that worked for the minigame but for ui that has input setup the same way would i need to do the same enable input or is it different

[sharp ferry]

is it difficult to make an animation of my character start (idle animation) when my character grab and hold a box?
now i already have a idle and walking animation on her
but i need to add this idle where she has the arms lifted up to hold the box

[lofty rapids]

if you do something like this then just add a web directory in the director that the exe is in

and then you got access to the files

but a server is better all around

[vagrant slate]

Thanks I'll try that next!

[lofty rapids]

i find it easy you can just keep a folder for your web stuff, but i wouldn't use this function in development

it's a wild directory and not what you want to work with

but perfect for a packaged game

theres some stuff in c++ you can use to determine if your in shipping or not

but in straight bp i don't know if thats possible, probably just a boolean branch

some boolean like isDevelopment that you'll need to switch on and off

and replace launch dir, with your dev folder

it's the best way i have found to mess with files, two different modes

the directorys while your in editor are just hard to use in comparison

[vagrant slate]

hmm I can't seem to construct that format text node- was there a trick to it?

[lofty rapids]

so you got the format text node ?

[vagrant slate]

yes

[lofty rapids]

the things that you can plugin to on the left

those are in the string as {variableName}

[vagrant slate]

I just have the format pin and text box

[lofty rapids]

type whats in the picture and press enter

[vagrant slate]

oh lol

thank you!

and the page to open?

what's the format like for that string?

[lofty rapids]

filename.html

whateverTheFileNameIs.html

[steady night]

How can i get nav ontop of the statuic meshes ?

since if i stand on it the AI cant detect me

[vagrant slate]

new guid doesn't want to connect to the pin for some reason?

[lofty rapids]

it won't auto convert, you need drag out find: to string

then plug that in

[surreal peak]

Increase the nav volume height?

[vagrant slate]

yeah I definitely tried that

[lofty rapids]

are you saying you couldn't find tostring ?

[vagrant slate]

I can find it but it just pops out disconnected

[steady night]

i have, but im guessing the objects are "to small" or can i adjust the hell size someghow +

[lofty rapids]

you don't have this ?

[surreal peak]

Could be too small, yeah. You can test by increasing the collision a bit

[lofty rapids]

what version of unreal ?

[vagrant slate]

5.4

here's where I'm at

[lofty rapids]

click on the return value of new guid, and drag out

then search for to string

it will give you the relative nodes for things when you drag out from them

[vagrant slate]

yeah did that from the start

[lofty rapids]

instead of just getting a new node

[vagrant slate]

also tried it the reverse way for all of them

[lofty rapids]

ya thats really strange

idk what it wouldn't show up and work

maybe restart the editor try it again

[vagrant slate]

oh i may have found it

it's to string (guid)

[lofty rapids]

but if you drag out, you should see to string(guid)

yep

[inland walrus]

Anyone know how to add line breaks via datatable?

[vagrant slate]

I have adhd so I may have just missed it

[lofty rapids]

thats the one

[lofty rapids]

does shift enter not work ?

[inland walrus]

No sirr

[vagrant slate]

thanks for the help- building now- fingers crossed

[inland walrus]

Found it! you need to checkbox on the struct "multiline"

[steady night]

yeah had to make it like 2/3 times bitter for it to sense it :/

[floral stump]

you make the collision channel of you character to be blocked by the vehicle, when vehicle hits the character you add linear physics force to the character move in the forward vector direction of the vehicle

[vagrant slate]

"Failed to load URL file:///Z:/.../Windows/web/75D258A34AB6578FCD1ECC8CAB84E186?uuiid=1-21-25.html with error ERR_FILE_NOT_FOUND (-6)."

Any ideas?

[lofty rapids]

ya you plugged the uuid and filenames into the wrong ones

[vagrant slate]

whew I hope that fixes it! ok rebuilding!

thank you!

[vagrant slate]

YOU GLORIOUS GENIUS YOU

IT WORKS

[steady night]

@surreal peak Can i amke it so the player slides off the mesh instead, like making the collison to a triange

[vagrant slate]

I have been working on this for 2 days

/frodoitsdonememe

[lofty rapids]

just when you dev, i would suggest using launch dir to dev with

when deving use a dev folder

and just switch it out with launch dir when you package

it's kind of a pain in the ass, but best way to do it imo

you can like i mentioned also with c++ choose depending on if your in shipping or not

[vagrant slate]

seriously I appreciate the help

[lofty rapids]

np, i enjoy helping when i can

[vagrant slate]

you really are willy wonka

handing out candy bars

[lofty rapids]

well i just happened to be working on it as well lol

[uneven crest]

This may sound wierd or hard to understand but, im creating a baseball game. I have main parent class that just has basic settings like name and rating and position. In each child class, i set the values for those 3 in the defaults. I then have a structure with each player actor as a variable. Im not able to get the information from the actors though like the rating. Is there a better way to do this? I can show the code I have if needed

[lofty rapids]

what is this structure ?

with each play actor as a variable ?
wdym

if you want to pull all the data from them

get all actors of class of the parent, this will get them all in an array, which you can loop through and use to populate whatever your doing

since the variables are in the parent, it should work just fine

[uneven crest]

Mason Vicker is the player

[lofty rapids]

so are you this way going to add player references to this ?

each player an individual reference ?

[lofty rapids]

so name is not working ?

[uneven crest]

Yes

That error comes up

[lofty rapids]

yes because you have not actually filled that reference

you need to point the variable to the ref

by setting the variable

just setting the type won't set it to the proper refence

[uneven crest]

Even if i set the default in the structure?

Which i cant i just realized

would it be better to just store each players attributes in the struct instead of child actor

[lofty rapids]

i would construct the variable like this

passing the references for each player into the make

if you want to keep this structure

do this at some point in begin play when the players are loaded

usually things like this are stored in an array

[lofty rapids]

do this when your people are loaded in the scene if you want this data structure

but honestly i would have an array of the parent class

but you can form your data however is clever for you

[lofty rapids]

yes it would better to not have a bunch of references in your data if you can

so if you only need those values as data then you can just store them in something like a player struct

unless you want to be able to look up the references in the structure

i would have a couple arrays

one for team A, one for Team B, and in the team struct just pass in an array of parent class objects

so instead of all your players all different references

[uneven crest]

Ok thank you

Data table you think becasue each palyer has 4 ratings that contribute to them?

[lofty rapids]

why do you need the data table ?

i never used one before but I see it used on here a lot

[uneven crest]

Im thinking its easier because on each team, there are 14 players. Each player has 5 float variables, and an enum attached to them

[lofty rapids]

storing the raw data is better then the references if you can avoid it

unless the references are parent class

thats not too bad, but i suppose it wouldn't matter as all players are probably loaded

but if you were to do this for all teams, you would just make the two structs for the game

this way you would need a seperate struct for each team

[lofty rapids]

whatever works for you, data can be structured in several ways

[lofty rapids]

i would personally do this

if i was making player stats

a bunch of these for different teams

every team would essentially have one of these

then you could look up players pretty easy and fast

[hardy merlin]

I've got a struct variable with a large amount of data inside it. What's the easiest way to change one specific piece of it through blueprint?

[maiden wadi]

SetMember function

[hardy merlin]

I want to avoid using Break and Make and linking every single variable, especially if I add more.

Then what?

[maiden wadi]

Select the node and look at the details panel.

[hardy merlin]

Found it. Thanks! This rocks.

How long has this feature been in the engine?

[maiden wadi]

Longer than I've been using it at least.

So, more than 5.6 years or so

[rapid stag]

Hi everyone, might be a simple question, but can you have different interactions with compnents in the same bp? I have an interaction interace setup that activates on E being pressed, and want to know if different compnents can be interacted with to do different things.

[dark drum]

Sort answer is yes.

[rapid stag]

Does it make more sense to just make instances where i change the mesh and what happens with editable variables?

[hardy merlin]

Probably.

[maiden wadi]

The only real answer to that question is personal preference. Depends on how you feel you would like to set things up.

[agile moss]

I want to trace a line from the player to where he is looking, one problem, idk how to find the end result

[lofty rapids]

from the center of the camera straight out ?

[maiden wadi]

StartPoint = CameraLocation
EndPoint = CameraLocation + (CameraDirection * TraceDistance)

You can get direction by getting the camera rotation and doing the XVector function I believe.

[lofty rapids]

i usually get the forward vector multiply it by the distance

[maiden wadi]

But you still have to add the start point back to it. Or your end point will be an offset from world zero.

[agile moss]

yeah, that is what i was thinking too, just can't get this right every time I do this. it's like the 5th time already I do one of these XD

[maiden wadi]

that is mostly correct, but don't get the rotation of the component. Drag off the camera manager and GetCameraRotation.

[agile moss]

alr alr, thx

[hardy merlin]

Or get Controller View Direction.

[maiden wadi]

Where is that function from?

[agile moss]

this seems kinda much for a weapon swap system, any other aproaches? (expample: if holding secondary weapon swap that weapon)

nvm it's perfect

[void crescent]

I would say it is too less. 🙂 It's not even connected yet. You might tell your animBP that you wanna swap... wait until some anim notify says the current weapon is unequipped or in inventory so equipping the new weapon is fine and may play it's equip anim montage until the notify says it's ready (and may be fired) probably do some switch authority checks so a player does not by "mistake" swap his empty weapon with a loaded from his enemy and some is player dead checks. 🙂

[agile moss]

idk, problems appear, I'll solve when they get in my way

[stark inlet]

Hey guys, I'm just wanting a bit of guidance/help regarding this short game im making. It's going to make use of portals and have a similar system to Spyro where you need to collect items in each level to complete that 'world'. But I'm not sure how to use the portals. Do I have them teleport you to an entire different level to collect the items there or will it just teleport you to a different part of the main map (obviously I'd have to design the seperate parts quite far out). My concern is, how do I teleport to different levels without you losing your items or progress ? (I worry that teleporting will cause each level to restart when that isn't my goal). Sorry if this doesn't make much sense, never made a game before 💀

[uneven crest]

Got an issue. I spawned an actor and possessed it, but no funtions like left mouse button are working within the pawn. A little help?

[faint pasture]

Show your code

[hardy merlin]

You probably want to use UObject instead of Struct.

Especially if you're swapping often.

[agile moss]

Ok, I will look into them

[mystic umbra]

hello everyone!

i'd like to try optimizing the Instanced static meshes caves generation system using instanced static meshes. they are made of cubes ( 12 Triangles )

i have tried using CPP and multithreading. but i still get stutters when the world generates ( + extreme usage of memory )

would love to discuss about that

i have tried generating the caves slowly but this took an entire minute and a fest of stutters and frame drops. im trying to make this in realtime

[sick sky]

Maybe ask in #cpp ?

If you use a lot of loops BP is going to be a bottleneck

[mystic umbra]

Thats why i have switched the code to CPP

[sick sky]

How much

[mystic umbra]

all of it

i dont think its an issue with CPP either way. its probably how the editor generates instanced static meshes

[sick sky]

Profile

And see what takes time when you generate

Cant play guess games here

[mystic umbra]

adding instances cant be multithreaded. otherwise it crashes. it needs to be returned to the game thread. which is causing the issue

that said im not really sure how to profile such thing OR memory

Look i really apologize for being stupid. my english is not that great and im relatively new here

[sick sky]

#profiling

See how to use the basics of the profiler, and see what is really expensive

You can add custom trackers in your functions to see more details in your code

[mystic umbra]

i will try and give back feedback

[faint pasture]

That is a metric assload of instances. How many? Over a million?

[mystic umbra]

Yeah. its fine on my end. its only spawning them ( even slowly ) thats causing stutters. im trying to make this realtime

[faint pasture]

Show your code for spawning them

[mystic umbra]

void AVoxelGenerator::Spawn3DVoxels()

[dark drum]

Are you using a single instance static mesh component and have you implemented chunks?

[mystic umbra]

my code is not full. the 2nd part is not sent for some reason

[mystic umbra]

i have 2 of them. and yes i have implemented chunks. each chunk spawns it cubes. after its done the others can start working

[dark drum]

You most likely need more instance static mesh components.

[mystic umbra]

what do you mean? all of the cubes are instanced static mesh components

the blueprint part is not an issue when it runs

[dark drum]

You start to get degraded returns when adding new instances when the count is high. (Usually around 10k for me but would most likely vary from machine to machine) The time it takes to add and update when adding a new instances takes longer. Splitting across multiple static mesh instances components tends to be a good solution.

[dark drum]

Wait, so you're not adding an instance and instead creating a new component for each cube?

[mystic umbra]

No. this only happens one to initiliaze the components

when spawning the meshes. i get them from an array ( which consits of 2 values )

[dark drum]

Personally I would probably have 1 instance static mesh component per 4x4 chunk area. Maybe even a 2x2 chunk area.

[mystic umbra]

each actor generates 5 by 5 by 5 cubes.

i have tried playing with the numbers but no luck

[dark drum]

So you have an actor per 5x5x5 cubes? Actors can be pretty heavy when spawning in mass.

[mystic umbra]

it depends. i have tried having 4 actors ( 30 by 30 by 30 ) and i have tried 20 actors ( 10 by 10 by 10 )

however i put a delay between each of the actors so they dont all start spawning at once

[mystic umbra]

are instanced static meshes the best to do this either way?

[faint pasture]

how many times is this BP code called?

[mystic umbra]

depends on the amount of actors in the scene. each actor calls it only once

so usually between 10 to 20 times

[faint pasture]

So where is the time spent?

You need to figure out how long your voxel data takes to generate, and then how long it takes to get a chunk from voxel data to instances

[mystic umbra]

i tried asking a friend before. he told me that Adding instances in general is a little heavy and cant be multithreaded. and that it needs to be on the game thread

its probably in the CPP side

[faint pasture]

time it

[mystic umbra]

Using the profiler?

[faint pasture]

yes, you can put your own scoped profiling stuff

Although you can probably just do it from BP to be honest, just do something like:
ButtonInput -> record time -> call into C++ to do the generation -> record time -> print

For example this is my tracing harness for something in my game

[mystic umbra]

Oh you mean how long it takes for an actor to spawn all its instances?

( Good luck on your game bro ^^ )

if so then give me a second

Not the best naming possible xD

[faint pasture]

i mean scope out how long it takes for the all the parts

so you can see where it's slow

none of that looks slow, 6 ms to add like 100k instances doesn't seem nuts

[mystic umbra]

im looking for tips in general to optimize the generation even more. i get even better results when disabling collisions. but im looking to squeeze more ^^

[faint pasture]

your best bet is going to be not using 1 instance per voxel

[mystic umbra]

you mean per actor?

[faint pasture]

how many instances total does your scene contain?

instances, not actors, not components, instances

is it 1 instance per voxel?

[mystic umbra]

16 by 16 by 16. for 20 actors

about 80K

[blissful dirge]

super noob here, I'm placing a bunch of trees in my level, these trees all have a variable referencing another actor in the level, what's the easy way to set that variable so every tree references the same actor without having to set it by hand every time I add a tree to the level?

[faint pasture]

how many instances are in this whole scene

[faint pasture]

What are you actually trying to do here, what actor are they referencing and why?

[mystic umbra]

i dont remember. i changed some values

IIRC the original had the depth of 3. so 16x16x30x20

30*

[blissful dirge]

It's an event dispatcher, it broadcasts events to the trees

[mystic umbra]

i tried playing around with the value of the first two digits ( X , Y ) and increase the amount of actors. same stutters, same time

i thought it could be because there is too many instances spawning per actor but it doesnt seem to make a difference

[faint pasture]

And how many trees do you have?

[faint pasture]

Gotta profile it to figure out where the time is

[blissful dirge]

I have one right now, I want to add hundreds or thousands

[mystic umbra]

i'm bad it CPP. so its taking me some time to mark those in the profiler

[faint pasture]

And what event is being dispatched, season?

You don't want the trees to be actors with their own code for this, have a thing that just updates trees instead

[charred oyster]

Hi, I'm new to Unreal Blueprint and I'm kind of struggling with something right now. I have a game where I have to make a cube fall when shooting a projectile at it. I working on the lose condition that happens when you have no more projectiles left and the cube has no velocity. Currently, I know when the player has no more projectile and I display the lost screen. What I need to do, is to do a constant check of my cube velocity once the player shot his last projectile (If you know what node can be used for that, it will already help me). Then, if the velocity drops to 0 (with a threshold to prevent softlocks), I wait 1 or 2 seconds just in case while continuing to check the velocity (this is to prevent wrong true statement like when the cube is send in the air and he reach his max height, velocity will be 0 but the cube can still touch the floor). If the cube has velocity again then I continue the permanent check and if the cube has no velocity, I wait for 1 or 2 seconds again just to be sure. I also need to add a max duration to the whole thing. If the cube velocity is 0 or if the timer reached the max duration the player lost.

If you can give me a clue on which nodes could work for me or need more details, reach out here or in PM :)

Thanks to anyone who can help me

[dark drum]

Wake and Sleep events might be what you're looking for. It triggers an event when the physics objects is put to sleep (due to having no velocity) and when it's woken up again (when it starts moving)

[red topaz]

Hello folks! I would like share my tutorial about Finding Blueprint code changes within version controll commits In Unreal Engine finding the blueprint code changes manually is time consuming. Compared to text based programming languages like c++ , C# , unreal blueprint codes are not in text file when saved as a file. They are in binary format. Hopefully using "UE Diff tool" + version controll system, it is one click to find the code changes on a blueprint code or parameter changes withing version controll commits or any other files that are manually migrated into the project.

https://youtu.be/tl8rcQ4hjAA

[charred oyster]

I see, thank you very much. This is exactly what I need !

[dark drum]

Does anyone have any suggestions on how I could get the start of the line to hug the outline of the mesh? The outline a PP material using stencil buffer. The line is using the draw line function between two anchor points that I can move around.

In summary, how could I get the world location (or screen space) of the edge of the visible mesh?

[lofty rapids]

have you tried the bounds of the actor ?

i think if you need it screen space, once you have the bounds you can convert it

[dark drum]

Yea, I've tried using the bounds but it either ends up inside the outline or away from the outline depending on how it's being viewed.

[lofty rapids]

`

i did this and it seems to have places the spawned actor at the edge of the component

[lofty rapids]

thats a bummer, i thought it would work for ya

i spawned the blue ball at that point

that puts it in the center, you can use y as well to get it more to the front

[dark drum]

Yea, with where the ball is, the line would start inside the outline. I guess a better description of what I'm wanting is to get the point along the edge of an object silhouette.

[lofty rapids]

idk what you mean by solhouette of an object ? but using the bounds and adding an offset might get you there. and like i mentioned if you add y to then you get the outside front edge

[dark drum]

I've also trying getting the closest location on the collision which seemed better but there were still times the point would end up in an odd position.

[lofty rapids]

something like this point ?

[dark drum]

https://en.wikipedia.org/wiki/Silhouette

[lofty rapids]

oh geez, you want a point along the head ?

[lofty rapids]

could you maybe draw a bunch of line traces in a row untill it misses ?

[dark drum]

Not the head specifically lol. That's just an example of a silhouette.

In the case of what you showed it would be the point at the edge of the black bit.

[lofty rapids]

i think this would work

if you shot a trace from the camera to the center of the thing

and then just moved it over a bit for abunch of tries

untill it misses

sounds a bit much but could work to do this

i don't know how fast it would be for when you move

it's just a quick thought might be worth a shot

[dark drum]

This is what the stencil buffer looks like that's used to make the outline.

I did think of using line traces but yea, it seems a little over kill. I might give it a try though.

[lofty rapids]

you could also try to get all the areas + bounding, then calculate the right most or left most or whatever you want one

you w ould have to turn them to screen space first

then check for the right most point

might be more efficient then a bunch of traces so close together

[dark drum]

hmmm yea sampling a few points and finding the one furthest way (in screen space) is a good idea.

[naive egret]

Hey how do you make a 3d widget appear based on click with blueprints?

[lofty rapids]

https://streamable.com/pj870q

[lofty rapids]

is the widget on your player ? or some other character

[lofty rapids]

do you want to click on an actor ? or just whenever you press left mouse button it goes on and off

[lunar coyote]

In the BP editor, does right clicking to bring upp the node menu also cause UE to "repopulate" the list every time for you guys? For me, I see a blue bar and nodes being added to that menu. It only takes like 0.3s every time, but it's still annoying. It used to just have all the options instantly before.

[lofty rapids]

is your computer making a lot of noise ? are you on windows ?

[lunar coyote]

Noise no, only on 30% gpu, 10% cpu. Windows yes

[lofty rapids]

interesting i was going to say check the task manager, but 10% cpu thats weird it's taking time

and you restart the editor ? nothing changes ? what about a blank project ?

[lunar coyote]

@lofty rapids I'll try. So that doesn't happen to you too?

[lofty rapids]

no it's pretty fast actually

i don't see a blue bar at all

sometimes it takes awhile to load on a big blueprint

but usually it pops right up

[naive egret]

I want to click on an actor specifically

[lofty rapids]

go to the actor, in the details all the way at the button there is on clicked

[naive egret]

the Widget is on my Actor in its BP class

[lofty rapids]

does this work ?

[naive egret]

nope

[lunar coyote]

@lofty rapids It still happens in an empty project. I mean it's fast, just a fraction of a second every time, so it's not a problem, but I'm just baffled by it lol. It used to be instant in previous versions. But this isn't the worst performance issue at all so it's fine.

[naive egret]

I added breakpoints aswell its not being triggered at all

[lofty rapids]

did you enable click events in your player controller ?

[naive egret]

I don't think so

[opaque geyser]

Hello, I am working on a project that involves gravity manipulation. I'm trying to make a system that smoothly trasnition from one gravity oreintation to the other. (If you just set new gravity direction it snaps to that direction). My code seems to work very well untill the last second. If starts to jitter the character. At more extreme changes in gravity (like flipping totally upside-down) it jitters even earlier and never reaches the new orientation. Any ideas? My math could very well be flawed.

[lofty rapids]

do that, it should work

[naive egret]

this right I just enabled it

[lunar coyote]

@lofty rapids oh you know what I think it is? Editor Preferences > Blueprint Editor Settings > Advanced> Context Menu: Non-Blocking Per-Frame Threshold (ms).

By default it's at 50. if I set it to 1, that context menu takes forever to populate, if I set it to 1000, it's a short delay to open that menu but it's populated when it opens. I assume that value was something like 150-200 in previous versions, so that's why I didn't notice that delay in earlier versions.

[naive egret]

did that still doesn't work anything else that needs to be enabled?

[lofty rapids]

not that i know of

[lofty rapids]

are you setting the game mode anywhere ?

[naive egret]

this is? this is for my main level

[lofty rapids]

i mean thee node set game mode ui or anything ?

theres set game mode ui, set game mode only, set game mode an ui

are you using any of these anywhere ?

[naive egret]

where do I see that?

[lofty rapids]

it would be in your bps somewhere, could be anywhere but probably on a begin play if so

[faint pasture]

that math looks borked

[opaque geyser]

I just simplified to this, but it is still probably wrong! lol

I'm definetly not a math expert

[faint pasture]

just use current as current, and set target to be MakeFromZX with Z being gravity and X being current forward

[naive egret]

this is the BP I don't see it anywhere

[faint pasture]

that'll enforce up as being gravity, and x being as close to previous x as it can get

[naive egret]

tbh im kinda new at this idk what im doing half the time

[lofty rapids]

it takes time to practice and learn, i'm still learning all the time and i've been using unreal for a bit of time

on and off atleast

[lofty rapids]

what does you character begin play look like ?

[opaque geyser]

Like this, cause this definitely isn't working, lol

[faint pasture]

that's not at all what i said

have current rotation be the literal current rotation

[opaque geyser]

Wait, yea, it's not

[opaque geyser]

Oh gottcha

[faint pasture]

have target be MakeFromZX(-Gravity, CurrentRotation.Forward)

[lofty rapids]

do you even see a mouse cursor ?

[lofty rapids]

here in your controller, enable show mouse cursor

[naive egret]

ok and?

[lofty rapids]

did you have a mouse cursor before ?

[opaque geyser]

Like this, lol

[naive egret]

yes

[lofty rapids]

or when you click it went away ?

[naive egret]

it is there

enabled it when I enabled on click

[lofty rapids]

ok, and your sure your using that player controller ?

[lofty rapids]

ya can't click without the mouse, but was the mouse showing before you did this ?

[opaque geyser]

Lol, that's not working either @faint pasture

Hold on

[naive egret]

LEMME CHECK RQ

sorry for caps

[faint pasture]

Make sure rotation isn't being clobbered or set by anything else, also CMC doesn't like non-vertical oriented capsules btw

[lofty rapids]

because if it was, you may not be using the right controller, and enabling things won't matter r if it's not actually in the gamemode override

[opaque geyser]

It isn't, I learned about capsule rotation the hard way, originally was just trying to set capsule rotation. With setting the gravity, CMC doesn't count the capsule at rotated because the bottom of the capsule is always facing gravity, hence whhy I'm changing gravity in order to rotate and turning gravity off untill the desired gravity is reached

[faint pasture]

does setting gravity cause the cmc to orient the capsule?

[opaque geyser]

Yes, the capsule snaps in the direction of the new gravity which I why I am trying to smooth out the transition. Normally if I set a new gravity direction my character will just flip to face the new direction

[faint pasture]

ok so just smoothly interpolate that

[lofty rapids]

how to change the gravity direction ?

[faint pasture]

how does a VInterpTo on gravity behave?

[opaque geyser]

That's what I'm trying to do, interpolate between my current gravity direction and the gravity direction I eventually want to reach

[opaque geyser]

It was added in 5.4 I believe, it's just a node for character movement that sets the gravity direction taking in a vector. To get the camera to work properly, it requires a c++ class. (which I have)

[opaque geyser]

I tried Vinterp earlier, could've still just been a me thing, but it was basically doing the wierd shaking thing, but the entire time, it never got anywhere

[lofty rapids]

another reason to upgrade ig

i have 5.3.2

so i can't get this node

[opaque geyser]

Wait, I take that back, the problem with that was that if the gravity exactly 180 degree change, then it would only change that one value of the vector resulting in a snapped flip once it finally reached the other way instead of rotating. So that's why I started with rotators rather than using vectors. It's a shame, cause if it weren't for that, it would work perfectly

[opaque geyser]

Oh, lol, yea, it's vey nice when it works

Yea, it's 5.4, this was the documentation/tutorial when it released https://dev.epicgames.com/community/learning/tutorials/w6l7/unreal-engine-custom-gravity-in-ue-5-4

[naive egret]

it is using the same controller I just verified

[lofty rapids]

somethings blocking the click

do you have a main widget at all ?

[naive egret]

nav mesh?

[opaque geyser]

I think Adriel gave up on me, lol

[lofty rapids]

i don't think that would stop the clicks, if you had a widget that was on the screen and blocking then that might make sense

[naive egret]

Main widget as in something that is there in the level when game begins?

[lofty rapids]

as in a user widget like a hud or something, a main widget that you added to the project

[naive egret]

there is this

[lofty rapids]

ya this

[lofty rapids]

in your players begin play, set input mode game and ui

[naive egret]

From this I need to set default?

[lofty rapids]

if this doesn't work, then somethings probably on the widget full screen blocking

[naive egret]

ok imma try it out

[faint pasture]

Is your gravity always the same strength?

[opaque geyser]

Within the rotation yes. Overall, no. Before it starts I set it to 0 so I don't have to worry about it trying to "fall" with gravity as it changes and then one the final direction is reached and the "rotation" is finished, I set it back to default.

[naive egret]

I should add the widget aswell right?

[faint pasture]

You can try SlerpVectorToDirection with your own math to make it the same behavior as vinterpto

or just maintain a rotation and rinterpto it all the time and set gravity based on it, might have some artifacts though

[lofty rapids]

you could put itt in as focus ig if thats what you mean as "add" it's already added to viewport

[naive egret]

ok

[opaque geyser]

Unreal is deciding to be choppy on my seond rate gpu, but I think that may have just worked, one moment

[naive egret]

something is blocking

[lofty rapids]

show the widget

[lofty rapids]

is the widget mouse stuff working like clicks on the widget ?

[opaque geyser]

@faint pasture Thank you so much, that did just work. I've been working on that for a LONG time. Migrated to MOVER for a short while so I could rotate my capsule, it was an awful experiene. Thanks, that was days of my life, lol

[lofty rapids]

click on overlay

[lofty rapids]

this doesn't look like the right widget though

[lofty rapids]

you want the main widget that you add to viewport, is this the whole thing that creates all the stuff on the screen ?

[naive egret]

oh wait

this one right?

[lofty rapids]

check the visibility of the containers

i think this might be a thing for widget reflector, i've never used it before but i heard you can see what widget is getting the inputs with it

[naive egret]

hmm

you think this hud is blocking the mouse from clicking the actor?

[lofty rapids]

ya, tools, debug, widget, reflector

[naive egret]

hmm

[lofty rapids]

click pick hit testable widgets

and hover over the viewport while your playing, and click see what it shows

[naive egret]

ok

[lofty rapids]

you should just be abble to hover

and if your not getting blocked it will be the viewport

but if a widget is blocking it it should show that

for instance if you just started a new project, show mouse cursor, and enable click events

the on clicked should work, pretty much thats all you need

[naive egret]

Wokay Imma check that out

is line trace better?

[lofty rapids]

i mean you could perhaps do a line trace on click, but i don't think it's "better"
imo this would be just hiding a problem instead of fixing it

but it could be a possible work around

it's easier to implement the onclick on each one, then line tracing, and calling an interface function

i would take a look at what the widget reflector says

if it says your viewport isn't the one getting input, and shows a widget then thats your issue

[crimson arch]

hello . I'm new on this server. Can someone please help with my blueprint? I don't see the problem , but when the zombie comes near me , it stands for like 5-10 seconds and then attacks me, but I want it to attack me instantly. here's my blueprint if someone knows please respond

[naive egret]

so when I clicked on the screen this is what the reflector says

does that mean the viewport is getting the input?

[lofty rapids]

ya i think it's not a widget, wild

[lofty rapids]

in the attack player event, right at the start put a print string, is that delayed as well ?

[lofty rapids]

thats the same mine says everything should be ok

hmm

[crimson arch]

wait a sec imma try it

[snow halo]

Hi I have a question. I have a widget made for my main menu. Im pressing the Play button, but nothing happens, not even the play event works, it's as if the click input doesnt go anywhere. 🖱️😞

[crimson arch]

yes , its delayed as well idk why tho

[snow halo]

I have also an event dispatcher that will unfreeze the game and will turn it to normal speed where's when you're in the menu selection it's time is frozen ⏲️ 🥶 🧊

[lofty rapids]

does the event fire ?

[snow halo]

no

[lofty rapids]

what is this doing? your creating a main, then looping over all main, and adding a main ?

[snow halo]

oh you're right

I totally didnt pay much attention to that

[naive egret]

I gotta dip for now Imma continue searching about this tmmr thanks for the help !!

[snow halo]

now it looks like this

[lofty rapids]

make sure this is set in your project settings as well

[lofty rapids]

what is the visibility on the vertical box ?

[snow halo]

oh I think there's the problem, thanks

[lofty rapids]

well why is the tatrget actor your player controller ?

[lofty rapids]

well thats what you want i think

self only

so it doesn't effect the children

[snow halo]

still doesnt work 😅

[lofty rapids]

whats the visibility of the button ?

[snow halo]

I tried visible

same result

[lofty rapids]

it should of been visible

hmm

does the quitt button work ?

[snow halo]

it doesnt

[crimson arch]

I didnt even notice that lol

[snow halo]

I've added this {self} here

but no change

I've set global time dilation to 0.1 instead of 0, still doesn't work

I think this problem might be related to having the widget blueprint on the level blueprint

any time that I've created widgets inside of actors they worked

only now im creating a widget from a level blueprint for the first time & it doesnt work

and i have many widgets in my world and I never had this problem

But I need to have this code inside of level blueprint, although I can also have this code inside of controller

because im using the same game state, im not switching around any levels or anything, im in the same island level both in menu & after I press play

[crimson arch]

yooo thank you bro I fixed it thank you so much man

[lofty rapids]

mamybe #umg might know more about it ?

[lunar sleet]

So don’t use level bp. You cannot communicate with it, it is pre-Kismet 2.0

[lunar sleet]

I very much doubt you need to have it in the level bp

[snow halo]

I can with event dispatchers

[lunar sleet]

Oh, does it work? Cause it sounded like it wasn’t working

[snow halo]

only for these

not for this one

im also using these now but still doesnt work

inside of the widget

[snow halo]

it doesnt work because of the click events not working

but the dispatchers can work, im curious where could I put these instead of the level blueprint? Is there a better blueprint to house them?

[lunar sleet]

Yeah, I’d say do your best to avoid level bp. If need be you can always set different player controllers or just use one and have a check that does diff things depending on the level

But to answer your question player controller or game mode or even game instance would prly be ideal

Depending on your approach

[snow halo]

game instance is a blueprint?

[lunar sleet]

Yes

[snow halo]

which of these is the game instance?

[lunar sleet]

You have to create a GI bp parented to Game Instance, same as you would for your PC or GM

[lunar sleet]

It’s not there because it persists across all levels

Hence why I said it depends on your approach

[snow halo]

oh I was going to do this anyways after I created a main menu , because I needed to do that anyways for my saving system, but I thought I can't have a saving system before a main menu first 😅

[narrow sentinel]

if theres anyone in this channel that knows how to do control rig stuff at all would love some help over in that channel, having a bit of a mare with it

[snow halo]

I assume Init in gameInstance is the same as begin play?

[lunar sleet]

Not quite, I think it happens earlier

I think it should have its own begin play but I can’t rmbr

[lofty rapids]

i don't think it has begin play

just init

[lunar sleet]

Oh maybe then. I wouldn’t assume it replaces begin play tho, GI init could be occurring way before anything else, but you can always test it

[snow halo]

im doing something like this

mouse button events still dont work, seems its not related

[lofty rapids]

did you check the widget reflector ? something i learned about the other day

it will tell you if something is blocking

it will tell you when you hover over the button what is currently consuming input

[lunar sleet]

When it comes to widgets sometimes there’s things on top that can cover the area where you’re trying to get a click response from

[lofty rapids]

do you set game mode anywhere ?

[lunar sleet]

You mean set input mode?

[lofty rapids]

yes, mb

do you have game only ?

[snow halo]

I have UI only

[lofty rapids]

interesting

[snow halo]

Though I think it's kinda weird how I have it right now

so it first goes to game instance from level blueprint, and then from level blueprint to widget and then back to game instance like a ping-pong with this dispatcher here 🏓🎾

[lofty rapids]

when you hover over the button, do you notice any change or nothing happens ?

[snow halo]

But the problem is, if im going to make a modular menu with more functionality then this isn't really gonna be very modular

[snow halo]

nope

[lofty rapids]

ok so create a blank widget, throw a canvas on it, throw a button it

see if that reacts to your clicks

[robust belfry]

Need help plsss

#animation message

[snow halo]

btw this widget reflector thing doesn't show me any widget elements at all

[lofty rapids]

idk much about it, i just heard about it the other day

[lofty rapids]

did you try another widget, see if that one recieves the input ?

[lofty rapids]

you clicked pick hit testable ?

[snow halo]

yes and yes

for example here's crafting menu

[lofty rapids]

ok so it's working with other widgets

[snow halo]

also I just realized canvas has this collision

[lofty rapids]

not hit testable (self only) iss what you want

this should click through

[snow halo]

ill try to remake the widget

[lofty rapids]

also

try to remove from parent

the add to viewport

again later on

to see if something is over it

[snow halo]

there are many widgets on my screen 😂

but they are not visible

[lofty rapids]

iff you remove then add it will bring it to the top

so do that on button click or a keyy press

just to see if thahts the issue

[snow halo]

yes

somehow when I do that

for example

i click on a chest

it opens up a widget

then it works ➡️ ✅

or when I open up my crafting menu or any other menu

very strange

[lofty rapids]

when you are displaying it are you just changing visibility ?

[lofty rapids]

can show what happens if you hover over the widget that doesn't work ?

does it not do anything ?

show what the widget reflector shows when you hover over the button

[lofty rapids]

when do you run this event ?

[snow halo]

So when I do that it thinks im hitting the player damage effect "blood widget" shows up infront of it

I just wish there was a way to set a priority on the widgets

[lofty rapids]

when you add to viewport you can set zorder

so you can set which ones go over what

click on the arrow down on the add to viewport

and enter a high number for thatt one

if you want it always on top

[sharp ferry]

Hi, how can i make the Followcamer not going out the view but having collision with walls?

[lofty rapids]

is the camera on your character ?

[sharp ferry]

yes

[lofty rapids]

do you have a spring arm ?

[sharp ferry]

it goes out

[sharp ferry]

sorry i dont know what it is

[lofty rapids]

it's what you need most likely... you want when the camera is too far through a wall that it moves in so you always see your character ?

[lofty rapids]

it's a thing that you attach the camera too, and it has blocking built in

[sharp ferry]

i want that the camera respect the wall collisions, it needs to stay inside the room not see outside like there

the camera is behind

should i change some options to respect the wall collision when i move the visual?

[lofty rapids]

well you can do a line trace and move the camera, but a spring arm does this automatically

[lofty rapids]

add a spring arm, then drag the camera into the spring arm

[sharp ferry]

is it simple to do?

[lofty rapids]

ya in the components in the top left just add, spring arm

[sharp ferry]

where are components sry

[lofty rapids]

hold on click camera boom

i think thats your spring arm

[sharp ferry]

i added the srping arm yea

its below Folowcamera now

[lofty rapids]

delete that because i think you already have one

[sharp ferry]

yea i have a camera boom

[lofty rapids]

in this picture, click on camera boom, i think thats your spring arm

[sharp ferry]

yes

[lofty rapids]

click on that, in the details on the right

check do collision test

is it checkedd off ?

[sharp ferry]

is alreayd on

on*

[lofty rapids]

hmm

and what is says for probe channel ?

[sharp ferry]

''camera''

[lofty rapids]

whats the collision on the walls n stuff ?

is it block camera ?

[sharp ferry]

mh need to check

[sharp ferry]

is block all

[snow halo]

I'll try this to be sure 😁

[lofty rapids]

hmm, i wonder because the spring arm is supposed to do what your talking about

[snow halo]

it works ✅ z.order works 💡

[lofty rapids]

i actually noticed it the other day

[lofty rapids]

click onno the camera boom and show me the whole red line

maybe your camera is offset

it doesn't seem like it in the picture it's just a bit off zero

[steady night]

hi i got this "lava" material but its like draining all the light making the room super dark

how do i turn that off ?

[lofty rapids]

you want the material not to glow like that ?

you can probably turn it down or off completely

[steady night]

yeah

[lofty rapids]

show the material

hopefully it's not too complicated, but there is #materials if so

[steady night]

https://blueprintue.com/blueprint/byca7_b5/

im thinking it could have with blend mode or shading model to do or ?

[snow halo]

Another question, I have a swimming post-process inside of my character blueprint.

Im trying to make a sequence video start on begin play. Like this video:
https://youtu.be/-b9FO8iQYSY

he deletes this Player Start Object, and adds in his FirstPersonCharacter object. But if I do this then before I start the game I'll have this post-process always in my face.

Although when I press play it goes away, I still want to understand why that happens. This post process...

My prost process on Character Begin Play is automatically set to disabled by default. It only enables when I enter the water 🌊 🏊‍♂️

I remove the character blueprint, and use the Player Start, it all works ✅

[lofty rapids]

first thing make a copy in case it fks up, but what you want to do is plug where it's going to emissive color, instead take that output and plug it in to just base color

emissive color is whats doing that i think

[steady night]

yeah that was simple

however the emissiv stuff makes it glow obviously

[lofty rapids]

are you using an instance of the material ?

or the material itself

[steady night]

yeah

inst

[lofty rapids]

ok so theres probably a setting

possibly whatever this parameter is

for how much it glows maybe ?

or there should be propertys anyway hopefully with good names

[steady night]

yeah well it multiplies by 1,0 if i reduce to 0.2

wait ill show u

[lofty rapids]

did you change the instance or the material ?

change the property in the instance

[steady night]

im using the main one now

1: 0.2 2: 1.0

is as "base color" instead of emissive

[lofty rapids]

ya thehre should be in the instance settings as parameters for this kind of thing

like brirghtness

[steady night]

i like the one where its glowning the 1.0 but its so dark on the platform

i made the material myelf, (tutorial)

[lofty rapids]

change the color to a darker green maybe ?

so it won't be as bright

[steady night]

yeah that helpd abit but the reflection i awfull

[lofty rapids]

i can't help much more with materials, something i have just done a little not much with

[snow halo]

I fixed it

✅

[lofty rapids]

you should always have a player start

thats the goto for the beginning of the game

[steady night]

hm alright ty , ill check with material

or i changed it to "unlit" hading modelk

much better

[snow halo]

but I need to use player character blueprint instead

[steady night]

perfect *

[lofty rapids]

wdym ?

[snow halo]

player start is an object

but player start is not the same as character bp

https://youtu.be/-b9FO8iQYSY

he uses his character bp, not the player start element

[onyx token]

is there a smarter way to do this?

to make 08 instead of 8

this seems really dumb.

[onyx token]

oh god

[sharp ferry]

sorry i was eating

[onyx token]

oh that does do it, thank you!

[lofty rapids]

click on your camera

set it the location to 0,0,0

yourcamera should be at the end of the red line

if you want to move your camera, rotate the spring arm

if you want it to go farther back use target arm length

[sharp ferry]

fixed thanks

i've learned also what is the spring arm too

[uneven crest]

Trying to get the end point of where my mouse is clicking but the logic isnt working

is something off with my code

it doesnt go where i clicked

[lofty rapids]

so you wwant to click stuff with a trace ?

[uneven crest]

i want to spawn a actor from a certain point, and have it end where the mouse click is in the world

[lucid stream]

I have a user widget that contains another user widget. My upper layer is ticked but the contained widget is not. Is that normal? Are we expected to manually tick containing widgets?

[lofty rapids]

i'm not sure i understand, you want it to start somewhere and end another place ? your current logic i'm not understand what is world direction supposed to do in this cases that you have ?

[surreal peak]

The inner Widget should also tick if you add the event

[lucid stream]

Oh silly me I just wasn't called the parent class tick

Ty!

[uneven crest]

Basically im just trying to set a line trace to end where my mouse click is so that I can get that location

Nevermind got it to work

[lofty rapids]

what did you do ?

[uneven crest]

In the addition part, i put the world location into the top instead of the direction

[pastel garnet]

anybody need an object pooling solution? I created one and looking to get feedback on actual use cases for it and the performance benefits
https://github.com/Lazy-Jason/LazyGenericDynamicObjectPool.git

im trying to improve my skills in unreal and get myself ready for industry level optimisation consideration 🤧 this is just start

[snow halo]

Hi, I have a problem 🎮 🪲 🦠

So when I start my game. I have an camera sequence playing 📽️ the camera is floating around etc etc.

and the main menu shows up on the screen 📺 💻 🖥️

while the screen is moving around

this all happens on begin play! ▶️

but as soon as I begin play there is going to be a character getting created. How does that happen? I dont want a character to be created by begin play

I wanna try to create & spawn it through blueprint manually 🪄 ✨

[lofty rapids]

are you saying as soon as you load the level it possesses a character ?

[snow halo]

yes

[lofty rapids]

in your game mode override
select none as default pawn

[snow halo]

and I have both Player Start element as well as the character blueprint deleted from the level

[lofty rapids]

its probably your override in world settings, it's got a default pawn in it

[snow halo]

yes but that only happens on (PIE) not on selected viewport

https://tenor.com/view/apple-pie-dessert-pie-food-gif-11076903047904035201

(I just noticed this)

[lofty rapids]

it happens in selected vieport i'm pretty sure

[snow halo]

should I remove the default pawn?

[lofty rapids]

ya thats whats happening, the level is loading from the override

[snow halo]

This is why I wanna destroy the player character

[snow halo]

sometimes for example I get spawned in the middle of the ocean way way out of the map something like 0,0,0

🤔

[lofty rapids]

you want a player start for sure

but don't have the override load the pawn

[snow halo]

But this will still create these character widget elements on the screen 💻 🖥️📲

[lofty rapids]

if you don't want the pawn to load then thats how, but if the widgets are still on the screen then the pawnn doesn't add them to viewport it's probably happening somewhere else

[sharp ferry]

i-ve followed step by step a tutorial to grab and object with E and drop it holding t, i setted all the nodes like he did but hes in first person im in third, he use the Fir person camera as first node, what should i use_

[lofty rapids]

first node ? wdym ?

are you talking about the trace ?

[lunar sleet]

Show a proper screenshot of the nodes

[sharp ferry]

yes

[snow halo]

it's probably happening somewhere else

but when that happens the Character is created

[lofty rapids]

oh then it could be the character, is there one in the outliner before you press play ?

[snow halo]

nope

[sharp ferry]

i did that on my main character BP

[lofty rapids]

is your line trace not hitting or going straight ?

[lofty rapids]

you don't want to multiply, try a add instead on that trace

[sharp ferry]

the blue one_

the blu node?

i understand nothing of that i just copied his nodes and did exactly the same so is so difficulty to understand how to add instead of multiply

i guess the multiple are the two yellows nodes

[lofty rapids]

see this is multiply, it's usually add

but draw the trace

draw debug type

select persistent

then when you press the key you'll see the trace

to see if it's going straight and far enough

[sharp ferry]

i

added the +

instad of multply

i cant pick up the two objects

i dont understand what should i add instead of first person camera

bc i dont have first prson camera

im third person

so i added the capsule that

there*

[lofty rapids]

ya the capsule should be fine

read what i wrote above

draw debug type

you can track what is going on with this trace

atleast see if that is working

[sharp ferry]

how do i active that?

i started unrealengine today

[lofty rapids]

on the trace by channel node

[lofty rapids]

ok so its hard to help this early for me because you won't know what i'm saying to you

[sharp ferry]

yea indeed

its weird i followed the tutorial step by step node by node

i know about the trace that lights up meaning its working

if u mean the dynamic connection smooth

[sharp ferry]

whats the first thing i can do easy as BP? this is already too complex i dont understand a single node here

id like to understand what im adding and doing

to be self-sufficient later

i will try another tutorial in Third person same grab and drop

[lofty rapids]

lookup blueprint beginners tutorial specifically

it will do more to help with thhe nodes

[sharp ferry]

when i look at these tutorials i just wonder how they can understand what to do all the time is soo difficutl

[lofty rapids]

likee how the nodes work, what variables are, functionns, stuff like that

[sharp ferry]

yea indeed i dont even know whats a function or variable

[lofty rapids]

https://www.youtube.com/watch?v=aw-GMag53h0

https://www.youtube.com/watch?v=6D38CWw7VgA

[lofty rapids]

this is stuff you'll have to look into, its fundamental programming stuff

[sharp ferry]

thanks im gonna save the videos

[glossy fern]

Hey guys, I have a small questions, if I have a character blueprint X , with a component Y , the component Y is implementing an interface Z, if I call a function from that interface from another blueprint outside of this scope, does the call work on the character X or is it ignored ?

[faint pasture]

Do you mean, if you call Character.Zfunction, will it do anything? No, the character does not implement the interface, the component does.

What component and interface is this?

You can probably get rid of the interface

[glossy fern]

I meant like a projectile hits a character X, character X has component Y (custom BPC), component Y is implementing interface Z.

• a projectile K hits character X , and calls a function from the interface Z , does that call go through or not?

if its too unclear please tell me 😅

[faint pasture]

makes the Z interface call on WHAT OBJECT?

Does the projectile call Character.Z or Character.ComponentY.Z?

[glossy fern]

I am trying to avoid doing that, trying to avoid hard calls and casting

so no, it does a call on the hit object

[faint pasture]

Character does not implement Z so no it won't do anything

Is this health and damage?

[glossy fern]

which is the character X, but the projectile doesnt cast or anything it just calls the interface function with the hit object as a target

[faint pasture]

that casts under the hood

but casting is fine

to base classes that are commonly used its basically free

[glossy fern]

i think so, I had a small Idea Im trying to implement

yeah just like health and damage

[faint pasture]

I'd just keep the component energy going though, doing damage to something can just be "Get component by class HPComponent, call HPComponent.TakeDamage if it exists"

you can think of a component as an interface + state

[glossy fern]

ahaaaaa nice !!

[glossy fern]

ill check it out !

[uneven crest]

Anybody know why its not firing the projectile

it spawns the acotr

actor

but doesnt shoot

projectile movement is added to the class

Nevermind got it

[lofty rapids]

i'm guessing you were missing initial speed ?

[sharp ferry]

i almost comploted the tutorial but im stucked in one place, about the third person grab an object holding it with mouse left. so the problme is, he used ABP_mANNY and have different nodes like this but on my character i can't connect that grey node to add a pin and procede with the tutorial

in this phase im trying to add ( i think) the carrying animation of the box

[uneven crest]

had inital speed. on the sphere i had simulate physics

[lofty rapids]

so whats the problem the warning ?

[sharp ferry]

I have different layouts than Manny, i don't know how can I connect the grey node to create a new pin on my character

i was litearlly to the end of the tutorial

[lofty rapids]

i don't know what this means

"create a new pin" ?

are you still not sure what the white lines do ?

[sharp ferry]

i was just trying to finish this tutorial to grab and hold/move an object customizing a idle animation and split it half bones with Run animation too

holding my BP box

[sharp ferry]

i dont know how to connect that in my Nodes layout, is differnet than manny

[faint pasture]

Do you know what any of this code does?

[sharp ferry]

i don't

but i just would like to try to complete the turoail and add this function to my ''game''

[faint pasture]

Then slow down and figure out what it is you're actually doing

[sharp ferry]

thats true

but i was to the end i would've liked to add this anyway

[faint pasture]

This is just a sequence node, it's just there for convenience

A -> Sequence -> B
-> C
-> D
-> E

is exactly the same thing as:

A -> B -> C -> D -> E

[sharp ferry]

what is that for? to connect what?

i think i need to keep on the tutorial with that thing to connect my Idle carrying animation as a new pin

[sharp ferry]

How can i connect that in my case

[faint pasture]

Why do you need a sequence though

it's the same as just adding stuff to the end of your execution

you really need to back up and just do something super simple, make an actor that does something super simple on begin play, like:

Begin Play -> delay -> do something -> delay -> do something else

[sharp ferry]

im holding the box, and now proceding with tutorial i need to add the idle with the splitted Idle carrying and walking animation

[sharp ferry]

gonna try this ty

i dont get why in the left panel of ''MY BP'' he has ''character'' and i dont

below Reference, i do not have ''character''

[faint pasture]

You have Nadine

you really need to just get the basics

you're flying blind here

[sharp ferry]

if onyl moving a box is just so difficult, what can i start with?

[sharp ferry]

yea nadine is my character but i dont see the same as him in tutorial 😐

[faint pasture]

Start with something super small, and do it without a tutorial

make a door that opens when the player gets near it

[sharp ferry]

i will start to watch the two tutorials that engage snet me

[faint pasture]

make a platform that moves up and down forever

[sharp ferry]

so carrying a box and holding dropping is taht hard?

[faint pasture]

It's easy, but you don't even know what execution pins do right now

[sharp ferry]

even to make my character move with WASD i understood nothing followed the tutorial but did it

yea is wrong i know

but probably the door is gonna be complex as well

[faint pasture]

Make an actor that does something super simple, and do it without a tutorial

it's not complex at all

[sharp ferry]

i cant

i understand nothing of this nodes

[faint pasture]

Then go back all the way to the beginning

[sharp ferry]

the only nodes i use are blender PBR

and some compositing rneder

render

[faint pasture]

Do you understand basic programming?

the concept of a function, a variable, a class?

[sharp ferry]

nope

i thought bluprint was easiest

than coding like unity

or idk

well with time i willl learn some new stuff

today i've learned a bit the layot, import materials, assets and others basic stuff

collisions, camera settings etc

i have in program to make a game where my Nadine cook drugs in this garage and i will also change her clothing

[faint pasture]

https://pll.harvard.edu/course/cs50-introduction-computer-science

Blueprint is easy but it's still programming, you still need to know the concepts

[sharp ferry]

indeed

[sharp ferry]

im italian sometimes even all the infos in english are harder

[sharp ferry]

whats is this?

[faint pasture]

free computer science course from Harvard

Very very good for getting the basics

[sharp ferry]

i think i need something in my mother language for stuff like that

[uneven crest]

I have a projectile sphere that when it lands, just goes through the level. I have bounce ticked on the projectile movement. what else do i need to tick?

[lunar sleet]

Collision

[uneven crest]

i added a collision but it still doesnt do anything

[karmic sinew]

is there any way to keep a player moving in a direction without input, and be able to direct themselves while doing so?

i've tried fiddling around with the character movement parameters and nothing worked, so i came up with a roundabout method with a counting script (pictured here), but is there any way to do it without it?

player rotates using AddActorWorldRotation, and these are operated by button presses so it all starts off EventTick

[snow halo]

Hi I have a question about a struct im making.

https://youtu.be/H6rqJbwjRIk?t=330

Im on to this video, (timestamped already)

my question is... I have a world with many many actors

some of these actors are manipulated

like you pick up a fruit

that fruit never grows back

or you break down a plant or you create a farm somewhere

aka you plow the dirt (it creates a plow dirt blueprint somewhere in that level) but now think of this... I have many types of items and probably a lot of these items are gonna be placed at maaaany many areas around the map

so my guess is, load and save could get a bit expensive or heavy, this can be kind of complicated

this is the player struct I have so far.

However, I've made it so that trees grow back after 50 seconds so now I dont have to save anything regarding trees

but the farming system will probably get really complicated

[steady thicket]

Hi! I’m currently working on a third-person movement system using Enhanced Input, and I want the player’s movement to be relative to the camera’s rotation and position. Basically, when the player presses W, the character should move forward in the direction the camera is facing, and A/D should strafe left and right accordingly. However, right now the movement is completely off — pressing W moves the character to the left, S moves right, A moves down, and D moves up. I'm using the camera’s world rotation and then getting the forward and right vectors, which I plug into Add Movement Input. But I think I may have wired the input values (X and Y) incorrectly or misunderstood how to apply the camera's rotation. Could someone clarify the correct way to use the forward and right vector from the camera for this type of movement? Should I ignore the camera's pitch or swap the X and Y input axes?

[uneven crest]

Is there a way to get the closest actor to a certain location?

[faint pasture]

just start checking

What's the use case

I'd probably do some traces instead of iterating over every actor in the world

[crimson arch]

DId you check that the input actions are right?

[full badge]

try 'get closest actor' node

[burnt citrus]

uhm, if i have a function that end with a loop, do i need to use a return node on the "completed" output of the loop?

i mean if i need to add a different function or other stuff on the same exec line

i'm worried to add stuff after the function and they are still looping

[visual ember]

the loop runs inside the function and continues through the Completed exec pin on the loop node. if you have nothing after that, then the function just exits

[burnt citrus]

ok thanks, so when i attach another function after the first function is not looping

i suspected that but i wanted to be sure 😄

[visual ember]

the next one in line won't loop

functions are "scopes". so whatever happens in the scope, stays in the scope, so to speak. once you exit (return) the function is no more, so is the loop inside of it

[burnt citrus]

so if i attach a return node to the looping part inside a function, the next function won't loop either?

[visual ember]

what do you think?

[burnt citrus]

i think it will not loop :p

[visual ember]

and why is that?

[burnt citrus]

cuase you said function are scopes? 😄

[visual ember]

and what follows from that? 😄

[burnt citrus]

btw i can just attach a print string after a function to see :p

i was just asking to be really sure

[visual ember]

and I just suggest to "think it through" quickly first. should help with understanding 🙂

and then test to confirm your prediction

(but yes, once the return is called, the function stops the execution, including the loop)

[burnt citrus]

so basically return nodes are used only for output variables

[visual ember]

no. you can return at any point, say based on a condition. like in your loop, you can have a branch to check a value and put a return node there. so the loop will end and the function will exit

[burnt citrus]

ah, nice

[visual ember]

other than that return nodes are somewhat optional

cause the function will return automatically once it has nothing else to call (execute) next

it's advised to put return nodes explicitly though, so the intent is clear

[lime crow]

anyone know where the show fps button has gone in 5.6?

[lime crow]

Legend, thank you

[remote shore]

i have some issue trying to send information between 2 blueprint. The Item BP has the item information and on event i want the information to go to my component BP_Inventory. BP_Inventory is also inside my player controller

[lofty rapids]

is the print string showing up ?

[remote shore]

defn not, because like said above it is inside a component in the player so i can't set a reference on scene. Give a error on accessing something empty

[lofty rapids]

ok so you set the reference type, but it's not actually set

this node might be what your after

[lofty rapids]

^i think this node will work

set the target to be the playercontroller reference

or just get player controller and use that if it's the active one which i bet it is

and then use that as target, then get component of class, bp_inventory

then drag out from that and run the event

[remote shore]

wherre i put that?

[lofty rapids]

accessed none, this is a typical mistake i see a lot, the variable has a type set but this does not actually set the reference

you need to actually set the variables value after you assign a type

[lofty rapids]

you know anything about getting references ?

[remote shore]

50/50

[lofty rapids]

you see where you have the item plugged into the event call in bp item

you can replace that item with get player controller -> get component of class

then when you drag out, you should be able to call the event

oops you started a thread mb

[granite nacelle]

can someone please help me with this. My skull pawn moves weird when moving to patrol points, I wanna know what could be causing this and how to fix it, the second video is its blueprint

[lofty rapids]

unhook the set rotation, possibly it's rotating and moving forward trying to find the path again

the tick, unhook it just to test

[granite nacelle]

i unhooked the set rotation but it doesn't stop the jagged movement

[lofty rapids]

i have a hard time with videos and bp it's a pain the ass tbh

but can you show what it does without the tick hooked up ?

[granite nacelle]

just tried it and its the same, when it reaches a patrol point it shakes all over the place

tried begin play also

[lofty rapids]

put the tick logic at the end when it hits a spot

so it lands, rotates toward the next, then delay and move again

[lofty rapids]

is there any reason your using move to, and not ai move to ?

[sharp ferry]

to add a Posterize effect to my render, i have to do with a material?

or is it possible to do with BP on the whole scene?

[granite nacelle]

so I set the skulls collision to overlap with pawn only and it seems to be working now, it seems that the collision was colliding with something or everything

[lofty rapids]

oh nice

collision can be a pain, it needs to be seet just right

[granite nacelle]

I already set it once so I didn't use it again

[granite nacelle]

yeah thanks for the help though

[lofty rapids]

i just can do debug stuff, could be this, could be that

i'm still learning myself

[lofty rapids]

its a lot easier to help (for me atleast idk about anyone else), if show images or use : https://blueprintue.com/

videos are a pain tbh, you have to pause and click through to get views on what is going on it's hard to track imo

videos are good for showing the problem not the code i think

[void pewter]

hi guys i just need help what's the material function. I really confused about this. I don't get it clearly

[lofty rapids]

wdym " material function " ?

are you asking what is a material used for ?

[void pewter]

i mean What are material functions used for?

[lofty rapids]

#materials know all about this stuff, but i thinks it's basically a function set for materials that you can use, never used one before myself

[void pewter]

thy

[lofty rapids]

"Encapsulates complex logic into a single, easy-to-use node that can be shared between materials"

[lime yoke]

I'm curious about these situations. I know using cast is mostly bad with some exceptions and if possible using interfaces are the best option, but between these two type of events, which is "better"? I'm using Character as an example but I'd replace that with my own PlayerCharacter class with has much more features and components (which may require more memory usage?)

[zealous moth]

@void pewter let's say you need to sample all 9 directions of a single pixel. You can either copy paste the same thing 8 more times or make it a function and have a different input.

[lofty rapids]

i mean before you launch player on the top one, theres a cast just further down the line correct ? or am i missing something ?

[zealous moth]

@lime yoke using cast isn't bad. Having several hard references in a container or using non-specific casts can be bad but most of the time aren't.
Interfaces are used for messages in a sense that if it has that interface, then it will see it so you don't need to cast to 100 objects at once.
To answer your question, you can use get player character and launch that instead of casting.
