blueprint

[sick fable]

why did i randomly lose the ability to walk

@lofty rapids if you know

[lunar sleet]

Sudden onset paralysis ?

[sick fable]

lol yes I cannot move my legs but I can move the camera

wasd

[lunar sleet]

Did you possess the camera instead of the char?

Or is the cam on the char

[sick fable]

cam on my guys head

bone

[lunar sleet]

Ok, are the events firing at all?

Set breakpoints to find out (F9)

[junior prairie]

I want to apply an impulse to a ragdoll when it gets hit by a gun and have the impulse push the ragdoll in the direction the bullet was travelling, which one of these do I use for?

i.e. if I shot the ragdoll in the face, it the head should move back, if I shoot it in the back of the head, the head should move forward

[sick fable]

ok it is firing @lunar sleet

my game paused when i pressed wasd

[lunar sleet]

Oh ok

[sick fable]

because of the breakpoint no?

ok

[lunar sleet]

Yeah no that’s good I got confused for a sec lol

Do you rmbr what you did last before it broke?

Did you mess with the mapping contexts at all

[sick fable]

I was messing with looking left and right and also I messed with the inputs

on the screen I showed you

[lunar sleet]

Ah that’s prly why

[sick fable]

Yes but I don't know what I did

[lunar sleet]

Well for starters

[sick fable]

I might have changed some stuff from -1.0 to positive 1

[lunar sleet]

The stuff in project settings is the old system

[lunar sleet]

Yeah that’s the wrong spot

[lofty rapids]

those shouldn't effect the enhanced input stuff it's seperate

[sick fable]

ple

oke*

I never touched enhanced though

[lunar sleet]

Unless you’re using both for the same thing

[lofty rapids]

well as far as the event that is in the image is enhanced input

[lunar sleet]

You’re using EIS because that’s what gives you IA nodes

You prly went from a template

So get rid of the stuff in project settings

[sick fable]

how do I get rid of it?

I delete

ok I deleted the action mappings and axis

in regular input

I still can't walk

it messed up after I fixed something here

@lunar sleet

[lunar sleet]

Guessing you don’t have source control?

[broken gazelle]

Why would my sphere sometimes block on a wall on some angles and sometimes it just goes through? Why does the same sphere sometimes block on a pawn even though it is set to overlap only? I'm setting linear physics velocity on the sphere

[sick fable]

no clue what that means but when I pressed a w s d it activated the IA_Move event

[lunar sleet]

It’s an easy way to undo fuckups, should set it up sooner than later, see pinned guide in #ue5-general

[lunar sleet]

Did you play with settings on the char?

[sick fable]

maybe

[lunar sleet]

Like use controller rotation

[sick fable]

yes

I think so

maybe

[sick fable]

idk I think I did that somewhere

maybe in the project settings

[lunar sleet]

It would be on the char settings

[sick fable]

what should I change?

I can't see it

[sick fable]

.

[lunar sleet]

Backtrack a bit

You said IA_Move fires for sure?

[sick fable]

yes

W a s d makes it pause

[lunar sleet]

You have 2 skeletal meshes ?

[sick fable]

no?

[lunar sleet]

Your panel says otherwise

[sick fable]

should I delete one?

1 is not used

charactermesh0

i never used it

[lunar sleet]

You should figure out which one you’re using

[sick fable]

it doesn't let me delete the one im not using only the one i am

ive had it since the start tho

@lunar sleet

[lunar sleet]

Have you changed anything in the mapping context?

[dawn gazelle]

Did you recently change game mode or game state?

[sick fable]

not in ia_move or in enhanced as I never knew about it before you said

[lunar sleet]

He’s able to move the camera on the char but not the actual char it’s weird

[lofty rapids]

when you float around can you see your character like it's just there not moving ?

[lunar sleet]

I’d still get rid of that 2nd skeletal mesh if it’s it in use tbh

[sick fable]

ok i just moved the character spawn higher

and my character just floats

and doesn't fall

that isn't normal right

@lunar sleet

[lunar sleet]

None of it is normal 😀

[sick fable]

Blueprint Runtime Error: "Accessed None trying to read property CharacterMovement". Node: Set isfalling? Graph: EventGraph Function: Execute Ubergraph Anim BP Character Blueprint: AnimBP_Character

I got this error after i restart the engine

[lunar sleet]

Ah fudge

Ik what this is

Your CMC details panel is blank

It’s a 5.3 bug

[sick fable]

Oh ok how can I unblank it

lol

[sick fable]

Also what is cmc

[lunar sleet]

The character movement component

I think the only way is to recreate the char

[sick fable]

oh it does look pretty empty

[lunar sleet]

Yeah

[lunar sleet]

Make a new char bp, copy all your stuff in it

[sick fable]

Can I just make a new char bp and drag character movement?

[hasty shard]

Hi everyone.

I'm a bit confuse... habitually I never get trouble with Interfaces... but now...

On the BP_Lantern itself, start game event if I refer the function control lanthern that work, but on Third_character when I trigger the right thing, nothing come up...

Any idea?

[sick fable]

or no

so I have to make the variables over again?

wait how do I make me the new BP Character @lunar sleet

[lunar sleet]

Right click content browser, blueprint class, character

[sick fable]

yes but how do I make me it and not the old blueprint character

[lunar sleet]

It’ll come with a CMC and skeletal mesh

[sick fable]

that might sound dumb to you

[lunar sleet]

You just change the assets and variables

Copy the code over

[sick fable]

oke so It should just be me when I press play after?

do I have to delete the old one too

[lunar sleet]

You’ll need to delete the old one

[sick fable]

ok is there any easy way to copy the variables

[lunar sleet]

Might need to set it up as default again too

[sick fable]

where

[lunar sleet]

When you copy the code, it tends to ask

[lunar sleet]

Just start with the rest first

[sick fable]

ok

nah none of the variables copied lol

[vocal prism]

anyone got an explanation why the one with higher priority doesnt work when in the documentation is noted that higher priorty goes first

[lunar sleet]

I can’t rmbr off the top of my head but I think you need to reference it somehow or use the player controller to send the msg

[lunar sleet]

#enhanced-input-system

[hasty shard]

The mapping work, I tested it with print string

It just don't call the interface

That weird

[sick fable]

so the way to do It is just select all the blue prints and crtl+c+v it

?

[lunar sleet]

Bp interfaces are weird that way, but where are you setting the bp lantern ref

[vocal prism]

i cannot see the user settings tap, im gonna restart real quick

[hasty shard]

@lunar sleet I never get any trouble before... but maybe I forget something?

The ref is inside the asset on left

Third character blueprint

[lunar sleet]

No no you can’t do that

[hasty shard]

oh

How I should get this reference then?

[lunar sleet]

You want the instance not the asset

So if your char interacts with the lantern somehow, overlap or hit, then you drag off that overlapped/hit actor

[timber sable]

Is there any best practice about what type of component should be the Sceneroot component of a blueprint? Of can you just use whatever?

[hasty shard]

Then, how can I access to the BP_Lanthern function?

[sick fable]

bro I don't know how to properly copy it over

[lunar sleet]

Are you interacting with the lantern in any way?

[hasty shard]

yes, with the input, the lantern is on the caracter... but in the begin, we don't have it

[lunar sleet]

If you’re not that deep just start fresh from a template. And use source control

[lunar sleet]

Wait, it’s a component on the actor?

[vocal prism]

i have checked my settings for the user settings tab but i cannot find it even after restarting the project

[lunar sleet]

What user settings?

[hasty shard]

@lunar sleet yes, it's a companant referencing a blueprint

[lunar sleet]

Umm yeah don’t do that 😀

[vocal prism]

this one that is referenced in #enhanced-input-system

[lunar sleet]

Watch the blueprint communications video pinned here, it helps understand things a bit better

[lunar sleet]

Why are you looking for that?

I told you to go to that channel and watch the pinned tutorials, read the docs, then ask questions if you get stuck, in that channel. After you’ve done all that, preferably

[sick fable]

@lunar sleet ok I copied it over how do I change it to default

[golden pewter]

how can i detect if a nav modifier volume is hovered or clicked

[mental trellis]

In the editor?

Or during runtime?

[hasty shard]

THanks @lunar sleet

[short phoenix]

Say I have a Blueprint that calls an interface and I declared a variable for that interface in the Blueprint. Can I assign that variable somewhere in the editor? I want to connect it to blueprint in another actor.

[drowsy heron]

where can i learn Blueprints from?

[wraith eagle]

The actual unreal website has some good beginning blueprint tutorials.

[paper smelt]

Ik this dont belong in this channel but idk where yo ask. Where can i learn how to make Skinned Decal gore so its realistic and sutch bc i dont wana buy something i could learn and make myself

[short phoenix]

I can see in the details of the actor that calls the interface that I have the public variable for the interface, but I can't assign it in the details view. Nothing comes up as a target for it despite me having an actor in the scene with a blueprint that implements the interface.

[drowsy heron]

thanks

[wraith eagle]

Sure, if you have specific questions the folks are are pretty good at helping around!

[deft pivot]

I have 2 actors. 1 the characters interacts with and the other one that should be destroyed once the player interacted with the 1st actor. How do i set up the BP for it to get destroyed?

https://i.gyazo.com/45cb179f36ca9877b28612cd198cff1e.png

[golden pewter]

how can i detect if a nav modifier volume is hovered or clicked

[edgy ginkgo]

I have a simple question. When in a project in unreal and I click into my game anywhere besides my UI elements my mouse cursor disappears

[fiery swallow]

getplayercontroller -> set show mouse cursor

[kind estuary]

what other alternatives are there for fog of war? what if i dont want fog of war? Should i just cull units that are outside of my units range?

fog of war looks ugly

i dont want a black shadow everywhere in my game

or some weird clouds :/

[lunar sleet]

World partition

[kind estuary]

thats the one that makes a grid and its like lods?

the purpose of that is performance, right?

my problem is not necessarily performance but more like aesthetics

and also gameplay mechanic

maybe it isn't that bad to have the whole map visible?

thats how total war does actually

and stronghold it seems

[lunar sleet]

So make it all visible and use LODs/nanite

[kind estuary]

i noticed when games do that they make they replace the units by symbols at distance

[jagged cipher]

How can i set "can fly" bool in the character movement component in run time?

[woven nest]

Can anyone help me, that why I am getting error of
"pure virtual function being called while application was running (gisrunning == 1)."
when I open any level in my game?

[nimble flower]

what would be the ideal way to set up a system where, once every enemy in a room dies, a bunch of new enemies spawn in set locations?

[short phoenix]

Is there a way to connect a blueprint that implements an interface to a blueprint that needs an instance of an interface in the editor before the game starts? I guess exposing a variable for it only works at run time.

[gentle urchin]

Through a wave manager id say

[short phoenix]

Well it looks like I can pass an actor to the blueprint, not an instance of an interface.

So I cast it to the interface, cast that to an object, and set it as the target of a call to the interface. I did test prints on the initial case to an interface: Cast Failed doesn't print but the other event (I assume for success) does print. However, I don't get any affect on the other actor.

[opaque blade]

Yeah like squire wrote
Give each enemy a Ondeath delegate bind to it and register them in an array before

If called remove from array and if array is empty done

For set locations depends how precise you want them, but for control either designated points or volumes ( and select a random point inside )

[opaque blade]

Not with just BP iirc, but make it instance editable works for Actor
Assigning an actor and cast to that interface is typical for BP only

But maybe check if the instance editable variable can be the interface and allows you to select said actor directly

[short phoenix]

I tried to declare an interface instance editable and I can't assign it from the editor. It was the first thought I had. I've been told it just doesn't work that way.

In the Blueprint, the actor version is instance editable.

And both sides (the thing taking the actor and calling the interface, and the actor that has a blueprint that implements the interface) are doing everything in blueprints.

hey Guys Question,

how can i make the "text Field to keep all the text inside the frame ?

[gentle urchin]

Set wrap rules

[steady night]

auto wrap text ?

yeah that did it ty!

[crude marlin]

How should logic be in event tick, this is from my friends enemy logic , its just lots of nodes with branches everywhere, so when i am about to add something after , i need to figgure out their branch logic aswell. So that my foley sounds wont get interupted.

[thin panther]

You would use an input axis with enhanced input. If your y axis is positive and greater than 0, you are moving the mouse up

[native ferry]

Just remake it from scratch because damn

And all of this is running on tick?

[dark drum]

Personally, I would look at either behavior trees or state trees (experimental) and redo it. Whilst there's no issues doing AI based stuff like in the screenshot, unless its fairly basic AI it just ends up becoming a mess and difficult to expand.

[crude marlin]

ye

[crude marlin]

But how would you make it if not run on tick,
Its kind hard to understand were to put things , dont like nodes. I mean if just coding in C# you just use the methods when needed.

And behaviour trees for ai harder to get the logic there or whats the difference ?

@dark drum @native ferry

[frosty heron]

#blueprint message

[dark drum]

Behavior trees aren't to bad once you understand the basics. Spending a day or two learning them should be enough to create some nice AI behavior. They have a lot of features that work with other elements in the engine. Any AI controller can run a behavior tree.

I personally prefer state trees but as it's still an experiment feature so doesn't have as much support but they do offer a lot more flexibility regarding moving to and from different states an AI might have.

If you're not wanting to use the built in AI tools, you might need to look at making your own system. This would normally require the use of UObjects that would serve as tasks/actions (similar to behavior trees) and then you would create a manager of sorts (Actor component) that would then check what actions it should be performing. (Not recommended for beginners)

As it doesn't seem like you have much experience with AI, I would however recommend just using behavior trees. This would allow you to separate your AI behavior into separate tasks and the tree will be used to control what tasks are performed.

Does anyone know why this would return none even if the action index is 0 or 1? These are gameplay tags.

[dark drum]

Never mind, it looks like its just not showing the value inside the function for some reason. Seems to showing the relevant value on the outside of the node.

[crude marlin]

Oh really nice, why thaaankuuu!

[crude marlin]

Well i know both BH and ST but find the node system BP in unreal clogy when in projects. So its more a matter of convinving them of using BT and dont missuse tick

[steady night]

is it possible to change Text color in a format text ?

[nimble flower]

if my spawn system uses "get all actors of class" to spawn enemies when an event occurs, how would I adjust that so I don't have to make a new class for each subsequent grouping of enemies?

[manic hamlet]

not 100% sure but aint there like "HTML"-Like tags you can use like <red>TEXTINRED</red>?

[steady night]

hmm dose it have to be a rich text style then ?

[manic hamlet]

Havent done it myself just when I saw your question thats what came to mind first 😄 was just a suggestion,no clue if its doable this way at all 🙂

[sick fable]

Can someone help me

my character movement component wiped itself for no reason

And I don't know how to fix it

I tried making a new one and copying everything over but it seemed like it would break everything

[dark drum]

When i looked at setting text colour, you would need to use rich text and as you mentioned a rich text style. I never got round to setting it up but from what I found it's the only way to have different colour text in a single text box.

[steady night]

yy thats what im doing now

[frosty heron]

ask your self how you are spawning and under what condition

you want to avoid get all actor of class unless you are trying to get all actor of the class.
People that just start, over used it because they don't know how to establish communication between blueprints

[frosty heron]

5.3 Bug Rip

[dark drum]

Have you restarted the editor? If you have, if you create a new character BP, do the details show up in that one?

[sick fable]

yes I restarted I am currently trying to copy everything over and fix it all but if this doesn't work my project is basically ruined because I don't know much of what im doing

I am changing all the refrences to the old character to the new one

[nimble flower]

my condition is when the player enters a trigger volume (though I also want to add something that spawns after enemies are killed), and when this happens, the trigger takes the location of every "spawnpoint" blueprint and spawns an enemy at each one before destroying itself and the spawnpoints

[frosty heron]

You need a blueprint that manages the spawning and track the enemies. Call it BP_Spawner for example.

store the relevant information to bp_spawner such as the relevant enemies and spawn point, the rest would just be applying the logic

[nimble flower]

hmm, I def need an overarching manager, but Im wondering what it needs to do

[frosty heron]

it does what it should do

Spawning enemies

[nimble flower]

but how will it know where to spawn enemies if it cant use all actors of class?

[frosty heron]

Depend on how you create the spawn points

is it pre-placed on the map, or created at run time

If it's created at run time then you want to add it to the array of Spawn points in the Bp_spawner everytime you spawn the spawn points

[nimble flower]

rn Im planning on pre-placing them

[frosty heron]

if it's pre-placed in the editor, which isn't ideal imo. Then you can get all actor of class at the start

[dark drum]

Create a transform array and set to show 3d widget. You can then add locations to the array and move them around in the world via the editor. 🙂

[frosty heron]

really depends on the scope of the game, if it's a replayable game with generated spawn points for example, You don't really want to pre-placed it
Instead

Begin Game -> Spawn 5 Points at Random Location -> Add each to the SpawnPoint Array

[nimble flower]

I want specific pawn points for a linear game atm

[manic hamlet]

is there a "default" variable with all the objects that are in "ActorBeginOverlap"?

[frosty heron]

Then you can get all actor of class at event begin play. It's an ok node when not used incorrectly

[nimble flower]

wouldnt that just bring me back to square one though?

like I dont want to spawn enemies at literally all the actors of the spawn point class

[frosty heron]

then don't?

Example of spawning 5 enemies at random point between many spawn points
For Loop (5 times)
{
Get Random element of Spawn Point -> Spawn Enemy at the Spawn point
}

[nimble flower]

that makes sense, tho rn I want to use every single spawn point, just not all at once

[frosty heron]

If you are not fammiliar with array, how to shuffle elements, or to randomise it. Maybe you can start with that

[nimble flower]

like each room will have a set layout(s) of enemies that'll spawn in once I enter it (and occasionally a second/third wave after killing every enemy)

[frosty heron]

it's all about feeding the data. Add relevant spawn points to an array, use that array to spawn the enemy.

[nimble flower]

I rlly need to figure out how arrays work in unreal then

[dreamy mountain]

Hey, anyone know why AI MoveTo is being annoying? It keeps failing

[frosty heron]

for sure, you can't really survive game making w/o knowing how array works imo

[dreamy mountain]

Earlier, it gave an error of 'movement not allowed'

I'm trying to make this barrel asset follow the player

[frosty heron]

Your pic is annoying but you can look at the result

print the movement result just below the exec

[nimble flower]

rn I have a rlly convoluted idea tho

[frosty heron]

you can't make any complex stuff without knowing how array works. especially for something that takes in X number of objects

just start with that and take it slow

start simple, improvise later

[nimble flower]

oh not complex, just convoluted as in dumb

[frosty heron]

Chances are you are going to scrap your entire system anyway once u have better way to do things

[dreamy mountain]

Movement result doesn't do anything; I have it linked to to string and to print string, it prints nothing

[frosty heron]

how are you printing it?

print screen please

[frosty heron]

why the tilted camera

[dreamy mountain]

Sorry for the pics, I don't have discord on the PCs

I'm in college lol

[frosty heron]

You didn't connect the print string

hook it from the OnFail exec

[nimble flower]

I was gonna give the spawn triggers and the spawn points variables, so like if I go in trigger 3, then enemies will spawn at all points with the variable 3

[dreamy mountain]

I get 3

It just spams 3

[frosty heron]

You have to convert the byte to string

[dreamy mountain]

I have

[frosty heron]

that's not what I see

you shouldn't get number

[dreamy mountain]

Unless I'm just dense (probably is)

[frosty heron]

anyway my grandmother is dead, Im gonna pray with my family. Gl on the debug.
Last I checked it's Aborted. there could be number of reason why

[dreamy mountain]

Yeah, I get aborted

[thin panther]

My condolences.

[maiden wadi]

Possible, yes. But it requires C++ and a new decorator class. You can sort of do it with predefined rich text spans. But if you want to dynamically set it in code, you have to create your own text decorator that can take that in and manage it.

[pulsar pulsar]

any reason why it would go through both True and False in the branch? 🤔 i'm stumped and confused lmao

dont mind the mess, I was just trying to narrow it down lol

wait, I might just know why now.

I'm trying to save some corrupt blueprints and I think the old is still being somehow used in memory.

how tf do I delete old corrupt blueprints 😂 the editor crashes when I try to delete them

[stable mantle]

So, I have a question, in my character class I calculated 3 vaulting positions used for my motion warp. Then After getting those I am setting my "bCharIsVaulting" public value to true. ( it does work, debugged as much )

But now I want to do something out of this true state in my blue print, so in my character Event Graph I added this graph but it never triggers looking at the absence of log, any idea what I should change?

[nimble flower]

whats the universal way to call a blueprint within a different blueprint?

[sick fable]

Can someone help me

my wasd isn't working properly

W is making me go right S is making me go left

A is making me go backwards

D is Making me go Forwards

[versed sun]

swap the X and Y

[peak wigeon]

@Kiro #enhanced-input-system

[stone field]

"There are many ways to skin a cat"
References. Events. Interfaces.

[sick fable]

well I can walk backwards and forwards normally

but left and right is still inverted

after I did that

[nimble flower]

just like, if I have the 1st blueprint with one variable, and I want to set the 2nd blueprint's variable to match the 1st, what would I do?

[stone field]

https://docs.unrealengine.com/5.2/en-US/how-to-use-blueprint-communications-in-unreal-engine/

[versed sun]

then take the y pin and multiply by -1

[nimble flower]

ohno it long ty

[stone field]

It goes through a lot of different scenarios

I am personally a big fan of Interfaces

But it depends a lot on the use case

[nimble flower]

that makes sense

[thin panther]

You tend to cast when inheritance makes sense. And use interfaces when interaction needs to be class agnostic. I.e. interaction can happen across many base classes, so should be an interface. Shooting is only going to happen with weapons, so doesn't need an interface

The blueprint communication video is pinned here too if you prefer video format

[nimble flower]

damn there's so much

[echo storm]

Hello, I have this blueprint class and want to create child blueprint classes of it where I can edit the RGB values in the timeline to have a custom colour for each child when the interface function triggers, how can I do that?

[lunar sleet]

Right click create child

[echo storm]

Yes but in the child class the blueprint event graph is empty. Can I edit the timeline from there somehow?

[lunar sleet]

No but you can override the event iirc

[nimble flower]

how would I change the variable for every object in a class, or cast to an entire class at once?

[lunar sleet]

Use the resources we just gave you

[nimble flower]

im lookin bruh

[echo storm]

How do I do that? Just add a new timeline that's connected to the event?

[lunar sleet]

Either that or have a standard track and multiply it by variables so you can change them on each child

Not sure that’ll work for RGB values tho 😅

[echo storm]

Hmm okay thank you

It feels inefficient to create a new timeline when the parent already has the timeline

[versed sun]

You can have the track control the alpha, and outside the timeline you can lerp colors

[lunar sleet]

Ooh nice

[echo storm]

Ohh so basically having 3 lerp nodes in that case then (one for R, one for G, one for B)?

So I can switch from one colour to another

Oh wait no I can just have a vector lerp to do it all in one node

[echo storm]

Thank you, that's really helpful!

[nimble flower]

how could I get the blueprint to not interact with a blueprint, but a specific object in the scene without the two overlapping

[lunar sleet]

An object is an instance of a bp. A cast checks if an object ref is of a certain bp class and then lets you access its insides. It takes a bit to understand this stuff and that video really does help. Ik it’s pretty long but if you don’t understand these bp comms basics you won’t get very far in Unreal

[nimble flower]

and someone said the video is pinned?

did they mean the live training?

damn 2 hours okay

well it does seem important

rn I found a workaround for my specific issue (switched to using gamemode bc that has rlly easy referencing), but I'll def watch this later this week, ty

[echo storm]

Blueprint Communication is essential to understand, I only recently learnt how it works too

https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/ActorCommunication/

[nimble flower]

its so weird rn bc i've been super comfortable with anything that involves the player or collisions, but now that I'm reaching something that has neither i *was at a wall

[echo storm]

This page has a quick-to-read overview of how you could communicate with other Blueprint Classes

[nimble flower]

is there a way to have a blueprint check when a variable reaches a certain amount, but not when its steady at that amount?

like if I reduce something to 0, it'd only trigger once and not for every frame that it's at 0

[jade lintel]

do once?

[echo storm]

You could dispatch it as an event when it reaches 0

(I don't know if that would be the most efficient way though, so someone correct me)

[nimble flower]

oh ig I could use events yeah

[cunning vapor]

I've done the tut - run into some problems I can't seem to fix -- but thanks for the link on it ! 😛

[nimble flower]

do once seems neat as well but I want to do it more than once

cause Im tracking how many enemies are left, and when that number reaches 0 I wanna check if another wave of enemies is scheduled

[versed sun]

Do N
might havesearch Flow Control

Hold N and click on graph

[nimble flower]

wth this looks cool

[random solar]

Okay I'm going to do it this way but instead of adding a black box i'm just going to add a sizebox and increase padding for every 1000. Question is should I use a for loop or should I just do
if stam consumed == 1000
{
set padding for sizebox += 7
max stamina -= 5
stam consumed = 0
}

[tight pollen]

someone can help?

[versed sun]

I wouldn't do padding, just Set Width Override on the Sizebox
then keep track of stamina consumed, and update as needed
I dont see a use for a For Loop

[tight pollen]

I don't know if I clearly stated what I need

[versed sun]

nope...

[random solar]

How would I do every 1000 units of stam consumed for the branch condition?

would it just be what I wrote which is if stam consumed == 1000 then reset to 0 after?

[versed sun]

not reset to 0, Remove 1000
What if you are at 999, and spend 200?

[random solar]

That's what I meant, my bad for how I phrased it but yeah its more like
if stam consumed => 1000

stam consumed - 1000

[versed sun]

Not tested or anything

ballpark idea of code

[tight pollen]

if a connection to other actors already exists, I don't want to execute the function for that connection. e.g. the key (actor1) is connected to: actor2, actor3, actor4 and if the next key (actor2) has actor1 in its values, it will ignore it and go to the next values ​​for this key

someone can help

?

or maybe there is a better way, instead of using a Map variable

[dark drum]

What do you mean by a connection? How are they formed? How are the connections stored?

[tight pollen]

I simply store the references of actors that have been linked to a given actor and check their position on an ongoing basis and at any time these actors can be removed from the value

I just want to not execute a function if it has already been executed in previous actors

[lunar sleet]

How do you store these references, just curious?

[tight pollen]

all is stored in gamemode

in Map variable

[lunar sleet]

I mean how are you getting them

[sick fable]

How can I make the delay only after it has been triggered

So it gets triggered and it can be next triggered in 60 seconds

[lunar sleet]

If this is for an #gameplay-ai it might be best suited for the cooldown feature in behaviour trees

[sick fable]

yes for an ai

After It gets hit it is mean't to run away but I don't want it to repeat the running away event every hit because It will make it look jitery

[lunar sleet]

Set a bool to false until the run is complete and check for that bool before running every time the function is called

[tight pollen]

it's complicated

sorry 😄

[tight pollen]

I just wanted you to help me with this ;p

[sick fable]

Thank you

wait why is this not changing it after I shoot

It should change it to true until it is done running ?

[random solar]

I'm not quite sure how to use set width overide so thought it might be better to just increase padding instead. I'm not sure how to link it to the size box though

[sick fable]

@lunar sleet

[lunar sleet]

Set a breakpoint on it and see when it fires

[tight pollen]

someone can help?

[sick fable]

only on the Ai move to

not on the boolean

it doesn't break on the is fleeing

[tight pollen]

i set reference when actor spawn

[sick fable]

but I put it on both to check

[lunar sleet]

Ok, set the bool to True right before the move to node and back to false when it’s done

[tight pollen]

and the player connects them together by clicking on them

[lunar sleet]

you should prly answer patty’s question: #blueprint message

[sick fable]

ok think that worked

thanks

[nimble flower]

right now I have a system so when you die you return to your last checkpoint, but I was wondering if there would be a way to just reset the scene entirely, with the only change being the player's new position?

[tawdry surge]

Game mode has a reset level function and all actors have a reset event (which fires when reset level is called) that you can override

[tight pollen]

I want something like this

I just don't want the connections to be repeated

(this is Map with Array)

[random solar]

Got an issue where I'm trying to reduce the stamina bar width but doesn't seem to work, In the video you can see the stamina value does a jump but doesnt have the bar itself move. The issue might be because I am using another blueprint to host all of my widgets so the width overide might not be following through but the stamina bar value is

[nimble flower]

what event would be death plane? like if I wanna reset the level when I hit the kill Z, how would I do that?

[tawdry surge]

I just override the end play event of the character and use that to tell the gamemode to spawn default pawn at transform and reset level

[tight pollen]

i made this

there cannot be an identical connection

[nimble flower]

where do I find the end play event of the character?

[tight pollen]

but I guess it's not good in terms of performance :/

Can anyone recommend a better solution?

[tawdry surge]

It's a dispatcher you can bind to which is called when an actor is destroyed

[nimble flower]

would it count as being destroyed if I'm using the "open level" function?

[tawdry surge]

No.. the gamemode dies then too. You'd have to use a save game object or the game instance and grab the info on construction or begin play

[nimble flower]

oh weird

[frosty heron]

<@&213101288538374145>

[nimble flower]

so now the checkpoints work, but the player starts at the default checkpoint value instead of the player start value which is kinda weird

[tawdry surge]

I have a check to see if the checkpoint value is 0,0,0 and if it is, then use player start otherwise use the checkpoint.

Could also use player starts and give them name/tag, then you can use that to pick which one they go to as well

[nimble flower]

how do you do that?

wait im dumb

[pulsar pulsar]

Still having this issue. Not sure what's causing both True and False to go through

[lofty rapids]

wdym both ? the execution shouldn't go through both at the same time

[pulsar pulsar]

I have prints after True and False. Both prints gets printed upon passing the branch

[lofty rapids]

well your branching in a forEach so maybe one is true, one is false

[pulsar pulsar]

I just removed my Does Implement Interface check and manually set it too true and false. Prints for both when the condition is true and on False only the false print gets printed.

[pulsar pulsar]

Hmm. Well, its for a door so it's only a single action when pressing F

[lofty rapids]

Well theres pretty much no way it would go through both

a boolean is either true of false

it most likely because it's in a loop and your seeing two different looped values

[pulsar pulsar]

Actually, I get double prints if I manually set the condition to false. So maybe there is something with the forloop as you said. although.. In my old (now corrupted) blueprint where I first had this function, I didn't have this problem.

[lofty rapids]

well your getting overlapping actors and looking for one that implements a certain interface

so if there is more than one actor overlapping it will run for all of them

idk much about interfaces, but your looping over all overlapping actors so if there is more than one you will run it that many times

[pulsar pulsar]

it's just the door and the character currently

[lunar sleet]

Print your array elements

[patent wasp]

I have a widget on the screen and it goes to this when my character dies. Telling it to add again to viewport doesn't put it back, how can I fix this?

[pulsar pulsar]

I'am. Only getting the door.

[lunar sleet]

Show code

[kind estuary]

So we use this to get a data table. How do we do the same to get a specific data asset?

[maiden wadi]

Make a variable of the asset's type, and populate it.

Can also make static library functions as getters too.

[lofty rapids]

are you seeing "should now interact with" ?

[pulsar pulsar]

correct

followed by the door name

[lofty rapids]

is it not interacting ?

[pulsar pulsar]

It's fully functional, it's just bugging me lol. I guess it's not the end of the world but as I had it not double printing before it was just annoying me.

[lofty rapids]

so it also prints failed to interact ?

[pulsar pulsar]

yesss

[lofty rapids]

probably because there is another thing overlapping it

[nimble flower]

is there a solution to ai breaking?

[pulsar pulsar]

wellll

could be the landscape component? surely not

[lofty rapids]

i wouldn't worry about failed to interact, that's just because you have something overlapping that does not implement interface

not sure what it could be, but that's why you do the loop and check to only interact with the things that use that interface

[pulsar pulsar]

yeaaa I guess. Cheers tho! It's working atleast 👍

[kind estuary]

ah so maybe is better to use data tables because it doesnt need any variable

i have a hard time understanding the difference between data tables and data assets

they seem to be the same in terms of use

except data tables are more useful

[maiden wadi]

Why is having a variable a concern?

And they're really not. Data Assets are a lot more useful. Datatable is just a list of the same data repeated for different keys. A data asset is like one row of a datatable, except that it's a lot more dynamic. It doesn't require a predefined struct to hold data, it can hold anything you want. It can also contain functions to manage that data. You can also use a data asset similar to a datatable by just putting a Map of Key/Struct in it.

Datatables have their uses, but they are not more useful.

[kind estuary]

It can also contain functions to manage that data
ah thats great

well but, it does need a struct

[kind estuary]

those are great tips

or i can use an array in it

and put all my character names in it

[dark drum]

Using overlaps for determining interactings can be troublesome at times. If you every decide to switch to a trace based system, this tutorial will set you up. There's even follow up tutorials for different types of doors. 🙂

https://youtu.be/yvRZVX_HD3E

[pulsar pulsar]

I have this for my light sources ^^ I may switch that to my doors aswell tho

[dark drum]

You should make sure you use the same system for everything the player can interact with to help prevent weird issues. 🙂

[pulsar pulsar]

that's true. I'm currently not making a game or anything though. Merely just learning

[dark drum]

As an FYI, one of the main issues I've had with using overlaps for interacts is when you have a few close together. I find using traces easier to handle as it's what the player is looking at.

[pulsar pulsar]

Ahh yea, you're right. I might aswell change tbh, do it properly from the start 😎

[remote meteor]

i would make an InteractComponent to handle sorting of those "few close together" to select which one exactly to interact, but then, i was making a top-down game

[dark drum]

I'd still use traces though. If you don't need pin point accuracy, you can do a 2nd, smaller sphere trace and then just get the closest to the end point of the first line trace.

[kind estuary]

https://i.ytimg.com/vi/jDvIwq8c9BY/maxresdefault.jpg
How are these farm tiles done?
Are they planes with textures? Or is there something more tricky about it?

[remote meteor]

not exactly when i needed their name and info to show up instead of just "interact"

[wild moth]

the way you get the object to interact with doesn't interfer with that

if you use a trace, you can trace at specific intervals

to find the current object the player is looking at

and display information from it with UI

[remote meteor]

well, in the end i use overlaps and traces to check they are behind an obstacle

[nimble flower]

if the nav mesh is just f*cked up and you have no idea why what do you do

[pulsar pulsar]

I made one line trace that the character uses all the time that I can refer to when needed. I dont suppose one constantly would be bad?

[remote meteor]

for increased responsiveness, you would have to trace at small intervals anyway

[maiden wadi]

@kind estuary To give you a kind of idea of how you might implement both. Just depends on your needs.

I have a bunch of items. Weapons, crafting items etc like coal or iron ore. Right? These are all individual DataAssets. Cause weapons need a lot more data in them than a Coal item. Coal is largely just a mesh, an icon, some association tags, descriptions. Weapons need all of that, plus defaults for their stats, associated abilities, etc etc. The amount of data differs wildly and putting all of that in a struct would be a great waste of space for a lot of smaller crafting items.

But crafting can take any item. Maybe I need a recipe for an Iron ingot. Or maybe I need three recipes for an iron ingot. Maybe I have three different forges and each processes iron a little more efficiently, so I make a table for each forge to house their own craftable recipes. Those tables can reference the items like coal and iron ore with amounts required and output their results. This data is ALL the same. Regardless of how you structure it. You have an array of input items, and an array of output items and some description data thus it's easier to put it in a datatable. Though you could also put these in a dataasset with an array of structs.

[wild moth]

Datatables are easier to add/edit/manipulate and pull data from

if for example you need to list all recipes/all entries in that table/etc

[maiden wadi]

Right, but as structured above, it depends on the data set you're working with. If the data is all the same, structured into a struct, datatables are great. If you need a more dynamic set of data while identifying something, it's not so great.

[sonic crest]

rookie question, how can I grey out the Code Required String??

[remote meteor]

grey out as in make it non editable?

[maiden wadi]

Easy in C++. Can't remember if you can do that in BP only.

[remote meteor]

i dont think you can do that in bp 🤔 except hiding it in advance menu or something

[lofty rapids]

weird they are both the same name

[dark drum]

That video I sent shows how you can set one up on tick or at an interval. 🙂 For something like an interaction system tick is normally fine.

[true igloo]

This Timeline works fine, it animates the UI elements as needed. But, I want to stagger the animations. If there a way to delay each element of the array. I don't see a way to adjust the float curve evaluation of a timeline. I could do something super convoluted like switch statement the index with a buncha different curves, and if that is what I need so be it, but maybe there is a better way?

[wild moth]

There's an entire system for animating UI, you don't need to use a timeline

[maiden wadi]

I'm sort of concerned about seeing a Timeline controlling UI. Why aren't you using a UMG Animation track?

[lunar sleet]

#gameplay-ai is better suited for this question but depends on what you define as the navmesh being f8cked

[true igloo]

Honestly, cause unreal is a vastly complex engine and often times I unknowingly overlook best practices with in the engine even though I make an effort to do things the "right" way. I guess I will look into using the UMG Animation Track.

[sonic crest]

alright, thanks

[sonic crest]

and yes

[sonic crest]

thanks

[maiden wadi]

UMG Animations are basically the same as a sequencer. You can get and affect everything internal to that widget. You can also make tracks that evaluate every frame to run an event that you can do stuff on to use for more dynamic animations.

If your Inner widget there is all the same class it can be fairly easy to put an animation track on it with like a 1s start gap. I did that with some vertical boxes housing buttons. The buttons held the animation track, animating themselves. When the widget was brought up, it just ForEach loops over all of the children in the VBox, and based on the ForEach loop index, multiplies that to start the animation track closer to the 1s gap mark. So you get a ForEach loop that instantly runs to start a lot of animations. But each animation plays starting from a different start point on the anim track. Makes it look like they're delayed but without the hassle of actually doing that.

[kind estuary]

thanks. though its quite confusing. So let me see if i understood it.
So having a data table for units for example can be innefficient. Because the simple basic melee units require less data. Whereas if you have archers, and knights they will differ with their properties. So to have them all in one data table, all the basic melee units must also have information about the archer and knight type, even if they have no arrows, they must have a reference for the arrow mesh.
Thats correcT? And that means its a waste of space.
But then i lost it on the recipes. So you would create a data table for each different unit class ? Or you would create a data table that can have a reference to each different unit class?

You have an array of input items, and an array of output items and some description data thus it's easier to put it in a datatable. Though you could also put these in a dataasset with an array of structs.

And here im GG too. Where do you put the input items? An array of input items? In the data asset? Or the data table?

[maiden wadi]

Here. This might help a little better to actually see it. I made a few assets. The DataAssets are made out of PrimaryAssetLabel types, but I personally would make these out of a PrimaryDataAsset from a C++ base and set them correctly in the asset manager. But for a BP only this will work okay.

There's two structs. One has two arrays of the other. Thes represent entries and the counts. For requirements this is how much of the item you require. For output this is how much of the item you would get for the recipe.

Then there are two datatables. I would give these two my forges so they can look up what data they need for their own crafting. The first datatable only has an iron ingot recipe. It's a bad forge, takes a lot of resources to make one ingot.

The second table has a better iron ingot recipe, and a sword recipe where you can craft a sword from the ingots you've made.

In this particular case, these crafters would need to interact with some form of inventory to get their requirements and output the results.

In the case of units. It would be much the same to create unit types out of a data asset. Specify their meshes, skins, abilities, actor class, etc in an asset.

Then make a table where you can create these units from a barracks or other buildings. Maybe you upgrade your buildings for cheaper unit costs. Can just make a table for each building tier that costs less and less per unit.

[wild moth]

This is a great modular way of handling it, just an addition depending on usecases you could set these as classes/inheritence (BPs) instead of data classes

[wild moth]

A suggestion/idea (depending on recipes of course) but instead of having a data table per building, you could have a single data table with ALL recipes and then list the recipes each building can craft in their respective Struct/DataAsset/Datatable Entry where you define each building's info

[vernal snow]

Howdy there, i'm attempting to create a little slide mechanic and using some blueprint to try and make it a automatic stand up if there is nothing above:
Now the issue currently i find is that i cant get it to "slide" (Add velocity) to the direction the camera is facing, i've messed around with the Forward Vector to the Velocity node a bit but it doesn't yield the intended result (IE Add velocity to where the player is looking) and was wondering if anyone could throw a bone or maybe help.
Thanks for the time.

[lofty rapids]

you tried the camera, forward vector * SomeValue ?

[vernal snow]

No actually, thank you that worked i mainly used +(Value) because i thought the *(Value) may mess up stuff.

[drowsy steppe]

hey guys, where can i ask for someone to help me?

[kind estuary]

thats awesome. will try to make something based on that. thanks a lot.

[lofty rapids]

usually you find the proper section and ask there

[drowsy steppe]

well I'm trying to use an interface but I'm unable to, can i ask here?

[lofty rapids]

you are using blueprint ?

[drowsy steppe]

yes

[lofty rapids]

then probably it would make sense, i usually just pick the closest and ask you would probably be redirected to the right place if it's not correct ig

[true igloo]

What is the best practice for animating Camera Modifiers. Basically I want a reusable animated camera modifier. in the modifier I can animate it with a Timer that ticks up from the provided delta time. But that Timer value does not reset and the value isn't accessible from what I can tell. Is there way to do this with the nodes inside the modifier so it animates the values then resets?

[drowsy steppe]

So guys here's my problem (I'm quite new at this).
I did a system with line traces and an interface to interact with objects and i added a widget (the letter E) that shows up whenever I can interact with an object that is interactable. Everything works properly and it is set like in the screenshot.
Now I want to add a feature where if you enable the option on an item whenever you pick it up it shows up in front of the camera and you can inspect it and rotate it.
I created a new function in the interface (with an output as a static mesh) I'm already using (second screenshot) and I tried adding the message in the thirdpersoncharacter blueprint where when the object in the scene gets hit from the line trace and after interacting it should set the mesh i put in front of the camera as the mesh of the object i picked up, but it is doing nothing, someone knows why? I hope I was clear enough and I appreciate anyone trying to help me

[lofty rapids]

Is it printing hello ? @drowsy steppe

[manic vessel]

Im Not sure why My Items are not being removed from this actor component inventory's Array, What did I do Wrong?

[drowsy steppe]

no, even if i put it earlier. Is the reasoning behind this right?

[lofty rapids]

well the reasoning is if it's not printing, then it's not firing

[drowsy steppe]

yeah i mean the reasoning behing the logic I'm trying to apply

[versed sun]

On your Remove Item Event, see it the Removed Item is valid

[lofty rapids]

maybe does implement interface is failing, print string out of the false

[manic vessel]

Seems to be valid as the print text is working

[drowsy steppe]

it prints nothing 😦

[lofty rapids]

one thing is you don't change number of items, not sure if you need that but it looks like if you want to keep the number of items you should get length and set it again

[lofty rapids]

how about out of the true, does it print ?

[versed sun]

Well, Check to see it the array Contains the Item

[drowsy steppe]

no

[lofty rapids]

then it's not executing

[versed sun]

Also, the array length Print is printing on the add item ?

[drowsy steppe]

i don't understand, it doesn't print even if i put print string before the interact event which is working because i can interact with my items

[versed sun]

and , you aren't deleting the item before removing it from array ?

[manic vessel]

Yes Im printing the array here when an item is added.

[lofty rapids]

well if you put a print string on the white lines (execution) and it doesn't print then it's not running, but also you want to make sure it's when it should be ran

its obviously not going to show right off the bat if it's on a click action or something

[drowsy steppe]

but i don't understand because what happens after gets executed as i can interact with my items, and that needs the interact message to be possible

what am i missing?

[manic vessel]

a separate spawner is adding the item to the actor component array when the player overlaps it. then I cycle the array and spawn a actor in the players hand . when I drop it thats when I need to remove it from the array

[drowsy steppe]

i disconnected interact and everything is working the same, i am confused

[lofty rapids]

are you compiling ?

[lofty rapids]

maybe your in a different bp ? some sort of copy or something ?

[drowsy steppe]

yes, i must be missing something really dumb

[versed sun]

Try on the Remove event, seeing if the array Contains the item, If not then For each Print the contents of the array

[drowsy steppe]

I disabled everything on the first input action and everything is still working, i'm really confused

[drowsy steppe]

Yeah there something going on in the background because i disabled everything and it's still working

[lofty rapids]

there must be other code somewhere running

[drowsy steppe]

yeah looking into it

[manic vessel]

not printing here so I assume its not even in the array?

[versed sun]

alright, getting somewhere
See if it is valid before adding it to array

ohh...

there is a Contain node for arrays

[versed sun]

And do this before and after adding to array

[drowsy steppe]

found it

[manic vessel]

On cycle array in player BP im destroying any valid helf actor and spawning a new one from this array. and setting it as the held item. but that is the same thing I am telling the array to remove when I drop it. the cycling of items in the hand is actuall working ok but they are just not being removed 😦

[versed sun]

ahhhhh, so its not the same exact item, its a copy ?

[manic vessel]

Contains was not true 😦 Must be adding items as a different actor

[versed sun]

You might want to switch the array to a Class Ref

[manic vessel]

yeah. I will try that

[versed sun]

yes, that should do it

[manic vessel]

just incase child actor issue?

[versed sun]

not child actor

[manic vessel]

instance

[versed sun]

the array hold a list of EXACT actor, once you destroy the actor in your cycle , its ref in the array is not valid/ gets destroyed or somehting

[manic vessel]

I get it . I Made sure to destroy the actor after removing it from the array.

[versed sun]

You should change your array to keep track to what Class the actor is, not what actor it was
Change that variable type to Class ref like this

dosnt have to be "Actor", use whatever your blueprint is

[manic vessel]

Yeah I already have one setup, But working with arrays is still a bit new. The add and add unique is always a point of contention

[lunar sleet]

Like you don’t understand the difference?

[abstract oar]

Is it normal that OnBeginOverlap events don´t fire all the time, even if it should?

[manic vessel]

I do But One Time I didn't ; )

[versed sun]

It wont fire if its already overlaped before

[lunar sleet]

Use getOverlappedActors and iterate

[faint pasture]

When does it not fire?

Begin Play?

[abstract oar]

Can I use it when I want to make a bullet?

[abstract oar]

When the bullet hits it target, but sometimes it fires

[lunar sleet]

You should use begin overlap if it’s a projectile travelling through something

[faint pasture]

Yeah I'm not sure what happens with the stock ProjectileMovementComponent, it's pretty ass IMO

[lunar sleet]

If it doesn’t fire check your collision, if you’re doing like a sphere or similar shape it can have weird effects

[abstract oar]

Collision is okay, it fires, but not on every hit, even if it clearly hits the target

[lunar sleet]

Are you blocking (hit) or overlapping

[abstract oar]

overlapping

[lunar sleet]

On the collision settings I mean

Not the event

Like check settings on both objects, the bullet and the target

[lunar sleet]

Need to see the drop-down (all the checkboxes)

[abstract oar]

Bullet

[lunar sleet]

What object type is your bullet

[abstract oar]

Target

[abstract oar]

Actor

[lunar sleet]

No no I meant collision wise

Looks like you set it to vehicle tho

[abstract oar]

Yes

[lunar sleet]

Check ✅ the generate overlap events on the target

[manic vessel]

Works Great ! good call on the Actor class.

[lunar sleet]

I still don’t know why my projectile phases through Event Hits at certain velocities and fps. Temporarily switched it to overlap to fix it but it’s not accurate enough for what I want

[abstract oar]

Oh

[abstract oar]

Thank you, that fixed it 👍🏻

[manic vessel]

Wonder if CCD would help

[versed sun]

Nice!
The downside to Class is it wont retain info about weapon (Ammo, durability, mods)

[lunar sleet]

Hmm I haven’t thought of that outside the context of AI movement. I know the CMC has it, is it on the PMC tho?

[manic vessel]

CCD=Constant collision detection on the collision settings I have no idea if that will help its a shot in the dark

[faint pasture]

Is it important that your projectiles can be hit by another projectile?

[lunar sleet]

No, not really

[faint pasture]

I'd just lose the projectile movement component and do your own

[lunar sleet]

Maybe I’m thinking of the wrong spot I can’t check rn

[faint pasture]

just line trace on tick

I like it a lot better

[lunar sleet]

Like cpp code my own PMC ?

[faint pasture]

you can do it in BP.

Tick -> update Velocity (mostly gravity but homing too) -> calculate NextPosition -> trace from CurrentPosition to NextPosition -> process hits

[lunar sleet]

Oh neat

[versed sun]

do you have Sweep on? Doesn't that trigger Hits ?

[faint pasture]

no collision on anything in the projectile. It's just a thing that moves through space tracing every frame. Cool thing is it will devolve into a line trace if you turn up the initial velocity high enough

You don't even need projectile actors for this, projectiles can just be structs in a subsystem or gamestate or whatever

depends on your needs

[lunar sleet]

Oh the overlap? I haven’t checked if it has that

[faint pasture]

This is exactly what ProjectileMovementComponent does but it relies on collisions with the collision body, not on doing traces

[lunar sleet]

The event hit doesn’t have sweep, that’s on traces iirc

[versed sun]

I was thinking on this

[lunar sleet]

I’ll try this when I get a chance

[lunar sleet]

Oh I’m using velocity not set location rn

I set it to X:500 by default, which becomes Y in local space at runtime but either way

Dropping it to 400 made the event hit work at 60fps, but 30fps and it’s gone

At 500 only 120fps registers it

Maybe my disc is moving through frames like Neo 😅

[manic vessel]

Normally When Using actor I can use reference to self, Here with the Actor class how would I do the same, as this actor is removing itself from the player

[versed sun]

Quick Inventory>Get WeaponRH>Get Class

[lunar sleet]

Get class

[manic vessel]

this ? method

[lunar sleet]

That should work no?

[manic vessel]

I think is should. I will test

[versed sun]

yes on the class, but instead of self you want the weapon ref?

ahh, it is self

nm

[lunar sleet]

I’d tell you to remove that medal but it’s a Super:: so I’ll allow it 🙃

[versed sun]

haha

[manic vessel]

works Great

[versed sun]

was doing it as you said it

[lunar sleet]

Noo

Don’t remove supers, you don’t get them back

[mental trellis]

What?

Guys I had some strange issue while attaching NPCs to vehicle mesh. They seem to attach to the actor but not the mesh.
I wrote about it here. Please help !

Super reactions

[mental trellis]

Oh.

[kind estuary]

took me a while to understand it. basically the data tables have an array of recipes to make weapons. and each recipe is a data asset so that means each weapon fabrication is unique and can be customized because the data asset recipes can be made specifically for that one. thats very smart and versatile. i dont know how you came up with this. thanks for sharing

[maiden wadi]

Not quite. The recipes are not data assets.

The recipes are a struct with two arrays of a second struct. The second struct holds IDs to the assets.

You might be familiar with how people identify items via keys? Like Enums, GameplayTags, FNames, or Integers? Instead of those, I identify an item by the asset it holds.

No point abstracting it out to a key when you can just directly use the asset that specifies the item's defaults and descriptions.

If I declare an interface as an instance editable variable, is there any way to assign to that in the editor before play starts? It looks like I can't do anything with it that way, and I instead have to assign the actor containing the interface and extract the implementation out from it. It's just a bit more brittle that I would have expected.

[versed sun]

not sure what "declare an interface as an instance editable variable" is , but you can Bind things in construction script

[manic vessel]

Im pretty much done here with My Quick Inventory, But when I cycle through the 3 weapons with each press. Im hitting an area where 2 of them are nothing, Can Anyone see an issue here

[maiden wadi]

What exactly are you trying to do? An interface variable is basically the same thing as a hard pointer. It's just referencing an object in a way that it can only access it's interface functions.

[short phoenix]

I was trying to use it to notify something had been activated. I've been trying with events too and have been trying to weigh them all. So all I needed was the function to call when something was activated through the rules of the interface.

[manic vessel]

cycle through the item array one index at a time and when it reached the last is goes back to the first item

[barren kestrel]

Hi guys any idea of how to convert an (automation editor task object refrence/output of a screen shot) into an image

[lofty rapids]

well your not checking if the currentIndex+1 is within a valid range of the size

so ig technically you could check if the currentIndex is valid, it may be at the last one, then when you ++ and try to get it's out of bounds or something just a guess

[versed sun]

Theres always a better way, and probably a better way than this
Save the 1st item and remove it and place at end of array

[manic vessel]

This seems to work thanks .

change to this lol, think it makes more sense ?

[broken gazelle]

You can use modulo node

++
Then modulo the number of items

[lofty rapids]

i would check +1, i think ++ actually changes it which you probably don't want to do if it's not in range

then do the ++ on true

i mean you are setting it back to zero on false

so ig that's fine

[manic vessel]

Yeah I Like how I have a index with no actor so I can select nothing

Think Im done with this, Got the end result I wanted, Thanks EVERYONE now I will add some polish

[broken gazelle]

++ sets the get value? So confusing blueprint wise. I would think they would at least annotate the ingoing pin that it is modified

[maiden wadi]

They kinda do. It's by reference.

[broken gazelle]

What do you mean

[plush swallow]

if i accidently created an infinite loop in the construction script how can i open the blueprint to undo it?

[broken gazelle]

Woah shooting yourself in the leg, just like C++

[lofty rapids]

i was saying it alters the value

but they reset it so it didn't go out of bounds

[maiden wadi]

I mean the left pin on the ++ is a diamond, meaning it's by reference. Usually if something is passed this way there's an intention to edit it.

[broken gazelle]

Ah

[lunar sleet]

If you weren’t too deep into it, delete the bp and remake it. Otherwise source control might be the only option

[gentle urchin]

Cant you disable constructionscript from property matrix?

Maybe not

[lunar sleet]

What’s the property matrix

[gentle urchin]

Erh, the bulk edit option for assets

[lunar sleet]

Oh maybe idk

[gentle urchin]

Right click -> asset actions -> bulk edit via prop matrix

[plush swallow]

nah i found another way

[lunar sleet]

Ok, what was it?

[plush swallow]

tho i still cant believe epic hasnt fixed this

apparently its been since forever and its still present in unreal 5

[gentle urchin]

Not a prio would be my guess

[maiden wadi]

It's not really up to Epic to fix though. Adding in something that would not run the construction script sounds like a nightmare if someone leaves that off on accident on some parent class. If a studio wants to implement that themselves, they're kinda free too, but most people just source control it and eyeroll and revert to the last working class.

That said though, usually if you wait long enough, unless the editor actually crashes, the BP will open.

[plush swallow]

i tried that but it doesnt show any construction script enable/disable option

[plush swallow]

uhh why not? its kinda ridiculous that accidently having a node connect itself crashes the whole thing and makes the project unable to open unless you delete it

and having no way of editing it

[maiden wadi]

What node was it? O.o

[plush swallow]

it was a function to disable shadows on the meshes on my actor... lol

i mean it doesnt matter what node it was

[maiden wadi]

Is it actually crashing, or just hanging for a long time?

[plush swallow]

it was just while building the script i was moving the node around in positions and i accidently forgot to remove one of the exec wires that was connected to a node before it

[maiden wadi]

Could also probably lower the loop limit detector to make it faster if it's just hanging. Wait for the BP to open and disconnect it.

[plush swallow]

hanging for a long time then it crashes

i tried setting loop to 100 and even 0 and no fix

[gentle urchin]

You could create your own Actor class where you'd let yourself disable construction script 8-)

[lunar sleet]

Did you ever say how you fixed it?

[plush swallow]

by causing a compilation error

[gentle urchin]

deleting related asset would be one method then i guess 😛

[lunar sleet]

Oh nice

[plush swallow]

yeah u delete somthing the asset references or uses, you open it, fix it save it then u add those assets back and reload

[slender quest]

anybody ever face this problem? Enhanced input action for my character to aim the gun, sometimes the "Completed" exec doesn't go through, neither does the cancelled, to reset the two bools i have there. Why would it not "complete" even though i have released the button?

I am also not sure of how to replicate the issue, i am currently trying but it seems kind of random when it occurs

[naive falcon]

I'm having some trouble getting a pinch to zoom gesture to work in UE 5.2. I need to make this work for a windows build that will run on an ELO touchscreen monitor. I have multi touch set up on the ELO. In UE I have enabled 'Enable Gesture Recognizer' and created an axis map that is set to the pinch gesture. However in my blueprint, the pinch event only prints 0.

Since I am not building this as a mobile app, I think unreal is recognizing the touch events from the ELO as regular mouse clicks. Anyone know how I can get this working?

[kind estuary]

damn i just lost myself in my mess of a project. i have an ai pawn being spawned, i dont know where is it being spawned from. how can debug this?

how can i see where a pawn is being spawned from?

trying to use the reference viewer

but cant locate it like that

[lofty rapids]

you can search for spawn in the blueprint

idk how you would search through multiple but in a single one you may be able to find spawn

[lunar sleet]

Is it a chorded action/combo?

[lunar sleet]

Either use ctrl+shift+f to begin with or ctrl+f , type word, hit binoculars @kind estuary

[kind estuary]

i tried that. made me realize its not in blueprint, so i found it in the cpp

thanks

[kind estuary]

thanks

[restive breach]

would some one please give me ahand on a blue print? its for stamina drain and gain i did this and it works but you have to spam the w insted of it just looping tell you let go of your move button

[calm gull]

I'm trying to add a static mesh component to an actor runtime in UE5.1.0, but cannot find any functions that could help. Basically looking for something like this image (snapped from this unreal engine forum post [the question they have is irrelevant for me]: https://forums.unrealengine.com/t/how-to-set-static-mesh-in-add-static-mesh-component-with-variable/508155 ) Anyone had similar issues?

[lunar sleet]

You have a do once in there that’s not being reset until stop stamina drain is called

[versed sun]

That is the correct function, are you saying its not showing up for you?

[calm gull]

Yes, exactly, it isn't showing up for me at all

[forum in question is ue4 i think]

[versed sun]

are you in a Blueprint? or a widget? player controller ?

[calm gull]

an actor blueprint

[versed sun]

hmm, should show up...

[calm gull]

YES, THANK YOU will circumvent this way (your question was perfect, i was trying to call it from an actor component of the player controller, THANK YOU!!! )

[versed sun]

ahh, yah , cant do in actor component

or widgets

[calm gull]

thats okay, will add a function and will just call that, THANK YOU AGAIN

[sick fable]

Can someone help me please

[lunar sleet]

don't ask to ask, just ask

[sick fable]

I want the dog to attack every 1 second while chasing

but for some reason it can spam continously

I removed the delay

from the screenshot while trying to fix it let me put it back

@lunar sleet Do you get a lot of satisfaction from helping people lol because you helped me a lot

[lunar sleet]

no, I'm just a masochist 🙂

do you know how to use set timer by event?

[sick fable]

nope

it attacks me then takes a pause but when I stop moving it can spam attack me really hard

like pauses to do the bite animation

Idk about timer by event

[slender quest]

It's not, it's set up like this:

[lunar sleet]

you're saying your completed pin never fires?

[lunar sleet]

if you remove the delay, does it wait for the montage to complete before applying the damage ?

[sick fable]

I think so

[slender quest]

It fires most of the time, but on some occasions it does not fire, but i haven't been able to pinpoint what causes it to not fire. I could be walking around and pressing and releasing aim over and over, and it will work 99% of the time when i release it, but 1% of the time it does not go through

[sick fable]

Im not sure but the animation to attack is only like almost a second

[lunar sleet]

and how do you know it doesn't go through, are you watching it live, printing, breakpoints?

[sick fable]

I want a delay while it chases me till it can do another bite animation

[lunar sleet]

right, but your delay is using the montage duration, not the duration it takes to get to you

and either way if he's right next to you that'll be instant

[sick fable]

well I want when Im on the spot for it not to be able to spam attack me

maybe like 2 second delay

or 1.5

what im doing isn't working

[lunar sleet]

yeah cause delays are often misused

Do this instead: on Success of the Move, Set timer by Event

Create a custom event called Bite (or w/e)
drag from the red square (delegate pin) of the bite event and plug it into the timer's Event pin
Set the Timer's Time to whatever you want it to be, set it to looping.
When you want the dog to stop biting, drag from the timer handle (you can also promote to variable), and use clear and invalidate timer by handle to stop it from biting

[slender quest]

When it does not fire, the char will be stuck in a weird position because the rotation is not turned back on, so then I know it happened, I pause it, and go examine the blueprints and I see that the "IsAiming?" is still set to true, and the "Action Value" coming out of the enhanced input action event is still set to true as well. The only place where "IsAiming?" can be set to false is when it either completes or cancels from here, so my conclusion was that it does not fire

[thick flame]

I had the same issue, following a tutorial. The issue is that the follow player event is called every tick that vision happens, so the animation can still play despite the delay set up. Move it to set canAttack to true on Play

[lunar sleet]

...why not just change the default value to True then?

[thick flame]

that makes more sense lol

im very new to ue, but i had the same issue so i thought id give my solution

[lunar sleet]

well tbh I haven't played with montages enough, so if that lets you control the timing, good enough

[sick fable]

is this what you meant

[lunar sleet]

Put a Print String on the Completed Pin to make 100% sure

[sick fable]

i did nothing with the event so I was wrong lol

[lunar sleet]

Almost. The way you have it, you're clearing the timer after the first loop, so that's not gonna bite anymore

For starters, remove the clear and invalidate node and move the stuff after it down to the Bite.

[sick fable]

how can i fix it

[thick flame]

ive got a similar issue atm, my animation works for both my player and enemy, but the damage is no longer working

[sick fable]

@lunar sleet

[lunar sleet]

yeah, I'm trying to account for preventing it from trying to bite while it's chasing the player around, before it reaches it

if this an #gameplay-ai , BTs with cooldowns might be much better here

[thick flame]

does my method apply to yours?

[sick fable]

It doesn't bite too close to the play it bites when it reaches me

but then spams it

[lunar sleet]

with the current code?

[sick fable]

no

now it doesn't

bite

[lunar sleet]

At all?

[sick fable]

not even once

[lunar sleet]

is the Play Montage node firing (breakpoint)?

[sick fable]

no

[thick flame]

playAnimMontage returns a Value- that value is your animation length. You dont need to set a variable called BiteDelay

[lunar sleet]

why did you remove your boolean

you moved it up and left it there

[sick fable]

oh

[lunar sleet]

yeah, that's also redundant now

[thick flame]

you can then use a multiplier to change the time

[sick fable]

still wont bite

or trigger bite event

[thick flame]

this is what I got from the tutorial. I can send the tutorial if youd like

[lunar sleet]

what's the default value of CanAttack?

[restive breach]

@lunar sleet how would i fix that if you no how

[sick fable]

false

[lunar sleet]

are you following some crappy tutorial too? 🙂

[thick flame]

set it to true

[restive breach]

ya

[lunar sleet]

Your current code is If True run this, if False, fuck it

[restive breach]

im loring blue prints

[sick fable]

oh

Loool

I thought it changes it there to can attack

if it sees the player

[thick flame]

im still confused on why you have the custom event here. Is it all for the timer? cuz you can cut a lot of this out

[sick fable]

still wont bite

[sick fable]

I was just listening to Neo

[thick flame]

oh

well, if you look at the code I posted, you can go right out of the second set can attack into the animMontage

[lunar sleet]

Reset the Do Once when your initial Drain event is completed, not just when you stop draining, because if you don't let go of W Stop draining is never called as far as I can tell.
Or get rid of Do Once altogether.
Also, if you're following a tutorial and it works for them and not for you, watch it again, prly missed a step

[sick fable]

well now it is biting non stop

again

/attacking

[thick flame]

did you do this

[sick fable]

nope

lol

I keep forgeting to add stuff

I removed

[thick flame]

this is where the delay comes in

[sick fable]

Sorry I am tired and new

[thick flame]

i would just use the code i posted. I got it from a tutorial

[lunar sleet]

yeah do what works for K2000 rn, realistically this should prly be done in a behaviour tree, but for now duct tape and glue is fine

[sick fable]

lol

[jagged parrot]

How can I communicate between blueprints easier? I've been trying to get an collision part to relay that it has been hit to a widget "interface" and im struggling a lot xD

[sick fable]

finally fixed

[lunar sleet]

there's a blueprint comms video pinned here that's worth watching. as for a collision "hitting" a widget, idk that you can do that, but maybe ask #umg

[lunar sleet]

is your damage working now?

[thick flame]

no, i havent gotten anywhere lol

[jagged parrot]

I'll give it a Shot! - I've literally just been trying to make a countdown system, with time bonus pickups (Hence the collision - widget situation)

[lunar sleet]

is this the same code you're giving to Kiro?

[thick flame]

i tried to swap code between the player and the dummy instead of finding a tutorial

[sick fable]

mine is

I can show mine

if you want

[lunar sleet]

you usually collide with actors not widgets

[thick flame]

different section of code

[lunar sleet]

show

[wicked fable]

Would anyone know how to fade out a widget after its full (fade out stamina bar when at 100%)

[lunar sleet]

#umg is best for widget related stuff

[thick flame]

i havent connected it yet. my player cant damage the dummy either

[wicked fable]

Oh thanks, i was looking for a ui chat

[lunar sleet]

did you print out the hit actor to make sure it hits the right thing?

[thick flame]

i tried printing on damage and got nothing

ill try somewhere in sword hit manager

[lunar sleet]

that part looks fine

[lunar sleet]

go off the hit actor on break hit result

print the value

Camera trace channel is a weird pick but who am I to judge? 🤷

[thick flame]

trying this

[lunar sleet]

lel

no no

right now your code says: Do A Line Trace, don't care where, then print something, don't care if it hit anything

[thick flame]

ok so it did reat a hit so

oh

its doing that every time no matter what

[lunar sleet]

drag from the hit actor plug into the in String

break hit result happens before the print anyways, it's just not ordered right on your screen

[foggy otter]

is there any way to disable the air control for the flying movement mode in bp? im trying to make a simple dash, and i want the character movement during the dash to not have gravity and not respond to player input (except rotation), until i decide that the dash has ended. is there any semi-legit way to make this work without writing my own movement mode in c++?

[thick flame]

it wont let me go from there

[lunar sleet]

do this:

obv connect the execution path on your end

[thick flame]

like this?

[lunar sleet]

aye

what prints

[thick flame]

nothing

[lunar sleet]

so your line trace is hitting nada

[thick flame]

yeah

[lunar sleet]

try using Visibility channel instead

[thick flame]

ok

[lofty rapids]

a little more complicated than that

[thick flame]

still nothing

[lunar sleet]

you're certain TriggerSword is firing?

[thick flame]

good question

the Trace lines are goiung and the animation is playing, so it should be

[thick flame]

it prints when I hit walls and stuff

[lunar sleet]

so just not your dummy or w/e

[thick flame]

yeah

im so dumb

[lunar sleet]

Test with Trace Complex ticked on. If not, check your collision settings on your target

[thick flame]

of course

[lunar sleet]

🙂

collision be that way

[thick flame]

I turned off camera bc it was acting wierd when the enemy swings

but i should turn on vis

[lunar sleet]

visibility is usually good to stay on yeah

[thick flame]

overlap would be good yeah? to catch the hit but not affect position?

[lunar sleet]

no, because Block = hit, overlap is different

[thick flame]

oh

IT WORKS

LETS GOOOO

what a dumb issue LOL

[lunar sleet]

welcome to game dev

most issues are silly 🙂

[thick flame]

just gotta figure out how to get the enemy to damage the player

[lunar sleet]

similar fashion, apply damage from one end, receive it on the other

[thick flame]

yeah

think i need to rename the event

[cunning vapor]

Does anyone know the best method to making a variable for "is too close"

Ie, is too close to a wall / actor

Trying to make a system where my actor plays an anim montage when too close to an actor/wall/static mesh

Am thinking maybe a collision sphere?

[lunar sleet]

Box might be better

[finite flax]

Help please: On widget drag, how to make an actor material start during drag of widget??! images attached below...

Like in the image below, I'm trying to drag the tower from the widget and place it on the map below, what I want is the second I take the tower from the widget on the left, I want the ACTOR (Circle material shapes) to start/begin, I think I'm close to solve it but need a bit of help, the pictures of the blueprint might help alot!

please tell me the solution with a picture, thank you soo much guys!

imagurLink

[lunar sleet]

Try #umg

[thick flame]

@lunar sleet are you able to answer some more questions?

[lunar sleet]

Sup

[thick flame]

could we call so i can stream? I cant stream in these vcs

[cunning vapor]

Am i using the wrong node? :/

[lunar sleet]

Can’t rly do that rn and I’m not into it tbh. Ask questions here in chat and people will answer, usually people smarter than me

[thick flame]

ok

[lofty rapids]

usually cast have execution, whats up with that not having that ?

[cunning vapor]

was a purecast

[lofty rapids]

Oh i c that, why would you want to do that ?

[lunar sleet]

To detect overlap? Yes. Also don’t use pure casts unless you really know what you’re doing, as engage said

Actor begin overlap is the node to test for overlaps

Well one of them

[lofty rapids]

well you can check if the event is firing, and then check if the cast succeeds

[edgy ginkgo]

is there a way to allow the player to use the foliage tool in game?

[lofty rapids]

i think you need to add the end to the start, and plug that into end

[thick flame]

@onyx galleon

[lofty rapids]

i would also check the return value is true before trying to apply damage

[fluid wraith]

Shouldnt matter if its an interface ¯_(ツ)_/¯

[lofty rapids]

well the line trace

return value

[fluid wraith]

Do you mean the hit bool?

I thought it doesnt matter for interfaces

[thick flame]

line trace is working, bc i iddnt have things connected :)

[fluid wraith]

;'y

[fluid wraith]

All this gives ya is a bool for whether it got a blocking hit or not

[lofty rapids]

right, good thing to check if it's hitting before you try to apply damage is what i was saying

[fluid wraith]

Yeah, but if its hitting nothing, you're not applying damage to anything
