blueprint

[eternal reef]

Maybe use an enum switch based on category (pages for your UMG) instead of having to loop through all your objects to find the correct tags

[shadow crescent]

can my items still have more than one tag this way?

like with, for example a fence, there are different heights, lengths, materials, etc

[eternal reef]

You "could" include as much information as youd like to, but nesting with structs, enums, etc. is always sketchy in Blueprints

[shadow crescent]

in fairness, this only has to be done once, and updated when unlocking anything new

or would it HAVE to be called each time the build menu is opened?

[eternal reef]

I guess you only need to refresh it then, but by sketchy I refer to the actual development process
Adjusting settings after you made some changes to the variables can lead to bugs (well at least it did for me often enough)

[gentle urchin]

BP structs are horrible

prone to bugs and errors

relatively hard to work with aswell just adds icing to the cake

[shadow crescent]

I do find them inconvenient too, lol

I can't why I can't just have a normal data table, lol

[brazen merlin]

Gameplay tags right?

[shadow crescent]

yeah

like if you search for a type of wood or metal relevant build pieces will show up

[brazen merlin]

Youve got layers is the thing

[gentle urchin]

what stops you with regular datatable?

[shadow crescent]

different major cats

[gentle urchin]

so?

filter the db rows

[shadow crescent]

and on the right will be grouped by tags

[brazen merlin]

Cant edit the values of a data table, but u want that right?

[gentle urchin]

filter the filtered db rows for the tags

[shadow crescent]

I am not sure I will need to edit anything

[gentle urchin]

if you do need to, db is not the road to victory

[shadow crescent]

i'll be tracking whether they have unlocked it in a different table I think

[brazen merlin]

Well if you commit to dt you cant 😋

[shadow crescent]

I have no udea

[gentle urchin]

by different means*, not a table i hope

[shadow crescent]

just brainstorming at the mo, lol

[gentle urchin]

All build data could live inside a db

its static, known,

and has a set of rules for filters

[shadow crescent]

this is what I suspected

[brazen merlin]

Maybe just check out gtags

[shadow crescent]

will do!

[gentle urchin]

you could

have gameplaytags in a container on the player,

[brazen merlin]

In case you decide you need to edit things

[gentle urchin]

which basicly just enables some db row

[eternal reef]

Maybe something like:
Datatable holds all building information (un-editable)
Map Variable holds "currently" possible buildable objects
Other variable holds resources
just a guess

[gentle urchin]

I'd just to tag 😄

[eternal reef]

(Map is not possible for multiplayer btw.)

[gentle urchin]

instead of map

[shadow crescent]

sorry for the noob Q but whats the key different between a data tab;e and map?

oooh, I want MP eventually, lol

[gentle urchin]

a map is a pair of something

[brazen merlin]

A map is basically two columns

[gentle urchin]

a key paired with a value

while a datatable is some variable struct

[shadow crescent]

so as part of the save file, I will simply list the ID for each research?

[gentle urchin]

could do that

but if its an id

you dont need a map

you can just stuff it in a int array

if the id exist, the thing has been researched

[shadow crescent]

quicker to process?

[gentle urchin]

less checks i suppose

[shadow crescent]

I want TONS of items eventually ... maybe even a marketplace, lol

[brazen merlin]

Parallel arrays?

[gentle urchin]

sounds like you're way out of scope

[shadow crescent]

lol

eventually maybe 😛

[gentle urchin]

multiplayer, tons of items ,

[brazen merlin]

Mp use GAS

[gentle urchin]

we're discussing a datatable vs Map 😛

[shadow crescent]

lol

we are discussing

something I have no clue about 😛

[gentle urchin]

Point in case ^^

[shadow crescent]

lol

[brazen merlin]

Good night then

[gentle urchin]

if its just a binary state, then a single array would suffice

[brazen merlin]

Jw if thats what you meant

[gentle urchin]

I'd consider dataTable for the build info, and some gameplaytag on the rows for checking if the player has researched it or not

datatable would also contain an enum for sorting into categories

or

you'd use the gameplay tag as a row lookup

Wasnt there some nice method there for grabbing the bigger categories...

nvm, im mixing the last part there with something else 😄

[shadow crescent]

I'm learnin

kinda

😛

a lot more than I knew before even though still a little lost

when it's time to scale up ... it will be fun finding a solution

[gentle urchin]

something like this

Along with a "category" filter

[shadow crescent]

oooooh, sexy code!

[gentle urchin]

not knowing how you want it, you may or may not want to show stuff that is to be researched

[shadow crescent]

lol

a few nots in there!

[gentle urchin]

maybe they are grey, unclickable, or maybe they dont exist

😄

[shadow crescent]

not kidding ... a little harder to digest, lol

[eternal reef]

Just do yourself a favour and really think what you need / want
Such systems can easily cost you a lot of time by having to rework them 10 times

[shadow crescent]

indeed

[shadow crescent]

bookmarked

[gentle urchin]

Using tag container should give you some flex imo

but surely, its not perfect

[shadow crescent]

easiest way to book mark discord chats, lol

[gentle urchin]

this was a tad more complete

didnt care to create a new struct just to show an example , so you gotta live with my transportrequest 😛

[shadow crescent]

lol

Has Tag

thats related to the tag mechanic rather than Tag exisiting in the dataset?

[gentle urchin]

its related to gameplaytags

[shadow crescent]

right

look at me learn! lol

[gentle urchin]

So the Category is a single tag,

updated when a ui button is presed

[shadow crescent]

thank you Mr Squizel

[gentle urchin]

while Research Tags is a tag container

which can hold many many tags

[shadow crescent]

nice

[gentle urchin]

another nice thing about these is that they are way easier to keep track off imo

since they can be grouped and separated and listed like this

[shadow crescent]

nice!

[gentle urchin]

instead of some manual input type

I'm still experimenting with them so this setup could be completely flawed , but i have yet to experience why 😄

[shadow crescent]

loooooooooooool

[bitter helm]

How can i make these variables as an array in my struct?

As I have multiple materials

[maiden wadi]

Click the little O icon and change it to the array one.

[bitter helm]

Damn

It was so easy

💀

[shadow crescent]

🙂

[bitter helm]

Thanks!

[shadow crescent]

nice neat box BTW lol

[bitter helm]

lol thanks

[shadow crescent]

better than I would have done

[trim matrix]

hi guys

virtual default joystick is not appearing in my gamemode(GameMode_1) but its appearing in another gamemodes(GameMode_2)

whats the reason will be?

[orchid star]

try checking they have the same playercontroller class

controls are stored in playercontroller, not GM

[halcyon grove]

morning, is there any issue that can be caused from calling a macro from within a function?

[crisp lance]

In CPP I often "pass by reference" to avoid copying structures on the stack. The goal is memory efficiency.
Should I apply this logic to Blueprint too or is "pass by reference" just in case you want to modify the input?

[halcyon grove]

specifically, I'm using interface to call damage calculation... but within "damage calculation" there can be instances of "damage over time"

which I think would need to run via a function

i mean a macro sorry

because of the timer aspect of that

[orchid star]

Use timers

[halcyon grove]

yes i know that bit

[orchid star]

I am not sure of the answer to your question but if you are using macro guessing you use delays

[halcyon grove]

xD

[orchid star]

use timers

[halcyon grove]

like because you can't use timers within a macro

[orchid star]

get used to them

[halcyon grove]

i mean a function

[orchid star]

you can

[halcyon grove]

sorry its early

[orchid star]

timer is not delay

set timer by event etc

[halcyon grove]

ok and if I use a function to call that within a macro

the timer will still work as intended?

i know I can just write this and test it out etc etc but just wanted to ask before I put in the work

[orchid star]

this keeps looping

[halcyon grove]

ok great

[orchid star]

you can stop it after storing it to a timerhandle

then invalidate it later on

[halcyon grove]

I think thats what I was worried about

[orchid star]

you can also choose to not loop etc

[halcyon grove]

i thought that functions had "timing" issues but they can still run timers its just delays

they cant call

[orchid star]

delays are not good

you cannot control them for first of all

[halcyon grove]

hmmm

well actually

while we're on that subject

what I have done

is set an attack speed value

by using a delay

and after the delay it turns on a boolean

[trim matrix]

ya they have the same player controller class

[halcyon grove]

1 sec I'll show you the code

[orchid star]

just avoid delays its not a good practice

it can work for you sure

[gentle urchin]

timer like this makes alot of sense for dots imo

[orchid star]

it doesnt make it a good choice though

[gentle urchin]

cycle an array of current dot's -> subtract from remaining time -> apply damage each tick interval

[halcyon grove]

I did this to control the attack speed

[gentle urchin]

attackspeed of 2 would mean -1 delay

[unique falcon]

Hello everyone i have a problem with spawning the default pawn, all i did was i changed the static mesh which resulted the mesh to be a little lower as shown in first and second image and now it doesnt spawn, tho i can easily posses the same BP which is in the level with no problem.
I also get this error "Accessed None trying to read property CallFunc_K2_GetPawn_ReturnValue" i think its because the pawn didnt spawn.
When i change the mesh to the default one its spawns with no problem
any help will be appreciated.

[orchid star]

If I spam attack

and not hold it down

You will not be able to fire again with this I think

not sure tho

[halcyon grove]

no it works perfectly

to explain a bit here

[orchid star]

then what is the problem

go with it

I said what I said

[halcyon grove]

yea it was just planning for the damage application part of it

no worries 🙂

thank you

[eternal reef]

Might be worth trying to quickly disable the collision to check whether this is causing issues

[unique falcon]

Yeah its actually the collision now it spawns

i dont know why thats the problem?any better way to fix it?i have no idea what its colliding with

[eternal reef]

Id first try to just spawn it in a clear area with just a floor (and move the spawn further up from the ground)

[unique falcon]

wait i think its the pawn when i ignored it it now spawns lol how is that possible

[eternal reef]

As you have two different meshes they collided with themselves

[unique falcon]

i have my playerstart waay up

alright thank you so much you saved me hours

[bitter helm]

Can someone plz tell me how I can save my character?

[eternal reef]

What do you mean by save your character

[bitter helm]

I have a modular character

With different parts like hands, torso, pants, etc

All having multiple materials

I want to save my character with a press of a button

So that the same character can be used in any level

In short how to save my character after customisation

[eternal reef]

Id go for a GameInstance

Save the selected stuff in there and retrieve it when necessary

[bitter helm]

Yes I did

I also created a structure

To save the modular parts and the materials

But idk how to make it work

[eternal reef]

You could for example
On Begin Play call the gameinstance and retrieve the information and set it on your character

[topaz badger]

Saw somewhere that mentioned blueprint nativization running 10x faster, which makes sense but I could only find info from 3 years ago from when this was introduced. Is it still best practice to nativize heavily used blueprints (Like player characters)?

oh wow ok thanks, so I shouldnt at all worry about it?

haha gotcha, thanks for saving me headaches :)

[bitter helm]

Here is the system

Ive wasted 6 hrs on this

[cunning bane]

Hey!
Any tip how to access cpp inherited field/methods from a blueprint (base class -> child actor -> blueprint)?
Currently, I use child actor class as a proxy to expose base methods. Do we have any other way?

[bitter helm]

This is my widget bp

I want to save my modular character with all the materials in the *CharGameInstance

[eternal reef]

Is it possible that the materials can be changed? Otherwise set it directly on the mesh so you dont need to save them

[bitter helm]

Yes I need to change the materials

Im working on character customisation

[light token]

Hello. I'm very new to profiling and just ran some traces after optimizing some things and now I'm trying to interpret the results and I'm a bit shocked. The bottom picture is before and the top picture is after. If you look at the Incl tab to the right it says the old results did 1.3s over something (a tick or something else?) and now it does 85ms. Does this say that I improved performance? I do notice a 10FPS framerate raise in the editor. But I'm new to this so I might need some help on this.

The change I made was a stationary light set to static and substepping from 2 to 1

[eternal reef]

@bitter helm somethings off with your character reference in GOK_Base

[bitter helm]

Hmm

[eternal reef]

I mean you call a function within GOK_Base is there even a need to plug the char ref in

[bitter helm]

No lol

I did that now

I didnt make references to game instance and character properly

@eternal reef it still doesn’t work

Its not giving any errors

[eternal reef]

You need to be more specific, what exactly does not work
I mean did you manage to save all settings correclty?

[bitter helm]

Yes

Its not giving any errors now so I think yes

[bitter helm]

Is this enough to carry the changes made to another level?

Or do i need to load the changes somehow

[eternal reef]

Okay for your understanding
Basically what happens
The Character which you set up with your customization is not the same when you transition levels anymore as a "new copy" is created
Therefor you have saved the settings of your first character, but you need to apply them to your "new copy"

[bitter helm]

Ok

[eternal reef]

So you need to set up the logic that on spawn of your character it checks what you have picked in the customization
Basically what you can do is in your character:
Event Begin Play -> Get Gameinstance -> Get Settings -> Apply on character

[bitter helm]

How can I do that?

[eternal reef]

Event Begin Play -> (Get GameInstance) -> Cast To GameInstance (Or Interface) -> Get Saved Parts -> Set Skeletal Mesh / Mateirals of all your different slots

[bitter helm]

Hmm

[eternal reef]

And you might need to consider as when first loading up the character there is nothing set in the game instance
Therefor you might need to set default objects into the Saved Parts Object

[bitter helm]

Ok let me try

[light token]

I did make a package build but I did a development shipping configuration because otherwise the insight tools don't work.

[lime cairn]

I've got a Vive Tracker controller that I want to use as a camera. Due to design constraints, I can't position the tracker like the image attached, but rotated 90 degrees so that the X axis is facing upwards and the Y axis is facing backwards. How do I implement this offset? I tried adding 90 degrees to the Orientation but it's still showing some funky behaviour.

Is this a case where simply adding or subtracting an offset won't work? Or I just haven't stumbled on the right amounts

[bitter helm]

@eternal reef IT WORKED 😭😭😭😭😭😭!!!

Thank you so much

[light token]

Wow, I tested it again with substepping 1 vs substepping 2 and it improved by 1/3!

[bitter helm]

But how do I set default mesh?

[eternal reef]

No problem, good to hear
Just click on the save variable in the gameinstance in there you see the free slots

[bitter helm]

Done

👍👍👍👍

[bright frigate]

hey, is there a way to enable or disable a material slot?

E.g. you can hide a component of a blueprint with a boolean and a set visibility node in the constructor.

But how about materials? I've realised that in my door blueprints, there are some doors that take two materials and the others only take one. This is the source of those map check errors talking about overriding 2 materials to 1 slot.

Ok I figured it out. Branch node to the rescue lol.

[bitter helm]

How can I use this animated button as it only has the “on visibility changed” and its s widget bp

[safe iron]

Hey there, wanted to share a thing, not sure if I did it right, but I am still proud of it

[random crow]

I think that if it is a custom widget, you need to expose o create the proper custom events

[safe iron]

I needed a subsystem to calculate health inside of different Character classes, but since I am an ignorant in C++ I couldn't make one... But turns out I am no normal person either so I coded a Macro in Blueprints instead and I'll use it as if it was a subsystem

[trim matrix]

simple question, hopping someone could help me with it:

when i call "Spawn Actor" node with an actor, does "Spawn Actor" calls the actor's constructor in parallel execution order? like if i have a lot of code inside of the class constructor, when i spawn the class with "Spawn Actor" node, will the node wait for the constructor to finish constructing the object before executing the code after it? or will it just do it in parallel? (sorry i'm kind of new to UE and programming in general and idk the technical term for parallel execution)

[safe iron]

If I get it right, you have a lot of code connected to the input of Spawn actor, right?
If so, It will wait to all the code before it to be executed, from left to right, if you want your node to be executed in parallel you should use a sequence, on Then 0 you connect Spawn Actor, on Then 1 the other lot of code

I might be wrong though, I am not that expert, only 4 months of experience

[trim matrix]

haha it's okay, yeah no i'm not talking about code in blueprint (and code execution order in general), i meant the constructor inside of the class that i want to spawn

[safe iron]

Ah

[trim matrix]

but thanks for the help!

[safe iron]

I think it spawns the thing first then it executes the code inside of it

[trim matrix]

yeah i think that's exactly what's happing in my case

[safe iron]

You would like it to execute before it spawns? On the beginning of the game?

[trim matrix]

i have to use a delay of one tick to get some of the functions inside of the class when i spawn them

[safe iron]

You need a delay of only one tick, right?

[trim matrix]

yeah

[safe iron]

I think that delay set on 0.0 should do the job

[trim matrix]

i can't use the "overlaping actor" node right after the spawn actor node, so i'm guessing that the actor is not yet been fully constructed

[safe iron]

IDK

[trim matrix]

ahh it's ok i guess i'll need to look up in the UE docs to get what i'm looking for (but i don't know the technical term for it)

[safe iron]

Yeah, otherwise Google will help for sure

[gentle urchin]

Or atleast its overlap is not considered untill next frame

Whats the usecase anyways?

[trim matrix]

i think yeah

[trim matrix]

just for general knowledge, i just need to know how it works in execution order before i play around with it 😄

[trim matrix]

Hi. I wonder how I can calculate the direction a player is moving in. So when moving forward he is at 0, when hes moving right he's at 90, back at 180/-180 etc..
And not take into account what rotation he has.

or 0-360 if thats easier.

not sure how you'll do that in blueprint but in c++ i used this:

 FRotator MovementRotation = UKismetMathLibrary::MakeRotFromX(PlayerCharacter->GetVelocity());```

@trim matrix *

pretty sure there is a "Make Rotation from x" node in blueprint

If I had a list view in my UE4 widget that looks like this: https://screenshots.foxy.rip/p9RAumzK

How would I make one of those list items tinted blue?

https://screenshots.foxy.rip/LSwKt6aB

@trim matrix Thank you thank you thank you! That worked perfectly!

All the class is is an image with some text on top

Anyone know how I would do it?

[gentle urchin]

doesnt the textblock widget get constructed ( so construction script is used?) Then you can use that to alter its looks i suppose

[trim matrix]

Uh

I update the list like this

And do this aswell

[gentle urchin]

Uh....

[trim matrix]

I have a request admin system in game to basically play a sound to all online admins in game, and then I want to make their name in that admin player list view blue

So just make that image tint blue

[gentle urchin]

guess you'd use the interface call you're already using then, since its called on tick

[trim matrix]

Huh

How, what do you mean

[gentle urchin]

you're already using the interface to update their names

you could also fetch their status, compare to whatever broadcast you got going for the sound , and use that to update the color/tint

[trim matrix]

Huh alright

Ill try and think of a way

Thx anyway

[lost solstice]

is there a way to check if an actor has a specific struct from a different component or class and modify it remotely?

[orchid star]

you mean if it has a variable ?

you can use interfaces to check maybe

or tags even

[trim matrix]

Any idea why this never hits when the value is -130?

[odd ember]

have you debugged it with breakpoints?

[trim matrix]

Nevermind.. I'm just a moron

[tight schooner]

@lost solstice I don't think there's a way to loop through all variables and get one by type. Like Koala suggested you need to interface it somehow, like make a function that gets it, or put the variable in a shared parent class and cast to the parent

[bitter helm]

I wonder how can I control animation rate with character movement speed

[trim matrix]

@gentle urchin Would something like this work?: https://screenshots.foxy.rip/bWSW7hlU

https://screenshots.foxy.rip/K8VlEAX2

I have an array of "admin requested players" in the player proxy which is set here: https://screenshots.foxy.rip/OvGKIZls

[gentle urchin]

Would appear like you're on the right track atleast

[trim matrix]

Alright

Cool, will test it out in VR and then will come back to you with the results :)

[bitter helm]

How can I control my animation rate according to the player movement speed?

[rose elbow]

is there an easy way to restrict character movement on a certain axis

[eternal reef]

The character movement component provides the possibility to constrain the moveable axis

[trim matrix]

Ok so @gentle urchin that doesnt work whatsoever

It plays the request admin sound like usual - but it just doesnt make the button blue

[gentle urchin]

Seems the struct isnt updated?

Erh, nvm

read it wrong 😄

[eternal reef]

blendspaces?

[gentle urchin]

I generally feel like this is more #multiplayer. What's the idea behind the list if i may ask? Are players able to see which admin is online, and request them ?

[trim matrix]

The player list is just a list of players in the game currently (that is updated every tick) that only admins can see in the admin menu widget

And then in the inventory widget which everyone can see - at the top there is a request admin button.

Right now, I have it so that when you press that button - it plays the request admin sound to all of the currently online admins.

So that all works fine - I just can't make their button blue that corresponds to their player

[eternal reef]

oof I hope theres a built in cooldown for that

[trim matrix]

Yeah

Added a 20 second one

https://screenshots.foxy.rip/7OPd4glX

Does that when pressed

Thats the conditions at the start to use the button

So yeah

[gentle urchin]

"their" button blue?

Sounds like you want the player who has requested an admin to turn blue?

[trim matrix]

I want their name on here

Where it says text block

[eternal reef]

I guess the position of the player is based on some sort of array
Which means if player 3 in your array requests support, pick the 3rd block in the widget?

[trim matrix]

The background to be white

[gentle urchin]

the players are already connected to the list

[trim matrix]

Yuh

[gentle urchin]

so all i think is needed is some bool in the playerstate to say if they're waiting for an admin

[trim matrix]

https://screenshots.foxy.rip/6W5PstQi

[gentle urchin]

bool, or enum , for "state" if there are multiple possible states (especially between admins)

Like "None" , "Open Request", "Waiting for assigned Admin", "In progress"

or whatever state is appropriate

[trim matrix]

Nah I just add their player state reference to an array https://screenshots.foxy.rip/ypM7VfaK

[gentle urchin]

Exactly

[trim matrix]

And then when the sit/request is done

I remove them

[gentle urchin]

Well...

dont you already have a playerstate array?

so all you need is a replicated boolean

"bRequestedAdmin"

[trim matrix]

Im so confused

Can you explain like I am 5 😂

Basically, right now this doesn't work at all: #blueprint message

[eternal reef]

Wouldnt you be required to constantly run the Event Tick for both, updating the list but also checking their state by this logic?

[gentle urchin]

Yes, the logic is.. interesting

rep notify would make more sense

[trim matrix]

[eternal reef]

Or only update when someone leaves, joins or sends a request

[gentle urchin]

Exactly

[trim matrix]

Well the main player list needs to be done on tick because of the way the modkit I am using works

It does have on leave server, on join etc but it doesn't work in this modkit as it should do

[eternal reef]

I mean you could do that with some custom events fairly easy

[trim matrix]

Yeah no I know

But I would like to keep my onTick logic that I have now

All I want to do is basically just when the player presses that button, target that specific player's button in the list view and set the tint of the image in the background to blue

[eternal reef]

This is now purely based on assumptions:
The players get put in your Widget List based on the position of the array
If this is true, you can just use their position in the array for the position in the widget list and colour it that way I assume

[trim matrix]

For the first point - what?! 😂

Uh

Can I not just like

Cast to the button which is used in the list view with the target as the players name or something?

Just speaking out loud 😂

[dire oyster]

hai
anyone know how to enable setting draw distance on a SplineMeshComponent so that unreal doesn't draw the entire spline at once?

[odd ember]

you'd probably have to loop through the spline

or not

[dire oyster]

the LandscapeSpline has that feature built in

[odd ember]

but you'd have to loop through to set it

since each mesh will have a different distance

[dire oyster]

all the meshes should have the same draw distance

[eternal reef]

@trim matrix
Uhh... no idea
To just clarify my point:
You have 3 Players in the Game
Player Array: Player 0, Player 1, Player 2
Your Widget retrieves those Players from the array and displays them in the same order
Which means Widget displays: Player 0, Player 1, Player 2

Now Player 1 requests help, he has the second position in your array and in your widget list
Thereby you can coloir the second position of the list blue

[dire oyster]

i tried looping over the static meshes but it doesnt let me set the DrawDistancr

[trim matrix]

Ahhh ok, yeah I think that might work

Do you know how I would do this?

Or even TRY and getting around to do this?

[eternal reef]

But as I said, this is just a guess
I dont really do much stuff with widgets so not really
Id first find out how exactly your widget list works and whether you can reference each single "block"

[trim matrix]

I do think list views work on indexes (I believe)

[eternal reef]

There must be some way to reference it I guess, but no clue, maybe someone else is more familiar with that stuff

https://docs.unrealengine.com/4.27/en-US/BlueprintAPI/ListView/

Seems like it has an index

[trim matrix]

Aha!

It does use indexes

https://screenshots.foxy.rip/HmnFWWSI

But then how I would use that is a mystery

[eternal reef]

No idea if this is really efficient, but:
Get the requesting player
Compare it with your array of players and see which position he is in
Use that index for "Get Item At" and I guess then just colour it

[trim matrix]

Oh shit

That would make a lot of sense wtf

[eternal reef]

And as there could potentially be multiple requesting players I guess you would need to create an array of "Requesting Players"
Check their position in the Player List and retrieve their position
Afterwards you have a list of lets say {2,3}
And you basically just loop through the array of positions that need to be coloured

[trim matrix]

Yeah I get that

That actually sounds great

But then when I get the element at that index

How would I change the color?

[eternal reef]

That is a very good question I dont have an answer for 😅

[trim matrix]

Ah alright

Lemme experiment hold on

Would something like this work do you think? (ignore the perma 0 index for testing purposes)

Then that custom event just does this: https://screenshots.foxy.rip/39vjcDS3

[eternal reef]

I mean you can just try it
Just make a fake player list that gets fed into your Widget and on begin play directly colour them blue or so

[trim matrix]

Well there is always gonna be a player (me) when I test it lol. Will test it alone in VR, will hook it up to my button and then test it.

Be right back.

[robust kite]

How do i change text on a button press?

[trim matrix]

Make the text a variable and use settext on the text element variable in the graph

Then set it to whatever

Like that kind of

[bitter helm]

@eternal reef sorry to disturb but can you tell me how can I increase the animation rate with player movement speed

[eternal reef]

So basically:
The faster you run the faster the animation should play?

[bitter helm]

Exactly

[eternal reef]

Do you use a blendspace?

[bitter helm]

Yes

[eternal reef]

And is it working? Because that should be handled by the blendspace basically

All you need is some animations like
Idle -> Walking -> Running
You set Idle to 0
Walking to 300 for example
And Running to 600
Use that blendspace in your Animation Blueprint and feed in your movement speed float

[bitter helm]

Yes

Wdym

Idle to 0?

Speed?

[eternal reef]

Like this basically

[bitter helm]

Oh ok

Then?

[eternal reef]

https://www.youtube.com/watch?v=ZL6pXqrKfc0

I think its easier this way

Ah your using a 3d blendspace, I mean playing around with the animations / speed values is best if you check a YouTube tutorial for that
Kind of hard to guide you through that here

[bitter helm]

💀

My character is sliding at 2000 speed

[eternal reef]

Is your character movement max speed identical to the max speed in your blendspace?

[bitter helm]

No

Let me try this tho

[eternal reef]

Doesnt make sense to set the character movement speed to 2000 but the blendspace handles values from 0 to 100 or so
The values need to reflect what you have set in your character

[bitter helm]

This seems to work

[trim matrix]

So Abaddon, dont know if your done or not but this doesn't work when placed in the widget which has the list view using this logic: https://screenshots.foxy.rip/L1UEirny

And there is always at least 1 item in that list view

So IDK what is going wrong lol

[bitter helm]

But why does my character start slow?

[eternal reef]

Acceleration
You usually do not want a character to instantly run at insane speeds

[bitter helm]

This is no regular human

I want him to reach 2000 speed instantly

💀

[eternal reef]

Character Movement, just edit the acceleration

[bitter helm]

Its at 2048

Hmm

[eternal reef]

Cant really help you out on that one
Maybe just make the widget appear instantly in editor and play around with the different settings available, have not really worked with this stuff

[trim matrix]

Fuck alright

Will look around.

[eternal reef]

What worked best for me is just look what the colour settings are called in the editor and search it when dragging away from that specific widget
usually you find what you need like that

[bitter helm]

@eternal reef It worked after increasing the acceleration

Thanks❤️👍👍

Maybe this vid helps you out
In the "ListViewEntry" he defines an Image and a Text, if you additionally add a blue background which is usually hidden and you just reference that and unhide it, wouldnt that work?

[trim matrix]

Uh

That sounds doable (ish)

Yeah

Right i'll try that in a bit

[plush wharf]

Is anyone able to get the "Export Anim Sequence" blueprint to work? Does anyone have an example of it working? It keeps crashing whenever I use it

[feral ice]

can you in someway set the time in timeline?

for example set the time to start at .5 and do the rest of the curve till you reach the end (which is 1 second in my case)

apperently not look at this for example

idk you might remember this from yesterday but trying to make a zipline

give me a min gonna record

sorry haha

so i want to set the time to start at 0.5 seconds

wait so i have to plug in the same var twice?

ok

gonna try that

is it bc i set it to play from start?

instead of play

sorry for the crispy video haha

i set the time to be 0.5 that means that it should start from the middle of the zipline

hang on, so i cant just set the new time inside the timeline block to 0.5 i need to use an extern block or node (dont know what its called) for that

oh that complicated

why is it so weird lol

alright

haha yeah

for the help

[eternal reef]

lmao

[feral ice]

haha 😄

[umbral ginkgo]

Why do the objects never equal each other when they should? I think it's because of the variable types are different and if so, how would I make it so they do equal each other?

[gentle urchin]

@feral ice isnt it better to provide the actual start vector, and not some midpoint lerp alpha?

[smoky marsh]

What's that component and what's the chosen one, and why in good gods name are you casting instead of using an interface

[feral ice]

sorry i didnt get a notification

What do you mean?

[gentle urchin]

Instead of doing some start time stuff, just provide the proper start vector ?

Not linestart but overlap location or whatever you're using to trigger it

[feral ice]

you mean so i lerp between the players location and the end loc?

[left fulcrum]

I am struggling to find the error here but it is supposed to tick every second and change the value for the cloud opacity, the starting value is 0.7 and the target is 6.0. So its suppose to start at .7 and go up by .1 until it hits 6.0 but it just between .8 and .9 like .8 .9 .8. 9 and so on. Does anyone see the issue here?

[trim matrix]

Idk what I am doing wrong, but I tried doing this: https://screenshots.foxy.rip/EPPrQXmq

And it just does not work

The blue layer/image just stays as hidden

[strong finch]

Wondering if anyone could help me with the attached? I'm trying to set up a freelook camera when holding ALT that allows you rotate around the third person character (similar to PUBG). Feel like this should be working and its driving me mad!

[smoky marsh]

Set up an interface, send an event to do what you want and then have the zoidbutton handle the event in its own blueprint

[safe iron]

fun fact, I needed it like 5 mins after you asked, so by asking you helped me XD

[trim matrix]

An interface?

Havent used those before on my own

[smoky marsh]

https://youtu.be/SMjvprnjL-w

Casting is pain, don't cast

[trim matrix]

Yeah, a lot of people tell me to use casting all the time - and it only works like 20% of the time

Legit

[feral ice]

I think i see what you are getting at here

[smoky marsh]

Casting is pain unless casting to a c++ class

[left fulcrum]

What do you mean lorash? It comes right out of the addition node

[trim matrix]

Someone explained to me that casting is how you talk between different actors 💀

[smoky marsh]

It is, but it's like if I asked your name and you shouted all your information to me, like everything

[trim matrix]

Jeeesus christ

https://screenshots.foxy.rip/kRNsZQ4I

[smoky marsh]

Unnecessary amount of data

[trim matrix]

Do I add my custom one here?

Oh shit ok 😳

Oh alr

[umbral ginkgo]

Component is overlapped component in On Component overlap (trigger). Chosen one is whatever trigger is chosen and Im not sure

[trim matrix]

Do i add my interface here

[smoky marsh]

Well, object goes in, entire object goes out if its the same

Which tends to be overkill

The ue5 demo animbp is like gigabytes in size for no reason due to a cast

[feral ice]

The location will be different and to lerp between end and players pos will result in different speeds. If the player is 10000 units away the speed will be 10000units/second. If the player is 100 units away the velocity will be 100units/second. Thats why you said that ysterday that i need a set velocity so whever the player is the speed will remain the same. Gonna try it your way.

[gentle urchin]

Thats why we adjust playrate*

playrate compensate for lerp distance being different

takes speed into account

[feral ice]

ok gonna have a look if this is easier

how many times it should update?

no thanks haha

haha

[gentle urchin]

Interpto would work aswell, but requires some manual checks

[feral ice]

i feel like i know to little to use interpto constant and interpto. Gonna have to read and watch a video on how to use it properly

ok

gonna send a reference video if thats ok

im trying to make it look like this, i misspelled together

thats true about the acceleration but ill start with just getting it to work the speed i will deal with later i guess

[gentle urchin]

The timeline could accelerate it

[feral ice]

but cant i just mix with the playrate

[gentle urchin]

Just by editing the curve

Not very flexible by variables tho

[feral ice]

yeah ok

well i have to divide this into sections

[gentle urchin]

Curve always starting at 0 would give you predictable acceleration, but would account for any existing speed

Interpto is surely better overall in this scenario i think

Yeah valid points

The original request didnt mention acceleration (or zip-jumping),

So its just guesswork when proposing anything really

[robust kite]

it works thank you 😊

[last tangle]

do inputaction's only work with one blueprint at a time?

i have an inputaction connected to two different blueprints but only one works at a time

[maiden wadi]

If you don't uncheck Consumes Input on the event, yes.

[last tangle]

how do i do that?

[maiden wadi]

Click on the events in both blueprint and check out the Details panel.

[last tangle]

okk!

[trim matrix]

@smoky marsh/ @trim matrix back to my interface thingy, if I try and do this but want to access the event in the zoidhelpbutton widget event graph, what the hell do I put in my target?: https://screenshots.foxy.rip/f3TGrGAa

This is what is in that widget's event graph

[indigo bough]

Hey folks, just a question about blueprint components. Is there any other way to attach data to a primitive component other than component tags?

Asset User Data seems like it might be what I want, but I can't create new classes of that in a blueprint-only project 😦

(Specifically data that can be accessible within blueprints, not the material)

The dream would be to provide a reference to another component belonging to the same actor, along with some int/name variable.

[dawn gazelle]

You'd need to input a reference to the thing you want to execute the interface - so if it's a widget that is going to execute the code, you need a reference to that widget to feed into the interface call.

[trim matrix]

So would I just make a new variable called like the blueprint name

And then that's the reference?

[dawn gazelle]

Nope. That would only be a variable that can contain a reference to a widget and not the actual reference to the widget unless you set the value of that variable to the widget that will be executing the code.
It's like if you had an integer variable, but never set it's value, it'll always be the default value of 0. Unless you set the value, then it wouldn't point to the actual value you're wanting.

[trim matrix]

So how would I 'reference' that widget then?!

[runic parrot]

Hi! i'm attaching one of my cameras to one actor and i want the camera rotation to stay the same and the position to move along with the character. The problem i'm having is that the camera rotates with the character.
Am i missing something?

[dawn gazelle]

How are you creating the widget? If you're using the create widget node, then that gives you a return value which is the reference to the widget.

[trim matrix]

The zoidhelpbutton is used as an entry class in a list view as shown here: https://screenshots.foxy.rip/hhKarnHD

[maiden wadi]

@indigo bough I don't believe that's possible without some framework. If you want another component's data from the same actor parent, you could just use GetOwner->FindComponent. There are a couple of ways to filter components, FName Tags, Class, etc.

[runic parrot]

Found it, i needed to remove the "inherit pitch/yaw/roll" on the spring arm of my camera.

[trim matrix]

So @dawn gazelle how would I reference it?

Or at least one of them

[dawn gazelle]

So you provided a screenshot of the parent widget. I've not really messed with ListView objects, but you'd have to get the Listview_148 object, and then get the reference to the specific item in the list you're wanting to change. Something like this. The return values would be the reference to the actual widget object.

[sand wasp]

how would I sort an array of Blueprints after their priority which is an integer?

[indigo bough]

Thank you, yeah getting the components is relatively easy, but I'm trying to set up a animblueprint script which sets two bone locations based on the world location of another component, however I need to set which two components this animblueprint should be getting the world location of.

So far I've been using component tags, basically two component tags on the first object which correspond to 'target' component tags.

If component tag 0 = "A1", Find component with tag "Target_A1", get world location.

The problem with this is it's just a web of component tags, especially when something is both a target and a source 😦

Perhaps a custom Asset User Data is the only way,

[trim matrix]

But basically how my thing works is that the thing I am running using this interface is called from a different widget

https://screenshots.foxy.rip/idAny2s5

That button in one widget

Calls that interface-based event inside of the zoidhelpbutton

The event never touches the parent widget's event graph

[dawn gazelle]

Doesn't matter where it's called from. In order to use an interface you need a reference to the object itself that you're wanting to run the code on.
How you get to that is up to you and the logic you have and what you have to work with.

[trim matrix]

But how I go about getting the reference is the hard part for me

[dawn gazelle]

And it's the next to impossible thing to explain as it all depends on how things are set up for you specifically.

[dawn gazelle]

Like if you have a master "window" widget, and that request admin button exists on it, and if there's another widget that contains the list that exists on that master, you use the master window to find the reference to the list.

[rich granite]

Ah, another day, another bug.

Yesterday I saved and closed Unreal with my player movement working perfectly, and when I load up the project today, the player doesn't move.

It'll change direction, but velocity prints as 0.000,0.000,0.000 :T

[trim matrix]

Basically, I have one widget with the admin button thingy, and then in another widget I have the admin player list (the blue listview 148)

And I need to access one of the buttons inside of that list view

Which the class is called zoidhelpbutton

[rich granite]

Er...I just fixed it. Apparently turning on physics prevents the AddMovement node from working.

[trim matrix]

I just want to make an image layer visible when a button is pressed in a different widget basically

So e.g:
I press the request admin button:
- The corresponding player's button in the admin panel widget turns blue

[desert juniper]

Very rarely are you going to encounter actual bugs with the engine like that
They are almost always user error, as you found out

Your best bet is to use version control to revert back to a time in which it last worked, and work your way up forward to there

[trim matrix]

What would I do Daytura?

[pure bridge]

Ray cast car suspension the rays go side ways what to do

[flat coral]

You're closer but I might ask in #legacy-physics if I were you. But note that this is a question a little off the beaten path for most of us, don't be surprised if it takes you longer to get an answer than the average person tripping over some standard blueprint bullshit. It's a little esoteric

[trim matrix]

Was you going to say something Daytona?

[rich granite]

Scenario:

The actor class Enemy_Base has a vector variable called Knockback.

The player is hit by actor class Enemy_Base_Child.

Can I simply cast to Enemy_Base to get the value for Knockback?

Instead of casting to Enemy_Base_Child

[trim matrix]

Bro you still typing 😂

https://screenshots.foxy.rip/9tgFguxZ - I don't know what you are trying to say here @dawn gazelle but it should really be a bit simple, I just want to be able to reference ANOTHER widget from one

Shouldn't the solution be a bit simple?!

[dawn gazelle]

have fun figuring it out.

[trim matrix]

uh

did I do something 😂

[dawn gazelle]

Well it's simple right?

[trim matrix]

yes but no

For others it should be, but I cant figure it out for the life of me

[dawn gazelle]

So what makes you think that I am any more an expert than you? Perhaps I'm taking some time to actually think about your problem, and properly construct something that could help you?

[trim matrix]

I'm so sorry if I came off as impatient - I really am trying not to be, it was more of the stress of not being able to figure it out that kind of made me say that.

I apologise and would accept any solution/help you can give.

[dawn gazelle]

Rule #2 in the discord my dude... Be patient.

[trim matrix]

Yeah - i'm sorry 😂

[dawn gazelle]

Now, how I would approach your problem is much different.
I would have an "admin state" as an enumerator replicated variable in the playerstate. It can have 3 possible values: StandardPlayer, AdminRequested, AdminPlayer. By default, the "admin state" should be set to "StandardPlayer".
When a player requests admin by clicking your "Request Admin" button, the RPC goes to the server, and the server sets the "admin state" on the appropriate playerstate to "AdminRequested"
Your list view widgets should likely be generating from the list of playerstates, so from that, you should be able to pull the "admin state" value and you could just bind to the "admin state" to change the appearance of the buttons.

No needing to call one widget from another, just simple variables changing that then drives changes in other widgets.

[trim matrix]

How would I do the "enumerator replicated variable in the playerstate" part?

I get everything else

[dawn gazelle]

You create an enumerator like so. Double click and open it after creating and you can set the values.

Then in your playerstate, you can add a new variable of the type of whatever you named your enumerator.

[trim matrix]

In my player state?

[dawn gazelle]

Then you can set/get the value by referencing that variable.

[trim matrix]

Is that the name of the enumerator

I dont have a player state, I have a Player Proxy as I am using the Pavlov game modkit

So all actions run on the player would be in the player proxy

...right?

[dawn gazelle]

I'm not familiar with it.

[trim matrix]

But then how would I access the player state?

[dawn gazelle]

Based on the video I found, the "player info class" is a wrapper for the playerstate.

So you'd put that enumerator in there.

the player proxy is the pawn of the player, or the thing they are controlling in the game.

[trim matrix]

How would I access the player info class then?

[zenith trout]

what happend why is my camera so weird what should i do??

[dawn gazelle]

Couldn't tell you. That's specifically to do with that Pavlov kit.

[trim matrix]

Alright

[sand wasp]

how can I sort an actor array by priority/value inside the actor?

[gentle urchin]

Loop it -> insert in a cached array at the right spot -> return cached array

[odd ember]

find a heuristic to sort by

and pick a sorting algorithm

doesn't array by default implement a quicksort?

[sand wasp]

this?

[odd ember]

I've never seen that but there you go

[gentle urchin]

Damn

Thats new

[odd ember]

I don't think it's standard

[sand wasp]

ive never seen it either

[gentle urchin]

Would be nice if it was

[odd ember]

the heuristic is the comparator anyway

if you pull that out and use CreateEvent

you can create an event that compares values

[sand wasp]

not that I would know how to use it

[odd ember]

you have to use some sort of heuristic

a value

just comparing actors or objects isn't going to give you anything

if you have values stored in the actors that's good enough

[sand wasp]

how would I do that tho. I have an int in the actor which acts as priority

[gentle urchin]

How would one return a result?

[odd ember]

cast to your actor

find the int

compare the ints between A and B

[sand wasp]

and how do I put it back into the array?

[odd ember]

no clue, I thought it would be by ref tbh

may still be

maybe the custom UI doesn't distinguish between ref pins and normal pins

[sand wasp]

wait so how do I put them back sorted into the array after getting the int from Object A and B?

[odd ember]

consider it done for you

that's the simple explanation

[sand wasp]

just a step in the right direction...ill figure it out by myself

[odd ember]

aha: https://answers.unrealengine.com/questions/848158/blueprint-array-sort.html

so it needs to be a function

not an event

look at that thread

[sand wasp]

why did I never find this. I looked for a question on the answerhub but didnt find it

thansks

thanks

[odd ember]

literally first result on google

[dawn gazelle]

I can't even find that node <_<;;

[odd ember]

it's low entry

whyzat CE?

[sand wasp]

I kinda tried something similar but I always failed on an infinite loop...I really have issues with for each loops. May I snippity snap this?

[dawn gazelle]

Fixed again.. lol (And yes Cascade you can use this)

[odd ember]

because look at the spaghetti you have to make to make it work

[sand wasp]

hm u really dont like spaghetti do u

[dawn gazelle]

Yea in a function it kinda sucks. If you had it out in the event graph you could call an event to break it XD

[odd ember]

only for eating

not for unwinding

[sand wasp]

fair enough

[flat coral]

The problem with an infinite loop is that the Tick function is already a place to run code on an infinite loop

[odd ember]

it's not an infinite loop

it's breaking the loop

[flat coral]

Like that's what tick is, every time the whole sim loops, tick gets called, forever

my rule is only break a loop with a return

Like if you're looking for something in a list, it's cool to break it when you return that.

[odd ember]

if you return you don't need to break

[maiden wadi]

Things like that make me love C++. 😄 As a UI person Array.Sort( {} ); is far too fantastic.

[odd ember]

aye, I believe that's what they tried to do in LE

[flat coral]

Well, you're still breaking the loop, just not using a break statement

[odd ember]

with the comparator

[gentle urchin]

Couldnt one make a bool for break in the macro instead

[odd ember]

you'd still have to set it

[gentle urchin]

True

But no return wires

[odd ember]

you'd still need the wires?

[gentle urchin]

Would look more like how youd do it in cpp i guess

[odd ember]

oh you mean like the bool would be checked

[gentle urchin]

Y

[odd ember]

every loop

hmm

[gentle urchin]

Basically let the macro check the bool with an 'or' statement for the length of the array

[gentle urchin]

Seems to work. Drawback is the extra bool handling

[rustic kettle]

Any recommendations on what to learn for creating a advanced locomotion system?

I've got a question. I'm using Third Person Character setup and I disabled UsePawnControlRotation on the camera boom and the camera, but the view is still rotating when I move the mouse. Is there something else I have to disable?

[odd ember]

mouse input for camera?

[hardy merlin]

That's disabled too

[faint pasture]

This might be more of a design question but it kind of gets into blueprint. I have a vehicle building game much like Kerbal space program. I've been thinking about how to do the controls. Right now, I just have direct mapping from input to vehicle parts which respond to that input, and the vehicle part is configurable by how much it responds.

I'm thinking about making it a little bit more flexible and diagetic. I would like vehicle part controls to be wired up in as simple a manner as Minecraft's Redstone or GarrysMod WireMod or Starbase.

Here's my current idea. Every part has named control fields. Every field is in the (-1,1) range. A wheel hub might have Brake and Steer, while an engine would have Throttle, a clutch would have Engagement, etc.
In wire mode, click-dragging from a part to a part creates an output->input connection (wire). The simplest vehicle would have direct mappings from the cockpit (Brakes, Throttle, Steering) to the vehicle parts, while a more complex setup would have intermediary ADD and MULTIPLY and AVERAGE (along with others) nodes. All the nodes exist as physical parts (ECU) and can be damaged.

Does this seem like an ok approach or too complex?

[terse elm]

It's worth knowing how much WORK ksp's SAS is doing to keep your rocket going in the right direction when CoT and CoD don't line up with the direction of travel

It'll automatically vector your thrust to compensate for torque on the vehicle and keep it both going the right direction AND aligned correctly

And it's very difficult to play without it

[high ocean]

Any chance I can modify these EDs to also send the refs of the buttons pressed (w/o cpp)? This is an edited template I made creating a bp class from the button class of the engine.

[flat coral]

You could make a custom button class that wraps Button and dispatches a custom event that includes the param

[high ocean]

yep, that i know 😛 so, basically no, not w/o cpp i take it.

[flat coral]

wiat no you can do all I said in BPs

[high ocean]

all u said i know, I have those setup

[flat coral]

I'm so confused where you think C++ factors into this

[high ocean]

well, i'm guessing I can edit these EDs in their source and change them in the engine (like I change my foreach loop to always also have a start index)

i'd like to have this on all button event dispatchers - send their refs. Then again, now that I think of it, it's no use lol Jesus I'm dumb... 🤦‍♂️

nvm, thanks @flat coral 🙂

[flat coral]

Glad to help?

🙂

[high ocean]

I have this mess here, made by my "artist" 😒 and ofc the buttons are overlapping, So I just wanted a quick fix, when I hover any of them, get their refs, check against an array of the others and set the others as hit invisible to avoid situations in which the player clicks on the overlapping area, the button is ofc hovered, but the click doesn't go through for either and it looks like a sloppy bug

or I could just search for a proper artist and do what I actually asked: 2.5D view+extensible of a trippy/darkcloister interior - nvm...

[gentle urchin]

Sounds like avoiding overlap is a better fix 😅

[flat coral]

Yeah it seems to me that fixing this problem is like 20x easier than whatever you were about to do lol

[high ocean]

gimme a God damned artist, been struggling with the one I "collab" with, hoping he'll get better - he doesn't... and never listens

I love that pov! And some of that style

Guess im glad i didnt finish my game?

Was named thronebreaker

Totally random

But yeha getting decent people to collab with can be troublesome

Quite a few half doers

They're still better than no-doers but sigh...

well, I've struggled to teach/even studied for him and send him bits and pieces, did research, feck me i learned 3D myself in the process - he still sucks at 90% of the stuff - We're talking 3 years man... srsly. Anyway, gave up on him totally, so I guess I'll need to find me some illustrators to make some stuff. The rest falls on me 😦

[high ocean]

now THAT is something i hate from the bottom of my heart! Better say you won't do it than make a mockup of the work...

or at least listen & take into account my references. I send you a flower and you draw a dragon - like wtf. Then they're like "well, i thought it'll be more suited" lol wut?!

On an unrelated note im gonna do my own path correction since navmesh doesnt give me what i want

Getting way out of my original scope for the movement but oh well

I want it nice

Correcting it with a ton of linetraces 😱😫

[high ocean]

Oh wait... wtf, this is weird. Overlap isn't the problem, the click doesn't fire in this area o.O

any ideas? I'm out of ideas 😐

[gentle urchin]

Daym that looks oddly specific

[high ocean]

so you are virtually correcting the movement based on math done on distance from trace hit to the moving actor? 🤦‍♂️

that's a whole lotta work man 😄

[dense yew]

Hello, does anyone have an example on how to code a projectile that will hit the clicked mouse location with a parabolic trajectory (easiest behavior example would be Ziggs' bombs).

[gentle urchin]

Im doing double linetrace along the face of the landscape^^

If it hits, i add a path point and adjust my new trace angle according to the face i hit

[high ocean]

oh but that's not so bad, I imagined many traces at various angles (porcupine-style) around the character to correct trajectory... on tick 🤣 Seen that somewhere on some free marketplace stuff - think it was flight nav. Was funny

[gentle urchin]

😂😂😂 on tick for sure

Jk

Its done once per path request

Shouldnt be horrible but maybe

Depends on how oddly shaped the landscape is

Mostly flat so not gonna give me a ton of points

Worst case would be the amount of faces over a given distance , if all faces had a different direction/rotation or whatever you'd call it

[high ocean]

@dense yew *ue4 parabolic projectile *on youtube returns a fair amount of results
Try this short one - nothing to loose, it's 6 mins
https://www.youtube.com/watch?v=Zhz20-_loWQ&ab_channel=UnrealSolver

[flat coral]

Though if they want it to be angled up so that it impacts where the cursor is, that's harder...

[dense yew]

yeah I can get a parabolic trajectory working and make it shoot towards my cursor

[flat coral]

Have you considered that, with a fixed projectile speed/weight, some objects will not be hittable with it?

[dense yew]

what I cannot figure out is how to make it hit the exact cursor location

[flat coral]

What i'm saying is there is a max range to account for

[dense yew]

oh yes, sorry was caught up reading. There'll be a max range

trying to make a grenade work in an isometric camera, or MOBA style

[flat coral]

also even with a fixed projectile speed, for almost all distances there will be two possible paths

[gentle urchin]

Direct and indirect, sort of

[flat coral]

like if I can throw a baseball 1 kilometer (being conservative), if you're 100m away from me, I can either throw it towards you with a slight upward so it hits directly, or I can throw it almost 1km into the air (again, being conservative with my abilities) so it lands where you are

[gentle urchin]

Usually you'd want the shorter path ^^

Unless obv obstructed

Or low accuracy

If any of the latter then the long route may be more desirable

[flat coral]

Exactly my point, especially regarding the obstruction

So all this is tricky fuckin math... except there's no way in hell that's what like League is doing. They are for 1000% sure, faking the shit out of this.

[dense yew]

Mhmm, I see, let's say for now I want only want it to collide with the ground

yeah, I want the league cheat hahahahahahaha

[gentle urchin]

The math isnt that complicated tho

[flat coral]

All you do is send it from A to B on a straight line, and then have the height of it given by a parabola that you have stored in a curve somewhere. And then you scale the parabola by the distance, so farther shots go higher

[dense yew]

hmmmmmmmmmmmmmmmm

[flat coral]

That's not like the real math but it's close enough that anyone would have to squint real close to see how it was wrong

[dense yew]

that's much more clever than what I was attempting with real math

[flat coral]

I'm in camp Fuck Math

(haha jk I've done so much goddamn math for my game)

[dense yew]

gotta admit, I'm actually a vfx guy, so I want to learn projectiles so i can make some fancy stuff

next on the list are projectiles with random trajectories

[runic parrot]

Hi! is there any way to get a random point (vector) given a collision box?

[gentle urchin]

Random point in box?

[dense yew]

thank you @flat coral @gentle urchin

[winter kettle]

I have an "OnHit" event that is triggering before "BeginPlay" on an actor blueprint

is there a way to fix it?

[flat coral]

WAIT NO mine is for a beam trace 🙂

[brazen merlin]

have it not register hits by default, then set it so on begin play

[dense yew]

let me show what I mean by random as well

https://gyazo.com/ba30d474e2f0571d2aa9c176839918c2

[runic parrot]

like a charm, thanks!

[dense yew]

Also saved those screenshoots, I'm sure they'll help me hahahaha

[flat coral]

Also it's worth knowing when to physics something and when to fake it

[gentle urchin]

This is with homeing 😂

[gentle urchin]

They are custom functions 😅

Grinnings idea will work for the randomness tho!

Just rotate the curve 😄

[flat coral]

The advantage to physics is that it will look 100% right to the viewer and is pretty easy to do usually. But the disadvantage is it can be very difficult to tweak for gameplay purposes

[dense yew]

Thank you all, will be sure to show the results later

[flat coral]

For example if you wanted to increase shot-to-target time by 30% for gameplay balance reasons, with the physics approach you could be back to the fuckin drawing board with the math. And there will be an odd, parabolic relationship between target distance and shot time

[dense yew]

Yeah, I thought about that too

[flat coral]

But with the "fake it" approach, you can just make the speed a float and have it in your calculation as a constant

[dense yew]

it looks good enough as well

[high ocean]

y not have a single trajectory on a spline (or whatever, a few splines which get selected), pick points in it's proximity with a certain variation and spawn splines connecting those points, then have the projectiles follow them? Idk, It's how I'd approach it, but I'm bad at programming & physics, so maybe I'm talking smack 🤷‍♂️

[flat coral]

Often the right approach is to separate the gameplay and visuals a liiiittle bit. For example, weapon that APPEARS to shoot a super fast projectile, for visual purposes, but is actually hitscan behind the scenes and the projectile doesn't DO anything

[dense yew]

I've been learning that slowly

[icy dragon]

At least in GTA V and maybe COD games, that is the case

[dense yew]

Miniguns are one of the greatest lies in videogames lmao

[flat coral]

Because like... if how it looks and how it plays are inextricably linked, what do you do when it looks good but feels wrong, or feels good but looks bad?

[high ocean]

I don't even bother with projectiles in my game (not a shooter/projectile focused tho). I just spawn the emitter when a skill is shot by a bow, then the emitter on impact - looks decent, if it doesn't even give it more impact

[flat coral]

The ability to tweak the look and the feel separately is often important

[dense yew]

eh I'm learning projectiles so I can control the trajectories

and apply it into the game i'm working on

[flat coral]

I guess the questions for you are things like "should terrain block the projectile realistically, or in a more abstract way?"(eg no shooting around lane edges) and "if the target is on a higher elevation, does the projectile impact sooner or is the weapon always the same shot-to-target time by distance?"

[dense yew]

yep

I'm currently working on a tower defense so it's even a tad simpler

but there's still some height variations

[flat coral]

I'm doing something that is SUPER physics-based, but even I'm often finding that the separation is still necessary

[dense yew]

we'll have to deal with that when we start applying some crazy trajectories

Also I pretty much love physics in games, hopefully in my next game I'll be able to work with ragdolls and destruction 🙂

[gentle urchin]

@dense yew If you wanted whats inside the node

[dense yew]

Oh I recognize the formula

[high ocean]

I just can't get it, can't find anything on the internet either. My button - and only that button - doesn't trigger when pressed in that particular area.

[dense yew]

Thank you

[gentle urchin]

At that point, just make a custom button class

and watch how the mystery resolves itself

[high ocean]

but the exact same button class works for all the other buildings 😮

i even looked at the texture - no difference between them, none...

[gentle urchin]

someting else lives in the widget space?

[high ocean]

nope

[gentle urchin]

override

[gentle urchin]

on mouse enter

and on mouse leave

and see if it responds

[high ocean]

they work 100% perfectly

[gentle urchin]

but do they respond within that given circle?

[high ocean]

the click even sets the state properly but won't fire the ED

[high ocean]

yes

[gentle urchin]

as in, the mouse never leaves the button?

[high ocean]

i'll check, fair point

[high ocean]

nope, it enters, only leaves when I click, but doesn't fire the ED

[gentle urchin]

erh

should it leave when you click?

sounds odd

[high ocean]

i know... I don't get it

and if it left and I keep clicking all over the button, at a certain point it will "enter" again - nothing predictable tho...

[gentle urchin]

Sounds like

hmm..

click method?=

[high ocean]

up & down for all

meh, lemme try down only

[gentle urchin]

or precise click

I've seen weird things with the default button tho

[high ocean]

yyyep, i'll just leave it on mouse down click method, it fixed it 🙂

thanks! 😄

[gentle urchin]

weird, but good i suppose

[high ocean]

I don't even care it isn't "standard"

[gentle urchin]

custom buttons are safer imo 😛

[high ocean]

cpp custom buttons or?

[gentle urchin]

nah just userwidgets representing a button

[high ocean]

just some borders with images and EDs on click - ye, meh, I could do that...

[gentle urchin]

exactly

[high ocean]

the bonus is they will even work with drag & drop

buttons don't

[gentle urchin]

Exactly

buttons can,. but needs some special special handling

Mouse enter and leave is just hover,

and a few overrides

[high ocean]

lol my hover is a FL function for all buttons

[gentle urchin]

well daym

[high ocean]

but never thought to do it like that, u got a point 🙂

[gentle urchin]

has worked great so far atleast

probably got it wrong with the focus part but im not doing gamepad controller anytime soon

you can ofcourse make dispatchers for every event if you want the main widget to handle it somehow

[high ocean]

• it's easier to set states for them if you don't do - idk how fancy you'd need to go to require that whole state struct.

[gentle urchin]

never used the state struct 😂

[high ocean]

figures, it's a pain in the arse really

[gentle urchin]

in my case the click event relies on mouse button up, after being down

[high ocean]

expecially for dynamic buttons -fml

[gentle urchin]

and if it were to trigger clicked, i just forward it aswell

[high ocean]

ye, saw it

[gentle urchin]

That is all, aside from the variables for setting it up

[high ocean]

but that's a good idea indeed. My next project i'll use custom ones instead

[gentle urchin]

clearly more can be added

[high ocean]

well, u make a class ONCE and have it forever really

[gentle urchin]

Exactly

[high ocean]

now here's a nice use for that feature in ue5 for adding modular feature packs - things like this

[paper hornet]

How can you setup variables on the gamemode blueprint? Like, I got the variable setup but I don't know how can I set up its value on?

[icy dragon]

Any reason to specifically doing it on Game Mode?

[paper hornet]

Not really. Perhaps you can point me a better way? I have a camera setup in the scene. I just want that when the game starts it set itself as the camera of the player. I know I can reference objects directly in the level blueprint, but I figured out that the camera was somehow related to the gamemode? Given I could have multiplayer (multiple cameras?)

@icy dragon I'm quite new, so any feedback is of help

Like, what if the camera is diferent on that level depending on the gamemode you are willing to play?

[icy dragon]

Typically you're dealing with Pawn and not directly to a camera component.

With GameMode, you set the default pawn to spawn and possess, as opposed to have already placed pawn auto possessed (and won't work on multiplayer scenario)

[paper hornet]

Humm right, so what if I wanted to control a pawn that's on the grown, and have the camera above it (think this)

How can I relate the top-view camera with the player-controlled pawn (tank) ?

[icy dragon]

I'm thinking to have the pawn to have the saying on what camera to be set active, as opposed to the game mode.

TBH I'm not that versed on #multiplayer

[paper hornet]

Right, makes lots of sense for single player. Thanks mate!

[dense yew]

@gentle urchin @flat coral thank you! Got it working: https://gyazo.com/24f5182d8e8158673e7047143da7b3f7

now time to work on the vfx itself lmao

[paper hornet]

https://tenor.com/view/we-shilling-solobolo-chilling-gif-20822233

[dense yew]

also some vfx showoff there with the gunshots, heh. Have a great night

[spice smelt]

is there a way to have a field in the details panel which accepts a class's method pointer somehow? Or better a blueprint library's function

[faint pasture]

As with everything in life, you get what you pay for.

[high ocean]

@faint pastureWe got the same money man... The game we made was on a grant. Not big money for either of us. I ended up doing 80%+ of all the work, including his. Cos he was a "slow learner"... But yea. I sucked bad, I learned hard. He... didn't, so that's that, i'll just do all of it myself this time 🤷‍♂️ I have no thousands of $$ to sped, I'd like to but don't.

[odd ember]

do you pay your artist?

[faint pasture]

You have the start and end points, there are up to 2 solutions to the initial velocity. Choose the shallower one.

[odd ember]

oh I see

[high ocean]

@odd emberI wrote the damned grant... So yea, I paid his salary for 2 years 😔
