blueprint

[indigo stratus]

I know what you mean, but I don't want that.

But thanks anyway

[marsh pilot]

Hey all, looking for some generalized help on how I should organize my resources data for a banished-like game. I have a struct of what each type of resource has, then I have a data table of that struct, and then I have an enum for each row name from the resource data table. Lastly, in the building master I have a map of that enum where the float is the amount of that resource in the inventory (or needed to construct it). Let me know if there's anything I should do to streamline this

[thin panther]

That data table is going to cause you issues btw
You've fallen into a classic trap that a lot of tutorials teach.

That is, hard refs in a data table.
When you reference one row of that data table, all rows are loaded, and all the dependencies. Meaning just by grabbing a single row, you've loaded every icon, every mesh, and every material, and every texture that anything in that table relies on. Move to soft references

[gaunt stirrup]

does anybody know how to change an image in a widget on a button

[marsh pilot]

I'll look into this, thanks!

[gaunt monolith]

I've followed this tutorial to get a day/night cycle going with the sun position calculator https://www.youtube.com/watch?v=Zg2NaZcyAjk . Could anyone point me in the right direction to be able to add the day and time updating on the player widget too?

[kind prairie]

Hi everyone! I hope someone can point me in the right direction. I have a third person project using the default template. I have a blueprint for a ball, where I have a sphere as root component and has physics enabled. The ball also has logic to increase the scale based on distance moved (think like a snowball growing bigger)

what I want is upon event trigger, have the player and ball snap to each other so that while moving, the ball still remains in front of the player (with physics still enabled on the ball). I have tried to attach the ball (but that doesnt work with physics). I also tried physics handle. I managed to kind of get something working with that, but I dont feel it is the correct approach? (I might just be using it wrong haha). I also gave a quick look to physics constraint, but I had better results with physics handle. I feel there should be a simple way to do this and I am just completely missing it haha. any help would be greatly appreciated!!

[small coral]

you could try something like this

Select the texture you want to change it to

[nocturne river]

I am trying to find out how to freely deform models in UE5 according to game play, but I am having trouble figuring it out.
To simplify and specify what I want to implement, I would like to move one vertex of an object in response to key inputs in the game. For example, when the player takes a step forward, the vertex should move forward by the same amount.
It seems that it is possible to move an entire object using the Geometry Script, but I want to be able to move just one vertex to deform the object.
My ultimate goal is to create a game that deals with 4-dimensional objects, so I need this knowledge. Alternatively, if you know any useful methods for dealing with 4-dimensional objects, I would greatly appreciate it if you could share them with me.
I apologize for the beginner's question, but thank you in advance for your help.

Note: This question was originally written in Japanese and translated into English using GPT (Generative Pre-trained Transformer).

[dreamy mountain]

anyone?

[thin panther]

You might want to check up with #geometry-tools for specifics, however I know certainly you can manipulate vertices with geometry script. It may be involved, and you may need to build the mesh from scratch, I'm not 100% sure on whether you can manipulate a specific vertex on an existing mesh. Geometry script definitely sounds like the right start though. I can't think of any other way you would approach it without making a custom system, or using something deprecated, like the procedural mesh component.

Also, wow, GPT is really good at translation, at least from Japanese to English 😆

[faint pasture]

physics handle is correct

Make sure not to over-constrain the ball.
Only constrain on X and Y, leave Z free, and all rotation free

[hidden cape]

I guess no one has an answer to my question?

[kind prairie]

I did get better results with physics handle in terms of the ball rotating as I am moving it. But I was not able to set X Y Z constraints in the handle, that I could only do in the physics constraint. For the handle there is just toggles for linear and angular constraint, which enables the damping and stiffness options.
So the fact that I cant disable constraint on the Z axis, means the ball goes with the player if jumping (not end of the world, might just disable jumping when pushing the ball).
I have a location set infront of the character, which I constantly use to set the target location, and use high linear stiffness to keep it there. is this the correct approach to set the location?

[faint pasture]

That can work, or maybe you can use a constraint component and it'll give you more options

physics handle uses a constraint under the hood so it's all the same really

[kind prairie]

if that is the correct approach to setting the target location, do you have any suggestions on how to modify that location to accommodate the growth of the ball. ( I will share videos now to show what I currently have)

[faint pasture]

You'll probably have to do some math

I'd just make sure it's not too stiff so it can move around a bit

[kind prairie]

I was not able to get the rolling working as smoothly with the constraint vs the handle. but I might need to do a deper dive on the settings

[faint pasture]

I bet if you made it stiff enough such that when turning left and right it lags by like 15 degrees, and did a bit of math to make it not suspended in the air or shoved into the ground, it'd work pretty well

[kind prairie]

is this now with the physics handle or physics constraint?

[faint pasture]

handle

would work for both tho

handle is basically a wrapper on constraint that doesn't let you split out your XYZ limits

[kind prairie]

here is a preview of what it looks like when grabbing the snowball. The box infront of the player is what I use to set the target location for the physics handle. it remains infront of the player, but the rolling isnt perfect (might just need to adjust some settings)

and this is the stiffness and damping settings

and here is a preview of the ball growing with distance moved (not being grabbed here). I need then to find a way to accommodate this growing size, to set the new target location, so that it remains x distance in front of player, but also doesnt float or clip into the ground

[trim matrix]

the model looks dope!

[gaunt stirrup]

okay thanks ill try this

thanks ❤️

I want to chain two characters together, meaning that one character moving further away from a player will eventually drag them with them.
**Use cases: **

1. If one player jumps down a ledge and the other one doesn't, the one who jumps should hang over the ledge.
2. If the player on the ledge moves further away from the ledge, they will eventually drag the player up

Does anyone have any pointers, tips or guides on how you would accomplish something like this? I found this game Chained Together on steam, that seems to do exactly what I want: https://store.steampowered.com/app/2567870/Chained_Together/

does it add to the next one ? or does it keep putting it in the same spot ?

[dreamy mountain]

when i get a different perk, it adds the second one to the first slot

ill put 5 in a row and show you, hang on

each machine has a perk id, but no matter which you go to, it gives that order of perk

-- perk machine bp --
https://i.vgy.me/J4L40n.png - perk machine
https://i.vgy.me/yyHDRv.png - buy perk
https://i.vgy.me/e88wlx.png - new perk
-- moves to widget bp --
https://i.vgy.me/s0fNZc.png - AddPerk
https://i.vgy.me/flcThe.png - is perk slot available
https://i.vgy.me/fhwQuS.png - get perk icons

@lofty rapids thats all the code involved in it, should help with fixing this, because ima be honest, sat doing this for a few days, its been broken for the past few and i just really want this done and fixed lmao

[lofty rapids]

in this enhanced input action in your cube bp ?

[dreamy mountain]

yes

[lofty rapids]

probably not a good spot for it, you probably want that on the player

[prisma tree]

Hi, sorry to interrupt. How can I check if a variable has any value/content in it?
I want to check if the variable (object) has a savegame blueprint in it. If not create a new and if it does continue:

[dreamy mountain]

its only there because i had an issue with buyables where you could buy something from like miles off, so went with this to fix it, dk if theres an easier fix

[lofty rapids]

are you always going to use cubes ?

by that i mean the same bp ?

[dreamy mountain]

yep

its one blueprint, with that perk id changable per machine

[lofty rapids]

think about the input action (i'm surprised it even fires), but for each block it will fire most likely

[dreamy mountain]

1 - wonderbarr
2 - magic fingers
3 - barraidaide
4 - tutti shooti
5 - 1-up soda

[lofty rapids]

when you overlap set a variable on the player like interactactor

then when you press the key check if it's valid

but do in the input on your character or player controller

so when you hit the key it only happens once

thats mostly a problem idk if it will fix everything but it's a good start

[fierce timber]

Hey,

I am currently working on creating a rebinding menu using user settings from the Enhanced Input Subsystem. I want to develop a system where each user can customize the trigger type, modifier key, and key binding for each action. To achieve this, I created a custom input trigger with multiple options, including:

Modifier Key: None, Left Control, Left Alt, Left Shift
Trigger Type: Pressed, Pressed Continuous, Released, Hold, Hold Continuous, Hold Reset, Double Click
However, I am facing difficulties in allowing users to change the modifier key or trigger type in the user settings; currently, I can only modify the key binding itself.

Any suggestions on how to resolve this issue would be greatly appreciated.

[dreamy mountain]

it already only happens once

thats what the buy perk does, it checks if you already have said perk

[lofty rapids]

i'm saying the enhanced input action

think about it

you have it on multiple actors

i'm surprised it even fires on a random actor

but it's most likely going off multiple times

for the amount of cubes you have in there

it's not specific to when your overlapped

just the way i would do it is put an interactable actor on the player as a variable

[dreamy mountain]

i have an interactable variable

[lofty rapids]

if you invalidate the variable by setting it to none, the when you hit the key you check is valid

[lofty rapids]

i would also use started

[lofty rapids]

and i'm assuming interactable is false by default ?

thats such an odd way to do that

[dreamy mountain]

yep

[dreamy mountain]

how so?

[lofty rapids]

because your triggering all the events and checking a variable

instead of triggering it once

[dreamy mountain]

why overcomplicate it when this works, but this isnt the issue

the issue is that it displays the wrong perk

and skips over a slot

[lofty rapids]

does hello print more than once ?

i'm guessing 4 times ?

[dreamy mountain]

nope

it prints when im in the box and press f

which is my input action

where it fires off the following
hello
1
2

• press f again
  hello

ok, i fixed one issue, being the perks not giving me the right one, now its just that skipping of the first slot

[lofty rapids]

make sure your array is organized properly

maybe perk2 is supposed to be perk1

try to flip them see if it works

[dreamy mountain]

it was

fml

thanks for helping though, i wouldnt have thought to check that

[untold ivy]

Alright, for one of my smart objects I need a Box (Fbox)
For test, I managed to make it work by using my current actor's position.
My game is taking place in a shopping mall. I would like, when an NPC gets in front of a store, he looks for smart objects to interact with within the store.
My issue: How can I associate a particular box (or set of boxes) with an entry point to pass it to the action?

[dreamy mountain]

not related to your issue, but just out of curiousity, what is your game about? a game in a shopping centre seems like a neat idea

whats the code look like?

[fresh ice]

[lethal ocean]

Hi! For an endless runner project I have a main floor blueprint that gets repeated. It contains an audio component, but it only plays on the first instance of the floor. As soon as I start running across the platforms, the audio disappears. Is there some settings I am missing or something?

[lofty rapids]

so you have an audio compent, and it plays on the first one, but doesn't play when you spawn a new one ?

[frosty heron]

Why can't you do the logic on overlap? Is your game fps or tps?

[untold ivy]

TPS. On overlap? meaning?

[frosty heron]

Tps stands for third person shooter

Fly stands for first person shooter

What sort of camera style are you using.

[untold ivy]

I know TPS and FPS. It's overlap I'm asking about. What do you mean "by overlap"?

[frosty heron]

When the character overlap with the box, a reference can be passed. So what stops you from interacting between the box and the player.

I don't think you need to check distance with the player as well imo.

[brazen pulsar]

I'm having a bug with an individual level transition instance. I've got like 7 in the level, but this one and only this one is uninteractable. doesn't even notice when the use command is sent to it.
Is there any kind of instance bug possibility? Does that happen?

[frosty heron]

Debug

[brazen pulsar]

how?

[frosty heron]

How to debug?

[brazen pulsar]

yea, also what

[frosty heron]

U can use print string, find out the root of the problem

If your interact never get called, find the caller and keep working your way up

[brazen pulsar]

No, the interact gets called, it's just that it's not getting sent to this specific instance. If it was getting there, the debug string at the top of the bp would print when it hits it

But it's not

[frosty heron]

Again work your way up, make sure interact gets print in that instance? How? Again work your way up. Check the collision setting etc if you are interacting with a trace or check your overlap.

Make sure that instance have the right collision etc for the interact to trigger

[deep lagoon]

hey
looking for some deeper insight on how to best manage sound for character

eg pairing sounds to discrete behaviors
ex i have a charging enemy that plays a sound for that charge

what are some best practices for managing sounds like that
preserving audio components vs respawning and destroying them?
when should i think about a higher level sound manager component etc?

realized i'[m just defaulting to managing each possible sound in parallel and that feels sub-optimal

--can't really find any resources on this subjecft

[untold ivy]

Oh, no the box thing was to test it. It was what the tutorial on Smart object did. I'm now trying to go outside the tutorial and make preset "areas" and have NPCs interact in there. It's not going to be the player. I was mostly asking about the clean way of remembering "areas".

[broken wadi]

Since my game is multiplayer some sounds needs to be heard by others so I spawn them (along with any particle effects) using a multicast. For sounds that play for the local player only such as when the character doesn't have enough stamina to perform an action it doesn't need to be heard by other players so I just play an audio component that's already on the character. I also have level placed sounds that run continuously in the background.

Using audio components attached to the character or having one-off sounds spawning in with auto destroy doesn't really matter all that much for performance as far as I can tell. I think its best to make use of whatever management / organizational system that works well for you. Also maybe try asking in #audio you might get a better answer there.

[dreamy mountain]

hey so im trying to do a like delay between attacks, but only while the player is in the attackrange box collision; how would i do it without causing an infinite loop and crashing ue

[broken wadi]

I solve this by using Set Timer By Event. Also the Process Damage event in the screenshot does a bunch of gameplay logic to damage amounts etc... but for your example you can just replace it with the Apply Damage node you already have. @dreamy mountain

[dreamy mountain]

i tried to adapt it because the enemy is only damaging the player but it didnt work, is the overlapping actors array you have that important, or am i just being an idiot
@broken wadi

[broken wadi]

Just replace the array with a single actor, should be fine then. The get overlapping actors node you have isn't necessesary because you already have done that step with the On Begin Overlap.

[dreamy mountain]

ah ok

[quartz flare]

How do you play only one section of a montage? I see there is a "Starting Section" but then it just continues playing my following sections.

[dreamy mountain]

i got it working, thanks lawlster

do you also happen to know how to add a delay before triggering a natural heal after the player takes damage?

thats my health system, and it gets called on event tick

its in the player bp

[spark steppe]

don't use health != max health

use health < maxHealth

[broken wadi]

Instead of using tick, on the Event Begin Play setup another Set Timer By Event with 0.5s loop. Then you can call your health regen event. Also you can use a negative number on the Apply Damage node to for healing.

[spark steppe]

otherwise it's likely to bite your butt considering floating point precision

[dreamy mountain]

oh really? thats neat, didnt know that

[spark steppe]

or use nearly equal -> not

[broken wadi]

That way you don't have to constantly check the stuff before the delay every frame since you only want to apply a small amount of health 0.5s anyways.

[quartz flare]

Doesn't appear to be possible so I just tweaked the Animation Segment start/end time and got rid of my sections

[frosty heron]

Yes it's possible

Loop it

Set the next montage to it self

[tranquil lagoon]

Is it possible somehow to ensure a constrained component actually attaches to the Physics Constraint location? Everything works perfectly when I set the contrained component at runtime (using a trace) except for one thing, and it's that it leaves this massive gap.

[quartz flare]

The "Next Section" tag is read-only in the editor. There are functions to set the next tag in BP/code

[frosty heron]

You go to your montage asset, look at the montage section. Find the section you want to loop, select the tick box and select the section again. The section will have diff color

I do it all the time.

You are not looking at the right place, I'm not talking about abp node

[quartz flare]

I am in my montage asset, I am able to add sections but they automatically set their next section to the one that follows in the timeline

[frosty heron]

Again you can modify them

Keep trying or look up on the internet

I can't show you cuz I'm at work and no pc for obvious reason

Just read what was said above again if you lost

[frosty heron]

Not looking at the right place

The section would be in boxes

Eg mine will look like Default->punch-> dead

Where dead is looped

Selecting the tick box or w.e next to the dead box then selecting the dead section will loop it

[quartz flare]

oh I see a Montage Section window at the bottom right, let me try toying with that

lol that is a wacky UI. Okay, clicking the stop button and not setting it to itself but clearing it to None worked

thanks!

(looks like a stop button to me lol)

[stoic ledge]

the designer probably struggled for hours on what shape it should be and was like fk i guess a square

[tulip karma]

Assuming a 2d sidescroller, if I spawn a projectile in a blueprint, how do I properly set its initial velocity? At the moment when I'm facing left the projectile shoots to the right still, due to initial velocity being set to 1000 in the x-axis. If I try and spawn it then set the velocity with the return value from Spawn Actor it doesn't move at all, so I assume I'm missing an extra step, or approaching it entirely wrong... Any suggestions?

[stoic ledge]

x2?

[tulip karma]

Is that for me sorry?

[stoic ledge]

@tulip karma i misread what you were saying a bit, i feel that you set the velocity but isnt updated correctly

[tulip karma]

Yeah, that's my feeling, just not sure where atm ha

[stoic ledge]

assuming the projectile actor just spawns and starts moving from some initialization method. is velocity inherent variable in the actor class?

[tulip karma]

Just found something about deferred spawning that might be what I need

[lofty rapids]

also i would think rotation would matter, maybe just rotate it when you spawn

have not worked with projectiles much but it's a thought

[tulip karma]

That's not a bad shout, deferred spawn doesn't seem to be available from blueprints anyway so I'll take a look

[lofty rapids]

try to set like 180 in the spawn

[tulip karma]

Yeah, no idea why I didn't think of that earlier D:

Balls, it rotates the sprite but still shoots right, guessing it's that initialVelocity still D:

[lofty rapids]

is it a normal projectile ? or like mentioned whats going on with the shooting ?

[tulip karma]

Yeah just an actor blueprint with the Projectile Movement component

[magic parcel]

Anybody know why this might be happening:

The first montage plays fine, the second one plays, but it never goes to the completed pin, or the blend out... it only goes to the EXC pint (top one)

[mortal hamlet]

Anyone know how to disable character movement when crouched?

[magic parcel]

The issue is, if I use the EXC pin, it does not care how long the animation is and just moves to the next node

[dim siren]

Show code? It sounds like you're spawning the projectile with a world space vector rather than one relative to the player.

[magic parcel]

if I set the blend tree up, it will repeat from the EXC pin, and every time after that it runs fine with no problem

[tulip karma]

It's getting the initial transform from a socket location so I think you're right there...

[magic parcel]

with a state machine, and inside the crouch state you turn off movement via the movement component... or.. you can make a root motion animation and use the root motion to control the location

[dim siren]

Assuming your character actually changes axis when turning left, you should be able to convert the vector from world space to local space.
I don't have experience with 2D in Unreal though.

[tulip karma]

This is how it looks ingame

[tulip karma]

I'll see what I can come up with

[lofty rapids]

so here when you change bullet rotation to the opposite, it only rotates the sprite ?

[tulip karma]

Yeah exactly

[dim siren]

You can try using an Inverse Transform Location node.

[tulip karma]

How would that work sorry?

[mortal hamlet]

any tips with doing using the movement component, i cant make animations or do anything with root motions

[magic parcel]

Create the state machine in the animBP

from there, create the state (crouch)

in the crouch state... pull the characters current speed and set to 0

so, while they are in that state they will have 0 movement speed

So, it goes from exc pin -> interrupted (no clue why, as I have done nothing with the code at this point) -> back to exc (where it stays and does not go to completed or interrupted agian)

[dim siren]

Just to verify, if you turn your character, does the rotation/x-axis change too if you print string it? Or does the socket transform remain the same?

[tulip karma]

Socket transform stays the same :/ it uses the scale to change the direction the sprite faces

[dim siren]

Then that's probably part of the issue, as the projectile will always spawn with the same transform.

Not sure how to solve it though, sorry 😛

[tulip karma]

Interestingly even if I break the transform apart, set all the rotation values to 180 and then log that out, the rotation is still 0 🤔

[dim siren]

You could change the transform location depending on the scale I suppose. So if the scale is -1 or whatever you use to flip it, you can inverse the x-axis when spawning the projectile.

[tulip karma]

That's exactly what I was attempting 😄 wrong screenshot derp

[lofty rapids]

does the bullet have anything on beginplay that may be making it go that one direction ?

[tulip karma]

Only the InitialVelocity that's set in the x axis but that's not in beginplay it's part of the projectile movement properties

[obtuse kraken]

How does welding components when attaching them work? Having some issues with it.

[tulip karma]

If I set the initialvelocity to -1000 it always goes left, set it to 0 and it just stays still because there doesn't seem to be a way to set the velocity after spawning

[stoic ledge]

@tulip karma "You need to create a Float var (Ball Speed) in the projectile class. Set it as instance editable and exposed on spawn. Next set its default value to your absolute minimum speed. Save.

Open the construction tab. Drag the projectile movement component (PMC) into the graph. From it drag out and Set Initial Speed and Max Speed. Use your Ball speed as the value.

Now you can dynamically set your ball speed on spawn. The Spawn Actor of Class (your projectile) will now have a "Ball Speed" pin. So calc the speed and pipe that value to the Spawn actor node."

~Rev0verDrive

[tulip karma]

I'll give that a look in the morning, eyes are starting to dry out now D:

Thanks for the info

[halcyon flower]

Hello again, I have an actor with a component on which holds stats and information and I was wandering is it possible to get the components variables without spawning the actor? This is for a vehicle shop and I want to show the stats like top speed, acceleration, power and more without spawning the vehicle actor similar to Forza. Because I use a component I cannot just get the class defaults but I want to use this component so I can use it with other vehicles like helicopters and bikes.

[lunar sleet]

Use a Data Asset

[halcyon flower]

Would I have to make one for every vehicle

[lunar sleet]

Yeah I believe so. There’s also DataTables which can hold multiple rows

If it’s just values you can prly store them all in there

[halcyon flower]

But if I were to make a change in the actor I would have to also change it in the data asset or table

[lunar sleet]

If you’re making a change in the actor, I’m guessing the actor is spawned by that point

[halcyon flower]

I meant in the editor like changing the top speed to balance a game

[lunar sleet]

Well yeah but you’d only need to change it in one place, provided you make the actor take its values from that storage

[halcyon flower]

Oh ok, I never thought of using it that way. I thought data tables were just to reference data

Thank you

[mortal hamlet]

do you have an example of what that would look like? ive only just gotten all my character stuff put together and working properly over the course of a few weeks and many different tutorials

[magic parcel]

sadly, no. I am an artist by trade and only fiddle. I know how to make things work (in theory) but actual application of doing so... not so much

I have been playing with this damn blend tree for 5 hrs now..lol

something my coder could do in seconds lol

[mortal hamlet]

fair enough, i just put the blendspace together instead of my other one which i kept, this project im currently working on is practice for my later project, i just need to figure out how to disable movement when my character is crouched, then i have some more animations to implement

[magic parcel]

make a crouch state and put this inside there

how to get those to the result node... no clue

but this is how you set the speed 😛

[mortal hamlet]

ah mine is a much different look lol

[magic parcel]

some people like uber complex ones 😛

[magic parcel]

so... with this setup

you could never go from jump to crouch

or from crouch to jump

without going through idle first

[mortal hamlet]

No, and its done like this on purpose

[magic parcel]

I suppose, depends on the game I guess

in any case, the path doesnt matter

the logic is the same

in crouch start you would put the nodes I showed you

[mortal hamlet]

its based off of an older game, battalion wars to be specific

[magic parcel]

and in Crouch end, you would put the same nodes, but with the normal values you want

[rugged merlin]

This question probably gets asked a lot, but I haven't been able to find anything quite matching what I'm asking specifically.

I have a project where a component will be fired using a projectile and I want there to be different behaviors depending if the thing it hit implements a specific interface. What is the best way to check whether the component being hit is an implementation of that interface? Is there some way I can use casting to tell?

I intend to use the OnComponentHit event unless there is a better one

[frosty heron]

The node to check if something implement interface is "does implement interface"

You shouldn't really need to cast if you are using interface. That totally defeat the purpose

[rugged merlin]

Would I still need to cast if I then want to call methods from the interface using that object after verifying it?

[frosty heron]

U gotta make up your mind first if you want to use interface or cast.

Interface is used when you have common function for classes that doesn't share the same base class.

If u are going to use interface, just plugin the object to the interface

Eg hit actor -> interact

No casting needed

[rugged merlin]

When I try to connect the pin it doesn't work

The only way to make it compile is to use a cast

[frosty heron]

No that's just misunderstanding on your part. Show your bp

[rugged merlin]

How else do I get the thing I want to call the method on

[frosty heron]

That's not interface

If you want to use interface you want to implement the function IN the interface

[rugged merlin]

I'm trying to tell if the object being hit is one that implements the interface, and if it is, call the method it implements

[proud salmon]

When using soft references, for example, an animation montage.

Prior to playing the animation, I want to load the asset using Async Load Asset, correct?

If so, should I ALWAYS call async load asset or should I check if the soft reference --> reference is valid and only run it if not?

Image A vs Image B vs ??? (Is there another way I should be doing it?)

[frosty heron]

Then make a function in the interface . I_Grapple

Then in your grapple point bp, implement the I_Grapple function which execute the grapple function

[rugged merlin]

I did that

[frosty heron]

Then it's just on component hit, hit actor -> I_grapple

Not from the picture no you did not

[proud salmon]

Sorry, my second image made no sense 😂 This one. #blueprint message

[rugged merlin]

I did

For now I just want it to return true since this is a placeholder

This is in a different class, so I can't use self

[frosty heron]

You are not even dropping interface node. It's the one with the msg icon. Follow the instruction above

The picture u showed is trying to use grapple succesfuk in your bp grapple not the one derived from interface

[dawn gazelle]

In Unreal an "Interface" is a very specific thing.

What you have there is a function that is contained within a class.

To call that function directly, you must have a reference of that particular class or any of its children.

[rugged merlin]

No I have a separate interface that the class from that picture is implementing

[frosty heron]

Then call the interface not the function that live in your bp grapple

[dawn gazelle]

it says right on the node... "Target is..." which indicates its a function.

[frosty heron]

Hard to help if you are being combative

Get the node with the msg icon

[rugged merlin]

Is this what you mean?

[frosty heron]

Now you can plug hit actor or any object to the target

[rugged merlin]

Ok thank you

[dawn gazelle]

So you have an object and an interface known as Grapple Point?

[frosty heron]

I would suggest to prefix your interface with I_

[rugged merlin]

I have an interface called grapplable point and an object that implements it called grapplable cube

It only has the grapple successful method

And I wanted to call that method whenever the grapple hook hit something that implemented that interface

[frosty heron]

In your grapple cube, override grapple successful, add a branch and on true call what ever function you want

[rugged merlin]

Yeah this is what it looks like now

[frosty heron]

The does implement interface might be redundant btw depending on the context

Cuz if they don't implement it simply does nothing

[rugged merlin]

It's not because later that branch will also have a completely different thing happening in the false pin

[frosty heron]

But it's fine to do if u want to filter the code after the interface call

Ahh yeah that's fine then

[rugged merlin]

Yeah this would actually be very bad if it does nothing when it finds that it's not an instance of grapplable point

[frosty heron]

Soft ref is just a path to asset. You will have to load the actual object if you want to do anything meaningful with it.

[proud salmon]

Ya, I just mean. Do I need to do the "is valid" and not run through "Async Load" every time it's called, or does it not matter?

[frosty heron]

It won't be valid unless you load it at some point

[proud salmon]

Sure, but say I'm using the asset every 10 seconds.

Should I:
a. Check if valid --> Load if not --> Use
b. Load --> Use

I guess to put it another way, is there any harm in calling "Async Load" if the asset is already loaded?

[frosty heron]

No harm

It will just go to completed pin

[proud salmon]

👍 That's how I had hoped but wasn't sure. Thank you

[frosty heron]

Not sure about doing soft ref on animations tho, felt like micro optimisation

But I also don't know better

Right now the things I put on soft ref are material textures etc

[proud salmon]

ya, I went a little wild but I'm going to dial it back to things that make sense 😂

[frosty heron]

Everything that goes to my DT or DA I try to soft ref it. Can't afford any hard ref there

[proud salmon]

How would you go about loading a soft reference (static mesh) both in the world at runtime but also in the construction script when placed in the world?

Async load doesn't seem to work unless it's in begin play. Load Asset Blocking works but then it won't be async 🤔 Unless i'm misunderstanding

[frosty heron]

If u gonna load it anyway, there isn't much use to use soft ref. You load things that are on demand. Eg inventory info from data assets or DT

[proud salmon]

well the reference is stored in a data table

and then used when the actor is spawned

[frosty heron]

No idea with construction script

My experience is doing very minimal things there

Mostly setting anim leader pose and setting comp ref

[proud salmon]

Ya not sure the best way to go about doing this 🤔

I want to have a soft reference to the static mesh in the data table, as it could become a pretty big data table over time.

But I also want to be able to put the item that uses the data table into the world in the editor. But Async Load doesn't seem to work for that, so you can't see the item when you place it. Works fine when I hit play.

[graceful rampart]

Hey,
I am having an issue,

Whenever I possess an pawn Why does Possession moves Camera to default position? How to stop it?
Can you one help me out regarding this.

[rugged merlin]

Wait so you're posessing a pawn and the camera's acting weird?

[graceful rampart]

Yes

[rugged merlin]

Is the camera a component of your player class?

[graceful rampart]

No its default unreal camera class.

[rugged merlin]

Oh so it's a separate object?

[dawn gazelle]

Try unchecking this in your PlayerController.

[graceful rampart]

Yes its attached to the pawn (i.e my custom vehicle). When character seat inside vehicle I want to set vehicle camera at the position from where the player goes inside vehicle. But as I possesses the vehicle pawn camera goes to the default position

[graceful rampart]

I tried it once the vehicle is possessed it goes to the centre of vehicle

[rugged merlin]

So the camera is inside the vehicle?

[graceful rampart]

Yes, in the hierarchy of vehicle. The camera is placed at back of the vehicle.

[magic parcel]

Can somebody help me with getting an interp setup? I tried a timeline, I tried a set time by event... i failed all 😛

I dont know why it doesnt interp. The value switch worked

but interp...nope 😦

[dawn gazelle]

Interp requires a current and desired value. The current value must be updated each frame.

[magic parcel]

That is what the FInterp does, no?

[dawn gazelle]

It doesn't update any values. It just gives you an output.

[magic parcel]

so I need to inertp the value with a lerp?

[dawn gazelle]

If you don't give it the current value for this frame, then it'll always give you the same value output.

[magic parcel]

I thought that was the point of the delta time

[dawn gazelle]

In your example there, you'd want to plug in GetCurrentFOV into the current value input.

The delta time is just how miuch time has passed since the last frame.

It interpolates how much the value output should be based on that time and the two input values.

[rugged merlin]

Wait so what's the specific problem? Is it going inside the vehicle when you enter it?

[magic parcel]

I set a defaultFOV (current) at begin play. Which pulls the current FOV

that is 90

TargetFOV is 120

the switch happens, but no interp between the switch

so that is where I am lost. Do I use the timeline and alpha from there?

[dawn gazelle]

It needs to be fed a changing value for the current value.

If you don't have a changing value, you'll always get the same value output.

[magic parcel]

okay, that makes sense, but I have no idea how to do that (primarly an artist here :P)

is that where the set timer by event comes into play?

and then I use the update timer handle (variable I created?)

[dawn gazelle]

Interps happen over time.
If you want it to look smooth, you want it running at the frame rate, not necessarily a timer.

[magic parcel]

so, you are suggesting I put this on tick?

[dawn gazelle]

You can use tick or a timeline.

[magic parcel]

so I had a timeline, but again, I dont know where to put that node or hook that in

here I have added at timline, I will add a track called alpha and that will act as the interp speed

[dawn gazelle]

Current: Get Current FOV.
Target: Whatever your desired FOV value is.
Delta Time: Delta Time from Tick or Get World Delta Seconds
Interp Time: how fast you want it to go from current to target.

So long as your "Get Current FOV" is returning the last set value, then it should work ok.

[graceful rampart]

https://forums.unrealengine.com/t/why-does-possess-move-camera-to-pawn/280233 This is the problem that I am having someone has posted on forum but the issue was not answer yet on forum also

[magic parcel]

okay... so I alreayd have this lol

[dawn gazelle]

No you don't, at least not that I see.

[magic parcel]

this pulls the FOV value from the curentFOV

[dawn gazelle]

You have "Target FOV" going into Current.

You have "Default FOV" going into Target.
I dunno what you have toing into Interp Speed.

World Delta Seconds is fine.

Target FOV would need to change every frame in order for it to work right.

[rugged merlin]

They do list a workaround at the bottom of that. I'm not sure what else to try

[graceful rampart]

I was thinking same 😅

[dawn gazelle]

Is it doing it on tick?

[magic parcel]

no

[dawn gazelle]

Then how is it updating every frame?

[magic parcel]

I thought that was the point of the timeline

[dawn gazelle]

You are setting the FOV of the camera component on the timeline.

That is the only variable you are changing.

You want to get the FOV of the camera and plug that into Current.

Then when the next frame goes, it'll read the new value.

The next frame, new value, etc...

Right now, if you're only setting "Target FOV" once on begin play, then that value doesn't get changed.

[magic parcel]

so you want me to go from tick

[dawn gazelle]

I didn't say that.

[magic parcel]

and from tick, I pull the FOV from the camera

[dawn gazelle]

You want to get the FOV of the camera and plug that into Current on the Interp To

You can do this on the timeline.

[naive herald]

Hello, I want to take the rotation value of Bonn and control it so that it doesn't go beyond a certain angle. What should I do

[magic parcel]

Okay, that shift seems pretty small

[magic parcel]

okay, so how would I go about reversing that?

direction node?

[dawn gazelle]

Not in this case.

Your timeline isn't really controlling the values.

[magic parcel]

cause I need to change it based on the bool value

[dawn gazelle]

Really, if you're going to use a timeline, you're probably better off not using an interp and just have a float track with the start and end value you desire.

Otherwise, it could be outputting a 0 to 1 value and you can use that in a lerp instead.

[magic parcel]

is there a better option? that isnt a timeline

problem with lerps is they are not smooth

finterp to has an ease in and ease out

I guess I could do that with the timeline

[dawn gazelle]

You can control that with your own float track.

Make your curve smooth

Make it output 0 to 1

Lerp between those two values based on the track.

[magic parcel]

so, in theory this should reverse it

lol nope, that went back to being shit lol... damn

[dawn gazelle]

Use one connection from the update to your SetCameraFOV.
Whenever you're setting IsSprinting true have it call an event that calls Play (not from start) on the timeline.
Whenever you're setting IsSprinting false, have it call an event that calls Reverse (not from end)

[magic parcel]

so very close lol

so, the first time I do this, it works

when I press again, it just goes from 90 to 90

reverse was not working at all 😦 So I tried this way. I know its not correct

[lunar sleet]

Use Play From Start

[magic parcel]

Okay, when I use play from start I get no interp. I just go directly to the target value

[frank viper]

Hi if your string of executions / execution line is very, very long, perhaps too long and set to execute during a PreConstruct on a Widget, what would happen? Would the execution get cut off once the widget appears on the screen, or would it just continue to execute? 🙂

[magic parcel]

this is what I am having happen

[dawn gazelle]

Don't use two timelines. A single one needs to handle it otherwise you have two different start and end times.

[magic parcel]

so I have three values I need to play with here

current (whatever the camera is at now) | target (120) | default (90)

[lunar sleet]

I haven’t had that much luck with FInterp. Timeline is usually used with Lerp

[magic parcel]

I will try interp again... but that was instant

so I will try again

[lunar sleet]

Not interp

[magic parcel]

lerp sorry 😛

okay, so that worked

but now I need to go from the 120 to the 90

so.. how do I do that?

because current is now 120

so.. if I reverse it, I get nothing

[magic parcel]

okay, that works for a button press. I can hardcode the values in this case

[dawn gazelle]

The "A" and "B" of the lerp, just need to be the default value and the target.

default into A, target into B.

okay, well now that is working!!!

Thank you both for the patience and working with me! ❤️

[dawn gazelle]

Finterp just works with delta seconds and the speed and the current and target to reach the output of this frame for those values.
So like... You're running at 60FPS, your delta time should be about 0.016.
If you had a current value of 0 and a target value of 1 with an interp speed of 1 , that's an indication that you want to move to the value 1 in 1 second, but you're starting at 0.
The last frame took 0.016 (according to your delta time) so the next frame would need to be (target(1) - current(0)) * interpspeed * delta seconds + current = 0.016 as output.
So long as you store that output and feed it back into the current value, the next one would be (target(1) - current(0.016)) * interpspeed * delta seconds + current = about 0.032
next frame... (1 - 0.032 * 1 * 0.016) + 0.032 = 0.048
etc.. all the way until you reach 1. So long as the current value gets updated each frame, then the math of the finterpto can do its job.

[magic parcel]

I bow to your knowledge and helpfulness!

I think if I wanted to make the camera aligned with velocity, finterp would probably be the better option

right?

[ionic cypress]

How you are going to align your camera?

[magic parcel]

you asking me?

[ionic cypress]

Yeah, sorry didn't reply your post.

[magic parcel]

all good, what do you mean by align?

this is what it looks llike normally

[ionic cypress]

You said you are going to align the camera with velocity?

[magic parcel]

with the FOV shift, this iw aht I got

[magic parcel]

I meant... the idea would be, the faster I am going the higher the FOV value

the slower I am going the more normal the FOV is

[ionic cypress]

Ah, ok. Yeah, you can use finterp for the FOV interpolation.

[magic parcel]

this gives a sense of speed and helps to sell the idea of sprinting. With a PostProcess effect this will make it even better

[ionic cypress]

Or, you can make another camera mode like sprinting, then you can switch between two camera mode.

Then interpolating everything between them.

[magic parcel]

yeah, we have a camera plugin that we did that with. The problem is that its not update for 5.4.1 yet

[ionic cypress]

It is more common way if you have different ones.

[magic parcel]

we have been busy with making switch triggers for the dungeon, and the boss AI

I just wanted to hack something in before the coder wakes up! 🙂

[ionic cypress]

Ok, then it is enough.

[craggy lake]

Is there a way to grab the speed of an actor that's being animated with control rig? Or at least a component of it. Calculate component velocity of course returns zero, and the other also returns zero I guess because control rig is what is technically moving.

Is there a way I could compare the actor position from the PREVIOUS tick? I tried the position history one and it also didn't work.

[frosty heron]

Because posses will make your controller posses the pawn which will use the current active camera.

What do you actually want to do?

[frosty heron]

You can cache your previous velocity. That way you can get the velocity of previous frame.

Don't know about control rig tho. I only use it for foot ik

[visual crest]

can some one explain to me why this is happening and how to fix it? basically the float out of my function has data put into the out pin but there is no data coming out of the function. The strange thing is I have another BP of this thing in the world and it works perfectly...

[craggy lake]

But I can't get the velocity of any frame. That's the problem. So I'm thinking manually use get position and somehow store that

[frosty heron]

Yes u can?

You can get your previous velocity

Event tick , get OldVelocity. Print old velocity. Get current velocity (velocity this frame) set old velocity = current velocity

Every tick, your old velocity is the previous frame velocity

[craggy lake]

But I am saying all these velocity things return zero. Since I think control rig doesn't have velocity. And anything being controlled by it is relative to its parent (the controller) so it's all zero. So no I can't.

So ok yes I could have a variable called old velocity but it would he zero

So I think I need to do it somehow using the actor or a bone position. But I don't know how to store it

[faint pasture]

What blueprint is trying to do this? Can you not make variables?

[craggy lake]

Yes I can make variables but I need to get the velocity of a joint and it only returns zero, my assumption is because it's being controlled by control rig so doesn't 'know' it's moving. So that's why I'm thinking to do it with world position

[frosty heron]

Pass it from anim bp?

If you need example look at how the default tps template pass bool to control rig

[craggy lake]

This is being animated by hand as a regular control rig

[frosty heron]

Not sure the connection between getting the last position of a bone with animating by hand via control rig

[craggy lake]

No connection, but it's not coming through an anim bp

I think best way is getting the joint world location, storing it and then getting it again and comparing it to the new one but I don't know how to store it tbh

Calculate velocity from position history! Get socket location! I think I did it

Only thing is I wonder if I can store the history from the sequencer rather than ticks or live update

[barren tangle]

Hello, I have attached my camera to my player controller like that

in another blueprint when i get the player controller. how can i retrieve the attached camera?

[frosty heron]

You are not attaching any camera tho

You are setting the new target to the camera

Nothing to do with attachment here

[barren tangle]

yes

so i need to manually find my bp camera ?

[frosty heron]

What are you trying to do? I never have to reach for the camera like that.

[faint pasture]

Prolly get player camera manager and go from there.

[frosty heron]

Ye prob get player camera manager get camera. I'm not sure tho

U can always do a test

[barren tangle]

i'm trying to create a parallax effect. and i need for that to find the camera position

ok thanks i will try the camera manager

yes it's working thanks

[maiden wadi]

In a 2D sidescroller or something? You shouldn't be doing this on the gamethread if so. Should be in your shaders.

[barren tangle]

it's a 3D game. i just want to put a background just for that. I know it will not be performant but let see the limitation of that approach. If it's not good enough I will try other way

[maiden wadi]

It's more about the simplicity. Moving a UV by the camera position is easy in a shader and "almost" free.

[barren tangle]

because you understand UV... that's a part the game that is difficult to learn and doesn't seems logic to me, without a good documentation or tutorial. People doesn't really explain how to manipulate and understand those UV 😄

but after test the movement of the backgorund is not smooth so i guess i will have to find how to do your approach

[maiden wadi]

What are you trying to parallax exactly? Context matters quite a bit.

[barren tangle]

i would like to have several layer of backgorund. And make them move on different speed base on the "distance" from the camera.
To give the illusion of depth on those flat images.

[lunar sleet]

https://tenor.com/view/peter-sarsgaard-hector-hammond-green-lantern-villain-evil-laugh-gif-15739953

So like a sidescroller? Same Idea but in a 3D game?

If yes. Are the backgrounds 2D or 3D?

[hallow tundra]

How do I send a text from an array in a blueprint to appear in a widget, I have this in the blueprint but dont know how to get it in the widget.

[faint pasture]

[faint pasture]

I mean what class

[hallow tundra]

ineed it to be in a textbox in a widget blueprint

if thats what u mean

[faint pasture]

How is the widget spawned?

[hallow tundra]

I havent made that part yet

[faint pasture]

Whatever responding the widget should tell it what to say or tell it what object it should look at to get what to say.

Then the widget can set its own text

[barren tangle]

yes, but 2D images

i would like to make a simple backgorund like that with different layer of images

the blueprint approach sounds good but CPU is not enough good for that

[maiden wadi]

Which direction is your track? X or Y?

[barren tangle]

X -->

only X

there is no Y movement

[drowsy steppe]

hey guys, i have a variable in a parent actor that i want to set in a child actor from another actor. but when i set the variable of the child in the other actor i cannot access the variables in it. how can i do that?

[maiden wadi]

@barren tangle So UVs are fairly simple. They simply map a 0 to 1 value. 1 to 2 is the same as 0 to 1. 32 to 33 is the same as 0 to 1. If you scale your UVs to use 0 to 2, you'll zoom out and tile once. If you add to your UVs, you'll pan them.

Thankfully there are some easy shader nodes to help with it so you don't have to do everything manually. Panner is one of them that'll help you here. In Image1 if you put Time into a panner's time value it'll just constantly pan the image sideways which gets you close to what you want.

In Image2 we're taking the camera's world X location and feeding it to the panner's time. So when your camera moves long the X axis, this image will pan.

You'll likely need to invert it, and slow it down significantly. But if you do something like this, the background will 'just work'.

[barren tangle]

but UVs means all pixel of the image? the screen? because. most of the time is an input node. So does it mean we manipulate all pixel of the image? and we try to apply the value that we receive in input? and that value is between 0 and 1 ?

[reef portal]

you need to make sure that your variable is accessable, to do that click the check box for "Instance Editable", if you want to have control over the variable when you spawn in the BP then you need to have "Expose on Spawn" checked as well. That should make your variable accessible to other scripts/BP in your game/project. Hope that helps.

[drowsy steppe]

Thank you so much. I did that (of course i had to do that) but it is not working

Maybe because i set the variable where i get the child just as a generic actor?

[reef portal]

ahh, I think I know what you mean now. Why is it not appearing in your variable list, it wont. Just right click on the BP page and type in the variable name, it should appear in the list.

[maiden wadi]

Not specifically all pixels. UVs are just coordinates. If you put a 1024px texture on the same thing as a 128px texture. Most of the pixels might be the same color due to UV mapping. The 128 scales up or the 1024 scales down and they "relatively" match. One just has more definition so less blurry when close. If zoomed out far enough they look the same.

The reason being is that at 0.5x 0y UV, you're roughly around 64 on the 128px size, and 512 on the 1024px size. It just makes textures relative mostly. And learning to manipulate them lets you move textures around or scale them, without having to do it with other costly means.

[drowsy steppe]

No i know that i have to write, but it wasn't appearing even when writing. Not i'm changing the variable types, i think that's where the error is

[barren tangle]

in your other actor, how do you find the Child Actor?

are you sure you have the child actor? can you acess to its function for example?

[barren tangle]

i will try to put some different value and see how it react to try to understand it

[drowsy steppe]

with a get all actors of class and then getting a random one, but i set the array variable to a generic "actor" now i set it as the parent actor, and i can access it directly

i didn't resolve my problem but at least i got to being able to set the variable. I suspected that before, casting to the parent actor referencin that to the child set in the array before, and setting the variable from there, i was setting the variable for the parent and not the child. Could that be?

[midnight kiln]

Uh... In what world is 3250 / 125 = 0?

[barren tangle]

if you use a generic actor you have to cast it to the target actor. generic actor doesn't know the type of the parent actor

[midnight kiln]

Ah, exec pin that used it wasn't executed yet so it hadn't run

[dusky cobalt]

Kinda stupid question, but why there is not all variables in the Get Class Defaults? There is exception for widgets?

[inner anvil]

Hi, I'm currently working on physics hands for VR. I do this with MotionControllerComponent and Physicshandle who grabs a separate actor of a physics hand.
The problem is, because of the way i manage the character, the MotionControllers are inside a SceneComponent which updates on Tick to be in front of the player. but because of it (i think), the PhysicsHandle does not follow the right location. I think it's following the location relative to the parent SceneComponent instead of the Controller world location, but I'm not sure... I tried to change the world to the relative and back, but it was never a right location... Can anyone help?

In the video, the white cube is the Physics Hand and cube with the grid is the Motioncontroller.
The HandPositionFix function runs in the tick and changes the HandOrigin (the parent component of the MotionControlers)

[lusty shard]

hi! I am trying to create a tooltip widget and make a custom button that will always reference that same tooltip widget. How do I get the Tooltip widget variable that I have created and stored in the HUD from inside of my button?

I can get it with context sensitivity turned off for some reason

But I dont know why.

[dusky cobalt]

First thing, there is no way you will need any casts if you are trying to do something like that.

[lusty shard]

I hoped not, but how? I could get the variable without this.

[dusky cobalt]

What is your content of the tooltip? Like what it's based on?

[lusty shard]

it sbase don the buttons details.

[dusky cobalt]

Ok, where are your buttons?

[lusty shard]

so button already has tooltip information already, just trying to pass that to the tooltip widget

[dusky cobalt]

You need to create widget tooltip inside buttons.

So like, create ''base widget tooltip'' with all variables that are coming from Button Reference or what ever.

and then inside button, you create widget base widget tooltip, and pass reference of the button.

and the tooltip with get populated with all the informations from the buttons.

[lusty shard]

buttons are everywhere. Main Menu, pause menu, credits screen etc... theres a build menu in the game which will use a different tooltip widget if i can get this working for the menus.

[dusky cobalt]

It should not be a problem, unless your whole structure is bad

then you have to think about fundamentals

I can show you my example

I was just working on tooltip too

Like, if you have a lot of buttons, and you made them all separately without any like ''base'', then you have problem.

because you have to also manually now create widget inside each of the button

[lusty shard]

so I shouldnt create the tooltip in the HUD then?... because then id be creating this tooltip widget for all buttons that exist.

[dusky cobalt]

Example: I have BP_Unit parent class, that then has like 20 units, doesn't matter

because I create it all in Parent class once

I send there Reference of the unit to the Widget

and then it's all populated in the Widget

[faint pasture]

Tooltip can be handled by an interface if it makes sense

[dusky cobalt]

Does my example clear this question or you still not understand? 😛

so I can show you my next step

because here it get's complicated a little haha

[lusty shard]

so when the tooltip widget is created, it always gets struct info, in my case button info.

[dusky cobalt]

Yes

[lusty shard]

but seems bad to create widget for each button?

[dusky cobalt]

What are you trying to do? I think there might be tooltip built in for the buttons already?

[faint pasture]

Button should just hold the struct. One tooltip widget, which can have its contents filled from some struct

[dusky cobalt]

Or are you trying to make a nice tooltip with a lot of info?

[faint pasture]

Yeah there already is a bit of tool tip mechanics built in. What should your tooltips look like?

[lusty shard]

yea trying to upgrade from built in option

[dusky cobalt]

My tooltip is a little bit more than just text when I hover over something.

[lusty shard]

Then in game tooltip build menu will have this with added costs for buildings.

[faint pasture]

So either have anything you'd need to show a tooltip for inherit from some base class, or have them implement TooltipInterface so they can be queried for the tooltip data

[dusky cobalt]

It's kinda like button should not give a shit about what it is in your widget kinda.

Button is just for clicking.

[faint pasture]

You really need to wrap your head around the data driven way to do this kind of stuff if you want to make something like an RTS.

[dusky cobalt]

The tooltip info should be created in the building / unit / resource / character / anything.

I showed you how to create base widget that get's populated with the info of the unit.

so now how I use it

I have another Widget, which is actually a button. It's also created only once, and is taking info from any other unit (so if I have 20 units, doesn't matter, I have one Widget ProduceUnit, and it's beeing feed with the data of each unit, what ever is needed). And since I feed there Unit Reference at the start, I can also access the Widget Tooltip that I created inside that Unit (can be building, resource anything).

and then I have UI Interface that I send to PlayerController (or HUD if you want).

I send that Tooltip Widget info to the PlayerController

and the playercontroller get's that Widget and adds it as a child to the Main UI > Tooltip Box

it's really intuitive once you understand it

[bright flint]

i honestly like this blueprints/node style
what is it?

[dusky cobalt]

Flat Nodes are free, and then there is Electronic nodes for 10$

both are plugins from marketplace

[bright flint]

and my ue5 storepage just went japaense in the en-us region????

nani?!

[dusky cobalt]

yes, this one xD

[frosty heron]

Why do you need to refer to the instance?

probably just get the CDO to get the info

[dusky cobalt]

cdo?

[frosty heron]

class default object

[dusky cobalt]

I cannot get Unit Reference or the Widget from Class Defaults, I was even asking for it 1h ago here

[frosty heron]

well that's what im saying. Depending on what you are doing, you don't need an instance to reffer to. If you are just reading static data, you can just get the default class object from the class

[dusky cobalt]

I don't understand

I only have class reference at first and I cannot get Widget as variable from class defaults, so that is why I get Actor of that class in this case

[frosty heron]

Nvm, I already see you are doing it

[dusky cobalt]

Yeah, some things I could getfrom class defaults, but I had problem with the Widget that is in that class. I was asking if it's normal or what i'm missing 😄

but I just got actor of class and made work around

[frosty heron]

not sure why Unit reference is necessary here at all

Hmm this is 2D?

[dusky cobalt]

In this case it kind of is, I'm using it here later

and Im not decided yet

if I will get just Unit Reference here and then Get Unit Widget Tooltip

and send just the Widget

or I send Unit Reference and get Widget from that Reference in the playercontroller

not sure which will suit me more, so left two inputs 😛

[waxen sorrel]

someone remember how you add "debug keys" editor only on the character controller ?

[frosty heron]

Im not sure why the Widget is the one showing the UI to the player tho.
What kind of game are you making? If you are just trying to do a mouse over, maybe you can call it from your player controller or else where and just call interface to the widget

[frosty heron]

I feel like it';s not widget job to set reference to what the player interact with

well anyway, hard to make suggestion from my end. Just hope you work out what ever you are doing.

[dusky cobalt]

It's just complicated because there is widget first of the thing that you can produce like Unit Produce

like first I have W_ProduceUnit right xD

and inside that I put that Unit Tooltip

so when you hover on Produce Unit yo uget UnitTooltip showed

and I might want to use that UnitToolBox in the MainUi for other things later, not sure yet

This is best approach I came with myself and it kinda works for me and I think it's scalable

[waxen sorrel]

#blueprint message nevermind seems like UE5 only feature

[random pulsar]

in bp there is a play sound 2d node,but how do i mute the sound?
by volume i know how
is there another way?

[frosty heron]

What's the point of playing a sound if you are going to mute it?

[limber parcel]

u can put fingers in your ears and pretend u cant hear it

[frosty heron]

also Play 2D is fire and forget node, if you need to get a reference to it, use Audio Component

[random pulsar]

i have a ui with 2 buttons, on and off
those buttons mute and play bg music

[frosty heron]

what about it, are you not using Sound Classes?

[bright hamlet]

How you gonna play? 🦶😂🤣

[random pulsar]

no,i just created a cue variable in game instance and 2 functions,then in widget i cast to the game instance and get the functions

i know this is not right

[frosty heron]

yes, it is not right.

Use sound Classes, you can set the volume and other settings based on classes

[random pulsar]

it breakes a lot of opp rules

[frosty heron]

EG. UI, SFX, Dialogue, BGM, etc

well got nothing to do with OOP imo.

[limber parcel]

sound cues exist

[frosty heron]

specifically talking about this one tho
https://docs.unrealengine.com/4.27/en-US/WorkingWithAudio/SoundClasses/

[frosty heron]

@random pulsar check the link above.

You suppose to group your sounds based on it's class (SFX, UI, Game, BGM, and so on)

that way you can just call a node to collectively set the setting for a specific class.

[hidden cape]

Im having a real hard time getting rid of these warnings. Ive remade the enums, replaced references fixed the bp's etc etc. 12 hours of messimg around. Theres no duplicates...its driving me insane. The new project I migrate to works...its in the output log of rhe project being migrated from...does it even matter? Readt to lose it...any help is greatly appreciated.

[random pulsar]

Thanks Cold

[steady night]

is it possible to remove a Enumerator Selecting ingame ?

[steady night]

like if i have a Enum with 5 options can i remove 1 option ingame ?

[frosty heron]

@random pulsar After you set the sound classes, this is how I set the setting

your button can easily just set the volume of the game to 0 and the BGM to 1

[random pulsar]

ohh nice,i also found an issue that your setup might solve,the off button didnt turn the music off

[frosty heron]

well its not like your BG music variable ever been set. You must have get Accesses none error.
Play Sound 2D is fire and forget, it does not return any Object you can refer to.

[random pulsar]

and there is one more ,when i press the on button multiple times ,there is played the same music a lot of times
how do i solve this one also?

with a boolean ckeck?

[frosty heron]

you are using Play Sound 2D, it is your source of problem

unable to reference to it, there's nothing you can do to stop it or changing it's setting as it is unreachable.

Use Audio Component

Button Pressed -> Audio Component Stop Sound -> Play Sound

[random pulsar]

ok ok

thx

[frozen cairn]

How do you do a folding sword animation? for example sword is divided into 3 parts and its unfolding one part after another.

one way is to animate a static mesh rotation and another way is to do skeletal animation

which way do you prefer?

[frosty heron]

deff skeletal mesh and do everything in your 3D program

[dreamy mountain]

im tryna set a scoreboard up, but i cant change the visibility of the board, idk how to fix it
https://i.vgy.me/J1b2Hq.png
https://i.vgy.me/ULTxx8.png

it just doesnt change it from hidden to visible

[rose crest]

try to add it to viewport and remove, dont change visibility

[dusky cobalt]

Okay... I just realized that if I won't have Actor of Class in the level, this is not gonna work.

What are other ways to get variable from the class?

or I will just have to use cast?

I know I could put actors somewhere far in the level and it would work, but just curious about most straight approach?

[faint pasture]

Why do you need a reference to a spawned unit there?

[dusky cobalt]

This is a Widget of a Produce Unit Button. I create these from Building (Building holds data, which units it can produce, and the array is of Classes of units).
So in this button I only have Unit Class Reference.

Then this same blueprint, I have logic that on hover/unhover I send info to PlayerController to show Tooltip of the Unit in the UI.

BP_Building

[faint pasture]

You should be able to pull that off of the class defaults. Why would you need an instance of the class?

[dusky cobalt]

I need to get Widget_Unit Tooltip from Unit Reference Class or Unit Reference

Any idea why it's not showing here?

It's in the class, maybe I need to set it to User Widget?

[faint pasture]

The class for a unit shouldn't hold a whole widget. It should just hold the data required to construct that widget.

We should probably already has. What does the tool tip for A produce unit button show? Presumably a description, some of the unit stats, other stuff, right?

[dusky cobalt]

Oh, should I create it just somewhere else? like inside Button Unit?

Yeah

like it works, but only for the units that are in the level

like I have other buildings with other units, and if they werent spawned, then I dont see them because Actor Of Class doesn't work.

Okay, if I understand right. I just have to create that widget

in here

instead of Getting Actor of Class

[faint pasture]

You shouldn't be getting actors of any class for any of this.

[dusky cobalt]

Yeah, hmm

[faint pasture]

From the building, you should be able to figure out which units the building can create. Given a unit class, you should be able to figure out all the info needed to fill out a tool tip for the create unit button. You don't need to have a created unit to do that.

[dusky cobalt]

Like that?

I will expose other things for that widget, this is example of 1 detail.

and then I will just send that widget further

[faint pasture]

Yup

[dusky cobalt]

That's even better

lol, thank you!

really my mind was kinda blown because not everything was working and couldnt find reasons, then I found out it's beacause these actors must be loaded in the level, which is not always good

[mint blade]

hello guys, i need a little help, want to reduce the sound timing of my footsteps when in crouch mode, because it hear as if it was walking normally, it's a FPS game and right now i have no animations in the game, these are the blueprints, i hope some one can help me, thanks.

<iframe src="https://blueprintue.com/render/n4qx3svf/" scrolling="no" allowfullscreen></iframe>

[remote meteor]

you could artificially slow down the footsteptimeline, by adjusting playrate, based on movementspeed i suppose

[mint blade]

well, that will works, i already set the "stop sound effect" when speed is 0

im new with the engine and im trying to add a second parameter, "when walk speed is 300 (crouch mode), play the footsteps more slowly".

my footsteps are at 0.45 each time in the timelime

and when im in crouch more i want it to be at...0.80 more or less.

then, when i get up again, go back to 0.45

[tawdry basalt]

just check your walk speed and then change the footstep sound speed

[proven crown]

After I open the new level AI stops working properly(AI Move to). If I set navmesh from static to dynamic in project settings, it works inconsistently, and can follow player just to suddenly abort. Also, after I open new level, and press Alt+S, it no longer shows navmesh.

If I start level with ai directly, AI works perfectly. AI is spawned on the level after some time

[mint blade]

the walkspeed is ok, i want to slow down the footsteps from my timeline when in crouch more.

[tawdry basalt]

why do you use timeline? Can't you just change it with Set node?

[mint blade]

i have no idea how to do that, i used a time line because the course im doing right now 🙂

[proven crown]

here is Enemy Ai class

[lofty rapids]

what does that look like ?

[mint blade]

hey, here are the blueprints i used:

<iframe src="https://blueprintue.com/render/sujzuocw/" scrolling="no" allowfullscreen></iframe>

<iframe src="https://blueprintue.com/render/kbj4hqcs/" scrolling="no" allowfullscreen></iframe>

<iframe src="https://blueprintue.com/render/n4qx3svf/" scrolling="no" allowfullscreen></iframe>

[lofty rapids]

i dont see footsteps timeline

[tawdry basalt]

yeah, same

[lofty rapids]

thats probably where you would have to change

[tawdry basalt]

oh wait

it's the last link

[lofty rapids]

oh ok i had to go more right

[grave relic]

I want to make sure my audio is finished playing when I click my PLAY button before starting the scene, which node should I use? How can I do?

[mint blade]

the footsteps CUE works just fine when walking

now i need to slow down the footsteps sound and play it when in crouch mode.

[lofty rapids]

i would consider another timeline that you run if your crouching

[mint blade]

i can do that, but how do i tell the engine to play it when in crouch mode?

[mint blade]

i copy the timeline, and modify but how to add that timeline in particular when in crouch mode to play it

thats my problem

[lofty rapids]

you may be able to say if max walk speed = 300 then play the other one

if it's 600 then play the basic walking

or use a boolean for isCrouching

[idle vigil]

im trying to rotate the first card upside down in my blackjack game but it wont rotate in the correct way even though i have tried all three axis. Where is my mistake?

[lofty rapids]

so it's upside down but not facing the right direction ?

[idle vigil]

its like in the resident evil game where the opponent wont see the first card like this

[mint blade]

yes, this is what i want.

you may be able to say if max walk speed = 300 then play the other one
if it's 600 then play the basic walking
or use a boolean for isCrouching

[idle vigil]

like in the picture the card should be flipped with back face facing up but i tried all 3 axis but still wont rotate correctly

[mint blade]

after the croush timeline?

[lofty rapids]

when you play the sound, check if your are crouching and play the other one if so

[mental trellis]

What happens if you lose?

[lofty rapids]

when you check if moving, also check if crouching and play the crouch if so, if not play the normal one

[mint blade]

let me try...

[idle vigil]

goodbye fingers

[mental trellis]

Nice.

[Crossposting this from #cinematics , because it's more of a blueprints problem I suspect.]

Hi guys, I am trying to hide my HUD during LevelSequence playback, using a simple BP function. I know SetVisibility to Collapsed is being called, but it's still visible during playback. Help please.

[gaunt stirrup]

Does anyone know how i can toggle a image visibilty with a button inside a widget

[grave relic]

Guys, I have this PLAY button, currently, for the Menu scene, I have a separate card so "MainMenu", this card contains the base GameMode of Unreal Engine "GameMode".
I have a completely custom GameMode with the game UI and everything, I want when I click the PLAY button it loads my GameMode "BPI_GameMode_MP".
How can I do?

[dusky cobalt]

Set the gamemode you want to be after level is opened in the level.

override world settings basically

[tulip karma]

This did the trick, with the Velocity set to either 1000 or -1000 depending on the direction, thanks again 😄

Don't actually need the set initial speed either

[stoic ledge]

Makes sense too?

[tulip karma]

Yeah, it's exactly what I thought I needed deferred spawn to do 🤦‍♂️

[grave relic]

I'm stupid! Yes Thx u!

[tulip karma]

I almost had it like this at one point but I missed exposing the variable on spawn to make the pin appear in Spawn Actor D:

[dreamy mountain]

how would i change what needs to be hit for the event anydamage on an enemy? i want a custom non capsule collision hitbox

im using that yellow one instead of the capsule

[balmy viper]

Even ideas for things to investigate would be good, thanks

[lofty rapids]

maybe on collision call damage actor

and it should trigger

but whats the error ?

[sharp python]

Is there anything bound to visibility?

[balmy viper]

how do you mean bound to?

[sharp python]

If it's not that, put a breakpoint on where it hides it and see if the breakpoint gets hit

[balmy viper]

oh I've never set breakpoints yet, didn't even know you could, in BP

ya learn something every day!

But I know it's being called, from tracewrites

[balmy viper]

is that snippet from the class settings of a widget?

[dreamy mountain]

how do i do that

[dreamy mountain]

tried to delegate to it

just didnt compile after disconnecting it

[lofty rapids]

whenever you damage the actor through a node, that event will be called

so just call it on collision, what are you trying to do ? be able to shoot it in that box ?

[sharp python]

I mean yes

[faint pasture]

Show where your attack or weapon adds damage to the thing it hits

[faint pasture]

just have the capsule not block the projectile and have the other hitbox block it

and voila it'll work

[torpid imp]

hey guys, I have a questions here that I'm not even sure what keywords should I looking for. I have an asset, every time when I press interact key player should move to its location and press again player will back to the original location

I achieved this function, but I also want the player camera can change to the asset's camera

Like this, what blueprint node should I use?

[lunar sleet]

Set view target with blend

[torpid imp]

Yea, I tried this, but I couldn't attach the camera on it

*to the new view target

[lunar sleet]

You’re trying to connect it to blend time there

[lunar sleet]

Show the entire error

[torpid imp]

The mouse moved when I made the screenshot

ok I tried to make it work, now it looks like this

[lunar sleet]

Ok don’t just connect things at random lol

[torpid imp]

ok, do you have suggestions? I just try to make it work by my interpretation

[lunar sleet]

You need a ref to the other cam

That needs to be an actor

[lofty rapids]

destroy after you apply damage

[torpid imp]

wait you mean the camera itself?

[lunar sleet]

Yes

You can also try to feed it that actor if it contains the camera, might work

[torpid imp]

I will try this method, thanks

[random pulsar]

@frosty heron can you tell me please where do you right the logic for audio settings?I write it in game instance

[torpid imp]

Solved it, just need to connect player pawn on it

[random pulsar]

dispatch is gray,i cannot add inputs

any ideas?

[lunar sleet]

It says Read Only. Is it an interface function or something?

[random pulsar]

its a widget and i followed a tutorial,but there is 4th version of unreal

i have 5.3

[lunar sleet]

that should have nothing to do with it

[random pulsar]

https://www.youtube.com/watch?v=tK8ghXHDz10&t=580s

[lunar sleet]

Lol, I've seen that guy's crap before. I'd steer clear

He should rename his channel to CodeLikeMeCauseIGotNoIdeaWhatImDoing

[dusky cobalt]

sadly like 85% of tutorials on yt

xD

[random pulsar]

i dont like him also

[lunar sleet]

ok, where did you get this function from and what type of widget is this slider thing

[random pulsar]

but i dont find other tuts

[lunar sleet]

Is your slider isVariable checkbox checked?

[random pulsar]

its a widget with a slider,i plan this to be the music slider

[random pulsar]

yeah

[lunar sleet]

so why are you using a dispatcher, what are you trying to do with it

[random pulsar]

man,no idea,follow the tutorial

[lunar sleet]

I don't have time to watch crappy tutorials. You don't know what you're trying to achieve?

[random pulsar]

he creates a input variable in dispatcher and connects it withthe slider event

[lunar sleet]

k, no idea why he's doing this, but here, if you want to make that happen

did you bind this dispatcher anywhere?

[random pulsar]

not yet

[lunar sleet]

ok, make a new custom event, give it a float input variable

like this

[random pulsar]

in the widget?

[lunar sleet]

ideally, wherever this dispatcher is supposed to be bound

guessing it's either in the widget or some parent class

but for now you can create it in the widget itself if need be

this is just to show you how signatures work

[random pulsar]

ok

now what

[lunar sleet]

now click on your onValueChanged dispatcher in the left panel

Click Copy signature from and select the MasterVolume event

make sure you've compiled first

[random pulsar]

thx
it worked

[dreamy mountain]

[tulip karma]

Having some trouble with crouching, and not sure on the best way to resolve it, if I don't change the capsule size when crouching the sprite is in the correct position when I crouch, if I reduce the capsule size - which for collision purposes is what I'm after - the sprite clips into the floor, I guess I need to offset the sprite somehow so that the sprite remains in the same position it does with the unchanged capsule?

[faint pasture]

yes

[tulip karma]

Is there an easy-ish way to achieve that? So many different options D:

[faint pasture]

Could just author sprites so the pivot is at the center

[tulip karma]

Ohhh, I forget why they weren't to begin with now tbh, I'll take a look, cheers 🙂

[spark steppe]

[jolly oriole]

I have an actor component that is created and destroyed at runtime, that needs to get a reference to a specific actor in my level. The actor component is added to my player character.

The specific actor will always exist in the level, and only one of them.

What's the best way to handle this?

[maiden wadi]

Just GetActorOfClass it, IMO.

[dawn gazelle]

Nothing wrong with a GetActorOfClass to do this.

[jolly oriole]

Any performance overhead? I'm making a tower defence which will have a bunch of actors

idk if unreal does some pre-filtering magic or if it brute force gets everything

[maiden wadi]

That's not how that works.

[spark steppe]

that's one of the rare cases where get actor of class is fine to use

it's oneshot, so i wouldn't care about 1ms vs 0.4ms

[dawn gazelle]

I believe it uses a hashmap for lookup. If you have tons of actors, then I wouldn't necessarily set a reference to conserve memory usage unless you plan on using it extremely frequently (like on tick).

[jolly oriole]

LOL

[spark steppe]

i think it just iterates over all actors

[maiden wadi]

It does not.

[spark steppe]

oh true

it does prefilter by class

[maiden wadi]

If you create three instances of some classes. One is an Actor. One is a Pawn. One is a Character.

Unreal puts each of these instances in a bucket for every one of it's parent classes. So with these three classes. You have three buckets. Actor, Pawn and Character.

However, Actor has three instances. Pawn has two instances and Character only has one.

This is because Character is a Character, a Pawn and an Actor.
Pawn is a Pawn and an Actor.
And Actor is an Actor.

So when you ask for a Pawn. It goes directly to the Pawn bucket and dumps that list into an array of two to return to you.

[dawn gazelle]

https://tenor.com/view/math-meme-math-is-math-meme-mr-incredible-the-incredibles-the-incredibles2-gif-20591317

[jolly oriole]

Oh cool, so in this case get all actors of class sounds incredibly efficent for my usecase

[maiden wadi]

Largely there's not really any overhead of GetActorOfClass. GetAllActorsOfClass "CAN" be bad if you're returning an array of hundreds, but that's mostly the array allocation more than anything.

[spark steppe]

apparently i mixed it up with GetAllActorsWithInterface

which iterates over all actors

[deep lagoon]

hey
looking for some deeper insight on how to best manage sound for character

eg pairing sounds to discrete behaviors
ex i have a charging enemy that plays a sound for that charge

what are some best practices for managing sounds like that
preserving audio components vs respawning and destroying them?
when should i think about a higher level sound manager component etc?
realized i'[m just defaulting to managing each possible sound in parallel and that feels sub-optimal
--can't really find any resources on this subject

[maiden wadi]

Yeah. Anything that doesn't have a Class input is bad.

[spark steppe]

yea, same for Tags

[maiden wadi]

Are you using GAS?

[deep lagoon]

no

[steady night]

how can i make sure a UMG is not overlapping Other UMGS ?

[jolly oriole]

another widget laying them out

[steady night]

i have this issue wherea a widget is overlapping another widget even if i change the Z order

is there some other settings for that ?

[maiden wadi]

Oof. Well. Normally you'd have something similar to a Cue that GAS uses. This manages your visuals for an ability or effect. Spawns and maintains particles, plays sounds, sets material parameters, etc.

EG if your charge was an ability, you would simply create a cue when starting it and end that cue when it was done. Can also do it by applying a GE too, less manual that way, and probably useful to add more tags and stuff. But either way one way or the other the starting of this ability creates that Cue. This replicates for multiplayer so it also works on clients. And that cue's beginplay or init sets up the visuals/sounds. Like starting to play a charge effect or binding to the character's animBP for footsteps to play a different larger thudding sound. When the ability ends, the cue dies, unbinding things, killing particles and stopping sounds.

Character doesn't have to know about these sounds, particles, or anything. It's all about the cue. So that same character can just be used anywhere regardless of abilities it has and doesn't have to keep a lot of stuff softreffed or loaded.

[tepid hatch]

can anyone help me with debugging what is happening with my blueprint i am trying to make a keypad that when i want i can make the code random and it doesn't seen to want to work properly i am transferring over from unity and don't understand the blueprints too much

i am using horrorengine as a base and it is blueprints which i am not use to

the pics show where i am getting the leads from and the blueprint min is 0 max is 9 if that helps

[dawn gazelle]

Are you just adding the randomly generated values and not multiplying them to match their digit?

[tepid hatch]

should be just adding

[dawn gazelle]

Like here... if it chose 5 2 4 6 for the random numbers, the value would be 17.

But then you're checking the player's input for 5 2 4 6 would be 5246

[spark steppe]

just generate one random number between 0 - 9999 and padfill

also you really want them to test out 10.000 combinations?

[tepid hatch]

thanks i am just not use to blueprints because i copied it from the base on the other

no i will have it around my map just one number at a time just want it randomized though

[frosty heron]

Use array

thx just needed a second pair of eyes

If I switch the tracks manually with Previous and Next functions, all of them play. But autoplay only ever plays every other one.

I'm losing my mind because there's nothing whatsoever that could cause it

I'm having a problem where I have a projectile component with an initial velocity set to 700, but when I actually spawn the actor, it refuses to move no matter what I try

Is there any reason that would be happening?

I need some one who is good with box extent math. I am 90% sure this is right and should work but once I moved my box to a new place the enemies can consistently spawn out side my box even though they should not be able to get within 1000units of it when spawning. https://blueprintue.com/blueprint/hrle1oeq/

white circle and red circle position itself to the enemy actors position in screenspace

but it doesnt quite work

is there some sort of parallel node, or split node, which takes one execution path and outputs two

id rather not have to drag out from the tail end of the previous thread

i guess i can make that a function

[lofty rapids]

a sequence ? @steel star

you can add as many pins as you need

Hey folks, I'm attempted to have props be clickable in my project. I was avle to have them clickable and print a string under the top down game mode - but my process doesn't work in the third person. Any advice?

[steel star]

How do you get the UPlayerInput object for an APlayerController? It has a property for it but its not exposed to blueprints for some reason

[lofty rapids]

did you enable click events in your player controller ?

[olive yarrow]

aaah the 3rd person template didn't include the player controller, i'll port it over from the top down see how that goes

[lofty rapids]

you should be able to just make a blank one

and set it in there

unless you put code in there

then you'll have to copy that over

[olive yarrow]

no code at all, there was some blueprints for movement but i didn't have movement enables any how

[lofty rapids]

just create a blank one, and set it in the override

[tulip anvil]

the third person template definitely contains a player controller.

[lofty rapids]

then you can enable click events

[olive yarrow]

enabled... still nothin'. Maybe i should stop trying to pull these long sessions 'cause it's the easy stuff i'm forgettin' here

[olive yarrow]

that's what i was thinkin'! I knew i wasn't losing my mind, but the content browser refuses to believe it's there

Question:

So I'm making a game where only in one level I'm utilizing a grid object I've made. I want to be able to utilize the information from the grid from outside it, so I have it being defined in the game mode itself so I can point to it when I need to.

If I run this on levels without the grid, it'd cause problems since I'd be trying to set the Grid variable to something that doesn't exist. So, how could I add a check between the Get All Actors of Class and the Set Grid to make sure it actually found something before trying to set it? I think I need to add a branch, but I'm not sure what I would need to set the condition to check for.

[olive yarrow]

ohp, got it!

[tulip anvil]

its not in the content browser, its attached to the character as "character move component"

[olive yarrow]

aaaaah, but then is a seperate blueprint in top down?

[bitter raven]

hello, how to make minimize button from blueprint?

[tulip anvil]

they might have done something different for the top down template, i'm not sure.

[olive yarrow]

fair nuff, but preciate the free knowledge!

[tulip anvil]

i always just use the third person template as my base.

[storm solar]

check if actor exists?

[tulip anvil]

seems to be the most "complete"

[storm solar]

try "is valid ?"

I have an issue where in UE 5 where my ai character will only T pose instead of usning blend space animation. Ive been following leaf branch games RPG series and have been stuck on this for several days. I looked at a fix for this and use acceleration for paths was already checked by default. How can I fix this?
