blueprint

[orchid garden]

my inventory & hud have widgets nested in widgets.

[ocean imp]

Anyone able to point me in the right direction of making a multiplayer game? I need to get name inputs of players and get all players to be able to join in on a listening server.

[coarse forge]

so I find myself wanted to put a box behind some buttons.. but now its like.. maybe just make the buttons a widget.. and then include that widget in another widget.. since some of the things like border only accepts one child

nm.. version 2 lol.. not needed

[wooden holly]

No I don't think it worked

I have it exactly like you

[orchid garden]

this should render without your player (owning character being the player reference):

(scene capture image is the capture camera) @wooden holly

[wooden holly]

And what do I use here?

[orchid garden]

the actor you don't want it to render

[wooden holly]

and do you know where I get the character?

[orchid garden]

get a reference to your player character and attach it there

[wooden holly]

okay

thx

[orchid garden]

use a Self Refrence

sense that camera is on your player

[wooden holly]

Like this?

[orchid garden]

yep

[wooden holly]

and what do I need to do next?

[orchid garden]

?

[wooden holly]

it doesn't work yet 😦

[orchid garden]

needs to be connected to something like your begin play

[wooden holly]

okay

How can I get multiple events of BeginPlay?

[orchid garden]

you don't

[wooden holly]

But I also need to connect it to my HUD Widget

[orchid garden]

just connect it up after that.

[wooden holly]

So I have it now like this, but it still doesn't work 😦

[orchid garden]

yep

[wooden holly]

Do you know why?

[orchid garden]

did you change the render mode of the camera like i showed?

[wooden holly]

oh no

sorry I forgot

okay looks better, but now the minimap doesn't work anymore

the arrow is just an image

[orchid garden]

hrm odd... i didn't have to add things to the show only on mine :/

anyone know why??

[wooden holly]

I mean there is a little shadow:

It's moving when I turn the camera

[orchid garden]

yeah but it seems to be hiding everything not just the player :/

[unique falcon]

good evening you lovely lot, bit of a weird question time - are there any neat shorthand ways/blueprint nodes i can use to do something but only if a value has changed since last time i hit that node?

[wooden holly]

okay thanks @orchid garden for the help. I think I'll leave it today as it is 🙂

[orchid garden]

@wooden holly try this istead, seems to work the same as that should of:

don't forget to set render mode

[shy path]

I’ve made a custom blueprint triggerbox, now is there any way to turn all the old triggerboxes I placed into the new bp version, so I don’t have to replace them?

Or copy the coordinates from the old to the new, I edited them with brush tool so they have custom shapes

[maiden wadi]

@coarse forge I do that often with my widgets. For example, if you want a button with a simple border with the same normal button functionality.

[mental tendon]

hey guys do you mind taking a look at my question ?#ue4-general message

[maiden wadi]

@coarse forge Then you can just reuse the button where ever with a few changes to the exposed values that you want, like different materials, or colors.

@shy path You mean in your level? Replacing them with the new one in editor?

[wooden mural]

Think of Begin Play as a function. In code you can't define a function twice

[shy path]

@maiden wadi yes

[maiden wadi]

@shy path Try selecting one of the old ones, and using the Replace Selected Actors With.

[shy path]

That works, but changes the scale

And the thing is I spent some time making the volumes perfect with the brush tool, but I can’t move the vertices around now that it’s a triggerbox.

[robust jacinth]

When I spawn a spear in my game I use GetActorRotation as an input to Make Transform, which is plugged into SpawnActor.
But now I want to rotate the spear a bit, like 30 or 40 degrees upwards, but I don't know what to plug in between GetActorRotation and MakeTransform.

Any tips on what I could use? 🙂

Not a math wiz, so I am not sure what to do...

Converting the rotation to a vector, add 0,40,0 to it, and then turning it back to a rotation?

Can't seem to find a node that would let me add 40 degrees to the rotation. :/

[sick creek]

@robust jacinth

also

[robust jacinth]

Tried this, did not work. No rotation added.
Will try your other suggestion now.

Works like a charm, and now I learned that you can split the imputs! :)
Thanks a bunch, @sick creek !

[sick creek]

np 🙂

[white lynx]

How do you solve "Failed import for bool property referenced by export Function" for blueprints? I get that every time I load the engine but the property it complains on compiles fine and runs fine in game

[digital nova]

hello, is there a way to get how many cells of a destructible mesh are still not destroyed ?

[solemn parcel]

These two nodes count from -1 to 1 right ? Does it count 0.00 ?

[digital nova]

yes @solemn parcel

it should

[dense abyss]

you know that's going to return true for every number, right?

[solemn parcel]

So less or equal in that example count from 1 to -infinite ?

[digital nova]

nope

[solemn parcel]

Adding a 'And' Boolean would make more sense to clamp between 1 and -1 ?

[dense abyss]

if you replace the OR with AND then it'd only be true for numbers -1 to 1

[digital nova]

yep

[dense abyss]

with OR all numbers return true

[solemn parcel]

I just realised thati'm so tired my code doesn't make sense anymore

so that is what i'm saying, a '+1' as equal or less float will take into account +1, 0, -1, all numbers in between and all number after -1 ?

[dense abyss]

<= 1 means 1 and everything below

[solemn parcel]

Thanks a lot

[drifting vortex]

Is there any way to access navmesh data via blueprints? I'm poking influence maps and I think it would be best if I used the navmesh as a basis for the map itself, kinda like Killzone did

[sick creek]

@drifting vortex

[orchid garden]

i think everyones been there at one point or another lol

[alpine terrace]

Guys can sb. help me?
I have an attack anim montage (a long combo animation) with root motion enabled and I would like to use notifies to rotate my player between every single attack of the long combo. I would really appreciate it also it would be nice if this could be done in BP
Basically I want the player to be able to correct the direction of his or her attack in case the target is moving/running around

[trim matrix]

Does anyone have any clue on why this is not working?

This is supposed to move character when joystick on VR controller is activated, but it does nothing

[dense tulip]

Someone know why this node show in red ?

[dawn gazelle]

The reference no longer exists. Just right-click on it and select refresh

[dense tulip]

Thanks

[calm cargo]

did not know you could do that lol

[versed stirrup]

Is there a way to launch all enemy AI that have a tag?

[rough jay]

that target can u just put foreachloop and the blue nodes connect?

[rough jay]

fuck, yeah

[versed stirrup]

is there a launch node that takes actor as input?

ive figured it out, thanks for that for each loop 😄

[dense tulip]

Wondering is someone could help me figure out this issue, how can i fix the bottom part

[dawn gazelle]

That cast node you have there requires you to attach execution paths to either end. You should probably place it before the Set Percent node.

Plus, I'm not sure if your player reference variable is going to be of the same class hierarchy as WB_HUD.

[barren frigate]

how to remove an array item if it's not being hit anymore by a multitrace (multiSphereTraceByChannel)? the trace channel 'pawnV2' has the response set to 'overlap' so I can get multiple hits at once

[stiff chasm]

im trying to make a pawn know if its player 2

[rough jay]

im pretty sure thats just getting all actors with the specific class and tag so it invalidates trying to go by tagand getting the actors purely off the tag im pretty sure

[stiff chasm]

but i cant seem to get theplayer controller id of the player that is possesing my pawn

how do i do that

Charecter BP now pawn

best i can do is this

[dawn gazelle]

Probably want to clear your "Aim Tag Array" variable before your loop?

[rough jay]

removeitem

[barren frigate]

I know this, but I can't seem to find a way to see if the said actor is still hit by the multi trace

[barren frigate]

dude, that was on point!

thanks a lot!

[stiff chasm]

Thank you

[fleet crest]

Just asking to understand it, cause it confused me in a video.
Isn't Blocking Hit the same as the Return Value from LineTraceByChannel?

[stiff chasm]

How are you lines straightn't?

or like

curved and straight

[stiff chasm]

Paid im guessing

thanks

[fleet crest]

Yeah it had a discount i believe and thought it was nice so i grabbed it xD

[trim matrix]

can anyone help a noob out real quick? holding shift speeds up my character but my sprint animation isn't working 😦

[velvet wigeon]

imma add that to my wishlist

[proud hull]

Did you update your blend space to include the sprint animation?

[trim matrix]

yep

[proud hull]

Also the min/max values in the blend space?

[trim matrix]

also I didn't update

[proud hull]

max really

[trim matrix]

I made a new blendspace

sprint_bs

[proud hull]

New blend space is ok too, can you show a screenshot of it?

[trim matrix]

and yes I did use the values

screenshot of which part?

[dawn gazelle]

No. A return value on a trace means that it has some data for you in your Out Hit and I believe Blocking hit refers specifically to "blocked" hit results which are different from overlaps.

[proud hull]

The whole blend space if you can. Include the details to see the values. Also a screenshot of your animation blueprint.

[trim matrix]

okay

[somber bear]

anyone ever run into a bug where values arent being saved on a child bp?

if yes what was the work around hah

[trim matrix]

only the top part is the run animation

maybe thats the issue but I doubt it because I've messed around with it a bit

[fleet crest]

Thanks, guess will look more into it. I still don't understand the difference cause return values says it's true when it hit something but i don't know what a 'blocking' hit is rn.

[dawn gazelle]

Example: You could have a sniper rifle ability where you want to shoot through a wall but also leave a mark on that wall when it is hit. That would mean you should be using a blocked trace channel for the character, but has an overlap for static meshes. So then you can get 2 results from your trace, one that blocks and one that does not, the overlap hit would be the wall, the character would be the hit.

[stiff chasm]

Both my players have an id of 0

Can 2 Players have the same id

im confused

[dawn gazelle]

This an online multiplayer game you're trying to set up or local multiplayer?

[stiff chasm]

Both

i want it to be both

but im working on local right now

[fleet crest]

Ahh now i understood it thanks 🙂

[proud hull]

What are each of the animations there, from top to bottom? Run, walk, idle, walk backwards, but there are 5 of them I see and you have 4 animations?

[trim matrix]

the other four are all walk animations, the top is run

[dawn gazelle]

Player controllers do not replicate and do not know about other player controllers, so they always return 0. Your game mode is the only place that would be able to determine which particular controller ID # any specific controller is.

[proud hull]

You should include all the animations in the same blend space. Also you might want to use a 1D blend space instead of 2D, unless you will be including strafing later on.

[trim matrix]

I'll prob include crouching and strafing later

fuck wait-

maybe I should've included the idle at the bottom

[proud hull]

crouching will be its own separate blend space later

[trim matrix]

nevermind

the speed is 300

[proud hull]

But all regular movements can be in the same one.

[trim matrix]

at the bottom

[trim matrix]

oh okay

[proud hull]

Set speed to start at a lower number, you can even do negative numbers to include your walk backward animation.

[trim matrix]

currently I don't have walk backwards and everything, for the game I'm making I'm starting basic

[proud hull]

Okay, so go with 0 to whatever you sprint speed is.

[trim matrix]

okay I'll try it

NOPE

[proud hull]

Then the bottom will be idle, walk set to your maximum walking animation speed, sprint set to your maximum sprint speed.

[trim matrix]

whoops caps

[proud hull]

We then have to move into your animation blueprint to check and see how speed is set there.

[trim matrix]

oh okay

yeah doesn't work : (

it's fine, thanks for the help!

[proud hull]

Still need to setup the animation blueprint, haha.

[trim matrix]

I'll try again after I have dinner

[tardy kayak]

how do I create a static mesh component at runtime with blueprints?

[lusty grotto]

Hey, I'm kinda new to blueprinting and I am working on a VR shooting game. I have made the gun shoot when pressing the trigger, however it doesn't matter if the gun is in the hand or not, the gun will shoot regardless.

I made a boolean, and branch

But when I call the condition for the branch, it says this blueprint (self) is not a blueprint

Idk if this even makes sense

[dawn gazelle]

how about a screenshot of what you've done? I've never seen that sort of error before.

[lusty grotto]

Ah ok, one moment

So the first one is my trigger function

[dawn gazelle]

So in that first screenshot, you're trying to get a reference to a boolean in a different blueprint. You need a reference to the object that has that boolean going into that node that has the error.

[lusty grotto]

Bool29 is a component I made

I tried using Get all actors

class

[dawn gazelle]

The first screenshot is in your character, yes?

[lusty grotto]

Its in the motion controller Pawn

Im using VR default package

[dawn gazelle]

ok, that's fine. the component that you created - is that already added on your pawn?

[lusty grotto]

I created it in my Gun blueprint, where the trigger action is.

Oh I tried adding it, but thats where im getting the error.

When I create the branch, im trying to add the condition bool29, because I set it in the Motion controller Pawn

[quiet token]

Hey everyone! I have a problem here and would appreciate some ideas, cuz i'm kinda noobish ^^ I'm in first person and want my ducking to go smoothly and not so abrupt. This is my solution so far, so i can use the camera lag on the spring arm, ,but i'm not so pleased with the outcome yet.

In my game you jump alot so its important that the camera flows when u jump onto somthin higher for example

not up and down all the time

but i have no clue bout interps and stuff

[dawn gazelle]

Ok, so you have a component (which is where you're trying to do this test) that is attached to a Gun actor. And you want the boolean value from your pawn, yes?

[lusty grotto]

Yes

[dawn gazelle]

You could do it using this... But you need the specific class of the component. Then from there, you should be able to drag the return pin to the node with the error.

[lusty grotto]

This is kinda what I meant. The bool component call "bool29" is created in the gun blueprint, as you can see I set the bool value. Now Im trying to get the bool29 value in the second screenshot, however i do not know how to set up the connection between these two blueprint

That seems like it would help

I meant second screenshot^

[quiet token]

mh

[quick lance]

I have a get game mode node behind an authority switch, and it's still giving me null. Any ideas why that might be happening?

[dawn gazelle]

What BP are you calling get game mode from?

[quick lance]

A custom BP actor I made that is placed in world and doesn't make the call until I walk over a collider. What is most strange is that my cast to my custom game mode doesn't fail, but the Game Mode Base function Get Num Players is returning 0.

[quiet token]

No ideas how i could get smooth crouch in first person?

[quick lance]

Okay...they're giving me null while im looking at them via breakpoints at runtime, but they're valid if i let the prints run. Welp, nevermind. guess it's an engine bug.

[junior thunder]

If you have a collider, and it overlaps several other colliders on the same frame( or tick) does its "On Component begin overlap" trigger once per collider overlapped or just once period

[odd ember]

should trigger per collider but knowing the collision system it's probably not going to be happy

[junior thunder]

so if I have an on component begin overlap function for the black circle here overlapping 3 things on the same frame(an explosion for example), it will call the black circle's "On component begin overlap" event 3 times - once per red square?

[dawn gazelle]

You were close with what you have.

Make sure your timeline is set to however long you want the crouch motion to be, and set the value as 0 at the start, and 1 at the end.

[quiet token]

ahhhh, thank u alot, i'll try it out and tell u in a min

[dawn gazelle]

Adjust the lerp value for how low you want to go as well.

[quiet token]

camera or spring arm?

cuz my cam is attached to the arm i'd use that right?

[dawn gazelle]

I just did camera on mine as it was easily accessible

[quiet token]

kk

[dawn gazelle]

You may also want to do something like this on Begin Play and fix the Lerp's 0 value to it.

[quiet token]

thanks alot!! i try to play with the settings and tell u in a few mins if its workin ❤️

Yooooo, it works perfect. thanks alot!

Ure a legend

[dawn gazelle]

Yes, 3 times, one per square.

[maiden wadi]

@quick lance Make sure you breakpoint past where you want to see the value. It doesn't show it if you breakpoint on the exact node that's getting it, because it'll break when that node is executed, and before it retrieves values from other functions.

[tranquil cloak]

if i create a bool that is set in the same blueprint and is public as you can see

could i call the "get bool" into another blueprint and if so what would the target be

this is basically same problem

as the one above

well exact

[dawn gazelle]

The target has to be the object that the bool is stored on.

[tranquil cloak]

its on another blueprint

[dawn gazelle]

Then you need to get a reference to that blueprint.

[tranquil cloak]

ive been trying to do that, dont know exactly how

does it need to be a sub class?

[dawn gazelle]

No. You need to set variables to the references of the things you're trying to use. For example, you have your interface call here... That "attach to" pin is going to be a reference to something. Perhaps you could feed back a reference to "self" back to that "attach to" object.

[tranquil cloak]

but how is that done

how do i feedback the reference

[dawn gazelle]

You need to create a variable on the thing that needs to store the reference. From that "attach to" pin, you may need to cast to the object type, then do a set to the newly created variable with a reference to self.

As an example...

I've created a reference variable called "interacted" that stores an "item" object reference.

This variables was created on my object "BP_PlayerController"

On my item, I'm using an interface, similar to you. and from it, I can get a reference to my player controller and set the interacted value to self.

That means I can reference that instance of item on my "BP_PlayerController" object by using the "Interacted" variable.

[peak umbra]

If anyone can help, I have a question.
I'm trying to implement level streaming for a level by level progression game. Is this a good option or is there a better one around?

So 1-1, 1-2, type of progression

[junior thunder]

Upon further testing in a toy example
it does generate 3 begin overlap events
but
I added a node to stop generating overlap events to see what happens, and even if it overlaps 3 things that all overlap on the same tick
when you set it to stop generating overlap events it will prevent it from seeing other overlap events that have yet to happen on that tick
I'm checking this because I want to disable my collider after it hits something, but also hit everything it overlaps.

So my current thought is to get all relevant overlapping actors on the first overlap event, do whatever collision logic to each of them, then disable overlap events so it doesn't call it for each overlapping actor

[dawn gazelle]

Would a sphere trace perhaps be better to use? Then you just get all the hit results that are nearby?

[edgy halo]

Hey how can I snap to the closest multiple of a number N using blueprints?

I am making a bomberman clone so I can play with my friends but I need to spawn the bomb on those specific areas

[edgy halo]

In my case the number is 50

I don't need help with the logic, more help with the blueprints part

[junior thunder]

In some cases maybe, but the specific example I'm looking at is a fast moving linear dash punch of a character with a big fist
my current plan is to have a collider sitting on the actor disabled until the punch happens
then activate it during the punch, looking just for overlaps with a specific class(enemies)
if it overlaps something part of the logic includes disabling it again because the punch is done.
If I were to use sphere traces I'd have to do it every frame, is that more efficient than having a collider doing the checking?

[tranquil cloak]

the variable type is of the type that the blueprint_gun class is

would this be able to access the bool29 variable in the other blueprint

[maiden wadi]

@tranquil cloak I strongly recommend following this if you're new to how to handle references to objects. https://www.youtube.com/watch?v=EM_HYqQdToE

[tranquil cloak]

i will check it out, thank you

[maiden wadi]

@tranquil cloak In short to try to answer your question besides a two hour long video. Your variable is empty unless you've populated it. You've told it what "Type" of object it should use, but not which one specifically that it should point to. But I still recommend the video.

[hollow dust]

If you’re trying to access a different blueprint I think you have to use “Cast To (blueprint)”

But I could be wrong, I am new

[vocal urchin]

Because I'm terrible at vector maths, I'm having a hard time aligning a grid of points I've created to the axis of my ship. I thought this would be easy and they'd come in aligned because I used Relative Location, but clearly not. How do I compute them to stay in line with the x axis of the ship?

[maiden wadi]

@hollow dust Casting does not get you a reference. Casting simply attempts to change the reference type.

[proven moss]

is there anything i can use instead of event beginplay or a way to add a delay before it? i need to trigger something 2 seconds after the game starts

[quiet token]

@maiden wadi Hey! Maybe u have a little moment to help me out again?

[maiden wadi]

@quiet token What are you having trouble with?

[proven moss]

i need the event beginplay to trigger two seconds after the game starts will it work im trying to fix a bug in the game

[maiden wadi]

@vocal urchin It looks like your Grid Points are already in world space. How are you getting them in the first place? It may be easier to create them in local space based on the ship and then transform them to world space.

[vocal urchin]

I'm using the "Create Grid Mesh Welded", and then pulling points from that.

Figured it would be easier. Also, how does one create coordinates in local space?

[quiet token]

I want my player to keep only his forward momentum when he jumps, so the player can let go of the "W" key and still flies forward. And when then player is in air and pushes "A" or "D" for Strafing left or right, the input should be as if he'd push "W" and "A" together for example. I need this to make the player strafe a curve to the left for example.

@maiden wadi ^^

[proven moss]

i added a slow motion feature to the game but if im using the slow motion and at the same time restarting the level the global time will stay the same as the slowmotion but it will start only about two seconds after the game starts i added this to try fix it but the problem is that the global time is 1 when i start but turn to 0.2 two seconds after the level restart

[quiet token]

With this W and A together i mean, that in air while inputtin only left, the input should be forward + left

[proven moss]

if im doing it on event tick and adding a print string is does print but on the begin play it wont

[maiden wadi]

@quiet token Is this for a character class?

[quiet token]

mycharactercontroller(self)

so the player bp

wich i'm controllin

mom i screen it for u

u saw it yesterday

[maiden wadi]

The CharacterMovementComponent has some settings for better control while falling.

[quiet token]

yeah i tweaked that

the thing i want to archive is that the player can let go of "forward" after he jumped, still maintaining his momentum in the direction he had at the moment he jumped. When pressin "left" in air then, he would just move the player a little to the left, but it want him to make a curve, like a bow to the left

this is what i have when i'm pressin manually "forward + left" in air right now, but i want it to feel more like a strafejump in counterstrike

@maiden wadi at the right of the 2nd pic there is the jump action

[edgy halo]

Thank you @dawn gazelle

@dawn gazelle also im spawning a bomb with a collider...I want the collider to be off till the character moves from the position and then turn on

How can I do so?

[fossil gust]

How can I set a blueprint to do substract or add based on the event that fires it?

In this case, I want lower door to substract, and raise door to add. Is there a way to do that without duplicating more boxes?

[blissful lava]

Put that logic into a function; boolean for input that controls a branch that determines what the function will output

[viscid shard]

I kinda figured out a working method but how can i change the 0 - 360 camera rotation to a proper set controller yaw. if i divide the mouse axis by 2.5 i get it pretty close but if you rotate the mouse around and around eventually itll be off. and this method is random so i dont like it. but im so new to UE4 and dont know how the controller works because theres rotations then YAW and axis.

[bitter lance]

Is there anyone who have used functiont Editor Apply Splines ?
link: ||https://docs.unrealengine.com/en-US/BlueprintAPI/Landscape/Editor/EditorApplySpline/index.html||

[twilit heath]

@vocal urchin don't know if you have a handy blueprint function for creating the grid in local space, but it shouldn't be too hard to do manually

you can also mark the Vector array in details panel as MakeEditWidget, it would create a small widget for every vector in it you can drag around, if you need to fine tune placement manually

once you have the local space array, you just call use TransformLocation node giving it a vector from the array and ship actors transform

and that will translate the coordinate from local into world space

(accounting for both rotation and scale)

[viscid shard]

is there no way to see the controller and its variable ? i dont understand how itsZ Axis / Yaw works because nothing adds up.

[odd ember]

yaw rotates around the Z/up axis

a good rule of thumb is pitch is a nodding movement, yaw is a shaking head movement, roll is moving the head between the shoulders

[cold sinew]

Hi guys i have a static mesh i want to replace it with new static mesh according to player settings and i want to check if that mesh is changed

What best optimized method i can use ??

Like i have broken electrical cable i want to change it with new one

[odd veldt]

Does the node "is loaded" not work on instanced streamed levels? It gets to early "true", also "is loading assets" has the same problem

[orchid garden]

Thought about doing something similar in mine for wires and water lines., what i was thinking was turn it into a actor, stick a static mesh component in it for the broken wire, use that as your wire, then when the player fixes the wire just swap the static mesh inside the actor to the fixed mesh. You could even put your emitters for the broken wire sparks inside the actor and disable them when the wire is repaired.

[cold sinew]

So Static Component ?...
im using a Function fires with Construction Script Spawning the Broken Cable Static Mesh and changing that using another function destroying the old cable and spawning new one

[solemn parcel]

So I've downloaded a new skeletal mesh character from the marketplace. I've created a BP for him. Added his Skeletal Mesh in the BP, copied a version of ThirdPersonCharacterAnimBP that I renamed, and used it as the Anim Class in the new Character BP. Yet the character isn't animated, why ?

[cold sinew]

but i want to be very short and useful method other than mine

[orchid garden]

you don't have to destroy the cable, just replace the mesh inside the actor

[cold sinew]

Oh

i will try what i can do xD

[zealous moth]

@solemn parcel is the mesh retargeted to the UE4 skeleton? that's typically why it isn't animated. When you say you copied a version of the animBP, did you just copy paste it or retarget it?

[orchid garden]

like this YAO - you take the component drag a pin off, and type 'set static mesh' then for the mesh that will be replacing it you attach a reference to that mesh to new mesh.

the nice thing about doing it in a actor is you can put all the functions for handling the cable getting fixed / broken inside of it.

my player dropped items work that way too, so i have 1 master that handles all player dropped items:

[dusty ibex]

Hello. Can someone point me to some save load tutorials that handle level state. For example, when I load game I want all items that I picked to not show on the level.

[cold sinew]

Yes also i was using the Cable Component but its hard to replicate Thats why i switched to Static Mesh Cable Then i will set Broken Cables as a quest the player will fix the cables and count this completed mission

[cold sinew]

and thanks i will check and i hope we are not working on Same Project idea

[orchid garden]

haha doubtful 😉

[cold sinew]

❤️

[solemn parcel]

@zealous moth Thanks, I just copy paste before, now I retargeted and it works 😉

[orchid garden]

im really only working on my inventory system and player interaction system, after that I can decide what type of game I want to make heh 🙂 its a multipurpose inventory so could be used for just about anything.

[cold sinew]

Nice goodluck

Also another question please if you are working on Interaction system xD

Im trying to set a widget interaction with movement and draw a wire between UI and object

Like watchdogs widget

[odd ember]

can you post a reference screenshot

[orchid garden]

ah watchdogs, yeah im not doing anything like that, least not yet

(fun game though heh)

[cold sinew]

I dont have ss i saw it somewhere like small window popup with wire conected to the object

[zealous moth]

@cold sinew typically the "widget" would be attached to an actor. You can definitely do this wire system using a spline but this will take a bit of math on your part on how to calculate it and how it works

[cold sinew]

Calculate the Widget screen position and the actor world location and the distance between them

Right ?

[zealous moth]

calculate whatever you want it to do

[cold sinew]

Hmmm also i will try it

[odd ember]

you can project screen position to world and vice versa, but I can't imagine it having the effect that you're going for

but then again I can't really picture what you want currently

so hard to say

[cold sinew]

I will draw it wait xP

[zealous moth]

it's like a health bar but also it is connected to the main player character through a wire.

[odd ember]

I get the concept I just don't see how it relates to a screen space widget

[orchid garden]

like this CranzEstebogen:
https://s3.amazonaws.com/assets.primagames.com/_resized/gn/images/guides/content/1_toppage_Training.jpg_1600x800_.jpg

[zealous moth]

@dusty ibex https://www.youtube.com/channel/UCa-FWkvOAnSLdxaA6f5BtMg

[orchid garden]

see how it has the interconnecting lines between the objects?

[zealous moth]

@dusty ibex check under the "basic game tutorial"

[cold sinew]

True

[zealous moth]

@dusty ibex it details how to do it and includes a demo for FPS games on persistent data

ah i see, so not to the player, i thought you meant that gamplay feature where he hacks, not the tooltip ui

[cold sinew]

Like the object when the player reachs close it will popup

[zealous moth]

you would just need to add an arm element with variable length.

[cold sinew]

Yes

[zealous moth]

for the popup, add to your character either a collision box or a raytrace. Collision box is probably way better. When intercepting, make it pop up

[cold sinew]

I was thinking to make it 3D widget and make it as a child actor inside each object i want to interact with

Or inside the main parent

And inherit it

[odd ember]

@cold sinew is that screen space or is it world space? world space that's fairly simple, screen space to world space will be a challenge

[orchid garden]

in watchdogs its worldbased

[cold sinew]

Its world space i think because its spawns and resize according to player location and distance

[odd ember]

should be fairly simple then, place it as a component on the interaction object

draw a line to it

done

all the info is right there in the actor

if you want it to also draw a line to the player you will have that information if the player overlaps the interaction in the first place

[orchid garden]

its a little more complex then that in watchdogs

[cold sinew]

Yes i wont it that complex just between interacted object and player small window

I wont all that wires and pointers

[orchid garden]

some items are item to item, so that concept would work @odd ember others are specific items in range, some just singular objects to players phone, some actors in x range.

[odd ember]

there's a few ways you could make it work with other specific items in range

[orchid garden]

its pretty intresting how they did the whole cellphone hacking bit really 🙂

[ancient topaz]

Hello !!! Can you help me guys? I have a camera that goes through textures, how can I get textures to block it? I set textures to block the camera, but it still goes through textures. It also goes through the Camera blocking Volume

[cold sinew]

big teams xD

[odd ember]

probably simplest would be to check overlapping actors of type when the player overlaps and use a loop to trace lines to them

it's not that hard

[solemn parcel]

Why while my line trace hits that wall it hits LeftArm_StaticMesh ?

[odd ember]

a simpler solution with more setup would be to set up an array that is editable where you can add actor entries that are then traced to when the player overlaps

[cold sinew]

I will try and record the result

[orchid garden]

on your camera boom:

[ancient topaz]

yes, i do that.

[cold sinew]

From where is the line trace starts ??

[ancient topaz]

@orchid garden

[solemn parcel]

@cold sinew

A custom static mesh named ShootingPoint. The thing is the line trace detects this only against that wall for some reason

[cold sinew]

Are you sure the name of the wall is not Left Arm staticmesh ??

If its just with that wall

[solemn parcel]

ahah

it is totally.

[sick creek]

lol

[solemn parcel]

I feel dumb

[ancient topaz]

@orchid garden And texture have a camera block collision

[solemn parcel]

😄 but thanks

[cold sinew]

Lol its happens no worry

[odd ember]

have you tried google?

[orchid garden]

does the wall have collision?

[cold sinew]

I think he is using render target

[odd ember]

because this sounds like something a google search could answer

[ancient topaz]

@orchid garden

yes

[cold sinew]

Is that happening with all walls or just specific one

[cold sinew]

Try to scroll down from this window and set the collision channel and type blocking the camera

[ancient topaz]

@cold sinew

[orchid garden]

hrm... idk wwyn, it should be blocking the camera with those settings and sense the mesh has collision...

[worn nebula]

Hey guys, wondering if I just get a little prompt in the right direction. I want to make a death scene for the player if they get caught. How can I do it so the sequence will player at the exact location of the character, and then face in the direction of where the enemy was? if that makes sense. Everything I've tried it looks the rotation if I want to do it in a sequence

[ancient topaz]

all blocking, without camera(((

[orchid garden]

i litterally have the same camera settings, my mesh is set to 'blockall' for collision, static mesh in scene, and if my camera gets too close:

yours should be doing the same

[flint gyro]

Searched for it but I did not find anything that resembles it

[odd ember]

does the mesh have complex collision? if not, what are the project collision settings?

[orchid garden]

looks like its simple collsion on the mesh CranzEstebogen from his screenshot.

[odd ember]

hence why I'm asking

[ancient topaz]

@odd ember

[odd ember]

try to set it to use simple as complex for the mesh

instead of project default

[orchid garden]

complex or simple it should still block the camera.

with project default

[odd ember]

not if the project default has been edited for instance

and hunting down bugs you can never assert these things

hence why it's necessary to double check

[plain flare]

Hey, I want to create an object in game. But if it is already exists, I dont want to create. How can I check that ?

Actually not object, it is widget blueprint

But it is not important part, I want to say "If it isn't exist, create that."

[orchid garden]

i honestly don't get where your coming from on this one cause if the project settings are set to use only complex then his character would be able to walk through the wall as well not just a camera issue.

[odd ember]

again not if both the project default and the specific wall has been edited

[orchid garden]

still don't get where your coming from.

[ancient topaz]

@odd ember I try to change arm and camera

[odd ember]

just because you don't understand it doesn't mean it's wrong @orchid garden

[orchid garden]

just because you say "it works that way" doesn't mean its right @odd ember

[odd ember]

I'm not saying "it works that way"

[orchid garden]

...

[odd ember]

I'm saying there is a case that hasn't been checked, or double checked. you're making assumptions something is working even without checking

that's a surefire way to get bugs

[orchid garden]

im not making a assumption.

[odd ember]

I'm not having this discussion

[orchid garden]

If the project is set to use complex collision, and the model is set to use the project default, and that model only has simple collsion, then the actor, and the camera would pass through the model. its a fact, not one being blocked and one not.

[lusty grotto]

Can someone help with a blueprint problem?

[fleet crest]

Just explain your problem, best would be with screenshots.

[lusty grotto]

Ok

[odd ember]

the pawn and camera do not share collision settings. one could have one set of settings and the other, another. they could be set up in such way that one is going through while the other doesn't

this is especially true for collision, as collision is two way

[orchid garden]

No they don't share collsion settings but they share the collision with the WALL. doesn't matter if one is a complex collision object or a simple collision object, if the wall is simple and the project is set to Complex as default then both will STILL pass through the wall.

[lusty grotto]

I have a solution to the problem, but since i'm a noob at blueprinting, I don't know how to implement it. Apparently it is quite simple, but this is how I did it. I think the problem is, they are in separate blueprints? The solution is, You need to set up a simple branch.
Set boolean to true when you pick up a gun and false when you let it drop.
Then just in your pawn add branch after the trigger and ask every time if it had been picked up before shooting.

[odd ember]

strictly not true as certain things can be set up to work only per collision type:

[lusty grotto]

Heres the screenshots

[odd ember]

[odd ember]

this is especially relevant since camera will usually query complex collision and not simple

but yes just because you don't understand it doesn't mean it's wrong

[orchid garden]

this feels like the other day when you kept insisting the debugger would resolve the var set issue.

[odd ember]

it wouldn't resolve it any more than you would use an xray machine to resolve a broken bone

it would show you what's causing it

[orchid garden]

actually it wouldn't of helped resolve the issue at all.

[cold sinew]

i will work on the Both stuff we have discussed above GL to me

[orchid garden]

just like i stated to you originally. but you kept insisting.

[odd ember]

again, you're letting your assumptions drive your logic

[orchid garden]

no im not.

[odd ember]

which is not how the world works

[orchid garden]

you gave bad advice.

[odd ember]

"use the debugger" is bad advice

lmao that's a first

[orchid garden]

@maiden wadi actually figured out what was happening and the debugger wouldn't of given any light to it. so yes, it was bad advice, do to the fact you couldn't even bother yourself to look at the screenshots showing what was going on before even saying anything.

[cold sinew]

@orchid garden this is the old method of Electrical Cable

[orchid garden]

lol yao, that looks like one of my testing bp's lol

[cold sinew]

its long story 😛

its checking the broken cable location and calculating the bottom and opening gate to set the height of the cable using collision sphere and preview cable when you done it will start spawning the Main Cable Mesh

[sick creek]

cause @maiden wadi is awesome, helps so much 🙂

[orchid garden]

@sick creek yes he is 🙂 great guy

[atomic prairie]

hey, I change the text with a functions, but is it possible to change the font too with a function?

[sick creek]

@atomic prairie

[atomic prairie]

Oh yea ofc, thanks!!!!

[ancient topaz]

@orchid garden @cold sinew Yes, it is glitch. I change Camera and arm, and all is worked. Thanks Guys!

[hollow drift]

how to cast to a child object of a bp? i cant use the master bp to cast to its children

[odd ember]

you should be able to, but either way casting is the same, through the cast node

[hollow drift]

i have random childrens

i cant cast all of them

question is how. is there a bp?

[odd ember]

you could use an interface

[dawn gazelle]

If you have too many classes to attempt to cast to, then perhaps an interface may be a better solution.

[hollow drift]

we already tried

it seems buggy in our version

[orchid garden]

the getclass?

[hollow drift]

you cannot make a execute

the red box

*sorry event

[orchid garden]

ah interface call

[hollow drift]

even if you set up everything correctly

[orchid garden]

4.26?

[hollow drift]

you cannot see the event from the dropdown

no

4.25

[faint pasture]

It's not buggy, you're doing something wrong.

[orchid garden]

interface calls work in 4.25

[hollow drift]

i thought so too

but i could not figure out what i did wrong

[orchid garden]

im using them in 4.25

[hollow drift]

i tried it to do for a half day

think went throught all possible options i could find then.

can do it again, but it will result pretty shure with the same issue

[orchid garden]

and in your class settings you added it to the one thats recieving the call?

[hollow drift]

ye

compiled

restartet ue4

everything^^

[orchid garden]

i had issues getting widgets to do interface calls but actors / pawns seem to work fine for me.

[hollow drift]

idk

[dawn gazelle]

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

[hollow drift]

i tried to add it to a master class

perhaps thats why?

[dawn gazelle]

Just watch the bit about interfaces.

[orchid garden]

nah i have them in my master classes for my objects.

[hollow drift]

ok ill try to set it up again as i know and share it. already read the docu

nop

[orchid garden]

screenshot?

[odd ember]

... you need to override it

[hollow drift]

override?

[orchid garden]

after adding the interface did you compile it ?

[hollow drift]

ofc

[eager peak]

hey, im having trouble removing a single widget from my viewport. i have an invisible prompt to give the player instructions but when i leave the box it doesnt remove from parent

[orchid garden]

if you type in the name of your interface call it doesn't show anything?

[odd ember]

https://docs.unrealengine.com/en-US/ProgrammingAndScripting/Blueprints/BP_HowTo/Interfaces/index.html

@hollow drift

untick context sensitive and see if that works

[dawn gazelle]

If you have a return value you cannot make it an event, only a function.

[hollow drift]

thats all i get

[hollow drift]

oh and you know whats funny is?

if i add a second fuinction

it appears

and if i rename it or delete it in my masterpawn bp it newer comes up again

rip

[orchid garden]

sense its a function you have to do it like:

where new_function_0 would be the name of your interface

[dawn gazelle]

You cannot have a return value set on your interface function if you want it to be an event. Events do not have return values. Create another interface function and do not add a return value. You can then right click on it in the blueprint that is implementing your interface and select "Implement function"

[odd ember]

lmao I cannot believe I missed that

[hollow drift]

ouu

mercii. that make sence

Mynotworkingfunction is now a workingfunction

ty a lot @dawn gazelle 🙂

ah i see its indicating by color

[sonic cipher]

can someone help why my linetrace does that ? thanks

https://gyazo.com/e2d2821498f2211bfeb746d3d1c4dfed

https://gyazo.com/337b206d3947fdc15767a706e4342f4d

i tryed to do a proper linetrace but it did the same

[dawn gazelle]

In that code, you're setting the hit actor's location to the location of the hit.

[sonic cipher]

it is supposed to do that : https://gyazo.com/faf1c202c45f7cffb0cc2065d232654f as you can see at the end the linetrace doesnt work anymore

[sonic cipher]

hmm i see, isnt that what i want ? x)

[inland merlin]

It is what you want

you're issue is due to the fact your trace is hitting the object you're moving

[sonic cipher]

And i want it to touch the ground right ?

[inland merlin]

on mouse button down you should check what actor is under your cursor

then you store that actor in a variable and clear the variable on mouse button up

assuming you clicked on a actor you're allowed to move of course

then on tick if the variable is valid you do a trace ignoring that actor and use it to set the location

[sonic cipher]

I will try thanks you 🙂 i'm not sure of what i am doing i'm stuck for hours on this now lol

[inland merlin]

you'll have to use a proper line trace in order to plug your variable in the array ActorsToIgnore

[sonic cipher]

https://gyazo.com/5808e18ddde3f3c80416d77ad33924be

[sonic cipher]

Like this ? It is not moving :v

[inland merlin]

not exactly

why isn't it connected to the True pin of your branch

[sonic cipher]

Oh yes you are right lol

but strange it still doesnt move

[inland merlin]

did you set the variable anywhere?

[sonic cipher]

and there is an error on the node "set actor location" because i didnt set yeah :v

i can set it next to the linetrace ?

https://gyazo.com/d32b56e029b71e0fb975c2852aeb5e25 i did it like this

and i get this when i get it back again https://gyazo.com/ab8e741f1c838417ab265a819a863eeb

[inland merlin]

I tested it inside my controller

[orchid garden]

hrm... question.... so i have maps set in my project file:

[sonic cipher]

is it working for you ?

[orchid garden]

is there anyway to get 'play in standalone' to load the game default map instead of the editor default?

[odd ember]

welcome to the depths of depravity that is this channel

[sonic cipher]

Lol :v

[earnest tangle]

Shouldn't using the "Enable Input" node make the actor in question receive inputs from the player with the highest priority? 🤔

Not entirely sure why but it seems to be doing absolutely nothing, the input events in the actor aren't receiving any events despite calling that...

[inland merlin]

slight adjustement but it works

[keen seal]

That one's a mystery to me.
Try setting the game default map to nothing and then select NewWorld

Some say that worked, but I just made an empty project and migrate all the files

[sonic cipher]

Omg, thanks you, i made it work the problem was the set of the variable, i had to do a cast inside my widget (where i spawn the wall) and then use this variable :v

[earnest tangle]

The problem seems to be that the actor is not even put into the input stack for some reason...

[orchid garden]

yeah its loading the editor map, i was just wondering if there was a way to make it load the game map instead for testing without switching from my work in progress map.

[sonic cipher]

You are damn fast ahah, is there a way to get inside the Widget to use his Tick ? i'm in my character and it would be better if i use the tick inside the Widget no ? ^^

So i could use the linetrace in the widget that was already made

[inland merlin]

i'll advise to do it in the controller

[orchid garden]

custom timer?

[sonic cipher]

Everything in the controller then

Thanks you, you are the best 🙂

[vivid fog]

Hey everyone! I was wondering if anyone had any guidance on the best way to attach an actor to another actor at a specific location (such as a bone socket in this instance).

I'm working on a horse riding system, and I can use Attach Component To Component to attach the player character's body mesh to the horse's body mesh at specific bone socket called "MountPoint", but then there's no real way to detach it afterwards

I've tried using "detach component" but that doesn't appear to do anything at all. I've even tried destroying the component I attached to, plus the actor (horse) itself, but once I use Attach Component To Component, the player is always stuck in that location afterwards

[viscid shard]

@odd ember i know what Yaw does but nothing i do allows my camera boom to be exactly the same angle / axis as my controller and theres no way to set controller yaw only add

[odd ember]

... add yaw input?

you'd want to do that in the controller, though. there's also set control rotation

which you can break apart and use the yaw of

[quiet token]

Hey Hey! Does anyone know how i POSSIBLY could make a Strafejump like in Counterstrike? I'm too noob and all information i find isnt useful to me.

[orchid garden]

cant you use?

[viscid shard]

no because i dont want to use the controllers yaw can never get the camera right then.

[odd ember]

so what do you want to use then? if it's just the camera then turn off control rotation and see if you fare better

[viscid shard]

so the problem i had with the thirdperson setup was that if i changed how i wanted the camera to act, whenever i changed the cameras rotation the controllers Yaw would be a crazy different direction

[odd ember]

the control rotation controls your camera unless you tell it not to

you don't control your camera by moving your camera

you just do the control rotation and the setup handles it for you

if you want to you can untick use controller p/y/r in the camera or boom settings and manipulate it manually that way

my take is that it won't make a difference and that there are probably other things that make it not work properly for you, e.g. camera lag of some sort

[sonic cipher]

can i cast on a event tick ? ^^

[zenith scarab]

you could yes

[sonic cipher]

thanks

[quiet token]

Hey everyone! I asked this yesterday, maybe someone could help me out here. I want my character to be able to Strafejump like in CounterStrike. As soon as the player jumps he should keep his momentum in the direction he had at the moment he jumped, and can let got of "forward" key. When he presses "left" then, for example, the movement input should move him "forward + left" insted of just "left" so he can use his mouse to make a curve while in air. In simple words, i want the player to make a curve in the direction he's pushin and lookin so he could in fact start the jump and end the jump at exactly the same position. I hope my question is not too confusing.

Somethin like this would be the outcome when i'm not totally wrong. But this is what i want, in fact the player could jump in circles

[odd ember]

set air control to 1 or more in the cmc and call it a day?

[quiet token]

no, when i have air controll on he just moves left in the air

i want the curve

[odd ember]

then I have no idea what you want

[solemn parcel]

So i4ve set an AI Character to 'AI Move To' the PlayerCharacter, works properly. I shot line trace from weapon, which on hit diminish the MaxWalkSpeed of AICharacter. Thing is, once hit, the AI just stops walking, while still rotating in my direction. Any ideas ?

[quiet token]

https://www.youtube.com/watch?v=hMsPf8eSW3k <<<< This is what strafejumpin looks like in cs 1.6

maybe this eyplaines the questions

question*

[odd ember]

debug with a breakpoint and see if it doesn't hit more than once @solemn parcel

[quiet token]

its really hard to discripe

the player is just usin "A" and "D" + his mouse to move in this curves while in air

[solemn parcel]

@odd ember First time i'm using the the breakpoint, what should I look out for ?

Just in case, the damage only applies once

[odd ember]

see what is hitting, resume game, see if it hits again

[odd ember]

so from looking at the movement you could try and allow for limited air control as a function of velocity

it's either that or some degree of air control lag

[quiet token]

I limited aircontrol only for y axis in air, but this is not the same

[gusty shuttle]

What's that node where I can set a Int to Text and add {x} to it to make it read the way I want it to read

[odd ember]

you have to do it as a function of velocity

e.g. if velocity increases, air control increases, same for decrease

see which one works and play with the values

[quiet token]

okay that might be too hard for me, i'm doin this for one week, but thanks for the tip anyway

❤️

[solemn parcel]

@odd ember Everything seems normal, but I got no loop

[odd ember]

I don't think it would be hard to implement, just try with aircontrol = 1/velocity or player speed,

then clamp it if necessary

[quiet token]

@odd ember https://adrianb.io/2015/02/14/bunnyhop.html This would be nice, but i think its a little bit more complicated

[odd ember]

you can find equivalent nodes for all of this in BP

[quiet token]

i think this with the vector would happend if i just tell the game to press "left + forward" in air when just pressin "left", but not sure, it feels kind of the same when i do it manually but this is not the feel i want for players and u dont have the same kind of controll

[odd ember]

slow effect is set to 0

ah hmm

ok do this

[quiet token]

Mhh okay, need to get my head into it a little more i guess, this is too much for me right now ^^

[odd ember]

use the breakpoint, go past the max walk speed node

and check what the value of max walk speed is

[hollow dust]

I'm trying to make a platform that the player can jump through when he is below it, but can stand on top of it when he is above it. think of the platforms in smash bros where u can jump straight through the ceiling and get on the higher floors. what i tried to do is every frame, check if the player's Z location is > than the floor's Z location, and if it IS, then enable collision. if the player's Z location is BELOW the floor's z location, disable collision. the issue is that once the collision is disabled, even if the player is above the floor, I cannot re-enable the collision and i fall back through the floor. can anyone help me out with this? im new and trying to learn http://puu.sh/H3LDy/af4a462fa8.png

[odd ember]

also is process damage a delegate?

@solemn parcel

[solemn parcel]

@odd ember I realised after asking that there was no input value for the slow, meaning as you said, it was set to 0

Thanks !

[rotund basalt]

@hollow dust There are much much better ways of handling that, no tick is required.

Try using collision events instead to check wether the player is below or above a platform by checking the hitnormal for instance

[hollow dust]

I’m sorry if I don’t understand, I’m very new lol
Do you mean put a box collision on the top of it and do OnCollisionEnter: enable the collision?

[zenith scarab]

use player pawn not player controller, because when you didnt set that to true in your custom player cotroller the player conroller won be attached o the player pawn

[rotund basalt]

This is for example how you could retrieve the hit normal

Probably a better way of doing it but im currently tired 😛

You can then check if the Z value is 1 or not then you know its from below or above.

[odd ember]

sweep result can give you the same

[hollow dust]

http://puu.sh/H3LZ5/f13489f1cb.png
still doesn't work. 😦
also, i printed the string of the player controller's Z and it seemed accurate

[zenith scarab]

try the alternative wizard showed, but ake sure ur mesh even has collision

[hollow dust]

ill try that, not gonna lie ive never used spheretracebychannel or that sphere function. i might have to google them and read up on them so i can understand what u did in ur example haha

[hollow dust]

i know it does, because i'm able to stand on top of the platform with the execution pins for disabling the collision cut off. once i disable the collision through the blueprint, i cannot re-enable it

[rotund basalt]

Tracing is a fundamental thing, think of it like a laser pointer.

https://www.youtube.com/watch?v=vje9S5aj15k

[zenith scarab]

try setting the mesh colision not the acftr collision

[hollow dust]

i've used linetracebychannel but spheres seem a lot more complicated

ill try that luis

[hollow cape]

Never a bad time to learn something new

[hollow dust]

you are right 🙂

[proven river]

hey so I'm trying to get this actor tag I put on a box brush, but when I try to GetActor it says there's no actor, am I doing something wrong? there's even an actor part in the properties tab

@hollow dust On a side note. Wouldn't it just be easier to affect the moving pawn rather than everything around it? You'll have less headaches in the end if you simply change the collision profile of the pawn to avoid certain types of objects based on it's own velocity rather than altering dozens of other thing's profiles and making other stuff work with that.

I'm thinking typical side scroller here where you can jump up through objects and then land on them, but still get hit by projectiles. Swapping between a profile that can move through stuff and not move through it, but both profiles would still block like bullets, would simplify your design by a lot.

@proven river How are you getting the actor?

[proven river]

it's a collision with the floor

[hollow dust]

the issue was the function i was using. Set Actor Enable Collision was not the one i shouldve been using. i changed it to Set Mesh Enable Collision like luis suggested and it worked 😄

[hollow dust]

ahh that would make sense. im still really new. fresh out of my first tutorial, and working on my first small game haha. im still pretty clueless about things that may seem like common sense, trying to grind up some experience so i can learn things like that lol

[maiden wadi]

@hollow dust Which will work fine, but you'll have to do that on each and every single actor that you want to jump through. That'll be hazardous to your full design in the end. It's just the philosophy of changing potentially dozens of things vs changing one.

[hollow dust]

yeahh i see what you mean. originally my plan was to only have certain platforms that allow you to jump through them, which would be made into blueprints. but i see that i may have to change my way of thinking

[maiden wadi]

You can still do that. Things you don't want the player to jump through ever can just be block all. Things you want them to go through can have a profile that doesn't block the pawn's capsule normally. This would allow your pawn to jump through it at all times. Then you can switch your pawn's capsule between normal when moving up, and something like block all when moving down. This would make them go through these objects when their velocity Z is positive and not when their velocity Z is negative.

[sonic cipher]

https://gyazo.com/d9f78c1893e9c45a0d213ef51fc77424 any idea how i can stop the linetrace of the mouse ? it set the object location to the mouse but then how can i say "when i click, set the object location here and stop fallowing" thanks 🙂

[hollow drift]

Hi folks. is there a mechanic where we can set up a control unit which checks in which order bp are spawned and checks if those has finished loading befor loading the next bp

[rotund basalt]

How not to name a node : P

[dawn gazelle]

lol

[rotund basalt]

Thats an actual node in unreal

[dawn gazelle]

What blueprint are you in to get that?

Guys, we've been doing it wrong this whole time....

[peak plaza]

Damn, didn't work because of a race condition.

[hollow drift]

can you send me the blueprint please?

pay y a lot

[north bay]

@dawn gazelle thanks i tried it and it works!

[sonic cipher]

Anyone know how i can just drop the object ? i want to set his location when i click but i don't know how, it is still using the linetrace of the mouse 😦 https://gyazo.com/314b622a05862e7a145820944e90f441

[north bay]

Hey guys, II have this multiplayer project where each player collect individual coins, The coins are already individual collected in each Player controller (I tested it with strings and it works).

But now I'm creating a widget (see picture) and want to reference the coin amount per player so I can bind this to the text so it will update accordingly and both players can see how many coins each player has in their widget. I want to make a bind on the text to the coin amount reference from each individual player but I don't know how (The coin amount variable is in the Player controller)

[dawn gazelle]

You probably need to store the coin amount in the PlayerState. If this is going to be an online multiplayer game, player controllers are only available locally and on the server, not to other clients.

[sturdy verge]

Hi everyone, I hope to find a answer here. In case I load a Level Instance, how do I get all Assets in the instance? (I require a specific Camera Actor included in the scene -> multiple Level Instances are loaded and to prevent race conditions I would like to get a camera reference) Thanks!

[dawn gazelle]

When you're increasing the score of the player, you can send an event through the player controller to have them update their widget with the new coin value.

[odd ember]

you don't have access to that in BP

[rotund basalt]

Oops typo

[stable fjord]

https://www.youtube.com/watch?v=6ilTf94qXwc&t=3631s

I am forced to ask here too

[high frost]

I want to implement a pick up system for actors in such a way that a player can only pick up a character when they see (meaning with respect to camera) it and the actor is within some range like 1-2 meters. Also players must observe information about item before they interact with them, i.e. an item name should pop up above it when it is reachable
What is the best way to do it? So far I have only 2 ideas:

1. In the player character add a long collision box on a springarm on eyelevel so that it moves with camera and to handle begin overlap events with interactable actors. This approach would also require me to handle blocking obstacles so that the player couldn't interact with an item throgh a wall and I'm not even sure if that is possible
2. Somehow use LineTraceForObjects or a similar function to actually trace all items. But that would require me to execute trace functions in the tick event or via timer so I'm not sure if that's a good idea neither
   Also I've seen implementations where interactable items just had their own collision spheres spanning pretty wide so that player could interact with them when he is within a radius of the sphere, but I don't really like this approach as it would require to make big collision spheres even for very small interactable items like coins etc

[north bay]

@dawn gazelle Thanks! This is super helpful, I'm still a bit confused with working with a PlayerState. How does it store exactly info for each player and how to use it in general? I'm trying to find a nice tutorial or article or any form of example but its hard to find.

Like I do understand what it does, but never seen any example and I'm a bit lost how to properly use it myself right now

[dawn gazelle]

Each player gets their own instance of it. You can reference a specific player state from their controller.

So when I join a game, I get my player state. When you join, you get yours.

[winged sentinel]

stupid qwuestion but how is a node like this made?

[dawn gazelle]

That's a variable from a referenced object.

In my player state, I have a value called "DefaultAbilities". By getting reference to my player state I can then ask to get that value:

[stable fjord]

@dawn gazelle Did u work with Cartoon Water Shader?

[dawn gazelle]

Nope

[stable fjord]

or anyone here?

[sturdy notch]

Can anyone help me? I for the life of me cannot figure out why I cannot get levels to load in unless I use the console command itself. Nothing within the BP will load my menu main level again. I can use 'open level' from the main menu to get it going, but from my pause menu it hangs and will not load the main menu back again unless I use the console command.

[winged sentinel]

@dawn gazelle thank you i may need to do some researtch myself that helped tho

[odd ember]

@sturdy notch are you trying to reload the same level you're in?

and also are you using any kind of WC

[unborn maple]

so i have an issue. i am making a start button to begin a round it does the countdown, but the button is still on the screen. even after i remove from parent from the timer countdown do i have to originally set the hud widget to remove it self in the place it was made?

[sturdy notch]

I've setup the main menu level to open first. From there it loads a few demo levels to give people an idea of what we have done. In the pause menu there's a button for 'main menu'. The buttons to get to each level are fine, but the button to go from the pause menu BACK to the main menu hangs.

@odd ember WC?

[dawn gazelle]

When dealing with UE4's blueprints, you're dealing with Object Oriented programming. You need to get a reference to an object that contains the value you're looking for. So in your example, "Equipped Weapon" is a variable that is stored in whatever the "character" thing is you have referenced in the top corner of your screenshot.

[odd ember]

you might have to show your logic. WC is world composition but it doesn't sound like that's something you've got going on

[dawn gazelle]

You can set its visibility to collapsed.

[unborn maple]

ok.

[sturdy notch]

Logic aside, I find it odd that I can type into the console 'open <map name>' and it opens, but if I do the same thing (console command in BP) it does not..

[zinc spoke]

Hi everyone. Is there some other possibility (not AI) to simulate input in blueprints? I need to move an unpossesed pawn. For example, i want that my pawn run forward, and if i press the button, he turns right or stop or whatever.. The movement change schoud be based on events. For now i call events by pressing the button. I tried to use a TargetPoint as a Location, but if i use the node "Move to Location/Actor" he dosent move at all. If i use Add Movement Input it also doesnt work. I dont know how to make, that my button will be percieved as pressed for some time. Can somebody help me? Or do you have any idea what i should try?

[unborn maple]

thank you datura that fix it

[hollow drift]

healp

how to do proper level loading

e.g. all bp which are neccecary for the map have successfully loaded and the title screen (done over another map) can move to the main level

[sonic cipher]

Anyone know how i can just drop the object please ? i want to set his location when i click but i don't know how, it is still using the linetrace of the mouse 😦 https://gyazo.com/314b622a05862e7a145820944e90f441

[odd ember]

it should

[quiet token]

Is there a way to accelerate my players character "forward + left" when he's just pushin "left" in air?

relative to his point of view in that moment

[hollow drift]

use add

[sturdy notch]

That's why I'm trying to simplify the logic and add 'print' nodes to see where the hangup is

[odd ember]

do you have cpp access

you might have to debug this on a cpp level since it might be a hangup during loading

[odd ember]

you might want to spawn a copy?

and then just hide the initial mesh

[sonic cipher]

The item that you can see is already spawned, i'm just dragging it with the mouse but i would like it to drop when i click, i only found "remove from parent" for the Widget (that i use to spawn the item) it does work but it's not the right thing to do

[odd ember]

I'll need to see your spawn logic. in my opinion though you'll be better off spawning a copy and killing the original, essentially having the one you drag around double as cursor

[sonic cipher]

I just brb 5 mins sorry

[quiet token]

Mhh, i'm just not able to solve my problem. Since no one was able to help me here, is there maybe another discord like this i could try my luck at?

[sonic cipher]

Okay so there is my spawn logic

[hollow dust]

@quiet token Pakkpakk you mean you want your character to go left of the relative direction of where your camera is facing?

[sonic cipher]

https://gyazo.com/3b592372f002ce0e46163a10ac90f4da 1) I click on a button that spawn an object

https://gyazo.com/52d53fed752173d1785c479dc486d1d1 2) i update his position every tick on the mouse cursor

[odd ember]

so... if you're spawn it like that

[sonic cipher]

And now i'm stuck : how can i stop the object to fallow my mouse when i click :v

[odd ember]

why aren't you just using it to spawn a new one at the position?

ah

I see

you can do that on click again

[sonic cipher]

Hum, i can't set up mouse click in Widget

[sonic cipher]

Click on the button you mean ?

[odd ember]

well no, just click

where do you spawn the widget?

[sonic cipher]

I can't find left mous button in user widget hmm

[odd ember]

the user widget won't help you

[sonic cipher]

i create the widget in my characterBP, when i press E

[odd ember]

it's already done its job

[sonic cipher]

Okay ^^

[odd ember]

cool, that's perfect

so in your character BP

that widget will give you a reference

[sonic cipher]

i'm lucky for once haha

[sturdy notch]

I figured out the issue and got it sorted - when the game if Paused, it will not parse Delay nodes, as the timer is not running. I just needed to disable input and un-pause, then all was well. Thanks.

[sonic cipher]

Yep i have that reference 🙂

[odd ember]

using that reference, you have access to everything inside of that widget

[sonic cipher]

https://gyazo.com/0d475cae9914d0fe41f302b6b8e4d1ae

[odd ember]

including the door reference

so if it's called SpawnEditor then you can do Get SpawnEditor and then Get Door ref

or whatever you called your door

[sonic cipher]

so i just do onclick spawn > then i get the wall from the create widget > then spawn at traceline location ? ^^

I think i get it

[odd ember]

well get that reference first

and then we can talk about options

[sonic cipher]

Yep

https://gyazo.com/fd59a9220782b2013ee6df3fadc19072

like this ?

[odd ember]

well

almost

you're setting that widget

in the next node

so in your blueprint panel

[sonic cipher]

i set the wall1 too ?

[odd ember]

no no

[sonic cipher]

oof

[odd ember]

forget about wall1

for now

[sonic cipher]

okay

oh

[odd ember]

get the ref first

[sonic cipher]

okay

i get the reference that i set

[odd ember]

yes exactly

drag it out from the blueprint panel

[sonic cipher]

i have it ^^

[odd ember]

cool

from this

you want to drag out the wall1 if that's what your door is called

[sonic cipher]

yep haha okay

done https://gyazo.com/9889cc24d862de546e7df1447f50a585

[odd ember]

cool

so we're not done yet

if you go into the blueprint panel and click the SpawnEditor variable

[sonic cipher]

I will have to put conditions to check if i have a door or another object holding i think later no ? because i do not only have wall1 👀

[odd ember]

you will have better ways of handling that later

[sonic cipher]

Yep

[odd ember]

so in your details panel

[sonic cipher]

I always think too munch lol

[odd ember]

scroll all the way to the bottom

you should see a couple of green buttons

with plusses on them

[sonic cipher]

hum

[trim matrix]

Does any of you have any clue on why SetActorTransform does nothing for me, while if i use Add Controller Yaw Input it does work, however i don't want to use latter method as it makes character rotate smoothly which is not ideal for VR

[sonic cipher]

https://gyazo.com/bf024315f0c57df158d2b4498f1200b0 i have this

oh

i have when i click on this

https://gyazo.com/1a859de00903126de62b8da5b1192046

i clicked on the spawn editor

and it does not have green stuff

but this does ⏫

[odd ember]

I see. I assume the widget is where you handle the mouse movement yes?

[stable fjord]

without moving etc

[odd ember]

as in, where the tick movement happens

[sonic cipher]

Yep, linetrace is in the widget

[stable fjord]

I have a following problem

[odd ember]

cool

[stable fjord]

it colliding itself???

[sonic cipher]

Exactly

[odd ember]

so hop into your widget again

[trim matrix]

Even if i do something like this, it moves my character by a tinny bit instead of rotating

[sonic cipher]

Yep 🙂

[odd ember]

create a new event dispatcher

[sonic cipher]

Okay

[zenith ocean]

hey guys! i am a bit new to programming and i try to get footstep sounds for my character. but its not working. 😦 can anyone point me into the right direction? part A (notify with every footstep) is working great. but somehow the information does not get to my main character.

[odd ember]

acutally my bad, you can forego the characterBP stuff entirely here. if it's all taking place inside the widget we might as well finish it within the widget. you can potentially do it this way later but for now it is perhaps a tad too complex. keep the dispatcher though, we'll use it in a second

[sonic cipher]

I didn't made an easy thing there x(

huh

[odd ember]

it's fine tbh you can do it this way and it's not really an issue. but we'll need a few extra things since I thought initially you're using the player controller for your tick

but since you're not everything is inside the widget already and we don't need to take out information

[odd ember]

I'm not sure you can do this through BPI, you might need to bind delegates to make this work

[sonic cipher]

i made it work but as i said it is with the remove from parents, so it does a problem for the next stuff that why i said Remove from parents is not the best idea :v

[odd ember]

that's fine

[sonic cipher]

great news lol

[zenith ocean]

ok, thx. i will look into it. i have the blueprint tutorial from "CodeLikeMe" https://youtu.be/RxPSvjg5OC8

[odd ember]

we can handle all of that. right now you should go into your widget designer, and add a button that fills the entire screen @sonic cipher

[rotund basalt]

@stable fjord Those are some realistic physics tbh 😄

[sand gazelle]

Hey guys, I'm new to blueprints. Can someone break this down for me?

[stable fjord]

yea

exactly

My ears are shaking a bit

haha

@rotund basalt any idea , how to fix it? XD

[sonic cipher]

You want to make a big button so when i click it does an event in widget am i right ? will the linetrace still work trough this button ?

[stable fjord]

this is a Flying Galleon hahaha

[odd ember]

looking at your code, it should

we're converting your mouse location to a world location and tracing from there

not tracing directly through the screen, if you will

[sonic cipher]

Yeah it should work, done it

[odd ember]

cool

so the big button, what's important is that it's collapsed until you click the button to spawn the door

[rotund basalt]

@stable fjord I assume you're using 4.26's water boyancy stuff, tbh I have not worked with it yet so theres little i can do to help, maybe check if some component is colliding with the ship or so?

[stable fjord]

4.23.1

[sonic cipher]

hmm i set it to collapsed then

[stable fjord]

version of water shader

yes

collides itself

[odd ember]

you also want to ensure that it is invisible so that you cannot see even when not collapsed

[sonic cipher]

https://gyazo.com/06f0e3e030f6749b8943b6aad26e4798 🙂

[odd ember]

so set render opacity to 0

as well

[sonic cipher]

i set it transparent we can't see anything ;o

[odd ember]

cool perfect

that works

now

[sonic cipher]

i set size to 1920x1080 will it adapt for bigger resolutions ?

[stable fjord]

it is colliding as fuck

[sonic cipher]

of the button

[odd ember]

in the widget editor, while selecting the button, go down to the bottom of the details panel and you should see a bunch of green buttons again

[sonic cipher]

i select Onclicked i believe ?

[odd ember]

resolutions are a beast on their own, you'll have to handle that separately. let's get the logic working first then you can always adapt it to fit with whatever resolution

correct

[sonic cipher]

Okay thanks you ^^

[proven river]

apologies if this is a dumb question, I tried googling it but I can't find anything, what does the ProjectPointToNavigation function do?

[odd ember]

probably takes the point to the nearest point available on the navmesh, but don't hold me to it

[proven river]

what confuses me is it returns a boolean

and for me it's always false

[odd ember]

clearly you've angered the navmesh gods somehow

[proven river]

uh oh

how do I appease them?

[odd ember]

the return value is probably if it managed to, or not

the projected location is what you should use

[proven river]

I'll be honest I don't even know what a nav mesh is

[odd ember]

it's a simplified version of a mesh that covers all walkable space

useful for stuff like AI

[proven river]

ah ok, that makes sense

yeah I guess it's possible then that my nav mesh is goofed up, I'm imagining it's returning true if it could successfully project it to the navmesh

[odd ember]

correct

though the use cases for it are, uh, niche at best?

[proven river]

I'm just following the vr example unreal gives you, it uses that function

it seems to be working fine without it but ig I'm trying to make sure I'm not missing anything really important

[sonic cipher]

https://gyazo.com/c91196a7a38bb498e516f5868d57d781 okay so i did make it visible when it spawn an object, it print good, now i have to make it spawn when i click the button

[odd ember]

yeah exactly, create a new spawn node and get a reference to wall1

from wall1 use GetActorTransform and GetClass and plug these into the new spawn node

[proven river]

how can I go about seeing my nav mesh?

[odd ember]

press p

in the viewport

[proven river]

nothing happened

I'm guessing I don't have one then

[odd ember]

looks like it

the good news is that you haven't angered the navmesh gods at least

[proven river]

this is true

I appreciate your help, I'm still learning ue4 bit by bit

[sonic cipher]

Hmm seems to work !! i think i can finally go ahead again to where RemoveFromParents stuck me https://gyazo.com/3c15909c8495b0743749a08403870066

[odd ember]

cool

depending on where you want to go with it

you might want to remove the original mesh

the wall1 mesh

since it will still be spawned in the world even if you remove from parent

[sonic cipher]

Thanks you, I was trying to use the cursor to select a mesh then be able to move it, but i already done 70% of the work i think

[odd ember]

I mean this is the general method you'll want to use for spawning

[sonic cipher]

Hmm well i like the first mesh so we know where we set the new one ^^

[odd ember]

the rest is architecture and figure out how to spawn different things from pressing different buttons etc.

[odd ember]

sure, just remember to remove it before you remove the widget from parent

and also

as a bonus

you can do a neat little trick

[sonic cipher]

yeah this is better hahah

Yep tell me 🙂

[odd ember]

if you create a new material and make it transparent, then add a fresnel node to the opacity and add a color node to base color in the material editor, you can apply this material to the wall1 mesh

that will make your mesh semi transparent but show the edges

so if you do that and pick a high contrast color then it'll be like a 3d "placement" cursor

[sonic cipher]

ow looks cool, do i have to add this node in character bp too or in the material ?

[odd ember]

you created the material already?

[sonic cipher]

i show you

okay so, i had a basic material for testing : one click the red popup and you can rotate the object, drag-click you can move the object, but actually it doesnt move https://gyazo.com/6a44d5ce26216d5b08eb183e1547dccf

[odd ember]

when you spawn the wall1 mesh you can apply that material to the reference

using the set material node

later on you can consider making it a dynamic instance material but that's not necessary for this prototype

[sonic cipher]

Hmm actually the material is working good, i will switch to edge highlight one like what you said when i'm done with this dragging system 😛 i try to make this drag working ahah

[odd ember]

good luck

[sonic cipher]

I will do this in the tick of my characterBP, thanks for your help it is very cool

[north bay]

@dawn gazelle Thanks! I made it kinda work with the player state, each player sees their own individual coin amount in the HUD now. The next thing I'm trying to figure out is how to also show the coin amount of the other player in the HUD? (So How can I get a reference from not my own player state but someone elses?)

[proven river]

would anyone mine helping me with my navmesh? I literally just started making one, but I'd like to know how it works

right now I have this weird gap, idk what's causing it

[odd ember]

it's intentional, just showing you where it is on the ground. it's purely an editor feature

[proven river]

ah cool, would that cause this weird thing too?

for clarification I mean on the table

around it looks totally normal

[odd ember]

yes so it's applying navmesh on your table

chances are
