blueprint

[dawn gazelle]

or if you just wanted one and done:

(there's one specific for background color)

[slow zealot]

yeah but background image is actually an image for the background, right? not the highlight color of the text

[dawn gazelle]

there's a setting specifically for background color, mine is blue in this example

[slow zealot]

this is multi=line textbox

[slow zealot]

let me try...

that's the background color for the whole textbox

I mean when you select some text (with the mouse), THAT selection color

[dawn gazelle]

Could you possibly just set your popup widget to have focus?

[trail condor]

I was trying to find a way to, but I didn't see one.

oh wow.

[dawn gazelle]

Just feed in its reference to the target whenever you've created it and added it to the viewport.

[trail condor]

I didn't realize I could just grab the highest level object in the hierarchy and enable focus there. Thank you.

That did it. Thank you very very much ❤️

one more tiny detail, I can work around this, but I've got a function expecting a key event, but I'm using InputAction AnyKey, which just gives me a regular old Key. Is there any equivalent I could use that gives me a KeyEvent?

[wet steppe]

Dont know if this is right place to ask

nor have I ever got a reply from here much often but here it goes 🙂

How would I go about getting my actor to always face its target

ive tried look at with set rotation

reinterp to

but it just spins crazy

this being the actor I want the tip to always be forward facing target

right now it flies to the target side ways

even if I change the forward orientation. like right now its along the z axis

had it facing the x+

when perched upwards on the ground

still takes off and flies sideways

like do I want set or add

rotation

I added the camera thinking maybe I could lock the view to a target

Easy if it was AI but

this bugger not so much

If anybody knows of a solution please DM me or @ me

[gritty elm]

you are adding rotation to your pivot point of static mesh or actor, the pivot maybe on the center of static mesh, so it will rotate from it's origin.
You need to change or set pivot point of your static mesh or root point of your actor to it's tip, so it will change rotation from it's pivot point.
You can either change pivot point of your static mesh in blender or 3ds maya etc, and import back in unreal. The other solution is to add a fake scene root component in your actor and make the mesh as child of that scene component, and try to adjust the static mesh to lower down, and when you want to rotate your object. you need to rotate actual your scene component
@wet steppe

[maiden wadi]

Also the rocket should ideally be on it's side when in editor, with the tip pointing in the actor's +X vector.

[dawn gazelle]

This should be in the actor's BP. Doesn't need to be on tick, but does need to be on something that continually triggers (like a timeline). Orientation of the projectile should have the front facing X

The white sphere indicating forward on the rectangle below would be the correct way to orient your projectile

[wet adder]

Hey guys quick question I want to make the boolean game over true given they equal each other

I tried set but I just want it to become true

[dawn gazelle]

You need to connect the execution path

[wet adder]

sorry how do i do that?

im a little new

[dawn gazelle]

The > on the left needs to go to the > on the right

[wet adder]

ah yes silly me

it works now

appreciate it!

[iron bobcat]

Fixed it by redoing all UI related blueprints and then restarting the editor. So still no idea, what it was.

(it works now though)

[copper iron]

Hey friends quick question. Is there a way to use a substring to find an item's index in an array? I've been searching for a solution over the last couple of days and can't seem to land on one.

Essentially I would like to have a substring like "head" return the index number of more complexly named item such as 02_Gordon_Head

I'm currently loading files from a folder so the only consistent name between folders would be head so chances are i couldnt just type in a hard value in a string append node for the desired functionality

let me know if you guys have any suggestions! thanks!

[nova rivet]

Switch on string

[dense tulip]

Any of you know what could cause the warning ?

[nova rivet]

Map might work too

[trim matrix]

You can parse strings into arrays and then do 'array:contains', maybe that would help, not sure how you'd avoid massive 'foreach' loops, maybe there's a smart solution

[dawn gazelle]

You should be able to hover over the node or it'll tell you at the bottom of the screen in your compiler results tab.

[uncut lark]

I stuck an event tick with a .02 delay. Is that going to have a huge impact on performance?

[dawn gazelle]

I think it more depends on what you're doing on tick whether or not it's going to be an impact on performance.

Though of course, it's always best if you can avoid tick.

[summer bolt]

👋 have a quick question if a character has a sword being swung around What blueprint type should the sword be

[paper galleon]

Actor?

Depends on the nature of the sword though. It can also be a static mesh component. But if it can exists in the world as an independent item. Just make it an actor.

[nova rivet]

No, that would improve performance (assuming a lot)

[pastel garnet]

Are there any replacements to event tick that would not damage performance?

[uncut lark]

Gotcha. It just checks a value for a health bat

Er stamina sorry

[nova rivet]

Slow it down even more

Although getting a value on tick is going to be cheap

[paper galleon]

Timeline maybe. But that runs using tick also. But you have more control over it's execution

[pastel garnet]

Ah okay, will try that

[paper galleon]

Start, stop, reverse.etc

[uncut lark]

Ye I'll just bump it up a touch

Thank you

[nova rivet]

Np

[summer bolt]

Thanks

[tight schooner]

@pastel garnet tick is just an event that fires every frame; there's nothing uniquely heavy about it. You can control tick with the node, Set Actor Tick Enabled, which would be effectively similar to using a timeline. You can also change the tick rate.

You can also use a looping timer event (Set Timer By Event node).

[leaden dock]

ah without it it creates a new object from scratch

[tight schooner]

@leaden dock pass by reference is like... It doesn't make a copy of the input but passes that variable directly. And then your function or macro or whatever can "set variable by reference". So you can have a function that alters whatever variable that's provided to it.

There are a lot of "standard macros" that use it

[leaden dock]

or does it become its own object then?

[tight schooner]

Promoting it to a new variable? You're making an explicit copy of it in that case

[leaden dock]

ok then that tutorial i follow along is doing a bit of bad practice

[tight schooner]

Try using the node (I might get the name wrong here...) Set variable by reference

Or set by ref var. It had some weird name like that

[leaden dock]

i dont know why he's storing the inventory at all, since the inventory exists in the character

[tight schooner]

Afaik that's the intended use of a pass by ref input

[leaden dock]

he should only reference it, not store it in the widget

weird

[atomic solstice]

Does anyone know what these 2 nodes are? Really frustrating seeing hundreds of results for "Set" 😒

[leaden dock]

the first note is a multiply

the other node sets the tentacle scale variable to the output value of the - node

or wait

[dense peak]

isn't the fist node a cast?

[leaden dock]

cant be multiply

makes no sense

is it just a reroute?

[dense peak]

casts the int to a float

[leaden dock]

ah

yeah that'd make sense in that context

[dense peak]

actually it's float to int sorry

[nova rivet]

No you had it

[leaden dock]

nope int to float was right

[dense peak]

haha all the greens

and yeah second one sets your local variable wonderfully titled 'Tentacle Scale' but weirdly it's new scale is divided by 1

[atomic solstice]

gotcha, thanks. Ya first one is cast (int to float I think?). Not sure about the second one.

oh my bad, i understand now. Thanks @leaden dock!

[leaden dock]

tentacle scale is a variable in the blueprint

when you drag and drop the variable

you can pick if you want to get or set it

[wheat vigil]

how do i get all attributes of an asset in blueprint?

id like to enumerate to know what it contains

or how do i find the documentation where all attributes are listed?

[dense peak]

attributes or components?

[tight schooner]

@lone arch ask #graphics

[lone arch]

o ok sorry for that

[wheat vigil]

both

everything that unreal engine knows about an asset

my goal is to load assets that are closeby to a players location

and id like to know what options i have

[leaden dock]

hm i recompiled a c++ class that i also use in some blueprints and now all my blueprints throw errors even after recompiling the engine

does that mean i have to rewrite all my blueprints every time i edit the c++ class?

[maiden wadi]

It's not a hotreload issue, is it?

I really wish they would seriously just disable hotreload if they're not going to fix it. It's practically deprecated, hasn't been updated, and just literally doesn't work, and yet it's still enabled by default.

[leaden dock]

well i used the compile button in the editor

so probably that was the mistake i made

[maiden wadi]

Did you compile VS with the editor open?

[leaden dock]

should just close the editor and recompile if i made changes to a c++ class

but seriously thats a horrible workflow :/

[maiden wadi]

You get used to it.

Enable Livecoding. It'll keep you from compiling with the editor open. Then you can compile already declared functions. and only have to restart when making changes to a class constructor, or the .h file.

[tame pecan]

It happens for me in a plugin setting. If I derive a class from my plugin into the project content, it says "Invalid parent" each time I recompile. The current workaround to test the plugin for me right now, is to create all my test actors in the plugin content folder.

It sucks, but hey, it works to test the plugin atleast.

I remade the plugin and project to see if there's anything wrong with that plugin/project, but nope, same problem.

[maiden wadi]

Here is an article on the hotreload matter. It's annoying. But a few second restart of the editor can save weeks of blueprint work in the end. https://www.ue4community.wiki/live-compiling-in-unreal-projects-tp14jcgs

[tame pecan]

Mine is not about hot reload, I restart and compile

[maiden wadi]

Linked that for Karasa.

[tame pecan]

Ah, okay 🙂

[nova rivet]

Recompile an in-use DLL? Sounds like that would be a problem in almost any environment

[tame pecan]

Hot reloading is the devil. If you change in the header and hot reload, it usually corrupts the blueprint.

Usually a issue for newcomers, some of the students I've teached with UE4 have fallen into that trap

[nova rivet]

Attractive problem to get trapped by

[tame pecan]

I think it comes from coming from Unity, where you never close the editor and it just compiles

and they're like "oh a compile button, lets go"

[nova rivet]

Indeed

[maiden wadi]

I still don't understand Unity. I feel like I'm pretty intermediate in my UE4 skillset, good enough to definitely understand things when I read them... but every time I read a Unity doc to try and help someone here who's from Unity, that stuff just doesn't make sense. :/

[tame pecan]

I usually read unity forums for mathematical problems, because usually they have way more topics available rather than ue4 forum

[maiden wadi]

Well, code snippets are one thing. Math is kind of universal. But the file structures and the way they do things is just... Wut? I know I'd get it if I spent more than two minutes on it. I've never had that with Unreal though, even from the beginning.

[thorny relic]

One advantage of BP is the instant compile times and not having to restart the editor

Wonder if/when that UE4 scripting language will show up?

[tame pecan]

Don't need to restart editor if you use live coding (unless you change to header)

[thorny relic]

Well, if I'm doing C++ classes, I'm probably changing the headers often /o\

[trim matrix]

Unity is like clay, Unreal is like stone sculpting.
In Unity, instead of Actors carrying their own BPs, everything is created into a component. And components aren't smaller actors like in UE, they're.... you can say they're BPs that have no physical form, each with a BeginPlay, EventTick and other events

[thorny relic]

Even if you're using a lot of blueprints and just C++ for things you can't do there, you still end up wanting to create new global blueprint library functions ... and that needs changing headers

[trim matrix]

That's the best comparison that helped me, an intermediate-advanced Unity user to wrap my head around UE4

[thorny relic]

(I'd imagine hot reload would be safe for that use case, but...)

[maiden wadi]

Kind of makes sense.

[zealous moth]

does anyone have any resources on how to implement fluid-like physics? I am thinking of using spheres and enabling physics but I was wondering if there was a better way.

[waxen rose]

can one explain with graph what this nodes do? Get Forward Vector ,make rotator, break rotator , get control rotation

[indigo quest]

Yo, I'm wondering if it's possible to use a sphere trace and get an array of overlapping bones from a skeletal mesh?

[maiden wadi]

@indigo quest I have a feeling that would require a bit of custom work. If you could get the bone's length, it would be easy to use the already easy to get bone location and rotation to do simple distance checks to a start and end point on a line.

[dark crow]

Get Forward Vector gets the Forward Vector (duh) aka +X Axis

Make Rotator enables you to create a Rotator from X Y Z Floats

Break Rotator is the opposite, break a Rotator into X Y Z Floats

Get Control Rotation gets the current rotation of the Player Controller

You could use for example Get Forward Vector with Get Control Rotation to understand where the player is looking with the Camera

[waxen rose]

so the problem them fix let me move from x/y with the camera rotation value right?

[indigo quest]

I see, tho in my case the purpose I already have a start and end loc, I want to get all overlapping bones in a radius around the impact point so I can Set Bodies below simulate

basically flip the overlapped bones's physics bodies to simulated

[dark crow]

You could in theory decide the player movement based on the Control Forward Vector yes, for example if you press W your character to rotate and match the forward vector of the Control so it basically rotates towards where you look and moves forward

[indigo quest]

currently my hit results bone returns none in print txt

[waxen rose]

thank u so much

[maiden wadi]

Bit odd. You should get a bone print from a successful hit result.

For your sphere trace issue, you'd need something akin to this. Although you'd still need the bone length for accuracy because you would want to get the bone's end point as well to test that, since if it's a long bone and you hit the end of it, and the actual location is further than the sphere trace, this wouldn't work, so..

[stray island]

Does unreal have quick copy pasting plugins or anything? Like Hover copy paste , so i hover a color and click ctrl + c then other color ctrl + v without right clicking each

[maiden wadi]

Er. Backwards on the <= test.

[indigo quest]

you are right, for some reason it's unsuccessful hit, Also Dude thanks so much thats exactly what I was looking for, filtering the bones in a radius, you're a godsend

btw If you're interested, I'm using it for a wood chopping system, to fracture rigged chunks on the location where the axe hits the tree

[maiden wadi]

That sounds much more interesting right now, than setting up a replicated building system using subclassed HISM components.

My brain is slowly turning into ooze.

[indigo quest]

hahahahaahhaah dayum I had to google what that even is

tho much more fundamentally useful for a survival game I'm guessing

[maiden wadi]

Possibly. To be honest it's not so bad. I'm enjoying this much more than doing inventory stuff. I just miss working on gameplay aspects. I'll probably like this much more once I get to the placement system. Right now I'm just working with pure data and replication issues so it's bleh.

[indigo quest]

Yeah I can imagine doing only abstract stuff becomes a drag after a while, I've transitioned to tech art a lil' bit ago so I think there'll be more of that coming my way eventually, albeit not purely.

[white scroll]

Easiest way to get number of certain substring in a string?

[dark crow]

Get Substring?

[white scroll]

It just gets the start index of the found substring. One way ofcourse is to just start the search again from the index and do that till the end but was wondering if there was some ready function for that

[dark crow]

You can modify the starting index or the length after the index

Let's say i wanna just get the first 10 characters
starting index 0 and length 10

I wanna get just the 5th character
starting index 4 and length 1

[white scroll]

I know

[dark crow]

You wanna actually categorize each Char into a number depending on their position in a String?

[shrewd mural]

Is there a way to 'redirect' the outputs of a node? Basically just replace Selected Actor with Selected Character without having to manually re-make all the connections?

[dawn gazelle]

hold ctrl and click and drag the pins

Hello guys, I have problem with my booster item
How does this booster item work? When I get it and press left shift I have faster speed for 5 seconds, but if I stop pressing the button and I press it again, I don't have the boosted speed, how I can do it?

[violet inlet]

hello guys i have a wierd problem with my spline bp, he his showing only in editor and when am out of the player character , the actor is not set to be hidden in game

[rancid topaz]

I know this is stupid but if anyone is willing to do this it would be really nice um is someone willing to be like a teacher to me and half time on whatever day and can teach me how to use unreal

i mean yeah i could look at tutorials but I would like a live class if someones willing to volunteer with that

if not then ill talk to my mom about classes for me

[primal smelt]

Is anybody here well practised / knowledgeable when it comes to ensuring your code is framerate independent? I'm currently running some tests to try and get a vehicle to turn the same amount irrespective of framerate using torque and I could sure use some pointers.

[rancid topaz]

frames dont control the sensitivity on your vehicle

so what you might wanna do is maybe have a value or float for the vehicle steering to be set higher

framerate isnt what controls how a game functions its more of how it visualizes like how well it runs on your monitor

[left niche]

multiplying the delta time with the variables you use is a good way to start

[maiden wadi]

You just have to do everything by a multiplier. Usually delta seconds.

[primal smelt]

It seems to be a bit more complicated than that where physics are concerned, I have substepping enabled and have managed to get the vehicle to turn at a close enough rate by dividng delta seconds from 1 (multiplying does not work here) to get the framerate and then setting that as the maximum float value which increases by 1 each tick. Ideally I would want it to be the same, however. I'm just now about to grab my dinner but all post screenshots when I'm back at my pc.

At 30 and 60 fps the difference is barely noticeable but at 120 fps it falls short when trying to do a 180 turn for example.

[hollow gorge]

I hope this is the right channel to ask: I was trying to create a toggleable auto walk function (going forward, possible steering with mouse). The event is started by a button press (so no event tick start), does anyone know a right approach to keep the required resources to a minimum?

[maiden wadi]

Delta seconds is your multiplier. Take for instance you want you turn 90 degrees over 5 seconds. 90/5 = 18 degrees per second. 18*delta = degrees to turn per tick.

In physics you translate some of that to speeds instead of time. Speed gets multiplied by delta to determine new location or rotation of this tick.

[trail condor]

I'm creating a bunch of buttons in a loop. I'm binding them to an OnClicked event. Is there a way to find out which button triggered the event? Or some way to pass along more info into the event?

[hollow gorge]

@trail condor you could try to get more info by throwing in a few different string messages in between and see which provide feedback

[trail condor]

what do you mean?

[primal smelt]

This is my attempt at dividing 90 by timeline length (0.25) and multiplying that by delta seconds (from the event tick node). I'm using torque in radians as degrees sees virtually no movement at all. I must stress that I don't need it to rotate by 90 degrees as in the final product the amount will be determined by other factors. So long as it is consistent across different framerates.

Doing it this way results in there being quite a large difference in how much it turns when jumping from 30 to 60 to 120 (lower fps = greater rotatioin)

[maiden wadi]

Where is delta being updated from? You can also use get world delta seconds.

I'll be able to help a bit more in a little over an hour. Out of the house, so no ue4 at the moment.

[primal smelt]

This pile of spaghetti is taking a different approach and so far comes the closest to getting the amount of rotation to match regardless of your current framerate. Between 30 and 60 the difference is not so noticeable but going from 60 to 120 and while still not too bad it is certainly noticeable.

When the player fires off the instruction to add torque the LHandTorqueAdd event is called and adds 1 each frame until it hits the max float value dictated by the >= node. This node is 1/Delta seconds as this gives me the framerate. Even though going from 30 to 60 is doubling the number of ticks a torque force is applied, it still works out to fully rotate by a similar amount. I'm not sure why this is, perhaps because this is an actor with phys constraints for wheels as well as gravity enabled that there is some kind of interpolation going on between each frame?

Funnily enough I just tested it again and if anything 30 is undershooting it a bit whereas earlier it seemed like it was doing that at 120. I must have tinkered something and forgotten. But really I'm just after a bit of guidance - any drawbacks to doing it this way? Any comments about how I have attempted the delta seconds method you suggested?

[primal smelt]

That's very kind of you thanks! I'll still be online for a good many hours as yet so would very much appreciate any help.

And the event tick delta is being set from event tick. I'll try getting world delta seconds now

[maiden wadi]

Out of curiosity, why not axis events?

[primal smelt]

Getting world delta seconds seems to give the same results

[primal smelt]

The vehicle I'm making is a wheelchair and instead of holding a button to accelerate you "push" either left or right wheel, so it's just a single fire event

[maiden wadi]

Ah, that makes sense.

[primal smelt]

The left wheel forward adds positive torque and the right wheel forward adds negative torque (and if you push both at once - this may be inefficient - both forces still paply but counterbalance to keep the vehiclemoving straight forward)

*still apply

[signal heath]

I have a question regarding blueprint logic and structure for a high level overview of a kart racing game:

Here's my thought process on the same-----
Create an actor BP for wheels

Create another actor BP for the whole cart

The wheels BP is a child of the Cart

Create variables for acceleration, velocity, friction, weight etc and apply them the wheels BP for applying a change to the transform's rotation and to the cart and then creating a function that would affect the wheel BP based on the value of weight

Finally, create a BP class for abilities

This class is spawned on a timer on the race track or based on a powerup like a 'random power' ability

Depending on if the game is made to have abilities inherently for the karts, the ability would instead be created as a function

---

Is this appropriate? What would you add/edit or how would you go about planning to create such a game, from a high level, making use of technical blueprint terminology?

[maiden wadi]

I don't fully understand why your time line doesn't work. The math on it looks fine... At 60 fps that should add about 6 torque, at 30fps about 12.

Should do that per tick, or per time line update.

[primal smelt]

Yeah I thought maybe substepping was the culprit but disabling that doesn't seem to yield any different results unfortunately. Perhaps it has something to do with the way I have the physics constraints setup for the wheels? I wouldn't know what to start checking though!

[primal smelt]

The other method of running it on tick with the delta providing maximum number of frames to apply torque, I'm surprised how well it is working now. My biggest concern doing it that way is what would happen if the framerate dipped while that event is running?

[maiden wadi]

One person that I know could definitely help hangs out in #legacy-physics. I can do some tests, but @atomic salmon is the guy to ask about physics.

[primal smelt]

Great, I'll see if I can get his attention! I'm sure the method you suggested would work fine if I was rotating the actor instead of applying torque, I will give that a try in a moment. Problem is I can see that causing problems with how I've got things currently set up what with how the counterbalance of torque works to keep the vehicle moving straight.

[indigo quest]

Yo, I don't think I quite understood the find closest point on segment part, could you please elaborate or correct me a bit more?

I can't debug why my bones seem to teleport away

and why it bends 90 degrees at the end like that, like theres some pivot there, all the bones are directly parented to the root

[marsh seal]

is this a good place to ask about sound occlusion?
im setting up a 2k map with some buildings that have interiors
i dragged in the sound of nature and despatialized it just so no matter where you go you hear it and its not like "coming from over there!"
but... is there a way i can occlude a sound thats not spatialized? OR.. are there some attenuation settings that i can use to De-stereo a sound even if its spatialized

[maiden wadi]

@indigo quest I'm uncertain about the bone issue. The math was more or less a SphereTrace. You specify a start and end location in world space. And for each bone it finds the closest point on that line to the bone. If the distance between that found point and the bone is within the radius, then it can be considered hit by the trace.

[long smelt]

I wonder if UISound can be used with spatialization @marsh seal

[maiden wadi]

@signal heath The simplest way I could think of to implement that, would actually be to make the kart an actor. The wheels would be components attached at sockets or locations on the kart. Wheels can be made to behave however you want based on their owner actor. As for power ups. Those could be a mix of events or actor components. Simpler ones could be simple events in the kart that a powerup actor could trigger. More complex ones can be an actor component that a powerup actor could make the kart add to itself to affect it for a time.

[mellow folio]

I know I’ve used code before to manually check whether we are inside and crossfade sounds. This can be useful in other areas too. Just put overlap volumes in your buildings or for an even more expensive approach, regularly line trace

I once lerped between wind and howling wind based on how surrounded the player was by collision. This caused a howling sound when the player was in a crevice

[indigo quest]

Thanks for your help, I'll continue digging around

[maiden wadi]

I unfortunately don't do physics stuff enough. Unreliable in multiplayer environments.

[primal smelt]

Looks like Add Torque operates on tick which must be why the math seemed correct but the results weren't expected!

I'm trying to debug the water caustics generator blueprint in the unreal editor. I've put a breakpoint in the blueprint that should hit when I press the 'Begin Rendering' button but it never hits. Is this a limitation of blueprints that run in the editor?

[teal lantern]

The ball moves with the mouse. How would I make the sword always point an the ball? I tried look at but it doesn't rotate so that the point is touching the ball.

[polar fulcrum]

Look At should work. Seems your aim vector should be the Sword Z axis. and the rotate vector the Y axis.
You could also skin the sword with 2 joints, one at the pivot rotation and another at the sword end, and use an IK system (Anim Blueprint post process) to move the top sword joint ant automatically rotate the base root joint (disclaimer, I have never done an IK to a root joint so it might not be allowed, in that case you will need 3 joints, the root, the one located at the sword handle and the top one).

[teal lantern]

Look at has Start and Target as inputs. is the aim vector the start and the rotate vector the target? Is that what you meant?

[keen wedge]

Hi all, don't suppose anyone can think of a reason why the load of a save game object wouldn't work after a build (as a standalone/windows) but does in the editor?

[maiden wadi]

Depends on the build type. Did you save in the editor, and then build and try to load it in the packaged build?

[keen wedge]

hiya... actually tried a combination.... in editor only, both saving and loading works fine. Then I created a build, ran it, it saves the file, but doesn't load it again. The file is there. Can't think why this would be a problem.

Was running it from my desktop, moved it all to a separate drive and ran it from there, still no joy.

[maiden wadi]

Hmm. I can't say I've had that problem. I know that shipping build games actually save to Appdata rather than the game or project directory.

[keen wedge]

Whats REALLY annoying is that I think I have had this problem before and I can't remember what I did to resolve it. I have another game that I made and that runs fine saving and loading... so annoyig..

[maiden wadi]

You're not checking it though. You're checking if the pawn is valid. But that pawn has a struct with another pointer in it that points to something else that isn't valid and you're calling AssignEmployeeJob on that.

[timber pilot]

Ahhhhh that makes sense

[static charm]

authaer, what do u do for a living

[maiden wadi]

Exist mostly. Haha. Why?

[keen wedge]

I think its going to be another of these, what gets built first issues... ffs... does my head in ... guessing now there's a difference in order between gamemode and level being created first...

its like the other day, all over again.

[maiden wadi]

A lot of it's just very fresh. It's a hobby I've been working on for the last year and.. some months now.

@keen wedge Hmm. Still shouldn't affect loading though. Or is it a logical issue after loading?

[keen wedge]

Its triggering this Print at the moment...

Thats in the level blueprint...

looks like the level and gm load in different orders

depending whether its in editor or standalone

[maiden wadi]

Are both of these running on beginplay?

[hollow gorge]

Hello, I'm currently trying to change my 3rd Person Camera in a way, that allows for free Character movement without the direction of the camera influencing the character's path when moving. Any ideas?

[keen wedge]

😩

I hate myself...

(but Unreal Engine more)

[maiden wadi]

Haha. Generally, don't ever trust beginplay's order. Alternatively, you can just load up the savegame from anywhere and get the data from it and then let it be garbage collected instead of saving a pointer to it. So GameMode can load it, get the data it needs, do it's stuff, and then level can come along, load it, get the data it needs and do it's stuff. The only time this isn't preferred, is if you have a stupid amount of data. But then you should consider multiple different save files for different things.

[keen wedge]

Whats really bizarre about all this ordering nonsense though is that this is about the 5th noddy little project I've made using UE4, and this is the only one I think I've had these problems with. Its frustrating because the code to do the actually functional does work, it does save, it does load, I have a little admin screen that displays it.. all lovely... but then you build and its like, oh ffs... here we go again... will maybe trying bumping the loading into the game instance... that gets created first I think, so maybe that'll work. dunno. so tired of this 😦

[flat raft]

Hey hey.. I have a question, but I don't know what the effect/control is called...

In metal gear 5, when snake is crawling on the floor, or when Tomb Raider is squeezing between rocks, or in order 1886, when you're escaping the prison...

What's the cinematic control effect called?

The player can only press forward, but it plays the squeeze through wall animation

[nova rivet]

Camera control?

[white field]

can any Actor have PawnSensing component and actually work, or does it need to be of Parent class Pawn or something?

or is there some other trick to having pawn sensing work on child actors?

[spark steppe]

technically you would play an animation where the player controls the animation position with w/s key

if he reached the start or end of the animation you would return to normal input

[flat raft]

Is there a specific name for that?

Like the button pushing during a cinematic is called QuickTime

[bright frigate]

Is there a easy way to figure out where this is being fired from>? Blueprint Interface Event,

Does this not work anymore?

Following this I can't get it to work. I have a lightswitch, and I want it to toggle visibility on a pointlight inside a seperate light blueprint.

[dawn gazelle]

All this is really showing is changing a boolean variable between two blueprints and yes, this way still functions. Are you getting any errors or anything?

[royal helm]

I'm a bit idiot, and I figured it out myself. I was getting missing reference errors. I had to select the correct reference in the details panel

I'm still learning, so forgive me. ❤️

[left cradle]

How can I assign a int/float value to Cam1 (actor refrence) in level Blueprint ?
I will be adding it in Event Begin Play.

[barren flower]

@left cradle what exactly do you mean? If it's an actor you can cast to it.

[left cradle]

@barren flower So what I mean is, I want to set value to cam1 as int/float so that i can switch multiple cams by just comparing values with cams.

[barren flower]

You aren't making sense. Set value? What value?

Do you mean you want to give each camera some kind of ID number?

[left cradle]

Yes

[dawn gazelle]

Use a map variable.

[barren flower]

Yeah that's the best way

[dawn gazelle]

Alternatively, you could use an array, but it's easier to keep track with a map.

[barren flower]

Give the camera actor an int variable called 'ID' or something, and click the eye next to it in the variables panel to expose it to the editor.

Give each camera a unique number, and have them cast back to whatever is switching and add themselves to the map array with that as their key.

That allows you to dynamically add them, too, if the each check the map length and add 1 as their own id

Actually if you let it be dynamic like that they don't even need to contain their own variable, let the map address them on its own.

[left cradle]

Cool, Thank You guys. Will try this way 🙂

[barren flower]

Alright my question now.

Anyone have ideas on how to approach an npc dialogue system? I want two NPCs that approach eachother to be able to have a short discussion with eachother, and walk away.

Kind of like the system oblivion tried out.

But it has to be interruptible, so if they are attacked or something they can bail on the conversation and respond.

Any ideas? I don't even know how to APPROACH this

https://youtu.be/odkmx8sDi1o

[left cradle]

Am a newbie, I dunno much but try this one tutorial. https://www.youtube.com/watch?v=3uW7CgmrKAo

[flat raft]

Try Ai behavior tree

[barren flower]

I haven't done much with the tree, but I'll look into it. My question though is how on earth do I pass the different messages between eachother? Some conversations will be different lengths than others, and each pawn needs to pull its own lines from its personal voice type too

They need to know to wait, for how long till the other pawns line gets delivered, and then pick an appropriate response to that type of topic

[dawn gazelle]

You probably want more generic lines than anything. Basically, have topics that you assign to an NPC that they want to talk about. Then have the other NPC respond with generic, non-specific banter.

You can have the NPCs test if they want to talk to each other (perhaps a random roll on both) and if they do, toggle a boolean on in both of them to indicate they're talking to one another. If you're wanting to wait for actual spoken voice lines to finish playing, you can bind events to when the playback stops.

[flat raft]

Use a Datatable to list all the dialogue. Tag them to a topic. When the Npc meet they will choose a topic, and assign each other the lines

[dawn gazelle]

If two NPCs happen to have the same topics assigned, then the responding NPC could respond a little less generically.

[flat raft]

as for when to talk.. in the datatable you can also set a wait time.

Weather :
1-1 : Hi : 2sec
2-1: Nice Weather : 4sec
1-2: Indeed : 2sec
2-1: bye : 1sec

There are a lot of dialogue stuff on the youtubes

[barren flower]

Hmm okay it's a direction to explore for sure, thanks guys

Also @flat raft i love stargate at that is horrifying haha

[flat raft]

lol

[barren flower]

This is the real reason the replicatiors won't stop

[white scroll]

Is there any way to switch between directx 11 and 12 without restarting the gamme?

[barren flower]

That's a fundamental library of graphics instructions to the graphics card, on how to do all low level graphics processing.

I would bet my house against being able to switch that on the fly, and you would be stupid to even try, for stability reasons

[white scroll]

K, thanks

[grim heart]

Hi! I'm controlling a level sequencer from a blueprint.. it works perfectly when the level sequence is open in the editor (in sequencer tab) and I play the game ... otherwise nothing! I'm so confused... would appreciate any suggestions!

[sonic frost]

Does anyone know how I can get around this infinite loop? I just want my Blueprint to keep running after B is pressed and stop when B is pressed again

[junior mural]

try using gates

[faint pasture]

what do you mean by keep running, do something every frame?

[sonic frost]

@faint pasture Yeah, I ditched the while loop for a Tick event which has been working better

[faint pasture]

Yeah just on tick, branch on bIsBuildModeOn

then when you press the button, set bIsBuildModeOn = NOT(bIsBuildModeOn)

[barren flower]

GUYS

for real

@sonic frost Use a flip-flop node

and use a timer

@faint pasture dont ever use tick, theres no excuse for it, not even for beginners

https://youtu.be/DtOlHXZN-1w?t=26

[slender idol]

What is the best way to make an actor using RotatingMovement push the Player away when hitting hit?

[teal dove]

@slender idol Turn on physics on the Player ... actually you just need to have a collision turned on the rotating actor, it should automatically push the player away.

[teal dove]

Yeah this

Use Timer By Event instead of tick

[slender idol]

@teal dove the collisions work fine, the rotating object doesn't seem to push the player just preventing him from clipping into the mesh.

[earnest urchin]

if I make a change to a base character at run time, say increasing the base character's health variable, will that apply to all child characters as well?

Specifically if I do it during gameplay

[maiden wadi]

Lolol I love that video about tick. He's concerned about a few math equations on tick.

[teal dove]

@earnest urchin No, you need to call all other actors / characters as well to tell them to change the variable. Unless you use an event system that propagates the change to all event receivers.

[glacial eagle]

Tick is fine btw

[teal dove]

@glacial eagle That heavily depends on the case, it's almost always better not to use them

[glacial eagle]

The only thing you want to avoid is doing heavy math/container work on tick - and even then most of that cost is the Blueprint VM not the math work itself. If an actor is already ticking for some other reason, there's very little reason not to use it.

But the notion that tick is inherently bad for performance is plain wrong

[mellow folio]

what do you mean by "child character".....

because that could mean child class or child actor

[maiden wadi]

Timers can be worse than tick in some cases actually. If you set your timer to 30 times a second to avoid it being called 60 times a second on a better machine, then the machine that only runs at 20 times per second will have 10 frames that do double the work, because the timer will run the function twice every other frame.

[teal dove]

@maiden wadi this is incorrect, timers are time dependend not frame dependend

event ticks are actually framerate dependend

I stand corrected

however it remains true that event ticks are framerate dependend

[glacial eagle]

everything is framerate dependent

Timers "tick" internally via a manager

Timers can be just as deadly

[faint pasture]

tick is fine if something needs to update every frame.

[glacial eagle]

The answer is as always: profile it 😄

[teal dove]

Yeah this 😄

[glacial eagle]

But just be aware that timers aren't a fix-it solution, and can even create more issues if you don't use them properly

[round basin]

Hi, do you know why my framerate settings doesn't apply in the editor (I recently disabled plugins like chaos)

[teal dove]

Movement Input is a good example for something you want to tick, especially in an FPS (axis input is already ticket in blueprints)

[glacial eagle]

If you have a timer set to 0.01 seconds, and your game runs at 60 for example, your timer is being called more than once each frame very often

Since timers will 'queue up'

So you can actually make things worse

[maiden wadi]

@teal dove Small example.

[glacial eagle]

Just avoid simulating the universe each tick and you'll be fine

[faint pasture]

I run 1500 line traces on tick at over 100 fps, you guys will be fine with whatever you're doing lol. Heavy math in BP is what eats up time, otherwise don't worry about it.

[maiden wadi]

Timer still runs 30 times a second. So you're still wasting ten frames a second on slower machines.

[faint pasture]

Timer is dumb for things near framerate anyway. It's alright for things in the 0.1+ second range tho

[glacial eagle]

#cpp has descended on #blueprint 😄

[wind sequoia]

[slender idol]

Is there any correct way to make Characters be able to be pushed around? Whenever my character stands still and gets hit by a moving obstacle, the character just jitters around the obstacle and isn't actually pushed by it.

[keen bluff]

does anyone know why this isn't working? Is it bc I've set inputs in my C++ class?

it's just in my character class

thirdperson

[maiden wadi]

Blueprint should override C++ bindings. The only reason that shouldn't work is if you have an E binding in something else that is consuming the input before it reaches the character.

[keen bluff]

oh

i'll try anything else then, not sure if i do

omg it's working hahaa

I did a stupid

thank you !

[maiden wadi]

Is this in a widget binding?

Is the widget added before the weapon is spawned?

If it works, I'd assume the widget is being created before the pointer is valid. Just a small side note. Setting a brush like this every tick is a bit expensive. You could created a binding to call whenever you change equipped weapons and have your widget bind an event to that, and only update the brush when the weapon is changed.

Softrefs are also good here to avoid loading too many assets at once. UImage has a great function for setting the brush from a softref UTexture2D

Uncertain on that one. The bindings should all tick at the same time more or less. So three different bindings getting the same thing should all return null.

[neat prairie]

is there a way to get the rgb colour of a material and use it in the blueprint for a separate material?

[rancid topaz]

somethings you use a node that can change the rgb

if you have a node which allows u to pick your material

and it says like rgb or whatever then you should be able to change it yeah

yeah

but that depends cause sometimes the person already has the material set to whatever it is and dont wanna change the parameter of it so instead they use something that isnt like draw rect or whatever that other node is where u select the material

[neat prairie]

@trim matrix well i found the GetMaterialAttributes node and you can output the baseColor value, but it requires a material input

nevermind, it is material functions, i will check them out

Hi, I have an issue with CharacterMovement. The vertical pillars move using RotatingMovement around their own axis, is there any way I can make them push the Player that uses CharacterMovement around? I tried using launch character, set velocity on hit but it is very inconsistent, the character keeps jittering around the pillar.

[trim matrix]

Use physics

They should push your character automatically

[left niche]

Don't use get all actors of tag. thats the issue here

[slender idol]

@trim matrix that just makes the character unmovable by the object using physics. no matter the mass settings I use the object is always stopped completely by the character

[flint trench]

hey all, trying to make a turn based strat, whats the best way of storing the players units' stats?
atm i have them stored in an array of structs in the instance, but i cant figure out how to get the units to access without a direct call to the right place in the array.

the units are placed by the player so when spawned I can't expose a pin to plug the struct into

[teal dove]

@slender idol Do your pillars have collision properly set up? Also does your Player character have physics enabled?

[slender idol]

@teal dove I have box collisions taking care of the collision itself, I don't think I am able to enable physics for the character since that will disable movement.

[teal dove]

You mean the Player Character or the Pawn? The former can have movement with physics enabled

both can actually

[slender idol]

well physics for the pawn itself (capsule component) is disabled

and I use kinematic movement for the charactermovement itself

meaning I don't move with add torque or impulse or force etc

[teal dove]

Do you use the character movement component?

[slender idol]

yes

I use its movement functions

[teal dove]

Try to enable physics on the character mesh

I have to leave now, but I will be back in about an hour, if it's still not working then I can help you figure it out.

Hi friends.
I have a float in an animation blueprint that goes from 1 to 0 immediately and i'd like it to have a smooth transition. Can anyone help? i dont really know how to approach this

[rancid topaz]

@small plover u would need to use a timeline

its like a keyframe when it comes to video editing if you know what i mean

it allows u to configure the line that goes from point a to point b depending on how fast you want it to happen

[small plover]

is it usable in animation blueprint? i dont see it when i try to find the node

[rancid topaz]

in an animation blueprint i dont know

but when its a character blueprint you can connect play animation

to a timeline

[subtle nova]

I'm trying to set up a very basic quest system. But with level streaming it's becoming a headache. Does anyone know of a good way to implement a simple quest system with levels that can load in and out? Things need to reference each other, and subscribe to events and such, but they they load/unload and those references are broken.

[rancid topaz]

i dont know im pretty new but i believe its something with a timeline Nirva

no it isnt. lerp

[small plover]

it seems it cant be used in animbp

[rancid topaz]

oof

well i dont know anymore im sorry 😅

it looks promising but how do i use it? i need the last value so i have to store it somewhere is that it?

And if so, can it be done all in animbp?

Hi guys, I'm having bad performance using WidgetBlueprint or TextRender component. My scenario is pretty simple ... I want to show multiple dice (cube mesh) with a number on every faces of the cube.

I guess, another solution would be a material applied on every faces of the mesh ... but I do not have the knowledge to create such a material ... anyone wanna help ? 🙂

[sand pine]

Hey guys, quick noobie question, I have an imported modeled actor, using a linetrace for hitscan, when I drop the actor in through drag and drop the line trace hits it no problem, however when the actor is spawned in through means of a trigger box, the linetrace no longer hits them. Any quick ideas what could be causing this? Any help would be appreciated, thank you!

[teal dove]

@sand pine You have to be more specific: who is firing the linetrace and what is getting hit?

[ornate bison]

there is 1300 objects, how should i call them?

[sand pine]

FirstPersonCharacter (Base BluePrint aside from slight moderations) is firing, and the imported actor is (attempting to be) hit

[teal dove]

When are you firing the linetrace? It could be that it's firing before the actor is spawned.

If you know it's firing the linetrace after the actor is spawned, then check if the actor is spawned with correct collision

[sand pine]

I have the actor spawning and running at the player currently, and the player fires a gun, I have checked collision and overlap all, on every aspect of the actor and any blueprint that I can think of that may have something to do with it

Currently have run out of ideas 😅

[teal dove]

So if you drop the actor manually, the linetrace registers a hit, but when it's spawned via blueprint, the linetrace does not generate a hit?

[sand pine]

Correct.

[teal dove]

hmm can you screenshot the blueprint part how you spawn the actor?

[sand pine]

Absolutely one moment.

[teal dove]

take your time 🙂

[sand pine]

Thank you so much for taking yours to help me

[teal dove]

no problem, I hope we can figure this out ^^

[left niche]

1300 😕

[supple plank]

hmm, it only let's me make the character jump now but not move it to left or right. Do you know a way around this?

[teal dove]

@ornate bison 1300 is wayyy to much to get this way. I would implement a method that changes them based on distance to the camera, like an overlap volume around the player, and it changes those close into instanced meshes.

[sand pine]

This is how they are set to spawn (currently in the level blueprint)

And this is the setting within the "Base Zombie" Class that it is spawning from

[teal dove]

@sand pine Hmm if you use "spawn actor from class" instead, do you still get the same problem?

[sand pine]

Rather than the "Spawn AIFrom class"? Just to clarify what I am editing?

[teal dove]

@sand pine Yes instead of the spawn AI from class

[supple plank]

This is how i made it now but when i try to move left and right it also seems to be affected by the time which holds the velocity at one

should i turn back the dilation at my input blueprint?

I'll test it

[sand pine]

It does appear that the problem persists. Doing some further edits to make sure but on initial edit the problem remains.

[left niche]

Instanced mesh spawned along a spline. How to get the vector away from the spline(so i can set the offset for things like balconies/fire escapes towards or away from the wall).

[teal dove]

@sand pine In that case, try to set your "Update Overlap Method" to always update and see if that helps

[sand pine]

No dice

[teal dove]

puhhh 😛

[sand pine]

Yeah this has been killing me

[teal dove]

Did you check the log for what it says when you fire the linetrace?

[sand pine]

Can I bring it up while in simulation/play? Not sure how to do that if so

[teal dove]

It should record it and you can check it afterwards

[sand pine]

Sorry for the ignorance here, but where do I find the log? Usually the only time I see it is when it pops up after an error when I exit simulation. But currently I am not having any errors

[teal dove]

Go to Window --> developer tools --> output log

Though I am not sure if it actually logs the hitscan there

[sand pine]

When the gun blueprint fires the linetrace, it does mention the gun blueprint, and the component hit by the linetrace. It appears to go right through the "zombie"

I also have it set to print whatever component the linetrace hits when simulating so I can see while playing it if it hits the "zombie" so I would know if it hits anything

[teal dove]

I can only guess that it does not properly enable the collision when being spawned, which is weird but I had problems with AI spawned via blueprint myself

It's hard to figure it out on my end here though 🙂 if you want you can pm me and we can screenshare

[sand pine]

If you'd be willing I would absolutely do that

[teal dove]

sure pm me

[supple plank]

Is there a way to 'slide' the value of a float over a certain amount of time? I'd like to slide a variable from 0 to 1 in about 0,3 seconds and vice versa

[prisma stag]

You could use a timeline.

[supple plank]

Could you expand? i'm very new to bluaprinting

[prisma stag]

In your event graph you can right click and select create new timeline. .

When you double click that, in the top left of the grey window, there should be this

This will create a float track.

Once you select that, on the top it says length, think of that as you time.

Then, on the graph for the track, shift + left click to add 2 nodes. When you select a node a Time and a Value appear.

[supple plank]

Alright, and i can use this to continuously update a variable?

[prisma stag]

Well you see, when you go back the event graph, on the right of the timeline, the float you added will be there.

You could then, take that float and set whatever variable you want set to that value, and the execution wire would come off of update.

[supple plank]

alright, but i guess this couldnt be attached to a tick event? cause it would keep starting from 0

Thank you very much btw!

[prisma stag]

When timelines execute, their value is saved at the time they stop. This in itself doesnt need a tick event setup since it will always update.

np.

[supple plank]

Yeah the problem is i need it to link up with a tick

[prisma stag]

I see.

If its something that will happen right as the level start you could just have it connected to BeginPlay.

[supple plank]

Can i dm you?

[prisma stag]

Sure.

[trim matrix]

hey guys, any workflow ideas for hunger impacting walk speed swing speed stamina regen etc? including buffs

id try to maths but im bad at maths, so would using datatables work?

get like 3 datatables? starving hungry full etc?

[dawn gazelle]

When using pure nodes, like the "Random Integer in Range" you have there, each time a number is pulled from it, you'll get a new random number generated. Instead, promote it to a variable if you intend to use the generated number more than once.

[trim matrix]

put the variables in there?

[dawn gazelle]

Also, if you have an actor list, the actors themselves should have whether they are male or female defined on them.

[prisma stag]

Quick question: The origin of my actor is at the middle of it however I would like it to be the bottom middle. If I add a scene component and set it as a root, will it be placed at the scene component if I do set actor?

Hello guys, I have problem with my booster item
How does this booster item work? When I get it and press left shift I have faster speed for 5 seconds, but if I stop pressing the button and I press it again, I don't have the boosted speed, how I can do it?

this is the code for the custom event that boost the speed

with this check is again the same result

[trim matrix]

aha

you make sure I need to make it on left shift

cus the boost speed is custom event in inventory player character?

[dawn gazelle]

It can be on any button, doesn't matter. I put it there just to indicate that something should happen on pressed & released of a button.

[trim matrix]

okay

cus I want to make it work if I am with left shift pressed or not

[dawn gazelle]

Then why have this part at all?

[trim matrix]

I want to check if I press left shift or not

I tried to combine the both of the,

like pressed and not pressed

but idk how to do it

I will try now with your way

[dawn gazelle]

Ok, so basically, you want shift to trigger the consumption of the item and give you the speed boost, but holding of shift shouldn't matter, the player will retain the speed?

[trim matrix]

this booster item is, you get it and have boosted speed for 5 secnds

but I want to make it to work,doesn't matter if you press left shift or not

[dawn gazelle]

So shift has absolutely 0 value in this at all then?

[trim matrix]

yep

so I have left shift for running animation, but when it is connecteed with this item, it doesn't have any value

[trim matrix]

I understood this code

but I don't think i need to do it there cus every time I press left shift I will ave boosted speed for 5 seconds?

[supple plank]

Is it possible for an actor to have it's own time dilation? (That is not a multiple of the global time dilation)

[dawn gazelle]

This would probably make more sense.

[trim matrix]

wow

okay

[dawn gazelle]

Basically.... Any time you pick up a boost item, it'll reset the timer back to 5 seconds.

[trim matrix]

yep

but what abotut the left ahift?

[dawn gazelle]

Left shift shouldn't matter as you said.

[trim matrix]

I want to have boosted speed, doesn't matter if I hold or not left shift

[trim matrix]

okay

[dawn gazelle]

If you're changing player speeds on your shift key, then you should do a check to see if "Is Speed Boosted" is set false, and only then allow the shift key to augment the max walk speed.

[trim matrix]

aha

okay

I did your code

I have this code for left shift

[trim matrix]

aaaaaaaaa

😄

the defaul value of speedboosted is false

now I go through the item and don't get it, lmao

[dawn gazelle]

This would only allow your shift key to modify the speed if the player is not currently speed boosted.

Effectively a speed boost will force your player to move at 800, regardless if shift is pressed or not.

Once the timer wears off, then your player will go back to their normal movement speed. If shift is pressed, then they'll be able to go at their "running" speed or whatever you want to call it, but only so long as they aren't currently speed boosted.

[trim matrix]

yep

this is how I want to work

but

[trim matrix]

.

[dawn gazelle]

has nothing to do with anything we've been working with.

[round basin]

Hi, how can I call an event that is in a child actor, when I am in my "main" actor ? please

[trim matrix]

aha

okay

hmm

[dawn gazelle]

Get the function/event node you're looking for then set your child actor reference as the target.

[trim matrix]

so in my booster item which event I need to get in touch with?

boost speed event

or boost event end?

this is the code and stil can't get the item, hmm

[round basin]

@dawn gazelle Is that what you meant ?

[trim matrix]

yep, the problem is from the event

I removed it and I can get the item

hmm

Do console commands entered in BP have effect on a packaged game?

[dawn gazelle]

Sort of. Do you have a component with the name "PIece" in the top left, around here? Or is it dynamically added?

[round basin]

I don't, it is just a child actor

[trim matrix]

do I need to put the boostspeedevent and after it boostevent end?

[dawn gazelle]

Ok, then I believe you'll need to cast the child actor reference to Piece in order to run that event.

[winter seal]

This what u were talking about Datura? My problem with adding "isMale" to my list is that the list is skeletal meshs and have yet to figure out how to make a list of "characters"

[round basin]

Yes but if the event is supposed to change things to the actor itself, would it work ?

[dawn gazelle]

Yes

[round basin]

Okay, i'll try that

[trim matrix]

these are the collusion settings that I have

[dawn gazelle]

When casting, you're trying to get to the specified class type of the object you're referencing. So if your Child Actor reference is actually referencing an object that is of the class "Piece" then the cast will succeed, and your object reference can have access to any functions or events that Piece classed objects have.

[round basin]

uhh

[dawn gazelle]

Whats the warning say?

[round basin]

"'Piece' does not inherit from 'Child Actor Component' ( Cast To piece would always fail)."

[dawn gazelle]

Gotta do this it seems

[round basin]

It works! Thanks a lot!!

[trim matrix]

how to fix the collusion problem?

unfortunatelly still can't get the item

[dawn gazelle]

Yes, that's better for the random number. This part is no good right now though, as the integer should always be > 0

[trim matrix]

yep

I put breakpoint on casting to the player

and it showed me it

when I clicked on step into

and it stopped

[dawn gazelle]

I believe so. The console is still available in packaged games, so I would imagine a BP initiated console command would function as well.

[trim matrix]

ok

another problem in my other project which is runner game
for now I am switching the lines with the "arrows", now I want the player to be able to do it with the A and D keys too
I connected the code for the same binds and the D works, but the A not

[hushed pewter]

Ok using a tick with a lerp is fucking stinky

Anyone know how too use lerps too create keyframe like animation ;;/

[trim matrix]

use timeline

[trim matrix]

it works but I do the smae code for the key A and doesn't work as the key D

[quasi frost]

Is there someway to set a max follow distance for AI MoveTo?

[mental sail]

You could use Acceptable Radius, the very first variable on the node

(if you mean, follow and stop before reaching the target location. Otherwise, if you mean follow target location that is moving, but then stop after a certain distance from original position, you'd have to make some extra logic)

[quasi frost]

The second thing is what I mean

[mental sail]

I'd make a decorator, attach it to Move To and make it check distance of character to original position and return success once distance has been reached.

There is also a "Time Limit" decorator that you could use to have a similar effect but based on time not distance

Question about Controller blueprint variable reading in Animation Blueprint, vs Character variable reading... the setup: I have a FABRIK node that checks for a boolean before doing something on my character (moving a hand into position) I've attached the boolean through the animation blueprint pin drop-down/selector. The issue is: if the variable is read from the AI Controller BP, it does not update the animation (acts like it is not set, even if it is) But if it is linked to the Character blueprint boolean, it works as expected. I know that the Controller AI does have this boolean value properly set because I use the Character Blueprint to read this boolean and set it's own boolean based on this value... So, I guess, the question is, why the different behaviors when reading value from Character blueprint vs Controller blueprint if value of variables is identical?

[quasi frost]

Hmm, do you think it would be more optimized to just have an enemy "area" volume and when an AI stops overlapping with the volume it runs back to its starting position?

[mental sail]

Certainly a way to do it as well

If your game allows for that kind of setup, another way is to use a limited Nav Mesh Bounds volume to a similar effect

With your idea, you could then use the "Blackboard based condition" and have a blackboard variable updated on the event the AI leaves the volume trigger that you set

[mystic storm]

I am appalled

How does it make any sense to rotate an asset without rotating the collision

How does this happen

[dawn gazelle]

Rotate the actor rather than rotating the mesh?

[mystic storm]

I don't think I have an actor to rotate

I created those with add component

[mental sail]

The two are separate things, there's no reason why two separate things should have the same rotation. If you do want than, then either add the collider as a child of the component, or the component as a child of the collider, or have a parent "Scene" component that holds both, and rotate that

[mental sail]

Is that the mesh collider?

[mystic storm]

I've downloaded ue4 today, I wouldn't know how to answer that question

basically, I used blueprints to procedurally generate hexagons in rings using cube coordinates

but the model I used wasn't in the orientation I wanted

which would completely mess up the math for converting hex coords to actual coords

so I just used a transform to flip it 90 degrees

but when I did that it only flipped the mesh, and apparently didn't flip the hitbox

Can I just rotate the collider somehow?

blueprint or otherwise?

WAIT A MINUTE

I have been bamboozled

THAT IS NOT A HEXAGON AT ALL

THAT'S AN OCTOGON

Wow

I feel betrayed

[earnest tangle]

That's not an octagon either lol

Oh sorry it is, I was being confused by the lines of the collision box :P

[mystic storm]

wait no, the complex collision is a normal hexagon, what am I dealing with here

as far as I know a octagon has more sides than a hexagon

[earnest tangle]

it has 6 edges on the mesh and 8 on the collision mesh

[mystic storm]

how is it more complex

[earnest tangle]

hexagon is 6 edges octa is 8

[mystic storm]

yes, the complex collision is the hexagon, the actual shape of the bloody thing

[earnest tangle]

yes it has 6 edges, making it a hexagon

[mystic storm]

I know it's a hexagon mate, I've been looking at hexagons for hours doing math and shit to try and get this thing to wrok

point is, why is the collision an octagon and how do I force it to use the proper complex collision

even though the "complex collision" is less complex than the simple collision that is inaccurate for the sake of being inaccurate

[trim matrix]

Simple collision is an approximation

[jaunty stirrup]

Can someone give me the nodes for making a mesh exaclty face the camera plz?

I try everything and the result is not well.

[mystic storm]

I used the auto convex whatever the hell to sort of fix it

[mental sail]

Delete it and create it again, it's some buggy stuff from previous settup

Especially if you changed the type of variable from something else before

ya

[prisma stag]

Hello, I have this function that displays a "hologram" to where the object will be placed, however I would like to add the option to rotate the object as well however since this is in a function the Action event I made cant be called. How else could I do this?

[odd roost]

Anyone have experience with Smart Links? It seems that AI will still traverse them even if they are disabled AND an AI standing on a smart link think that then becomes active makes the AI just stand there for the rest of his little digital life

Why cant the event be called?

[pine trellis]

is there any way to add another array to a for each loop?

[dawn gazelle]

Does the second array contain the same type of objects?

[pine trellis]

@dawn gazelle no its another kind of character

[dawn gazelle]

Do they both inherit from the same parent class?

[odd roost]

create an actor array and add them together

[dawn gazelle]

That's kind of what I was getting at 😛

[pine trellis]

ah ok i will try this

thanks

[odd roost]

yw, Just be mindful about how you're using the array. You may need to clear it often.

This is specifically how you add two arrays together

[pastel garnet]

Hello! I am replicating a shotgun/rocket jump mechanic into my game but the force applies to everyone around its radius (Multiplayer)

Any way to tick it so that it only works for a certain player?

[pine trellis]

@odd roost that only works if they have the same object type I have 2 difference character classes

@odd roost isnt that get all actors of class an expensive node to be using for each loop?

[odd roost]

Make the array and Actor array

It all depends on how big your game is and many actors you have

[pine trellis]

its going to be for NPCs....

so there will be alot

[odd roost]

You don't have to use get all actors of class, that is what I'm doing to add them to my array because I need to ignore them and can be added and removed from game during play

Any actor should be able to be added to a generic actor array

Here is another example where I'm finding all of the AI that are currently alive in my game. These are humans, animals, enemies, etc

There are usually around 150 alive at a time and in none of the alpha builds has there been any frame drops when this runs

[white lynx]

How can I monitor a Blueprint's Specific Variable Value and copy what that value has during runtime?

[odd roost]

What is it you're trying to achieve? Simply know what that value is or use it for something else?

[white lynx]

I'm wanting to copy the value to other class's Default Values for the asset itself

@odd roost

[odd roost]

Okay, not sure of the big picture but you should be able to achieve that with an interface

[white lynx]

It's a Map and has a lot of data generated during playtime

so I want to copy that information so that in editor, I can set a variable to that value, then save the asset

[odd roost]

Can you accomplish that with the built in save functionality? I'm not really sure if I can offer more guidance without knowing exactly what you're trying to do.

[white lynx]

Not really, as I want to save a variable's value from what is currently generating during playtime. However, it doesn't let me do that wih the EditorAssetLibrary since that library doesn't allow it to happen when Playing

[earnest tangle]

have you tried using apply instance changes to blueprint?

I dunno if that reflects runtime changes tbh but worth a shot maybe

[white lynx]

I love you

[odd roost]

oh snap! Nice

[earnest tangle]

Oh that worked? Good to know :D

[high sapphire]

Hmm. Is there a way to do a check for if a level exists? Tried searching on Google but I guess the keywords confused the Google Machine..
I tried this, but it goes down the false path even for a level that does exist.

(Main reason is, I have one level created and I plan to make two more but haven't created them yet; I want there to be a check for "if level exists" because by default it boots me to the default level when the level it calls for doesn't exist)

[odd roost]

what is the return value of the build string printing out?

[high sapphire]

That's for the level that does exist

[maiden wadi]

@high sapphire It seems to need a full file path.

[shell jetty]

Bit of a weird question, but is anyone familiar with a weird occurrence where changing a pawn's movement mode causes its collision channel responses to change. We'e trying to find a workaround for this.

[white lynx]

@shell jetty which channels responses "change"?

and how have you troubleshooted these behaviors? What have you debugged?

[shell jetty]

World static and world dynamic it seems. It may be more but we've tested those

We would constantly print a string displaying a channels' response, and then un-plug the movement mode nodes. We noticed that removing all of the movement mode setting nodes keeps the channels from changing seemingly at random.

Also, weirdly enough..the pawn(s) don't fall through collisions while this is happening. They only seem to pass through collisions laterally, but not collision below them(and probably above them)

[high sapphire]

@maiden wadi Maybe I'm doing something else wrong?

[mental sail]

If your first map is loaded from the same path, a relative path might be enough, which means just using the map name

[high sapphire]

So I'd be able to just plug the map name plus the .umap extension into the File Exists node?

[uncut lark]

Does this look like an okay script for a health system?

[mental sail]

I was assuming you want to load a map like so.

Which doesn't need an extension

just the name

[high sapphire]

That's not the entire thing I'm trying to do, no

I'm trying to check whether the map exists

Basically, I'm making a uni project, where I plan to make two more levels but I won't have time before it's due.
I don't want the game to just boot the player back to the title screen when they select the "second" and "third" levels, so instead I'm just tossing some debug text up to go "hey btw this isn't ready yet, sorry" (the professor wants us to submit the raw files, not an .exe, so he'd see the debug text)

Once the other two levels are finished, then I'll be able to remove the "if level exists" stuff, but until then I'm basically doing exception handling, kinda.

[mental sail]

Right, I see, well the Open Level only needs the name, as for FileExists... good luck, the documentation is crap, might be trial and error for a bit...

[high sapphire]

I'm not worrying about Open Level.

I'm trying to format the string so that the File Exists node can go "oh yeah I see that level in the folder, gotcha" for the level(s) that exist.

I may not be a UE4 expert, but I know how to use an Open Level node

[flat raft]

Anyone know what Get Base Aim Rotation returns?

What is the Base Rotation ?

I guess it's the rotation of the controller

NOT

Base Aim is 0 to +-180 where Control Rotation is 0 to 360

It's the Camera World Rotation

[compact basin]

Anyone know a tutorial or a video where i can figure out how to draw a road / path in runtime like Simcity or city skylines? I cant for the life of me figure this out

[flat raft]

draw a path?

[compact basin]

Basically yes

[weary prism]

Guys i need help my project upon compiling successfully is not generating a exe file it generates the shortcut but not the actual exe itself

the exe in the binaries folder defaults to UE4-game.exe not my project name

and to top it off im missing stuff in my binaries folder even though it compiled successfully

this is a very strange bug

im running 4.26.1 btw

[flat raft]

Create a BP, add a spline component, add a var of type Vector Arry

[weary prism]

ive never seen turbojpeg.dll in my life in a unreal project

[compact basin]

This is what i currently have, i can place the asset once, but i cant edit the splines nor do they show up in game

[flat raft]

@compact basin

use spline

What you want is a layered system.

Look at spline tuts on youtube and how to use them to loft a surface

[compact basin]

Ill do just that thank you

[flat raft]

It's not a easy thing to make

[weary prism]

Guys am i doing something wrong im a bit lost as to why the compiled exe wont open

[flat raft]

but that's the basic idea

[weary prism]

anything you guys recommend to help fix

bruh its literally compiling a blank exe

or eqivilant to that

[covert arrow]

i need some help on something if anyone can help as soon as you can.

no rush.

[flat raft]

@weary prism make a copy of your project, then nuke the unneeded folders, and rebuild.

[weary prism]

ok

[flat raft]

BE SURE TO NUKE THE COPY

NOT YOUR ORIGINAL

@weary prism

[weary prism]

ok so copy it and nuke the uneeded folders like how?

[flat raft]

in fact.. zip the orignal also

[weary prism]

ok

[trim matrix]

So I got this line tracing which works if the item if crossing path with the line. However I would like to make it so that I can detect anything that is in front of the character (from his feet up to his head). Anyone know how I would do that? 🤔

[flat raft]

Box collision

[trim matrix]

That would require an overlap check instead, no?

Didn't get that working before which is why I had to switch to line trace

[flat raft]

Box collisions are far cheaper than traces

You can also trace down from his head to the ground if u really want to use trace

But collisions are the way to go for theses kinds of things

YouTube item pickups... there are a million tuts on it.

[trim matrix]

Alright. I know how to do it, it just hasn't worked 😛

[arctic finch]

anyone a wiz at BP can give me a moment of their time?

[weary prism]

Can someone tell me what im doing wrong? ive tried to package my project on multiple diffrent computers with a successful build but no binaries folder im confused on what to do and i do not want to start a new project

[valid musk]

hello everyone ! I am looking for making an melee enemy to my horror game, I want him to walk and if he gets too close he will punch you, I am using the horror engine from marketplace, please somone help me 😦

[valid musk]

I am not sure what are you talking about, can you give me a little more description ?

[vagrant moth]

https://www.reddit.com/r/unrealengine/comments/6lp5y7/how_to_get_straight_lines_in_blueprints/

[unkempt adder]

Hey mate! You can also use multiboxtrace instead. it will give you accurate results, but if there are many items it will cost you performance. What I have ended up doing was using the boxcollisions (overlaps) those are much cheaper comparing to traces because how those are implemented in ue4...

[trim matrix]

Interesting. Will look into it, thanks!

[buoyant zealot]

hey, experiencing bumpy collision on spline mesh intersections. anyone who had something similar and happens to know how to get around that?

[stuck kiln]

Hey guys I am facing this bug that begin overlap event of child bp is being called infinite times when overlapped but it works perfectly and is called once in parent blueprint. Anyone know what the issue is?

[buoyant zealot]

here's how it looks...

[lofty saffron]

looks like "internal edge" issue

normally there is special code for dealing with that in e.g tri-mesh intersection handling

[buoyant zealot]

could you elaborate or point me towards some more info?

[tight schooner]

@buoyant zealot if you're using a collision mesh, try removing the end caps

The bounce seems to be happening where those would be

[lofty saffron]

the balls are colliding with the sides of the different sections

removing the sides if there are any might solve it... or if you can create a single trimesh maybe physx will solve it

but need to removes sides in either case

[buoyant zealot]

i guess you are talking of the mesh faces. will try...

[lofty saffron]

if you google for 'collision internal edge' you will find plenty of people with similar issues

[buoyant zealot]

alright thanks for the hints. will do some research and report back

[atomic salmon]

@buoyant zealot you can usually solve that by adjusting the min and max contact offsets

[astral tangle]

What is the most effective way of stopping projectiles going through walls? I have both the projectile, and the wall set to "block all". Once the projectile hits the wall, it's meant to cause damage and be deleted after that (with DestroyActor). The only problem is, that in the same frame, the projectile goes a bit forward inside the object, and causes other problems. Anything I'm doing wrong here?

I want the object to always stop at the wall.

Using easyballistics plugin

[atomic salmon]

@astral tangle Not familiar with that plugin but turning on CCD on both the projectile mesh or collision primitive and the wall should solve it

Now I know why #legacy-physics is silent, all the physics problems are being discussed here 😉

[astral tangle]

@atomic salmon I'll try the collision primitive, tried CCD already on both objects with no effect. Maybe it has something to do with the plugin though, that I'm doing wrong on that.

thx

[buoyant zealot]

you mean the spline mesh start and end offset?

[lofty saffron]

does it actually use physics for the projectiles? otherwise try sweeping

[atomic salmon]

No, these are global settings of the physics engine which can be found under Project Settings --> Physics

[buoyant zealot]

oh, will give it a try, thx

[atomic salmon]

Use very low values

like 0.01 for Max and 0.001 for Min

[buoyant zealot]

https://tenor.com/view/peace-and-love-thanks-thanks-dude-thanx-gif-12153004

works like charm

[lofty saffron]

most collision shapes seem to have "rest offset", is that the same?

https://docs.nvidia.com/gameworks/content/gameworkslibrary/physx/guide/Manual/AdvancedCollisionDetection.html

pretty good explanation

[atomic salmon]

contact offset is the distance below which a contact impulse will be generated, rest offset is linked to stacked objects and the maximum force which keeps them stably apart

The NVidia PhysX documentation has a good description about both of them

[lofty saffron]

so contact offset can not be set per shape in UE?

[atomic salmon]

no it can't, but you can tweak it on a per-body basis through the contact modification callback if really needed

plus there are body specific flags which affect how contacts are handled

[lofty saffron]

guess I could just go to physx and set it directly

[high sapphire]

Still haven't been able to figure this one out. I've tried Game/Content/2DSideScrollerBP/Maps + Map Name + .umap, I've tried Content/2DSideScrollerBP/Maps + Map Name + .umap, but it always returns false even when the level does exist.

[long smelt]

Isn't it like MapName.MapName_C?

[high sapphire]

So for Twilight_Forest, would that be Twilight_Forest.Twilight_Forest_C?

[long smelt]

Yeah but if you copy the reference from that it will end in Twilight_Forest.Twilight_Forest_C

yeah just copy reference

[high sapphire]

Hm. That still didn't work.

[long smelt]

did you copy reference?

[high sapphire]

Yeah. And the reference didn't end in Twilight_Forest_C.

[long smelt]

hm

[high sapphire]

World'/Game/2DSideScrollerBP/Maps/Twilight_Forest.Twilight_Forest'

[long smelt]

huh

[high sapphire]

Not sure why the 's are there.

[long smelt]

just try and give that to does file exist?

[long smelt]

cause of the World tag

[high sapphire]

Ah

[high sapphire]

Problem is, I need this to check for multiple level names, not just Twilight_Forest

[long smelt]

You can easily format this to fit a different map name?

[high sapphire]

Yeah, trying to figure that out right now

[long smelt]

World'/Game/2DSideScroller/BP/Maps/ + [MapName] + . + [MapName]

I would just use an append node for that

[high sapphire]

Hmm

[maiden wadi]

@high sapphire I tagged you before about that. Not sure if you missed it. You need the full path of the file.

[high sapphire]

That is the full path of the file. I tried Content/2DSideScrollerBP/Maps/[MapName], I tried Game/Content/2DSideScrollerBP/Maps/[MapName], neither of them worked

[maiden wadi]

I mean from disk. For instance, this returns true.

[high sapphire]

Yeah, I tried that, and on my end it didn't work

Or does the "get project directory" also need to be added in?

Yeah, guess it was the "get project directory" that was needed.
Thank you, @maiden wadi!

[high ocean]

I have this running in construction script

when i pull bps in the world, it runs normally. but when i pull the bp around to update it, the skm doesn't update and stays the same as the one it was when i pulled the bp into the world

the int var however does change its value

any idea on why this happens? are skms not updatable at design-time as other params? do they follow some other logic for updating?

[maiden wadi]

Should work fine. Let me throw together a quick test.

Seems to work fine.

Dragging it along rapidly changes the mesh.

[short oriole]

Is there a problem with higher values in loops? When I try to increase the Depth or ChunkSize variable, it says that it detected infinity loop.

[maiden wadi]

@short oriole There can be. The default loop max count is supposedly 1000000 in Project settings. However I've noticed that it seems to count 3-4 loops per loop. So in reality it's more like 3-400,000. You can up the count. Though it's also worth noting that blueprints don't handle multiple nested loops well either. You can sometimes get around this by hiding your loops inside of functions and returning the end results into the first loop's body. In reality, if you need that much looping and data, you're far better off learning to use some simple C++ in some function libraries.

[high ocean]

@maiden wadi Thanks, idk why it does that...

[maiden wadi]

Do you have any other stuff running in your construction script that might affect it?

[short oriole]

@maiden wadi alright, thanks for the response. I guess I will take a look into C++

[high ocean]

@maiden wadi I do, but they all work fine - i attach some random haidos and/or hats and change some DMI params for clothing. All working fine, except this. But this is the first function which determines the others through a switch so idk xD

[maiden wadi]

What happens if you temporarily remove any other logic and only call this one function? If it works, then, you might slowly add back the other logic until it breaks again.

[high ocean]

@maiden wadi same. Only left that function and whatever skm gets set at drag-in time stays.

@maiden wadi hm...nope, my bad...it does change as it should if I only leave that function o.O

[maiden wadi]

Hard to say without seeing the logic flow. But I would guess that something else is either somehow silently breaking the construction script, or you accidentally are resetting the mesh somehow.

[high ocean]

@maiden wadi I'll check, can't ss the whole logic, it's lots of nodes since the dmis and vector param changes for them

but nothing else refs that index, only the skm itself, to get the materials. Idk, it's not the end of the world, was just wondering what could cause it - thanks for the hlp 🙂

[maiden wadi]

I doubt it has anything to do with the index or whatever. Something else would have to specifically call SetSkeletalMesh on your component.

@swift pewter Image as in a Widget's UImage?

Well. Image is Widget. If you have a UTexture2D that you want to set as the visual for that Image, you'd get the UImage and call one of the set functions.

Usually one of these.

[astral tangle]

@atomic salmon So it was the plugin. If it does not have two sided wall, it seems to bug out for some reason with my blueprint scripts. I replaced this shatter effect that was ran with the plugin, with simple linetrace, seems to work well with CCD. Thanks anyways!

[maiden wadi]

@swift pewter Drag off of the cast, and get the Image, rather than Setting it. That should get you a pointer that you can drag off of to get those functions.

That should work fine, assuming you are getting the correct widget, and the texture from the weapon isn't null.

Try this if you want to brute force test it.

Make sure to uncheck TopLevelOnly.

[hexed inlet]

What does this mean? (The two little white baubles)

The variable can be passed from server to clients in a multiplayer set-up.

Oh, ok. I'll look into it some more, ty

When you are ready for multiplayer, this is the best resource I know of for that stuff:

Question: Can I "Cast To" from Get Owning Player in a widget?
It doesn't seem to work the way i think it should.

[full fog]

@robust spoke Could you try to find some setting that may handle loops? Not sure something like that exists in the particle system settings.

[robust spoke]

Hey Kaji , I have heard that the particle systems loop on their own by nature , and you have to stop then in like the blueprints , but that brings the question what nodes do i have to use to lets say deactivate them?

[full fog]

Some "Do once" node may help

[robust spoke]

Okay ill try that! thank you!

[full fog]

and after that, maybe destroy the actor (particle system) .. if you know how long exactly, you could place some delay node in front of the destroy actor node to set some time before it goes poof

@pliant frigate do you get some access/return none?

[pliant frigate]

Here's what I have:
A. Blueprint "Gameplay_PC" player controller class is parent.
B. In Game Mode, player controller is set to Gameplay_PC.
C. Widget has a button with On Clicked Event.
D. In On Clicked Event, I get Owning Player, Cast to Gameplay_PC and have two print strings (Success, Fail) linked appropriately.

If i press button, it always returns "Cast Failed" print string.

If I do a is Valid from the "Get Owning Player" and test, it returns valid.. so its the casting that is failing.

Tbh, I am actually not sure I can help in detail since my BP knowledge is quite basic - but wanna help anyways somehow since Answerhub is dead as hell (Real suggestion @shut grove >> Epic should think about open some subscription based Answerhub, get some support people hired from that money..)

mhm

cast failed... ok

Could you provide a screenshot of the Widget BP?

[pliant frigate]

sec and i will show a BluePrint screensho...

yeah

My Project Settings & Game Mode

I don't see a reason why this isn't working.. but Im pretty new to this stuff.

[full fog]

hüm.. I am actually doing trial and error most of the time (Senior Artist, BP skills like a cow plays banjo)

[pliant frigate]

lol.. that sounds like me.

[full fog]

I would try to squeeze that is valid in front of the cast

maybe that will do something

[hexed inlet]

Hmm I can't find much about not replicating, or if that's important.
I have this, which is just a StaticMeshComponent (the GET with index 0), and then a Get Static Mesh (with the 2 white baubles).

[pliant frigate]

It passes the Valid check and still chokes on the Cast.

[hexed inlet]

So it's replicated. What I'm doing has nothing to do with networking though, so should I be concerned that it's replicated?

[pliant frigate]

Are you working on something that is multiplayer?

[hexed inlet]

Woops wrong screenshot

Nope

It's just part of a BP graph whose job is just to store a ref to all Static Meshes in the level

[maiden wadi]

@pliant frigate What about the map? Are you using project settings on the map, or are the GameMode/PlayerController classes overridden?

[pliant frigate]

Someone will correct me if i am wrong, but if you aren't using multiplayer, I wouldn't worry about it. I think static meshes are replicated by default. I wouldn't mess with it.

[hexed inlet]

ok

Fix it if it breaks something later

ta

Actually just replicate what needs to update to other players..and your own

[pliant frigate]

Well, that's what I missed! Thanks Authaer.

I forget the level has gamemode settings to.

[full fog]

oh?

[pliant frigate]

Yeah, World Settings for the map level also needs to be set, apparently, lol. Glad it was something simple.
