am I missing a node?

[void comet]

Wonder if anyone can help me. This is my shooting BP. Takes position and rotation of an arrow I have set up to follow mouse, to set up the spawn direction and rotation and I set the velocity in that direction multiplied by my charge meter. Problem is that spawned projectiles spawn further away from my character the longer I charge. Any one can work out why? and how I can fix it?

[vocal elm]

can you really not search the world outliner during a breakpoint?

[void comet]

@fast lintel You tried a FLip=Flop node?

Flip-Flop*

[fast lintel]

oh yes i could remember that

thanks

[void comet]

nps

Anyone able to help me?

[vocal elm]

in your offset, I think it looks like its adding the forward vector into the offset, the more you charge, the more it will add to the start position since the position include the forward vector

big word is i think though

[void comet]

Figured it was to do with offset. How best you think to fix it?

[vocal elm]

separate the forward vector from the charging so it doesn't add to it

[subtle falcon]

Hi, i am facing the weirdest problem ever had…

[void comet]

Not sure where that is happening. The charge is just a float made by a timeline

Ah no I see. But what can I use instead of forward vector to calculate the offset?

Will using right vector and rotating it work?

Using right vector seems to just do same

Anyone got an idea what to try next?

I can see the problem but not sure how else to calculate the position without the forward vector

Now I have gone back to thinking that cant be the problem. I am increasing velocity by the charge after its been spawned. How can that change the spawn point?

[vocal elm]

your multiplying your forward vector by 120, thats then getting applied to the spawn transform, try adding it instead of multiplying

[void comet]

I already tried that, it doesnt make difference

the forward vector is from the arrow i am using to visualise direction of mouse, which I use to make the transform. None of that is connected in any way to the velocity change that happens after

Weird thing is how increasing the charge increases spawn location in any way...just dont get it

How does increasing velocity of the projectile after its spawned change the spawn location..its just so weird

[atomic salmon]

With a projectile movement component you need to set a spawn location and a direction. The projectile will be spawned at that location and will be given that direction. The velocity of the projectile after it is spawned is set within the projectile movement component itself.

It will be shot along the direction you have set on spawn, unless you uncheck the option to use a local velocity.

In your code you seem to offset the spawn location, which makes the projectile “appear” further and further away depending on the offset. You want to use a “fixed” spawn location instead and change the projectile velocity depending on the charge.

[void comet]

But isnt the offset the same each time?

[woven arrow]

hey, whats the best way to make enemy movement frame independent? I was trying to work off of delta seconds in the event tick, but i have some people trying the game on better pcs than mine and the enemies move way too fast, so i know i screwed up somewhere

[void comet]

The offset is just the forward vector of an arrow multiplied by a float which is 150 each time..why does increasing velocity of my rocket change the offset?

[south merlin]

Is there like a math node that makes whatever it encounters a positive number? I'm getting back a -0.00, and Scale3D does not like the negative

[void comet]

It seems people keep thinking that the arrow is my projectile but its is not...its is just a arrow i have connected to my player that rotates in the direction of my mouse cursor

[south merlin]

(I expect 0, just not negative 0)

[void comet]

@atomic salmon All my offset is doing is increasing my spawn location along the forward vector of my arrow so that it spawns a little distance away from my character...is there another way i can as you say make it "fixed"? Altho I still can't see how setting my velocity after spawning is changing the spawn location

[atomic salmon]

Your code is not very straightforward so be patient while I try to understand it. One thing you have to realize is the following. The components of a direction vector change as the vector rotates. If you want to just scale the vector but maintain its direction you need to multiply all components by the same amount, otherwise you rotate it.

[void comet]

Nps Marco thx for help as usual

[atomic salmon]

I believe your problem originated from all the braking of the vectors and the acting on the single components

[void comet]

Pretty sure I had the problem before I broke them....was trying to fix it

[atomic salmon]

Start by spawning your projectile at the arrow

So you need the arrow world location and world rotation

And just compose them in a transform, then pass it to the spawn node

[void comet]

Isnt that what I have there?

[atomic salmon]

Do it without braking the vectors

You can add the adjustments later with vector math

[void comet]

The thing that is confusing me is the only thing changing when I charge the weapon is the velocity of the projectile AFTER it has spawned. There doesnt seem to be any relation between that and the spawning

[atomic salmon]

Is your projectile simulating physics?

[void comet]

no

[atomic salmon]

Ok so it is kinematic

Try this

Make an spawn velocity vector variable in your projectile

Check expose on spawn

In the construction script for the projectile take its value and assign it to the initial velocity

[void comet]

Yes it doesnt work this line

[atomic salmon]

In your code, pass the desired spawn to the spawn node

[void comet]

pretty sure i tried this b4

but ill try again

problem I had was the calculation for setting the velocity happens after the projectile spawns so cant enter it as a variable

get a null error

[atomic salmon]

Ok. Can you check if the projectile movement component has a Set Velocity node. Can’t recall right now

[void comet]

yes

its what im using to set it

[atomic salmon]

SetVelocityInLocalSpace

Is it exposed to BP?

That’s what you want to use

[void comet]

ive tried it ticked and nonticked

[atomic salmon]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Game/Components/ProjectileMovement/SetVelocityinLocalSpace/

[void comet]

oh thought u meant the boolean.....ive tried replacing set velocity with set velocity in local sapace and didnt seem to make any difference

Yer just tried it now. Still same problem

[atomic salmon]

what do you do with the projectile speed passed to the spawn node?

and did you change any default settings in the projectile movement component?

[void comet]

nothing atm...was my attempt at what you mentioned a bit ago

ive changed a lot, trying diff things

nothing unusual is ticked i dont think

[atomic salmon]

I am pretty sure you can set the initial velocity of the projectile on spawn and make it work that way

Not sure why it doesn't work for you

can you use just the forward vector of the arrow as is, without changing its component, to plug into the part where you set the velocity of the projectile after the spawn

[distant heath]

can someone explain why i might use one of these over the other generally?

[void comet]

Well to get the projectile movement componenet the projectile needs to be spawned

[atomic salmon]

ok let me do a quick test

[void comet]

So cant use it to calculate the new vector on spawn

Gave me null errors when i tried

[atomic salmon]

I am doing a quick test on the FPS template

[void comet]

k man thx

[atomic salmon]

works for me

set set an Initial Speed float var (not a vector as I wrongly state above)

[fast lintel]

hi guys
i cant wrap my head around on how to have a combat system, in which when i have a weapon in hand my attack animation is different than if i have an axe..
i want to throw punches if i have nothing in my hand, but axe slashing attacks if i have it wielded
anyhelp i can get?

[atomic salmon]

@void comet make it instance editable and expose to spawn

your construction script should look like this

[void comet]

Ah yer I told you before I cant set initial speed because velocity takes precedence and I am calculating my own gravity

[dark crow]

iirc Pure one aka first everytime it's called it will generate a new RandomLocation for where it's pinned into
Second one aka Impure will keep the RandomLocation consistent after the call

[void comet]

If you could make it work with Velocity instead of initial speed it might help me

[distant heath]

thank you!

[atomic salmon]

@void cometwhen you use Initial Speed, Velocity is a direction vector in local space

so you don't need to set the Velocity as long as the projectile needs to fly in the direction of the arrow

[void comet]

Initial Speed literally does nothing in my game. No matter what number it is...does nothing. I found out because velocity overrides it

[atomic salmon]

When initial speed is set to something != 0 velocity is treated as a direction vector. That's what the code does.

Maybe you can try yourself within a blank FPS template.

[void comet]

In a blank template yer but literally doesn nothing in mine

I am setting my own gravity for the projectiles here

This seems to break initial speed

Which is why I am forced to do it with velocity

[fast lintel]

guys can i mirror an animation? so that i make an attack thats for a left handed stance be right stance?

[void comet]

If I dont multiplly the Charge by the velocity in my BP the missiles work fine. My offset works perfectly. Spawns the projectiles infront of the arrow......soon as i add the charge bit the offset screws up

[vocal elm]

try in #animation 🙂

I'm having an issue, I have 1 blueprint, a cube with sphere collision. and 1 event I want to fire on overlap in the cubeBP. If I have 2 of the same actor in the world and touch them together, they both attempt to fire the event. How can I check the actor by its instance so I can fire the event on just 1 of them? For example, I want to set my held cube as the current instance. I'm trying to attach 2 actors together. I can attach actor A to actor B,C,D,E,F ect.. but I can't attach actor A to A because they try to fire the same logic on eachother

[fast lintel]

hi guys
i cant wrap my head around on how to have a combat system, in which when i have a weapon in hand my attack animation is different than if i have an axe..
i want to throw punches if i have nothing in my hand, but axe slashing attacks if i have it wielded
anyhelp i can get?

[atomic salmon]

@void comet tried changing the gravity of the projectile on spawn and still works

even random gravity

[void comet]

the initial speed?

[atomic salmon]

both work

[void comet]

hmmm

[atomic salmon]

Hi! I had attempts to calculate the angle between the 2 vector, but all calculate was wrong somehow. Any idea?

[woven arrow]

hello again, i posted this question above, but another conversation was going on, so i'm going to post again and hope someone might be able to help me.

whats the best way to make enemy movement frame independent? I was trying to work off of delta seconds in the event tick, but i have some people trying the game on better pcs than mine and the enemies move way too fast, so i know i screwed up somewhere

[fast lintel]

hi everyone i need help, i'v set the sheath and unsheath to key R, but in the tutorial video he sets it to left click, so when not attacking he unsheaths with click, and if ready to attack he left clicks again and attacks..
thing is
i want letter R to be the equip and unequip, and i want to attack with left click
but i cant find a way to incorporate the left click input to the R input of sheathing and unsheathing sword

[woven arrow]

sorry, this is in addition to the post i made above

How come I can't add rows to my DataTable? I derived it from a struct and there's no reason it shouldn't be editable

this is what it looks like

Nevermind, figured it out. It's a composite table

[runic urchin]

How would I go about switching a Spawn Actor BP with a input action?

[pale blade]

Anyone also experiencing a bug with trying to add DateTime with TimeSpan? The moment I drag the TimeSpan into the bottom input of the Add, it just changes to TimeSpan + TimeSpan

[minor lynx]

if im making a multiplayer survival game is the playerstate class the best place to store health or should that stick to the pawn?

im thinking stays with pawn but things like xp and levels would be stored in playstate since that persists past death

[dawn gazelle]

I think you're misreading what you're seeing. You have a date time plugged into the top pin of the +, and you appear to be hovering over the bottom pin of the + which would show timespan structure.

[dawn gazelle]

Normally I would think hit points are attributed to the pawn itself rather than the playerstate. Eg. Does a player's state need to have hitpoints if they don't have a pawn they are controlling?

[pale blade]

I tried it out in UE4, it works
But it doesn't work in UE5

1. Drag DateTime into the top of Add
2. Drag Timespan into the bottom of Add
3. Confirm that the DateTime automatically disconnects from the Add node
4. Confirm that the Add node automatically turns into TimeSpan + TimeSpan

[maiden meteor]

Hi !
Can someone help me with changing all materials indexes to one (aka make the whole mesh have the same material even tho it's broken into elements?

[maiden wadi]

@maiden meteor Why not just apply the same material to all of the mesh's material indexes?

[burnt nest]

You would need to do that in a modelling program like Blender. It can't be done in UE.

[brazen stirrup]

can u replicate aim offset with control rigs and blueprint?

[trim matrix]

Hey everyone, having issues with creating a first person freelook system. I’ll do my best to explain because my internet is out currently so no video, unless you want phone quality
So I have freelook done, I set my min and max yaw and pitch so you can’t look at stupid angles or see stuff you aren’t supposed to, upon releasing your view is back to full 360 turning, so that works.
My problem is that let’s say you load in team A facing 12, you press the freelook key, you can look 90 degrees left, right, up like I designed
But if you turn to look at 9 then press the key, you can turn zero degrees left, but 180 to the right. If you spawn opposite team B, you spawn it looking at 6, so you automatically snap looking toward 12. I'm not sure why it doesn't go off your own rotation. Also, Wherever you look, once you stop holding the key, you automatically snap to that, I ideally would like to revert back to the original.
does anyone know how to remedy this? Thanks for your time, either tag or PM me so I don't miss a message.

I'm going off a very simple system of Activate and deactivate my regular and freelook camera as no youtube tutorial worked for this particular project (it did on others)

What can it be if a mesh doesn't recognize collisions? I have a lightsaber blade and a droid skeletal mesh. Both have collisions enabled and set to BlockAll. I added a print method to both on component hit events but none fires.

[fiery swallow]

Are you sure it's skeletal mesh or static?

If it's skeletal mesh you should be using a capsule I believe

[light token]

Yes it's a skeletal mesh

I'm going to check the collision settings.

It has capsule collision enabled

@fiery swallow

[fiery swallow]

Did you check generate overlap events?

It's a checkbox

[light token]

yes

I also added an event to print on overlap

doesn't fire

[fiery swallow]

You said you set everything to block

?

[light token]

I tried both blockall and overlap all

presets

[fiery swallow]

Is what you're trying to overlap also generating overlap events as well?

[light token]

yes

I added it on both the droid and the lightsaber blade

Strange thing is when I hit it with the lightsaber hilt it generates overlap events

but the blade isn't

[storm falcon]

hey there, im new to unreal engine,I have actually covered materials chapter,. Im trying to learn more abt blueprints rn, can you guys suggest any online TUT's please/

[fiery swallow]

And its all the same capsule?

[light token]

The blade is a child of the hilt

I don't know if its the same capsule. How can I check that?

[fiery swallow]

If that's the case it's the same capsule

You just need to set the parents capsule to be the size long enough for the blade

[light token]

OK

I think i've got it

sorry to have bothered you

[fiery swallow]

Or override the parent capsule and make a new collision capsule for each individual blade

[light token]

This was in my construction script 😦

[fiery swallow]

...

Hahaha np

[light token]

Thanks for your dedication

[brazen stirrup]

I think ive found a solution

but I cant confirm until i try it

[atomic salmon]

On learn.unrealengine.com you can find some basic and advanced blueprint courses.

[brazen stirrup]

@atomic salmon are you familiar with control rigs?

[candid nest]

hey i am creating action buttons for my androdi game which is multiplayer i am using events so how to make it replicated so that those buttons work propely in all players

like i have to choose run on server or run on client or any other thing

[dreamy basin]

hey i created a countdown of 30 sec in my gamemode i need to make like when the countdown become zero i need to show a animation which i made in sequencer and also stop the countdown but i dont knw how to do i can anyone help me

[maiden wadi]

@candid nestUI is local only. It should be used to call actions in replicated actors that can inform the server of what that client is trying to do.

[candid nest]

hey watch matt aspland vedio it can help u or just add play anim montage when timer = o by branch

[candid nest]

so i should use run on owning clinent

[maiden wadi]

No.

Run on OwningClient is an RPC to call from the server to the client that owns the actor. The input is coming from the client.

[candid nest]

okay thanku man i didnt know that

[gentle urchin]

Is it possible to return the amount of damage taken via the BP node Apply Damage?

[fiery swallow]

event any damage?

is that what you mean

@gentle urchin

[void comet]

@atomic salmon Well it turned out in the end that all I needed to do was when setting the velocity after spawning, I had to just multiply my charge by deltatime. Super easy fix in the end that I would be interested finding out why that fixes it if you mind. When your about anyway. Thx for help

[light token]

Hello. I've got a problem. I made a sliding door using a timeline. And a button to open the door. Now when I press the button the door teleports to world location 0.0.0. The animation is working but the door is teleported to the wrong location. It doesn't stay in place. Can anybody help me? This is my blueprint.

[tight schooner]

@light token is the component it's parented to at the origin (location 0,0,0)?

OR is the static mesh component set to absolute mode instead of relative mode in the Details — Transform rollout?

[light token]

Let me check

[tight schooner]

The static mesh component isn't the root component right?

[light token]

It is

I dont know how to check the transform rollout

Should it be in the right panel of the blueprint?

[tight schooner]

Oh well it can't move relative to another component if it's the root component

[light token]

Ahhh

[tight schooner]

Add a new "scene component" and make that the root, and attached the static mesh component to it

[light token]

Great! Going to try that! Thanks a lot!

[dreamy basin]

@light token https://youtu.be/rjJj_uT85Eo i hope it will help u

[light token]

Thanks! For all the help people. I think I know what to do now.

Will check that tut. It looks a bit like the one I'm currently using.

Hi! Looking for some guidance with my Rolling Template. I've added a simple node group for camera rotation, but I want the forward vector of my ball to follow the rotation of my camera. Would an arrow component help? i've tried a few node groups i've found on forums, but I can't figure it out.

[spice furnace]

hello i need help with this thing am tryin to make

i m tryin to put pickable object inside the drawer

anyone

[gentle urchin]

Yeah, sry had to go to the office... the event any damage yes :) it has a return value but i cant find a way to use it / return it

[fiery swallow]

It works like BPinterface if that helps, or maybe I don't really understand what you mean.

[fast blaze]

hi all what is more correct rotate a capsule component or a mesh only inside? thx

[gentle urchin]

When you do "apply damage" to an actor, that function has a return value with "actual damage inflicted". Im wondering how I can return that value (if i can at all, or whatever magic happens to calculate this)

[atomic salmon]

@fast blazethe Character Movement Component assumes to be working with an upright capsule, so rotating the capsule may cause some side effects. Rotating the skeletal mesh inside of it is harmless.

Hey everyone, I was recently asked how to create and use Blueprint components in a project so I put together a tutorial showing three different ways. Re-usable code is good code.
Hope it helps some people out.

[iron heron]

how would i go about setting or changing the mesh of a skeletal mesh component from blueprint code

i want to change it based on some events

[winged thicket]

ERROR: System.Exception: Couldn't update resource

Hello, I am facing a major problem, which seems very simple and completely illogical at the same time, it has been preventing me from working for 5 days, and my game having already been published is a real disaster for me. 5 Steam keys to my video game for whoever helps me find the solution. Basically, the mouse doesn't influence the movement of the camera, except, I put it in the upper left corner of the screen, and drag the cursor along the screen. After that it goes back to functioning normally, then deactivates again when the same movement is made. Here is a video that shows the phenomenon with the cursor visible.

[desert rover]

I have a problem. I have duplicated the original side scroller character so I can have two players one controls with keyboard and mouse and the other one with a xbox controller, In the level bp I have a create player node and in the level I have 2 player starts. How can I assign the different characters to their own player start?

[earnest tangle]

@desert rover there's a function in game mode which you can override that controls where the pawns are placed. Not 100% sure, but that might be what you need to do here to customize the behavior

[desert rover]

whats the function called?

[earnest tangle]

Choose Player Start or something like that

[desert rover]

okay so should i go an try learn this then

[earnest tangle]

It's worth a try :)

[desert rover]

okay thanks

[fast blaze]

Marco thank you. the question is grow from mechanics like shooting character from the ramps, so the capsule should be vertical, but mesh could follow the curvature of the surface? solution 1 is better?

black - is char mesh

[indigo bough]

I know this is not strictly blueprints, but not sure where else to post about water.

Created a custom Gerstner Wave Generator class, which I'm selecting in my water body actor in the level.

However when I hit play/simulate, it reverts to the default generator option. Anyone come across this before, or knows what might be happening? I tried to set the generator at begin play, but that option is not exposed in blueprints.

[deep warren]

I have a HierarchicalInstancedStaticMesh component attached to my actor, when I set the actor location the hism location(and instances) won't update but if I move it in the editor with the arrows it does, I forgot to set something?

[atomic salmon]

@fast blazeyes, the capsule can stay vertical and the mesh rotated, just mind the fact that the launch direction will be based on the capsule

[fast blaze]

understood thank you

and another one. is it possible to have a collision at the same time on the character and on the attached bp component to it, in my case skateboard underneath, it seems unreal is not working well especially when physics on when phys assets are intersecting...

[chilly jetty]

Hi there

I might be having a brain fart

Keypad is a child actor component on this safe actor I have

I'm trying to get the cleared default bool but either forgot how or don't know how

[atomic salmon]

@fast blazeif you are moving an actor kinematically with sweep enabled, only the root component is checked for collisions

so if you want your skateboard to also be checked for collisions, you need to make it an independent actor "following" the main one

you can also make it a physics actor and attach it to the character with a physics constraint

there is no perfect solution, it all depends on your gaming logic

[iron heron]

why, and how do i change that ?

[willow breach]

how do i play an animation and then when the anim is done it returnes to the animbp's animations

[willow breach]

did u accidentaly set "show mouse cursor" to true in one of your blueprints?

[void needle]

does anyone know why my game gets lighter over time?

[willow breach]

if yes and dont know which, just put in the event tick in ur level, put "set show mouse cursor" to false, hope that fixes your problem :D

[maiden wadi]

@willow breachGenerally you don't. Normally you'll use an Montage for this sort of thing.

@willow breachI strongly recommend reading through these two docs. They're directly related to what you're asking for.
https://docs.unrealengine.com/4.26/en-US/AnimatingObjects/SkeletalMeshAnimation/AnimMontage/UserGuide/
https://docs.unrealengine.com/4.26/en-US/AnimatingObjects/SkeletalMeshAnimation/AnimHowTo/AdditiveAnimations/

[iron heron]

there is an Auto Exposure shader feature in the Project settings, or because you're using raytracing and that's just the nature of it

if u do the latter you should read yourself a bit deeper into the technology to understand it

[willow breach]

i tried but it wont let me put the mesh in target

[maiden wadi]

That is because a Skeletal Mesh Component is not a Character type.

[willow breach]

then what do i do

@maiden wadi

[maiden wadi]

Judging by your other nodes there, you're in a character class already and Mesh is the default skeletal mesh inherited from Character. So either just call Play Anim Montage with a Self target. Or call GetAnimInstance on the Mesh, and then call PlayMontage on that.

The Play Anim Montage does the same thing, just specifically with the character's Mesh component.

[willow breach]

nop

doesnt work

btw im in the third person character blueprint @maiden wadi

[maiden wadi]

Then it's likely that your montages and/or animgraph isn't set up correctly.

[subtle falcon]

No, i set it to true to see his behavior but i fixed my problem since

[wintry karma]

this is probably not that complicated but im fairly new to this and I need help. Trying to make it so when an NPC is talking, the flipbook changes but Im having a bit of trouble (especially with what to put as the object)

[willow breach]

wdym

[willow breach]

the object is the character itself, so try "get actor of class" and choose bp_racoondog, then on the return value plug that into the object

[maiden wadi]

To correctly play Montages, you blend them into your other animations using layers. The two links I posted have all of the information regarding how to do them correctly.

[candid nest]

hey do anybody know how to remove nav mesh from paricular area

[wintry karma]

it worked! thank you very much

[candid nest]

hey i created a nav mesh and a coin system my nev mesh get remove from the place where i add coin can anybody help

[snow harness]

When you use the AttachActorToComponent. Does that attached actor become a child of that attached to actor? Like can I use the GetOwner node in for an attached actor?

[velvet mist]

You'd want to use GetAttachParentActor. GetOwner is for network ownership.

[snow harness]

Ah okay. Thank you very much. That explains why that hadn't worked.

[candid nest]

hey plz help here too

[snow harness]

Ensure everything in your coin actor has collision only set to Query. The coin collision is likely being detected as an obstacle.

[candid nest]

okay

[snow harness]

@candid nest

[candid nest]

ya got it thanks man and can u tell me how to disable nav mesh at certain point

[snow harness]

You can add a Navigation Modifier to the level, change it's bounds, and set it to Null to remove navigation mesh in that spot

[candid nest]

okay thnks again man

What do you mean by "navigate through BPs"?

[hybrid ether]

What is problem? I'm trying to create crafting system. this finds items to craft weapon and it works. But "find" node doesn't find anything but 0. Even if I have key:6 and key:9 in my inventory.

[stuck plaza]

sorry for posting it here, I couldn't find apropriate channel for this. Is there any paper on how to integrate stuff from marketplace to your own project? I wanted to get SuperGrid to work (https://www.unrealengine.com/marketplace/en-US/product/supergrid-starter-pack) but i feel a little lost on how to install it.

[verbal mural]

Hey question
I started a blank UE4 project so i can get better acquainted with the engine. I'm now wondering how would i add in a first person controller. Thanks in advance.

I'd use the FPS template but I also don't know how to change things for it

[dawn gazelle]

For copying BPs, materials, meshes, use the Migrate option within the content browser. As far as integrating marketplace content into your project, that's up to you and your needs.

[candid nest]

it is free just use it and in file explore just copy paste the content to your game contont browser or u can migrate which suits u better

hey does anybody know that how i can travel from 1 place to another in same level when i overlap some actor or like that thing

[dire sonnet]

with a touchpad you can only zoom in and zoom out, there is no middle button so you cant really move the grid

[earnest tangle]

Do a right click and drag

[dire sonnet]

ohh, aight

[earnest tangle]

Middle click actually does nothing in the BP editor :P

[mild shell]

Why when I Draw Trianlgles on Canvas it has no color? Draw line works fine

[lofty thicket]

I'm trying to place a bunch of cube-like objects at specific areas in the world while keeping a relative distance to an existing (original) cube. The cubes all have the same width and length (800) and I'm placing them at a distance of n*800, so if there were cubes placed between the origin cube and the new ones, they would all fit snugly. This works fine when the original cube is rotated (yaw) 0, 90, 180, or 270 degrees, but if it is rotated any other amount then the alignment all goes wrong.

Is there any way of rotating the new cube to match the rotation of the original cube while keeping the correct alignment and spacing and staying as close to the new cube's location as possible? I've tried using functions like RotateVector and RotateVectorAroundAxis, and those work for very short distances, but at large distances they aren't precise enough and they move the new cube extremely far from where I had placed it.

I understand this may be more of a math question, and if anyone has a suggestion of a better place to ask, I'd appreciate it. Thanks

i need help how to drop weapon

[gritty elm]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Utilities/Transformation/DetachFromComponent/

and then set simulate physics of sword to true, so it will fall on the floor

[halcyon laurel]

this is my functions for zooming in ,it work perfect but there is an error after i exit the game i wanna know how to solve it

this is the error

[rancid steppe]

awwww thank you so much

[halcyon laurel]

and this is the node

[gritty elm]

use "Is valid" function after true branch of line trace, the object will be your fps character

https://www.youtube.com/watch?v=dY5XSFpqkos&ab_channel=DevSquad @halcyon laurel

[halcyon laurel]

like this?

@gritty elm

[gritty elm]

yes

input object will be your fps character object

or any object you want

see which object shows error in output log?

[halcyon laurel]

select widget

[gritty elm]

click on select widget function

[halcyon laurel]

then chose first person character

[gritty elm]

Yes

let me know if your issue solved

[halcyon laurel]

its the same unluckly

[gritty elm]

wait

what you are trying to do here?

your screenshot is blurry

[gritty elm]

remove "get owning player pawn"

and use "get player character" instead and let me know if it works

well, you are still doing it wrong

[halcyon laurel]

the same

[halcyon laurel]

how 🥲

[gritty elm]

why you are getting directly reference to first person player camera like this?

[halcyon laurel]

its a widget with a slider

so this is the only way i know to get first person charaters camera

[gritty elm]

do like this

don't get reference from axis event

like this

it looks like you still needs to clear your programming and blueprint concepts

[dawn gazelle]

It's also bad practice to use values from one execution path on another.

[halcyon laurel]

i have done this to all my fpp cameras

i should replace them all right?

[halcyon laurel]

u mean the more than one camera i used?

[dawn gazelle]

Accessing the value from this cast...

In these two events

Eg. Are these DOFUpdate being called on tick? If so, the event that would trigger the cast won't happen until you fire the event where it exists (moving the slider)

[halcyon laurel]

@dawn gazelle@gritty elm i am realy dumb af , i am still learning cooding with cpp and blueprints

thats why am bad

Guys i need a little bit of help 😭, i'm trying to create a "server browser" (using advanced session) and i'd say it almost works perfectly, if i play it inside UE... But when i package the project it doesnt create the widget with the informations (like server name, current player/maxplayer and so on)..

Inside the DefaultEngine.ini i already put the settings needed

In the screen i marked green the things that works, and red (i dont know for which arcane reason) those that dont works 😭

Hello, I'm making a character than can shoot where i'm looking at. The problem is that it can shoot behind itself and i don't want that. I thought i could get the value of the angle of the fire point and make my character unable to shoot if this value is above 90 degree or under -90 degree relative to where my character is facing. But with this I'm just getting the rotation of my camera relative to the world and idk how to do what i want

[gentle urchin]

You seem to be breaking the loop on first creation? Is this intentional? To only show the first server?

[stable dagger]

yea i just want to test it to show at least 1 server, but it doesnt when it's packed

[arctic cradle]

Hello, all. Hope you are well. Had a question: which comes first? Save Game or Game Instance? I realize that without saving, the instance will be lost when the game quits-- but from my understanding, I should be storing my health, items etc in the GI. Should it go Game > GI > Save game? Is there a more common explanation I'm not getting? Just asking, because I just saw a tutorial and he was storing the health and levels in Save Game, where I figured I was supposed to be storing it in GI.

[earnest tangle]

only game instance remains between levels

so you either need to store data in there, or make some kind of other mechanism like using save games

Hi, do you know a tutorial or we teach skills to a trainer?

Or documentation

[atomic salmon]

You could use a multi box trace and then use the normal to the plane splitting the box into two parts to check whether each point lays on one side or the other

What would be the use case for that though?

[proper umbra]

Does anyone know a good guide for making an item inventory system similar to Castle Crashers?

[atomic salmon]

Better to ask in #multiplayer

[crisp geode]

Also did, thanks man

[atomic salmon]

Sorry can’t understand what you are asking

[sharp wraith]

What would be the use case for that though?
@atomic salmon buying skills from a trainer

[atomic salmon]

You mean within the asset browser? Not in the level. It should be possible with BP based editor automation, but I never tried manipulating sound cues with it. Need some research on that.

[atomic salmon]

Sorry that was answering another question (the one of box trace)

But I understand you need someone to run some trainings? You could post it in the job section

There are few other Unreal Authorized Instructors on this Discord. Maybe someone is available.

[gritty elm]

why you are using "Rinterp to"?. Use "Lerp rotator" instead and plug the alpha into lerp node

https://answers.unrealengine.com/questions/411604/rinterp-to-doesnt-work.html

[atomic salmon]

Ha. Got it. Completely misunderstood your question, sorry. You may have more luck asking in #gameplay-ai since what you are after involves behavior trees and the like.

[atomic salmon]

RInterpTo needs to be used on tick and Current needs to be updated at each tick for it to work properly.

[gritty elm]

Hi @atomic salmon, Yes exactly

[atomic salmon]

So RInterpTo does not work if… you don’t use it properly. 😉

[gritty elm]

right

[atomic salmon]

If you want to slide the door up you need to Interp a position vector not a rotation vector. As a matter of fact you just need to interp its Z coordinate.

You can do it directly from the timeline by driving the world Z location of your door.

[modest gulch]

I mean during gameplay. But I used soundclass workaround, fortunately I did not need to set like 100 sounds each with different volumes dynamically so that worked out.

[signal warren]

hi

is there anyway to make custom collision component?

i want to something function like this Collision Sphere but in a custom degree (like cutting a part of a cake)

[modest gulch]

I can think about indirect way - create fbx with collisions only (though I do not know if it will load correctly without mesh, you could always put cube there and make it invisible)

[signal warren]

thank for your answer

i have no knowledge or experience in modelling or anything like that tho

gonna find another way then

[modest gulch]

well then I dont know unfortunately

you could always learn basics of Blender 😉

I wouldnt be surprised if there is way to make custom collision meshes in unreal itself tho

[unreal token]

how do i add a 3 2 1 start to my game? after they press play and before the level starts

[modest gulch]

you can make simple collisions on mesh in UE editor

and does anybody know how to do the keyframe system and the trastlate and rotate and scale gizmos

if this helps it looks like this in game

i am but i wanna remake it

becuase im making an animation software

kinda hard to i only learned coding yester day lol

i was hoping there was way you could send me to recourses to help

the only reason im learning to code i to make this

if i could i would hire people for free

i wouldnt need to learn to code this since im an aimator

not a coder

thi stuff to complex for me lol

i wanna make my own animation oftware

so i can have all the features i want

to help witht he progress

if i could i would use control rig but control rig never works for me

so

oh

umm

yeah ik

if control rig want so bad i wouldnt need to deiging a software]

i cant get ik 2 work with control rig

thats the only thing

ive watched them

but the mesh messes up so badly

it sometimes scales or it moves weridly or it disappers

oh ok

lets hope it tell me how

watched that one

i have before

i jut got ingorned

[heady burrow]

How do you get a reference to a spline mesh component

added using

do I need to manually store them in an array to then access them when I loop trough the spline?, seems a bit convoluted

[tight schooner]

@heady burrow you can store the "return value" of that node however you want, but an array is the most straightforward approach

[heady burrow]

seems kind of strange

[fleet cedar]

How can I flip a range of 0-1 to 1-0

[heady burrow]

I would think that if you have a "spline mesh" component there should be a way to attach it to a spline

like, having slots

oh well

[daring vapor]

Am I misunderstanding how to use the == node? Ultimately the goal is to have an event fire when a specific actor crosses into a volume. So my though is to use an ==. Check out the video to see the issue I'm running into. All help is welcome. Many thanx.

[errant snow]

Uh: output = 1.0 - input?

[silk hinge]

Hey I'm strugling with something to look for a specific Item into the inventory system i'm using.
I want to look into in to find a specific actor but I dont know how to loop into the inventory to find a specific item I came out with this but This is not working
Probably by the fact that I dont look into the Grind widget or something ? To be honest this kind of codes with maps and array is beyond me, i'm trying tho 😄

[tacit void]

I could be wrong, but I think it's checking a specific instance of that actor. So even though the object class is the same, they are different objects. Have you tried casting the object to ThirdPersonCharacter instead? That way if the cast is succesful, you can do one thing, and then assume it is not of that class if the cast fails?

[daring vapor]

Hmmm, interesting. That could work, though for the end goal I would like to avoid casting if I can. I'll give that a try. Thanx. 🙂

[grave swan]

How do you switch between sublevels?

[daring vapor]

In game, or in editor?

[grave swan]

In game, i want it so when the player collides with an object it seemlesly transitions in real time from one level to another

[daring vapor]

I ended up using the "Actor Has Tag" trick to make it work.

[daring vapor]

You can use one of these

This will allow you to stream in a level

Or...

You can create an Actor Blueprint that opens level (see below image)

This second one will unload the current level your player is in, and open the level you want. It's a clean wipe, so beware if you have any items saved you will want to load them in as you load in the new level.

Hope that helps.

There are a few other ways to do this, but these should do the trick.

[mossy bronze]

Any reason my character wouldn't be moving in the direction I'm turned?

Here's my character BP

found the solution here https://answers.unrealengine.com/questions/438450/view.html

[azure sparrow]

#fab

[peak crater]

how do I set a scene component to not move with the player?

I want this LoadoutSpawnPoint to always be at a given world location

[mossy bronze]

Why isn't this interpolating over time? I'm confused... It kinda just dampens my zoom amount (the zoom speed * CameraZoom axis value)... I'm trying to smooth the change out, but instead it isn't doing anything other than lowering my zoom amount

[surreal peak]

Hm I think you can cut the interp out of this

Maybe

[mossy bronze]

How's that?

Maybe some mathematical function to smooth floats? I know linear interpolation, but it holds the same issue... Maybe I just don't know how the Get World Delta Seconds function works

[wise swan]

is it possible to access FJsonObject in bp?

[mossy bronze]

even tried putting the interp in tick... this is extremely frustrating. what am i doing wrong?

Am I somehow supposed to recycle the return value of the finterp to function into itself? If so, how? Would I just add the output (as a referenced variable) to the zoomtargetvalue variable?

ill try it

if it doesn't work, i think im giving up for now

[peak crater]

I need to be able to access it from the player so I can move inactive weapons there

Basically on equip/unequip I move weapons between that spot and my hand

I figured it might give me a small performance boost if the weapons were just stationary when not being used

Instead of following the players around the map

But maybe not

I guess each map could have one of these points and I just get all actors of class to grab it from my character

[opaque blade]

i think there is an blueprint function library on the marketplace, other than that no - atleast in 4.26

[opaque blade]

the output should be the new target other than that it just does a single interpolation step

or use a Lerp for Current to Target and increment the Alpha each tick

[opaque blade]

you can set the location to absolute in the Transform in the Details Panel,

For more advanced solutions (but this one would require a tiny bit of C++) I would advice using a subsystem for that spawner - as they are easily accessible in BP (even player) but are more decoupled

[peak crater]

Oh nice ok I’ll read up on that

Do you think it’s worth doing/makes sense?

[opaque blade]

depends on scope and type of project

[peak crater]

Say I have 32 player mp matches

[opaque blade]

reading into it is definitely worth it though

its not about performance just about code quality and structure

So I want to make my static mesh component glow. I already have a material and also made a postprocess material named glow. Nut what I want to do is make it glow on a curtain time. Do I need a sequencer to make that trigger at a time?

Hi everyone, i struggle extremely with a BP problem, where i use a basic score system with destroyed physic actors by a rilfe. But whatever i try to do, its counting also the destroyed actors by a triggerbox or life span that i dont want.
My BP setup:

1. Character BP - Fire Weapon Control
2. Weapon BP (child of Char) - complete Fire Weapon Interface Function & Destroy Events of the targeted physic actors
3. Gamemode BP - doing the math to count the points
4. PhysicActor BP (no direct relation to Char/Weapon) - updating the score by a Binded Event on Destroyed
   //I should have put the destroying function directly into this actor, but I dont know the workaround without messing everything up
5. separate RandomActor SpawnerBox BP is spawning the physic actors
6. separate DestroyActor Triggerbox to cleanup the hidden physic actors with Begin Overlap Function
   -> Is there any way to prevent the DestroyedActors by the Triggerbox being counted too without messing everything up?
   I have tried it with e.g. a boolean check, score updating in the Weapon/Char, but the relations are still not working. After a full day trying to fix it I reached a Trial and Error point without any success yet. XD
   Hopefully someone can give me a hint to make progress with this issue. I could post all the BPs and Sub functions here but i think its a general relation understanding issue.

[brazen stirrup]

Hmmm idk then

[south merlin]

in your AI controller, create the random values you want. (I guess a world position. You could get a random point around the player and save that as a variable). Then in the task, just get that variable and use it for the initial face player.

Any Ideas ?

[gentle urchin]

Are you sure the item is valid ?

Get item class requires a valid input. Looks to be a custom function, and if so, it could contain the isvalid check aswell if you want

[crimson hornet]

Does anyone know what I need to add at the object of the cast to bp enemybase? I tried pawns and actors but it doesn't work.

[crimson hornet]

this is for setting target points for the AI

[jaunty dome]

thanks that worked

[south merlin]

You need to give it the object for the cast to work. So you need to get the object you spawned and cast it to the enemy base

[crimson hornet]

I tried this but it still doesn't work.

[south merlin]

check to see if the cast if failing

[silk hinge]

hey you were right about the is valid,I have some other errors but related to the fact that animations get fired even without a mag ^^
So thanks Branch is no longer buggy

[rugged wigeon]

I'm looking to create a "cover" system where players can post up against a wall corner and peek out / hide on predefined slots. I'm wondering what the most reasonable way to handle this is. Specifically how to add these slots to my objects. Everything can be a prefab. So the "cover slot" will basically be a box collider and a few stateful variables.

Is there any way I can attach this as a component to actors directly? I'd prefer not to use child actor components.

[frank salmon]

hey, does anybody know a possible way to fix an issue?
I have a character that is rotating based on my mouse position
I have a condition to make it rotate only if can rotate, my issue is that when i play a full body animation montage i would like the character to stop rotating and the way I am doing it does not work

[rugged wigeon]

where's the montage

[frank salmon]

and this is what I have on anim montage

[rugged wigeon]

use play montage. Disable rotation on the first pin (immediately) and enable it on completed

Possibly on interrupted depending on what you're doing

[frank salmon]

I am not using any of the character movement rotation variables

that shouldn't matter, right?

[rugged wigeon]

I can't see in your screenshot what you're doing after your montage call, but I would have assumed you're setting "Can Rotate" to False

[rugged wigeon]

Don't use notifies like you're doing. Use the node I showed you. The first pin can replace your notify at the beginning. The "On Completed" node can replace your notify at the end.

If you want to trigger a notify, make sure it's a "Montage Notify" when you add it, and handle it based on the On Notify Begin pin instead. I find calling notifies by name to be pretty terrible. You can switch on the notify name pin if you have to.

[frank salmon]

Yeah, plenty of issues rise with those as far as I can see. 😆

Thanks for the help

[subtle nova]

Quick question (I hope). I'm trying to figure out how to reference an Actor Component that is on a Child Actor Component of a BP. Is this possible?
I have a BP that's meant to do some stuff.
That BP has a child BP inside it.
That child BP has an actor component that I want to talk to.
I can't seem to figure it out.

[ionic glacier]

Hey, I am making a rig of a car using the plugin control rig, with ue5. I 'am trying to create a boolean controller that enable or diseable headlight. But the values that i set in the rig in the sequencer, like dont affect the boolean, + my construction script dont update on rig modification (like setting the boolean value). I've already enabled "Run construction script in sequencer" in the class settings tab in the control rig window.

[rugged wigeon]

child actor component -> get child actor -> cast to (class that it should be) -> get (whatever component you want)

basically the child actor component is just a container. Calling get child actor returns the actual actor.

[trim matrix]

Whats a good way to move a character or enemy a certain distance?

Launch character ia buggy and has no way to change parameters

[rugged wigeon]

launch means like literally launch them with physics

do you want them to walk somewhere?

[trim matrix]

Ahh

Nah like a knockback or charged attack

[rugged wigeon]

launch could be a decent choice. What do you mean you cannot change the parameters

[subtle nova]

I tried that but it fails the cast because the component inherits from ActorComponent not Actor.

[trim matrix]

Launch kinda sucks tho, cant change speed or distance

And its wonky when youre moving

[rugged wigeon]

@subtle nova show me the graph including the list of components. If Person has a child Actor Sword and you want to get the Sword's collider component.

Person.Sword_Child_Actor_Component -> Get Child Actor -> Cast to Sword -> Get Collider

You do control the speed. It's the magnitude of the vector.

[trim matrix]

But speed is tied to distance

[rugged wigeon]

Launch works, I assume, as "launch the character in the direction of the vector at {vector.length} cm / some unit of time"

If it feels bad, make sure there's a bit of upward velocity so they actually get off the ground, if only for a bit

[frank salmon]

@rugged wigeon your way worked fine. much appreciated

[subtle nova]

This is what it's doing. The Button is an Actor BP that I added to a BP, and it has an Actor Component on it I'm trying to access.

[rugged wigeon]

You want the base interact component that is on some sort of button right?

[subtle nova]

yeah

[rugged wigeon]

Button BP -> Get Child Actor outputs the Button. The original thing is just a child actor component. Like a container for the actual button.

So you need to cast to the button class

then get the base interact component of the button after it has been casted.

[subtle nova]

Interestingly, I can't call any of the functions on the button from the parent bp, which could be part of the issue. I just drag-and-dropped the Actor into the parent.

[trim matrix]

Isnt there a better way tho?

What node can I use othet then launch?

[subtle nova]

gotcha, I'll give that a try

[rugged wigeon]

ehhh idk. I would use launch. Add force might work.

[subtle nova]

Seems like a roundabout way of doing it, but I seem to be able to access stuff now. Thanks! @rugged wigeon

[hybrid ether]

Hello! I have level with day/night system in my level. (Sun rotates). And I have some dungeons and those are different levels. If I go to dungeon and come back to main level sun rotation of course reset. I want that sun rotation saves trough levels. What would be best way to do it? "I go to dungeon when morning and be here 5 seconds and come back to main level and there are night" 😄

Saving it event tick would be really bad for performance I think.

[tight schooner]

@hybrid ether Maybe have the GameInstance class keep track of the time of day, because that class persists between level loads

[hybrid ether]

Thanks! Ended up doing it like this 😄

[brisk mortar]

Is there anyone on here that can help me? I'm starting with blueprints and i'm trying to recreate this tutorial,
I want my player to look in the direction of the mouse but it just looks at a single point on the map https://www.youtube.com/watch?v=fOjAaskzquc

all it does is this

this is the blueprint code

in player controller

[proper umbra]

Hey. I'm trying to make a function that spawns multiple projectiles at once, and have them move in multiple locations. However, when I play the function with the forloop, all of the actors are spawned with the same transform.

[left fulcrum]

Hey there, I am working on something but the thing broke and I cant figure out why, it was working just fine but I realized I was using the wrong sky (I made my own so I was referencing the wrong thing) but now it is saying that the object I am trying to reference is none and I dont understand why. A simple variable made to be an object reference for BP Sky Sphere and it just says it is referencing none everytime

It is supposed to be a weather system and it worked fine until this broke, anyone got any ideas?

[midnight kiln]

@left fulcrum Where is sky being set? I also see a variable for new sky in there, is there a chance that you are using an old variable?

[left fulcrum]

No the new sky was an attempt to fix things, but that might be the issue, I am looking and I think I deleted where I set the sky by mistake

[brisk mortar]

i cant believe i had to go back to june of 2020 to find an answer

and the answer was just times something by 5000

[midnight kiln]

Did you add a print node to check if all your rotations are the same? The issue could possibly be in the projectile itself, depending on how it is set up, they could all be being sent in the same direction.

[gritty elm]

Yes because you are giving location of sphere for spawning, no matter how many times you spawn, it will always spawn at the sphere location

well, to spawn at random location, you can do this

add random integer to x,y,z coordinates, max and min random value @proper umbra

the other method is to multiply the for loop index with sphere x,y,z location

[trim matrix]

I have collision question

I have 3 static mesh and one player and I wish that each sec pass information actually which mesh it is currently being in contact among the 3

[broken wadi]

s + click (sequence), d + click (delay), f + click (for each loop), g + click (gate), c + click (comment), b + click (branch), n + click (do n), m + click (multigate)

but why doesn't p + click make a print string node 😦

[hallow sentinel]

Question about 2.5D games. Currently using the default character and I am running into issues if they are not facing left/right. Running into some goofy interactions if they are looking towards or away from the camera. Any ideas on how to lock their rotation based on the last direction moved?

[zealous moth]

@hallow sentinel in the character class i dont remember if it is in the movement component but you can set the rotation speed for turns. Set it real high

[gritty elm]

save last direction into a variable for later use, and if it is your character, then maybe disable yaw, pitch, roll input, make a bool variable and then set that variable to true when you want to lock?

[zealous moth]

@broken wadi iirc you can make your own shortcuts in the preferences

[gritty elm]

does it single mesh? and have 3 mesh objects?, so you need to set collision for your mesh to complex :https://docs.unrealengine.com/4.26/en-US/InteractiveExperiences/Physics/SimpleVsComplex/

[orchid star]

Is there a way to force a texture to be power of two in the editor

we have an issue with someone that they have tons of textures with high res

but not power of two

so we cant reduce them via editor

[earnest tangle]

Do you not have the originals?

It should be possible to export a file from the texture if you right click, it's under asset actions or something iirc

[orchid star]

probably not, needs manual export/import

yes I know

but there is around 1.4k texture

so

yeah

[earnest tangle]

oof :P

I guess it might be possible to write a script to do it in editor, but it would probably be quite nontrivial

[zealous moth]

You could make a mastrr material and make the texture a variable parameter. In the material change the resolution

[orchid star]

but thats not the point

shitty optimized project

that loads entire project

causing high ram usage

[zealous moth]

Use an atlas for texture then

[orchid star]

so trying to cheat it with lowering the required memory

[zealous moth]

Power up photoshop and stitch several textures together

@orchid star when you optimize is it the cpu or gpu that hogs most?

[gritty elm]

Yes it is possible to apply these settings to all textures at once

[mild pecan]

Anyone have thoughts on how to get the average velocity of a motion controller over a few frames?

[gritty elm]

@orchid star

[zealous moth]

@mild pecanmake a map a t 0 and tx and update each time. Get the value.

[gritty elm]

there is an option called "Bulk edit", if you select multiple assets, you can do this, and change any properties of multiple assets with single click @orchid star

[orchid star]

that was not the problem

tried it anyway

and crashed yay 😄

no worries

[gritty elm]

well, try to select some assets, not all at once. but this is how you edit multiple assets at once.

[orchid star]

what I meant wass

I have bunch of textures which are not 1024x1024

such as 633x722

and I cant change their size via unreal because of this

I was looking to make them clamp/ fit automatically into the closest power of 2 or something

which there isnt

an option for I think

[earnest tangle]

there's a checkbox called force power of two, have you tried that?

[orchid star]

ooh

where

[earnest tangle]

I think it's in the texture's settings?

unless I was imagining it lol

[gritty elm]

there is already option for power of two

[earnest tangle]

ah yeah that's the one I was thinking of

[orchid star]

ooh

thanksss

thats nice

but

how to center it now 😄

[solemn dust]

is there any built-in, or easy way to evenly distribute x objects within a circle?

[heady terrace]

I do not know of any built-in solutions. The best idea I can come up with is to use radial coordinates whose origin is the center of your circle.

[jaunty solstice]

Have a fairly complex Construction script that instances thousands of static meshes at once that should be totally random but sometimes 'twins' happen. ie 2 of the same static messh are instanced side by side.
I thouhgt if i could somehow slow down the instancing process It would help greatly in debugging.

Is there some way to insert a delay in a For Each loop?

[heady terrace]

Why not use breakpoints? Put a breakpoint in the for loop and cycle through each call to the Construction script?

Learning how to use breakpoints is important.

[solemn dust]

Thanks. I found this online: https://medium.com/@vagnerseibert/distributing-points-on-a-sphere-6b593cc05b42 which is good enough for me (there is a mention about 2D distribution)

[heady terrace]

Ok, so I have a problem in my own work. I use a Timeline to move my character when a mantling animation runs (I can't use the root motion unfortunately), and it works properly but the character can't move in the x, y, or z direction for the next few seconds after the Timeline is complete. I know it is reading my inputs properly because the animations run correctly. I have also set the character back into the "Walking" Movement State, too.

[solemn dust]

do you set the movement state back to walking when the timeline ends? maybe your timeline is longer than you think? i usually have problem with that, because the timeline is not over when it reaches the last keyframe, but it has a length you can set

[heady terrace]

A length you can set? That's probably part of the issue (or the whole issue). Where can I set it?

[heady terrace]

https://tenor.com/view/the-simpsons-homer-simpson-good-bye-bye-no-gif-5173989

Ahhh, I see... I was too busy to notice it was there. 0.0

I was assuming it would be in the curve object's UI or something.

Yes, everything works now! I had a feeling it might have been the Timeline, I just was not sure!

[steel sequoia]

#graphics message

^^

[supple dome]

i think you will have to rethink (or clarify) your rules, the only place the same distance from two points is a line in the middle of them, and if both are at the same place, any point in the world is the same distance from both

now if you actually want that, a perpendicular line between two points (p1 + p2) / 2 will have infinite points that are same distance to both

[quasi frost]

When I add a widget to my uniform grid why is it putting this massive space between them? (See cards in hand at bottom of screen)

I'm not adding it to the grid in any special way

Ok figured it out, the overlay it was inside of needed a scale box to contain it

[drifting bronze]

im trying to get a widget to pop up on screen when i hover over a button (just press E to interact) this is my current blueprint but its not working and im not quite sure why

anyone help me?

[dark crow]

Uhm, cause it's not connected

[drifting bronze]

ive connected it every which way and it wont display

[dark crow]

Exec Pin

[drifting bronze]

im trying to get it to display when the linetrace overlaps the collision box

[dark crow]

It's not connected on the execution flow

[drifting bronze]

in another test it was

i sent the wrong picture

if i connect it it displays after i press e

i want it to display as soon as the crosshair hovers over the button

[dark crow]

Then you need a check on tick or so, constantly fire a trace that constantly checks if it overlaps something

[drifting bronze]

alright one min

like this?

still not working @dark crow

used the wrong line trace but stull not working

fixed it now but wont display

[dark crow]

You sure it's reaching the target atleast?

Debug line hits?

[drifting bronze]

ok i think i fixed it

now i need it to remove from the screen lol

[wise edge]

Hi im trying to recreate the camera from top down games like alien swarm or the ascent where the mouse moves towards the location of the cursor. This code below is working but when the magnitude gets high, (ie: the mouse is far away from the player) The camera becomes jumpy. If i reduce the multipliers that i've got around this logic, it may smooth out but barely moves.

Can someone help me improve this logic?

Also, when i open up 4 clients, the camera becomes super jumpy with this logic enabled

[drifting bronze]

@dark crow it displays now but i cannot get it to remove from screen

[wise edge]

https://www.youtube.com/watch?v=gDunr1Vxqpg&ab_channel=ESCalation

[drifting bronze]

im getting accesed none at remove from parent

[wind void]

if you are using this, BP still, that is because Return Value isn't set when it loops back around and finds out it needs to remove it.

few suggestions to remove your widget,

[drifting bronze]

yes please lol

i am beyond frustrated with this

it should be very simple

[wind void]

if it's the sole widget thats being shown the easiest: Remove all widgets

[drifting bronze]

it is not

i have crosshair and HUD etc

that will not work for me lol

[wind void]

Make Return Value a variable, and then access it later.

You prob want to check if My Widget is valid before you remove it, just in case SOMEHOW it trys to remove it twice.

[drifting bronze]

like this?

[wind void]

You need to SET Interact Widget

right after, or right before Add to Viewport

[drifting bronze]

liek that then?

[wind void]

Yep

[drifting bronze]

didnt work

still displaying after i look away

i want it to show when i hover over button, and remove from screen when i look away

thats what i have currently

[wind void]

ohhh

well,

[drifting bronze]

the vector math is just setting the interaction space so you cant interact from just anywhere

[wind void]

it looks like you are making a few hundred widgets

but only storing one

[drifting bronze]

HA

your right!

lmao

so how would i fix that then lol

im really confused now

[wind void]

oh, well

would you like only 1 widget being made?

or would like hundreds and just removed them all at once

[drifting bronze]

only one, but i need it to be made again if i mouse over again

this works but not if i want it to display again

wait!

i got it!

thats all i needed haha

god that was so frustrating lol

thank you for your help lol

[wind void]

Np

[wise edge]

Hey any chance of a hand with this my code lords?

[craggy crow]

Anyone know how to prevent a slider to get higher values but it can go lower ? Thanks! 🌴

[plucky fractal]

Is there an event or function I could override for when a widget becomes visible? I want to select the first child of a scroll box each time its made visible.

[twilit heath]

construct

@plucky fractal

[plucky fractal]

so if its collapsed, then set to visible, construct is called again?

[twilit heath]

think so, it gets called when added to a parent even if not instantiated just then

easy enough to test

[plucky fractal]

looks like it gets called when the widget is created, but if you make it collapsed, then switch back to visible it doesn't call it again. perhaps i could make a function and just add that in after i set it to visible again

thanks anyway 🙂

[twilit heath]

yeah, wrapping its set visibility is fairly simple

and it will work

[plucky fractal]

that's seemed to have done the trick, thanks again

[eager field]

hi so i have normalized this float value to range 0.0 to 1.0 for a reason, what I wanna do is if the return value is high then I want to convert it as a lower value and if the return value is low i want it to be high, is there a way i can do that??

[gentle urchin]

like inverting it?

regular one minus 🙂

1 - return value

if return is low, it will stay high. if return is high, it'll go low

[eager field]

yes

yeah such an easy thing

my bad

thx

[outer goblet]

Hey guys, wonder if anyone might know what the problems is. For my project i been playtesting win/lose conditions endlessly and in editor everything is fine but when i package the project everything gets messed up. What can cause this?

[serene galleon]

Does anyone have any idea on how I can return to the distance from an actor INSIDE of a volume to the nearest edge of that volume?

[earnest tangle]

There's a million things. You'd need to explain precisely what behavior differs between PIE and packaged, and how it differs

[earnest tangle]

Not sure if it's the most efficient way, but perhaps you could treat the edges of the volume as planes, and calculate distance to plane

[gentle urchin]

location of actor - location of volume gives you the actors relative location to the volume
then you can check the bounds of the volume to calculate which edge is nearest, and return that, or its location, as needed

[earnest tangle]

^sounds better than my idea :)

[outer goblet]

Basicly its a simple best out of 3 race. After each round the winner is determined and the appropriate music is played. In pie its all perfect but in package round 3 messes up. I have a simple small melody playing after round 1 and 2 and if you or the ai win then a win or lose track is played, After round 3 though only the win/lose track must play but in package the somple melody and the win/lose track plays.

[earnest tangle]

interesting, nothing really stands out from that as something that has been a problem with changes in packaged 🤔

you probably should add some debug logging into it, packaged builds should still produce logs

[outer goblet]

I have a feeling its to do with tick. I created an intro widget with animation which i spent some time working out when to show and hide widgets based on the music. but when i do the package its slightly off

And i'm guessing that becuase i'm determining winner on tick then its probably not setting its sets too late or something. i think i saw something about framerate and tick somewhere but cant remember.

wait. Let me add a fade in and delay before the intro starts playing. Maybe that will help.

[broken furnace]

Anyone have time to help me figure out why my exact replication of a tutorial isnt working?

[gentle urchin]

How about using animation with triggers instead? maybe its alot more work tho, so possibly not a great solution

Like for the intro you'd start an anim montage on the "main camera", which would have triggers for starting the music, stopping it, moving over to the actual player camera, starting the lap , hiding widgets etc

Also, the goal probably should have a collision volume and react to overlap instead of checking on tick?

[outer goblet]

It does use overlap but i use tick to set the bool in gamemode. Gonna take a closer look at the win/lose in round 3 cos it seems thats the only part that has problems. winning or losing the event in round 2 is still fine but if its tie you go to 3 and then inpackage thats where it goes wonky

[gentle urchin]

How come tick and not event driven if you're already triggering from overlap?

Nvm that i guess, i just imagine it being a potential issue

[outer goblet]

I'll figure out somehow. TBH it took me like three days to get the stopwatch to work right and it was a serious headache and i think thats where the problem ibeing created. Too much to calculate and bools to set on tick once the overlap is triggered.

I dont hasve enough time to redo it so gonna look at using a delays or something in round 3 or set the bool another way.

[limpid saffron]

Is there any shortcut way to insert keyboard events like for 'E' key, don't wanna search in the list for all letters, there should be fastest way!! (eg. press B left click give you branch node!) thnks..

[broken furnace]

Input actions^

[outer goblet]

Thanks for helping 🙂

[wind void]

Hey, I coulda sworn there was a BP node that let you run quick animations on actors or components, like rotating it 90 degrees into a .5s animation. Anyone familiar with that?

[boreal ether]

You can type "e key event"

I would recommend adding custom input bindings in your project settings instead of using specific keys though

[limpid saffron]

@boreal ether thanks man good one

[limpid saffron]

any specific reason? Can you please explain why a little bit!

[boreal ether]

If you plan on releasing anything it makes it easier to make a menu to customize key bindings

If that doesn't matter to you I guess you can do either

Or if you want to release for multiple platforms you can use the same event

[limpid saffron]

actual goal is secret key combination to pop up secret image on the screen

[boreal ether]

If you need to use those specific keys then it's fine

[limpid saffron]

look like that stuff

@boreal ether thanks again

[serene galleon]

Not sure if I fully follow. My trigger volume is fairly complex in shape so the actor bounds is not a reliable way to accurately get the closest point.

[brazen stirrup]

what does the clamp node do?

[serene galleon]

Forces the input to the specified min and max at output

[gentle urchin]

Is the shape uniformed?

I'd think its not since you said "complex" ... if so then true, my suggested method wouldn't work

[brazen stirrup]

arrrigatto

now can I ask something about the animbp here?

[serene galleon]

It is not 😦

[brazen stirrup]

I want to blend a control rig with a locomotion, what blend do you think I should use?

[gentle urchin]

Not sure if I can think of many other methods.. tracing for it is not very practical..
Why such an odd shape if i may ask?

[brazen stirrup]

like, if I add my ctrl rig to a additive blend, the manniquin becomes a titan

[gentle urchin]

Is it possible to make a "variable pointer" in bp?

Or do i have to read it from its original location?

[brazen stirrup]

uuuh

idk

have u googled it?

[gentle urchin]

tried, but its not easy to find 😛

mostly they show results about setting and updating variables

Seems it must be with c++

[brazen stirrup]

huh

I think you can use a bp in cpp though

like make your bp as far as it can go, and when needed, convert the variable to cpp

or vice versa

[gentle urchin]

Yeah

It's not life or death needed, just sometimes seem to be handy 🙂 altho pointers can be frustrating to working with aswell

[brazen stirrup]

do u know anything about animbps?

[true valve]

So I 've an item blueprint which when I pick it up , I want to store it in a variable then destroy it.

How do I create another instance of that actor

[brazen stirrup]

idk lol

another instance of the actor u destriod?

[gentle urchin]

Store a reference to it? Or its class?

[brazen stirrup]

like to populate your game with the item?

[gentle urchin]

Not that much, also I think this is more suited in the #animation tab

[true valve]

I tried storing its object ref but when I delete original then the ref is lost as well

[gentle urchin]

Because the object ref is a pointer to an object, which you destroy

[brazen stirrup]

welp, no one replies there

[true valve]

sp what's the solution. store class ref?

[gentle urchin]

Either save its class, or save its data if the data is beyond the normals for that class

[brazen stirrup]

make a variable for the object, give it to your char class or something, then store that value in another one so it doesnt get lost

[true valve]

Let' say I store its class then how do you get the object ref

[gentle urchin]

By spawning the actor by class again

[true valve]

maybe GetActor of class- I don't want to spawn it into the world

[gentle urchin]

Not get actor...

the actor is already destroyed

If you want it back in the world, you must spawn it

[true valve]

No i don't want it back. Using the ref, I want to get some info from that actor such as animations, etc to play them

[gentle urchin]

If the class itself holds these , then you can get the class defaults

[brazen stirrup]

does my solution work for u @true valve ?

[true valve]

No - squize's solution works.

[true valve]

it works but I get Get Class Defaults has an unsafe connection to the ...

[earnest tangle]

Depending on what you're doing you could just not destroy the actor and simply hide it

[true valve]

not an option

How do I get rid of the warning though

[earnest tangle]

What warning are you getting?

[gentle urchin]

check if the class is valid probably

[fallen glade]

does anyone know why my project takes a long time to play the first time each time the engine is opened? Can this be alleviated?

[gentle urchin]

I've noticed the same thing !

Curious to what happened there...

[fallen glade]

my bet it's that it's loading everything the first time or something like that, I do not have a brand new PC anymore so could be that

[gentle urchin]

That could be, and my pc is in the same condition as yours (or worse), but even so! It was not like this not long ago

I can't really recall when it started tho..

[fallen glade]

in my case it's getting worse the more I add to the game

[gentle urchin]

Game in total, or the currently selected play map ?

[tacit maple]

How do you specify what type of Nav Agent a certain pawn will be? Currently I have two agents Large and Default. But my smaller units seem to be pathing using the large agent. Am I missing something? Thanks.

[fallen glade]

the best size it assigned based on capsule size

this can be changed in the capsule parameters (I think)

[tacit maple]

@fallen glade thanks, I read about this but it seems like the capsule size isn't making a difference for me. My capsule sizes are matching the default capsule size, but they still picking the large agent which is roughly 300.

Perhaps it doesn't pick the closest but rather a range so anything <=144 is default and anything 144<=x<=300 is considered large? I'll try play around and see what happens!

[fallen glade]

yeah play around, there are also some inconsistencies as far as I remember, some numbers take into account radius, others diameter, again, might be wrong I haven't touched that stuff in a while

[steel sequoia]

anyone know how to "AllowDebugViewmodes"?

in the packaged version of the game?

I found this to no help "https://docs.unrealengine.com/4.27/en-US/API/Runtime/RenderCore/AllowDebugViewmodes/2/"

[fallen glade]

I would like to know too... I mean, there are ways around it though, what view do you need?

[void needle]

does anyone know, is it possible to make actor undestroyable by any conditions?

[gentle urchin]

What do you mean exactly?

[void needle]

one of my actor destroyes everything it touches, but can i make one of my actor not destroyable for it

[gentle urchin]

The actor that destroys it must check for that actor and not destroy it if its that actor

i assume you're using some sweep, or collision overlap or hit

[void needle]

yep

ty

[gentle urchin]

you can also make it ignore the collision in the first place

[void needle]

i made it like this, but it doesnt work

[gentle urchin]

Is it the topdownchar you dont want it to destroy?

[void needle]

yes

[gentle urchin]

Then just connect cast failed to destroy actor,

and unplug the rest

[void needle]

ty, it worked

[zealous moth]

You can use the F buttons like F1 and F2, do you mean those?

[fallen glade]

no like metallic, base color etc, I know you can get there by using a custom post processing material but that's annoying to do

[steel sequoia]

@fallen glade I want to use unlit for the perfomance boost

[open peak]

https://i.imgur.com/FfMuCT6.png

how can i interpolate the segment's roll angle in a spline mesh?

[fallen glade]

I think you would have to disable stuff in code to stop the engine producing the the required buffers? I'm not sure, do you need this for testing or art style?

[steel sequoia]

cause it increases fps by 20

its for a performance mode

@fallen glade

[zealous moth]

Are you using a spline or a spline mesh?

[zealous moth]

then use the F1 F2 F3 keys. You can change the view also in the editor

[open peak]

Spline, but i figured it out by setting the start and end roll of the spline mesh component

[zealous moth]

ah good!

[steel sequoia]

@zealous moth i mean for the packaged game

once packaged debug view modes are inaccessible via console

it says see "AllowDebugViewmode()"

which is not a console command

[jolly island]

Hello, is it possible to trigger an event in the character blueprint when a task is executed in the behaviour tree?

[open peak]

Is it possible to raycast down and get the roll of the surface below?

the surface doesn't necessarily have a collision

[small token]

Do anyone know if there Hundreds inside array using struct trying use for each loop equal to equal by name then find specific name can cause game freeze about 10 seconds then finally load? Either if it there no name found. Still 10 seconds specific. Is there another way not to use For each loop. It need to search every struct

[proper vale]

Hi guys!
Could you tell me please,
How can I find the reason why i can't see blueprint library in a list of blueprint libraries on Right-click in a blueprint?
I'm trying to find the Take recorder Blueprint Library and use it for my project, but I can't find it

[light token]

Hello. I have a question. I spawn a blueprint but the blueprint has a public variable. Is there a way to set that variable when the actor spawns?

[bright frigate]

Begin Play?

[light token]

Can I do that? It needs to be set to another blueprint instance

[earnest tangle]

If you need to set is when it spawns, you can set the variable to "expose on spawn"

this will make a pin for it in the spawn node

[light token]

I already got it by using get actor from class.

Maybe this works

[earnest tangle]

I'm not quite sure what you mean

If you're spawning a new actor, then it wouldn't exist so getting it by class wouldn't do anything

[light token]

Nah this wasn't working

I have two borders

which need to rise up

I have an item

if it drops on a plane

it should raise the borders

but I cant get a ref to those borders

[earnest tangle]

well provided the borders exist when it's called, get actors by class with the border class should get them

[light token]

Hmm it isn't working. I;ll continue debugging
