blueprint

[lofty rapids]

but you can use a timer it will work the same

[faint pasture]

the problem is your code is a mess

tick is the correct place to put movement

[frigid summit]

it didnt

[lofty rapids]

hmm

not understanding what the code is doing makes things a lot tougher

[faint pasture]

Event GetOn -> set CharacterRef = CharacterThat'sGettingOn
Event GetOff -> set CharacterRef = Nothing
Tick -> if CharacterRef.IsValid -> figure out where CharacterRef is on the spline -> add to it based on delta time and speed variable, move CharacterRef to the new place on the spline -> If at the end, call Event GetOff

In plain english it works like "If theres a character we care about, move it along the spline. If it reached the end, we don't care about it any more"

[lofty rapids]

i would look at some blueprint tutorials that teach some basics

especially if you never programmed before

[frigid summit]

man im 2 years into the game i developed 4 games

[lofty rapids]

interesting

[frigid summit]

but i still messing the basics

[lofty rapids]

ya programming and game dev do have a lot of differences

[faint pasture]

ignore the animation, ignore rotation for now, get it to slide to the end and get off or whatever you want to happen at the end

[frigid summit]

ok ill try this

[dry coral]

Hi yall can i ask a question in here mid conversation about a blueprint script not presenting itself?

[lofty rapids]

"presenting" ?

[dry coral]

So I have this cyberpunk pack from a long time ago Im using for a project
I used the objects in the actor folder below

But whenever I put the actor into the world, nothing shows up

[lofty rapids]

anything in the outliner ?

is that the object in the outliner ?

do you have visible checked ?

[dry coral]

Im sorry a bit of a novice, is the outliner the details?

[lofty rapids]

well i see in the outliner your selected the thing you dragged in i think

but the outliner has all the stuff in the scene in it

so when you drag something in, it will be in the outliner

[dry coral]

Gotcha

[lofty rapids]

but what does the actual bp look like ?

if you double click it

[dry coral]

THis is the blueprint

[lofty rapids]

click on viewport

[queen valley]

he prob meant you should show the viewport

[queen valley]

beat me to it

[dry coral]

like this?

[frigid summit]

still

[queen valley]

no no, go into here and click on "viewport"

look at what image i replied to

[lofty rapids]

it's a tab your current in event graph

[dry coral]

Sorry if I being to much

Where is "here"

Oh wait

in the blueprint

[queen valley]

yea

[queen valley]

no dont be sorry for trying to learn

[queen valley]

uhhh you see, there it shows nothing thats why it is invisible

when you place it

[dry coral]

Sorry I get so scared im just being a dumb butt around 3d art channels, I had a bad time in a blender one lol

[queen valley]

i got ignored many times too lol

[dry coral]

Hmm, is it something in my folder importing thats wrong, should i reimport it ?

I dont know blueprints

[queen valley]

look at the static mesh'es transform

no dont think

[queen valley]

@lofty rapids you have any idea? (sorry for ping but I have no idea other than wrong transform and visibility)

[dry coral]

nothing in the meshes

[lofty rapids]

looks weird like a bug because the viewport should atleast be there

[dry coral]

Let me slot them in

[lofty rapids]

there it is

atleast its on the screen

[queen valley]

uhhhhhhhhhhh

look at the LOCATION

dayyymmmmmmmmmm

[dry coral]

well it is a cyberpunk pack

maybe it builds the building

[queen valley]

how big is the building

[dry coral]

a skyscraper

so looks like i gottta do it bit by bit

and rebuild

[queen valley]

but it shouldnt be location since its imported and not changed right?

[lofty rapids]

try zooming out

how big is big ?

[queen valley]

yea he may be in the mesh

[dry coral]

I dont know myself

[lofty rapids]

after you place it it, zoom way out see if you see it

and your meshes might be just huge and your inside them so you can't see them in viewport

[queen valley]

i would laugh so hard if thats the case

[dry coral]

All the way up there

and un textured

welp imma have to rebuild bit by bit

[queen valley]

yep his location is wrong i think

[queen valley]

how did you import it, from where

[lofty rapids]

your origin is probably off

fbx ?

[dry coral]

Well the object is not the building, its the airconditon on topp

[queen valley]

if he messed with it in blender he may have moved it somewhere also blender and unreal x y z are different

[queen valley]

no i meant where you got the model

did you export it from blender

[lofty rapids]

what does self look like ?

if you don't see anything then click on the component and check it's location

you may have them way off center

[dry coral]

Not It was a cyberpunk pack i got online

What sucks about it is that i used this for another project and everything worked

this being about a year ago

maybe 2

[lofty rapids]

i would re import if you can

but it might not help anything

it could be a compatability thing what version it comming from ?

a couple years probably an older version ?

are you still using that version ?

[dry coral]

Gonna try that

Now i imported the folder by putting it in the content folder from the internet explorer

you think there is a different way

or not

[lofty rapids]

i have not migrated anything yet so idk the any way aside from best

[queen valley]

afterall he can rebuild it in the actor bp with the static meshes he has

[lofty rapids]

its a bit weird it looks fine in the preview

[dry coral]

Im gonna try to reimport

thank you so uch for all your help!!

[hidden cedar]

anyone have any tips on making very dynamic movement like in Dusk or Ultrakill? Is it mostly the camera that gives that super smooth and dynamic effect?

[lofty rapids]

i also wouldn't play montage on tick

just set your animation to running

or set up a state in the anim bp that you can switch on and off

i would still use a blendspace

[faint pasture]

Ultrakill just looks like old school shooter movement

[warped juniper]

Yeah I feel it has straight up consistent gravity as well

Just that there are a lot of instances where the player Z velocity gets adjusted / changed

For instance doing a slam is like Mario. Your Z velocity is fixed downwards

[faint pasture]

You can do all that with the CMC

[obtuse glacier]

Hey there, does anyone know how to toggle next AI character when debugging state machine on PIE? I’d like to use a keyboard shortcut rather than switching windows for selection if possible

[gusty shuttle]

Off the top of anyone's head

How does one join a spline end point and start point together? I know with splines in landscapes it's Ctrl, but for a regular spline actor, is it possible and if so, how?

For those who are wondering, you just have to go to the spline component and enable "Loop"

[zealous moth]

and if you wanna make it a semi-perfect circle, use bezier

[gusty shuttle]

Thanks for the tip!

[zenith knoll]

any idea on how to optimise settings the variable on tick?

is a gate more optimised? or 2 branches instead? or is this as good as it gets

[lunar sleet]

Are you having perf issues and profiling is telling you that this is not optimized?

[zenith knoll]

non it just seems wrong to set a bool on tick, optimisation happens on every step of the production

[lunar sleet]

Premature optimization is just as bad as not doing it

Build. Test. Optimize what needs to be optimized. This is the way.

[wise ravine]

Hey does anyone have any recommendations for videos to watch after this one? (https://youtu.be/EM_HYqQdToE?si=4x_au9oMaaUHKnSV)

[light garnet]

I have a major issue

Whenever i restart my project. 1 errors that compiler issue

When i refresh node. It's fine

Then i save the project and restart. Same issue

This is an engine bug ??

[lunar sleet]

The next thing you should do is start building stuff

[lunar sleet]

Maybe, or bp corruption

[light garnet]

Bp

Widget blueprint

Only 2 node

For each loop and create widget

[lunar sleet]

Recreate the bp

See if it still happens

[light garnet]

So many things in the widget blueprint

[lunar sleet]

Then restore from source control to a point where it wasn’t broken

[light garnet]

I did

I added backup

When I extract my backup it's same

@lunar sleet ..

[lunar sleet]

Show screenshots of what’s happening with win shift S

[light garnet]

I am reinstall engine version

I will send you screenshot when it's done

[vestal acorn]

Working in VR tracking hand position, want to move objects based on my handmovement, but only in one direction at a time

Tracking the velocity of the hand works, but not quite sure how to properly detect which of the 6 Directions/Axis is currently the highest value, trying some complicated min/mac branch comparing but its very stuttering https://blueprintue.com/blueprint/8fqaqsoa/

[frigid summit]

yea i tried this and still

[frigid summit]

the only thing left for me is i find alternative to splines to make the charcter move on the track

[hoary kraken]

how can i make a chicken ai for my game

[light garnet]

Still same issue

See after reference node i have the same problem

[dawn gazelle]

Try disconnecting these pins. Recompile. Save. Close out your project. Open it again. Connect the pins back up. Compile. Save. See if the problem persists.

[light garnet]

bro you dont understand

its compline just by referse

problem is whenever i restart probject. same issue

[dawn gazelle]

I do understand. Structures in blueprints can bug out and the structure type connecting through this foreach loop could potentially be stuck with an old version of the structure. Disconnecting the pins I've indicated and recompiling and saving and closing out while the pins are disconnected could potentially correct it, but you do you.

[lunar sleet]

And also maybe don’t use bp structs

[rain wraith]

Any recommendations for saving (to the SaveGame blueprint) the data of multiple arrays stored inside a class that has multiple spawns of it. I have a system of multiple pawn classes that are spawned on a timer and each pawn's component transforms (multiple components) are stored in multiple arrays inside its BP, so I need to store the existence of the pawn itself as well as the array data inside the pawn for all spawns of the pawn and be able to load the array data back to the components for each corresponding pawn

[gentle urchin]

How often can a direction change? Whats the criteria for direction change ?

Sounds like a very troublesome control, unless its related to "while holding x"

You could then track initial loc on press, and just track current while held, then pick the highest value axis from there

[vestal acorn]

Its exaclty while holding X xD

Think I figured it out mostly

[frigid summit]

i fixed everythig by just using a timeline

[lyric pumice]

I have two Box Collisions on my map and I want to activate only the Box Collision my character is in, but when I use "Get All Actors" and I'm only in one Box, it understands that I'm in both at the same time, using my item twice and confusing everything. How can I make him understand that I am in Box A or B?

[strange grove]

is there an option to get via blue print the lumen/light level of an area?

[dry sleet]

I don't think so, those calculations are potentially quite complicated.

[wise ravine]

Build what exactly?

[ripe loom]

hello guys, i have this dash blueprint right here. its work well but when i jump AND dash or dash And jump, it goes further than just dash alone . how can i make it stay consistent on the ground and in the air. I've tried everything for the past 2 days now

[silver blade]

Would there be any reason why the stop movement node doesn't work?

[pale obsidian]

Dont use addImpulse. Use setVelocity

And set it for a specific period of time, probably similar to length of animation. You could use animation notifies in the dash montage to fine tune disabling/enabling of root motion or IK.

This way you hard lock the distance and speed of your dash

[olive pasture]

how would i get game time from a blueprint object? is there a way i can somehow access the owner or world that an object is in ?

[pale obsidian]

Just be sure to Add some sort of logic once the - is over. So that if you dash, an airborne or dash off of a cliff that increase velocity doesn't continue longer than you intend

[pale obsidian]

Maybe you can use an interface to communicate with the level blueprint

[olive pasture]

thank u

[lofty rapids]

wdym ?

"expand" ? on what array ?

[digital palm]

Hey, I'm trying to understand the difference between these 2. Optimization?

[lofty rapids]

i c your getting the actor and checking a variable ? i'm not understanding the problem

[lofty rapids]

it's probably close to the same math i would guess

distance is distance

[remote meteor]

they are the roughly the same, bp would have a very slight overhead on each node, but if we are talking about optimization,
if you need distance only for an comparison, always use Distance Squared option and square the comparator, cause cpu sucks at squareroot-ing, especially large numbers

[digital palm]

the objective is to compare distance between a lot of objects and probably for long distance. So I will use distance squared instead

[icy plover]

I have a level that is only UI interaction. So in order to keep the camera is a fixed location, I Set the View Target with Blend. The problem is that when I transfer to a different level, no mouse interactions work. How do I undo Set View Target with Blend?

[digital palm]

new set view target with blend, but the New View Target is your pawn

[icy plover]

So I have two UI levels with that Set View Target with Blend. When I move from the first one to the second one, it breaks. But if I start the second one alone, the mouse interactions work fine and the camera stays fixed. How do I fix the camera for those UI levels? Can I do Set View Target with Blend on two different things (the camera and the pawn) in the same level?

[lyric pumice]

i've two box collisions where i want just one of it activated, but because "Get Actor" only one activates and if i use "Get Actors" both activates at the same time, but i already solved it now, destroying the other actor via variable and using "Get Actors"

[icy plover]

Also, Get Player Pawn doesn't let me drag out to Set View Target with Blend

What I mean is I am running into this, for the second UI level, where I need the camera fixed and I need to interact using the mouse

[digital palm]

the target is still the player controller, the view target is your character

[icy plover]

Okay. So the first UI level is that one #blueprint message . If I transition to the second UI scene which has either of these blueprint sets ups, the mouse still cannot interact in the second UI scene.

[lofty rapids]

why are you setting it then setting it back ?

wouldn't you just want to set it once ?

[lofty rapids]

this is in the level bp ?

[icy plover]

Yes. I got the fixed camera idea from this tutorial https://www.youtube.com/watch?v=3YnzCbrvfPI&t=607 . The solution that he has at the end for getting the mouse back does not work when going to a gameplay level that still needs the mouse

[lofty rapids]

did you create a new level or use the template like he did ?

i would imagine when the level loads it should possess the pawn in world settings

he just hid the mouse cursor, that doesn't set up the movement

[icy plover]

Okay, so going from UI level to UI level and in the second UI level, doing Set Input Mode Game Only lets everything work.
However, going from UI level to gameplay level and doing Set Input Mode Game Only does not work. I still can't do interactions with the mouse. When I do Set Input Game Mode and UI in the gameplay level it works!

I don't know why this took so long. Walking through it with someone really helps

[gritty wraith]

Excuse me whyyyyyyy?

I would like to create an image widget and assign it to a grid.

[wise ravine]

Did you create the widgeT?

[gritty wraith]

Theres no way such stupid thing is the only option... nooooo...

[gritty wraith]

no, i mean this image widget:

but using code

[wise ravine]

Yes that is a component inside the widget blueprint you should be adding

[latent venture]

I have this part which is also from a for each loop, and each then has some conditions like in the second image, how could I do in such way after it reaches the function "Add instance" to not go over to other then`s ?

[gritty wraith]

well its not displayed as an option in the Construct widget node

[gritty wraith]

as i just showed

[wise ravine]

The Image itself is not a widget blueprint, therefore you cannot construct in inside an event graph

[wise ravine]

In that node you add the actual widget blueprint

[gritty wraith]

ooooh i see i have to use the construct OBJECT node...

not WIDGET

[wise ravine]

Yes that would also work

[dawn gazelle]

If this is within a function, then you could technically use a return node after the add instance node which should stop execution of the rest of the "thens".
Your code could be simplified by using some boolean logic rather than several branches too...
Basically something like this:

[trim matrix]

Why not just create the widget yourself and then construct it? Way more customization that way

As in making its own widget blueprint

[gritty wraith]

that would not be a solution to my problem...

Now i don't know how to replicate theese settings in code.

position X will change

this is as far as i got

[versed sun]

well , after you add it to canvas

the "Slot as..." part is what you need

[gritty wraith]

Im no longer doing the image

i laready solved that

that was a different widget

[magic crown]

Now is there is a way we can permanently make input be on Game Only or something? Left clicking doesn't work correctly sometimes when Mouse Cursor is shown in PC because UE likes to constantly switch off Game Only input and go to UI or some crap. I don't understand how to fix? Cheers.

[gritty wraith]

actually is was the widget im now trying to position

[versed sun]

well whatever widget you want to position will work, as long as the Slot As type is what the widget is on

[hoary junco]

is there a way to create a trigger that only works if you enter it from a certain direction? The reason I ask is I want to create a corridor that infinitely loops if you go through it in one direction, but if you turn around and go the other way there's a trigger box that teleports you to a different part of the map

[versed sun]

sure , when you start the trigger, get the location of the actor that triggered it to find the direction of the trigger

[hoary junco]

and then would you do a branch of if the actor location on a certain axis meets a specific value at the beginning of the overlap then it activates?

[versed sun]

or, compose a 'Box' from 4 smaller boxes, each triggers a different overlap

[versed sun]

yes , you would want to focus on the Z

[gritty wraith]

nvm, got it

[versed sun]

if its close to 90, then you are heading east, or something like that

not sure what your level layout looks like , but theres a start

[hoary junco]

the problem with each triggering a different overlap is the trigger box can be walked through, so if you entered it from the left side, it would trigger when you hit the right side of the box group, I want it to be completely walked through one way and it do nothing, but when walked through the other way it triggers which means the solution around actor location being a conditional of the teleport will be a lot more effective

[versed sun]

2 boxes like this
when you trigger Blue, check to see if you are already in Red, If you are then you are moving Left

[lofty rapids]

dot product ?

[hoary junco]

idk what that is

[lofty rapids]

you want to know if your comming from one side or the other ?

[dense badger]

You... can... hold... shift... to... move... comment... boxes... without... moving... the... contents... 🤯

[hoary junco]

yes

[versed sun]

📷 neat

[lofty rapids]

idk much about it but you will get different numbers depending on if your looking in the same direction or opposite

there is a node

dot product

[lofty rapids]

or do what ryck is saying probably easier

[versed sun]

dot product is magic

[hoary junco]

so, when you overlap the blue box, if you're overlapping the red box too then it prints text?

[versed sun]

I think so, should only be 1 trigger once both boxes are overlapped

[hoary junco]

but how would that limit direction since you can overlap both boxes by coming from either direction?

[versed sun]

you want Red to Blue direction to respawn infinite loop of same room
and Blue to Red exits the loop and new level spawns
or something like that , right ?

[lofty rapids]

you can do dot product on begin and/or end overlap but you would be f'd if you say turned around in the middle your result would be off

[hoary junco]

yes

or rather I want the red to blue direction to do nothing because the player gets put in a circular corridor that has no exit, but if they turn around and go the blue to red direction they get teleported to the next area

[versed sun]

https://app.screencast.com/mPUVQY6kN2wf7

you can make it do whatever you need , theres how to detect direction

[hoary junco]

I guess that works then

[versed sun]

(except I messed up the left/right)

[simple field]

Any idea why is it not actually adding that material onto that static mesh

it's a toggle button to enable/disable a material layer

if material is enabled, it sets that material to none

if material is disabled, then it sets the material

[hoary junco]

one question btw, how do you get your wires to be that neat? mine are always a curved mess

[lunar sleet]

Your game

[vestal acorn]

element index 300?

[simple field]

I thought it was a hierarchy issue so I just set it to an incredible number

[vestal acorn]

probably try static mesh to print string to check if its getting the correct mesh?

if index0 is doing nothing

[hoary kraken]

how can i make a chicken ai for my game

[simple field]

It is getting correct mesh, when I set index to 0 it actually changes the material

but when I set it to 1 it's not showing up

it's basically a mask that is supposed to go above another material

[vestal acorn]

show the static mesh with material indexes?

0 = first material slot, 1 = second material slot

so if 0 is working, and 1 not , probably a material slot/static mesh issue

[simple field]

There's just 0 under the static mesh, do I add 1 manually?

[vestal acorn]

no

[vestal acorn]

set material changes the material set in the material slot, you cant add more dynamically as far as i know

[simple field]

Well I need two materials, the one with index 0 is my earth texture that gets changed in-game (highlighted countries appear), and on index 1 I'd like to have the borders material itself so that player can enable/disable the visibility of borders

[dawn gazelle]

Open the mesh you're using. There should be a section labelled "material slots" which can then let you add more slots. Whether it will actually properly display though, I'm not sure as normally you define parts of the mesh that the material applies to when you design the mesh.

[simple field]

How do I open a mesh

do you mean the pawn it's in?

@dawn gazelle

[dawn gazelle]

Find the mesh in the content browser. Double click it.

If you're using a built in mesh, then you may want to make a copy of it to make your changes to

[lunar sleet]

Don’t you have to edit the mesh with modeling tools to add more slots?

[simple field]

I tried but Material editing is disabled for some reason

[lunar sleet]

Is it a skeletal mesh?

[simple field]

static mesh

[lunar sleet]

Did you drag it into the map from the content browser ?

[simple field]

Yes

[lunar sleet]

Was this imported or something ?

[simple field]

Er no

I made it in UE

then I moved it into a pawn

and then I dragged in and dropped the pawn

[lunar sleet]

No

Take the static mesh

Drag it directly into the world

Then edit

It’ll change in the pawn when you apply

[olive pasture]

hi everyone. i want to place an image in a widget as a dynamic percentage of its parents total height.
for example 0.5 would be exactly half way vertically, 0.25 would be a quarter down.
is there any way to do this? does that make sense ?

[olive pasture]

oh i think i figured it out, with the anchors

[simple field]

Why is it not visible?

[versed sun]

Electronic Nodes Plugin

[maiden gale]

Hello, I have a question for you guys about enhanced input and blueprints.
I have created an input mapping context and added the number keys so i can assign them to action bar slots.
How do i get the display names from the input mapping to use in the Widget Blueprint? I have tried a load of things but cant seem to get an array to populate with any info.

Any suggestions would be greatly appreciated.

Im getting the following error in the output log.

LogScript: Warning: Script Msg: Attempted to access index 0 from array 'ActionBar1_KeyMapping' of length 0 in '/Game/Coast_Game/Blueprints/BP_CST_FirstPersonPlayerController.BP_CST_FirstPersonPlayerController_C'!

[agile moss]

The actor keeps setting its rotation to the Y of where I last looked at the viewport, but I want it to look only in one direction, help?

[trim matrix]

Will this function still continue down the execution line on false or will it honor the return nodes and only continue from those?

[gentle urchin]

You need to be explicit about early returns

(So instead of break, you can simply return the element on true)

Early return 🙂

So yes, it continues, as ypu have not been explicit about returning there

[warped juniper]

Hey there, I got this error while testing stuff. It did not cause a crash.

Blueprint Runtime Error: "Attempted to access BP_FireballProjectile_C_1 via property K2Node_Event_Other, but BP_FireballProjectile_C_1 is not valid (pending kill or garbage)". Node: Branch Graph: EventGraph Function: Execute Ubergraph BP Fireball Projectile Blueprint: BP_FireballProjectile

I have a fireball projectile that explodes on impact (spawns an explosion and destroys itself on impact with anything)
When they collide together, however, this warning appeared

[warm tree]

hey all 👋 wanted to ask if there's a CharacterMovement or Actor setting that replicates actor rotation that isn't Orient Rotation to Movement

[waxen mason]

I believe theres a RotatingMovementComponent

[warm tree]

hmm looks kinda like what I was looking for - thanks!

[trim matrix]

I see what you are saying. So, I dont want the function to return until the loop is complete, but you are saying the false will return on the loop until break. Which might explain the manner which my pawns are spawning. In that case, what should I do, because on the out side of that function the very next function is to spawn the AI pawns in the remaining player starts. Should I call an event on the loop complete instead?

[sick sky]

i actually trying to think of doing a "mop the floor" systrem

the idea is that I have a transparent plane to show the player the area, then detecting what % of the flat area he touched with the mop.

i was wondering if using some linetrace is a good start, of if i should use something else

[dull scroll]

I'm not sure if this is the right place to put this but I modeled a car in Blender for my game I'm working on but for some reason my car keeps pivoting, I don't really do the whole making the game work thing but I've been trying to learn and I'm just stuck.

All my mesh origins are setup correctly which are shown below, and I tried messing with the center of mass in my blueprint cause I figured it could be too rear heavy but that doesn't explain the pivot it does when it pawns in

[wise ravine]

@dull scroll #chaos-physics

and use this to troubleshoot your vehicle (#chaos-physics message)

[tough kiln]

It seems you're trying to access an element of the loop after the loop is completed. If I've understood your intentions, you want to loop through data, find the first one that matches your criteria, and return the transform, while also understanding which element of the array was used.

If this is the case, you should set the transform and index as local variables after your branch, then on loop complete, remove the index from the array and return the transform. Then you'll have your transform and an updated array to spawn the rest of your actors.

[lofty rapids]

this works fine though it doesn't return on loop body as far when you print string after it's after all the test prints

[warped juniper]

Hello, working more on my spell casting system.

Not sure how should I approach that system... It's something similar to having a different weapon on your hands every time.

I haven't made such thing before, thing is.

[lofty rapids]

what sort of spell thing, you want to have a certain spell on at any time ?

the more complicated version wout probably be GAS

[warped juniper]

GAS?

[lofty rapids]

Gameplay Ability System i never used it but thats basically what it's for

or you could just use variables also as an alternative

maybe a component or something

[trim matrix]

Dude! Duh. Yes why didnt i think of that. Thanks!

[warped juniper]

Well I don't think that's exactly what I was looking for

I had something very straightforward

The player can select a slot on the fly

When that slot is empty, clicking lets them use the inputs to cast a spell. Once cast, that spell is equipped and they can cast it freely until it runs out.

There are 2 logc gates here first. Checking if the slot is empty or not, which should be the easy part, and checking what spell is in that slot

Since the current spell has to be reflected in the UI for visual clarity.

[lofty rapids]

so a slot that fills up as you cast spells ?

or just a single slot for that spell ?

an by "slot" wdym ?

[warped juniper]

You know how in a shooter you can have different weapons equipped?

[lofty rapids]

ok so a slot that is linked to a keypress ?

[warped juniper]

Pretty much.

Only that slot is changed in a cycle since there are only 2 of them.

[lofty rapids]

you can already cast spells n stuff you just need the slot worked out ?

[warped juniper]

Yeah pretty much

I got the logic of turning inputs to spells

Now I just need that system to allow players to stash a spell, plus making more complex spell inputs.

[lofty rapids]

maybe #umg might know about a slot system like that ?

[warped juniper]

I could ask around... Thanks for the help

If my enemy jumps in the air and I lock on and slow down time attack, the camera and player does not reset with the player being tilted, any fix?

[finite hearth]

I am in collision hell, and I know the solution is probably a checkbox that I am missing.

When a monster dies, I set its collision to a custom collision preset, which ignores everything except for a block on WorldStatic. I also change the object type to DeadObject.

My landscape is a **WorldStatic **which blocks DeadObject.

However after changing the preset on the monster after death, the monster will fall down and clips through the world.

As an alternative, I've tried disabling collision and gravity after monster death, but it will still clip down.

What am I doing wrong?

Note: Multiplayer setup, but the change collision logic and being called on both client & server

To debug: I am trying to check the collision settings of the monster in PIE, but the dang things falls so fast I can't click it in time.

[surreal peak]

Try setting the movement mode to none too

[rain wraith]

Any recommendations on how to Save and Load arrays that are uniquely and repetitiously generated? In my level, the player can spawn pawns from a class which generates an array with unique data for each pawn and I'm unsure how to make a system for saving this array data.

[lofty rapids]

what kind of data ya got ?

you need to be able to serialize it i think

array of integers, array of strings np

array of structs idk but you might be able to change it to savable data

[trim matrix]

So this is a really good idea and I did implement it and it does work well. But even after sorting my array, triple checking at runtime with debugger multiple times, when the same level is re opened it gets messed up no matter what I do because the local player indexes actuall change! Player 0 becomes player index 1, and Player 1 becomes player index 0, hsomething like that, so now the question becomes what happens to these local players controllers when a level is re opened? @tough kiln

[lofty rapids]

#multiplayer might know more about that

[rain wraith]

There's four arrays in the pawn class that need to be saved, all are transforms recorded from the VR Controller.

Does an approach like this seem reasonable? Every time a pawn is spawned it gets added to the ExistingPawns array > For each loop of the array > Get the CapsuleTransformData and append it to array SavedCapsuleTransform Data (which is stored in BP_SaveGame)

And then to just repeat it three more times for the other array transforms in the pawn class

[lean jasper]

Hi everyone ^^ !

I would like to not only add an easter egg, but also a functionality to my Melee Character : how to detect if a player's left thumbstick made a full rotation ?
How to then check if it made multiple rotations ?

I'm compelled to use BPs only, and I have absolutely no clue how to make it properly (if possible, without using Event Tick, but that wouldn't be too problematic if there's no alternative).

Thanks for your attention !

[lofty rapids]

looks legit to me

[warped juniper]

@lofty rapids I couldn't get any help on umg, but I tried to come up with some logic system...

So for starters, I made a struct.
It stores an int, for the slot
A string, for the ID of the spell
And a boolean to check whether or not it's open

Hmm... But in second thought checking for null in string does the same.

[lofty rapids]

i would use an array

maybe even just 0 for empty, 1 for occupied

you got to be careful with structs in bp
i hear they can break your project

[rain wraith]

How would one go about loading this data back to the individual pawns though? Not very familiar with arrays but I believe appending just adds all the input array into one larger array. So each CapsuleTransfromData stores 80 Indexes. How would the code tell it to send the 80 indexes of transform data to index 0 of the stored pawns, then index 81-160 to object index 1 and so and so on for additional pawns

[warped juniper]

I need something that stores both an int and a variable string

[lofty rapids]

well the index could be the slot

so index 0 is slot 1

[rain wraith]

Sure for the objects. But then how does the game know that object index 0 should recieve transform index 0-80

[warped juniper]

Well I have no idea why or how

[lofty rapids]

right just be careful with the struct make it and leave it if you can

[warped juniper]

But the character lost the ability to move at all.

[lofty rapids]

is your camera working ?

[warped juniper]

Yes.

All input works, just not any form of movement.

[lofty rapids]

the actual movement event is firing

when you press the keys ?

[warped juniper]

This is the error

Blueprint Runtime Error: "Accessed None trying to read property CallFunc_GetMovementComponent_ReturnValue". Node: Set bIsInAir Graph: EventGraph Function: Execute Ubergraph First Person Anim BP Blueprint: FirstPerson_AnimBP

[warped juniper]

And yes.

[lofty rapids]

where does it take you when you click on it ?

[warped juniper]

The anim bp

[lofty rapids]

show the nodes

accessed none pretty common the thing your trying to access is most likely empty

[warped juniper]

Nothing is affecting the movement now

Not even gravity

What nodes specifically?

I changed nothing of the movement

I just added some of the spell slot functions and then it just broke...

[lofty rapids]

did you already have a ui ?

a widget was already on the screen or you made one ?

did you set the game mode at all ?

[warped juniper]

I have the same game mode as I had

I genuinely changed nothing but what I mentioned of the spell slot system

I tried the default character bp and it works as normal

[lofty rapids]

well i'm just going about debugging

usually check the events are firing

first then see if you can add input another way

like a hard coded key press or something

seee if you move

[warped juniper]

No you don't see

It's not input

No form of character movement works

I move it up, it remains static, cannot detect anything in regards of falling and such.

[lofty rapids]

your character animation is playing ?

the idle or whatever its set to

[warped juniper]

Yes, it is.

[lofty rapids]

or is he idle or falling ?

[warped juniper]

Idle

Just idle.

[lofty rapids]

so it's not falling thats weird and if you take out the code you put it does it work again ?

or it's broke ?

also does it break at a certain point, or it starts like that ?

[warped juniper]

It broke

It starts broken

And even if I remove all I added, it remains broken

@lofty rapids What would have even caused this... How do I even fix it?

[lofty rapids]

well your events firing so thats good, you did a print string on that ?

[warped juniper]

Yes.

I can move the camera

The character is just permanently stuck in a fixed point in space.

[lofty rapids]

in the character goto details

search gravity

show what it says

[warped juniper]

It's 1.

I think this is all just corrupted...

[lofty rapids]

whats 1 ?

ya it definately could be

but hard to tell with out going through a bunch of stuff

[warped juniper]

It's 1 gravity.

[lofty rapids]

your gravity scale is 1 ?

[warped juniper]

Yes.

[lofty rapids]

and enable gravity is checked ?

[warped juniper]

Yes

I did not change it

And besides

It cannot access the character movement component itself as shown in the error log.

There isn't a no gravity problem, but a no character component problem.

[lofty rapids]

are you pulling of something that has that component ?

what does that look like ?

[warped juniper]

It's the default character movement component

[lofty rapids]

so you used a template then

and when your in the character can you click on the component and get details ?

if your details is blank it's a bug

and if your character is all f'd up, what version are you on ?

[warped juniper]

Yes, all details are blank.

I'm on 5.3

[lofty rapids]

yep thats a bug

is it blank like not displaying anything ?

[warped juniper]

So I'm using the one version of UE that randomly destroy itself?

[lofty rapids]

i think so

[warped juniper]

And yes, it displays nothing. Again.

[lofty rapids]

good time for backups or source control

[mighty kernel]

Anyone know a quick way to get a landscape's height given X and Y coordinates?

[warped juniper]

I'm checking for the autosave backups

See if something can be salvaged

[lofty rapids]

perhaps a trace ?

on a custom channel

line trace by channel

get the point

and then subtract where your zero is

or if you landscape is at zero z, your all set

just trace and get the location

split the pin and get your z

[twin shale]

Question: Once upon a time I had a collision sphere around my player I used to turn stuff on and off at a distance. It ended up checking so many things per frame that my frame rate tanked due to the collision sphere moving each frame. I made a custom component that just checks the distance to the closest player and sets the tick rate accordingly. If no player is within X distance the tick rate reduces to once every say 8 seconds. This works fine right now but we're going to have thousands and thousands of actors that have this code (everything interactable in the entire world). I need to find the most performant way to turn features on and off based on distance. Any ideas?

[warped juniper]

Alright... Thank god

The backup worked and I recovered everything.

[lunar sleet]

Setup source control

[lofty rapids]

how were your checking the collisions on tick exactly ?

c++ will help with larger loops

[twin shale]

Each component just checks distance to all 4 players on tick. There's a sliding scale so the tick rate increases the closer the closest player is. Depending on distance this can range from every 0.3 seconds to over 10 seconds if the distance is vast

[lofty rapids]

so it's only checking 4 players, or you said thousands

[twin shale]

Thousands of actors are checking against 4 players. Basically every item in the world regardless of distance is doing these checks

[lofty rapids]

so each item will be searching the 4 players on tick, is that correct ?

hmm

[twin shale]

Nope, I cache the 4 players as they log in and out. They're just pulling from an array and checking

Then they dynamically adjust tick

[lofty rapids]

checking actor location ?

[twin shale]

Yes. They get both actors location and do a distance compare

So theoretically only say 200 actors are high tick at any point

[lofty rapids]

ya i c, seems like a lot

i would move whatever you can to c++

[twin shale]

My general question I guess is would moving this back to something like collision spheres be a good or bad move? I can limit to only pawns but it seems like doing that would still be a lot more costly

[lofty rapids]

collision spheres on each item ?

[twin shale]

This will probably move to C++ in the future but it's not moving just yet. I guess I can bump that priority if needed

[mighty kernel]

This worked brilliantly, thank you!

[twin shale]

Probably each item so it's not moving each frame. I think the sphere moving each frame the first time is what really tanked my frames

[lofty rapids]

so the frames went down even when nothing overlapped ?

[twin shale]

When I had the sphere on the player it was set to something like 40 meters and it was checking literally every actor and mesh I passed as I walked. I had to chase it down with insights

[lofty rapids]

maybe make them idle within a range

[twin shale]

I also have a number of different things that had to happen at certain distances. I couldn't imagine putting several overlap spheres on there

Make the collision go idle after a certain distance you mean?

[raw pilot]

Since i cant copy and paste a 2nd tick in my blueprint, how can i make one as a custom event? just add the float DeltaSeconds and it works the same?

[lofty rapids]

well make the tick go idle and not keep getting untill the character reaches a collision set on the actor

[paper smelt]

How do i get bone name with line trace?

[lofty rapids]

split the out hit

[twin shale]

I could give this a try. I don't know exactly how collision works in C++ but I have to assume they're doing smart, fast checks

[lofty rapids]

c++ just makes everything faster

when your dealing with a large scale especially actors to loop in an array

in the thousands

it's really the only way to make it work

if you have 1000 in range thats 1000 loops * 4

bp is just not built to handle it imo

it will eventually crap out

[twin perch]

Question, i have a Length, its a float, i have a normalized vector, i want to increase that normalized vector by the length how would i go about doing that. youtube is telling me i gota do matrix math ?

i want to keep the original vectors rotation ect ect.

[lofty rapids]

you should be able to multiply it by the float

but actually idk if that will you give you what your looking for

[twin perch]

multiplying didnt work unfortunately

[lofty rapids]

matrix math isn't that bad

you just do the math in order

if you have a matrix

multiplying a vector by it is just a matter of doing in a certain order

[twin perch]

well there is Get Scale Vector (matrix) ... but ive never used that i sware their is a simpler way of doing it.

[lofty rapids]

but matrix math can also just be broke down to a formula

what does the matrix look like that they want you to use ?

or do you need multiple ?

[twin perch]

hmmm ? its a blueprint node called Get Scale Vector i asume it scales the vector which is what i want right ?

[lofty rapids]

idk never used it

[twin perch]

hmm all good im gona do more google fu cheers for the help!

[lofty rapids]

but i imagine you want set

[frail swan]

When I jump into the edge of a platform, I get stuck on it. When I jump over the ledge, I clear it easily. How do I prevent getting stuck?

[twin shale]

I think I'll move this to c++ in my optimization pass since it will be a bottleneck. I'm kinda wondering if I can limit how many entites are checking locations by adjusting World Partition distances

[twin shale]

your capsule is not clearing the ledge

[frail swan]

How do I prevent it from interrupting the vertical momentum?

even if the bottom edge of my capsule hits it, it gets stuck

[lofty rapids]

you could try to change the capsule half size, or size

i've never done it but it's worth a shot

you could make it smaller when your falling

or when you jump

then set it back when you land

[frail swan]

that might be worth a try. To match my character's curled up legs... Ideally I'd like the capsule to just slide up the edge. I don't want my jump's height to be affected by whether or not I hit a wall

a ceiling, sure

[lofty rapids]

well unfortunately the animation doesn't change the capsule

[frail swan]

Yeah but what I'm saying is this isn't a matter of the character size. A jump that doesn't hit the wall gets me that high, but if I hit the wall, I don't get that high.

[lofty rapids]

i think you might be able to adjust step height as well

maybe step up it

[lofty rapids]

its the "capsule" size

goto your character

and look at the capsule

thats whats hitting it

that pill shape thing

[frail swan]

I understand that

[lofty rapids]

but i would also check out step height

see if you can get that sliding effect by making that a bit higher

but then you would need to change that on the fly

or you could leave it but your regular step height will be a bit larger

idk if that would work considering your not walking

but it's also worth a try

or also #animation might have some tricks

[warped juniper]

I'm not too familiar with it... Any info you reccomend?

[twin shale]

What's your team/project size?

[frail swan]

I just am having a hard time understanding why the upward velocity stops all of a sudden. As you can see, the capsule is sliding along the ledge just fine until the bottom gets there, and then I'm suddenly suspended with no velocity for a moment

[warped juniper]

For now, just me, although it will most likely expand.

[twin shale]

Size? 100MB, 9999TB?

[lofty rapids]

normally irl you would tip over with velocity but it makes sense you would just stop it's quite a bit of coverage there to stop the capsule

its not actually using the collision of the mesh

your using the capsule collision so it's getting stuck

you can try to adjust the capsule idk how that would look upon landing tho

[frail swan]

I feel like we're talking past each other, but thanks for trying to help

I really do appreciate it, that probably came across really passive agressive

[warped juniper]

Just basic files for now so less than 2GB

[lofty rapids]

are you talking about how your character just stops and doesn't have force applied or something ?

[twin shale]

This is basically the default behavior of the CMC. If you want to keep going you're going to add custom code in some form to change the capsule size/detect ledges in some form to keep the player momentum/temporarily ignore the platform collision/etc... or override some of the CMC to make it do what you want.

[frail swan]

If you watch my first gif you can see that my jump is able to clear the ledge and then some just fine , if I don't come into contact with the ledge on the way up. My capsule goes well over it. Also, if I jump against any other wall, my upward momentum doesn't seem to be affected. But if there's a ledge at the top of the wall, the capsule "catches" on the corner of it

[frail swan]

This is kinda what I fear

[twin shale]

Github LFS on Azure DevOps I believe is still free. Easy enough to set up and use solo, and will expand for more users later. Multiple users and locking is a PITA but can be done

[twin shale]

The "laziest" thing I can think of is do what @lofty rapids suggested and just use an anim notify state in your jump to shrink the capsule during a window of the jump.

[lofty rapids]

or do the line trace and disable collision that was a good one two, theres some issues with either way

[twin shale]

Oh yeah, either one. If you're going to do that I'd probably add an extra collision channel to platforms in the middle so you can treat them differently from the ceiling and the floor

[frail swan]

I do plan on implementing one-way platforms. I need to do some testing and see if this only happens on thin platforms like this, or if it also happens on plateaus that go all the way down to the ground

[lofty rapids]

i would probably try both see whats smoother the changing capsule size one i kind of see it jumping up sort of glitching but i never done it

i also have the same thing happening in some of my projects i have not fixed it yet so it's nice to get some ideas

[frail swan]

Yeah it happens on thick platforms too. I'll have to fix it somehow, but that's a future me's problem

[twin shale]

I'm not doing sidescroller but I'd personally probably detect ledges during jump and play a small step-up-on animation when you approach an edge. I'd imagine it would look the most natural

Cause from your video it's doing pretty much what I expect it would do

[twin perch]

Ok got a slight issue, my code works the issue is Attack Distance needs to be a negative to work

Is their a node that flips a positive into a negative, abs flips a negative into a positive, is thier a reverse abs ?

[twin shale]

X -1 flips either direction

[lunar sleet]

See bonkers’ guide in #ue5-general pins and then use Azure

[twin perch]

@twin shale sorry could you please give me more information ?

[twin shale]

AttackDistance x -1.0 float

[twin perch]

@twin shale ah! right times it by -1 cheers that worked thank you!

[warped juniper]

Fair. I'm used to workng with asure from before...

I get it's a pain to actually add people onto it though.

[trail goblet]

Not sure if this is the right place, but i've been making this in BPs. I've created a custom hover vehicle and it weighs about 2 tons, yet it cannot push over very light objects at any speed. Yet the sadan can do it at even slow speeds. Im unsure why this is the case.

It also floats down very slowly compared to the sedan as well. Would anyone have any ideas what would cause this?

[twin shale]

No idea without looking at loads of settings but my immediate thought when looking at this is you're not properly interacting with the other actor. Generate hit events is off or not properly simulating physics or channels or something

[trail goblet]

Just default settings :/

Physics works because it still interacts with being shot. That's why im so confused

Yet it feels like it has no force when it collides with something

[trail goblet]

Would using a FloatingPawnMovement do anything to this? (Nothing changed)

[devout wave]

hey! I was looking into making a climb for my game but having trouble with anything feeling good, I played some Diablo 4 this weekend and the traversal mechanics would be perfect, it is essentially an automatic climb when triggered in a hit box. Tunic does similar... would this be done using a timeline in unreal or is there another way I could do it?
Thanks!

[lunar sleet]

You can switch repos anytime rly

[trim matrix]

Hey, first time i meet this bug, BlueprintImplementableEvent won't show up on Blueprint graph, so weird. The function is still there but no event. Tell me if you know anything.

(got it, was the "const")

[warped juniper]

Hey, I'm thinking of using the Gameplay Ability System in my project, but it's not an RPG. Instead, it's more of an action game with a large number of skills... Some of them are shared between players and enemies, with important changes to their behaviour and visuals.
Would my case be a good situation to implement GAS? Or should I use components and such?

[trim matrix]

Sound like you can use GAS. Faster than implement your own system anyway, why not

[warped juniper]

Alright... Then I should see how to implement it.

As a simple explanation, though.

The idea is that the player inputs codes to cast spells.

I would probably have to make minor extensions to the system to support that player side.

[worldly urchin]

what is the difference of just using keyboard 'F' event and using an Input Action? Which is better?

[warped juniper]

The F key event is EXTREMELY rigid in logic.

It checks only the frame it receives input, and the frame it strops receiving.

Because of this it has no amount of flexibility and is even prone to errors in some use cases.

[trim matrix]

Those keyboard event is just for debugging

[worldly urchin]

ok thanks

[remote meteor]

F is just F
IA_Flashlight could be, iteral many anything else, including gamepads, gestures, virtual triggers from code, rebinded keys, etc etc.

[warped juniper]

The Input event gives you.
The moment the Trigger becomes active
The moment the input assigned to the event is first pressed
A tick event as long as the input hasn't been cancelled or finished
The moment you let go of the key before trigger
The moment triggering has been completed and nothing else is left to do.

The most important part of Enhanced Input is setting the trigger.

You can make virtually any possible interaction if you are smart

For example you can have a Hold input for events that you want the player to hold down a button, for example to turn a dial or valve, but have a Start event as well to simply press a button.

Or in a fighting game you can have a button that does something if you tap the key, and something else if you press the key while also holding down a different key.

Possibilities are as many as what you can figure out... I just wouldn't ship anything with hard coded key interactions.

Except maybe a Konami Code? That one gets a pass.

[thin panther]

Even then I'd still rather map it to actions, who's to say you can't use a cheat code because you use an alternate layout, a foreign keyboard, or an accessibility controller

[warped juniper]

Yeah, that's a fair point as well.

Not to mention EIS handles player custom buttons by itself. That's a load off your shoulders for something every player will want.

[south ginkgo]

Hi! Just a quick question. I've been trying to find a way re-update my player references upon respawning and found this post: https://www.reddit.com/r/unrealengine/comments/cg3i6h/for_single_player_game_whats_best_way_to_handle/
And it seems that OP found a solution but I don't quite seem to understand it. I'm just kinda confused on where exactly this code would be placed like if it's in the level BP, or elsewhere and what exactly would be the BP_myController. I'm pretty new to UE5 too, so forgive me if I'm a little slow.

[bitter star]

Hi guys, I'm trying to make a blueprint that spawns an actor (Gas 1unit) with an osc message and checks if there are other actors present (Gas 2unit A & Gas 2unitB) and if so destroy them. This is what I've done so far and it "works" but i get errors from the message log (Blueprint Runtime Error: "Accessed None trying to read property Gas2unitB". Node: Branch Graph: EventGraph Function: Execute Ubergraph BP OSC Server Blueprint: BP_OSC_Server) that points to my last branch of the chain (the one that goes out to destroy actor). What am I doing wrong in the bp? Note: the gas2 unit A & B may not have been spawned yet at the moment the action is called, but it shouldn't matter as I've added the isvisible bool. Or should I spawn all actor and hide them all then call visibility toggles with my osc message instead of spawn and destroy?

[dawn gazelle]

This is one of the issues of storing refs to something that may dynamically change during gameplay. You don't want to have everything using additional dispatcher logic just to keep itself updated with the new ref. The code you've displayed would need to go in to any actor that wants to maintain a reference to the Player Character, and yes, that means any actor that wants to keep itself updated when the player's pawn changes.

An alternative would be to create a blueprint function library with a getter function for your custom character class, allowing you to easily get your character reference from anywhere, and anything that needs to use a reference to the character can just request the reference at any time.

[frail swan]

If I turn off "use flat base for floor checks" it doesn't solve the problem per se, but it changes the nature of the problem. Now my character does make it on the platform, but they "snap into" walking, even if they still had a bit of height left to their jump. Arguably better but still not what I want

[dawn gazelle]

The issue is that you're trying to reference something from Gas2unitB (the Root Component) and as you've said, it may not necessarily be spawned, and because it's not spawned, you can't access the Root Component of it, so then you get this error.

To fix this, you can check if it is valid first before doing anything with it, and only if it is valid can you attempt to access values from it and destroy it.
This means you may want to use a sequence here after your first branch so you can check both of your Gas units individually and destroy them if necessary.

[bitter star]

Thanks, it makes sense. How do you find the Get is valid node?

[dawn gazelle]

You can right click on any normal get of a reference and convert it to a validated get.

[bitter star]

Awesome, I've never done this, thanks for the tip!

[bitter star]

So with this I dont need the is visible function anymore do I?

[dawn gazelle]

Up to you if you want to check if the thing is visible or not.

[lunar sleet]

speed of what

ok, so what's the issue you are experiencing exactly?

Oh

You’d prly need to do some maths to change the track output

[bitter star]

What node should I use to invert the vector direction of a value? For example if my value is 200 I want it to become -200

[lunar sleet]

I’m thinking you can maybe get distance to actor at the start, and divide the track output by it before plugging it into the lerp. But you’d need to test that theory. #game-math would prly be more useful than me

[lunar sleet]

Multiply -1

[bitter star]

Thanks!

[trim matrix]

Is there a delegate that fires when the world has fully loaded that I can access in blueprint on the game instance?

[thin panther]

No

[hardy mango]

Streaming Levels - how do i set this initial state for this MISSION MAP to NOT be loaded?

when I play the game - this level is visible.

[hardy mango]

is this appropriate? This works but it feels like there is supposed to be a setting somewhere to set the initial state of this streamed level?

all docs say to use Blueprint or AlwaysLoaded - thats the only 2 options....

[surreal peak]

@hardy mango have you tried the Visibility setting?

[hardy mango]

the ToggleVisibility (Eye icon) ?

[surreal peak]

The entry in the menu you are showing

Second from the too

Top

[hardy mango]

same as the eye icon....

it temporarily (editor when not in PIE) hides it

[warped juniper]

Hey there, just want a quick hand here...
I'm trying to make a simple explosion expand over time based on its lifespan.

[surreal peak]

I'm relatively sure the level should be unloaded by default if you set it to Blueprint... Hm

[warped juniper]

I tried using the Event tick delta seconds but it ain't doing anything, sadly.

A timeline isn't ideal either since I want the duration to be dynamic.

[surreal peak]

Which they can be fwiw

[warped juniper]

I don't know much of them sadly... How can I input a float to adjust their length?

[surreal peak]

Make the Timeline 1 second long and set the PlayRate to 1 / Duration

[warped juniper]

Ahhh thank you... And that retains all easing as well?

[surreal peak]

Should yeah.

The Lerp is linear so if you want to recreate that without a Timeline you need to use a Float Curve asset

And then count up some float variable on tick to know how long the actor is alive. There might be a variable somewhere that gives you that already but not sure what it's called or if it's BP exposed

[warped juniper]

Thanks so much for that, you're a lifesaver...

[surreal peak]

That counted up variable is then divided by life time and the result clamped to 1.f and fed into the get value function of the float curve

That's the alternative solution to the timeline

[warped juniper]

I think a timeline should work though

It wouldn't cause issues if spammed multiple times I hope...

This is for an explosion.

[surreal peak]

It resets fwiw. You wouldn't call this in Tick

Right but one explosion is one actor, right?

At least it should be

[warped juniper]

Yeah of course

It's one actor with a matching particle effect

Plus the overlap event to check for damage.

@surreal peak It works excellently, thank you!

Now I just hope my spell system holds up...

I feel this will make some people cringe.

The way it works is that it checks for the current spell the player holds and executes the according function.

Each spell has alternate player actions besides the basic M1 fire event... But I'm at a loss for making this more efficient.

Specially for creating more complex systems.

I would like to have something similar to the U5 first person default FPS gun... The gun itself holds its own input logic that overrides the players

I just cannot crack the code for it.

[teal sky]

tryign to make an on clicked event for this gun, where the cube detects when it is clicked. the cube doesn't really fit the gun though that well. does anyone know of a better way to do this? perhaps there is a shape i can use besides a cube that is more customizable

[surreal peak]

@warped juniper Singleplayer ?

Your system is basically lacking any kind of Object Oriented Programming.

[warped juniper]

Yeah, it's singleplayer 100%. No plans for making any form of multiplayer.

[surreal peak]

Your Spells should be their own Objects

[warped juniper]

Definetly because I'm not a programmer.

[surreal peak]

BP_Spell which should have some functions like ActivateSpell with some generic information passed in. Then you can inherit from that and make a BP_Spell_Fireball.

Override ActivateSpell in there to do your actual Fireball stuff

There might be more functions you need, and some more boilerplate stuff

You would probably also have a BP_SpellComponent which is a child of UActorComponent which should take care of the spell system in generall

E.g. adding spells or activating the right one

[warped juniper]

Hmm well the current system I have for selecting spells is a pretty weird but "functional" one

[surreal peak]

You can try to activate spells by matching the class or give them some GameplayTag to identify them

[warped juniper]

Player input is translated to an ID

[surreal peak]

Your system looks like almost everything sits in the character

[warped juniper]

The ID is converted to a string and then that string is what drives the spell once cast

[warped juniper]

That's the case sadly. I'm not a coder by choice... I'm currently doing this out of absolute need.

[surreal peak]

You can still do that. Input can be translated to a GameplayTag and you then tell the SpellComp to activate that

SpellComp loops the abilities and checks which one has the tag

You should really not code the system into the character

It will bite you really quickly

And since you are doing Singleplayer stuff you can use Objects easily I guess

[warped juniper]

I really wish I could follow you better here. I'm really not at the level you may think I am.

I cannot fully grasp what objects are in this case.

Just the absolute base class type?

[surreal peak]

Object is the base class of basic almost everything in UE. The are also the most lightweight class you can make

[warped juniper]

Alright.

[surreal peak]

They can't be placed in the scene for example. That only starts being a thing with Actors

But for a spell they also don't need to

[warped juniper]

Currently I have my spells as a BP Component...

[surreal peak]

Yeah...

Idk. You should learn a bit more than I would say. You will code yourself into a mess sooner or later other wise

The system you make there scales really poorly

[warped juniper]

Sadly that's how college life is.

They half teach you JS and throw you into the engine to make a proof of concept in a month.

[surreal peak]

Game Dev college?

[warped juniper]

Hey, it's free.

[surreal peak]

Yeah idk. I never thought that made sense

[warped juniper]

It's mostly for the business studies.

[surreal peak]

I studied generally math and IT and learned the Game Dev stuff myself with a then very nice base of knowledge

Two of our employees went to a Game Dev University. Can't say they seem to have learned more than anyone going to a normal one and learning Game Dev manually

[warped juniper]

I'm not quite good at self teaching most things... More often than not I just don't know how to properly train myself.

[surreal peak]

They are lacking a lot of base knowledge due to that actually

[hardy mango]

i myself have a computer networking degree (Cisco/MS Servers) and never used it.... 12 years IT work.... self taught myself programming + game dev

i full heartedly agree/stand-behind self learning.

college is a joke

[warped juniper]

I guess it's just a mistake... Really I'm just carrying on with this because I'm so close to the finish line.

[surreal peak]

Totally fine

[warped juniper]

And if I abandon now I would have wasted years for nothing.

[surreal peak]

Just sharing experience

[hardy mango]

yah - and its a rough point in life - businesses/corps push "NEED BACHELORS"

[surreal peak]

My bachelor degree is also unused

And I never went for a master one or a doctor title

After all I founded my own company and no one cares about this anymore

[hardy mango]

but - it gets you foot in teh door... you do learn good things though

soft skills

people/project management

[surreal peak]

But the knowledge I got from studying was worth it

[hardy mango]

core skills that develop you as a person.

[warped juniper]

It's pretty bizarre, really.

[surreal peak]

Game Dev college is not bad. I just don't think it's the best alternative out there

[warped juniper]

Most of my focus was on more general art elements of the game dev pipeline

Like the general area of 3D art such as shaders, rigging, models, texturing and whatnot.

[hardy mango]

college is a good INTRODUCTION to topics i find

[warped juniper]

But having to do all the college stuff made me neglect it, as all the 3D related elements get skimmed over with redundant subjects I mastered long ago.

[hardy mango]

its good for people that cant self-learn

sets an agenda & topics to go study

but

[warped juniper]

Yeah, but if college can't help me now, what's my other option?

[hardy mango]

if you take college - and dont put in 1000+ hours on the topics to develop/go above & beyond.... you're not going to get into the industry on your degree alone

[hardy mango]

study bud

tons of study

[warped juniper]

I would love to do that, genuinely.

But there's a lot of stuff bothering me

[surreal peak]

Idk how it is in your college but I think here they give you art and programming basics and then have you take a path.

And at the end of the day you gotta make some project with a small group of people which will probably just about work cause everyone is lacking actually experience

[hardy mango]

baby steps

[warped juniper]

Every time I feel I made some progress to set some form of consistency, I just fall back.

Like, I stried to sculpt every day to improve my skills. And it started giving some results.

[hardy mango]

my suggestion - get with someone good - learn together.

THis also is hard in this industry .... its hard to find good people in a FREE MARKET such as game dev

[surreal peak]

@warped juniper I've been out of Uni for 8 years or so. And also working with UE4/5 for 10 years. I'm still learning

That's how it is

[warped juniper]

But sadly I couldn't keep it up.

[hardy mango]

ALWAYS learning

[warped juniper]

Imposter syndrome just gets the best of me. How do you beat that invisible hand just pushing you down?

[hardy mango]

start a learning project. set an attainable goal... SMALL.

FINISH IT

9/10 peopel cant finish a project

= failure from the start

[surreal peak]

Socializing imo. You aren't alone. Almost everyone struggles with it, even the ones where you think are masters of what they do

[warped juniper]

I'm not talking exactly of entire games regardless of size

But goals...

I want to improve at digital art, but can't keep a good streak of art made every day.

[surreal peak]

In your current stage you should probably do what is the most fun for you

[hardy mango]

well this is on you my man... you gotta keep motivated.

Think of big success stories - Valheim, Minecraft..... ask yourself - "Do I want to be one of N# of devs that made 80 million $$ for their 2 years of work?"

[warped juniper]

I love design above all things, really.

The puzzle of making things fun and engaging, or look interesting and unique.

[surreal peak]

Try to find like-minded people fwiw

[hardy mango]

i'm the same! I love design..... brinigng things to life through logic

[warped juniper]

But currently, I need to prototype a proof of concept in a month.

[surreal peak]

You have a 100k User Server here. Use some of the social channels

And find some peeps that do and think the same to talk to

[surreal peak]

Yeah there are times that you will have to sit through it

[hardy mango]

my suggestion - small scope. for college - think of "A character is in a room and has to pick up an object, which sets off a trap - and needs to escape the room or dies"

[warped juniper]

Because the college says so. And that's just beyond absurd when the only dedicated programming class we ever had was using JavaScript for Phaser browser games.

[warped juniper]

They are also grading us on uniqueness and originality.

[surreal peak]

Yeah we have a lot of peeps like you here that got told to make something in UE but never got much stuff taught about it

[warped juniper]

Which could mean anything.

[hardy mango]

start with a subject like that - then expand on it if you have time.

make it shine

[sick sky]

Any ideas

[surreal peak]

I doubt any college professor would actually objectively review something as unique

[gentle urchin]

^

[surreal peak]

So just go with your gut feeling

[warped juniper]

Honestly my college stories are a nightmare.

I worked with people who demanded final-quality character models before a prototype was even set up.

[sick sky]

What studies are you doing ?
Programming, game design , ... ?

[gentle urchin]

Bring up a AAA prototype

Hzd got some prototypes out and about

[warped juniper]

People who told me to forget the color palette, then color the characters themselves and set up the lightning, only to then complain about the characters having low visibility.

[sick sky]

For us its the opposite
We are focused on game design et game feel before starting the visuals

[surreal peak]

I gotta start my day and leave the convo. Please consider moving to a social channel like #lounge , #programmer-hangout or similar. Or something more #career-chat like. BP questions are getting drowned out.

[warped juniper]

It's just a pretty demoralising experience. I want to improve, I want to be great at what I want to do, but I feel demolished thinking the time I could be spending on mastering some crafts is spent on a place like that.

Yeah, we got carried over. I'm sorry for that.

[surreal peak]

No worries.

[abstract schooner]

Hey Guys,
There is no UI or Wdgets forum, so I'll ask here I guess..

What is the trick, feel free to link some docs or tutorials.
How do we combine CommonUI widgets with UMG widgets?

I have an asset from the MP that uses CommonUI that works great, but I also have quite some normal UMG widgets that stop worki g the second time they are created.

I'm not sure if it is due to them being different types of widgets or if it has to do with changing the InputMode or something..
But I can't be the only one running into this?

[hardy mango]

there very much is -you have to subscribe to it in your ROLES.

[verbal jungle]

quick question, if i make an array, and then remove an item from said array, does the array shrink? or is there jsut an empty item there

[hardy mango]

simply removeItem - then debug string the array size -

I was trying to find an answer for you but i'm not finding what i want to see.... in C++ you can array->shrink() because it states that arrays dont shrink automatically (copilot).... i would still suggest debugging it after removing item.

I recall there being a boolean on the function bShrink? or something to that nature - but i dont see this .... not in 5.3

there is no SHRINK node in blueprints however

[verbal jungle]

yeah i was rummaging around in the blueprint node menu and found none

[lunar sleet]

There’s Resize Array

[verbal jungle]

guess i could work with that

[sick sky]

so in UE, it can add slots if you add items, but it wont shrink when you remove ?

or is this a c++ array behavior

[lunar sleet]

I think it shrinks but the indices don’t get resorted automatically

So if you iterate over an array you removed an item from, it’ll cause some issues

[sick sky]

because from memory they shrink

[hardy mango]

literally debug it - you'll find your answer

array->removeItem(item)
printString(array.length)

if you have 5, remove = 4 (expected)

print string = 4 - you know it shrinks automatically

[verbal jungle]

so if i remove the 3rd item in an array of 5, does the 4th and 5th items get moved "up"?

[lunar sleet]

From what I’ve experienced, the indices break without using resize

[hardy mango]

this is referred to as "shrinking"

again i remember this being a boolean value on the operation .... but i'm not seeing that in 5.3

[sick sky]

in 10m i can test this

from memory the indexs are updating after a remove

i did a lot of stuff with arrays and never got issues

[undone bluff]

you will need an entry that represents an empty slot

you can't actually have an empty array index

[bitter otter]

hi guys,
I have an actor that can be destroyed when shot and i have it used to my enemy actor blueprint (like a weakspot), since the destroy logic is in the original actor, im struggling to have it lower the enemies health when destroyed,
does anyone know how to fix this? (sorry if its easy, im pretty new to unreal)

[undone bluff]

it either has a value or it doesn't exist

[undone bluff]

Your enemy should save the references when it spawns them

[sick sky]

@verbal jungle @lunar sleet @hardy mango
looks like (in BP atleast) the array is resized and updating index

[hardy mango]

debugging ftw

[bitter otter]

sorry, im pretty bad at this and don't quite understand, since there are many enemys, all sharing the same weakpoint actor as one of their components, with the weakpoint logic being in the weakpoint actor as to not repeat it alot as each enemy has many points, how can i check when it is destroyed in the enemy actor to lower health, while not lowering the health of all enemies through a custom event or something?

[frigid summit]

hi guys how to speed up the charcter using set timer by event and add movement input nothing work so far including set max walk speed

[gentle urchin]

Custom events doesnt happen on all instances

Only on the one you invoke it on

[bitter otter]

thanks, that kinda works, one issue however, if i get one enemy down some health, then try attacking another, the health is carried over to the new one, while also counting for the health of the old one, what can i do?

[gentle urchin]

probably got some logical flaw there ^^

show some code

[undone bluff]

All instances are entirely separate objects

[gentle urchin]

and have their own values

but if your UI is stuck to the old instance or smth, then its a coding mistake

[abstract schooner]

Ooh shiiet! Thanks! 😁

[nimble citrus]

Hello, I'm working on merging two objects into one. Currently, there are two small objects tagged as 'small.' Upon collision, they're set to be destroyed, replaced by a larger object tagged as 'medium.' However, two medium objects spawn instead of just one. Additionally, these new objects appear at the spawn point of the initial small objects, whereas I intend for them to spawn at the exact collision location. How can I achieve that merging effect, similar to the game 2048. What I'm trying to do is a snowball keep growing with each new smaller object added to the mix. Also here is my current object setup:

[sick sky]

begin overlapcan be called twice

However, two medium objects spawn instead of just one

when this happens, is 'col' printed twice ?

[nimble citrus]

yes!

[sick sky]

and i think i understood the main problem

for each small objetcs, this code is called
so this will result in 2 time your code (2 prints and 2 spawned mdeium)

since each collided small object will start overlaping

[nimble citrus]

i see! is there a way to limit it run only for one object? because all the small objects have the same blueprint it2ll keep running it for both of them

[sick sky]

a possible fix would be adding a bool var "did merge"

it is false by default

• before your branch, check if "did merge" is true

• if its true, destroy self

• if its false, check for the tag,

• if the tag is found, you set to true and do your stuff

[gentle urchin]

that wont work

the issue is that they're two instances, and they both collide with each other

so both react to the overlap event

and both have the correct tag

and b oth spawn the new medium

What you could do is when you interact with one of them

you can mark them in some manner

either by a bool or by adding/removing the tag

bool is safer

that way you can use that bool as described above to block the functionality in the cube you're holding

(so the merge happens on the other cube, not currently held by the player)

(welp, you're dropping it , so i guess that wont work)

atleast not directly

[nimble citrus]

yeah! it kinda worked once but never again, on the instance it worked it kept one small object, so i guess it just didn't recognize the collision

[nimble citrus]

yeap in the regular gameplay i won't be holding the objects

i'm thinking of a way to not destroying both of the objects and not spawning new ones but keeping one and make it grow with each additional collision destroying the smaller object in each collision

[gentle urchin]

whoever destroys first wins

just make sure you validate the target first

it should then be marked for destruction

im also not sure why you're using CAC

why not just Actor?

[nimble citrus]

i'm not sure what is CAC honestly 😅 i've been learning UE only for a week at the minute

[gentle urchin]

Child actor component

[nimble citrus]

oh i just draged and dropped the medium object from the content drawer

[gentle urchin]

Really?

thats interesting ..

SpawnActorOfClass is usually what you wanna do,

and destroy self (alternatively Set Lifespan)

[nimble citrus]

got it!

thank you very much to both of you trying to help!! you're too kind

[nimble citrus]

it's working fine for now, i just need to do the math right 😅

now i see the extra branch please ignore that

[gentle urchin]

Ypud probablt want a generic cube actor class

Which have some value to it, directly related to the size

So instead of looking for a tag, you look for a class, and attempt to merge with self

[lofty rapids]

here if the last one was < 0.5, your stuck

[dark drum]

Does anyone know if there's a way to specify the default key value when adding a new entry to a map? I'm wanting to use an int as the key and it defaulting to 0 makes it awkward. :/

[gentle urchin]

Just add entry 0 last

Or does your ocd not allow you?

[dark drum]

I feel attacked. 😛 haha. Having 0 last is what I've been doing but I'd prefer it to be a value less likely to be used.

If I decide to add another, i have to modify the 0 entry first (to a different one) and then re-add it which isn't ideal.

[gentle urchin]

You mod 0 to new, and add new 0 😄

But yes its awkward

Could do it by script

What id do is fake it with more instances

Which you on damage, swaps for a real actor

Yepp

[torpid hearth]

Hi! I'm trying to export a metahuman to my project (using quixel bridge), but this error keeps occurring:

anyone knows how to fix it?

[verbal jungle]

have u tried reconnecting the pin

[lofty rapids]

that value doesn't exist, redo the node

[verbal jungle]

Anyone here with experience with the* InterpToMovement *component?

[south ginkgo]

Perfect! I'll try that out, thank you so much!!

[jaunty solstice]

Blueprint puzzle. Why isn't it possible to simply cut paste functions from one BP to another?
If you can't cut paste, how do you use functions in multiple BPs?

[hoary junco]

so I'm trying to create impossible geometry by teleporting my player around between similar looking corridors using directional teleporters, most of it is working so far but I want the effect to be subtle, like I don't want the player to know they've just been teleported or it breaks the illusion, but whenever my character walks through the teleporter there's this slight jitter in the character's vision as they are teleported, is there a way to get rid of this jitter?

[lofty rapids]

how are you teleporting ?

just setting the position ?

[hoary junco]

yeah, set player position and rotation

or, set actor location and rotation

[lofty rapids]

it's probably loading

that would be my guess

[hoary junco]

well I'm only moving them like 700 units..

[lofty rapids]

hmm

wdym "jitter" ?

[hoary junco]

hold on lemme get a video

[hoary junco]

this is what I mean

you'll see when the teleport occurs

[torpid hearth]

yes, it worked for this BP, but the rest still on error. I didnt change anything in metahuman BP, there's a recent tutorial for unreal 5.3?

[verbal jungle]

then u just need to do this to everywhere else

whatever the Live Link Body Retarget is was changed so the references need to change too

i think there's a "replace reference" functionality somewhere

[torpid hearth]

ok, I'm going to try this, thanks 🙂

[ripe quarry]

The jitter could just be the result of the player teleporting to a location thats not pixel perfect in relation to the corridoor

Then again i'm no expert, still learning day by day

So dont take my words as gospel

[hoary junco]

it should be pixel perfect though, the second corridor is exactly 740 units above the first, and I've told the calculation to preserve the rotation and just add 740 to the Z direction for location so it should be a smooth teleport but idk why the jitter occurs

[lofty rapids]

maybe you teleport a bit high ?

and you drop down real quick ?

[gentle urchin]

Camera/spring arm lag? 😆

[hoary junco]

it's first person so there's no spring arm

[gentle urchin]

Ah ofc

Then the positions gotta be wrong

Print location on tick

[hoary junco]

it shouldn't be, corridor 1 is at Z 900, corridor 2 is at Z 1640, so I have the teleporter take the player's current position then add 740

[gentle urchin]

Altho... it seems its skewed to a side notnjust straight up

[gentle urchin]

If capsule think its colliding tho..

[ripe quarry]

Or maybe lighting is slightly off on the location ur teleporting to, so you could be seeing the switch between different lighting

[gentle urchin]

Try setting movement mode to flying, disable collision, and teleport

See what happens

[hoary junco]

I use an ambient cubemap for the level lighting, it should be consistent throughout the level

[hoary junco]

how would I do this?

[ripe quarry]

I see

I gotta goto work now so i'll give it a think

[gentle urchin]

I assume you use some on overlap ?

[hoary junco]

yeah, on overlap triggers the teleport

[gentle urchin]

So on overlap -> cast to character -> get character movement comp -> set movement mode

And set actor enable collision

Iirc

[lofty rapids]

i would make sure the top part is perfectly lined up as well

just check the maths make sure its correct

[hoary junco]

I found out the issue

fucking motion blur

[gentle urchin]

😆

There we go

Hate it
