blueprint

[midnight ravine]

quick question:
I made an Event Dispatcher inside my Level Blueprint and bound it to an Event as you should. Next I wanted to call that Event Dispatcher from within another Blueprint but it does not show up at all?

[dawn gazelle]

I don't believe you're able to reference the level blueprint from other blueprints. Instead, consider having the event dispatcher on game state. The level blueprint should be able to get reference to it to be able to call the dispatcher, and other objects can bind the event dispatcher on the game state without issue.

[midnight ravine]

@dawn gazelle I need to modify state on an existing actor inside my level. Should I rather just store it as a variable and not interact with the level blueprint at all? Otherwise I feel like I'm calling event dispatchers just to call event dispatchers

[dawn gazelle]

Event dispatchers are good if you need multiple things to respond to an event - so you can have multiple blueprints bind to the dispatcher and then do their thing when the dispatcher is called. Did you place the actor manually in the level and need to change it?

[midnight ravine]

well I need an actor to change state based on a widget

basically what I have is a timer in the level. The player would enter numbers inside the widget, which in turn should activate the clock placed inside the map.

That's the coupling I'm working around

so my thinking went with "well I want the level blueprint to change the state on the clock. For that I want it to listen to an event dispatcher inside the widget since we can't reference the level blueprint and any actors living inside it directly.

but I totally forgot that I can save a reference of living objects inside GameState/GameMode or whatever I want and manipulate that instead since it's a pass-by-reference anyway

[leaden goblet]

Ok, i have a problem with widget component - 3d world widget.
I cant use it with mouse alone, i understand it should be like this or is it a bug? I need to use widget interaction component for that. But the problem is, even with source as a mouse, the trace is moving when the player is moving, and its not hitting where i have my mouse. Anyone had thsi problem?

What is the best solution for mouse interaction with widget components?

[crimson hornet]

?

[dawn gazelle]

What are the answers to the questions I had asked you? How are you setting that the player is dead? Are you sure you've properly set up your Is Dead BPI call correctly to return the actual state of the player?

[trim matrix]

@dawn gazelle hey man, I'm the guy that asked about the LineTrace function yesterday

Is something wrong here? because this simply registers "Aim Target Artillery" as 0,0,0

this is an example camera angle

[faint spire]

Hey so I am trying to make a scope in for a sniper rifle. I have it all set up to where when I press right click, the scope widget spawns and the character and sniper assets are hidden (so you cant see them in the scope) but when I aim in I can only move left/right but not up/down. Anybody know my issue? I'm sure its something small I'm looking over

[last abyss]

should warnings always be resolved? I mean I get a warning that an actor's component isn't set to moveable while its trying to move, this is a switch that will go down when a player overlaps a box collision and up when the player leaves. The problem was that disabling the box collision makes it move up again, so I decided to also set the mobility of the switch (which is a static mesh) to static. The only problem is that now I'm getting warnings saying that I should make the switch moveable if I want to move it. So the question that I got is: should I resolve the warning in this case or will it be fine to keep it in? I can resolve it I just wonder if it is absolutely necessary and what could be downsides of keeping a warnings in.

[dawn gazelle]

That view you have would probably be hitting the water or perhaps something else - but beyond that, you want constant updates so that line trace would need to be run on tick, I'm not sure it's executing at all if you're only getting 0,0,0.

You can also try turning on the "Draw Debug Type" and you can see the red line that it traces.

[trim matrix]

how are you setting your controls?

[trim matrix]

Thanks!

[trim matrix]

You should have actors listed as movable, at least that's what I did.

[faint spire]

What controls exactly? The mouse input?

[trim matrix]

Yes, did you separate the X and Y axis of mouse input?

[faint spire]

Yep mouse x and mouse y have their own inputs

[last abyss]

you would probably want to make sure something gets hit before setting aim target artillery ?

[trim matrix]

Well then it is probably a mistake somewhere in your blueprint code section for the movement

[trim matrix]

yeah I just solved it, I had to enable "Trace Complex Colission". Now it works

@dawn gazelle Thanks!

[faint spire]

Hmmm. Well my other guns work fine when ADS, but this one isn't working I think because I am hiding the character and sniper assets

[trim matrix]

Are you using the same blueprints for both hipfire and ADS?

[faint spire]

Yep! Sorry for a late reply

Heres the part of the code that is causing that problem

The two world location values are the world locations of the cameras i am interpolating

Never mind I'm dumb 🤦‍♂️

The camera I interpolated to wasn't using pawn control rotation

[trim matrix]

I see

[chrome sundial]

Can I force my Character for 2 seconds to move forward?

from Blueprint

[trim matrix]

I made a GameInstance type in C++ which holds the reference to a class which directly extends UObject, as shown:

protected:
    UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = "Properties|Inventory")
    UInventory* Inventory;

public:
    UInventory* GetInventory() const { return Inventory; }

The reference to Inventory is initialised like so in the GameInstance constructor:

    Inventory = NewObject<UInventory>();
    Inventory->RegisterGameInstance(this);

I now extend this C++ GameInstance class in Blueprints.

Now the conundrum is - I receive a valid reference to Inventory in C++ when using the pure C++ GameInstance class but the reference is completely invalid in both C++ and Blueprints when using the Blueprint derived GameInstance class. What should I do to get a valid reference to Inventory in Blueprints?

[chrome sundial]

I tried, but he seems to dont care, no matter what value. Maybe because I didnt called it over time?

[trim matrix]

How will I construct this instance?

@trim matrix if you're available atm I'll quickly test this and report back to you, sounds good?

Hello there, is there any reason as to why whenever I go into Orthographic mode in the Blueprint viewport it always chooses a lower LOD?

[chrome sundial]

thx got it :)!!

[trim matrix]

I would want it to look just like this

Okay the Editor itself completely crashed when restarted after build because it didn't like passing in a nullptr as the UClass* value

thing is it was working earlier when I used only C++

Oh I got that covered

Indeed, I'm not even sure

wanna take a look at some stubs from the class files?

oh cool, np mate

did, works with c++ GameInstance class, does not work with derived Blueprint GameInstance

aight

I did this:

private:
    UPROPERTY(EditDefaultsOnly)
    TSubclassOf<UInventory> InventoryClass = UInventory::StaticClass();

now it works

I had to put the Inventory.h file in the header, which I've learnt is not as good as forward declaring it

how so? doesn't the BP version call the constructor of the C++ version?

oh and there's no bp inventory

okay, now I'm changing this to the BP:

the bp checks I'd put in report this

and the C++ code reported a nullptr

darn it, it works with the C++ GI and not the BP GI

The change had no effect

let's try putting the init code in Init

@trim matrix I'm using this code to make the Inventory:

    Inventory = NewObject<UInventory>((UObject*)GetTransientPackage(), InventoryClass);

the inventory is a bp property because of UPROPERTY, right?

okay, I think I've solved it

okay so I solved it by putting all the code in the Init() method

Thanks for looking through it with me!

[feral stream]

Hello guys, I'm trying to figure out a way to better stop my character from moving off of a surface while climbing, so currently while climbing my character is in the flying state and to move I give him impulses of velocity, before giving him velocity impulses and while he is in the wall climbing state (meaning during the time he still has velocity) I do 2 line traces for his hands in the direction he is moving to to check if they will no longer overlap with a climbable wall - if they don't I stop his movement immediately. And here's my issue - this works fine on FPS=>60 but if the fps drops while he's moving towards an edge the character overshoots the stopping point or doesn't stop at all while he has velocity

[queen urchin]

Hi guys. Kinda strange question, but still

I have a streaming level for battles. And I need to clean it after battle (remove bodies, arrow, etc). Total reset to default state. How can I do it?

Wdym completely? Im unloading it for every player and for server too, still when Im loading it again it has all the trash. Also its not server travel, I have this level in persistent level

[maiden wadi]

Not as familiar with level loading, but it sounds like the stuff you're spawning isn't a part of that level, like the arrows/bodies and such. So it won't remove them when it's unloaded.

[queen urchin]

@maiden wadi Well, probably, but I dont know how can I spawn stuff "in level" properly. Never saw anything about it :/

Just dont want to make arrays of items and stuff like that cause IMHO its bad option

[feral stream]

I just want him to stop at the edge of a wall and not blow past it

[chrome locust]

how can this keep the player moving forward without pressing any input tf?

i know but when i press play it starts moving immediatly

without even pressing first?

dang

[chilly jetty]

Hey there

how do i ensure the AI always knows where I am?

I'm using the AI Perception

right that's true

[outer goblet]

Wonder if someone can help me. i got this spline which is the top one. The second one is the same spline with a second spline component set that each spline point 100 to the next so evenly distributed through the whole spline. i attached a ball to the first spline which moves from start to end and random speeds but i want to connect it to the second spline instead for a much smoother movement but i'm kinda baffled in how to do it.

https://i.gyazo.com/dfad5ddeddc50145ad3a852a6d6795a1.mp4

It actually looks ok but i have widget that tells the character where they are on the track based on the points in the second spline and need to have the ball connected aswell so the player can see the danger coming in the widget aswell.

i'm still new and i followed 2 youtube tuts and combined them to get this far. maybe point me in the direction for another one. lol

[left niche]

All my streamed levels disappear whenever I play a montage. The persistent one doesn't. whats up with this

[outer goblet]

are they set to always loaded?

[left niche]

No @outer goblet

I'm loading them from a Blueprint

[trim matrix]

Hello guys.I am making a battle royale prototype.Whenever i am falling from airplane "apply movement" function which we normally use for moving player is not working but once i reached the land "apply movement" function is working fine.Help me guys.Thank you

[outer goblet]

if you look on youtube, i think its devaddict, he uploaded a battle royale template which you can check and see how he did it. i think if you just search free battle royale template his will be at the top. for ue4 though.

[trim matrix]

Yeah but my bandwidth is very low.If you have that can you plz tell which node is used

I also tried add force but it is also not working

[outer goblet]

Um. well, right,,, ok, so like this templates bp is a bit complex so cant say its one node cos there's functions involved aswell. setting player movement, possessing pawn and yeah different functions for different movement types. Hold on.

That sort of might help in getting you closer. The jump action is using other functions which activate the movement settings among others but i think its more or less there where you getting stuck, switching between movement modes.

you cant move cos you falling.

[dull tree]

i attached camera to my mesh (head)

so when i play animations i get nice camera shake when walking/running

but if i check owner no see

its stops "shaking" camera

its attached still but dont shake

why is that or how can i get this nice shaking effect for my camera

[outer goblet]

But the camera is already invisible in game, no need to check owner no see.

[dull tree]

i mean mesh owner no see

[trim matrix]

Thank you so much.I will try them out thanks for helping memnoch

[outer goblet]

isnt that the same thing though. Does it have to be checked? is it really a need? What is the issue if it isnt checked i mean?

[dull tree]

its fps

i have normal mesh for 3rd person and 1st person hands

i need that 3rd mesh is invisible for camera

but still want this movement to be on camera

[outer goblet]

then its the mesh you want to check owner no see, but you have to run branches, is it fpview, if true hide mesh, if not hide fp mesh. something like that maybe?

[obsidian cave]

hey guy
i have a small problem >
i have a widget which has 2 subwidgets now the subwidgets are same i.e they are a copy
problem is the subwidget is heavy on processing, so i dont want to process it twice....i was wondering if there was any simpler way to do it
where i create one widget and render the same widget on an image in the parent widget...that way i have two copies of same widget

[outer goblet]

By just hiding the mesh you can but if you retarget to fp arms then you dont need the 3d mesh at all unless you want both for different views.

[dull tree]

its multiplayer so i need 3d mesh

[outer goblet]

Then i recommend taking a look at the new AGR plugin on marketplace. His channel also has ton of tutorials on mp settings and functions and also a 3rd person true firstperson example project you can download that does everything you looking for with mp already setup.

[dull tree]

ooo

ok

thanks

[obsidian cave]

i am just looking for any kinda solution bp or cpp..😅

[nova ledge]

Ok, I honestly didn't want to send pictures at first because the layout is bigger than my screen to where it's visible to read, but I really need help, so prepare for a few pictures. Like I have said before, I'm trying to create a flying character that can also walk, but I'm having trouble with the landing and idle/walk animations when the capsule is up against the ground. It's stuck looking like it's flying despite when it has clearly landed (I have a print string set up) and the movement has been switched to walking. How do I fix this? Should I send pictures of the Animation Blueprint as well? Also, I apologize for so many pictures 😅

[obsidian cave]

i be sure... to not do it agin

i crosss my heartt🥶

[nova ledge]

sorry for so many pictures!

[outer goblet]

I'd say you can also get that battle royale template from devaddicts channel. It has the flying/skydiving/parachuting and landing and also vehicle functionality. I'm sure that will help or at least show you how he did it.

[outer goblet]

wrong tag. sorry. meant for @nova ledge

[nova ledge]

Okay, thank you!

[outer goblet]

I'm trying to understand what you trying to do. You parenting widgets?

[trim matrix]

@obsidian cave If you are worried about processing you can create the widget at event begin play and parent and unparent it based on your needs.

[trim matrix]

Thanks man.It is working.The main thing needed is air control variable.Initially it is not working bcz server overriding movement.After running those functions on server it is working.Thanks again

[obsidian cave]

The subwidget is just acting like a component of a bigger widget and it is being used in other different widgets as well

[obsidian cave]

The problem is I want to show both the subwidgets at the same time as a part of bigger widget as a component which can be moved around.

[nova ledge]

Um, sorry to bother you, but I looked at the template. My problem seems to be mostly with animations, and as far as I can see this guy doesn't have animations for the landing part yet. I took pictures of my codes because I thought it probably would help with solving it, but I guess I really should've sent pictures of my Animation Blueprint instead, or at least sent some along with the pics of the code.

My character lands perfectly fine, it's just the animation is messed up.

[obsidian cave]

Also sorry if I was not clear..but the problem is processing for the subwidgets as they rendering the graphs and not the parent widget

[primal smelt]

I have a static mesh where I have added my own collision boxes to in the mesh details. I have a situation where I just want to use the collision of the mesh and nothing else for a static mesh component in a pawn actor. If I were to add the mesh as a component and under rendering selected hidden in game, will this actually save on resources at all? From what I understand the mesh data and materials will still be loaded for quick reference, is that right? What I'm trying to work out is whether it would be more costly to do this than say just adding some boxes to match the location and extents of the mesh collision?

I have a duplicate mesh that is flipped vertically which is visible in the game (may be a lazy workaround to solving a problem I had with positioning the mesh in the world at the correct orientation but it' what I'm currently going with!) and uses the same materials as the mesh I wish to hide, so it shouldn't really cost any more on the materials front at least.

(This is more of a "best practices" type of question)

[outer goblet]

Um, I'm really not sure. I still learning aswell so if i give wrong advice hopefully someone that knows more can help. I looked through bp pics you sent and these anim ones aswell. When you land does the printstring print that you landed on the map text? or you get no debug?

[outer goblet]

Cos what i'm thinking is that if you not getting that debug message then according to the bp you havent landed yet. And i'm thinking that if you have a button to switch between flying and falling then in the anim bp you need to connect hoverflying to landing aswell i think, in case you crash land without falling or a crash animation maybe.

i need a virtual joystick that rotate the canon of my tank and move in this direction, i cant find any tutorial for this so plz help me

[odd plume]

How can you check which player enters an input? I am working on a two player game, local multiplayer. Player index?

[slate harness]

How i can find that because i found nothing for a joystick to move

only for movement

[odd plume]

https://duckduckgo.com/?q=virtual+joystick+ue4&atb=v265-1&iax=videos&ia=videos&iai=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DNLj7XhfhnYo Here is what I found

You will need to adapt it for your needs

[slate harness]

thx you man

[odd plume]

Is there a better way of doing this? Trying to check which player answers the question first. Not really sure how to get the index as a boolean

[primal smelt]

I have no experience with multiplayer but I would imagine you'd probably want to store a variable with player controller ID at the point they submit their answer. At this point in your code where you presumably want to reward the quickest to answer you could check the variable against an index of stored IDs and then allocate points or what have you accordingly

[nocturne zealot]

Hi

[nocturne zealot]

Is there a way to make this in blueprints?

[primal smelt]

Something liek this maybe

(although by default I believe profile 0 is player 1 so you might want the default variable to be a number beyond the max number of players)

[odd plume]

I am using 1 and zero

[primal smelt]

Then you could have 2 as the default "no player". There may be another way of doing it - subject to the rest of how your code operates of course - but this is a simple method to follow for starters I feel

[odd plume]

Thank you for you help, I am a bit confused by this part

What is this doing exactly

[primal smelt]

So if you had "no player has answered yet" as 3 (0 in the screenshot) then when a player answers this checks what the current "value for "fastest" is. Is it 3? Then nobody has answered yet, so get the controller ID that is controlling this pawn and overwrite "fastest" to their number (0 or 1 in your case). When the other, slower player answers. The check will run, see that the current value is not 3 and so the "fastest" variable will not be overwritten.

Again though, I have no experience with multiplayer so how you'd get both players reading and overwriting the same variable, I couldn't tell you

[nova ledge]

Yeah, I had a print string and it said I was landing when I used the "On Landed" event. I couldn't figure out the problem but I found a workaround by using an anim montage, and now it works the way it's supposed to. I appreciate you trying to help me out!

[teal trench]

Guys, this is my graph for getting my character list, then add the character icon on screen with "add child to verticale box" and it works. But actually I want to pre-make the images in the designer and just assign the characters icons into them after. Anyone know how should I do it?

[outer goblet]

structs and enums. enums for the various types of characters and structs for the various data(icons health names,, abilities whatever)

[warped cairn]

So the distance between the player and the enemy is always 90, am I over complicating this?

The blueprint is on enemy...

To explain what the expected result is, if the distance between enemy and player is less than 20, then I want to take a value away from a float attached to the players blueprint

[teal trench]

I already have those data, how do i assign them on the image on my widget?

[outer goblet]

from a tut i did. The enum in this case repreents an ability and the struct holds the abilities data.

[gilded swan]

Hi how can i get from linetrace hit result the hit angle?

[outer goblet]

wouldnt it be easier to create a collision sphere around the enemy which deducts health from the player when in range? then you have a set distance to control all the time maybe with that can create a function to increase damage based on how long the player is in range?

[outer goblet]

the hit normal result i think.

Hello guys, i have a BaseEnemy parent class that i use to as the base to make new enemies, i was wondering how can i exclude some of the functionalities that are inherited? For example the parent class can do ranged attacks, i don't want the children to have that ability etc.

ik but i need the angle

[outer goblet]

make them instance editable by creating variables. bIsLongRange for example

[outer goblet]

hold on. need another project open for this one lol

[trim matrix]

oh... so like add a branch check before the actions and then tick on and off the bool on each child actor?

[outer goblet]

basically yeah. similar to how your firing system switches between guns. How does each weapon know its a pistol or rifle.

i'm looking for a way to not lose the class, it's a shit ton of code

[narrow kelp]

First see if everything is fine when you delete the file

or move it out of the project

I've had something similar happen a few times, and always had to revert changes

[outer goblet]

i was looking for a project where i could show you an example but i don't seem to have it now. if i find it will send a screenshot.

[runic parrot]

i tried copying the same class from the backup project and it doesn't crash, i'm gonna see why it's crashing

the modification i made shouldn't be making anything crash : (

i can't even run the game, if i try to even open the folder where the class is, the engine crashes.

i'm just redoing it from my backup and before doing the change that broke everything, i'm gonna backup again and see why it's happening

[maiden wadi]

Are you just looking for an angle distance? As in, is an always positive number fine for your result?

Anyhow. If that's the case. This should get you your degrees.

I have this to make the tank rotate but how i can make him move

plz

[fading fog]

you need to actually change the current actor rotation

so you need to add rotation to the current actor rotation

[slate harness]

how i can do that plz im new to ue4

i have some base in ue4 blueprint

[fading fog]

i will dm you a print screen with the nodes

[slate harness]

ok thx you, you helping me a lot in this project

@fading fog i think i figured out

I need to get the actor rotation and combine with the actual script

[fading fog]

yes, that is true

[nova ledge]

I've been brainstorming, but I haven't come up with anything solid as of yet. I'm looking to make my flying character speed up or down based on what angle the camera pitch is at and glide. Say if it is -45 degrees, the character speed will be at 400, and the pitch goes to -90 and the speed is set to 1000. I want it to ease in and out of the speed, especially if the camera pitch goes from -90 to 0.

What I mostly want is the character to slow down over time when the camera goes from -90 to 0, while when the camera pitch is 90, it's slower than when it is at 0. I keep thinking using a timeline for this will be good, but I'm not 100% sure how I would go about that since this will be my first time using a timeline. If I can use a timeline for this, how would I go about using it in the way I need? If not, what can I do to achieve my goal?

[slate harness]

I just need to add a direction input, its that right

You can use a map range, tick and finterpto to get the desired behaviour.

anyone knows how can i set my ball position to - x not changed, y to 220, and z not changed

really dont know how to do it

i made it like this, but it doesnt work

it doesnt work

i should change it?

and it will start working?

i did it rn

it was without first sequence

before

it should be like this?

no

those are fixed like 1000 years ago

just forgot to remove them

frick me

i think that was a problem

i just didnt saw it

let me check

Just want to point out too, these are functionally equivalent.

Sometimes it's neater just to keep them in a row than using a sequence.

okay, ty

still doesnt wokr

[hexed coral]

is there a way to bypass/interrupt a delay node?

[faint pasture]

@hexed coral sort of common not really, what are you trying to do?

You could have a switch before the delay and bypass it that way, but it sounds like you're doing something sort of f****. What are you trying to do?

[hexed coral]

I made this custom for each loop with a break and it works with a delay. once the loop has been broken i want to dismiss the delay.

[faint pasture]

You should be able to structure the loop macro such that when you break it, it bypasses the delay.

[void needle]

i fixed it

ty all

[hexed coral]

I tried adding a boolean or setting a variable to 0 but i had no luck with it.

[faint pasture]

@hexed coral I take it you have a gate involved somewhere? Just have the brake close the gate and then exit. Whatever delay is currently running, it'll re-enter and hit a closed gate and not do anything

[hexed coral]

I dont think i have a gate let me check

I used the 2nd macro from this video and combined it with the default for loop with break node: https://youtu.be/8D_QOZc-EPM?t=114

It doesnt have a gate It just has a boolean like the default for loop with break node

[nova ledge]

Hmm, I tested it out, and I realized it's not quite what I wanted. Maybe I didn't include enough (or slightly off) details in my message, but what I'm looking for is when the pitch goes from 0 to -90, it speeds up quickly, but when it goes from -90 to 0, it slows down slowly, as to apply the effect of gravity helping the owl character go faster when they're level but eventually go normal speed. What I'm looking for is similar to how the griffons in ARK glide due to that gravity effect.

[narrow kelp]

@hexed coral try adding a check after the delay

[dawn gazelle]

Then adjust the interp time based on the current speed - you can use a map range for that as well.

[faint pasture]

I take it you have some sort of acceleration or desired direction vector (camera forward?) However you're calculating direction, dot it with (1,0,0) and map range or use a curve to transform the 1(straight up) to -1(straight down) space to your desired max speeds

Map range will make it a linear correlation. Use a curve if you need it different.

You can also use the pitch value into map range if you want, either one. If you need a nice smooth transition, somewhere in the chain, make a value a target value and then finterp towards it.

[trim matrix]

Howdy, if I have two vector locations, is there a way to get the rotator values of one of those vectors with respect to the other?

basically this

Thank you I shall try it!

[slow phoenix]

I think there is a node that calculate angle between 2 normalized vectors

Also a node that calculate rotator so you can rotate from one to the other

Yeah, I read the question again and post the 2nd one

It gives a quaternion so it only goes one way.

You can inverse the quaternion I think to get it go the other way.

[sharp umbra]

Hopefully quick question / answer. I'm following a guide for creating a game and I've created a laser and working on the enemy, I'm attempting to get a print string for my event hits with the laser, but it's not really hitting anything even though I have the collisions set up properly. It's even not hitting the walls of the basic third person room it gives you with a new project, just goes through them. This guide has 70k views so I assume many here have seen it, when he shoots the laser gets stopped by walls, boxes, stairs, the enemy, mine just keeps going through things. Is this a forehead slap of stupidity moment? Anyone have advice? very very new to the engine.

[trim matrix]

Are you using a LineTrace?

[sharp umbra]

Genuinely don't know what that is lol, wasn't mentioned in the video so no

[dry pewter]

Hello everyone

[trim matrix]

Ok well I had the same issue yesterday and I solved it

Here's how I did it

Use a function called "LineTraceForObjects"

Where you make an array of all the object types you want to hit, and the hit result variable is very customizable as you can see.

This worked for me

[sharp umbra]

Ok thanks I'll give it a shot

[dry pewter]

I'm a bit lost here, i am setting up a character movement following UE documentation, but i need my character to end it's movement facing the direction it was moving along, how should i do this, my idle animation after movement is always facing forward

(forward direction before starting movement)

[trim matrix]

how are you setting your input controls?

[dry pewter]

This is the characters bp

[trim matrix]

Can I see your inputaxis settings in the project settings?

[dry pewter]

That'd be this

[trim matrix]

And what is currently happening when your character ends it's movement?

[fleet cedar]

my project broke today 😦 was working on it fine last night

Any suggestions?

[trim matrix]

hmm well not sure

[dry pewter]

I have my 4 walking animations as "walking forward" but facing right, left or back respectively. When i stop pressing a movement key the movement stops and the character turns around to face forward

[trim matrix]

maybe your system is not allowing UE to access the project files? It happened to me often with Windows 10 with other programs I used. Just assuming that as the error message says "access violation".

[dry pewter]

Do you have your project files on a cloud storage folder like dropbox?

[fleet cedar]

Nope...

[dry pewter]

That's all i can think of, sorry (As i had the issue when working from a dropbox folder)

[narrow kelp]

delete your most recent files one at a time

and use source control as backup

[fleet cedar]

;_;

[trim matrix]

So when you stop moving, the variable "Disable Movement" is set to true, correct?

[dry pewter]

No

[fleet cedar]

Okay I will try this @trim matrix

[faint pasture]

@dry pewter You need to formulate it like this. You need to determine if you want the character capsule rotation to be driven by aim or movement. Then whether or not you want your upper body or lower body to align with capsule.

[dry pewter]

I need it to be driven by both

Kind of

I'm trying to set up a blend space with only idle animations and see

[faint pasture]

@dry pewter in your strafe animations, is the character running forward or looking forward?

[dry pewter]

In the walking animations the character is facing in the direction of the movement

[faint pasture]

That's a good fit for "orient rotation to movement"

Then the difference between aim and movement directions is what drives the blend space.

But you need a "idle but aim left" pose, not sure if you have one.

[dry pewter]

Yes i just made them and i'm trying to set up a blend space

Not working tho

[dry pewter]

Should i change my character movement class defaults?

[pastel rivet]

How can i convert floats to range between 90 to -90 for set rotation?

[dry pewter]

Use "Make rotator" node

[pastel rivet]

@dry pewter
I still cant go past -90 or 90

[dry pewter]

Where is your float comming from? what's the range such float can have?

[pastel rivet]

@dry pewter
Im using a controller, and ive tried using add relative rotation and set actor rotation, but theres a limit to it, it can only go 90 degrees before it stops totally and starts wiggling

im using the controllers axis value

[dry pewter]

Why not 'add movement input' instead of set actor rotation tho?

**Add controller pitch/yaw input

[pastel rivet]

The actor is not a pawn which im trying to move

[dry pewter]

@pastel rivet Do you have any way of checking what the value of the axis is as you testplay? maybe the axis is not going from - values to + values but only from 0 and onward?

@faint pasture @trim matrix Solved it, had to turn off use controller yaw on character itself, not the movement component

[upbeat otter]

https://www.youtube.com/watch?v=Z1rmvlrlSBY having this problem with aiming on a planet rotation, how would I switch the rotation to work from the side of a planet

here's current rotation code

i feel like its simple but i can think of how to solve it

[arctic cradle]

Anyone know some quick tips or possibly tutorials on merging different blueprints and kits? I think I wanna merge2 kits that don't offer the same things, but I'm always hung up on the Game Modes and Player Classes. Would it be as simple as opening my main Game Mode blueprint and copying and pasting the other into it? I've seen a video or two on YouTube but have never really been able to wrap my head around it.

[sand shore]

Not likely

[slow phoenix]

lol, yep not likely.

[sand shore]

Move all the data structs and enums from pack B into project A.

move all non controller/pawn/etc from B into A.

Make a new folder for B in A, move all remaining content (eg, main GameFramework classes) into A. Open and copy functions over starting with functions that don't call anything else in their classes.

[slow phoenix]

I mean if they implemented really good base classes, you would still need to properly go through the blueprint/code to make sure.

[sand shore]

You can't avoid figuring out how to merge them on a member-by-member basis

basically move smaller chunks of logic before larger chunks, and migrate in editor only

[slow phoenix]

also, if deem possible, you can extract some out into reusable blueprint function/micros, etc.

[arctic cradle]

yep, figured as much, thanks for the help though haha

[uncut lark]

What collision would detect a linetrace? Im trying to make a hitbox from a capsule collision

[slow phoenix]

You mean you want to fire line trace at a collision capsule or you want to overlap hitbox with a collision capsule?

Cause you can filter by object type using the line trace for objects.

[uncut lark]

I want the enemy to have its own hitbox seperate of the capsule component

[north hedge]

All of them should technically, if its got blocking on in physics for Camera/Visibility then it should hit

CSGO has a nice neat photo of capsule based hit-boxes if you're looking for an example, but I'm pretty sure thats photoshop and not in-engine
https://static.wikia.nocookie.net/cswikia/images/c/c8/Csgo-hitboxes-20150915-update.png/revision/latest?cb=20150916093336

[uncut lark]

So block camera and physics, got it.

Im having an issue with the enemies attacks getting blocked but Im not too sure whats blocking it. I need to figure out collisions now.

Like if it fires out the trace from its origins, something blocks it

[north hedge]

Print the hit actors name, that should give you a start

Also block Camera and/or Visibility based on what you're using

[uncut lark]

Cool. Ill do that

Thanks!

[sterile quest]

How do I resolve this error?

I can't move my skeletal mesh with the BP I've setup

[sterile quest]

Ya I am stumped. Guess I'll have to throw in the towel tonight.

There's literally nothing online that has been answered for this problem.

https://forums.unrealengine.com/t/warning-attempting-to-move-a-fully-simulated-skeletal-mesh-vehiclemesh/81094
This dates back from 2016, 5 years ago. No one from Epic or from the community either answered back or was able to resolve it.

My BP is broken now because of this error because the movement setup I have is being entirely ignored. Really frustrating honestly.

Man UE4 is such a mess at times. Lack of fleshed out documentation and (more often then not from what I've seen) silence from Epic staff only makes it that much more disheartening.

[fiery glen]

my first guess is to try checking the Teleport bool where you move it?

here's the underlying C++

bool USkeletalMeshComponent::MoveComponentImpl(const FVector& Delta, const FQuat& NewRotation, bool bSweep, FHitResult* OutHit /*= nullptr*/, EMoveComponentFlags MoveFlags /*= MOVECOMP_NoFlags*/, ETeleportType Teleport /*= ETeleportType::None*/)
{
#if WITH_EDITOR
    UWorld* World = GetWorld();
    if(World && World->IsGameWorld())
    {
        if (FBodyInstance* BI = GetBodyInstance())
        {
            //If the root body is simulating and we're told to move without teleportation we warn. This is hard to support because of bodies chained together which creates some ambiguity
            if (BI->IsInstanceSimulatingPhysics() && Teleport == ETeleportType::None && (MoveFlags&EMoveComponentFlags::MOVECOMP_SkipPhysicsMove) == 0)
            {
                FMessageLog("PIE").Warning(FText::Format(LOCTEXT("MovingSimulatedSkeletalMesh", "Attempting to move a fully simulated skeletal mesh {0}. Please use the Teleport flag"),
                    FText::FromString(GetNameSafe(this))));
            }
        }
    }
#endif```

what are you doing to the skeletal mesh to move it?

[sterile quest]

There is none.

Like I don't have any nodes that have such a checkbox.

[fiery glen]

how and why are you moving it?

[sterile quest]

Moving it because...it's a ship? So it moves. How, can you please elaborate?

[fiery glen]

I guess I mean which specific nodes are being used here

ah,

[fiery glen]

https://answers.unrealengine.com/questions/699066/attempting-to-move-fully-simulated-skeletal-mesh-e.html

looks like the issue may be the physics assets of the skeleton itself causing MoveComponentImpl to get called that way

[sterile quest]

Thing is the answer talks about fixing a issue with a ragdoll. Ships don't ragdoll. So a bit confused

[fiery glen]

but it's still a skeleton with a physics asset

[sterile quest]

Okay. I'll check it out then

I am in the PhaT editor and first I don't see my root bone. I do see it in the mesh and skeleton but not the PhaT editor. Second how do I add a rigidbody?

[fiery glen]

''right click any bone and you'll be able to add/replace bodies"

I'm honestly not 100% sure this is the right choice for you as it's just me googling the error message and parroting other people

[sterile quest]

No such option

[marsh seal]

anyone know how to use this "audio intensity" feature in the river splines? is that just some data that i can set so i can get that value later in code? or is that like... something thats already implemented and i just insert some ambient sounds?

[fiery glen]

Try Add Shape

[sterile quest]

That's for collision. Thing is I am using a UCX collision as this is a complex shape.

[fiery glen]

you may need to have a dummy rigidbody in there set to kinematic just to make the warning go away

even if it doesn't get used for anything collision related

[sterile quest]

Okay. I'll try making it really small

[sterile quest]

Ya if I am doing it right, it made the entire mesh go flying and spinning into the air.

[fiery glen]

lol, woops

you could probably turn off the actual collision of the root physics rigidbody

[sterile quest]

I had to create a constraint between the root collision I made and the ships hull

Which I then set the translations for that constraint to "Free"

Even set Collision response to disabled

However that does get rid of the error.

Even if the ship is flipping up into the air...

The ship flying into the air, with the sphere that represent where I want the water line still above the water

[fiery glen]

the way the skeleton's physics asset is supposed to look is a mystery to me

so I'm gonna have to say "I have no idea"

[sterile quest]

Hey guys, is there a reason my skybox never goes past the sunset?

[zinc flicker]

I currently play around with Jump Animation but what ever i do it feels so sluggish or dull or strange.
I tried to make a timeline so that after the jump he falls faster on to the ground to make the jump more smooth and less levitating but it feels still very strange.

Is there a good tutorial to make smooth nice Jump via Blueprint?

[sterile quest]

@fiery glen Vehicle template doesn't have a rigidbody attached to it at all

Well the root (that epic named Sedan_SkelMesh) doesn't have a rigidbody

[fiery glen]

I just googled the error message man, everything else is a guess on my part ¯_(ツ)_/¯

[sterile quest]

UE4 seems like abandon wear in terms of Epics support for it and it's community. With the community being the ones having to figure shit out and Epic having moved onto their work with UE4.

Because there are NO answers that I've been able to find for this error.

Other people who have had it? Sure, but answers? None

Just dead ends

[fiery glen]

Mesh sinks to the bottom. Funny because that's a good metaphor for my will right now

[mortal cradle]

I'm using for each loop which checks through 50 spawned actors with "get game time since creation" node, when I use standalone it shows me to have 0.0-0.1ms performance hit, which looks a bit crazy because I though that this will take a lot of performance, am I testing something wrong or maybe that for each doesn't sound too heavy?

[surreal peak]

You should use the Profiler or Unreal Insights to test performance. Can't say how accurate your test is. Should also be preferably done in package builds

[mortal cradle]

Will do, thanks

[burnt nest]

I've tried reading up on the convo here. What are you trying to do exactly? Your ship is simulating physics, which is rather unusual for your purposes. It also has gravity enabled, which is making it sink to the bottom without something to counteract it and act as buoyancy. Also when a rigidbody shoots off into space it means it's overlapping something, and once it's been forced off of the other object, it will shoot off.
I would recommend not using physics for a ship. Otherwise you have a bit of coding to do to make it act like you want.

[mighty linden]

I've actually been trying to figure this out too. I have 1 water texture encompassing my map

here

I just want to set up a simple moveable boat on the water

But im not sure hpw to go about it

would it require a lot of coding ?

I quickly made a boat mesh for it too in blender

[burnt nest]

Depends how realistic you want the boat to be. You could just restrict it to a plane on the Z-axis to keep it at the water line.

[mighty linden]

thats what i imagined

And it wouldnt be super realistic for now at least

but i want to set it up to where i can take control of the movement

It will be very basic like i said

I made it so when I press shift a particle gets created

why sometimes it works and sometimes it does not?

So should I delete the timeline and put a delay?

Its an old project I just reopened so I'm as lost as you honestly XD

yeah

I just noticed the output is not attached anywhere lol

I put a delay since that is what I want

But the same problem occurs

The solution is to put a delay before "shift" triggers again

yep

lemme try

this method does not work

I guess I did something wrong, heres the pics

@restive dagger complex as simple

or what do you mean?

[restive dagger]

like this ? https://gyazo.com/84feca1f799b7dc2bcbbbb1a80318e43

yes

[restive dagger]

is the complex collision mesh empty?

I tried it with a collision mesh as well

initially I had a real ship, one sec

It was like this initially

https://i.imgur.com/3LeGd5E.png

but that doesn't work either

[restive dagger]

set the wall to block all

[olive sedge]

Same result

and I'm pretty sure it's the ship because I put a default Cube 1x1 and it clips as well

[restive dagger]

does the ship clip with everything in the world or just the wall?

[olive sedge]

with everything it seems

Because a default cube should block but it doesn't

[restive dagger]

ok cool

check on generate overlap events @olive sedge

put it to true

https://gyazo.com/ca1598ab7df954934eba1edb83dd6e83

[olive sedge]

it's true

I just tried setting my ship to a simple cube

but that doesn't collide either

[restive dagger]

https://i.imgur.com/EXtr0RI.png its not in your picture

also is it your pawn ? like the ship you are controlling?

[olive sedge]

yes, it is

https://i.imgur.com/4PaLBOU.png

this is new with just a cube

I tried BlockAll too but same

[restive dagger]

go to the physics asset of your mesh

https://gyazo.com/d4af410be336c35322be0c0f769578bf

and check the collision response

[olive sedge]

I don't have that

probably because it's a static mesh

[restive dagger]

oh um

[olive sedge]

I've been meaning to add movement in the mesh but it's not a priority rn

[restive dagger]

set can character step up on to no

[olive sedge]

I switched from complex as simple to complex and simple

and the collision works

[restive dagger]

nice

does it then use my collision mesh?

and can I scale the collision mesh?

cause it doesn't show up when I do show Collision

@restive dagger the simple and complex doesn't get me very far.. I need the custom collision mesh applied

@olive sedge yeah use the complex collision as simple

https://gyazo.com/6b5de29f282e3f636c06e42e23260afe these are my settings I used for a static mesh

and check the collision mesh settings too

set it to block all

it should work

like theres no other reason for it not to work tbh

[olive sedge]

https://i.imgur.com/We3XZhc.png

this is what it looks like ingame

the custom collision mesh doesn't show up

I've set the collision mesh to block all

[restive dagger]

yeah custom collision is always not visible

[olive sedge]

oh ok

well, in any case, the collision doesn't work

only if I go complex and siomple

but I think that would not apply my custom collision and the collision profile would change with the model. I need to avoid that

[restive dagger]

One min

Send me the custom collision details and the ship mesh collision details again

The way it looks you are doing everything fine there must be a small mistake

The whole point is to move the target actor to a specific location, then after that I will attach them to a socket.

[restive dagger]

collision mesh is set to vehicle

not to block all

set the collision mesh to block all, and the ship collision to vehicle.

[olive sedge]

@restive dagger I did, same

[restive dagger]

in the collision mesh details set the collision complexity to project default

my project default is complex as simple 🙈

you cant add animations

capsule component as the collision

then the mesh

[olive sedge]

@spare vessel I don't know that you can do this from blueprint but you can from sequencer

[restive dagger]

then everything else

[olive sedge]

@restive dagger can I set the capsule collision to ignore and then sub component to block?

[restive dagger]

well that would make no use of the capsule component XD

[olive sedge]

yes, I don't want a capsule component

this is what I need: https://i.imgur.com/NTerzsU.png

[restive dagger]

honestly I never used a complex collision for my pawn, I usually use them for static meshes not pawns but I guess that wouldnt make a difference

[olive sedge]

just a littler tighter

[spare vessel]

@olive sedge Yeah it seems to have been removed it was a node but I can't find anyway of accessing it

[olive sedge]

@spare vessel well, not sure why you would want a node. just hit render in sequencer

[spare vessel]

@olive sedge trying to do it from a built game

[olive sedge]

@restive dagger yes, it shouldn't matter if it's on a pawn or a static world component I think

@restive dagger I'll try setting the collision mesh as root component and transparent and then adding in the ship just for visuals

[restive dagger]

Can you try to put your ship on the air and simulate physics

And everytime try something new in the collision parameters and see when it collides

Everything is normal there might be a small unchecked parameter thats doing all of this

how to add movies to package build?

i add video.mp4 in MyProject/Content but after build i can't load video

in standalone all work

[olive sedge]

When I apply a world offset to my object and it collides, it just doesn't move at all. Can I make it move at least in the direction it could?

Imagine the object going into a guard rail and then just stopping instead of being guided

[odd nova]

noob here- i was wondering, isnt there a better way to do it than this:

[gentle urchin]

Ammo / Max ammo

Probably stored in the gun anyways

For the other stats, not so much

[odd nova]

its not the guns ammo

its the total ammo

[gentle urchin]

Seems like it both

Current and max

[odd nova]

a revolver has 6 shots, 6 loaded, is the maximum
but you only have 20 bullets, so after the 20 bullets are up, you cant reload the revolver

[gentle urchin]

Inventory would hold the actual ammo the player has. The gun would have clip size and currentclipamount

Currentclipamount is reloaded from the players inventory amount

[odd nova]

i could move those ammo counters in the inventory, yes, that sounds good

[limber finch]

Does anyone know how to change an input via a key on UMG?
FOr instance, I have a checkbox, if the key is pressed, without being in UMG, I want that checkbox to be checked
So if the checkbox is checked in UMG, the action occurs, but if the player uses the hotkey to activate the action, the checkbox is then also checked on UMG

any ideas why 6-3 is 0?

[crimson hornet]

I just made an simple BP to make the AI spawn every 10 seconds at a specific place. My AI is BP based thats why it doesn't need an behavior tree in the SpawnAIFrom Class. But I got an problem the problem is that I made target points for the AI to go, I set those target points in the details panel in the level. But I need to select an Actor and an Pawn to spawn the AI in the world. Is there anyway I could select the specific AI in the level and set it in the Actor and Pawn?

[vivid plinth]

I have a static mesh component I want to use check for overlaps.. but no matter what I do, it does not return any overlap events. How can I use mesh as collision?

these are my collision settings..

[spark steppe]

have you checked if the static mesh has any collision shape? (in the mesh "editor")

[vivid plinth]

yes I have auto generated complex collision

[ember veldt]

Do the collision objects you're trying to collide with have generate overlap events on?

[vivid plinth]

yes both have generate overlap on

I'm almost positive I've done this before but I'm not sure what is happening this time. It seems rather simple

[proper wyvern]

has anyone here messed around with procedural meshes?

im getting the normals, which seem fine, but after I move it they dont seem to update

[devout geyser]

@proper wyvern I am not an expert but maybe it doesn't update because the function called once?

[proper wyvern]

it definitely isn't called once. It's called every time I hit a specific key

[olive sedge]

Can I get a vector of a new point x when I have a position V, a direction R (rotator) and a length L?

actually I have a vector 2 vectors and need to rotate vector 1 just a little bit towards vector 2

[mental robin]

Hm. Does anyone know how to get each static mesh of a foliage actor thats been painted

because with the foliage system in ue by default it groups them all as a single component..but I want to be able to access each individual mesh. If this isnot possible by default..then I have to create a system that plants meshes and puts them into an array I can access

and that will be one wicked pain in my rear end

[spark steppe]

and one wicked pain for your GPU, too?!

foliage rendering puts them in clusters to reduce draw calls

[mental robin]

yep

To be fair I am not so worried about it. It's only for specific things..not an entire field of grass

Only need to access a dozen give or take a few at any given time

[spark steppe]

idk if its possible, just wanted to get sure that you don't come up with the idea to put a thousand grass meshs in the world without foliage tool

[proper wyvern]

Does anyone know if it's possible to convert an actor into a static mesh component at runtime? Unreal has this tool in the editor but cant find it runtiem

[crimson hornet]

?

[fallen glade]

anyone know what this is?

"No value will be returned by reference. Parameter 'PathsCollected'. Node: Call AIPFPaths Collected"

[unique harness]

It means that if some object that is bound to this event and changes "AIFPPaths Found" this variable here will not change.

[vivid vapor]

Anyone know how to fix stuttering when using lag on a spring arm component? Lag on the rotation is fine but translation stutters depending on what Im doing with my character.

[summer bolt]

Don't think so but there may be some other work around.... what do you need to do

[proper wyvern]

I'm building a structure in single player (spheres, cubes, procedural meshes), which I want to bring to the multiplayer server at runtime

Imagine like a garage sort of thing, where the garage is your offline hub

[vivid vapor]

Can't you just remove the actor and copy its transform and spawn in a static mesh in its stead?

[summer bolt]

Alright I don't know much about mp but from what I understood you could have 2 separate ones and the offline one saves some data which is called in the miltiplayer one

[proper wyvern]

I guess this was more from some performance concerns (multiple procedural meshes and all). But I think I could use the original actor too

[fallen glade]

ok.... why just that one though? I have other calls and they are being quiet :/

thank you for the answer by the way, it's appreciated!

is it because it's an array? annoyng warning/error

[slate harness]

Hello everyone,
I have a little problem with my rotation
As you can see is going to fast for my eyes
How i can slow it down.

[maiden wadi]

@proper wyvern If you're really worried about performance concerns, these objects would be done inside of a building manager, which has multiple HISM components, one for each mesh type. And you'd save the data you need like type and transforms, and reconstruct that object in the different game.

[slow phoenix]

Use the interpto nodes

[tropic oracle]

I can't seem to find anything on player teleporting to another player all i found is teleporters and teleporting to another level

[olive sedge]

is it possible to calculate how a ray would bounce off a survace? I need that bounce vector

[slate harness]

This is what i have done, This is the right use to the Inter to node??

I think not because its rotate a little bit and go back to his startposition

[proper wyvern]

That's really helpful, thank you

[unique harness]

Think about Fortnite, every thing you can destroy is a single actor so if you set it up correctly, there's no extra work

[slow phoenix]

Your interpto speed value should not be 0

[slate harness]

ok

i'll try this now

I never used that before

[slow phoenix]

Set it to 0.2 and start tweaking from there

[slate harness]

i set 1 and its not moving 😂

[slow phoenix]

You can increase/decrease to see the result.

[slate harness]

how (Im pretty new to unreal, this is my seconde game)

[slow phoenix]

Just input in the box, hit compile and try again.

[slate harness]

ok i do that thing but nothing

Its maybe a bad collision set or something like that

[trim matrix]

Hello, where do I find the construction script in blueprint mode? I want to open it and I cannot find it

[slow phoenix]

Nah, you are using set actor rotation so it should reflect right away.

Also you need to hold the stick longer

[slate harness]

hmm

i send you a video

[slow phoenix]

Cause that's how you adjust the speed.

[slate harness]

Look @slow phoenix

[white lynx]

Hey guys, I made a class inheriting from UDeveloperSettings and extended that in BP for setting values. How do I set the BP Developer class to be the Engine's Default Developer Settings?

[mortal coral]

Trying to set up some super simple AI navigation, and the movement is failing. Is there any way to see a more detailed reason as to what is breaking?

[slate harness]

@slow phoenix

[slow phoenix]

Checking

1 is your camera parented to the tank?

2. Can you do a timeline or something else to test the rotation first?

Basically you need to make sure your camera aren't inheriting the actor rotation if you are using the pawn camera.

[slate harness]

Its working a little bit

just i haven't the camera shaking

[slow phoenix]

Lol, yeah that makes sense why it jitters like that.

[slate harness]

The spring arm was parented to the colision box

[mortal coral]

I can provide more info if it would be helpful; unchecking "Use navigation" causes the movement to more or less work (but of course, i need navigation). i have a nav mesh, that looks reasonable when i press P, and the movement result is simply "failed" if i check use navigation

[slate harness]

i think ist rotating

No

With interp at 0.2 its not rotating

[slow phoenix]

Well, if you rotate the "actor" then everything is rotating with in your structure of components.

It's like you rotate a house so all the window, doors and everything inside the house will also rotate

[slate harness]

ok but what i should do

??

[slow phoenix]

Well there are quite a couple ways to do

But first thing first is to not use set actor rotation

[slate harness]

ok

[slow phoenix]

Instead use the rotate to rotate just the sprite.

Remember to pull your camera out as well from the sprite.

[slate harness]

but i want the collision to rotate

[slow phoenix]

I don't know the exact node to use buy if you look it up there should be a node to rotate a component

Well, then it's a bit more complex.

You can build a scene root as root component

Then rotate the collision box

[slate harness]

Rotate by world location (Papersprite) i found taht

[slow phoenix]

While camera parent to the scene root

[slate harness]

ok

[trim matrix]

can objects in blueprint mode have custom properties?

[slate harness]

Like that

[dawn gazelle]

Found this online - pretty sure it's right as it's using the "Impact Normal" which is the angle at which the trace hit.

[trim matrix]

can objects in blueprint mode have custom properties?

[slate harness]

@slow phoenix

[dawn gazelle]

Such as?

[trim matrix]

I'm just asking is there a way to make a custom property for an object reference, any sort of property

basically a variable inside of another variable

[dawn gazelle]

If you have an object, then it is of a specific class, in which case, you can put a variable within that class.

[trim matrix]

In my specific case, I have a set of gun objects that rotate up, down, left & right, and I want to have a way of setting each gun as "ready to fire" when it stops rotating. Upon me pressing the fire key, the code will execute a for loop for all the guns present, and check for each one if it's "ready to fire", and if so, it fires the gun.

Otherwise, it doesn't fire the gun.

So all I need is just a way of making a property that is a boolean for each gun object, and just using that as a "ready to fire" variable.

Hope that makes sense.

[dawn gazelle]

So you probably have a gun class, and then child classes based off of that, no?

[trim matrix]

The gun itself is not a class by itself, it is a static mesh object reference parented to the ship blueprint.

I apologize for wonky wording I'm not familliar with the UE terminology yet

this is the gun object

[dawn gazelle]

Ok, so what you could do is use a Map variable type.

Whenever you want to look up the status...

[trim matrix]

So is that a local variable?

[dawn gazelle]

This would be a variable on your ship blueprint.

[trim matrix]

Ok, and a map is a sort of array that holds values, correct?

[dawn gazelle]

Yep, it's an array in which you can reference a specific value by a key rather than an index, and that key can basically be almost any type of object or variable type.

[slate harness]

@slow phoenix

[trim matrix]

Excellent, I did not even know this was possible! I will show you the results of later of my work.

Thank you

[olive sedge]

Cool thanks!

[glacial belfry]

that helps me too!

[trim matrix]

@dawn gazelle oh and I almost forgot, how would I change the status of a map variable at any given time? What function to use?

[dawn gazelle]

This one

[trim matrix]

doesn't that function add a new one every time?

[dawn gazelle]

No, if the key already exists, it overwrites it

[trim matrix]

cool got it

[sterile quest]

I am using the Ocean Project because it has a endless ocean feature which the new UE4 water features do not have. So it isn't sinking to the bottom with gravity. I am trying to control the ship but I get that warming message that I posted a screenshot of. I did fix the issue with the rigidbody, however using the Kinamatics setting on the root makes it act like it no longer has any pontoons set, which you can see it sinking to the bottom.

Sorry about the late reply. Hopefully you are still around.

I am thinking about having the hull of the ship as a staticmesh rather then a skeletal one to hopefully get rid of all the headache that this has been giving me. And have the guns, rudder(s) and anything else that is a interactive features for the ship be a skeletalmesh. I am hoping this would remove the warning that is causing the movement for the ship to stop working to no longer being a problem. However this does mean I cannot use the socket system like I would have wanted to, and as I add larger and larger ships (which I plan to), it will become a very unintuitive process to have to manually place all guns and other interactive features. Which I'd rather avoid honestly.

[slow phoenix]

Dir you try it out yet? Lol

I am eating lunch so won't be replying quickly. Part of learning is trying out things and figure those out.

You should have good starting point so the rest you should try figure out. Ask when you run into issues again.

[low lava]

Sup! SO I am making a UtilityAI system or I am trying to! The Issue is, I am trying to connect a Construct Object to a Construct Function and I get an error: "Self object Reference is not compatible with UtilityTask Object Refereance"

I am trying to follow a TUTorial

Or uh

string of tweets

THis should be the end result

[unique harness]

TaskType array "Type" needs to be UtilityTask Class, it's probably Object class

if it already is UtilityTask class, recreate your for loop

[willow cedar]

I have a problem where when a character loads into the game, the player HUD is added again on top of existing players. I can tell because I have transparent elements that get less transparent when people die. How would I fix this?

[slow phoenix]

trace your UI widget create route and make sure it only do it once per player controller.

of course you maybe have different parts for the UI (say, when you are playing vs when you die, or opening the option screen etc)

just make sure it's not driven by something the creates new UIs and then added to existing canvas

[brittle knoll]

you might have to open the original to see this clearly but uh

so basically, i have an actor that orbits around my player based on the right stick direction

when i shoot (called in from player), the actor is supposed to move towards a location and stop, which works correctly.

when i return, it should move back to a certain distance from the player. however, for some reason, on the way back, the target variable gets set to the actor's current position, causing things to get screwey.

for the life of me, i cannot figure out when the target variable is getting changed. can anyone take a look and help me?

i can also hop in vc if anyone needs me to screenshare and show stuff off

im 95% sure this is something simple and dumb but for the life of me i cannot tell

[hybrid ether]

Anyone know about saving? I am creating system that when u kill boss it saves its ID. This obv doesn't work but how could I do that?

Should I first load game and add old IDs to list then save?

This is executed when boss dies and every boss have own ID

[vestal apex]

Quick question on Blueprint basics: I have multiple actors in a scene, all based off the same blueprint with basic movement functionality (I press a button and they all start moving in the direction they are facing). I would like to create different paths for each actor to move along (thinking waypoints). But as I currently see, any change to the main blueprint creates the same change for all the actors in the scene. Any ideas on how I can approach giving each actor it's own customized path?

[brittle knoll]

nm fixed mine, was actually an order of code thing

[slow phoenix]

Remember to expose your parameters for edit.

[hybrid ether]

I made it like this But is this good way 😄 It still works

How I doing same thing twice :0

but I have like other slots for saving character stuff etc.. but This is only for bosses so I can check "have I killed it"

Its for teleport system that I can "skip that boss if I have killed him" next day when play again. Then teleport checks have you killed that boss and unlock button to load level after that boss 😄

[upbeat otter]

how would a character rotate on a planet? because traditional rotaiton like control rotation does not seem to work

well i have a gravity system set up but i cant rotate the character on the yaw

its gets very confusing

here's an example

is a pawn easier to control rotation?

would there be a way to transfer my current character to a pawn?

[low lava]

This fixed it for me ! I swear I had it set to Utility Type. I think I had to re-create the loop like you mentioned! Thanks so much

[prisma stag]

Hello, Im working on an inventory widget however nothing happens when I click on the buttons except the fact that the widget disappears. I believe it has something to do with the input mode. BP for showing inventory

BP for clicking on button The print string was added and doesnt get shown when I click on either button.

It continues to show the inventory.

Why? Thats like having a hold button in a game rather than a toggle.

[rare gale]

Are the buttons behind anything in that inventory? Also, double check they are visible and not NotHitTestable or whatever that setting is. I had some stuff default to that the other day for some reason.

[prisma stag]

Visibility is set to visible and the button are just behind some text.

In the game I can see the button get pressed as it changes its shade slightly but the print string never fires.

[rare gale]

Do you get the normal interaction when you mouse over them? Hover and pressed states?

[prisma stag]

Yea, when I hover they change their shade, then when I click they change their shade but the widget disappears and nothing happens that is supposed to happen.

[rare gale]

Stupid question... do you have the bool checked on the print strings to print to string? Other strings are printing and you see them?

[prisma stag]

Yep.

[rare gale]

that probably is the problem like Lorash said... if it's supposed to clear, it's going to remove code after it which would remove the print string. Try a delay after the print before the part that removes widgets maybe?

Depends on what's removing it I guess

[prisma stag]

Oh wait. I wonder if clicking on a button removes the widget and set the input mode to game only before the code after clicking can do anything?

[rare gale]

might cancel the press being held and automatically releases?

[prisma stag]

Maybe.

[rare gale]

try a flip flop between press and release code from one or the other and see if that works

[prisma stag]

Ill have to mess around with it for a bit as having a flip flop if what Im trying to avoid.

[rare gale]

I think you may need to hide the widget screen rather than removing all. That is likely the issue there

[prisma stag]

Does just hiding it still allow you to click on it? Ive only known to remove all.

[arctic cradle]

So, I've got JVD's grapple component and Dialogue Plugin going concurrently. GC has a great rotation feature built in, and it's perfect for dialogue setting. NPCs snap to me, I can control the duration and animations, it's great.

The issue I'm having is that I have a hit box to begin dialogue. It passes, it begins the dialogue. Awesome.

But, how would I go about multiple NPCs? As it stands, I could have 5k NPCs, and with this set up they all will say the same things.

I was thinking of doing an array and for each, but even then I'm confused how to implement it.

How would I go about making sure each NPC states their own dialogue?

[rare gale]

You'd want to hide after you've clicked I think?

[prisma stag]

Right, but the code I have already does that, but in my case it is completely removing the widget and then creating one when I hold again. I dont know if in your case I can still click on it or not knowing that all Im doing is hiding it.

[rare gale]

You wouldn't be able to click while it's hidden for sure.

[prisma stag]

Gotcha. Ill have to look into it, thanks.

[rare gale]

I'd try doing the flip flop just to test that it's trying to do what you expect without removing. If that works, then try hiding rather than removing. you may have to change up some timing or where things get called once you figure that out.

[prisma stag]

Once I did the flip flop it did what I wanted, so Ill have to see what I can do as the toggle is not what I want.

[smoky jungle]

hi guys, im want to make endless android car game.
what you see in the screenshot below is the blueprint of npc's
I want these vehicles to go straight and change lanes at regular intervals. how can I do that?. I do not want to give NPC vehicles physics and vehicle movement due to performance problems. How can I change lanes without giving these vehicles physics? I would be glad if you help

[trim matrix]

You can make a small function that you can call everytime you want to change lanes

and inside that function you add a repeating loop that slowly increments/decrements the cars' Y position (I'm assuming to move them left and right you will have to use Y as you're incrementing X in the blueprint image you sent to get them to go forwards).

And it stops incrementing/decrementing the Y when it moves to the other lane.

@dawn gazelle do you know why in the 3D blueprint editor viewport when I switch to an ortho mode, it always shows me a lower LOD of my object?

[brittle knoll]

Does anyone know how to implement rope swinging? Need my character in a 2.5d platformer to swing from the end of a grappling hook. Figured out my hook implementation, need to figure out how to make a rope and swing the player.

[odd plume]

I downloaded a widget that requires a Array of Structs, how can you make that in bp?

[dawn gazelle]

I'm going to guess it would be because you're setting "newtarget...whatever" after this branch - so long as the wayback boolean is true, this value keeps changing.

[sand bloom]

Hmm does anyone know whether it's possible to switch between the first person character template character and the flying template character or in this case pawn?

[dawn gazelle]

Sorry, no idea.

[sand bloom]

Like I have something set up that switches already kinda but it doesn't work properly

it seems the first person character project's player controller is c++

and not editable

[dawn gazelle]

Structures are just like variables. If you have the structure type already created, you can create a variable of the structure type, and then change the variable format to an array.

[sand bloom]

as you can see it does not work properly because it doesn't destroy actors and the spawn location is not updating

oh the flip flop isn't plugged in this screenshot but i have it bound to a key

does anyone happen to know whether this is possible

[dawn gazelle]

Where is this bit of blueprint? What BP?

[sand bloom]

this is in a new player controller I made

and I assigned this player controller to the gamemode

[brittle knoll]

already solved that and yeah that was it but thanks

[dawn gazelle]

Ok, so the issue is then when you're calling "Destroy Actor" you're not referencing which actor and that means you're asking to destroy the player controller itself.

[sand bloom]

oh that makes sense but how would I get a reference of the actor I need

I would have added something if there was an option to

[dawn gazelle]

That should work within the player controller.

and of course, if you're possessing a pawn 🙂

[sand bloom]

oh that's interesting thank you 😄 i'll have to try this

[dawn gazelle]

you probably also want to use the transform of your pawn instead of the controller.

and destroy the actor after you've possessed the new one.

[sand bloom]

yeah that does sound better, the transform apparently works now but the destruction doesn't, i'll have to tweak some things

[brittle knoll]

this got a bit buried but yeah if anyone knows how to do swinging lmk bc all the tutorials i can find are outdated or are about grappling to a point instead of hanging from a rope

[sand bloom]

hmm trying to change it made it break

i'm trying to figure it out but i'd figure i'd post it here too incase

[dawn gazelle]

You're unpossessing before spawning. If you do that, then get player character will return none.

[sand bloom]

maybe my unposses needs a target

oh

[dawn gazelle]

Also, nodes tell you what target they expect on them.

So like.. this is asking for a target of a controller Target is Controller

So if you're working in a controller blueprint, a target of self is completely valid.

Though, if you're working with a different controller like an AI or a different player (if you were doing multiplayer) or you were working on a blueprint that doesn't inherit from Controller, then you would need a reference to the controller you're wanting to target.

[sand bloom]

hmm thank you good to know

i'm still trying to make it work I appreciate the help

[dawn gazelle]

You're destroying the current player pawn. So after possessing, you're asking to destroy it.

What you probably need to do is:

1. Create a pawn variable called "OldPawn" and store a reference to "GetPlayerPawn".
2. Unposses.
3. Spawn your new actor using the "Old Pawn" transform.
4. Possess your new actor.
5. DestroyActor "OldPawn".

[sand bloom]

hmm I figured since i had a character and a pawn there would be no conflicts

thank you

ill have to try that

[dawn gazelle]

A character is a pawn.

Not all pawns are characters, if that makes sense

[sand bloom]

I thought a character was a step up from a pawn and had more functionality and was recognised to be different

interesting

that's very good to know lol

[dawn gazelle]

So if you call something like "Get Player Pawn" and the controller is possessing a character, that will still return a valid reference, as a Character is a pawn 🙂

[sand bloom]

ah yeah nice

[zenith trout]

does using a soft object refrence only work if the object in question is already in memory?

[trim matrix]

@dawn gazelle thank you, is there a way I can add 3D vectors to a static mesh component?

[tight schooner]

@zenith trout isn't that counter to the purpose of a soft object reference? Epic has a primer on it... https://youtu.be/K0ENnLV19Cw

[dawn gazelle]

The components themselves cannot have variables. You can use a map variable just like I showed you with the booleans, but instead of boolean, set it to vector.

and if you're getting to the point where you're wanting lots of variables on your static mesh, then you may as well create a new blueprint, add your static mesh to that along with whatever variables you want, then attach that blueprint to your main blueprint where your static mesh component used to be.

[zenith trout]

I found out what my issue was

asnyc load does not seem to work if its in construction script unless the object has already been loaded

[wind sequoia]

yes as its a function

[willow cedar]

Do Blueprint Interface calls always execute on server?

[dawn gazelle]

No.

[willow cedar]

Currently when I apply damage to somebody and it triggers the Health component to hit 0, the Blueprint interface gets called to do the death event on the character, but for some reason the Remove widgets goes through the Server Host alongside whoever died normally.

When I have another player die when pressing B, it doesn't activate on the server, but the Interface event does

[dawn gazelle]

There's no call to the interface in this view. When you're applying damage, you're probably running that on server, and you're probably calling that interface on the server.

[willow cedar]

This is the Character BP where the event is triggered from the call

This is the health component where the call happens

[dawn gazelle]

Begin play runs on server.

So you're binding the event while on server.

Then the server calls the event which calls the interface.

[willow cedar]

I had no clue binding things on begin play did that on the server

I'm still new to using components, but am I doing this the wrong way, or is it an easy fix

[dawn gazelle]

Begin play also runs on the clients. Any time something is added to the world it's begin play fires, so if that is only the server's instance, it runs its begin play. When a client gets a copy of that thing existing in its world, it runs its being play. So begin play will fire on all copies of the object.

To make it more difficult - you also have network relevancy which will make faraway actors no longer exist on clients, but still exist on server. When you get close to the actor again, the server will tell your client to spawn a copy of the actor again which, as you guessed it, calls begin play again on the client 🙂

[willow cedar]

Ah yeah, I can see how that is a problem

[dawn gazelle]

Has Authority is what allows you to control if you're trying to run something on server or on a client, depending on who owns the object of course.

[willow cedar]

Currently I have always relevant on so you can see people at a far distance

[dawn gazelle]

Generally:

[willow cedar]

My biggest issues have just been HUD related. I Remove it when a player dies and re add it when they respawn, but I had a lot of overlapping or this issue

[willow cedar]

Thanks for that. This should hopefully fix my problem

Actually, I can't use the Authority Switch on the Component

Would the Bool function work for it too?

[dawn gazelle]

Only if you feed in the reference to its owning actor.

A component isn't an actor.

[willow cedar]

Yeah

I'll see if I can get it working

[storm mirage]

hi im new on the server and a newbie on UE and i need help to hide my life bar on the main menu before to play

[arctic cradle]

most people have main menu as a separate level

[storm mirage]

it is

[arctic cradle]

so then you have two levels, one is for the min menu, and it loads in the next level(world). Make sure the life bar isnt even present in the main menu's world. i imagine its sitting there on event begin play, which you don't need if it's just a menu. only have the menu stuff on that world's bp/code

[storm mirage]

my life bar is on the BP of my thirdpersoncharacter eventbegin play-widget-add to view port, but the main menu lever is an empty level so i dont understand why it appear

[arctic cradle]

sounds like they may be referencing themselves. open up both separately, maybe take some screen shots so we can see what you've got going

[storm mirage]

this is on my thirdpersoncharacterBP

(btw ive got a drunk bar aswell xD)

mb find a way to hide it since i havent clicked on play button

but idk if we can code that in this BP

[arctic cradle]

whats the Then 3 connected to?

[storm mirage]

something else to fix a post process bug

[dawn gazelle]

Easiest but probably not the best way to fix would be:

1. Create a a boolean on your character BP called "In Menu" or something like that, set it as an "Expose on Spawn" and "Instance Editable" variable.
2. Create a branch between your widgets being created. Connect the false path to where your widgets get created.
3. Connect your "In Menu" boolean to the condition pin.
   Now depending on how you placed your character in your menu...

If you directly placed the character by dragging it in, then when you have it selected, you should be able to set the "In Menu" variable menu on it to true, thus preventing the widgets from being created.

If you are using a "Spawn Actor" node somewhere, right click on it and select "Refresh Node". You'll now see a "In Menu" boolean open which you can set to true.

So, I've got JVD's grapple component and Dialogue Plugin going concurrently. GC has a great rotation feature built in, and it's perfect for dialogue setting. NPCs snap to me, I can control the duration and animations, it's great.

The issue I'm having is that I have a hit box to begin dialogue. It passes, it begins the dialogue. Awesome.

But, how would I go about multiple NPCs? As it stands, I could have 5k NPCs, and with this set up they all will say the same things.

I was thinking of doing an array and for each, but even then I'm confused how to implement it.

How would I go about making sure each NPC states their own dialogue? I spoke with JVD on it and h had mentioned storing assets to the specific NPC BP, but I'm not sure how to reference them in the character's BP or where to go from there

[dawn gazelle]

If you're doing a hit box, aren't you getting a reference to the actor that it is colliding with?

[arctic cradle]

..maybe? hahaha, theres a lot going on in the grapple attempt function. but it's set up to where if your boxes overlap and the input key is pressed, it fires off. He originally made it for syncing animations.

I went ahead and said no, make it do dialogue.

[storm mirage]

it did not work

but ive found an other way

thanks for helping though

[warm summit]

I am getting an error from these Update Dial custom events. saying it found none "when accessing the widget" I do see the pulse go through when debugging, and I changed the name of the "BCR Widget WTF" from Root BP and it propogated.

I also got the Update events by dragging off that reference pin no problem....

don't understand

[arctic cradle]

And you know, the more I think about it the more confused I become. It's not even the fact I'm using GC. Even without that, if I had a very simply systems, press A for line trace-- how am I storing and assigning these assets to individual NPCs?

[dawn gazelle]

If you're going to do it that way...

[warm summit]

but when in DEBUG mode if I hover over the outpin of BCR WIDGET WTF, I get a message "this variable out of scope" I am not sure what my mistake is

[storm mirage]

seems way easier

Thanks a lot Datura ❤️

!= is way better

[dawn gazelle]

You either haven't set RootBP or the RootBP doesn't have its own BCR WIDGET WTF set.

[warm summit]

I believe it has to do with the fact that I am spawning the BP that is trying to get that reference.??

[dawn gazelle]

Sort of. If you're spawning "RootBP" is there something within that particular BP that automatically creates and sets the "BCR WIDGET WTF" reference?

[runic parrot]

hi everybody! i'm trying to do something after my animation is either completed or notify (screen below)
is there any node for just do what is next only once? no matter wich one is first.

i was thinking on a gate or a flag, but maybe there's something more practical

[warm summit]

no I am not spawning RootBP, its already in the scene, and I am able to update the UMG Widget if I do it inside ROOT BP,

this is inside RootBP

[runic parrot]

what is your problem? can you quote the message with the problem?

[dawn gazelle]

What blueprint does this exist on?

[warm summit]

This is in a Spawned BP

[dawn gazelle]

Ok, and in your spawned BP are you setting Root BP anywhere?

[warm summit]

to which I am sending data from RootBP, and then trying to update the UMG
