[twilit heath]

or pur a movement component on a Pawn, it just can't be CMC

[upper adder]

Hey! How can i find out if my pawn, not character, is on the ground or in the air?

[vocal elm]

you will have to make that logic your self, since that is a function specific to the character movement component. You could add a character movement component to your pawn blueprint, then it will give you access to that function

[olive sedge]

I have a string in an actor and I set it on the server, Replication is set to Replicated but on the client the string is empty. Any ideas?

What the hell. WasRecentlyRendered output false, if I load some sublevels and have some fps drops..

[upper adder]

Okay thanks, guess i will do that!

Or maybe just a linetrace straight down and then check the length..

Good morning guys, I am working with AI for our enemy. As I don't have the model atm I'm aiming to use temporary skeleton and animations, is it possible to rebase the anim BP onto another skeleton later on?

[grim gorge]

Hello! A couple of very basic blueprint questions - say I want to insert a node on an existing cable (for example, add a branch to an existing Exec connection). Is there some way to insert the node without having to reconnect everything? Like for example in blender you just drop the node on the cable and it inserts itself, but Unreal doesn't seem to work like that. And conversely, if I want to remove a node without breaking the cable (for example to remove a branch) is there a shortcut to do that?

[burnt anvil]

just drag out like this and place your new node

it'll insert it in between

following a tutorial , i can't find the item id pin he has here . i think he's using an older version or somehow inserted it and i can't find how .
here's the video , at 18:29 he has it while at 8:31 he doesnt . i can't seem to figure out how he added it . any help is appreciated ^^

@burnt anvil you have to make that variable instance editable and exposed on spawn

[burnt anvil]

Oh , thanks , i watched the video a couple of times and i managed to miss it everytime somehow ! still not even sure where that variable is lol

[weary jackal]

In widget

[burnt anvil]

oooh , found it . thanks alot !

[rugged walrus]

how can I take a blendspace or something from one of my project and put it in another?

[orchid garden]

right click the blendspace, click asset actions->Migrate, the next box will list all the assets linked to that blendspace that need migrating with it, click okay, browse to the folder where your other project is and go into the content folder and click 'select folder', then the engine will migrate the needed files over to the other project.

Note - when migrating some assets you will have to make changes to the project settings in order for them to work properly in the other project. Most people are nice enough to provide migration tutorials in this case for their items if your using store purchased items.

[sterile wraith]

how could i create an asset which contains a cyl and a text and place it multiple times within a blueprint?

[grave relic]

I dont see how this turns into a infinite loop, anyone that can help? 🙂

[ocean radish]

@grave relic because all it sees is a bool and while, so gonna loop infinitely, its not taking into account the released part, use somthing like a timeline or timer to change it, and take it away from being frame dependant

@grave relic currently the more frames you have the faster that item will rotate

@sterile wraith a cyl?

[grave relic]

@ocean radish Okey, dont know if timeline works but mabye it does for this, the thing im doing is rotateing a camera around the player, i want it to rotate left while holding Q and right while holding E

[ocean radish]

@grave relic

think that should do the same

opps add relative should be in the custom event

not off the timer

that will fire that add relative event every 0.1 seconds until released

you can change that 0.1 time lower if you want it to be smoother

[sterile wraith]

@ocean radish cylender or cube

[ocean radish]

@sterile wraith

just make a blueprint, then spawn it

[sterile wraith]

how can use that combo in another blueprint

[ocean radish]

how many you need to spawn?

[sterile wraith]

Depends on the data, trying to make a Bar Graph

[grave relic]

I get the rotation to work, but it dosent stop when released 😮

[ocean radish]

yeah it needs to be a clear and invalidate

sorry my bad was rushing it @grave relic

[grave relic]

Dont apologize 🙂 Thx for the help

[ocean radish]

@sterile wraith basic but will get the job done

can change the for loop, for a for each loop and feed it an array

[ocean frost]

Hey, guys

[ocean radish]

Hey

[ocean frost]

how are u?

[ocean radish]

good good, just killing time before work

[ocean frost]

same

[sterile wraith]

@ocean radish thx i will try it

[orchid garden]

how would i go about doing a line trace for a top down camera that keeps the camera angle but traces from the character in the direction they are facing?

[ocean radish]

@sterile wraith

[sterile wraith]

thx

[ocean radish]

np hope it points you in the right direction

If you need to do it at runtime, you'll need to do it in event graph not construction

[sterile wraith]

and if i need to change it 'live' i need to make an array right?

save the objects to an array*

[ocean radish]

yea

[sterile wraith]

btw, how did you get your lines with edges

instead of curves

[ocean radish]

ah thats a plugin called electornic nodes(its not free)

[sterile wraith]

oh

[ocean radish]

I just much prefer the look of them

find it easier to follow

[orchid garden]

this gives me strait out from the character which is fine for fighting, but i need it at the camera angle for interaction with objects:

[ocean radish]

Geeky, you trying to point it under the mouse cursor?

[orchid garden]

@ocean radish no mouse cursor, not a point n' click, mouse only controls the direction the character is looking

[ocean radish]

can you mock up a little image of how you want the linetrace to cast, as not sure on what you mean, from character but camera rotation

usually for top down, you would just cast in a straight line and make anything else in the scene thats interactable have a hit box thats on that level

[orchid garden]

if it was strickly top down the hit box would work but its not

[ocean radish]

so you could do a cone trace or somthing similar to make the line wider to detect but that looks to me like a higher collision box for tests would be a better soloution, as your not have to change cast for any other objects in the world

[orchid garden]

basically want the trace to do this:

[ocean radish]

thats how i would do it

[orchid garden]

that would work but it also supports third person view

[ocean radish]

then when you flip into third cast from camera

just make sure to ignore the player pawn

[orchid garden]

i got the third person trace working properly, just having issues with top down

[ocean radish]

the main prob you have is different assets, if there only gonna be ground level then add the cast from the bottom

[orchid garden]

yeah they won't just be from ground level sadly 😦

[ocean radish]

but if you plan on having them different heights in the world, gonna have some issues with trying to cast that wa

wa

way

gotta goto work, will try think of a solution hehe, got me wondering how now

[orchid garden]

hrm....

is there a way i could lock the rotation of the third person camera when in top down view?

[ocean radish]

prob is with that is you can interact with stuff thats lower further away, but get closer it can no longer see them, you aiming at a specific spot, and yea, can just set its rotation and disable the input for it

[orchid garden]

yep thats kinda what i want for the interaction (aiming at a specific spot) rather then a range

there will be a onscreen notify so they know they can interact with the object:

might just get rid of topdown... not the first issue i've had with it.

supose i could leave it as a look at type trace...

[ocean frost]

@ocean radish you are busy now?

[orchid garden]

then whatever they are looking at could be traced in topdown:

basically still using the third person camera for the trace while in top down.

im overthinking it.... I have a head cam that points at what the character looks at.... can just use that for both modes:

modifying the right vector for third person

[burnt anvil]

does anyone know what the order of the sequence node is ? i mean if i have a long tree in sequence 1 , then a single task in sequence 2 , doers that single task wait for the whole sequence 1 tree to finish before executing or does it do it simultaneously ?

here's my example , does the set health wait for the whole tree on the top to execute first or dies it execute at the same time as the first set child actor class ?

[orchid garden]

it executes seq 1 then 2, and so on each seq doesn't start till the other completes

[burnt anvil]

alright , is it fine if i use it to check if player is dead or not after an event tick node for example ? i m using the event tick to control the rotation of my character and want to add something that checks if player is dead or not .

[orchid garden]

i just use a branch check to see if the player is dead then execute a kill player routine:

when the player takes damage it runs that little function

[hollow drift]

Has anyone experience with Chess styled games? I am reworking my script to use individual Grid coordinates instead of the "XYZ Transform Locations". Any best practice suggestions?
I want to calculate everything based on the new Grid system.

[sterile wraith]

@ocean radish you still here?

[maiden wadi]

@orchid garden @burnt anvil Do at least be careful with sequences and latent functions. If you put anything like a delay or whatever on line one, it will hit that delay and start it, but then immediately start line two. Line two will not wait for the delay to finish before starting. Without latent nodes, you can relatively count on the order.

[orchid garden]

been staying away from delays sense you pointed it out earlier with the double tap 🙂

[maiden wadi]

I only ever use delays for testing. There's always a better way around using them.

[orchid garden]

found a simpler solution for my tracing issue, sense i have a face camera setup on the character that points to whatever direction the player is looking, im grabbing it for setting the direction and then using the booms position as the start point of my trace, can use it for both the third person and top down traces:

[vernal kindle]

Anyone found an elegant solution for Dyamic Data Tables?

I've got 1 struct for essential information, then another struct for specific classes with a reference to the first struct, ensuring all Data Table entries have access to the critical information (name, icon ect.) while allowing me to have separate DTs for specific items to avoid a bloated master DT (weapons, consumables, equipment ect) I thought my logic was clean and future proof but i've hit this roadblock. Its fine on the specific class side, because i can always just assume the struct of the class, but in a generic case where it needs to read a variety of DTs such as an inventory slot (which can hold many types of items) i'm stuck.

[orchid garden]

enum list in the first table to set what the second data table is then based off which enum is set in the first, grab the data from the second?

[rugged walrus]

This texture has the word 'smoothness' do I plug it into roughness?

[vernal kindle]

Yes, but invert it

[rugged walrus]

how?

[vernal kindle]

Use a one minus in the material editor.

[orchid garden]

sorta like what i did here with my sounds based of of what enum it is it selects the sound from the soundlist:

i think the concept would be the same

just make a struct list of the data tables for the different item types, then have a enum list in the main data table that sets the data table type, and the enum select should return the data table you want.

[stable fjord]

Hi guys!
I have a sphere component as a punch point and capsule component as a punch receive point
I added it to two players and I would like to create a custom collision channel to make punch point ability to overlap with capsule component only! I have additionaly other capsule component to overlap with another type of object, doesnt connected with punching

How to make custom collision channel only for punch and receive punch purpose? To punch comp could only overlap with receive punch comp?

[vernal kindle]

I think the issue i'm having is i can't read any data from the first struct if the dynamic input is the second struct.
So if in Struct1 I have the enum, but i'm calling the struct2 dynamically, i cant tell the editor "well i've nested struct1 in struct2, so just give me struct1's info" if that makes sense?

[orchid garden]

hrm... build a component to store stuct 2 in struct 1 then load the data into the component?

[tawdry wyvern]

Is there a way in blueprints to make some kind of temporary variable? to store the output of something for later use but not make it a full fledged variable?

[orchid garden]

you can in macros

just type 'local' then the var type (float, vector, int, etc) i donno if it works outside of macros

just checked, seems to be macro specific

[tight schooner]

@tawdry wyvern local variables exist in functions as well

[orchid garden]

persistant local variables do

any fuction can have a local variable if you add it via:

i may of misunderstood the question though 🙂

[tacit maple]

Hey, anyone know how to make a character move in all directions with the same speed? Its 8D motion and when I hold W, the foward speed is 500, but when holding W + D, for a diagonal run it drops to 353 for the forward and side speed, is there a way to maintain 500 in all directions? Or am I thinking of this incorrectly?

[orchid garden]

@tawdry wyvern you can add local variables that only store data for the functions / blueprint from here:

if thats what you were meaning 🙂

[tawdry wyvern]

not exactly. Here is what I am doing currently. I was wondering if there was a way to do this without actually making a MontageToPlay variable that is available to the whole blueprint and clogs up the "variables" list but is just sort of exists within the flow of this one event. Idk if that makes sense. I guess maybe if this logic was in a function I could make a variable local to that function

Edit: tagging @orchid garden because I forgot to use "reply"

[orchid garden]

i'd just collapse it into a macro and use then you can right click and type in 'local' with the varable type after and it will only be persistent inside that macro ( like @maiden wadi did in the double tap macro ) and won't clog up your variable list.

You can also make your own categories / subcategories for the varables to go into to make it a bit less cluttered, when you make the variable in the 'category' box in details you can type in your own category name for them to be placed in, if you want subcategories its maincategory|subcategory in the name list.

just incase im not explaining the bit in a macro good enough with the right click:

To punch comp could only overlap with receive punch comp?

[vernal kindle]

You might not need a separate channel, if i'm understanding the problem correctly, you could just process all overlap events between the two collisions, but only do something when a certain criteria is met;
For example, if the player is punching, set bIsPunching to true, which in the overlap event is hooked up to a branch that will continue with the rest of your logic.
So if the player is punching, and the collisions are overlapping, do the rest of your punching logic such as damage ect.

[stable fjord]

Yea

But this overlap event should only work between punch point attached to hand and punch target (kind of capsule, sphere)

So thats why I decided to create a custom channel

But i dont know why

[vernal kindle]

If you do want a custom collision channel you can make them here.

[stable fjord]

If I go back home I will show you everything. I have it done but I am not prettt sure that I did it correctly

30 minutes and I will back

[tawdry wyvern]

oh awesome this sounds like just what I am looking for thanks a bunch 😄

[faint pasture]

@tacit maple it is maintaining 500 already. 500 diagonal is 353 in each axis

If you had 500x and 500y your speed would be 707

[teal dove]

Hello, does anyone know how to rotate a springarm so that the attached component reaches a point on a sphere (without changing the spring arm length) ?
Both component and target position are on the sphere surface, so at the same spring arm length.

[stable fjord]

@vernal kindle I am back

I have following things set up

And I am not pretty sure thats works fine

cause Its not overlapping correctly

should I split it to Overlap reciver collision and Overlap maker collision?

And here I have following things

[shrewd dust]

Does anyone know how I would duplicate an actor asset with editor utility widgets and then set the static mesh variable of the new actor? this is where I am.

[earnest tangle]

you need to cast the asset to the correct type and the modify it I guess

so it would be cast to "YourActor Class" probably, and then you'd need to modify it from that somehow... not really sure but hope that helps. You might get more answers on #editor-scripting

[burnt anvil]

if i m making a simple ( very simple ) multiplayer game where player just walk around , shoot each other and collect coins from ground , is it fine to make it like i m making a solo game first then worry about multiplayer ? or should i keep some things in mind ? cause i have no idea about multiplayer and i m so far making it as a solo game .

my progrtess so far is that i got coins collecting working , shop set up and player walking around with hp , guns / shoot work .

[supple dome]

@teal dove bit late but (center - target) > MakeRotFromX, then set or lerp the rotation

[maiden wadi]

@burnt anvil If that's all you're doing. It's possible that it might not be that hard to port to multiplayer. Depends on how deep you get into the design though. Most cases it's best just to start with multiplayer in mind at the start.

[dusk flame]

Hey guys! I got a pretty simple blueprint question I think, but I'm struggling.

I want to create a structure in Blueprint, based on a struct definition in C++. I want to set members individually, like settings strings, ints, etc.

For some reason I can't get any sort of "editor" like that to open. Whenever I do "set this struct variable" it wants to take ANOTHER struct as input.

I can also "break" the node, but that splits an EXISTING struct into its components.

I don't find anyting to creat the structure from scratch.

[burnt anvil]

https://www.youtube.com/watch?v=IgR-PtaMloI&list=PL4G2bSPE_8um-3MIHOTwFwjWZdWO24S9O check out this , it helped me a ton doing weapons for my game

and now it's super easy to add more weapons

and now it's super easy to add more weapons

[supple dome]

@dusk flame i dont get what youre asking, you want a "make struct" node, or you want to make an asset of this struct on the editor

[vernal kindle]

It depends on how you're overlapping, overlap events won't trigger if they've already overlapped but you havent done anything with it, or the collision checks have been disabled.
If the collision combat preset is ignore everything, but overlap with combat it should work. If its not i'd take a look at your logic for detecting the overlap.
Although i still think something like this would be a better solution, but you know your project best so its just a suggestion

[stable fjord]

okay, I will check this out

[dusk flame]

@supple dome I need to creade a UMG widget, which takes a stuct of data (name, time, etc).

Normally this is done via C++, so it sucks a list of structures, and makes a nice widget list.

The difference here is I need to add one hard-coded item by Blueprint.

So the input is a struct, and I somehow need to tell it "this field is X, this field is Y"

I hoped I could "promote to variable", and then use the side-bar editor to set fields (like editing a struct), but that doens't work.

Do I need to make a new blueprint struct, based off the C++ version, and then get the path to that in the blueprint?

I'm sort of talking myself to a solution. I guess its not possible to create a struct inline, so I need a secondary asset, neigh?

[teal dove]

@supple dome Thank you for the suggestion! I guess I am doing it wrong?

[maiden wadi]

@teal dove Looks more like you need to get an angle between the target location and the current location and use that angle to rotate the SpringArm's Yaw rotation.

I think. At least that's how I interpreted your question above.

[supple dome]

its subtract not add

to get the direction from A to B you subtract B from A

[teal dove]

@supple dome Thank you, that works perfectly!! You are my personal hero 😄

Vector math is a nightmare to me 😅

Thank you so much!!!

[supple dome]

np

if the direction is inverted just swap them

[teal dove]

What do you mean with inverted?

[supple dome]

B-A gives one, A - B the other

[teal dove]

Ah alright 🙂

@maiden wadi And thank you too for the suggestion 🙂 🙂 you guys are great

[supple dome]

@dusk flame

I hoped I could "promote to variable", and then use the side-bar editor to set fields (like editing a struct), but that doens't work.
that certainly works, did you mark all your variables EditAnywhere

and the struct BlueprintType

[dusk flame]

@supple dome yeah I just did a done of learning about it all. I guess in this case the C++ parent is marked as BlueprintReadOnly, so whenever I try and call MakeStruct (which is the node I was looking for all along!), it doesn't have any fields.

[burnt anvil]

want this tree to execute when isdead becomes true , what should i plug the exec input of the branch into ?

[tiny bay]

hi guys, quick question; so I want to set an actor to patrol on a platform, but if I play the scene, the actor just disappears

would there be a reason why?

I don't think it's moving out of bounds too quickly or anything; I've tried anything from .00 to x100s but they all disappear instantly

this is the code

[rough jay]

is the actor destroying? when it disappears find it in the actors tag then press F to see where it went?

[tiny bay]

no, it doesn't have a destroy function, it should be just running back and forth

i think something is wrong with GetWorldLocation because it is visible on the scene until I add that bit and connect it to setrelativetransform

[rough jay]

whats the world location when it disappears?

[tiny bay]

like immediately on its spot

as soon as I hit play, it just disappears immediately on its original location

[rough jay]

find the object name

then press f

[tiny bay]

while it's running?

[rough jay]

well when it disappears it goes somewhere

[tiny bay]

doesn't focus on anything if I press f

[rough jay]

sus, print out the world location then go there see if its visible

[tiny bay]

oh my god LMAOOOOO

@rough jay ok so it was moving at an exponential speed

I needed to decrease it even further

it moves at like 600 units per second

thank you for your tip to print out the coordinates, that actuallly solved it

[sour urchin]

Water not work, why?
i add WaterMeshActor and WaterBodyOcean to level, but nothing happen

[rough wing]

I have this function which runs on a timer.

I want to set the stance variable if there is no wall to run

Currently it sets stance to Default each timer tick

What would be a better way to set my stances?

[rough jay]

@sour urchin did you build? also i think water needs a landscape dont live off those words

[crystal mural]

Ah guys, it's been a while. Memory is bad!

I have an Actor Class with a Variable, and I want to cast to it from a Character Class to get that variable. What do I put as the object again?

[rough jay]

try get actor of class for object

[crystal mural]

Now I've got the "You don't need to cast" error. Let me give it a bash.

[rough jay]

eh its a note pretty sure theres a easier way for doing this but if you need a way then yeah

[crystal mural]

Cool this works, thanks.

[brittle knoll]

my method of doing something is terrible and very buggy so i need help figuring out a better one

the stars are joints

the higher up star is where projectiles come out to shoot at the player

what i want to do is rotate the bottom star so that the top one is lined up correctly

also the other thing in the pic is just my garbage rendering of what the enemy looks like

i can't simply use find look at rotation because joint 5 isnt rotating, joint 2 is

[tiny bay]

@rough jay it was so dumb; I was using world location (with the original point at 2700), so it was taking that and multiplying it by the velocity. i had to use relative location so it could start at a non 0 lmao

[wintry patrol]

Hello, I am working on a strategy game and I cannot figure out how to do one thing. I have buildings that have "slots" that characters can enter. I do not know how to make characters "enter" the buildings. I need them to remain valid actors while being as close to "non-existent" for the surroundings as possible. I have considered the following:

• Save the location/state of the character and destroy the actor, then when leaving the building spawn it and load its state - the problem is I have UI and other things made so they do not account for character disappearing. I would have to change some things this way. Also "ticking" and it's AI will stop working which is not nice...
• Teleport character to some location outside of the map - this sound both stupid and smart 🙂 This way character would still be "ticking" and present for every other game component.
• Hide the character - it it easy to do visually, but how to hide it from an enemy AI?
  Are there any other solutions that I do not know of? I am leaning towards the second one. Any thoughts guys?

[wind void]

🤔 Maybe a boolean called active? and and checks toward the player first checks whether it's active or not thats how i'd do it :P

-=-=-=-=-
Is there a way I can have a 2d image as a child component of an actor?

I thought of using a plane, but then I'd need to make a new material for every image I'd like it to display.

[wintry patrol]

@wind void Paper Sprite?

[orchid garden]

@wintry patrol - maybe look at how they do it for RTS characters?

[wind void]

I'd need to make a new 2d sprite instead of a material for every image still, I was hoping there was someway once I import the png and have several textures, I can just apply the raw texture.

I'd need to make a new material for every image I'd like it to display.
To be clear, I'm not against making a new material. I just like to optimize and try to shorten everything, to using as few assets/functions/actors/blueprint/etc as possible.

[wintry patrol]

I feel like it is just propagating the problem of "remember to check if its active" to many places in the code - UI has to remember to check it, Enemy AI, Character logic, etc. Ideally I would like to just it "inactive" when entering the building" and "active" when leaving so that every other peace of the game do not see the difference/care.

[wintry patrol]

Who are "They"? 🙂

[wind void]

idk on how your AI looks for your player, but it might be possible to fake your character's location. So your character returns a invalid/premade vector as it's location so the AI thinks the character is someplace it's not.
if ya could do this, I'm imagining the possibility of having fake clones of your character just to confuse the AI XD

[orchid garden]

was just a general statement, seen quite a few tutorials on rts games though on youtube. there is also this on the market
https://marketplace-website-node-launcher-prod.ol.epicgames.com/ue/marketplace/en-US/product/real-time-strategy-toolkit

[wind void]

I just remember, you can make a material accept parameters, so I can have 1 material called justAnImage and you'd pass in a image texture and bam 1 material, and all the textures I need.

[shrewd dust]

Is there a way to create multiple blueprints at once and set them each to have a different static mesh?

[wind void]

Create an actor blueprint, have it accept a variable on spawn, then on the construction script have it add static mesh component depending on that variable.

[shrewd dust]

well to complicate things what if level set designer has placed 2000 meshes in the world as static meshes

[wind void]

🤔 How does this become a problem. except 2000 might cause performance issues

[orchid garden]

you could have a master blueprint (actor) and setup in the construction event for it to set the static mesh based on a varable

[spark steppe]

was the delay node removed? (4.26)

[rough jay]

no lol

[wind void]

delay can only be used in the Graphs not in functions, functions were designed to run instanteously. read on UE4 fourm

[spark steppe]

ahh, gotcha. thank you

[shrewd dust]

i had originally planned on doing it in the utility widget editor but it doesnt like that idea

[wind void]

however you can create a new Custom Event and it acts like a function, all other blueprints can access it, it can accept variables and return variables. and they can use delay, as Custom Events can only be made in Graphs

[ocean frost]

Hey guys!

[spark steppe]

thats some nice workaround 😄

thanks

[ocean frost]

can someone help my?

[orchid garden]

when a player drops a item in mine it creates a new actor from the master actor and sets the dropped mesh to the object:

its all done in the construction script of the master actor

the idea would be the same for what you were wanting, you'd just need a varable holding the static mesh object refrence to pas to Set Static Mesh

[ocean frost]

👍

[spark steppe]

are you sure that events can return data? to me it looks like the delay stuff is run async and the Completed output is a internal callback when that async task is done

so there's no real delay when executing it from a function

[wind void]

🤔 oh maybe I got confused w/ smt else. I coulda sworn I had a return output on a custom event a while ago.

[odd ember]

you are correct, it is run as an async task

[wind void]

But yea it makes sense the events are ran async

[final hound]

Im controlling a ball with my BallController. I want to possess what ever other ball (of same class) it hits. I have come so far to quess its Hit Component Event on the BP_ball, but what nodes to use from there? Can someone give some hints? Im quite new to UE4

[odd ember]

Hit Event: OtherActor > Cast to Ball > Possess

[ocean frost]

Someone make a game like Roll-A-Ball?

[final hound]

And then somehow make use this only happens one time, because when the logicis on the BP, ball1 hits ball2, but ball2 also hits ball1, correct?

[odd ember]

true if it's the same actor class

you can do another check for if it's already possessed

but try it vanilla first and see if it gives you issues

[midnight wedge]

I dont really know what channel to post this in but how do I get rid of these folders?>

[rough jay]

del

[midnight wedge]

Ive migrated everthing out of them so they are just dead weight

these ones refuse to delete

or to be renamed

[wind void]

any errors when trying todo so?

[midnight wedge]

nope

just wont register

[rough jay]

open the folder

then delete?

[midnight wedge]

if I try to rename it a new folder with the nbew name is created

[wind void]

so when you hit delete, nothing happens? and if you right click the folder is the delete option greyed out?

[midnight wedge]

its not greyed out, but it does nothing

I assume it has to do with the name because I am having the same issue with another folder that also has a "Maps" subfolder

Everything in frank's sword and warrior sword have been migrated to imported packs, but the empty folders wont delete due to the empty folders inside

weirdly enough Im able to rename the migrated maps folder

[vital shard]

Can you have multiple different blueprints call one specific Event Dispatcher (so multiple Senders) with only one blueprint (only one Receiver) listening for that event?
The Unreal live training says you can have multiple Receivers but I'm struggling calling the same event from different places. Is that possible?

[midnight wedge]

Also I validated the assets in the folders and it said there wasn't anything

@vital shard Yeah just use a custom event

If needed you can feed multiple lines into one sender

[vital shard]

And if you call the custom event the same name as the event dispatcher you've bound something to in the Receiver it'll call that event? (sorry haven't used dispatchers that much yet)

[midnight wedge]

yeah I think so (I'm not good with the terminology)

I can VC and screenshare if you want

[vital shard]

Oh that would be super helpful

[midnight wedge]

coolio which channel?

wait Im dumb theres general

[vital shard]

Support maybe? Seems empty and appropriate

[midnight wedge]

nvm you cant videostream in general

[neon sorrel]

Im curious if anyone knows, I keep getting a pending kill error whenever trying to cast to my character after respawning it, but I have used is valid nodes to make sure its active. Any reason why it would still be doing that?

[mortal wharf]

I have a was recently rendered here but i have a problem with it, it never does the false, it only does the true. https://gyazo.com/7bf30834c7e78ca9a4f912d63c9b837f Why is this happening?

[mild pecan]

I'm looking for an equalivlent function from Untiy. Quaternion.FromToRotation(transform.up, Vector3.up). Any one have some clues?

Essetially I have a capsule that I want to add torque to so it will stay upright-ish and bobble around

[odd ember]

you might not find it in a single function but I'm pretty sure there's some QuatToRotation nodes you can use

[upper linden]

in a 3rd person shooter, when i enter combat, i wanna change camera position

is it better to modify FollowCamera or CameraBoom ?

[brittle knoll]

how can i find look at rotation but lock it to one axis?

[odd ember]

there is no right anaswer

[brittle knoll]

i just want something to rotate in only one direction toawrds the player

[odd ember]

depends on your workflow and how you want to position your camera

you may find that having another camera will help you

[upper linden]

what about my question

[burnt anvil]

maybe you can right click on the rotation pin, split it and use just the axis you need ?

[brittle knoll]

uh

no i cannot

let me rephrase my problem w/ garbage diagrams

i only want it to rotate like this

but still face the player

[odd ember]

I gave you an answer

also you're not owed an answer

so settle down

[odd ember]

can you give a bit more context? which direction is facing the player?

[brittle knoll]

it spins around on the cylindrical rod

[odd ember]

okay, and when it turns which way is it facing? like if it's facing the player at an angle

I mean it sounds like find look at rotation will do it

[brittle knoll]

no because

[odd ember]

if you pick the correct axis and zero out the others

[strong geyser]

Anyone here have experience using a tick in UMG? Or making a "Set Timer By Event" or "Set Timer by Function Name" work?
Timers don't seem to be doing anything for me, despite them being on loop

[brittle knoll]

ill try it

[odd ember]

yeah because you dont put timers on a loop wtf

sounds like your setup is the issue here

[strong geyser]

There is a tickbox called loop

[odd ember]

fair enough if that's the case

[brittle knoll]

for context:

[odd ember]

yeah look at rotation should handle that fine

but also show your setup just to be sure

because unless you use delta seconds on frame 0 of the game they should work

[brittle knoll]

oh so

yeah it does

i should have clarified this

the problem is how it does it

because i'm lerping

from the original rotation to the new rotation

[odd ember]

show your setup

[brittle knoll]

uhhh...

let me clean it up first

[strong geyser]

Okay, solved already, had time set to 0 lol, assumed with loop on that it would just work like a regular tick

[clear cave]

in blueprints for a multiplayer app, what is the best way to branch logic that I only want to run on client-based GameInstance instances.

I tried GetGameMode->HasAuthority but that seemed to not work.

[odd ember]

you can use set timer by event with the CreateEvent node as an alternative to set timer by function name too

[odd ember]

you're using bone rotation

[brittle knoll]

yep

[odd ember]

I'd be very very careful with taht

[brittle knoll]

why does it matter?

[odd ember]

seeing as bones have 4 different locally interpreted spaces to be in

[brittle knoll]

i'm using world space though

[odd ember]

and even though it says world location I wouldn't trust it to actually give you the correct world location

[brittle knoll]

oh

[odd ember]

as an aside

for something such as this

there is no reason to use bones

[brittle knoll]

point made idk why i did

lol

the rest of the enemy is rigged but ill make this seperate

[odd ember]

just make sure your cannon pivot is well centered on its axle and you should be fine

finally, your lerp was never hooked up

[brittle knoll]

yeah ik

[odd ember]

I would hook it up to a set world rotation node of the static mesh component you're hooking up

with the pivot set correctly

that should be enough

no bones, no bs

[brittle knoll]

okay but that still doesntfix the problem of

during the lerp path

it rotates in multiple directions

[odd ember]

you're using 3 axes

for your rotation

zero out two of them

[brittle knoll]

tried that but it doesnt rotate all the way

[odd ember]

what do you mean "all the way"?

[upper linden]

@odd ember i was cool and relaxed, don't imagine things when people say words

[brittle knoll]

uh

[upper linden]

why some much hate, jeez

[brittle knoll]

like it likes to rotate in two directions

[odd ember]

because you're acting entitled

nobody likes that

[brittle knoll]

so if i zero out one it only does a partial rotation

[odd ember]

can you show a gif or a diagram?

[upper linden]

im not acting entitled, you're imaging things

[odd ember]

"what about my question"

[upper linden]

i asked politely if you had an answer

[odd ember]

is a pretty entitled response to give

I'm not looking to argue

I gave you feedback

[upper linden]

change your behaviour, you're assuming that people are on the negative side

[odd ember]

you can take it or leave it

[upper linden]

whatever kid

[odd ember]

that attitude isn't gonna get you far

[upper linden]

forget about it, it's useless to debate it

[brittle knoll]

can you hop in vc so i can screenshare something? you dont have to talk or anything but it's the easiest way for me to demo

[odd ember]

tbh I don't have the time

[brittle knoll]

fair

[odd ember]

it should be a really easy problem to solve

[brittle knoll]

ive been at it for hours so

i wish it was

but i cant like articulate the problem right so

[odd ember]

yeah that's the main issue with doing this over the internet really

I'm thinking you're complicating it by having one component when it should be two components

as in

the base should be one component

and the cannon itself should be a child of the base

so the cannon will move and rotate with its base

but it will also have it's own up and down rotation

but that's just theorycraft on my side

[brittle knoll]

well

that did it

gonna murder past me for being an idiot using bones for no reason

it works mostly

[odd ember]

so my theory was correct?

[brittle knoll]

yes

however

it still does the weird rotation sometimes

here:

took this in slow mo

it rotates incorrectly there

this is what i want it to do:

[odd ember]

I'll put "being psychic" on my CV then 😅

[brittle knoll]

lol

see here it looks just by rotating the one way

but in the other clip it rotates multiple ways

any suggestions? tried physics constraints but those didn't do anything

[odd ember]

Can you show your new and improved setup

[brittle knoll]

yeah

[odd ember]

Don't use anything physics related if you can avoid it, ever

[brittle knoll]

basically the same thing but without bone garbage

[odd ember]

cut your oldrot variable and just use GetRotation directly in the lerp

completely unnecessary and may be screwing your setup

[brittle knoll]

okay

[odd ember]

also

you're setting world rotation on two objects for one timeline

you should have separate lerps for each object

presumably that's what's screwing you here

the cannon turret itself just needs 1 axis of rotation

the base needs the remaining two

cross that

the base needs just one as well, unless you're putting it anywhere else but the ground

[brittle knoll]

there's only one object?

what?

these are both for the same thing

i just couldnt fit it all in one pic

[odd ember]

I see Pivot and Rotbitbossturret on your SetWorldRotation node

[brittle knoll]

yes i know the turret just needs one axis thats the whole problem

oh

picot

ignore that

it doesnt do anything

[odd ember]

I reckon oldrot is the thing screwing you here

but there may be other issues as well

not showcased

also

[brittle knoll]

got rid of it

[odd ember]

if this is just for the cannon turret

[brittle knoll]

yeah

it is

[odd ember]

zero out two of the axes

[brittle knoll]

which two?

[odd ember]

x/z probably

[brittle knoll]

zero them out where?

before or after the lep

*lerp

[odd ember]

pitch is up/down, yaw is left/right, roll is tumble left/right

before

or it doesn't matter

and the same with whatever you plug into your A parameter of your lerp

[brittle knoll]

tried them all

none worked

y was the closest but

[odd ember]

Your game is positioned on the y axis so that's why. You can see it moving correctly but facing the screen

Add 90 degrees to that rotation

Axis*

[brittle knoll]

add it to the x or z?

okay here:

this happens:

[odd ember]

so just to clean up the clutter

if you click on a rotator pin

or most pins really

right click

you can split it

so you dont need to have an additional "make rotator" node

and no add it directly onto the axis

[odd ember]

as use float + float

okay it seems to work

[brittle knoll]

no

look what happens when you get behind it

[odd ember]

yeah

but you have to rotate the BASE

to get that

that's what I said initially

the cannon turret itself is correctly rotating

if you want to rotate it flawlessly over the top you'll have to use quaternions most likely, which will complicate your setup

or do a clever hack to turn your cannon around when it is pointing upwards

[brittle knoll]

thats what i want though

i don't want it to magically spin around up there

[odd ember]

it's not magical

it's just how it works in real life

mario faces the front too when he turns from left to right

[brittle knoll]

i mean yeah i don't expect him to walk on his hands backwards

but this should be like

[odd ember]

if you have your base rotating

that is the simplest

otherwise like I said you're dealing with some hard math

[brittle knoll]

it should be like this when the player is behind

[odd ember]

yeah

so rotate the base

[brittle knoll]

no this is without base rotation

[odd ember]

well I'm telling you that base rotation is the simplest

[brittle knoll]

fair

guess ill start looking into quaternions then

[odd ember]

rotation is extremely fickle when it gets to the extremes

hence why you need to use quaternions

otherwise you end up with an axis collapse, e.g. gimbal lock

which is basically the same as standing at the north pole - any way you go is south

[brittle knoll]

okay kind of confused but following so far

[odd ember]

quarternions basically use black magic to skirt these restrictions by what can best be described as interdimensional travel

I'm not big on using quarternions, I'd rather fix it in a different way than resort to using them unless I absolutely have to

there's nothing wrong with them per se, they just require you to be very math savvy to get right

both for the initial setup and for the potential debugging that will follow

[brittle knoll]

HOLY F I GOT IT

STUPID DUMB BRUTE FORCE WAY LETS GO

it doesnt make sense entirely but like

it works!

@odd ember thank you for all the help!

[odd ember]

Yeah that's another way to do it

Good work

[weak apex]

How can i target my "arm_mesh" in "play anim montage"?

cuzz when i try i get this

is it possible?

[odd ember]

probably

but I'd ask in #animation

[weak apex]

i thought this was a more suitable place since its problem with nodes

rather than animation

[odd ember]

I'd say it's an animation problem seeing as you need to know what to supply for the animation

in either case I can't help you, I can only point you to people who might be able to

[weak apex]

alrighty

ill post my problem there

thanks

[orchid garden]

i've made a data table for player levels vs. amount of xp they need for the next level, does anyone know how i can determine how many level ups a player would get if say if they had a total of 1190 xp but were currently level 6 (120 xp) ?

[odd ember]

get an experience point manager to calculate that by referencing the values in the datatable

you know how much experience you need for each level so you need to do a searching algorithm that will find the correct level for you. alternatively perhaps once you load your data table into an array, you can use UE4's built in array functionality to find something like closest upper bound

[tight schooner]

@rough jay It's the delay. Every time your "Kill" custom event is called, it updates the data output.

rip

I guess you figured it out

[rough jay]

thx tho same thinfg i didye

[tight schooner]

I was going to suggest "Set Lifespan" as an alternative to delay-destroy

[orchid garden]

so i looked a a few leveling tutorials, none of them seem to do it that way just per level, checks to see if they have enough xp to go to the next level after leveling up the last level.

guess thats easier then jumping say 4 levels at once, give the player their stuff for the level, then check for next level after they've leveled up and give them the stuff for the next. basically a loop... till they can't level up again.

[wind void]

couldn't think of a better channel for this question
Is there a way to make the particles in Particle System to spawn all at once?
then all fade out exactly the same?

[rough jay]

well first they cannot loop i suppose then when you want to just spawn the emitter maybe

[orchid garden]

@wind void maybe in #graphics ?

[wind void]

I'll continue in there

[rough jay]

is this unnecessary?(the valid blocks)

[tight schooner]

@wind void Spawn as a burst (rather than continuous) and set the lifespan of the particles to a fixed value. The workflow for doing that is slightly different between Cascade ( #visual-fx ) and #niagara

@rough jay Checking if array index 0 is valid is (AFAIK) checking if there's anything in the array at all. ("Array Length > 0" would do the same thing.) Logically speaking, your script is checking repeatedly if there's anything in the array

I would suspect you only need to check it once, but I don't have a deep understanding of your game so only you can answer whether you need to repeatedly check if index 0 is valid.

[rough jay]

thx

[wind void]

So I had a Begin Overlap event, but it appeared to be running twice, I assumed it was maybe due to a 2nd mesh in my player triggering the overlap again. So I added End Overlap event to make sure begin overlap won't be ran again until end overlap was called.

Yet somehow both events are being called twice, in this order: begin, end, then (function in begin) then begin, (function in begin) then end

[odd ember]

I do not recommend this

it's like putting a band aid on a broken bone

your issue is likely in how the physics responds to different channels, so I would debug it to find out which component is causing the issue and exclude that component

[wind void]

it didn't even work so I was asking how I might go about this.

[neon sorrel]

Does anyone know why im getting a pending kill error when respawning my character?

I put is valid nodes but doesnt seem to fix it

[odd ember]

probably because it's targeting the old character being killed off instead of the new cahracter spawning

but idk

I'd need to see logic

[neon sorrel]

Hmmm, Yeah not sure exactly how to fix that. I just simple set a variable for my character as soon as it spawns, and referance that throughout the player controller.

Aha

Wait isnt the player controller still with the person when they respawn?

Its just the character that gets reset

[odd ember]

the player controller never dies, correct

[neon sorrel]

That may be the issue then

Is there any way I can respawn the player controller somehow then?

[odd ember]

I do not recommend killing off the controller

[neon sorrel]

Hmm

[odd ember]

you'll have bigger issues

if you do that

[orchid garden]

when you respawn the character set a new reference in the player controller for the pawn?

[odd ember]

but anyway it would be easier to show us the logic

and we can take it from there

[neon sorrel]

Give me a moment and ill get some screenshots for that

[orchid garden]

im assuming your using a variable to store the player pawn in the controller, so i'd think you'd just need to destroy the first pawn, make the new one, and replace the reference of the old one with the new one.

[odd ember]

in all likelihood your spawning is custom, and this is definitely one of those places where I recommend using the built in functionality in the GameMode to set up your spawning

[scenic scroll]

very noob question here- if i wanted to make an object (say a forcefield) disappear so it can't be seen and you can walk through it but not delete it so it can be later activated in the same place, what would be the best way to do it?

[odd ember]

toggle off collision and visibility

[neon sorrel]

^

Heres the initial setting of the character ref in the player controller though

[wind void]

So in my player I made all components but the root have: no collision & generate overlap events: false
And in my Actor that checks for spikes, I use only my Box Collision's Overlap event. Yet somehow I'm still getting 2 events.

[odd ember]

yeah that's definitely down to you using GetControlledPawn

also generally avoid using the IsValid macro

[neon sorrel]

Thats what I was thinking may cause it. Is there any other one I can referance besides the pawn? 🤔

[odd ember]

use the bool function instead and set it up with a branch

there are some BP general issues with using macros in places and you don't want your IsValid checks to die because of that

[wind void]

when creating the new pawn, have the player controller posses it immediatly?

[odd ember]

GameMode has an override function called something like SpawnDefaultPawnFor

I recommend you use that to spawn your character

[neon sorrel]

Hmm. I see a option to spawn default controller.

[odd ember]

which function?

[neon sorrel]

Nevermind, thats a node

I dont see any overrides for spawning though

[odd ember]

spawning what?

[orchid garden]

@odd ember you mean these?

[odd ember]

no. those are nodes. override functions are functions built into a class

and they're just cast nodes too. they don't actually do anything for spawning in this case

[neon sorrel]

I added a isvalid node to the function and got it to work in the player controller, just now referencing it in the hud doesnt work

[odd ember]

@neon sorrel I strongly urge to let your GameMode handle your spawning

[neon sorrel]

The gamemode does, its just that when it respawns it seems the player controller doesnt get the new character and set the referance properly

[odd ember]

show me your spawn functionality then

[orchid garden]

@neon sorrel this might help:

types is a list of character class refrences, and current type is just a int to the type in the types list.

that basically lets you cycle through a set of pawns destroying the previous one and setting you in control of the new one.

[odd ember]

you shouldn't really be doing any of that manually

[orchid garden]

its for pawn testing

[odd ember]

ideally you set the next character to a variable in the player controller as you are spawning it, and that should be enough

no need to overcomplicate

[orchid garden]

but it gives him the basics of killing off one pawn and taking control of the new one.

[odd ember]

yeah you really don't need that

let the garbage collection do its job instead of trying to minmax it from a point where you don't have control over it

[neon sorrel]

Thats basically what im doing, just spawning a new actor, destroying the previous pawn if it exists, and possesing the new one.

[odd ember]

is this part of the SpawnDefaultPawnFor function?

if it is, all you need to do there is reference your player controller and set your new player character as a variable

then use that variable exclusively

this will ensure that you will always have the correct pawn called

[orchid garden]

i see one major difference, your setting the owner on the spawn actor, as the one i showed you doesn't, it just sets the player controller to the target when possessing. your also destroying the actor before you possess the new one.

i know the one i showed you works properly, i've been using it for pawn testing for awhile.

[neon sorrel]

Hmm yeah I see that a bit, let me take a look and test somet things

[orchid garden]

gl 🙂 hope it helps

[neon sorrel]

And no its not @odd ember its different. And apologies for the late replies

I am looking at that override now though

[odd ember]

my question is then: why is it not. that function will solve many of the possession issues you're facing

[wind void]

How would I go about a vignette? would that be like a widget? Or is it possible todo that with a component?

[odd ember]

if you mean like a camera vignette you could do that through post processing filters on a camera and just have a material

but it depends on how much functionality you need in it

is it a static effect that you just want to turn on off? do you need it to do more than that?

[wind void]

I'd like a vision blocker, but it can change size depending on level. I assumed a vigenette would work.

[odd ember]

vision blocker is very vague

[wind void]

🤔 All but the center of the screen is black, the radius of the center changes showing more or less of the screen.

[odd ember]

is that all?

like you don't need anything more than that

[wind void]

I'd like some way it could have a translucent center fades to the blackness

[earnest tangle]

Sounds like a post process material would do it fairly easily

[odd ember]

yeah all of that can be a post processing material then

[wind void]

I've never used that, Imma google it.

[odd ember]

you can scale the screen effect with a material instance too

ask in #graphics

and I literally mentioned postprocess effect on the camera before

[wind void]

Yea when you said that, I went to my camera component and was trying to find what you were talking about.

[odd ember]

it's in the detail panel under post process effects

there should be one called materials or some such that will show you an array

add an entry then pick out a material

done

but!

if you want it to be dynamic

you'll have to make a dynamic material instance and work with it dynamically

e.g. with whatever triggers you need

[neon sorrel]

@orchid garden Tried doing stuff like yours, Doesnt seem to work the best. Still have pending kill errors now :/

You said set the player controller to the target?

[shrewd palm]

Hi all is this the right place to talk about UMG related stuff?

[neon sorrel]

I would assume so

[shrewd palm]

just wondering how does one keep a value in a slider, using it for time of day, but each time I press a button to bring up the slider it defaults back to 0 rather then the time of day value

[neon sorrel]

Try using a savegame? @shrewd palm

Or just set a variable in a instance

And cast to that to check every time

Then set the slider

[shrewd dust]

Any idea how to set the default static mesh of multiple blueprints from an editor utility widget as its created in the widget? I have about 250 meshes that I'm generating blueprints for and then need to set the default mesh to each of the static meshes.

[crisp thunder]

Is there a way to convert a mech into a height map?

[scenic scroll]

what's the difference between a skinned mesh and a skeletal mesh?

and would this code work (which wants a skinned mesh component as target) if the target was a skeletal mesh?

[quasi glen]

I'm currently working on the HUD so it will display how many coins are collected. The number the script is binded to isn't showing, so something is kinda screwy. Here's what I have so far for it.
https://cdn.discordapp.com/attachments/689574327150182456/785731968389087232/unknown.png
This is what its referencing in the Ball pawn BP
https://cdn.discordapp.com/attachments/689574327150182456/785732077936312333/unknown.png
I have initialized the HUD and here's what is happening when I play the game
https://cdn.discordapp.com/attachments/689574327150182456/785732434066931762/unknown.png

[elfin inlet]

you can use increment node for adding coins in your ball BP instead of using + 1

[stuck hedge]

Spawn emitter attached doesn't seem to be working. I've got it set to snap to target, and I've picked a component on the actor, however if the actor is in motion when I spawn the emitter attached, it doesn't seem to attach. It pops and the actor keeps moving.

[elfin inlet]

also I wouldn't cast in the bind function, it runs on tick (20 ticks per second iirc)
Move your get player pawn and cast to ball into event construct, and promote the ball to a reference

[elfin inlet]

then in the bind function, get your ball reference, pull the coin variable and bind that

@quasi glen

and check if your coin text is set to "Is Variable"

in the designer

[scenic scroll]

i'm having a problem: when i change the pawn's skeletal mesh VIA script in-game the body goes to the default pose and no animations play as if it had no skeleton

this is my code

sorry if its a noob question but i have no idea how to fix it

[elfin inlet]

@quasi glen

[stuck hedge]

You can see what happens if this is fired off while the unit is at rest, perfectly centered, but if you fire it off when the unit is moving it initially spawns in the middle of the screen, but moves down and out of view as the unit moves forward a bit after exploding. Result is, the emitter is not staying attached to the unit.

[elfin inlet]

@stuck hedge if im not wrong, you need to have a socket in the component

attach point name would be the socket name

[stuck hedge]

It won't attach without a socket at all? I thought it would just attach to the supplied component.

and then a point could be used to fine tune the location.

[elfin inlet]

are you attaching to a skeletal mesh

[stuck hedge]

No, it's a collision sphere.

[elfin inlet]

interesting

[stuck hedge]

but I can try a skeletal mesh

[elfin inlet]

it should work

the way you did it

I'm going to switch it to the skeletal mesh body and add a socket and see what happens

Same thing

changed to skeletal mesh added socket, put socket name, it doesn't attach

[scenic scroll]

:c

[elfin inlet]

you need to do some more logic when changing skeletal meshes

[scenic scroll]

could you explain / link to a tutorial if that's ok?

[stuck hedge]

I did that awhile back let me see if I can remember.. there's a reset box in there you need to tick somewhere, and I believe you should set the anim blueprint again

[scenic scroll]

reinit pose?

[stuck hedge]

Yes you need to reinit and if you're changing the actual skeleton you need to tell it what anim blueprint it is using

[quasi glen]

So I just checked that off and I'm still getting nothing.

[scenic scroll]

not changing the skeleton, just the mesh

[elfin inlet]

it needs to be enabled

[quasi glen]

I just enabled it, still nothing

[scenic scroll]

also thanks a lot i'll try that

[stuck hedge]

It wasn't this project I did it on. I did it on a project like...a year ago..hmmm.. let me see if I can find it

[scenic scroll]

thanks a lot :)

[elfin inlet]

you should move your cast off the bind, thats running on tick for no reason

get the ball reference in event construct in the widget and promote it to something like BallRef

and replace your cast in the binding with BallRef getter

also you can use the debugger to see where it is failing

[tiny bay]

I don't think that's the problem here, i did the same project as him and mine worked fine without all that

[stuck hedge]

Project hasn't been opened in awhile it's going to take a minute to get open

[elfin inlet]

just an advice 🙂

[tiny bay]

yeah that's fair

just wanted to lyk

[scenic scroll]

that's fine, also i tested with init checked and same error still ocurs so it wasnt that (or at least not just that)

[stuck hedge]

I even tried attaching to the capsule component, no luck, still stays in space while the actor (made invisible) moves forward slightly

[chrome quiver]

This structure is getting quite long, there anyway to have a dropdown that maximizes/minimizes for it like a Break Hit Result for example?

[elfin inlet]

tell me if you find out 😄

[chrome quiver]

doin my best to, haha

[elfin inlet]

maybe collapsing node might only show the used pins

[chrome quiver]

had to split the pins to show them in the first place, if one's being used I can't

[stuck hedge]

Keep in mind this was for a multiplayer VR situation, but here is what I did for changing the skeletal mesh and making it work: Set Actor tick enabled-> False , set skeletal mesh, set anim instance, set it replicated, set actor tick enabled->true

[scenic scroll]

what is "set actor tick"?

[elfin inlet]

no i mean right click>collapse nodes

[stuck hedge]

"set actor tick enabled"

@scenic scroll

[scenic scroll]

i know how to use it- i meant what it does

[stuck hedge]

that controls the event tick.

[elfin inlet]

it toggles tick

[stuck hedge]

if it's set to false the actor isn't ticking.

[chrome quiver]

Ah, I mean that works, but still doesn't look so good

[stuck hedge]

changing the skeletal mesh while ticking is dangerous and can often cause a crash

[elfin inlet]

gosh this is ugly LOL

[stuck hedge]

I believe you can right click a struct and tell it to hide unused nodes

[chrome quiver]

I want that dropdown bb, Imma dig hard for it

[scenic scroll]

what function does it serve in the script? does it not lose its skeleton if it stops ticking?

[elfin inlet]

then you will need to compile from source. good luck

[stuck hedge]

It serves the function of not crashing the game. The anim instance works on tick. So if you're changing the skeletal mesh and anim instance while it's ticking it can cause an exception

[scenic scroll]

aha i see

i'll test it out! thanks!

[stuck hedge]

@chrome quiver

[vocal elm]

how can you cast to a non-player character class?

[stuck hedge]

The same way you cast to a player character class, get a reference and cast to it

[vocal elm]

what would you put in the object? since the way to do that is to get that reference from the player controller, which is not controlling that character

[stuck hedge]

That depends on the context of what you're doing?

[chrome quiver]

Ain't there, wish it were tho, lol

[stuck hedge]

is the player looking at the object? Touching the object?

[stuck hedge]

Look at the screenshot. Do you have a break node in the graph like I do?

[vocal elm]

its a character never controlled by the player ( i realize now i should have used pawn, and added character movement comp for my needs) I have a progress bar UI widget inside the blueprint, i'm trying to cast the value to the progress bar

[elfin inlet]

its under the break struct nodde

[elfin inlet]

you can use get owner or get parent actor

[stuck hedge]

Okay, but what is the relationship to the scene? Is there only one of this actor in the scene?

If you need a reference to another actor in the scene then you need to resolve the relationship. Touching, looking at it, simply existing, etc.

[chrome quiver]

🤯

[stuck hedge]

Then you can use either an overlap, line trace, or "get all actors of class" to try and find it.

[stuck hedge]

So click that and then look at the details panel on the side

[vocal elm]

that is for actor class, not character class

[elfin inlet]

character is child of actor

[elfin inlet]

inheritance goes like this:

Actor
Pawn
Character

[vocal elm]

an actor is not a character

[elfin inlet]

where is this logic

[vocal elm]

widget casting to blueprint

[chrome quiver]

It brings a tear to my eye 🙏 Thanks for the help @elfin inlet @stuck hedge

[elfin inlet]

in which class are you calling get parent actor

[stuck hedge]

You're not providing us enough context and information here to help you

[vocal elm]

get all actors of class should work for me, thank you I forgot about this

[stuck hedge]

If the widget is actually attached the actor (say in a VR scenario) on begin play you can have the actor set a "parent" variable on the widget.

[vocal elm]

okay imagine having a mannequin character you never control

this character has a widget component to have a health bar over his head

i'm trying to set that health bar, by casting from the health bar, to the mannequin character

[stuck hedge]

ahha

yes.

[vocal elm]

cannot do that due to not having a reference in the player controller

[elfin inlet]

....

you don't understand the logic here

[stuck hedge]

So in that case, attach the widget to the actor in game and on "begin play" get that widget and set a "parent" variable on it.

He's basically got health bar widgets attached to NPCs.

[elfin inlet]

yeah and that has nothing to do with playercontroller

[stuck hedge]

On your widget create a "parent" variable of the same class as your NPC mannequin.

then on begin play cast to the widget from the mannequin and set that variable as self.

[elfin inlet]

he needs to get the user widget object from the widget component and cast it to whatever widget he is using as the health bar

then set the reference to the character in the widget

[vocal elm]

I don't think you guys are understanding

you cannot set reference in the widget

[stuck hedge]

We understand.

is the widget attached to the NPC Mannequin?

[vocal elm]

I cannot cast to character from widget

[elfin inlet]

you do the opposite

[vocal elm]

yes its a component of

[stuck hedge]

You don't need to cast to the character, you cast to the widget.

Let me open my VR project back up, I did this 100 times in that project.

[vocal elm]

after you said that I realized I need to do the opposite, yes thank you lol I wasn't realizing

[stuck hedge]

for everything.

because everything is a 3D widget.

[vocal elm]

but it still doesn't look like you can cast to a character class that is not ever being used by a player

[stuck hedge]

It's not a character class, as you said, just an actor

[vocal elm]

then why doesn't get owner work?

[scenic scroll]

@stuck hedge sorry to bother you again but- I have no idea what i should set the anim instance class to (modding, not making a game from scratch) what is that? any clues where i can find it?

[vocal elm]

(not arguing, trying to understand)

[stuck hedge]

You'd set it to whatever the anim class is for that skeletal mesh, I couldn't tell you what it is

@vocal elm Do it like this. THis is the actor, the same as your NPC actor

[elfin inlet]

@vocal elm you need to do this in the characterBP

[stuck hedge]

this is the variable on the widget itself

[scenic scroll]

the prefix for anim instances would usually be "ABP_" right?

[vocal elm]

yeah I was doing it backwards, in the first place I should have made the NPC a pawn with a character movement component. but actually you are both right I was trying to do it in the wrong order. From widget to character, I need to do character to widget.

thank you both, much appreciated cheers 🍻

[stuck hedge]

it might be if they've named it like that

[elfin inlet]

it has nothing to do with your class being a pawn or a character

[stuck hedge]

I think what he's talking about is using "get player controller" to just get the player controller and then get its pawn from anywhere.

You can pretty much always get a reference to the player controller from anywhere since it's a universal thing

[scenic scroll]

"animation instance class" is an animation blueprint right-? i just dont know what it is at all sorry if its a dumb question

[stuck hedge]

Yes that's correct

[elfin inlet]

you just need to use the widget component reference (which automatically gets created when you add one)
get which widget it is showing (because the widget component is just a "container" for a widget)
cast the widget to whatever you set it to be
and now you can access data in there @vocal elm

[stuck hedge]

what game are you modding?

[elfin inlet]

thats as good as i can explain this

[scenic scroll]

i think i got it then it should definitely be ABP_Character

[scenic scroll]

Brick Rigs

can't ask for help in the BR community itself cause i'm the first one ever doing something like this afaik (very small modding community)

[stuck hedge]

Ah, yeah.. the modding is all going to depend on what they've made available to you

[scenic scroll]

nothing since no official mod support
it does look like it must be ABP_Character tho since its the only .uasset looking like it'd fit the profile, so i just have to reference it and hopefully it should work

[stuck hedge]

if the character doesn't share the same skeleton as that abp then it won't work.

[neon sorrel]

Does anyone know why I get this pending kill error? When my character respawns everything works except it wont show parts of the hud because it cant get the actor it trys to referance. Though I used print strings and it does get the proper actor. It just seems to never actually die.

I used a event destroyed node as well to destroy the actor but nothing still

[scenic scroll]

it didnt work, still no animations at all... but it does share the same skeleton

[stuck hedge]

there might be another ABP, if it shares the same skeleton when you open the original character blueprint the anim bp should be listed there

[scenic scroll]

ok so i saw one different bone

but there's an issue

this is the vanilla character

this is mine

i get this when importing

why can the vanilla character have a duplicate bone but not mine? :/

i think i might have found the problem

[stuck hedge]

If you're importing a character, it doesn't have the same skeleton.

Even if it is "the same"

you need to actually go to the mesh and assign it the same skeleton

[scenic scroll]

@stuck hedge i found the problem that was happening

exporting the original character from ue4 into 3ds max caused a new root bone to appear (with the name of the file)

so it wasnt really my fault xD

now it works... but it's too big, i have no idea why

i wonder what exactly i should be downsizing because when putting the sk_raintrooper (the character) into the world by itself (not by replacing the player's SKMesh) it's the right size

[spring hare]

@scenic scroll The player mesh could be the problem

[scenic scroll]

which... player mesh? the one i'm replacing?

[spring hare]

The one that you are assigning the storm trooper to

[scenic scroll]

the stormtrooper is replacing bob's (left) skeletal mesh

as you can see they're the same size (i didnt downsize those stormtroopers on the right, they're the SK as it appears when plopped down into the world)

[spring hare]

Is bob's size increased?

[scenic scroll]

unsure what you mean

i can normally go around as bob without any problems or size-anomalies

when i activate the script to change into a stormtrooper

is when he becomes bigg

[spring hare]

Then you might have to shrink the mesh size in the blueprint

[scenic scroll]

how would i do that? (i'm a bit of a noob) also i'm confused because like i said the mesh is the same size as bob when put into the world without script?

[spring hare]

This mesh part

[scenic scroll]

question

[spring hare]

Yes?

[scenic scroll]

ok i found the problem nvmmmm

i think i did at least

[spring hare]

Thats good

[scenic scroll]

the

problem now being i have no idea why its happening

so the skeleton is offset in UE4

yet in max its perfectly fine?

[spring hare]

Skeletons isnt my strongest part but moving the root should fix it

[scenic scroll]

like scaling it?

that just scales the model with it

[spring hare]

Nah just moving it to 0,0,0

[scenic scroll]

it is

[spring hare]

I mean in UE4

[scenic scroll]

i'm unsure how to do that- also an update, it works fine with the original character, just not with mine for some reason

[spring hare]

When the character is place in the world is there a offset?

[scenic scroll]

how would i check that? also would that matter if it doesn't work in the preview either? (sorry if i'm a bit lost)

[spring hare]

Your problem looks like this correct?

[scenic scroll]

what exactly do you mean?

with how the problem looks like?

[spring hare]

Your character is offset to the root?

[scenic scroll]

also thank you for your patience lol

[spring hare]

Its fine

[scenic scroll]

here's my character and its root

[spring hare]

Then its fine?

[scenic scroll]

which seems to be the same as the default character

however the problem is

look at this

default character upper arm

[neon sorrel]

Anyone know why this cast is failing? The parent of mps master is character. So I thought that was the correct way to cast... 🤔

[scenic scroll]

mine

its like if the skeleton was squished down for some reason

even tho it uses the same skeleton as the other character and they're the same size

[spring hare]

Yeah the skeleton seems to be smaller then the model

[scenic scroll]

but they're both the same size

and use the same skeleton

this is weird T-T

[spring hare]

@scenic scroll Yeah try checking your modeling software

@neon sorrel Is MPS the player?

[scenic scroll]

it works fine in the modelling software (ignore the bad rigging

also if you're wondering

if i delete the other skeleton and import the skeleton straight from my software

the problem persists

the skeletons are identical

[olive sedge]

I have a question on collision: my collision component should be the root component, yes?

[spring hare]

@scenic scroll Im not sure if 3d max has it but blender has a opetion to apply tranforms does 3d max have that option?

@olive sedge Yes

[scenic scroll]

reset transforms, but it's the same supposedly, should i use it on the mesh?

[spring hare]

@scenic scroll You can try but i dont think it would help

[scenic scroll]

well- idk what else to do

[spring hare]

@scenic scroll If you want to can dm the file and i can try

[scenic scroll]

thanks :o

[spring hare]

No problem

@scenic scroll This what you looking for?

[olive sedge]

@spring hare I've got a capsule collision as my root. I can't rotate, what can I do?

[spring hare]

@olive sedge The root components cant be altered. If you want to change the capsule make a scene as the root

[olive sedge]

but then collision doesn't work

[scenic scroll]

how? O-O

[spring hare]

@scenic scroll I put it in blender to apply the transforms

@olive sedge You wont have to worry about that if capsule has collision on

[olive sedge]

ok, I'll try

[spring hare]

@olive sedge What is your problem?

[scenic scroll]

ah yes, 3ds max, the 2k program that constantly gets outmatched by the free one

[spring hare]

Haha that does happen sometimes

[scenic scroll]

i really gotta move to blender i literally hate autodesk but i just need to get around to relearning everything and you know- lazy

[spring hare]

@scenic scroll Haha yeah i sent you the file let me know if you have any problems with it

[scenic scroll]

thanks a lot ^^

[olive sedge]

@spring hare i have a dart basically that I want to shoot from a gun. the collision capsule is upright so the collision is off

I've tried everything to rotate it but nothing works. If I make something else the root, the collision doesn't work anymore, if I rotate it in the construction script, it keeps rotating

also, if I make a scene the root, the projectile movement doesn't apply anymore

[spring hare]

Ah okay then you want the mesh as the root and the collision a child of the mesh

[olive sedge]

then the mesh is being forced by projectilemovement but not the collision

[spring hare]

The mesh will be moved by the ProjectileMovement and the collision will follow if its attached to the mesh

[olive sedge]

unfortunately it doesn't

give me a second, I'll create a new capsule, see if I did something wrong

ah yes, this one follows

I still can't rotate the mesh however

[spring hare]

The mesh should face the way you want it to go (Basically import it on the x line)

[olive sedge]

what do you mean by import it on the x line?

honest here: I got this weapon pack from the marketplace

and there's a nerf dart in it that I want to use

and it sits upright like a bullet you'd set on the table

I made a different staticmesh the root now and attached the actual mesh and capsule to it

gonna try if I can get that to work

[neon sorrel]

Anyone able to help me with a weird bug by any chance

[spring hare]

@neon sorrel Whats up?

[neon sorrel]

For some odd reason when I respawn my character I keep getting pending kill errors
