blueprint

[dark crow]

Nu

If you click the uuh

Semicircle line whatever in the Variable

You can change it in an Array

[wraith bay]

ohh

got it

[dark crow]

Yup

Then click the eye on it

[wraith bay]

This you mean

[dark crow]

Yeah

After you click the Eye, if you click the Button in your level, you'll see it exposed on the Instance

[wraith bay]

Wait dont I have to link this array to something

I link it to destroy?

[dark crow]

Yeah, instead of GetAllActorsOfClass use that

[wraith bay]

Hmm isnt destroying them

[dark crow]

Yup

Click the button in your Level

and go into Details

[wraith bay]

Still gives me pending kill 😦

[dark crow]

Show me the Details of the button

[odd ember]

when you press the button, you could loop over that array

that way no pending kills

using a ForEachLoop

[dark crow]

Yeah that's fine

But yeah, ForEachLoop may be a good idea

[odd ember]

inside the loop, you can also double check that they are valid

triple double safety check

in case there's another button that also destroys these traps

or really, anything that destroys them

[wraith bay]

How would I add this foreachloop

[odd ember]

it's a node

[dark crow]

Drag from the Get of the Array

Type ForEachLoop

[spark cliff]

i have a blueprint that stores a player character variable
upon traversing the map at speed i can get stutters and such, and through print nodes i can see the variable drops out of memory from a stutter.
anyone know how to work around this or store more permanent variables?

[wraith bay]

ye

[dark crow]

Yup yup

Here's a sample

[wraith bay]

Ohh

[muted halo]

Is it possible to export a movie sequence from blueprints?

[wraith bay]

What does "is valid" do btw?

[dark crow]

Checks if it actually has a valid ref

[wraith bay]

So if its in the world?

[dark crow]

For example if it was already destroyed, it fires IsNotValid

[wraith bay]

Ohhh

[odd ember]

pending kill or not existing is not valid

[dark crow]

So does nothing in this case

[wraith bay]

So this is cleaner than the get all actors of class, because it's more precise rather than generic?

Like, it enables me to place more traps

[dark crow]

You can control what traps you want the buttons to destroy

[wraith bay]

Or control their behaviour better!?

Yeah

cool

Thanks a lot

Makes a lot of sense and it helped 🙌🏻

[rough blade]

For those who have made vehicle building games - what did you find to be the best system? 1 actor, 1 actor with child actors, or other?

[native willow]

IIRC I did it by having each part being a separate actor and had a special plugin written that automatically instanciated all of those

[tired mantle]

hello guys , is there a way for me to let the main camera of my fps game to not render specific lighting in scene

[hardy merlin]

I'm getting some very strange behavior with a particle effect I was given by my artist. In preview, the particle fires towards positive X correctly, but when spawning it in-game if I aim at a wall the particle is reversed

So it fires backwards.

I've debugged the normals and rotation and can't find anything wrong with them. Is it something weird within niagara?

[tired mantle]

cause iam trying to make the game dark for the player but there is also light in scene so other players can see in light

[odd ember]

you have to change the direction in niagara afaik (or expose it per instance). but it's definitely more of a #visual-fx query

[rough blade]

Any chance I could get access to that plugin?

for a fee of course

[native willow]

a friend of mine will post it on marketplace in some time

[rough blade]

any idea under what name?

[trim matrix]

How to structure a Game Feature plugin that gives user an ability to spawn a new type of Actor?

[somber quail]

anyone know how to fix this problem im trying to rotate a object along the x axis uses the mouses location but it wont work ik the mouses only uses x and y but is there a way to make it use y and z

[lucid lynx]

I'm confused by what you're asking. It looks like you have X plugged in to rotate as you move the mouse while Y and Z are locked at 0 and 90 degrees. Wouldn't you just need to plug in Y and Z instead?

[somber quail]

no that makes it move very weirdly

here

that black orb thing is the mouses location

i was just seeing if it worked dont ask

but im trying to get that gun to point towards it

befor the game was top down

it worked fine

but now that it is side on

it stoped working

as the mouse moves along X and Y

i need it to move along X and Z

[trim matrix]

hello, is it here that i post this? im trying to make a photocamera in a vr game. so u can actually take pics and it saves like phasmo. how do you capture a picture like that? is it witha 2d scene capture?\

[maiden wadi]

@somber quail What Axis is your game along? What is left and right?

[somber quail]

left and right is x

[maiden wadi]

Well, that wouldn't matter so much.

Well, would a little.

[somber quail]

ok im rotating it on the Y now it changed a few things but isnt working as well

it is a big buggy

it is rotating now

[maiden wadi]

Basically what you need to do is set pitch. Then choose side based on whether the mouse location is + or - X

[tepid forum]

@somber quail Shouldn't it just be breaking the transform and pugging Y into Z?

[maiden wadi]

Pitch is from straight up to down, but it is independent of facing. So you also need to choose the facing(Z in Rotation) based on the mouse direction in world X

[somber quail]

this is the closest i can get to slightly working

[maiden wadi]

Your Yaw should pretty much always be 180 or 0. If your world goes left = -X and right = +X

Then in that case, Right should be 0 Yaw, left should be 180 yaw

[somber quail]

i dont overly understand how to do that tho

[maiden wadi]

I'm off. But I would start by using the LinePlaneIntersect Origin and Normal function. Use it to make a plane at your character's location, facing +Y(Towards Camera), and project the mouse onto it. Then you can convert that to character's local space by getting character location and doing MouseLocation-CharacterLocation. If new local vector is +X, set Yaw to 0, if -X set yaw to 180. Then you might be able to FindLookAtRotation the pitch from the same local vector.

The lack of resources on player controllers is killing me, why does this bring up an error no matter what I do I just can't assign a player controller to a pawn and make it work

[tepid forum]

there's no player1controller?

[sand bloom]

I can use things like getplayercontroller from id to remove the error but that still makes it work wonky with multiple characters

[sand bloom]

I'm just using get player controller from id now

there's no errors but inputs don't work

Not sure why the player controller isn't working correctly and I can't find any resources on how to do this

I just want to get a few player controllers and assign them to pawns so you can control them with some gamepads I don't know why this is acting like this

For some reason player 2 works but the input is all wrong because I press move once and it just won't stop moving even though the character bp itself isn't the issue so I can only assume the issue is the player controller somehow

[tepid forum]

I don't know

[sand bloom]

Nvm I managed to make player 2 work

it's just player 1 not working now

progress..

lol

[tepid forum]

either input setup in settings problem

or maybe execution order problem

[sand bloom]

hmm i'm not sure how that could be

I could try doing the player 1 stuff last and player 2 first I guess just to test

i'm not sure how the order could be responsible for this

well

damn

I don't know why this helped

I literally just played a sequence down

and for some reason it worked

🤔 so uh thanks

i'm very confused but glad I am getting inputs now for some reason

i've watched this old video and i have something to ask. and this video is old so no one will answer me there
so i'll ask it here xd
"watch it first"

so..
Anything H will say D will do the opposite
D is just trolling

Its just if A do B and if B do A just to prove her wrong

and there is still no meaning of this problem
H will say the right thing but in this problem
we gonna do the opposite just to prove her wrong
no one can abuse this to make an algorithm that will run forever
cuz this time the algorithm will be inside H
so H can say what D will do and there is no Bigger D to do the opposite this time

even if a human is doing this he wont get it right, if he says halts it will run forever and if he says run forever it will halt

i know there is something that i got wrong and thats why im asking, they wont offer 1m$ for this if its this easy
sorry for the bad explanation

[trim matrix]

Hello. I am aware of how to make AI go to a RANDOM location, but is there a way to make it go to a SET location? If so. how?

[fiery swallow]

Type in a vector in a reachable nav mesh bounds and watch it go! @trim matrix

[trim matrix]

yeah but i mean can't i just assign a object reference and it feeds its position into a vector?

[trim matrix]

^

[fiery swallow]

Yeah just get the location of that object or simply get a reference of the object and plug it into target actor

Assuming you are using ai move to

[trim matrix]

Ok so let me ask this

I want my ai to have moments where the navmesh just stops. So like there's a scene I was gonna do in unity where the character looks back, a creature teleports behind him, and he starts walking towards the player, then because of the force of the footsteps, the floor under the player breaks and the creature teleports down to the basement where the player is falling. Is this possible in UE5? Sorry if its a stupid question

I even uninstalled Unity because to get pathfinding to work there good you have to code your own and i dont feel like using THAT version of navmesh

[tepid forum]

if it's not dynamic, animate the positions in timeline

[trim matrix]

What do you mean by "dynamic"?

[tepid forum]

Does it need to figure out which path of many paths is the the best way to go? Or does it just need to go from point A to point B on a set path?

[winged sentinel]

Hi I need help replicating this code, any help would be greatly appreciated https://blueprintue.com/render/9we2xhxm/

the latter

[solar dawn]

can someone explains to me what do these mean. For context, one of my asset straight sent me to another map while it supposed to decrease my player's health

[deep cove]

There are many different choices with lighting. I can see what materials are too complex, or what mesh is too heavy.
Is there are lighting mode that shows what BP is using the most CPU?

[deep cove]

When it says 'none' it means you did not set a variable. If you are casting to a ball, and then reference that ball variable later in your BP, it will give this error. You can get around this with'is Valid?' node. It will ask if the ball varibible has been set. If not do... blablabla.....

[solar dawn]

i see

[light token]

How do I move a texture over the x and y axis in a material blueprint?

[faint pasture]

offset the uv in coordinates

or if u wanna animate it use panner node

[light token]

like this?

it's not working this way

[deep cove]

try 0.3 not 100

[light token]

Ah awesome it's moving now

Thanks a lot!

[deep cove]

R = Left to right. G = Up Down. (positive number slide the texture up). -.5 to +5 should be the max you ever need to use. Anything past that, and you are touching the edge of your texture. I used -.28 0 +0.28 to shift between 3 different textures on a sign.

[native willow]

probably smth along those lines

[spiral bison]

So I'm making a 2D RPG, and at the moment I have the attack system in place, but I'm trying to stop the player from being able to spam attacks until the animation is finished and a small amount of time has passed. Is it possible to ignore an input if an animation is playing? I mean I am doing that already I guess, but I'm having a weird issue that I don't understand fully. My character is getting set to their Default animation when an invalid attack is detected, instead of just not accepting it as valid.

[atomic salmon]

Double check you entry logic immediately after the input

Usually you would check if it is NOT attacking then set attacking and run the attack

[spiral bison]

I'm a indie dev and I've just started learning, this is my first ever project so I'm sure that a lot of my stuff is wrong.

[atomic salmon]

Yes no worries, part of the learning curve

[spiral bison]

What do you mean by entry logic?

[atomic salmon]

You get from the player the input command to attack

First thing, you check if you are already attacking or not. If you are already attacking, nothing happens until the attack has finished.

If you are NOT already attacking, then you set IsAttacking to true and play the attack animation

At then end the delay resets IsAttacking to false so you can attack again

So the problem seems to be in your first branch

[spiral bison]

Yeah I have that working fine. The issue is that it's setting my animation to the default, which is blank so my sprite disappears when it returns that I am already attacking. It doesn't let me attack again until the delay is done.

The attack still goes through

It's overiding the animation for the attack with another animation when it receives an input when IsAttacking is true.

[atomic salmon]

Yes that is because the condition on the first branch triggers if you character stands still

[spiral bison]

That's not standing still, that's a check for if they're airborne

[atomic salmon]

Ok

Do you have any other code which is running in parallel? Tick Event?

[inner rose]

Hey,I did something accidentally and my viewport split into 4. Does anyone know how to turn it back to normal?

[atomic salmon]

Ok sorry, I see now that you have the branch out of false. Didn’t see it before. So that seems right indeed.

[spiral bison]

This is my event tick logic

[atomic salmon]

Click the little window icon on the top right of one of the viewports

You may not see it in full, but I can spot it in your pics

[atomic salmon]

I suggest you do some blueprint debugging by keeping your BP on screen while you play

If the flip book resets there is something which triggers that

[spiral bison]

I found it. waaaaaaaaay out in the void of my event graph I had a random input action call going into a flipbook update

This is what was going on.

[inner rose]

Thanks,I will try it.

[deep elbow]

i've spent a few days trying to figure this out, and a bit stumped, anyone played the Room games? trying to recreate something similar to their circular motion controls.
eg. use mouse to rotate an object, like a screwdriver, using circular motions, mimicking the turning of the screwdriver. anyone got any ideas the best way to do that, i need to work around the findLookAtRotation behaviour of pointing directly where the mouse is because that snaps the object to a rotation and it looks pretty bad

[gritty adder]

Heya, does anyone know a way to save a modified dynamic material instance, to a regular instance into content browser? I'm guessing something like create asset, but i can't construct a factory in blueprint.

[earnest tangle]

Not sure but you could always look at what values you assigned into it, and create a material instance with the same parameters

since static instances can be saved as assets

[gritty adder]

But i can't create a material instance in blueprint, since i can't create a Factory.
I think i have a workaround now though, using duplicate asset, and using a premade instance of the material i want to copy

[spiral bison]

Alright guys. I have the attacking logic all done and dusted, but I have a system I want to implement and I'm not sure how to go about doing it. I want progressing through the combo to be reliant on two conditions.

1 - The  animations only go through the combo if a valid hit is detected so that if you are just spamming it will just play the first attack every time otherwise.
2 - If there is enough of a delay in the attack inputs, even if a valid hit is detected it will still reset the combo.``` I can't find much info about these kind of conditions online, thought y'all might be able to point me in the right direction.

[tame tiger]

Hi guys someone know why Blend using variable causing Anim Notifies to stop firing?
its kinda strange cuz anim A notifies are working, but not B

[spark steppe]

what's the blend weight of A and B?

iirc they only fire over a certain threshold

[bright frigate]

Quick question, why are there two essentially duplicates?
E.g. I converted a point light into a blueprint so it has the root as the bpself and nested under it is a pointlight component, so it kinda makes sense, but I'm still kinda unsure if there is more to it, if there is a slight difference in behaviour with respect to something else I haven't considered

[tame tiger]

im blending default pose and "work" animation with notifies.
if work animation is default animation (goes straight to Output pose) or is A animation in Blend notifies are running.
But if its B animation in Blend - 0 notifies

[earnest tangle]

@bright frigate if you have two components it will list them both when searching for nodes. If you only need one, just delete the other component

[bright frigate]

ok so both will do essentially the same thing right

[earnest tangle]

If they are both point light components, yes

[bright frigate]

it's just how by default unreal made the light into a bp

[earnest tangle]

That only has one point light so I'm not sure why it would display two

[bright frigate]

yea I didn't mess with anything just clicked convert to bp and it chose to make it a subclass of point light in the list, I just clicked ok

[tight schooner]

Here are two loose, untested ideas in my head for how to approach that. If you have a way to convert the mouse location from a pivot to a rotation (lookat works I guess), then all you need is an offset -- upon click, subtract the lookat rotation from the original rotation to get the difference and save the result to a variable, and then you'll have a useful offset that you can add to the lookat output.

Another idea is to, each frame, get the difference between the previous lookat result to the current lookat result. And then you'll have this running delta rotation that you can use to offset the object you're rotating on each frame. You could also potentially keep track of revolutions this way, e.g. a screw that needs 6 twists to lock in. You might run into issues when you cross a 180-deg threshold (e.g. 177°... 179°... -179°... -177°). I don't have an elegant solution off the top of my head for that. Probably have to check if the delta rotation exceeds some threshold, and when it does, add or subtract 360 to get the delta in a reasonable range.

[peak whale]

If I select an actor in the World Outliner and open the Level Blueprint, I don't see any options for it when I right-click; dragging and dropping it does nothing either. Anyone have any idea why that might be?

Okay, turns out I was editing the persistent level BP, not the sublevel BP for the sublevel that the actor is in.

[mild flare]

Hi! I am working with UE4 and using BPs, I have an issue where I override the characters mesh (player choose from Team A, Team B or Lobby) so its displaying another mesh by choice - the issue is that for some reason ragdoll (simulating physics) only works on the lobby mesh which is using the ue4 mannequin - I used "Set Skeletal Mesh" do get the result. Do I have to use something along with it so the death animation (just ragdoll) works?

[wraith bay]

In my game I have this room, and I want the background music's volume lower, leading to a pause, when I enter the room, and when I leave the room, I want it to raise the volume and continue, is this achievable?

Idk if I plained it properly

[spark steppe]

you may need to update the physics asset if you use a different mesh

[spark steppe]

yes thats possible

you would use two triggers like a collision box to your room, the one closer to the room triggers the volume lowering, the other one the raising

or just make one collision box which covers the whole room, on begin overlap you would lower volume, on end overlap you would raise it

[wraith bay]

Okay thanks!

[mild flare]

thanks alot! I was importing the the meshes without setting up the physics asset

[deep elbow]

thanks for the response

[deep cove]

Hopefully a quick question:
I know how to communicate from parent to child and get a reference.

How Do I communicate from the Child to the Parent?

Currently I am having the parent use tick to check a bool in the child actor. It's dragging my fps.

[restive oracle]

Does anybody know how to create a new directory? When searching for 'Make Directory' (https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/FileUtils/MakeDirectory/) in the blueprint editor nothing pops up

[earnest tangle]

A single parent checking a value of a child in tick really shouldn't have much of an effect... either way, you could use an event dispatcher in the child. You can then bind an event in the parent to listen to it, and only run the logic when the dispatcher is called

[velvet token]

That function should be available in a plugin that you can find in the Plugins tab (called Blueprint File Utilities or something like that)

[restive oracle]

Awesome, thanks a lot

[rancid quartz]

Hello, I have a small question about Gameplay Statics and Blueprints.

It appears that GameplayStatics as a class is not available in Blueprints. So, where should a Blueprint developer keep globally relevant data? My first guess is inside the Game State, but I'm not sure.

Any advice would be appreciated.

Cheers.

[gentle urchin]

I think gamestate is appropriate.

[rancid quartz]

Okay, thank you.

[worthy frost]

well context is important @rancid quartz

you have GameMode (Server only in multiplayer), GameState (replicated to all clients), GameInstance (Local only on all clients and server).

PlayerState (specific for each player in the game)

[harsh kayak]

Is there to not spawn actor if out line trace range

[rancid quartz]

Thanks, Kaos. I guess it's a little confusing because it seems like what would be in one place in C++ in GameplayStatics is distributed over several places in Blueprint, eh?

[worthy frost]

not sure what you mean

GameplayStatics are just static functions

that can be used anywhere

just like a Blueprint Library BP.

[rancid quartz]

Oh... maybe I'm showing my lack of experience. I thought it was common to keep global variables (the quintessential example being Gravity) all in the same place. And I thought that place was GameplayStatics. I guess it takes a bit more thought than that.

Does anyone know how to make an in game camera. Like in phasmophobia where u use a camera to take a still image that u can look at elsewhere? Im trying to make a camera. I already have the 2d scene capture that displays itself on the screen of the camera.

But idk how to take a still shot of what is looking at and how to look at it later

[native willow]

you need to capture a specific frame into a second render target for a captured photo while using the first render target for camera view

[trim matrix]

How do you capture a specific frame into a second render target? You make a new render target and then you set render target I know. But how do I just make it that specific frame? Because I set render target and it was updating it every frame

[native willow]

there is a function, just replace render target, call Capture smth smth, (I dont remember) on the component, and replace redner target again

[trim matrix]

Ohhhh that's smart. You set that render target to not capture every frame. Basically put the film in, flash it with that image at that moment, then take it out and put the other film back in in a way.

[native willow]

emm, you want your redner target component to capture every frame if you want to use one component

[trim matrix]

OK so in the photo camera actor. There's a 2d capture scene cam. The screen has the mat of that render target so you can see what your talking a Pic of with the cam. Right?

So then hit interact key, flash goes off, then what? Off of the 2d capture component. What would I do?

Sorry I'm new to this relatively

Should I have a second 2d capture component? One that doesn't capture every frame and just have the one that does every frame for the live screen?

[native willow]

you have your scene capture component which captures to the first render target that you then use in a material, when you take a photo you replace a redner target with a second one, call component to capture (because you want it to happen right now) the image ends up on your second redner target, then replace the redner target on the component to your first redner target so it will still update the material

the photo ends up in your second target

and you use 1 component

[trim matrix]

OK I think I get what you mean. I'll have to test it out and see if I can get it to work.

[native willow]

if you want to have more than 1 photo you will need an array of render targets and before taking a photo, you will have to create a new one

[lament trail]

anyone know how i can connect these nodes?

[lament trail]

Different approach - is there a way to make the static meshes non instanced? i dont need them to be

[bright frigate]

I've noticed that if I have lights set to visible, but they are way out of view (i.e. let's say I'm above ground and lights are underground), they affect the framerate. Why is that? Shouldn't they be culled since they are being obstructed by geometry completely?

speaking of lighting, RTX GI looks great ... alas it only works with HDRI so /fail for me lul

[lament trail]

unfortunately these objects are created automatically from FBX import

[bright frigate]

bruh I first got into game engines way back with Trespasser from 1998, that thing you had to unload and load things literally 10 metres away from you because of obvious reasons but I was always fascinated by it 😄

It's not using the regular RTX raytracing

at least from what I understand

more of a Lumen-ish hybrid approach but without the insane performance hit of full blown rt

true

[lament trail]

Thanks.. its given me an idea

[bright frigate]

just disabling the underground lights that I can't see has literally boosted my framerate to 2x lol

and those lights don't even have shadows enabled on them

AND I have a 3080 ...

pretty crazy

from like 70 fps to 250/uncapped

[deep cove]

ZOMG I am still having an issue with getting the child to talk to the parent.
My issue is that the child (LockA) is trying to set a variable (a bool called Unlock) in the parent. I have several locks on different doors, and some door have more than one lock. Having the parent (door) control everything is easy. On construction is sets the variables for all the children and marks them as lock 1, 2, 3, etc. But then constantly checks (using tick) to see if the variables in each child have changed (from Locked to Unlocked... bool). This is killing my fps. So It would be nicer if the child could send a message to the parent, but unless the parent is hard coded, I can not figure out how to do this. I can cast to a parent if I know the parent is DoorA or DoorB, but I don't know how to cast to something unknown. The locks are used on different style doors. GetParent gives me a name, but I can not figure out how to attach this to anything to get it to call an event, or change a variable in the parent.

[earnest tangle]

Yeah use an event dispatcher as I said earlier

@lusty elbow Pointers point to where an object is stored in memory. If it's invalid, then it isn't pointing at a valid object. To make it point to a valid object, you need to create that object first. For widgets this is often done with the CreateWidget node, then use the blue return value on that to populate your pointer.

[lusty elbow]

Ooooh! I see it now. Thank you so much!

[bright frigate]

ok comrades, I have successfully got my day night cycle and streetlights enabling and disabling smoothly at the proper times.
Now I want to add a delay so that each light may start at an ever so slightly different, random time than the other like in real life (which happens due to age of the light fixture, the electronics and maybe even grid layout/distance, a light routed longer being activated slightly later, or its sensor of the sun at a different angle or dusty or whatever determining its different activation time)

So, shall I use a regular delay node, or a retriggerable delay?

for anyone interested how it's set up

[spiral bison]

Alright guys. I have the attacking logic all done and dusted, but I have a system I want to implement and I'm not sure how to go about doing it. I want progressing through the combo to be reliant on two conditions.
Conditions :
1 - The animations only go through the combo if a valid hit is detected so that if you are just spamming it will just play the first attack every time otherwise.
2 - If there is enough of a delay in the attack inputs, even if a valid hit is detected it will still reset the combo.
I can't find much info about these kind of conditions online, thought y'all might be able to point me in the right direction.

You can see the basic concept, I'm incrementing an int to track the combo, and then resetting it at the end. But I'm not quite sure how to implement the logic for the timing....
I should add, that I am a very new game dev, this is my first project. So I'm probably doing a lot of things inefficiently.

[nimble raft]

ok - im frustrated with a really stupid problem.
I've got a blueprint class (based on actor). it has a defaultsceneroot in it.

Then I have a child blueprint class of ^. It contains a Sphere static mesh (beneath the inherited defaultsceneroot).

Why cant I replace the DefaultSceneRoot like this (construction script of the child BP)

it throws no errors, and flatly doesnt work (runs, and when I inspect the instance in-world, the DefaultSceneRoot is still there).

[maiden wadi]

@nimble raft Inherited components aren't really meant to be replaced. If you're replacing components in subclasses, your hierarchy plan needs a rework. for instance. If 199 of your classes are going to have a scene component, and 2 a sphere, then you need a base class that has none, and then a child of that with a scene component, and then your 199 classes can inherit from that and a second child from the no component base that that has a sphere, which your two sphere types can inherit from.

[nimble raft]

@maiden wadi so, my real goal here, is to have an empty parent BP, and have several different shape child BP. Importantly, the child static meshes need physics on .

This is my problem - with physics on, the child mesh moves around as I collide it - but the Actor (and the DefaultSceneRoot) stay put.

I need the Actor / parentBP / DefaultSceneRoot (which is not simulating) to follow the simulating child

hence me trying to replace it

[maiden wadi]

Out of curiosity, is there any reason why you don't just replace the scene component with a static mesh component?

In the parent I mean. Parent can set it to null. Children can set it to whatever shape they want.

[odd ember]

this kind of thing requires more advanced logic, either as a state machine or a behavior tree IMO

[nimble raft]

@maiden wadi interesting, that would work I think. However - it doesn't really answer the baseline question - why didn't that bp photo above work? like it silently fails... "its not meant to" <- can you elaborate?

[covert swan]

Would this be the right place to post a question about nativization?

[spiral bison]

Would it be easier to remove the hit logic, and make it just the timed window?

[odd ember]

you should look at how each attack may have a state, e.g. FirstSwing, SecondSwing etc.

and have each state perform different logic

then you can also make a SwingMissed state

that could act as a reset potentially

IMO think about how the states would correspond to the beheavior in real life, and go from there

[maiden wadi]

@nimble raft When your actor instance is created. You create two pointers. One to a SceneComponent type, another to a StaticMeshComponent type. Then using those empty pointers you create two objects. A SceneComponent and a StaticMeshComponent, StaticMeshComponent is attached to SceneComponent. Your hierarchy is all set up. Then you come along in ConstructionScript and say that the pointer being used for SceneComponent should point to the StaticMeshComponent. You haven't actually done anything to the components themselves, you've simply changed what it points at.

[odd ember]

THEN you can think about what and how each state executes logic

[spiral bison]

Yeah I'm a new dev so I'm not very experience but I'll take a look at State Machines and see if it will workfor what I need. 😄

[odd ember]

if you're new, always start small IMO

[nimble raft]

@maiden wadi ah ok. I thought it was equivalent to the c++ where you literally set RootComponent. Am I right assuming there is no BP available Actor:ReplaceRootComponent or something like it? I searched a bunch and didnt find one.

[maiden wadi]

Not seeing anything. I imagine to stop designers from breaking complex hierarchies. 😄

[covert swan]

Is there any way to force a blueprint function that returns a bool to nativize as a return value and not an output parameter?

One nativized asset is trying to read it as a return value, while the function is being nativized as an output parameter

[maiden wadi]

Maybe setting the bool as the first return.

But realistically nativization is largely a waste of time and effort. You'll spend less time and get a lot more mileage out of learning some rudimentary C++.

[odd ember]

louis 14'd

[lament trail]

When I drag multiple static meshes (2 x spheres) into my scene at the same time they both end up with the same world location (as shown by the XYZ widget). Why is this? I would expected world locations to be different because they are clearly in different locations!?

[covert swan]

I'm a C++ dev, this is a large project that we are trying to "easily" squeeze some additional performance out of and thought that was a simple way to achieve that. Guess we will have to start porting blueprints to source then :/

thanks

[odd ember]

???

[maiden wadi]

I'd be too terrified of what the nativization would do to my code. 😄

[covert swan]

yeah, just seeing how it can f up something so simple already put me off tbh

and bye to nativization I guess

lol

[odd ember]

when you drag actors... that haven't been assigned a world location yet... into the world, you expect them to have different world locations?

[lament trail]

the fact that I have dragged them into the scene - surely this gives them a world location?

[odd ember]

so you're moving actors in the scene... and they move to the same world location, not keeping their offset?

[lament trail]

thats not really it - After I drag them in together, i dont want them to move anymore. I just want to get their individual world locations i.e. sphere 1 and sphere 2. They both report the same location though. I guess this could have something to do with the FBX file they came from. Sorry if this doesnt make sense!

[odd ember]

where are you asking their world locations from?

and what locations are they reporting? 0,0,0?

[lament trail]

this is how im getting the spheres and getting their world locations

it prints the same location for both spheres

[odd ember]

are they part of the same actor?

[lament trail]

Ive tried looking for a relative, local, offset etc

[lament trail]

they are separate actors in the scene

[odd ember]

try GetActorLocation

[lament trail]

ive tried that... same issue

[odd ember]

could it be that the root components are in the same position, but the spheres are offset inside of their actor?

[lament trail]

the location equals this, no matter what component i select

[odd ember]

try clicking on the arrow next to absolute location and set it to the other option

and see if it still is the same

[lament trail]

i tried that too. its the same values

Its bonkers! where the heck is this offset coming from?!?! 🙂

[odd ember]

try with two different actors

and put them in the same positions as the spheres

[lament trail]

they have different world locations - as i would expect.

it must have something to do with the source of the static meshes - the FBX file. They are referencing something I cant access to get their world location

Thank you for trying to help... been trying things for a few hours now!

[odd ember]

you might be better off asking in #graphics

then

[lament trail]

i will get my question tidied up first... its not easy to explain!

[nimble raft]

@maiden wadi thanks for your help, I realized I could just use a variable to drive the Static Mesh in the component, and do away with the subclasses altogether 😉

[late cave]

any other way to get info from the current level? (ultimately, I want to create a soft object reference from it...)

[odd ember]

not in BP AFAIK

this is what I've done personally

but that's because I can ensure that DT is available from the project settings... which requires cpp to setup

[bright frigate]

Is there a way to change the type of light (e.g. point or rect) to use for a blueprint? As in, the way you can set custom mesh in the construction script. I can't seem to figure out for type of light because a light is not a mesh it's a type of component or something

[earnest tangle]

The lights are specific kinds of components

so if you wanted to change the type of the light, you would have to add a different kind of light component

[late cave]

Haha, neat... thanks, I think I'll do a variation on that 🙂

[bright frigate]

@earnest tangle is there a way to expose that so I can drag and drop it?

I tried object reference or soft reference but I don't really have an idea with components

[maiden wadi]

I use a GameInstance Subsystem for that currently. Keeps track of the loaded level, stores the data via GameplayTag. GameInstance has static data I can use to look up levels or data related to levels via the tag. System also handles my loading screen stuff.

[earnest tangle]

To add comps in BP's you have to use the appropriate node, such as "add point light component"

they all get their own node like that

[late cave]

https://issues.unrealengine.com/issue/UE-60933

WTF Epic!?

They really don't care about blueprints, don't they?

[earnest tangle]

looking at the github PR it sounds like there may be some technical or design flaw with the UWorld refs

[maiden wadi]

To be fair. Level handling really isn't meant to be a designers job most times.

[late cave]

Right, because designers love shit like this? 😝

[earnest tangle]

What are you even doing with that?

[late cave]

trying to stay sane is what I'm doing... but it's difficult

[bright frigate]

but is it possible to swap out which component is being used by a blueprint the way you can do with a static mesh?

[earnest tangle]

you can just add the type of component you want to use instead of hardcoding the component in the component tree

[odd ember]

where do you input your master level list?

[earnest tangle]

beyond that it gets a bit tricky

[bright frigate]

so will it be a case of just setting the point light disabled and the other enabled something like that

[odd ember]

yes

[earnest tangle]

just don't add the point light at all unless that's the type of light you want

I mean disabling it would also work I guess but not sure why you'd want them both

[odd ember]

same

seems unnecessary

[harsh kayak]

Can we check that if line trace is not hitting any object i tried to print string but nothing shows up . It only works on success.

[bright frigate]

well originally I converted the point light that I used for my streetlights. I thought I'll later add ability to change the type of light so I can reuse it elsewhere.

Meanwhile, I already have like a spotlight elsewhere. So different light. However, I want the exact same logic available (like responding to changes in game time)

[odd ember]

the cast may fail

[bright frigate]

basically I want to reuse as much as I can

[odd ember]

in which case you dont get your print string

the branch should be before the cast

[harsh kayak]

Oh

Thanks I should check it right now

[harsh kayak]

it works thank you so much for quick answer

[odd ember]

if it's an issue of future proofing, you can always come back to it

the creed still goes: make it work, make it neat, make it fast

not make it fast, make it work, make it neat

as many people do

[bright frigate]

no I definitely make it work first

as I said, I got the streetlights working and now I'm looking at ways to reuse it for other types of lights

but I didn't realise that it's a different thing for components

[odd ember]

I don't really see a point in changing lights per asset necessarily. if the whole street light, including the mesh and light, is the asset, then where would that be reusable?

[bright frigate]

There's no mesh on the light, it's just a light

[odd ember]

so... you wanted to save a light component and switch it with a different one with no regards to the mesh?

[bright frigate]

there's no mesh 😄

it's just a light

I was hoping to make a blueprint which I can select type of light component so that I can place it wherever I want that kind of light-logic to be

[earnest tangle]

Just make a scene component be the root component for it instead of the light

then you can just have one of the light comps added to it

I mean that seems like it should work?

[bright frigate]

e.g. my streetlights have a nice bit of logic for switching on and off at random times depending on time of day. I have a place where I want to use a spotlight instead but instead of copy pasting the logic it'll be the same BP

[earnest tangle]

alternatively you could create an actor component which contains your light adjusting logic, so that you can add that component to other light related actors

[odd ember]

if it's like a tool for picking different lights (although I fail to see where it would be used), you can use an enum in the construction script to spawn compnents attached to the root, depending on the enum type

whether this is actually faster than picking out a light from the components drop down combo box is anyone's guess

[bright frigate]

well if it doesn't make any significant difference I'll just go with making the spotlight a BP and copy paste the logic there too

but that means adding yet another node at the end of the tick which I was hoping to avoid, although that may not make much of a difference either

[faint pasture]

Don't get too infatuated with inheritance.

[bright frigate]

if I could have changed just the light component then I guess it would be part of this array

[odd ember]

IMO the smartest thing you could do if you're doing it in regards to turning lights on depending on TOD

is using a subsystem that the lights self register to

the subsystem keeps track of the TOD and calls the lights when they need to switch

[bright frigate]

ok I understand the English part of that 😄

the logic for keeping track of whether to switch on or off is within the light BP

[faint pasture]

I would just make a TimeOfDay interface and have some central entity pass it to the sun/moon and all other objects that need the time

or have each entity get time from a subsystem or other entity

[bright frigate]

my sun BP keeps track of all the seconds passing. That "update sun" event is calling the event in the light bp, which checks if the seconds are so and so and whether to switch on or off

is that similar to the sub system being talked about?

the behaviour I mean

[odd ember]

a subsystem is like a manager

it automates the process quite a bit

and prevents weirdness

you can have roughly the same logic with a spawned actor in the level

[bright frigate]

sounds like multiplayer useful stuff

[odd ember]

nah

I use subsystems for saving, I use them for AI

weather,

whatever you need really

[faint pasture]

Subsystems are great because you can globally get them too

[odd ember]

ToD seems like a perfect candidate for a subsystem

[faint pasture]

ya if ToD is a big deal, make it a subsystem for sure.

[bright frigate]

well every tutorial on subsystems seems to be on multiplayer related topics

something to do with steam and steam parties

[faint pasture]

That's just the OnlineSubsystem which is one subsystem already in the engine

Subsystems are like components on an engine/world level

[earnest tangle]

Subsystems are C++ only tho so you're gonna have to delve to that

My game tracks time of day in GameState because it's easier to keep it there for stuff like savegames :P

[bright frigate]

ahhhhhhhh

[faint pasture]

In the meantime you can replicate the same functionality just by having ToD "live" in GameMode or GameState

[bright frigate]

well considering I haven't touched C++ in at least 4 or so years ... gonna have to skip that 😄

probably 6 actually

[odd ember]

game mode is even an actor... so it could be a component on gamemode, if you want separation

[faint pasture]

Really the only difference would be something like

Get GameState
Cast to MyGameState
Register ToD Listener

vs

Get ToDSubSystem
Register ToD Listener

[bright frigate]

well considering the size and scale of my scene, I don't really need to do these things

so I suppose I'll just jank copy paste the bp lol

[odd ember]

important to note that game state is flushed between levels

[bright frigate]

erm so, why are these last two not affected by the same logic? All the others turned on

during a simulation the array has 17 total items in it, why is it ignoring these two?

[lost wyvern]

Is there a way to make billboards render behind geometry in the editor?
I am making a tool in the construct script using a billboard as an icon, but when it goes behind geometry you can't see or click it again.

[odd ember]

material billboard -> custom depth mask

[bright frigate]

ok seems I needed to put a foreach loop for the update event

but the question is why was it working for all the other lights without the for loop 😂⁉

[odd ember]

are the lights self registering?

is the mobility of the last two lights static?

[lost wyvern]

Yeah, but this is for post processing, isn't it? I wanted for it to show up in the editor without having a PP material

[bright frigate]

what do you mean?

[bright frigate]

They're all the same - stationary

[faint pasture]

Show your logic for how the lights are controlled.

we can't just sit here and guess why it's not working without any info

[bright frigate]

here's one

[bright frigate]

why so agro? I stated it wasn't working, I shared a picture, I said that the array was not showing the final 2 objects in it and then that adding a foreach loop (in the picture above) solved it

[odd ember]

you have to set the custom depth mask inside of the material itself. talk to people over at #graphics for how to solve it

[naive grail]

[lost wyvern]

I'm using a different pawn in there than the player spawned with in the persistent level, is that the problem>?

[heavy lion]

So, I have created this blueprint https://blueprintue.com/render/99zrvi45

breakpoint it and see if there's anything going on

[worn ledge]

does anyone know of a way to get all blueprints that implement a specific interface? GetAllActorswithInterface is only returning actors that exist in the world and I need a way to just get them all

[fiery swallow]

you want references to things that don't exist?

[worn ledge]

no it's an existing blueprint but it isn't present in the world

as in you don't have to drag it into the viewport in order for it to be registered

[odd ember]

you mean UObjects with interfaces?

UObjects aren't exposed to blueprint generally by design

[worn ledge]

UObject?

[dreamy pecan]

Any thoughts on the best way to data model character skins? Current version I'm thinking is just skeletal mesh + material instance array (I want to share skeleton and animBP across skins)

[twilit heath]

for multiple nav agents, even that doesn't help

[faint pasture]

Uh, any reason I wouldn't be able to update to 4.27.1?

[odd ember]

UObject is the base class for all classes in the engine. Actor is the subclass that can be placed in world. most BP logic only extends as far as actors

[worn ledge]

ah, alright then I'll just have to do something else

[twilit heath]

you can make UObject derived blueprints

they aren't even very limited

[odd ember]

but you can't use Get All Objects of Class the way you can Get All Actors of Class

[twilit heath]

no, but you can have them register with some easily accessible class

[odd ember]

true

a pseudo subsystem

@worn ledge what is it that you are trying to do

[worn ledge]

I wanted them to be automatically accessible without having to manually register anything

like there's a series of objects that I need in a list

[odd ember]

this is as elegant a way as they come

[twilit heath]

there is also a silver lining to registering

its much faster then get all actors

[worn ledge]

well get all actors only happened the one time at startup so it wasn't a huge deal

[odd ember]

I think the issue is that Objects may be initialized before BeginPlay

[twilit heath]

that depends on what constructs them, and when

[worn ledge]

they're static the objects just hold some data and functions

[twilit heath]

we have literally everything initialized and ready to go before BeginPlay gets called on anything

[worn ledge]

anyway, thanks everyone

[twilit heath]

does the data ever change at runtime?

@worn ledge

[worn ledge]

no

[twilit heath]

then make a data asset

[odd ember]

yes but if you were to pull the registering in something like GameMode you couldn't be certain it exists before you start the registration

[worn ledge]

data asset?

[twilit heath]

it can hold data, it can hold functions, and it can be referenced by anything via direct asset reference

[worn ledge]

well that would work but is there a way to address a group of them en mass at run time?

[twilit heath]

you make an array of data asset references and just assign them on the CDO

as a simplest variation

[worn ledge]

yeah, honestly I think I'll just go with registering objects as normal, I'm trying to go for something friendly to noobs more than anything else

[twilit heath]

data asset exist to do exactly what you need here

[worn ledge]

hold on I need to just google it, thanks a ton for the help

So I am using a sphere collision around my character to check for items that I can pick up, I currently have my items set to overlap all, but I want them to have physics and react to gravity and my player if I walk inti them, but turning on physics just drops them out of the world

What custom collision would I need to use to achieve this

[obtuse herald]

Inputs can be consumed by input events (i.e if you have 2 'K' key events, one of these will consume the event and let the other not fire). Also if you use Input events outside from your controller space you need to set Auto input in the Actors details panel.

[white field]

ah, hmm, interesting..

[obtuse herald]

You can turn the consuming off in the events detail panel

[white field]

ok I will look, tyvm!

pull from it SetStaticMesh

[eager nest]

thanks! was a bit of a noob question

also, is there a way to do this with less nodes:

hey guys I am trying to make a function, that checks if widget is a part of other widget's hierarchy, but I'm kinda stuck. I guess the best way would be to have an array of integers to navigate through each GetAllChildren, like in the picture attached. does anyone know how to create such function?

I don't remember but can you just get the widget's parent widget?

If so, you could just traverse the parents until you either run out of parents, or the parent matches the desired one

I'm making a game where the game asks all players a question, first person answer proceeds to next round.

Where is the best place to "manage" the question from, level blueprint?

Like I'm not sure where I should make this blueprint

[spark steppe]

make an actor which is the game manager

[maiden wadi]

Level blueprint 🙁

[sick sapphire]

In the default third person character playerblueprint,
how do i disable whatever makes the character turn towards the direction of movement

thanks

[unborn turret]

is there any way to add hyphens between a string after every 4 characters?

[maiden wadi]

Don't even really need to do that if you get the character array. Loop over it, and every fourth loop, add a hyphen at the index and increment.. Oh wait.. can you ++ a blueprint macro's loop iterator?

[unborn turret]

hmm

its appending all the hyphens in the beggining is my branch statement wrong? @maiden wadi @trim matrix

[last abyss]

0 mod 4 is 0, and arrays start at index 0 so yes it is wrong

[unborn turret]

ah right

got it

thanks

Hi, I'm trying to make a crosshair (static), is it better to use HUD BP class or Widget?

[spark steppe]

doesn't really matter

i would use HUD, tho

[sage pecan]

I tried using HUD class, but it seem to not appear on screen even after I set gamemode's HUD class to my HUD

Do I need to call it in my player BP like using Widget?

[spark steppe]

iirc gamemode should be sufficient

but not sure actually

[maiden wadi]

To change the HUD class, just set it in GameMode, and make sure that map is using that game mode in project or map settings.

Simple crosshairs are fine in HUD, but if you need more complex stuff like interaction displays around the crosshair and such, it can be much easier to drop into a widget.

[sage pecan]

So is it better to learn using widget for the long run? (If will be using dynamic, hit marker)

[shut escarp]

hello how do u communicate between two different gamemodes and player controllers between two different levels?

[tame pecan]

Game instance is one way

[gentle urchin]

Or savegame

[scenic kindle]

Depends on the game though.

[shut escarp]

im trying to make a team selection in the lobby then open another level and have the player join their selected team

im using a lobby gamemode and controller then switches to game controller and gamemode when game starts

[scenic kindle]

You would use a game instance for that.

Or just change the default gamemode for that level.

Same with the player controller

U would use a game instance only if the different teams had different gamemodes. But if all of the players have the same gamemode regardless of teams, it’s unnecessary

[gentle urchin]

Is it even possible to have different gamemodes based on teams? Didnt think so

[scenic kindle]

I dont think so. You can have different player controllers i think.

[faint pasture]

Why would you do that, or what exactly would that accomplish?

[gentle urchin]

I dont, i just read the above comment, and it sounded like it was a possibility

[trim matrix]

How can I spawn the player BP after a sequencer gets done playing?

[scenic kindle]

Save which team the player is on to a game instance and when you open the game level, set the variable in the character to the variable in the game instance.

[scenic kindle]

There’s no connection to the execute pin.

[mild flare]

Hello!
This is the sound played by a shotgun, since it is firing 6 pellets at once it plays the shooting sound of the shotgun 6 times. is there any way to prevent this? I am having this logic inside of a function

google didnt help so far

[maiden wadi]

@sage pecan I would personally go with Widgets. If you're aware of how they space themselves on screen, it's very easy to put one in direct center of the screen by simply adding it to viewport and setting the correct values.

For instance, these functions called on a crosshair widget.

[gritty elm]

use "do once" node and then reset it back after 6th trigger

[mild flare]

@gritty elm its still happening

[gritty elm]

did you verified your sound? maybe your sound itself is triggers many times

the code you've shown in image is inside actor. If you spawn this actor 6 times, then it will play sound six times?

[paper galleon]

Depending on the method of firing, it seems you're playing the sound 6 times. Show more of your code prior to playing the sound

[mild flare]

@gritty elm thats the sound cue, it is inside an actor as a function (if that makes sense)

[gritty elm]

did you tried to play only sound cue in the editor ( just to make sure it only plays once )

so if it doesn't, then you probably spawning sound attached multiple times. Add breakpoints or print string ( just to make sure it only print string once

[paper galleon]

I bet you're using a for loop to spawn the actor right?

It's going to play six times that way. You can play the sound OnCompleted if so

Show code and get help.

[gentle urchin]

If its inside a function, does do once even work?

[gritty elm]

don't use do once inside function. you need to have strong concepts about functions

[gentle urchin]

I would think not

[mild flare]

i try outside the function

[gritty elm]

Yes, spawn the sound stuff outside of function

[mild flare]

lol that fixed it

[paper galleon]

Show where this function is called

Let me check something.

[mild flare]

thanks alot @gritty elm @paper galleon @gentle urchin ❤️

[gritty elm]

sure.

[gentle urchin]

Probably need to reset the do once on reload

[paper galleon]

Do once shouldn't even be there anymore.

[fallen blaze]

im not sure what it wants me to connect

[paper galleon]

The cast node is not connected

It's pretty obvious

[mild flare]

the do once is deleted from inside the function and i put it in the BP right before I call the function - again thanks alot

[fallen blaze]

yeah thanks i was in my own head about other stuff lol

[scenic kindle]

You can convert it to a pure cast instead of connecting it.

[paper galleon]

😅 you can convert the node to a pure cast of you're sure it's a player controller which it usually is for widgets. That way you don't need to connect it

[paper galleon]

Lol beat me to it

[scenic kindle]

Lol

[gentle urchin]

Right , so the sound works for the second shot aswell?

[mild flare]

yea with a delay i reset the 'do once' node

[gentle urchin]

Alright. If you spawn the actors with a loop you can attain the same effect by plaving the sound node at the "complete" end of the loop. Removes the need for the do once and reset. As Ozy mentioned

[mild flare]

ohhh right

thats probably less counting for the engine right?

[gentle urchin]

And less work for you :p

[mild flare]

@gentle urchin sorry but what loop do i use for that?

[paper galleon]

For loop. First index 0 last index 5

[mild flare]

will try that

[paper galleon]

Spawn actor for each index. Then drag off the on completed pin and play your sound

[mild flare]

it's playing it 6 times again, sorry for the questions here, first time doing the loop thing

[paper galleon]

Drag off the loop body and spawn actor there. Then drag off completed and play sound there.

You might need to create a fresh function for that rather than trying to refactor an old one. Seeing as you're a bit green

[mild flare]

by actor you mean the pellets, right? the sound is just attached to it, do i get that right?

[paper galleon]

As far as I can see , you're playing the sound at the shotgun location.

[paper galleon]

Yeah, the pellets.

I'm not with my pc. I'd have sent an example. Maybe someone else can help

[mild flare]

its fine, thanks alot! will try to get it right and not break the other weapons in the process

[paper galleon]

Yeah. It's quite simple in principle. Spawn the pellet six times and after the six have been spawned, play the sound. That way, the sound plays only once and it's a clean method of creating a shotgun

LoopBody->SpawnActorFromClass(pellet)
Completed->SpawnSoundAttached

First index 0, last index 5

[mild flare]

thanks alot i will keep trying

[paper galleon]

Not sure what you're using hit result for

[true ingot]

hey guys, im really new with this stuff and im trying to learn
basically im making this door here toggalable, pressing E makes it dissapear, then pressing E makes it re appear when you are in its range
but for some reason after making it dissapear the first time it never reappears after pressing E again
any ideas?

[paper galleon]

why are you disabling input

[true ingot]

its to stop you from being able to trigger it outside the box trigger

[paper galleon]

use a bool for that and check the bool is true when you press E

[true ingot]

whats a bool?

[paper galleon]

boolean the Red variable type

You need a few youtube tutorials. Sorry to say

[true ingot]

yeah thats what i was doing, ive been going through some

i did the unreal blueprints tutorial but after finishing it, tho i know how to turn lights on and off there are some areas im not good at

[paper galleon]

Okay, one of the firat things taught should have been variable types

[true ingot]

firat?

[paper galleon]

I'll send something. Give me a minute

[true ingot]

thanks!

[paper galleon]

first. typo

[true ingot]

fixed it

[paper galleon]

this won't work as intended

[sturdy herald]

hello. How can i make a structure array for string arrays?

[true ingot]

i was a fool and was following what i did for the lights

[true ingot]

seems to be working exactly how i wanted it to tho

[paper galleon]

Try it when not in range. You'll find that it works as well

[paper galleon]

Structure array?

[true ingot]

yeah tho the issue ive had in the past is that the collissions are still there even after the door dissapears

[sturdy herald]

yeah

[true ingot]

ngl this makes less sense to me now lol

what does the "set" stuff do?

[paper galleon]

Sorry forgot something

[sturdy herald]

set the value of variable. The box checked mean the Bool var will be true, unchecked is false.

[true ingot]

bool?

[sturdy herald]

A Boolean variable. It can be true or false.

[paper galleon]

You need a few more lessons. Basically what is happening is that when in range set the boolean to true and when not in range, set it to false. At any time you press E it checks that IsInRange is true. If it is, it toggles the door

[paper galleon]

This is probably the simplest variable type. Either true or false

[true ingot]

Where would you recommend lessons?

[sturdy herald]

First of all, u need to get some basic programming knowledge, to understand things. There are lot of videos for begineers.
But on ue page u can learn too.
https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/Blueprints/UserGuide/Variables/

[paper galleon]

What he said

[true ingot]

i tried learning code, c++ and c sharp n such, but it ended up being too much for me to handle
but then my friend told me to do blueprints which is a visual version of coding and is way easier

[paper galleon]

There is the misconception that using blueprints does not require any programming knowledge. That is far from the truth

[sturdy herald]

U dont need to make codes in UE4, thats true, but the logic behind BP is programming too.

[paper galleon]

It just means that is is faster and easier to visualize your logic

[sturdy herald]

Visual scripting is much easier if u already know any programming language. But the good thing in ue, u can start the VS without any previous programming experience, just its important to think about VS like another languege, just with nodes not with words.

[true ingot]

I mean so far ive gotten the hang of it pretty quickly, sure my methods are a bit larger and less clean but i feel like it still does the job
id just want to shrink it down and make it work

[sturdy herald]

U cant skip learning the basic of variables, functions, macros, etc.

[paper galleon]

You need first to understand what variables and data types are. That is the fundamental of any programming

[sturdy herald]

This things is used in visual scripting too, so u need to understand it.

[true ingot]

yeah and im not planning to
i just didnt know this was something i had to do, all the tutorial videos just threw you straight into it

its also painful that the videos are like 5 hours long

with no editing

it would be so much easier to consume if they were to just cut out the part where they take breaks, or cough, or make mistakes

yeah, im intent on learning this, i just get stuck on some parts

[true ingot]

thx for this link

but is there any youtube videos people would suggest?

[paper galleon]

It's fine. Just don't try to start making the next MMO😂

[true ingot]

im currently going through this but so far it is yet to cover the stuff you guys mentioned

[true ingot]

hahah well i do have game ideas but its nothing stupid complex or anything that weve already seen

[paper galleon]

The thing is that most UE4 tutorials start by teaching about the engine not really programming. YOU, need some level of programming knowledge. I don't know any UE4 tutorials that teach that. There probably are some. But a general programming knowledge is good too. Take one or two days to learn something easy like python basics.

[true ingot]

ah thats a bummer

last time i tried messing around with code i took like a month break lol it was too much for me to understand

[sturdy herald]

Ryan Laley making pretty detailed ue videos

[paper galleon]

Its not. You shouldn't be put off by that. You made the mistake of starting with C++. That is almost always a disaster for someone with zero programming knowledge

[sturdy herald]

The Unreal Engine's YT channel make pretty good tutorials too. Need to know, some thing in videos can be outdated, mb the nodes renamed, but with google u can find this changes.

oh ok ill have a look at that

thx

[hushed pewter]

Anyone have any clue why my blue image has suddenly turned yellow

[paper galleon]

I'm guessing there's some widget with that colour overlaying that image

[hushed pewter]

I made a sprite

[gentle urchin]

It seem to be an image set to button

[hushed pewter]

and it has the same issue

[pale blade]

What's the best way to get a float variable (such as "impact time") given an animation montage inside a normal blueprint?

Animation Montages where you manually set the impact time of the attack:
AM_Attack1: Impact time at 1.0s
AM_Attack2: Impact time at 1.5s
AM_Attack3: Impact time at 2.0s

Then in any blueprint, you can get the impact time given an animation montage.

One solution I'm currently doing (that is very messy) is storing it in Game State: a dictionary/hashmap of Animation Montage - impact time (float) key-value pairs.
So in any blueprint I just grab the Game State and input the Animation Montage to get the impact time.
Of course, it is messy. You have to update the dictionary/hashmap in Game State.

Optimally, it would be nice if I can set a variable for impact time inside the Animation Montage itself. Then in any blueprint I'll just call some function like GetImpactTime(Animation Montage). Is this possible?

[worthy tendon]

have you tried anim notifies?

[gentle urchin]

Or anim states

Allowing to be at desired length, has a begin end, and tick notify avaliable

Used by the ActionRPG template

If you wanna see a sample of it

[next kite]

Hey guys, I've a bit of a UMG issue. Basically i've been plugging the progress bars into my throttle and brake output

and steering also

but when the games deployed, it does not show. It shows up inside PIE mode however

is there a reason for this?

[tepid pike]

Does anyone know how to make player movement speed separate from framerate? (using blueprints)

[gentle urchin]

Adjust by delta time

Doesnt the cmc handle this already

[white field]

argghh, I cannot unload this streaming level for the life of me. I do it in other sublevels fine. what can be going wrong? if I trigger to load a new sublevel and unload the map in question immediately upon Begin play, or at the end of my initial begin play routines, and it loads and unloads fine. but in this particular map, if I try to call it by custom event, bound event, even debugging input, it refuses to even print a string from the routine

it's the exact same approach I use in the other sub levels. is there a way to force the file to rebuild or something? it compiles fine but failing to print a string is messed up

[bold shard]

Is there a way to see the blueprint call stack in UE5? I cant find the option

[odd ember]

blueprint debugger window. only visible during breakpoints

[bold shard]

Am I doing something wrong then? I stick a BP in my function, which is three funcs deep (UpdateObjective> UpdateQuestLine>UpdateQuest), and this is all I see

If I want it to update, I have to step over/into things, and it only keeps tracks of the nodes I step onto

[odd ember]

from what I can tell it does what it says on the tin. I think those objects being deleted may be part of your issue

[bold shard]

As far as I can tell, they aren't deleted. I am in a single object, and if I step out the Exectuion Trace will update, showing the new node at the top. It isn't a call stack, it just keeps track of what nodes I stop at, in the order I stop at them

[odd ember]

there should be a stack trace tab as well

there are 3 tabs usually

[bold shard]

I'm creating a game with planes as pawns.
So I know that a controller can control a pawn, so in this situation the pawn will be the plane.

What should I put in the controller and in the pawn? Do I put the health in the controller or the pawn and where do I put the controls aka movement WSAD etc ?

Hope everyone has an amazing weekend 😄 (or will have)

[odd ember]

this is what the 3Cs are based on

camera, character, controller

[steady wyvern]

hi someone can help me

[devout dove]

So the health goes into the pawn, because if it dies the health doesn't need to be persistent, stats and equipment should be in controller same as movement?

[odd ember]

input should be in controller

[steady wyvern]

with blue pront

[odd ember]

anything that is related to the character, should be on the character

[steady wyvern]

iaa

[odd ember]

if the player dies, what object really dies?

[steady wyvern]

i

[odd ember]

this needs to be stickied or a bot command really

@devout dove if you have further questions feel free to ask

[devout dove]

So the idea is to let the Pawn/plane die and then be respawned with full HP etc.

[odd ember]

I meant that as a way for you to think about what each object is responsible for

another way of thinking about is that: controller is the player (and has all responsibility for player action), pawn is character (and has all responsibility for character action), view is camera (and has all responsibility for view presentation)

[steady wyvern]

help meeeeeeeeeeeeeeeee

[worthy tendon]

try to ask your question clearly otherwise nobody can help you.

[steady wyvern]

why when i mix my prject said invalid class

for example for main charchter

when i assign to third person controller a hud and try to assign the same hud say invalid

how i can attach the hud to my new charcchter

its a game with two controllable char^achters

in different scenes

[devout dove]

Thank you

[tepid pike]

Thank you! thought something was wrong but I also did a lot of stupid little changes to my settings but it works perfectly

[steady wyvern]

helppppppppppp

[worthy tendon]

you have to recreate some nodes. or probably you are missing some blueprint classes.

[steady wyvern]

the class is how i named

the charchter

where

the probelm is the main charchter

one is warrior 1

and the other i didnt chnage

[worthy tendon]

go to those error links and show picture of your blueprint.

[steady wyvern]

how i can edit

blueprint

says read only

[formal wren]

How can I set the Camera Transform of my player pawn? This doesn't work:

Camera changes location, but keeps looking in same direction

[odd ember]

is this first person

[formal wren]

Yes

[frank nest]

So I am trying to send a blueprint interface call to from a radial menu widget and I can't seem to cast(and I dont want to really) to my character class fox that is following my human player around... How can I get my BPI to send to the right place

[untold girder]

how do i change the character movement speed for the SideScroller character through code like change it by pressing an input

[frank nest]

but my interface on my fox character inside the interface function doesn't seem to receive anything 😦 Ill check out the select!

[frank nest]

get a reference to character movement and set the max walk speed to something you want

E.g. use shift for a sprint where you will set the max walk speed you currently have to double then when released back down to normal

[odd ember]

I don't know the specifics of the first person character in BP. but you should be able to rotate the camera on its own, even though it's not recommended

[sturdy herald]

I get this problem some months ago. If i remember correctly, i worked on some images in Photoshop, if i saved the photoshop file as a TGA (so not exported it, UE can use TGA files as image), then everything was fine.

[sand wasp]

Sorry but how do I get an event from the owner of the component

[hushed pewter]

Ah

My problem is its a png

Ill try turning it into a jpg

[sturdy herald]

png better then JPG, idk UE how working with it. If u dont have a photoshop downloaded on ur PC, write me a direct message, send me this photo, and i'll send a TGA just to test it.

[sturdy herald]

can u give a more details about ur problem?

[formal wren]

Mmmh, nope. Thats what I try. The camera moves to new transforms location but doesn't change view direction

[sand wasp]

so I wanna access the hit event from an actor from an actor component

[odd ember]

try changing it in the player camera manager instead

perhaps that will work. but maybe it's hard coded not to

because again, it's not recommended

[sturdy herald]

Still not clear for me, maybe because its pretty late. Can u show image from ur blueprint?

[sand wasp]

there are no images as it's not working. I'm trying to somehow get the Hit event from the BP owner to the attached Component

[sand wasp]

and it's kinda not working cus there is no such event

[formal wren]

If I untick 'Use Pawn Control Rotation' I can set the rotation manually. But then it wont follow my pawn anymore

This one works:

I think ^^ Have to investigate further

[sturdy herald]

So u want to make some changes with an event related to a component if the BP owner is hit?
U can make custom events for that.

[sand wasp]

well, something like this...idk what i'm doing wroing

[formal wren]

Works to change player camera. I use it with 'Find Look At Rotation' to set focus

[frank nest]

@trim matrix so this is the interface call in the other character but the string never pops up and nothing fires

[sturdy herald]

U can use the Event Hit node (https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/AddEvent/Collision/EventHit/ )
Or if u have a specific projectile or something like that, then u can use a collision box (the Third Person and maybe the first person have one on default) and on that collision box with Event Begin Overlap u can "sense" the projectile.

[sand wasp]

oh my bad @sturdy herald ...I wasn't aware of the other node. now it works just fine. I was taling about an component and not the actor btw :D still thanks

[sturdy herald]

good u get the result what u wanted:)

[idle crescent]

In general what's the greatest slope angle NavMeshes will work with>?

[polar stirrup]

If I wanted to handle clicks different for a button inside a UserWidget, such as left click does action A and right click does action B, what would be the best way to go about handling that? I see that a Button has an OnClickEvent, but from what I can tell, that's only for left clicks. Thanks! 😄

[frank nest]

unsure what you exactly mean other then adding a breakpoint in certain areas but on forums I am getting conflicting information that my widget by having a reference to self wont send the interface call without the correct target which then I would need a reference for it like a cast

so what should I plug into target here if what I am trying to cast to is a character

@trim matrix I appreciate the help btw 🙂

[sturdy herald]

In your charachter blueprint, use this nodes (just write in search). In ur widget make the bool variables (RightMouseButtonPressed, LeftMouseButtonPressed).
Make variable in charachter blueprint, in type list search for the name of ur widget and make that the type of the variable. From the Charachter blueprint with pressed/realesed change the value of the bool var in widget. In Widget Graph, at OnClickedEvent make a Branch and use this bools as u want (note that both of the bool can be true at same time, but depending how u make the conditions, u have a chance to make a right click or left click dominant button, with sequence both of the actions will be called, etc). I have a sample from one of my project's first person charachter, just im using the D and G keys for calling some events in widget BP.

[steady wyvern]

I FIXED NOW HOW I MERGE

thrid charchter controller qith start location

[odd ember]

is that your character blueprint being responsible for a widget?

[sturdy herald]

the widget is created for the charachter user and added to viewport.
Btw, @polar stirrup, u can promote to variable the Create Widget's "Return Value" output when u're created the widget.

[odd ember]

why would you make the character responsible for the widget in this case? seems like the logic is tripping over itself

[sturdy herald]

I dont know what u mean when u say the character is responsible for the widget or what is the problem with it

[onyx frigate]

Hello guys and gals ! Do you know how to use a timeline outside of an actor ? I am creating an action system (action derived from uobject) and can't use a TL in the BP ...

[sturdy herald]

u can make i think any time an actor just for this purpose (if u cant place this TL in another actor) and cast to it when need.

[onyx frigate]

But I will never be able to use it like a regular TL on my "action" ...

[odd ember]

use a timer

and a curve, if necessary

[onyx frigate]

I can use a curve directly like that ? I noticed I could add a TL variable on my object also ... And set the curve if I needed but it doesn't appear as a regular TL anyway

Easy to use a curve directly in a BP ?

[odd ember]

well it's not hard

just use GetFloatValue

and boom

[onyx frigate]

Perfect

[white field]

finally found it! a spot where I was killing off the previous player pawn before spawning a different character type had an error where I was destroying the level instead of the intended child actor.. thanks again for helping me.

[odd ember]

ah yes, the classic destroying the world instead of killing children mistake... we've all been there

[white field]

lol, thanks ;D

you'd think that destroying the level itself would annoy the engine at least a little

the whole thing was supposed to be a shortcut time saver too, haha

[sand bloom]

hmm am I blind? I have a gate that refuses to close, my variable is 0 as told by a print string. And yet, it does not close. The event is done trough a tick

this seems like such a simple thing that should work

The open and close branch is done by a constant raycast

both are firing

[static charm]

just disconnect ur boolean and make it false always

to test it

if that works, then you know something is wrong with ur Go Up variable not being set correctly, or if it doesn't work then you misunderstand whatever is happening after it exits the gate vs what you thought it should do.

[sand bloom]

hmm I did this and it still fired wtf lol

I thought a locked gate would block any input

[static charm]

it does, unless you edited the Gate macro code

[sand bloom]

I did not

so I am very confused

[static charm]

sometimes we work on stuff too long and forget whats going on. I would disconnect the Exit too.

that what you know some other code isn't running in place of

[sand bloom]

oh I did, when I do that it doesn't run

[fast escarp]

Wondering if somebody could clarify, is CameraShakeBase in UE5 the same as CameraShake in UE4?

[static charm]

well there's also order of operations/execution, so it's possible the gate can run once or a few times before it gets closed.

[sand bloom]

yeah that's understandable, although mine just keeps running

0 is my variable

and hello my event firing

lol

[static charm]

then something isn't called the branch

[sand bloom]

hmm

[static charm]

use the "Check Whether..." event, split it with a Sequence

[sand bloom]

damn

you're right

I think

[static charm]

then from the Sequence you can connect right to your branch

and do both things with just that one event

[sand bloom]

Yeah it works now, only half of it was calling it basically

thanks ahah

[static charm]

nice

[static charm]

no idea, but replying so your question is bumped as new

[sand bloom]

#ue5-general may be useful aswell

[gray chasm]

so... when I hide an actor and then show it again later, it's fallen off through the bottom of the world because I turned collisions off on it; rather than just setting hidden and collisions to off, is there a generic 'suspend' actor function I should be using?

[static charm]

why did it fall?

[gray chasm]

it has physics

I guess?

[static charm]

so turn physics off for the actor too

[gray chasm]

It seems odd that I have to guess what the 5 or 6 things I need to toggle on an actor are

That's why I'm asking if there's a higher level function I should be using instead.

collisions, physics, visiblity, tick

[worthy frost]

not really

[gray chasm]

... on the parent and all child subcomponents?

[worthy frost]

you need to disable physics, collisions, etc

[gray chasm]

mhm.

Oh well, library time.

I'm surprised, seems like a common use case to me.

[static charm]

well you're basically just deleting the actor lol

without deleting it

[gray chasm]

you're retaining the state; you could snapshot the entire object state into a struct

destroy it

create it later

but serializing the physics state is a pain

I'll just writing a library function for it~

[worthy frost]

i just made a wrapper function to handle it

[compact ledge]

does anyone know why could this cast fail? i used it from another project (that i use as a guide) where it works fine but on mine it fails even tho it have the same stuff!

[fast escarp]

Can I make a select for bool? Looking to do this but with true/false

would like to avoid infinity enum equals

am dumb, immediately answered my own question, switch pin type to bool

Is your HUD class set to BP_HUD in your Game Mode settings?

[compact ledge]

thanks!!

Does anyone know where this node is? I can't find it at all

[earnest tangle]

It's for animation blueprints I think

so if you're trying to use it in something that's not an anim bp it probably won't show up

[pale blade]

Hm, I tried typing it in Anim BP but I still can't find it even with context off
