[manic comet]

??

[lofty rapids]

interesting

[manic comet]

even here

[lofty rapids]

show your inputs

[manic comet]

the function one??

[lofty rapids]

where you are trying to set hit as output

show your inputs, you have one called HIt ?

i think that may be the conflict

[manic comet]

its Hit oni right

[manic comet]

i renamed that

[lofty rapids]

that should fix it

[manic comet]

its not lol

do i hv to put some sort of plugin or somthn??

[lofty rapids]

no you have a conflict

show the bp

[lofty rapids]

compile it and save

then try again

[lofty rapids]

you changed the input ?

and compiled ?

do those two things

[manic comet]

the name is Hit from the begining oni

[lofty rapids]

do you not understand what i wrote ?

show your inputs and outputs

not just the outputs

[manic comet]

is it cuz of this??

[lofty rapids]

it's because you have an input Hit

repeating in text is wild lol

people skim stuff ig

[frosty heron]

Is there a reason to commit name shadowing

[lofty rapids]

yes

[frosty heron]

Just name your variable uniquely

[lofty rapids]

you can't have input and output same name, this is your problem

[manic comet]

bruh then in dis vid???

[lofty rapids]

the inputs are your "function parameters"

[lofty rapids]

they also mispelled length

[manic comet]

😭

[lofty rapids]

idk maybe a differnt version supports it ?

[manic comet]

bruh

ill just roll with it and see

this is pain

[lofty rapids]

it doesn't matter what you name it tbh

[manic comet]

hmmm

[narrow sentinel]

so i've got a wierd issue

i do this to create a menu widget when player wants to

I then do this based on the button press they do on the widget

first time they say clicks resume game works fine

[lofty rapids]

do you create this widget more then once ?

[narrow sentinel]

this code runs, however I have an odd issue where the second time they open the menu this resume game event seems to fire when they try to resume game by the ESC key which is done by this

.

[narrow sentinel]

no just once

[lofty rapids]

you have two of the same event ?

[narrow sentinel]

do I

[lofty rapids]

well by what your saying

your saying it runs another resume game ?

not the originally ?

or what are you saying is the problem ?

[narrow sentinel]

i found the issue

it's this

that spawned menu var isn't correct so the second time they try opening the menu it'll fail does the resume game function

[lofty rapids]

so what your saying is it's going to false ?

[narrow sentinel]

yeah so I never nulled the spawned menu ref after removing the menu so after the first occasion it was being seen as a valid ref even though the menu was removed from parent etc

so it bassically was acting like menu was open when it wasn't

[frosty heron]

you can just convert that to validated get

less nodes

[manic comet]

it failed

[dense hinge]

Have you looked into GASP? It does that, but it's also dependent on animations

[frosty heron]

You mean the leaning bit?
most likely just using blend space with direction as the value.

[narrow sentinel]

love it how widget work fine both in PIE and standalone game but then in game packaged build they oddly don't work the same

[maiden wadi]

In whaat way?

[narrow sentinel]

on one of my widgets a button etc appears when the ship is in position however in packaged build this doesn't seem to happen so just checking I've not done anything wierd so barewith

is there a way to see if the game is packaged build or not ?

[lofty rapids]

are your anchors correct ?

for instance if you have something on the right side, are you using the right anchors ?

[narrow sentinel]

only asking cause I do a PSO loop checking but because it's editor the PSOs have prob been done already

[lofty rapids]

^

this would probably be an issue when you open a window compared to pie

like if you have something on the right side, but it's set to a left anchor

it might scoot off screen

[narrow sentinel]

I reckon I've prob logic somewhere

[lofty rapids]

check your anchors for sure

[narrow sentinel]

so turns out which is what I thought it was user error issue

bassically handed double checked stuff still worked within the gameplay level and only checked stuff worked in test playground level so was actually really simple issue

[jagged moss]

can someone explain to me the correct way to get info from one actor into another and get info from an actor into a widget and explain it like I'm 5.
I'm watching video after video but I just cant understand it fully ._.

[lofty rapids]

so the idea is you have variables in a blueprint right ?

and those variables are a part of that blueprint class

[waxen ice]

It will be easier if you say us what is unclear or what exactly you want to achieve and how you try to do it

[jagged moss]

give me a moment ill give you some pictures

The sleep event happens on an actor, when that actor sleeps it creates a integer, i want the integer to be written out on the widget text block.

The only way i have been able to change it was with create widget but then it just creates a number on top of the other which just becomes unreadable. what is the best way to update the integer that is created when the actor sleeps

[jagged moss]

but if i do get widget from class, how do i then make sure it knows which textblock to send the info into?

[lofty rapids]

so what you want to lookup is "references"

you create a reference to the widget, then you use that reference

to get the variables from the widget

[lofty rapids]

don't do get widget from class, create your widget, promote to variable

use that reference

do the create and promote on begin play

and just use the reference when you need it

[jagged moss]

i do that on the character, but this happens on a seperate actor

[lofty rapids]

i usually put these in the HUD, but for simplicity begin play is fine

[lofty rapids]

right so you need to get actor of class, your player

then pull out and get the reference

or even get player pawn

but your missing piece is "references"

[jagged moss]

give me a moment to try

[lofty rapids]

so you promote to variable on the player, this creates a new variable that lives on that player or whatever bp you do this on

[jagged moss]

like this or am i still off?

[lofty rapids]

why are you setting the reference ?

in the first image you set it

what are you trying to do in the second image ?

[jagged moss]

i can swap it to a get, but im confused how i get the integer sent over to the widget

[lofty rapids]

well based on image #2 you need a bit of learning about how blueprints work

specifically variables and there scope

and references

[lofty rapids]

from my point of view, i have no idea what your talking about

[jagged moss]

yes, thats what im trying to understand. i am lacking a lot of info and im taking some courses etc, but im always so confused how getting information between them works

[lofty rapids]

it's pretty simple

[jagged moss]

when it comes to getting information between classes you are very much correct. I am very new to all game making

[lofty rapids]

get the reference, get the variable

variables live on a class

you need to access that class to get the variables

and each reference is an instance of that class

so when you create the widget

and promote to variable

this variable lives in whatever blueprint you do that in

and to get it from another

you need a "reference" to the other blueprint

then just drag out, and get the variable

[lofty rapids]

https://www.youtube.com/watch?v=2EN6gKuTzoE

videos not helping ?

[jagged moss]

ive been watching a lot

[lofty rapids]

your missing some basics

you probably need a blueprint tut

[jagged moss]

but i always get confused, i feel like i did understand it a bit in the past but after coming back im struggling more

ive done some in the past and i am following new ones too

[lofty rapids]

you can scroll up and read what i wrote

thats about as basic as it gets

the data lives somewhere

you need to get access to where it lives

in order to access it

and get actor of class is a good choice

if you have no way of targeting the actor

personally ...

I put my widgets in the HUD class

this allows me to get them from anywhere pretty easily

but it's easy just to use begin play of character, just if you die and respawn it will fk it up

[jagged moss]

i feel like part of the issue is that there is so much to learn and when i try to create something i always learn something new a bit to late. i have been able to make a lot in the past tho, so some parts i get and some i just dont

[lofty rapids]

everybody learns different

your missing "scope", "references", and "variables"

mostly scope

[jagged moss]

when getting info between character and widget in the past i found it pretty easy, but now that i need it from an actor it feels so difference, but i have now been able to get the right variable into the actor

[lofty rapids]

ok good so it works ?

[jagged moss]

no, im probably messing up somewhere else, but im gonna try to change things around a bit to see if i figure it out

on begin play i made a reference from the return value of the create widget, then i made a reference again from the variable i want to change, is that correct?

[lofty rapids]

why are you make a reference again ?

your adding stuff that isn't necessary

just make the reference

and then when you need to access it

get the thing, and access it

...

[lofty rapids]

maybe try this
https://dev.epicgames.com/community/learning/courses/LWv/unreal-engine-blueprint-communication/ypKl/unreal-engine-blueprint-communication-overview

[jagged moss]

nice, yea ill have a look into that one

so on my actor i now have event-> setting variable->Get actor of class which is character->set variable tied to widget
Am i still off?

[lofty rapids]

idk take a screenshot ?

if a ss is a pain theres also blueprintue.com

which is pretty cool site

[jagged moss]

so when i drag out from get actor of class it does give me the option to choose the variable and im guessing also setting it to the wanted integer

[jagged moss]

yea ive used it a bit

[lofty rapids]

what are you doing here, setting a variable on the character to top face name ?

top face name is the valid number ?

so now you set the variable on the character

but that doesn't do anything with the widget

unless you use bind

honestly i would just use now bind in the widget

or even set the variable on the widget itself

by dragging out of the get actor of class, getting the widget ref, then setting a variable on the widget

then bind the value to the text

probably would be best bet

this way when you change the variable on the widget, it would update automatically

[jagged moss]

yea that worked, when i did it i remember thats how ive dont it before. i dont understand how it knows when to update without an event saying it but does it just get it everytime it updates?

[lofty rapids]

i think the bind is just like having it on tick basically, i'm not sure how it works under the hood. but in theory its the same as having it on tick as far as functionality

[jagged moss]

ill have to look into it as i try to avoid ticks as much as possible

i think that is what confused me before but i think this was how i manage to "cast" before to by making a bind too

thanks for the help tho ^^

[shell tide]

Yeah keep it up @jagged moss , I'm learning blueprint communication too. I’m still working on understanding the Cast, and I’ve put together something to practice. So I have a BP_CubeGuy with a FirstName variable exposed, and I dragged two instances into the viewport. One is named CubeGuy1, and the other is CubeGuy2 (as indicated in the FirstName variable).

The Cast starts from a BP_Hero that is not placed in the viewport but appears after the game starts. The goal is to display CubeGuy1 when I press A and CubeGuy2 when I press E. Here’s the result: everything works perfectly, but is this the right approach?

[charred granite]

Hello, does anyone know how I could solve the stretching on the angles of this pyramid shape? It only seems to occur on triangle shaped stuff, I tried googling a solution but cant seem to find the cause of this.
I'm using 2 different shapes for this material, so that's why I decided to go with World Aligned textures/nodes. My blueprint below :

[lofty rapids]

now remove one from scene, then add one back to the scene

and you see they are flipped

this is a bad way to get specific actors

[jagged moss]

to update widget i did this, it seems to be the easiest way, also when adding a print string i can see it uses ticks so it might be a better way if you want to save on the ticks a bit. the only thing happening on the actor now is setting the variable

[lofty rapids]

nice, now your dice roll and you get the actual number ?

cool mechanic dice roll i made a game that uses that but have not actually done 3d dice yet, might try it out

[jagged moss]

yes, there is still some kings that im working out but the dice works pretty well and my mechanics for it was simpler than what i found online, just an issue with rolling multiple but i think i understand the issue

[lofty rapids]

ya i think i'm going with the component on each face, highest z approach as well

seems like the best way to do it

[jagged moss]

i think it might be even better to mark down each rotation of it and casue then you avoid "cocked dice"

thats more an issue when having a D20 etc tho, i migth do something like that later

btw, i know its the wrong channel for it but how hard is it to make material like shown on the right side here for my dice? i got the dumbest way to colour dice but its nice for making prototypes. it takes me about 2 minutes to make a dice and set its colours so when i import it i can just input any colour i want like this

from creating the dice, to colour it to import it into ue it takes less than 5 min and i can add the colour i want later

[lofty rapids]

materials are really nice

you can do so much with them

i would use a collectionparameter

whats cool about these is you can run in the viewport and change the param on the fly

[jagged moss]

i get confused by the uv wrapping etc so i avoid it and do it with stamps in stead and when its imported i get it like this, the original materials was just simple textures made in paint

[lofty rapids]

so you can get a good adjusted color

[jagged moss]

yes

but i havent seen anyone else make it the way i do and i think my version might anger some artist x'D

[lofty rapids]

i've been using colors with a macro variation

looks like a texture lol

[jagged moss]

when i import the dice theyr done with material like this setup but with simpler colours, then i applied the beginners content colours

[lofty rapids]

collectionparameter ftw

they are so nice

[jagged moss]

the only thing i did in blender is convert the file so its ready for ue

[jagged moss]

indeed

[lofty rapids]

scalars and vectors only

for collectionparameters

but 5 minute process is nice

https://streamable.com/i60i74

this what you can do while its running, dial it in

[jagged moss]

you dont really need any knowledge either, the dice i make in a dice maker program that is free, then i open it in the shittiest 3D program known to man, 3Dbuilder, then i use 3Dbuilders stamp tool and apply paint colours to the object, you can stamp as much as you want and when you click "complete" all you did becomes one material. then do that on all sides you want. save it as obj. and open in blender, convert it to the correct file and then import into ue5 and its ready to add the correct textures

[lofty rapids]

oh is that all ?

lol

[jagged moss]

yes

[lofty rapids]

it's a lot, easy for you, but a pain for me

[jagged moss]

the picture i took in ue5 is just after the import, but i changed the textures only

[jagged moss]

it takes less than 5 min if i try to be quick, but yes, as someone who know how to do it properly its probably better ways to do it x)

[lofty rapids]

so basically you import it, then set the textures on the parts

classic

[jagged moss]

when its imported it has as many materialslots as you chose to add with the stamps, then just choose what material you want

[lofty rapids]

right yes i have done a bit in blender

[jagged moss]

what usualy stops me from finishing a project is blender and colour theory x)

[shell tide]

Indeed, there are flipped... Damn. Then, what is the best way to fetch actors?

[lofty rapids]

seperate classes is the easiest

[lofty rapids]

as far as "best" depends on what your doing exactly, you could have a variable thats an enum on the actors that you get all actors of parent class, loop through and check variable value if it's set to the one you want, pick that one

[shell tide]

I see. Well I still have a lot to learn!

[dark drum]

Just to add onto what engage said, be care when using the get all actors of class. Sometimes the array it provides can be large if there's a lot of actors of the given type in the scene. Looping through them in BP can cause performance issues.

If you're wanting to get specific actors for things like quests. It might be worth you making some sort of actor manager that allows you to register and actor with a name/gameplay tag and then retrieve it using the same name/gameplay tag.

[jagged moss]

Storing the value here and on the actor using a get actor of class for the one holding the create widget, then calling the actor creating the widget to output it in the widget worked better, i think what confused me was where to store the value

[dark drum]

Event Dispatchers are you're friend. The dice can have an event dispatcher called 'OnDieUpdated' that can be called when it's number is updated.

This can allow multiple things that need to do something when the die updates can do so whilst also receiving the number. It also has the advantage of not requiring tick as things will only update when they need too. (When something has changed)

[lofty rapids]

or even a map of string->actor ?

where string is the id

[barren tangle]

I was thinking, like motocycle. when they turn you see the body move as well on the Z axis. but it's exagerate, i just one something similar but really slight

i know it's the Pitch, but i don't know how to calculate it

[dark drum]

You could but Names tend to be better for look ups. I would use Names over strings for look ups as they aren't case sensitive. Plus there's some performance advantages.

[jagged moss]

its working okei-ish atm, but how would i set this up? i am using some in a tutorial im doing but i havent fully grasped it all yet. if the dice has it, can I then call it to add it to the widget? the widget is where the tick happens currently. i could remove the tick function and add an event that gets called with the event dispatcher?

[lunar solstice]

Has anyone had issues with 5.6 and setting movement mode to Swimming?

^^ Above works when I set it to flying, but if I set it to swimming, it does nothing

If I add a physics volume and set it to Water, that works. But manually setting to swimming does not

Yeah tested in a fresh 5.6 project, and yeah, its broken

[potent bear]

Does anyone know how to setup the widget interaction component input correctly?

I currently have an actor in the scene with a widget component. The widget that it is attached has just two buttons. The widget interaction component does trigger their hover calls, but not their presses.

I currently have it set up so that input gets received from the C key, and somehow whenever I press the key to interact with the widget nothing happens. But hover calls do occur. The second image shows the widget blueprint, with what does get called, and what doesn't. The third image shows the UI in world the world, along with the print screen showing the hovers occuring.

Sorry for taking too much space with the images, if anyone knows how to fix this issue it would be appreciated.

[lofty rapids]

so you can't click on them regularly ?

or that works

[potent bear]

Nope

I can't click on them when the widget is in the world

The interaction component does call the Hover function, but not when I try to click on them

[lofty rapids]

so the hover events work, but the click doesn't ? isn't there also a pressed ?

i'm assuming that doesn't work ?

[potent bear]

The button in the UI comes from another button UI that has those two actions binded for the same call

I also did them individually and nothing

[lofty rapids]

so it's these events that are not firing ?

put a print string on the clicked in the image

[potent bear]

yep

[lofty rapids]

you already know that these are not firing

[potent bear]

yep

I can validate that they work when they are attached to a character, but not when trying to get input through the widget interaction componnet

My though was that maybe the interaction component itself isn't passing the funcitons as it should, but I have no way of knowing if this is right or wrong

[frosty heron]

You are talking about leaning. And you use direction and blend space for these.

You dont rotate the capsule at all the feet will clip the ground.

You can make new animation out of your walk and run animation, where you rotate it by 45 degrees. You then bundle those animation in a blend space and use direction to drive the leaning.

Finally that blend space will be additive to your walking and running animation.

[coarse orbit]

Anyone know what is the requirement for a BP function input variables to have description?
I tried:
@param[in] VariableName Thedescription

But it didn't work, I remember doing it in earlier versions of UE but on 5.5 doesn't seem to work, did they change how it is done?

[sand shore]

@param VarName Stuff about VarName

Each parameter description is the rest of the line following the name, one description per line, one line per description. No [in] suffix for param.

This is how I remember it working from UE4 and its also the syntax used in native C++ comments to do the same

You may need to refresh nodes or recompile or both, though

[coarse orbit]

@sand shoreThanks it did work in a normal bp however I also tried for asset action utility bp function but didn't work, do you know what might be the cause??

nvm my bad, it works inside blueprint graph but not when executed

[sand shore]

Ehh, maybe someone else can help if they want

[coarse orbit]

Thank you, maybe its just not possible you did more than enough 🙂

[narrow sentinel]

out of interest what would be the best way to extend this spline length both in x axis as I want to have them dynamic extend to the length needed.

well i have an idea of how to do it but just wondered is there a performant way I should do it

[worldly notch]

Does this make sense for a Sign In event?

I have a feeling that output pins wired from the Target - Username nodes should be wired to something, but I'm not 100% certain

Might as well be the impostor syndrome, since I'm re-learning coding as I code

[lofty rapids]

so this is supposed to sign in ?

your getting data from a save ? what is this data ? the login info ?

[frosty heron]

Keeping non encrypted password is wild imo

[lofty rapids]

well technically is should be hashed

imo thats the best way to store passwords

in web dev it's common practice

[frosty heron]

Its common practice everywhere. No one should store the actual password letter by letter

Anyway that aside you are just loading the .sav file. You can just convert that to the text, where the password should be converted to bunch of ***** for display because you dont want youe lil bro to see your password on screen. Do you have any actual issue atm?

[worldly notch]

Yes sir

[worldly notch]

Local save, at least
Will work on backend down the road

[lofty rapids]

is there an issue ? i see you left things unhooked

[worldly notch]

That is what Im not 100% sure
Compiled everything and got no error

[frosty heron]

Im not sure what you are not sure about

What error are you actually expecting?

Btw the text remains empty. You want to convert that string to the text for display.

As for the password, format first then set the text.

[worldly notch]

Not expecting an error, per se
Just double-checking that logic flows correctly

[frosty heron]

Well atm the text will remain empty unless you set a value to it.

Also provably use the set text function instead setting the text variable

[worldly notch]

These 2 for example, I have the impression they should be hooked to something

[lofty rapids]

depends on what your goal is

[frosty heron]

Yeah well tbe username text box not gonna magically fill it self

Convert the string to text and use that value for the text box

[lofty rapids]

the username and password the saved information ?

or is it the available login information that you need to check ?

if your just trying to set the texts to the saved values plug them in like already mentioned

[olive yarrow]

So... you can switch player and stuff, so i thought "ah if i just attatch this weather actor to the player controller it'll go where they are!" nah.

I'm trying to have this spawned actor go to and follow wherever the player controller/controller character is. Any ideas?

[frosty heron]

Switching player dont have anything to do with attachment. It will just look at the active camera of the new pawn is possessed.

2nd player controller dont have a real physical location. Its 0,0,0 at best.

You will want to attach the actor to the pawn you possess not the player controller.

[olive yarrow]

dangit, that's what i was doing before i just hated transfering the rain actor

[frosty heron]

You can have some sort of manager that bind an event when the controller change possession.

Where you just attach the rain to the new pawn everything the controller possess a new pawn.

Event on possess -> attach actor

[olive yarrow]

oh girl

thanks

[frosty heron]

@olive yarrow actually you can do all this in the player controller. OnPossess event will give a reference to the new pawn iirc.

OnPossess -> get rain, attach it to the NewPawn

[calm bear]

Hello, is is possible in BP to get a world soft object reference from a ulevel asset ?

[snow halo]

so I have a line trace that starts from the top going downwards
this line trace is supposed to hit my static mesh floor but it never does
instead it his all the way down to the landscape, it will find the landscape if i make it too long, but it ignores my static mesh, why?

[lunar solstice]

Can anyone verify that Swim movement mode is broken in 5.6 when setting it in code/blueprint? It works fine setting in a physics volume, but thats it

[frosty heron]

Check your SM collision setting. Also is the sm part of the actor that is line tracing? Because the bool ignore self is set to true.

[full badge]

it's always like that

[lunar solstice]

Crazy

[maiden wadi]

You kind of need water to swim. You can't swim in air, you fly in air.

[lunar solstice]

Technically yes, but the fact that it can be overridden without some hacks

[supple ridge]

Is this a bug with 5.6.0? Instance editable variable in an actor component only shows up in the details panel of an instance in the level, not in the details panel of the blueprint itself (pawn),

[modern horizon]

How can i extend a bone/joint (or group, wtv) to a specific location?

[zinc ermine]

Hello, Im using this timeline to add recoil to my game, but I noticed that the recoil is super high at high frame rates and really light at low ones, can anyone help me make this consistent across frame rates?

[proper tulip]

why is this happening? i can show code too if anyone interested in helping

[frosty heron]

You need to remove the widget from the viewport where key f is when you leave the trigger.

End overlap-> get the widget-> remove from parent

[proper tulip]

this is what i havew

[grand oasis]

Does anyone know why my Setting for Anti-Aliasing isn't being set?

[paper gate]

can someone help me here? This feels like it should be the easiest thing ever but its not doing what I want it to.

I have an actor thats nothing more than a collision box and a vector you can set in 3D space (like in picture 1). Then it sends that vector to my camera system that should just be setting to that location (see picture 2) but the end result is the camera gets set to some location off to the side?

Like im not even doing any crazy math here, is there something with the vector handel I dont understand or something?

[zinc ermine]

Hello, Im using this timeline to add recoil to my game, but I noticed that the recoil is super high at high frame rates and really light at low ones, can anyone help me make this consistent across frame rates?

[chilly thicket]

hi, i need some help. I have customers that spawn go to a shelf, take an item, go to the checkout counter, and then leave. My behavior tree works when i star a level with customers already placed. But when i use my spawner the customers get stopped when its time to go to the counter

i have all my code in bp just let me know what functions u wanna see

[lofty rapids]

so what is your timelines, 0 - 1's ?

or much higher ?

anyway, the common fix is use delta time

[zinc ermine]

it goes from 0 to 3

[zinc ermine]

i multiply the alpha by deta seconds?

[lofty rapids]

i believe so , but you may need to multiply the result by a bit to get it to be the right size

[lofty rapids]

not sure if it will help, but it's worth a shot

[zinc ermine]

it does seem to work better right of the bat

[lofty rapids]

its the usual fix

to make it frame independent

multiply by delta

[zinc ermine]

thanks dude

[lofty rapids]

so spawning a customer makes it fail ?

[chilly thicket]

It still works for the placed customers who where there prior to level start, but the characters who spawn find "none" instead of the bp_counter

[lofty rapids]

intersting

are you doing anything on beginplay of character or game to those customers that you might not be doing to a spawned one ?

[chilly thicket]

heres the bt, the placed customers get thru the whole thing, the spawned customers get stack at move to targetcounter

the bp_customer is the same for both the spawned and the placed

[lofty rapids]

so has bought is never set in the spawned ones ?

[chilly thicket]

it gets set after they finish task_buyitem, which they are able to complete but after its set and they go to the second sequence they cant find the move target

[lofty rapids]

so there having a hard time finding the exit ?

[chilly thicket]

they wont even get to that point they get stuck at move to target counter

[lofty rapids]

well your tree looks strange, i'm still learning about it so bare with me, but you have is set, and is not set ?

on the same thing ?

why do you have two blackboard conditions in each one ?

[chilly thicket]

yes so the customer buys the item but has not paid for it yet, when he buys and pays for it he goes to the third sequence

[lofty rapids]

oh ok it's two different variables

i'm obviously blind lol

[chilly thicket]

lol all good, im so stumped i cant even think up a reason why he can get to the shelf and get the item but not get to the counter

[lofty rapids]

so it's stuck on move targetcounter

[chilly thicket]

exactly\

[lofty rapids]

how do you set that target ?

i believe it's not completing the moveto ?

or it would move to the next node to the right of it

[chilly thicket]

correct, so i set it in the my customer ai controller

hes trying to complete it but he cant find the counter

but the ones that i place can find the counter

[lofty rapids]

right, but it's not finding the target, so either the target isn't set, or they can't get there for some reason

[chilly thicket]

its not setting

[lofty rapids]

show where you set the counter in the blackboard

[chilly thicket]

this is in the ai controller for the customer

[lofty rapids]

when does this run ?

on what event ?

[chilly thicket]

begin play

[lofty rapids]

you only have one counter ?

check out actos length on a spawned one

print string it

[chilly thicket]

ok u just helped me figure it out lol

so i did this in the spawner and the customer and it didnt work

but if i change begin play to on posses in the controller it works perfect

idk why i didnt try in the controller

[lofty rapids]

do you plan on having more then one counter ?

[chilly thicket]

yes, theyll be placable as well

[lofty rapids]

ok because get actors of class, get zero is just weird, you can do get actor of class, single

but if it's just a placeholder it doesn't even matter

[chilly thicket]

its just a place hold there was only one currently in the level and i just wanted to make sure it worked

[lofty rapids]

makes sense

[chilly thicket]

thanks again man!

[lofty rapids]

just you can use regular get actor of class, saves some spaghetti lol

[chilly thicket]

true idk why i did it this way, btw do u have any projects ur working on?

[lofty rapids]

yes, a few

[chilly thicket]

any on stwwam i can wiishlist?

[lofty rapids]

nothing for sale yet, i'm still messing with the engine

[chilly thicket]

facts let me know if u do i owe u big dog

[lofty rapids]

i'm currently working on water material

https://streamable.com/yahil8

it's interesting materials are awesome imo

[lofty rapids]

its np, i like to help

[chilly thicket]

thats dope are u trying to put this on fab or is this something for u?

[lofty rapids]

eventually i will be making materials and tools to upload to something like fab ...

but for now it's just for me

[chilly thicket]

thats awesome man! keep at it, and thanks for help again i had to get you on speed dial

[high stratus]

is there a way to switch between two cameras of different actors, for example: I have a player, yes I know how to swap cameras within a player, but, whenever I try to swap it onto stationary camera of a different actor.. it seems that FOV been changed but the camera - doesn't

[gentle urchin]

Using SetViewTargetWithBlend?

[barren sonnet]

When I spawn a geometry collection and cause it to break by running into it or impulse, the level 0 collision for it still stays and blocks the player. Anyone know how to solve this or what might be causing this?

[inland walrus]

@lofty rapids hey, sorry to ping but I figured you'd know the most when it comes to this since we worked on it yesterday

I wanted to move the potion names from an array to a data table, so I swapped the 3 parts where it uses a array and for each loop with break to use a data table instead... but now it's only printing 2 ingredients instead of 3 (When using 3).

Any idea on why? (I've commented changed so you know what is updated)

[sturdy swan]

Anyone got a good video on how to create a shop system or more or less a npc interact system to do deals with contraband

[lofty rapids]

ok so it's not matching the amount of ingredients ?

or it is but, you have 3, and it's saying you only have 2 ?

[lofty rapids]

i think the problem is in the original logic

i believe you did everything correctly

but the problem is it's matching the total of the ingredients not the total you have in slots

does that make sense ? it's getting 2 from the ingredients, and then saying yes you matched two of them

[inland walrus]

Yeah that makes sense

[lofty rapids]

instead of saying you have 3 slots, match one with 3

[inland walrus]

The original logic worked though which is strange, unless it didnt and I was just unaware of it

Thank you for the response btw

[lofty rapids]

you probably just didn't come across this, it's whats usually called an "edge case"

where the logic has an issue, usually at a low percentage of the time

[inland walrus]

I see

So the issue is the branch

[lofty rapids]

yes, the check at the bottom right

where you say do my matches, equal this total

[inland walrus]

So it's always getting 2 before it gets chance to get 3

[lofty rapids]

what you want to do is figure out how many slots are filled, and use that number

[lofty rapids]

yes most likely

[inland walrus]

I thought thats what we was already doing here

[lofty rapids]

for instance if they were ordered the opposite it would get the one with 3

[lofty rapids]

we are checking the amount of matches to the current recipe

nothing to do with your slots

well

the isvalid is for your slots

and it does match the slots lol

[inland walrus]

Ah ok, so basically make a new variable on the add ingredient button it +1 interger

[lofty rapids]

so you need an integer

and you need to figure out how many slots are filled in your inventory

[tame bay]

Hello there ! I was following a little VFX Tutorial with a blueprint part in it to add some movement to it, and make it follow the ground.
I'm very new to blueprints and there's a compile error I don't really understand in the FollowGround BP (I have the exact same as in the tutorial which doesn't have the error)
Does anyone have an idea as to why ?

[inland walrus]

Gotcha, I'll try that

[lofty rapids]

you can do this at the beginning before the rest of the code, just check if isvalid index 0, if so add 1

then after the three checks you'll have how many slots you have filled

and use that integer instead of total from the recipe

[tame bay]

As you can see in this part of the tutorial there's no error, hence my confusion

[inland walrus]

Using the same invalids? but just do it before it runs the loop?

[lofty rapids]

different ones, new ones

well not before the keys

[inland walrus]

Got you

Would it be 3 different branches again?

[lofty rapids]

can you show a picture of the whole thing thats in the video ? because i can't tell what kind of blueprint it is

[lofty rapids]

yes

set the integer to zero before the three

[lofty rapids]

you can do another sequence

makes it cleaner

[tame bay]

Here's the other part

So about the exact same thing as I have

[inland walrus]

Wouldn't that cause an issue if say the user does this? (leaves the middle or top one empty?)

[lofty rapids]

you have the wrong get owner, you want target is actor compont

you can see the different

[lofty rapids]

no it will be fine

you will get 2 at the end

[tame bay]

Yeah I saw that when taking the screens

[inland walrus]

I see

[lofty rapids]

do another sequence

with four pins

the top three the checks and adds on true

the fourth continue the execution

[tame bay]

Thanks !! I didn't look at the other get owner possibilities since it showed this one first 🙂

[inland walrus]

Got you, is this right? (not plugged in yet)

[lofty rapids]

yes but there is a ++ node you can use

which automatically does the + 1 and set

[inland walrus]

Got you, you mentioned putting a set 0 node before the 3, is that before the 3 branch or after?

[lofty rapids]

right before the sequence

so that every time it runs, it sets it zero, and gets the amount you have filled

if you don't reset to zero

this number will just keep increasing every time it runs

[inland walrus]

gotcha

Now I need to do a check here, does it matter if I do it before or after the current branch?

Probably before

[lofty rapids]

just change the bottom number to the new value

no new checks

same check

[inland walrus]

oh okay

[lofty rapids]

different value

[inland walrus]

so we dont need total anymore?

[lofty rapids]

plug the new number into that dot

[inland walrus]

like so?

[lofty rapids]

it should work give it a try

[lofty rapids]

hold on i think you need more logic

i think you want the total number

yes

put back the total number

and add an AND

so check if it equals matches equal total

and if the total matches the new number

that will fix it

[inland walrus]

the bottom reroute is the total

perfect, it looks like its worked

[lofty rapids]

no the bottom one, ingredients added == total

[inland walrus]

Oh

[lofty rapids]

the total from the recipe

so if the recipe amount matches

[lofty rapids]

and the total slots is equal to the the amount in the recipe

ya that should do it

[inland walrus]

Thank you so much man

[polar barn]

I need some help with this Blueprint I have where it needs to be 5 before the mesh can be spawned
but I don't know how to make it where once its completed it subtracts 5

[lofty rapids]

in this case just set the variable to zero

drag out from the cast and do set currency

put that on the true execution

just set it to zero

or you can subtract 5 but it's hard coded anyway

if you want to subtract 5, make a variable which is the amount, then get the variable, subtract amount, set the variable

[steady wolf]

yo can anybody help me make a blueprint that when a oject moves a animation plays?

[lofty rapids]

what sort of animation plays ? is the animation on the same object ?

[steady wolf]

like a walking animation

[lofty rapids]

so do you have the animations already ?

[steady wolf]

yes

[lofty rapids]

is it just one animation you want to play ?

do you have an idle animation as well ?

[steady wolf]

i mean i do but idk if il use it

[maiden wadi]

Need to check out how to implement an animation blueprint and specify it on the skeletal mesh.

[steady wolf]

or like can i make it so it detects when im moveing and how fast so i can make joging and sprinting later

[lofty rapids]

probably #animation can help, you want a simple anim with blend space and probably a slot

[steady wolf]

il ad that later tho not now

[steady wolf]

thanks

[lofty rapids]

yes by using a blend space which just blends based on an input

so you would put your velocity length in there and that would give you your speed

and you would basically tell it to play idle,walk,run based on that

and it will blend hopefully well

[steady wolf]

yo can you get into a vc its my first time dooing with the blueprints on unreal and i dont realy understand

[lofty rapids]

not really, but i can open up a project and try to explain it it's not that bad i think let me check tho

[steady wolf]

or can you tell me what blocks i should get and how to arange them

[lofty rapids]

so you want a blend space 1d

this will make it simple

[steady wolf]

i mean you know whats easy so yeah shorre

[lofty rapids]

i mean it will be easier

so right click and search blend space 1d

you need to make this

[steady wolf]

this?

[lofty rapids]

no

in the content drawer

you want to make a new class

[steady wolf]

ohh kk

[lofty rapids]

you'll need to make two class

the blendspace

and the animbp

but first the blendspace

you will see what it does pretty cool

[steady wolf]

this?

[lofty rapids]

yes

[steady wolf]

alr i did it

[lofty rapids]

select the skeleton

[steady wolf]

ok

[lofty rapids]

so you'll see your in there and you got your animations on the bottom right

[steady wolf]

mhm

[lofty rapids]

on the left

under horizontal axis

the maximum axis value

it's set to 100

so this is the blend space goes 0 to 100

but you want it higher like 500-700

i use 600

but your velocity length is going to be big like that

[steady wolf]

alr i did

[lofty rapids]

then find your idle animation on the bottom right and drag it in

drag it all the way to the left at 0.0

[steady wolf]

alr

[lofty rapids]

then find you walk and drag it it in

[steady wolf]

awit

where to put it?

[lofty rapids]

at about 100

[steady wolf]

ok

[lofty rapids]

but this you will mess with later

you can adjust this part to match what you need

[steady wolf]

alr

[lofty rapids]

hold ctrl and preview the blend

see if it looks good

you can also adjust it now

[steady wolf]

it looks good

[lofty rapids]

ok so save that

[steady wolf]

alr

[lofty rapids]

now you got to make animation blueprint

[steady wolf]

alr

[lofty rapids]

so right click, animation, animation blueprint

pick the skeleton

[steady wolf]

okay

[lofty rapids]

so now you need a few things

[steady wolf]

okay

[lofty rapids]

make sure your in the animgraph

which you should be

does it say result on the node ?

[steady wolf]

yes

[lofty rapids]

i mean "output pose"

[steady wolf]

this?

[lofty rapids]

right click and create an state machine

yes that

[steady wolf]

alr i made the machine

[lofty rapids]

are right double click that

you should see entry ?

right click on the graph and add a state

[steady wolf]

alr

[lofty rapids]

call it idle/walk

drag from entry over to the state node

so you got an arrow

[steady wolf]

yes

[lofty rapids]

double click idlewalk

[steady wolf]

k

[lofty rapids]

so now in the bottom right you'll see your blendspace

drag it in there

[steady wolf]

like this?

[lofty rapids]

ok so put it to the left of the output

and in the bottom left create a new variable

a float

name it Speed

[steady wolf]

okay

[lofty rapids]

then plug speed into the blendpase

and the output of the blend space into the output pose

[steady wolf]

lar i did it

[lofty rapids]

so that speed variable is driving this blendspace

that 0 to 600

that is the speed

go on the left dbl click animgraph

and plug that in the to ouput

compile

and you should see him being idle

[steady wolf]

wait the last part whats a dbl

[lofty rapids]

double click

lol

[steady wolf]

oh

[lofty rapids]

my fault i ten to abbrev things

[steady wolf]

np

[lofty rapids]

if he goes idle then you did it correctly

[steady wolf]

so ths is the final thing

[lofty rapids]

if he still in t pose you did something wrong

what does the note say ?

[steady wolf]

result

[lofty rapids]

when you hover over note, what does it say ?

[steady wolf]

yup hes idle

[lofty rapids]

and did you compile ?

ok nice

[steady wolf]

yes

[lofty rapids]

idle is good

now set your variable to 100

he should be walking

this is just a test

[steady wolf]

how do i set the variable to 100 ( sorry my first time

[lofty rapids]

so you created the variable at the bottom left

and now you click on it

and at the right

there is details

so now this is your variable

scroll down

and in default value

change it to 100

he should be walking

[steady wolf]

hes stil idle

[lofty rapids]

show the bps

first the one with the blendpsace

you probably didn't plug the variable in i'm guessing

or somethings not connected

[steady wolf]

like this?

[lofty rapids]

no what is all athat ?

[steady wolf]

in the blendspace

[lofty rapids]

thats fine

you held ctrl and it looked good

leave that fine

you don't have your anim stuff connected

i'm talking about in the anim bp

where you have the blendspace

[steady wolf]

like every thing looks conected

[lofty rapids]

well it's not

because it would show him walking

if you hold ctrl and drag on the blend space, does he start walking ?

[lofty rapids]

show the bps

[lofty rapids]

ok show the whole blend space

[lofty rapids]

looks like you have three keys on the blend space, you only want two

whats the third one ?

[steady wolf]

2 of the same one i missclicken

[fossil vessel]

Hi ppl, Im using a spline with Add spline mesh component to create some tunnels, I have a tunnel section mesh and that is placed all over the spline, but I keep getting this gaps betwen the section meshes, any idea how can I fix it? Already tried making the mesh longer but that doesnt solve the gap issue, just makes the section longer.

[lofty rapids]

and show the value changed ?

[steady wolf]

this?

[lofty rapids]

and he's not moving just idle ?

[steady wolf]

yep just idle

[lofty rapids]

try 500

this should be working at 100 if you set it up right

[steady wolf]

not working

[lofty rapids]

thats weird maybe i missed something but i literally followed through and did the exact same thing and it works np

[lofty rapids]

and this speed is on the animbp right ?

thats weird

[lofty rapids]

why is it purple ?

[steady wolf]

idk it just it

[lofty rapids]

thats probably the issue

[steady wolf]

how do i fix it

[lofty rapids]

i have no idea what you did

[steady wolf]

mee nighter

[lofty rapids]

remake the blendspace

make a new one

and just change the horizontal axis

maximum to 600

and then drag in the stuff

and replace the other one

because for some reason it shows a curve on there

[steady wolf]

like this?

[lofty rapids]

yes

now drag the idle to zero

and the walk to 100

then save

and replace the other one in the animbp

see if the curve comes off

[steady wolf]

stil purple

[lofty rapids]

you'll have to ask in #animation i'm looking into it but i never seen that before

your doing something the wrong way

[steady wolf]

alr bro thanks for youre time

cya

[lofty rapids]

it should look like this

[gentle parcel]

Hello Sourcers. I need help about a Save Data blueprint used in a Character customizing project which manages different slots. Now... all I did was to just rename that blueprint to separate male and female characters slots saves but as result no slot can be found anymore and i don't understand why. Shouldn't a name change get all the references to that automatically updated? I couldn't figure any solution to the issue, I really hope you yours help. Thanks

[lofty rapids]

so you saved to new slots, and now you can't even retrieve from the old one ?

whats the save/load code look like ?

[gentle parcel]

There were some characters presets already created as samples. adding new ones was no problem, the only problem started when I changed the name of one bp. It's kinda complex, I checked whatever was related to that file and I noticed some "Cast to" nodes were still using the old name but even recasting them didn't work. I try to screenshot some

[gentle parcel]

This is the load/save code in the character's customizer BP

[lofty rapids]

and whats it doing nothing ?

[lofty rapids]

show where you call them

are you passing zero to load as index ?

[gentle parcel]

I'm using an old asset I bought years ago and was never updated since 5.2 and the developer basically disappeared so I cannot get support. I've tried to find what actually makes the call to load the slots but I think they named those bps badly...

[gentle parcel]

that line doesn't exist originally, I connected that in one of my attempts to find a solutuion but I unlinked that one now

[lofty rapids]

check if the cast is failing

put a print string on it

did you make the two children of the one ?

or are they seperate bp ?

[gentle parcel]

everything seems separated. I've found this code in the widget where slots are supposed to get loaded and saved

I'll try what you suggested now

[lofty rapids]

a quick print string, check on both save and load

[gentle parcel]

No warnig or error message pops up closing the player but I know that means nothing...

[lofty rapids]

well thats good

but if the cast failed it doesn't automatically error, unless you try to use the value from the cast

[gentle parcel]

Where should I put that string's printer?

I mean... any part in particular?

[lofty rapids]

off of cast failed at the spot where you connected the save and load

[hardy merlin]

Besides Level Blueprint, is there another way to automatically generate functions that can be called from Console?

Ideally something like a component or game mode that can be on multiple maps.

[gentle parcel]

I did it like this and no string message came up

I'll try doing the same in the widget

[lofty rapids]

so the cast isn't failing

put a print string on success

see if the code is actually running

[gentle parcel]

the widget did give the error

damn... I'm hating widgets so much... they are definitely a true pain in the ...😏

So... what's seems happening is the character's editor does communicate with the saved data but the the widget doesn't

and that's why I cannot see any

[lofty rapids]

make sure it's the correct slot name that your saving too, thats why it would be nice to see where you call the save

it would show that

but tbh you can just disconnect it and try SaveSlote

in the savegame event

[gentle parcel]

I've spent the last 4-5 hours searching for that

Those are the only files I renamed adding "FemaleCharacter_" to the original

[lofty rapids]

check the slot name your saving to is the slot name your loading in the wiget

[maiden wadi]

Cheat managers are a common thing for this. I think Exec marked stuff in Controller might also work.

[gentle parcel]

and this is how it looks like the Saved Data file I renamed

[gentle parcel]

it should be because I didn't make any change in there

but at this point I'm sure of nothing

[hardy merlin]

Can cheat manager be derived in blueprint? Can I have more than one at a time?

[maiden wadi]

It can. It's specified in the PlayerController. And I don't think you can have multiple CheatManagers, but they do have... I think extensions? Effectively the same thing as the manager, but you can register multiple.

[hardy merlin]

Thank you

[gentle parcel]

I'm lost, totally. It seems I really can't fix it. I would try that suggestion but I dunno what exactly you meant with that.

All I did was changing that damn BP name... makes me go back to a couple decades ago when I was working with Macromedia Flash and Actionscript... and a single dot put in the wrong place could break an entire project forcing to make it all from scratch. 😩

[tiny tundra]

Quick question. I have a widget being used as part of a BP actor, when I play-in-editor standalone it won’t receive clicks (likewise won’t work in a build - but works just fine in editor, shrug). I’ve done ton of research to address it to no avail. I just need to get it to work right now, so trying a janky alternative method (I can still track cursor movement over the UI, although the widget won’t “see” the cursor. I am making a UI element in the widget “follow” the XY of the cursor, so that works. What I need is an easy way to see if that “follower” is over my button element that I want to click; how can I check if one UI widget is located on top of another? (Short of comparing XY coordinates, which I suspect will be the answer)

[mental trellis]

And plenty of quick spam too, I see.

[tiny tundra]

A thousand pardons

[tiny tundra]

Anyway, irrelevant. I realized I had a solution under my nose - that standalone mode is obviously still detecting my mouse position over a widget, so I can just use that (make sure it’s within x and y coordinates) then just check for a mouse click. Whew.

[sick sky]

i am passing a int value to this macro which is latent
any ideas why i dont have the correct value after the async action got executed ?

i tried using a macro local var instead, but after the async action its fucked up

seems like the macro is 1 monolith and not a standalone graph like a function
meaning the local var is shared

[tulip patio]

Anyone build apk for Android at target API level 34 ?
In my case I got a storage permission notification and quit the game.
At lower target api, my app works but the play store minimum target api level requirement is 34.

[languid sentinel]

Hello, I am currently debugging my level sequence during runtime,
is it possible to make the level sequencer editor playback also got played along when I start playing my level sequence in runtime?
I would like to know when the playback stop and move again

[surreal peak]

Macros have local variables you can create. Try saving it to that.

[surreal peak]

Are you trying to save to the phone or so? Haven't done any mobile stuff in ages but iirc at some point the access to storage got strictly limited.

[tulip patio]

Not saving anything. I actually don't need the external storage. But somehow the manifest file automatically adds that permission. Even after removing that permission.

[surreal peak]

probably best to check #mobile ?

[tiny tundra]

Shown is WidgetA ("unitPopup_world") which contains Widget B ("PositionTrackingButton"). Something occurs which causes Widget B to fire it's function AltClickEvent. I want to AltClickEvent to just fire a specified function on Widget A (it will be different in many cases, as Widget B will exist on many other buttons such as Widget A which is currently holding it). Is there a simple way to do this (or something like it?)

[tiny tundra]

I got something to work but it is far from ideal and I am sure everyone who reads it will curse my name. Basically I will set a boolean on Widget B to TRUE - Widget A's Event Tick will check if that bool is TRUE, reset it to FALSE, and do something unique on itself (Widget A). Sucks but it works for my deadline in a few hours.

I will potentially have a ton of objects doing this at once so I am sure there is a far more elegant solution, but I can slot that in later I am sure.

[remote wasp]

Oh god please don't do that in tick
Just use an event dispatcher

Create event dispatcher in widget B
In widget A Event Construct get the dispatcher from B and bind an event to it

Then when B fire its function you can call the dispatcher, and A will listen and fire the bound event

[tiny tundra]

let me try. I have used event dispatchers before but I am still foggy on how to use them correctly.

[remote wasp]

Think of them like a radio broadcast
The one who has the dispatcher (in this case B) is the radio station with the mic, and "broadcasts" when an event is happening
And all of the other objects that you want to react are "listening" for the broadcast, and do smth when they hear it

[tiny tundra]

Awesome looks like it worked. here's widget B w / Event dispatcher

And here it is being called on Widget A

[remote wasp]

Yep, that's how dispatchers work

[tiny tundra]

Perfect. Thank you!

[remote wasp]

I have a question of my own

I'm making a 2D platformer in Unreal (I know)
I want to have an actor with a tilemap component act as a "damage" tile
It works fine when the player character lands on it, the OnHit triggers correctly
But when the character just walks on the tile, OnHit doesn't trigger

[maiden wadi]

That's odd. Normal Paper2D Character?

[remote wasp]

PaperZD actually

I'm thinking it has to do with the capsule collision position

But if I put it lower then the character sprite floats above the ground

[maiden wadi]

Are the pink and red are two separate components?

[remote wasp]

Yes, the pink platform is just a tilemap put directly in the level
The red tile is an actor with a tilemap component

[maiden wadi]

Odd. I'd expect it to hit then since the capsule is swept moved.

Unsure what you can do short of swapping it to an overlap of a slightly larger collider. Unless you want to go digging into engine source.

There is the other possibility of going the other way and having the character tell the floor actor through an interface or something that it's touching it. Feels odd, but might be better than sticking colliders everywhere.

[full badge]

it only swept horizontally

[remote wasp]

I was thinking about that yeah, but it would mean that the character is constantly checking what's under it

[maiden wadi]

It should still hit the floor though.

[full badge]

the current floor variable from character movement component should help

[full badge]

if shouldn't if the damage component is at the same height as the one he walked off

That makes no logical sense. You're colliding with pink. You move right and you should collide with red. You're stepping off of one and on to another. The fact it doesn't cause collision notifications is an engine bug for sure.

The only time it shouldn't run an on hit is if you roll along the same object. You have to leave that object and return to it for a second hit event. So not every step should cause a hit, but stepping onto it for the first time should.

[full badge]

if you actually step off it it will hit

but from that picture it won't change into falling mode

so it only sweep along the direction you move

which won't hit

[maiden wadi]

He's stepping off of pink and on to red. They're separate components. It should cause a hit event on red.

[full badge]

that's an ue moment

for some reason it only counts if you walk into it

or fall onto it

if the sweep didn't hit it didn't hit

[remote wasp]

Ok what are my options then

[full badge]

get current floor variable from character movement component

and check the hit component

[full badge]

should be a hit result structure in it

[remote wasp]

So there's no way to keep the logic in the tile only? I have to be detecting it from the player?

[full badge]

you can also just simply put a trigger box a little above it

when overlap player do the dmg

but that could cause some problems

[remote wasp]

yeah but I wanted the object to be flexible and have multiple variations in size, which is why I was excited about tilemap component

If I need to adjust the trigger box for each variation that's gonna be a pain

[full badge]

you can write some simple bp to set size depending on the bounding box of the tiles

[remote wasp]

what kind of problems?

[full badge]

like it still triggers if you're not really touching it

[remote wasp]

Oh yeah I see

[full badge]

since the way how triggers work

[full badge]

should be fine if they're like 1cm above the actual thing

[remote wasp]

Alright, thanks for the help

[spice viper]

Does Value Range on a variable not actually clamp despite the description?

[tawny hedge]

I think that only applies when setting the value in the editor, not actual runtime when modified. For that you might need to use the clamp node

[lofty rapids]

thats what the ai says about it "The range just limits what the editor slider allows you to pick"

[astral pilot]

Anyone knows why a level blueprint cannot store a reference a actor in the level?

[desert stream]

https://youtu.be/wrVSeWa7oP8

[frosty heron]

Yes it can

Though you shouldnt use level blueprint if you dont know its limitation.

Level bp cannot communicate with other blueprint class.

[astral pilot]

Hmm If i do the right click to create reference

[frosty heron]

Any gameplay code shouldnt be in level bp.

[astral pilot]

it works, but i cannot create an actor var in level BP and assign an actor to it

[astral pilot]

Be in game mode?

[frosty heron]

Depend on what you want to do. You will place your logic in the appropriate place.

95% of the time is not level bp however.

Outside the scope of very simple code where the context is just that level alone and some simple prototype code, you dont want to use level bp.

[astral pilot]

But do you know why my level bp cant store a ref of a level's actor inside a variable?

[frosty heron]

Your level bp have access to the actor in the level as long they are placed in tbe level.

[astral pilot]

It just keeps saying none

[frosty heron]

Select the actor in the level, right click empty space and you will see the option to drop the reference.

Then you can set that to your variable

[astral pilot]

I can't set it directly from the variable? by using its eyedrop?

[frosty heron]

Don't think so but i will just say drop the level bp all together

What you can do is create an actor

This can be your level manager

Drop it to your level

[frosty heron]

Create var then you can use the drop down

[frosty heron]

Oh well there you go?

[astral pilot]

Doesnt let me pick or use the dropdown to select a actor in the level, could be a bug?

[astral pilot]

It doesnt work though it stays none

[frosty heron]

Don't know but level bp for your game plag is cursed as f

I wont worry about these detail and save your self some time from shooting your own foot.

The moment you need to talk to other bp class you will hit the wall.

If you need a manager for your level, just create an actor bp and drop it to the level. You will be able to use the drop down + communicate with other bp class.

[astral pilot]

Those are just the default inherited variables, I only made 1 Actor var

Meh, Im gonna assume its a bug

[astral pilot]

This works well though, thank you

[frosty heron]

Its a better approach imho. Just place one in the level and when you want to grab a reference to the manager you can just use get actor of class because there should only be one instance of it in the level.

This class is what is called as singleton.

And whats better you can reuse this same manager in another level.

Without repeating the code!

Where your level bp logic cant be applied to another level w.o repeating

[astral pilot]

Doesn't Unreal expect us to use GameMode as the singleton?

[frosty heron]

Game mode is also a singleton, but its responsibility is to define the game mode (rule, etc)

If it make sense to place the logic in game mode then do so by any mean.

But think about something like the world item spawner

[astral pilot]

Level BP is for level specific non gameplay stuff?

[frosty heron]

Or randomizer

I wont say that game mode is the perfect candidate.

[frosty heron]

Its a legacy tool that can be used for quick prototype

[astral pilot]

[wicked surge]

Hello, is it possible to call GetAllActorsOfClass and then get-by-ref from the resulting array? I don't seem to have that option available.

[frosty heron]

Most bp operation is by copy but the copy is the address, so thers no real performance hit.

The actor pointed by the address is still the same.

[wicked surge]

Ok thanks, but I'm confused because I thought I could usually get-by-ref from an array, but like I say, that option doesn't seem available from the array pin on GetAllActorsOfClass

[frosty heron]

The method output an array.

Its an existing method, you dont have a say wether the output returned by value or ref.

You can do that when you define your own function.

[austere orchid]

skill issue

unreal is goat

[surreal peak]

Probably gotta save it to a variable first (:

[sand shore]

An array of pointers doesn’t need a by-ref getter because if you need to modify the thing stored in the array you just set the array element.

The purpose of a by-ref getter with respect to structure arrays is so that you don’t have to Get -> Set Members In Struct -> Set Element — you just Get by-ref -> Set Members.

My guess would be that it doesn’t let you make a pointless by-ref get (as you’re not able to override the pointer in the array easily with reference semantics in BP syntax and maybe not at all)

[polar barn]

Can I make Animated Widget Blueprints Like for example the text on screen scrolls across the screen

[spark steppe]

yes, UMG has it's own sequencer to create all kind of animations

and you can do it procedural if you want to take things like screen resolution into account

[lofty rapids]

bottom bar

animation

[prime stump]

Hi, does the IsA node create a dependency with the ObjectClass?

[prime stump]

Yes, yes it does..

[olive yarrow]

some time between when i went to bed and turned back on my PC my games FPS decided to tank... How do i go about seeing whats suddenly doing the damage?

and it randomly went back to normal... huh...

is this why people use Unity? 😂

[narrow sentinel]

So got an issue where my projectiles aren't hitting the ship, the ship skeletal mesh collision is this and I've added collision boxes on the phyics asset aswell

the projectile collision settings are this

now I would have though because the ship collision has block for projectile settings on and the projectile is of that object type surly the collisions would be recieved etc

[paper gate]

If anyone has a sec I could still use a hand with this. Its driving me nuts that what I'm pretty sure is a super basic operation isnt working. But maybe im missing something idk

[narrow sentinel]

anyone able to help me with my issue please as I can't understand why the projectiles aren't causing collision responses on the things they hit

[olive yarrow]

check root collision/create physical root collision. I hate projectiles, wait until you add them to a pool it gets worse

[narrow sentinel]

so at the moment I'm using a box collision as the projectiel detection for if it hit something

and I can see the box collision is moving with the projectile etc just seems to not be getting destroyed or any component hit events being called

you can see there the full projectile layout and I don't see what can be causing the issue

oh so turns out the root component has to be the thing doing the collision

I always thought that wasn't a hard set rule but it seems to be

[rain warren]

To anybody familiar with StateTrees: How would you go controlling the flow of a StateTree using a bool that is set (and unset) in an outside / actor blueprint?

I'm trying to detect the completion of a turn that is done on a tick function in my character BP in the StateTree, but can't get it to register and control the stateflow properly.

E.G. I want the state to go:

1. Idle
2. Turn to face target
3. Move to target

I don't want the StateTree to move to step 3 until 2 is finished

[frosty heron]

Try #gameplay-ai

[paper gate]

if its just a variable on your actor, just use it as a context value in your transition conditions

or enter conditions mb

[fossil vessel]

Hey peeps, for some reason my skeletal mesh is dissapearing on some angles, any idea what may be causing this? I think I disabled culling just in case, but no luck

[lunar sleet]

Not really bp related, you could try #ue5-general or #animation maybe

[remote wasp]

Hi, I'm making a 2D platformer in Unreal
I have a camera attached to a spring arm on the player, but I'd like to constrain the camera to the X-axis, and not move up and down along the Y axis
Is there a simple way to do that?

Ideally I'd like to avoid detaching the camera and making it follow the player in a tick event

[lofty rapids]

a custom camera actor is best for this

but i think you can constrain it

[faint pasture]

Why do you need an array of pointers by ref?

[lofty rapids]

but actually you would constrain the character to a specific axis

not constrain the camera

but for sure a custom camera is perfect, with interp on tick

[remote wasp]

Yeah unfortunately I think that's the only option

[faint pasture]

that would be the simplest

that's all the spring arm is doing under the hood anyway

just lose the spring arm and in tick, put the camera where you want it to be (in world space)

[remote wasp]

Weird that there isn't an option to constrain the camera to an axis like there is for a character

[faint pasture]

that'd be a bunch of stuff to add to scene components, it's simple enough just to do it yourself.

constraining really only makes sense in the context of physics or movement components

[remote meteor]

actually attaching and tick doesnt have that much of a difference

when you move a component, all child component transform are also updated

movement is on tick

the only thing you save is when you are not moving

[rain warren]

Thanks. I am setting a bool (bRotationComplete) at the end of my rotation process which is done on a tick in the Actor BP. I've added a check for this bool (which is definitely getting set properly) into the conditions for my Rotate state, but the state never advances to the next state (STT_MoveToNode). Can you see any flaws in this setup?

@Robotvirtual , actually nm - your suggestion to put the check on the ENTER condition for the MoveToNode task rather than on the Transition of the FaceNode worked!

[paper gate]

ya thats what I was about to type lol.

[rain warren]

I think my issue was I was forgetting that, although the bool is getting set on a tick, the check that happens within the facenode task only ever happens once regardless, so it would check at the beginning and never again.

[paper gate]

the thing you need to remember with state trees is any nodes that are on the same level all try to happen at the same time, and the tree just picks the first node it CAN enter

[paper gate]

that too possibly

what you wanna do with state trees is either nest the nodes in a way that they ened to step into each other. Or give each one a unique enter condition and the tree will ...well enter, the one that it has "permisison" to

[rain warren]

However, now something weird, the 'facenode' task seems to be ticking itself! When I have debug print in the task you can see the enterstate firing off constantly. Not sure what that's about ...

[paper gate]

in your picture above idk what the enter condition (if there was one) for "move To" was. But it was hitting "face", performing the task and then jumping back up to root. then repeat

[paper gate]

the variable that lets this task leave is being set on tick? Is that a one time operation or is it happening constantly?

[rain warren]

It's one-time, after I verify that the rotation has reached its destination, although there may be some weirdness in that evaluation now that i think about it since it has "tolerance" ...

better context:

Oh wait...

Oh nm, yeah , for some reason my task STT_FaceNode is firing like crazy during the rotation which is weird as I thought tasks were one-and-done unless you specified otherwise.

This is all a headache because I just need a damn smooth rotate node that works like the AI Move To node (ie latent) so I can control the logic flow within the task to wait for the rotation to complete the way my move task waits for the move to complete :/

[paper gate]

they are one and done, the thing is whith state trees is they will ALWAYS bounce around as their conditions update

thats why each node needs clear enter and exit conditions

[rain warren]

Ahh hok

[paper gate]

whats probably happening is your tree enters and goes to "face" begins the operation and is then allowed to leave too early. at which point it says "job done" and goes back to root and loops in on itself

so you need to give it an entry condition that makes it only able to enter once until the job is 100% done. And probably make its transition stament FORCE it to go to move to otherwise it will default back up to the root

[rain warren]

So, basically, my 'Face Node' task will keep firing (on tick) so long as bRotationComplete is FALSE?

[rain warren]

This makes sense! Let me try that.

I'll make a bIsRotating to try to gate the re-entry of the task...

[paper gate]

The basic gist is you probably want something like this

[rain warren]

Yep, it sounds like I'll need 2 conditions with an AND to do this...

[paper gate]

this is one of my nodes in my project. Its got 2 entry conditions to make sure it only enters under specific circumstances. And its exit states can send it to one of two places depending on what happens

BTW @lofty rapids srry to @ you but I saw above you were talking about a camera system thing. Do you think you'd have a second to help with an issue im having with mine?

I think its a pretty simple issue but for some reason its kicking my butt

[faint pasture]

That's the condition to ENTER, leaving is the task being complete, typically

I think bRotationComplete is redundant, or it at least being external is

[lofty rapids]

possibly, whats going on ?

[faint pasture]

You enter FaceNode, and you exit when FaceNode thinks its done

[paper gate]

this is my orignal post

im working on a camera system all the interp and blending stuff works just fine and dandy

but for some reason trying to do a simple. "go to this specific location" ends up with some kind of offset

@lofty rapids ^

[rain warren]

Yeah, my issue is that I need a bool to check when FaceNode is ready to move on since the actual rotation has to happen in a separate actor BP on tick, so I need to check the bool that exists in that BP.

PS - Can anybody explain the difference between State COMPLETED vs State SUCCEEDED here?

[lofty rapids]

do you call this event on tick ?

[paper gate]

compleated = it ended, period

succeeded means it actually succeeded in doing its task

you could end up with a compleated if it failed too

[paper gate]

yes

[paper gate]

this is the main driver of the camera
