variable in one bp and it will effect the others. However if i delete the component form the bp and re-add it i can individually re-edit them all again. what is the solution?

[fossil linden]

sounds like you edit the default values of the struct?

you should use 2 structs, ones that holds the realtime data, and ones that define the max value

[bright nacelle]

hmmm ok ill try it thank you

[trail condor]

Sorry if this is a silly question, but it seems like there's a way to get a World Context Object automatically inside a blueprint library, is that true?

like if I just add it as an argument to function, does it get passed in automatically without changing the signatures?

[tight schooner]

@trail condor there's a Get World Context node

[gusty shuttle]

Hey guys, is there a way to chill the velocity acceleration down?! haha My dude get's bouncy fast if we call and jump (LaunchCharacter based on impact normal)

[trail condor]

RIght but I think I've seen something where you add a parameter to the function, and unreal automatically gives you one, without changing the node at all

[graceful hamlet]

I must be imagining it, but it seems like UE4.26 blueprints don't work as well as 4.24/4.25. Breakpoints, variable values showing up, struct breakout info. It seems like the debug functionality of blueprint is going backwards

like in 4.25, if I have a blueprint on overlap execute a print, and I put a breakpoint there, it hits it, then I see the print. 4.26, I see the print, no breakpoint executed.

Like this will print false - never even pause at the breakpoint

[livid vessel]

something is wired with this code it will save and load during a game but when I close the game the array gets set to none 🤔

[sand shore]

wow did optimization passes get added?

[graceful hamlet]

Same here

On 4.25 this same super simple example will pause twice

[sand shore]

oh no it's just the debugger being bad as usual

[graceful hamlet]

It's actually gone backwards, too - 4.24, you could get outputs from pins, then 4.25 you had to go all the way back to where they came from, then 4.26? You want values? Screw that

it's made catching stuff like typos sooooo much harder. Has anyone found a fix yet?

[dawn gazelle]

You can't save objects in save games.

[livid vessel]

bruh

how do I save then my instanced static mesh components?

[dawn gazelle]

You don't. You save the values that need to be saved and then reconstruct them when loading.

[graceful hamlet]

Yup

[trim matrix]

I did the collission for the conveyor in Modo and a separate collision (the belt) in Unreal. I cant startup that file anymore is was version 4.14

[livid vessel]

bruh thats a complete Buildingsytem. Will be funny

[graceful hamlet]

You save the data about the objects, then on your respawn you import the stuff you need

Good place to use structs and datatables and such, then you can just save the stuff you needed to create them in the first place, so you can shortcut it

[livid vessel]

I can save Datatables?

[graceful hamlet]

like "bob's wood pile" might be a struct for woodpile with size, mesh, how many logs it has, transform, etc - then on reload, you spawn those values

Nah, you save deltas for datatables

so that you don't have to overwrite every single value, you have a default

[livid vessel]

the problem with instanced meshes is that they do not give you data back

[graceful hamlet]

yes, understood, an ISM/HISM is built procedurally

but you have to store what you need to recreate it. The seed, etc

(if you intend to recreate it precisely - obviously not for stuff like leaves or whatever)

[livid vessel]

I cant save this part as a non Object😭

[prisma stag]

What is modo? Yea the problem is I only want the collision to react to a parent class, but not to a certain child class.

[graceful hamlet]

I can barely see that, but it looks like you're just plugging in a transform?

[livid vessel]

yea but the problem ist that only the location wont tell me which block it is

[graceful hamlet]

so you need to store your block type and transform

when you make it in the first place

[livid vessel]

and also the block gets set by a Grid that can change

[gusty shuttle]

I have a deadline and I need quick assistance as to fix this launch velocity issue. The wall jump LaunchCharacter seems to be using some acceleration and it's being a pain in my neck. Any help would be much appreciated

[livid vessel]

okok yea I will try it XD 🤗

[graceful hamlet]

Nobody said it was easy 😄

But yeah, that's the up/downside for arbitrary builders/spawners, you gotta really dissect and track everything

[trim matrix]

Modo is like Maya, Blender its a modeller. @prisma stag

[livid vessel]

Sometimes I really hate Ue for saying ha you cant save or ref objects before XD

[graceful hamlet]

I have no idea how people have the patience to code stuff like Valheim. My hat is off to them

You can always try some of the save game plugins, some do a good job of that

I found most were just more annoying than doing it myself

[livid vessel]

I think I will die on my way to make a simple save system XD

[livid vessel]

Do you have any specific in mind? Maybe for saving objects

[graceful hamlet]

Ok - so I'm guessing nobody has figured out how to fix the blueprint debugging issues yet?

The "new" ones, at least

[graceful hamlet]

I tried "easy save load" once, that might work for you

[dapper laurel]

hello everyone

sorry to interrupt

[graceful hamlet]

ok well seeya folks 🙂

[livid vessel]

I have this one

[dapper laurel]

but,has anyone had an issue with unreal when using a controller? (PS4,PS5,XBox one)

the issue is it seems to be constantly getting an input axis value which is incorrect.

if up is positive x and down is negative.
right is positive y and left is negative y.

it seems to be constantly receiving a value of (+1,-1) so keeps running diagonally

any ideas as to why it only occurs on certain machines and not others? already made sure the input setting are the exact same in the editor settings

[livid vessel]

and I hope it will do what I want it to do XD

[livid vessel]

Hopfully this worldsave will work would be nice and give me a lot more time for other things

[hollow zephyr]

Does anyone know how to edit the character movement so it's more responsive?
I started with the First Person template and I find that the movement response isn't instant, like there's a small maybe 0.25 to 0.5 second ramp up period before the character moves at full speed. I want more of an arcade-like feel. Instant movement response when you press WASD

[graceful hamlet]

oh dude. I found it. It's on the end of the toolbar in the blueprint window: Set this to your current BP

then suddenly it begins to work as intended again

larger view to make it easier to find

[livid vessel]

yea of course you have to select every time because it wont remember🤦‍♂️

[graceful hamlet]

Well OBVIOUSLY hahahaha 😄

Why have it work as it has for the last 15 versions? Silly us

[sand shore]

yes you can, believe in yourself

[sand shore]

the point of a breakpoint is to break at that point! regardless of what I say I am or am not debugging

[sand shore]

you can tune acceleration values to be stupidly higher than your max speed

that's basically it

[hollow zephyr]

I'll give that a shot, thanks

[gusty shuttle]

So yeah

How would one solve velocity inertia

When I wall jump and have momentum, my dude springs into space

[hollow zephyr]

you could try removing it as soon as you touch another wall, set velocity to 0

[gusty shuttle]

Oh?

I kind of do that

[prisma stag]

I see.

[hollow zephyr]

I might suggest a straight "set velocity" on the movement component

[gusty shuttle]

So this is the normal that gets set, which then is supposed to nullify the velocity in the blue comment, yet it does not

I could get it a shot, set it to 0,0,0

@hollow zephyr There is definitely no bounce back now haha, now im just stuck on the wall and slowly move down. But it's something haha

[hollow zephyr]

So you're taking the rotator, and rotating, then multiplying the result by the jump magnitude, and then removing the current velocity from the rotator

actually, not from the rotator but from the result of the float-vectory multiplication

[gusty shuttle]

I'm feeling about half past stupid after hours of trying to figure this out

[hollow zephyr]

So that's not actually modifying the underlying velocity data members, unless I've misread that

[gusty shuttle]

Perhaps, So what do you think I should do? Deadline is at 4:30 haha

[hollow zephyr]

School project?

[gusty shuttle]

Personal, but I'm with a team and I promised results

[hollow zephyr]

Ah

[gusty shuttle]

Well setting the velocity to 0, stops the inertia sling back which is good, just need to find a home for it

[hollow zephyr]

if there's no input within X milliseconds after touching the wall, you probably want it to start falling at the speed of gravity

you could always get the velocity, modify the Y/Z component (which ever your project is using as "up") and then set the velocity

that should help with boucing up off the screen, but should keep the rest of your momentum and might give better results

You could modify it to 0, or dampen it by 50, 75, 90%, whichever feels best

[gusty shuttle]

I'll give that a shot! Thanks @hollow zephyr

[hollow zephyr]

Good luck!

[gusty shuttle]

Dude, it fixed it hehe

Thanks man, just had to make a new event/function to stop velocity once I touch the wall. I have NO clue why I didn't think that would work, but it did!

[hollow zephyr]

YW 🙂
Glad it worked out just in time for your deadline haha

[pastel garnet]

How do I NOT make a struct replicate?
Everybody in the game is taking after the last client who joined's hunger values.
I thought of making a copy for each person but how?

They are stored in the player character by the way.

it is a multiplayer games and each character should have their own value but shares one of the client's.

[dawn gazelle]

Replication is the process by which a value is transferred from the server to a client or vice versa. If you have the struct stored on your character then each character should have their own sets of values. You definitely want the struct to replicate from the server to the appropriate character, otherwise the players can end up cheating. You are probably setting the value incorrectly as each character should have their own copy of the values and the server should be handling the values.

[pastel garnet]

Right.

These are the variables in my character

and none of the hunger variables are replicated

nor does the server handle them

How do I make each character have an own copy of the values?

[dawn gazelle]

They already do if those values are stored in your character blueprint.

[pastel garnet]

Hmmm

howcome people are sharing the same values?

I must be setting it wrong

[dawn gazelle]

That looks ok.

[pastel garnet]

Strange

[dawn gazelle]

What is calling the "Hunger Struct Set" function?

[pastel garnet]

These are the structs

Hold on

It is StartFunctionTimers

[dawn gazelle]

From what I can see there, you have it running HungerStructSet every .1 seconds, so I imagine it would hit 0 fairly quickly.

[pastel garnet]

Yeah

Debug purposes

And I think everytime it hits 0, the clients won't share the same values anymore and it'll be back to normal

[dawn gazelle]

The clients don't share any values if these variables are not being replicated from the server.

[pastel garnet]

Oh

Weird

because mine do

[dawn gazelle]

No they do not. It is impossible. Every time you spawn a character, it would receive a fresh copy of all default values. Clients cannot set values on other clients, and if you're not replicating the values, then other clients will not receive the values that the other characters have.

[pastel garnet]

Right

My server inherits from the client's values

Everytime the client loads on the hunger values reset to the client's

[dawn gazelle]

That's probably happening as you have the Update UI function within the character.
So what is happening is:
Server is started.
Client 1 joins the game.
Client 1 has a character spawned with fresh values on the server which replicates to Client 1.
"Begin Play" for Character 1 is fired on the server.
"Begin Play" for Character 1 is fired on Client 1.
Character 1 begins to update their hunger value, thus updating the UI on the local machine (Client 1)

Client 2 joins the game
Client 2 has a character spawned with fresh values on the server which replicates to Client 1 and Client 2.
"Begin Play" for Character 2 is fired on the server.
"Begin Play" for Character 2 is fired on Client 1.
"Begin Play" for Character 1 is fired on Client 2.
"Begin Play" for Character 2 is fired on Client 2.
Character 1 begins to update their hunger value, thus updating the UI on the local machine (Client 1 + Client 2)
Character 2 begins to update their hunger value, thus updating the UI on the local machine (Client 1 + Client 2)

[pastel garnet]

Woah

[dawn gazelle]

So every character that would be spawned is updating the local UI.

[pastel garnet]

Ah right

[dawn gazelle]

So it's overwriting itself.

[pastel garnet]

so they all share the same local UI but has different values?

[dawn gazelle]

No

Your character should not be driving UI updates.

As each character is then driving UI updates.

[pastel garnet]

Ah okay

do I drive UI updates in the widget itself?

[dawn gazelle]

Haven't slept well the last few nights so my thinking is a bit slow... You should be able to do this instead.

[pastel garnet]

Ah okay, I'll try that when I reload UE4, thank you!

Get some sleep too

[summer bolt]

So I have a question So for save files you need to edit the game instance, 1st question is there anyway to do it without one, second of all Can I use multiple game instances? Sorry if this dosent make sense

[dawn gazelle]

You don't need to edit the game instance for save games. The nodes for save games can be called in lots of places.

[summer bolt]

Would an actor be OK?

Also where are the save files saved

[dawn gazelle]

As far as that goes, there's only 1 Game Instance ever.

It all depends on what you're trying to load/save and when you need it. ie. Doesn't make sense to handle loading/saving on a character if you wanted to load that character's details first before spawning it, as you'd have to spawn it first before being able to access the saving and loading of it.

Save files are stored in <your project folder path>\Saved\SaveGames

[summer bolt]

What about when the project is compiled 🤔

Into like an actual game

[unkempt quarry]

Should I be worried about this error?

[sand shore]

yes, you're creating a widget on the server probably

[jaunty stirrup]

How to make UE4 recognize the gamepad?

[unkempt quarry]

I assume that's because i created in the level blueprint?

[dawn gazelle]

Release builds are under C:\Users\<windowsusername>\AppData\Local<UE4 Project Name>\Saved\SaveGames

[summer bolt]

👍

Thanks alot

[fierce birch]

Trying to make a animation to blend with another animation? But I want the top half to play once and stop at the end, how would I do that?

[sand shore]

and without a role check

also I misspoke you aren't creating anything, you're just trying to

it doesn't make a widget, that's actually what the problem is

[unkempt quarry]

The funny part is that it still creates the widget, but just gives me that error after

[dawn gazelle]

That's because your client is probably creating the widget. Begin Play fires on both Server and Client.

[unkempt quarry]

Should i create the widget in the character bp?

[dawn gazelle]

Personally I like to handle UI within the player controller. The real issue, as Lambda has pointed out, is that you're not doing a role check - you basically don't want the server to try and create the widget which it will basically try to do on any Begin Play that exists if that's where you're trying to create it (ie. doesn't matter if it's on begin play on a character, controller, or the level) - use a "has authority" node and connect the create widget node to the "remote" path.

[void cobalt]

hello can anyone help me

i want to make a progress bar widget

for a reload

but all the tutorials are overly complicated

all i want is for the progress bar to finish in the same time it takes to reload

[void cobalt]

ok

[split spoke]

I see. Thanks a lot

[tidal abyss]

hello! Im looking for some help with a "math problem"

I want to get the direction of a target considering the player rotation

basically I want to make a damage indicator. I found some answers on ue4 forums but then I saw a node, which I have never seen, so im stuck there.

this is the node that I cant find on ue4

[astral estuary]

dot product?

2 vectors in, 1 float out, in layman terms, "How alike are two vectors"

[tidal abyss]

Ohh

it works!

Thank you!

I was a bit confused because of the "=" symbol there

[astral estuary]

[unique fox]

If one has a Notify tick, but wants to execute it untill i get a hit from the trace inside How would you approach that ?

It seems play once and checking if the character is playing already an anim dont work

[olive ingot]

When two character collide (run into each other) how do you make something happen just once?
When a clash is triggered it's triggered on both characters (twice). How do you make something happen just once? and still make it repeatable

[tight schooner]

@olive ingot There might be a deeper collision issue, but to answer your direct question, one way is to use a Do Once node

and have some condition (e.g. a simple delay) that resets the gate

[olive ingot]

Thank you very much. I was also thinking about that one 😉
