blueprint

[spark steppe]

you call it once on begin play and that's it?

[gentle urchin]

^^^^

Ding ding

Perhaps :p

[spark steppe]

how is that supposed to work then?

[heady saffron]

i know that would only be called once, but it isnt being called at all

[gentle urchin]

It is

Just not how you expect it to it sounds like

Keypress most likely happens after beginplay

Unless keypress spawns the actor in question

Which i doubt

[spark steppe]

also it feels like you are making it more complex than it should be

[heady saffron]

Ah u were right... I just wanted to test it on beginplay... didn't think it would actually not work at all with it lol

[spark steppe]

you can probably attach the camera to the socket permanently

[heady saffron]

I have it on tick now btw

[spark steppe]

and only set the relative rotation when the state of the bool changes

[heady saffron]

Thats what i did ben

If false it remains to the camera socket, if true i change the rotation

[gentle urchin]

If this is something that happens when an event is executed

Surely it should be evwnt driven

Instead of tick (or beginplay)

[spark steppe]

doing it onTick isn't the solution either way

[heady saffron]

what do i do it on then>?

[spark steppe]

just like i wrote before

attach the camera to the socket in your actor blueprint

and only change relative rotation when sliding starts or stops

[heady saffron]

so what r u telling me to change from here?

the code is jumbled up and some stuff isn't supposed to be there, but that was my original base... how would I incorporate a change without referencing on beginplay or tick?

[spark steppe]

select it all, then hit the delete key

actually i can't give you really an advice

because that BP doesn't really explain well what you actually want to do

the "logic" is a bit messy

[heady saffron]

So basically, its a 1st person shooter, when u aim down sight, it has the camera stuff set which is all good... I want to make it when you slide, the camera remains upright because when u slide right now, your entire screen is 90 degrees

[spark steppe]

so all you want to do is change the rotation of the camera?

[heady saffron]

when sliding, yes

[spark steppe]

i would add a rotator variable to the BP then, which you set according to the mode

and onTick you can rinterp to that target value

so you get smooth camera rotation

[keen hedge]

Since components cannot contain components, and child actor components are frowned upon ™️ (and child actor variables cannot be edited per instance from the editor anyway), is there a way to maintain composability of actors/components rather than using attach actor and proxy variables or manually creating child blueprint classes for each variant? Is there a book/course/guide on architecture of actors/components and general composability of things?

[spark steppe]

but trinigio1, at this point, keep what works for you

you may refactor that on your own later

[heady saffron]

@spark steppe Yeah I have it the same way as before and it works, im just typing in the position instead of a set rotation value... the smoothest way would be to have the rotator variable as u said, but if it can constantly keep track of the player's rotation.

[spark steppe]

yea you still have to use some bool check either ways

as you don't want to force a new rotation all the time

so keep it for now

[heady saffron]

yeah it works 100% rn, i just did what i said above, I just need to calculate the rotation needed on when it keeps track of player rotation + whatever amount needed for accuracy

[spark steppe]

but let's talk about another thing....

[odd ember]

not really no. tbh it just seems like you're trying to force the engine to work with the workflow you want rather working with the engine. if you want a bunch of customizable items it'd be better have them as data blueprints, or have the data injected through a data table rather than tweaking it in editor

[spark steppe]

that rotation stuff is on your player character blueprint?

[heady saffron]

no

[spark steppe]

on what then?

[heady saffron]

the ADS system on my actor blueprint

[spark steppe]

ADS system?

[heady saffron]

ADS means aim down sight, which means scoping in

so I have a separate camera for that when the player scopes in

[spark steppe]

and that's a component which is on your player character?

[heady saffron]

nope

[spark steppe]

on the weapon?

[heady saffron]

I have a socket on the player which it uses to connect to

yes

[spark steppe]

your way of getting the player is a bit "hacky", are you planning to add multiplayer support?

because that will be a problem then

[heady saffron]

yeah

oh u mean with the get player character?

[spark steppe]

yes

[heady saffron]

yeah replication and stuff was a pain at first lol

[spark steppe]

you should probably store a reference to the actor which holds the weapon on the weapon

so you also don't have to cast all the time

[heady saffron]

will do that

[restive token]

I have map variable where the Keys are integers.

I want to cycle through the variables in the map variable until I find one where they key (integer) equals something.

How do I do it?

[gentle urchin]

Is there anything to cycle? Cant you just find?

[restive token]

it looks like this

"find" searches the ammo, not the integer

[gentle urchin]

Thats enum key, and integer value

[restive token]

yes

it's a map

[gentle urchin]

Not what you said above^^

[restive token]

it's what I said, no? It's a map, where the key = integer

maybe I'm confused

[gentle urchin]

Key = enum

Value = integer

[restive token]

aaah ok ok

thank you 🙂

So if I have it like this, how do I find the next value in the map that equals something

[gentle urchin]

Not easily done

[restive token]

I made one function that works in editor but it breaks in packaging

[gentle urchin]

They're afaik ment for quick lookups and whatnots, not for iterating through, and especially not reliably in order

[restive token]

I see

thank you!

[gentle urchin]

Sounds like an Array is better tbh

But

You can always get keys and values, and go that way in bp

Get values , find 0 -> should return first index with this value

@restive token

So you basically convert them to arrays 😅

[graceful forum]

Bump, still couldn't figure out if I don't get the trace behavior or I'm doing something wrong

[remote glacier]

Does anyone know how I can fix this?

Driving me crazy now

[icy dragon]

A bit too blurry, but try refreshing the nodes

Or try creating the Is Sprinting node again

[remote glacier]

@icy dragon done both of that

Still get the same issue 😩

[wicked osprey]

Guys, I have two functions that trigger on pre construct in design time. And there's a cast happening every time. Will this script affect the game and clog up memory?

[lusty shard]

How do I store the Landscape as a variable? I can't "get reference to landscape" like I could in the level bp event graph. Trying to store landscape as a variable so a trace can ignore landscape.

[odd ember]

don't think that's exposed in BP

[willow aspen]

hi how do i place a simple number like "5" on the blueprint?

so i can do a multiplication with it

[lusty shard]

Add a Text Render component

[willow aspen]

text? are you sure?

[lusty shard]

no lol

not sure

[willow aspen]

i mean i want to do math with it not show it somewhere as a text

[lusty shard]

you want an integer variable, compile, then set its default value to 5.

[icy dragon]

Integer variable.

[willow aspen]

in the material editor i want to multiply a texture with "-1"

to invert it

[odd ember]

the material editor isn't blueprint

ask in #graphics

[willow aspen]

oh ok

[tawdry mural]

1-x node inverts

[willow aspen]

thank you!

[lusty shard]

so no way to store landscape as a variable in the player?

[odd ember]

.

[tawdry mural]

you can get reference in level blueprint

so its possible

[odd ember]

they're asking to store it as a variable. I'm also uncertain of what you can actually do with the landscape actor in BP

it's not as easy as "WELL IT'S THERE"

[gentle urchin]

Cant you just filter or adjust the trace anyways?

Or adjust the collision response

Not sure why you'd wanna go below the landscape tho

Or through it for that matter

[odd ember]

I can't remember if landscape has collision exposed

[lusty shard]

screenshot coming

[gentle urchin]

Fair enough

[odd ember]

doesn't seem the landscape is getting hit to be fair?

[thin panther]

If you want a sphere arpund the player why not add a sohere collider

[lusty shard]

refer to print string on top left

I need to trace break hit result for managing instanced meshes

[gentle urchin]

Multitrace

[odd ember]

I am. it doesn't seem to hit the landscape?

[gentle urchin]

Filter result

[lusty shard]

sorry

seems it is hitting the rock which is ideal haha, but I am targeting bushes atm which are handled a bit differently.

[odd ember]

fair, that is interesting too. I don't know if that component is accessible

[gentle urchin]

I would think isms were easier but dunno

Not sure what heightfieldcollisioncomp is

[odd ember]

probably an optimized collision component for landscapes

[proper wyvern]

does anyone know if this is still recommended for online turned based games? https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Online/TurnBased/

Not much info online

[gentle urchin]

Is this perhaps what i saw in Stack'O'Bot aswell i wonder... some rocks which i could step on and collide with, which were not visible in collision view...

[lusty shard]

Not too sure either honestly. I did some retopo when doing the terrain sculpting, then did a resample, which might have made that collision for the landscape :/

did the resample because at some point physics objects (trees when chopped and falling) would fall through the terrain.

basically updates collision as far as I know for landscape

[glass stump]

I've set my game to change camera by pressing a button but for some reason it doesn't change to the camera view and instead just goes to where I happened to last be looking in the viewport. Any ideas why?

I'm not even sure how it could make the connection lmao. I'm not piloting it....

[trim marsh]

Hello guys , need help about it , im building an array that save a variable(var) , everytime that i push a button , so the array actually is saving the variables(var) , but when i create another var , it takes the last one added and forget the previous. im needing like never forget a reference when its add a new one var.

[wicked osprey]

Guys, I have two functions that trigger on pre construct in design time. And there's a cast happening every time. Will this script affect the game and clog up memory?

[dawn gazelle]

Your issue is stemming from the way you are pulling the print string value. The print string will only ever grab the last element of the array that the loop above accessed. This is why it's bad to pull pins across execution paths.

If you want all the values from the array displayed on tick, put a foreach loop on tick with your array fed in and print off of the loop body.
Also the GET there for the array is completely unnecessary. Use the "Array Element" pin on the for each loop and you can connect it to your "Break STR_RouletteItems" node.

[untold dust]

Hello everyone

I have a newbie issue... something probaly stupid.... I create a chat system, in game if I hit Return the Editable textbox got focus and I can type text and if I hit Return the text is sent to the slot. Editable textbox lost focus and that what I want, but each time I need to click on the 3D Game viewport to be able to capture the keyboard event. it's look like the gameview port lost it focus. I changed the input mode to UI or Game does't change anything so I'm lost lol

it's something to do I think with the mouse capture

[trim marsh]

Thx so much

https://tenor.com/view/baby-yoda-i-love-you-heartbeat-heart-love-gif-15951417

[graceful forum]

Bump with the visualization of my problem

[desert juniper]

There's a node to set focus to a specific UI element

[untold dust]

I use the set focus and I chose the widget control but does't seem to change anything....

this work perfecly

but when the message is sent the event is lost, I need to click on the game viewport to make it work again

[timid orbit]

Hello, I’m currently working on a blueprint project where multiple people worked on the same blueprint. We then came across the problem where we cannot merge the conflicts and have to choose between one version and discard the other. How do you people solve this kind of situation ? Is there any merge tool for this ?

[earnest tangle]

I think there is some kind of BP merge tool in UE if you use UE's builtin source control features, but I've never used that so not sure how well/if it works

[rancid quartz]

Hello, I have a question about LaunchCharacter.

The speed of the effect of LaunchCharacter seems to be different on Android versus PC. I'm wondering if anyone knows why that may be?

Any advice would be appreciated.

Cheers.

[odd ember]

framerate?

[timid orbit]

I think there's only a Blueprint Diff tool to visualize the differences between the depot and the local revision

[earnest tangle]

That may be the case yeah

This is one of the reasons to use C++

[timid orbit]

since we worked on different branches and on the same blueprint, we tried to merge the conflicts but no chance so far

[gentle urchin]

If it doesnt work then you're left with manual merge

Which can be a pain if there's a lot of changes

[timid orbit]

It'll be a huge pain in the *** yea lol

[lusty shard]

screenshots please?

[timid orbit]

I guess that's it, thanks for answering anyway 🥴

[lusty shard]

Any idea what are the things that make event graphs run slower or less smooth? Really noticeable when dragging execution wires. It happens in all bp event graphs, not just the ones with lots of nodes. Even when all but one event graph is open, still laggy responsiveness.

[manic vessel]

Hi everyone. 👋 .. Im having some brain fog and need help. I Have a magazine with a ammo count and a max ammo limit. The Magazine is being spawned from a ammo bag and that also has its own Ammo values for bullet types . Im trying to set the ammo in the Magazine to the maximum limit as long as there is enough in the ammo bag and remove the same amount from the Ammo bag. which is what I have done here . But I dont know how to handle this if there is less EG: 5 rounds in the bag being set to the mag . here is my BP.

[earnest tangle]

Set ammo in magazine to min(magazine capacity, available ammo)

then deduct the amount in the magazine from available ammo

[manic vessel]

ok I think I got it🤔 . if there is not enough to to set max ammo. then just set the magazine ammo to what ever is in the bag directly? ,

[earnest tangle]

the Min node will return the smallest value from the ones you give it

so if the available ammo is less than mag capacity, it would use that value, and vice versa

[manic vessel]

Thats new trick for me. 🙂

[earnest tangle]

you can do the same with some branches but using the Min (and Max) nodes is often a bit more convenient :)

[gentle urchin]

Wouldnt it be easier with some map for this?

key = type an value = amount ?

[manic vessel]

What is the most elegant is what Im after

[gentle urchin]

I would think the ammo bag would have a TMap of the ammo

[earnest tangle]

Yeah the bigger picture really depends on how everything else works

[manic vessel]

I might have different weapons that use the same bullets types but have different capacity's thought

[gusty shuttle]

Quick question: I'm getting this error, however it seems to be doing the job but the error keeps popping up

[gentle urchin]

Weapon would in that case have a variable for its capacity

so ammo bag or weapon would be maxed by the magazine capacity

[gentle urchin]

magazine cap either being part of the weapon, the bag or a separate actor...

[manic vessel]

This is just the mag. the weapon pulles the ammo from the mag on insert

[gentle urchin]

AmmoBag == mag?

[manic vessel]

I think Zomg has the right approach Im just to stupid to visualise it yet

[gentle urchin]

Yeah it sounds like a good approach to it

[gusty shuttle]

nvm, solved my problem, an action mapping's name was wrong hehe

[graceful forum]

Bump

[rancid quartz]

Thanks for your response. I don't see how it could be tied to the framerate based on my logic here though.

[manic vessel]

Im a bit lost 😦

this way?

[manic vessel]

Like this?

[earnest tangle]

Yeah

[manic vessel]

🆒 Thank you 👍

[odd ember]

it doesn't have to be tied to your logic, it may be internal in how the launch character node is handled

[rancid quartz]

I see what you mean. Thanks. I guess I'll have to dig into the engine code and see if LaunchCharacter is somehow frame rate dependant.

[hollow steeple]

Hello everyone, i'm trying to get "draggable" doors (ie - Amnesia/Phasmophobia Style) I tried to follow a youtube tutorial but ran into several problems like the door moving too fast and getting stuck when reversed. I would also like to know if it would be possible to add a lock & key system to this type of door also. Thanks in advance!

[gentle urchin]

On button down -> Add Axis value to door clamped at min/max angle

[hollow steeple]

Sorry I'm extremely new to unreal and still learning the ins and outs of the blueprint system, would it be possible to provide a visual reference?

[random delta]

Im kind of stuck with a turning issue on a ray cast physics based vehicle controller.
When I am adding force, it works fine but when the car turns, it refuses adding force in that direction. rather its like it is stuck on one axis but really weird.
Im not entirely sure what the issue is but I think i might need to turn the force direction with the vehicle body somehow? Not entirely sure how tho.

this is my current setup.

the vehicle body is parented to a capsule

[dawn gazelle]

You want to take the forward vector and multiply it by the axis value by a certain amount.
Output force = (AxisInput*ScaleAmount) * ForwardVector

[random delta]

Do i get that by something along the lines of Get VehicleBody rotation?

[dawn gazelle]

You already have the body forward vector.

Right now you're doing:
Output Force = (AxisValue * (ForwardVector * V(10000,0,0)))

[random delta]

im not sure if i am missing something but its the same result

does it work for you?

maybe my setup is just scuffed. ill try deleting something

this one works for now!

dunno why the axis value messes it up in that way but shrug

[dawn gazelle]

Looks like you maybe are using an int * vector rather than float * vector?

[random delta]

absolutely

that an issue?

[dawn gazelle]

Yes and no. If you don't care about the axis value at all, no.
If you want the axis value to work, then it needs to be a float, then (axis value * scalevalue) * forward vector should work.

[vital aspen]

Guys, thanks again for what help you could give. I think I'm just to give up on it. I have had inventory issues in the pass and never could get anything to work. Wanted to say thank you to everyone help has help or tried to help.

[random delta]

i dont know why it works now and not before but your setup works. thanks buddy

[trim matrix]

Hey guys so I've been trying to input the aim down sights animation from the starter pack but when I run the gun is attached to my hand and when I click it makes my character go into the t pose and not move after?

[zealous moth]

do while loops ever NOT return infinite errors....

[bleak swift]

Why do I get this error?

Error: DisableInput can only be specified on a Pawn for its Controller

[trim matrix]

Wouldn't u need 2, one for target and one for player controller or just 1 for target but I'm not exactly sure since I've just started unreal

Nvm I think I'm just being stupid

[fair magnet]

Why you're using "GetPlayerController" tho?

[mellow folio]

You’re probably calling this on something that is not a pawn, or is a pawn of some other player

[fair magnet]

Try Get Controller instead

[mellow folio]

Why would that matter

[fair magnet]

Imagine you're on pawn2 trying to get player controller 0

You'd try disabling input for something you don't own

[bleak swift]

It's a character

[fair magnet]

[bleak swift]

They aren't the same reference

[fair magnet]

Wdym

[bleak swift]

Get Controller is a Controller Object but Player Controller is of course for a Player Controller object

[thin panther]

in a multiplayer game, if you always get the first player controller that aint good

[fair magnet]

Are you New to unreal by any Chance?

[bleak swift]

No?

[fair magnet]

You're able to cast

From Controller to player controller

If you even have to

[fair magnet]

Ye

[fair magnet]

I'd usually recommend getting away from anything sort of Get X from index anyway

[thin panther]

I mean it's fine in single player

aint ever gonna have a second player controller in single player

[fair magnet]

Sure... but why getting used to it? ^-^

[thin panther]

some people dont wanna make multiplayer games

[warm island]

sorry to interrupt you guys, i'm trying to set a vector value on my blackboard like this. in play it says the vector is invalid (any vector i try seems to be invalid when i try to pass it in like this).
any ideas on why i cant pass the vector in like that?

the key name is correct

[fair magnet]

getplayerpawn

[warm island]

? D:

[fair magnet]

Nah don't mind it

[fair magnet]

Atleast not if you don't care about Multiplayer

[warm island]

yeah i know. its just for a small project

is there anything i have to call before passing a vector? setting any other value type seems to work fine...

[fair magnet]

Try a print string to see if there's even a vector in the first place

[warm island]

it is, tried that already

i mean it is passing a vector

[fair magnet]

So?

What's the matter?

[warm island]

it is passing a vector like this, but the blackboard says its invalid

[thin panther]

have you actually put anything in the name variable

[fair magnet]

Well I need sleep c: I'm sure Mr.Tea is able to help u

[warm island]

aah

i didnt save lol

i'm so dumb. 🤦‍♂️ thats it. thank you

[thin panther]

made the exact same mistake many moons ago lmao

[fair magnet]

I can assure you... it won't be the last one

[warm island]

please no D:

[thin panther]

spent 2 hours tryina figure why something wouldnt work just to figure i was writing to the same index each time

so yeah, it will happen, forever

[fair magnet]

Spent 2 days "fixing" a function just to find out I never specified it's inputs

[thin panther]

that was basically what i did, i had a zone system, that fed its data to my HUD, but i never specified an index for the HUd, so they were all 0

[fair magnet]

Lmao

[thin panther]

i spent so long tryina fix my code, that i didnt realise it could be that i forgot a variable

[fair magnet]

I have a save system that takes savegame classes in the configuration.ini but I tried loading things I never added

Even better a short while after I failed loading it... know why ?
Because I tried loading Config instead of Configuration

[thin panther]

like the one above, i spent hours tryina figure out why my AI wouldn't move to the chosen location, just to find out i never actually told it what key to write to in the blackboard

oooooooooof

yeah that oen must have hurt

[fair magnet]

We should stop we might scare Aaru

[distant grotto]

how can i make an object move in the direction its facing?

so far ive only managed to get it to move in a direction regardless of hich way its facing

i can get it to make it move aong its x axis, and then once the object it rotates it does not change the direction its moving

[thin panther]

forward vector

[distant grotto]

so add to the X of the forard vector?

this doesnt ork so i guess ive got it wrong

[runic parrot]

Hi! i'm having a trouble with "Get hit under cursor by channel" hitting pass my UI.
Does anyone know how to make this also hit the UI so it doesn't hit the actors behind when the UI is open?

[distant grotto]

@thin panther ?

[thin panther]

the forward vector is the vector that points forwards

you dont need to break it

[vale pine]

More like this, I think

[thin panther]

ye

[vale pine]

Is it possible to lerp between 2 vectors without using Tick?
One or both of the vectors would be changing every frame (ActorA pos to ActorB pos).

[distant grotto]

Thanks

That as a dumb mistake on my part lol

[thin panther]

you could use a timeline

but if you need something to change every frame

that is a tick

[runic parrot]

In case anyone has the same problem, i just changed the trace from "visibility" to "Camera" and that did it.

[plain jay]

Has anyone had problems with using data tables as variables? when i use the "GetDataTableRow" node and then promote the DataTable to a variable It wont actually allow to expose the OutRows

for example

I can plug in a data table manually, but this makes it hard to expose to children blueprints

[thin panther]

well thats a wildcard, you cant promote that

[plain jay]

oh I dont want to promote the wildcard

[thin panther]

since a datatable will return a struct, but it doesn't know whihc struct, it cannot be promoted

you are trying to promote out row correct?

[plain jay]

oh haha no, just trying to promote the data table itself like it is in the screenshot. like when i promote the input data table it will only output the wildcard

[thin panther]

ah gotcha

[plain jay]

and I cant expose for params

[thin panther]

well since that can change, it doesn't know what type of data it will return, meaning you cannot perform an operation on it

[plain jay]

is there any way to give it a struct that cant change?

[thin panther]

if i have a struct, that has 2 integers and a string, but another one with 2 textures and an actor, there is no way for the code to know whihc one it will return, unless you specify an exact table

[thin panther]

then that would defeat the point of having variable tables

as you could just put it all in one and filter the results

you have variables to define data that can you dont know, and can change,

if it can't change then there is no point in having a variable

[plain jay]

ah ok, Im making a custom layered clothing system, and I have a data table for each clothing type, ie, gloves, shirt, jacket, etc. but they are all sharing the same struct. would it be easier to just combine all clothing into a single data table?

[thin panther]

probably, then you could have an enum to filter the results by

so if we are in the gloves bp, you could pass in gloves, and that would say, hey filter these results so we only work with gloves

would be a lot more ground work

of course you could also just change that specific function for each child

if they all use the same struct, then you could return a row struct, then just override the function in each child to change the data table

[plain jay]

ah ok, makes sense. that was my original thought but i felt like it would get messy.

I See the filter array but that only allows for actor object references. is there another way to filter array objects such as skeletal meshes?

i may just be missing the node name

[thin panther]

or you could have all of them in the armor master so you have a function to get each data type, then just change whihc one based on the clothing

lots of ways to do it

not really any right one

[plain jay]

or filter enums actually

contains?

[thin panther]

the filtering may have to be done manaully, im not sure if there is a node for that as i am tired lol

[plain jay]

no worries, thank you for the advice!

[thin panther]

although if it is just on data table row by name you shouldnt have to do that

even if you collate into one giant table

cause for each clothing you can just say, get the row called Gloves_SuperCool

[plain jay]

i do have a clothing type enum already present in the data table

i could just filter via that

[thin panther]

and then you only get the data from that

so if you had the row name as a variable, then in each child class specify the armor you want to retrieve you can skip all the filtering stuff

and from there you can do either way, either in 1 giant table, or specify individually

[plain jay]

I sometimes forget that you can override functions in the child lol

[thin panther]

have you tried plugging a row name and setting a data table in the variable

[plain jay]

that will actually work just fine

[thin panther]

cause that may fix the wildcard actually

[plain jay]

oh yea tried that but same thing

[thin panther]

ah

then ye do either

1 giant table might be easier, but both would work

cause in both methods, you would still get the data for only GLove_SuperCool, in BP_Glove_SuperCool

but idk, try which ever method works best for you

at the end of the day whatever works best with your workflow

[waxen knot]

hay so im making a third person shooter game and im making the ammo system and I almost have it but I want to make a widget that displays how much ammo you have but I dont know how to set the text to my ammo float

I was thinking I could cast to my player base and then use the ammo float like that but I can get to my text part

[thin panther]

you have the easy way and the slightly less easy way, you can A, create a binding on the text, that gets the ammo from your player and plugs it into the return value, or you can make an event to directly set that text every time you fire

A is less performant, but easy for beginners, B is a little bit harder, but saves on a lot of performance

anyway that said it is 1:30 am so it is bedtime for me

[waxen knot]

how would I bind it

[thin panther]

If you click on your text in the widget designer, there is an option to create binding

[waxen knot]

ok I see it thanks

[thin panther]

No problem :)

[waxen knot]

I think I messed it up

I did this

and got this

[thin panther]

You havent told it what to look at, youve told it a player character but not which one

Replace that with getplayer character

[waxen knot]

it wont connect

you ment replace target right

[thin panther]

Yes

[waxen knot]

ya it wont connect

does it work for 4.27

[thin panther]

Cast to your player then

[waxen knot]

then what is the object I have tried every thing

[thin panther]

Get player character

[waxen knot]

nope

[thin panther]

See the exev pins

Exec

They arent connected ti anything

[waxen knot]

what do I conect them to an event tick

[thin panther]

I reccomend you look at a basic unreal thing

Check the pins in #ue4-general

But no, you connect it inbetween the input and return value

[waxen knot]

ya I just got that

thanks

[thin panther]

Np

If im looping to create widgets in a box

how would I do On click for a button im creating

This isnt my long term solution but Im curious

Thinking I cant call on click / press for something that does not exist yet

Or maybe I add that function on click in the child that im creating

I think I just answered my own question

is this correct 😛

[thin panther]

Yeah

In the child widget make your onclick

[austere fiber]

So I currently have my jump set up like this. Which involves launching the player Up. Then I use a gravity scale to adjust jump height. So releasing the jump button will prevent the player from reaching max jump height, whilst holding it will give them max jump height. This method works. but brings up two main issues.

First is if the release is close to the apex of the jump, the player will fall faster then if they just held the button due to the temporary gravity scale change.

The 2nd is that the temporary gravity change can affect the double jump if double jump is pressed in the same time.

How would I fix these two bugs, or alternatively. Is there a better method to get the player to have a variable jump height based on time held.

[dawn gazelle]

You're getting there, yeah. You have two options:

1. Provide some additional expose on spawn variables and code so each of the InventorySlot widgets can manage themselves - so their own button presses will do their own thing.
2. You can create an event dispatcher within the InventorySlot widget and when you press your button, you call that dispatcher. When creating the widgets, you can then bind to that event dispatcher from the reference you receive when creating them. For this to work with any sort of meaning you will need to pass data through the event dispatcher so you know what button was pressed, or know what action to take when any specific button is pressed.

[tranquil abyss]

I crated a integer exposed in the slot

and used that to do it

like I did with my inventory

seems to work

And Im using a map on my character from in to object actor ref for the abilities

integer gets the ability and it works

😄

im learning

I porb still need to use an event dispatch at some point just to learn about it

I'm trying to do a multi sphere trace to see which bones are inside my trace. When the other player is in range of the radius from the start point, I can get all the bones as a different hit result. When the other player gets out of the range I only get a single result with the closest bone, although it's still in between the start-end points. Am I doing something wrong? Shouldn't I get all the bones whetherless the player is in radius range or not if it's in between the start and end points?

[main lake]

nope I'm just trying to get the value of my struct (Speed Level 1, Speed Level 2, Speed Level 3)

[dawn gazelle]

Then drag off from these pins.

[main lake]

Nope I need to drag the right value depending of the item selected in the Struct

[thick orchid]

Anyone ever use an animation and it adds a heap of velocity?

[thin panther]

Why not have 1 speed value that you update when needes

[main lake]

It's already the case but instead of hardcoding the values, I want to use my struct with those 3 floats to swtich between my default speed, speed level 1 and speed level 2

[thin panther]

Then use a select node

[thick orchid]

ah ConstrainAnimRootMotionVelocity

[thin panther]

Use the enum in select, and that will let you plug in a value for each thing in the enum @main lake

[main lake]

but If I'm not mistaken, the select doesn't know what value is selected, right ?

[thin panther]

The select uses an enum and picks a value based off of whats the enun currently is

[main lake]

so the struct saves the last selected option ?

[thin panther]

Maybe change that byte to an enum

I mean if you tell it to

[main lake]

At first I used an enum but couldn't have a pair of name and a float value (as it's indexed based)

[thin panther]

Use a select with the byte then

[marble echo]

i think i'm missing something super basic here and my brains not working, but this spits out the entire sheet (i imagine its the 'for each loop'), how would I get it to just spit out a specified index?

So pick random direction

GetActorLoc + (Direction * distance) = TargetLocation

Either Interp and calculate velocity to use with the anim bp

Or apply inputs according to direction

😂 overEngineering much?^^

I'd VInterpConst on tick for consistency , but timeline could also work if you adjust playrate according to distance

Usikg a bool to gate it, reset by a timer/delay so it doesnt always move

is it considered bad to have too many structs and enums defined?

i have about 30

[maiden wadi]

Add a zero to that and we can start talking.

[random plaza]

good to know

i use them to pack more data into save files efficiently, it takes less time to code, even with blueprints

[gentle urchin]

As long as they make sense theres no limit 😄

[maiden wadi]

Realistically, there's no downside to having a bunch of structs or enums. They're just containers basically. They're nearly nothing. Reuse them if you can. But I wouldn't fret over making a new one. This is even more important in C++. Some actual classes even define their own internal use structs in the same files just to organize data better.

[restive token]

Is there a way to know when the user has come back from alt-tabbing away?

When the UE4 window has focus again

Normally, once you alt tab back, UE4 requires you to click inside the window to give focus to UE4. Alt-tab is not enough.

But my game doesnt have a cursor ever, so people don't realize they have to do that

There we go

[sharp sable]

What block in a blueprint would I use to check if the bottom side of my character is colliding with an object that has collision? Trying to use this for a jump when learning blueprints but I can't find something that could tell me which block to use. Basically, I want upon the input of W, to then check if character is colliding on the bottom (aka the floor, but since it's a platformer it can't be "colliding with (object)") and if it is colliding then to allow a jump and if not then it doesn't jump

I just need the part to find out if there is collision

[lunar nest]

This should do the trick

[sharp sable]

If I use that and then use the false to mean the player can jump, then wouldn't it allow the player to jump while they're moving up in the Z-axis? Since moving upward isn't falling, unless Is Falling accounts for up and down movements on Z-axis

[lunar nest]

It accounts for both

[sharp sable]

Oh okay thank you I should have just tested that myself before making the assumption about the word falling

[lunar nest]

The name is misleading, though

However, you don't need to do any manual checking yourself - the character class (and the character movement component) already come with all the functions needed for, well, a basic character movement.

[vital aspen]

for those of you have been helping. I'm getting there

The Issue is "Find Stack." It doesn't see an stack in the inventory.

[random plaza]

one more question, in UMG is it possible to make any image streached the same way buttons are? i have a button that i want to use as a background and ive just been using buttons with hit testing off

[thin panther]

You can stretch an image yes

[sharp sable]

I set this up based on your suggestion and it works for the initial jump but the second jump never happens, is the jump function only applicable during collision or something?

[random plaza]

so where can i change it an image is stretched or not?

[thin panther]

You just stretch it out

[random plaza]

i mean, like keeping only the corners unstretched and streaching the sides and middle

[thin panther]

Send a ss to show what you mean, im having a hard time visualising

[lunar nest]

There's a few things you would want to change. First of all, UE4 already has functionality for a multi-jump. Click on Class Defaults and search for "Jump Max Count". Increasing that value and getting rid of the second branch node and the decrement node should solve your problem.

Furthermore, if you want the count the number of somethings (i.e. the max number of jumps), use a variable of type int, never type float

[maiden wadi]

@random plaza You're looking for DrawAs Box, and setting margins up. The effect is called a 9-Slice

[random plaza]

ok, well i appreciate it

[maiden wadi]

Usually most 9 slice images need to be pretty small, as in 128 px or smaller. Most times a 0.5 margin on every side is fine. Sometimes you need to bump that down to like 0.25, rare though.

[sharp sable]

Thank you for that I didn't know it already had a built in multi jump, turns out all I needed was the input event > jump function

I'll keep using int in mind for the future thanks

Considering I did that in such a dumb way I assume there's a better way to do this too isn't there?

[lunar nest]

I can scarcely imagine a scenario where you'd want to use absolute world directions for input

The direction depends on what type of game you're creating. For first person games, using a GetActorForwardVector node should be enough. (The same works for tank controls, i.e. old school Resident Evil style)

[whole dune]

so i have an object moving along a spline and i want to add another one with offset… can someone help me?

[mental robin]

This just looks weird and wrong. Updating the time doesn't actually change it for the timer unless I run through the timer again to set it. Does this create two instances firing off looping or....

[balmy vessel]

hey guys, ive been working on a bit of a refactor and saw this old system I had. Now i'll preface this with, it does work it just doesn't look right, it looks v janky. Was wondering if there was another way to do it? I had to do it this way because the Convert To World Location node didnt work, maybe i was using it wrong?

as a side note, this is on a non player controller script, when i do a similar thing on the player controller script, get hid result under cursor by channel works, but when on any blueprint that isnt the PC one it doesnt?

[maiden wadi]

Chances are you are capturing cursor on mouse down. Controller cannot do hit results under cursor in that condition.

[balmy vessel]

i do have some functionality in the On Mouse Button Down function, that calls every frame the mouse button is down doesnt it?

[maiden wadi]

That should only run when the mouse first presses.

[balmy vessel]

hm, basically my intended behavior is to click a button, generate an item based on which button is pressed and then while its being dragged the item follows the cursor (which then snaps to grid tiles)

and it works, but the way I have it setup atm is messy and also, I have a feature where the user can pick the objects back up off the grid and drag it around again, so i have very similar but slightly different drag functions for each start point and i cant combine them

i first wrote this a couple months back when i was still new to unreal so i probably did something wrong but cant identify what it is

[maiden wadi]

As in the user presses mouse down on the button and never lets up and drags out onto the game sort of motion?

[balmy vessel]

ye

i have a custom drag operation that calls back to an event on the asset list item when a drag is detected

[maiden wadi]

I'd really consider creating a DragDropOperation child for that. There is an overridable event in the class for Dragged that runs every time the mouse motion is detected. All you need to do is call detect drag if pressed on the button, and override OnDragDetected, create the operation subclass, pass whatever it needs to know to it and it can handle itself until it's finished.

[tired granite]

guys im having an issue , i am creating a footballish type of game and when i attach the ball to the player (socket from the mesh) and then detach it (reneabling collision and physics) it looses its collision and just sits there anyone have any idea why this is happening?

[balmy vessel]

yeah, ive done that

this links back to the first event i showed

[maiden wadi]

Ah, I forgot you don't have a C++ base so you have to call back to the widget to get world for the controller. Otherwise I'd say move that all into the operation object. But your function for getting world location is fine. Wouldn't bother messing with it if it works and there aren't side affects.

[balmy vessel]

well the issue comes from having 2 nearly identical versions of the drag functionality, one for when its dragged from assetlistitem and another from when the item is picked up

ideally id combine these so that when i change functionality, im only changing 1 function not 2

like, i tried to have a DragItem function on the player controller, and when the assetlistitem is dragged, it sets the drag target but lets the PC deal with moving it, but when i did that, when called from the widget, it wouldnt work with the get hit result node, and when called from the PC it didnt work with the deproject version

[hexed glade]

How would you go about letting an enemy know your character is about to attack? Do you use perception or an interface event (a bit unsure about the best way to target with the interface).

[tranquil abyss]

So I have a little menu of abilities that I can pull up with a button press,
I want to be able to still move around with WASD or stick while the menu is up but I want the scroll wheel to change the selection up and down for the (basically just a vertical box of buttons w/ text) and when I attack (Click or A button I guess) I dont swing I use that ability, I think I can handle that with a bool like Ability menu open

Tlde: I need to move the character still but Scroll to select ability and click triggers the selected

So I need a focus on the UI part somehow without changing the input mode completely

I would show code but im not home

😄

I do alrady have to pressing of the button firing the ability

[maiden wadi]

Sounds like you just need a Control Mode for Game And UI set. PC is easy. Just set focus to the widget. Consoles might be a little harder.

Fairly new to unreal and I'm trying to handle in-game widgets (general menu and a scoreboard). I'm able to call both while the other is constructed and I'm wondering if there was an override function I'm missing that is best practice to handle the issue of only wanting a single widget to be callable while the other is active. Is anyone familiar and able to point me in a direction to learn about the handling of this?

[trim matrix]

Can anyone tell me how to do first person footsteps WITHOUT a skeletal mesh or animations?

[maiden wadi]

As in you are wanting only one of them to be displayed at a time, or?

[maiden wadi]

Probably tick. Make a simple check that checks velocity. if > some amount, and last footstep play time > some time ago, play footstep and save last footstep play time

[low birch]

Yeah that's right. So Tab would be a scoreboard and Esc would be a in-game menu with options and such. Currently I can hold down both Tab and Esc and have both widgets display. I'm looking to have only one being able to display. Not sure If this is a Boolean, function override, or some sort of input disable. I'm not too sure. Just wondering if someone has an idea of best practice for me to sink some time into reading and figuring out.

[maiden wadi]

I do something similar, but my implementation is pretty advanced due to some viewport requirements I need. It's possible you could just make a single pointer to other menus as a UserWidget pointer. Make yourself an AHUD function that adds your fullscreen widgets to screen. If that pointer is valid, and that valid widget is in viewport, remove it, then add the new widget to screen. Then the last widget attempted to be added to screen is the only one that can be added. Allows your widgets to still be garbage collected after having not been accessed after some time. If you don't want them collected, you could change the single pointer into a TSet of UserWidget pointers and just iterate over them to remove them from viewport before adding a new one.

Unfortunately, UI is a very personal project oriented design thing so the framework for it is extremely sparse, so it's pretty much up to you to handle it how you need. Very strongly recommend using the AHUD class to manage pretty much all of your UI that isn't in a WidgetComponent.

[low birch]

Amazing, thank you Authaer. I appreciate your time in writing that! I'll look into this.

[maiden wadi]

If you enable input in your AHUD you can even put your keybindings there directly.

Hi i have problem attach glove to hand and how to make it follow the fingers

[sly relic]

You can add a Widget component to an Actor to show a widget in 3D space.

You can also use a Widget Interaction component to simulate a mouse to allow players to 'click' on buttons and stuff like that. A common example would be in VR where the player has a laser pointer-like thing and can aim at UI elements.
It lets you simulate mouse buttons so you don't really need to do anything different when designing the widget itself.

[dusk nymph]

where does save game slot saves in the client or the server ?

[dawn gazelle]

Depends if you're running the save operation while running on a client or on the server.

[maiden wadi]

Well that was easier than expected to make a floating pawn movement ignore game time dilation. O.o

[dusk nymph]

ok so for a multiplayer game i should run it on server event right ?

[dawn gazelle]

It being a multiplayer game doesn't give any indication if something should be saved on the server or the client. If it's something that should be saved server side, save it while running on the server. If it's something that should be saved on the client, save it while running on the client.

[maiden wadi]

Case. I use a savegame object for user's UI settings. You wouldn't want to save that on the server. Though I imagine you'd want to save the actual game's progress and state on the server and not on a client.

[dusk nymph]

ok it was a stupid question

[dawn gazelle]

No such thing as a stupid question.

[dusk nymph]

yes and things that i don't want the player to change like the player position should be saved on the server

[vital aspen]

It looks like I have it working. 1 question. when you add to an inventory. why would the 1st item add to it would show up on the last index and everything else would start at the top.

[dawn gazelle]

Sounds like you're using an array "ADD" node when you possibly mean to find an empty slot and populate that with the item instead.

[vital aspen]

I use the ADD node to setup the slots. Yes. and then in the inventory UI. it loads the slot widget

[wind void]

Hey is the Timeline node asyncronous? As in I can have a timeline loop forever without any issues?

[odd ember]

very few things are asynchronous

it's just another tick call

[charred flint]

Hi guys I currently use this screenshot background but I was wondering if its possible to make a cinematic view of the map in the background instead

[odd ember]

sure

it's just a map background

so you'll have to load in the appropriate assets and arrange them

[charred flint]

I am using this image canvas background currently in widget builder

[echo salmon]

Those nodes are suppose to bring the mesh down when player overlap the component . The time line values over 1 sec is 0t - 4.0 - 1t - 0.0 , i get button initial location at the begin play . What i dont understand is why we + the 4-0 float value with the initial z position ? Its because in the Actor blueprint we got local location and in the level we got world location ?

[odd ember]

I don't know what's going on here. this would set the location's z value to whatever "4-0" is

it's better to use a lerp in this case

[echo salmon]

The timeline spits the float values 4.0 to 0.0 over 1 second

[coral lance]

this problem isnt the right place to ask this but my player is spawning under my map even if I select to have the player spawn where the camera is or i put a player spawner actor

[distant grotto]

I cant seem to get vinterp to work, it doesnt interpolate at all, behaves no different to my setup without vinterp

[low birch]

Double check your gamemode has the default character set to your player character of choice

[odd ember]

has to be done over time

[distant grotto]

delta time input?

or do i need to make it loop for the amount of time i want it to interpolate?

[coral lance]

my gamemode has the player character of my choice and it is still not working

[dawn gazelle]

Have you altered your game mode or game state? If you're using a game mode that inherits from Game Mode Base, you need to use a Game State that inherits from Game State Base. If you have a Game Mode that inherits from Game Mode, you need to have a Game State that inherits from Game State.

[odd ember]

you can't use loops, you need to use tick or or a timeline or a timer

[coral lance]

I have left the gamestate default like as it came but I have changed the gamemode. Before it worked but now it is not and I am not sure what happened

[dawn gazelle]

So by default I think just "Game State" is used. Check the parent class when hovering over your game mode.

[low birch]

So if the change to the gamemode is when it first started to cause an issue then I would comb through that new gamemode you switched to as it'll be your problem causer. Give that a good comb and cross reference it with the other gamemode if you have to.

[dawn gazelle]

So that's the problem most likely. Reparent FGGamemode so it's parented to just GameMode.

alternatively, create a gamestate and parent it to gamestatebase and use that game state.

[coral lance]

I have decided to scrap that project and create a new one its all working I didn't lose that much work and eveything is going smoother than before

[tranquil abyss]

im trying to set focus on a little list when I press Q

Ive tried a few focus node but nothing seems to work

I also want the scrollwheel or some bind able buttong

to go up and down

(and I want player movement to still be active)

[icy dragon]

Try just passing event calls to the widget. You don't have to actually focus the control into the widget.

[tranquil abyss]

hmm

but if I dont click on it the arrow keys dont move the selection up and down

so

🤔

[icy dragon]

So you don't actually want to retain full control to the character while the widget is up?

[tranquil abyss]

All I want to do is

[icy dragon]

In that case, Set Input Mode To Game And UI

[tranquil abyss]

when I press Q it shows the widget basically

want scroll to change the selection

and then I click to activate

[tranquil abyss]

I want to move still

the character with wasd

[icy dragon]

So you actually want to retain full control to the character?

[tranquil abyss]

I guess so

Im trying to find a vid to explain it

[icy dragon]

Because the way I envisioned it is to call events from the widget in Player Character BP

Including scroll mouse input

[tranquil abyss]

Bascially the only things that changes is what my Click does

when the menus is up

So would I need to cast to the widget in the player

or the other way around

https://youtu.be/rpT3GQr3ioc?t=285

@icy dragon like here, The menus comes up and up can still move

but the attack button uses the ability

instead of swinging the weapon

[low birch]

When the widget is displayed you may want to switch controllers that will interact with the widget the way you want to. - It's an interesting ability menu to solve though.

[icy dragon]

So what you want to do is do a branch to check if the widget is up, then call the event in widget on mouse click if it is.

[tranquil abyss]

ok how do I move up and down the selected widget

unaware of a node that does something like that

and also if I create the widget with q

and the widget has no focus wont scroll not do anything?

[tawdry surge]

Anyone ever come across this?
I have a widget that displays the player's current money, but for some reason it's jumbling the text and not clearing the previous value when it is re-set

[wicked osprey]

Guys, how can I make a dropdown list of row names like in data handle row? I need to be able to select only a list of names, and the data table was already set inside the class and it was not available for instance editable.
So that the name can be chosen as in the enumeration

[wind void]

Like a dropdown interactable IN game? or via your blueprints?

-=-=-
Is it possible to create Timelines dynamically? If not, how do I get 15 timelines each just copied and then slightly delayed from the previous?

[wicked osprey]

When placing on the map, in the actor properties

I want to get the same list that I get from the data table row handle, but only separately so that the data table is not instance editable, and the list of table rows is instance editable

[dawn gazelle]

Where are you creating the widget?

Like, which blueprint?

[tawdry surge]

Character BP

[dawn gazelle]

On begin play I assume?

[tawdry surge]

Not sure why that would make the text jumbled

Yeah, but the default value sets fine

[dawn gazelle]

So that's the problem - looks like you probably have multiple characters in the scene. Each one of those characters fires its begin play, and the local player keeps creating more and more widgets overtop of one another.
Use a HUD class or the player controller, but not the character.

[wind void]

This?

[tawdry surge]

Nope. One fps character. 3rd person ones don't have it

[dusk dust]

hello, my widgets seem to delete themselves when they go off screen and I move back to the space they were in

anyone know why?

[dawn gazelle]

Well, you do have multiple "FirstPersonCharacter" in your scene.

[tawdry surge]

Must have spawned a second one for no reason.. ok

[dawn gazelle]

Can even see it standing around:

lol

[tawdry surge]

Have to file that away incase that happens again

[tranquil abyss]

if im focused on a widget I can press up and down arrows to select different parts of that widget, how do I change the functionality to a different key

maybe im not understanding what focus means

here

Character

Ability list

Ability slot

looks like that

pressing the buttons do work and once im clicked into it

i can arrow key and Enter key and it also works

[dusk dust]

well I guess no one does, anyway I figured it out. I was using tick, instead I used a looping timer

[hollow steeple]

So i got basic doors working, but I'm extremely lost on how to create a lock system that uses multiples keys. IE - Multiple doors each require a different key. Anyone able to help?

[dawn gazelle]

Well, multiple keys requires some way of identifying the keys.
You could use GameplayTag on your key actor, and a GameplayTagContainer on the door and on your player to determine what keys the door requires and what keys the player has.
When you pick up a key, you add the gameplay tag the key has to your GameplayTagContainer on your player.
When you go to open the door, you can do a check if the GameplayTagContainer on the player contains all the tags that the GameplayTagContainer the door has, and if it does, it unlocks it.

[hollow steeple]

Gotcha, i will see if i figure my way around and get that to work

[dawn gazelle]

So then on the door when you want to unlock it, you could do something like:

[hollow steeple]

So would that be sperate code added to my door blueprint or would i be attaching that into what i currently have for a basic interactable door?

[dawn gazelle]

If you have an interactable door blueprint already, perhaps consider creating a child blueprint that contains the locking logic then you have lockable doors and unlockable doors as separate actors since they have different behavior and you just need to override the opening logic in the child.

[hollow steeple]

I havent gotten the locking mechanic yet, its currently just a basic interactable door but i will look into locking mechanics

[dusk dust]

how can you hide widgets when occluded by other objects?

[orchid veldt]

Can you give an example of what you're trying to do?

[dusk dust]

@orchid veldtim trying to hide a widget when it is behind a wall for example

treat it as if its a real object even though its stuck to the screen

[pulsar path]

i have an actor with a variable string that i set per instance of it, with the string changing some minor physical details of the actor. at the moment it only accepts a certain few values, but i expect the list to get larger as i create more of my game.
I was wondering if theres a way i can make a drop down list of all the values it can accept? kinda like when creating blueprint nodes or selecting variable types. then i dont have to worry about typo's and such.

yes im aware that this probably isnt the best way to go about what im doing but this is the way i already have it settup and i just wanna focus on other stuff rather than rethinking a fairly minor part of the game

[devout latch]

Use enums

[pulsar path]

i will take a look at that

[devout latch]

How many different values will you have?

[pulsar path]

i have no idea, i expect there to be quite a lot though

that worked perfectly, thanks so much

[devout latch]

Great - there are some limitations with how many values you can use so if you will have less than 256, you are good!

[pulsar path]

good to know, i honestly have no idea if i will reach that or not, but i doubt it

theres just a lot of stuff that has to get figured out, im still just working on mechanics rather than content lol

[midnight otter]

YAY, MORE AI PROBLEMS! For some reason when I load to a different level, the AI does not work. I have NAV Mesh bounds on both levels. No matter where I start the AI will work, but when I load to another level, it just doesn't.

[wicked magnet]

Right now I have a hacky piece of scripting where I am switching between two different ExponentialHeightFogs in my level. It's a quick way of switching between two very different settings inside the level blueprint.

I was looking to Cast to them directly inside an actor blueprint, but it seems I can only cast to the ExponentialHeightFog class, and not individual heightfogs? Is there a way to target different exponentialheightfogs via actor blueprints? I know this is wacky, but this is just for a quick prototype.

[cursive path]

hi how to reset jump count without touch ground

[bleak swift]

Do Software Cursors run Blueprint?
I've setup a system to switch cursors with a animation all in 1 Widget
And I've called it on the hover event in my Main Menu Widget
Though nothing happens even setting visibility of Widget's do nothing

[dawn gazelle]

Jump Count is marked as Blueprint read only. You'd need to use some C++ to be able to reset it without touching the ground.

[cursive path]

that really bad i bad with c++

[cursive path]

i just use launch but my work around took long time now

[waxen knot]

so im trying to make a wondering AI but for some reason its not working

anyone know why

[gentle urchin]

Missing nav data?

Bet it fails

That or out of nav bounds

is there a way to use DrawDebugLine in game?

[short pawn]

Hi guys, Is there a way to do something in game once the game is Unpaused? my options menu pauses the game and I have it set and save variable , but not run the function. once i go to a new level it has the variable saved and working thougyh

[spark steppe]

well you can do anything when you unpause it

[short pawn]

How do i get the blueprint to check if its unpaused though

[spark steppe]

isn't it you who pauses and unpauses in the first place?

so wherever you unpause you can run a function

[short pawn]

yes but pause is on a button toggle

[spark steppe]

and?

[strange junco]

ok so im trying to make the camera tilt left if the player is moving left and tilt right if the play is moving right but i cannot seam to get it to happen smoothly

this does work but if you click it too fast sometimes it just locks up

[rough cedar]

What is a good way to check the amount of time since the player last moved?

[short pawn]

and thats the whole question. how do I fire a function once the game has been unpaused?

I have it listening for the input action and then firing an event that pauses the game and opens the menu, how do i get it to fire another event once it unpauses?

[short pawn]

You can create a timer that adds an increment to a variable every second. then when the player moves set the variable back to 0

[chrome nymph]

how do i correctly set the camera for a playercontroller?

[rough cedar]

Thanks! I'll give this a shot!

[chrome nymph]

i realise that's a really shitty question but

here's what i'm trying to do

i have a 2.5D side scroller, and i'm trying to get the world location based on the cursor

it somewhat works, but its a bit off

[hybrid ether]

Is there better way to do this more optimized? Red area especially. it's function that is fired when you remove item from item chest. input is item that you are trying to remove.

[chrome nymph]

the problem is much more exacberated when i use a camera that isn't bound to the actor

i.e. a stationary camera in the level

i'm not sure if the problem is how i'm translating cursor to world space, or how i'm using the camera

i suspect it's the former.

[chrome nymph]

does anyone know how to translate the location of the cursor correctly to the world space?

it can be drastically different

[mental trellis]

Where is yoru cursor in that second image?

OK. My Google-fu has been failing me. I can't get a clear answer anywhere.

Let me rephrase this, i want to "animate" the platform so when the player pawn overlap it to show that is "pressed" so basically i want to change the Z value . I want to accomplishe this smoothly so i added a timeline. Why when i plugged the output 4-0 from timeline on to button mesh Z location doesn't work ?

[fathom spindle]

Hi all, struggling with collision profiles. I have two objects (one of them a ragdoll) that are both simulating physics and can be grabbed by a physics handle, and i need to turn off collision between the grabbed object and all of or preferably portions of the ragdoll when the grabbed object is within a certain distance

for starters just turn off the collision of the object with the ragdoll when its grabbed, but keep it simulating physics and being held by the physics handle otherwise

[wicked osprey]

How he did string like enum?

[obtuse herald]

With enums?

[wicked osprey]

that's when you make instance editable on data table row handle, you can select data table and row like enum. Is it possible to do the same just not inside the data table row handle? So that in the editor I can select only a line from the list, and not the data table and the line together

[wicked osprey]

No. I want to do as in the data table row handle, only that in the instance editable editor there is only a row selection, and the data table has already been drawn in the blueprint class itself

[obtuse herald]

Ah you mean having an enum with the row names of a certain data table?

I don't think that works

[wicked osprey]

If I make data table row handle instance editable, I can select both data table and row in the editor, but I would like the editor to display only a list of rows

[wicked osprey]

Yes

I just want to make it so that I can't select data table with weapons in PickUp Keys😅

[ocean bluff]

Hello, is there a way for the rope (cable actor) to wrap around objects/characters in the level? right now it goes through everything.

this is the blueprint for the rope tool so far

[scarlet pumice]

hey - I have derived a C++ class from UBlueprint but it always shows as "Failed to validate" because the GeneratedClass member is always null.
I'm confused because the object actually works ok, I can call functions on it and they run, print strings, etc.

[scarlet pumice]

I changed the base class to derive from UObject instead of UBlueprint and it is working ok - I think I was confused about how to do it!

[scarlet pumice]

Function ' Create Dynamic Material Instance ' is unsafe to call from blueprints of class ' Level Generate Script '.

ULevelGenerateScript : public UObject

Any ideas how I can fix this?

[earnest tangle]

Don't call it from a level blueprint's construction script

At least I'm assuming this is what is causing that

[remote obsidian]

Is it possible to trigger an input mapping via blueprints?
eg. my axis mapping "RotateHorizontal"
Can I trigger that from somewhere in blueprints and provide a value?

I can only find ways to link it to actual button presses on some kind of controller

[lunar fog]

Bit of a general question here about how to structure blueprints.

I constantly find myself thinking about how to structure my BP's, should I put this function in this class, that class, the gamemode, or whatever.

It occured to me that I could put 90% of my functions into function librarys instead of blueprint classes. It seems like it would make life a lot easier in several ways:

• I'm less likely to have to refactor code to make a function usable outside of it's original context
• I'm less likely to repeat work by writing similar functions in different classes
• There will be less functions cluttering up my classes making them a better and clearer "high level" overview of the object
• All of my functions can be organised according to what they do, rather than the object they are supposed to work on

When taken together, all of these things seem like they would be a massive, massive improvement to my workflow and reduce some major headaches. I'm not saying I'd be religious about putting functions into librarys rather than classes. But that perhaps it makes sense to tilt the scales heavily in that direction.

What are other peoples thoughts on this, can anyone think of some compelling reasons why this is a bad idea?

edit:

In addition to this, if a function really only ever needs to be used inside of a single class, there's a 50% likelyhood that it only needs to be used in one place. So in this case, why bother making it a function at all, and instead why not just collapse the nodes for organisational purposes and for scoping variables. It's so easy to then convert that to a function anway, but you save yourself the headache of naming the functions, having a cluttered list of functions and wondering where-else that function might get called, which makes you afraid to refactor.

[lunar fog]

You could just add an indirection layer by events. Have your input mapping trigger an event, and then you can also call that event via blueprints or however else you like.

[remote obsidian]

True, It seems like that's the way I'll need to go, a bit of a shame it's not possible to call to trigger inputs directly and this extra layer is required
Thanks 🙂

[odd ember]

generally the idea of putting input controls anywhere but player centric blueprints would violate coupling

the best way to get around this is allow interactibles to "register" themselves to the player, and the player choosing which is the correct interactible

[obtuse herald]

You define functions for a Class to make it usable for other classes

Putting everything into a library restricts you to not being able to edit any variables outside the function

For example if you create an inventory component, you want to give it some functions to add or remove items from the inventory

[mental trellis]

A class is really just a set of variables with methods that work in conjunction with those variables.

[obtuse herald]

So an outside standing class has the ability to add or remove stuff from it

Yet it can't be done in a function library because you need the inventories variables

[mental trellis]

I mean, technically, you could just have a static array of variables and a library to work with them.

But that's kinda not what you should be doing.

[obtuse herald]

Well, yeah

But you will e d up with spaghetti code via that workflow

[mental trellis]

Nobody wants spaghetti code.

[lunar fog]

I'm not talking about dumping functions in classes entirely. Just 90% of the time, since I run into functions that need to be re-used in different classes so often, it seems like a smarter way to go to just build that re-usabiltiy into them directly and store them in a function library. Isn't it better to not modify parameters directly in functions anyway and to have functions just be responsible for their own state, and then return a value to wherever the function was called from so that It can be used to set whever variable you want to change?

Then if i really need to do something like setting a class variable via a function, I implement that function directly in the class - IF it even needs to be a function instead of a collapsed network, which for those kinds of specific use cases might be the case like 50% of the time anyway where that function only gets used once.

[mental trellis]

And Italian ones.

@lunar fog It's fine to make library functions (e.g. FMath has a lot of them) but naything class-specific should go on a class.

If you have multiple classes using the same type of stuff, consider multiple inheritance or just regular inheritance.

[lunar fog]

@mental trellis I guess that I've just realised I'm probably not using function libraries nearly enough in my own workflows and that it would tidy up and create a much more fluid way of working.

As for inheritance, my understanding is that it's better to avoid that most of the time or at least to be careful with it and to use components instead.

[mental trellis]

No.

That may be a Unity way of thinking?

Inheritance is fantastic in UE.

The trick is to know when to use it and when to use components.

[obtuse herald]

and when to use interfaces

[mental trellis]

Components generally offer discrete functionality.

[icy dragon]

Definitely Unity way of thinking, because I'm certain Unity relies more on their component equivalent than inheritance

[mental trellis]

Like a movement component will deal with the movement for an actor. Or a primitve component will deal with rendering a mesh or something.

If you have things intrinsic to the actor, they should be on the actor, tbh.

I guess I kinda view actors as component managers?

[obtuse herald]

Hmm

[mental trellis]

Plus their own stuff.

[lunar fog]

I don't come from Unity, I've been an Unreal user for a long time, although I don't have a programming background or education

[short pawn]

is there a way to call a function from a widget bp from a player controller bp?

[obtuse herald]

I would say components extend actors

[icy dragon]

Well, do get used to object oriented stuff.

[mental trellis]

I guess, yeah, @obtuse herald

[chrome nymph]

how do you attach an actor to another?

AttachACtortoActor doesnt seem to "bind" it

[mental trellis]

Tbh, the whole actor/component stuff in UE is a bit vague.

[obtuse herald]

It kinda is

[mental trellis]

Most of everything in UE is a bit vague.

[icy dragon]

What

[short pawn]

ive tried that but it won't call the function

[lunar fog]

I've been writing bp's for quite a while, and I'm just exploring some new ideas (to me) about how to structure things differently.

[mental trellis]

@lunar fog there's really no wrong answer when it comes to all this, it all depends on how you like to program and how you think your program should work. If it works and it's performant, go for it.

[chrome nymph]

is there a way to bind an actor to another actor?

[obtuse herald]

Nothing stops you, experience is the best teacher

[short pawn]

this first image is where i am calling the blueprint from my player controller

this is where the function in the blueprint isn't printing the ohno string

[surreal peak]

Are you getting AccessedNone errors when you stop playing?

[short pawn]

ive even tried toggling the breakpoint and it doesn't do anything

[surreal peak]

My questions remains

[short pawn]

no errors

[surreal peak]

Do you get a print if you place it directly at the start of the GO function?

[short pawn]

yes

[surreal peak]

And what exactly is the code between that? Your last images doesn't show that

[short pawn]

its just getting a variable

ive tried with the string right after the go function too

[surreal peak]

I meant here

Does that print if you place it there

[short pawn]

yes ive tried that

no print

[surreal peak]

Then the function isn't called

Which brings me back to the point that the reference you are calling it on is invalid

What are these?

Where do you fill that BlueprintRef variable

[short pawn]

i call that function everytime the game opens and it works

it is a widget

that other circle on the left was blueprint ref too ive been trying for a while sorry i cleaned it up with only one blueprint ref and still nothing happens

[surreal peak]

Where do you fill the variable

If this is a Widget, then you are creating the Widget somewhere

You will have to show your code

[short pawn]

its a variable that is a reftrence to my widget

[surreal peak]

With those cropped images no one will be able to help properly

[surreal peak]

Yeah but where do you fill it?

That's just the Type

Where are you setting it to an instance of your Widget

Reference variabes are empty (null/nullptr) by default

They are containers that can point to an instance in your memory

But you need to set them to an instance for them to actually work

[short pawn]

ok thank you. how do i set an instance?

[surreal peak]

Where are you spawning the Widget

[short pawn]

get all ?

[surreal peak]

No, not GetAll

GetAll is the devil

You are creating your Widget somewhere

The CreateWidget node returns the reference

[short pawn]

it is already created by another blueprint by the time im trying to play the function

[surreal peak]

You will need the reference

C++ (which BPs are) is all about references

You can't just magically get those

Imagine you spawn you widget 40 times, which one of those is your variable pointing to?
