blueprint

[sharp ferry]

well im talking too much, thanks anyway

[silent plaza]

hey guys, I think I'm starting to go a little crazy haha 😆 **I can't set an HDPI resolution (Retina, I'm on Mac) that works in the packaged project. ** 🖥️

It works fine in Unreal's Play in Editor, but not in the packaged game.
👉 I've tried all the methods I've found on the forums and youtube (putting code in DefaultGameUserSettings, using the “Set Resolution” nodes) but either it doesn't work, or it crashes the project on launch in the editor....

How do you get the resolution of the packaged game to adapt to the player's screen (Retina or normal)?

This kind of thing is super simple on other engines, but super frustrating on Unreal....

[maiden wadi]

What do you mean by adapt to the player's screen here?

Generally speaking, you shouldn't use SetResolution calls in PIE. It functions differently as an editor window than as a standalone window. Always test your resolution stuff in packaged or at least Standalone mode.

But GameUserSettings should have most of what you need to deal with setting the windowed mode as well as the resolution setting.

[silent plaza]

I struggle to make it compatible with my retina display (high DPI)... i tried everything but i can't make the packaged project displayed correctly, it is pixelated... which is not the case in the project editor

[maiden wadi]

What is pixelated? 3D or UI? Or Both?

[silent plaza]

both

• I enabled NSHighResolutionCapable and confirmed it’s present in the final Info.plist inside the .app.
• I tried setting r.ScreenPercentage and setres via console and Blueprints — no effect.
• I added proper resolution and screen percentage settings to DefaultGame.ini and DefaultEngine.ini.
• I launched the app from Terminal with --args -EnableHighDPI.
• I deleted Saved, Intermediate, and DerivedDataCache to repackage cleanly.
• I tested bEnableHighDPIAwareness=True in DefaultEngine.ini under MacTargetSettings.
• The .app runs fine, but it’s still blurry — not true Retina.

[EDIT - nevermind, I fixed it after long battle] Hey guys. I have an issue with a simple feature. I'm trying to create a coin that falls down to the ground and after hitting it, disables movement/physics. It aslo should be pickable by player character. My setup is two colliders. One that detects hit with the ground and a 2nd one much larger that detects collision with player character. I've made two extra collision presets called "items" and "floor". Now for some reason i don't get any results on contact (im trying to print name of an actor that is hit) with the floor nor player. I would appreciate any help 🙂

[hasty merlin]

how would one go about world items being able to be picked up and added to an inventory? would you create a centralized actor that has all the requirements and then add that to each actor item? or would you set up a class or something and then each individual item references the class?

[faint pasture]

simplest approach is to subclass an ItemBaseClass which all items are subclasses of

[hasty merlin]

to create this it would be Blueprints -> Class?

[faint pasture]

You'd basically want a base class for your items, and every individual item type would be a subclass of it

yes you'd want to make BaseItem be a subclass of Actor

[uneven crest]

Whats the best way to do this menu system. I know how to customize the gun and all that. I have the logic. I just dont know how to get the gun to show up like that. Its part of the widget but still changes

[hasty merlin]

are you by chance able to give me reference images? i have always struggled with understanding classes and i dont know if im following compeltely

[steel shadow]

Wdym get the gun to show up?

Store it as a variable in your controller

[uneven crest]

No i know that but

[uneven crest]

i know how to spawn the gun in and everything. idk how to describe it. I have a widget that covers the full screen. I dont know if there is any way to spawn the weapon into the widget almost, so that it keeps the same background as the widget

thats just a drawup of what i want

[steel shadow]

Could make the widget 3d?

And have the camera face it

Attach to camera

And attach gun to camera

[hasty merlin]

i understand classes now. now i just need to plan out inventory in an actor component and try to understand the importance of a blueprint interface

[faint pasture]

One thing at a time champ

[hasty merlin]

question out of the blue, is it possible to have widget be attached to a face of a 3d model? im thinking it would be cool to see a book open up and on one page of the open book you see the inventory UI but as the book open and moves around the widget remains firmly planted on that one page of the model

[faint pasture]

Yes, the widget would be rendered to a render target which gets used in the material of the thing

might need C++ for it though

[hasty merlin]

that would be so cool so i think when the time comes ill be learning C++ again lol

[faint pasture]

Could probably do something hacky with WidgetComponent by using its material or something

wait a second I've done it, sec

[hasty merlin]

sure 🙂

[faint pasture]

yeah exactly that

yeet the render target out of the widget component and use it in some other material

thats a nice hacky BP way to do it

[hasty merlin]

thats sick. and you can just use layered textures right? like set it to be texture #2 and apply it to just overlap or overlay?

[ruby venture]

is there a better way to check what type a data table is? this feels really wrong

id assume i should be using an actual == object node, but i dont know how to reference the type im looking for

[surreal peak]

I would first ask why you are doing this in the first place.

[hasty merlin]

any ideas on how to code in blueprints:

If NewItem: Name matches item in {Array}, check quantity.
If Quantity == maxStackSize, continue on
If Quantity != maxStackSize, add to until quantity == maxStackSize and subtract from quantity of NewItem then add to array
Else If NewItem: Name doesnt match item in {Array}, add to array

[surreal peak]

Also I'm unsure if GetObjectName is even guaranteed to be the same across all compiled targets.

[surreal peak]

I mean, you basically do what you wrote.

Like, what stops from just coding that in Blueprints?

[hasty merlin]

the checking of name matching and continuing in the array

[surreal peak]

It's like asking "can someone tell me how to pick up a hammer, then a nail, then hold the nail in front of a wall, then hit it with the hammer until it's in the wall."

Right. There are equal operators for names

[hasty merlin]

i guess a for each loop with break would work

[surreal peak]

Yop

In Blueprints you won't have a lot of choice

In C++ this becomes a lot more straightforward

[hasty merlin]

dope ty for helping me figure this out

[surreal peak]

If you have specific trouble feel free to post screenshots

But atm I would suggest to get started

[hasty merlin]

yea i liked C++ when i was coding in it in highschool but now i want to learn blueprints cause its more fun to use then to stare at text all day. colour == fun

[surreal peak]

Sure, just make sure to pick the right language for the job. They aren't exclusive and some things really suck in Blueprints

[ruby venture]

yea thats why i dont wana use this solution, but anyway my game uses data tables for loading gameplay segments, and depending on the struct type, itll use a different type of gameplay segment. i could just add an enum along with the DT to determine what type of segment i want, but itd be easier if i could just rely on the DT struct type instead

[surreal peak]

If you are 100% sure you won't be using a struct twice, then you could check if you can grab the class itself.

But honestly, whenever you have a growing Switch node that could potentially get bigger and bigger, you have a faulty setup to begin with

Gameplay segments could be created as DataAssets. They can hold all relevant data, including your DataTable. The DataAssets can be referenced via the AssetManager and conveniently queried and loaded by it too via a combination of Type:ID. I think the primary data asset that is exposed to blueprints uses the name of BP class for the ID. You can also hook that up to a GameplayTag but that requires c++.

You can then map the DataAsset to the Gameplay sections directly or via the Type:ID format.

And grab the DataTable and other information from it when needed.

[ruby venture]

fair enough, ill look into it 👍

[hasty merlin]

if i wanted to set a quantity from the NewItem when adding to my inventory, how would i do that? im imagining the item i picked up has quantity 27 but the max stack size is 5. I need to add to player inventory with quantity of 5 instead of 27 and then take the 5 away from quantity of NewItem and circle through that until the quantity is less than 5. the NewItem is a data structure so im not certain how to set that change

[jovial steeple]

Thats alot, and im not sure which part you need help with exactly. If you want to voice call, I can help you easily.

[hasty merlin]

i asked chatgpt to see if it had an idea and it said i cant edit a dat structure directly using code so im going to do a round about way which i think will actually make the code be a ltitle less

[jovial steeple]

Yes you can edit the value of structure varaibles using code.

I dont understand what your issue really is

Other then being confused

[hasty merlin]

im trying to future proof my code. if i were to drop an item from a mob that is 8 consumables and the palyer picks that up, i need the inventory to look at said item and see if anything it has matches (by name). if it does its going to check the quantity it has already in inventory, for example, 3 of said item already in inventory. i then want it to add 2 of those to its already existing spot in the array and subtract 2 from the dropped item. dropped item should now have 6. then it needs to create a new stack by adding 5 of those to inventory leaving the dropped item with 1. then add that single dropped item to inventory. this should leave the inventory with 3 stacks of the dropped item (only 2 of them are full stacks)

[jovial steeple]

So do you need a personal tutorial on how to program this function? Or do you have a specific technical question you can ask here.

[hasty merlin]

how do i subtract fromt he quantity of the NewItem that is a data structure?

[jovial steeple]

What is the newitem

Does this exist on the dropped item actor?

Ok its a data structure

[faint pasture]

Just add this logic, bit by bit

[hasty merlin]

the only part im missing is being able to subtract from the quantity of the data structure

[jovial steeple]

You can use the SetMembersIn<StructName> node to change edit certian feilds of a data structure

[faint pasture]

yes or just break -> math -> make -> set in a pinch

what have you tried?

[jovial steeple]

If you click on it, you can see the feilds you want to edit

in the details

[hasty merlin]

so in theory this should work?

[jovial steeple]

This also works, but I wouldnt recommend it, as if you add new feilds to the structure in the future, you will have to return to this spot in the code to connect the new pins.

[jovial steeple]

This code would remove one quanitiy from the NewItem struct

yes

[hasty merlin]

were close i can feel it but how do i fix this?

[jovial steeple]

I dont know why its read only.

Did you create the NewItem varialbe in CPP?

I dont have much experience marking variables as read only, I wouldnt know

[hasty merlin]

this is all in a function with the input being the NewItem. I set it up so that when i hit "E" it adds an item and passes taht info into the function

and then that variable is what im using

[pseudo tulip]

If you set the readable blueprint in .h, you cannot set it

[jovial steeple]

I see, since NewItem is a standerd function input, you cannot set its value.

[pseudo tulip]

Case Cannot set in the blueprint

[hasty merlin]

so i need to take NewItem and create a var off of it?

[jovial steeple]

You can however mark the NewItem function input as a pass by reference, this will allow you to actualy change its value.

Or you could redesign how this works in general.

[hasty merlin]

still says read only property. ill just turn it into a var and then use taht

[jovial steeple]

I typically have a function output called remaining items, or something along those lines. This output would then be used inside the dropped item blueprint so that it could know how many items it needs to have after the inventory componet was done interacting with it.

[jovial steeple]

This would do nothing to solve the issue

[hasty merlin]

why not? then i can edit it and then continue fromt ehre

[jovial steeple]

A variable on what?

How would this variable translate over to the dropped item

And let the dropped item know how much more it should have left

[hasty merlin]

NewItem input becomes the new variable and then i can edit the quantity. once its fully added how it should be then i can work on the next item i pickup

[jovial steeple]

Im not following

If you want to call, I can help you more

[hasty merlin]

i cant atm since its super late but tomorrow if youre free id love to hop in a call.

my theory is that since the input is not directly editable, i can just promote to variable and edit the variable. once the function is done and the next item is to be added it starts all over

[jovial steeple]

Just dm me whenever tommorow

[hasty merlin]

gracias sir

[naive egret]

hey @lofty rapids I found out the Problem so it was Use cursor as touch that caused the problem with the Actor not being selected once I disabled it everything worked as it should

[astral summit]

Hello , If I have many conditions and many functions, what is the correct way to organize them so that they can be easily reused? Currently, I merge the code into a single event and end up not benefiting from reusing the conditions and functions again

[dark drum]

Hierarchy and good class structure. Adding to that, breaking code into smaller reusable functions. This also allows you to not only reuse the code but override them in a child class if you want to change the behavior slightly.

Plus your code would be significantly more readable.

If you have some code to show, we might be able to offer relevant examples.

[lofty rapids]

glad to hear it works

[tawny hedge]

how can I make sure a timer runs instantly, it doesn't seem to work with time 0 but works with a really low value like 0.01. Needs to run only once

[tall plinth]

I am facing an issue is rotation the trace. It is following the main mesh but i want it to follow the arms? How can I do so?

[tawny hedge]

arms are rotated in 2 different directions, try placing a socket on the arm you want to run the trace off eventually with an arrow to be able to check it's rotation, rotate it to the desired way and trace from the socket location/rotation

or use the camera instead of the actor itself

[lofty rapids]

do once ? why the delay ?

[tawny hedge]

because it depends if it has a delay or not, it can be 0 or another value and it takes values from a data table. So I wanna run the same code if it's either 0 or a higher value and just apply the delay if it's the case. As a workaround I'm using 0.01 default value instead of 0 and it runs, but i'm curious how to actually run it with 0

[lofty rapids]

theres no sense in having a timer set to 0

imo

[tawny hedge]

well, to ignore it, obviously, i tried to skip the timer but the skill doesn't fire that way even if I call the event directly, bypassing the timer.

[lofty rapids]

so the idea is if it's zero don't set the timer ? just branch it ?

[tawny hedge]

I did but the skill doesn't fire lol

it doesn't fire if I set it to 0 either, but if I don't branch or bypass the timer and set the delay to 0.01 it fires

[lofty rapids]

so you want the event to fire if its zero ?

[tawny hedge]

yes

[lofty rapids]

branch it, run the custom event if zero

[tawny hedge]

i did but it doesn't fire lol, that's the weird part

[lofty rapids]

just call the event directly on the zero branch

[lofty rapids]

show code

it should work

[tawny hedge]

this was it's set to 0 in the data table, and it should run off the spawn skill event since it's not higher than 0 but it doesn't. If I do like in the second picture and it's set to 0 it's the same. In both cases if I set the variable to 0.01 it runs both ways

[lofty rapids]

your using get actor location, instead of that, drag out skarms and get location of that, and possibly forward of arms as well

[lofty rapids]

weird i would assume this work, unless the targeting state is making it so it can't cast

[tawny hedge]

the state only changes to casting delay if the delay is > 0. otherwise it's idle by default and it should run

[lofty rapids]

right but it only works when you change that state

as a test, change the state before the > 0 check

[tawny hedge]

well it's fine anyways as I won't have any instant casts without previous animations but was really curios how to run a timer with time 0

[lofty rapids]

you don't run a timer with zero, you do the check and run the function or event seperate

a zero timer makes no logical sense

[astral summit]

Is there a lesson somewhere that provides this information in more detail?

[chilly crane]

Quick rundown, I have a melee trace system.

It fetches all sockets on the equipped weapon, and sets a counter, while looping over that number. It constructs a socket name from the index, and search for it, checks it's valid, and proceeds to a trace if it is, then checks if hit, checks the correct characters where hit, then checks if that particular point has already hit the hit actor. If not, it adds that actor to the list, and does what it needs, then subtracts 1 from the counter. If it is in the list, it just skips & subtacts 1 from the counter. When the counter reaches 0 it sets a var to true again, allowing the timer event to fire off a new trace sequence. However, sometimes certain traces seem to finish before the one set before it. I don't think that needs to be an issue for my given system?

[sharp ferry]

@lofty rapids if I want to make that my character not pick up that exact box but spawn the box from zero on the hand make lots of difference from my last nodes?

[woven sky]

does anyone can help me fix this errors?

[sharp ferry]

i mean when i get close to a box Type,she doesnt pick up that box but generate one of that type in the hand

[lofty rapids]

right so the original is still there ?

[sharp ferry]

yea, i just want that the original box stays there is just like a ''reference'' to what we picking up once we get close

but maybe i should keep this method and once we cooked the product, the box pop out

but for instance

for the ingredtients its better is i dont pick up the singualr bottles, but spawn and use the one static in the space as ''reference'' of what we dropping

you get what i mean?

just the bottles stay there on the table as a ''reference'' of what we picking up'' and once i click E near the bottle, it spawn on my hand but not pick up that one. like if the bottle on the table is a storage item

[frosty heron]

What r you trying to do here?

[woven sky]

I just take all the players location x value (with array) and from there i take biggest value, when one of them has the biggest value then the camera goes to him...

It's a camera manager but for multiplayer

Game

And when I play the game it gives me this errors

[frosty heron]

In multiplayer game, everyone is running their own instance.

Each player have their own world.

So an instance may be valid in one computer but not the other.

[woven sky]

this code is on game state btw

[frosty heron]

Don't matter and calling rpc on game state is weird.

[woven sky]

and run every tick

[woven sky]

true but it works

[frosty heron]

So step outside from unreal,

When is the function triggered? Who do you want to call it?

[frosty heron]

Only for server. Client cant do rpc there as they dont have authority over game state actor.

Why is your function need to be networked BTW?

Is this a server initiated event?

Otherwise what's the point of asking or communicating with others when you want the camera to go to the closest player.

[tall plinth]

This is where it is coming, idk why

[woven sky]

cause to work this sys i need all the players know the x values

of the other players

[frosty heron]

What is x values

[woven sky]

the location of all players

[tall plinth]

How should I make it follow the camera

[woven sky]

the x location value

[frosty heron]

Arnt you just checking the closest player

This is soo simple

It make no sense to have any sort of communication what so ever.

Run function -> get closest player -> do w.e with the camera

[frosty heron]

No RPC needed. Why do I need to tell the server or any other player if I am switching my cam to the closest player.?

Think of a spectator mode in multiplayer game.

Get out from game state.

Do the logic in your controller

[woven sky]

ok

[frosty heron]

Understand that every player run their own instance, they run their own code.

Your job is to sync everyone world so it feel they share the same world.

[woven sky]

ok so if i make this on my controller the errors will be gone

??

[frosty heron]

No

You need to understand how everyone have their own world.

Instance may be valid on a machine may not be valid on mine.

You probably should look at the pinned material.

And see how actor replicates.

[woven sky]

pinned material?

[frosty heron]

#multiplayer

Read a dozen of times, practice, fail, repeat.

[woven sky]

ahmm ok but my problem here is not the replucation lmao

is the validation

[frosty heron]

What validation

[woven sky]

i mean the error says one value is not valid

[frosty heron]

Access none means you are trying to access null instance

If you dont have the variable readily available on the machine that is calling the code when it's expected, then that's your problem.

Read the pinned material over and over.

[woven sky]

you mean the pinned message?

[frosty heron]

Wizard tips and tricks and exi guide is a must read imo

And replication is actually just the basic of multiplayer.

It is unfortunately a beast.

[faint pasture]

OnRep_PawnWeAreAllLookingAt is fine in Gamestate, that's how I'd do it.

And multicasting it instead could make sense if you don't want to have to design around the potential race condition

[sharp ferry]

hi, is it difficult to find devs as revenue share based projects?

maybe on reddit i can find some proper section? do you know any?

[charred granite]

Hey everyone, I'm not sure why my enemy AI wont die when my enemy's health hits 0 or lower. When health hits 0 or -2 for example, then I'll have to shoot it one time for it to die.. This is my current blueprint

To elaborate more on this issue :

So If I did 25 damage per hit for example, I would have to shoot it 5 times.. instead of 4 times .
4 hits should bring it to 0, but it wont die, It'd have to hit it one more time and then it'll die.
I've also tried changing the "less or equal to" node to "equal to", but it doesn't fix the issue.

[full badge]

set health variable before you check health

you're doing the check first

[charred granite]

Okay will do that, thank you so much!

[south yacht]

Hey!
I have ABP and Control Rig node.
In my Control Rig I have Vector var with some data.
How I can transfer vector's data to my ABP ?

[lofty rapids]

what is CR ?

[south yacht]

Control Rig 🙂

[lofty rapids]

is it instance editable and exposed ?

[south yacht]

Sure things

[violet bison]

I want to tether a player so he can't leave a certain distance from the anchor point
how to accomplish it? I think it's using physic constraint

[south yacht]

I enable i/o pin but I have just input pin in rig node...
Is it possible to add out pin ?

[lunar sleet]

What patty said + Actor components

[lofty rapids]

search for expose, what options does it give you ?

[south yacht]

That I can set it as CR spawns or edit it in sequencer and nothing else

[craggy mortar]

Hi

Could anyone here teach me

Why is this all so complicated

[sharp ferry]

i wonder everyday too lol

i watch tutorials, followed a pick up and drop and i was like, how can he start to think this logic his own...

[craggy mortar]

Ye

[sharp ferry]

even if i study how programming works im sure BP is all another world to discover.

[craggy mortar]

Could you help me get into coding or 3d modelling

[sharp ferry]

i wish i could make games my own, even simple stuff tbh but everything in UE seems like sooo difficult for begginers

[sharp ferry]

im totally new to coding im in 3D modelling for 2 years

[craggy mortar]

Could you help me with modelling

[sharp ferry]

what you need to know?

[craggy mortar]

How to make cool stuff weapons beasts

Make houses

[lofty rapids]

#animation might know more about it ?

[sharp ferry]

that's alot of works, especially on UVs, the best advices as people give me here too about coding is the same, watching tutorials mostly

[craggy mortar]

I don’t want to watch tutorials

[south yacht]

Ahh. Thanks!

[craggy mortar]

They mean

[sharp ferry]

and do simple stuff at first, i started doing 3D with a lowpoly bottle, i suggest the same, model it, place seams UV, texture it. the process is always the same

[craggy mortar]

How do I even do that

[sharp ferry]

watch UVs tutorials, and PBR materials how it works

[craggy mortar]

K

[sharp ferry]

also baking from High mesh to Lopoly mesh, with retopoly, and I suggest when u get to Retopology to use an addon that is named ''quadremsher if you're on blender'' also remmeber to work on Symmetry.

[craggy mortar]

Btw how do I make weapons everyone says it is easy but I feel like it’s Albert one styles theories

[sharp ferry]

you mean rifles or sword? knifes?

[craggy mortar]

Ye

I wanna make a boss fight in unreal engine

[sharp ferry]

you wanna start modelling rifles or like swords and stuff like that?

[craggy mortar]

Ye

It’s so complicated

[sharp ferry]

rifles are hard to do. anyway i suggest you to check out ''Hyper 3D'' its an AI mesh generator, it gives a real good base mesh to start with. for instance if i have to make a coat, i start with hyper 3d then i retouch it my own and retopology

[craggy mortar]

K

[sharp ferry]

anyway this has nothing to do with #blueprint so is wrong talking here

[craggy mortar]

I known

Go to DMs

[twilit hill]

Hi everyone, I'm not a programmer, but I'm working on a Blueprint in Unreal Engine to arrange my book meshes side by side in an array.

Right now, I'm using a fixed spacing value to place each book, but this causes problems sometimes the books overlap, and other times there's too much space between them.

What I want is for the spacing to be calculated automatically based on each book mesh's width, so that the books align properly side by side without gaps or overlaps.

In my Blueprint, I currently use a "spacing" variable that affects the X value of the transform location. Instead of using a fixed spacing, I’d like it to dynamically use the width of each mesh.

Can anyone help me figure out how to do this?

[lofty rapids]

probably this would good for bounds

make a point called current position

get the bounds of the new mesh to add

and use that to position it, might work

set the current point to half the distance

or the extent i think is half

then when you go to spawn it, add half the new one, spawn it, add another half

and your at the new point

[ionic solar]

hi

is there anyone here who can help me with a small problem im encountering

[twilit hill]

I think this is going over my head hahah. can you explain a bit more please

[mental rampart]

is there a way to get the camera of player controller 0?

put another way: is there a way to get the camera from the player controller?

[lofty rapids]

theres a node called Get Actor Bounds

[twilit hill]

is this you mean?

[lofty rapids]

you want the actor bounds of the current selected books

[twilit hill]

Yeah my bad, should be actor bound.

[lofty rapids]

you want a variable currentx

basically you'll keep track of the currentx

[twilit hill]

I have a varibale called current position. type vector. is it right?

[lofty rapids]

float

since your moving in a line you can just adjust the x

or y depending on your rotations

the idea is the first you do is move the currentx + the last box extent

which is half of whatever box was last

so you'll need another variable, lastExtent

[lofty rapids]

i just looped over all of them instead of getting randoms

but this is the idea

[twilit hill]

I kinda get it, lets see me trying. thank you man.

[mental rampart]

how do i get the location of the flying camera you pilot when there's no pawn in the level?

does anyone know the node?

[mental trellis]

You can get the current camera location/rotation from the player controller, iirc.

Or its camera manager at the very least.

[north lynx]

Hi!
I have a 3D and 2D character in one level. Using a laptop that displays a 2D character projection by using Scene Capture Component 2D.
I am currently trying to get the player to start controlling the 2D character after interacting with the laptop, but his view stays in place of the 3D character. Unfortunately, the 2D character, despite getting input as planned, does not move on the screen.
Any ideas what I am doing wrong?

[twilit hill]

I though I understant, but I guess I'm too dumb to understand whats going on here. I did it, but doesnt work. the books are separated from each other far way ahhahaha

[lofty rapids]

well your getting actor bounds of self

[lofty rapids]

you want to get the random element, and then get the bounds of that

[lofty rapids]

try get component bounds

[twilit hill]

yeah I'm using mesh array component.

[lofty rapids]

ya get component bounds should work

but save the mesh as a variable

so you can resuse it at the end when you add the mesh

because if you pull of a pure node each time the random will run

so you only want that to run once

[mental rampart]

What setting do I change to lock a shadow in place for a mesh (regardless of its rotation)?

So the shadow doesn't move, it's basically static

[lunar sleet]

I think you’d have to lock the lighting in place

[mental rampart]

is this a setting on the mesh itself or..?

[spark steppe]

i guess you have to render it twice

once for shadow only (without rotation) and once without shadow

[mental rampart]

Good suggestion, but then how do I hide the shadow mesh while retaining the shadow?

[mental rampart]

is there a setting to do the question above

[spark steppe]

no

there's likely no way around rendering it twice

because some vertexes might just be hidden from the renderer when they got culled by e.g. Nanite

[mental rampart]

ok, thanks

[twilit hill]

this is how you mean I guess? but now its overlap again.

[twilit hill]

this is another problem I'm having but not thinking now, as I have to fix this problem hahaha

[spark steppe]

your order of operations is wrong and your variable naming is confusing, LastPosition seems to be LastOffset...

[lofty rapids]

get the static mesh component earlier in the execution, and save it as a variable

[spark steppe]

and each extend is only applied once, while it should be twice

[Extend, BookPos, Extend], [Extend, BookPos, Extend], [Extend, BookPos, Extend], ...

[lofty rapids]

it's missing the add the half at the end

[lofty rapids]

for reference, notice the set after i set actor location

fix those issues and it should be good to go

[lofty rapids]

i don't think this would work because you don't set the static mesh untill after you are getting the bounds

as far as the blue line that goes backward

[lofty rapids]

cache the value, or store it in a variable in other words

[twilit hill]

yeah well this kinda works , but still have some overlaps

[twilit hill]

I see

[lofty rapids]

getting close, whats it look like ?

[sharp ferry]

hi, im practing on a new example very simple thing. i want to spawn an object getting close to a box collision BP. i managed to do it but i only want to make the spawn a little bit forward of my character

[mental rampart]

is it possible to spawn a copy of a mesh from blueprints?

or spawn a copy of a blueprint from itself?

[twilit hill]

its the same, just ad the end value as you said. but my little brain not understant how to connect that get component bounds after set satic mesh xD

[lofty rapids]

ya that weird way you have the blue line isn't going to work

[spark steppe]

this is all so messed up 😄

[lofty rapids]

you see where you get the static mesh and set it ?

[twilit hill]

yeah

[lofty rapids]

move the red, and comming out that get, do promote to variable, and then put that set in the green between the two other sets

then use that variable for you get component bounds, and also for your set static mesh

right now the problem is your getting the component before you even set the static mesh, so it's possible it's the last ones value i'm not even sure

you want to have the value at the green spot in execution, not draw a line backwards

i wouldn't be surprised if you got an access none with that setup and im surprised it even worked

[spark steppe]

ignore the weird y offset, it's because they have different pivots

leavea a lot to be desired, but just to show you how to do the basic math right

[sharp ferry]

i have the problem that now when i spawn an object with Input key E the other things with E like picking up box or start anim stops working

[lofty rapids]

show what the e press event looks like

[sharp ferry]

i added this

i added on the going outside disable input and seems like works, is ok?

[lofty rapids]

is this on collision ?

[sharp ferry]

yes

so when i get out of my box colision spawn

input of that logic disable

is right?

[lofty rapids]

you are disabling input on end overlap ?

[sharp ferry]

yes

in this case only on the box collision

i did this on the bp mesh

no my character

do i even need a player controller on that disable input?

[lofty rapids]

read what it says when you hover it

it says what it does if left blank

is this one player ?

[sharp ferry]

the player controller?

''get player controller'' u talking about?

yes one player

[lofty rapids]

the input that your asking about if you need

[sharp ferry]

but reading the description is not understandable at all

[lofty rapids]

hover over it

basically no you don't need it for one player

[sharp ferry]

aah

because i already have ''self on the enbale/disable input right?

since i've already ''self'' on these i dont need to make clear what player again

right?

[lofty rapids]

no ... if you leave it empty you just disable ALL instead of selected

[sharp ferry]

removing it it doesnt spawn anymore

empty u mean on 0?

[sharp ferry]

is this the way i should read this?

[lofty rapids]

except your casting to nadine so what is that, if that is successfull the rest runs, so basically it only runs if overlapping nadine

[sharp ferry]

casting nadine is my character nadine

means that when my box collision overlap with my caspule of nadine event starts

no?

[lofty rapids]

ya it should be if the thing overlaps with your character

[sharp ferry]

yea If

thst it

[twilit hill]

sorry to bother you by having another question, but why my random doesnt have an executio pin?

[north lynx]

Any ideas on this? I'm literally loosing my mind over it

[spark steppe]

doesn't matter in that case, if you are on 5.5 you can rightclick it and pick "show execution pins"

[lofty rapids]

so it switches to the second player at all ?

is this multiplayer ?

[twilit hill]

thanks so much. was frustrated for 3 days with this. Not a blueprint guy, never used that much. Needed to do this for the project I'm working for automate the proccess.

thanks to @lofty rapids aswell for all the help.

[north lynx]

Nope, I'm trying to make 2D minigame inside the 3D world.
Trying to see the minigame through laptop screen, when playing as the 2D character

[lofty rapids]

ok, and what happens exactly, can you see the character, but it just doesn't move ?

[north lynx]

I have 2D Character on the map and can't make him move, even if the input works

[lofty rapids]

so your character is actually firing off the input events ?

[north lynx]

I have print string on the end of the movement 2D, and I can see that it responds

Yet the character still stands in place

I'm unpossesing the 3D character, possesing the 2D character on map, enabling the input, and loads the IA_Move2D for inputs for 2D Character

[lofty rapids]

show the movement event

[north lynx]

In Character 2D Blueprint

[lofty rapids]

print string your values

make sure the axis values are comming back correct

[north lynx]

Values are correct

[lofty rapids]

set the x to 10.0 one way, and y to 10.0 the other

he should start moving

[north lynx]

Nope, still standing still

Even 1k doesn't work

[lofty rapids]

i c so your values should be correct and it print string

so it's just not moving

[lofty rapids]

is this character or a pawn ?

[north lynx]

PaperZDCharacter

[lofty rapids]

oh idk anything about that

but you could hard code the movements as well

[north lynx]

It's plugin for making 2D games in UE

[lofty rapids]

ya i've heard of it, i just don't know what the character has and doesn't

what do the components look like in this character ? is there a movement component ?

[north lynx]

Yep

[maiden wadi]

It's a normal character that uses a sprite instead of 3D mesh.

[lofty rapids]

as a test lift him up off the ground to be sure he's not in the floor at all ?

does he fall like normal on to the floor ?

[north lynx]

oh my gosh

8h of my work, he was stuck in place for some reason

[lofty rapids]

he was probably spawning into the floor

making him not be able to move

[north lynx]

Yeah, makes perfect sense, I just didn't think of that

[hasty merlin]

how would one reccommend setting a mesh? i want to have a couple items drop from a monster upon its death but im not certain how to set its mesh. I know i can set static mesh but to choose the correct one for each automatically im not sure of. should i just store the static mesh with the item data in my data structure? or is there a much more efficient way?

[north lynx]

@lofty rapids Thank you very much for that journey 🧡

[lofty rapids]

you could store the static mesh with the item data that would make the most sense, but i always like a map of uniqueID as string, to static mesh

it's fast lookup time

and you can get the keys, shuffle, and spawn them

[hasty merlin]

Map of uniqueID?

[lofty rapids]

ya, uniqueID key, value is a static mesh

[hasty merlin]

so if i wanted an RNG setpu of say leather, bones, earth crystal, each word would be a uniqueID and then it could set all of that into my fsitemdata?

[lofty rapids]

"should i just store the static mesh with the item data in my data structure" ? what data structure are you using, if your getting a random item from this then just use the same structure you already have the item

[hasty merlin]

ignore the bottom 2 i just set them for testing. im planning of different monsters to fight. each monster has a chance of dropping 1-4 items of specific types but i dont want to hard code the FSItemData ehre into each of those for every monster. id like to input just a single string and then it will auto set all of the info autimatically into the fsitemdata

[lofty rapids]

so i would probably make a function that builds the structure based on the string

[hasty merlin]

what about if i could set every item ahead of time except for quantity and then select that and it will autofill everything i need?

[lofty rapids]

just have an array of structs

and get a random one

you can edit the struct after you retrieve it

either an array or a map of structs

and build it out either randomly or manually

[hasty merlin]

whats the difference between array, set and map?

[lofty rapids]

an array is just a list of the type of variable, so an array of string, or an array of numbers

something you can iterate through and access based on index

index 0 is the first, index 1 second, etc...

so theres no real id there other then the index

[hasty merlin]

what about set and map?

[lofty rapids]

as far as map goes its a key valye pair set, so it's basically a list of key/value pairs, if your key is a string, and your value is a static mash, you can find based on the key say "some item"

and that would retrieve the static mesh

assigned in the same key/value pair

idk much about a set, but it's something to do with a list of unique items

tbh i never need it

[hasty merlin]

so if i were to set the key to be a string say "SwordOfAwesomeness", could i set the value to be the FSItemData?

[lofty rapids]

yes for sure

[hasty merlin]

and i can set all of that info inside the map?

[lofty rapids]

yep

[hasty merlin]

icon, static mesh, itemtype etc?

[lofty rapids]

try it out

[hasty merlin]

i tihnk a map is exactly what im looking for

[lofty rapids]

i usually prefer it for a lookup because it's O(1)

Altho "accessing an element by its index in an array is indeed O(1)"

it's easier to remember and look up with uniqueids

plus you can get the keys, and get only things with a certain prefix

stuff like that is cool

you can get the keys, get a random element from that array, then find that string in the map for a random item

[hasty merlin]

where would you store the map? inventory actor ocmponent on firstpersoncharacter?

or just like another actor taht i place in the world so everything can access it?

also it would be more like a sequence with each pin having a chance to spawn set item and with quantity range of X

[lofty rapids]

if you wanted a good random you could do weighted sum, i don't know the chances with the random node probably 1 in however many there is for each one

[lofty rapids]

are you going to be loading an unloading levels ?

[lofty rapids]

you could make a item manager actor, thats not a bad idea

and just drop it into the level

this way you can have things like the random function you can run as well

but i put most of the stuff i want to persist in the game instance

[hasty merlin]

im not certain yet to the scope of that portion, it might just all be one level. a openworld actor that i pop into the level should be fine right? then i can pull from that and affect the inventory component and not worry about casting

this looks correct right?

[lofty rapids]

as long as it's all base stats and your not modifying it on the fly

[lofty rapids]

yes thats correct

[hasty merlin]

wont be modified at all. do i need to click instance editable or blueprintreadonly at all?

probs not instance editable

and expose on spawn?

[lofty rapids]

i mean i don't think you need them, should you need them they are there

begin play -> get actor of class -> promote to variable

use the variable to access the itemmanager

[hasty merlin]

and in my enemy bp should i have a special function for choosing the drop chance? im thiking in the parent of it all atm

ItemDropChance() function that has you input up to 4 strings and then for each string, runs RNG then sets quantity in another RNG and outputs the strings and quantity to be used in EnemyDeath() which will take that info and spawn droppeditem with stated info

[lofty rapids]

whatever works

what is RNG ?

Random Number Generation ?

[hasty merlin]

random number generator. i want to set each additional item to be less and less. 100% for first option, 50% for second option, 15% for third option and 5% for 4th option. each run separately

so i could have 1-4 drops. if i get 2 drops it could be the first and 4th option or the first and third option etc

[lofty rapids]

#game-math might be better for this theory of random numbers

[hasty merlin]

ill check out tehre after for the RNG. i just need to get the rest setup to correctly find the info

[lofty rapids]

ya maps are pretty simple to use, find the key, get the value

if you add the same key, it overwrites the previous

[hasty merlin]

can i switch on string from array?

i ahve Items array for testing and its a string

im thinking something like this where i set the items in the child which will be the physical enemy and then it inputs into the drop chance. then on each string it runs to do its RNG stuff and output quantity and string for each item

i guess if i throw a ofr each loop in there

[frosty heron]

Comparing strings is nasty imo

Use gameplay tags

ItemRarity.Common
ItemRarity.UnCommon
ItemRarity.Rare
Etc.

[hasty merlin]

something like this. but how do i set the storagedata adn then pop that into droppeditem?

[red briar]

can anyone spot whats wrong? ive been debugging for a while but idk what im doing

it selects the last item each time, its a random number generator with probabilites

[lofty rapids]

you want a foreach with break

[lofty rapids]

then break on true

so that when you hit true, set the response value, then break, it doesn't do anymore checks you have found the value

[sharp ferry]

hi, where can I try to propose my game project idea as revenue share project?

[red briar]

this works better but it selects the same one a suspiciously high amount of times... might just be that all my probabilities are the same though

ill do a bit more debugging rq

hmm...

[lofty rapids]

make sure total is set to zero before you start

[sharp ferry]

i see the #rev-share-jobs but how can i add mine?

[red briar]

it is

i got it now

thanks a lot for the help, you got me in the right direction :)

was doing this subtraction wrong

its working now, thanks a lot

[lofty rapids]

ok it i would not pull from the setter all the way to the other side, i would use a fresh getter

[red briar]

yeah thats a good idea, ill do that

[lofty rapids]

oh right i c you had them flipped

[sharp ferry]

i managed to post mine

[faint pasture]

fresh getter gang

every getter is fresh

[fleet prism]

Is someone able to point me in the right direction? I'm trying to get this crate to explode on impact I want to be able to hit it just once and have it fully explode but I cant seem to get the desired effect It also moves when shot at which I don't want. I followed this tutorial "Introduction to Chaos Destructible Mesh in Unreal Engine 5 - Learn The Basics in 7 Minutes!" but cant figure out how to make it how I want it to be. I tried to find other tutorials but to no avail.

[steel shadow]

First follow tutorial exactly, then fiddle with settings. Noob guess is that whatever threshold of 'damage' you need to destroy the mesh you have set way too high.

[broken wadi]

Are you adding a transient field at some point to affect the physics of the geometry collection?

[warm hare]

What do I need to add to my door logic to make it auto close if I leave it open?

[lofty rapids]

possibly set a timer to fire off the event again within a certain time, set the timer handle to a variable, then invalidate it when you close ?

[faint pasture]

Finished -> delay -> switch on Direction -> reverse would do it in a pinch

assuming direction is valid long after finished, not sure if it is

careful though, you have 2 states representing what the next interaction with the door should do when you should have 1

assuming direction is persistent you should use that as your state. It's the last direction the door went, either opening or closing

then you can lose the flip flop and the do onces

[fleet prism]

no

[broken wadi]

https://dev.epicgames.com/documentation/en-us/unreal-engine/overview-of-physics-fields-in-unreal-engine

When projectile hits box add a transient field so it does physics stuff. Alternatively you can just make a new BP with only the transient field(s) in it then spawn it in at the impact location so it can be used with other explodeable actors too.

[warm hare]

So I am getting lost. It should look like this?

[warm hare]

All I want is for when my character opens a door and walks through it closes after 3 seconds automatically. I feel like it should be easy but am unsure.

[last peak]

it is pretty easy you just need a timer set to 3 secs

[warm hare]

I am still new. Where do I place the timer in my logic?

[last peak]

What do you think where you should place it?

What do you want to do?

[warm hare]

Basically. When I open the door It will either close after walking through it after 3 seconds. So I imagine I would place it after my timeline

[last peak]

Seems lik a good idea, so after the timeline you create a timer by event set it to 3 secs and connect a custom event to it

Now you just do your entire code to open the door inverted

[warm hare]

So essentially flip the sequences?

[muted mason]

How can I make a loop action without using the event tick? I put this but it only appear once, I don't know if I need to triggering again since I checked loop on the set timer by event, pls help this is the first time using ue xD

[steel shadow]

You need to connect the 'event' pin to the event

And define an event by right clicking and type 'add custom event' and select what comes up. You can name it what you want

[muted mason]

Ah so basically the script runs when the begin event is happening, but the loop itself is an event

[last peak]

There are a few ways, what are you doing in your timeline? on update you get a value out of your timeline track and set the rotation of your door to it
You could just multiply that with -1 and play the timeline from start

[steel shadow]

The loop is not an event, it calls an event on repeat

Connect logic to your event you named 'loop' and that logic will run every 3 seconds unless you manually stop it

[muted mason]

This is working

[steel shadow]

That is an infinite loop

[mental trellis]

That would work if you unticked "looping".

[muted mason]

Yeah

But if I put something on false it should stop, right? But will check constantly if it's true or false..

Will that be hard on cpu or smth like that?

[mental trellis]

You'd need to check before re-entering the set timer node.

[last peak]

Its probably the dirtiest way of how you can create a loop

[muted mason]

How could I do it without breaking my computer cpu? xD

[mental trellis]

There's nothing cpu breaking in that blueprint... if you untick looping.

[last peak]

You wont break your computer but what are you doing is

You start the game
you set a timer- the timer triggers the event loop then the timer gets destroyed and you instantly create a new timer that triggers the loop after x amount of seconds

[steel shadow]

Oh yeah I forgot that about resetting timers

Otherwise it would just hang

Eventually lol (actually still think it would hang eventually right with 2^n calls at 3n seconds)

[muted mason]

Ok so, if I uncheck looping, they will only to the timer once, so I can let it check so I have something that is constantly checking a variable

[mental trellis]

Checking a variable is fine.

[muted mason]

I basically wanted a tick event but after a delay time, not every frame, I don't know how good it is

[mental trellis]

You can set the length of tick.

Not sure if BP accessible.

[last peak]

event begin play - set timer by event 0.1 sec, looping, connect that timer to the loop event and there you go

now the logic in your loop event gets triggered every 0.1 secs

[muted mason]

Is this looping event hard on usage? I was thinking I could use this to check if there is something in a certain hitbox area

[last peak]

Well its cheaper than tick ...

[muted mason]

Like, if any objects are in this cube hitbox area they get instantly destroy

Actually I think there are blueprints made for that

[steel shadow]

How long is a piece of string

Doing it per 0.1 seconds is better than tick whatever it is

[last peak]

Exceptions are things like animations, you need them on tick

[muted mason]

For now I want to understand how to properly use blueprints, I watched a 1 hour tutorial and I only got some basics

Now as a normal person I will start practicing by creating elden ring 2

[last peak]

Ye, timelines and timers are one of the first things you want to learn

Do you have any coding experience whatsoever?

[muted mason]

timelines being the order of the blueprints?

[muted mason]

I code a bit in GML, I had to learn Unity for college but I am bad at programming, I understand the logic but I don't know the language, I only focus on Game Design and 3D Modeling

And by "learn Unity" I mean I mostly copy and modify what chatgpt was cooking 💀

[last peak]

You need to know the different datatypes, that should be number 1
What is
A bool, integer, string, vector, float

Then absolute basics, build a blueprint that prints hello world to the screen as soon as the game starts

Then how to create timelines and timers, what your doing right now

Blueprint communication, how and when to use casts, interfaces and components, what are references and pointers

Create a second blueprint that prints hello world to the screen when the player presses e, keep all the printing logic in bp2

[muted mason]

I made a game in block coding on a website called Thunkable, I understand the logic of the coding, I know about the variables and stuff, it's like I know the gramar and the time articulation but I don't know the word itself, I don't know what bp should I use and when, as you said I need to learn more about it

Also, I put the bool on false, it display the good text, and I uncheck the looping, but the event is still looping in the game

[last peak]

can you explain from event begin play what happening in the code with your own words ?

[muted mason]

The game start - A timer of 3 second start - At the end of the timer it's an if branch, if the variable attached to the branch is true, will display the top text that is true, if it's false, then it's the bottom text, and the whole timer/check/display is a function that I called Loop

Ah, I know

It's because I link the function with the.. function

[last peak]

ye dont do this

loop shouldnt be connected to the timer

it should be connected to your branch

[muted mason]

You mean the if branch? But on the if branch it's the variable that is checked

ah, you mean the white wire

But in that case the loop function won't have the timer inside it

[steel shadow]

Connect your node called 'branch' to your node called 'loop'

[last peak]

ye

like that

[steel shadow]

Disconnect the branch coming off the set timer

Or tbh does not really matter but I think you still don't quite understand

[muted mason]

You mean like this?

[steel shadow]

Yes

[muted mason]

Ah, it's working, but in that case, when I reffer the loop function somewhere, it won't have the timer included

[steel shadow]

Now your 'loop' event that your timer calls every 3 seconds, will perform the check at seconds 3,6,9,12 and so on forever unless you end it

[last peak]

So you would create another custom function and call it set timer, then you connect it to your Set timer by event node

[steel shadow]

The timer is not contained in the event. The timer calls the event

[muted mason]

Yeah, but could I add it in the event so when I call the function, it will have the timer (with the loop), the check and the display

[steel shadow]

It's good that you are avoiding tick when it's not needed, that's good coding practice

[muted mason]

We made a game in Game Maker, it was something small but we got fps problems because we made almost everything in tick xD

[steel shadow]

You can set actor tick in settings

If you run everything on tick, you can adjust tick rates per actor

Save you redesigning everything

[muted mason]

I will try to avoid using it, and only keep it for things that need to go very smooth or stuff that I don't know how to set up otherwise

Ok, the timer is not something hard to add in front of the function, thanks for helping me guys, I understood a bit more how the event call works

[steel shadow]

Tick is basically an event that calls every frame
So if you have 100 frames per second, it's like a 'set timer by event' triggering every 0.01 seconds

An event that calls every 0.1 seconds is 10 times more performant than that

[last peak]

Its bad practice almost always because it also makes your code framerate dependant

[muted mason]

Yeah, I hate that all the games in this days have bad performance, so I will try to optimize them how I can xD

Same with my blender models

[steel shadow]

Well, not if you have custom tick rate @last peak

It's usually just 'hero' units you run per frame (or animations ig),a lot of stuff you can get away with 0.1 second ticks or 0.5 seconds if they don't have anims

[muted mason]

How can I fast delete a link without right clicking on the node?

[steel shadow]

Alt click the link

[muted mason]

Is it a good idea to create an actor with a lot of code in it and put it in the scene as a main "data base", or is better to split the code on multiple actors, like some on the character, some on the mobs, etc (more for random stuff not for basic functionality like character walking or anything like that)

[last peak]

Put the code where it belongs to

you should encapsulate as much as you can

and use a lot oomponents

[muted mason]

I was thinking to make a actor with functions, and then on the other actors call upon the functions

The actor would act as a functions library xD

[last peak]

Thats dirty

[steel shadow]

Probably better to organise things to try and minimise unnecessary cross actor referencing

Unless your game is huge probably won't matter performance or memory wise, but might get confusing

[last peak]

For that you have components

[muted mason]

Ah ok

[last peak]

A component is like a backpack with code that you can strap to any actor

[muted mason]

So you will do less cross referencing because all the actors you're working with have the functions ready in their own script?

Well, thanks for the help again, I will go to sleep for now, good night 😅

[steel shadow]

I prefer my 'moms spaghetti' method of code organisation

[charred granite]

Hello, I can't get my enemy AI to spawn on my locations. Maybe I'm overlooking something but I cant seem to find the error in my blueprints. I've also deleted and re-added the navigation mesh, but the result remains the same, my enemy AI don't seem to spawn on the given location. Here are my nodes from my Game Mode Blueprint.

In the world settings, I've also selected the correct Game Mode that I created for the level

[steel shadow]

Where are you setting your spawn locations

Also the right screenshot, can you show a larger version?

[charred granite]

I've placed 2 enemies in the map, copied their location as a reference, and pasted that into both variables SpawnLocation1 and SpawnLocation2, as shown on the right picture node.

Sure, I'll try to take a larger picture, I'll have to split it up prob. Wont fit my whole screen 😆

[steel shadow]

Try adding say 50 units to the zombie z spawn. Could be they spawn too low clip the ground and it gets ignored.

[charred granite]

I'll try this, Z axis is currently 15

[steel shadow]

If those zombies are there already and they collide with each other, the spawn might also get ignored

[charred granite]

Well I deleted them after setting the location, only used them as an indication

[steel shadow]

Transform also contains scale

Are you copying the scale too?

[charred granite]

Larger version of the node, I have to split it up as it's too long 😄

[charred granite]

I just checked the scale and its the same too

[steel shadow]

Well that should spawn at least one zombie

[charred granite]

It doesnt seem to work unfortunately

ill keep looking

[steel shadow]

What situation is this occurring

You have it in game mode begin play

But that can trigger before you load the level

Do you travel to the level from somewhere else? Eg a menu level

[charred granite]

Well, I'm supposed to head into a main menu first, before actually loading in the level where the zombies are supposed to spawn

so maybe that's causing potentially issues

[steel shadow]

Well yes if that menu level uses the same game mode

Pretty sure begin play will call in the menu level

[charred granite]

The main menu level does have a different game mode blueprint that I created

[steel shadow]

But you can call your 'start game' from inside the level blueprint

[steel shadow]

And it uses it as default?

[charred granite]

my default game mode is set to the Main Menu one, as I want to load into that first before the level starts

[steel shadow]

Put some print strings in your spawn code, might help you see what is going wrong

How does the menu > zombie level transition occur?

[charred granite]

I set up a Widget blueprint for the start/main menu, and then I created the following node for start game :

The thing is, even during the editor the zombies wont spawn, it's not in the packaged game but even in the editor

[steel shadow]

Ok well put some print strings to see what's happening

Btw I just realised if you have current wave = 0 that won't spawn anything

[charred granite]

Ill try changed them to 1 and 2 instead of 0 and 1

I thought UE used a zero index?

[steel shadow]

Yeah 0 won't spawn stuff

It does but your setup doesn't accommodate that

[charred granite]

I tried with other index but same result unfortunately

[steel shadow]

Well 0 will never work, now add some print strings or breakpoints

Where do you set 'current wave'

[charred granite]

You actually ask all the right question, thank you so much. I found the issue

The current wave was set to 0, so I changed it to 1 and that solved it. Took me hours and hours, should ve asked here sooner

[steel shadow]

No worries, I am very bored tonight

[charred granite]

haha

thank you so much man! appreciate it

now I can finally sleep haha

[celest bluff]

I am using Unreal Engine's Default ABP_Manny animation. I am trying to designate the mannequin to "look at" a pawn. Right now I cast to Unreal's Default BP_FirstPersonCharacter (I installed both first and 3rd person start up files) and looks only at the player.

There are many things that I want to do, but what I want to do first is to identify how to set an instance editable variable for an array of pawns (that I designate to look at). I can figure out the rest.

[surreal peak]

You'll need to have an overlap sphere in your Character that registers overlapping Pawns. And on Begin and End Overlap of this Sphere you'd want to add and remove the overlapping actor to and from an array (after casting it to Pawn or Character!). That array would be a variable you have to create inside your character class. Presumably of type pawn.

Then you can get that array inside your AnimBP. Or you add a function to your character that loops over the array and returns the closest entry and call that in the AnimBP.

Player Index and GetPlayerCharacter aren't the right thing for that.

That's a local coop thing for player controlled characters only.

[celest bluff]

I do have a trigger zone for that type of thing and I was also thinking of using pawn Sensing instead (yes I am working with AI, but it is irrelevant atm). I was thinking I could use "On See Pawn" and threshold rather than on enter and on exit.
But yeah, I was asking about how to replace the cast and allow for an instance editable variable array of pawns.
From what I'm reading, I should just use an interface.

[paper smelt]

I suck at math, can someone please tell me how to make the mouse actually move the widget interaction component all the way to both sides of the screen?

So. I'm having an enum problem. I have a gun that can fire different types of shots. I was planning to use an enum to switch between the shot types, for ease of use. But uh....when I try to use this, the enum won't switch what's it in. This screenshot shows something to fire the earth shot, then switch back to basic bullet. This never happens. Instead, the earth shot keeps firing. Is there something I'm doing wrong here? I am on 5.4 if it makes a difference.

[paper smelt]

Im prob wrong but it looks like right after you call the event you set the bullet type instantly so nothing happens

[celest bluff]

What do you have controlling or directing the enum selection on play?

[paper smelt]

This too

[void glade]

At the moment, nothing. I have functionality for that, but it doesn't work, due to this. I'm trying to isolate what's causing this first.

[paper smelt]

Can you try to put the set enum in your function

[void glade]

Did that. It never triggers. I put a print statement in to make sure the statement was being reached. It was.

[paper smelt]

Cuz you set it back to default one instantly so if you have any checks with the enum its not going to work

[void glade]

It just says "Nah, I don't feel like it."

[paper smelt]

Are you able to call in pm?

[void glade]

Hmmmm? Call in PM?

[paper smelt]

Call in personal messages

so like a 1 on 1 call

so we dont bother the people already in the calls

[surreal peak]

Instance Editable Variable makes no sense here.

[void glade]

Sure thing.

[paper smelt]

Ok ill priv message you call when you want and we will fix your issue

[surreal peak]

If you need to address multiple actors that do this share a parent class then you can just keep an arrays of actors and ensure they have the interface to retrieve the look at location.

Otherwise it's enough to have an array of the Pawns/Characters

But you need to construct the list/array runtime. Either via overlaps or pawn sensing or whatever else you want to use. Instance Editable is for selecting already existing actors in the scene. That doesn't scale well at all.

[surreal peak]

You gotta connect the enum variable to the switch node :P

That's probably all there is to it

You currently set the switch to always be the same value

It's an input after all

[celest bluff]

Everything here is edited and changes before the game plays. On play, things change.

[surreal peak]

Yeah but that's not what you use for sensing other Pawns and looking at them

That's a nightmare to keep updated by hand and won't take into account runtime spawned actors

[celest bluff]

I need to change only once and it's permanent.

[surreal peak]

Still not how you do this

That's just bad design for this feature

Anyone know a good guide where I can try to replicate the Xenoblade battle system?

I'm having issues with Attach Actor to Component node.

Using my interact system I want to "grab" an item from the floor, attach it to a scene component in my player BP so it's visible in my fpp view.

The attach node returns "true" so apparently the attach worked, but it has no effect on the item - it stays on the ground.

What am I missing here?

[last peak]

You have no socket specfied

[tropic peak]

I don't need a socket 🙂

[sharp ferry]

it's difficult to make a siystem where my character clicking key E on the door teleport on a nother room?

[tropic peak]

it's not

[sharp ferry]

as a begginer is accessible?

[tropic peak]

you need an interaction system (even basic)

[sharp ferry]

i guess i just need to set up a different spawn zone on an input with box collision?

[tropic peak]

first step - learn how to interact with the door actor

can be based on overlapping collision boxes

[sharp ferry]

got it, i will try again as a spawned the money on the box collision with Gemini goolge

yes

[tropic peak]

there's a ton of tutorials on this and it should give you an idea on what to do next

[sharp ferry]

gemini managed to help me to understand fully the process of spawing an object with my character on a box collision

when overlap

[sharp ferry]

and swap clothing of my actual character when teleport too is hard?

i guess it requires to make another BP character

[tropic peak]

nothing is hard, some things just take more time. you can do it

[sharp ferry]

because rig is diff

[tropic peak]

i can't help with clothing/animations, it's something I'm terrible at

[sharp ferry]

got it ty anyway

[tropic peak]

skip that for now and make sure the player teleports to the right place

[dark drum]

Chances are the static mesh component in your item isn't the root of the actor meaning it was simulating inside itself.

[sharp ferry]

i dont understand why my movement in UE5 with click right and wasd became soo slow

[full badge]

try set the actors location

[tropic peak]

it was an issue with the child actor, it overwrote the masters function

silly mistake

[lofty rapids]

is the game lagging ? or your just moving slow ?

[sharp ferry]

i fixed restarting, but i dont know what was causing it

waasnt lagging

[lofty rapids]

probably just a bug, if a restart fixes it thats usually the case, unless you didn't save and something you changed got reverted

[charred granite]

Maybe I'm understanding the logic incorrectly but my zombie spawn logic doesnt want to spawn 20 zombies total, divided over 4 different locations, so should be 5 per location.. It never matches and is always incorrect. My blueprint below, I split it up in different pictures as it's pretty long

It only seems to spawn 15 total

[lofty rapids]

what is current wave ?

[charred granite]

its set to value 1, when I set it to 0 they wont spawn

[lofty rapids]

makes sense

[charred granite]

guess ill just leave it broken like that, no idea why its acting like that

it works but it doesnt seem to spawn the even, correct amount

[lofty rapids]

one sec... i'll show you what i would do instead of this multi loop thing

[charred granite]

kk, thank you for the help btw. You guys are awesome

[lofty rapids]

this will spawn 20 items with 4 different transforms

just set the array of transforms index 0,1,2,3

to be the four transforms you want

but this spawns the same item

[lofty rapids]

this works for the same item, if you want different items per spawn, make an array of class names and pick the corresponding index

so you basically link the two up

get the transform, get the classname

from the two seperate arrays

or you can use an array of structs which hold the transform, and class reference

either way works

an array of structs is easier to maintain, but the two seperate arrays with matching index works as well

then you can use last index as your total spawn, and the amount in the % is the amount of spaces

just make sure you have the proper stuff in the array, which i would probably do some valid index checks or something but this is the basic idea much simpler then the multiple loops solution and it works

i've heard structures in blueprint could break the project

so two arrays might be better, if this wasn't an issue i would use a struct instead because it seems most fitting

[charred granite]

I'm pretty new to blueprints so it's a bit confusing rn tbh, I'm also not sure on how to get those orange and purple "GET" array nodes

[lofty rapids]

they are arrays, it's a good type of variable you can use i use it pretty often

[dark drum]

Orange is normally a variable type of 'Transform' and the purple indicates a variable type that is an object class. (This could be any class but in this context it'll be an actor class). The dotted grid just indicates that its an array of that type. (list that can hold multiple of the var type)

Hello everyone 👋 does anybody know how to package a project with Retina compatibility for Mac ? I'm on M1 Pro but when I package the project it is blurry like it doesn't apply retina resolution...

[pure gyro]

have you tried any of these options:
https://forums.unrealengine.com/t/how-to-properly-build-for-mac-app-and-retina-compatibility/2584686

[lofty rapids]

also ...
https://www.youtube.com/watch?v=HXCkOzkgamU

[lofty rapids]

but i think as to your original problem, your increasing the starting index, if you set the indexes to start at 1, and goto to total/4 on each loop it should be fine

just loop 1 to total/4 four times

[elfin lagoon]

i need to make gate passible through for one team and not passible for another
but changing collisions response dont look like a good idea, bcz in the middle of action characters of a different teams can be close enough to enter, when collisions response is changed
how to do it in a right way?

[lofty rapids]

"teams can be close enough to enter, when collisions response is changed" <-- i'm not sure what this means

[lofty rapids]

"i need to make gate passible through for one team and not passible for another" probably custom collision channels

[charred granite]

I've tried changing the indexes as well but it remains broken.. Thank you for all the information, will have a look at it and let it sink it. I'm new to this and it's still confusing me honestly. I'll try to find different methods in the mean time, this one wont work for me at all sadly

thanks tho guys, really appreciate you taking the time to help me and create blueprints to show alternatives

Also english isnt my native language so certain objects/topics are a bit hard to understand with specific terms. I guess I need more time and practice

[elfin lagoon]

situation: character 1 from the team1 near the gate. character 2 from the team2 following character 1
collision response changed to let char 1 enter, end char 2 also enter, bcz collisions dont switch back yet

[lofty rapids]

why would you do that, you should use two custom channels

one for team A, one for team B

and set the gate to block for the proper team

[vapid hatch]

so im importing 2 blueprints from a colleague

we have a common code/blueprint base, so it should just work
it finds the references to most other BPs correctly, but there is 1 it doesnt find. its another blueprint, it exists with the same name in both our projects.

but because its not found on the first loading attempt it just gets deleted immediately without me being able to fix the reference or anything, so now i get errors that the components are missing

anybody know how i can fix this?

[lofty rapids]

create two custom channels, one for Team A, and one for Team B

default it to ignore, and set the opposite team players to block

or default it to block, and set the aligned team to ignore

[lofty rapids]

are all your characters have a parent class ? do you have two seperate parents classes for the seperate teams ? or are all your characters seperated ?

you may want to set the channels on load get all your characters and do it automated

depending on how you have your characters setup

[lofty rapids]

wdym "deleted immediately" ? the actual component, or the reference ?

are you getting accessed none ?

[vapid hatch]

and it disappeared from the component overview

as soon as i load/open the relevant Bp

[lofty rapids]

so you have broken stuff that use the component ?

[vapid hatch]

its broken because it doesnt find the components blueprint for some reason

the class/blueprint it should be using exists, but it doesnt use it for some reason

[frail spade]

Hi, all. I feel kinda silly asking this, but is there a comprehensive guide for integrating Steamworks API? Stuff like detecting the Steam overlay and adding achievements? I've found a lot of guides and info, but a lot of it seems to be outdated or missing information. I'm also a first-time game developer, so some of it is going over my head. Halp?

[storm solar]

I have enhanced input setting and am setting up a key binding menu for the player.
As an example I have an input maping context that has a confirm action.
The inputs for this action are the enter key on the keyboard and circle button on the gamepad.
When updating the binding for these keys using map player key, all actions that have multiple keys get rebound to the last input in the action set.
So if the confirm action has the enter key and circle button, both inputs are now set on the circle button and not the game pad.

[inland walrus]

this is creating the buttons and setting the button text correctly, however the map value is only printing 1 value doesnt matter which button is pressed.

[lofty rapids]

i think because the event runs later your not getting the current value like you want

[inland walrus]

I'm not sure I follow

[lofty rapids]

you want when you click the event runs and pulls the proper map value correct ?

unfortunately that event is running "later"

and pulling from that value when it runs

which is not the current one in the loop

[inland walrus]

Ah so I shouldn't use this method?

I thought I was on to something using a map xD

[lofty rapids]

well everything is ok, this is a classic misunderstanding of execution flow

the loop body runs

but the click event doesn't happen untill you click

and when you do that, is when it pulls from that pin

[inland walrus]

I see

[lofty rapids]

its not really a map issue

[inland walrus]

Is there a way I can still use this method or should I find a new one?

[sharp ferry]

I was thinking about the whole systems of cooking the "product" picking up every singular reagent/bottles... is gonna be impossible to me. I tried to follow Gemini to help me with the first pick up the first product (not really picking it up but spwaning the dame type once overlapping collision) i totally got blocked when i have to set up the animstion in the ABP.... i dont even know how to do it

I did that following a tutorial about picking up snd dropping, now i have that system with a different holding animation on the dame BP chsracter i dont even know how I could implement a new one there

Why it all had to be so difficult in.UE

[lofty rapids]

probably a new one, this is a tough way to i'm trying to get it to work but its tough one, or maybe someone knows the way but i can't see because clicked doesn't have any inputs or outputs you can set

[charred granite]

So took a little break and watched some videos and managed to create this exact node now without issues, but still wont work. The zombies only spawn at one location and wont spawn at the other one's added to the arrays. It will only spawn 5 zombies at one location, not at the other locations.

[lofty rapids]

because your spawn classes array only has 1 item

do all four

[charred granite]

oooooh

omg 😄

[lofty rapids]

if you want to spawn the same thing just set them to the same

it was probably throwing a accessed none or something

[charred granite]

kk makes sense now,, will try it

[lofty rapids]

thats why a structure would be better, but blueprints structures can be quite a hassle

but this way you just have to keep the indexes matching up

or you could say if there was no valid index in that array, set it to a default as well

to make up for mismatches

[inland walrus]

damn okay

[charred granite]

its fine, I was actually planning on making 3 more other child classes from my enemy AI to add to the arrays. It works now too, thanks a lot!!!

they do bounce slightly on each other when spawing, prob have to check the collision presets

but thank you so much man!!!

[lofty rapids]

i think you can actually fix that in the spawn node

where it says always spawn ignore collision

thats what it's probably doing

try, try to adjust position but always spawn

and they will group hopefully

might work, might be shitty idk

[lofty rapids]

i would probably set a value on the widget, and use the widgets click event in the widget bp, when you spawn set the value on the specific widget, and when you do the event on the widget just get that variable

it's one way to do it i think, you could then call a custom event with the proper inputs on your original bp

so it would look like loop -> create widget, set variable, in the widget click -> get variable -> call custom event

[charred granite]

ye that sorted it, legend

mvp

[hasty merlin]

how do i fix this? what do i need to call? inventory component is inside BP_FristPersonCharacter

[lofty rapids]

get component of class ? @hasty merlin

[hasty merlin]

doesnt seem to be that

[lofty rapids]

if you drag out from the return value

you don't see a get component ?

[hasty merlin]

like this?

[lofty rapids]

no thats not it, goto your character bp

and click on the component

at the top right is variable checked ?

[lofty rapids]

drag out of the return value here, and search for get inventory

it should be there

[hasty merlin]

ahh i ahve to cast to bp_firstpersoncahracter first then i can get the component then get variablearray

[lofty rapids]

oh yes that makes sense right

i missed that step lol

[hasty merlin]

i made it like that late last night when my brain was mush

[inland walrus]

Ah nice I get you, I actually thought of something like that but didn't know if it'd work with maybe putting the same set on each widget

[muted vigil]

which one is better for better performance, toggling widget with visibility or adding to viewport and removing it?

[hasty merlin]

so like, i know im messing something up but im not actually getting a difference in the spawn amount. what am i doing wrong?

[lofty rapids]

because the array element in the for each isn't a reference it's a copy

you have to set it back at that index

[lofty rapids]

if your doing that a lot with a widget, probably visibility is probably better because your not constructing deconstructing the stuff each time

[muted vigil]

it's like inventory UI, player will use this widget a lot but it needs to be changed every time when it is opened. i have created a manager to control all widgets, which creates all widgets when the level has been started. do you think it is logical?

i have developed the system based on visibility route

[storm solar]

Ok so i tracked down the issue.
Its not that the button remappings are being overwritten, its just that the name of the input is set to the first input in a slot.
How do I get what slot is being used from the current action/ button?

Check screen shot to see what I currently have

Thank you in advance for any tip or help

[spark steppe]

i guess you have to call something to update the body instance (which is the actual physics mesh of the sphere)

no idea if there's a method for it tho

[charred granite]

Hey everyone, I'm back with another issue ofc.. 😄 I believe its a setting or issue with the collision preset of my enemy AI or my character. When I try to kill my AI, the bullets sometimes get blocked by other enemy their collision sphere I believe, as shown in the picture. Which prevents me from shooting multiple AI sometimes.

In the enemy blueprint I did set a node to disable the collision for corpses on the floor, but it still seems to be causing issues somehow.. Or maybe it's the line trace collision not set up properly.

On the side note, I tried setting different point damages for when I hit the head and body but the collision sphere seems to mess it up, and I'll hit the collision sphere instead of the head or body. I tried changing the collision presets too but no succes...

Thanks for your help.

[balmy belfry]

So you want your trace line to only hit the skeletal mesh and ignores the capsule ? If so, you need to show us a screenshot of your line trace node so we can see what channel is used, then in your ennemy show use the collisions details from the capsule.

[unique bronze]

its a function is what updates it which runs every tick and is supposed to add to the Sphere Radius, the value increases but the radius remains the same

[spark steppe]

might be easier to just scale it with it's component scale

[flat coral]

I've got a function which has a name, but the name doesn't appear? You can see in the tooltip it's named CreateSlotSave but in the details and nodes, the name is empty

The wild part is that if I duplicate it, the duplicate function inherits that error?

And yes, I've restarted the editor

[faint pasture]

what happen if you give it a random name?

[faint pasture]

Spooky, I'd nuke it and remake

[flat coral]

Oh now THIS is funky. This is what happens if I try to reference that function in another class

[charred granite]

Correct, I've currently removed the specific point damages for headshot and bodyshots as it wouldnt work, but i'll show you a screenshot of my line trace set up.

I feel like the enemy collision sphere causes issues as it will sometimes block me or the other AI, and it will take damage instead of the actual mesh. Here a picture of my line trace, the last 2 pictures of the node are prob irrelevant as it's for the particle effect and sound.

[flat coral]

Check this shit out. Brand new function, lookin fine. But what happens if rename that input param like I want?

Somehow, having a single input named DisplayName causes the function itself to lose its display name?! It must be colliding with some invisible parameter that determines that

[balmy belfry]

Thanks for the screenshots, I can see that you use the camera channel for your line trace, but if you look, at your capsule the response to camera it is ‘block’, so your capsule stops the trace line.
I would suggest to simply change the collision preset to custom, then simply make the response to camera be ‘ignore’ then you should be good to go 😉

[distant grotto]

Is there a better way to do this, or is this good?

I want to set the enum based of whether the fall time reaches a certain threshold.

I feel like it might be possible with some sort of select node instead of two branches

[humble lynx]

Hey guys, If i could have some help on this id appreciate it! been trying to get this working for 4 days now. So i have a Widget BP it has a base image its just a simple circle with some color, then i made an arrow too both made in Figma, took those into UE5 added in a canvas panel then added in 2 images one for the base circle and one for the arrow i got the arrow spinning in a circle with mouse movement but controller on the other hand is not working well. For controller i overrided the On Analog Value Changed Function within the widget used a Get Analog Value out of Return made a vector 2D set that then passed it into a custom function. Now inside here i took the value used a break Vector 2D took the X&Y plugged them into an Atan2 (Radians) Converted that R2D added 360 then did % Float node using the returned value out of the add for the top pin and for the bottom pin i put in 360 then set the final angle and plugged that into a set render transform angle, target being the arrow Image. But all the arrow does is flip flop from 45 (Top RIght of the base Image) to 225 (Bottom Left of the base image) Also the pivot point of the Arrow IMG is Y=1 X=.5 that makes it so the arrow rotates around the center of the base image. okay i can get some images but if you ever have played mass effect or something with a dialouge wheel thats what i'm trying to make so i'm making a radial menu with choices to choose from for npcs now my arrow is gonna rotate 360 degrees around a center point these pictures should help visualize what i mean:

[charred granite]

Thank you, will give it a try now. Also, maybe a bit of a "dumb" question but I noticed that there are 2 sections for collision presets, do I change it in the top one (the character mesh)?

[charred granite]

I changed it but my line trace still doesnt seem accurate, I can shoot next to the mesh and the collision sphere will still pick it up as a hit and count damage to the enemy

really been havin a hard time with collision presets, clueless. Ill keep digging

[visual crest]

Is it possible using blueprints to get the color of an object under the mouse courser?

[faint pasture]

thats a bingo i think

[faint pasture]

define color of the object

Maybe maybe possible, pretty hard to do I'd think

"Color of the object" is a thing very late in the rendering path

You probably need to go through a render target and post process material

[visual crest]

I want to make a UI color wheel

[faint pasture]

and color pick from the render?

[visual crest]

so I need to get the current widgets color and save it

[faint pasture]

you need to do the same math in your code as the material does

that's infinitely easier

You presumably have some math somewhere that goes from position to color, in a material probably? Do that same thing in the code

[visual crest]

ok so its not just as easy as haveing an image and hovering a mouse over it lol. No I have no math or any thing yet Just a color wheel as an image lol

So where do I start?

[faint pasture]

basically anything that involves data going from the gpu to the cpu can be a right bastard

right click in BP and type get pixel color, what are your options?

turn off context sensitive

[faint pasture]

That's probably the best tree to bark up

[visual crest]

ok any tut or hints? Thanks for the help BTW 🙂

Never even knew about this node

[faint pasture]

I'd start by figure out what it wants for Image and in what format

figure out some way to plug your color wheel image into Image

[visual crest]

ok

[visual crest]

I could not figure out what goes into that image so I asked chat gpt and it said it wont work for what I want and it said the only pure blueprint option is to convert to HSV to RGB and gave me this function.
Input: UV (0–1 range)
→ UVOffset = UV – (0.5, 0.5)
→ HueRadians = Atan2(Y, X)
→ Hue = HueRadians / (2π) + 0.5
→ Saturation = Clamp(Length(UVOffset)2, 0, 1)
→ Value = 1.0
→ HSVtoRGB(Hue360, Sat, Value, A=1)
→ Output: RGBColor (LinearColor)

Before I even try to make it I need your opinion on wither or not this will work GPT likes to tell lies! And I have no desire to spend hours making BS that don't work

[hardy merlin]

In the editor, how can I determine the distance between two actors? Not through blueprint, but with a tool.

[inland walrus]

Apologies on the delay, just got round to trying it but still the same issue

[blissful grail]

There is a measuring tool you can use in the non-perspective view modes. So switch to top down view or w/e and then measure. I don't know why it isn't usable in perspective mode.

[hardy merlin]

Yeah, really wish it worked in perspective mode

[lean flax]

Has anyone here done some profiling in regards to the performance of events vs functions in BPs, or have some insight to this matter? Are functions generally faster than events?

You're in BP - it legitimately doesn't matter.

The main differences between an event and a function in BP is that functions can have return values and they cannot have latent actions.

Events cannot have return values but they can have latent actions

I wouldn't think there is actually a measurable difference between the two however (perf wise).

in the main blueprint window where u add ur meshes and such
is it possible to parent a skeletal mesh to another skeletal mesh's bone?

I have a question about saving data, im trying to save an inventory component's sots that are apart of a crafting bench, the problem is how do i tell the bench at spawn to find the right data, in other terms if i try storing an id, the id for the bench will be destroyed on end play but not in the save game, so all of a sudden we have an id thats just sitting there. I thought about getting the bench location and hashing it which would work because the location remains consistent, so i would be able to use the location has to look up an id. Im not sure how to approach this, but at the end of the day the main issue is how does the bench know which data to load

[faint pasture]

yes

attach at socket or bone

[harsh blade]

thats the thing, its not letting me do that in the blueprint area
it lets me do it outside of it just not inside

wait thats for things in the world I need for UI 😦

[visual crest]

Thanks though.. Is it posible to make it capture UI?

[full badge]

Yea I need to make a color wheel for my character creation

I can't belive there is not a built in widget

Can some one tell me what I am doing wrong? The print string should be returning 0 to 1 but it giving 1 to 2

[visual crest]

Wow thank you!

it's very simple tho

you can just promote the return value to a variable and use it
