I... I really have no idea I'm just a simple environment desigber with 0 knowledge about blueprints... ๐ ๐
Can you like... Can i dm you to work on it together, if you got time?
I've been trying to fix it by myself for 3 days and couldn't do it so... i know that i really need someone elses help for this one
@fleet ermine
when i play the game alt + p my fps decrease in the time..
whyy
fleet cedar
@fleet ermine not sure sorry... can you just use a diff name ๐
fleet ermine
@trim matrix I don't have the free time... but have you tried to just attach the camera to the character and then switch between the cameras by putting a bounding box on the door entry to that when the character hits the box it switches to the other camera which is also attached to your character...
@fleet cedar I can't because I'd have to redo everything... I would have done that by now it it were just that easy... I just don't know how or why I can't name it that name...
trim matrix
Well the way my game is going to be it won't work like this unfortunately...

I get inconsistent FPS depending on what window I'm on whenever I run it.
fleet ermine
@trim matrix ok your video card is a 8gb card and your processor is a quad core running at 3ghz...
@trim matrix Do you have a lot running in the background? Processor cores could effect that a little... for instance... I have GTX 1080ti with 11gb of video ram and an AMD Ryzen 1800X with 8 cores running a 4ghz. but I also have 32gb of system RAM running at 3.2ghz... so differences in the system specs will vary with how they respond...

how can I do this?

I have a widget switcher with a tabbar, when switching through the corresponding widgets they only play their fading in animation once per tab (event construct) but no more if I cycle through them multiple times; what node (or what method) can I use so the widgets play that animation each time they become the widgetswitchers active index?
rocky stratus
Why not call the animation when you switch to said index?
@atomic light
That's what I would do anyway, based on the state of the widget ( or index of your widget switcher ) call the appropriate animations.
nocturne remnant
I'm very surprised at someone using midpoint arrows
Which reminds me ... why is there still that option for graph types to change from the directional circles to diamonds and squares or whatever the hell it is?
atomic light
@rocky stratus But I have the widget switcher and its buttons in the main BP, and each of the tabs has its own widget BP with their corresponding animations, would I have to cast inside the main BP?
rocky stratus
Yeah that's kinda annoying to deal with
I usually just make a reference to the main BP in my sub widgets and set that reference from the main BP
Doesn't really feel proper but it works

Whats going on with this?
i thought i may have been a material instance im using on a bot but i made them thier own instances and its shot
i can only run in editor
its a multiplayer game so this is no good.
cant launch the game in standalone
atomic light
@rocky stratus could you elaborate on that and ping me pretty please
nocturne remnant
Unless I'm misunderstanding, you're talking about effectively having a controller blueprint for the other widgets... which is probably the way you'd want to do it.
So, I'm not sure why that wouldn't feel proper
rocky stratus
Well, passing around references all willy nilly kinda sounds like a bad idea to me unless done properly.
Unless I'm misunderstanding, you're talking about effectively having a controller blueprint for the other widgets... which is probably the way you'd want to do it.
@nocturne remnant More or less, yeah
crimson charm
why cant the players see eachother
rocky stratus
@crimson charm You will have more luck in the multiplayer channel

nocturne remnant
@near yarrow I realize you might have a lot of materials references, but is there any way you can check what happens if you just use the raw materials? My gut feeling is that something isn't getting packaged for the base material and that's causing the instance(s) to fail.
@rocky stratus That's the same kind of approach you take with a player controller... You largely have one thing that's telling a subordinate what to do. You don't want to have fifteen things with references to each other when you can have one thing with all the references. It's going to be far easier to change and add stuff like that.
near yarrow
@nocturne remnant thanks for the tip. i will look for that in the future. for some reason removing the affected blueprint from the level and replacing it fixed our issue
nocturne remnant
@near yarrow I could totally be wrong. But I have had the case where, after moving a material and its associated files inside the editor, it didn't update the reference with the new location. So, I'm just guessing that it's something like that.
cold marlin
Is this where I'd post the blueprint features I've made or is this more of a support channel?
near yarrow
happened to my game instance. i had to go back into all blueprints that referenced it and delete those nodes and redo them
nocturne remnant
Yeah, a lot of times it just doesn't handle moving things around gracefully at all. If you don't have a solid directory structure from day one, or you pull something in from some random/test project, it will find some way to shit the bed and do a bad job of telling you where it broke.
near yarrow
def next time around will have folders on point
i was beating my head against a table for hours after that 
nocturne remnant
@cold marlin generally, it's the, "I don't know what the hell I'm doing" or "oh, God, help, something broke" channel. I'm not really sure if "features" necessarily go into #work-in-progress or not.
cold marlin
@nocturne remnant thanks, I'll have to keep that in mind since code breaks way too often when you are a one person indie developer
nocturne remnant
In case you haven't seen it, https://github.com/Allar/ue4-style-guide has a number of useful suggestions, including directory layouts. Looking for a directory structure is how I found that and consequently wound up here.
atomic light
@nocturne remnant so a "controller blueprint" is what im gonna need? im noting it cause i cant work on it for a while
onyx yew
Is it normal that I cried when my first game ran on my phone
nocturne remnant
Need might be a strong word.
But, consider this arbitrary example:
Let's say you have a lot of "cube" actors and you have four different things that might need to access all of those cube actors for some purpose. Each one of those things could do a GetAllActorsOfClass "cube" or you could create some kind of ObjectManager and whenever one of the cubes is instantiated, it registers with the manager. Then, all the things that need cubes can ask the manager for a list of them.
And if you wind up needing all of the "sphere" actors instead, you could change that at the manager level instead of changing what you were looking for on all four of those requesting things. Or, you need all the cubes and the spheres. The end result being that you're controlling access at one point instead of four, or fifteen, or 738.

How do you get parent level when streaming objects from that level?
I want the name of the level that my end pad is from, so when you reach it, it opens the next level (specified using a name) and then closes the current one that the end pad is from.

is there a way to interrupt a montage or animation?

Delay node is your friend
I solved 2 problems just today by putting in a delay node in both spots, too much was happening in the same game tick, may help ya
grizzled rain
Not in this case
It's not related to tick
But I did fix the same type of issue a few days ago with a do once node in a tick haha
mellow stump
nice
grizzled rain
I guess an easier way to do this
When I unload my level
Is there a way to just reset everything to how it initially was
mellow stump
I take it you're sending variables to a save game?
youd have to clear those variables
grizzled rain
Not involving these actors no
mellow stump
Are you sending anything to the Game Instance? The Game Instance is persistant, it IS your game. Anything there will carry over. Those would need to be cleared
Other than that idk

honest forge
Hello, apologies if this is the wrong channel, could someone help me get my asteroid mesh to fall from the sky as a meteor and spawn a foliage type?
thorn ermine
@honest forge sure , what have you done so far, have you got 'meteor' meshes in the sky already, and a terrain or something to 'collide' with, and then do you have foliage static meshes imported into the content browser?
honest forge
@thorn ermine thank you. I have asteroid meshes and have a landscape setup. I have also created foliage type that my player can harvest which uses the asteroid static mesh.
thorn ermine
@honest forge ok, you can create a blueprint with a static mesh component as the root, using the asteroid mesh, then add a physics sphere around the asteroid and ensure generate overlap events is enabled, add an 'on component begin overlap' event to your blueprint using the physics sphere and assert that the overlapped actor is your terrain ( you can also optionally set your physics channels to make this easier ) . from there you use hit point of your impact from the overlap and 'spawnactor' ( https://docs.unrealengine.com/en-US/Gameplay/HowTo/SpawnAndDestroyActors/Blueprints/index.html ) using your foliage static mesh as class, destroy the current blueprint after spawn. something like that...
@trim matrix at our studio I use it every day yes. both c++ and blueprint.
but i am no master
@honest forge to make it fall, enable physics on the sphere (setsimulatephysics) and use either addimpulse ( good one time burst ) or addforce ( called every tick ) to make it go into a particular direction using physics.
@honest forge come to think of it, rather make the physics sphere the root, and add the static mesh asteroid as a child.
honest forge
@thorn ermine thank you so much. I will be on my pc in a few hours and will try it out and see how I go ๐
thorn ermine
@trim matrix for question 1, of course, we always create base classes in c++ ( actors, widgets, anim inst, game inst, etc ) and then extend and inherit in bp as required. for question 2, i suspect KismetMaterialLibrary is a static library, meant to be used statically. it may be more beneficial to create a BlueprintFunctionLibrary, and do what ever you need to do in there in c++, this also makes it easily available and callable in blueprint. BUT, i see no reason why you wont be able to extend an existing library, you will then just have to use this new library in stead of the old one, to get the new functions.
he he, thanks udk..
ok i see. the thing is though, we can pretty much access anything from c++, but i honestly do not know how to scope function libraries by event graphs per object type. if you remove 'context sensitive' you do get a lot of stuff that have nothing to do with the current graph and blueprint type you are in, but exactly how they (unreal engine) drive which function libraries are available in which event graphs i have no idea.
you may just have to experiment a bit.
and just by looking at the documentation for KismetMaterialLibrary, it seems it has bundled some common functionality into blueprint functions. as far as i know, these functions are indeed available in any blueprint like a character blueprint, as it has to do with creating dynamic material instances, and setting different variables on them. this would typically be something you do in a place other than a material graph.
there are things called material functions. now these have kind of nothing to do with blueprints, and are only available to materials, as they provide reusable shader functions and logic
you also see they do the same. ๐ class UKismetMaterialLibrary : public UBlueprintFunctionLibrary
thanx udk
kind of, but more at Epic.. Kismet is Blueprints' grandpa
it came from Unreal Development Kit (UE3)
nocturne remnant
and if you think that people make terrible spaghetti messes in blueprints .... hoo boy
that's less insanity than another screenshot I found, but it was on wordpress so I couldn't direct link the image
thorn ermine
@trim matrix the time node is a very useful function to drive material animation. panning, rotating etc.. in c++ you can use the tick function's deltatime to drive interpolating | updating values over time. you can then go and multiply these by scalars of course to more finely control their speed.
nocturne remnant
the round value nodes aren't doing it any favors either
thorn ermine
@trim matrix certain material functions like the sine function were designed to specifically work with the time input. if you want to use something to keep state in the game, you could always create an actor, with no real geometry in it, and simply use it ( spawn it in code or bp ) to maintain state, you can also access this actor from bp, and c++ by tagging it, to more easily get a hold of it.
nocturne remnant
http://www.vitamin3d.com/bilder/kismetprogramming.jpg There's a better example. And I'll stop being disruptive with that one.
thorn ermine
yikes
@trim matrix also look at gameplay timers. ๐ https://docs.unrealengine.com/en-US/Programming/UnrealArchitecture/Timers/index.html
@trim matrix i might take flak for this one, but you can, i dunno if you should, but you can get a hold of the world time at any given time.. simply call GetWorld()->GetTimeSeconds(), and you can also even get the last world tick time. DeltaTimeSeconds
it just sounds to me like the function you want could be something that wants to maintain some kind of state wrt game time, from a stateless function. i guess if you are only looking for a number that increases and you dont have to increase it it should be fine. as for delta time i would just be hesitant to use it outside of a tick function.
if you look at something like sine for example, they provide an input to time, rather than getting it from the world time outright.
this makes it the caller's problem, to provide the time, and not the callee.
so the caller can control the time ( or any float value really ) dilation for example, by using a scalar in stead of just assuming the world time.
something like that..
which blueprint editor if i may be so bold?
right... for materials it's a different story, they use what we call material functions. they are not normal blueprint functions.. they are more akin to , well they are reusable shader functions.
๐
so material function you can only create with the material function editor. i suppose one could go and write the shader code directly somehow, but it would be ghastly... also.. LOL
i have not seen it be done yet..
earnest tangle
afaik you can do shaders by editing engine source, but not really an expert on that aspect :)

anyone explain what mean by delta rotator in blueprints?
what exact delta rotator mean
earnest tangle
A rotator object which is a "delta", as in the amount of change

Delta can be considered as Difference
@hollow flame you mean there is a thing called delta rotator? Or there is an input called delta in the rotator?

livid pebble
is there a noob channel somewhere? I just started and have a few questions but I'm guess what I'm doing is fairly simplistic but can't seem to find my answer anywhere. It's related to C++ and Blueprint variable passing
thorny cedar
just ask, if someone can help you will find out
livid pebble
so I created a new project in UE4 (4.25.2) in Blueprint mode to create a random array of hex tiles based on a youtube video I watched. All good thus far.
However, now, I wanted to set the values for the GridX and GridY and especially the Z scaling variable from a C++ class
So I created a C++ class and set what I feel are the correct UPROPERTY and UFUNCTIONS to achieve what I need, but I can't see them in the appropriate context sensitive blueprint
so my question is how do I link a C++ class to an existing blueprint
trail rampart
you open blueprint and reparent it to a new class
livid pebble
did that
Parent class for my blueprint is now displayed as "Level Generator"
and this is the basic header for it: ```#pragma once
#include "CoreMinimal.h"
#include "GameFramework/Actor.h"
#include "LevelGenerator.generated.h"
UCLASS()
class MAPGENERATOR_API ALevelGenerator : public AActor
{
GENERATED_BODY()
public:
// Sets default values for this actor's properties
ALevelGenerator();
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "LevelGenerator")
int32 NumMapRows;
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "LevelGenerator")
int32 NumMapColumns;
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "LevelGenerator")
TArray<int32> Map;
protected:
// Called when the game starts or when spawned
virtual void BeginPlay() override;
public:
// Called every frame
virtual void Tick(float DeltaTime) override;
UFUNCTION(BlueprintCallable, Category = "LevelGenerator")
void setMapSize(int32& rows, int32& cols);
};```
trail rampart
looks fine to me
livid pebble
I mean everything compiles, but when I right click in the blueprint and search for "setMapSize" function it does not appear
livid pebble
no, I can cast to LevelGenerator Class, but no category
trail rampart
can you select function from the cast?
livid pebble
at this point I'm not sure how to check... because I would need to pass something into the exec chain, no?
livid pebble
it doesn't
livid pebble
didn't matter
I might have really borked something along the way
perhaps I will make a new C++ class and reparent again, just to be safe
perhaps it is b/c it's an "Asset" blueprint?
maiden wadi
@livid pebble Were you trying to make a Blueprint class a child of that CPP class and then access the CPP function from the BP class? Not sure I was following that conversation correctly.
worthy frost
he is, tho he is also passing non const ref to that function so even if he finds the function those will be Out Pins ๐
maiden wadi
First note is that your UCLASS isn't Blueprintable
maiden wadi
Ah. Will keep that in mind. Had that issue with an ActorComponent.
worthy frost
components are not Blueprintable by default
@livid pebble also void setMapSize(int32& rows, int32& cols); will produce two output pins in the editor
and you should not pass primitives by reference
void setMapSize(int32 rows, int32 cols); is all you should do
livid pebble
I would learn and fix up issues once I could play with the function.
I mean I'm sure your right but I can't experience the errors without getting there
livid pebble
yesterday I had it working by starting with a C++ class and then adding a blueprint. However, UE4 would crash every time I hit "Save" in the Blueprint
@worthy frost correct
worthy frost
are you compiling with editor open?
livid pebble
yes
worthy frost
if so, close the editor and reload, and don't compile with editor open.
maiden wadi
Splat.
livid pebble
I'm sorry, just to be clear.. do you mean the VS2019 editor or the UE4 editor?
maiden wadi
UE4
livid pebble
is this a known thing or something?
like I said, I started last night so all new to me
maiden wadi
Close UE4 and F7 in VS, then reopen your UE4 project.
It's just the way that the editor handles stuff. Hotreloading doesn't work very well for CPP/BP developing. It'll mess your blueprints up more often then not.
livid pebble
heh
maiden wadi
If you turn on LiveCoding, it'll stop F7 from working when you have UE4 open and let you compile functions you've already declared. If you want to declare new functions or change .h files or are not using LiveCoding, generally always close UE4 before compiling in VS
If you don't close your other windows and just close UE4, it'll ask if you want to reopen them when you restart the project, makes it a little easier.
spark skiff
Quick question, Is it possible to have my point lights inside actor blueprint to affect other object in the scene?
maiden wadi
Don't they by default? I've put pointlights inside of actors and placed the actor and the light affects everything around them.
spark skiff
@maiden wadi Mine doesn't work like that. I think it should work like you described but somehow it didn't in my case.
maiden wadi
If you make a new actor, add a pointlight and a static mesh, and place that in the world, it should light up everything around it included the static mesh. But in your case it's only lighting up the static mesh, or?
spark skiff
It didn't light anything outside the BP.
But seems to be an error with the editor. Restart the editor works. Didn't know what happen though. I'm using 4.25.1
@maiden wadi Thank you for the help. ๐
livid pebble
So I made a new class and got the blueprint to have my function in it. But as soon as I clean save I crash
livid pebble
I assume you guys realize how frustrating errors like that are for people just getting started and not knowing the secret rules...
I'm going to start this completely from scratch... but I have a nasty feeling it will crash within the first few steps
I'll document them if you guys don't mind...
trail rampart
those are not the secret rules
livid pebble
2) Create a new C++ Actor Class called "MyActor" in UE4 - VS2019 code is auto-generated with base code.
3) Drag MyActor content into the Perspective Viewport
4) Click on "Blueprint/Add Script" button associated with the "MyActor" instance
here is where I think it breaks
trail rampart
I would not name project as Test
livid pebble
what should I name it?
trail rampart
make it "TestProject" at least
livid pebble
okay, fine
if that makes a difference though... not sure if my monitor will survive
trail rampart
livid pebble
by the way, I appreciate all of your help.
so.. I'll see what happens, but my worry is that if I hit "Save" in the "MyActor1_Blueprint" UE4 will crash
note, I haven't even created any variables or functions in the MyActor .cpp/.h exposed to blueprint
livid pebble
I can, but I figured here as the crash happens when I'm in Blueprint editing mode, not in CPP code
and yes, as soon as I hit "Save" UE4 crashed
maiden wadi
@weak cosmos I might be mistaken but it looks like you're overwriting your savegame object each time you change one of those indexes. You're creating a new save game, setting that one thing and then saving it in that slot. So when you load it up it should only have one thing changed?
mellow stump
Yeah, id do a DoesSaveExist or what ever the node is called. If exist, just save info to it
maiden wadi
@weak cosmos Does the SaveGame file exist in your project?
weak cosmos
Yes, I have a blueprint instace of it
Gonna setup new "does save game exist" function now
maiden wadi
No, I mean after you've started up your game and tried to change something, does it actually write the savegame to disk?
weak cosmos
Yes, does save game exist returns "true" on beginplay
But variables doesnt return true values
For example, face index is set to "2", but it always starts with "0" when I press play ("0" is default value)
So basically its not saving
mellow stump
So if SaveGameExist, dont CreateSaveGame
onyx swan

You should be able to Get/Set the camera boom rotation

onyx swan
its been a struggle as long as 'use pawn' is enabled
which i need for controls
unless i did some major refactoring i guess
maiden wadi
When X is pressed the first time, It'll print No Saved Game. Press Z once and then X it'll print 16, press Z again then X and it'll print 32. But it'll just keep printing 32 until you delete the save file in your project files under ProjectFiles/Saved/SavedGames
If you're consistently getting back the default value of that savegame, I'd make sure that the save file exists. If it does, delete it and try recreating it.
weak cosmos
Its not returning the default value, its just not changing the mesh
I solved the savegame part
Thanks for helping

Button of a tabbar controlling a widget switcher with 4 tabs (index 0-3); trying to get fade in/out animations right, this setup works as I know which widget I want to pull up to make it fade in, but how can I elegantly get rid of the widget that corresponds to the currently active index?

pearl rose
@median jacinth turning what? an actor or a character base class? regular actor you could simply offset rotation or set the rotation to the desire one by adding +90 to your Z value. If it's your character then you'll have to set the control rotation
@atomic light I believe widget switcher doesn't have animation support, it will always pop-in and out. You need to do your own container to have your fade-in and out
@fervent crag this is an occasion to add some code after your input axis. If the value is above or under zero run that logic -> set your camera rotation using Finterp and just set some minimum/maximum value considering your input axis are always in between -1 and 1
atomic light
I had their animations in their own widget BPs but the problem there was they'd only animate upon the first click/event construct and I'd have to remove that widget when clicking on another one, still requiring me to know which one is currently active

How can I change a parameter value of a decal in blueprints? I want my decals to have a random parameter so every decal looks different. Did some googling and apparently the only way to change decal parameters is with a MPC? But that means I have to make infinite MPC's for every decal spawned? That can't be right lol What am I missing here? There is no way that is not possible in such a powerful engine ๐
maiden wadi
@untold fossil You have a material that you're using in a Decal Component and you want to change a parameter in the material?
untold fossil
yup exactly
I have a random rotation parameter inside my material (scalar), upon beginplay of my blueprint I want to feed a random float into said scalar parameter. I can't use a normal component rotation as the rotation only rotates a mask, the inner parts of the material need to stay horizontal at all times.
I would be mind blown if there is no way to do this.. Been using the engine for over 5 years now and pretty much never came across anything that isn't possible one way or another. ๐ค
maiden wadi
@untold fossil Made a quick test with a simple material and a decal component. Seems to work fine this way, can alter the color, probably make a random one.
untold fossil
I did exactly the same thing and with me it shows an invalid material
it shows the default Unreal material

You can also put it in the construction script

what's is the best way to do a linetrace interaction text?
nocturne remnant
probably AI unless you wanted to get into some classic MMO-style multi-boxing setup where your player controller actually sends commands to all of the pawns
trim matrix
Oof
In this I'm trying to get the absolute of each number to see if it's the same, and use a different float value if it is the same... How do I do that through execution pins? (So true sends one value and false sends another one)
Without duplicating the entire script
earnest tangle
I think you could probably use a select node
it would allow you to pick one of two values based on the bool
I'm not a 100% sure if that graph will work tbh since you're wiring up parameters from two separate events ๐ค
nocturne remnant
Yeah, you want to use a select. Input axes constantly output values though, so it would work.
trim matrix
Ah alright thanks, I'll try it :)
nocturne remnant
Select is one of your best friends
trim matrix
Yeah I didnt even know it existed lol, good to know :p
nocturne remnant
You can use it with ints and enumerators too.
when you've programmed before, you right click, type "if" and it brings up branch... so you think that's how you do basic logic for it. It was a while before I found out about select by accident.

Does anyone know what this node is supposed to mean? I found it off of some online blueprint, though UE4 doesn't seem to recognize it when I copy it in.

@nocturne remnant the primitive solutions never fail me
just made every button take this sequence first and only then it plays its own tabs enter animation
oblique ruin
I'm a little confused about the camera functionality in Unreal. Is there a way to bind the camera to no particular controller (or all players)?
nocturne remnant
Couldn't you just set the active tab to a variable and pull the animation from it and run it into the play animation instead of branching?
presumably, you'll need AI at some point, so it's probably not the worst thing to know.
otherwise, I would foresee you running into collision issues if anything else in the world moves
@oblique ruin are you talking about just having a single camera... somewhere?
atomic light
just remove the camera from your player and plop one into the world, thats simply a static camera as an example
oblique ruin
Ive been running into the issue where if player one is deleted the camera stops functioning
atomic light
dont know what preset or whatever you started with, but im guessing most likely its your player that has a camera attached to it, so if its gone, so is the main camera
oblique ruin
I didnt create the project but I believe the preset was the 3d person.
atomic light
yeah, the player blueprint has a camera attached to the player model by default
so if you open the player blueprint and remove the camera there, put a camera in the level and play it 'should' be a static camera
from then on experiment as you want
untold anchor
Not sure if this is the correct area, but i'm having trouble with trying to get my wall running, It works (mostly) except the capsule is rotating and thus rotating the traces as well, which when changing directions a bit too much causes the traces to no longer hit with the surface you're running on, and then it pops you off cuz well no trace hits. The movement seems to be going based off the character direction for which direction wasd moves you in except somehow also the since the character orients towards the hyptothetical forward direction of the camera (though even that isn't entirely true either). I've gotten a bit lost in my maths and I'm not sure how to prevent the capsule rotation (which seems to be caused by the camera strictingly changing the character direction, however if i disable that, the capsule no longer rotates, but then the 2nd problem happens where the running direction is very unintuitive, and if you change directions too much you still pop off). I'm willing to share w/e information is needed, but i've spent a week trying to resolve this and having barely any luck making progress at this point. Any help is greatly appreciated.

it's a challenge for sure, i mean, i could easily do the typical flying, force and box ditection method, however, it's a 3rd person game
and i need to be able to run on surfaces practically infinitely (until stamina runs out, you jump off, or hit a ledge that you can't continue to walk along)
sooo, a bit more of a challenge, i've watched every youtube video i could find on the subject

does his method involve impulse?

I want to spawn a random actor blueprint from all of that class
Let's say I have room a, b and c
nocturne remnant
First, I want to say that I'm happy your wiring doesn't look like complete shit, though the render seems to not be doing it many favors in a few spots. Have you tried using a capsule trace instead of just a line trace?
floral quail
My biggest issue is I don't know how to store the references to these blueprints
I'm coming from unity and the way of thinking is a little different
untold anchor
thank you, i'm really new, have only been using EU4 for like 2 weeks now X_X I have tried the sphere and capsule trace, and i think the reason he used a line trace was that the only information he needed was did it hit, what was the normal of the surface it hit, and the location of the hit
unless i'm mistaken, no other trace is really needed since you can get the same info from a single line trace
floral quail
So how would I create an array (or automatically generate) of a certain class
untold anchor
you can create an object array variable
put your objects in that array, and then call on them with an int or something
if i'm not mistaken
if you're wanting random, randomly out put an int from a range of 0 to whatever amount of objects you have in the array minus 1
and then use that to call the object out of the array
untold anchor
yea, blueprints are fun, i'm liking them
nocturne remnant
The reason I asked about that was because if the line misses because of the direction changing quickly, you'd have a trace that's using a larger surface area.
untold anchor
i see, hmmm, let me show you what i mean, as it's hard to describe
oblique ruin
@atomic light By static I'm assuming you're not referring to this correct?
atomic light
thats a property most things have youd have to wait for an answer from someone more experienced
like, as long as you plop a camera from the actors list into the world it should be "static" per se, as it wont take any input from you because your player controller consumes the input
oblique ruin
Ah I see.
untold anchor
Casting @bitter star if i'm not mistaken
also parent child
when you create a blueprint it asks what you want to make it a child of
atomic light
@oblique ruin not sure but that might just be like a general override switch on whether that actors coordinates can be changed from either interaction or blueprints, etc
untold anchor
though i'm not sure how to change that after creation though

What's the best way to get weighted random numbers in blueprints? For instance, instead of getting a number between 1 and 100, I want to still be able to get every number between 1 and 100, but I want to get between 30 and 70 the vast majority of the time. Like a bell curve for random numbers
untold anchor
https://streamable.com/djhi3g @nocturne remnant
mellow stump
C_D Tags and Interfaces work well, then GetAllActorsWithTag and /or GetAllActorsWithInterface
If theres just one to worry about, its easy, if theres multiple in the level you have to work off which one you hit with a line trace or which one did you overlap, ect
oblique ruin
@atomic light Hmm I do notice in my character bp (subclass of Character) that there is a camera section
ns if its there by default though
floral quail
@untold anchor I made an array of actors, but it only shows ones in scene?
Guess the blueprints in the content browser are blueprints
Not actors
untold anchor
depends how many you want to use, you can use a loop for that
if you want 4, you can loop it 4 times i think
well 3 times
i think lol
atomic light
@oblique ruin on the top left side you should see all the components of your blueprint, like the mesh and the camera
oblique ruin
I do have A camera attached but it's separate from that.
untold anchor
@fathom portal I think the easiest way to do weighted random is to create a larger value range, and then choose subranges to do certain things, like 1-1000 range, and if you want something with a 1% chance, then make it use a 10 number range, and if you want a 10% chance, use a 100 number range
oblique ruin
Or at least it should be
nocturne remnant
@fathom portal you could make a curve table... or you could make a float curve that has the distribution you want and then grab the value for a random time on the curve
fathom portal
Curve table! I knew there was something I was missing
oblique ruin
@atomic light yeah the initial camera that came with the preset was deleted.
fathom portal
Thanks @untold anchor and @nocturne remnant lemme impliment that
untold anchor
all credit goes to justin, i was just taking a shot in the dark lol
atomic light
So now if you put a camera into your level and press play it should switch to that instead
and not follow your player since its not attached
fathom portal
Hey man, progress is progress, teamwork
nocturne remnant
curve table is what you'd want to do if you know the exact distribution that you want... if you just want something that looks like a normalized distribution, drawing a curve in the curve editor is probably easier
floral quail
No thoughts on instantiating from content browser?
untold anchor
also, justin, in my video, i'm locking and unlocking the camera to be seperate than the player's movement with a button, when the capsule rotates, it's using "use controller rotation yaw" and when i'm able to move the camera with it rotating the capsule i've temporarily disabled that
i get one problem when i've got it enabled and a different problem when i have it disabled
oblique ruin
I think the issue may be more that the camera is bound to the player controller rather than the actor itself.
Cause the level I'm in has no active player controller.
fathom portal
@nocturne remnant basically the use case is for procedural generation, each island gets a base tempature/humidity, then they get a float value which is the maximum temp/humidity variance that the individual places on the island can have. So a naturally hot island will still remain hot, but can get slightly cooler/hotter throughout the island

that are generated? or are placed there always?
floral quail
Let's say I wanted to spawn a projectile? Does it need to be placed?
And then spawned from that

if placed there always, justs include it in your level and place it, if it's generated, you'll likely need to use an array

just the object? what about the object's location? any variables of that object also need to be random?

depends what you have the room as
floral quail
Yeah, but wouldn't you pick actor usually?

If you create a blueprint and pick actor
I could still only see what was in the scene

for spawning stuff, you want the class

@nocturne remnant which first collision are you reffering too? i have them color coded on the traces, so you can refer to the color if you'd like

@solemn zephyr You might just be best just making your own solution. There's a ton of (good and bad) procedural generation solutions, but if you already have the pieces made, adding sockets to connect them is likely the way you want to go

Cause I feel like that's probably a more appropriate channel
atomic light
just ask here i think its fitting enough
nocturne remnant
@fathom portal a curve table is probably what you want then since they're just spreadsheets. At least assuming that it doesn't lose its shit on a non-increasing data point.

I think that's the thing? lol
don't think it'll include the character geo, anim, etc etc etc, but it should have the blue print i think

@fathom portal the problem is I have no idea how to make something that puts those rooms together or even places any kind of geometry
untold anchor
have you created a blueprint with that room in it?
nocturne remnant
@untold anchor I was talking about right at the beginning. Orange hit, orange trace, cyan hit, cyan trace facing totally away from the wall
fathom portal
@solemn zephyr Check out sockets, they're basically points in space that you can attach other things to. So like legos, you can put it together, or have it put itself together. Are all the pieces the same size?
solemn zephyr
@fathom portal the rooms are already designed to fit into each other, I'll do some research on what sockets are and how they work
proud hull
fathom portal
Sockets are great, honestly. For instance, this is one of the building systems from the marketplace. It has foundations, then sockets are aligned to them to where floors can be:
proud hull
@oblique ruin is the camera attached to the player character being removed? If so, you can detach the camera itself before removing the player character. Also try unposessing if you wish the player controller to remain active after the character is removed.
fathom portal
@solemn zephyr This system isn't procedural, but the process would be the same. You'd check the sockets, see which aren't being used, then attach a wall (or in your case a room) to one of the sockets. Then mark that as "used". Then add the new rooms' sockets to the list of available sockets, rinse and repeat until you get as large a building as you want
solemn zephyr
I'll work on that, thank you
untold anchor
ah, yes, so while he's running (though this behavior will change for when the initial ray cast happens) it's looking for a hit, if it hits, it then checks if that surface is greater than (roughly) 45 degrees, if it is, then it sends a second cast out x amount of units higher in z, if that also hits, it saves both the normal and the hit location of both of those traces, and then does some maths to get the rotation and such of the new location in comparison to your current rotation. Then once you're on the wall, it's then doing a cast in your "new" forward / Down direction, and also in your directly down direction. as long as your down direction has a hit, you stay wall mounted, if it does not, you get put into a falling state and gravity is reapplied. While you're mounted, if the Forward Down cast, hits and it sees that the surface is greater than like 45 degrees (roughl) then it'll do the calculation it did before and then reposition and change your rotation to match the new surface. Also always casting a trace directly forward as well while mounted to do some maths for that surface to surface transition as well.
the capsule is rotating asif i were on the ground, so when i change my yaw with the camera, it's rotating the capsule not as if it's new yaw is relative, but more so world space yaw, so then the capsule is behaving like a roll (relaitively speaking) when it should be acting like a yaw (relaitively speaking)
so when it "rolls" the the downward trace eventually gets to an angle that it pops off, however, if i can figure out how to stop the damn capsule for even rolling like that, i think it could solve the problem

directly into a corner? or just running straight at a wall?
also, what all was included in that file i sent?
nocturne remnant
On a wall toward another wall. I just threw it in the third person template and hooked up new control inputs
untold anchor
i see, hmm, for me, when i'm running horizontally on a wall, and hit another wall it transfers pretty well
nocturne remnant
It's just the blueprint and the components
untold anchor
if i run downwards towards the ground it mostly kinda works, gets a bit wonky, but i'm gonna add a hitbox on the ground near walls, that once you collide with it, it forces you out of wall run
running right at a wall though, will immediately pop you off
so you have to hit it a slight angle
and when you're running on a vertical surface, you almost have to stop moving, direct your camera in the direction you want to run, and then run, or else the controls get weird
and not sure if you hooked up the "left alt" to change camera modes
once you get on the wall, and if you hit left alt to change the camera mode, the controls get weird, unless you're running upside down on the roof, then they behave decently
currently uploading the whole project as nothing in it i'm particularly trying to keep to myself, as it's just locomotion, and since there are so few available wall running things out there, once i get it solved correctly, i'll just give it away for free
nocturne remnant
untold anchor
ah, yes, that wonkiness when you're on the ground sideways, i don't know exactly what's causing that, hence why i'll just create a hitbox or something for the ground that forces you out of wall run state and back into walking
which will orietate you the correct way back to the ground
as for the jankiness that's happening in the corner when you're wall running, i don't have that particular issue, but you might be doing something that i'm not movement behavior wise
nocturne remnant
well, I can break anything
untold anchor
lol, that's a good quality in this line of work
in that video, are you in the normal camera mode? or are you in the "left alt" button camera mode?
nocturne remnant
just the default one

nocturne remnant
Yeah, I had to change that.
Something that didn't occur to me at first... why is it tracing up on the wall instead of ahead of the direction you're moving?
untold anchor
it's basing it on the "upward" vector of the wall
i'm assumin you're reffering to the blue downwrad diagnoal trace?
i've been confused why it doesn't do it downard forward of your movement direction, but that's the way the guy had it set up for his spiderman thing too
and it works well for him, but logically i feel like it should go relative to your character
also, are you have the rotating capsule thing i was having?
untold anchor
try to left alt camera mode once you get on the wall
it stops that
but, movement becomes a bit unintuitive along with that
kinda stops it
more or less, the behavior changes completely

How would you write an equation that generates an outcome from a given percent chance variable

twilit heath
it takes a float (chance) and returns a boolean
gray kite
Thats awesome I didnt know that existed
I had a whole equation written out lmoa
Been looking at this too long
teal burrow
Also on the enums, they're saved like in C++, under the hood they're just a Byte where you can get a value with a name
When you modify an enum, it keeps that value no matter the name
twilit heath
with c++ if you assign values manually, you can leave yourself some room for inserting an enum member
teal burrow
Generally it doesn't hurt to futureproof yourself with as many members as possible
twilit heath
UENUM(BlueprintType)
enum class EMyEnum : uint8
{
First = 0,
Second = 4,
Third = 8
};
then you could insert something between First and Second with value 1-3 without breaking blueprints
but either way, its pretty shit ๐ฆ

I just sorted my enum values after implementing something and all references in my behavior tree are outright wrong now. Which is a big issue, since I build a state machine and the enum represents the states ๐ฌ
About C++ enums etc I have no issues as a long time programmer but I didn't expect this to happen while working with blueprints only.
(Obligatory footnote: Rust > C++, sadly UE transition is a huge effort)
twilit heath
@vernal wind i strongly recommend you switch to using GameplayTags instead
they are a bit of a pain in the arse to input into the project the first time
but later they become far more flexible, and also they have hierarchical structure
Attacking.Melee and Attacking.Range tags would both pass a match for Attacking tag
simplifies things in a lot of cases
and if you add a IGameplayTagAssetInterface to your object, you can check for them without knowing what class the object is
vernal wind
Just read the docs. Seems a reasonable better alternative but how would I import them into the Blackboard so I can use them for behavior tree decorator nodes?
twilit heath
decorator nodes are easy, should even have an engine decorator that checks the tag
they Attacking.Melee tag also corresponds to Attacking.Melee FName
it has a GetTagName function that returns that exact name, infact
and you can pull a tag by name from TagManager
they are a bit easier to work from BP then from c++ because of editor customizations for them
in BP dropdown opens hierarchy and you just put a checkbox on the tag you want
in c++ it would be FGameplayTag::RequestGameplayTag(TEXT("Attacking.Melee"))
vernal wind
Ah I found it. I must replace the decorators with others but that seems to do the trick. Great! Thanks you very much. Guess I will refactor enums out this night :P
twilit heath
you let CMC replicate movement on its own
as for the rest... it really depends what the action is
what type of game it is
and what your structure is
@bitter star if you haven't already, i strongly suggest you give this a read http://cedric-neukirchen.net/2017/02/14/multiplayer-network-compendium/
@vernal wind they are very useful, i use structs with GameplayTag + float to handle all my stats in a generic way Kills, DamageDealth, MissionsCompleted... whatever i need
you can also use tags GetTagName to access DataTable rows
vernal wind
I will bow in awe before Cedric's guide. It is the best documentation I ever found in regard to network replication. Without it I probably would have gone insane last year.

worthy frost
you clone the pawn, and you need the clone to respond stuff
quite tricky tbh
not easy to do in BP for sure.
@spiral bison Tick is overkill
for starters
not sure why you want to interp the XP
if its for UI, then your UI should handle that
spiral bison
So that it doesn't throw a decimal into my HUD
worthy frost
you don't need to do that tho
vernal wind
@spiral bison Seems like your problem is the communication between your character(?) containing the data and the UI/HUD displaying the information.
You will either need to manually inform the UI about changes made to the data or bind the displayed UI value to your data variable, so it updates itself.
Either way you most probably won't need to do this on every tick, since I assume you will only get XP for some events like e.g. killing a mob. So you may want to work with triggers/events which notify the parts that need to update instead of constantly checking the state like 60 times per second.
Since you are a beginner I would suggest to view some tutorial e.g. how to display a HP value which should contain all the parts you need.

@hoary gazelle look at Switching Between Fixed Cameras. https://docs.unrealengine.com/en-US/Gameplay/HowTo/UsingCameras/SwitchingCameras/index.html You can use SetViewTargetWithBlend

Ive tried this, but I cant call for the cameraactor from the playercharacter

@hoary gazelle you mentioned in your question you want to 'have my character switch to a different stationary camera', that is how you do it, no need to call any camera on any other character. ๐

I have a bunch of similar-looking menus. Upgraded one of them, and now I want to add those upgrades to all of them. There isn't any fast way to copy a dozen functions into 7 other widgets is there?
thorn ermine
@hoary gazelle you just need to get a reference of the camera actor in the scene, you can do that by tagging it, and getting it by tag anywhere in any blueprint. no possession required . if you want to blend to a camera attached to another player ( * i.e not a stationary camera ) you can get a hold of that character using get player character with an index, or by casting a trace | sweep, or by tagging it, and then in the blueprint where you want to initiate the blend to, you can drag out the 'followcamera' or what ever the camera variable is called on that blueprint as part of the blend input. we use it ( GetViewTargetWithBlend ) all the time and it works like a charm.

@modern cove Yes and no. If you open up the blueprint function, you can copy all the 'innards' by selecting it, create the function in menu 2, and paste the code in there, you would have to ensure that your variables are named the same ( blueprint copy | paste is actually just readable text in the clipboard ) BUT, and there is a big but... it would be better to try and use some form of class hierarchy where you can extend from, and implement this function as a once off, and have all child blueprints inherit from this base class, and then all child blueprints|userwidgets can simply call it, as next time you want to change your function, you have to replicate it 7 times again, whereas with inheritance, you only have to change it once.

How does one allow a character to run up 360 degree loops with the CharacterMovement component? The issue I'm having with this particular component is that is that the walkable floor angle can only be set to a maximum of 90 degrees. So when the character runs up the side of the pipe, it stops halfway. I've looked into bypassing this issue, and while people seem to have accomplished this with the CharacterMovement component before, I can't find a proper source on how to do so myself.
This is the sort of loop I'm talking about. Think like how Sonic is able to gain enough momentum in order to run a full 360 degree loops. I want my character to run around the inside of this pipe farther than 90 degrees.

I messed around with some C++ coding early in my little project. I found it was so far removed from what I worked on in college, and so temperamental with Game Instances that I said "#& it, I'll just make one with Blueprints." Since then I've made some remarkable menus and got an Inventory system up and running where I can use, trade, and trash items. I modified the inventory system to make a Spell casting menu too.
Next plan is to use what I learned from Items and Spells to establish a system for Arms and Equipment

@novel gull This also will tie in with adapting gravity to be non constant, but vector based. currently this is not possible without modifying engine code AFAIK

you can do it with traces, and changing the character's movement and rotation

still trying to figure out how to prevent my character's "roll" relative to them, not world space, to stop changing when i move my camera

Oh thank you mippi. Also thank you for embedding an actual video tutorial video for this sort of thing as well. It's hard to find stuff relating to "loops" without getting results about a very different kind of loop lol
untold anchor
i'm like 99% of the way there
just gotta prevent the roll on the capsule from happening when you're on a vertical surface (as being upside down on the ceiling is not a problem) and then do some logic on the controls to tweek a bit depending the verticality of the surface
and boom, done
i mean technically, this will currently work with a loopty loop

@trim matrix so how do I make the character run in that direction only?
maiden wadi
@median jacinth Might be worth showing how you're making the character move in the first place.
maiden wadi
Actor Forward Vector? Specific World direction?
median jacinth
I'm sorry but I'm not getting that , I'm super new to unreal !๐ @maiden wadi
maiden wadi
What do your A and D keys do in the character blueprint?
median jacinth
I just change the Actor with camera by A/D keys when a corner comes , I wanna do the same with button
maiden wadi
I mean if your character is moving forward based on it's own forward vector, then yes, simply turning it 90 degrees once on button press would make it endlessly run in that new direction.
vernal wind
@elder plank you could use a collision event like begin overlap to get the actor/pawn/character in contact with water/fire/acid and from that the player controller owning it. But beware that in networked multiplayer you have to manage it through player states or the server since you can't access other player's controller for security reasons
median jacinth
When I hit a button, the character Just looks At the direction and then continues to move straight
:(
maiden wadi
That's why I was asking how you're making the character move in the first place. If it's based on a set world vector, turning the character won't change it's movement direction. If it's based on actor forward vector, turning the character would change it's movement direction.
Kind of need to know how you're making the character move forward in the first place before the turning can help at all.
median jacinth
@maiden wadi I'm sorry If I'm not getting what you're Trying to say, cuz as I've told I'm a newbie
:(
I'll just Check soon how my character is moving forward and I'll surely let u know !!!
maiden wadi
Do you hold down W or something to make the character move or does it do it on it's own?
median jacinth
On its own, I think I had an event tick on , so it moves endlessly
maiden wadi
Check Tick then. How are you actually moving the character? Most likely it's a Set Location or an AddMovementInput
median jacinth
My character moves Endlessly on its own, and I just Make it Go left Right By Joystick or hitting A/D

Is there a better way to accomplish my goal? I want to have an interactive visualization of an axial MRI NIFTI. Since I couldn't find any plugins which had image volume viewing functionality. What I did was create a sprite sheet out of a sequence of axial images and made blueprints to make the animation progress forward and backwards frame by frame on a key stroke while having the plane move up and down Z with the same stroke. It definitely works, but I wonder if there is a better way.

Seems like a fairly reasonable approach to me at least :)

gloomy grove
speaking of which... what is an rpc?
trim matrix
remote procedure call
maiden wadi
@gloomy grove For stuff like a door, usually you'd just create an input event in the character that calls an RPC event in the same character. What this does is tells the client's version of the actor to tell the server version of the actor what to do. Then the server version of the actor would tell the door to open, usually by setting a replicated variable and on repnotify play the door open event so that it's always correct, but if you don't care that much you can always just use a multicast on the server version of the door.

Hi guys, could someone tell me how to track the distance from the ground?

@ember token actor location line trace - (10000) max distance to ground then break out hit result and get out hit distance
or actor location - hit location vector length
ember token
mh.. wait
I think I get it, I made something like this
with the vector lenght I created the variable
maiden wadi
@gloomy grove Just a sec, I can give a bit of an example of a simple blueprint RPC that might help with the understanding a bit.
ember token
is it right?
sly spade
yup
the 10000 is the distance to the end of the trace
i think you can also use the pin above which just is distance
see what works best
ember token
ohh
I'll try both! Thanks a lot ๐
so basically, this script should create an imaginary line from under my character that goes to the lowest part of the map?
sly spade
yup, you might also want to make a collision channel that only looks for the landscape etc
encase it will just return the distance to what every the line hits with collision
ember token
ohhh, It makes sense
so this line basically takes as hitpoint the part of the line that touches the first surface under my char?
maiden wadi
@gloomy grove This is a simple one for crouching based on a repnotify variable. What this does is on client keypress, calls an RPC with a boolean input. If pressed this makes a call from the client's version of the character to the server version of the character and the server version sets the variable. Since the variable is repnotify, the server will tell all clients to change the variable and then those clients will run the function associated with it changing.

@gloomy grove All of that is in the character.
@gloomy grove Try very hard to avoid doing anything in the level blueprint. It's not a very good place to be doing anything related to game functions. It's more of a level designer's tool for very map specific things. Try to keep functions related to objects in those objects.

@tight venture You can lower the grid sizes from normal to 1 pixel which would effectively disable them, but that will disable grid snaps for everything. Not sure there's a comment specific setting for that.

Been out for a while, thought I'd be able to get back by now but apparently not
I was looking over the blueprint, one of your comments seafood "ran on server" but you said it's all in the player
Is there an exception or am I missing something
maiden wadi
@gloomy grove Unreal's networking is kind of like a room of mirrors. One is the real actor(which is the one that exists on the server) but there is also an actor for each client. Say you have three players and one of them is the server machine. Initially you think three player characters? There's actually nine. There's a character for each player on the server, a character for each player on the first client and a character for each player on the second client. So three characters on each machine, nine characters in total. Sticking with the crouching methodology, what happens is that if client 1 presses the crouch button, that only ever plays on that one character. The client's version of the client's character. Which is why you need the RPC event which is the CustomRPCEvent in that picture above. This is a message from the client version of the client's character to the client's character on the server that tells the server version of that character to set that boolean variable.

@dapper siren Sounds like you need to get a reference to the level sequencer and tell it to stop playing. It might be easier just to make the bird an actor on it's own that has it's own sequence reference or a timeline/tick function running to move it that you can stop when it's grabbed.

tacit shard
hey
im using set timer by function name to delay something but it can be called again before the time has passed so cancels the previous calls
whats the best way around this?
maiden wadi
@tacit shard There are a couple of different ways you could handle it. Simplest is probably just to make a timer handle and ask if the timer handle is active before calling the SetTimer
tacit shard
what if it is active? i still need to run the function after x amount of time
i basically need to queue up some timed functions
maiden wadi
Oh, you're wanting to call a set timer by function based on the number of times a button is pressed?
tacit shard
no, im performing a predict projectile trace that has penetration, it can hit multiple actors during the trace, but im taking the simulation time of the hit and calling the hit function with a timer using that simulation time
so it can make multiple calls to the hit function in the same frame with different lengths of time
but only the last call works, since im assuming the previous ones are being cancelled as the next one is called
pseudo code while(simulationTime > 0) { predict projectile path with collision: if hit set timer by function "hit" with time of hit time. simulationTime -= hit time}
also ignoring the hit actor, so the trace can carry on on the next loop
maiden wadi
Initial thought says create an array with the time differences and call your set timer by function based on that. At the end of the called function, remove the first index of the array, then get the new first index and use it's time to call a new set timer by function name with the time from the array. Do until array length is zero.

I'm surprised that even works to that degree
When I was making a thing where you could roll a character it just went completely fucky because as far as I can tell, CharacterMovement always assumes the same roll orientation and just does not work correctly if it's not
untold anchor

i'm currently reuploading the imrpvoed version
that solves alot of the problems
however, there still is a few thigns i still haven't figure out how to fix yet
nocturne remnant
Yep. That's basically the issue. When you use the rotate to movement direction, it uses global vectors; you can't make it yaw based on the local Z
untold anchor
yea, so i'm thinking what i'll have to do
is basically set up a pitch, yaw and rotation
then depending on your current upvector
muddle with those values a bit to make it feel more natural
for the controller of course
some value checks, is greater or lower than, etc etc
earnest tangle
There is a directional gravity plugin (or something like that) on the marketplace which has a customized character movement component that works correctly with roll
Might be worth a look
untold anchor
yes, but it's not network replicated
and
it changes the gravity for all objects
not just that one player
at least from what i saw
earnest tangle
well you don't have to use the gravity aspect of it, you could probably just use the movement component since it works with roll
untold anchor
oooh
so if i'm vertical, it makes it so my controls feel more natural?
like a local orientation rather than world?

it should, I didn't try it with a 3rd person thing but it worked well in fps

i see, is it the one that was on the market place for free not too long ago?

yeah not sure if it's gonna fix your problem but I'd say it's worth a try at the very least :)
untold anchor
no, but could, so it's def worth a try ^_^
i didn't think abouot not using the gravity

You'd need to rotate interp to a target based on the movement direction considering the up vector, and also combine it with the rotations to get onto the wall
sly spade
@ember token tried it on tick, but video was construction script
shouldnt make any difference
nocturne remnant
Also needs the movement to change relative to the camera since basing it on the actor rotation doesn't make any sense once the perspective changes
untold anchor
yea, i don't know how to do that tbh XD
i've thought about how to make that math work, but i don't know enough yet to pull it off
however, the main problems i've having now is the whole -90 to +90 flipping when the camera gets right over the had of the player
head*
it happens in one tick, but that one tick is enough to launch me off the wall
cuz the traces technically invert for a brief moment
you don't see it as a frame of animation though
just mathmatically
cuz if has to cross the 0 point in order to reach that
and 0 makes it think it's off the wall
-90 is on the wall, and 90 is on the wall, but 0 is not, and i don't have a clue how to prevent that X_X

welcome to gimbal lock

i was thinking that was the problem X_X

I'm sorry for the nooby question, but all the tutorials I've seen for this problem give solutions that don't apply for this problem. To give a high overview, It's a billiards game that needs to differentiate between solids / stripes for scoring. I want to update a variable in one (Score_HUD) class using an overlap event that happens in another. (Bumper) class.
Everything before the set nodes works as intended, but when it comes time to stop reading / modifying variables from the "ball" class and update the score variables in the HUD class it starts to break down.
Is it not possible to cast to multiple classes in the same execution? It seems I can only get the Score_HUD casts to fail, or compile but do nothing when given a "None" Type Score_HUD object that I'm trying to use to target it.

@rancid anvil Im not sure the issue it seems like this would work perfectly fine. Everything before the set variables work? Have you tried just running print strings to test that? Is your hud reference valid or are you getting errors in the msg log?
Also on a side note
You dont need to cast to the hud
Since the varible type is already a Score_HUD its pointless to cast to it. It wont cause any errors if you do. But its not nessicary
nocturne remnant
it should throw a warning about an unnecessary cast
rancid anvil
I tested before the set by flying around and watching the noodles light up
hud reference not valid sounds right

oh no it should look like that
If it was invalid, there would be errors apperaing in your message log when the code runs in game

Yep exactly
So the issue seems to be that you have never set the variable for score HUD
Its a reference type variable so you need to specifly Set it to tell the engine Exactly which score hud it is
