blueprint

[lapis inlet]

Yes but the cast is wrong, as you said

[tawdry surge]

No

[lapis inlet]

Since the method I was using was asking for an object

A gamemode isn't an object, right?

Waaaaaaait

You can link the "cast to gamemode" with "get gamemode"

Wait is that what you said?

[tawdry surge]

Yes

[lapis inlet]

Bruh im so bad

So much thanks!

[tawdry surge]

No problem

[lapis inlet]

And it works, yep!

Oh no, bruh it wojnt

[hollow cape]

you need to cast to your specific gamemode

[lapis inlet]

Wont get the constant G

[tawdry surge]

Gamemode is an object
For casting to work you have to have a thing you to look at a lower class of, so you try to cast to that

[lapis inlet]

Alright I set "cast to gamemode" not maingamebase

my mistake

[tawdry surge]

No

Get gamemode

[lapis inlet]

Yes

[tawdry surge]

Yes

[lapis inlet]

And then calculate velocity from there

[tawdry surge]

Yeah

[lapis inlet]

Got constant G, other components from the equation are "Mass of body at center" and "radius of the orbit"

So cast to the Sun in that case

[tawdry surge]

Yes. Just make sure the white pins are connected

Thats how it knows what to do next

[lapis inlet]

Hmmmmm it seems the game cannot decide if the Sun exists

Even thought there is a sun in the level

[tawdry surge]

Yeah but is your variable pointing to that one?

[lapis inlet]

No...

Can't find "object sun"

[tawdry surge]

So you'll have to get all actors of class, get the 0th element, and use that for your object in the cast

[lapis inlet]

Aaah

[tawdry surge]

Assuming you only have one sun

[lapis inlet]

Yep

Hmmm, I need to extract the mass variable from the sphere component of the Sun

[tawdry surge]

That's fine

[hollow cape]

Bear in mind that GetAllActorsOfClass is a relatively heavy call. Fine for testing, but don't abuse it

[lapis inlet]

Only need it for one thing

Calculating the initial orbital velocity, which should only be applied once at gamestart

[tawdry surge]

If there's only one thing it's fine. But yeah don't use it alot

[tawdry surge]

Yep

[lapis inlet]

Issue is, I cannot get it to call for the sphere of the Sun, which has the mass

[hollow cape]

drag off the output array, get (a copy), element 0, that's the reference to that actor

[lapis inlet]

Aaaaah

[steel shadow]

I think a lot of problems in my game are caused by my ridiculous scale

[hollow cape]

and I would hit some tutorials to get more familiar with methods of getting references, and general gameplay logic

[steel shadow]

Like I have 2 trees that are within 10 metres in my game scale, but are 29k unreal units apart

[lapis inlet]

It works!

Well

the calling sun part

[steel shadow]

I have to give characters speed values of hundreds of thousands

[lapis inlet]

Still need to calculate distance and then put everything through the equation, then apply velocity

[tawdry surge]

Your math looked fine

[upbeat briar]

Anyone know how to interact with transforms within a game play ability or possibly a better way to DROP weapons on the ground in Lyra?
https://forums.unrealengine.com/t/how-do-i-get-player-transform-within-an-ability-specifically-ga-drop-in-lyra/543156

[lapis inlet]

Oh are you kidding me~

[tawdry surge]

@steel shadow huge numbers run the risk of precision errors if you go into the billions. Especially for wp. Ue5 has the doubles datatype in BP to mitigate this but you should still generally to fake large distances with smaller scale

[lapis inlet]

"Cast to MainGameBase" seems to be failing

[tawdry surge]

Is it assigned as the game mode in the level?

Or project settings

[lapis inlet]

Wait

No my bad

Ooooh my dumbass thought that the print wasn't working

But in reality it was

It just wasn't connected

[pine trellis]

What's the console command that brings up the draw calls and all the other info?

I was using stat fps but that only shows fps

I can't remember

[lapis inlet]

Anyways turns out the equation isn't actually useful because it simply tells the velocity of an object, and not the XY&Z velocity, nor is it build for UE4

[tawdry surge]

Math is math

[lapis inlet]

Indeed

Just need to keep experimenting then

Fuck it I'll just add player movement, anyone know how to do a "click to move in x direction by applying force?"

[tawdry surge]

Yeah. Also you made sure that unreals global gravity scale was set to 0 if you're creating your own right?

[lapis inlet]

Yep

[tawdry surge]

Ok

[lapis inlet]

Gravity is set to 0 and it doesn't work regardless because everything is locked on the Z axis

Meaning the game is two-dimensional

[tawdry surge]

So you want x,y, and leave z at 0

[lapis inlet]

nods

[tawdry surge]

You can right click the vector pin on the apply force node and split it

Add you x,y floats and hard code z to 0

[lapis inlet]

I'm having trouble with making the game know just what direction the player mouse is

Then putting a force that pushes the player in that direction

[tawdry surge]

Physics are tricky like that

[vapid comet]

I'm trying to follow along with this vide guide https://youtu.be/05IDz-GUrJA to make a heart based health system. but every time I try to test it i run into this error

i assume it has something to do with how i have the dynamicMatRef set up but i cant figure out whats going on

[tawdry surge]

Does heart image have a dynamic material to get?

[vapid comet]

oh god i hooked up the wrong heart image

[steel shadow]

Well I am not sure I am in the billions but my scale is larger than i'd like. My scenes are about 200k x 200k unreal units across each way. My flying characters move at max speeds of (ball park estimate) 30k unreal units a second. Would this be a source of precision errors maybe? It's a multiplayer game so maybe very hard to do movement prediction? I could downscale x10 see if that helps.

[trim matrix]

how do i make the enemy damage the player when it gets close

[solar bison]

Yooo can I not have inputs in event dispatchers?

Oh I can nvm, I'm dumb

[odd ember]

sounds like why precision errors are happening. what are you making since you need these distances and speeds?

[tawdry surge]

So it's less than 10 seconds to cross your map?

[steel shadow]

a game with flying insects

at max speed, which takes a while to accelerate to

[tawdry surge]

Suppose it should be ok at those numbers but why not just leave the engine scale alone and adjust your personal scaling math when placing things and calculating distances/speeds?

[steel shadow]

its multiplayer i already had a conversation in #multiplayer and the advice was such scales are bad for multiplayer games so I am downscaling

[icy dragon]

Why not have the whole world scaled up?

As in things that are normal sized from a human perspective actually larger than it should to emulate smaller insect perspective

Are there any conflict with this approach on your design docs or even issues during testing?

[neat prairie]

hi,
I'm trying to get the material instance used on my landscape. I had the blueprint for it before but being an idiot I deleted it. does anyone know how to get it?

i can get the material from the landscape but it's a material interface object not a material instance dynamic object

[sonic crest]

I found a workaround for this

that's basically it

created another data table for this

and works

[high ocean]

@brazen pikeThanks, your idea of the mesh itself colliding and things having nothing to do with the material's opacity mask got me to solve the problem - yep, I had a collision bug somewhere else in the procedural generation. Fixed it, and now it works as intended. Thank you! 😄

[neat prairie]

can you cast from material interface to instance?

[high ocean]

@neat prairieget the material's reference which will be of type material interface, use create dynamic material instance, save it's ref and operate your params on that.

@neat prairiehere, for reference:

[neat prairie]

okay. however, the landscape does use a material instance by default, if that is any simpler?

[high ocean]

it's fine

[neat prairie]

but that does look like what i had

[high ocean]

to be completely honest, I don't quite understand myself where this "interface" comes from, I've seen it's a different type of class than material/material instance & since it always worked like that, I've never bothered to clear the fog

[neat prairie]

fair enough. thanks

[high ocean]

hope it helps, np. Wish I knew, maybe someone will see this convo and clear the fog for us 🙂

[trail imp]

I'm going through a tutorial - has the Float + Float node been changed to something else?

[icy dragon]

If you're in UE5, math nodes are universal (and with that comes few setbacks)

[trail imp]

yes, UE5

alright, so it needs a new approach to do the same thing?

put in an add node

[icy dragon]

Not exactly new approach, but just use add node and hook anything into it

[brazen pike]

If you don't mind explaining, what are the setbacks? As someone who hasn't used UE5 but will probably be working with it in a few months time, I'm curious to know

[trail imp]

so like that?

[icy dragon]

The setbacks would be that some math op node with certain variables have additional input that doesn't seem to be present with the universal node (e.g. equals for vector have tolerance value). Not to mention people won't know what var pairings that aren't compatible.

[icy dragon]

Yes.

[brazen pike]

did they remove the old nodes and replace them with the universal or just add the universal as the default one it provides?

[icy dragon]

The former

[brazen pike]

ugh that sucks

Is there another way to do error tolerance for vectors equal

since I abuse that quite a bit in my bps

[remote meteor]

vector should have its own equal node isnt it

[untold fossil]

Small math and blueprint question. How can I get the vector between two vectors. I have two vectors, one is from a laser cannon. Second is from my camera that can look 360 around. I want the laser to fire where the camera is looking BUT only when the camera is within 20 degrees (dot product) of the forward vector of the laser turret. If the camera is outside the 20 degrees I want the laser to fire at the most prefered direction which is:
https://gyazo.com/ca6bf96828daf310819bc4677017bcda

[remote meteor]

rotate around y axis 20 degree from the btm vector?

[late gorge]

ok so im using "SetGamePaused" to pause the game in my UI

and that makes my inputs not work...

any ideas why that might happen?

the input mode is set to GameAndUI

[neat prairie]

this isn't working for me. no errors, but if I try and change a parameter nothing happens

[rose kettle]

Hi! My save load system I made does not seem to be working, any ideas why? I followed with this tutorial https://youtu.be/coPqS4eTphM

[neat prairie]

what's not working about it

[rose kettle]

After I save and restart the game and click load, it just spawns me at the default location and not the saved one

I think it's smth to do with the saving

[late gorge]

well, that's embarassing

it was right there the entire time

https://tenor.com/view/triggered-oh-my-god-super-triggered-oh-my-god-rage-gif-21375197

[high ocean]

are you sure you are actually setting the mesh (or whatever you need) to use the dynamic material that you are actually modifying?

[neat prairie]

hold on i may have solved it

[neat prairie]

try saving to a .txt just so you can verify the saving works. it's probably some obscure reason the stats don't save properly

[neat prairie]

hmmm well it says i have done, in the blueprint, but not in the inspector

[mighty cliff]

trying to lower a players friction, do i would have to run the event as the server or do i run it on the server and owning player?

or does anyone know of a good tutorial for adding network replicated sliding?

[neat prairie]

try #multiplayer

[livid vessel]

Hey! I have a bit more specific question and I hope someone can answer it. I want some sort of shader (or whatever makes sense) that does a hue shift in a radius around an object. Similar to a decal, just 3D. Any ideas how to achieve this effect?

[high ocean]

@neat prairienot sure what you mean by inspector

[neat prairie]

(sorry, unity lingo) like, if i click on the landscape in the editor when playing, and check the Details->Landscape Material

[mighty cliff]

will do banana, thanks

[high ocean]

@neat prairiewait... are we talking landscape material?! How do you ref and operate on a landscape material at all!? We talking ue4 - right?

[neat prairie]

yeah... there's not much of a difference?

you can put a regular material of any kind into a landscape like it was any other static mesh

[high ocean]

yea, no, not really, it's a little different, and afaik, you can't change landscape material at runtime, so making a DMI is pointless, so that's why it isn't working

landscape material has a layering system which makes it different from materials "on any static mesh"

[neat prairie]

fuck i just found out you can import heightmaps from texture with a blueprint

i shouldve been doing that all along

[high ocean]

for landscape? No need for a blueprint, just import a heightmap, make sure it's normalized otherwise you're in for a surprise. There's a guide in the docs about importing heightmaps/use terrasculpt's UE preset.

anyway, i feel all of this is kinda off-topic, not blueprint stuff, more like #level-design

[neat prairie]

but i am trying to change the heightmap on the fly

[high ocean]

ok, look: don't use landscape and you can do whatever you like. If you use landscape, you can't do shit to it at runtime

[neat prairie]

hue shift on what? the screen, or just the adjacent object

[neat prairie]

false (i am doing everything to it at runtime), but nevermind.

[high ocean]

🤷‍♂️ ok then... gl 😆

[dawn topaz]

https://spaceplace.gibsonmartelli.com/2018/04/05/global-variable-in-unreal/
I followed this tutorial exactly and it's giving me this error, what should I do? Do I recreate the variable in this pickup item BP? (That didn't work, as suspected. Still lost!)

[tight schooner]

Try compiling TP_GameInstance BP?

[dawn topaz]

Oh my god, I forgot to hit compile. 🥴

Sometimes it's the simplest things...

[livid vessel]

On the Objects texture in radius

[undone surge]

im trying to make the AI walk towards my direction when i t loses sight of me but i want it to be random. how do i tell it to go in any random direction except for backwards

[livid vessel]

but maybe rendering it on the screen would also be an option

[faint pasture]

Calc delta from cannon to aim, clamp to 20 degrees, add to cannon

So if aim is 45,0,45 and cannon is 15,0,15, delta would be 30,0,30 clamped to 20,0,20, readded to cannon resulting in 35,0,35

do it on rotators though, don't break them (other than maybe the clamping), so it'll behave

You can delta and combine rotators

[trim matrix]

hey guys

Im trying to make AI play an animation when hes close to the player

not too sure why the animation wont play

I state that if the distance between the player and the enemy is less than 5 it will activate the animation

[faint pasture]

You set attack animation to false in both outputs of that branch...

[trim matrix]

oh

I just changed it to true

and still doesnt work

[faint pasture]

You're gonna want to get rid of the NOT in the 2nd transition too

wait nvm

5 distance is dummy short, try 200

Also you want distance from player pawn, not their controller

Not sure if the controller moves with the pawn or not but I wouldn't rely on it

[cyan birch]

Yea, Units are roughly equivalent to a centimeter so 5cm probably isn't even beyond your character's nipple hairs.

[trim matrix]

I think its better if I just say if I collide with player

[faint pasture]

You'll want at least double the capsule radius so 100

Make it work then tune it

right now it doesn't work

[cyan sedge]

Hey, everyone hope your having a good day I want to make this playable but don't know-how is there some steps or tutorials you can recommend, I have imported the animation into UE5 but don't know what to do next.

[trim matrix]

its not really working either with the collision capsule

[faint pasture]

Start with a pawn. Look at the 3rd person template.

[trim matrix]

something wrong here?

[cyan sedge]

is there any tutorials

[faint pasture]

Read my name lol.
You'll want to just open up the 3rd person template starter and look at its animBP

you can probably just swap mesh and animations and parts of it will just work

[cyan sedge]

alr thanks If I need more help I'll dm you.

[faint pasture]

The new mannequin anim bps are much more complex, look at the older one.

[cyan sedge]

k

[trim matrix]

is this the right way to get a variable from my anim bp

?

im getting errors

[trim matrix]

how to replace time with a variable in curves?

[zealous moth]

No. When you cast into something you get a reference to the class. You define the class with the input and use the output as a downstream reference. In your case, you cast and you are not using your reference at all

[zealous moth]

use delta time differences and plot it out on the curve

[trim matrix]

can you link me a website/documentation/ youtube video? I am really struggling to find a solution and don't understand how to use delta time to do the job

[zealous moth]

uh lemme build it

sec

[trim matrix]

Hey folks said I would post a video on this one. Trying to make my Ball move left to right only (Like a side scroller, just testing out stuff to learn). For some reason the camera is rotating with the ball but I believe I have all the settings correct. I uploaded the video, could someone have a quick look: https://youtu.be/og87PxJw1gA

[zealous moth]

Curve ref is a curve float type variable

[zealous moth]

Do you want it to move through physics or through imagination?

the problem is that your spring arm is parented to the ball. If you move it physically, you are moving the root point so the camera rotates

either unparent it

or separate it entirely and make it an independent actor that follows the ball

[trim matrix]

So my bad, i think you got it wrong, I meant something like Speed on X axis and Height of Actor on Y axis

[zealous moth]

gonna need more context than than :/

what is it you are trying to do?

[trim matrix]

so I need a curve with X axis as a variable and Y axis as a variable and none of them are time

not a variable but a curve like values

[zealous moth]

right click in the explorer, create a new file, misc and make it a curve

[trim matrix]

so this is what I want visualized

by default the x axis is time

I wanna change that

@zealous moth

[faint pasture]

@trim matrixTime is just the name for X axis in a curve

input time, get value

just put your keys in there and use it

[trim matrix]

OH you are a lifesaver thanks to both of you for helping

[zealous moth]

at the end of the day it is still a float to float matrix

[obtuse current]

Can I change an actor's replication role at runtime? I want to temporarily make my local player character a simulated proxy so I can move it only on the server and have it appear to animate and so forth on client, without expecting client input

[barren sonnet]

Anyone know why a construction script would only work correctly when in game only if the the actor is placed in the Persistent level ?

[late shuttle]

I've found some construction bugs occur when multiple things are loaded at the same time. I've found loading the level, the game mode, the player character, the player controller and pulling variables from different things sometimes breaks at first tick because I didn't understand the order in which everything loads.

I found the solution was to have GameMode construct as much as possible within reason then have other things pull references after GameMode had constructed. I'm not an expert on the topic but this may be something to look into.

[barren sonnet]

hmmm yeah that might be it and would make most sense. Thanks!

[calm cargo]

Is there any way to unbind an event from all its binds, without needing the broadcaster reference?

[hollow gorge]

is it possible to remain in control over character movement when keyboard focus is set to a widget's button? i.e.: The keyboard input should be able to sent to both (movement + button) simultaneously.
Edit: More specifically, is there a prebuilt functionality for that or do I need to implement a workaround?

[zealous moth]

@hollow gorge is it possible? Yes.
Built in? No.
You will need to tell your pawn not to use certain inputs while the ui takes them.

[drifting peak]

anyone know a method to procedurally generate a walkable mesh(quad) to projectile hit location?

[gentle urchin]

Listen for input, non consuming?

[zealous moth]

I was thinking a simple boolean

[gentle urchin]

I guess that could work aswell

I would expect setting up input listeners would do the same trick, but im not sure :p

[cobalt gulch]

Hi

I have a timeline which increases a players yaw for weapon recoil

How could I make it so when a player equips a vertical grip, it halfs the recoil

[long whale]

does gamemode have built in parameter for number of player connected?

should this work?

[faint pasture]

Depends on how you set up your system but somewhere in it there'll be a multiply by 0.5

[faint pasture]

Size of playerstates array on gamestate

[cobalt gulch]

When I play a reload anim it takes longer than the delay to reload

Can I speed/slow the anim with nodes?

[long whale]

thanks

[dusk nymph]

Hello I'm using a server to save my player data but to save the player's inventory what to do I can't save the actor directly should I save its name and get it by its name somehow or there is another better way?

[hollow gorge]

is there an event that goes off for when pressing enter key on a focused widget button? If so, what's it called?

[cobalt gulch]

How can I check if a button is down?

I want to make it so if the player is still holding down the rmb then they will keep aiming after reloading

[silk cosmos]

just set a boolean while aiming

[cobalt gulch]

But it doesnt keep aiming after the reload

if the rmb is down

[silk cosmos]

?
input action on pressed -> boolean is aiming = true
input action on release -> boolean is aiming = false
now you know when youre aiming

[cobalt gulch]

I know

but it doesnt keep it after the reload

[silk cosmos]

unless youre resetting it or releasing the button in any when then that boolean would always be true while holding down input action

[long whale]

Hi, I want to make a start menu with some rendered scene. Need to set up a camera, can I do that without a default pawn class?

[torpid mulch]

Hi guys, is the default character modifiable? I wanted the character rotation to change with the mouse (character always looking to camera direction) but on the blueprint I can't edit the functions. If I want to modify the character entirely such as the Jump function, should I create a common pawn instead of a character?

[silk cosmos]

You can still use the character class, you'll just have to make your own jump function, if you want to modify it. You can also easily make the character look toward mouse direction

[torpid mulch]

So I can ignore the already made functions and create my own, right?

[silk cosmos]

Ye you can

[torpid mulch]

Yeah but what confuses me is that I can't see what is inside of the pre-made functions, I don't know if the default movement messes with rotation already hm

[silk cosmos]

you can look at the variables inside your movement component and edit those to your liking.

[torpid mulch]

Oh so this is the component with all the movement and character information?

[silk cosmos]

if you tried to use a pawn class youd have to make your own movement system which would be quite complicated and kinda pointless unless you need very specific movement

yes

that is what basically handles your movement

[torpid mulch]

I see now, I thought that was something hidden, now I can understand it better xD

Oh it even has the rotation on camera dir. by default :0

[silk cosmos]

yeah make sure orient rotation to movement is off in the character movement component while that is on or theyll fight eachother

[faint pasture]

I say this almost every day, we need a Casting 101 sticky because it's every damn day you see someone new thinking cast is a "get" or something.

[tight schooner]

You cast your line into the river of objects and when you feel that nibble you reel it in

Damn, another accessed none

[tawdry surge]

I doubt they'd read it anyway

[zealous moth]

@tawdry surge
Come to blueprints
See a how to cast question
Go back to cozy graphics

Nobody bothers us

[trim matrix]

does anybody why the value is not going up

it just adds once and it stays like that forever

its suppose to add +1 to the variable Number of attacks every 3 secondes

[sudden nimbus]

i think you intend to have "Number of Attacks" as one of the two inputs to +, and the other being the value 1, which you could just hardcode here unless you need the amount to add to vary at runtime

if you've already tried that, if Number of Attacks is a "Local Variable" here then you are starting with a fresh zero each time the function is called

but i cant see all the context

[trim matrix]

Basically trying to set the timer at 2.8 for the first attack

then back to 2.4 for the rest of the attacks

@sudden nimbus

[sudden nimbus]

do you mean to use your variable for that 2.8? you've got it set to be always 2.8

[brazen merlin]

For starters, adding those two variables will work but only the one time. You want to add to the number of attacks and the set it so that the next time it increments up.

The branch node doesnt do anything currently, it is always true so its the same as if it wasnt there.

[sudden nimbus]

a useful pattern for turning it on and off for debugging, but yeah otherwise is doing nothing

[jaunty jolt]

How do i insert a Niagara Emitter in my blueprint actor? I can only inset Niagara System.

[brazen pike]

Why not convert it to a system with only the emitter in it

[trim matrix]

fuck

so what do i do

[sudden nimbus]

panic

[trim matrix]

😭

[jaunty jolt]

So right clicked it and then Create Niagara System. It worked it created NE_Smoke_System. But when i add it to my blueprint, instead of smoke its just some squares?

[sudden nimbus]

spitballing here-- assuming whatever "Number 1" is is -0.4, what about this? bear in mind it will just reduce -0.4 after each attack i assume (seriously not enough information to know what any of this is). If you want it to be 2.8 the first time and 2.4 for all other times its run, then just make a variable thats 2.8, and call "Set WhateverVariable" to 2.4 after the attack, and then just use "WhateverVariable" for the Time on the timer you are making.

[sudden nimbus]

when playing the game, its gray squares instead of the particle you expect? sounds like shader compiling

(waits for shaders to compile for the "ah ha" moment)

[brazen merlin]

You have: var1 + var2 = var3, where var3 is being set... var1 and var2 are static in this case, they never change

You want: var1 + var2 = var2, so that you are adding to the amount each time it goes through

[sudden nimbus]

^^ yep

[woeful timber]

Any way to search all blueprints for a particular key word? (Similar to how I would 'find in files' in C++)

[trim matrix]

ohhhhhh

it works

thanks man

so over here I can put a if branch after the attack boolean

and say that if number of attacks is higher than 1

set the time to 2.4

is this the right way to do it?

[brazen merlin]

I dont really understand what you have... but what you are asking makes sense

[trim matrix]

basically when it starts attacking it doesn't have the cooldown animation

so the damage reduction comes in faster

after the second attack its a slower animation before the AI hits the player

[brazen pike]

Theres a binoculars button on the search window. That will search all blueprints

If that's what you mean

[trim matrix]

it doesnt work

[brazen pike]

You'd want to have a select float node

[trim matrix]

doesnt work

[brazen pike]

What do you mean

[trim matrix]

I want the time to be 3.2 sec after the second attack

[jaunty jolt]

I need to know when my character starts moving and when stops moving? Like Event Begin Moving? Something like that?
So that i can trigger some effects like dust.

[brazen pike]

What about movement inputs? Like pressing W to move forward?

[jaunty jolt]

@brazen pike Im controlling many groups of characters, rabbits, with ai move to. will that work in this situation too?

i thought about that. but its hard. because im sending groups of rabbits to different places by clicking. that means i would need to check when they arrive to stop the dust

[trim matrix]

i dont understand why my code is not working

[brazen pike]

Surely this would save you some branches

[brazen pike]

Many people do footstep audio using notifies in the walking animation. You could do something like that.

[jaunty jolt]

I see. The alternative is to put a check - Is Walking? In the Event tick. That is to be avoided right?

[brazen pike]

You could do that, but most people would advise against it

[trim matrix]

wheres your if branch

[brazen pike]

You don't really need it. The select does a similar thing but with a variable instead of execution line

[trim matrix]

im kinda confused by the second select float node @brazen pike

[foggy escarp]

Math is confusing

[thin panther]

Only way to get better is to keep trying!

[brazen pike]

Here is another way of doing it that might be a bit less confusing:

it is getting the number of attacks and checking what time it should output based on them. If there has been zero attacks, then it will choose time 2.8, and if there has been 1 attack it will choose 3.0 and the same with 2 attacks choosing 3.2.

I've clamped it to 0-2 because you only mentioned three (and with this setup if number of attacks exceeds 2 then it will output 0)

[trim matrix]

can I make it stay at 3.0 forever after the 2nd attack

[brazen pike]

yeah, you'd just make the max be 1 and remove 3.2 as an option

but if you only want 2.8 and 3.0 then make it a boolean

[trim matrix]

so if its not true it pick B ?

[brazen pike]

That will be 2.4 for attack #1 and attack #2 but 2.8 for attack #3, is that what you want?

[brazen pike]

yes

[trim matrix]

Oh

then I think thats all I need

[brazen pike]

Where you do change the number of attacks

[trim matrix]

when the collision stops between the AI and the player ill just set the number of attacks back to 0

over here

[brazen pike]

Okay. And how does it know how many attacks it has done

[trim matrix]

I tried both the clamp and select float method and none of them seem to work

My mental health bar just goes down every 1.4 seconds

[trim matrix]

oh

well that wont work in my favor

I need to find a new solution

[minor wolf]

Happens to all of us, don't sweat it

[trim matrix]

no pun intended

[brazen pike]

Can you show the entire blueprint? Because only seeing individual parts makes it hard to help

[minor wolf]

Isn't there a website run my epic where you can paste in your blueprint and it will generate an interactive graph so you can share it around?

[brazen pike]

https://blueprintue.com/

[trim matrix]

since my game is in a nightmare the character cannot die

so instead we decided to make a mental health bar

[brazen pike]

Instead of it going down every 1.4 seconds, what do you want?

[trim matrix]

https://blueprintue.com/blueprint/4ijcuvji/

How do i scale noise to be used on a procedural mesh? i made a procedural mesh grid and added noise and used the noise for the Z value to get bumps, but the bumps are too small for the polygons and causes a lot of ugly jaggies
I want the bumps to be applied to a larger number of polygons per section so it has larger bumps/dips that arent jagged and ugly

https://blueprintue.com/blueprint/xwwz50m_/

[trim matrix]

well it is in sync with the actual attack animation

ugly jaggies

lemme show you an example

@brazen pike notice how its not in sync. First one is in sync, after that its not

[tardy seal]

Super beginner question here. I am trying to interpolate between two rotations but when I use any of the rotation interpolation nodes, it only rotates my actor a small amount instantly. I assume the answer is obvious but I can't figure it out. Also is this the best discord server for Unreal Engine help?

[brazen pike]

if you debug that when its running, does it all work as you intend? (I mean as in, does the set actor rotation actually get fired)

[trim matrix]

this is what I did last year

[brazen pike]

Yeah, so you probably want to do this in an entirely different way. You want to have mental health attack be fired off only when there is no animation already playing

[trim matrix]

not sure if it will help

[brazen pike]

or do you want to cancel the animation to start a new one?

[tardy seal]

Oh wow I will try this out. Thank you!

[tardy seal]

Yes it does but only for one frame. Having it interpolate faster means it turns more for the single frame it fires.

[trim matrix]

as soon as you see the hands touching the player I want the mental health bar to go down

[brazen pike]

maybe try putting a break point on set actor rotation. If it only fires once for a single frame, then if you continue after the first time it pauses then it should show you if the branch is stopping it

[trim matrix]

so basically as soon as the boolean is true and the timer on the set function by name is over it will decrease the health

because im assuming that's when the actual function will start

[brazen pike]

If the branch is what is causing issues in your BP, then removing it will solve things. I'm not sure why there is a branch there at all, I guess to try and save a little memory or something?

[tardy seal]

The branch is not causing it

[tardy seal]

I almost perfectly copied an example for what I am doing online which is why there is a branch there, and also why I am so confused it isn't working

I also should mention that if I plug the target rotation straight into the set actor rotation it works fine. The interpolation is breaking it for some reason.

[jaunty jolt]

I have this smoke particle effect. When i activate it in the blueprint, it starts emitting a lot of smoke right away. That looks very unnatural. How can i make it fade in. Like emitting little smoke at first? And then slowly emit all?

[brazen pike]

Ok and if you remove the branch and set the interp speed to 1? Does it rotate there over 1 second?

[trim matrix]

lol

now its broken

[tardy seal]

Nope. It just turns a small amount instantly.

I can send a video of it happening. I feel like I've tried almost everything :/

I probably haven't tried a lot but I've tried everything I know how to do as a beginner lol

[trim matrix]

How do I increase the space between vertices? for this procedural mesh grid

[brazen pike]

with the inputs, are you trying to rotate by 90 degrees with each press?

[tardy seal]

Yes

The goal is to just turn the camera 90 degrees if I press one key, and -90 degrees if I press the other key

[brazen pike]

Try doing this instead:

[true valve]

How would you distribute some code onto multiple ticks? Are you talking about using creating custom events?

[tardy seal]

That works fine but the set up I had before changed the rotation value just fine as well. It just breaks when it tries to interpolate between the actor rotation and the desired rotation.

I think I found the issue. For some reason getting the actor rotation doesn't work at all and just gives the starting rotation.

[brazen pike]

Oh you might need to get world rotation

[tardy seal]

ah

what does that mean

[obtuse herald]

That message was literally from a year ago

Depends on what you want to distribute onto multiple ticks

[brazen pike]

There's two types of rotation, Relative and World. World rotation is the rotation it has in the level and relative is what it has in the BP. You might be setting the world rotation but getting the relative. Not too sure. try setting world rotation of the component you want to rotate and then getting the world rotation of the same component

[tardy seal]

That worked! I don't understand it but its working perfectly now. Thank you so much for your help!

[true valve]

Trying to figure how can I have multiple ticks by using FActorTickFunction and FComponentTickFunction.

[obtuse herald]

Oh, yeah I guess that's something different. Have a look on sequence nodes and custom events

[true valve]

But sequence executes one after another. They don't execute the code on multiple frames. Same for custom event. Right?

[obtuse herald]

Tick does fire every frame

are you looking for delay nodes?

[icy dragon]

Or maybe timers

Though I guess multithreading to task thread is the only way to have the tick function not disrupting the main game thread

[true valve]

Trying to do something which was done in this. https://www.youtube.com/watch?v=CBP5bpwkO54

[tardy seal]

What would be the easiest way to move an actor based on it's forward vector using the set actor location node?

[drifting peak]

move component to

or if you want a smooth transition, use a timeline, set world location of the actor you want to move and lerp it from the timeline

@tardy seal

a is the beginning position, b is final position you want it to be at

[tardy seal]

Ah thank you! What I'm trying to figure out is much simpler lol. I just am trying to get position b

[brazen pike]

Are there only two locations you'd need to go to? If there are more (like a character walking around a house) then this isn't a good approach. But if you just want to move a door from the closed position to the open position then a timeline is the way to go

[tardy seal]

When I press W, I want my camera to move forward a specific amount

wait I may have figured it out

[brazen pike]

if your camera is part of a pawn, then you can use the node "add movement input"

and define the direction and scale there

a timeline wouldn't be a good idea with character movement

[tardy seal]

I just want the camera to move a set amount forward without the key being held down when I press W. Would add movement input work for that?

[brazen pike]

A timeline might be a good idea. It just can be unecessarily complicated to change the start/end points when you use a timeline

But if you only ever have 2 locations, then go with a timeline as blake suggested

[tardy seal]

There aren't only two locations unfortunately

idealy I would be able to move anywhere in increments

If you know the game Inscryption, I am trying to make a similar movement system to that

[foggy escarp]

Personally I prefer interping with timers/tick

[brazen pike]

That's what I was thinking here

[tardy seal]

Ok but all I need to know is how to get a location a set amount in front of my actor lol

I have absolutely no idea what i am doing

[brazen pike]

So you can do the same thing you did earlier with the rotation interps. You set a target location you want to get to, and then feed in the current location in world space. You do the same thing but with vectors

[tardy seal]

yes but what Im saying is I have no idea how to get the target location

like

[foggy escarp]

I recomend for doing things like this and have no clue to use debug spheres to mark where u (think a vector or location should go. That way there's less guesswork during testing

[tardy seal]

I have no idea how to even do that

Im sorry I am so clueless

[foggy escarp]

Gotta get after that good dopamine.
Use debug spheres to figure out what vector things do.

[brazen pike]

Do you mean like in this view?

[tardy seal]

No, when the player stands up from the table, pressing W moves you forward like 5 feet, and pressing a or d turns you 90 degrees in either direction

Like moving on a grid

[tame owl]

Can't find good info about this by googling, so I thought I would ask here. Does anyone know of any way of implementing a similar sort of "crime scene investigation/scanning" mechanic as scene in these videos in Unreal Engine? I have a good idea of what the mechanics should be, but I don't even know where to begin to approach something like this. I can assume that the "scanning" aspect could probably be done using a stencil layer or something but beyond that I have no idea.

It would actually help a lot if a more experienced programmer could DM me about this.

https://youtu.be/zk90yuUPlhA

https://youtu.be/YYoE8p4aQh4

[tardy seal]

Wait I just figured it out

I made a vector, multiplied it by the forward vector, then added it to the actors location

[brazen pike]

Yeah so that will get you the vector in front of you by a certain amount. You'd probably want to check if you can move there first, otherwise you might have a room of 4.2 metres width where the player can move 1 metre at a time. If you are 4 metres into the room you'd move forward and sudenly be at 4.2, meaning if you go backwards you're now 0.2 metres offset from the position you actually want to be

So setting specific points where the game knows you have to move to might be a good idea, because it will see there is no point ahead of you to move to, and if you are offset at any time the game will adjust the length of your movement and you'll be fine again

[deep elbow]

can you no longer print to screen furing construction time? is it reserved to runtime only? i swear i used to be able to print when not playing

[tardy seal]

Good idea! My last question is that when I rotate or move it seems to be offset by just a few decimal points. I assume I could just round to the closest whole number but it would be nice if I didn’t have to

[brazen pike]

Yeah that's pretty common, if rounding works go for it

[tardy seal]

Ok thanks!

[brazen pike]

Well there are a ton of different ways to do this. I assume what you are confused about is the mechanics of being able to inspect things only when in investigation mode. That can be done in a lot of ways. The firs thought that came to mind is to have the items always active but interaction is prevented if the player trying to interact is not in investigation mode. That way you can avoid things like getting all actors of class Interactable or maybe a spheretrace around the player activating all interactable items. The scanning effect would be a post-process material that I'm sure with some time you could replicate

Hello there I wanted to tst try each loop for array. It worked well showing me the deduction of 5 from each vari of floats ( values follows: 10, 20 and 30, hence results are 5,15 and 25).Now I wanted to have a delay between these deductions but I am only getting the third result. Do the delay fun dont work with each loop??

[undone surge]

what is the diff between the 2 blue things. one is for the controller bp and the other for the spawned actor pawn?

which one should i use

[brazen pike]

It depends what you're using them for

[undone surge]

if i just want my ai to mvoe around

[brazen pike]

No a delay isn't going to work with a for each loop. You can write your own loop which is delayed by a set amount. I'm sure you can find one online

[opaque acorn]

why it wont work?

[brazen pike]

Again, it depends how you do that. If you are setting a BB value then you'd want the controller. If you're doing something like "set actor location" then the pawn is what you want.

[undone surge]

i see

im using black board

so i guess ill use controller then

[cyan bone]

I copied the standard character. To make my spaceship character.
So it has movement already done.
But now i need it to tremble and shake when it walks or turns. But i have no skeletal mesh in it (because i deleted it),
So what should i do?

[solar bison]

Will Array.Remove() error out if the element isn't present in array?

[lime fulcrum]

Hey guys! How do I remove a pin from the SELECT node? I added one by accident

I mean this node

oh my. It only show up when you right click on the right side of it :
I was going crazy for 10 minutes

[foggy escarp]

https://blueprintue.com/blueprint/f-_8dg59/
Here's a for each loop with delay macro.

[paper gate]

Right click on pin and remove pin

[gentle urchin]

Doesnt it return a bool?

For success/failed

[lime fulcrum]

@paper gate It didn't show up on the Pin but on the right side of it. In the empty area. Probably some DPI scaling issue I guess

😅

[solar bison]

ok good. So basically failed means nothing happens or gets mutated right

[paper gate]

When i click anything in marketplace it open web

[undone surge]

is there a way i can destroy my ai actor and then a little while later make the body dissappear? my ai keeps shooting it cuz it hasnt been destroyed because of the dying animation delay

[brazen pike]

Just check that the target is alive before each shot

[paper gate]

Set a true bool for shooting
When ai killed just make bool false and start animation

[undone surge]

yea but technically its alive untill its destroyed

[brazen pike]

Then.... make it not do that

[undone surge]

hmmm

but after its dead it plays and then animation happens and then its destroyed

[brazen pike]

If it knows when to play the animation, then it knows it's dead. So why can't other AI tell that it's dead?

[undone surge]

tahts what im trying to figure out i have to go over my conditons again

[brazen pike]

When it starts the animation, set a boolean of "IsDead" to true. Then have the AI access that boolean whenever it fires to make sure it isn't shooting a dead target

[undone surge]

thats execatly what i did

but it still shoots when the animation is playing

ill see what the prob is

[pale anchor]

Quick question if my attempt is dumb: I'm building a adventure (Point'n'Click-Style) Game and want to use Text/Audio while interact with items.
like f.e. Use Item A -> Play first Audio for Item A; Use Item A again -> Play second Audio Item; Use Item A AGAIN -> Play third Audio ; etc.

Now for the base... i would build a Structure for a DataTable where I put everything in what I need (Enum for Item; Audio 1,Text 1, Audio 2, Text 2, etc etc.
And i'm gonna call that either over a BP in a higher hierachy (maybe GM or GameState).

Is there a smarter way to store the item related things? I'm using a Item DataTable for my Objects in the World where i basically define via Name what type of item you're.

[icy dragon]

You could make the interactable BP having its own struct array, and get index by the interact count.

[brazen pike]

Using a datatable is probably fine, but personally I wouldnt go for it since you need to add it into the datatable each time rather than just duplicating an object, slightly changing the name and boom new item

[pale anchor]

Ye I thought that as well... I build a BP "WorldItem" where I can define via Name what kind of Mesh, Behaviour and so the Item is... As I destroy those objects via Pickup I'm afraid I would run into issues

[pale anchor]

Ye... thinking about to reverse the idea currently... hm...

But other than that the datatable + struct idea for the stuff should be good to go? I only have maybe 30-50 Items per lvl

[brazen pike]

30-50 unique items? That's quite a lot you may not want to use a datatable for that

[brazen pike]

Also why would anything break when you pickup items?

[pale anchor]

Currently I destroy the Actor put the Struc Item into a Inventory Array and call the object new from that (for examine; useage).

And wouldn't I loose the current state of that BP when I destroy the world instance.. like the Int for the audio count?

[pale anchor]

Any other ideas?

[brazen pike]

Do you mean that an audio plays the first time a type of item is picked up, then later on when a different item of the same type is picked up a different audio plays?

[pale anchor]

Nah... more like f.e. a safe in a room that a player can "use"
Player use it first time: Audio1 (hm.. a safe.. locked..)
Player use it 2nd time: Audio 2 (still locked...)
Player use it 3rd time: Audio 3 (ye that doesn't help to open it)

So these Audio Cues and lines are unique to that item.

[brazen pike]

And in this instance you AREN'T destroying it?

[pale anchor]

That case wouldn't be an issue.

But wouldn't be it worse to have 30-50 unique BPs in the content folder? I guess not? Sry english isn't my first lang... that makes it hard to explain.. i gonna play around and will see how i End.

thanks for the input

[drifting peak]

" attempting to create a joint between objects that are both static" does anyone know what this log means?

[brazen pike]

are you trying to use a physics constraint

[brazen pike]

I guess, if it works: use it. In my experience there isn't any specific problems with doing it in any one way, just that it can be a little annoying and hard to manage. You should do whatever makes the most sense to you.

[undone surge]

does the AI perception debugger show all actor sight and hearing circles?

[drifting peak]

@brazen pike yeah it was accidently left there a while back thanks!

[brittle garnet]

Is there a way to set the Category for a custom, editor callable even I've created in a blueprint? Right now, it shows up in the Default category in the editor. I would like it to be in the Spawning category.

[gentle urchin]

Wouldnt this just play a singular cue with 3 random options ? Picking a random one each time

Can reference dialogue files, abusing the built in subtitle system aswell

[pale anchor]

But Random wouldn't work...

For some objects.. sure.. but not for the majority as there are unique lines for the items.. take things like Pictures on a wall...

Currently I'm building like this:

[gentle urchin]

Random would work for your scenario as I see it

And if not random, surely there exists some sequenced node aswell (wild guess)

I believe the random is also non-repeating

[pale anchor]

Ye thanks for the input.. but random not gonna work for my case

[gentle urchin]

Switch* not sequence

Requires external int input so perhaps not as helpfull

Hard limited to 5 audio/texts

Not a very flexible setup compared to atleast an array

But then again even more work to set up and keep track of in a DB

[pale anchor]

Five should be fine for the scope of the project.

[undone surge]

im trying to get the spawned AI reference here in this cast . what would go into the object pin ?

im casting to controller

[pale anchor]

a reference to the controller

like a defined variable

[undone surge]

can i do get owner ?

[gentle urchin]

If the owner is your ai controller, sure

[undone surge]

the cast always fails

[gentle urchin]

So its not :)

[undone surge]

hmmm

[gentle urchin]

You can print its display name if you're unsure

Get owner()-> get displayname()-> print string

[undone surge]

it prints nothing

hmmm

it doesnt have name /

?

[gentle urchin]

It doesnt have an owner it sounds like

[undone surge]

wait like ai controller is the top most class right in the hiearchy

like in this case

so like i want to get access to the variables in this ai controller class

wat should i be doing

[dusky topaz]

Somewhat insignificant question, but still something I've been thinking about for a while, I assume if I get the game mode, cast it and save it as a variable in one blueprint, it would be better for me to pass that reference to any other references through that blueprint instead of getting the game mode and casting it in each blueprint individually, right?

[tawdry surge]

If you already have it and can easily pass it then go for it, but the gamemode is always loaded so casting to it doesn't really cost much

[dusky topaz]

Hmm, fair enough, so basically: Don't jump through hoops just to get a reference to the game mode to another blueprint?

[remote meteor]

dependency is probably the difference here

[tawdry surge]

Casting to one thing, especially something Iike the gamemode that is always loaded, is better than doing a bunch of work just to avoid casting

[brazen pike]

I think the problem is that if you cast in one spot then have that passed through to everything else, then you end up wirh the issue of having unecessary references all throughout your game

[trim matrix]

i have a spaceship that eventually the player will be able to move, do i use Actor or Pawn for the spaceship?

[tawdry surge]

Pawn

@brazen pike It's always loaded anyway so that wouldn't matter.
Only time that would come into play is if you're passing through intermediary BP's

[trim matrix]

thank you

[modest kestrel]

This is my blueprint for dashing, how can I only dash when I am moving and not when I am standing still.

[earnest tangle]

Check your character's velocity vector's length

[cyan sedge]

why is there no texture here when I added a texture in blender

[modest kestrel]

sorry I am new, how to do that?

[earnest tangle]

Get Velocity -> Get Length -> Greater than

[tawdry surge]

@cyan sedge blender shaders don't transfer

[earnest tangle]

Usually you can find relevant nodes easily by just trying to add a new node and typing in some words :)

[cyan sedge]

so what do I do

[marble warren]

check your material editor and connects texture to parameter

[tawdry surge]

Any assigned material slots will still be there and any texture images will still be imported. However anything you did with the shader node graph in blender will have to be re-done

[modest kestrel]

not able to attach them

[earnest tangle]

If this is in your character BP, you don't need to

The character itself has a velocity, which the node should give you as is

(note the target pin says "Self")

[modest kestrel]

so in firstpersoncamera component I should have velocity?

[cyan sedge]

tutorials?

[tight pollen]

How can I check the local rotation of the AI, which direction is it pointing in relation to the player, AI is it turned backwards or sideways etc.?

I have no idea :/

I want to know more about which side he got the shot from

[tawdry surge]

@cyan sedge Ben Cloward on YouTube has a couple great material series

@tight pollen dot product

[cyan sedge]

does he have a video about the question I am asking

[tawdry surge]

Haha.. be funny if he didn't

[cyan sedge]

hm can you send me a link

[tawdry surge]

Idk what you do and don't know about ue materials. Guessing you're totally new to them and should pry start at the beginning

[cyan sedge]

ight

[tight pollen]

I still have no idea how to do it with this

[cyan bone]

What is more expensive, animating a character, or moving it using vinterp?

[tight pollen]

vinterp

i think

[cyan bone]

but why? isnt it basically the same?

[gentle urchin]

Animating is multuple vinterps ?

Per bone :p

Vs just an actor vinterp

[cyan bone]

So vinterp is cheaper?

[gentle urchin]

Vinterp is dirt cheap

[tawdry surge]

Get the forward vectors for the enemy and the projectile. Do a dot product of the two vectors and it will return a value between 1, -1. One if they are pointing the same way, negative one for opposite, and 0 for perpendicular @tight pollen

[cyan bone]

im using so much vinterp instead of animating the characters. so thats why i was worried

[gentle urchin]

Im at 2k vinterps per tick, no biggie

[tight pollen]

seems to work the way I would like it to, but in this case, how do check if the AI ​​gets hit from the side as well?

[mental trellis]

If it's from the side, the value would be between -0.5 and 0.5 pretty much

[tight pollen]

i checked wrong

all is ok 🙂

thanks for help

[woeful pelican]

I want to be able to detect when the player is exposed to the void. Any ideas?

I have a macgyvered radial line trace that triggers on movement but I don't think it's precise enough or performance light.

[earnest tangle]

"exposed to the void", as in leaving the box there or?

[boreal mesa]

do you think i'm abusing collapsed nodes?

[earnest tangle]

I personally never collapse nodes because I find it easier to follow the logic if it's all visible at once but if you find that helpful then ¯_(ツ)_/¯

[mental trellis]

If you're gonna collapse nodes like that, I'd probably just use a function.

[boreal mesa]

i see, thanks, probably that i should reserve collapsed nodes for more... "special" stuff

[tight pollen]

ok, however, these values ​​are the same. when you shoot AI's right side and AI's left side, it's the same, between 0.5 / -0.5
How can I check if it is right or left side

[woeful pelican]

When the pawn is not completely surrounded by objects

meshes, skyboxes, geometry

[mental trellis]

Assuming a horizontal plane, if your cross instead of dot the vectors, then the resultant z value will tell you which side

[earnest tangle]

@woeful pelican Is this something that can change as result of player actions or is it always based on just location in level?

[mental trellis]

<0 for one side, >0 for the other

[woeful pelican]

You are suggesting that I create "playable volumes" to track the player with, correct? I could do that.

I'd just need to figure out how to make the volume automatically size tightly to the meshes..

For reference, this is what I was doing before.

On every movement frame.

[crude isle]

What do I use instead of Client Play Camera Shake

I'm watching an outdated tutorial so it doesn't exist anymore but I need to use it lol

[tight pollen]

not quite, when I shoot e.g. in the right side and e.g. more towards the front of the character, I have positive values ​​and when I shoot closer to the back but still to the right side, I have negative values

[mental trellis]

Well that's how it should work. 😦

If the 2 vectors are parallel, it should be zero.

[crude isle]

yo anyone tryna answer my question

[mental trellis]

What you could do is inverse transform the incoming vector by the shot character's transform and just check the Y value (<0 for left, >0 for right)

Or <0 for right. Something like that.

Or unrotate if you just have the rotator.

You probably want to do that, as you don't want to involve the shot character's position.

[dapper iron]

Is there a way to consume an input event retroactively?

Say I have an input event hooked up to interact in one of my blueprints, and it has the consume event unchecked; As a result of the interaction I change the pawn controlled by my PlayerController.
The new pawn has another interaction event with the same button with consume event unchecked, which returns control to the original character.
Both input nodes are on the PlayerController and not on the pawn blueprints.

The problem is that I can't have either of them consume automatically, since that would cause whichever is called second to not happen; But if I don't consume then both will get triggered in the same frame and end up passing control to the second pawn and then immediately taking it back.

My question is if there's a way to have the consume event checkbox unchecked like this, but then manually decide to consume it via a blueprint node/CPP function.

(I can just delay the successful interaction by a frame so that the unsuccessful interaction can fail before the state changes, and that works, I was just wondering if there existed a way to consume the event in the first place)

[tight pollen]

I know that I am asking you a lot, but could you send me a screenshot of what it would look like, because I do not fully understand

I tried to do it, but something goes wrong

[mental trellis]

Ignore what I said there.

ChacterThatGotShot->GetRotation->UnrotateVector(IncomingShotVector)

Then compare the Y value

Just as a byproduct of doing that

Abs(y) > Abs(x) means it's from the side.

[trim matrix]

@brazen pike hey im back

do you have any ideas how to fix

[tight pollen]

it does not work

[mental trellis]

In what way?

[barren flower]

Do you just mean when he leaves the box?

[woeful pelican]

Do you know Source games?

[barren flower]

A bit

[crude isle]

is there a way I can do multiple stuff on Event Tick

bcuz it only lets me connect it to one thing

[gentle urchin]

Sequence

[trim matrix]

@brazen pike

even with this

doesnt work

[woeful pelican]

In a sense, maps in source games are a series of rooms. There is no 'outside' to these rooms, and can't do collision updates when it cannot find the world around the player.

[crude isle]

u meant that to me or what

[trim matrix]

I feel like the the clear and invalidate timer by handle node is messing things up

[gentle urchin]

Ye

[crude isle]

alr

well what is sequence

I'm new to blueprints lol

[gentle urchin]

Test it

Find the node, see what it looks like

[crude isle]

ohh

Well is there a way I can do it all at the same time

like not in order

[barren flower]

You can still do subtractive BSP in unreal

[gentle urchin]

Its always in order

[earnest tangle]

You can but there are quite a few gotchas with BSP meshes :P

[mental trellis]

You don't need the dot at all.

[barren flower]

But in answer to your question, if you are using meshes then you just have to create a volume for the playspace and just do a check that you are overlapping one each second or whatever

[crude isle]

like what if I want 3 separate things to happen at once

[gentle urchin]

You cant

[crude isle]

oh

crap

[gentle urchin]

They can happen the same frame

[crude isle]

I see

[gentle urchin]

Like

In sequence

[crude isle]

Oh

alr

[gentle urchin]

Which is percieved as at the same time

[mental trellis]

@tight pollen

[tight pollen]

still doesn't work

[mental trellis]

What happens now?

[tight pollen]

it is enough for a light shot to hit the back of the character and the value changes to what should be on the other side

[mental trellis]

Shrug that is correct code that that section. I don't know what the rest of your code is doing!

[trim matrix]

hey guys

does anyone know why this is not working

the new value for the timer on the Set Timer by Function Name never gets set

even if number of attacks is greater than 1

and I clearly see the value for the number of attacks variable go up with a print string

so idk what the issue is

[tight pollen]

i used Get Right vector from Bullet and from Hit Actor and then Dot product < 0

and it seems to be working

I just don't know if it's correct

[mental trellis]

Good good!

It's probably because unreal.

[tight pollen]

it is something like for Forward and backward 😅

[mental trellis]

Hehe.

If you wanted to use forward vector, I guess you could switch to checking the x value instead of y.

That'd make more sense if you're looking at the code.

[tight pollen]

but it can also be so?

like i made

[glass stump]

How do I change a material instance parameter in a BP?

[undone surge]

would these 2 pins be interchangable

or it has to be specific

[boreal mesa]

the distance will be the same

[undone surge]

ok

[mortal wharf]

I want to sort an array of locations by their angle to a center actor (so the elements are ordered clockwise from the center actor) 🙂 How would I do that?

I don't see a blueprint node to sort by predicate 😛

[boreal mesa]

probably time to resort to C++ lol

[mortal wharf]

aaaaallllriiiight.... 😛

Seems like it

[fallen glade]

is it possible to find everything used in a project from a library like this?

best way I can think of os the reference viewer but it doesn't tell me what's being used

[remote meteor]

hmm yeah this one you might need to find yourself within the referenced blueprint

[fallen glade]

how though?

just by browsing it?

[remote meteor]

kinda

the find in blueprint only searches for node/pin names and not their origin

so yeah need to manually search

[cursive musk]

https://youtu.be/TQsg8j-a3Y8 idk if im like vague explaining this, but ive ran into the problem when following this tutorial about sliding, maybe someone else had this problem too. I got all the blueprint steps right (i rewatched it multiple time :/ ) and my slide just doesnt function. When i try to slide is just slows down extremely and i cant uncrouch. everything else works, walking, crouching . Does someone know how to fix this by any chance?

[brazen pike]

well you can find the target as all of these are made in c++. For instance you can find this one in Kismet String Library and then searching the name of it. Then you can find all of the functions in the same file

Or do you mean only whats in the project?

[fallen glade]

that, yeah

[brazen pike]

hmmm yeah well might need to manually search like IAsaka said

[remote meteor]

sometimes they are very sneaky 😆

[remote meteor]

not very sure, can you show your crouch functions?

[rough iris]

will I be able to edit the values of the inventory reference I pass in inside the loop?

or is it creating a copy somewhere along the way?

[remote meteor]

hmm

you might want to

duplicate the for each loop macro

[rough iris]

or this is the right way to go about it?

[remote meteor]

change the Get(Copy) to Get(Reference)

or you can always after modifying,

set it back to the struct array

[remote meteor]

by default, For Each Loop in blueprint makes a copy when Getting the index item

you can change it to Get(Reference) but thats up to you

the Inventory Object is already a reference so its fine

problem here is the modified value isnt propagated back to the struct array from the for each element

[humble flume]

Hey guys I am making a mini map i am making it using texture my map is quite big I want that my map look like gta 5 mini map can anybody tell me how can I convert my image to gta 5 type mini map image

[rough iris]

how do I change Get(Copy) to Get(Reference) exactly?

[remote meteor]

you need to make your own for each loop macro essentially

you can double click the macro and see how its done

there is a Get(Copy) node inside

[rough iris]

in terms of the loop, I can just fetch the inventory reference and use the array index

that's not an issue

the issue is whether the setter sets the item correctly

I guess I worded it wrong originally

[remote meteor]

hm

it should modify it

[rough iris]

In this case, is Inventory a reference to the actual inventory component or is it a copy?

[remote meteor]

because all object are passed by reference

its the reference to the component form outside

[rough iris]

awesome

[remote meteor]

there is no "copy" function for blueprint objects

all blue variable you see in blueprints

are all references

[rough iris]

I thought the rhombus were references and circles were values

[remote meteor]

yeah

so the difference is

reference of reference vs copy of reference

in the end its going back to the same place

[rough iris]

gotcha, thanks

[serene crown]

Hi everyone 😄

I'm trying to make an endless runner, the runner only goes forward but I noticed that the game stops itself after a certain distance... is that normal? can't I make it infinite without turns?

[cursive musk]

yes i know ive done way to much for a crouch and a slide, im new to this and followed a long tutorial xd

[remote meteor]

i believe this part should be something like this

also the set movement state function please

[cursive musk]

what should i add in there?

[remote meteor]

reference back to the original video

that part is responsible to set your movement state back to walking when you release the crouch input

[cursive musk]

alright it fixed that it uncrouches me after the slide now but its still weirdly slow

[mental trellis]

If it works, it's fine. :)

[rose charm]

Hello, I'm trying to make a airship buildable on runtime, on which the player can build the airship with blocks and pilot it, but I don't know a way to update the collision of the airship (a pawn) and the new attached blocks keep passing through the walls. Does anyone know how can I do it?

[cursive musk]

it seems to slow me down in mid air too for some reason

[serene crown]

I'm very new but the only way I could imagine this working would be to have all the "Placeable blocks" placed down already in a "Dormant" state (invisible and with no collisions) and when you go to place down the block your holding instead of actually creating a new block to attach to the pawn you just activate the dormant block at that location... it's a bit a cheat but that how I would make it 🙂

[serene crown]

OH wait, maybe I have an even better solution, you could use this Node here:

[remote meteor]

An advice

dont use child actor component

unless you really have too

its too finnicky

[serene crown]

Using it rn... no problem for now, why are you saying this? What could happen? 😮

[red grail]

Anyone know why this god damn Set active node isnt receiving the input?

[icy dragon]

You're in for a huge trouble

Mainly referencing actors in question.

Spawning actors then do some attachment is far more reliable.

[rose charm]

the problem is that I dont know if there is a way to make a pawn with multiple collision, the only collision relevant for movement is the static mesh i have on the root, if I add more collisions on the actor these ones keep passing through walls

[serene crown]

It's just to place random obstacles on a endless runner... it's for a gamejam :/

[icy dragon]

Doesn't matter. Child Actor Components are bad.

So much so that I'll spank you for using it if you're working for me.

[serene crown]

Not if the blocks are part of the ship already with collisions turned off... I think

[serene crown]

Ahhh man... and I thought I found my new Favorite node... 😦

[serene crown]

Ohh I get it... I never tried that with a pawn... you might be right then :/

[icy dragon]

Are you using static mesh components "welded" together?

[solemn crescent]

I need a button to reposition a 2D card in front of the current camera position, with out parenting it;
if the camera moves it should not follow.
The card should face and fill the FOV.
How would I go about that?
I’m just getting started with blueprints.

[wise tide]

My settings menu has a return button which takes you back to the main menu. However you can also access the settings UMG from an in-game pause menu, where I would want the return button to instead return you to the main pause menu.

I don't want to create 2 different settings UMGs because then I would need to update both separately. Whats' the proper way to deal with this issue?

[rose charm]

I've changed the root mesh to a cube and now it worked, I was using a custom mesh before, I will check if the problem is in it

[icy dragon]

Why not having both main menu and pause menu use the same options menu widget?

[wise tide]

they do

but there is a button on the options menu widget which takes the user back to the previous screen, which is different depending on if the user is in the main menu or the pause menu

[icy dragon]

Already tried binding events for it?

[rose charm]

maybe you can try to save a variable with the previous widget

[tardy seal]

For some reason Vinterp To Constant still has some smoothing when it interpolates between different vectors. How can I make interpolation between two vectors be completely linear?

[wise tide]

I don't know what binding events are

[icy dragon]

https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/Blueprints/UserGuide/EventDispatcher/BindingAndUnbinding/

[faint pasture]

How do you know it's not linear?

It should be.

It's velocity linear. It'll lerp at x speed towards Target from current

[fickle ermine]

not sure if this is a problem with my blueprints or how im setting up the scene, but ive dragged in a couple of my coin actors and any beyond the first one wont respawn when i set their 'ishidden' boolean to false

do i need to give them individual variables or something? im very new

[trim matrix]

I created an anim notif here

in my anim graph
and im trying to get a ref of the variable start taking damage in my other bp

the function never gets triggered

supposed to take away 5 health from the player
every time the anim notify is true

[tight pollen]

How can I make a smooth transition from Animation to Ragdoll?

[wise tide]

Is this what people usually use for this issue? I assume there is a tutorial for my specific issue as most games have to deal with it, but I am struggling to find one. Also I am not fully understanding the event binding stuff after watching a couple tutorials

[obtuse yoke]

I made this little course by placing things separately to test it out. but now i would like to move it all to a BP actor so I can spawn it as a whole wherever I want. How would I do that?

[icy dragon]

Well, I personally use event dispatchers in the same context

[undone surge]

im trying to calculate the distance between 2 ai characters but it only starts changing only one of them moves

[zealous moth]

@undone surge how are you doing it?

[undone surge]

it only changes when the actor from class moves. the one i am comparing distance to is an ai controller

do i have to associate it with controlled pawn ?

nvm i think i answered my own question

[undone surge]

THANKS!

[zealous moth]

Omg what am I looking at????

[undone surge]

idk

[zealous moth]

Why is there no specific actor? What is the event trigger? Tick?

[icy dragon]

:NotLikeThis:

[undone surge]

yes

look it works now ok xD

[icy dragon]

That happens on Tick?

[zealous moth]

Going back to graphics, see you there @icy dragon

[undone surge]

all this

[dark crow]

Delicious spaghett

[undone surge]

yes

[icy dragon]

I mean, you do you.

[undone surge]

xD

[tight pollen]

Someone can help?

Some idea?

[undone surge]

i just want to get it working then i will fix shit

[icy dragon]

Understood

[hearty barn]

I'm rotating the player to look to the left of his velocity and this works if the ship is going to the right but if the player turns 180 and goes right this doesn't work what am I missing? the crappy drawing may better explain what I mean

[undone surge]

what is the correct way to spawn multiple AI actors ?

[brazen pike]

woah maybe dont get all actors of class on tick

[undone surge]

yea yea im not

[brazen pike]

Ah I've seen it wrong

[trim matrix]

#blueprint message

can anybody help me pls

[undone surge]

this is how i spawn 1 @brazen pike

[cerulean palm]

I have a map of string to struct{array<string>} in BP,
I need to find a struct against a key string, and then add another string to the array member of the value struct,
but for some reason the added string isn't stored in the map array member,
does the "Find" node return the struct by copy?

[undone surge]

how willl i do multiple

[brazen pike]

use the for loop

Do you want a reference to all of them?

[remote meteor]

Yes

[brazen pike]

Maybe use an array

[cerulean palm]

crap

[remote meteor]

Just add it back once u done modifying the map

[cerulean palm]

will using an uboject work?

[remote meteor]

Since you have the keys and updated value

Add will replace existing copy in map

[cerulean palm]

Okay, so essentially it'll replace the value and the full array within everytime

[remote meteor]

Yeap

Unless you do it in c++

[trim matrix]

anybody???????

[remote meteor]

Then you can modify it by reference

[cerulean palm]

"Find" Behaviour is same even if I use an UObject BP instead of the struct, right?

[remote meteor]

Yeah but since it is an UObject

Hence it is a reference

So values will be updated

[cerulean palm]

yay

[remote meteor]

Not sure but from your second vid it appears the boolean is false?

You sure they are fetching the correct values?

[trim matrix]

nothing works

[remote meteor]

Its condition racing

The execution ran before you updates the bool to true

[trim matrix]

I want 5 damage to the player everytime the anim notif is true

[remote meteor]

Just call it at the anim notify to deal damage?

[remote meteor]

Are they the same anim bp?

[tight pollen]

Refresh

[trim matrix]

this is in the anim bp

and this is in the AI

[remote meteor]

When is this called

[trim matrix]

It wont let me get the mentalhealth function in my anim bp

[trim matrix]

when the anim notif activates

[remote meteor]

??

[remote meteor]

Let me see the left side to this

The only thing you did on anim notify is setting a bool to true, nothing else

Youre not gettinf ur function because the branch check for the bool happens earlier that it is being setted to true

[trim matrix]

fk

[remote meteor]

Also i dont get why not just straight up call the damage function from ur animbp

Why go through a bool?

[trim matrix]

wont let me

[remote meteor]

Bruh

[trim matrix]

?

sry im new

you have to forgive me

[remote meteor]

Make a event dispatcher in your abp, call it on anim notify

In your ai,

You have the reference to your abp

Bind that event dispatcher

During begin play or something

Then deal damage from there

[undone surge]

if i dont reference to each would their stats be used ? like if i use a variable from the class like health or isdead then will each spawned actor carry their own stats ?

[trim matrix]

@remote meteor

❤️

IT WORKS

[remote meteor]

Or you also can explore on this

[trim matrix]

THANKS!

[remote meteor]

You can use GetOwner on the MeshComp

To get the owning pawn

Then call the deal damage from there

[trim matrix]

it works perfectly like this
