blueprint

[odd ember]

well if you dont want my help

feel free to figure it out on your own

[devout dove]

It looks more like your just throwing random things

[odd ember]

lol ok

well good luck then

[devout dove]

you saying map x+ and x- like what?

Can you show me that x+ exists?

[earnest tangle]

jeez at least he's trying :P

[devout dove]

What a kid what ever

[earnest tangle]

try just putting it on the gamepad left stick x-axis

[odd ember]

maybe next time don't insult people trying to help

[earnest tangle]

remove the others

[devout dove]

Yes he is trying but if he doesnt know how it works then he shouldnt be a smartass

[heady saffron]

Hey guys, I am really confused as of why my cast is always failing off of base_pokemon... any ideas?

[devout dove]

I did that zomg

[earnest tangle]

okay can you show me

[odd ember]

have you used breakpoints before?

[earnest tangle]

@devout dove okay, how is the input event set up in your pawn or such?

[heady saffron]

yes...

[devout dove]

simple print out of the axis

[odd ember]

breakpoint the cast node and see what class the active pokemon is

[earnest tangle]

@devout dove try just doing Input Axis Joystick and see what you get from that

[devout dove]

joystick doesnt output anything

[earnest tangle]

can you show how you have it now

[devout dove]

or do you mean the action node?

[heady saffron]

@odd ember well active pokemon is a pawn and base pokemon is a character

[odd ember]

that's your issue

[earnest tangle]

I mean similar to this

you should have an InputAxis Joystick

[heady saffron]

@odd ember but it works in another blueprint lol

[odd ember]

character derives from pawn

but pawn does not derive from character

if you have pokemons that are characters, they may cast succesfully

[devout dove]

Doesnt work

[odd ember]

but it won't cast successfully if they are just pawns and not characters

[earnest tangle]

@devout dove does this pawn actually receive other input events correctly?

[devout dove]

yes i can use my mouse to move it 😄

[heady saffron]

@odd ember but why is it working in another blueprint, its basically the same event I want to happen but in different widgets

[earnest tangle]

what about keyboard events?

[odd ember]

I just told you

it will work if the active pokemon is based on the character class

[devout dove]

yep all works

[odd ember]

it will not work if it is based on the pawn class

[devout dove]

keyboard mouse all works

[earnest tangle]

hm well that's very peculiar... pretty sure it should work like this 🤔 have you tried any of the buttons for actions? Eg. see which button lights up as 1 in the windows game controller menu and see if that triggers anything in UE

[heady saffron]

@odd ember hmm this becomes an issue cause i need it to cast to a pawn, also I am calling the exact same function but it is working in another blueprint, the active pokemon is still a pawn and it works there.

[odd ember]

show me the code where it works

[odd ember]

put a breakpoint there

and see if it's a pawn too

[heady saffron]

it is, its also the variable type i set it as.

[odd ember]

is this true for all your pokemons?

[heady saffron]

Well all pokemon are characters, and base pokemon is the parent class of them

[odd ember]

because a pawn should not be able to be cast to a character, unless it is a character

so a character can be a pawn, but a pawn is not necessarily a character

[heady saffron]

yeah...

[odd ember]

then try making the active pokemon class a character instead

and see what error you get

[heady saffron]

@odd ember base pokemon is already a character

[odd ember]

not base pokemon

active pokemon

[heady saffron]

Its not neccessarily an error that i am getting when i do that,

[odd ember]

you should get an error because now the cast can't fail

[heady saffron]

I cant plug that in, which i need

[odd ember]

ok so pokemon in the world

isn't a character

that's your issue

[heady saffron]

lol can we vc real quick?

you will see what i mean

[odd ember]

nah I dont do vc, but post your error

[heady saffron]

Ok well if i change it, everything stops working cause im using nodes such as spawn ai from class which will now not be able to connect to pokemon in the world, also, when pokemon in the world was a pawn, it was working for the other widget

[odd ember]

can you show me your spawn node and which class you are spawning?

[odd ember]

again, you do understand that some pawns, that are also characters, WILL pass the cast node

but some pawns, that are not characters, will not

[odd ember]

what class is your pawn class?

just to be certain

because I see the issue already

[heady saffron]

well i just changed it to character

[odd ember]

the purple class

the purple wire going down from the node

[heady saffron]

its set to a break info

which is pokemon class

[odd ember]

and pokemon class has which parent class?

[heady saffron]

base pokemon

[odd ember]

ah

I see

ok

in that screenshot

swap the cast node and the pokemon in the world node

[heady saffron]

still failing

[odd ember]

show me

[heady saffron]

well the error was fixed, but the original issue is still failing

im able to plug in pokemon in world to active pokemon now

but the cast to base pokemon is still failing

[odd ember]

it might be the spawn AI node cannot spawn characters then

and instead spawns a default pawn or something

which then doesn't convert properly

[heady saffron]

well its not that one that isnt working

that one, in the original bp that i showed u

[devout dove]

FOUND THE SOLUTION!
https://docs.unrealengine.com/4.27/en-US/InteractiveExperiences/Input/RawInput/

[earnest tangle]

Oh nice, I guess it wasn't an XInput device then

Good to know that exists in case I ever run into this :)

[devout dove]

And CE wont even see it hahaha feelsBatman

[earnest tangle]

his loss I guess lol

[devout dove]

I have all axis now the mini stick on top and the big one including the Z rotation

[odd ember]

try to make the active pokemon of the base pokemon class

[earnest tangle]

sweeneymons

[odd ember]

C&Ds aside, I'm pretty sure the root problem comes down to how SpawnAIFromClass handles pawn spawning

it doesn't seem to be the same as spawn actor from class

[earnest tangle]

I noticed you actually can call that function in some contexts where you can't call the regular spawn actor node which is a bit peculiar :D

it looks like SpawnAIFromClass just spawns the actor fairly normally so not sure if there'd be a difference because of that

[odd ember]

I have no visibility on the full project, but I'm pretty sure it's some issue with a pawn somewhere not being able to be a character

I don't know if SpawnAI can spawn characters

or how it works with that

[indigo bough]

I've got a function which gets the nearest component of another actor to my player. I'd like to find the 4 nearest, rather than just the nearest. Is there a way to do this? The components in question are in a grid configuration. Eventually the plan is to compare distances to get a weighted average of a float value from each of these 4 grid cells, based on how near the centre of the 4 nearest cells the player happens to be.

[earnest tangle]

it requires the class to be a pawn, that's all

[odd ember]

so then the cast shouldn't fail

[earnest tangle]

I didn't follow the full conversation but I guess it's possible it return null from the spawn because of a collision or something

[odd ember]

perhaps

[odd ember]

you'll have to iterate over them

[icy dragon]

This
||He did mention about getting the pokemon asset from an asset rip hub, so that's one more C&D factor, but I digress||

[indigo bough]

Would I have to iterate 4 times? How would I ensure I'm not getting the nearest the next times, remove it from the original array before iterating again?

[odd ember]

you could place the ones already found into a new array that you'll have to return anyway

if they exist in the array already, they have been accounted for

[indigo bough]

Ahh okay, good idea. Thanks!

[plain berry]

does anyone know why this code doesn't work in construction script?

But in an editor callable function it works fine?

trying to get the spline point to start at the billboard position

Contstruction script keeps it here

but BP callable function puts it in the correct place on the billboard

[odd ember]

construction script is called every time you update the actor in any way

[plain berry]

I'm aware, that's not the problem

[odd ember]

are you sure?

[plain berry]

As another example

So when it's caching the data of a separate world BP, the spotlight will rotate to 'look' at the actor

but with a component, it will not 'look' at it when the BP is moved

Because moving the actor with the code counts as 'updating' the construction script

[indigo bough]

I just realised, if I just limit which components I add to the original array to ones with a distance equal or less than the grid square size, it'll only grab the nearest 3-4 options anyway. 🙂

[plain berry]

Also, sorry, response was pretty blunt. Thank you for offering a possible solution!

It's just something I've already ruled out

Unless I'm deeply misunderstanding the way construction scripts are called to update

[odd ember]

in your second example, you can double check if the root component is actually valid first

[plain berry]

Which is always a possibility!

[odd ember]

there might not be an actor in world

of that type

or even better, create at the bare minimum a hard reference for an object that you then check against

[plain berry]

Sorry for confusion: the BP Focus Light actor in the world is the one that works

It's the local component on the actor to be updated that doesn't work

[odd ember]

sure, I'm just saying that it will still be error prone if you don't check for validity

[plain berry]

I know, it's just easier to show simpler examples online without checks

[odd ember]

is it exactly the same logic you have in the update function?

can you show me the update function?

[plain berry]

Yep, exactly the same

literally copypasted

I wonder if it's an order of operations thing

[odd ember]

try calling update from construction script

instead of copy pasting the logic

[plain berry]

Where the location of the local component is just not being cached when construction script runs

excellent idea trying that now

nada

No change

[odd ember]

so possibly your logic just doesn't work with how construction script updates

which perhaps is correct

do you change your spline and then press update?

[plain berry]

Well this is interesting. It seems like the construction script just doesn't cache the value of the component at all

[odd ember]

okay am I understand you correctly in that you're using the billboard to create new spline points?

[plain berry]

In the context of the problem, the only thing that really matters is getting the construction script to respond to the location of its own component during construction

But essentially yes

[odd ember]

not sure if it's relevant but you might be able to work with it somehow: if you select spline points, you can alt extrude new spline points using the pivot

[plain berry]

In this case, the spline is totally deleted and remade

[odd ember]

and I think that's the issue

[plain berry]

Nah, it's a caching issue.

[odd ember]

my other suggestion would be to make a separate actor hard ref that you then use to model your spline after

however how you would put down points when its continuous is beyond me

[plain berry]

Nah, I'm building an environment spline that responds to gravity during construction and will later be baked down into a static mesh

[odd ember]

isn't this what the cable component already does

[plain berry]

There it is

Relative location DOES NOT get cached during construction script

world location does

Cable component is an option, but it's also very self-contained and I'm too lazy to go into C++ and mess around with the plugin for what I need to do later

@odd ember Thanks for helping me out! I've been banging my head against the wall all morning!

[odd ember]

I did nothing though

[plain berry]

Nah, you pointed out debugging stuff I should have thought about but didn't

[odd ember]

well alright, glad it worked out

[onyx violet]

anyone have experience with the localization dashboard? I can't seem to get it working

i've selected different languages, gathered the text, and compiled translations, but when I use the node to set current culture, nothing happens

[odd ember]

I haven't, but perhaps MathewW would know given he's made at least one video on that subject

I think he's only hovering around the #ue4-general channel though

[onyx violet]

ok i will check it out thank you

[plain berry]

Update: NOPE. This was just caching the actor location. Component location is always 0 locally until after construction script

https://tenor.com/view/sad-girl-gif-8382180

dangit

[odd ember]

welp

I mean you could assign or spawn another actor that carries the same logic

for the spline

singleton the actor on construction script

[plain berry]

True. Just feels kinda gross from a user-end.

[odd ember]

idk, seems like a decent built in solution

[plain berry]

Oh like spawn an actor during construction script, then delete?

[odd ember]

yep

[plain berry]

dirty af

I love it 😄

[odd ember]

nah editor only actor

chugs along

deletes at the end of construction script or persists through singleton (but destroys during begin play or such like)

[plain berry]

I love editor-only stuff because I almost never have to justify performance.

[odd ember]

yeah I've done a few really nice extensions

the biggest issue I'm facing is no interface for adding editor only hotkeys

which is limiting when you have functions that require viewport focus

not to mention they are a workflow impediment

[plain berry]

At my last studio we coded editor hotkeys with C++, but the editor customization side of UE4 in engine is pretty limited. Like how you can't inherit editor utility widgets from C++ or it loses all unique functionality.

The downside of doing niche stuff I guess

[plain berry]

Hang on. I'm 100% certain this is possible. Because it's been done before.

[odd ember]

I'd love to say it's not niche

but perhaps I am wrong

well if you do have the scoop

hit me up

[plain berry]

Are you assigning the hotkeys in project settings or editor preferences?

[odd ember]

I'm not assigning the hotkeys

I can't bind them to a custom event

or even an editor widget button

[plain berry]

Are you doing it with BP or C++?

[odd ember]

this is purely BP but if there's a cpp solution then I'm happy to hear of it

I've extended UDevSettings with great success

[plain berry]

one moment lemme check

[odd ember]

by the same token, if there's some cpp function way of offering a TArray<FName> as a drop down for functions that you might know of, I'm all ears

those two things are my outstanding gripes with editor UI

[plain berry]

Wdym by drop down? Like passing an array of FNames into a function?

[odd ember]

something like this spiffy creature

[plain berry]

Oh like an enum?

[odd ember]

yeah except it's an FName

[plain berry]

hmmm lemme think

[odd ember]

I did check that node in the editor code, but it's messy. I've since heard from an epic programmer that it is possible for FName var on classes (e.g. so they show up in the details panel of a BP class), but not as function parameters

[plain berry]

Yeah. I'd think the best way to do that would be the input be an enum, then use Enum to Name in the function itself

[odd ember]

the issue is that it doesn't allow for dynamic input then

which is the crucial part of using FNames

if it was static then yeah Enums all the way

[plain berry]

Wouldn't a dropdown require static input anyway?

[odd ember]

but the fact that you can do it for vars on classes dynamically got me hyped

nope

in fact that drop down I showed you updates dynamically based on a data table

dynamic during editor time to be clear

once at runtime none of this matters

[plain berry]

Ahhh I see. I could think of a few solutions, but they would all contradict the idea of it being an ease of use issue in the first place.

[odd ember]

fair enough

[plain berry]

Sorry to say I can't find any notes on how we did the editor hotkey, but I can check tonight after work. Mind if I DM you if I find it?

[odd ember]

sure

[burnt abyss]

is there a way to detect if the player does not have the game window focused?

[hardy fable]

Class variable drop downs are generated by providing an Options functions, eg:

UPROPERTY(EditAnywhere, meta = (Options = "MyOptionsFunc") 
Fname MyName;

UFUNCTION() 
TArray<FName> MyOptionsFunc();

AFAIK, the only way to get function drop downs is via pin customization classes and editor shinaniganery, which I have done a bit of to know how tedious it is. Lots of boilerplate involved and copying what the engine does since there are no docs on the topic.

"most direct" way is to make a struct that pretends its a fname pin, by recolorering itself to the fname color, and overriding it to accept fname connections. And then making a details customization and a pin customization that generate drop downs. The code for how game play tags act is an example of pin customized dropdowns

[odd ember]

yeah, this is what I know as well. but I cannot get the same functionality for a function parameter on a BP node

ah I see

[hardy fable]

Yes that would have to be done with a customized blueprintable struct

[odd ember]

perhaps I can just hijack gameplay tags for this purpose if the ability for them is already setup

[hardy fable]

Possible. Gameplay tags are very very usefull

They are basically fancy fnames already

[odd ember]

in my case they'd just be stand ins for names of structs at editor time so I would be able to pick between them

but, good to know

I will definitely explore this

thanks

[hardy fable]

All that customization requires pretty good slate knowledge so if you aren't good with slate your pretty f'ed anyway

[tight schooner]

I looked into this myself before and found a solution in "Rama's Victory Blueprint Library" which has a pure function called Client Window Is Foreground.

You can run that pure function on e.g. Player Controller tick to detect when the window is unfocused

https://github.com/EverNewJoy/VictoryPlugin

[burnt abyss]

Thanks, I'll check this out now

[tight schooner]

can't comment on the rest of that plugin cuz I kinda lifted that one function and put it in my own C++ function library (which is basically the beginning and end of my C++ abilities, lol)

[burnt abyss]

Worked, thanks for the help lol

[mystic mist]

What is the best way to set up a blueprint for triggering all lights in the room? or I guess blueprint classes
Ive got a bunch of blueprints I want to trigger all at once, for the most part the same.
I know you can build a level and then save that as a blueprint and use it on another map, But I dont want to have to lay them all out at once and then make a blueprint from there, I'd like to be able to move them around.

[burnt abyss]

you could make all of the lights their own BP, then in your level blueprint (or wherever you want to trigger from) you can get all actors of class and then get a for each loop, which will then run the code on every specific actor in that level

in this i set the speed but you could do the same with visibility/intensity and it should still work the same

[mystic mist]

hmm hmm I see I see. I will try and update. Thank you!

[sonic crescent]

hi! I am spawing mesh in my level. A mesh is not display correctly.
Doing a "Set Actor Hide in Game" On and "Set Actor Hide in Game" OFF seems to fix it.
So it a refresh problem.
Any way to do a better refresh than my "Set Actor Hide in Game" hack?

[burnt abyss]

when you say the mesh isn't displayed correctly, what do you mean by this?

like is the lighting messed up?

[sonic crescent]

I'm doing a scale -1 of somes meshs. Most of them display correctly but sometimes Meshs are displayed with all normals inverted (polygons flipped)

I'm doing my scale into a function. So i can't put a delay to let them display properly.

Btw, i have fixed my problem but saving the actor in Hide in Game. And Set it to "Hide in Game" diabled at the end of its display routine.

[mystic mist]

@burnt abyss should I remove the toggle visibility from the lights Blueprint and move that to the Level blueprint For each Loop node?

[burnt abyss]

the get all actors of class bit should be in the level blueprint, along with the for each loop

[mystic mist]

ok so here where I guess I am unsure. Does this set up from my lights:

need to go here:

?

[tight schooner]

I haven't played with level streaming so I don't know the ins & outs of that. But generally speaking if you're trying to associate a light switch with a bunch of individual lights, I suppose there are a few ways to go about it.

One is to have a public (or "exposed" or "instanced editable") array variable on the light switch and fill the array with the spawned lights; unfortunately this would only work for things that are already spawned into the level, so idk if it'd work with level streaming.

Another approach is to tag the lights (with actor tags), and have a Name variable on your light switch which it uses to Get All Actors with Tag to find the lights it's associated with.

To do it in reverse, your lights can find the light switch via an actor tag (if not a direct actor reference variable), and then the lights bind to an Event Dispatcher on the light switch. In this scenario, the lights communicate with the switch instead of vice versa.

[burnt abyss]

you could make an event in the light BP, and then run it through the for each loop so it runs for all of the lights

[tight schooner]

In structuring the actual communication, I would think it'd be best if the switch, which is sort-of acting as the manager BP, knew the least about the lights. So it'd just call a function/event/dispatcher that tells the light whether the power is flipping on or off (i.e. one boolean variable), and then the light BP has its own script for how to turn off exactly

If all the lights and other electrical devices share a common parent class, then you can have a variety of devices that respond differently to being activated/deactivated by a switch

[mystic mist]

Ok Ive got it figured out.

I lied I can get it to turn on working on getting it to turn off haha

[burnt abyss]

lol

[mystic mist]

it worked before with the flip flop so it should work this time

ok... weird. now some are turning on while others turn off.

and vice versa

I know Im doing something wrong but I dont know what

do I need to swap the For each loop and the flip flop?

[mystic mist]

ok so its something to do with the fact that its calling them separately, so the materials are constantly flipping

so I need to combine the two targets into one node

how would I go about that?

wait a second

omg

I need a static mesh

[spark steppe]

you go over all lamps, and flip on the 2nd

no

you need to fix your "logic"

[mystic mist]

ok but I dont know what to fix

[spark steppe]

you want them to flicker all at the same time?

[mystic mist]

turn on when clicked, then turn off when clicked again

[spark steppe]

then put the flip flop before the for loop

[mystic mist]

here it is cleaned up

inbetween for and get all actor?

[spark steppe]

yes

and use a branch and the output of the flipflop on the loop body to switch between the two modes

both execution outputs of the flipflop go to the same for loop

[mystic mist]

Like this? It works haha

[spark steppe]

kinda

not what i meant, but that works, too

[mystic mist]

oh wait hang on I got you

oh no wait that wont work

because I can only connect the loop body to one material at a time

[spark steppe]

thats why you put a branch between

which uses the bool output from the flipflop to decide which way to go

[mystic mist]

oh ok like this?

[spark steppe]

yes, just connect the flipflop's "is A" to the branch condition input

[mystic mist]

oh swap for and branch?

[spark steppe]

no

just connect the two red circles xD

[mystic mist]

GOT IT

sorry Im new to Visual Scripting

Honestly if this was straight code this would have been figured out hours ago

[spark steppe]

(x) doubt xD

[mystic mist]

the logic works when I see it (thus the visual). But its getting it visualized. thats hard.

well thank you for the help

and everyone else

its been a pleasure

Media player for wmf video file source is messing up and not playing properly after I set Rate to anything higher than 2 and then try to go back to 1.0

This is with mp4 files

I haven't tried precaching the entire video yet to see if that fixes it but some videos are over 1 GB so I want to avoid that. Maybe I will just seek ahead a few seconds on a timer instead of changing the play rate. Any idea why it acts broken or how to fix that with the play rate? It only goes back to normal if i reopen the source.

How can I use this node anyone knows.

Please help.

Or share a documentation. Please help

[burnt orbit]

Really tried to do this, but I dont believe I quite understand how to get rid of the widget after pressing the respawn button.

[icy dragon]

WTF even is this? Why it's so important to you?

[chrome fractal]

I want to do a documentation because I have to handover my project to another dev

[icy dragon]

Why not adding a comment?
Hold C and click anywhere in the graph, and you're off.

[chrome fractal]

Actually its for connecting documentations through links.

[burnt orbit]

I have no clue. Here is the code where the widget is being pulled from. Its in my character EventGraph. perhaps im doing something wrong

[chrome fractal]

I just want to know how can I use this

[burnt orbit]

I am able to respawn from clicking the button tho

[icy dragon]

I suppose that is UDN exclusive? I know there are some minor things UDN usergroup (AAA licencees) get that more public users don't.
Though I don't see how this is not a viable solution

[dawn gazelle]

It also looks like the Documentation node is driven by external files stored in /Engine/Documentation/Source/Shared/GraphNodes/Blueprint if you're using the default "link" value.

[icy dragon]

Actually scratch that UDN exclusivity part, forgive my ignorance lol

[chrome fractal]

How can I add my documentation in that excerpt?

Please Guide

[dawn gazelle]

Sorry, I'm not entirely sure. You'd probably have to create a file at the defined path - if you look at the example .udn files you can see how they work.

[chrome fractal]

ok sure

thanks for the reply you both

[icy dragon]

It seems like this UDN isn't stand for Unreal Development Network, which is, let's say the VIP of the Unreal Engine licencees.

Hi! not sure if this is the right place to ask but does anyone know where to get the set this up in 4.27. I know the set level viewport camera info node was moved to the unreal subsystem but no idea how to access it. I am a noob😅 this is for a widget to cycle cameras

[grave relic]

Anyone here that can help me find the right node. I have an ai that is just suppose to stand still, so i have disabled movement. But later i want them to walk around, but there is no node that is enable movment

[gentle urchin]

Isnt there some kill brain function for it, if you're running BT ?

[grave relic]

Yeah, tried it by setting it to walking or navmesh walking but couldnt get it to work

[gentle urchin]

^sounds like a better solution

[paper galleon]

I'm not sure how you're moving the AI but you probably need to restart the move to task. But Lorash's approach seems better

you can often improve the accuracy if you have a limited dictionary of words you need it to detect

[paper galleon]

$5 less

[trim matrix]

that wouldnt be an issue

[icy dragon]

I remember how painful it was to use Windows Vista's speech recognition thingie, even as a kid.

[earnest tangle]

I had the Cortana function in Win10 enabled just for fun but I never used it

Then I randomly clicked it by accident a couple weeks ago... and it just told me cortana is not available in my region

so uhh... I guess they did a 180 on that feature then?

:D

There's some speech apis in windows tho but not sure if it's offline, or speech to text

[spark steppe]

i remember the first speech2text softwares...

probably one of the reasons i can type pretty quick now 😄

you had to train them and they still where awkward slow and pretty CPU intense

[warm sparrow]

Really new user here, would anyone know a simple way to make my Third Person Character face somewhere he impacts? So for example he hits a wall (Which is the breakhit in my screenshot) and then make him face that wall? Any help is appreciated :)

[paper galleon]

Find look at rotation node.

The impact point as the target and character location as the location. Use only the yaw value of the rotation obtained

[warm sparrow]

Thank you so much :)

[paper galleon]

You should be using the set actor rotation node for the solution I gave. I think? Test the two nodes and see which works

[warm sparrow]

Yeah, I realised as I was implementing your solution that I was using add rotation, guess I used it for one of my attempts and forgot to replace it for any others, which could be why they failed, but your one works fine :)

[paper galleon]

great

[gentle urchin]

Not sure if this is a question for another channel but; In an RTS without terrain modification options, isn't it sensible to keep the NAV dynamic for modifiers only (not fully dynamic) ?

^

[faint pasture]

If it works it works. Worry about it if performance is bad, but that should be fine

[gentle urchin]

^true. thanks

[dim robin]

sorry i don't know how and where to post this: is there any way to know if a function is more "expensive" than others?

[paper galleon]

In terms of performance? you can use the performance profiler. Check the documentation on how to use it.

[paper galleon]

But I suspect you don't need this information. It might be premature optimization

[dim robin]

I might need it now because for the first time I have a severe bug (pawn disappearing) and it might be because of performance.

[paper galleon]

I highly doubt that. Do you have a specific function in mind? It would help to show the code

[brittle plinth]

Hey guys, Is there a possibility to step on a trigger box and activate another one which is invisible or doesn't work until you step on the first one ?

[gentle urchin]

They can be set up however you like

So yes, it is possible for one trigger box to "activate" another triggerbox

[brittle plinth]

how would that work ?

[odd ember]

by activating one when you're colliding with the other?

[brittle plinth]

yeah

I've made it

like this

but it does not activate the first one

I want it to be active once I step up on it

[odd ember]

you've just set it to visible

for a root component even

that doesn't do anything

you probably want to use SetCollision or whtever it's called

[brittle plinth]

ok, then how could I activate it otherwise ?

[odd ember]

visibility is not the same as functionality

just because something is visible does not mean it's functional. and likewise, just because something is invisible does not mean it's not functional

set collision, or whatever it is called should have a few different options

[brittle plinth]

yeah you are right about the visibility

[odd ember]

you're probably looking at overlaps judging from the screenshot, so query only collision

[brittle plinth]

yeah so let me explain in detail

I have a room with 2 triggerboxes , One is set when you enter the room and I want that one to be disabled and the other one in the center of the room. When you step on the one in the middle you activate the one at the door, so when you overlap the one on the door ,it activates the events programmed in the master blueprint

does that make sense?

[odd ember]

IMO instead of explaining what you want your implementation to be, a better way would be to give the concrete case of your design problem or the experience you want to design for

I can read and understand what you're saying, but it doesn't make sense in the greater scope of things.

[brittle plinth]

So, basically , the short version,

You overlap the 1st triggerbox and it does not do nothing , unless you go to triggerbox 2 and then back to 1

[odd ember]

if your problem is just getting the other plate to activate, I've given you the solution for that

[brittle plinth]

yeap

[trim matrix]

I've followed a persons tutorial for opening something, I've followed it 1 to 1 and I don't understand it and I haven't found a fix, is anyone able to help me?

https://www.youtube.com/watch?v=IMCS-j9my8s

https://gyazo.com/ceb9bf0fb3bc357f14edb39729c4b317.gif

I am pulling my hair out

[odd ember]

I don't think anyone can look through a video of a tutorial that works and tell you why your implementation doesn't work without you showing your code

[trim matrix]

Well that's why Im asking for help, if they would want to, I would show it

[odd ember]

don't ask to ask

just post your problem

if someone can answer, they probably will

sometimes immediately, sometimes delayed

[icy dragon]

https://www.dontasktoask.com

[brittle plinth]

it does not with SetCollision

:/

i think i need to find generate overlap events to be set ON

maybe like this ?

But I don't know what to connect on the target

[odd ember]

you have to setup your collision channels to be correct as well

[odd ember]

I still don't know what your concrete problem is

[trim matrix]

Okay so in the tutorial, when he holds down "E" the "E" widget bar will fill up, like in most games
However mine does not and I can't find the issue

[odd ember]

by E you mean your interact input?

[wary tinsel]

Hey guys I need to get a random int between 0-5 BUT only one time. This means that if I get int = 2 the next time I call the function he should never consider int 2 and go random on the remaining numbers. Is it possible to do this without doing 3000 branches? thanks

[trim matrix]

Yes

[odd ember]

I don't understand your case but there is a node called GetRandomIntInRange

[earnest tangle]

If you want the valid numbers to only be selected once, put them in an array

eg. validNumbers = [0,1,2,3,4,5], then on each time you pick one at random from array, and remove it from the array

[wary tinsel]

I did an array

but if I remove the index 3 the next time the index 3 will be following number

it's kind of tricky 😦

[earnest tangle]

Why?

just use the random from array node

[odd ember]

I don't have much time right now, but I would suggest using breakpoints on the interact event to figure out what exactly happens when you go through it

it may be that your arent overlapping any actors for instance

[trim matrix]

I've tried using breapoints and they dont exactly help me

[dim robin]

hard to ask question (I'll try to make it more schematic as I can to make it easier to understand):

• I have a pawn. this pawn is made by a sphere (physics simulated), springarm, camera (and a sphere collision slightly bigger than the sphere itself).
• as soon as the game start, of course the sphere will fall on the floor because of gravity.
• I have an input which adds an impulse to the sphere (basically it shoots it) so the sphere might be on air at some point, ready to fall down again.
  i need to be able to tell if the sphere is in the air or if it's touching anything: how would you achieve this?

[spark steppe]

line traces

or maybe by checking the z velocity

[atomic salmon]

@wary tinselwhen you remove an item from an array while looping through it, you should do it in reverse order

if this is how you are doing it.

@dim robinlucky you your pawn is a sphere 😉 https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/Collision/SphereOverlapActors/

[dim robin]

OMG!!!!

[atomic salmon]

make sure the actors you want to detect are set to generate overlap events

[mild jacinth]

hi, how can i make it so that the checkpoint sound plays once, but does not play when you get to the same checkpoint again?

its most likely something really easy but im having a brain fart if you can call it that

i dont really want to make separate checkpoint blueprints for each checkpoint

[odd ember]

are you sure? they will tell you if there are overlapping actors if you hover over the array

[odd ember]

Ideally before you activate the checkpoint, you make a check (hehe) on whether it's already the current checkpoint. if it is, do nothing

[trim matrix]

Hello, pliz help me im close to crying, so im making a 1 person shooter and i have a fire input on LMB. The game is already on steam and some of the players expirence a strange bug that not all of their presses are registered by the game, for example press 20 times and 17 of them fires and 3 does nothing, the OnPressEvent does not even exec
This is the function, nothing special here
Any ideas ?

[spark steppe]

https://tenor.com/view/dibo-the-gift-dragon-cro-magnifying-glass-looking-checking-gif-17580815

can't read anything on that screenshot

[brazen pike]

you can upload blueprints to blueprintue dot com

much easier to read

[gentle urchin]

plus this doesn't show anything inside the start shooting event

whatever magic might be going on there...

[trim matrix]

Idk where to find that

[ripe rose]

https://i.imgur.com/K8VanCU.png

questionmark

[odd ember]

if you breakpoint and step forward you'll get to that point every time you press the interact button?

[sonic crescent]

.... First, if i unrestand right, it seems that i must do that in a Construction Script, that's the base, right? (and not in the Begin Event like it is)

[trim matrix]

I breakpoint here

[spark steppe]

where is that array defined?

[trim matrix]

But it gives me no information

[ripe rose]

it's a local variable in this function

[odd ember]

yeah because that's not where I said to breakpoint lol

remove that breakpoint, put it on your InputAction Interact event

[ripe rose]

ok i just created a new local variable that is also an array of transforms and replaced the old one and it works now

lol

https://i.imgur.com/ZVmMDzN.png

https://i.imgur.com/vTRgwWQ.png

[spark steppe]

you probably checked "blueprint read only" in the other variables details

[ripe rose]

i definitely didn't

i literally just made it like 2 minutes ago

rofl

[spark steppe]

doublecheck!?

[ripe rose]

where even is that

[spark steppe]

if you click the variable, theres a checkbox in the details

[ripe rose]

https://i.imgur.com/n4G4jp2.png

[spark steppe]

might have to open the advanced tab

[trim matrix]

Im having a really hard time trying to find that inputaction interact

[odd ember]

it was on your first screenshot?!

I can't help you find your code if you can't find it yourself

[trim matrix]

Ah I see

I was looking in different blueprints

Okay now what

[odd ember]

play the game

try to interact

[trim matrix]

I did that, it stopped there but it gives me no information

[spark steppe]

@carmine bay did you promote the array to a local variable from the function output?

[odd ember]

use the button up top that says "step over"

[spark steppe]

then it may have inherited settings of the function return value, which may be read only

[odd ember]

or "step into"

[spark steppe]

but idk, just guessing. and you solved it by now

[trim matrix]

It brings me to the branch

[ripe rose]

well i instigated the problem by copying code from somewhere else cus i'm refactoring my code, so yeah i hit the "create local variable" button. but i don't know why it made it blueprint readonly or whatever. i'm not using it any differently from how i was using the variable originally

[odd ember]

if you hover over each pin, you can see what the value of that pin is currently

as it is being executed

[ripe rose]

in the future i'll just create each variable fresh

i guess

[odd ember]

that should help you find out why it is happening

[trim matrix]

Before I do anything, what is a "pin"

[ripe rose]

https://i.imgur.com/lJMeyJn.png

risky move i guess

[odd ember]

a pin is the end point of wires

though if you're this new, I'd suggest looking up some tutorials to familiarize yourself with the UI and terminology

this is double work for me trying to explain what everything is

[trim matrix]

I appreciate all the help

[trim matrix]

but the Fire event does not "Fire XD" thats the problem

[gentle urchin]

Are you sure that the issue is externally, and not an internal issue?

The logic you've showed doesn't seem horribly setup, or somehow blocking it from firing

[odd ember]

it does seem a bit suspect that there is a "stop shooting"

one would have thought that the shooting would stop automatically

[gentle urchin]

Could be internal auto fire

dont really know without more info

[trim matrix]

I've been using breakpoints and I've fixed the errors that have been occuring but it still doesn't fill

[valid bolt]

Anyone know how to add the textures to the 3d model?

[brazen pike]

If you have the texture, select it in the top right of that page, where it says "Material". Also probably a better question for #graphics

[odd ember]

you should be able to see what is going and why it doesn't work inside of that event

[trim matrix]

I figured it out, I named something wrong when it was trying to call a certain thing, so it wasn't being called at all
But the breakpoints didn't tell me the issue which was annoying, but I got it to work

Thanks for the help! It means a lot

[odd ember]

breakpoints aren't magic, but they will tell you why something doesn't work at runtime

usually

[trim matrix]

I have run into a new issue
Whenever the widget is in radius, it starts up automatically without pressing the "E" key

[odd ember]

I don't know what that means

can you show me?

[trim matrix]

One sec

https://gyazo.com/82c0b081c06fdabee79afa87003243f8.gif

[odd ember]

if it's not happening when you press a button, it's not related to the input event

it may be related to the overlap of the actor

which would make sense

[trim matrix]

So what exactly would I do

[violet flax]

@trim matrix
Can you show us your blueprint part using this
https://blueprintue.com/

Mark your Nodes in your blueprint and press ctrl+C and past them in the grey box.
And share the linkl
Can't read the one you uploaded here.

[trim matrix]

https://blueprintue.com/blueprint/tzy65gg3/

[odd ember]

look at the place where you have created the overlaps for the actors you want to interact with

[violet flax]

I have a question.
I'm using PlayerState to spawn some things for each player based on if they are the "host" or "joined" and make a array with the information of the actors created.
Inside my "PlayerController" i access both Arrays but it says one is empty. Inside PlayerState both are filled. Anyone knows why?

[odd ember]

probably related to #multiplayer

[violet flax]

yes

[odd ember]

so... that's where I would ask that question

[trim matrix]

Now my widget wont show up at all

[odd ember]

where is the actor that propagates the widget?

[trim matrix]

It would be the event tick right?

[odd ember]

actor

you have to find the right actor

it's not all in the same BP

[trim matrix]

I forgot what an actor was

[odd ember]

I'd recommend keeping a reference sheet for these things then

it's much harder to help when every time I have to re explain elementary concepts. an actor is the entity that exists in world, that has a BP on it

[trim matrix]

So the circle then right?

[odd ember]

an actor is the entire thing

again, look up some basic reference please

and you're looking for the actor in particular, that has that widget attached to it

[trim matrix]

Oh, the desk is what the widget is attached to because that's where it shows up

[odd ember]

cool, so look inside the desk's BP

[trim matrix]

I dont see a problem inside it, all I did was reimport my mesh and now it wont show up

[odd ember]

just because you don't see it doesn't mean it isn't there

if the widget is inside the desk actor, then the problem is either inside the desk actor itself, or the widget itself

so first we'll want to check the desk

then we'll check the widget

[trim matrix]

This is my setup of the visibility of the widget, I added breakpoints and tested it and it seemed to work fine

[odd ember]

I don't know what happens inside of that macro

but where you need to look is where you spawn the widget, or on the desk's tick function

[trim matrix]

macro

[odd ember]

ok

check where you spawn the widget inside the desk. if it's not spawned, and is part of a component

then we'll have to look inside the widget

[trim matrix]

The widget location was the problem
Since I reimported my mesh, the mesh moved but not the widget so I have to relocate it

and now my widget wont work at all, time to figure out some stuff

[tawdry surge]

Anyone know what could cause this?
I'm trying to move the player along a spline and it offsets hard

[gentle urchin]

The same effect is achieved with a "not" node for the boolean

[gentle urchin]

Gotta show some code

[trim matrix]

https://gyazo.com/350d539aaf770f2814a31ae990e93a2a.gif

E key still doesn't do anything
I fixed it earlier a different way, my fix is currently in play and that means something else is wrong

[odd ember]

breakpoint your inputAction interact event

[trim matrix]

The red lines mean it's working right?

[odd ember]

what red lines

[odd ember]

that's how far it manages to execute, yes

[trim matrix]

Alright well after that last node it goes back to the beginner, so I assume that this BP is fine?

[odd ember]

but it is moot when using breakpoints as they only stop if they are being executed through

[trim matrix]

Oh

[odd ember]

never assume

[trim matrix]

So the error can still occur even if being exocuted

[odd ember]

yep

[trim matrix]

I see

[odd ember]

the error can be reading of values

or not reading of correct values

it can be any number of things

in this case, your array seems suspicious

so I would take a look at that

and if that works, then look at the OnInteractionBegin function/event

[trim matrix]

On Interaction Begin is just an interface and the message has nothing in it

And this is my array

[odd ember]

that's just the for loop. not your array. and the interface function may have everything to do with it, since it controls what happens when you interact with that item

breakpoint on the for loop node

or foreach node

or whatever it is

[trim matrix]

Alright so the array works

[odd ember]

then the only thing left is that interaction function

so you'll have to take a look the actor you are interacting with again

and see what's inside that function

[tight schooner]

Hard to say without seeing the BP but it could be a local/world thing. Check that parameter on your Get Transform Along Spline node.

[tawdry surge]

That's what I was thinking. Im probably getting local spline coords and setting them in world

[gentle urchin]

If it is, it would worsen the further from 0,0,0 world you got i think

[trim matrix]

Tested this and it works pretty normally, it looks like it's looping back around to the widget

[tawdry surge]

I'm waiting for someone to vacate my chair so I can check

[thorn ermine]

Is it a cat? 😆

[tawdry surge]

No it's an oblivious person jabbing on there phone instead of finishing the email they're supposed to be sending

[trim matrix]

Comes to here inside the widget

[tawdry surge]

Yeah I had my get transform at distance along spline node set to local space.
World space and all good now

Ur editing a copy

And it will work

Almost every day :p

wdym by every day?

u mean ppl have issues with this?

Its a common issue, yes

[wet palm]

so how i solve it

let me read the soultion above wait

[gentle urchin]

Change the get node

[wet palm]

ok

get node?

i change it to what

[gentle urchin]

Get (by ref)

Instead of get(by copy)

[wet palm]

ok!

shit lol

it is there

now it should work

how can i miss such thing!

[gentle urchin]

I mean, i dont know the rest of the logic , but that part should work yes^^

Its easy to miss

[wet palm]

amazing!

yea easy to miss

[gentle urchin]

Circle pin vs diamond pin

Diamond requires a reference

[wet palm]

yeah!

i noticed that also i swear

but i thought if the wires

[gentle urchin]

So.. diamond for diamond 😀

[wet palm]

connected

then that is ok

yeah man i noticed that also

but i thought "well the pin connected to each other, so the thing is fine now"

[gentle urchin]

Loops are also annoying with this

They return copies aswell

[wet palm]

i love issues

🤣

i feel when i face a lot of issues

i learn fast

since im making a game with many diff settings and logic and stuff etc etc, i face all kind of diff issues

with this ONLY one game i made

[odd ember]

this issue only really comes up with structs in BP

[wet palm]

i learnt alot!

[odd ember]

because structs are always copies

whereas everything else is a pointer

remember to use set (by ref) too

[gentle urchin]

Soo is this a fault of how structs are setup behind the scene?

[wet palm]

there is only set by ref

it worked now, u guys are AMAZING HUMANS BEING

😍

tnx

[spark steppe]

AMAZING HUMAN BEINGS

thanks

[wet palm]

no pronblem!

[odd ember]

probably to do with engine limitations in conversions between BP and CPP

[south merlin]

I have a behavior tree, and when the ai can see the player, and the player is in range, it will use Rotate to face BB entry and then fire on the player. If I run away, and get out of firing range, the TargetLocation for the rotate to face BB entry says it's invalid (only if I mouse over the node. In the keys, TargetLocation has a valid vector). What the heck is rotate expecting? I have a decorator for PlayerIsInRange, and it's set to Notify Observer on Value Change and aborts Both. It's Key Query is set to Is Set and the key is the PlayerIsInRange, but it never aborts as it gets stuck on the rotate.

I'm absolutely stumped.

[odd ember]

in cpp you do take the struct addresses though

which is the same as get or set by ref

[odd ember]

A) if you have a problem, you should always post your code, B) as much as they look alike, BTs aren't BP technically. #gameplay-ai is where you want to post instead

[south merlin]

Roger that, thanks.

I am still heavily stuck on this widget bp

[odd ember]

what is your issue

[trim matrix]

I've told you

[odd ember]

well feel free to repeat it as I can't remember and I don't want to spend time scrolling through a lot of extra pages just to find it

it's your problem, if you want it solved, at least present it in a way where we can help you

[trim matrix]

The bar wont fill up when I press the E key

[odd ember]

okay

try setting this to true

same here

[ebon totem]

no if i print string directly after Event Pressed it does print it so no event is fired

Thats my priv acount btw

[trim matrix]

Nothing

[odd ember]

swap these?

it seems like you're never calling the functions you need to be calling

[trim matrix]

Nothing either

[odd ember]

that should work

I would put a breakpoint on OnInteractBegin and go from there

[trim matrix]

It went straight through and went back to the Array in the Character BP

[odd ember]

did you put it on the red event node?

[trim matrix]

Yeah

[odd ember]

you can step into, instead of stepping over

try stepping into begin progress

[trim matrix]

Went here

[gentle urchin]

It prints 20 of 20 times, but itndoesnt fire 20 of 20 times? Whats the gun shooting logic

[odd ember]

cool, so now put a breakpoint after the branch where you use that node on tick

[spark steppe]

https://tenor.com/view/started-blasting-gun-eyeglasses-so-anyway-i-started-blasting-gif-16955226

[odd ember]

that should work

[ebon totem]

noooo it prints 17/20 times

[trim matrix]

This one?

[odd ember]

after

the next node after

[trim matrix]

And see where it leads?

[odd ember]

see if it triggers

[ebon totem]

its not a BP problem because if it was it should print 20/20 and every player would have the same problem but the problem happends to 2-5% of the players

[trim matrix]

It's triggered

[odd ember]

what's the value added when you hover over the green float pin?

[gentle urchin]

So its an input problem?

[ebon totem]

yes 😦

[trim matrix]

It's 0

[odd ember]

that'll be why then

[gentle urchin]

If so, isnt it out of your control?

[trim matrix]

Is it the progress float?

Because the required hold time is set to 1

[odd ember]

yeah well if the progress float isn't added any value

nothing will happen

[ebon totem]

i hope not because its a game brake for players, i found out that some players of other UE games like DBD and UEturnament have the same problem

[trim matrix]

I set it to 1, I tried it again, it didn't fill up, it just flashed
Which makes sense

[odd ember]

also make sure that it is hooked into your dynamic material parameters. I don't see it anywhere in your graph

[odd ember]

ok that's good news

so we've isolated the problem to be the math

[gentle urchin]

Sounds like the input equipment and drivers should be investigated

[trim matrix]

Dynamic material parameter?

[odd ember]

nope, since it filled up when you set it to 1, that means it's not the dynamic material parameter

it's the progress float value that doesn't update properly

[trim matrix]

Yes but what do you mean by hooking it into the dmp

Oh the dynamic material instance I see

[odd ember]

yeah but since it works you dont have to worry about it

is what I am saying

the math is the issue

[trim matrix]

Oh okay

[odd ember]

I would just do progress = progress + deltatime

and see if that works

[trim matrix]

And what about the required hold time?

[odd ember]

test if it works witihout first

you are trying to isolate a problem

not fixing it yet

[trim matrix]

I see

That actually works but it's incredibly fast

[odd ember]

so you now know the that the required hold time is the issue

[trim matrix]

And the progress values are set to .5 each so I'd just do .2 + .2 or something

[odd ember]

congrats 🥳

[trim matrix]

Nevermind that didn't slow it down at all

[odd ember]

you can still use the hold time

just make sure that it isn't 0

which is probably what happened

[dawn gazelle]

This is also a problem... Progress == 1 is unlikely to happen. Progress >= 1 is.

[odd ember]

we've fixed it already cross that you're right

[dawn gazelle]

Ah ok

[odd ember]

there were a few kinks in the road leading up to this

[trim matrix]

I just dont understand because I followed a tutorial 1 to 1 and it worked for them

But oh well, it works now

Thanks a lot for the help, this is due in a day and you're a life saver

[odd ember]

now go forth and use those debugging skills I've taught you

[trim matrix]

I'll make sure to put them to good use

HeldTime = HeldTime + Delta seconds
Progress = HeldTime/RequiredHoldDuration

Do tutorials just enough to figure out what an actor and component are and then just dive in and do something by yourself. You won't really learn by watching and following.

[trim matrix]

Combining watching and following and then doing something by yourself is the best way to learn

I have been doing just that

Hi, I have a few melee attack animations in my game where the character moves across the screen. Is there a way for me to make the animation only move the player a certain distance depending on where the target is?

[sterile garnet]

i'm having trouble getting "launch character" to work on an AI controlled enemy in my game. anyone had any issues with that or solves?

sorry for my messy blueprints but this is part of the setup i have. basically gets a vector between the player who caused the damage and the enemy, lifts the enemy off the ground slightly to avoid friction, then the vector multiplies by the damage amount, then a multiplier is applied to increase the effect (currently like 5000000 as i was trying to get anything to work)

i was able to get the launch to work straight up, but can't apply it horizontally

[odd ember]

I think it only works without friction perhaps?

[sterile garnet]

the enemy is lifted off the ground before the launch is applied

i have a very similar setup for when the player is damaged that DOES work for some reason, so I think it has something to do with the AI controller overriding the movement

[odd ember]

copy your setup over verbatim to a player class and see if it's supported?

[sterile garnet]

yeah, i did. this is the same setup in my player character (which works)

[heady marlin]

Hello how i can get the "phisyc copy" of the image obtained from steam?

[hybrid ether]

Hello, This is sphere world and I want camera be constant pointing planet.

like this way

[odd ember]

do you still want it to have the rotation of the plane?

[faint pasture]

So what is your question? Or are you just making a statement.

[odd ember]

I think his question is pointing towards the center of the world sphere... which is probably x/y rotations if it works without quats

find look at rotation

z rotation can be either plane or planet

or actually, it might be x/z for planet and y for plane

either way something one can figure out by process of elimination

Hey all, I've got a BP with a "Play Montage" node, however during runtime it can't seem to get past the node (and the animation doesn't play). it doesn't complete, it doesn't report any interrupts, nothing. Any suggestions?

[odd ember]

probably better to ask in #animation. I honestly have no idea how the internal logic of anim montages are

Long ago, I created keyboard key event somewhere in some blueprint. Now I can't find it because searching for one letter gives thousands of results

Nevermind, I can look into stack when it crashes to find another nodes to search for

I'm trying to disable decals from affecting a dynamically created material.

How do I set the decal response parameter via blueprints for a dynamic material instance?

I think it's a scalar parameter enum, but it doesn't show up with the other associations in Get Parameter Info. Plz help

[odd ember]

if it's not showing up, it might not be exposed to BP?

otherwise if you do find it, you can input integer values in lieu of enums, if you cannot use enums

[fierce birch]

@quartz mauve what is it

btw

and how much is to much

Is set ground friction still a thing in ue4?

[trim matrix]

im gonna need some more help

I tried to make a counter since the character collects objects in the game, but the counter doesn't go up when the actor is destroyed

This is the HUD BP

[trim matrix]

Anyone know a way to make the number go up one?

[burnt abyss]

make a variable
get it
drag out from it with a plus node
set the variable as the result

then every time that runs the variable will increase by one

[trim matrix]

What BP would I do that in?

[burnt abyss]

completely depends on what context you're using the number in

[trim matrix]

Collecting items

[burnt abyss]

probably either a gameinstance BP or the player

then every time an item is collected cast to the BP and run the event that adds to the variable

[trim matrix]

How would I do that

[burnt abyss]

do you have a BP for the item

[trim matrix]

Yes

It's this

[burnt abyss]

so right before the destroy actor, add a cast to before the destroy actor that points at the gameinstance

[burnt abyss]

and then put an event in the gameinstance that runs the code here ^

run the event from the item BP and it should work

[unreal wing]

So im having a little trouble with a coin counter UI. Im trying to make it where whenever the player picks up a coin the coin counter UI play a small animation. Ive made the small aniamtion but cannot figure out how to animate it whenever the player picks up a coin. Any ideas?

[mint acorn]

Hey Guys/Gals anyone around who can tell me why my animation montage continues to fire the weapon when it should only fire single/once?? - My rifle animation works fine, I have duplicated this and called it shotgun but this now fires continuosly ????

Hi guys, I want to set allow CPUAccess on Skeletal mesh via BP, but can't find the proper node, there is one for static mesh not for skeletal mesh

[haughty axle]

Wise people of internet.. have a question... Is there any way I can add instanced static meshes in data table? And pull them out in BP and add to array? Now i have few BP's who holds bunch of them for random generation. But thinking to move to "data base" for easy managing and entering. But for few hours couldn't manage to pull it off. I can do that with static meshes and pull them out from data table or strings and etc .. but can't manage hot to do that with instanced static meshes

[gentle urchin]

Whenever coin count changes. Based on this question i'd guess you got a binding for the counter. Otherwise you could simply use the existing function/event that is called whenever player picks something up.

If you really really wanna use the binding, you must cache the current coin count in the widget. Then whenever cached value != incoming value -> do the animation then set cached value == incoming value

[unreal wing]

yah im using a binding, ill send a screen shot

so im not sure what to do from here

[gray chasm]

This seems like something obvious which I'm missing; if I have an actor with say, 4 boxes on it, and I want to have a different behaviour depending on which box the player is in, how do you do that? the overlap event only seems to specify the two actors, and the on-hit event doesn't let you determine if you're currently overlapping or not.

ah, nevermind. Get Overlapping Components

[amber dragon]

Good morning, does anyone know how to fix this bug?: "failed to load (asset) can't find any" That message is appearing every time that I try to package my game, which causes to me not being able to it

[dawn gazelle]

What is it about the instanced static mesh you want to store? The mesh it uses? The instances that you're making?

[haughty axle]

@dawn gazelle the mesh it uses, but i think i will go without data base for these things

[trim matrix]

Idk what the "Gameinstance" is

I understand now

[trim matrix]

??

[timber knoll]

Why would you do that in game instance?

If your character collects the other actor = character

In which case you can just have it store the counter and HUD attached as well to update the display every time you pick up something

[trim matrix]

Im gonna need you to dumb it down for me, I dont understand shit man

[timber knoll]

Do you have the counter in your player character/pawn?

[trim matrix]

I have this in it

[timber knoll]

Make sure it has one, and create an event or function

Ok good

Then once you collect item

You check if the other actor is the player by casting

Which you do alright

So just add the event before destroying it

[trim matrix]

So call this logic before destroying it?

[timber knoll]

Yes from player object > collected teru > destroy self

Inside your teru beginoverlap

So your player will know it has collected the teru

[timber knoll]

And can handle the logic from there

The blue pin on the right side of the cast

Should be connected to the collect event

[trim matrix]

Ah I see

Oh my god you're a life saver, thankyou so much

[timber knoll]

So now that should increase your counter

[trim matrix]

I can add variables or functions to particles and use those to change the particles right?

[timber knoll]

Yes just like with materials

You can change the parameters

[trim matrix]

I want the rain I created to get less heavier with each teru collected

and on the final one it'll be normal weather

[timber knoll]

Then you would have to decrease the spawn rate

I’m not 100% sure how to do it but shouldn’t be too difficult

[twilit heath]

you'd probably want a parameter on material parameter collection for that

as you'd need more then 1 material to drive the weather

we have over 20

[timber knoll]

He’s talking only rain particles 😛

[twilit heath]

and it would be a pain in the arse to set a parameter on each of those individually

things tend to grow

[trim matrix]

I cant figure out how to add variables to the particles

[timber knoll]

In niagara you can add parameters

And then you should be able to just change the value in blueprint

[trim matrix]

I'll give this a shot

[spark steppe]

and afaik you can use the same parameter for different subsystems

[gentle urchin]

Save the coin amount in the widget for comparison . If coin amount from player is higher than the saved value, play the animation, then save the new coin amount

[trim matrix]

I got this setup in the particle blueprint
I want it so when a Teru is collected/destroyed, the values on the particles will decrease

[spark steppe]

is that a question?
