Health and maxhealth driven by other stats

Keeping them all in one comp keeps you sane.

So youd have functions for GetMaxHealth

[steady night]

well im way to deep into it now x)

oh so instead of setting the max health to a value i will call for the function each time instead ?

thats complied the max halth ?

[gentle urchin]

Which simply returns

(Level * HealthLevelScaling) + 
(Strength * StrengthHealthScaling)```

[steady night]

yeah i guess thats a better way

[gentle urchin]

Keeps you sane and consistent

[dark drum]

move the flashlight comp onto the scene root and it should give you an option to make root.

[steady night]

yeah easy to adjust also

[gentle urchin]

Yepp

And less shit to replicate

As max health is simply a product of the other stats

Basehealth and scaling values are static (presumably)

So you only need to replicate current level and the related stat(s) value

[steady night]

yeah

[north lynx]

Oh, right, that works

[north lynx]

I have one more question to you if you don't mind

[dark drum]

sure

[pulsar pulsar]

So I'm having the issue where Trace Actor is being set to Null (ultimately giving me "Accessed None trying to read property" error) when i'm not looking at a object inherited from the required class for Trace Actor to be set. I kinda want it to be this way because Trace Actor should be null when I'm not looking at the specific object but I want to get rid of the error aswell and I'm not sure what I should do

[north lynx]

I must to know which item set to invisible for player, and of course I need it to be a var that I can update

I need here to get this var to set the visibility to off, when the item is dropped

I tried to do something like this, but I get an error

[pulsar pulsar]

Or rather, I'm not sure what I should do about it when I'm not looking at an Actor of required class.

[north lynx]

I don't want to set the visibility for all the items without any purpose

[pulsar pulsar]

nvm, fixed it lol. I should have payed full attention to the message log 😅

[graceful forum]

Is it normal that if I set my widget visibility to Collapsed, my WidgetComponent's tick also stops working?

[supple osprey]

I want to extend an Event which is inherited, so far so good, but in the overwridden event I want to add an input pin (in the given example fading curve)... Do you know how or if this is even possible?

[versed sun]

You can Right click the Parent: Apply Effect and "Expand Node"

Then make any changes as needed

[ember hazel]

How can I make it so that the actors are destroyed with a delay from the one before it.

Right now they all destroy at once

[thin panther]

Use a looping timer

Cache that array in a variable, then each iteration of the timer check if the index is valid access the index, delete it, increment the index.

If the index is invalid, clear and invalidate the timer handle

[gentle urchin]

Or

Set lifespan

Done

Set it to the value of the index

https://forums.unrealengine.com/t/hide-active-widget-if-left-mouse-is-clicked/134657/6
Can someone help me on this topic? I want to achieve this.

[tropic bison]

When I disable the spring arm's "Use pawn control rotation", my camera wildly spins right or left depending on where the mouse is, I don't think I have anything in my code to act like that, or am I tripping?

Intention is to have camera zoom in and out, but I want to use offset for spring arm, and cant tick "use pawn control rotation" if I want to achieve that.

Edit: Answered

[willow gate]

Hey all. I'm working on an inventory and it's functioning fine. I am, however, getting runtime errors saying that "Accessed None trying to read property CallFunc_Array_Get_Item" in my FindEmptySlot function:

Any ideas?

The "Items" variable is an array of data assets btw.

[fleet lichen]

Hi, I am trying to practice using blueprints but am out of ideas about what to do. So I want to ask if there is some website or something with challenges to make with blueprints.

[willow gate]

I think I know why it's happening I just don't know how to fix it. The array it's pulling from is empty to begin with. They are just blank placeholder primary data assets and no specific asset is assigned. The size of the array just determines the player inventory size. So when it's trying to get the array element, it's not finding anything.

[gentle urchin]

Pro tip: instead of saving local variables, you can simply return mid-loop with the index

If branch true -> return current index

Makes the code look clean 😄

Early return is nice

Also. Check that the elemnt is valid before pulling data

[spice shell]

Anyone know what Blutility function I could use to trigger a 'Play in Editor' function?

I want to create a custom 'Play from Here' context menu action, but there doesn't seem to be anything to trigger game mode

[tawdry surge]

Why?

[spice shell]

Because my default game logic doesn't support the existing one

It uses a specific player spawning system, so the default Play from Here doesn't work.

[tawdry surge]

At the risk of sounding repetitive, why?

[trim matrix]

Hi guys am i doing something wrong, ? I want the character to be able to use the animation only he is on the ground but when i jump and press on 1 it plays it

[versed sun]

You can also have more than one Return Node
This would return the first "Empty" Index, and if nothing found it returns -1

[spice shell]

I'd really rather just get an answer as to whether it's actually possible or not

[tawdry surge]

Its just a weird thing to do

[spice shell]

I understand

If it's possible I'd really appreciate knowing what nodes I might achieve it with

[willow gate]

Yeah I fixed it. I'm gonna revamp all this code. It was based on some examples I was looking at and the whole time I was thinking: "Why are there so many local variables when you can just use your function inputs directly...?"

[spice shell]

I don't think the specific architecture of my player spawning is relevant, sorry to be blunt

[trim matrix]

Found it !

[tawdry surge]

You wanna reinvent the wheel, be my guest

[spice shell]

👍 it's done for a reason, I've not just walked into Unreal for the first time and asked how to spawn the player 😛

So yeah, if anyone knows the node, much appreciated

This seems to be the inverse of what I want, but there's no pairing to Start Play, weirdly

[lunar sleet]

This is more #umg ‘s shtick but generally you want to use create widget and add to viewport nodes

[gentle urchin]

But also early return for cleaner looop breaks !

[keen flicker]

Hey guys I have been having an issue after following the unreal engine documentation to implementing character switching in my project I made a forum post on it. If anyone can assist it would be greatly appreciated https://forums.unrealengine.com/t/pawn-controllers-get-messed-up-after-switching/1327834

[lunar sleet]

1. You’re using level blueprint, don’t.
2. Your code in the player character is on begin play, cast to player controller and… nothing.
3. Someone gave you some code that helps set a ref to the currently controlled pawn. It’s an improvement on your code but it wouldn’t really do anything in its own

Are you following some tutorial or where did you get this stuff from

[keen flicker]

Character switching was done following the Unreal engine Documentation and the YouTube video linked in the forum post. The character movement and logic was done following this turtorial https://www.youtube.com/playlist?list=PL32YMM6O66N9ZCGD1mrqw__BcsxjZpkBt

[lunar sleet]

Ah ofc, forgot they left the level bp in that possess doc

[keen flicker]

Yeah I saw somewhere in the post similar to my issue that I linked in my post someone said the Issue lies with the Enhanced Input mapping feature in 5.1. I tried what they suggested that worked for them of reassigning it on possess but that does not seem to fix it sadly.

[lunar sleet]

It’s certainly a weird issue

For the speed, have you tried setting it dynamically on begin play?

[lunar sleet]

Also, do you have Unpossess anywhere?

I think you might be telling the controller to try possessing both at the same time

[keen flicker]

No, well only in the AI logic of checking to see if the pawn is possessed by a controller

[lunar sleet]

Ok, so try Unpossessing the current controlled pawn (get controlled pawn) before Possessing the new one

See if that helps

[lofty rapids]

what are you doing here ? it's a cast and then nothing pretty pointless

[terse trout]

does anybody know if it's possible to encrypt .ini files in a packaged game?

[thin panther]

You really don't want to do that

[lunar sleet]

No clue, maybe #packaging

[thin panther]

The point of ini files is to be unencrypted

If you're storing sensitive info in an ini you're doing it wrong

This is not even something AAA does

If you crash on boot due to a setting and cant even remove it from the ini, you're gonna have a lot of pissed off customers

[keen flicker]

I believe I am using the Character Movement Component for my input how do I go about doing that? Screen shot is for reference.

[terse trout]

makes sense, but what about cheating? in our game, the players are disabling fog and gaining advantage

[keen flicker]

Here's the possess macro in the level blue print where do place the unpossess node?

[thin panther]

The honest solution is to just deal with it. Most esport leagues play on low settings to remove disadvantageous environmental effects like fog and such

[lunar sleet]

Between previous character and possess

[keen flicker]

There was suppose to be UI related stuff there but I it disconnected it for the screenshot. At least from the tutorial, probably should not of sent that in hindsight

[lunar sleet]

Plug previous char into it^

[thin panther]

I'd go as far to say if removing fog is a massive advantage, then poor design is at play, and you have far too much open space, that you're artificially hiding

At the very most removing fog should be a minor advantage at most

There should be more visibility breakers that aren't fog

[terse trout]

it is a minor one, but and advantage nonetheless

[gentle urchin]

Lower fps / higher ping is another

[lunar sleet]

Level the playing field

[thin panther]

If it is just a very minor one, just leave it in.

It's literally how AAA deal with it. Like I said, most leagues play on low for those advantages.

Hell some games like pubg low settings remove grass entirely, which is a big advantage people just deal with

[gentle urchin]

If you know you know

If not, then its on you😅

[lunar sleet]

If not, your ass is grass

[thin panther]

Anyone who really wants to remove fog doesn't need an ini to do it either.
It's client side, so can be removed and be undetectable.

Encrypting an ini inconveniences everyone and doesn't solve the problem

[ionic palm]

The wind direction is a variable of the ocean shader the wind direction is controlled by the ocean manager. I assumed that the wind direction is 100% accurate to the waves as tweaking the value directly affects the wave direction

[keen flicker]

Similar issue, I also just tried to using the Legacy input/axis mapping in project setting as well and same issue occurs as the video. This issue also occurs with the Base UE 5.1 template 3rd Person template. The weird thing is that if I swap back to a character really fast it fixes all the issues. Any gusess why that is?

[tight pollen]

hi, how can I get the current size of the widget after scaling?

[versed sun]

Maybe?

[lunar sleet]

Not really tbh, but it’s clearly not enhanced input related

[keen flicker]

Yeah, thanks for the assistances thus far though. Is there away to like flush input when switching pawns? It my guess that might be the issue of taking the input context of pawn and putting it on another. Like resetting it where the input on the other character does not carry over. My goal it make a system similar to the Ultimate Alliance and Lego games for a Christian Superhero comic I got the author permission to use the IP and this really is the only hurdle I a have atm.

[lunar sleet]

The add/remove mapping context nodes have an options struct you can break that might help

[versed sun]

Flushing Input on the bottom of these

[terse trout]

yes, it is an inconvenience. but the question is, is it possible?

[ionic palm]

Anybody have any ideas why my camera won't rotate around my spring arm when in my ship?

I have checked everything mentioned online such as making sure enable rotation is on the spring arm and ensuring there are no rotation offsets for it to contend with.

Could it be the BP setup?

I just copy and pasted it from my player as I assumed it would function in a similar way

https://streamable.com/unepws

[versed sun]

The Ship in your world dosnt have the red spring arm line, try removing the ship and re-adding it from content browser

[thin panther]

anything is possible down in cpp land. but it is an astronomically bad idea.
there is a reason AAA don't even do this

its unfathomable

[versed sun]

I think sometimes BP in the world don't update when you change the BP

[thin panther]

people will just remove fog client side anyway. your ini change doesn't do a thing

the literal only way to prevent it would be to use something like pixel streaming, where you are solely responsible for running the game and merely transmit it to clients, like how stadia and such worked

you're actually screwing people over more by encrypting the ini files

because then you have to download external software to match someone who was playing on essentially low settings

it's like how low fps can be a disadvantage, so would you cap everyone to 5 fps to make it even?
some people have faster input devices so would you delay all inputs by 5 seconds?

of course not

Quick Question

Whats the difference between GameMode and GameModeBase?

[stark patio]

Does anyone know of a good way to setup an optimized status effect system?
Im trying to make a system where the different status effects can have their parameters changed on the fly and different status effects combining leads to different things. (the effects will be applied to lots of enemies and not the player)
All the tutorials i find either dont include basic functionality i need or would just be very performance intensive for my project.

[stark patio]

like the gamemode blueprint vs the existing one?

[astral orchid]

I'd say go for GAS

[astral orchid]

yee

whats the difference between those 2

[astral orchid]

Maybe a better question is to ask, what does GameMode have to offer?

[versed sun]

more multiplayer stuffs

[astral orchid]

I mean, that doesn't really tell much.

Do you mind expanding on that?

[versed sun]

is your game multiplayer? does it use spawn points ?

[astral orchid]

yee

multiplayer

[versed sun]

ok, use GameMode
GameModeBase is the bare bones , GameMode has a little extra stuff in it

[astral orchid]

What kind of stuff specifically?

OTHER than the Match State stuff

because that brings up a whole other set of questions

[stark patio]

i thought about that but it just seems a bit overkill and complicated

[astral orchid]

It's well worth it, trust me

[astral orchid]

So yeah, what else is there?

[versed sun]

Looks just like a few variables
No clue in the c++ side

[lunar sleet]

You can always look at the code

[north lynx]

Did anyone here knew the simplest way to create Hot Bar inventory? I don't want it to be displayed, but I need to create 3 slots where the player can choose by clicking 1,2,3 which slot they want to use right now
I can't find any tutorial about that, and can't handle it alone

[manic vessel]

After some playtesting, I have discovered that If my actual character is moving when I try to attach another actor to his hand either by setting the transform then a constraint OR just attach to component with snap to, My characters movement is causing the attached actor to not position where it should be . Like If Im moving forwards, the actor is attaching infront of the Hand position. and its the same for any direction Like its overshooting the target location\attach point by the direction I'm moving . Any one got any idea whats happening here? and how to solve it. Im wondering if this is a tick group issue

[faint pasture]

GameModeBase is simpler and has less opinions on the structure of your game. It's more of a blank slate vs GameMode which has the concept of match state and other things etc.

[native ferry]

get cached geometry > get absolute or local size

[ionic palm]

It does have the line I just didn't have my ship selected in the video I tried replacing the BP and same issue though good suggestion

[versed sun]

bummer

[ionic palm]

Everything online is just saying it should be a matter of putting update rotation on your spring arm without even touching the event graph but it doesn't seem to be the case for me it is an issue on my end I just have no idea where I have went wrong in this like 2 step process haha

[lunar sleet]

I’ve seen someone with this issue

They had checked use control rotation and that stopped it from acting as a pivot

Fricken autocorrect I swear lol

[versed sun]

When the game starts , are you viewing from the Character , then changing to Ship Cam ?

[loud tree]

I think I'm horribly misunderstanding something here. Have a multi sphere trace going out to set an aoe effect.
When I use a string to check the length of the array on the output I see all hits registered.
When I check what's being hit from either the break hit or the pawn hit, it only displays one (guessing the first) hit/display name then only applies the effect to that one.

[lunar sleet]

Where is this print

[versed sun]

The Return Node is going to stop the Loop

[loud tree]

Rn it's outside the function attached to the 3ppball
But I had tried it attached to the cast, break hit, and splitting the loop instead of break hit.

[loud tree]

Gonna try removing it then,

[lunar sleet]

If you don’t return anything what will print ?

[loud tree]

if I don't hit anything nothing runs as it runs off the false hit

[lofty rapids]

it looks like you apply the effect on the return value ? you probably want to do the line trace outside the function and run the function forEach, or make the return value an array you can use

[lunar sleet]

I said return not hit

[loud tree]

I guess I'm a little confused by the terminology here. I'm pretty new sorry.

[ionic palm]

I fixed it!

My issue was I had inherit yaw and pitch unticked as it was not ideal when the camera was static bobbing with the ship but I thought I would be able to rotate around the ship without inheriting the motion but apparently not without any BP or code at least.

https://streamable.com/9fzhwt

I have another small issue that you can see here.

Basically when my character is socketed onto the ship when steering they have collisions removed in this process as it caused weird physics. My issue now is that the anim montage that plays the wheel animation plays once and then the character thinks they are falling as there is no collision,

I just had a though while typing maybe if I set his movement type to flying he won't think he is falling but would love any suggestions if that doesn't work

[lofty rapids]

you probably want to return an array and use that to apply to all instead of just returning one.

[lunar sleet]

Put whatever needs to happen in the function itself

[loud tree]

I think I get it, working through it rn. I'm a little slow atm cause I have my kid with me watching videos while I work

[lofty rapids]

just add to the output array local variable in the loop body, and on completed return the output array as an output

then foreach through them and apply the effect instead of just applying to the single

[lunar sleet]

Or just disable collision between each other, not everything

[ionic palm]

They can't collide with eachother I noticed when I left collision on and possessed the pawn (MyShip) it seemed like it was using my characters colliders/mass/physics instead of the boats collision/mass/physics settings. This led to some interesting floaty donuts but not the intended gameplay haha

[lofty rapids]

what did you use for the water ?

[ionic palm]

It's the cartoon water shader asset its really easy to reference all the gerstener wave stuff out of the box in BP due to its setup such as wind direction mainly for my game

[lofty cloak]

how can I "bias" this random float I have so that fewer actors have a higher Emissive value?

[trim matrix]

Hey can somebody help me. Im on rx 7600 and keep getting crashes saying something like d3d. In particular when editing blueprint

[ionic palm]

Do you have a busy scene?

I had crashes a little lately but I had a 6x6km ocean in my level haha

[trim matrix]

Nope, the screen just turns black randomly and it crashes

[loud tree]

Thank you for getting me set in the right direction. Removing the return node does allow the trace to see everything. Gonna experiment in a bit with setting it to an array and seeing if I can get that to work out. Otherwise I'll end up going with the other suggestion

[lofty rapids]

whatever works

[lunar sleet]

It’s important you understand why this is happening and why outputting an array was suggested

[sick fable]

I know your an expert do you have the answer to my question in general

[lunar sleet]

I’m no expert lol but I’ll check

[tight pollen]

in Data Asset can i have Array with widgets?

(references)

[lunar sleet]

Afaik, DAs are created before runtime so you can’t really have refs to instances in them

Because they don’t exist yet

[loud tree]

I think so...?

Basically I was making the array and trying to pass those values through the return that was set to read/pass a single value instead of being able to see all of the actual hits in the array.

[lunar sleet]

Yeah, and when you use return in a function it exits it immediately. So if you want to check within all values found you need to output the entire array, then do the for each loop outside of the function

Corrected for accuracy 😅

[loud tree]

Makes sense. Thank you again! Not just for the help but making sure I was actually understanding.

[lunar sleet]

Forgot to add, if you want to say cast to something and filter the array that way, then run your return node off the completed pin, so it only exists once it’s iterated over the entire array. You’d have to feed that specific result into the output value. Again, this is for singular output. Else you’d have to make a new array from the results and feed that out, etc. 🙂

[undone sequoia]

how do you use multiple post process materials or how would you go about it? i have multiple instances of the outline and want different ones depending on conditions

[frigid cradle]

I know it's important to the engine but what exactly is the point of blueprint? I've felt like I've been bashing my head in a wall trying to learn it. I've known how to code for a few years now and despite not being an expert or anything (just average) it's still throwing me for a loop. Is there any reason at all to use BP instead of C++? I'm a solo dev so it's not like I've got designers I've got to send these things to.

I've even done other visual scripting things before in college classes and I tried Unity's (terrible) version of it

[thin panther]

The point of blueprint as to why it was made is as a tool for game designers to make gameplay elements

The point of blueprint for you personally is to subclass c++ classes. You can't match it's iteration speed, and asset referencing. Quick gameplay code and asset referencing are your strengths in BP. Core logic, manager classes, base classes and unperformant BP code should be done in c++

[desert quarry]

What's the name of the sky sphere that makes stars? Is that still in unreal 5?

[thin panther]

You can expect your primary workflow to be making a core base class in c++ and subclassing it in BP to set up asset references and overriding various functions/implementing events

[frigid cradle]

So something like implementing a health system in C++ and then an enemy in BP extending it?

[thin panther]

Something like that yeah

[frigid cradle]

Thanks

[desert quarry]

I generally make the logic in C++ and then use BP for instances of things.

Also bp is great for testing things.

you would always use the forward vector as reference for your jump velocity

so when hitting jump you apply a velocity, which could be the (scaled) forward vector + some zOffset

[carmine apex]

How would I put that into blueprints

The branch isn’t connected, so it can never be called for one.

After destroy actor I would, and also shouldn’t the logic on the branch be = 0?

Hello!

I am trying to create a mount system. Im recreating something like World of Warcarft, when you hit a button, Spawns your mount, Attach Actor to Actor.
So far I have gotten this far and got this part to work in my multiplayer game.

Since my game is a multiplayer shooter game, I was wondering how to go about the next step.
This is new for me, so If I posses my mount, my understanding is that you swtich to your mount blueprint and you loose all the logic you put in your main character BP,
So I dont get any damage anymore as the logic was on my main character,
So I have to recreate my movement inputs and logics on my mount too?

I am wondering if this is the right approach,
I want my character to be able to shoot while riding and still keep all the blueprint logic I added,
So I think my question here ... Is there a way to control a mount without possesing it ?

Been stuck on this for a few days and strangely it seems to be very difficult to find a clear tutorial for my setup.
Does anyone know how to go about this?

[trim matrix]

does anyone know of some good sources for stopping this material from stretching?

[iron prawn]

Nice! Just one small thing though, you are setting the remaining variable after decrementing it, but this isn’t necessary as decrement int automatically sets the variable for you.

Could anyone help me with a character-swapping issue? So I want the player to be able to swap into objects, I have the logic for that down and I'm able to swap. But I want the player's collision to be disabled and use the object they turn intos collision. I tried setting the capsule collider to the same size as the can in the image. But that did not work as the offset is wrong, and if the player turns into a box, this also won't work. 😄

[carmine apex]

@lunar sleet yes it would be able to side step, but i'd like if it would only jump in one direction and walk slowly so jumping is the main way of moving

Right now I'm stuck on the character only jumping in one direction (characters facing)

Any help on this?

[lunar sleet]

Prly the simplest way would be to set a Boolean to True while strafing and only let the jump run if that is false

[opal pulsar]

does anybody know how to properly rotate an object with the mouse with a physicshandle component?
basically the Z axis is fine since its globally up
but other axes just seem to be relative to the object
what im trying to do is use the Y axis of the mouse to rotate the object on the player camera's Y axis

[trim matrix]

is there a way to make my tile adjust as i scale it automatically?

say no matter what way or size i scale it? that it stays the same tiled size

[versed sun]

yes

https://www.youtube.com/watch?v=JW8LfB5Gkm0&ab_channel=PeytonVarney

[versed sun]

As long as the mesh isnt moving , this works awsome

[trim matrix]

wonderful i will check this out thank you!

[manic adder]

in a bp that is constructing InstancedStaticMeshes, enabling physics is greyed out.
the mesh has a box collision applied. what other causes need i look at ?

[versed sun]

I don't think ISM can have physics

Alternative would be replace that instance with a regular static mesh with physics enabled

[manic adder]

in this case, will i be able to work material variations, such as with PerInstanceRandom ?

[versed sun]

yes, with Custom something something.... once sec

https://www.youtube.com/watch?v=knO3R5g0s8s&ab_channel=AlexQuevillon[En](UnrealEngineTutorials)

[manic adder]

but this applies to instances

[versed sun]

Did you want ISM with different materials per ?

maybe i read wrong

[jolly cipher]

The way to go about this is to attach my main character to my spawned mount actor and then disabled my main character's input, create a blueprint component and blueprint interface to pass on the inputs of the main character to my mount and so far I got it working

[manic adder]

ah yes, will have a look at keeping the instances then. thanks

but i need to apply physics at the same time

[carmine apex]

How would I make my character jump forward instead of straight up

[spark steppe]

i told you half a day ago

use the forward vector of your character

[fiery swallow]

he's probably referring to the node he will need, which is "launch character"

@carmine apex

[hollow cove]

im brain farting on how to do this, if i have four booleans and an enum, if bool 1 is true then enum should be 0, if bool 2 is true then enum should be 1 etc. what's a way to do this without tons of branches

[fiery swallow]

it would help to be a little more specific, what are the booleans for? and what's the enum for

[hollow cove]

i have a bunch of conditions to figure out why someone cant place a building e.g. blocked or too steep land

want to put it in an enum so i can just switch or select for a message or whatever

[lunar sleet]

Seems hacky. You should prly be possessing the mount and replacing or superseding the mapping context but I can see how possessing both could cause some problems

[hollow cove]

prioritizing by the order of booleans that are true

if boolean 1 is true then set the enum to that instead of 2 which is also true

i guess a for loop with a break could do it

[fiery swallow]

you shouldn't need any booleans to prioritize the issues

an enum would be fine, you would prioritize the error message by prioritize what's the most important from what's the least important

[hollow cove]

mhm it was about how to convert the bools to an enum in a way without tons of nodes

[fiery swallow]

If that makes sense, If you feel like wood for example is more important then collision, you'd check if they had enough wood first, and if they didn't then that's the error

oh

[hollow cove]

could just throw them in an array and loop to set an enum and break tho

[fiery swallow]

you could just replace the select bool with a select enum

but this code seems very unstable and/or hard to follow :/

and you'd have more then one select

[lunar sleet]

Would switch on enum work here?

[vapid patio]

ah ok thanks. I swear the more I learn about unreal and all its amazingness, I also learn how limiting blueprints really are. I tried creating a c++ class but everything was broken. It opened wioth a ton of red lines and I had no idea how to move forward. Hardplace and a rock

[fiery swallow]

he's trying to figure out what the enum would be

[hollow cove]

i would be setting the enum from the bools here not using an enum

[lunar sleet]

There’s some prep involved

[fiery swallow]

yeah you can select an enum from the bools

if you'd show some more code I can give you an example

[gentle urchin]

Does the avtual blocking bool matter ?

Seems like all of them are just to ensure invalid location

And if so... anding them together is all that makes sense

[ember hazel]

I have multiple items that need to play a sound and effect at the same time but in different places how can i make it so that they dont just play at one of them.

[lunar sleet]

You’ll want to disable Hot Reload and re-instancing, and add a couple of extensions to your IDE of choice, #cpp is very helpful

[hollow cove]

i just did this

[fiery swallow]

I mean that's... better, but you don't need the break there, you can just dirrectly connect the braanch to the return value

the loop will stop on it's own

[hollow cove]

oh true, it's a return

[versed sun]

I would do this

[lunar sleet]

I believe the goal was to avoid that many branches

[hollow cove]

i would connect the false of the last branch to the start just incase a cosmic ray causes bit flip

[lunar sleet]

So infinite loop?

[hollow cove]

absolutely, only way to be safe

[lunar sleet]

Confirmed inf. loops verified as valid cosmic radiation protection

[fiery swallow]

https://i.gyazo.com/46fd878acc92f21c3206827f107a3a15.png

I whipped this up quickly, this is how I would do it

[hollow cove]

hmm, it is cleaner but it has more nodes, and a lot of the bool checks i have are pure

[fiery swallow]

I'm not sure why the second part matters

[gentle urchin]

But... do you use the outputs ?

Like. All of them, for different things?

[hollow cove]

the enum is just to notify the person why they can't build in that location

[gentle urchin]

Right

[fiery swallow]

Well, the method you had in your previous image works too, although I think this is a more proper way to do it. You can come back to this in a year and quickly understand what's going on and make the changes you need efficiently

but either way I think you've got it

[gentle urchin]

I prefer unreadable code

Combine all bools to an int

And decipher the meaning in a year without documentation

[fiery swallow]

I've never heard that one before LMAO what

[gentle urchin]

Nah id let it be single bool output and probably a text to describe the issue

But far cleaner with branches

Along with very clear prio

[fiery swallow]

can't forget the string cheese code where one variable on the blueprint board is connected to 50 different things left and right

[gentle urchin]

Ah ye 😅

[fiery swallow]

https://i.gyazo.com/e89655560a0a61e6ccb950f093c2870f.png

best part is the comments are so helpful

I remember a contract job I did a while back I seen a comment in the blueprint graph for a huge function like this. Inside of the function the comment wrapped the whole thing and it said "does stuff"

[gentle urchin]

And good naming of var

[fiery swallow]

lmao

[lunar sleet]

Bool 1 True = 1, Bool 1 False = 2, etc. 😂

[sand slate]

Hey guys, I have a simple question. Is there a way to connect an enum value with an other value or ref (like in this case texture). or is it always done like this?

I try to change the tumbnail picure to the selected map. with a switch. I use this technique alot but maybe there is a more easy way.

[hollow cove]

can make a map but idk if theres a better way

[iron prawn]

Select node?

[fiery swallow]

I see, making it more optimized by not using the built in bool to int conversion 😂 I'm writing this down

[gentle urchin]

Select indeed

[hollow cove]

oh true, select if you're only doing it once

[fiery swallow]

a map wasn't wrong though, but more work for no gain 😅

[hollow cove]

maps are annoying af with the default value not being allowed while adding more to it

[spark steppe]

FInterpTo Constant... interp speed 1, will blend from 0 - 1 in 1 second, right?

[sand slate]

Perfect, select node looks good. Thanks guys!

[hollow cove]

not sure about constant, but the other interp nodes dont work like that, they have some formula you can look up

[lunar sleet]

You’ll have to plug in delta seconds prly and from what I was playing with on FInterp, that’ll make it spit out weird values

Tbh idk how to use FInterps properly, thought I did but nope

[spark steppe]

yea just checked with print string, sometimes my brain doesn't come up with the easy solution...

for the constant interp it's pretty much interp speed * delta time

so whatever interp speed is will happen within a second

0 - 10 with interp speed 1 will take 10 seconds

[carmine apex]

I made this blueprint attempting to make the character jump forward in the direction it's facing but it isn't launching me in the forward direction, instead it's launching me to the left...

[lunar sleet]

Finterp works diff I guess. I was trying 0-10 and it never reached 10

[spark steppe]

this is crouch code!?

[carmine apex]

Wrong one my bad

[spark steppe]

yes the constant and the normal interp nodes behave different

[carmine apex]

I made this blueprint attempting to make the character jump forward in the direction it's facing but it isn't launching me in the forward direction, instead it's launching me to the left...

[spark steppe]

i think for normal interp it's a fraction of the delta between initial and current value

[lunar sleet]

Aah, that makes sense

It kept oscillating back and forth

[lunar sleet]

Get actor’s fwd vector not mesh

Self should do it here

[spark steppe]

your mesh is probably rotated by 90deg

there's a get actor forward vector node

his current node is for scene components, so self on it might not work

[lunar sleet]

Yeah true there is, I forgot there’s more than 1

[faint pasture]

You should make some structs with those things in them

[ashen gazelle]

Getting this error, trying to create a respawn system when you fall out of bounds

[lunar sleet]

What is calling respawn player?

[ashen gazelle]

my level, it has a trigger box that i want to respawn the player when they hit it

@lunar sleet

not sure still, cant prod this one out

[hollow cove]

is there a select or switch node for materials using index

doing a custom stencil and if nodes are annoying

[sleek coyote]

Hello,

I'm still relatively new to coding in Blueprint, but I've been trying to search and see if there's a way to create a simple box (for collision) that encompasses a linear spline point loop. I can do collision boxes along the loop very easy, but that doesn't solve the problem of having collision along the top of the box (say, the player drops into it, or flies near it).

[lunar sleet]

Show code and don’t do stuff in level blueprint

[plain cobalt]

This returns 0 when I print it, while i tested my array elements. They do have proper values. Am I just being totally oblivious to as why this doesnt work or am I missing something

When I print the sum I should clarify *

[lofty rapids]

you print it on completed ?

[plain cobalt]

yeah thats the node im not showing

[lofty rapids]

how did you "test" you array element ? try a print string out of the loop body see if there are elements in array and it's running

[plain cobalt]

Thats what I did, I printed string out of loop body with the value and index number of each array element

Okay soo nevermind somethings goin horribly wrong

..Im an absolute idiot.. i think

Yep lmao it had nothing to do with that piece of code, I used a similarly named obsolete array that I forgot to delete 🥲

[jolly cipher]

Just curios, has anyone ever had issues turning / moving camera after attaching my main actor to a horse mount?
Seems like my input are generating values n my horse mount for my controller Yaw and Pitch.
Been going trough all my settings but not seeing anythinig obvious.

Seems like once I attach my Actor to my Horse Actor I just loose the ability to move my mouse around.

[hollow cove]

hmm why isnt fmod working, seem to be getting 0, 2, 2, 0, 2, 2 as i increment the value

tried doing, floor, ceiling and round and same results

[lunar sleet]

Hard to tell, does a material bp even let you print ?

[lofty rapids]

probably #materials @hollow cove

[blazing wasp]

if i have a camera shake actor that's a child of a camera, and it auto plays, is there any reason why i should expect the camera not to shake when i hit begin play?

(this does not shake the camera at all)

[native ferry]

hey is there a way to reduce the on paint function frequency in a widget? I have this on paint function that runs every tick and i'm afraid it will reduce performance due to the amount of math there is

or i don't have to worry about that?

[native ferry]

using cpu profiling i see that it takes 1ms of cpu time, is this a lot for just this?

[sterile quest]

How do I change the collision preset from within the event graph? Currently I have it set for a mesh to "No Collision" but I want to be able to change the collision preset via BP.

I tried searching for relevant BP nodes but came up empty-handed.

Basically want I am trying to do is change a morphtargets value and then enable a collision mesh (that's invisible) after the morphtarget value has been changed.

I'd also have to disable the other collision mesh after the morph target is changed.

Some help with this would be appreciated.

[red berry]

Is it possible to do nested actor components or not? I know you can add an ActorComponent to an Actor, but what about ActorComponent to another ActorComponent?
The AddComponentByClass's target only allows Actors, but I don't see the option to allow an ActorComponent

[jolly cipher]

I tought maybe this could have been a collision issue but setting them both to no collision in the live editor still prevents me fro moving the camera ...

[lunar sleet]

Maybe try #profiling or #umg

[lunar sleet]

Maybe show the code that happens when you take control of the mount

[lunar sleet]

Depends what you mean by nesting

You can add multiple components and attach component to component if you’re talking attach

[red berry]

I want an ActorComponent to have some additional data/objects with it, so if I move the AC to another actor, it will bring them with it.
I do this so that the single ActorComponent is modular and has its code split up. I don't want 2 or more functionality in the same blueprint. Seems like I have to do this in C++ by allowing UObject which can be replicated.

[lunar sleet]

Yeah I don’t think you can add components to components normally

[red berry]

So the only option is to port my ActorCopmonent over to C++ and the sub ActorComponent over to c++ too but as a UObject? Then I add the sub object to the main UActorComponent via AddReplicatedSubObject()?

[lunar sleet]

Maybe, that’s a bit beyond me, I’d ask the crew in #cpp if that’ll work

[red berry]

Oh well its a problem I'll deal with in the future

[dawn gazelle]

If your component needs other components to work, then that's a sign it's not designed correctly. The component should have everything it needs to act mostly indepedently. It can still make sense if the actor that will be owning the component has to make calls into the component, but otherwise you're losing the benefit of even using a component if that component is reliant upon the actor having other components.

If you have similar code in multiple actor components but have some code that you only want in a certain component, then that's a sign you probably want to subclass your component.

[desert juniper]

And then lyra steps in with 20 (hyperbole) nested components

[red berry]

Are they blueprint or C++ compponents?

Is there a point in checking pass by reference? I know about programming, so passing by reference typically means a bit more better performance. Does this actually do anything? Im thinking of checking it true, if I'm simply getting variables from the argument.
But I think it can backfire because if you pass by reference an argument and accidentally edit it, you would be editing the original unintentionally. But if you don't pass by reference, you're making a copy of the object which is slower and takes up more memory

[hardy fable]

that is correct, but for a UObject pointer, what it would be referencing is the Pointer, not the object. so you arent saving memory, since pointer and references are the same size

for structs, yeah

you cant copy UObjects like that. the checkbox changes the UObject* into a UObject*&. Except that this is the BPVM so it probably does nothing at all, to be honest

except I guess, you could reassign a new object to the variable that was passed into the function

[red berry]

I'll just leave it unchecked just to be safe, because if it works and it isn't broken, then there's no need to fix it. And premature optimization is bad

[hardy fable]

yeah, there is barely any point to using that for objects. for structs and other PoD, use it if you need to modify the original.

also, keep in mind you are working with "virtual memory" here. BPVM will happily make copies of stuff you tell it to pass by reference, so the "savings" you'd get by doing that for large structs is . . . questionable anyway

[desert juniper]

Lyra is basically all CPP
The entire core is written in CPP and only the variable gameplay bits are in blueprints

[fringe junco]

how would i use the new enhanced input system? i have my input actions, the input action context, but my little tid bit of blueprint returns 0.0 and doesn't add anything to pawn input as a result

[crude pecan]

Thanks, I guess that makes sense. It's still useful outside click drag if it's only a single click action

[minor wolf]

What sort of code goes in construction script vs begin play? I'm looking to make an inventory component and want to add in an inventory size. For most defaults this will be a static number entered in the defaults panel per blueprint but I'd like to have an item that has an inventory size of max int32. Since I can't access such variables in the details panel I was thinking it probably goes on construction script or begin play

[subtle wyvern]

How can I trigger an animation blueprint using blueprints? I have a lipsync animation, so when the player collides with the metahuman the lipsync animation plays - but when it's done I want it to go back to it's original animation

[dawn gazelle]

Construction Script can happen before runtime, for example, when you place an actor into the scene or move it around in the level editor then its construction script will run. It's also run when the actor is being spawned too, and should be happening before begin play.

For an inventory, it technically wouldn't matter whether it is in begin play or construction script, but begin play would make more sense on account that you don't necessarily want to have the inventory resizing itself every time you may move it around in the scene.

[minor wolf]

Ideally I'd like it to be part of the cdo.. I think. I could just manually enter in the number manually I guess

[frosty heron]

have montage slot in your anim blueprint and just play the montage

[drowsy anvil]

Hello, how do I make this projectile shoot in rapid fire, while I hold the button down?

[tame pecan]

Easy solution: Make an event that ticks every X seconds

when you hold down the button

[gentle urchin]

Timer event i guess

[drowsy anvil]

I did this for rapid fire, but they keep still firing after I die

[tame pecan]

That's a very complicated solution

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Utilities/Time/SetTimerbyEvent/

[drowsy anvil]

oh, is it not optimized?

[tame pecan]

Don't really bother too much with optimization, just that it's a mess

set timer with event makes this all into 2 nodes

[astral orchid]

How does the Match State machine work in GameMode (not GameModeBase)? How do you change the state, or call states to activate functions?

Ping me if you have an answer

[radiant imp]

How can I get the player state from the player controller?

I don't know how to get the Player State Index of the current player

[serene crater]

How do I check if a property is a nullptr in BP? IsValid() doesn't seem to do it

[tame pecan]

what do you mean? sounds like you got a dangling pointer if so

[unreal vector]

Hello people, I'm coming in!
I would like to know if there's a way to save sets of nodes, like presets, so I can quickly reuse combinations of nodes without having to recreate them constantly?
I'm mainly asking for metasounds.

[sweet silo]

hi there i don't understand when packaging the game modes i set as default by levels are reseted to the basic game mode.. any idea? thanks

[serene crater]

I want this check to fail if the property is none

[tame pecan]

That would work as intended

the only case it doesn't work, is a dangling pointer

[serene crater]

What do you mean by dangling pointer?

[tame pecan]

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

[serene crater]

Surely if it's dangling then it's not valid

[tame pecan]

it's a false positive

That's the only reason a IsValid would point to a "valid" object when it's not valid

[serene crater]

Any ideas how to go about fixing it?

[tame pecan]

What is parent frame?

is the object pointing to an address?

[dark drum]

I'm pretty sure the blueprint isvalid node takes this into account.

[tame pecan]

It's calling IsValid()

[dark drum]

You have functions and macros. If they need to be used in different BP's you can look at making function/macro libraries. (Please note, these can't be accessed in custom uobjects)

[unreal vector]

Thx for your answer ! Is there a way to do that in metasounds ? 🤔

[dark drum]

Chances are they've probably just created a var of a specific type but don't actually set it. I've never once had any issues with dangling pointers using BP.

[dark drum]

I don't know, i've not used metasounds. Ask in the #audio channel, they might be able to give you an answer.

[unreal vector]

okay thanks 🙂

[dark drum]

Do something like this but when the player dies, clear and invalidate the timer.

[fringe junco]

hmm any thoughts on how i can do a proper camera rotate? this seems to spin the camera at mega speed

[dark drum]

You don't have delta time connected which would affect it. Get Delta world seconds. What are you trying to do? Just rotate the camera based on player input?

[fringe junco]

i see hmm

yeah

[dark drum]

There's an example in the first/third person templates for rotating the camera. Are these not what you're wanting?

[fringe junco]

ill take a look, thank you

oh wowza it was a simple

[feral ice]

hello guys! Is it possible to spawn a landscape in level blueprint in ue5? Like during runtime

[dark drum]

I don't believe it's possible via blueprints.

[fringe junco]

maybe look at the cropout sample projecy

i think they do something in BP similar to what you are asking

[feral ice]

ok but its not even possible to spawn in an actors blueprint?

or is there a landscape actor i can spawn in in class

[dark drum]

I don't think you can add a landscape to a blueprint. (I might be wrong) The issue with landscapes is you can't edit them at runtime using BP so even if you were able to spawn on in, it would just be flat.

[feral ice]

cause my purpose is to create a number of randomly generated landscapes

[feral ice]

do you think there could be a work around in blueprints. Or should i look in to the cpp

[dark drum]

What are you trying to do?

[feral ice]

this

[dark drum]

are you wanting the player to be able to walk around them or just in the distance? You could use a custom mesh component and build a tesselated plane. This might not be the most effiecent method though.

[feral ice]

yeah i want the player to be able to walk on the landscape. Cause i want to add landscape material on the landscapes

[drowsy rapids]

Hello, can anyone teach me how to access asset details/properties/info/data (not sure what it's called) from BP? For example, how would I get the imported dimensions of this power of two padded texture in BP? GetSizeX/Y will only give me the final padded texture dimensions (32768).

[tight pollen]

how to use it?

[thin barn]

where is the decreement operator in widget bp? i cant find it

[tight pollen]

I have one main widget with several variables that I want to be present in all widgets. Variables are saved and loaded, there are several widgets in which I want to have other variables and also save them, and I don't know whether to put these variables in the main widget (Parent Class) and when loading variables, those that will be applied only to specific widgets, will they simply be empty in those widgets that do not use them, or is there any other way? anyone advise?

[edgy ingot]

Decrement operator is -- , just type decrement on your int variable.

Whats that got to do with widget bp or any bp tho?

[thin barn]

actually it was a glitch, i was trying to search for -- node and it was only showing subtract node after sending a msg here i restarted my unreal and it showed when i searchrd

[red berry]

Is there a way to transfer an ActorComponent from one actor (its owner/parent) to another?

[lunar sleet]

Why transfer ?

[red berry]

Thats for scene component, the 3d stuff. I need Actor component, for abstract stuff

[lunar sleet]

Why are you trying to xfer a component around

[red berry]

I have a backpack that has an ActorComponent inventory. If the player equips it, the ActorComponent should still exist, but be transferred to the player. The "AC_Inventory" handles the backpack's storage, so it should always exist, whether its in the world, or on the player's back. The 3d mesh however doesn't always need to exist

[lunar sleet]

The simplest way would be to hide the mesh.

[red berry]

Bruh unreal engine seems so inefficient. Logically I would keep the data, but delete the 3d mesh when necessary, and recreate it, when necessary. You can't even transfer an ActorComponent from one Actor to another, it seems. You can't even subclass actor components to split them up either.

[lunar sleet]

Sounds like a design issue

There’s absolutely no reason for you to xfer actor components around

If you want to store an inventory system in an actor component do so

It should always be on the character itself. Idk what you’re trying to do by passing it around like it’s a real backpack in a school yard. If you need to pass the items to another char you would do that, not try to remove a component from one actor and add the same instance of it to another actor

Having said that, you can do anything with cpp if you put your mind to it, so if you want to go down that rabbit hole give ‘er

[red berry]

@lunar sleet I have an inventory grid based system. The player can't equip items unless they have a backpack on. If they take off that backpack, the items stay with the backpack and they can re-equip it again and see the items again.

[loud cipher]

Hey all i have a simple linetrace that casts and checks for an actor hit, and if it hits an actor it unhides a widget on that hit actor that shows F to interact. But the problem is, if the player then looks away hit actor becomes invalid and it is impossible to then hide the widget that shows interact

[lunar sleet]

Doesn’t mean you actually need to remove it. Only obfuscate it from the player’s POV

[lunar sleet]

Where are you running the trace from, tick?

[loud cipher]

yeah basically, just a timer by event name with a value of like 0.2 for time

[red berry]

I have the backpack 3d mesh Actor, with a AC_Inventory component that handles its storage. Am I supposed to just merge them or something? Do I just simply attach the Actor to another Actor (player)? Is that efficient to do so?
It may be a player having 1-3 backpacks, but NPCs will have inventory too. So if we have 100 NPCs, thats 400 actors in the scene. Can Unreal even handle that many actors?

[lunar sleet]

This will require testing in case it’s too jittery but on cast failed you could remove from parent

[loud cipher]

how though

Remove what since i cant access anything from the bp

[lunar sleet]

Save a ref to it

[loud cipher]

Okay thanks

[red berry]

Not sure if I can help, but I managed to make my hover to interact functionality work. I use the player's EventTick to handle the raycast. If it hits, I call the function in the UI to display the interact actions. If it doesn't it, I call the function in the UI to hide. Not sure if thats your problem

[loud cipher]

Thanks, yeah its similar but im having it as a physical widget inside the interactable bp and not a ui element widget

[lunar sleet]

Show current code if you can’t figure it out

[lunar sleet]

Yeah, I would just do attach actor to actor if you’re doing it that way, idk about merging though, at most I would just iterate over each one and list the items in the same window if that’s what you’re looking for. Unreal can handle a lot but it all depends, can’t really optimize before you’ve tested and profiled.

[grave relic]

Does anyone know if it's possible to change the player into a static mesh, and then make the player controller use the mesh collider instead of the capsule collision? I'm trying to do something in the style of a prop hunt, but I want the collisions to be accurate to the objects. So if the player is a box it has that collision, and if it is a can I want it to have that smaller cylindrical collision. I have to logic down of swapping the player's mesh, but I don't know how to change the collisions.

[native ferry]

i think how it's done is that they hide the skeletal mesh and attach the static mesh to the root bone

because if you've played fortnite's prophunt for example you can still see the animations playing when you've transformed into a prop

[loud cipher]

Saving as a variable worked thanks

[native ferry]

i don't think you can change the default capsule collision but you can still scale it to the mesh size using the get component bounds node @grave relic

[grave relic]

Hmm okey, so If the player is a box, then im unable to use the boxes collsion? Or should I just make the capsule component really small and the box collsion will be over it, taking priority? And how do I attach the static mesh to the root? 🙂

Currently I have it set up like this:

[native ferry]

i was talking about the root bone of the skeletal mesh using the attach component to component node but this works too

as for the box collision taking priority i don't know if it will work, you can try and if it doesn't just scale the capsule collision instead

also you can scale down the capsule only to a certain size, if the static mesh is too small you won't be able to do what you suggested

but it should be enough

the minimum scale is 1 so i don't think that's an issue actually

[loud tree]

One option would be to add all of the meshes tied to their collision sphere/box/etc to your player character.
Set them all mesh and collision to "auto activate off" and "hidden in game to yes".

Then when you switch to that prop
Write code to set the current or all other meshes/collisions to inactive and hidden in game while the collision and mesh you want is set to active/unhidden.

Sorry bad phrasing collision is always hidden
Set meshes between hidden/unhidden and active/inactive
And collisions
Only between active/inactive
Always hidden

[lone delta]

hi guys! I'm trying to attach my player to a rope (it's made from bones simulating physics to get attached on any point of the rope), but no idea how to do it correctly.. If I attach the actor it makes it look very wrong when swinging (screenshot) from being attached by the root I guess, and I have no idea how to work on the rotation issue..

[keen flicker]

Just want to bump my issue from yesterday in incase anyone can help me out with it today

[grave relic]

This might work, but I plan to have a lot of different meshes and this might be to heavy of a system, but I will try it and if it works, then this might have to be the way to do it.

[loud tree]

As long as auto activate is off, I think it should be fine.

If this doesn't work for any reason you could try making a BP for each mesh with their own collision, then spawn them in with spawn actor from class as needed.
Once it's spawned you can take possession of it.

Hey yall

<Fade>Fire Resistance:</> <FadeYellow>{fireress}%</>

im displaying my fire resistance like this

and im getting a float and * by 100 to get %

but when i got a negative value i do the same

[grave relic]

This might work, I will try it 🙂 Do you know if its possible to do this with a line trace, so if I linetrace and hit a target, the I can posses it?

[steady night]

the text is begin displayed like this then

the Font im using do have -

[supple osprey]

@versed sun Thank you for your help. 🙂 I think I phrased it wrongly yesterday. I want the inherited function to have additional input pins...do you know if this is possible?

[versed sun]

I would override the function in the Child and copy the Parent: Node
Then Duplicate the function and paste >expand node in new function
Add your new pins and code it as needed

[neat sinew]

Is it possible to have a scene component unaffected by parent rotation? I want only the location to be relative to parent

[loud tree]

Yeah that is a way as well.
You can find guides on YouTube for how to do that.
If you can't lmk and I'll dig one out

[brisk badger]

Click on rotation in the transform section of your component and change it to World rotation

[neat sinew]

I tried that but it doesn't do what you'd expect. It will still be positioned relative to character rotation, but the component rotation will match the world location

I think ill just do it manually... Ill spawn an actor then add the character velocity to it

[brisk badger]

ohh I see what you mean, I had that issue when it came to putting a hat on a rolling ball a while ago, my solution was to put the hat in a BP and raise the mesh up while keeping the origin of the BP to (0, 0, 0)

[supple osprey]

@versed sun Thank you, I think I will go with that 🙂

[sterile quest]

Still hoping for some help with this: #blueprint message

[brisk badger]

as long as you make the root of the component at 0, 0, 0 then it wont have any issues, you could make a scene component there, turn it to absolute rotation, then put another scene component as a child to that one and have it where you want it

[lunar sleet]

Set collision response to channel/all channels

It uses a component as target

[sterile quest]

Thank you.

[neat sinew]

Oh I think i see what you mean. That would work if I could change the root component... In the case of the character you cant really do that since its hard coded in cpp. So everything moves with the capsule. Or maybe I can change the root once again in the child class constructor?

[lunar sleet]

Can’t change parent root from a child afaik

But like, why would it be hardcoded in cpp? Seems counterintuitive

Unless you’re saying the default char class forces you to use that

[neat sinew]

yeah default ACharacter sets root to capsule

[lunar sleet]

Oh, I getcha

[neat sinew]

I will try it tho

prob gonna mess things up..

[brisk badger]

you don't have to make it the root, set the scene component's position to 0, 0, 0 and set to absolute rotation, then make ANOTHER scene component as a child of that one and the position of it wont be affected by the rotation of your character

[neat sinew]

OH

MAGIC

[brisk badger]

yup

[willow gate]

Good morning smart people! I have an issue where I set a bool on an actor component (inventory component) to true when an item is successfully added and false when it can't find an empty slot. I'm running the add function via a server RPC on the component whenever I interact with an equipable actor. I wanted to use that bool so that I can try to place equipable items inside my player's hotbar and if that fails, try to place it into the player's inventory but when I try to get the bool, from the actor being interacted with, it always returns false. Any ideas why that could be happening?

[lunar sleet]

Well you mentioned RPC so you might have a replication issue. You can show code here but might be best to put it direclty in #multiplayer

[willow gate]

hmmm.. good point(s). Hard to post code because of the routing but I'll do my best

[lunar mulch]

Heya, im trying to make an Animation Notify that stops input when the Notify is triggered inside the Animation. Any idea why this code isn't working?:

[lunar sleet]

Are either of the casts failing?

[lunar mulch]

Nope, i added a print string to cast failed earlier

Im not sure what im missing, is there anything else i could take into consideration?

[lunar sleet]

You have 2 casts

One is pure for some reason

Set a breakpoint and check if the code is going as intended

[sonic meadow]

Hi everyone, I am very new, working in the VR template and I want to create a trigger box when the virtual player enters a text and/or image is displayed.
To which I need to create an event? To the widget or to the trigger box? How to link those together please

[lunar mulch]

Hehe yeah your righti t's not casting succesfully from cast to player controller

Hmm..

[lunar sleet]

I’ve never seen that get controller from actor, usually it’s get controller or get player controller

Are you using enhanced input or the deprecated one?

[lunar mulch]

Enhanced input yeah

[lunar sleet]

You don’t need to disable input you can just remove mapping contexts

But get the player controller properly

If it’s single player just use get player controller and cast normally

[lunar mulch]

Im trying to make it MP viable, any thoughts on what i could do instead of the Get Controller from actor?

[lunar sleet]

Get controller

Then do a normal cast

If it fails you’re probably not possessing it properly or it’s an AIcon

[lunar mulch]

Hmm, i tried this : not working either (I thought this was what you meant with a normal cast). I guess im just being a dumbass, can't seem to get it to work

[lunar sleet]

I meant not pure on the controller one, the character one was fine

And again I’d just remove the mapping context

If you use disable input, do it in the char itself not the controller

[lunar mulch]

Alright ill go ahead and try that, thanks for your patience bud

[zealous moth]

I made an array string sort function in BP however I am stuck on the case where you get

ABC_10
ABC_2
ABC_3```
How would you make 10 go at the end?

https://blueprintue.com/blueprint/9r4lp20m/

[gentle urchin]

Guess you could just sort by generaø øength aswell

[zealous moth]

oh... let me see

[frosty berry]

For projectile collision detection, is it better to use the static mesh collsion or use a collider in the blueprint?

[zealous moth]

@gentle urchin I thought I was already doing it at the start when checking for the len of the string

[gentle urchin]

Idk, maybe? But 10 would be longer than 1 ^^

[zealous moth]

yeah trying to wrap my head around it

[potent dome]

Split on _, cast to int, compare if the left side of the split is equal?

[lunar sleet]

There’s an FArray:Sort in cpp btw

[lunar sleet]

Depends on how accurate you need it to be (simple/complex)

[zealous moth]

i know, got lazy

[lunar sleet]

This just seemed like more work hehe

[zealous moth]

ironically @lunar sleet the cpp sort does the same thing

you will see 1_10 before 1_2

[viscid root]

How would I go about getting the offset of the nearestPoint of a boxbound (local) and set it to an Offset Vector?

Struggling on getting the correct math. This is being used for my targeting for my ai.

[grave relic]

If you have any that would be very appreciated. Sorry for the slow response 🙂

[frosty berry]

I did not use a capsule collision and just depend on the meshs complex collision, but shots hitting the mesh from above dont seem to "collide"

[lunar sleet]

Does it work if you add a box collision?

[lunar sleet]

Ah i c what you mean

[zealous moth]

it's technically correct but that just breaks the way i named my maps

I can always add a 0

010
002

but i'd rather not redo it all

[stuck sentinel]

Im trying to make my third person character first person by placing the camera inside his head but when i look down or up it either goes into the ground or in the sky can someone help?

[lunar sleet]

That’s what I was gonna suggest next hehe

[loud tree]

I'll send it in dms cause idr if we can post yt links here

[stuck sentinel]

anyone?

[lunar sleet]

Your only other options are compare them as ints or use a length check before sorting… from what I see on StackOverflow this is a common issue with array sorting

[lunar sleet]

What do you mean by this

[faint pasture]

The static mesh collider already IS a collider in the blueprint, use that

You can edit the collision for any mesh if you don't like whatever it defaulted to

[faint pasture]

CameraBoom collision probably

Turn off the collision test

Or just lose the boom l

[dark drum]

You can get the last '_' (underscore), then get the numbers after and automatically add leading 0's if needed.

[lofty rapids]

or sort based on number instead of string if they are all the same prefix and you can pull out the number

[stuck sentinel]

when i look up it still goes back

[dark drum]

You should look at the physics asset that's used for skeletal meshes. You can disable collision on the capsule and enable collision on the skeletal mesh. If a physics asset is setup, it'll use the collision as setup in that. (Make sure to disable physics/gravity on the capsule or it will fall through the floor)

If you want the character to move again, re-enable collision/physics on the capsule and disable on the skeletal mesh.

[stark patio]

Does anyone kow how i could create an optimized system for storing and accessing player stats (not only the player needs to access the stats)

[dark drum]

Make a stats component that you add to what needs the stats. You can then get a ref to the relevant character (or event just actor if needed) and use the 'Get Component By Class' to get the stats component.

[frosty berry]

No, still no collision when hitting it on top. More investigation needed. 🙂

[lunar sleet]

Check your collision settings on both objects

[stark patio]

So make a component that references the player and gets + stores all the players stats (variables). Then give that component to the relevant actors?
Wouldn't doing this make changing the stats on the fly impossible?

[dark drum]

The stats would be inside the stats component not on your player character. It shouldn't need to know anything about what it's placed on.

[lofty rapids]

i just got into components, nice to be able to attach things to actors like that

[lunar sleet]

Modularity

[dark drum]

I use them for everything haha. Inventory, Stats, Interaction System, ItemPlacementSystem etc... I've used some off the market place as well for things like footsteps/footprints. There so much easier to work with.

I've even used them as a component that gets added to the game state for storing important level actors (using a unique name) so other actors can easily get them.

[frosty berry]

ShipMesh is set to BlockAllDymnamic and projectile is below:

[grave relic]

Does that mean that everything the player can turn into has to be a skeletal mesh then? And if I understood you right it wont be able to move while having accurate collison? 🙂

[lunar sleet]

How are you detecting the collision?

[lofty rapids]

show whats checked unchecked in your custom collision

[dark drum]

Yes. Alternatively, you could have your things they can turn into as pawn's instead of the full character and just place a static mesh inside. This might be a better option if they're going to be changing into something else.

[dark drum]

Is your ship the projectile?

[stark patio]

how would i go about updating the stats? wouldnt changing the stats from something like the palyer BP just change its own instance of the component?

[lofty rapids]

you want global stats or be able to have characters with stats ?

[dark drum]

Yes, the character Bo would get a reference to its own component and update the stats on it. The stats component would however have its own functions for updating the stats and it would just call them.

[stark patio]

So how would i go about updating the component for everyone? (sry this is like the second time i use components)

[dark drum]

If something else needed to update the players stats, you can just get the player character (assuming it's singleplayer) and then use the 'GetComponentByClass' node to get the stats component and call the relevant function.

[grave relic]

How would I set this up so it uses the mesh collision? Does it not use a capsule collision by default? 🙂

[dark drum]

You can set the capsule small so it fits inside your mesh. If collision is enabled on your mesh, you can get hit/overlap events from it regardless of the capsule.

[grave relic]

Okey, the thing is that I want them to be able to fit into certain spaces. So a small book might be able to use a dog door for example, but a lawnmower cannot. I should have made that clear, sorry 🙂

[stark patio]

The thing is what i need this for is so that status effects are able to change their damage depending on player stats and since a lot of enemies will have status effects on them i dont think this would be a very good solution

[dark drum]

You can scale the capsule to fit inside your static mesh.

[dark drum]

Why wouldn't it? The enemies can get the players stats and do the checks it needs before modifing the stats on the actual stats component.

[stark patio]

ahhhh now i understand how you meant, no you are right it 100% would i just misunderstood.

[jolly cipher]

Is anyone able to make this make sense?

So I created a mounting system, I basically attached my main character to my mount actor ( attach actor to Actor )
To handle the movement inputs I have forward my main character's wasd inputs to my mount and its working
I just cant seem to get the camera movement to work, as if its locked at 0 all the time.
My mouse movement does register to the mount and data is flowing correctly

Thee only way to get it working is to autoposses my mount to player 0.
BUt then I loose all my character's inputs and logic.

Anyone know why as soon as I attach my character to my mount I loose the ability to move my camera?

[stark patio]

thanks for the help!

[dark drum]

If needed, you could always incorporate those checks into the stats component if some enemies need to do the same sort of checks.

[grave relic]

Yes, but if there are cases like this, then a box that has the capsule collider can fit into spaces that would fit the capsule and not the box itself. If that make sense? 🙂 (red is the capsule collision). I Initially had a system like this, where I take the measurements and then scale the player capsule based on the object's capsule height and radius. But ran into this problem. Sorry that I'm asking so many questions, but this is really bothering me that I cant figure out something that seems so simple 😛

[jolly cipher]

Attached the video as requested 😄

[frosty berry]

no, a "laser" witha SphereCollision

[grave relic]

Clearer image:

[dark drum]

The object type for your ship shouldn't be projectile then. Also you'll need to make sure it blocks projectiles.

[frosty berry]

[willow gate]

Random noob best practices question: I have always been in the habit of having an art assets folder outside of my game content folder and then importing the assets to the project from the outside folder. I recently watched a seminar where someone just dragged and dropped textures and fbx files right into their project content folder, which automatically prompts for import, obviously. I just wanted to know which one of these methods, if any, is the best practice.

[frosty berry]

No, the ship is a staic mesh with complex collion as simple and the laser bolt is a separate object/bp. The laser should hit the ship

The ship is set to BlockAllDynamic

[brazen yoke]

As you can see the interface stays the same but the camera view goes black when the character is being moved on the platform. Anyone seen this behaviour before?
When I move the character normally with the controls it does not go black, aka its only when its on a moving platform. Its local coop so nothing to do with servers.

Thank you.

[timid tundra]

how to invoke parent or base version of the overridden function in blueprint?

[versed sun]

Right click node, Add Call to Parent

[zealous moth]

@dark drum it wouldn't matter, the onjly difference is the overall length of the string.

@lunar sleet I found this thread and it has an implementation but my loop stops at the first entry oddly enough
https://forums.unrealengine.com/t/how-to-sort-an-array-alphabetically/350158/7

hahahahaha nvm, same issue

[timid tundra]

I want to replicate the following code with blueprint.

AActor* APickerCppGameMode::ChoosePlayerStart_Implementation(AController* Player)
{
    TArray<AActor*> FoundActors;
    UGameplayStatics::GetAllActorsOfClass(GetWorld(), APlayerStart::StaticClass(), FoundActors);

    for (auto Actor : FoundActors)

            }
        }

    }

    return Super::ChoosePlayerStart_Implementation(Player);
}

However, it crashes when the number of PlayerStart actors less than the number of clients. What is wrong?

The C++ version works well.

Anyone see if Im doing anything stupid here! Im teleporting my character . then teleporting the physical parts and the constrained actors to them . If have a weapon in either hand they teleport correctly , But if the hands are holding the same weapon im running a check to find the primary gripping hand and teleport to that one,( ONLY i have an elastic band of the weapon returning to the constraints from where I teleported from. cant see why if they done match its fine but if they do its not.

[thin panther]

first off you probably want to feed the incoming player into the parent call

[timid tundra]

I just did but it still crashes with the following error:

Blueprint Runtime Error: "Accessed None trying to read property CallFunc_K2_GetPawn_ReturnValue". Node:  Add Movement Input Graph:  Follow Function:  Follow Blueprint:  BP_TopDownController

[lunar sleet]

May want to move this to #umg

[thin panther]

try adding a return after that parent call and feeding the output into it

thats the other thing youre missing from the cpp version

[timid tundra]

Well done. Thanks!

[thin panther]

np!

[timid tundra]

It still works even without connecting the Player pin.

[thin panther]

yeah it will, but we are trying to mimic the cpp version exactly are we not?

you aren't passing nullptr into that super call

[zealous moth]

@lunar sleet alrighty, i found a solution. Originally I had a datatable with all level informations including the name and it was ordered alphabetically. My string sorting was mainly used so that when you beat a level, you unlock the next and add the level name as a string in a save game array.
The issue is if you go to world 2 while world 1 is incomplete, you get weird "level_1_1, level_2_1, level_1_2" sequences.
The final solution was to use the data table, create an array and if my "saved game array" contains that entry, add it to a transient array and then set that as the new saved game array

Can anyone tell me if there is a real difference between using sphere overlap actors vs multi sphere trace?

[versed sun]

Sphere overlap will be 1 sphere
Multi sphere trace will be more of a Capsule shape

(a sphere at start , sphere at end, and connect them in the middle)

[zealous moth]

the usecase is different. Overlapping can be a 1 trigger event that happens once when something overlaps. Multisphere trace haas to be called. So unless you expect it to occur, you have to call it all the time

So if anyone knows the solution for above, Pls help me!

I don't mean overlapping the collision sphere of an actor.
I'm asking about the node called sphere overlap actors that Is called in the same manner a sphere trace is.

Hello guys I want to implement object pickup system. I already implemented Physics constraint, but it glitches out often and objects teleport around when near walls or the floor.

[lunar sleet]

Open the source code and check

Not sure what the diff in how they’re written is, but they usually have very different applications

[loud tree]

I don't really understand what the different applications would be because the multi trace for objects does more or less the same exact thing doesn't it?

[warped saddle]

Does anyone know how in widgets, make it so that the text in input text box after some length starts a new line instead of going on and on, llike wrapping text

I tried this but i does nothing

[lunar sleet]

Multi sphere trace makes multiple sphere traces from start to end location. Sphere overlapped makes a sphere around the target (self or w/e)

Hey all Im having a super weird issue where no montages at all are playing on my mesh. I made sure im using the correct slot, default slot and it is included in my animation blueprint. I have made sure that its not an issue with my current weapon being invalid as if i manually plug in a animation and remove the get validated check it still doesnt play.

Really unsure at this moment

[vital dagger]

I have written custom c++ function library calls. I want to use them in a BP Func Lib.
Some of them use BlueprintAsyncActionBase

I cant see any of the AsyncActionBase nodes. Are those not accessible from a BP func lib because of the async/different exec structure?

[loud cipher]

This is the case for all of my montages on my character

[lunar sleet]

What does that prove? Is it valid or not?

Did you put a print on the not valid exec

[loud cipher]

Yeah

I have removed that entirely

I have even tried calling play montage on beginplay with just a animation plugged in

no luck

[lunar sleet]

Did it print ?

[loud cipher]

No it didnt

There is no issue with the is valid

I made sure it has a slot and the slot is in the anim bp

[lunar sleet]

Did you use breakpoints to make sure your nodes are even firing at all

[loud cipher]

Yeah

[lunar sleet]

And, what happens, doesn’t reach play montage?

[desert juniper]

Is the montage variable populated correctly?

[loud cipher]

It does, the montage is called

[loud cipher]

What do you mean

[frosty heron]

Show your anim bp

[desert juniper]

Did you actually select a montage in that variable

[loud cipher]

Yes

[blissful grail]

You can see it...

[loud cipher]

Yes, i tried it with just manually plugging in a montage also

[frosty heron]

Make sure MM reload can be played by your mesh

[loud cipher]

Sure one second

[desert juniper]

You can’t. You see a variable. But not what actual montage it’s set to

[loud cipher]

Yeah they do

[blissful grail]

This is the most updated version of their code...

The asset is clearly selected

[desert juniper]

Oh. I see. I was basing it off first image

[desert juniper]

Which is why I said variable

[loud cipher]

Funny, it is now working on beginplay

But if i try call it through an input key

No chance, even using breakpoints and it fires it but doesnt play

Thats so weird

[frosty heron]

Which slot your montage is using?

[loud cipher]

Default slot

Wait sorry

Im using Upper body now

That worked on beginplay

But didnt work where i was calling it on reload input

[frosty heron]

Check your reload function, is it playing the same montage?

[loud cipher]

Btw the same problem is happening anywhere i call a montage to play

Sure one sec

[desert juniper]

Is it a multiplayer issue?

[loud cipher]

yep same animation

[loud cipher]

No im just testing in singleplayer right now

[desert juniper]

And it’s set to launch as the server not client?

[loud cipher]

What do you mean

No im launching in standalone

[desert juniper]

Interesting.

[loud cipher]

Weird i put a delay before calling the reload montage and it works

But doesnt work without the delay

[lunar sleet]

Begin plays don’t all get called at the same time. Where is your montage being set?

[frosty heron]

Looks like multiplayer issue

[lunar sleet]

Yeah that too

[loud cipher]

Same sequence

Multiplayer issues can still cause problems in standalone?

[frosty heron]

Gas use repnotify to play montages, I would probably look into it when I get to mp

[loud cipher]

All it is is just a montage being run multicast then run on server

[blissful grail]

If you're running this standalone, multiplayer doesn't matter

[frosty heron]

Don't know what goes in your macro, I would do a print string to check if the play montage node get executed at all

[loud cipher]

Yes it does

[gentle urchin]

Montage multicast what

[frosty heron]

When you said "work" in begin play but not when you press input make it sounds like mp issue but I can't tell for sure

Also not sure what you mean by multicast then run on server. That sound quiet wrong to me

It should be server call multicast rpc

I would personally play the reload montage locally, then call the server to do multicast rpc but exclude the local controller. (If not going with repnotify route)

[gentle urchin]

^ Sounds reasonable

also, avoid hardcoding values 😄

makes it hard to parentclass them and reuse existing logic

[frosty heron]

The delays here and there make it hard to debug too imo

[loud cipher]

Is there a difference between is valid and Validated get

[blissful grail]

No

[gentle urchin]

latter is a fraction of a fraction faster

[loud cipher]

Ok thanks

[zealous moth]

@gentle urchin 17% to be precise

[loud cipher]

17% faster?

[zealous moth]

last active 4 days ago

keep in mind discord is messing up these days

[lunar sleet]

He might just be taking a break

[gentle urchin]

I took 6 months last time lol

it was nice to actually get shit done

now im back here

xD

[zealous moth]

ew

why do anything

you got us! join us!

[lunar sleet]

This isn’t Slackers anymore

[gentle urchin]

True

[lunar sleet]

You have to work to stay close to the Source

[gentle urchin]

Struggling with implementing ongoing requirements for my quest system

feels troublesome

need a custom struct and everything

[zealous moth]

just add another bool to the array

[gentle urchin]

It doesnt fit with my current API

which forces me to extend the implementation parts of the system

which i dont like 😕

[versed sun]

I went with JSON for custom struct

[gentle urchin]

I want to maintain my system as simple as possible to implement ,

[versed sun]

but i also needed JSON for other things...

[gentle urchin]

so if i can stick to the current API , that'd be great !

I think i found a way tho

atleast, part of it

[spiral kite]

I can set crouched height but I cant set crouched width. how can I set it?

[versed sun]

Isn't it Capsule Radius?

[gentle urchin]

Yep

[quartz haven]

Hi folks! How do you create simple if statements in Blueprint considering the following?

I have integers 1 to 6 as inputs and I want to execute to 6 different outputs depending on the incoming number from 1 to 6. If I get 1, I execute on 1st output, if I get 2, I execute on 2nd output
Thank you so much!!

[gentle urchin]

Usually unchangef

[gentle urchin]

Switch on int

Then implement the ones you got

And put a print string in the default

[quartz haven]

And add 6 nodes, right?
LE: Ah. I can add pins. Super!

[gentle urchin]

To throw yourself a bone

[quartz haven]

Nice! Thank you so much!!

[gentle urchin]

Dont forget the bone part

[raw orbit]

is there a way for me to save a reference to a particular struct instead of just making a copy for it? in blueprints

[gentle urchin]

No

[raw orbit]

oh you sure? but it can be done in cpp right

[gentle urchin]

You can wrap it in a uobject and pass it around

Closest you get

[raw orbit]

hmm yeah

[tall field]

Is it possible to have functions in blueprint structs?

[gentle urchin]

No

[versed sun]

I think that would be more Data Asset

[tall field]

😮 It's possible to have functions there? Just trying to make a map from an enum to a function I'd run

[alpine kestrel]

how would one go about making 2D recoil / gun kickback? I am looking for some kind of function or way to move an object in a direction (xy), over a set period of time, possibly with ease in/out transitions.

[gentle urchin]

Lerp

[versed sun]

ummm.... a Map of (Enum and Function) ? no

[gentle urchin]

Dothing(enum) -> switch on enum -> do many things ()

[tall field]

Ah I see, thank you. Yeah I guess I'd have to go with the switch instead, thank you guys

[jolly cipher]

Ive been staring at my collision settings and not seeing anything that would force my character's camera.
Any ideas why I cant move camera freely after attaching my actor?

[radiant citrus]

what does this error mean?

[lunar sleet]

What are you doing there, #editor-scripting stuff?

[radiant citrus]

I am trying to construct an object from another class, where I store certain values

[lunar sleet]

What type of class is it

[versed sun]

I think Neo ment your Disabled Node

[radiant citrus]

the disabled node thing is irrelevant. it doesnt work enabled either

[radiant citrus]

where do I check

[lunar sleet]

I’m confused

[radiant citrus]

how do I see what type of class it is

[lunar sleet]

Are you not asking about the construct node?

[radiant citrus]

no I am asking about it

[lunar sleet]

I mean if you made whatever Tree nodes is you would know what it is, actor, actor component, widget, etc

[radiant citrus]

yea I made it a long time ago but I dont remember

let me see if I can find out

[lunar sleet]

Ok well what does it do

[radiant citrus]

save variables

arrays

[versed sun]

Are you constructing something and placing Self in it ? is that ok ?

[lunar sleet]

It’s an actor

You don’t construct actors

You spawn them

[radiant citrus]

oh

[jolly cipher]

I think I figured it out finally lol

[lunar sleet]

What was it

[radiant citrus]

okay but what type of classes do I construct

[lunar sleet]

Widgets for example

Stuff that doesn’t exist in the world

[radiant citrus]

but when I spawn the actor it asks about collision and stuff, but I only want to use it for storing data

[lunar sleet]

Just leave it on default

[radiant citrus]

okay

[jolly cipher]

Seems like a logic issue, I forgot I had added a branch where if I was mounted to redirect my look up and right input to my mount.
I miss understood the attach actor to actor function, I was under the impression that I had to redirect my movement input and camera inputs,
Turns out my character still has the camera controls, I just ended up removing my branch to redirect all my camera inputs to the mount. Seems like it was not needed lol

[short ivy]

How can i play a skeletal mesh animation on button press and when pressing again reverse it? It's for a skeletal mesh component in a pawn blueprint

[loud cipher]

Is it bad to run a lerp on a timer every 0.01 seconds on the server?

Aka are lerps and stuff bad to replicate

[thin panther]

Running a timer every 0.01 seconds is bad

[versed sun]

One way:

[fiery swallow]

Respectfully, ou should probably go a little more in detail with that

Because I can't really say I agree

[short ivy]

yea but which animation node do i have to use?

[thin panther]

Well more that it's pointless. You're having a tick with extra steps at that point.

Not to mention you'll be having it execute multiple times a frame which you probably don't want

Timers aren't meant to be running this low

[fiery swallow]

epic has directly stated it's better to use a very short timer over tick for example. i could probably find the video

[gentle urchin]

At 16ms youll get 1 call(16ms) -> 2 calls (32ms) -> 1 call (48ms)

[versed sun]

My Bad, was thinking timeline for some reason...

[blissful grail]

And they also say the Child Actor Component is fine. As well as Hot Reload. Their word isn't gospel

[thin panther]

It isn't though.

[fiery swallow]

"Let him get up, let him get up"

[versed sun]

Can you get current animation position/frame ?>

[short ivy]

right now i am doing this and the animation for the reverse is just a duplicated one with scale set to -1 to make it play backwards

but the problem is it's not reversing really, it's just spawning back

like in an instant

[fiery swallow]

this discord also says hot reload is not good, but I've been using it for months and never once had a problem

[short ivy]

how so?

[gentle urchin]

Take cover

[fiery swallow]

anyway, I think 0.01 second is fine, You should profile and find your results that way

[thin panther]

You purposefully turned on hot reload

....

[blissful grail]

"I haven't encountered a corruption yet, but these thousands of others have, they must be wrong"

[fiery swallow]

what is it, live coding or something?

[versed sun]

I dont remember animations , its been years

[fiery swallow]

source control?

[blissful grail]

Hot Reload is dog trash
Live Coding is better

[thin panther]

Live coding is not hot reload

[short ivy]

alright thx though, now that i know it's an animation issue i will ask there

[blissful grail]

"I like losing work. It is what makes me feel alive"

[fiery swallow]

They've both been called trash repeteadley

[fiery swallow]

Did you come to just be petty? You got nothing better to do?

[gentle urchin]

Plus the double execution when the timing's just right

[blissful grail]

Source control is obviously a solution. A better solution is to not corrupt your assets

[thin panther]

Not really. Live coding's usefulness is debated because it does normally result in eventual temporary corruption that needs an editor restart

[fiery swallow]

What I'm saying is you should profile, something like 0.01 seconds ona timer isn't really an issue and will probably never be a bottleneck. But I see some of the points you are making

like always, it depends what you do with it

[loud cipher]

Hmm okay that makes sense

[thin panther]

Just because it isn't a bottleneck doesn't mean it isn't bad lol

[blissful grail]

It's not about being a bottleneck though. No one said anything about that part.

[thin panther]

You can get all actors of class everywhere reasonably fine in a lot of situations but it's still not great

[gentle urchin]

You sorta dont know what fps the game will be running at

Low timers can make bad performing laptops perform even worse

[loud cipher]

Also guys, lets say for example i have a crouch system, and i want to update the crouch animation. Is it better to check if the player is crouching every update of the animation blueprint, and then promote it to a variable to then use in my animation states, or is it better to directly from the player bp, cast to the anim bp and set the variable to true from inside my player bp

[gentle urchin]

Due to multiple executions within the single frame

[fiery swallow]

He asked if something was bad, 99% of the time, people are coding in a way that is not good. I think there's a serious problem with being so nit picky here

[gentle urchin]

Compared to tick.. which atleast limits to 1

[thin panther]

Not to mention the whole, not discarding calls but instead executing multiple times a frame to catch up

[gentle urchin]

My point exactly ^^

[thin panther]

This ain't a nitpick lol. It's bad. End of story.

[blissful grail]

You help prevent people from continuing to code badly by not perpetuating bad practices.

[fiery swallow]

Whatever you say

[thin panther]

I mean if you want to make your own bad code writing habits with unintended behaviours you can go ahead but don't fight the people that advise against it

[fiery swallow]

As someone who has been a tutor/mentor for 6 years. I will trust my gut, and focus on helping people release things. Rather then over complicate nothing.

It's really not this serious though

[loud cipher]

even if the timer is going to be cleared after a second?

[gentle urchin]

Tick is probably the biggest badboy still said to be bad in general

[loud cipher]

What if you dont want it to be called every single frame and just for a few seconds only

[thin panther]

The timer is overcomplicating it lol. How hard is it to drag off event tick

[gentle urchin]

Atleast as far as online tuts go
