@azure smeltu using 1st person?

[azure smelt]

[cursive path]

How can i when attack when i idle when change pose it doesnt repeat animattion

[high ocean]

@azure smeltthrow a fkin cam boon in there and see how that handles the problem. Try it 😄

[azure smelt]

I am using a camera boom

[sand bloom]

Is there a way to use add movement input even if you're calling a function from another actor? Because my character isn't uh moving

[high ocean]

oh...

[sand bloom]

It's constantly printing the string but not doing anything else

[cursive path]

Anyhelp pls need tips

[paper galleon]

I think they have a character you can inherit from. With the rotations resolved

[paper galleon]

You're not helping yourself. You need to show some code. There's no way anyone can magically know what your problem is

[azure smelt]

Yes but it's not ideal

[paper galleon]

Then you have to work out the math to solve your rotation problem yourself. Iirc, in the CMC the gimbal lock is resolved

[orchid garden]

you changing the pose via the animation bp or the character bp?

[azure smelt]

I should be able to resolve this. Plus i plan to have flying characters in my game in time so resolving this gimbal lock will be useful now and then. I appreciate the help 🙂

[paper galleon]

No worries.

[azure smelt]

I should be able to find a resolution online

[glossy egret]

@paper galleon
XD nah epic get the memo an just didnt give a damn.
the varable updates correctly in the player. as told to me by the print string getting the right values.

but when i take that variable and give it to the make damage node it just sends the original value.

so pen is default at 10101 for testing.
i check. players does 10101 damage.
update to value of 2, print screen reads 2 strait out of pen variable
go to test again, does 10101 damage.

well i have to go to work. but thanks for helping. i may just have to do this differently.
because it just doesnt want to work

its possibly an engine bug

[paper galleon]

😅. Maybe. I hope you're able to get it working

[glossy egret]

hopefully. ill try again when i get home

[heady burrow]

In a RTS game, where you are about to place a new building, and you see this "ghost" building that is attached to your mouse, what makes more sense, to have a different actor altogether to show this silhouette or to be the same building with a different style?.

[still swallow]

So, I have a pretty big question.
How do I recreate this system -

https://youtu.be/QcWcqAo4QQY

[paper galleon]

I'd go same actor blueprint with a different material for the mesh

[patent hornet]

still p new to bluprints, trying to have an object look at an animation blueprint

[heady burrow]

thanks, I guess makes it easier

[patent hornet]

this is the set-up i have but seem to be running into a bit of an issue?

any help is appreciated thank u

[paper galleon]

What is the issue. The warning on the node?

[paper galleon]

What does it say?

[patent hornet]

wait lol thats illegible

[paper galleon]

Which blueprint is that?

[patent hornet]

attatched a blueprint to a static mesh

[paper galleon]

Wouldn't work. That node is exclusive to an anim instance

[patent hornet]

ok for sure

[paper galleon]

How'd that even get there. Copy paste?

[patent hornet]

so there's no way to get a static object to follow the location of an anim blueprint then

[paper galleon]

An anim blueprint does not move. It's not an actor.
What are you trying to achieve

[patent hornet]

do u mind if i dm?

[paper galleon]

Nope

[patent hornet]

thank u

[sand bloom]

Does anyone know whether or not I can use add movement input without possessing the character(i'm triggering the function from another blueprint and the values aswell)

for some reason nothing is happening, and i checked the values are being updated, it has values to access it's just.. not doing anything with it. And it's constantly being triggered.

really confused with the node just not doing anything at all

[paper galleon]

You can. I do that for my horse mounting system

[sand bloom]

do you see anything wrong with my function?

I could have sworn it should work

nice to hear you actually can though, just so i'm not crazy

[paper galleon]

Is it in a multiplayer environment?

[sand bloom]

no purely single player

I have a vr pawn in which this all happens

it's basically getting my axis value, vector value, and movement input to my functions inside the character

the character however refuses to move

[paper galleon]

You're calling the movement function before setting that movement variables. I think the order should be reversed

[sand bloom]

that's fair, i figured with it being triggered constantly and therefore updated constantly it should be fine but ill change it rn

yeah that didn't change anything, right now i'm in the am I crazy or should this move stage, so it's kinda rough

my main objective is actually moving it somehow rn

[paper galleon]

I'd pass in the scale value and movement direction directly into the move function rather than create separate variables for them.

Then get rid of the sequence and use the branch directly.

Give me a moment to power up my pc and show you my setup

[sand bloom]

I'm not sure how i'd put it directly inside the function, the reason I created the variables was just so I could actually get those numbers inside the function

Alright ty

I can't get an input to work inside the character so this seemed like the next best thing

[paper galleon]

The variables just create an extra layer of complexity. If the move function is the only use case of the variables, no need to use them in the first place

Editor is taking a while to load

[midnight cove]

Hey does anyone know how would you rotate an fps cam when moving left or right,

[sand bloom]

I hear what you're saying but I don't know any better way of getting them inside the function since it's in another blueprint

alright take your time no rush

[paper galleon]

You use input pins

[sand bloom]

right, but there's no way i'm seeing to get it inside of there because there's no pin to enter it

[paper galleon]

You create them in the move sidestuff itself.

[sand bloom]

ohhh

[paper galleon]

Yup. You understand now?

[sand bloom]

well damn, that's useful for sure

yeah that's great 😄

way more efficient

[paper galleon]

Exactly

[paper galleon]

I don't understand the question. How do you want the cam to rotate

[midnight cove]

like roll slightly to left when moving left

[paper galleon]

@sand bloom , you solved it or do I still send my setup?

[sand bloom]

It's still not doing anything though

I don't know what i'm doing wrong lol

[paper galleon]

Hold on

@sand bloom

[sand bloom]

Thanks I have the same thing as you, but maybe I need to use control rotation's vector instead of camera based i'll try that now

[paper galleon]

You trying to convert enums to string?

[high ocean]

@paper galleonNope 🙂 nvm though, I got it - doh! just need to set the appended string for each iteration. I got it. Thanks anyway! 😄

[sand bloom]

still nothing this is maddening

Thank you for your help though I appreciate it

[paper galleon]

show your setup again

[paper galleon]

No problem. It's nighttime here and only thing left to do is sleep.

[sand bloom]

Here is my setup in the vrpawn

[paper galleon]

remove that check and pass it directly.

[sand bloom]

inside the function

The string is printing

so I know it's working technically

right, i suppose i don't need that old branch anymore

[paper galleon]

Oh, right. Then its a problem from the character referenced itself

[sand bloom]

I made sure to spawn it in my vrpawn so i could make sure i had a good easy reference

I promoted the return value to a variable

and use that as my reference

[paper galleon]

I meant in the blueprint of the referenced character

[sand bloom]

oh

besides the functions the character is empty in the event graph

[paper galleon]

Maybe from the move comp or something. Check movement speed

[sand bloom]

like all it essentially has is the functions

[paper galleon]

max walk speed

[sand bloom]

still at default

[paper galleon]

Hmm weird. Mine works fine.

[sand bloom]

Yeah idk either

[paper galleon]

No movement at all?

[sand bloom]

There's a navmesh volume for the vr that's the only thing left I can think of

yeah 0 movement

[paper galleon]

Is the char ref a regular character?

[sand bloom]

set directly from the pin to upgrade to variable

and the character is a character

So I assume it is

I can use a generic character ref instead though

but everything else to the function works

[paper galleon]

Hold on

do this in testing char blueprint

[sand bloom]

okay

[paper galleon]

and drag that character into the level, run the game and check if it moves

[sand bloom]

yeah it did

which is good

now I just need that but inside the function

[paper galleon]

Yeah. That setup should work. Wait.... why is the scale so small

when spawning, I mean

[sand bloom]

because the character has to be small but regardless of the size it moves with event tick I made sure to try diff sizes

it moves(fast though lol)

I think the issue is my spawned character

it's floating

[paper galleon]

oh no wonder it isn't moving

[sand bloom]

something must be wrong when I spawn it

vs putting it down

yeah idk what's up

what I could try is putting only one in my level and then accessing that for a reference, instead of spawning it

[paper galleon]

If it is floating, gravity isn't affecting it for some reason

[sand bloom]

yeah it's super weird

[paper galleon]

It needs to be grounded to move. Placing a character manually usually ensures its grounded most times.

[sand bloom]

hmm I see

I'll try getting a reference when placed manually right now

[paper galleon]

It will work if placed manually

I tested spawning here too for some reason, it doesn't want to fall

[sand bloom]

wow, I wonder how this is going to work for respawning the character if it dies lol

But for now i'll go and test it

working on the bp rn

[paper galleon]

I found a fix

In the class defaults go to the Pawn section. Select the auto possess ai option to placed in world or spawned

it will fall and should be able to move then

@sand bloom

[sand bloom]

omg

will try spawned again then

oh god

that was the whole issue

thank you, I can't believe I spent hours only for the fix to be this simple

it's actually moving now, I just have to figure out the rotation but this is amazing

thanks man

[paper galleon]

No problem. Glad I was able to help

[sand bloom]

man it works perfect with camera vector's this is awesome I can progress now

[paper galleon]

Great. Kinda disappointed with myself a bit that we spent this long on it. But I'm happy it's working

[sand bloom]

Haha yeah I feel you, i spent hours on all kinds of stuff because i didn't realize this was the issue

[paper galleon]

Alright then. Good luck.

[sand bloom]

thank you

[amber dragon]

does anyone knows how to disable a different character moviment when the enemy catches the player? Because even when I get caught im still able to move around

[sand bloom]

your cast isn't plugged into anything in this screenshot

Maybe you have force on in your movement node?

force can override it afaik

so you want to keep that off

[amber dragon]

i plugged after the animmontage, however it gets a message which cast has to have a valid object

[paper galleon]

You're casting to game mode not character

[amber dragon]

not sure

[sand bloom]

Yeah whenever you cast like this it needs a way to see which object to cast to, it's probably not force

since that's off by default

also yeah you're casting to the gamemode

[amber dragon]

i tried that, but it says it's not valid from player character mode

[paper galleon]

You need a reference to the character first

[amber dragon]

sryy to ask, how can i get this reference?

[paper galleon]

Depends on how you do the catching.

How do you determine if a player has been caught

[amber dragon]

i used a boolean to determine if the player has been caught, than the camera turns to the enemy direction, it plays an animation caught -> fade camera -> open level again

[paper galleon]

How is the Boolean set? I'm looking for angles where the character can be referenced in your blueprint.

[amber dragon]

oh i guess it worked now, because i used cast to thirdpersoncharacter, then reused a get player character from another part of the caught system

[paper galleon]

Yep this is better.

[amber dragon]

@sand bloom @paper galleon thxx for helping

[sand bloom]

I did very little, ozymandias did the work but i'm glad it worked out for you

[paper galleon]

Nah, not really.😅

[trim matrix]

huh, if I have an object and I want to know the class of that object do I just cast it until I get the right one? Isn't there something like c++ myobject->IsA(MyClass)

[frosty goblet]

I know that I am missing something simple... but I am trying to make a title screen in the 3d Sidescroller basic template, but I cannot find anything that will allow me to just pull a camera placed in a level to be the viewport for the title screen. It always spawns the player character. Any advice or direction to a tutorial would be awesome. Thanks!

[spark steppe]

you can use get class to get the actual class of an object, is child of (iirc) to check if its either of class X or a child of class X, and cast to ClassX to test/cast to a specific class

[jade nova]

can anyone help me find a way to do a top down racing game / isometric

i really wanna do it so if u want to help pls dm me

anyone who wants to teach me how to do the blueprints

[pine trellis]

does anyone know how I can get footsteps to play if a character is walking on a wall? the footsteps sounds only work on the floor and not the walls and celiings

this is my code now

[dense pulsar]

Ironically I am also having I very hard time with line traces. Are your footsteps decals or static instances?

Oh nevermind, I read that wrong.

So you want sound to play based on the type of mesh you're walking on right?

Have you tried just using onCollision and checking if the collision object is a wall? Or Overlap?

[pine trellis]

I was thinking trying to use sockets but I cant figure out how to get the from the animation blueprints

[spark steppe]

you are always tracing downwards in world space (which obviously wont hit a wall)

rotate the end vector of your line trace to match the actor x/y rotation and it might be fixed

[pine trellis]

@spark steppe you mean like this ? put a 150 on the x and y?

it only works like that if I am surrounded but if I am outside the vent it wont work

[dense pulsar]

Have you tried doing a multibox trace?

Just fill the circumference of the vent and get an array from that?

On a similar note, anyone have any idea how to get a trace to pick up static instance components? I can trace regular static instances and meshes and but I can't seem to get a hit on any of the components I'm trying to get.

[dense pulsar]

I basically have an instance that spawns HISM of its components and I'm trying to trace those.

hi everyone need some help as i am a noob so the issue is i want to create a lobby for matchmaking but cant find a proper guide or path to start can any one point me in the right direction

[lunar nest]

You're casting the player character twice, to two different classes.

I think one cast should be from GetPlayerCharacter, while the other should be from TryGetPawnOwner

[sudden nimbus]

i dunno, what are you doing with those graph points

[ornate trail]

proc gen points, the onPaint is just for debugging but would rather build this event driven, just not sure how

[earnest tangle]

I'm not quite sure what you mean by "event driven" in this context

How would you like that to work?

[sudden nimbus]

I dunno I've never done procedural stuff. But if it keeps the result more than a frame and you only change it so often, then yeah do event driven.

to answer your original Q: yeah just "push the data on event instead of every tick" :-)

[trim matrix]

• Question * So I am trying to add combination of buttons to my input bindings but as far as I know you can add only one button to this? I want to activate this for example when player presses dpad and trigger etc.

[sudden nimbus]

does not support sequences of buttons or multiple nonmodifier keys simultaneously as far as I know

you can handle it at a higher level though, keeping track of whether both buttons have been pressed

[trim matrix]

@sudden nimbus That's a great solution!

[ornate trail]

usually this would go in the player controller afaik, if button 1 and button2 etc..

[fallen glade]

can someone have a look at this please? I have a simple mesh (1) that for testing reasons I scale (1,2,2) and in game the collision mesh is not stretching to accommodate this new scale? never happened before

[ornate trail]

unreal stretches collision for you ? 👀

idk any better but other engines I just recreate the collision

[fallen glade]

Yes? I'm i having a stroke ?

[ornate trail]

lol, no I just dont know the engine. Im used to scaling collision causing physics issues

[fallen glade]

It's like the un game collisione is scaled to 222 instead

[fiery glen]

is this collision capsule part of the static mesh or part of the blueprint?

[fallen glade]

Static mesh

Same result if i place it in gam and scale it normally

[fiery glen]

yeah, weird

I'm seeing an old bug report about this

[earnest tangle]

Scaling colliders is definitely fucky in various ways, sometimes it doesn't update when visuals update etc.

It works sometimes and if you do everything right

[fallen glade]

Ok so it should work

only a problem with capsule collision..... I guess I'm using box :/

[rain egret]

i have the case of the classic "wont move forward if look down" forward axis works with W/ S and gamepad stick up/ down.
now the problem only occures when i use the gamepad option here, i added a print to check the axis and in both cases i am getting 1 and -1

[worthy tendon]

so for some reason when you use gamepad and look down it doesn't move? but it moves with keyboard?

[rain egret]

exactly

heres a video of it

first i tried using the gamepad and then the keys

[worthy tendon]

do you have different events for gamepad inputs?

[stray rain]

now I am not sure 100% but if you have a movement component on your actor you can get the "get actor forward vector" node and the "get actor right vector" node so you dont need anything else when plugin into the world direction of your "Add movement input"

(noob here so maybe someone else knows better haha)

[candid nest]

hey guys i have a problem my ai shoots when he sees me i want to make shoot him when he equip gun in hand

[stray rain]

you know how long it takes for him to take out the gun, just put a "delay" before the shooting event?

[rain egret]

well this is the thirdperson blueprint, using your option would have the character turn in a circle if i press right.

[candid nest]

i did it but he used that delay for shooting like i put a 1 sec delay so he shoots me after every 1 sec

[rain egret]

no i dont

[stray rain]

well put like a 5 sec delay then?

[candid nest]

so he will shoot after every 5 sec like i put a delay he fire then take a rest of 5 sec then shoot

[stray rain]

I mean not after every shot, I mean when he sees you, you imediately go to the shooting event right?

[candid nest]

actually he roam when he see me he come closer and then shoot me but if i am closer and he sees me then this problem occurs

[stray rain]

would need blueprint to judge

[candid nest]

okay

https://blueprintue.com/blueprint/2ft_15xt/

go to this and go to on hunt is the place were he shoots me

[stray rain]

I would create an event for "Equip Weapon" and have a delay there and then go to the "AIfire" event after the "equip Weapon" event has been completed

[worthy tendon]

if you create logic and rules for your player like how many times he can shoot, with what accuracy and fire rate, it will be easier to make your AI use the existing logic for shooting. that is possible with some good blueprint, but it will be hard to do if everything in your blueprint is coupled together

[burnt grove]

Erm, how do I connect to my dedicated server by IP? open IP or the blueprint node Open with IP as the map name doesn't seem to work

[candid nest]

i added there not working ai is equping gun late but fire is on

[orchid star]

@burnt grove you also need to put in port

open 111.111.11.1:17777

[burnt grove]

7777 or 17777?

[orchid star]

unreal default is 17777 if you are in editor

[burnt grove]

ah

mm nope

I get this after calling open 86.126.139.126:7777 (the dedicated server should be running on 7777 right?)

Feedback on my item respawn script?

Handles stuff like respawning berries on bushes and pickable items like mushrooms

Although I should probably move most of the interact logic to the respawn function

[worthy tendon]

if pickup destroys pickable actors then you can't get pickable actors in timer again. it will return empty.

[trim matrix]

is that a problem though?

If its empty it simply won't loop over elements

[worthy tendon]

I don't understand why you have that timer for?

[trim matrix]

https://gyazo.com/1b4588015e5c8d0be6473492a4be0985

Multiple items to respawn

lets say I have a bush with 3 berries

I pick up all

I want them to grow out one at a time every x seconds

[trim matrix]

Think it makes sense, but there might be better ways

[orchid star]

if you are controlling all of them from one actor

it gets reset on every pickup I assume

you either fire multiple timers or handle them seperately

[trim matrix]

Nah, because of the "fullyRespawned"

wait, lemme pop up screenshare

in #lounge

voice chat

wait cant share screen here why

[worthy tendon]

what is pickable actors? is it fruits? or the bush?!

[orchid star]

I think they mentioned something about getting a permission first to be able to stream your screen

[worthy tendon]

the bush should handle respawning fruits by itself.

[trim matrix]

well thats what it does

[orchid star]

the thing is fully respawned is handled if all of them are available right

so if you pick up two

second pick up will reset the timer from start

so they will spawn at the same time

whatever you do with this current setup

[rapid robin]

Hi Folks, is there a way I can get all actors in a certain radius in just blueprints (without putting a collision sphere around the actor)? I swear I've used a GetAllActorsInRadius node before, but guess that might have been a custom one?

[random quail]

if you have some custom shape then only getallactors and testing their location with your shape

will be quite slow so better not call too often

[rapid robin]

Thanks @random quail A radius would be fine, so you think best to just slap in a sphere collider and then get all overlapping actors? I'm cool doing it every couple of seconds or so, so not too concerned about speed.

[random quail]

works too, an actor component inheriting spherecomponent with some logic about overlap tracking / storing things inside

[rapid robin]

I'm just confused that I can't find the node GetAllActorsInRadius, as, like I said, I'm sure I used it previously 🤔

[random quail]

doesn't seem to be an engine node

[rapid robin]

Cool, yeah must have been a custom project-specific one then. Thanks!

[dusky topaz]

So I am trying to set up a camera actor to capture a screenshot with an editor event. The event works, it changes the view target to the camera, and takes a screenshot, but the screenshot is taken from the original viewport camera despite it swapping. Anyone have any idea how to do this?

Here's the blueprint I've got currently

disregard that the target blend is disconnected, I was just trying if it actually made a difference

[atomic salmon]

@dusky topazdid you try to use a small Delay?

[dusky topaz]

Delay oddly enough seems to make the time it is in the correct camera shorter

[atomic salmon]

The one at the bottom of the screen shot node?

Or just adding a Delay before that node?

[dusky topaz]

Both

Or rather, the delay in the screenshot node does nothing, and a delay before it breaks the entire operation

[atomic salmon]

And there is nothing switching back the camera after the screenshot? Or?

[dusky topaz]

Nothing in the blueprint, no, it just does it automatically

[atomic salmon]

you may try delaying the switch back because I am pretty sure the screenshot is taken asynchronously and it may have switched back to the original camera before it is recorded. Would need to check the source code to verify that, but a quick test may confirm it.

[pine trellis]

does anyone know how to get the down vector of an actor? I see up, forward and right but no down and I am trying to use this fix

[dusky topaz]

Another oddity with this situation is that it gives me two notifications that a screenshot has been taken every time I press the button, but the actual event is only called once

[supple dome]

down is up * -1

[frail inlet]

do blueprint perform the same as c++?

better, worse?

Anyone here that has made a stats/levels system that could assist me a bit?

[maiden wadi]

@trim matrix Possibly. What are you looking for?

[trim matrix]

@maiden wadi hop in voice?

[trim matrix]

👀

should I use a loop or is this fine? lol

[earnest tangle]

That seems fine to me. A loop wouldn't help because delays don't really play nice with those

You could use a timer which could be a bit cleaner, but if you only have three delays chained like that, it's not really that big of a deal - but if it's more than that, then a timer based system would probably be better

also worth noting is that if you for some reason need to abort or restart your delay chain, that wouldn't work... with a timer you could do it

[spark steppe]

as an alternative a timeline would work, too. just got to floor the result (still the timeline would be more cpu demanding, but guess its negligible)

[brazen pike]

Hello. I am trying to make a map that is toggled by the M key and shows the player location on it. I found that I need to get the location of the player, divide X and Y values by the size of the level in-game then times those values by the size of the image of the map. I found that my values of the level size were innacurate which ruins the entire concept as the placement is all wrong and the player icon moves faster than it should....

Is there any way to find the size of my level accurately if the level isn't a perfect square/rectangle?

Here is my level for reference. Its very large.

[orchid garden]

what i did was got the landscape resolution & scale and mutliplied those values to get the landscape size, then for placing markers for the actors on the map I did this:

landscape X & Y are the position values of the landscape

Is there some kind of node that takes a number like 24178 and outputs it as 5 different numbers one for each place 2 4 1 7 and 8 and a way to do the opposite? Or some help with picking out search terms so I can figure it out?

[brazen pike]

Ah that's super interesting i'll give it a try thanks

[orchid garden]

it comes out pretty close to the actual position, give or take a pixel:

[split cosmos]

hello begineer here. i am trying to make it so when i look at a block it gets highlighted and not highlighted when im not looking at it. I have the highlight mat and i made this basic trace. How do i make it so it stops getting highlighted when im not looking at the cube? i cant figure it out

[orchid star]

@split cosmos What I did in similiar situation was

[orchid garden]

and incase your curious how i did the gps cords for the map:

[orchid star]

that I started looping every 1 second on the highlighted object to stop highlighting

so if it was not colliding

highlight would gone 1 sec later

[split cosmos]

yeah i was thinking that as well but wouldnt that cause performance issues? i feel like theres a more elegant solution

if its every second it will look really sloppy though

[fast blaze]

hello all what will be the best option to track the angle of the stick for the combo tricks in a game, for example I move stick down and next to the left for one quick motion. Now I do branch when move down is true, after moving to the left, but how can I track full movement of the stick? thx

[orchid star]

well you use tick anyways so

😄

[split cosmos]

fair enough 😄

[orchid star]

also you are casting constanlty

[split cosmos]

yup

[orchid star]

what you can do is store the hit result

and stop highlighting just before setting the new variable

you can even check for if it is the same actor, that way you wouldnt need to constantly call set render custom depth on an already highlighted actor

[trim matrix]

kk got a basic experience system working, its trash but it'll have to do xD

[split cosmos]

ty

[split cosmos]

how would i do this? im really a noob to game making in general

[trim matrix]

There is actually a really good tutorial on this @split cosmos

https://www.youtube.com/watch?v=ctToub0bwrA

[orchid star]

Trace > Check If Hit >
True : Check LastHit equals Currenthit >
True: Do nothing
False: Stophighlighting Lasthit > Set Current Hit as Last Hit > Highlight LastHit
False : Stop Highlighting LastHit > Remove reference to LastHit

[loud badge]

Hello there!
can someone tell me which is the proper way to configure an actor with collision box as root component and a child static mesh with physics enabled?
I am getting weird behaviors, for instance:

Having simulate physics only on mesh -> the location of the collision box doesn't update location together with the world location of the mesh.
Having simulate physics both on the mesh and collision box -> after pushing the mesh a little bit, sometimes the actor disappears from the world.

Note: I have overlap all dynamic for the collision box and blockalldynamic for the mesh as collision settings.
This might be really simple, but I am getting so frustrated, i've been on this for like 2 days already :/

[lament ginkgo]

Hey, question - I have a trigger with an onbeginoverlap event, but I noticed if you spawn a player IN that trigger, it doesn't fire off the event. Is there a way to ensure the event will trigger if someone spawns there?

[brazen pike]

By resolution, you mean "overall resolution (Verts)"? Because I have input everything exactly as you did it, and it seems to not work properly although this is the closest I've ever had it working

It seems to be offset by about -330 X and -20 Y when I start and when I move my player icon does not follow properly

[orchid garden]

I might also add my landscape image that you saw on my map picture - I took a snippet of the landscape from top down view in unreal engine, and sized the image itself to the edges of the actual landscape.

[brazen pike]

Ah yeah that might be my problem, my image is not the entire map

[orchid garden]

make sure the X & Y values for the two vars for landscape are also set to the X/Y location of the landscape

[fringe flame]

when i rotate my character his face won't change

if i rotate to left and i press w he won't forward but right

[orchid garden]

if your using a cropped image you'd need to adjust the X&Y values and the landscape resolution values to make it fit properly, which might take you abit of math.

[brazen pike]

Oh man I'm so bad at math

[orchid garden]

whats the concept of how your map should work in your project?

[brazen pike]

As the player moves, the icon will show where they are located. Super simple. But the problem is my level is huge and the landscape extends well past where the actual playable area is since it needs to look like a normal forest, so the in-game map would be a tiny area in the middle of a huge window... so I zoomed in the camera.

I've placed two reference cubes at the corners of where I estimate the map's edges are. Hopefully by finding the difference between them I can get the proper map size

This has not worked

[orchid star]

what I think you can do is:

use your reference cubes on the map

yes

but handle the calculation via lerp

lets say

-10000 <> - 10000 top left
10000 <> 10000 bottom right

Those are X and Y in order

so if your player is in lets say 4500, 5000

Lerp(4500, -10000, 10000)
Lerp(5000, -10000, 10000)

you get the positon on X , Y between 0..1

after that its about converting this lerped value reversed to your map size

as for the zoom, it gets a bit tricky

you can use materials to do the trick

[brazen pike]

Materials?

[orchid star]

you make an UI material

and put your map texture in it

and manipulate it with parameters to zoom in / out

I think you can use text coords to zoom in out

to specify where to zoom

Im not sure how at the moment

but you can find a solution to that once you get there

in our game we use this plugin : https://www.unrealengine.com/marketplace/en-US/product/pro-hud-pack

this doesn`t include a full map

but a bit of work did the trick

it has mini map with always centered player

all you need to figure out is make it show up on bigger area

and figure out a way to get rid of centering

also it had no panning so we added panning as well

although problem with this is(Im not exactly sure) it specifically tells you to use 4096x4096 texture size

I havent tried it yet if it would work on 8k for more detail

as we also have a big map

[orchid garden]

thats why i did the resolution scaling bit @orchid star so i could use a 2k, 4k, 8k or even a 16k map for it.

[orchid star]

I meant the texture

the plugin might be using 4096 as hard reference point

so it might not work with others unless you tinker with it

[orchid garden]

texture size doesn't matter with the map, just as long as its the same dimensions as the landscape , so i could use a 1024, 2048, or even 4096 squared sense my landscape is square.

[orchid star]

you dont need to match it with the map as well

I was talking about the plugin link I posted above

[orchid garden]

with how my code works, yep i do 😉

[orchid star]

oh

[orchid garden]

so i.e. if my map is 2048x2048, as long as my map image is square, then even a 256x256 image would work on it.

but its the full world, not just a section like what @brazen pike in trying to do

@orchid star do have to say though, Piontek does make some really nice hud packages, i have a few of his kits 🙂

[orchid star]

well me too but I really dont like the way they implement the UI

they use Sizeboxes everywhere

padding as well

[nova jasper]

i hope this is the right chat to ask this. Is it possible to change the roll of a spline? like banking a turn of a roller coaster that was made along a spline?

[orchid star]

@orchid garden btw if you encountered the problems about sizeboxes I talked about, do you know a way to bypass those

[orchid garden]

yeah like his buttons, but you can always remake them 🙂

[orchid star]

like is there a magic option to make it work within unreal to match whatever resolution to

1920 1080

god I hope not, if there is it means I wasted too many time on UI implementing

[orchid garden]

um... i'd have to open my other project... just a sec...

[maiden wadi]

Making what match the resolution?

[orchid star]

lets say I used mostly sizeboxes

fixed sizes

but it looks great on 1920 1080

[orchid garden]

i used safezone and sizeboxes for hud scaling, but my hud is broken up into multiple sections and anchored to specific locations to keep the parts in place.

[orchid star]

the moment you switch to different resolution

it will be screwed as it had fixed pixel size, pixel padding

what I meant by matching the resolution is this

if I said 100x100 on 1920x 1080

3840x2160

so 100x100 becomes 200x200

[brazen pike]

Alright thank you, I'm gonna see if I can get this working tomorrow.

[maiden wadi]

Most UI does this automatically with Canvas panels.

[orchid star]

Most UI is kind of not enough tho

[orchid garden]

its all scaled according to the screen size

[orchid star]

IF you worked with UIs deeply

you would see what im going with this

creating a main layout is easy

just use anchors on canvas

the problem comes to you

when you go nested widgets

vertical boxes lists / grids

If I want to create a bit of space between two elements on a vertical box

sure I can use 5pixel padding

it wouldnt look odd

[orchid garden]

on mine thats dependant of actual screen resolutions.

[orchid star]

but most of the time you have to use FILL option to specify

it means you cant make the space with simple

5 button to padding

you need to create a spacer

calculate it

[orchid garden]

your talking like this:

[orchid star]

yes

we have a similiar menu as well

nice one btw 👍

[orchid garden]

as long as its working with actual screen resolutions it works fine, and for widescreens it does this:

[orchid star]

let me check ours

how did you handle the size of the itemslots

[orchid garden]

fullscreen at 1080 looks like:

[orchid star]

I used 100x100 fixed size

[orchid garden]

my panels use canvas panels with fixed locations/sizes insize a safezone.

[orchid star]

hmm what is safe zone let me chcek

[orchid garden]

now i've heard mixed statements about safe zone, but in my case it seems to be working for both ineditor and game play for making sure things stay scaled properly.

[orchid star]

this is ours

[orchid garden]

looks like a good layout

[orchid star]

still not sure what the safe zone is

does it just stop your elements from leaving the screen

[orchid garden]

https://docs.unrealengine.com/4.26/en-US/InteractiveExperiences/UMG/UserGuide/UMGSafeZones/

[orchid star]

basically a scale box alternative

kinda nice

[orchid garden]

yes and no

scale boxes work abit differently

now mind you my huds use widget elements to give those end results too:

each panel is basically its own widget.

those i could stick inside scale boxes and everything would scale uniformly, but if you had multiples in a single scale box you could end up with some odd results.

i.e. overlapping panels

[orchid star]

thank you for explaining

I will tinker around it

[orchid garden]

i pulled apart alot of different projects to see how they built their ui's, it was defiantly a good learning experience

even the UE examples - the complete RPG and the old 'ShooterGame' examples.

idk if its still available, doesn't seem to appear in the 'learning' area anymore but here's the market link for the old shooter game one:
https://marketplace-website-node-launcher-prod.ol.epicgames.com/ue/marketplace/en-US/product/shooter-game

oh there it goes, guess it only loaded half the page when i clicked on 'learn' lol.... it shows under 'games'.

[orchid star]

thanks !

[hearty gazelle]

Hey guys, is there a way to access a widget blueprint through the gamemode blueprint?

[orchid garden]

get the actor its attached to then access the widget via that?

[hearty gazelle]

So then via this?

[orchid garden]

or... when you setup the widget on the actor - set a reference in game mode to the widget?

[hearty gazelle]

So I set the variable here

Then did this

But its saying that NewVar _0 is null

[quartz pawn]

hi

so I have a widget

and I am trying to create that widget

but how do I pass variables to that widget

like the image above?

[gritty elm]

create a variable inside your widget, and mark as expose on spawn and instance editable

[gentle drum]

can someone help me ? Trying to adapt a social system to SGK. I do not want to pull player list from the data table. I am want to pull player name from saved slot . As you can see by my screen shot i need to finish the logic. How could i move forward with such a thing?
as you can see above my load from slot was the logic that came with the social system. Just want the same function but not use the data table but the slot

I wouldn't mind using the data table provided by the demo. Just have yet to be able to figure out how to allow a player through widget update their name from text slot and onto update data table "player list"
This is so simple to most i assume but by my name "Learning to Game" this issue is owning me

Bet for some of you this is a no brainer but been struggling with this for days

[maiden wadi]

@gentle drum What exactly is the Datatable?

[gentle drum]

@maiden wadi thank you for a quick reply . Let me take a screenshot

that's all that's in the data table.

[maiden wadi]

In general, this isn't how you use Datatables. Datatables are meant for static game data that isn't getting changed at runtime.

Like for instance, a classic use case is an inventory item datatable. You'd have a list of items, their icons, stats, meshes, etc. And you could look this up easily with a key. But changing datatables at runtime really isn't a great idea.

[gentle drum]

so i have been trying to do something that's impossible 😩

[azure smelt]

Hey good people, can someone help me out with correcting some blueprint nodes? I implemented some Quaternion code to disable the Gimbal lock. Basically the BP nodes are intended for a pawn, but i need it to work for a character, I read in the comments of the tutorial i was watching that i need to rotate the controller as well as the character, and that i need to remove ticks from camera and Movement Comp. Anyways what can i do to get the character and controller to rotate?

[gentle drum]

I don't know a lot but am learning very fast. I just want the players to be able to update their SocialName

[gentle drum]

How would you do it @maiden wadi

like the easy method

[maiden wadi]

Really depends on your game style. Most times you just keep this information in a Savegame file on the server. Or keep it locally and let clients update it to server for replication at game start/namechange.

[gentle drum]

as you can see by my first screenshot. I tried pulling from savegame slot but dont know the logic to complete it

[runic parrot]

Hi! one question, if you have multiple camera views on your game (one for X situation, another one for Y situation and etc) would you rather have all in the same PlayerController or have a diferent one for each situation and change them accordingly?

[gentle drum]

@maiden wadi see?

[ripe tiger]

Is there some kind of node that is a foreachloop but for a range of the values in the array? Or do I need to create a new macro for it?

[azure smelt]

I would only use the player controller for changing camera angles of the main player, or if they have a power that involves "Remote Viewing" Other wise i would have a different arrangement, like for a security camera.

[orchid garden]

https://learn.unrealengine.com/course/3762545

pretty good course for teaching you the saving and loading routine

https://marketplace-website-node-launcher-prod.ol.epicgames.com/ue/marketplace/en-US/product/blueprint-runtime-saving-and-loading

just a thought, might help you @gentle drum

[runic parrot]

it's more like a mobile game where you build your city (one view) and then you can go and explore the world (another view) and figth creeps (another view)

[limber finch]

Can anyone think of any reason this wouldn't work?

[orchid garden]

your muti-camera thing you asked about, you could use one camera, and reposition it to the capsule component for X & Y situations

[limber finch]

The cast keeps failing, and it was working perfectly fine earlier

[gentle drum]

@orchid garden yup did this one . Thank you for the advice. Always welcome.

[ripe tiger]

I figured it out, you use a for loop setting the first and last index as the range and then use the index to get what you want out of the array.

[maiden wadi]

@ripe tigerEr.. That's exactly what a ForEach loop is?

@gentle drumI would strongly recommend learning some core singleplayer elements for a while. Multiplayer is complicated. This is doubly true if you have no C++ experience or the intention to get it. Blueprint will severely limit you. Specially for things like this.

[gritty elm]

so you want to iterate over the loop in specific range?, you can make a branch condition from array index, for example if array index is >= and <= anyvalue, then run loop

[gentle drum]

@maiden wadi The thing about this is just trying to save and recall a string value right?

actually edit ,save , call string "SocialName" the mulitplayer aspect is already taken care of by the system i purchased

[orchid garden]

couldn't you just use this to find the item in the array?

[gentle drum]

@orchid garden thank going to try it

[orchid garden]

oh sry that was about the people talking about foreach to find a item in array

[spark steppe]

that will still iterate over everything, you could use a for loop with break and connect the false branch to the break of the for loop

[maiden wadi]

@gentle drum You load data from the local machine via a string and user ID. Most games leave the ID zero and just use strings unless they have a profile system set up. If this savegame is on the client, run it there and then RPC your data. If it's on the server, just get it from there, RPC a string name if you need to. Without understanding what exactly it is you're trying to implement, it's hard to help.

[gritty elm]

@ripe tiger yes you can also use break, this save performance

[spark steppe]

yea, doesn't look nice but can make a difference in runtime for large arrays

[orchid garden]

isn't that basically what 'Find' does? goes through the array till it finds the item then breaks returning the index?

[spark steppe]

yea, if you know what you are searching for

but didn't sound like that his code knows that, but for a specific range i would also use some normal for loop actually

[orchid garden]

well that just confused the heck out of me, how can you search for something in a array if you don't know what your searching for in the first place?

[worthy tendon]

maybe the search pattern is more complicated than just checking if it contains a string.

[spark steppe]

he asked for a specific range of the array, not for specific item of the array

[orchid garden]

so you find the first instance and the last instance to get the range? idk, perhaps my array usage is a little more strict.

[restive token]

I have a variable referencing an actor (camera).

Anyone know why "change view target with blend" from that variable to the player would clear that variable?

If I change from that camera to the player character using that node, the variable gets cleared and I cant change back to it

[spark steppe]

does the camera still exist in the world after you changed view target?

[urban solar]

Anyone know how to fix invalid additive animation type?

[ripe tiger]

no a for each loop does it for every value in the array this is for a specific set of values in the array. if you have an array of 1000 different items then a foreachloop will output all of them. a specific range means being able to specify which ones to output like 200-300 for example.

[little path]

I am looking to build an Editor Utility using blueprints, that would allow for rapid prototyping of maps on a square grid. I want to be able to select squares on a grid and decide what to spawn on them on BeginPlay is this feasible with blueprints?

[ripe tiger]

This is how I did it and it works great. In fact it almost feels like that might be what the outgoing index pin is for... although I presume there will be other uses for it.

[trim matrix]

how do I force the mouse cursor?

whenever I click its just gone lol

[humble panther]

Hi, cant figure it out from google, docs and ytb so asking for help. I am doing local multiplayer game for two players (but extendable solution would be better) and i want to store for each player how many times he hit someone and how many times he got hitted and respawned. Where should i store this score and what i need to make it work? I tried saving it to player state but i dont know how to get/set it or call an custom event from pawn. Or if there is a better solution.

[trim matrix]

store it in the gamemode bp?

and maybe use a custom event?

[humble panther]

Ah, i didnt cast it to my player state bp, so i could not access the custom events. Thanks for help.

[azure smelt]

Hello good people, i obtained some blueprints for altering the camera's pitch settings. It works fine, except i want to be able to use the values of "View Pitch Max" and "View Pitch Min" that are found in the details panel of my "Camera Manager BP" please help, how can i reference these variables through BP nodes?

[white field]

is it possible to nativize a single bp even if it references other bp or is referenced by other bp? e,g, do you need to nativize all linked bp?

[trim matrix]

Is there a function for rounding numbers to the nearest desired value? I need to round to every 500 for my float, am I jsut supposed to write a function to do that?

[short lion]

anyone know if "client play camera shake" has been removed from unreal? Keep in mind I'm dragging it off of the player controller and it doesn't seem to be showing

[wet patrol]

Do you guys know how I would come to make a crouch/prone system? Crouch, Crouch to Stand, Prone and Prone to Stand. I have anim montages to play for Prone and Prone to Stand

[vapid ibex]

Guys, any idea on how to implement a snake-like or centipede-like locomotion for a pawn?
Basically the snake's head is turned in the direction it wants to go, and the body needs to follow the path that the head took. Assume the body is a skeletal mesh, though maybe doing it with segmented static meshes will be cheaper?

[trim matrix]

@wet patrol Make a custom enum with all the movement states you want. Then set your crouch input to switch between those states.

node is called switch on - "enum variable name"

[wet patrol]

So i'm trying to make everything inside the character without any outside input by branching. I've been trying and this is what I've came up so far. Only problem is Prone to Stand doesn't set the normal collision and this only works in stand alone but feel like it'd be easy to replicate when I find what the problem is. Any help?

[sonic pine]

Hiho, I need some advice.
I am currently considering how to build up the skill mechanics in a meaningful way. My idea was to build a SkillFunction library in which I have a function for every skill. In this function, all important data from the data table are processed, for example:
Name: Fireball
DMG type: magical
MagicDMG: 64
Current Skill LV: 0
Max Skill LV: 10
Mana cost: -15
Cooldown: 12s

I need all of this data in different blueprints. I need the name, the description, the current and max SkillLV in Skilltree, the magicDMG, cooldown, mana costs, I need in the SkillActor_BP and so on.

Now my questions about this are:

1. Is a library really a good one?
2. The skill processing such as MagicDMG + Weapon DMG + CharacterBase DMG, should I process this in the Character Stats, the SkillActor_BP or already in the library?
3. How do I transfer the functions to the skill tree?

Appendix to 3.
A passive skill changes the basic values ​​of the character as soon as he is skilled, how does the skill tree know that there is a new skill behind the button?

I can change the Icon, Discription and so on but if im skilling the skill the same function will start

[odd plume]

What does this mean? That the event dispatcher is wrong and the signature does not match?

[short lion]

It seems like you have a duplicate of your custom event that you are binding to that does not match the binding. As you can see your custom event is OnUserSettingsUpdated_Event_0 while the binding is asking for just OnUserSettingsUpdated

[odd plume]

Tried changing it, no dice

[dark crow]

Right click the custom event and Refresh

[last siren]

Did I miss something with BP_Sky_Sphere or is it only written for equatorial locations when using "Colors Determined By Sun Position" (and then the direciton light coming from say BP_SunPosition for a date+time)?
It seems it wants "Sun Height" to be near -1 for a dark sky but this never happens as the latitude moves further away, and it seems to overwrite any value I set myself.

[vapid ibex]

No one?

[woeful pelican]

I know a video that does a classic Snake implementation but that's it

[shut hinge]

can you put box collision triggers inside of each other if they are set to fire from custom events with booleans?. Because I'm having an input issue, the custom events only seen to work once with the mouse and to get them to fire the custom events again with the mouse I have to walk out of the triggers and walk back in them again. But that's not how I want it to fire, for when the boolean has been activated, the trigger should automatically fire off the custom event when I press the mouse button option again when inside of the triggers as I'm doing dialog menu options from the widget using the mouse buttons. I'm puzzled as to why the custom events don't always want to fire

[thorn veldt]

Hello! Whenever I try to cook my project, this error pops up. Any idea on how to fix it?

[rapid robin]

Seems like it doesn't like your struct. Maybe it lives in a non project folder, or it got renamed/moved and the redirects got messed up, or maybe there's something deprecated there. You could right click on the folder and select Fixup Redirects. Or you could just try remaking the struct and wiring it up in your widget again and it might just start working.

[silk hinge]

Hey there i'm having an issu with that and, I didnt find any ansers yet every time when I try acces variable from another actor into my character blueprint in just never work. Is there any way to do that ?

This Ant Bp is an AI enemy and I'm trying to get his health to be abble to trigger some code ^^ Into the UE4 char blueprint
(variable is public and instance editable)

[spark steppe]

where is the Ant BP variable set?

[thorn veldt]

Fixup Redirects fixed it. Thanks a lot!

[silk hinge]

Into the Ant blueprint reference

So i get the actor with a variable from UE4 Char and get the variable "health" linked to this actor

[spark steppe]

does it throw an error?

[silk hinge]

yeah failed to read proprely the branch its plugged to nothing else

[spark steppe]

did you ever set a value for ant bp?

because it sounds like you aren't doing that, which is why it fails

[silk hinge]

hum nope I just get the value without setting it ever into the UE4 char BP

so before trying to get any variable set up into the Ant BP I would have to set "Ant BP" by calling and seting it somewhere into UE4 char BP ? 🙂

[spark steppe]

yes, it needs a reference to the actual actor

so i guess you have that ant which is AI and a "normal" character which is the player?

and the player should be able to interact with the ant

[silk hinge]

exact 😄
I do have ant actor variable into UE4 char but never tryed to set the Ant variable before trying to get any of the Ant variable
I will try that on tommorow its really late here, Ty for the help 🙂

[spark steppe]

yea, your character needs a valid reference to the actual ant actor, which you can only set on runtime

theres probably some tutorials on youtube about how to integrate entity interaction

[silk hinge]

probably but i typped things like "how to interact beetwin blueprints" etc... So I saw all the alternativ with interfaces and function etc ...
But bypassing that every time I need to acces a variable is borring now xD

[zealous sundial]

Did someone already have an issue with Server RPC (execute on server) blueprint, fired two time without any reason ?

[spark steppe]

you could make an actor for that, and spawn it in the level, do your stuff in it's beginPlay event and then destroy itself

[zealous sundial]

#blueprint message
Update : Fixed, need to delete and re-do the blueprint, engine bug i guess.

[dreamy kindle]

[spark steppe]

check if your rig has 2 bones that are named head?!

usually that should've been caught earlier by whatever you use to make your rig, so it's just a guess

[pine trellis]

does anyone know now how I can stop my cubes from being places in a weird angle, it always use to place them flat

[mild lotus]

How do I set the enormous number of conditions for a large straight (either 1,2,3,4,5 OR 2,3,4,5,6)

since the dice don't have to be in order, they just have to all be there

In other words: "If all dice are different and 1 or 6, but not both"

then add 40 points

[spark steppe]

are you familar with bitmasks and bitwise operations?

[mild lotus]

(me?)

[spark steppe]

because that seems to be easy to solve with some bit operations

yea

[mild lotus]

I'm not

Fellow ben, you're my only hope

[spark steppe]

theres >10k other people online

[mild lotus]

literally you

my only hope

[spark steppe]

i don't know if you can even use bit stuff in blueprint

[fiery glen]

can you not convert an int to a bitset?

or whatever

[spark steppe]

yea you could work around that with ints

[mild lotus]

I have Dice 1 Result, Dice 2 Result, Dice 3 Result, Dice 4 Result, Dice 5 Result --- all stored as Int variables

[spark steppe]

maybe someone comes up with a better and easier idea to solve it

[fiery glen]

why not iterate over them all and add just set the bool to true if one is == 1?

[spark steppe]

yea, i would start with making an array out of the dices

so that you can literary iterate over them in a loop

[woeful pelican]

Haven't messed around with arrays or whatever in blueprints yet, but I think it should be possible to put all the values into an array thing and check it has the patterns you want that way

Like .includes

[spark steppe]

well theres a ton of possible patterns if your array isn't sorted by value

[mild lotus]

OR, hear me out: 1x2x3x4x5 = 120 and 2x3x4x5x6 = 720 so maybe I just say if the result of D1-5 = either 120 or 720 then you get 40 points

and assume there's no other combos

DONE

[spark steppe]

xD

[woeful pelican]

.includes or something like it would work fine unsorted. Course I don't think theres any reason to not sort it

[spark steppe]

1*2*2*1*5 nvm, shoot to early 😛

[woeful pelican]

But if pure math works go for it. Just verify theres no false positives

[mild lotus]

45116

4 5 1 1 6

[woeful pelican]

Easy solution seems to be to put all the values into an array, sort it, then compare it against the two straights

[mild lotus]

Yeah, im just so new to unreal I dont know how to do arrays yet

[woeful pelican]

Same lol. Might be called something different

[supple dome]

you just reinvented bitwise operations here, thats the exact logic you would do \😄

[spark steppe]

no

with bitwise you would flag every value, so a 1 on any dice would flip first bit, 4 on any dice the 4th

then you would do an bitwise and operation on both straights, if one is true you have a straight

if i didnt mess up my logic again, its 5am here... 😛

[supple dome]

im saying thats literally the same thing, 01 | 10 & 11, (1 + 2 = 3)

[spark steppe]

but idk how to solve that nice in BP

in c++ its like 2 lines of code if you squeeze the for loop into one line

[mild lotus]

ez ez

[spark steppe]

does that really work? i doubt it

[mild lotus]

i just tested it and it does

[spark steppe]

oh thats for the large straight

[mild lotus]

because all the dice have to be different

AND = 120 or 720

but yeah, small straight will be impossible lol

[supple dome]

ya i could swear you could bit shift, apparently theres not in bps

[woeful pelican]

I bet I could prove you wrong

[mild lotus]

prove it

and screenshot the code

plz

[tired wolf]

I'm trying to activate events in each player HUD with a Blueprint Interface Message in the gamemode, but every time I try to do it only the server receives the message. Does anyone know why? (I've tried making custom events that go to the server and then multicast it to each hud but it still won't work)

[dawn gazelle]

Game mode only exists on server.

[spark steppe]

the large straight should work in BP with the pseudo bitshifting, where you just do dice1 * 1, dice2 * 2, dice3 * 4, dice4 * 8, ... and then compare it against the two possible results

[tired wolf]

How can I call events to every player through it?

[dawn gazelle]

You can't. You have to use something else. You can use direct calls to each player controller, or through game state.

[tired wolf]

k

Thanks @dawn gazelle , all I needed to do was have all of the events controlled through the game state. I honestly had no idea what game states did but now I do thanks to you

[heavy burrow]

Hello Everyone
I had a quick question. Does anyone know why this happens? one side of my mesh has material and the other side is invisible?

[mild lotus]

thats just how some meshes are

like things that are exteriors and don't need interiors

[crimson saddle]

Is there a way to have an object that I can always reference easily? Kind of like how you can always get a reference to the level or the game instance. I want a base widget that will always be available, which is where I make notifications or whatever overlays.

[icy dragon]

Any reason not to use interfaces?

[heavy burrow]

right! How can I fix it because its a roof and I need the interior side on it. The mesh has its back faces in other software I dont know what here its invisible?

[icy dragon]

That is what known as "backface culling".

[crimson saddle]

How would I use an interface this way? I'm trying to avoid "Get all objects of..." if possible

[icy dragon]

Alternatively you can store the reference on game instance and clear it once you don't need it, if it's a global handler of some sort

[woeful pelican]

Here you go.

[mild lotus]

bruh, I'm not smart enough to understand

is this the small straight?

[woeful pelican]

Yep

[mild lotus]

1,2,3,4 or 2,3,4,5 or 3,4,5,6

give me a synopsis?

[woeful pelican]

This counts if there are 4 or more unique dice

That should work for your purposes

[mild lotus]

2,3,5,6 is unique though

and not a small straight

[woeful pelican]

Ah

Frick

Forgot about that

[mild lotus]

damn

[woeful pelican]

Right, lemme work on it some more then lol

[mild lotus]

ill be awake

lol

[crimson saddle]

I guess that might be the way to do it

[woeful pelican]

Just realised an easy check.

So, this is just checking for the raw minimum straights

Which are 1,2,3,4 , 2,3,4,5 and 3,4,5,6

This should also work, if you wanted less wires. Might even be more efficient but idk how blueprint compiles this

[mild lotus]

fucking brilliant

[shut hinge]

this might resolve the data table problem for dialog branching by putting the choice options into an array

[woeful pelican]

I think the thing I just did is an alternative to the bitwise stuff that was talked about earlier, though don't take my word

But theoretically I think you could do the same technique for the bigger straights too

[shut hinge]

yeah I'm trying to drive my dialog choice options using a data table as i have thousands of lines of dialog.

[woeful pelican]

Oh sorry I didn't see your message

choice options being in an array sounds like a more sensible way of doing things

Though I need to see what exactly you're working with

The blueprint above was just for finding straights in dice values

[shut hinge]

but i have to get dialog triggers (collision box) working with mouse, they seem to work once, but after that the booleans don't trigger the custom events. I also have the dialog triggers inside of each other with booleans to set them off when you click the mouse. So the only way I can get them to fire is to have to walk in the trigger and walk back out, triggers don't want to automatically activate when in them for some reason when pressing mouse. So when I click the mouse on the dialog option, it only fires it once instead of firing it always..

Dialog is all being run from data table, got that part working, but not dialog options branching fully working yet.

[woeful pelican]

I understood none of that. Screenshot?

[shut hinge]

ok hold on

here's what I tried to do with he triggers putting them inside of each other.

for each dialog branch but i don't think I can set it up that way.

Here's one of the dialog mouse button options

[woeful pelican]

Ideally you want one trigger per initiating npc I think. It'll get rid of the physical trigger confusion anyway.

And depending on a previously set variable (int works but there are better ways) within the initiating npc, it'll activate the appropriate conversation

That's one of the issues you mentioned right?

[shut hinge]

I find the booleans don't to trigger custom events more than once. I wasn't sure if this was to do with consume input or not. Or it was because of having the triggers inside of each other.

[woeful pelican]

What you probably want to check is the Level_Scripting level in the ContentExamples project

That gives proper demonstrations of triggers

The double doors in that level uses two custom events (one for opening, one for closing)

And one trigger

[shut hinge]

here's how I set up the dialog trigger (when you click on the NPC DIalog ption with the mouse).

[woeful pelican]

Sorry I'm focusing on one issue at a time here. Here's an example of a proper trigger activation. This is in the level blueprint

[shut hinge]

I used a custom event to fire it from the mouse. But found that this way of trying to fire off the code that brings up the dialog widget only works once instead of working always. And it only seems to fire once when inside of the trigger area, but to get it to fire off again, I have to leave the trigger area and walk back into it again which is not what I want the dialog options with the mouse to be doing.

I didn't use the level BP as my game has more than 1 map. So I stored the booleans in the game instance.

[winter burrow]

When doing a capsule trace by channel is there anyway to tell the start/end to be the size of a capsule collision mesh you have?

[woeful pelican]

I'm sorry I can't help more, but really this looks too overwhelming for me. Either that or I'm too tired to comprehend.

I'd suggest making a separate small empty test level and simplify your problem to the bare essentials. Make a trigger that prints a debug string and work from there to get the trigger behaviour you want

And again, ContentExamples project, level Level_scripting is a good example to learn from

[shut hinge]

i couldn't install in content examples, when I tried installing that project in the engine, the engine all crashed on me. The same as I couldn't install in the other demo projects, I didn't know why the engine crashed when trying to install it..

[icy dragon]

What's the error message you get?

[shut hinge]

i haven't got it installed in my current project but it is listed in the vault.

[woeful pelican]

You don't install it in the project. It creates a new project

[shut hinge]

Okay.

[woeful pelican]

So, what's the error you get when you press the 'Create Project' button?

[shut hinge]

installing itnow. I am using a PO3 machine. this machine does have an issue of losing HMD1 video signal at random.... Causing a black screen. Only way out of it if that happens it to reboot the machine.

[woeful pelican]

Sounds like a critical graphics card problem, which would explain the crashes

[icy dragon]

Do you have problems running UE4 games?

[shut hinge]

but how can that be, iI found out the predator machines have problems with losing the video signal at random.

[woeful pelican]

Do they? That's hilarious.

[shut hinge]

i think so because the machine won't keep its video signal all the time.

at the moment i can't do a final build of my game because i have some pack file errors that need resolving... but i can run the game in pie mode.

i'm currently using Engine Version 4.25 for my project.

I didn't put my game in Unreal Engine 5 as I only have 16 GB. of ram. Not 32 GB which I think is needed for that engine.. I'm running a GE Force 2080 Graphics Video Card.

[icy dragon]

UE5 can run in 8 GB of RAM btw

It's just that the whole Nanite thing that's quite costly.

[shut hinge]

okay so can people still upgrade from 4.25 up to unreal engine 5 ?

[icy dragon]

Yes, though at your own risk and only if you know what you're doing, given that it's still in early access and not production ready

[shut hinge]

I decided to stick to 4.25 just to be safe instead of version hopping

i haven't touched any packaging settings yet so they are on development.

[icy dragon]

TBH I'm still sticking with 4.26 until my project is complete
(Though I might hop into 4.28 if the master branch is to be believed)

[shut hinge]

how many gigabytes should the pie editor verision be for the project. (not the final packaged build).

andi've also got this other problem to resolve when stepping into dialog triggers. Overlapping widgets

[woeful pelican]

You might find better luck here: #instructions

[unkempt moth]

How do I use cast to reference two different characters? They are both child characters of third person bp. Do I just cast to the bp? I'm trying to get an enemy to kill my character(s) and they damage them down to 0 but they don't die and the enemy keeps attacking. I put the death function in the third person bp but I don't know how to get the separate characters to do their death animations after reaching 0 and to get the enemy to stop attacking after <= 0

[lusty elbow]

I have a struct for storing characters and their attributes (name, maxHealth, etc). But I also want to store their skills (e.g. Medical: 54, Marksmanship: 73). What data type should I use for that? A struct (Skill, SkillScore) within the struct? A dictionary/map?

[plucky harness]

How can i make it so that i spawn an actor always behind the owning character? Most likely need to do something with forward vector, but cant figure out what exactly

[fading wren]

really noob question but how to increase variable, till Branch - true branch is connectend to Input Axis (which works similiar as Event Tick)

[atomic salmon]

Spawn location = Forward Vector of the character * -1.0 * Distance from character + character world position

The * -1.0 inverts the forward vector so it becomes the “backward” vector

• distance is needed because those vectors are unit vectors

[plucky harness]

thanks, it worked

[fringe flame]

i am spawning bp projectile from character but it seems that is not affected by the scale

the scale i setup in the bp projectile

i want to make him smaller

how can i say except the character

[maiden wadi]

@unkempt mothYou're misunderstanding casting a little. Casting does not get you anything. Casting simply takes a reference you already have and tries to access different levels of the class hierarchy. If your reference is null or invalid, or cannot cast to that type then the cast will fail. But generally speaking, you don't need to cast for anything related to this. Usually you ApplyDamage on an actor being hit, that passes damage along, and you do damage calculations in the actor that got hit, lower their health and then check if they should be dead, if so put them in a dead state, remove their controller, ragdoll their mesh, disable collision, etc.

[high ocean]

Got a shitty problem: I have code iterating through an enum and getting a data table row based on the enum's name (enum to string to name ->get data table row). The problem is that we've added translations and now the whole code broke because the enum's name got changed and the dt entry cannot be found anymore... How would I get around it? 😐

[maiden wadi]

Why would translations affect that? You shouldn't be storing your enum as a string and using that. You should be storing the enum and using it where it's needed. If you're doing localization correctly, all of your data stays in whatever language you're coding in and only gets translated once it's changed to FText for display.

[runic plinth]

How would I go about separating an array into 2 arrays and pair them based on the index number?

[earnest tangle]

Loop the array and put items into the two separate arrays? Not really sure what the problem there is. You could also create a struct to contain the two items that need to be paired, and just keep them in one array inside the struct

[runic plinth]

How to filter which items go to which array? By a math operation with <= and >= ?

[stray wagon]

Hello do Strings or Event have size limits in packaged games that they dont have in editor?

I have a n event with a large string that work fine in editor but not in packaged game

I call this even with various strings, and consistently the one with large strings fail

[earnest tangle]

I don't know, this depends on what the data is you have in the array

and how you want to split them between the two

[runic plinth]

Will try to summarize, I have teleport actors in the level with a public actor ref variable that pairs these teleports. I have used the get all actors of class to put them into an array and now I want to split the array of these actors so then I can pair them based on the index.

[earnest tangle]

Ah, so let's say each teleport has a start and end "portal", and you want to have two arrays like StartPortals and EndPortals, where if you take some index from both, you get the matching portals?

[runic plinth]

Yeah thats the idea, or else going back through the teleport will land you elsewhere.

[earnest tangle]

Right... This might be easier if you create only one array with a struct which contains a reference to the start portal and end portal

You would need to compare the variable in the portal that tells you which other portal they match with when looping and then set up the appropriate values

[runic plinth]

Not sure if it changes anything in your suggestion but I also plan to have it randomize (shuffle) at BeginPlay

[earnest tangle]

Randomize the start/end pairings?

[runic plinth]

Randomize pairs,

[earnest tangle]

Ah, well that makes it easy to do this then

Get all the teleports, shuffle the list, then you just add them in order :)

[high ocean]

@maiden wadiThanks! I know I messed up when I made the code now. But is there a solution to it w/o rewriting - basically - 1/2 of the game?

[earnest tangle]

because you've randomized the list, if you iterate it in order, they will get random pairs assigned

[runic plinth]

Oh

[maiden wadi]

@high ocean What is in the Datatable?

That you're using the enum to access.

[high ocean]

@maiden wadiitems/resources.

then i get those entries to populate recipes

but since they're translated, the DT name is never found because I was retarded back when I made the code 🤦‍♂️

[maiden wadi]

Why aren't you using the Datatable's key for lookup?

[high ocean]

uhm... DT's "key"?

[maiden wadi]

The RowName.

[high ocean]

oh, it's a map in fact...rightj

[runic plinth]

Will try to make it work. Thank you for your suggestions.

[earnest tangle]

👍

[high ocean]

@maiden wadiIt's what I'm doing, but the enums are translated & I'm using their names:

So, i would somehow need to keep their names in english until they retrieve the info...

Tried changing language to en then back to it's set value (which I stored) but it won't work. I only get back english instead - maybe I can't change language at runtime 😐

[maiden wadi]

I'm a little confused, because enum names don't get translated. Not until you turn them in FText O.o

[earnest tangle]

this looks ilke an ftext conversion

if I remember the color of the pin correctly at least

if you lose that part of it, it should stop translating the names

[maiden wadi]

That's String and Name

[earnest tangle]

it's not, I just checked, the pink pins in the middle that connect the two are text pins

so yeah don't convert it to text and it might work correctly then

[maiden wadi]

You can't get Datatable Row from FText. The lighter pink line is an FName.

[earnest tangle]

Yes, but if you look at it it does a conversion to text in the middle of it

The value from the loop is first converted into text, then converted into name, this is I'm guessing where the translation occurs and breaks it

so it needs to either go directly into name, or go into string, or convert to culture invariant text instead of "regular" text

[maiden wadi]

I'm not following. There's no FText in his screenshot. It's Enum to String, to Name?

[maiden wadi]

That's a String, not Text.

[earnest tangle]

no it's not string, the pin in my screenshot on the right is string

look at the nodes that connect into the pins... the left pin goes into the literal text, the right pin goes into literal string. Text to String conversion :)

[maiden wadi]

You have the "Same" line arrow pointing at two different colors.

[earnest tangle]

it's a slightly different tone because of the compression I'm guessing, but it's definitely not the same color as the string pin

here's with less compression :P the pin color is definitely closer to the text pin (left) than the string pin (right)

I mean he could just go into the editor and hover over it and tell us what it says lol

so we can stop debating over the screenshots lol

[maiden wadi]

Unless he has written a templated blueprintable k2 node to let him get a Datatable row from a FText I can promise that's an FName.

[earnest tangle]

The one on the very right side of the conversion is a name, yes, going into the get DT row

but the pins in the middle are what I'm not sure about

[maiden wadi]

You can't convert an enum directly to FText.

[earnest tangle]

hm

well then I'm clearly mistaken and I cannot recognize colors

:D

(it wouldn't be the first time I don't match colors correctly)

Although I think you can go from enum to name so the conversion in the middle is still weird :)

I have no idea where the translation would be occurring though if not there 🤔

[maiden wadi]

@high ocean Are you using Unreal's Localization stuff or are you using a customized thing? Because there is one other way that might fail. Enums get different names in Packaged builds than in editor or standalone. That might mess up your find datatable row, but the enum to string should definitely not be translated.

[high ocean]

@maiden wadiYes, it's really bad practice, I'll try searching through the whole DT based on the enum itself with a search function. I'll come back with updates - thanks for ur help! 🙂

[autumn plover]

there a way to launch character with animation? Launch gets interrupted with animation...

[maiden wadi]

@high ocean What I did to get around that was just make some quick blueprint library functions for commonly used enums. Just input the enum value and switch on it, return a specific string for lookup.

[fathom shore]

I have a widget blueprint (GameWidget) which has a variable (eg: money) that is binded to a text and increases each time I click a button and I also have another widget blueprint (ShopWidget) that has a textblock that I want to bind to my variable so it can display the amount of money I have but in the shop blueprint so the player doesnt have to go to the GameWidget to see the amount of money he has and goes to the shop again, I tried casting to GameWidget but Im not sure what I should put in object

[fleet cedar]

Is triplanar the same as world aligned texture?

[worthy tendon]

where is money variable stored? in game widget?

[fathom shore]

yes the name money is just an example, The actual variable name is Total Clicks 0 but I called it money just for it to be easier to understand

[worthy tendon]

the better way would be to store money somewhere else, like player state, or player controller or some component of player. it's easier for shop widget to access to player then.

that is, both widgets would have access to player and it's variable

[fathom shore]

doesnt that mean ill have to rewrite everything that involves total clicks (The function to increase/save it)

[worthy tendon]

you even have your save logic in your widget? that's not really good. widgets should only bother with displaying information, not saving or doing anything else. @fathom shore

[fathom shore]

Thats the problem, My game is blank and its only a UMG game

And I don't know where I should put my saving function either

[spark steppe]

so guess you dont have a player actor at all?

[fathom shore]

I guess

[spark steppe]

well, then you might want to store all player related informations on the player controller (you make a custom one, which adds your variables)

[fathom shore]

what about player state

[spark steppe]

is it a multiplayer game?

[fathom shore]

no

[spark steppe]

playerstate seems to be mostly for data which has to be synced across multiple clients, so multiplayer games

[fathom shore]

should I select the playercontroller I made in the default modes

[spark steppe]

first you make your own blueprint class which extends playercontroller

[fathom shore]

Im not sure what you mean by extend

[spark steppe]

when you create a new blueprint you get a selection of classes which it can extend of, the lower half of the window has a list of all, search playercontroller there (and select it before you click create)

then in the unreal main menu theres a dropdown blueprints icon, there in the menus is some place to change the playercontroller class

[fathom shore]

this? @spark steppe

[spark steppe]

yes

[fathom shore]

alright i gtg for some time to set it up

[unkempt moth]

So do I apply the damage to each separate character? I have the enemy send a received damage that gets called by the

Third person character

[maiden wadi]

How are you applying damage currently?

[unkempt moth]

Give me one sec

[maiden wadi]

Do either of your prints run?

[unkempt moth]

Yup. Both of them do

It prints them out but after they are dead the enemy keeps attacking, but not making the health negative

I also tried putting a death animation on one of my characters that activates once they are down, but it isn't working

[maiden wadi]

You're not clearing the array then.

[unkempt moth]

Like this right?

[maiden wadi]

And the overlap is ending?

The rest of it looks fine. ApplyDamage, If not dead, lower health, check health, if below or at zero then die. Shouldn't be any issues there.

[unkempt moth]

The overlap does seem like it is ending. But I have two characters on a split screen and can't figure out how to play their death animations when dead.

[maiden wadi]

The Dead print is printing though?

[unkempt moth]

And to keep the enemy from continuing to attack nothing

Yup

It's working

[maiden wadi]

Hmm. Could be the death animation. As for the AI, you just have to determine what they can attack. In your case don't make them go after anything that is a third person character with IsDead == true.

[unkempt moth]

I have that here

Thanks for the help so far!

The Player ref is referencing a third person character

[maiden wadi]

And the reference is valid? You're not getting any Accessed None errors? That'll also return false by default if that pointer is invalid.

Well, presumably it's not invalid if the AI is going after it.

[unkempt moth]

Nope, no errors

[visual vigil]

how do i fire an event when widget is made visible

[desert briar]

Where can we assign level blueprint public variables?

Answer: You drag and drop actors from the world outliner window
https://docs.unrealengine.com/4.26/en-US/ProgrammingAndScripting/Blueprints/UserGuide/Types/LevelBlueprint/

[unkempt moth]

@maiden wadi

[fathom shore]

So do i basically create my total clicks variable in playercontroller instead of gamewidget and then cast to playercontroller to get the total clicks in gamewidget and shopwidget?

and then do everything I did in game widget but replacing the total clicks variable in it by the playerstate?

[jaunty solstice]

Any BP experts able to tell me how you would get a reference to a SubLevel BP?
Implementing an Interface on my Sublevel BP but in order to call I believe I need a reference to it.

[visual vigil]

Use event Dispatchers and subsribe to event on that level BP

Guys is it possible to just add a note in BP, I am not talking about comment Just a small note on top of node

[unkempt moth]

I saw that somewhere, there are three dots above the node but I'm not sure how to access it

Ah, hover over the node then the three dots appear, double click them

@visual vigil

[visual vigil]

thanks

[unkempt moth]

Np, I'm just glad I could actually answer someone else's question for a change! 😄

[fathom shore]

help?

[jaunty solstice]

Answering my own question in case it helps anyone. From any Actor BP on the current level use 'GetStreamingLevel' which only works with Sublevels and for Package Name use the name of your Sublevel. Then just send a interface message from the Return Value!

[signal cosmos]

Hi guys, I try to get the value of my controller rotation from my Pawn BP, but it resturns 0, whatever the way I try, I can't get my control rotation. Why is that?

[fathom shore]

Where the problem occurs

[fathom shore]

if i create the widget then close the game it displays this

[signal cosmos]

I found the solution to my problem. In the controller class defaults you have to uncheck "Set control rotation from pawn movement" in order to get the correct rotation of the controller from the Pawn.

[fathom shore]

the value disappears if i do that @burnt nest

beside that mouse cursor should be a number

[burnt nest]

Then your cast is failing, probably because you're not actually using Myplayercontroller as the PlayerController.

[fathom shore]

yeah how do I use it as the PlayerController?

[burnt nest]

You do that in the game mode, or here.

[fathom shore]

its grayed out for me

[burnt nest]

Then create your own GameMode and change that.

[fathom shore]

Like this?

yeah it works now

[fathom shore]

ok I binded the playercontroller's total clicks to the text and increasing it too but where should I put my saving function
