blueprint

[open crypt]

I have area levels, that are "Intact" archetypes, things like a Parking Garage, a City, A factory district, etc

My scenarios are basicaly mini-disasters the player has to fix

Incident management technically

[maiden wadi]

Well. In this case. If your print doesn't fire more than once, it's because some part of your VRBasePawn never level the trigger's capsule. It still considers that actor as overlapping, so it never fires it again. I assume you're trying to make this work when a player's in game hands overlap the capsule?

[open crypt]

context - https://www.youtube.com/watch?v=ZgBImMAkeHo

[open crypt]

I don't care about their hands, I want their pawn to do it - when I check the overlapping actor most of the time, it's the MotionController - but again, I do not care if that overlaps because it has a long laser pointer which could trigger this thing, I want it to ignore that....normally I wouldn't care but it is stopping the overlap from detecting my VR pawn

I'm legit standing in the middle of that trigger box and it's not overlapping

[maiden wadi]

The print does fire once though for the player pawn, right?

[open crypt]

no

Not consistently

What comes across consistently is the MotionController Actor

[maiden wadi]

Hm. Well if it's never showing for the player pawn at all, then I'd wager collisions. What channels is the capsule set on, and what collision does your VR Pawn's capsule use?

[open crypt]

It DOES show the player pawn

just not consistently

[maiden wadi]

Even if you back out of the capsule and run back into it?

[dull gale]

Hi everyone. I could use some help as I don't quite understand what's going on here. I'll try to explain the situation the best I can:
I have a character blueprint and a weapon blueprint here. When reloading, both the character and the weapon have animation montages that play when I press R.
Character animation works fine, Weapon animation does not, returning me a "accessed none" error. I managed to pinpoint the error to the fact that I'm spawning the weapon in my player's hands.
If I connect the "Target M16" to the spawn return value, everything works, but if I get a reference to the class the weapon belongs to, it doesn't.
Could someone who understands Blueprint more than me explain why this happens, and maybe how I could possibly find a way around this? Thanks!

[maiden wadi]

@dull gale You're not setting Test to anything.

IE, it's empty.

[open crypt]

That's tricky - I only have teleport locomotion - so I can't back out - today I'm not in my normal office, so I don't have access to my VR equipment, but I can manually teleport it in there to test for collision

Basically - how do I make it keep it's "overlapability" so it will see my VR pawn?

[dull gale]

So, should it work if I use a "Cast To" instead?

[maiden wadi]

@dull gale No. You should set Test to the actor that you spawned. Test is a container. It's just an empty variable of the type WeaponBase. It knows that it should hold a pointer to an actor that is a WeaponBase, but it doesn't know which one. You have to tell it which one by setting it.

[dull gale]

Oh, I think I'm getting it

[maiden wadi]

@open crypt BeginOverlap is only called once per time that the overlapper enters the overlappee's component. So if you're teleporting into it, it should only fire one time until you teleport out and then back in.

[dull gale]

thanks for the help, let's see if I can fix it

[open crypt]

What happens if something teleports into it one or two frames BEFORE the desired overlapper does?

[maiden wadi]

@dull gale This may help a bit more.

[dull gale]

was about to say, this worked!

[maiden wadi]

@open crypt The overlap fires for that object, then it fires again for the one that teleports into it. It will fire once for every single component that overlaps it. So technically if you have three components on your VR pawn that can overlap that trigger, it'll run three times.

[dull gale]

it's basically what you put on the screenshot, but thanks for not telling me straight away! the best help is the one that helps us solve the problem, not tell us the solution

[open crypt]

Okay, that's what I wanted to confirm, thank you

Confused - triggering what I want, which is this call for this event dispatcher

and this fires before, so I know the event is bound correctly

but the event that is bound to, this doesn't seem to want to fire

[maiden wadi]

Do any prints or breakpoints fire from the MakeStuffFall event?

[open crypt]

No

at least the event itself you see there (3rd image with breakpoint) never breaks

But I am using a new 3rd person pawn and switched it out and it triggers the overlap event (and calling the event dispatcher) consistently every time

and the event that Binds that dispatcher to the "Make stuff fall" fires first, so it's not an order of execution thing

[unborn maple]

is there a reason for only one of my set promote to variable on my widget is failing saying access to none when trying to set visibility. it only one of the widget but in debug it show it storing the info

[open crypt]

The "timing" of your setting the variable is probably off

[unborn maple]

not sure what timing it need im promoting the set variable after i set the other widgets

and there not failing

[open crypt]

is the variable details, maybe it is set to read only

[unborn maple]

it not

the widget are also in the same blueprints

should i add a delay after adding each viewport

[open crypt]

let me see the details of the variable itself

[open crypt]

@maiden wadi that event fires but it goes nowhere? what gives ?

[open crypt]

Try clicking "expose on spawn"

[dapper siren]

Dumb question:
you can only assign a custom event dispatch if you Cast to that actor first, right?

https://storage.googleapis.com/maketheory-send/5270ae58-a5bf-4ec4-b742-91e2bee5582b.png

[open crypt]

I have no idea, and I never thought about that, maybe that's my problem too

[dapper siren]

There's no way to get that custom event any other way i dont think right?

Yah @open crypt , i can't find any other way tbh

[open crypt]

I'm doing it because i need to have events triggered on my level blueprint itself

[dapper siren]

Because the dispatch requires that specific actor

ya

same boat lol

i mean i guess its fine

but

[open crypt]

It's not fine lol - it doesn't work

[trim matrix]

can you use animations on level blueprint?

[unborn maple]

still getting error

[trim matrix]

player animations

[open crypt]

yes

[open crypt]

try the delay, and also put instance editable and make sure it's exposed on spawn

[trim matrix]

Can you use them on TriggerBox and what conponent do i need to make it happen?

[unborn maple]

wowwwwwwww

it was the delay

i miss

[open crypt]

I'm the wrong guy to ask about triggerboxes, scroll up and you'll see I'm having issues too - I'd first make sure you can get the animations to play correctly, usually it's just Set Animation and then play animation

[open crypt]

This is important - play with the delay, try like .1 ms, then .05, then try delaying just a frame or too, figure out where the line is that stops it from working

Also you might try making that add to player viewport a function, with the output being that variable you want

I think encapsulating it in a function might correct the time issues

[unborn maple]

alright thanks for the help/

[open crypt]

No worries, i've always had trouble in particular with widgets

[unborn maple]

yeah this is like the 2nd game im making it a small game but i am trying to learn baby steps.

[open crypt]

You know about how to pass in existing variables when you spawn something right?

Like exposing on spawn and making instance editable, then you create the variable on the blueprint you are spawning, making sure you pick the same object type from the details...then when you spawn it, there will be a node you can pass in?

Btw, what is PlayerNowReady? That seems like a bool and not a widget

[frozen spear]

Quick question: Im working on a coop lan game and in onhit event from my attacks Im trying to get forcefeedback on the controllers and camera shake, Im testing with a listen and 2 clients. all 3 of them are correctly playing thier camera shakes, however...only the first "client" is getting controller feedback, the server and client 2 are not getting any controller feedback....Ive also tried using spawn feedback at location which makes none of them get feedback.

what am i doing incorrectly?

the effects are being issued through a interface message call

[open crypt]

@frozen spear you read the network compendium right?

[frozen spear]

of course 🙂 but is there something i should look deeper into there?

mind you im like 8 months into dev on this multiplayer game

[open crypt]

Well if you got the forcefeedback back to fire once, then you know at least the implementation of force feedback is correct, and it's probably a replication issue

[frozen spear]

right, im using the client play X nodes

[open crypt]

Are you able to print out from the same event on all three? Basically have you confirm that the event is being broadcasted correctly?

[frozen spear]

let me check that now

i should mention i only want the person that did the attack to experience the cam shake(which is working) and controller shake(which only works on client 1)

[open crypt]

It might be as simple as just not having the node checked for replicates

On Your controller shake

[maiden wadi]

If you're on a listenserver setup and only the host is getting feedback, then it isn't being replicated, or your programming is serverside and does no local effects.

[fallen glade]

Can someone help me run this project please? https://drive.google.com/file/d/1N6NZBdEv3pV3OUrbwKWUnOhmE9E2fJFS/view?usp=sharing I'm getting an error no matter what Blueprint I try to open or right click on. It's a simple game I've made for a company. I had to work on a mac book over the holidays and now I'm stuck. Delivery is in like 10 day lol. Please can someone have a look?

[open crypt]

@maiden wadi can you advise about why a custom event bound to an event dispatcher, where I've confirmed that the bind executes, and the call executes, why the custom event isn't firing?

[maiden wadi]

@open crypt Very hard to say. Initial thoughts are either that it's not being called, but you said you've seen the print just before that so it likely isn't that. Other idea is that your're calling it from an instance that hasn't had that dispatch bound. Assuming that both of those are false, I'd look at race conditions, but you've confirmed that the binding happens long before the call does.

[frozen spear]

the host doesnt get it, and only 1 of the 2 clients do...let me just redo this and see if its a replication issue. ill be back shortly 🙂

it become a replication issue i think becuase onhit is a server called event...so i just have to see how to work it to the correct clients

[open crypt]

I've gotten it to fire before

the event happens on a level bp, if that matters

More information, this should help you @maiden wadi I'm using multiple instances of that Trigger Actor - while both overlap fine, only one of them successfully fires event on the Level BP - so what is it about event dispatchers and instances that I am not aware of, clearly that's the issue here

[maiden wadi]

Being on the level blueprint shouldn't matter at all since you have references to the trigger there. As for the binding, that shouldn't be the issue if you're using the correct pointer to the correct binding event.

[open crypt]

oh crap

that's it, i'm an idiot

I only referenced one of them

so the 2nd one was never added in there and bound

Ugh, there should be an easier way, I wanted an Actor who can send out a broadcast to any level BP and trigger events - the "call" could be the same, and the only thing I'd pass is an event number, then each different level could use it and fire unique events, but still numbered @maiden wadi any advice?

[exotic cradle]

@unique harness So quick question. What would be the easiest way to debug the system I was working on that you’ve helped me with. I ask because I am able to place all the blocks I want but only on the front and the back of the mesh and it doesn’t allow me to place on the top and bottom nor the left or right sides of the mesh despite having sockets and their locations. I’ve been going at it for a couple days now trying to see why it wouldn’t let me and I have not produced anything productive in terms of finding out why it won’t let me.

[olive sedge]

I want to display a bunch of widgets that i create dynamically. Is it enough to have a Horizontal Box and AddChild my widgets?

[frozen spear]

ok so after some debugging...all 3 see the same ts_controller when using the engine to debug 3 clients on the same system....im guessing this will have to be something I test with more than 1 computer to see if its working correctly

[split crescent]

Anybody know why this doesn't work when I set interp speed to anything other than 0? If it is set to 0, it rotates my character in 1 frame. But if I set it to anything else, it doesn't rotate at all

[edgy halo]

Hey so I am scripting on the default Character class, but want the camera to be stagnant and not follow the character? Any help on how I can do so?

[dawn gazelle]

Is the execution path it's on fired every frame?

ie. through a timeline or on tick

[split crescent]

No it is called when I press left mouse button

[weary jackal]

@edgy halo you mean camera should stay at the constant place and the background should change?

[edgy halo]

No like the character should be able to move but the camera should stay at the same place

@weary jackal

I kind of want it to be a top down view, but the camera shouldn't move at all

[dawn gazelle]

So that's the issue - you need a continually firing path for that to execute right. You could use something like a gate to control it.

[weary jackal]

well disable the camera in character bp and use a camera in level bp

[edgy halo]

where can I do that?

[weary jackal]

'set blend with target '

you can add a camera in your level

[edgy halo]

Ohk thanks

got it!

what are the advantages of using a character rather than using a basic actor class?

and scripting it yourself

[split crescent]

@dawn gazelle thank you very much 🙂 it works now!

[weary jackal]

basic actor class is only a simple class with almost no major inherited parent methods.

[frozen spear]

yeah its an engine issue, even just using a key event press, only the last player loaded on the same computer is the one that gets the controller shake....going to just assume for now that its working on all 3 players, since the camera shake is working perfectly on them and its executed in the same line of code

[weary jackal]

character class do have character movement, a capsule , and many other pre defined methods

[edgy halo]

Alright thanks a lot for your help!

[open crypt]

So, I've realized something regarding this - you need to bind an event to each instance of the actor sending that event dispatch call

Seems obvious but my problem was I was treating each instance of the actor like it was just THE actor

once I dropped the reference to the trigger BP actor into the level BP (I only did it once, not for each one) and make a bind event, it worked

But at this point, I'm thinking it makes more sense to do an interface call

How does this look @maiden wadi - I need to make stuff happen on the individual scenario level blueprints hey are basically empty sublevels loaded with their area levels, where I stream in ruined buildings or effects, etc -

I have a trigger BP actor that I use to generate an overlap event - this event calls on an interface that makes various unique events happen, I'm sending out an interface with an INT input, that way when the level BP receives the interface call, it can switch on INT from the same event, but do different things - I have it working, but I wanted to make sure that this implementation won't lead me to problems later on. -before I was using event dispatchers which were working but I couldn't figure out a way to bind each instance easily, without just having it as a separate binding event - which method do you think is better to use?

My concern is mainly from the Trigger BP's getting the correct level instance - I guess I could control the logic but as long as I only implement these events on scenarios and only one is ever loaded at once, it should be fine

[edgy halo]

@weary jackal so I did that but I can't get a reference to the camera in the level? How do I get it?

Ohh nvm I understood

[unique harness]

Print statements and learn to use the unreal debugging with breakpoints.

[unique harness]

Yes

[olive sedge]

@unique harness late reply but thanks!

my problem right now is that only one of the child widgets shows up

[exotic cradle]

I have but it’s outputting what it’s supposed to but not actually doing what it’s supposed to do that’s why I’m stuck lol. I’ll try again in a bit once I’m free. Thank you for the help you have provided so far

[dapper siren]

@open crypt interesting thank you for sharing

[hollow drift]

OK i am banging my head against a wall again. How to use "Dynamic Material Instances" proper?

Here the situation: I have a field of Different Tiles. Those tiles when uncovered will be replaced with a new Bp while the old one gets destroyed.

What I want to achieve: If you pick up the pawn, all tiles nearby will be highlighted (including the uncovered ones). In order to do so i have to create the "Dynamic material instance" to manipulate my Material Instances on runtime.

What I cannot understand: How to create the "Dynamic Material Instances" globaly and assign it to a specific Actor of my choice throught my PlayerControler. My PlayerControler already chooses which Actor should be selected.

What I got so far:
I could get it to work inside of my Playercontroler. But there it Loops throught an create Dynamic Material Instance each time i pick up the pawn to color in which valid tiles are accessible. I fear this will tear much on performance.

My second attempt on performance is to make the "Dynamic Material" globaly so I can cherrypick for which Actor it should apply later (I hope this is the right approach):
Either it does not work (above script)
Or either my whole Map is Green.

[olive sedge]

I can't find anything on this: how do you find the screen space extent of an actor?

I want to display a widget above (in screenspace) the actor

[open crypt]

@olive sedge I think you need a 3d widget, which you could resize dynamically based on a box that is on your actor

[olive sedge]

@open crypt I had a widget component on my actor so far but I can't place it above my actor in screenspace

if I place it on top of the actor in worldpsace an move the camera to be ISO or top down, it will be over the actor in screen space

and hide him

[keen seal]

Hey, this is a very simple blueprint to make the enemy always face me.
However it doesn't work, he just moonwalks towards me

[fair sun]

@keen seal Your start location should be the enemy actor location

rn you are finding look at rotation from player to player which is probably 0,0,0

also +1 to SetFocus

[keen seal]

Yes!

Thank you

Sorry what?

[fair sun]

What what? 😄

[keen seal]

oh whoops

didn't see Datura's image

[lament ginkgo]

Hey all, I have a question - still a little new but I need to get a lot of information from a pawn to a controller. So far I've been doing a cast from the controller, but having to do it for every single aspect is tedious. Is there an alternative to cast for when you need to get more than one piece of data?

[fair sun]

You can promote it to a variable and use that variable

[lament ginkgo]

You mean to like a global variable? (I have lua background)

[fair sun]

If you promote it to a variable in your pawn class it will stay inside your pawn class

but it will be visible to other classes

all variables in blueprints are public by default

[lament ginkgo]

But don't you still need to cast for each one? Like say I have three variables I need to get, would I not need to do a seperate cast for each? It feels like only the connection immediately from the cast will go through.

[fair sun]

also you can drag off that cast node multiple times

if you cast it and then promote it to a variable it will store it as a player controller

so no need for further casting

[lament ginkgo]

Oh, so you're saying cast to my pawn and then promote THAT to a variable.

[fair sun]

yes, that will work

[pulsar moss]

LogScript: Warning: Script Msg: Attempted to access index 0 from array 'targets_52_051026F94335D78F715F8199768DE133' of length 0 in '/Game/Operator/Combat/F_OP_Action.F_OP_Action'! How do I actually find the offending node here? This warning gives no indication which BP it's coming from

[livid iris]

New blueprint user here, coming from Houdini.
How would I create a constant value (float, vector, matrix, whatever)?
For example, i have a direction vector and want to multiply it with any constant value, say 3.624.
In Houdini I would create a „constant“ node, set type to „float“, and set value to „3.624“.
What is the blueprint equivalent?

[pulsar moss]

@livid iris depends on what's running the code, all variables must live somewhere, usually on an Actor or Component

one way is to create a blueprint function library and make a function return some constant, that would be accessible from everywhere

[livid iris]

@pulsar moss
That sounds interesting. Thanks.
To specify my question:
A Niagra module (point attraction force) is running the blueprint. I dove in and wanted to do some modifications in it (is that the way to go at all?).
I like the way blueprints work, very intuitive

[dawn gazelle]

The BP should be F_OP_Action, and within it an array named "targets" or "targets_52"?

[pulsar moss]

there is no array named targets, the name looks dynamically generated

@livid iris I like blueprints a lot more than Houdini nodes, Houdini tends to have too much lingo, VOPs etc

SOPs

I keep getting confused

[livid iris]

@pulsar moss
Both are great.
Back to my question.
How would I do that in a Niagara module?

[pulsar moss]

I've no idea, never used Niagara, but if it can call blueprint then you should be able to just call the blueprint library function to get your constant

[dawn gazelle]

But you do have a BP named F_OP_Action? Going to guess that maybe it's a line trace and you're trying to grab result 0 from its array?

[pulsar moss]

@dawn gazelle nope that is the name of a structure...

[strange pike]

does anyone here know how to run a function everyframe for a duration?

[pulsar moss]

is there no way to interrupt on access to index out of bounds? UE4 can automatically pause on accessing invalid

@strange pike you can use a timeline for that if you don't need it to happen exactly per tick

otherwise use a timer and check if the timer is active in your tick

[strange pike]

@pulsar moss how would i set that up?

[pulsar moss]

here's a video on how to use timers https://www.youtube.com/watch?v=QcN04l3Vlxk

I would just google for that. "UE4 blueprint timers"

[strange pike]

apolgies. i meant the timeline

[pulsar moss]

same, just google for timeline

right click add timeline, set it up, faster to google than me explaining it 😛

timeline node looks like this, your "thing to happen every frame" happens on Update pin

if you need to know the progress of a timeline you can create a float curve that goes from 0,0 to 1,1

that gives you the 0 to 1 variable you can use to measure normalized progress

if you need to know exact time you can multiply that value by duration

this controls duration

[tardy kayak]

Any one got a good solution for having a preview of materials like this image. I just need a way to display the materials as 2D textures with out saving as 2D textures then uploading them.

[pulsar moss]

if you need to play at variable duration, you can just set the timeline's playrate to 1/duration

[pulsar moss]

you can set a brush from material

[tardy kayak]

ok thanks

[pulsar moss]

Finally found it 😄

[wooden holly]

Does someone know how I can move the camera with WASD?

So that I have a floating camera

[rotund basalt]

@wooden holly
http://letmegooglethat.com/?q=UE4+create+floating+pawn

[exotic cradle]

Yeah. The reason it wasnt working at all was because my character BP wasnt communicating or using any of the functions inside of the MasterObjectBP. Found that out after 50 print strings and a few break points. 😄

Also the thing with having the masterBP set socket availability it seems is that regardless of what mesh I use the 1 socket it sets to "unavailable" than becomes the only socket I cannot attach to.

[jade bane]

How to add UI widget to certain viewport? Not the first Viewport. But choose one of the other Viewports like 2, 3 or 4?

[dawn gazelle]

?

This one is used if you're using splitscreen I believe.

[jade bane]

will check it out, thx

[wooden holly]

That doesn't help me at all. I already searched the whole internet, therefore I'm asking

[tiny locust]

I want the floor to fall when I wal on it, I did that, but for some reason the "hit event" doesnt seem to be working as I intended

I tried the event "Event ActorBeginOverlap" but it didnt work

[jade bane]

omg this is hilarious 😄

[sweet swan]

Every so often when I'm working in blueprints my action selector (the popup that shows up after right clicking or dragging a node in a bp) starts flickering a lot and then shows a black box. I can still type and hit enter but I can't see the selection. Anyone had this happen before?

[jade bane]

To have a UI in one of multiple Viewports, You just have to have the one you want active

so it jumps between viewports, lols

[tiny locust]

but what should i do lol

[orchid garden]

this is something i've never gotten about unreal.... you setup a new project with some content and....

your stuck at 39% because its 'compiliing shaders'... but....

once it finally loads its going "8k shaders compiling"

[hearty moss]

might want to double check "generate hit event" or whatever it's called is true in the object blueprint

[clear temple]

Cause it's compiling the engine stuff and some of the normal shaders

[orchid garden]

if it were the normal engine shaders, it wouldn't take some projects 5 hrs to load while others will load in minutes.

and if you look at the task manager - its just shaders compiling thats using up all your cpu.

[clear temple]

Huh well I don't know sorry

[orchid garden]

this one only took 10min to load and after in...

oddly enough, shaders seem to compile 10x faster once the engine is up.

[hearty moss]

"only" 10 minutes? how big are these projects? jeez

[orchid garden]

its the shaders the developers used... some of them are serious overkill for what they are trying to achieve.

'marketplace content' need i say more?

i.e. good example is that 'city park' that was given away a couple months back, 1/2 the people that downloaded it couldn't even get the thing to load up lol... I managed to but man it was sooo freaking laggy inside due to how the scene was done and the shaders.

[hearty moss]

you should start migrating marketplace assets instead of importing the entire thing into your projects

oh yeah some will be bad for sure

[orchid garden]

oh i don't, i make seprate projects to pull out what i want from them 🙂

[tardy kayak]

so i want to get the material of the cube and make it a 2D texture that i can apply to a widget but when i cant seem to get it to work though when i hand select a texture it does change the widget

[stray island]

Who knows about hierarchical instanced meshes?

I want to make there transformation so that one is say 20 up in z direction , then next is 20- and so on

Smth like this ^

[queen lichen]

hello there 😄 ive seem to have issue to get these spheres to trigger a point system that ive set up. (red takes away points, and green give points)

this is the blue print for the "give points" both the take and give are the same just the take blue print has a negative.

[stray island]

Why actor begin over lap isnt connected?

[queen lichen]

the point system is set to if over lap give player point, im not very experience with blue print yet :/ .

[hearty moss]

i believe you should be able to delete the orange overlap node

[stray island]

I meant why this isnt connected

Its pointless this way , isnt itv

?

Did u add collisions to the actors ?

[hearty moss]

I'm pretty sure the orange overlap being connected to 'other actor' on the regular overlap event is causing it to never fire the event

@queen lichen you should be able to just delete the orange overlap node and it should work just fine

[slow niche]

hey folks. does anyone know of a way to intercept an actor selection change in the editor?

[queen lichen]

@stray island the objects have collison, but there not actors. ive try ur way of connecting, it still isnt sending points to player, but im not using actors, i think i see why it isnt working as i continue to type.
@hearty moss ill see if that work.

@stray island ok so one sphere is a StaticMeshActor, and the small one is an asset.

[stray island]

I’m not expert but i would make an actor and add the assest static mesh to it too and add a collision to both actors

Box collision

[queen lichen]

@stray island u maybe on to something there 😄

[stray island]

@queen lichen why

[queen lichen]

@stray island wait the blocks are actors already, whoops @_@

[stray island]

U said theres an asset

[queen lichen]

im sorry, im not reading the first subjugation correctly 😦

[stray island]

I’m just saying make each an actor and add collision box

Dont leave them as static meshes

Or u can make an actor and control what ever static mesh u want through a variable

Anyway i think watching blueprints basics would save u tone of time

[lament ginkgo]

Hey, I seem to remember being able to run unreal and see the debug path through blueprints in real time, but it's not doing that anymore. Am I doing something wrong?

Oh it works for the pawn but not the controller

[olive sedge]

@lament ginkgo make sure you use the debug filter next to the play button

[zealous moth]

anyone recall how to access the material from a component being hit?

[lament ginkgo]

Thanks. One other question - I'm using a set view target with blend. Can anyone suggest the best way to wait for it to complete before continuing in the blueprint?

Here is a courtesy reminder about the Create Event node. No more red lines everywhere.

[robust cliff]

when using a blueprint interface, is it better to use trigger volumes separate from the actors or volumes attached to each actor?

Does an actor have to have an interface on it to interact with other interfaces?

[zealous moth]

@robust cliff it depends on what you want to do. If you want to interact with the actor in a sense of player -> actor, then do it at the player level. If it's the reverse, do it in reverse.
Interfaces work as subscriptions. When a trigger is met, you send a message to whatever. If it has the interface, it will respond according. If it doesn't, nothing happens.

[robust cliff]

Lets say that I have a bunch of cannons in a row and I want to trigger them all with the character when he enters a volume? Would I have to have a BPI on the cannon class and the character, or just the cannons?

@zealous moth

[zealous moth]

just the cannons

well, wait

so your logic is "when player overlaps cannon's volume, trigger", right?

i mean at this stage you don't need an interface

[robust cliff]

Well. I want all say.... 10 cannons to continuously fire until leaving the volume.

[zealous moth]

Oh then you shouldnt use interfaces since it is fire and forget.

You should use on overlap begin and check if your actor is the player char. Then set up a timer and turn it on to do whatever.
On overlap ends then just turns the timer off.

[olive sedge]

I'm down a really really deep rabbit hole right now, trying to find the box extents of an actor in screen space.

there's a function: FVector AHUD::Project(FVector Location) const

and that's where the rabbit hole starts

there has to be an easier way?

[haughty belfry]

ConvertWorldLocationToScreenLocation wouldn't work ?

[olive sedge]

I don't think it would.. I tried this many hours ago and it didn't work but I'll give it another shot

[haughty belfry]

Its the way i would have gone but never tried... get the corners of the box -> convert to screen -> calculate the extent

[dawn gazelle]

Doesn't look like it. Are you able to make your own BP Function Library and throw that in there?

[tight schooner]

@hushed gazelle compose transforms

[dawn gazelle]

That multiplies transforms.

[sonic cipher]

Can someone help me please, the set rotation doeesn't work it's like random https://gyazo.com/5168f5dbb0ad2320e59fd66867cd7b18 https://gyazo.com/e7d3c0eb8f568fa8cac028fc93408eca ?

[tight schooner]

Yeah i suppose. It won't add scales

Adding scales is a weird way to use transforms anyway

[sonic cipher]

I don't want to set the rotation with the ticks, this should work but ..

[marble tusk]

I'm not certain, but doesn't these bottom two act like adding and subtracting? I've confused myself trying to work with transforms a lot

It's really confusing with how they're named and all

[tight schooner]

Yeah I don't get it either. I think compose transforms just does the thing https://docs.unrealengine.com/en-US/BlueprintAPI/Math/Transform/ComposeTransforms/index.html

I don't think it, like, multiplies location vectors but I don't have UE4 open in front of me to test

[royal rain]

hey so i made some spline code that i followed Ryan Laley Games for a tube, i have a ball i would want to roll inside the tube but its just falls through, i have the collision set up for the same tube but without spline, i want the same collision with the splineless tube for the tube with spline, also the back end of the tube is filled in when the original tube is not.

can anyone help with that

[tight schooner]

@royal rain all I can say is you need to use complex (mesh) collision if you want spline meshes to collide, cuz they're essentially deformed meshes and using non-complex collisions will produce unpredictable results

[dawn gazelle]

Here's what they do in C++:

KISMET_MATH_INLINE
FTransform UKismetMathLibrary::MakeRelativeTransform(const FTransform& A, const FTransform& RelativeTo)
{
    return A.GetRelativeTransform(RelativeTo);
}

KISMET_MATH_INLINE
FTransform UKismetMathLibrary::ConvertTransformToRelative(const FTransform& Transform, const FTransform& ParentTransform)
{
    return ParentTransform.GetRelativeTransform(Transform);
}

[royal rain]

@tight schooner can you explain what you mean further

i want a tube i can roll inside of for a racing track

[tight schooner]

Unfortunately I have to go, sry

[royal rain]

ah thats ok

[marble tusk]

Are you setting the collision of the spline mesh to how you're doing it with a static mesh?

[royal rain]

can anyone else help from here

idk

i set up my collision that works in

a static mesh

the spline is a class and i used the tube mesh with good collision in the blueprint

idk what you mean sorry

not the sharpest tool in the shed

[marble tusk]

I think spline meshes have their own collision settings and it doesn't just copy from the static mesh it uses

[royal rain]

ok so how do i edit it

also

the tube is smushed

until you extend it

idk why

his isnt

[marble tusk]

In the blueprint wherever you've got the spline mesh. If you're using an Add Spline Mesh Component node, then select it and you should have all the spline mesh's stuff in the details panel

[royal rain]

yeah

and then what do i do the static mesh should be good there

this is what i mean by its smushed btw

not the prettiest tube but yeah

maybe i didnt apply the convex stuff yet

???

for the new spline tube?

that might be it

it kinda was

its stiff very

invisble wall hitting

its a crappy tube someone gave me becuase i needed one quickly

buit still

[clever lark]

Hi everyone, can someone with me with patching? I am able to create the first patch file (with _P) but on 2nd change, I can not get another patch file. It always creates one single patch for the same release. So how I will have multiple and incremental patch files for the same release?

[marble tusk]

Keep in mind spline meshes need verts in order to bend, so if the collision isn't subdivided to match the bend of the visual mesh, then it won't match when it bends

[royal rain]

yeah it stops on invisble walls any help maybe at least i can kinda roll in it, might need to wait for a friend to help fix it

with me

the friend who gave it to me said that the mesh has the ablitiy to cruve like you said

.and i saw it

[marble tusk]

ah, okay

[olive sedge]

Any idea why this comes out totally different on server and client?!

https://i.imgur.com/JhH7pfS.png

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

Red/Orange is server (correct), green is client (way off!)

[royal rain]

but like

thats my collsions

very

glitched out

wasnt there a setting to help get the collsions generated better

complex

[marble tusk]

I'm not super knowledgeable about collision stuff, so I'm not really sure where to go at this point

[royal rain]

ok one sec

let me test something

ok so like do i have to replace the old spline if i updated the collisions

or should it automatically do it when i play it

[marble tusk]

¯_(ツ)_/¯

[stray island]

Is there away to add a rotation movement to an actor and control rotation speed via variable without Event tick

[royal rain]

ah ok

[marble tusk]

I need to get back to my stuff, hope you figure it out!

[royal rain]

well i feel acoplished either way so ill wait until my personal friend can help mje

i need to do check points though before i do

[dawn gazelle]

A timeline

[royal rain]

but at least i tried and got the code in there

ill be back one day

[stray island]

It would loop rotation?

[olive sedge]

https://i.imgur.com/vKYUz5Z.png

Anyone an idea why my GetActorBounds is completely off on the client (red) but fine on the server (green)?

but only on the models on the left and the right

[dawn gazelle]

Timelines can auto-start, can output float values, and they can loop. So you can take the output of the timeline and plug it into whatever you want it to do.

[olive sedge]

Particle system!

[lament ginkgo]

Question: If I'm running around as a player character, and then possess a pawn... and then unpossess the pawn - do I immediately revert to the character or do I need to explicitly re-possess the character?

[stray island]

Plugging that into construction script would make the object rotate in the editor?

[dawn gazelle]

Can't be placed in the construction script.

[stray island]

Oh , why , sorry i wanted a construction script one should of specifed

[dawn gazelle]

You have to tell the controller what to posses.

[stray island]

I want it to rotate anytime placed

[dawn gazelle]

Not possible VIA blueprints. Only thing you could do is have the object have it's own animation BP set up.

Construction script is only really meant to fire once and that's it. There's no access to delay nodes (for potential looping), timers, events, etc.

[stray island]

Its POSSIBLE VIA BLUEPRINT

[zealous moth]

there are several ways to add rotation. check this video:
https://www.youtube.com/watch?v=pfeF1ONTRWQ

uh oh

[maiden wadi]

I love how he compared timers and ticks, and just kind of glossed over the fact that ticks are framerate independent when you do the math correctly. He also failed to make sure his lighting was set to mobile for all of his tests, which will have a huge impact on moving objects, and also did not disable all collisions on the root object. Having collisions on the root dramatically increases the movement cost of objects since it has to check for sweeps.

[true valve]

Is there a way to disable a component?

[stray island]

Useful video , i guess i will use rotation movement component but can we set its rotation values as variables

[maiden wadi]

Not a bad video for basic understanding, but the tests were a little shallow.

[stray island]

Whats ur opinion in best rotation for performance

[zealous moth]

i personally use the material rotation whenever i can

[maiden wadi]

Really depends on the use case and requirements.

[zealous moth]

if not, the rotation component works fine

[maiden wadi]

I mean the best rotation in the world is a flipbook of textures, performance wise.

[stray island]

But can ee set rotation component values as variables ?

[zealous moth]

sure

[stray island]

Rly

[zealous moth]

you can set them all as variables

[maiden wadi]

But it's one directional. The Shader is probably the second best, but like he pointed out, not that good on shadows.

[stray island]

Like its x y z?

[twilit heath]

@stray island best rotation, until you have a game that is more or less finished is the one that is easiest to read and understand

[maiden wadi]

For all other movement, you're not going to see much difference between tick, component, and timers. But the component does usually win since it's easier to use.

[zealous moth]

yup ^

[twilit heath]

and optimizations are required only if makes a significant entry on the profiler

[stray island]

Another question is increasing an assest scale affect performance by any means

[zealous moth]

no

[twilit heath]

it is far easier to optimize after the fact then you might think

[maiden wadi]

Yes and no. Usually no, but increasing scale does effect culling. Larger objects cull less and can stay in screen view easier.

[zealous moth]

what do you want to rotate? entire characters, a coin, is it purely visual? or do you need physics involved?

[stray island]

No physics

[zealous moth]

then do it via material

[stray island]

Just a duplicated object

Thanks guys that was informative I will try these things

But these wont rotate in the Editor only material one would , correct ?

[olive sedge]

Anyone know how to find the highest screen position of a box/extent?

[honest raven]

Hey guys. How would I go about making it where a group of nodes and the code they run could be triggered by another object? Beginner here just making an elevator door. Made the code that opens the doors and sets the elevator LED text to open/closed but now I am adding a switch that I want to be able to use to perform the action of opening those doors.

[zealous moth]

yup @stray island

[desert storm]

When the player uses the button, do you want them to have to look directly at it, or just be close to it?

[honest raven]

Just within the box collider nothing complex

I think I may of figured it out but not sure yet lol.

It'll be an And type thing. Player inside box collider and button presses

[desert storm]

I think that'll work, but I'll check how I did it and let you know.

[honest raven]

Thinking if I create a boolean for OpenDoor which is turned true when both of those are true, then I could use the True of OpenDoor as what the code inside the door that controls the animating and such waits for

Yeah that was an ass explanation lol. Just unsure how to get the boolean to be what the code waits for within the elevator nodes. Atm it's box collider driven so I'm guessing I erased that. Create the reference to the button, get the OpenDoor boolean ..... And then branch off ....

If branch is True then it sets off the rest of the code? Something like that lol

[desert storm]

Sounds about right, you're on the right track

[dawn gazelle]

Thanks for this. I was able to set up the material rotation on one of my static meshes. Looks good 😄

[desert storm]

@honest raven As far as triggering the elevator button goes, I think that you can do an "Enable Input" node inside the button when the player overlaps it. This enables the ability for it to read a player's button presses. You can then use a simple "E" or "Left Mouse" event node or whatever to trigger the button. Naturally, when the player stops overlapping you'll want to disable input.

That's a rough explanation. Let me just get you a screenshot.

[honest raven]

Awesome. Is there a way to group together nodes into a single new event or function that can then be called? Would probably look better in the end for the OpenDoor being true to just activate ElevatorOpen function which has the code for all that inside of it. But that's probably something for later

No I gotcha. I'll give that a shot as well thanks!

[desert storm]

Yes, on the left-side of the blueprint editor you can create a new Function, and then call that Function whenever you need it.

I got the screenshot anyway, this is what I had set up for a simple open/close door thing, but I'm sure you can easily adapt it.

[zealous moth]

@dawn gazelle small detail -> add the node TransformVector from Local to World if you want the object's Y or X axis

[honest raven]

Excellent thanks @desert storm. If you don't do Enable Input would it still be able to detect the button press?

[desert storm]

I don't think so, but as far as I know your "Player inside box collider and button presses" should still work. I don't know for sure, though - you'll have to experiment with that.

[honest raven]

So far it's not responding. Here's what I put together so far. Testing by just printing a string if it detects the player is inside the collision and E is pressed

Feels like a sequence issue. Or like it's only running this once as soon as I trigger the collider so the branch is false as it isn't waiting for my button press or something like that

[dawn gazelle]

Windows Key +Shift + S is your friend.

[honest raven]

Hmm yeah .. maybe the set after Interact is Pressed should connect to the branch @desert storm ?

[dawn gazelle]

Unless of course, you're on discord using your phone, and the PC doesn't have discord on it XD

[honest raven]

Lol

[desert storm]

Worth a try, I'm at a loss on it

[honest raven]

Yeah Im on my phone

Haven't added discord to my comp lol. Should probably do that

[honest raven]

Hahaaaaa yeah that was it

It was triggering the whole thing when I entered the box collider which was too fast

Here you go @dawn gazelle im on my PC now haha

[dawn gazelle]

I don't think you need the Enable input node there. Not doing what I think you think it's doing.

err wait

nvm

I was thinking you were using a BPI.

[honest raven]

It worked with the print string, but now as im referencing this button in the elevator door itself where the opening timelines are, it is giving me that " Accessed None while reading property ElevatorDoorRef " when trying to open the door through this OpenElevator boolean.

which is a common thing this is where im getting confused. I thought creating the reference for the ElevatorButton, being able to get the internal variables and such, means the engine knows what I'm doing. But seems like im missing a step somewhere

this is what im attempting. When OpenElevator is true, trigger the timelines to open the doors. But it gives me the error message and wont work @dawn gazelle

[dawn gazelle]

How does the Elevator Button Ref get set?

[honest raven]

oh the variable has to be set first before it can be used?

[manic knot]

Hey everyone! Anything more reliable than the IsFalling node to determine if my Character isnt on the ground? Doesnt seem to work to prevent doing something while jumping or in the air! Anybody have a better solution hopefully not requiring traces

[dawn gazelle]

Depends. If the Elevator Button Ref is a component of ElevatorDoor then it should be ok.

But if it's not attached to the actor in any way, then you need to give it that reference.

[honest raven]

its not. its a separate actor, mainly on purpose i wanted to get used to the whole blueprints communicating between each other thing

ok, so when doing this sort of thing, creating a variable that is the object reference, you have to Set the variable before you are ever able to use it

[dawn gazelle]

You're using a character or a pawn?

[manic knot]

@dawn gazelle is an ALSCharacter

[dawn gazelle]

Absolutely - Again, components that are attached to the actor are normally fine to reference, but anything not attached the actor won't know what object is that you're trying to reference.

Just like I did with that above screenshot for uzi... I can reference Character movement without setting it as it is attached to the character.

[honest raven]

gotcha. so the Set of the variable reference is like ... the confirmation to the blueprint that ElevatorDoorRef is ... what i said it was lol

if its an outside component

so set the variable, then i can go ahead and get it and use the OpenElevator boolean to trigger everything,

[dawn gazelle]

No.

Set = assign the variable a reference.

Just like you can set a boolean

You're setting the value of that boolean to true or false.

So when dealing with objects in the game like an actor, and you want a reference to a specific actor, you need to somehow get that reference from somewhere, then you can set a reference to it.

Example, I have an object in my level of class "PatrolPath" I could run a "Get all actors of class" in a blueprint which will get me an array of all objects that are of that class. I could then loop through them like so...

or, I can get a specific reference to a single one (if I knew which one in the array I wanted, which most people wouldn't know using this particular way of getting the reference)

Then I could say, set a reference to that particular get I just did...

So then whenever I call Patrol Path Ref, it'll reference the first object that was in the array that the Get all Actors of Class returned.

[honest raven]

so when you create the variable and give it the Variable Type " Actor Name ", and can then drag that variable in and Get it and you can then drag out and get the variables that are within that objects blueprint, why does the engine still not have the data it needs to know whats what? Sorry lol.

[dawn gazelle]

Because it doesn't know which particular actor you're talking about.

I could place 100 patrol paths in my level.

[honest raven]

even though you chose the name of the actor within the drop down and all that? interesting

ooooo i think i see where you are going

[dawn gazelle]

If you don't have the reference to the specific one you're trying to work with, then you don't know what it is you're working with.

[honest raven]

so if i added like 3 ElevatorDoors to my level, I would be using that same object reference for each one

so this is the engines way of making me tell it exactly whats what

[dawn gazelle]

No - you wouldn't be working with any of them.

[dawn gazelle]

you have to get a reference to the specific one you want.

[honest raven]

or buttons i should say lol, since that is what im trying to reference

[dawn gazelle]

When you're defining a variable's type, all you're doing is saying "This is what can be contained in here".

Just like you create a boolean variable, all you can set it to is true or false.

When you're dealing with another object (like your buttons) you have to set it to the specific reference of an object of that class.

So if I had something like this...

When I press F5, it'll get all actors of that particular class that exist in the level, then set the value in my Patrol path Ref to the very first instance that the get all actors of class found.

So it could be any of them in the level, I wouldn't know which.

[honest raven]

gotcha, so how do i set the specific reference. Just drag in the variable and set the variable? or do i need to connect something else to the Set to make it work

sorry lol, im extremely new this is day 3

[dawn gazelle]

S'all good

[honest raven]

and ive run into this same error like 10 times so lol. its my first wall

[dawn gazelle]

You need to somehow get a reference to that object. Here's one way you could do it.... Set your Elevator Button Ref "Expose on Spawn" to true.

Then go find your elevator door that you've placed in your level.

Click on it, and then you'll be able to select which button you want to use directly on it.

[honest raven]

awesome thanks for that

[dawn gazelle]

It's one of the things you need to wrap your head around when dealing with object oriented programming... You need to specifically get a reference to the object you want to manipulate.

[honest raven]

what if i drag off the blue pin of the Set and do Get Elevator Button?

or is that too generic

[dawn gazelle]

The set node is only for setting the value of the variable.

[honest raven]

ah ok

[dawn gazelle]

If you have nothing connected on the left side of the set, you're basically saying the value of the variable is nothing, and then by dragging off of it on the right, you're saying get that value of nothing 😛

Another example of how you could get a reference across, is how you're doing an overlap - that "other actor" pin is giving you a reference to something external, and by casting it, you're finding the specific object + its actual class, so you could manipulate that object.

[honest raven]

I think i gotcha. So now i can go into the door actor in the editor and under default choose ElevatorButton from the drop down and now it has a specific reference for that variable im using. Very interesting.

[dawn gazelle]

If the cast succeeded of course

Yes

[honest raven]

so im sending that data to the variable. all the reference is, is saying hey some sort of object data is going to be inside this variable. but it doesnt know what object data, just that it is a object reference type with the name ElevatorButton

so i have to provide the rest of the information to it with the actual data of what the object actually is. in this case by choosing elevator button in the drop down that comes up after the expose on spawn being checked. letting me add data to that variable

i guess the part that threw me off the most was the fact that when you created that reference variable you could Get the object variable and then get the other variables that are inside the referenced object. So i was like wait you know what is inside the object but not what the object is? WUT? lol

[dawn gazelle]

not with the name ElevatorButton, the class of ElevatorButton.

[dawn gazelle]

Correct

[honest raven]

So on the left blue pin of the Set, is there something I can do there to tell it what to use as the main reference? Something similar to choosing Elevator Button in the drop down in the editor

Or use that pin to get the actor I'm going to be using. Sorry my terminology is still bad lol

[dawn gazelle]

Yes, lots of different ways of getting a value that you could set into an object reference, but the thing is, you have to have a way of getting that reference.

And I gave you one example already - the Get Actors of Class and then looping through them or getting a specific value out of the array, though this way is not ideal for what you're doing.

You can get a reference through overlaps, like I pointed out above, and then cast to your appropriate type, but again, not what you're looking for.

[honest raven]

So this?

[dawn gazelle]

Sure, but that'll only ever get the very first one it finds and it could be any of them in the level.

[manic knot]

@dawn gazelle Thank you I'm trying that now

[honest raven]

gotcha gotcha, this is a very general, one actor reference. which is bad for later when i have like 5 elevator doors in my level with various other buttons

[dawn gazelle]

Correct. how you have it exposed right now is probably the best solution if your button is separate from your elevator object.

That way you can set it in the designer to reference the button you need.

[honest raven]

just getting the basics in my brain of how this is all working within the engine

very cool, awesome. its finally becoming clear on why this never worked before haha

i kept thinking the creation of the variable, using the name of the other actor as the variable type, was the reference

[dawn gazelle]

Nope, just the name of the variable as you want it in that blueprint + you're defining the class of it, not the reference to the object in the game.

[honest raven]

I like it when progress happens lol. So thanks a ton. Now to get this all plugged in and working right. Should be fun

[olive sedge]

I have a widget and on that widget an onclick. In the event I return handled but my playercontroller still picks up the click. Anything else I need to do to prevent the bubble?

[dawn gazelle]

You using the OnMouseButtonDown function?

[manic knot]

@dawn gazelle Aw damn so I'm not sure that will work in my case, as I'm trying to disable an action when the player is ragdoll and in the air, which I believe switches the movement mode to "none" whether on the ground or not

[olive sedge]

@dawn gazelle it's an image widget inside my widget and I have bound OnMouseButtonDown, yes

[dawn gazelle]

Is the image set to not-hit testable?

[olive sedge]

@dawn gazelle can't find that setting

[dawn gazelle]

Doesn't matter - I seem to get clicks going through only if I click rapidly, which would be considered double-clicks.

Yours is always going through?

[olive sedge]

I'm thinking maybe the PC gets it first, gonna check

[honest raven]

is there something like EventTick you can use that doesnt run the code every frame but you could tell it like to check every 5 seconds or something. Like a timer? set timer to 5 seconds and at the end it executes?

[dawn gazelle]

Yep, set timer by event

[honest raven]

looping around

[olive sedge]

@dawn gazelle appearently the image eats the button down but the button up triggers on the controller

released

@dawn gazelle having that ignored would be incredibly hacky interaction between the widget and the player controller

Actually, I'll just set a bool on pressed and if it's not set, I'll ignore released

[cold raft]

What is the best way to grab all the columns of a DataTable for loading into a widget? I am currently doing this, but it looks like it hits the datatable in each for loop. Will that cause performance issues?

[maiden wadi]

@cold raft This was actually one of the first things I learned to do in C++. Populating an array from a datatable is immensely faster in C++ than it is in blueprint because of the way it's structured. If you can, I'd recommend making a simple library function or whatever that can populate an array of structs from your datatable that you can then use for the UI.

Realistically though, it depends on how often you call it. If you do that once, I wouldn't bother changing it. If you read from datatables often, it's worth it.

[honest raven]

Lol had this code working but didn't like that I had to use EventTick for it to work right so I messed around. Now I can't get the code to work anymore even using eventtick lol. Gotta love when you break stuff.

[maiden wadi]

@honest raven What are you having trouble with?

[honest raven]

Oh just some newb code I had running where an elevator door open when hitting the button which was a separate actor. The button code trigger a OpenDoor boolean to go true which I then added to the elevator code to trigger the doors to run the open animation. But only event tick would keep pinging the branch to check if the boolean was true. Now for some reason it's never triggering right. Probably butchered that explanation lol. I'll figure out what I did I'm just tired

[maiden wadi]

For an elevator, it would be best to use timelines. Or for more complicated implementations, enable or disable tick based on events. Elevators are kinda fun. Specially when you have to consider multiplayer implementations.

[honest raven]

This is day 3 for me so I'm just learning how this all works. Damnit it worked a moment ago lol. Guess I messed around too much. I used timelines for the door opening " animation ". Doors open, wait 2 seconds and then close back up. I'm gonna add a " if player is in between doors don't close " thing later but for now gotta figure out how I broke the opening altogether lol

[cold raft]

Cheers for that - I will flag this as needing to be replaced. For now it is fine as it is only loaded when the player logs in, or gains an achievement, so probably not going to get refreshed a lot.

[maiden wadi]

@cold raft It might not matter that much then. But I did some rudimentary testing with blueprint versus C++ with datatable extraction. A datatable of about a hundred items that took almost 50ms in blueprint to fully run into an array was cut to roughly 3ms in C++. Over 90% difference of compute time, it was a pretty brutal example of Blueprint vs C++. At the time I was constantly polling a datatable for information about items via an ID, because my inventory is just a list of amounts and an ID. I noticed with larger inventories it was destroying my framerate. Before I switched to C++, I tried simply dumping the datatable into an array that the inventories could poll rather than the datatable, which worked perfectly after the initial startup. That was what was taking almost 50ms, the same exact functionality that just returns an array of the same thing in a C++ BlueprintCallable function was 3-4ms in the profiler.

[cold raft]

That's awesome info! I will load the DataTable to an to array and query that for now. [when a programmers says "for Now", of course that means leave it like that for many, many years until users scream about performance and leave it for the interns to fix]. 🙂 Thanks again for your help!

[scarlet ibex]

does anyone know how to make this enemy ai jump over the barrels/boxes?

ive already made blueprints for the ai to chase the player but the enemy will always get stuck

[olive sedge]

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

oh the dread! :>

[maiden wadi]

@scarlet ibex Really depends. There are a couple of different ways. Some games just make the AI query if it's stuck and it will jump if it is. Other games specifically create nav points for the AI to run to and jump to specific locations.

[dawn gazelle]

I get that every time I compile C++..... It's how I know my compile succeeded XD

[olive sedge]

😆

I've resorted to closing the editor to compile

but that's not even what's crashing the thing. I do an RPC client -> server, that triggers a multicast event dispatcher and BAM! Fatal gunshot wound to the editor

but only if I have a breakpoint on the mutlicast handler 🙈

[scarlet ibex]

which way would be easier to do so? i do not have much experience with blueprinting and coding

i also cant seem to find any tutorial that work out for me T^T

[maiden wadi]

@scarlet ibex If your level never changes, and you're not used to writing logic, I'd probably say NavLinks. This video seems to cover it okay. Skimmed through it quickly. https://www.youtube.com/watch?v=wW4t5QxOQaE&feature=youtu.be

[scarlet ibex]

alright thank you

[queen lichen]

so after some research and testing, turns out the score is blueprint is working but this isn't changing the score 0 to 1. how would anyone get this one to work properly? I've seen vids of using target score but i don't seem to have it for some reason.

[maiden wadi]

@queen lichen Not following what you're trying to do? You're trying to make that function return 1 instead of 0?

Or are you trying to get the score that is stored in a specific pawn to return that?

[queen lichen]

@maiden wadi mainly trying to get the score go from 0 to 1 once the ball goes through the green wall.

[maiden wadi]

Is the ball your controlled player pawn?

[queen lichen]

yes i control it with my mouse

and its a pawn

the wall is an actor

[trim matrix]

Hello guys, I work on change nickname function but it doesn't work

any help?

when I change to this name, it doesnt confirm it and set on the old name

[cold raft]

get rid of the SET in button confirm - you have already set the text, but there you set it to null

[trim matrix]

okay

so if I remove the node it will work?

I removed it

still doesn't work

@cold raft

[cold raft]

Might be Text committed - try updating your variable from the on Text changed instead

@trim matrix - or you could just set it once when you click the button, probably not needed to update the variable on each keypress?

[trim matrix]

so text commited to be empty?

[cold raft]

Yes, you shouldn't need all 3 events - try from the on textChanged first to update the variable and see how it goes

[trim matrix]

same shit

doesn't work again

[cold raft]

In your editor, right click the SET box and choose "Add Breakpoint" - then run the game and type something in. The game should stop when that code runs and you hover the mouse over to see the value of 'Name' - this should be what you typed (the first letter at least). Also, are you getting any error messages when you run that code and stop the game? @trim matrix

[trim matrix]

yep

I don't run erro messages

I ran when I had this code:

[cold raft]

@trim matrix Thats good - it proves you are getting text from the textbox. After that you should be able to access the variable Name from your player controller - post the code you use to do that (the Set player name you posted isnt connected to any event so it wont run)

[red portal]

can anyone help me with my healthbarUI? It works fine until I take damage (10) and then it just drops all the way to 0 instead of the 90% it should be showing

[olive sedge]

@red portal are you using progressbar?

[cold raft]

Can you post the Blueprint where you change it? - might be it is expecting 0 - 1 but you are giving it 0 - 100

[red portal]

Im dividing it by max health (100) so I dont see why it would be getting values higher than 1

[olive sedge]

It's getting stomped, you're dividing integers

Convert to float before you dividw

[red portal]

same thing happening

[olive sedge]

https://docs.unrealengine.com/en-US/BlueprintAPI/Math/Conversions/ToFloat_integer/index.html

You're doing a conversion to float, then back to int

Remove the truncate and connecto to divide float by float

[red portal]

It's just that I've seen it work with my exact code, so although converting it to a float would work, I'm just confused as to why mine isn't

[olive sedge]

Because 40/100 =. 4

But an int cant have decimals so it gets truncated to 0

Or rounded, not sure

[red portal]

like this?

[unique hollow]

don't use bindings

for health that is

use an event driven UI system

bind calls every frame

[red portal]

part of my course mate 😦

[unique hollow]

you want it to only call when needed

it's way better when you use events instead of bindings because you save performance by only updating the health bar when it's needed, and not every frame

it's extremely simple to do too

I have a progress bar for this too

the dispatch calls every time the player takes damage

[full wind]

anyone knows how to access an montages metadata

cause dang it i wanna put info in those things xD

[trim matrix]

so you want to move this code to text changed?

but I got these errors

bruh

[maiden wadi]

Your blue variable is empty. It's not pointing to anything.

[trim matrix]

you mean hud reference?

[maiden wadi]

Yeah.

[trim matrix]

hmm

so?

[maiden wadi]

So you can't call functions on empty pointers. It doesn't know what instance of that object to run the function on.

[trim matrix]

okay

like I need to set it to have something in it and then to get it and set the function?

[maiden wadi]

Is HUD another widget that's on screen?

[trim matrix]

yep

I have hud

and in thud widget I have fuynction to set the player health

and his name to 123456

[maiden wadi]

You need to save a reference to it somewhere when you create HUD, then this other widget can get that from where you save it.

[trim matrix]

yeah okay

on event tick in the event graph in change nickname widget?

still doesn't work

hmmm

[unique hollow]

I've been trying to replicate "view rolling" from Black Mesa (the Source game) into UE4 but not sure how to exactly do it, here's a video of it (when you move left, your camera slightly turns left, when you move right, your camera slightly turns right)

[olive sedge]

@unique hollow on move left, put your roll slightly to the left and the same with right, then interp between them

[unique hollow]

yes problem is how would I do that

I don't think my movement allows for it

I'm not exactly sure for how I'd check for axis movement pitch

I only have moving forward and right

with two keys assigned to both with + and - pitches

[olive sedge]

just save your axis value

-1 would be left and 1 right or vice versa, there's your roll

[unique hollow]

so would I have a custom event that gets triggered every time I move right or left, then checks an if statement (branch) for if my axis is a certain value, and if yes, roll in that direction?

[olive sedge]

could do it with an event dispatcher, yes.. or just use your input event and save the axis

[unique hollow]

yes that's what I plan on doing

[olive sedge]

so.. I got a problem too. My NPCs are trying to walk somewhere and trip over each other.
LogCharacterMovement: BP_Quad_C_3 is stuck and failed to move! Velocity: X=599.00 Y=28.00 Z=0.00 Location: X=-932.17 Y=-1236.86 Z=90.15 Normal: X=-0.56 Y=-0.83 Z=0.00 PenetrationDepth:0.589 Actor:BP_Quad_C_0 Component:CharacterMesh0 BoneName:weapon_l (4 other events since notify)

I tried to show the nav mesh with show Navigation but I get LogNavigation: Warning: No NavData found when calling UNavigationSystemV1::VerifyNavigationRenderingComponents()

these are my runtime settings: https://i.imgur.com/l4RWuzo.png

any idea?

[somber quail]

ight i need some help this is just not working so i am trying to make a switchable build mode but it just dose not work what so ever when it does work sometimes it does not place a block and sometimes it does
then when i add the brake switch (the destroy mode) it then just destroys and dosnt build
even when set to build
then when i remove the build mode switch and just make it perm build it is fine

[unique hollow]

well the log is clearly not finding navigational data, are you sure you built navdata correctly?

[olive sedge]

@unique hollow yes. it shows up alright in the editor and they move as they're supposed to but the mesh doesn't seem to update with my characters moving around

[unique hollow]

that's because the navmeshes are precomputed as far as I'm aware meaning that they don't update dynamically

[maiden wadi]

You need to enable that in the project settings.

[olive sedge]

https://i.imgur.com/l4RWuzo.png

isn't it this?

[maiden wadi]

For dynamic runtime generation, yeah. Trying to see what that error is about.

[unique hollow]

okay so

uhh

this not work

using print string I checked that the axis values are correct

and are set to -1.0 on left and 1.0 on right

[somber quail]

what are you trying to do

[unique hollow]

I'm trying to rotate the camera in a certain direction

when moving left or right

https://cdn.discordapp.com/attachments/221798862938046464/798140274458624051/2021-01-11_10-22-12_Trim.mp4

like this

[maiden wadi]

@olive sedge You cannot see your nav mesh at all using Show Navigation?

[unique hollow]

rn I'm just testing to make sure it works in the first place

[somber quail]

where it says sequence just change it to a multi gate and set it to loop

well i mean that is probs not a propper way of doing it

but it will do the trick

(maybe)

[olive sedge]

@maiden wadi no, it doesn't show up at all. I do see it in the editor when I hit P tho, looks fine

and the navigation works as intended. Just not updating with the characters moving around

[unique hollow]

but since the input for moving right and left is an axis input, it should be constant

therefore there's no need for it to loop anyways

I think

[olive sedge]

@unique hollow not sure about the rotation. does it work without input, just like on beginplay?

[maiden wadi]

You could try to force rebuild it really quick by deleting the recastnavmesh, then nudge your NavMeshBoundsVolume just a little. Seen it fix a few issues like that.

[olive sedge]

or tick?

@maiden wadi ok, will try once I get my editor back up 😓

[unique hollow]

nope

[olive sedge]

I enabled landmass plugin but don't know how to build the thing from source

[unique hollow]

doesnt work on beginplay

I'm not sure why either

[olive sedge]

@unique hollow tick?

[unique hollow]

nope

[olive sedge]

I don't know how else to roll the camera.. gotta work on that first I think

[unique hollow]

hmm

[maiden wadi]

I'd probably just do it based on velocity. Check velocity based on character's local space and lerp a roll value back and forth based on it.

[unique hollow]

I'd rather not

the velocity isn't always the same

I prefer it being set in stone

might be because of how my player code is handled

the current player character is a child of a C++ class that contains special code that can't be done through blueprints

but it should only really affect movement

I might wanna move with this to C++ channel

although i doubt this is the problem

as these are the two only mentions of camera in the code

and all they do is set some basic values and collision responses

therefore shouldn't really be a problem

[cold raft]

you are almost there - replace the "Set Player Name" with "Get Player Name", and from that do a "Set Text" which passes the Name text to it

[somber quail]

,_,

i guess no one has a answer to my problem

[unique hollow]

well

your question is pretty ambiguous

[somber quail]

wat

[unique hollow]

it means

[somber quail]

oh

[unique hollow]

not very precise

[somber quail]

ok

yea

i just googled

welp

here is it copyed and pasted but ill tweek it

ight i need some help this is just not working so i am trying to make a switchable build mode so a mode where you place buildings and a mode where you destroy the buildings

but it does not work

it breaks by:
if i remove the switch (the key that switches the modes) it works fine i can just build (no destroy)
if i then add the switch (but no destroy added yet) then sometimes it will place the buildings sometimes it wont
and if i then add the switch and destroy mode then it wont let me switch it will only let me destroy

[unique hollow]

show us the code

and what do you want to achieve

like

oh

nvm, got it

but still code needed

[somber quail]

there is one with the switch (bottom)

and one without (top)

rn i have it set to the bottom code

[maiden wadi]

@unique hollow Ah. I think I might have realized the issue. If your FPS is set up anything like mine, your camera or spring arm uses control rotation, you'll want to affect the roll on that instead of the camera itself.

[unique hollow]

ohh

[maiden wadi]

Top, instead of the bottom.

[unique hollow]

gotcha

I'll check it out in a sec

[unique hollow]

It worked!

Thank you

I am deeply grateful

[somber quail]

ok this is annoying me but below the event tick there is a camera tilt slider and it is slitely off place

[maiden wadi]

Does it make you a little.. tilted?

[trim matrix]

Anyone know why AIMoveTo Doesn't work when the actor is spawned in from the level blueprints?

[somber quail]

why just .... why

why must you hurt me in this way

[maiden wadi]

I'm just a little.. off centered.

[somber quail]

,_,

no

[cold raft]

search for Auto Pocess AI = change from Placed in World to "Placed or Spawned"

[maiden wadi]

Also make sure you're using SpawnAIFromClass, and not SpawnActorFromClass.

[trim matrix]

My heroes!

[unique hollow]

so, this works

[maiden wadi]

@trim matrix The bottom node will do everything that the top execution line is doing.

[unique hollow]

but now I'm not sure how to lerp it

[trim matrix]

@maiden wadi Right, got it thanks fam

[unique hollow]

so what would I do to make it interpolate between camera swings

so it's not snappy

using lerp is my weak point, I rarely ever use it

so pardon me

[small plover]

Hi, so my character has the "Orient rotation to movement" set to true and the "Use controller rotation yaw" set to false. I move it around using cpp with ```cpp
AddMovementInput(cameraRelativeMovement, 1);

But when i move, the rotation twitches like in the video. I don't know how to solve this, has anyone any idea? thx all

[trim matrix]

this way?

[somber quail]

yea i am still havin this build problem

[maiden wadi]

@unique hollow The one I posted earlier was working fairly well I thought. I tried it without the extra variable, but there was some bug with moving left and turning right at the same time that royally messed up the camera. The variable seems to negate that.

[somber quail]

stuff it this is not going to be a building game its gonna be some sort of farm game

seeing i just made little wondering robots

[maiden wadi]

@unique hollow This on the other hand, does not work, bugs out badly.

[somber quail]

hand

[cold raft]

No, check your previous screenshot - you need to go from HUD > Get Player Name > Set Text . And in the Set Text, then you pass the Name variable you set previously

[unique hollow]

hmm

https://cdn.discordapp.com/attachments/221798862938046464/798158097990287360/unknown.png this happens when i interpolate from the current rotation (f.e i am moving left or right) to the default rotation

and set that as the current control rotation when my speed is 0

[maiden wadi]

@unique hollow Is this being called from your move right/left axis event?

[unique hollow]

yes

[maiden wadi]

Try something like this.

[small plover]

nobody for this ?

[maiden wadi]

Looks like it's overcorrecting it for some reason.

[trim matrix]

I can't get name from the HUD

[maiden wadi]

@small plover Are you doing any other form of rotation on this actor? Cause that's not normal with only OrientRotationToMovement. Also what Z(Yaw) value do you have set for that?

[small plover]

No no other set rotation except for the camera spring arm, the Z axis may be a good lead i'm going to check for that quickly

Its not the Z thing, it's always at zero

I guess i should go in the cpp section for this but here is my code

// Apply camera relative ground movement
            FVector cameraForwardOnPlane = FVector::VectorPlaneProject(Camera->GetForwardVector(), FVector(0, 0, 1));
            cameraForwardOnPlane.Normalize();

            FVector cameraRightOnPlane = FVector::VectorPlaneProject(Camera->GetRightVector(), FVector(0, 0, 1));
            cameraRightOnPlane.Normalize();

            FVector cameraRelativeMovement = InputMovement->X * cameraForwardOnPlane;
            cameraRelativeMovement += InputMovement->Y * cameraRightOnPlane;
            
            GEngine->AddOnScreenDebugMessage(-1, FApp::GetDeltaTime(), FColor::Green, FString("Z axis: ") + FString(FString::SanitizeFloat(cameraRelativeMovement.Z)));

            AddMovementInput(cameraRelativeMovement, 1);


            *InputMovement = FVector::ZeroVector;

i map the camera vectors on the horizontal plane and then multiply them by my input to get the movement relative to the camera

the Debug message was to check, the Z axis is always at zero

[small plover]

so i dont think thats the problem

[maiden wadi]

I meant for this. The Yaw rotation amount applied to that.

That seems like a rather complex way to get the movement direction from the camera direction.

[small plover]

Oh sorry, i have 360 but changing it doesnt solve the problem i've tried with different values. it seems if the value is low the twitching gets smaller but its still there

[steep verge]

guys i am struggling a bit with a problem. Every time i spawn in my level the animation for some odd reason freezes but when i move my cursor its fine. This demonstration i printed out the skeletal mesh head bone rotation just to show the animation freezes. any ideas?

[small plover]

and i know its "old" code i wrote 3 month ago when i was just getting started with ue4 i'll have to get back to it sometimes. i should mention the bug with the twitching just appeared and it used to work fine

[maiden wadi]

I normally just use the camera's world rotation and zero pitch out and then turn that into a direction vector.

Not sure about the twitching then. But it definitely looks like either something is overcorrecting constantly, or two things are fighting for the rotation.

[cold raft]

@trim matrix - this is what I meant about Getting the Object, then setting the text IN that object

[trim matrix]

aha okay

[small plover]

yeah that's probably it. i'm going to investigate more. the worst part is: i had this exact same bug when i first started and then fixed it and then my character blueprint got corrupted because of a known ue4 bug and i had to recreate one and now i have the same bug and dont remember how i solved it the first time. But its definitely in the blueprint because the code is the same as before

[split bridge]

is there any ways to connect UE4 camera to OBS?

[fleet nimbus]

Hi! Uh, excuse-me I would have a question, I try to load a scene (via commandline), and it works just fine, the thing is that.. the loading screen doesn't disapear

[keen seal]

Hey, why does my top down character spin endlessly in place?

I didn't add any blueprints for him to do so.

[worn nebula]

Hey guys, how can I make a head bob just when the player is in a certain volume?

[solemn parcel]

So my player character can spawn an actor wherever he wants on the map, with no limit in number. I need to setup each of these actors to have their real time coordonates, to be able to limit their spawn to a certain limit around each already spawned actors. How can I go with this ?

[gritty elm]

Hi, do you have any idea for smooth mouse movement

i have basic camera pawn, i want to rotate my camera with my mouse

but smooth rotation

[solemn parcel]

@gritty elm Camera Lag probably ?

[gritty elm]

should i need spring arm?

in my pawn

[solemn parcel]

I don't think so

[sonic cipher]

how can i avoid the cube to turn when i hit wall then release please ? https://gyazo.com/364aa5555dd3a38eb9513b4991e75127

[woeful dawn]

Hi, I was just wondering if anyone has an idea on how to make the time travel mechanic from titanfall 2's Effect and Cause mission. I was thinking u make two maps, put one above the other and when the player hits time travel button, warp them to the other map. Is the a good way to do it?? Also, hope everyone is having a good day :))

[small plover]

that is the exact way respawn did it 🙂

[last walrus]

I think it should be done with splines in 1 map
loading 2 maps at the same time is not the best idea

example of what I imagine: when your char moves you can make spline leading his way and when you want to move backwards just set his position to first spline checkpoint (of course you should delete old points of spline if your time travel has a timer)
or if you want insta teleportation without smooth movement - you cant just record points in space

[ancient topaz]

Guys, tell me how to make that the character does not rotate around its axis with the mouse?

[orchid garden]

to disable the turning of the cube while your carrying it just disable physics on it after you pick it up. that should stop it from turning when it bumps into a wall, then just enable physics on it again after you drop it. far as it turning after its dropped, not sure.

[sonic cipher]

thanks but then if i disable physics it wont move

[orchid garden]

sorry i was assuming you were attaching it to the actor after pickup.

maybe temporarily increase the mass of the object?

i.e. record its current mass, then set its mass to some ungodly amount like 20,000. that should stop physics from turning it, donno if that would interfere with how you move it on the character though.

[solemn parcel]

Does that ForEachLoop calculates the GetActorLocation of each of the ActorsOfClass in one loop ?

[worn nebula]

How can I make this blend? I've tried using Set View Target with Blend and making the cameras under a child actor but I still can't connect the child actor to the New Target node

[zealous moth]

@worn nebula

[worn nebula]

Yeah I said I tried using that, but my child actor wasn't connecting. I found out you need to bring in your child actor, then get child actor then it connects -.-

[zealous moth]

child actor variable or the actual child actor?

[worn nebula]

Like this, didn't realise it had to be like this

[orchid garden]

okay this may seem like a really silly question... but... is there a simple function to detect if the actor is a player or or not?

[dull gale]

When using MultiLineTrace, does the array of objects get sorted by distance? e.g. if I put a "For Each Loop" after the Trace, does it go through each hit in order from closest to furthest?

[proud hull]

Child Actor can be confusing like this. The left one is a reference to the "Child Actor Component" which would be attached to the actor you are currently working out of. The right one is the actual "Actor" being attached. Imagine the component simply being a container which is holding the actor.

[worn nebula]

Ah, thank you!

[proud hull]

They are added in the order they hit, so it would go in order by distance as well.

[nimble talon]

I have been reposting this question for some time now

[dull gale]

perfect, thank you

[orchid garden]

sounds like something that would be better answered in #legacy-physics

[honest raven]

Getting frustrated. Can't figure out why this blueprint is not detecting the boolean change of another blueprint. Have a confirmation print string in one blueprint that spits out when the end boolean gets turned to true. Plug that boolean into another blueprint attempting to use it in a branch where True starts an animation. But despite the string still being printed, which means the boolean has changed to true, it doesn't recognize that change in the other blueprint so the animation isn't playing.

[nimble talon]

Oh

Okay, thanks

[proud hull]

You can also test it to verify, just print out distance instead:

[orchid garden]

sry that i can't be much help with it, physic objects drive me nuts... ones placed in the level seem to react differently then ones spawned in the level.

[nimble talon]

That sounds wonky

[proud hull]

Can you show how you are currently giving the cube movement?

[nimble talon]

That’s the thing

I’m not

[honest raven]

using the pressing of E as the trigger to check the branch. works when it is set to False to continue on, but True is never triggering

[nimble talon]

I scrapped forward and backward movement for now

[orchid garden]

yeah i know, had been fighting with it for awhile for some items, so i decided just to spawn them in rather then place them.

[nimble talon]

hmm

[dull gale]

will try, working on a bullet penetration mechanic, still wondering if I should make it based on penetrated material thickness but that'll cause a few more headaches

[nimble talon]

So when you spawn them in, what exactly is different

[orchid garden]

how the mass of the objects is being processed by the engine (4.25), when placed they seem to be 10x lighter then when spawned.

[proud hull]

Instead of multi line trace, you might even want to look into doing multiple single line trace calls. Usually bullet penetration involves changing the trajectory and velocity after each hit.

[faint pasture]

Just don't use child actor components, they suck.

[orchid garden]

i.e. when placed, a 200 kg object reacts as if its only a 20kg object, but when spawned it reacts as if its a 200kg object.

[nimble talon]

Oh.

Hmmmm

[dull gale]

Might look into that later, right now I'm under a big time constraint so I want to focus on the essentials. Thanks for the tip though, I'll definitely rework this later and might include that

[orchid garden]

sooo back to my seemly silly question... is there a simple way to detect if the actor is a player or not?

[faint pasture]

I made a projectile movement component that worked like this.

Projectile mesh has NO collision.
Each frame, do this:

1. Update projectile velocity (new = old + acceleration * timestep)
2. Trace from projectile location to next location (new = old + velocity * timestep)
   2a. If hit, do hit stuff, if it'll penetrate, update velocity, add hit actor to ignore list.

I do it without a projectile mesh, just particle system for trail.

[faint pasture]

Is a player what? Pawn, controller, state, what?

[orchid garden]

well for instance.... things players can possess... only wanting it to fire off certain functions if its player controlled, and other functions when its not player controlled?

[faint pasture]

Is Locally Controlled

[orchid garden]

ah ty @faint pasture Adrial 🙂 knew there had to be something simple 🙂

[nimble talon]

I’m attempting to show forward and backward movement

[dull gale]

That sounds awesome, might try something like that in the future as well, but right now I'm loving playing with "lasers" too much

[proud hull]

Is Player Controlled will work for multiplayer while Is Locally Controlled only checks for local controllers, so split-screen maybe.

[orchid garden]

"pew pew pew" ... 3 days later ... "i need to stop playing with lazers and get this project done... " "pew pew pew"

[faint pasture]

The good thing is that if your velocity is high enough, it's effectively a laser. It's basically a velocity/timestep length line trace per frame.

[orchid garden]

yeah i just need it for local stuffs 🙂 but ty for the tip 🙂

@dull gale hehe i tend to do that sometimes ( start playing with something ) and forget what i was working on in the project lol 😉

[dull gale]

Doesn't making projectiles too fast have weird results with physics like ignoring collision? In your case there wouldn't be any collision but maybe it would skip a hit?

[dull gale]

My problem is having a specific goal, realising I can do more, wanting to do more, then realising I don't have time for that

[orchid garden]

theres always time :D, unless its a schooling project... but... can always come back later and make it better 😄

hi all, can i ask a hand on a issue that i haveon open and close a wiget already created with a keey?

unfortunately i dont know how to use if value on unreal blueprint

[orchid garden]

branch?

[sharp zealot]

i wanna to check if visibility of a widget is true and if is true i wanna make it hidden, if false i wanna make visible

😦

for now i can make it hidden with key I

[orchid garden]

from the widget reference - isvisible?

[sharp zealot]

with set visibility

[orchid garden]

loading a project that i got widgets in so i can make a sample 🙂

[sharp zealot]

thanks 🙂

[orchid garden]

actually... i think i got a little hide/show thing already done in this one...

[sharp zealot]

just for to understand, IF is flipflop or branch?

[dull gale]

that's exactly this situation, if only I didn't have to write a report afterwards 😄

Hi, I need assistance with Spline Meshes. I made a spline where I want to populate a mesh but the scale is off.

I would be very happy if someone could tell me, why the scale is off and if there is a good way to scale it.

[orchid garden]

top is flipflop, bottom is branch example:

what is HUD ui?

[orchid garden]

its a reference to my widget

[honest raven]

While debugging I see after each InputAction I get that confirmation that the Pressed is executing. But as soon as I enter a box collision it is no longer registering the Pressed anymore. Just dies. Anyone know what could cause that?

[sharp zealot]

how can i get it of my HeadsUpWidget?

[orchid garden]

my hud widget contains all the things that are visible while the player is moving about:

and i hide / show certain widgets in the hud widget (like the info panel above the quickslots) when needed / not needed

[sharp zealot]

i have same variable created in gamemode and with that i set widget visible on starting

[orchid garden]

your hud var = my hud ui var

[sharp zealot]

ok but from blueprint of character i donw know how to call gamemode hud variable 😦

[orchid garden]

sense its stored in your gamemode you'd get a reference to game mode and pull a pin off it and type 'get hud' and it should show up in the list

[sharp zealot]

as this?

[orchid garden]

with your original code, this should work, just make sure you have the widget class set to your heads up display:

(i had to use a different key on keyboard as the other is assigned to something)

[sharp zealot]

it works 😄 really thanks 😄

Get game mode >get hud object reference > set visibility

[nimble talon]

Does anyone know how I can quickly capture videos on my pc

[weary jackal]

It will save the for loop clocks

[orchid garden]

not class, just 'Get Hud' should appear near the bottom, will be blue when you add it.

[nimble talon]

👆🏾

I am trying to show an example

Err, I don’t do this often

[weary jackal]

There are applications for recordings like obs studio, xbox gamebar....

[orchid garden]

obs studio is going to make the video too large to share on discord so you'd have to upload it to something else and share a link.

[nimble talon]

For some reason it is not letting me record with the game bar

Oh, now I can

I like how it says the name of my game lol

[proud hull]

OBS works just fine, just change your output settings.

You can lower quality to make smaller videos.

[orchid garden]

its kinda overkill for using for just discord shares.

[faint pasture]

That's exactly it, there's no actual physics. The faster the projectile velocity, the further it traces per tick.

[orchid garden]

wtf.... discord keeps shutting itself... this is getting annoying...

[proud hull]

Funny thing is, Set Visibility node actually doesn't even need for loops before it as it accepts arrays as the target, hehe.

[nimble talon]

Okay

I am on PC now

Here it is

[orchid garden]

beats discord with a stick quit restarting!

[nimble talon]

uh

I keep inserting it

Nothing's happening

ummm

What do I do

[orchid garden]

so.... i named a project RNG, as im working on a rng system piece.... every time I launch that project, discord restarts.... any other project, no problems, just the one labeled 'RNG'.... why???

[hearty moss]

are you dragging it onto discord or are you clicking the + on discord to add it?

[dull gale]

hmm, I'll definitely take a look at that, last time I did shooting projectile based I kept running into physics issues, even when I didn't use colliders so I became a raycast/linetrace preacher

[nimble talon]

I am clicking the +

[hearty moss]

try dragging it on

[orchid garden]

try just dragging it on to the discord window

[nimble talon]

I just tried dragging

File size too powerful...

Oh, come on

[orchid garden]

video is too big
