blueprint

[lofty rapids]

you could do a parent of all things you want to make invisible, and the child of that, is the parent of NPC, etc...

as a hierarchy

then like you say it will be one cast, but one or two i don't see a difference, but maybe you get a lot different stuff it could get quite messy chaining these things

[ivory vapor]

Ok, so here's my version for now. For some reason it have issues, I haven't seen an NPC get out while the black box was visible yet. But when NPC get in, sometimes the black box get invisible for a short instant as if the player got in.

[ivory vapor]

Can I add parents to an existing hierarchy in between two BP?

[lofty rapids]

you can create a parent and re parent i think, i've never done that but i think you can

[lofty rapids]

ya this is wild, i would just use a box collision overlap

[void crescent]

That delay might cause issues if he turns in the 0.5 secs he would still do the setvisible

[lofty rapids]

and your not using the other actor

[ivory vapor]

I have a collision box, without it the overlap events doesn't work

[ivory vapor]

The NPC?

isn't how you cast to it?

[lofty rapids]

goto your box that you want to collide

click on the box collision in the components top left

in the details

at the bottom are the events you want

on component overlap

so that when things overlap the box collision

[ivory vapor]

Confirmation: The NPC get in and out but when they do the black box disapears, it reappears when no NPC is getting in and out as if ti was doing both branches everytime

[ivory vapor]

got them

[void crescent]

You are doing the set invis and set visible logic from the box BP? Or do you do some Capsule OnOverlap from character?

[ivory vapor]

I plug other actor directly into cast to bp player then?

[lofty rapids]

get rid of get player pawn

[lofty rapids]

yes, other actor is the thing that is overlap

so your casting or checking to see if it's the player

then if that fails, check if other actor is the npc

[ivory vapor]

So this?

[ivory vapor]

yes from the box bp

[lofty rapids]

get rid of get owner

you want other actor

[ivory vapor]

ok

[lofty rapids]

and you want to out of the cast failed at the bottom, check if its an npc so you can set it's visibility back

you check for the player and set the visibility on success

but on fail you don't have the check for npcs so they will just be invisible and never go back

[ivory vapor]

And I need to cast npc in begin overlap to set npc getting in the black box invisible too I think

[lofty rapids]

show what you have now

you can add the if the box is visible check after

for now just make them go invisible, and back

thats what your goal is here, you can add a boolean for if the box is visible after

[lofty rapids]

are they changing visibility going in and out now ?

[void crescent]

There's still a Delay.

[ivory vapor]

Oh yeah good catch

I forgot it

but it works, they are not setting the black box visibility anymore as well.

I think next thing I can try is move what's in tick into a custom event something like "setoverlappedactorvisibility" and call it after the set visibility of the cube in the cast to bp player.

[lofty rapids]

you don't need the tick anymore, your still running that ?

you don't need any of the old code for this @ivory vapor

this should work with just whats in the picture

a good benefit of doing it this way is these things only trigger when the character start and end overlap

instead of what you had which was constantly checking

big performance difference

[ivory vapor]

the tick is what makes the npc react on box visibility, without it they just react on begin and end overlap. Which is why I want to put its code in a custom event that I call after the box visibility is changed.

[lofty rapids]

oh ok, can show that code ?

because i think you can offload this thing to the component overlap

theres really no need for loops on tick here, especially plugged into pure nodes

[ivory vapor]

Imagine this but in custom event called after a change of the box visibility

[snow halo]

Hi, I have some questions.

Im really not that good at design or widget design etc.

This is a chest container im trying to create next to my own widget.

The problem is I don't fully understand how this inventory grid works.

It seems that everything is inside of another thing

[lofty rapids]

ya so you see where you have a branch and your checking isvisible ? the stuff comming out of the true can be added to top of the component overlap start when you cast to player successfully and set the visibility

same with the bottom one comming out of false, set it on the component overlap end, on successfull cast of player when you set it's visibility

instead of this tick stuff

tick isn't bad, it's just in thhis case it's better not to use it

[snow halo]

This is the widget im trying to fix, its player menu, it seems like everything comes from here and its filling up on begin play with slots etc. I need to make another instance of this into my chest container 🧰 but I still dont understand how this thing is beign created

[ivory vapor]

So I need two custom events, one for true, and one for false? Or I can call the same for both and let the branch do the work?

[ivory vapor]

Do you know who made it?

[lofty rapids]

do it in the component overlap instead, when you set the visibility think about it, it's now set so you can run the code, instead of checking constantly and applying the code, instead of check tthe visibility, on the component overlap event you already know the state

because your setting it

[snow halo]

yes, a guy on youtube named lisowi, but at this point Ive changed it a lot to fit my own needs

[ivory vapor]

So like this?

[lofty rapids]

yes exactly

and add the other code to the component overlap end

[ivory vapor]

Maybe he can still help you? I don't know much of widgets, only ones I created are from tutorials I followed, but I would guess it's harder to understand without actually manipulating it than blueprint

[lofty rapids]

and it "should" do the same thing lol

[ivory vapor]

I'll test it

[lofty rapids]

thisi s the main widget that holds everything ?

search for create widget

[snow halo]

its not rly about widgets, this is all bp oriented

for example on my character I have this component

and here you control the slots that are going to be created on begin play

[lofty rapids]

^

this is how a widget is normally created

and then add to viewport

[snow halo]

here's the create

I dont see an add to viewport node though

[lofty rapids]

this is a sub of the main if they are all inside

there should be anothter place

create widget

[snow halo]

these are the 3 main ones, I just showed you W_InventoryGrid

[lofty rapids]

here is creating the items from the inventory, not the creation of the main wiwdget

[ivory vapor]

It does, I set one to be static and a few others to roam around, they get out and in of the house on their own. Everything in the black box isn't visible if I try to see through and if I get in the black box I see them and if I go out the black box come back and hide them again :D

Thanks for all the help I wouldn't have achieve it without you

[snow halo]

yeah it seems like its nested inside of this canvas here

[lofty rapids]

ya this is created at some point, the search you can keep going and find the next one

theres probably more create widget

[snow halo]

This is probably the one expanding etc.

[lofty rapids]

widget have to be created at some point

in order to use them

at some point you create widget W_Player_Menu

i think this is your main outer widget

[lofty rapids]

you'll see a node like this create widget, but the class will be set to a different widget

[snow halo]

so duplicated ??

[lofty rapids]

idk what you mean by that ?

[snow halo]

btw how is it possible that this widget is not added to viewport after being created

and yet its on my viewport?

[lofty rapids]

because it's already in the viewport nested into one that is added to viewport

search for add to viewport

[lofty rapids]

glad to help, tick is ok so you can use that technique for something like this.
but just as an fyi big loops in bp are bad, in general you don't want to loop over a lot of things a lot of times

so for a couple npc np maybe no problem, but a lot of items and your looking at a big issue

[snow halo]

I just wonder how am I going to create new database this time to remember and save the items that I store it etc. This is going to create a lot of complexity I feel like

[ivory vapor]

I usually avoid tick for everything that doesn't need it, but it adding more complexity with conditional custom event calling for testing didn't sound good until the thing worked

[lofty rapids]

right so in the case you want to do that, a more efficient approach would be to check for a change in the boolean, instead of running both branches one or the other all the time, check for a change in the boolean, if it changes, then run it and run it once, then the old boolean is set to the boolean value, and you can check for another change

this doesn't run every tick, it would just do the loops if the boolean changes

[ivory vapor]

I mean I just kept it in tick while testing, I always intented to move it to custom functions and since it just works in the overlap events it's even better

[lofty rapids]

your original question was where the thing is created, the main widget is usually created with create widget, then added to viewport, this will load all the components in it so if a widget is in a widget it will load it

[agile moss]

why??

[lofty rapids]

this is what i'm talking about

[snow halo]

I think I found the right place where it's being created

or no, this is actually a widget im not using at all

[lofty rapids]

that looks like something seperate

[lofty rapids]

play round remaining anim target is an actor, and you have a specific type of actor as a reference

the types don't match and there is no valid conversion

[agile moss]

sooo, how do I do this

[lofty rapids]

you trying to run a function ?

[agile moss]

an event

[lofty rapids]

ok so is the event inside the widget actor ?

the widget manager

is the event in there ?

[lofty rapids]

ok so try to just when you drag out from the ref, type the event name

itt should show up in the menu

it looks like you copied the node from somewhere ?

it's usually best to get it from dragging out

[snow halo]

question, how am I going to implement a character component to my chest widget? (unless if I implement it into the chest_bp actor)

unless if I implement it into the chest_bp actor
although thats probably a good idea

[agile moss]

u mean this?

it just instantly disconects it :/

[lofty rapids]

search for "play round"

thats what your events called

also check context sensitive for now it should be fine

[agile moss]

I hate this engine, with a ref it doesn't wanna work for some reason

[lofty rapids]

did you right click and do promote to variable ?

[agile moss]

yes

lemme redoit

well would you look at that

thanks dud

[burnt citrus]

I have a general question about timers (when you create them looping set timer by event for example): when you end a level and load another level, do you still need to kill them or the engine do it in automatic?

[lofty rapids]

"All timers tied to destroyed actors are automatically invalidated"

this is what the web says about it

[burnt citrus]

ok good, thanks

[wheat knot]

Hey Unreal devs! 👋

I've been working on a plugin called BP2AI Parser that converts Blueprint visual logic into structured text that AI tools can actually understand and analyze.

The Problem: While C++ devs can copy-paste code into AI tools for instant bug analysis, we Blueprint developers are stuck with screenshots and inefficient image analysis that can't match the precision of direct text input.

My Solution: BP2AI Parser generates two outputs from any Blueprint:

**Structured markdown **→ Copy-paste directly into any AI for debugging/analysis

Interactive Flow Inspector → Human readable with Syntax Highlighting, Navigate complex nested functions, collapse& copy sections

Questions for you:

Does this solve a real pain point for you?
What Blueprint debugging challenges frustrate you most?
Any specific features you'd want to see?
What would you pay for a plugin like this?

What do you think?

Curious to try it when ready? I'm looking for beta testers with interesting Blueprint challenges - You can sign up if you want updates: https://docs.google.com/forms/d/e/1FAIpQLSfn1lyFt86mBNPvOvtJD9Bz9zZlzA3383JmAejDD3H8IMIjHA/viewform?usp=header

[dark drum]

For does this solve a pain point, that would be a no from me.

Showing a c++ equivalent would probably be more helpful.

[dawn gazelle]

This is just an honest answer - I am all for AI revolutionizing how we do things, but at current technology levels there's still a lot to be desired. I do salute your efforts at trying to further AI development like this.

Does this solve a real pain point for you?

No. Once you're properly proficient at reading through code (both C++ and Blueprint), you normally can spot bugs and problems on your own, and have an idea of where such bugs may be popping up and why. I still consider myself an intermediate user of Unreal despite having about 6 years of working with it. Even if I'm looking over someone else's code, I'm fairly quick to spot issues even if they're using systems I'm not familiar with.

What Blueprint debugging challenges frustrate you most?

Things that wouldn't be solved by issues in code - namely the tools available to inspect values at run time.

Any specific features you'd want to see?

Automated conversion of blueprint code to C++, but I think your tool may only be able to do pieces of the code at a time unless you're somehow able to read an entire blueprint and know how to appropriately call out to other objects.

What would you pay for a plugin like this?

At the current state of AI, I wouldn't pay anything for this type of plugin due to unreliability of the underlying technologies. AI is getting pretty good, but it's still not quite there.

My main concern with a plugin like this is that you'd effectively be targeting people who don't know how to step through their code, which is already a big problem we face quite frequently in this Discord. The current state of AI with C++ requires you to know how to read the C++ to know that it's actually good code and that it is usable in the way you want, and that it will actually appropriately compile. A blueprint version doing something similar would mean the person using this tool would need to ensure that your parser has appropriately read their code (learning your markdown) and spot where the AI may have faltered in whatever response back.

[lofty rapids]

"What would you pay for a plugin like this?", i don't need it personally but it might be helpful for others

how would you train the ai to understand it ?

[wheat knot]

Interesting, thank you all for your feedback!
To clarify how this works: The tool translates node executions to text, tracing through all selected nodes including custom events, collapsed graphs, functions, macros, and interfaces within your Blueprint boundary. It recursively resolves pin inputs, capturing complex math operations, nested calculations, flow control logic (branches, loops, switches), data structures (arrays, maps, structs), and multi-level function hierarchies. This ensures the generated text maintains the exact logical flow and relationships of your visual Blueprint for accurate AI analysis.

For analyzing the complete Blueprint, just press CTRL+A in the Event Graph to select everything, and it translates into token-efficient text. With multiple event graphs, you select each manually.
Any text-based AI can read this markdown output natively since it's structured text. Complex logic flows like branches, sequences, switches, and arrays are all formatted to be understood by AI text analysis capabilities. With this text-based output you can then ask AI to fulfill your individual needs like:

• Find bugs and edge cases, especially in complex math formulas | you interpret and validate findings, not magic detection
• Generate technical documentation for team knowledge sharing | you guide the format and content
• Assist with Blueprint-to-C++ conversion | you orchestrate what gets converted, not magic automation

This isn't targeting developers who can't debug - it's for developers who want AI efficiency. Just like senior C++ devs paste complex code into AI tools for second opinions or documentation help, this Plugin would give Blueprint devs that same capability.

This is a translator, not a magic code generator. The quality of bug detection, documentation, and C++ conversion heavily depends on your prompting skills and the context you provide alongside this text.

[frosty olive]

Does anyone know how the set wheel friction multiplier works in ue5? I have a chaos vehicle and I'm trying to change the wheel friction in blueprint so I can change it while playing but I can't figure out how it works. I have it set at 99 to see if anything happens but nothing changes. I think that's the only thing it let's me select as target but not sure

[lofty rapids]

whats the base friction ? web says that can effect this since it's just a multiplier

just for test purposes i would use a single variable

so you can just set it once and it sets all four

and adjust the variable up and down real easy to test

[frosty olive]

Its 3 at rear and 3.2 at front in their blueprints

[frosty olive]

You mean this? I set it at 20 and it's still the same

Actually when I set it at 0 the wheels just spin and it doesn't go anywhere

[lofty rapids]

ya this is just easier to test

but #chaos-physics might know more about what these values should be at for whatever you aree wanting

[frosty olive]

It seems to be working but it's a bit weird

[frosty olive]

OK, I'll ask there later if I can't figure it out

Thanks

[static forum]

what are some high level blueprint concepts that you use all the time after you took the time to learn them?

[sick sky]

Main issue with UE and AI is that AIs don't understand UE well.
So it doesn't really matter how detailed your prompt is.

[dark drum]

Hierarchy, function only base classes and composition.

[static forum]

so creating children and referencing the base classes function?

[dark drum]

Yes.

[static forum]

Thank you, I have already started this mostly

[dense badger]

Heya all, I have an esoteric BP issue that I'm not sure has a solution. But curious if anyone has run into this:
1: I have a BP with a custom component on it
2: The component has some params on it with user supplied per instance data
3: During the BP's construction script the actorBP is iterating it's components and calling update
4: When that update is called all the instance data is ignored and instead the base class data is used

Is there any way I can get it to use the instance data?

[static forum]

I am trying to figure out if there is an easier way to make my inventory. I have bpi and a working inventory all that good jazz. I want a equipment slots that update my players stats, but with my current setup following this tutorial he has only inventory. What I was going to do was have a per player instance entity that is a container that holds the players inventory XD

[static forum]

I am just double checking... sorry if its dumb, are the varibles instance editable and expose on spawn?

[dark drum]

I've not found any way myself.

[dense badger]

I have not set expose on spawn, but they are instance editable.

[static forum]

well to my knowledge expose on spawn lets it take in info, I think?

and are you dragging off the component and saying set?

like this

cause otherwise you are just setting that varible in the actor

sorry if I am giving dumb answers, might as well double check the easy stuff

[dense badger]

I'm inside the component when this is happening. I'm just doing a get on the properties. But this is on Construct in the editor.

[dark drum]

The construction script does some funky stuff with the BP state. It runs before the instanced data is applied to its components which is why it uses the class default data.

[dense badger]

In game, it reads the correct instance data

[dense badger]

Yeah I assumed this was the problem.

[static forum]

how would you add a filter to a slot to make it so I can not drop a helmet onto a chest piece equipment slot?

[last peak]

With a enum

[wet swan]

Reply is a bit late but yes, im attaching actors to a pawn, and when that pawn moves all its child actors does not have collision since only the parents gets swept

[faint pasture]

they have collision, just the movement component doesn't care

you'll have to handle that on your own

[celest oar]

im trying to implement a custom anim notify so that my particle effects only play when the mesh is visible, does any one know how to do this? i extended a class in BP but it only has 2 methods that you can override and one of them is for the name and the other doesnt seem to do anything

[surreal peak]

What class did you extend and what methods do you see?

[celest oar]

well, right now i am trying to extend "UAnimNotify_PlayNiagaraEffect" in c++ cause google AI told me it has to be done in c++

i am also still on 4.26

google is telling me i need to override this

[surreal peak]

Hm okay. Where do we start...

You don't need to extend inside C++, you can potentially extend from the Niagara one in Blueprints, or just extend from the base class and create your own.
And for the "only if the mesh is visible", you don't need to do either of that, in theory. You'd just set your SkeletalMeshComponent to only Tick Pose if Rendered.

Since the Pose will drive the Animation, if it doesn't tick the pose when not rendered it won't play the animation and won't trigger the AnimNotifies.

[celest oar]

i need the animations to always play cause i want the camera to move with movement

[surreal peak]

Well okay, not gonna question that. Try to extend in Blueprints then.

UAnimNotify is Blueprintable

Should be the same for the Niagara one

[celest oar]

i did without sucess, let me show you what options .26 gives you, you might be able to do it in later versions but i think .26 is limited, i might be wrong tho

[surreal peak]

Yeah that's correct though

[celest oar]

so how do i go about doing that in BP?

[surreal peak]

What are you missing?

[celest oar]

i was assuming that the return on the receive notify function would make it play or not

but that doesnt seem to be the case

[surreal peak]

What's the parent of that BP?

[celest oar]

if it returned true it would play and if it returned false it wouldnt

should be animNotify

[surreal peak]

Right, the boolean isn't use in C++ at all iirc.

[livid dune]

Hello, I had a question, has anyone done any time dilation with blueprints before?
For example, if I wanted the user to press a button and slow time.

[celest oar]

so am i right in assuming i need to use c++?

[surreal peak]

No, the boolean doesn't really matter here.

If this is a normal AnimNotify, so not the Niagara one, then you need to spawn your Niagara effect if your branch is true.

[celest oar]

i do that in my gameMode class in c++ should be easy to expose to bp if its not already there

[surreal peak]

Overriding the Niagara one won't help, as that will only call the notify after the Effect is already spawned.

It's coded in a way that it allows you to use the notify function to set niagara user variables

But if you want to fully prevent the spawning you just use the base UAnimNotify

And call the code to spawn an effect by hand.

[celest oar]

ok i will try that

[surreal peak]

The answer to that question is probably "Yes someone has done that."

You'd want to maybe rephrase that to an actual problem you need help with :D

Time Dilation + Blueprint is otherwise something you might as well have entered into a search engine.

[surreal peak]

btw, AI for coding is shit if you don't know if what it tells you is good or not.
You are doing more harm to yourself than anything else.
I would suggest to drop the habit of asking it about this stuff.

[celest oar]

oh, i didnt ask it just gave me the answer automaticly on google and since i didnt have anything better to go with i decided to give it a try

[surreal peak]

That google AI is nothing else than another ChatGPT

[lofty rapids]

ai is a lot of the times incorrect

and especially for blueprint it says shit that doesn't exist

[celest oar]

i think my logic is correct but the effect doesnt play in game for some reason

plays fine in the animation editor tho

[surreal peak]

Could be that the IsVisible returns false for editor?

Oh it does play in the editro

AttachmentComponent is missing btw

On the top node

[celest oar]

ok now it works

but it still plays 2 animations

all this and the problem is still there

[surreal peak]

IsVisible is not what you want.

You probably want Recently Rendered

[celest oar]

will try

ye that was it

but why doesnt "IsVisible" work?

[lofty rapids]

what is supposed to happen is is visible is false ?

[surreal peak]

Because IsVisible is just returning the boolean that controls if you want the thing to be visible overall.

[celest oar]

nothing

[surreal peak]

The one you can click in the defaults

[celest oar]

ummm, so i should be using ownerSee or somethingl ike that then

well, recently rendered should work better

Thanks again eXi, you have helped me a few times now, i apreciate it a lot.

[surreal peak]

If you just want to hide it for the Owner, then OwnerNoSee would do the trick for the MeshComponent. For the NiagaraEffect this could also work, but not sure if that automatically works via attachment or if each Component needs that individually.

[celest oar]

its networked so i feel like it would be a bit messy to use those vars, im gonna stick with the rendering node

also, i wish listed ever shire, if it ever goes to like 50% discount i will buy it, you have helped me quite a few times.

thinking better, i just bought it, its only fair.

[surreal peak]

Ah, appreciated. (: But please don't spend money on me if I help you in my spare time.

its networked so i feel like it would be a bit messy to use those vars
Those variables are meant for Networking after all. They are usually used to show/hide FirstPerson vs ThirdPerson meshes.

[rapid smelt]

How do you set up a blend time between animation transitions in the animbp? like a blend time between crouch and regular stance for example

[dreamy kindle]

https://gyazo.com/2801a325b469b7fcaea9f11b51e70e93 hi any idea why the crouch and camera seem off? I have them parented to a camviewer bone parented to head ? it looks like its working in 3p replicated not sure why it hides

i got fixed thanks

Anyone know why the anim jerks the viewmodel away arms like this? Perhaps a blend setting in state machine or transition rule? https://gyazo.com/38c6f924e7a9a4e00ae5f48c9dfa1b77

[hazy fulcrum]

Hello all, there doesn't seem to be a lot of people asking this, but is there a way to set a minimum movement speed? Ideally I'd like to have a character that can either walk or run with no movement speeds between those two states. 🤔

[summer sail]

You can just change the speed of the character movement component during gameplay.

[summer sail]

I have run button on my game and it does something like what you are trying to do, when I press run, it just updates the speed value, when I let go, it rolls back to walking speed.

Ignore that blue box in the middle it does some other stuff that doesnt matter for this example

[hazy fulcrum]

Of course, but what I'm trying to do is prevent a slight thumbstick input from giving me a speed other than the specific walk/run speeds.

[summer sail]

Oh! Use clamp!

You can clamp or you can do a select

@hazy fulcrumSomething like this maybe?

not sure if my logic is correct but:
if the stick is at 0, spits 0,
if its over zero or below 0.5 it walks
if over 0.5 runs

[cunning cloak]

I feel like I'm not understanding something fundamental about rotation. I have here a PaperZD project I'm working on (yes, still using the online course's assets, lol), and wanting to add a "walk on walls" mechanic. I have set up collision boxes to only trigger this effect when you are near it; Red for the right wall detector, green for left. However, you'll see in the video that once I go 180 degrees around (on the ceiling), my actor flips around, and now red is on the right, and green is on the left. Can anyone see what I've done wrong? Again, I feel like it's an issue with my understanding of how rotation works...

Note: My variable "Level Rotation Direction" is either -1 or 1, depending on the wall that has been detected.

[hazy fulcrum]

So just to update for the lovely people here who have replied to me, I did end up finding this post: https://dev.epicgames.com/community/learning/tutorials/lwlG/unreal-engine-your-first-60-minutes-with-motion-matching

If anybody is looking to implement something similar to what I want, the 'Clamp Input Scale' function they set up as part of that tutorial is basically exactly what I needed.

Thank you for the suggestions though, @summer sail! 🙂

[dreamy kindle]

https://gyazo.com/f2d8b02fc59424ddb9c5854a66964909 ok fixed it needed lots of improved poses and rebakes

[cunning cloak]

To add on to my previous question: I've found that rotating my actor (specifically the sprite, but I think the logic follows) 180 degrees on the Y axis, will actually change the X and Z axis instead. I think this is what is happening when I rotate my actor. Is there a way to force it to just stick to the Y axis, rather than assume I want to flip the X and Z axis?

[surreal peak]

That's Gimbal Lock. Only way around that would be using Quaternions.

[cunning cloak]

Ugh, I've been reading about Gimbal Lock and Quaternions. I'm scared of the can of worms that opens, lol. Might just come up with a different solution.

Thank you, though!

[narrow sentinel]

So i have an odd issue where for some reason when a box collision goes into a sphere collision I don't seem to get any overlap occuring from the sphere collision at all

I've break point on it as well but just doesn't seem overlap it being fired

okay so its working now but thats cause I've configured the collision settings on the ship box collision to overlap when it hits a world dynamic object thing

[ivory vapor]

Hello!

It's me, about my hide actor in room box again. I've noticed an issue and I'm trying to find its reason and fix but I'm struggling. I paste the whole blueprint again in this message so new people can read it. It's basically a box with a black cube in it that hides every actor inside as long as its visible and become invisible when the player character overlap with it.

I thought it would work out of the box for floors by making one of each of those box on each floors as the box from the floor the player is currently in would be invisible but the upper one's would be visible and thus hide any NPC that are in the upper floor or any npc leaving the player's floor for the upper floor. Thing is, it works to hide the upper floor character when you are in the bottom floor, but when actors move in the bottom of the stairs that are well in the bottom floor they disappear and often never reappear unless they leave the box/player leave and reenter the box. Here is a video showcasing the issue (I've set the black boxes to translucent so you can see what is happening. I don't really know what could be making this issue in that area as it's not the spot where the boxes are close and actors could technically overlap both at the same time (also the boxes don't touch.)

[lofty rapids]

so your boxes overlap ?

[ivory vapor]

They don't, theres a gap between the two

[void crescent]

I don't think that's the problem.

[lofty rapids]

i was thinking when they leave the top, enter the bottom they are going invisible

[void crescent]

If a new character enters the box while your player is already in the box it just does the invis part. So you would not see it even if you are inside right?

[lofty rapids]

i think you want to check the box visibility before you change the npc

[ivory vapor]

Well you see the visibility change in the video

the disappearing isn't made in material

but in blueprint

[lofty rapids]

what i'm thinking is the logic says make invisible when overlap

[ivory vapor]

with player yes

[lofty rapids]

so when they leave the top, they hit the bottom and go invisible

because this is what the logic says

i believe you want to check if the box is visible before making them invisible

[ivory vapor]

oh

[lofty rapids]

i think like neut mentioned, they are just going visible on overlap

[ivory vapor]

Like this?

[lofty rapids]

right

thats what i'm thinking

[ivory vapor]

With this addition they are visible even through the black box from the outside and when inside they are visible on every floor no matter the one that is set visible or not... Maybe it's time to set debug strings?

[narrow sentinel]

Anyone know if I can in my level sequence take the transform of the actor i've assigned rather then the sequencer using a set transform for the initial key frames

so idea is this start bit of the sequence I want the actor assigned to move to the key frames set, in a sense kind like it moving into place for the landing sequence but I want it to be in a way where it doesn't need to have gone to a specific location etc it can be anywhere in the world and it moves in that intial bit

so it's blending I need but not sure where to turn it on

[void crescent]

Is this multiplayer or singleplayer?

[ivory vapor]

Single those are NPCs

I've tried adding two simple debug screens and waited for NPC to move between floors and only this one printed every single time no matter which way they were going

[void crescent]

Then I would suggest you just register the player if it enteres the box and unregister it if it leaves the box. Instead of the is box visible thing make some is OverlappingPlayer->IsValid? True-> make visible -> false- make invisible

[void crescent]

OnOverlap If cast to player is true set a player variable. If cast to NPC is true check if the player variable is set. If yes make it visible otherwise invisible.
OnOverlapEnd if cast to player is true reset the player variable.

[ivory vapor]

Something like this?

[void crescent]

This would do as well

[void crescent]

but I would set the variable sooner. Not after the cast to NPC.

[ivory vapor]

just added the same logic but with set to false for overlappingwithplayer in cast to player for onoverlapend and tested.
I still get the same issues: The actor disappearing at the bottom of the stairs (I checked the whole stair is in the black block) and since I added the new branch after the cast to npc all actors are visible no matter which floor their in and when they move from floors the game only print "overlap invisible"

I can try that

[void crescent]

Also you have to make sure to reset the variable if the player leaves the box.

[ivory vapor]

I moved it between the set visibility of the box and the start of the loop

[void crescent]

OnOverlapEnd make bool false.

[ivory vapor]

Yes I did

unless I'm missing something

I'm still getting those issue for some reason

Oh it said overlap visible this time

[void crescent]

You have to switch the invis with visible and vice versa.

this is wrong

[ivory vapor]

I swapped the true and false to see if I had my logic wrong and it just moved the spot where they disapear (red square)

[void crescent]

Shouldn't they get invisible if they leave the box?

[ivory vapor]

If they leave the box it depends on the overlapwithplayer branch

in overlapend

[void crescent]

This must be flipped as well.

[ivory vapor]

The true and false? I just flipped it

[robust belfry]

hello i have one question , do you know how to put cooldown after jump but my problem here is when i click 2 times spacebar after cooldown it's rejump ??

[void crescent]

At end overlap if the NPC leaves the box and the player is overlapping with the box then you would make the npc invisible. I'm not sure what you would do if the player is not inside of the box and a NPC leaves. Would you make them invisible as well or would you make all NPCs visible that are outside any box?

[ivory vapor]

I think I fixed it by changing those, I'm still testing, but the actor is not visible through the black block anymore, they don't disappear in the bottom stairs anymore and they seem to disapear when going to the upper floor

those box were previously set exactly the same, now they are inverted based on if it's end or begin overlap

[heavy thorn]

wtf

[robust belfry]

sry i hv bad english

[heavy thorn]

I mean it's super simple

[robust belfry]

oh im starting programmation so

[heavy thorn]

You just need to record the time when jump is pressed

Then before jumping, determine whether the current time exceeds a certain value

[robust belfry]

how i record lol ?

[heavy thorn]

Your super BP newbie?

[robust belfry]

yea

[heavy thorn]

This is not good

[robust belfry]

where i put the get time seconds with delay ?

[heavy thorn]

Delay has many problems and don't cause trouble to others

[heavy thorn]

omg

[robust belfry]

im so dumb sry

[heavy thorn]

wait I'll write a short blueprint for you

[robust belfry]

thxxxxxxx

[heavy thorn]

[lofty rapids]

theres a few ways you could also user a timer by event

[ivory vapor]

It works almost perfectly, the only issue is that the disappearing points of both cases (npc going down from upper floor and npc going up from bottom floor) are not close or in the same place and the bottom one is at a pretty weird spot, I think it's level design related with the placement and size of the box but the weird thing is that in my level the bottom floor black box goes way upper than that point. I'll try making it go right below the ground of the upper floor but I'm not sure if it can cause issue if the box overlap so I'll try to avoid that

[heavy thorn]

That is it

Copy it all and paste it inside the blueprint

[robust belfry]

how do i paste your code

[heavy thorn]

The entire content of this txt file is the blueprint node

Just copy it

[robust belfry]

oh yea thx

[lofty rapids]

without a delay, but same concept

[robust belfry]

do i have to create a var float

? @heavy thorn

[void crescent]

Yes... if you wanna go with time then you need that float.

[heavy thorn]

Yes you must use a variable to describe and record some state

[ivory vapor]

Yes the bottom box seem to disappear ealier on the stairs, I think it's because as soon as even a pixel of their head touches the upper box they disappear, I don't know if I can do anything about that. That's the best I could get so far, making the bottom box any bigger make it keep npcs in the upper stair visible from the bottom one.

[heavy thorn]

Whether boolean or floating point

[robust belfry]

like that

?

[heavy thorn]

You always need a variable to determine whether it is cooling

[heavy thorn]

yes

[void crescent]

Yes

[ivory vapor]

Thanks for the help btw Neut!

[heavy thorn]

If ia jump does not trigger, use your own ia jump

[robust belfry]

but first time i have to wait like 5 seconds to jump

[heavy thorn]

Oh, there seems to be a bug

[robust belfry]

i have modify the 5 by 1

[void crescent]

If you deal with the time you have to set it... and you have to make sure you really use the subtract as posted. If you don't use substract you might get an issue if your game runs for many days because the positive swaps into negative and you would compare some - with a previous set + value. I guess UE is bending the value as well like C++ (I hope). In my opinion this is some simple task that can be done with either. Timer, delay or that timer value.

[heavy thorn]

emmmmmm I don't know how to solve it but I think I should change the floating point value to 999 or -999 or something like that

🤔

[robust belfry]

look the video you will understand bug and why i want a cooldown

[lofty rapids]

this is an option, i use timers personally quite a bit

[heavy thorn]

Use their solution, they are more experienced.

[robust belfry]

but how i use your solution beacause i have enchanced trigger

@lofty rapids

[lofty rapids]

i just used a custom event, you just go out of started instead

[void crescent]

If you would use the time-float solution then set the time variable once in your begin play or construction script so it is not 0.

[robust belfry]

ok im making the script

[heavy thorn]

I never realized this was a bug.

🤣

[void crescent]

I think it might be fine all the time if UE is just mapping it. This was in issue back in days where you had to expect negative values.

[robust belfry]

@lofty rapids what's in the event ?

[void crescent]

Anyway if I look at your example I'm not sure if you really would use a delay ... or if it is a better idea to respond to some notify. 🤔

[robust belfry]

setcanjumptrue

[lofty rapids]

so the timer fires off, and runs that event after the time expires, i just named it that

and inside that event you can see in the picture i set the variable back to true

[robust belfry]

but what's inside the event

[lofty rapids]

wdym "whats inside" ?

the custome event is right there

inside the event is the changing of the variable to true

[robust belfry]

oh im sry i didn't understand

[lofty rapids]

you add custom event

then hook it up to the timer

and when that timer goes off

that event fires

[robust belfry]

@lofty rapids

[void crescent]

I think you have to fix it in your anim-bp. You should not play the landing anim if you are moving or jumping again already but take a transition to jump start or something. Also your air-control seems a bit too optimistic.

[robust belfry]

i can't jump anymore now lol

[lofty rapids]

set the boolean to true as default

[robust belfry]

ok

thxxx

[lofty rapids]

i believe a timer is frame independent was well

so thats a plus

[robust belfry]

thx you too for tips i will do all your tips thing

[void crescent]

I never had an issue with delay so far btw. You just have to know what it does and what it doesn't. But using that timer event should do as well.

Also the timing float is fine. Did so back in 2000 a lot like this. 😄

[lofty rapids]

i think things like "delays are bad" is similar to "casting is bad"

[void crescent]

But I think a neither should be necessary. If I hit jump 10 times while in air already ... nothing happens. I don't have to take care of this. But you have to respond in your anim BP different if you are moving or if you are just idle as you might not want your landing anim played that long in each case.

[lofty rapids]

it's really in how you use them

but theres a few advantages to using timer over delay

[void crescent]

I use both and I even use the float checks in my weapon BP. It just depends.

[lofty rapids]

ya theres so many ways to do the same thing usually when it comes to a program

it's really preference most often

[void crescent]

Also I think you can use the gameplay ability system for this just fine but it's probably a bit of overkill if you just start with UE.

[lofty rapids]

|| var == 0

[frosty heron]

This is quiet abomination

promising that jump can be pressed again after 0.75 second

what happend if your character fell down for more than 0.75 second? It can jump in the air?

The default third person already implement jumps, if you want to take a look at it.

[lofty rapids]

i mean ig you could make the timer start on landed thats another way if you wanted to do that ig

[frosty heron]

is there a specific reason to do that?

[lofty rapids]

idk i don't need to do that, they wanted a delay on jump or specifically a "cooldown"

[void crescent]

I don't think this should be necessary.

[frosty heron]

pretty sure he is addressing the wrong problem.

looks like anim blueprint setup problem to me

JumpStart -> Jump Loop -> JumpEnd

check TPS template for implementation.

[void crescent]

I think the animations that are posted in the video just take a long time to finish (longer than the ones from TP template). In that case I would not wait until the JumpEnd finishes (in third person template this is already done fine).

[lofty rapids]

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

[ivory vapor]

I take it back, I have one last issue with this branch... I already have a fix in mind but that's not the most elegant imo so I would have liked to know your opinion and if you would have an idea since you were great at seeing issues in my BP earlier.

This branch make it so that if a NPC leaves the box the player is currently in, then the npc becomes invisible. Which works great for floor to floor movement. But it would also set those NPCs invisible if they leave the ground level for the outside of the house, leaving them indifinitely invisible unless they get in the house again.

My fix idea would just require another actor box collision that I would manually put at every exit point of a building to set actors visibility back to visible. But maybe there's something more economical I can't think of.

[little moat]

https://blueprintue.com/blueprint/dx_8pu2q/

Could someone help me understand how this code I made works?

I took a big ass break and I forgot a lot

[lofty rapids]

looks like your using velocity to detect where an actor may possibly end up, then using the numbers (in an array for some reason, that will forever grow i think) to calculate if the movement is a collision

looks like some sort of predicted collision detection ?

[little moat]

Oh I kinda got it

I'm getting a future point by using velocity x time + actor location and adding it to an array of future locations. Then I use that array to compare that do the other actors collide with the current NPC's future location

But I'm not sure what's wrong with it

[lofty rapids]

well i would start with does the event run ?

then check if the cast is failing

[lofty rapids]

so whats the logic behind turning them invisible when they leave but the player is in the box ?

[lofty rapids]

theres also a leek if you never clear the array, it will just keep growing

and if in the array there is the right number, it will say collision

so once it finds through math a collision, it will most likely always get that

unless you clear the array at some point

[lofty rapids]

possibly what would fix the floor traverse problem and solve this issue would be to only check if your inside on overlap begin, then on end just always making it visible ?

basically just taking the branch off the overlap end

but keeping it on begin

this way when they walk in and theres a player inside the thing they go visible, but on exit no matter what they always show

[snow halo]

hi, i hava a question, i have 2 scenes, and I wanna find which is closer to the player, should i be adding x+y of right scene and x+y of right scene?

[blissful grail]

Even better - there is a node "Get Distance To Actor"

[inland walrus]

What method should I use to make this concept art 3D UI?

eg.. when the player hovers over a 3D letter, it will move upward and it's clickable etc

not many 3D UI video guides out there using actual 3D objects

[snow halo]

but Im dealing with components

[ivory vapor]

But let's say there's 3 floors (ground, upper and "uppest", or 1 2 and 3) and player is on floor 1, with that logic, won't a npc leaving floor 3 to floor 2 still appear? Or I'm not sure I picture it the right way

[void crescent]

That's what I meant previously as I was not sure how you would deal with npcs outside any box.

If you would just turn them visible as soon as they are outside a box then you can just make them visible if they leave a box in any case (which would turn them visible on stairs).
If you would turn them visible as soon they are out of a building you can do it with your further box collision.
If you would turn them visible only if they are on the same zone (like in the same box or together outside of any box) then I think I would gather them in some kind of array and uninvis them when the player leaves a box. Or lazy but most likely slower if the player leaves a box do some getallactorofclass and some if not overlapping with box make visible.

[ivory vapor]

Well, best case scenario if I could, I would ultimately like to make all the outside of a house masked or black so you don't see it when you go inside the house and you see only the house interior even if the camera is physically outside. (I am not asking for help for that here) But I am still trying to find a way to do that. But even if they're not distinguishable I think, as sanity check, the actors leaving for the outside should reappear.

Turning them visible when they leave whould make them appear between every two box no matter if they are on the same floor than the player tho

so appear in the air if they are upper

[void crescent]

Is there a reason why you don't just use a CullDistanceVolume?

[blissful grail]

Components are just going to be actor position + component position. Or you can use the world location of the component. But still, there is a distance node for general locations as well. It'd look something like this. If it is a hot path, use distance squared.

So you'd just get the distance from your players actor location to the component's world location. Then do it again with the other component you are comparing. Then just compare the results.

[void crescent]

Ok CullDistanceVolume works only with static I think. Sry.

[snow halo]

Ok I made this but result is always going to be scene_rock_right

(tried this with event tick)

its always gonna be loaded on scene right

[lofty rapids]

maybe something like this ?

[lofty rapids]

so this isn't working ? thats interesting this should work unless they are equal distance

[snow halo]

I move around and result always favors the right

oh I know why

I just realized that the vector data remain unchanged, they dont update

wait, I have this function on tick, so they should update

[lofty rapids]

did you update the function to return two values ?

because your not returning two values above in the picture

looks like a different function

[lofty rapids]

and are you getting good numbers for the distance ?

does the math make sense ?

[snow halo]

Im not sure, its ticking but the values arent changing

[full badge]

are you sure the character variable is set

[lofty rapids]

any errors when you close it ?

[snow halo]

nope, not at all

so this is what im doing

scene_left + scene_right

i begin play

I go close to bed, circle around it, move around

[lofty rapids]

you can figure out if your on the left or right with maths as well

but i wonder why this isn't working

[snow halo]

everything remains unchanged

[snow halo]

oh errors, I actually got many errors just now from this function

[full badge]

then you probably didn't set the character variable

[lofty rapids]

accessed none ?

[opaque geyser]

Sorry, not really sure where the right place to put this is, but does anyone have any experience with the Mover plugin. (Eventual replacement for the CMC system). I'm trying to make a first person character, and there are only 3rd person examples built in, so I'm quite lost and confused! 😅

[snow halo]

its working, character was not valid✅

[blissful grail]

Don't bother with mover yet unless you are already comfortable with C++. It will be quite some time before it actually replaces CMC. Mover is still highly in development.

[ivory vapor]

I don't know about them

I'm pretty new to game dev and Unreal

[snow halo]

unfortunatelly it still always teleports me to right side socket 😂

always

[lofty rapids]

but your getting the right numbers now ?

[snow halo]

print string changes value now at least

[opaque geyser]

Is it that rough still? Working on a project with gravity manipulation, and that involves rotating the capsule a lot, which from my understanding CMC does not allow...

[blissful grail]

Yes, still pretty rough. CMC now allows you to change the gravity direction vector.

Capsule is still upright though.

https://dev.epicgames.com/community/learning/tutorials/w6l7/unreal-engine-custom-gravity-in-ue-5-4

[opaque geyser]

Yea, I've been using that, issue is doing so just snaps the character to the new orientation for gravity, but I wanted to smoothly rotate the capsule so it a smooth transition between gravity zones rather than just snapping, is there a better way maybe? (The snap is really jarring from a first person perspective)

[blissful grail]

Couldn't say. I've never had to deal with this kind of stuff. There aren't many resources on Mover itself. So you'll have to just explore it yourself. Most of the people I know that have knowledge on it live in #cpp or #multiplayer.

But overall - still pretty rough.

So if you do need it, then you'll just have to dig into the source yourself unfortunately.

[visual ember]

"find closer location" yet you return one that is larger, don't you? if left > right then return left. shouldn't be return right? just quick looking at the nodes, wasn't following other messages

[opaque geyser]

Fun, lol, that's a pain, being limited on capsule rotation is gonna be pretty impossible to overcome in order to make it work, so I guess I'll be doing some digging

[void crescent]

CullDistanceVolumes can provide you invisibilty ... for static meshes. If you set a CullDistanceVolume with some small values every static is hidden as long as you enter the CullDistanceVolumeBox. Usually culling is used to avoid that something thats hidden by a wall is rendered but the CullingDistanceVolume would even work with manual settings. Anyway skeletal meshes are not hidden so you can't use it for your NPCs (probably you can use it to hide the world if you enter a house.

Anyway about your scenario. I think I would keep most of the blueprint that you already use. If any NPC is leaving a box they should turn invisible. Then I would use a further box actor that covers the hole building. If any NPC is leaving that "OutsideBoxActor" then add them into an Array of actors. If they enter the OutsideBoxActor again remove them from the array. If the player leaves that OutsideBoxActor turn all actors that are currently in the array visible.

[ivory vapor]

Wouldn't small boxes used to set visibility of overlapping actors to visible at the exits of a building be more flexible? Especially with buildings with more complex shapes?

[void crescent]

The problem with the small boxes is that you can pass them in both directions. You would get an overlap end event if you enter the house and you would get one if you leave it. Should be fine if you do a further check if he's overlapping with some box actor as well.

[ivory vapor]

Well the overlap events of my existing colision box for the floors don't include that already?

in the way that it sets visibility depending if the floor is overlapping with the player

[void crescent]

As long as you don't get some race conditions (like simulatan overlap start of one box and overlap end of the other box) you should be fine.

[ivory vapor]

I think it does, I just waited in the bottom floor for an npc to leave and disappear and a bit later an npc just popped into existence by passing through the entrance

I think it's the same npc

[blissful grail]

To be fair - most of the complaints I hear about Mover stem from the networking side of things. So singleplayer might be okay, but still rough. I'd imagine for SP, it'll become much more ideal over the next couple releases.

[void crescent]

So it's working?

[ivory vapor]

Yes I implimented it and it's working, I had to find the correct spot for the new box so it doesn't get overwritten by the floor box if it's too close but it works

[snow halo]

I replaced the < to >

still nothing

same socket is enabled

you know what? I'll just create 2 collision boxes

[lofty rapids]

and how did you get these left and right variables are they straight from the component on the left ?

because i don't see why the logic would just not work

logic is pretty sound

maybe a restart of the editor

might be some kind of bug or something

[thick gyro]

Hello - I have a silly question - I'm just learning UE5.6, and I've been going through the default "combat variant" of the third person template. The one thing I can't really track is what sets the life bar onto the so called BP_CombatCharacter? it is exposed as a variable with a default value of none, and I can't see anything set it? I'm sure its just something obvious but I like to understand stuff

[astral summit]

If I have a widget made a long time ago, I just want to put it in the foreground so the player can see it. How do I do this?

[lofty rapids]

is the widget a user widget ?

i would probably make a user widget, add a canvas

then plop your widget in if you can

then you can create widget, add to viewport

[astral summit]

Yes, user widget.
I don't want to recreate it because it contains important variables.
So I just want to put it at the front for the player to see.

[lofty rapids]

^

you can do this anywhere i prefer the HUD class

but you can put it on the controller, the player, different bp's

depends on when you want to interact with it

add to viewport is what makes it actually show up

[astral summit]

Maybe I didn't explain the question well.
I just want a node or method that will put the user widget on the front of the screen.
Something like "SetZOrder"
And I don't want to recreate the user widget, because the user widget I have has important variables.

[lofty rapids]

oh ok so the widget is already on the screen ?

it's just not in front ?

[astral summit]

YES

[lofty rapids]

so is the problem other widgets are over it ?

[astral summit]

Yes

[lofty rapids]

well i know if it's the last thing added it will be on top

so maybe just make sure it's added last

[hollow pond]

@astral summit does adding the widget to the viewport again (not reinstantiating it) move it to the top?

[astral summit]

You gave me an idea, to delete the widgets above it, but is there a way without deleting the ones above it?

[lofty rapids]

you can most likely remove it then add it again, but i would just add it in the right order to begin with

[lofty rapids]

don't add to viewport untill after the other ones

the order they are added i think matters

[hollow pond]

yeah. you can create the widget and save a reference to it, then add it later. or you could try re-adding it to the viewport, my hunch is that'll effectively bump it to the top

[astral summit]

When I first created a widget, it displayed in top correctly without any problems.

However, after adding more widgets, at some point I needed to push one of them to the top.

[lofty rapids]

i would make a function

[astral summit]

@hollow pond @lofty rapids I think the solution is to either delete the widgets above it or recreate it and moving the old variables to the new one. Right?

[lofty rapids]

idk if that might reset your variables or not

[astral summit]

I don't think this node will work.

[lofty rapids]

did you try it, because it should work tbh

pass the reference of the widget you want to bring to the top

[dark drum]

Removing from parent and readding is the way to go. I've done something similar to reverse the order widgets are displayed in a vertical/horizontal box.

(Get children, store in local var, remove all children, reverse local var, readd to parent was my use case)

[lofty rapids]

from what i understand your variables are safe with this way

[maiden wadi]

It will not affect variables. It's the same object. So unless you set something on Event Destruct, they'll be the same. In fact you can edit them even while the widget is not added to a parent as well just like any other UObject since that's all it is.

This is actually one reason why delegates can be bad for widgets if you don't unbind them properly. Make a bunch of widgets, bind a bunch of stuff to them, then remove them away and the bindings will still run.

[dark drum]

I've had this happen a few times where I've forgotten to unbind and get confused when the logic still runs after they've been removed from the screen. 😅

[astral summit]

Interesting I will try it, thank you

[lofty rapids]

i like reusable functions, in this case since you may want to move a different one to top at some point

[lofty rapids]

i didn't know this, something good to know i don't use bindings very often i update through events or functions i feel it's more efficient but i do use it sometimes and i've tried it

[maiden wadi]

In Red Solstice 2, we had some insane delegate calls on our buff widgets. Mostly anything that affected any stat would cause a refresh, and so would call things like 20-200 times a frame for each buff widget(like 30-60 on screen at any time). That was the same day I stopped being so insanely pro event driven. Doesn't always work the best even if it does most times. 😄

[autumn pulsar]

man, making a health system is more complicated than I thought lmao

[dark drum]

It depends on the sort of game but yea, it can get complicated. 😅

Whats the best way to have teams. Im creating a baseball game that has 6 different teams. I want to store the team name, image, players and ratings all on one variable that I can access. Should I do a structure?

Hi I have a problem with this function 🔧

Im trying to get the player to sit and sleep laying down on bed in the right rotation 🛌 💤

but the rotation always gets rotated to whatever my camera position was the last time I clicked. 🎦

[last peak]

You set rotation to 0 , 0 , 0

[snow halo]

yes but 0, 0, 0 doesnt do anything

in fact even if I put it to 0,0,90. It still changes based on the direction in hitting it from

▄︻デ══━一💥

with my camera line trace 🎦

[last peak]

I dont get it

How is it supposed to change direction if you set rotation to 0 0 0

[snow halo]

thats why I came here, Idk either

[last peak]

your linetrace is not even connected?

Also why are you rotating the capsule instead of the actor?

[snow halo]

So the player attaches himself to the bed based on line trace origin

and at the same time line trace origin + whatever set rotation I add to it (I think)

[snow halo]

I tried to rotate the mesh, and it didn't work. But I will try actor instead ✅

I wanna do this

[last peak]

Sry man .... your pictures dont add any clarity whatsoever ...

so you want to do 4 linetraces?

Why?

[snow halo]

no

no matter the direction im hitting it from

my game is 3d, i have a camera 🎦

no matter the angle im hitting this bed

I don't want this to be a factor that changes how my body sleeps

I can't sleep like this while half my body is floating

I want to be able to go on the bed, CLICK it, and then immidiately take the right position. ✅🖱️

Line trace angle shouldn't affect the body sleep rotation ❌

[last peak]

Just set the players rotation to the beds rotation

[snow halo]

I also tried that 🤔

but Im probably missing something 🪲 ⚙️

[snow halo]

Like this, right? 👇

🤔

still the same problem 😢

[last peak]

Your still rotating the capsule .....

[snow halo]

Still the same problem

😂

but again, maybe Im **still **missing something again

[last peak]

I mean what do you expect to happen now ?

Now you have a fixed rotation right?

0 0 90

[snow halo]

yes

I guess

This needs to happen

[last peak]

what happens if you set it to 0 0 130?

[snow halo]

same thing

it still changes rotation based on the angle which im hitting it from

angle shouldn't affect anything

player should always sleep with his head on the pillow 🛏️ and his legs on the bottom wooden end

[dark drum]

Is your character set to use the control rotation? (Yaw)

[last peak]

Try to set movement mode to flying

[snow halo]

same result.

[last peak]

When did you set it to flying`?

instead of your none ?

[dark drum]

How do you handle your normal look logic?

[snow halo]

Oh I forgot the spring arms

[fiery dragon]

I have an issue with calling an blackboard in my child controller to acces the behaviour tree

can someone help me with that?

As was referring to the player input side of things.

[snow halo]

player character code?

[dark drum]

Yes

does anyone know why the two bone IK is just straightening my arm completely while playing a pickup animation? I still need it to play the animation normally just have the hand go towards the item and get as close as it can without stretching the character. I've attached the animation blurpint and what its doing

this is the normal animation playing without two bone IK

[lunar sleet]

Try #animation

[odd compass]

oh yeah myb

[uneven crest]

Is there a way to end a line trace at a certain x position once it reaches it?

Can i just split it?

[lunar sleet]

Just set the distance of the line trace

How

[true marsh]

Anyone happen to know how Asset Registry will sort assets? If I search for a DataTable, if it is index 15 now, will it always be index 15 in the future?

From my print strings incrementing the index from 0 it seems a bit random as it starts with older DataTables, with some others mixed in, not sorted by name, ect.

[trim matrix]

ive made this minigame manager bp that randomly selects a minigame from a data table, and shows an explanation screen, then sends the player to the level to start the minigame, its slightly working rn but when i play the level that has the manager bp in it, the widget dosnt always show, i have to exit out and hit play again for it to show. the ui for the explanation screen is basic

img 1 is what it looks like at first then when i hit escape and hit play again it works

[trim matrix]

now condensed into this in the minigame manager bp, it still dosnt appear each time

[halcyon heath]

I have a light system that uses structs at runtime to make changes to values. If I wanted to make a change to one variable at runtime and keep the other variables to what they've been set to on construction, is there a better way than to connect all the unchanged pins for everything I don't want to change?

All this does is turn the light on and off when I jump, but notice I have to connect all the other pins lest they revert to their default values

[austere ingot]

does anyone know how to make a character react to getting hit by a vehicle similar to pubg? hitting a player is a brick wall right now 😦

in multiplayer

[full badge]

try use 'set members in' node

[halcyon heath]

Thanks! I literally just saw this answer in a youtube comment on a video with 1k views

[sacred canyon]

if I got an actor that has a bunch of scripts to do on begin play, then I got hundreds of them in a map, is there a way to make them "take it in turns" so that they dont all do it on the same frame? currently I use a delay with a random range but Id imagine theres a better way. once the scripts are done the game runs fine but theres a big stutter at the start from them all doing it

[frosty heron]

might be easier to just implement loading screens and unload the loading screen once the actors are ready

that or you can have an actor manager

basically just one actor that loop through all the actor you like and call the init

so it goes without saying that you can divide the work into multiple frames

[soft idol]

Dose anyone here know how to make a functional VHS tape system? I'm a beginner.

[sacred canyon]

it does do that already actually, since I’m spawning them from another actor, but loops can’t delay of course unless I’m missing something obvious

and yeah I’ll have a loading screen but I’m sure splitting it up would make it load faster

[spark steppe]

you want a queue or a custom loop implementation which supports delays

[faint pasture]

What would a vhs tape system even do?

[soft idol]

When you pick up at tape and insert it into a player it would play a video on a tv with audio

[faint pasture]

Start with getting a video to play in the engine at all

[soft idol]

Ok I already have that

Also if it helps I’m trying to make a system simular to the ones from poppy playtime and Amanda the adventure

[faint pasture]

Do you have generic interaction in your game? Where you can walk up to a thing and press a button and the thing will do whatever.

[soft idol]

I think I might

I have basic interaction where you can walk up to something snd press E and you will be able to pick it up but that’s it

[faint pasture]

Do you have doors, buttons, various things that do different stuff when you press E?

You need 3 things here.

1. The ability to play a video
2. The ability to have items
3. The ability to interact with things

Then, a vhs playing tv is just an actor that, when interacted with, removes a tape item from the interacting players inventory, and plays that tapes video

[soft idol]

In my game I barley have any and mostly just have pressure plates that when I shoot open up a door but I could learn the interaction system with tutorials unless this needs a special interaction system

And I think I get the second part you mentioned

[faint pasture]

You need to get a generic interaction system in your game pronto

Show what your current code is for interaction, starting at the input event.

[soft idol]

this is my interaction system for my character

[finite hearth]

I am out of free GPT credits.

Unreal Discord, GPT: How do I calculate the length of green?

[spark steppe]

#game-math #Trigonometric

[faint pasture]

Ok so you already have a generic interaction system

[soft idol]

Yes I do

[faint pasture]

35 x cosd(75)

[faint pasture]

So just change the interaction interface function to include the interacting pawn ref then the VHS player knows who to check for a tape on

Instead of saying "Thing, you got interacted with" you say "thing, you got interacted with by this guy"

[soft idol]

Ok sound good

[lofty rapids]

does it error when it fails ?

[lofty rapids]

also you want to loop from 0 to length - 1, theres also a node called lastindex

i think it might be picking the random one that is out of range sometimes

so fixing the index should fix the problem

an arrays length is the actual amount of items in an array
because arrays are typically zero indexed, the last index is length - 1

[snow halo]

Hi I have a question

@lofty rapids btw I fixed the bed thing ✅

my question today is this... I can't get my camera to target and focus on the player

this again seems like a simple enough problem

but the camera is going under the landscape but is on the right location horizontally but wrong vertically

then what I tried to do is split this get world location and set world location

and then after I split I try to connect x+y but not z

but still fails

So if I do it like this

camera will go faaaaar faaaar waaaay wayyy out of the map

and I can put something on the Z. like 100-200, still wont work

[lofty rapids]

ok so instead of just leaving z to zero, set it to the cameras z

then you should be able to adjust the height based on the camera z location

[snow halo]

oh it works

wtf

lol I did it, chat gpt is awesome

[sturdy hollow]

Hi i need help with a keybinding issue.
Im using the old input system (Project Settings > Input) and modifying keybindings at runtime using Remove Action Mapping, Add Action Mapping, and Save Key Mappings.

It works perfectly in PIE, but in a standalone or packaged build the changes don't save. Any idea what I might be missing?

[valid anchor]

Hello everyone I has one question

I've created a BP from a static mesh component with a OnComponentHit event inside [and an event dispatcher]

how can I call that even from other Blueprints?
Since I want to do some additional thing from the BP of the level [such as printing text, referencing variables defined on the level, etc]

[surreal peak]

Where are you calling those methods on? Also why are you suing the old system? Are you stuck on UE4?

[sturdy hollow]

im on 5.4 and i dont know how to use the enhanced input and the old input dose what i need

[surreal peak]

You need a reference to an instance of that Actor. Then you can access it.

There is no magic way to get that reference.

And I would suggest not falling back to the LevelBlueprint if you can avoid it.

[surreal peak]

Fair, but it will be deprecated eventually. You would do better learning a few simple steps to use the new one. Either way, you still need to share what you are doing exactly. It's been ages since I used the old system.

[valid anchor]

so I should probably move the bunch of my logic from the Level BP to the BP_Ammo or BP_Target? 🤔

[sturdy hollow]

i think that it saves temorarly since i call this then it sets the correct bind but if i exit then everything resets

should it make a ini file for the keybinds?

[surreal peak]

depends on what you are doing, but the LevelBlueprint is in theory only meant for stuff that is only ever used in that map/level and even then it's most likely that there is a better way of doing it.

[surreal peak]

Well that is only setting stuff on the KeySelector.

Where are you actively applying the changes?

[sturdy hollow]

like i said it saves correctly in pie but not in a packaged game or standalone

[surreal peak]

SaveKeyMappings should already save to the config.

On the other hand, InputSettings are project-wide. It doesn't seem correct to me that you'd be modifying those directly.

If you do that and you test in the Editor, you'd start actively modifying the default settings of your project for the keymappings.

Might make more sense to have your own SaveGame or GameUserSettings object for this.

And saving them there, then applying them back when loading them.

[valid anchor]

Basically, following the gamdev tutorial I've created a "Shoot the barrel"

you launch a projectile
if it its target the target is destroyed and you get one additional shoot
otherwise you lose a shoot

projectile is always destroyed after a certain amount of time

in this way you can play indefinitely for as long as you keep hitting

once you reach 0 shoot, you lose the game and you get a reset

[surreal peak]

Okay, and?

[lofty rapids]

you want to get a bp's values or run there functions from inside the level blueprint ?

[surreal peak]

For that stuff you'd usually have some DamageInterface you implement on a Target Blueprint Actor to deal damage. That way you can turn everything into a target, not only some StaticMeshComponentActor.

And if you want to reward the player with something (here a bullet), you'd want to pass the Instigator (the Pawn/Character) and the DamageCauser (the Gun) along.

Then you can have some managing code in your GameMode or GameState that you can notify about the Target being destroyed, and then forward that notification to both the Instigator and DamageCause.

The DamageCauser can the decide what it wants to do. E.g. +1 the ammo count.

I don't see the need for the LevelBP here at all.

[lofty rapids]

"not everything is guaranteed to be fully loaded when the Level Blueprint's Event BeginPlay executes"

is this true ?

it's what google says

[surreal peak]

Depends on what you call "fully loaded"

BeginPlay calls because the GameState sets its MatchState into "InProgress".

And it calls on Actors that are valid at that time, and on later Actors after they spawned if the world has already begun play.

There is no connection between those Actors. So not a single BeginPlay call in an Actor is necessarily guaranteed to call before another.

Unless you literally spawn one Actor within teh BeginPlay of another fwiw.

[stone field]

I would go so far as to advise people to avoid Level Blueprint like the plague, since anything done there referencing level actors will not be useful anywhere else : )

[surreal peak]

There are useful cases for it fwiw.

But I agree that almost all cases can be replaced.

[maiden wadi]

That statement is likely a badly phrased point to the issue that things like pawns may not exist yet and such. It has nothing to do with "being loaded". Everything is loaded unless you're explicitly async loading them with softrefs. But certain things are ready early and run their beginplay as such, and some things like pawns may not be created yet.

[storm solar]

I have an actor that is used to create spells. When the spell is activated it creates a sphere overlap actor that checks who gets hit. The issue is that the actor itself is a 3d object and other actors will collide with hit. That can cause them to get stuck or stand on top of it (like the second picture).
How do I make my actor spell mesh collide with objects but not impede or alter other actors movement?

[dark drum]

Change the collision so only overlaps the things you care about and ignores everything else. You currently have it to only overlap pawns but this still blocks on other channels.

[grave venture]

I'm implementing Dash into my character

Everything works fine, except for one thing I can't think of how to do.
The character has Maximum number of dashes available (3) and after using 3 dashes it resets to Max dash Count

I want to make it so that it has auto refresh, let's say in a second, if player uses 1 dash only (Out of max - 3 Dashes) it will reset to Max dash count again

There's other code present obviously, but I think this is the important bit, if something I can screenshot more of it

[lofty rapids]

so after you use 3 dashes, you run this event to reset it on a timer ?

[grave venture]

Yeah, whenever the player uses 3 dashes, it goes on a cooldown.

But the cooldown begins only after 3 dashes are used.
I want to reset if, for example, dash was used once, but hasn't been used after that (for 1 second or two second, for example)

Right now, it remembers the number of dashes used indefinitely

[lofty rapids]

how so you want like a refill ?

on a timer maybe ?

[grave venture]

Timer yes, I'm thinking if the dash hasn't been used for 1 second or 2 seconds, Max dash count will reset to 3 again

[lofty rapids]

so create a timer on when a dash is used, set it for one second, check that it's still one used (which you'll need some variable), if it's still one used refresh it

you can also just logically make it fire on the first one

[surreal peak]

Are the DashCooldown and that 1 sec "delay" the same variables, or will they be differently long?

[grave venture]

They'd be the same duration

[surreal peak]

Then you can just call that DashCooldownBegin every time you execute your dash (or end your dash w/e)

Save the TimerHandle at the end and reset it before starting it again.

DashCooldownBegin -> GetDashCooldownTimerHandle -> Reset -> SetTimerByEvent -> SetDashCooldownTimerHandle

[lofty rapids]

then it would fill if you used 2 as well, but would be less altering

[surreal peak]

Well as far as I understood, they want to allow spamming the dash and whenever the player hasn't use a dash for 1 second, they want it to reset.

Since the cooldown for any of these is the same (that's why I asked) they can just keep calling that method.

Once the player reaches 0 Dashes, they can't dash anymore anyway, and the timer will fully run through.

If the player dashes twice, it will reset the timer twice, but if they don't use the last dash, the timer will also get the chance to fully run through and reset.

same with just 1 dash

[humble wigeon]

Ok, I'm confused, I hope someone can help me on this.. I feel like I'm close but I don't really know.
I'm trying to create a button-mashing game where two players need to button-mash to win a race. I'm calculating the button mash rate (over a 1s window) every tick, clamp it between 0-1, and I use that on a lerp node where A is the Base speed and ***B ***is the max, and I ***FInterpTo ***from currentSpeed, and finally I use the **output **to set the Character MaxWalkSpeed property. I figured that setting the MaxWalkSpeed for the Character every tick is not the only thing I need; I need to keep calling "AddMovementInput" until the **MaxWalkSpeed **is below a small value, that way I can see the character slowing down.. For some reason, though, it doesn't work..

[grave venture]

Thanks a lot man, simply hooking this in the end seems to do the trick ❤️

[grave venture]

Nope, scrape that 🤣 I was wrong

Or I'm implementing it incorrectly so will be back later

[grave venture]

I want it to reset on 2 as well

[lofty rapids]

you would have to like mentioned reset the timer each time using the handle

[grave venture]

Thing is, I'm new to Blueprints and as much as I understand the logic behind it and before posting, I understood what I Needed to do, I'm not sure how to translate that into Blueprints

[lofty rapids]

something where you take the forward vector and multiply it by the speed for the amount of movement, similar to velocity ?

[lofty rapids]

here in this picture you can right click return value and promote to variable, this is the handle

then before the timer runs, add an invalidate timer by handle node and plug in the handle

so every time you press it the actual time will reset

idk if that will fix it as you may not be running it at the proper time, but definately what was mentioned

[humble wigeon]

And this amount of movement, where would I use it? Are you referring to the Scale Value in the AddMovementInput node?

[lofty rapids]

you could use the scale, or just multiply the forward vector by a value

you may need to adjust your speed for either way you choose

idk if will help, but it's worth a shot

personally i would go with a manually movement

you can just build up a bar, and it goes down, and that would slow you down as well

but thats if you handle it manually

[lofty rapids]

this movement runs on tick ?

[humble wigeon]

Setting the MaxWalkSpeed variable in the Character Movement Component also communicates with the animation blueprint so you get the smooth run-to-jog-to-walk sequence as you decelerate (or rather, as you bring the MaxWalkSpeed down), simply changing that will also slow down the character movement

I tested this, by setting the MaxWalkSpeed in the blueprint to a low value and the character simply goes slower and you get the animation to match

[humble wigeon]

yeah

I just need to slowly bring that value down over time once the mash rate is 0..

[lofty rapids]

check your values if you can in a widget or with print strings

or even with debug ig (altho i hear it can be inaccurate)

[uneven crest]

I have a parent actor and made multiple childs off of it. How can I get the code from the parent to continue onto the child actor

[lofty rapids]

right click the event, and click add call to parent

[uneven crest]

In the parent or child?

[lofty rapids]

in the child

[uneven crest]

I dont see any of the events or functionns in the child

[lofty rapids]

so add the event you want

[lofty rapids]

https://blueprintue.com/blueprint/f6riy51a/
yes as you can see here i used a drain

https://streamable.com/94b43h

theres probably a few bugs with the code, but the point is the drain anyway

you probably wouldn't do like i have where you can hold down the key and it doesn't drain lol

but thats the point of the boolean, so you can change the logic with ease just set the boolean at the right time

[surreal peak]

I mean, I did tell you to save the TimerHandle of the SetTimerByEvent node and to reset it before calling SetTimerByEvent.

That's 3 nodes and the creation of a new variable involved in that. I'm sure you can figure that out.

[humble wigeon]

I'm gonna give it a go. Looks perfect!!

[lofty rapids]

well you probably want to use started instead of triggered so they can't hold the key down

theres a few flaws just mentioning it i didn't test or take much time, just threw it together to show you how i'd do it as an example

[grave venture]

I did like this, and it seems to be working fine!
I'm not sure if this was what you recommended honestly, so can you please give a feedback, maybe this ultimately sucks or is a Very bad practice?

[surreal peak]

Hm, that is not really what I meant, no.

idk what you need the second timer for

All I suggested was this

ClearAndInvalidate is the function to reset the timer.

Called on the saved TimerHandle (Var)

Just give it a better name than what I did (Var).

[trim matrix]

is there a way to make it so the random selection dosnt repeat the same one it selected(aside from just adding more minigames bc im just testing with a few rn), rn it will select a minigame, then the flow loops back after the player plays the minigame, and the next one selected is the same (not everytime)

[surreal peak]

You'd need to maintain a copy of the Array and remove the item that was chosen last time.

Once it's empty you can oveerride it again with the fully Array retrieved via the DataTable node.

That copy must, of course, live somewhere where it doesn't get destroyed when changing levels.

In Blueprints that is most likely going to be the GameInstance.

[trim matrix]

how would i do that? sry i feel like i slightly get it but im confused

[surreal peak]

Do you have a custom GameInstance Blueprint?

[trim matrix]

no but i can make one

[surreal peak]

Yeah, then that's the first step. Don't forget to assign it inside the ProjectSettings.

Inside that Blueprint, you can make an Array property of type "Name".
You can call it something like "AvailableMiniGames" or so.

[surreal peak]

Ya, then add an event called "ResetAvailableMiniGames".

And in there, use the "GetDataTableRowNames" and set the property you just made with that.

[surreal peak]

Then create a function (not an event, cause you need a return value), called "GetNextRandomMiniGame" and give it a "Name" Output.

In there you want to use the "Random" node (or the "RandomIntegerInRange" from your setup) to retrieve a random element of that property.

Best would be to store that in a local variable (local to the Function).

Then call Remove on the "AvailableMiniGames" property passing in that local variable to remove it, so it doesn't get picked again.

[lofty rapids]

so you want random, but not all the same numbers ?

[surreal peak]

After that you can check if the Array is empty, and if it is, call "ResetAvailableMiniGames" to refill it.

[lofty rapids]

don't repeat is what your looking for

[surreal peak]

Then return that local variable.

[surreal peak]

And the last thing you'd wanna do is to add the "Init" event to your EventGraph (that's one coming from the GameInstance class, similar to BeginPlay of Actors and Components) and call "ResetAvailableMiniGames" there too.
Otherwise, the array would be empty at the start.

You can then, where you currently do your random picking, get the GameInstance, cast to your custom one and call "GetNextRandomMiniGame"

[lofty rapids]

usually i handle this with something like an array of all the numbers, then shuffle it, then inc the index untill it's done

[surreal peak]

Just let them implement one thing first.

It's just confusing if you throw in another one now

Once that is working for them you can suggest changes

[trim matrix]

so next thing i need to do is go to my first random cast to the instance and check to see if its empty if it is set it to the value from the instance?

[surreal peak]

Show me the Get function when it's done.

Then we can talk about the usage of it

[lofty rapids]

you can also keep track of last, and if last == current then try again

but a shuffled array i think is what you want

[trim matrix]

this? or adding to where i have the first random

[surreal peak]

Gimme a sec

[lofty rapids]

oh i see, your going to remove from available minigames ?

[surreal peak]

You can do it with shuffling and keeping track of the last index too. It doesn't matter for the first implementation for them.

[lofty rapids]

makes sense

[trim matrix]

oh ok

now to check if the first random is empty?

[lofty rapids]

it shouldn't be empty

[surreal peak]

Hope that makes sense. I colored parts that you should pay attention to.

There is another approach where you wouldn't empty and refill the array but simply keep track of the last Index you accessed, incrementing it every time you want the next entry and going back to 0 if you go beyond LastIndex.
And every time you go back to 0 you'd shuffle the Array to make the next "loop" different than the previous one.

They both result in the same fwiw.

[trim matrix]

which should i do?

[surreal peak]

Whatever you feel comfortable with

[lofty rapids]

"Each delete triggers array resizing"

[surreal peak]

Yeah, but this is called once every blue moon.

It's not called on tick or similar. Before this part causes performance issues, everything else will.

For a beginner this doesn't matter.

[lofty rapids]

it's probably negligable on small things

[surreal peak]

Here is the alternative version:

Init just doing this:

The Reset event is thus not needed anymore.

fwiw, the IsValidIndex check should also be part of the other solution, in case you left the DataTable empty.

[vagrant slate]

Anyone able to get javascript running in the web browser widget? (such as putting an html file in with a script tag that runs js). Or get an include with javascript to go with a packaged build? I am struggling to figure this out for some reason.

[lofty rapids]

ya it runs

what are you trying to do ?

[vagrant slate]

I have a minigame I built with html/cs/js that I'd like to embed via a browser widget

I can get it to work in play editor window with a direct link to it

[surreal peak]

Buh, I wonder if the BrowserWidget got any updates the past years.

[trim matrix]

so dont do it this way?

[surreal peak]

Kira, I wrote that it's an alternative.

[lofty rapids]

wdym by this ?

[trim matrix]

ah

[surreal peak]

You can keep that version, or use the other.

It makes no difference for you.

[trim matrix]

sry misunderstood

[vagrant slate]

If I link the browser widget directly to the html file it will run fine when I run a test in a new window but breaks on build. I've seen that you're supposed to be able to put it in the content folder and reference that way but it doesn't seem to want to be included in the build despite messing around with package options

[surreal peak]

I don't know what RemoveItem does in Blueprints, but in C++ I would probably call RemoveSwap or whaver it is called, so the resizing stuff wouldn't even apply there.

[vagrant slate]

I've also tried just including it in the BP via load string. I can get it to run the html this way but it won't run any js

[surreal peak]

So the versions are most likely the same in performance. If Blueprints use something else for the Remove and it resizes the Array then the alternative is slightly better in performance. But it's really not that big of a deal since you call this only once in a whil.e

ive added the cast to where i have the first random

[surreal peak]

Replace the red marked nodes with a call to "GetRandomNextElement" on the GameInstance variable you made.

[surreal peak]

Try it out and let me know if it works

And make sure you actually assigned the custom Gameinstance BP in your ProjectSettings

It's easily forgotten

i'm using a server so it's localhost

but i think what you want is to include the file after you build in the folder

[vagrant slate]

I got localhost to work with node- but I don't want the user to have to do any setup- does your approach require the end user installing anything?

[vagrant slate]

I did try this but I could try harder to see if I could get it working that way

[trim matrix]

ty that seems to be working now, ig ill see when i add more minigames for sure lol

[lofty rapids]

so far yes, but there is a way to automat it i just have not done that yet

[lofty rapids]

do you have c++ or just bp ?

[trim matrix]

i just thought of something, alot of the inputs for the minigames unless already part of the third person charcater bp use this setup or some form of it not always on tick. is that bad? ive only been able to figure it out like this w chat gpt helping bc setting like actual input events wasnt working how i wanted/i couldnt get it to 💀

[surreal peak]

That's more or less the worst possible way you could have done that haha

[trim matrix]

figured 💀

[surreal peak]

Please learn how EnhancedInput works

[trim matrix]

i have a little

[surreal peak]

All you need is usually one InputMappingContext Asset for whatever Context you care about. And then an InputAction Asset per Action you want to perform.

Then you add the InputActions into their InputMappingContexts and assign one or more key to them.

[trim matrix]

just not with like having the same buttons be multiple inputs before, all ive rly done is just adding new inputs to a mapping

[surreal peak]

And set the InputActions themselves to the correct type and add triggers and modifiers to either them or the InputMappingContext.

Then you can add the InputMappingContext(s) to the LocalPlayerInputSubsystem or whatever it is called.

And that's kinda it.

i'm looking at something right now might be able to get this to work, packaging a project to see if i can get the saved directory, then you can open url

i need this to work myself, because i wasn't planning on shipping with a server

[surreal peak]

You should really fix that sooner than later. This is a terrible setup. It doesn't allow rebinding and it uses Tick for something that is often merely a single action.

[trim matrix]

so something like this would be better?

[surreal peak]

Yeah, the Triggered pin though, but yes.

What do you need the BeginPlay boolean for?

[trim matrix]

bc i have a countdown i dont want the player to be able to score while its counting down

[surreal peak]

Right, okay.

[trim matrix]

doing it like this dosnt increase the score, nothing happens

[vagrant slate]

it's all BP

[surreal peak]

That's not enough info to help you.

• Where is this code located?
• Did you add the IA_mg000 to an InputMappingContext?
• Did you add the InputMappingContext to the Subsystem?

[uneven crest]

I have this code in a parent actor. How can I have it in the child actor?

[trim matrix]

located inside a actor bp for the minigame, yes, and yes

[lofty rapids]

and the game works without a server ? you can open it up in a browser from file explorer ?

[vagrant slate]

correct- I got a demo js working so it seems to be something related to my js itself

[lofty rapids]

ok

[lofty rapids]

ok i was just waiting for project to package, but i was hoping to put the file in the main directory then just open the url

[lofty rapids]

how did you link to the file in the package build ?

ya i used launch dir, to format the url and it works great

need to switch it when developing but other then that it's fine

[vagrant slate]

I tried a bunch of things- but good news- it does seem like there is something that unreal just doesn't like in my js- it may be related to making changes to the window size or related

[surreal peak]

Random Actors in the scene need Input enabled to work with Input.

By default only the PlayerController and the Possessed Pawn will have that.

Try calling EnableInput (via the PlayerController) inside of it.
