i tought i need this to tell the vector points where there startin point is

but i reference the camera in the forward and right vector alredy i guess?

[dawn gazelle]

Right. And then your starting position is wherever your character is

thanks alot man, really appreciate it

Quick Question. I have this Widget with an image and I want to change it but even though the function Set Brush From Texture gets called with a valid texture and the object reference of the Image it doesn't change from this checker Texture I set. What do I do wrong here?

Maybe it does need a specific format or something like that? But I don't get a warning or error by calling the Set Brush From Texture function which I thought would happen if there would be anything wrong with calling it

[sonic cipher]

i'm noob but can't you set image instead of "brush" ? lol :v

[brazen jackal]

I want to change the image at runtime

[dawn gazelle]

That's the right way to do it, but you're probably not feeding a texture properly.

[brazen jackal]

ok but where could this get wrong? Is the texture wrong? Because I have just a path to a texture which is already provided from Unreal, I didn't make it myself yet since I just wanted to try this out

[dawn gazelle]

Where are you calling the set image function?

[brazen jackal]

This is the texture I'm currently assigning

[dawn gazelle]

Example of how to use the function:

[brazen jackal]

Hm... bit comlicated. It's part of an inventory. I have a cpp class derived from UUserWidget and IUserObjectListEntry to have a list entry for a tile view. When I open the Inventory the tile view will get filled right here

Hm... my Visualize Inv Item Info pretty much does that.

[native plover]

no the hand goes to the right when it shouldn't

[native plover]

nothing to do with camera

[dawn gazelle]

So you need to trace back where your data is coming from.

[brazen jackal]

the data is this #blueprint message I see the path to this texture when stepping through the blueprint

[brazen jackal]

yeah all that gets called VisualizeInvItemInfo->SetImage

[dawn gazelle]

The data is coming from the Get Inventory Item for Cell, which I don't know what that contains, and that looks like it's being fed from the widget itself. Again, you need to trace where things are getting set. You do have the function set up right. It works fine on my end, you're just not passing the image data to the widget.

[brazen jackal]

and in SetImage I can see the Image texture is the path to the logo I posted earlier

But if it's not set up right I wouldn't get the right path to the texture path in the SetImage function won't I?

This is the texture path if I step through the function which should set the image

Shouldn't be important where the data comes from if it is right. But I can show you where the data is from.

It's pretty much just that property which will get passed around a bit. I already traced that through the whole thing to the end

it's an actor which I can collect in the world

[dawn gazelle]

Just try this.... On your set image function, break the image texture pin, and manually place a texture there, and see if it works. If it works, that means your function that you originally asked about is working correctly, and it means you need to troubleshoot how your data is being fed in. If it doesn't work, then that means it's probably a faulty image or some other oddity (multiple widgets overlapping?)

[native plover]

can anyone help me with this?

[brazen jackal]

thanks I will try this immediately

[faint pasture]

Where would be the place to put a global event listener? Like if I wanted to make an "action" meter that's driven by total DMG done globally

[brazen jackal]

Unfortunately this didn't do anything. I will go to sleep, maybe I will have an idea tomorrow. Thanks anyway

[zealous moth]

Assuming that the Skeletal Mesh Component and the Camera Component are both Actor components, is there a way to access the component itself if assigned to a variable in order to obtain the transform? Or are they not actual actor components?

[dawn gazelle]

Yes

[zealous moth]

ah i see, they are scene transforms, not actor transforms

[dawn gazelle]

You have them as variables right now on your screen

[zealous moth]

no no, i meant what do they inherit from to obtain the transform

[dawn gazelle]

ah

[zealous moth]

they are scene components

not actor components

the latter are abstract, no transforms

Hey, does anyone here know how to spawn a single sound cue without overwriting the current sound that is played, when reusing the cue? I am playing gear sounds while running but since they play every few seconds, they stop the old one and just play the new one, it sounds really cut off, what would be the best approach to play the same sound que with different sounds, while not overwriting the sound cue, but letting the old sound finish and blending/putting the next/new one on top?

[dawn gazelle]

You'll probably want to create a concurrency setting for the sound which allows you to control the number of instances any sound using the setting can exist.

Anyone know how I'd enable dual-wielding? I followed this tutorial. DM - Thank you. https://youtu.be/0GlC4z7LIWU?t=955

[dawn gazelle]

Not sure I 100% understand but do you mean passing something to the construction script?

[olive sedge]

@dawn gazelle yes

I do SpawnActor and I need to pass an argument right away

[dawn gazelle]

Oh, then create the variable that you want to set and set it to "expose on spawn" and "instance editable". When calling the spawn, you can feed it the value.

[olive sedge]

@dawn gazelle ah! perfect! thanks

Why are my macros getting pruned after updating to 4.26? 🤔

I can't use macros in my anim graph or they get this pruned warning

New Macro was pruned because its exec pin is not connected

[edgy halo]

How do I create an array depending on some input from user?

And a square shaped map

[edgy halo]

And the dimensions of the array are these

[dawn gazelle]

Sorry yes, it shouldn't be colliding. Perhaps there is more to the object? Like is there a static mesh component as well as a collider?

[dawn gazelle]

If you are going to set the array to a specific size, then you need to use set array elem to set its members.

[edgy halo]

Ohh

Is Blueprint debugging unstable?

I'm trying to debug one and things crash. Things don't crash if I'm not debugging.

[steady apex]

When I spawn a cable component using BP, it swings around a lot before it calms down. I suspect that's because I'm setting the end locations AFTER I create it. Is there a way to prevent this?

[exotic cradle]

How are you going about debugging?

[atomic prairie]

need help! when I press B button in a menu with my gamepad, I go back to my first widget, the star menu, I must have configured this in the past, but impossible to remember where, any ideas to find this key bind and change it?

[maiden wadi]

@little dirge It should not be unstable. It highly depends on what you're doing. If you post your crash log it would be easier to find the issue.

@rugged nexus I don't believe so. That's part of what makes them so efficient. Since they're identical copies, it allows them to drastically improve processing of rendering. If you wanted some with different materials, I think you would need two different HISM components.

@atomic prairie Likely places are either somewhere in the widget you have open, the current player controller for the user, any controlled pawns, the level blueprint, some form of an actor that has had input enabled.

[atomic prairie]

omg i find him..... the input functions..

@solemn parcel You could use a validated get, the will make sure it is not null before executing the functions from that actor.

@round tulip Thanks !

[round tulip]

No problem.

I that error can be quite common with replicated actors.

[solemn parcel]

@round tulip How often should I use the IsValid ? as often as possible or just to fix these kind of errors ?

I saw it being used a lot

[round tulip]

Normally, I only use it when something is not valid. For example, only remove the widget from the screen. when it is valid.

Essentially, I would use it when you are not 100% positive that the reference is valid.

@solemn parcel You can convert any UObject, and any base class or UObject, AActor etc, (the variables with the turquoise blue pin) variable type, into a validated get, which is the same as the is valid macro.

Hey guys, I'm trying to make a car game, I've followed all the tutorial on the documentation but it isnt spawning on the player start, it doesnt posses at all if I place it on the map.

[swift coral]

idk if this fits here, but I cant seem to change the resolution of my widget properly. As you see the screen size is set to my desired 1920x1280, while the canval panel has some different, weird dimensions. When I press play, everything is small and weirdly displaced. How can I solve this?

[errant cradle]

hi guys,
how can i prevent cracking my game from those patches GameName-WindowsNoEditor_p.pak and GameName-WindowsNoEditor_p.sig placed in \Content\Paks folder

[lavish idol]

1. Your Design overlaps at the bottom of the viewport and therefore the lower part will not be displayed.
2. To fix the resolution while runtime, just try to start the game in a new window. Because the editor viewport most likely will not have a 16:9 ratio.

And the better fitting channel would be /UI/UMG

[twilit heath]

@swift coral that custom size there isn't the widgets desired size

its just settings for the preview for the designer

[radiant rapids]

Hi, i have a problem with overlap event. Basically i have made a molotov and as you would expect it leaves a fire on the ground. If the character stands on it for 2 seconds they will start to burn and it does work, my problem is that if the molotov lands next to the player so the collider spawns on the player it doesnt work since it doesnt count as a begin overlap. Any good work arounds?

The overlap event is in the molotov fire blueprint EDIT: fixed!

[swift coral]

And where can I set the widgets size?

[twilit heath]

canvas will go full screen if added to viewport directly

so your widgets inside the canvas aren't laying out properly

use anchors and pivots, never use the coordinate positions for anything other then offset

from the anchor/pivot position

you should set your preview mode to desired on screen there

so you can see what you're doing

[swift coral]

Okay thank you

[round tulip]

Try getting the player controller and start and setting it to posses the pawn.

[round tulip]

It depends on your need, a For loop would work.

[reef mist]

Ill try that next, thanks. But I still have to figure out the spawning thing

[round tulip]

What happens with the spawning?

[weak kindle]

l cant understand it

Why that happens in multiplayer?? where is the false

[gloomy linden]

@swift coral hardcoding resolutions to widgets can be a bad practice as you dont know which resolution the enduser will be using

@weak kindle what do you mean with "where is the false"?

[weak kindle]

@gloomy linden how can l solve this rpoblem

[gloomy linden]

What problem?

[reef mist]

Im using the player start, game mode is set correctly with the vehicle as the default set. But on play it doesnt spawn at all. Collision check is disabled aswell.

[weak kindle]

@gloomy linden l try to create a multiplayer game but when l try run it only first player seems ok others show me that screen

@stray island I've a hard time understanding what you mean with "increase static mesh"

does it need to be even more static?

or mesh harder?

[stray island]

Say for example a pearl

Braclet

And u wanna increase number of pearls

[gloomy linden]

so you want to spawn more static meshes

[stray island]

Choosing how many spheres

Yes

But around a point , so they be circular

[gloomy linden]

drop the static mesh in a blueprint, and spawn a couple of those?

same thing but add cos/sin

[stray island]

I want the option to choose how many

So i dont place them manually

[gloomy linden]

add a widget where you enter a number, put that in that a for loop to spawn the actor that contain the mesh

[stray island]

Sorry i didn’t get the concept

[gloomy linden]

you know what a widget is?

[stray island]

Yes , but that would be a gameplay feature

I dont want it for gameplay

[gloomy linden]

so you want to just code an amount

same concept applies without a widget

[stray island]

I want it for myself to procedurally change

Ya

[gloomy linden]

procedurally?

[stray island]

I didnt get how to do it tho

[gloomy linden]

boy you gonna for a long run

[stray island]

Ignore the word procedurally

But i meant to directly change the number

[gloomy linden]

so you will need the radius of a circle, the size of the paerl to determine how many would fit in that radius, and spawn that amount

[round tulip]

Try placing one in the level and posses it in the Level script.

[reef mist]

Yeah I'll do that

[stray island]

Yes , but its ok if they are overlapped for now

[reef mist]

Hi. I am new here. I would like to make a VR experience to teach a step by step lesson explaining how to use a piece of equipment. I am not a c++ programmer, so am wondering if I could use blueprint to create the simple interactivity this, or at lease the bulk of it. The VR lessons will be fairly linear - the user will learn how to set up the machine. A lesson plays as a video, the machine animates, then a quiz question has to be answered before the next stage of the lesson appears. Does anyone have any examples/advice using blueprint for creating VR training simulators?

[reef mist]

Im not home, i cant try it roght now

[round tulip]

Okay, Sorry, I did not realise.

[round tulip]

This video shows you how to create a simulation in VR. https://youtu.be/n1_h27DWd_o
I assume you would want the Machine to be interactive.

[orchid garden]

is there a simple way like datatables to import the contents for a array to prepopulate it?

[round tulip]

Are you asking if you want to fill a data table from an array?

[orchid garden]

no fill a array from a csv like you can do with datatables

[round tulip]

https://docs.unrealengine.com/en-US/BlueprintAPI/EditorScripting/DataTable/FillDataTablefromCSVFile/index.html

Like this?

Ah, sorry

Mis read you last stement

[orchid garden]

but for a array 😉

[round tulip]

I think you will need to use some C++.

[orchid garden]

i was trying to find a way so i didn't have to manually enter 100 objects to the array

[round tulip]

I can help you create that node.

In a Blueprint Function Library.

[orchid garden]

ah no im trying to keep the project sctrictly blueprint based, no c++

[ocean island]

hmm maybe i would have to recreate the blueprint. I am updating an editor utility widget from 4.25 to 4.26 and the option is not popping up for me.

[orchid garden]

with c++ alot of things would be easier 😉 but doing it soley blueprints makes some things challenging

[faint pasture]

@orchid garden just make a data table, get the row, do something in it and fill the array

[round tulip]

Weird, unfortunately, I do not have 4.26 installed.

[round tulip]

I was thinking that.

[faint pasture]

For each row, get thing, add to array

What are the elements?

[round tulip]

Each row needs to be a Struct, I think.

[faint pasture]

I know

[orchid garden]

how about random selection? with a array its simple as a random int, never tried getting randoms from datatables. the original idea was 8 arrays, each with a single object in each array holder, it would select a random from each array to contruct the final object from all 8 selections.

[faint pasture]

What are the things you need an array of? Ints, classes, references, what?

[orchid garden]

they'd be references to objects

[faint pasture]

Uh

You sure?

[orchid garden]

yep, static mesh objects

[faint pasture]

So you can do it 2 ways.

1. Data table with 1 row of a struct with an array of meshes

2. Data table with many rows of a struct with 1 mesh

Make it by hand, export to json or yaml, edit, import

[orchid garden]

the layout of the datatable wasn't really a question, rather how to select a random from a datatable if i went that route.

[round tulip]

I think the second way sounds, and will be better.

[faint pasture]

Oh easy, get all row names and select a random

[orchid garden]

ah okay so this guy then?

then just random int from the length of the out row names to select the random item

[orchid garden]

i'd still have to make multiple data tables using that cause some of them are 100 items, others are only like 25.

[round tulip]

Then just add each row to an array.

[gusty shuttle]

Is there a cleaner way to GET the level sequence player other than Create

[round tulip]

@orchid garden Would each table be of different type?

[orchid garden]

no the data is all the same just whats in them is different

[round tulip]

Okay.

So just make two tables then.

And two arrays.

[orchid garden]

i.e. basically - get random, set mesh part, get next random, set mesh part, etc. for 8 different tables of various length.

[round tulip]

I would look into composite data tables.

[faint pasture]

Make a table of 8 rows of structs with an array of meshes inside them

[orchid garden]

not sure how a composite datatable would work for my problem.

[round tulip]

Adriel's idea is a good one.

[orchid garden]

a single data table with 8 rows wouldn't work, as some would have objects and others wouldn't.

so i'd end up getting empty returns

[open crypt]

simplest way to get only the odd numbers (basically I want to activate only half of the items in an array) -

[round tulip]

Just do a is valid check then

And perform a different action if it does not have an object.

[proud hull]

Index % 2 == 1

[open crypt]

the module that's what I was looking for, thank you!

[orchid garden]

here, think of it like a character being randomly generated, the head would be 1 list of say maybe 4 objects, the body being a list of maybe 10 objects, the arms being a list of maybe 8 objects, the legts being a list of maybe 5 objects. so each list varies in lenth.

if they were all in one table the list would be 10 objects, while the heads are only 4, so calling for a random head, the possibility of hitting a invalid would be high alot.

[round tulip]

What about a map(dictionary)?

What you could do, to help, is make the struct type and send a screenshot.

Can you not use random int in range and get the max size of each array to pick one of the options from each array?

[orchid garden]

so basically build a array of each row in the data table, then select from those arrays?

[dawn gazelle]

yeah why not? 😛

[round tulip]

That's not a bad Idea.

[dawn gazelle]

or at the least, just the names, then grab the actual data when needed

save some memory or something

[orchid garden]

it'd be called per actor of that type so.. yeah would probably want to make it a global function call that could be interfaced..

[round tulip]

What about a macro library which returns that data? This macro would only be defined for a certain type of actor

[orchid garden]

macro and function libraries can't store data, and doing multiple fuction/macro library calls to contruct could cause memory usage explosions.

[round tulip]

Just store the data in the parent actor.

And clean the array when necessary.

[orchid garden]

where as storing the data in a gobal object (like game instance) i'd only have to construct it once and use a interface call to get the random parts for the actors of that type

[round tulip]

Yeah.

[orchid garden]

seems like this would be a better option then per actor, expecially if there were like 50 of them loading in

thanks for the suggestions 🙂 @round tulip @dawn gazelle @faint pasture most helpful 🙂

[round tulip]

@orchid garden What about a simple blueprint function library function like this?

So you do not have to keep performing lots of casts.

[open crypt]

nothing super expensive about using event tick with a delay to toggle a light on and off right? (like strobe)

[proud hull]

@orchid garden one more route you can take on this, which I use for displaying key/button images (would have been super tedious to manually make a table or array since there were so many images). You can load the uasset directly (using Asset Registry) based on naming conventions and/or folder structure. Take your character example, you could store all heads in a "Head" folder, all arms in a "Arms" folder, and these folders in a "BodyParts" folder. Then you can also use naming conventions to get even more specific, like certain heads could be for different species or something, "human_1", "human_2", "alien_1", etc. You just need to remember to include this main folder when packaging.

[round tulip]

What about a timer?

You could use tick, but timers are slightly better for performance, I think.

[faint pasture]

Don't need tick at all. Use a timer or loop with delay and random delay lengths.

[proud hull]

You want to avoid putting delay nodes on event tick.

[fair magnet]

Hi there.. complicated but simple question.. I have a Event which sets a timer...
I want this even to be set twice if I call it twice...
So If i press E twice which calls said event it actually sets 2 timers instead of one

is that possible ?

[storm dove]

what the inputs should be for this node? im trying to check if the player is looking at an object?

one of the inputs is players forward vector right? whats the other one?

[fair magnet]

@storm dove https://www.youtube.com/watch?v=7zE_YA4z87M

[storm dove]

this does not explain it

[dreamy ice]

Why aren't you just doing a line tracE?

[faint pasture]

What is it connected to? We can't see

[maiden wadi]

@storm dove Dot product is the comparison of two directional vectors. So comparing if one actor is looking at another, you'd want the player's forward vector and then the unitdirection from the player to the object.

[open crypt]

why?

[storm dove]

thank you @maiden wadi

[open crypt]

doesn't that just make it do that same action less, so if you are going to tick, at least use a delay to save

[proud hull]

It can create problems with the overall timing of the main loop.

[faint pasture]

Because it's fucky. Idk how it'd even work, instance a delay every frame?

[open crypt]

My understand was if you some action, it would check every frame to do that action, but wouldn't actually proceed with the action and any calculations unless it met the delay material

and since that's a simple float check, that shouldn't be expensive but I take your meaning

[faint pasture]

That's pretty much what a timer or a single delay does.

[proud hull]

If you want to delay your tick, just change your tick interval rate instead.

[odd ember]

dot return 1 if two normalized vectors are the same, -1 if they are opposite and otherwise somewhere on that scale

[faint pasture]

Specifically, if both vectors are length 1, dot product will be 1 when aligned, 0 when perpendicular, and -1 when opposite

[odd ember]

if you're using it with unnormalized vectors you're gonna get weird results

[solemn parcel]

So i've got my MAX AMMO showing with this, but how can I add a '/' just before the number, without creating a new text widget component ?

[storm dove]

thank you

[dawn gazelle]

Every frame the delay will be called, and the stuff after it will happen after the delay. So if you wanted a 1 second delay (approximately 60 frames), you could have 60 things waiting around to execute, and every frame afterwards it would execute, meaning you're still firing things every frame.

If you use a timer and set it to fire once a second, you don't have anything waiting around to execute, and it'll only fire once every second.

[open crypt]

I'll use that for sure (I have in the past) I guess conceptually, I'm not understanding - how does the timer itself not using some form of check, it has to increment, and something has to check to make sure it isn't expired - I guess it's just hard coded in the assembly and more performant that way

[fair magnet]

Anyone ? :o

[odd ember]

it isn't possible in blueprint, no

[solemn parcel]

@proud hull Thanks !

[odd ember]

or well, you can do it but you have no way to turn off timers individually

so eventually it's going to lead to a memory leak

[dawn gazelle]

You could check to see if the first timer is valid and if so, create a second one.

[fair magnet]

@dawn gazelle I thougt about this but I would need alot of timers then

[faint pasture]

What exactly are you trying to do?

[odd ember]

yeah this sounds like a hacky setup

[fair magnet]

Manipulating Variables for some duration... but I want things to stack so like...
If I call that event once it reduce health for example by 20 for 10 seconds and gives it back after
but If I call it again during that period of time it will reduce by 20 again by 10 seconds aswell

kind of hard to explain

[odd ember]

so two DoTs stacked of the same type

[fair magnet]

exactly

[faint pasture]

@fair magnet use GAS or structs with a system to run them

[odd ember]

you could create a scalar value

[faint pasture]

Or just actors

[odd ember]

on a single timer

but that's just going to approximate that effect

but yeah something that exists in the world is the better choice here

actors or perhaps even a component spawn

[fair magnet]

@faint pasture What exactly is GAS ?

[dawn gazelle]

Do you want the DoTs of the same type to tick separately? ie. Lets say you have a "poison" effect and the effect can stack. Do you want each stack to tick independently?

[faint pasture]

Or a struct in a BuffComponent

[dawn gazelle]

Gameplay Ability System

[odd ember]

I'd say components are your best option

[dawn gazelle]

requires some C++ work if you want to use it.

[faint pasture]

@fair magnet is your game multiplayer? Is it fast paced?

[fair magnet]

I have no experience with that system at all

[odd ember]

it's the cleanest in BP, for sure

[faint pasture]

@odd ember is adding components at runtime a performance consideration?

Like are you talking about the buff being a component or the buff being data inside a component?

[fair magnet]

@faint pasture it is multiplayer but don't know how fast just yet

Rn I'm just setting up logic

[faint pasture]

@fair magnet I would just start with buffs as actors. Then you can attach them in the scene and they can have their own little particle effects and sound etc, and manage their own lifetimes

[proud hull]

@faint pasture components are simply just data storage anyways. They can be as small as holding a single variable or as robust as the movement component.

[faint pasture]

I mean adding/removing often at runtime, sorta like how an ECS uses components.

[proud hull]

Creating your own custom components allows you to keep things modular and clean.

[fair magnet]

So should I use Components or actors now ? o.o I'm confused lol

[faint pasture]

@fair magnet start with making a buff actor.

If you're fairly new to unreal it'll be the easiest and most intuitive way to do it.

[fair magnet]

I guess I'm semi-new :o

[faint pasture]

You just make an actor with like an affected character variable, and a couple of events for on apply, on update, on remove, etc.

Then to make a DOT, you would do damage to affected character on update

Update being on a timer prolly

[fair magnet]

I think I've got a plan...
Making an actor with a lifespan of the buffs duration.
Creating a Datatable for various buffs
Setting a row on a skill or smth and just assing all the information through to the actor so the actor can apply it properly

[faint pasture]

It won't be super elegent for something like stacking slows but it'll work.

[odd ember]

components would be better since you will be adding them to actors

adding actors to actors will be a pain

[fair magnet]

Maybe I can make an array to check if a buff is already applied and if so do things

[odd ember]

tbh it's the most elegant you'll get in BP

everything is perfectly decoupled

[fair magnet]

Arrays are Op ngl... I love them :o

My whole attribute system is built around them

[faint pasture]

@odd ember are you talking about buffs as components or buffs as data within a buff component? Like when you apply a dot, are you adding a component to the character or are you adding a struct to the characters buff component?

[odd ember]

you should be using structs for that I reckon

[odd ember]

both. a debuff is still a buff

[faint pasture]

I mean if you have five bucks, do you have five buff components or do you have one component with five buff structs within it? That's what I'm asking.

[odd ember]

for stacking you will need multiples

in BP

[willow phoenix]

instead of this 800x600 texture setting the scene capture gets rendered 1:1 (but i want to use it as a picture in a frame with a 8x6 ratio)

any ideas on how to solve this?

[odd ember]

you're never going to get around that, because stacking in code terms is undesirable repetition

[willow phoenix]

1:1 ratio ._.

stretching the mesh works but looks like a shitty streched image

[faint pasture]

@fair magnet if you have a deep attribute system, and you're okay with c++, look into GAS. It's super robust but a royal PITA to get started with.

[fair magnet]

Well I have legit not a single clue about cpp o.o' don't even know how to create variables in there lmao

[faint pasture]

@fair magnet k then NVM lol

If you need your system to be deep and robust, you are going to want to make a component that holds attributes and effects and handles and applies them

[orchid garden]

wouldn't you just modify the uv's on the mesh to get the 8x6 ratio for the picture frame? (requires editing the mesh)

[fair magnet]

I have smth like this as of now

[odd ember]

the problem with data tables etc. is that they don't describe logic

just data

[fair magnet]

yea :o can't I do this in here as well ?

[odd ember]

you can but you ideally want to settle on a class that manages what type of logic your effects can have

[solemn parcel]

@Is there a way to interrupt a PlayMontage ?

[willow phoenix]

mehhh, i thought there would be some thing im missing. thanks

[odd ember]

so if DoT is one of them, then that should be described as a type in the data that the effects manager can then use for instance

[orchid garden]

are you just trying to get it to tile to 8x6 on a large surface? if thats the case you should be able to do that modifying the texture uv's in the material file itself.

[willow phoenix]

ye did that, thought i could just add some magic hook anywhere to do it "the correct" way

[proud hull]

Stop the montage. Can also pause it and adjust its position, not shown in screenshot.

[solemn parcel]

@proud hull Thanks again 😉

[orchid garden]

another way would be using a widget object that locks the scale of the texture in the widget itself, so no matter what its scaled to, the image will always show in scale on the object, that can be tricky though.

[fair magnet]

@odd ember Enumerations ?

[odd ember]

can be any type of tagging

[round tulip]

Actor tags?

[odd ember]

could also be an array of tags for instance if you're looking for multiple effects to happen within one thing. but then you'll have to figure out if they happen at the same time, delayed etc. and how to ensure you can dictate and write that logic

[fair magnet]

I'll probably go with Enums... that way I can easily add later on

[round tulip]

Or gameplay tags

[odd ember]

I've personally just bundled a specific class in the data table that houses the logic because I often use custom logic, but I'm not sure I can recommend the same for others

[fair magnet]

like creating an actor for each type ?

and then defining the type in the data table ?

[odd ember]

like I said I can't really recommend it

[willow phoenix]

just created a mesh in UE and set the UV to 0.8 and 0.6

worked, since im not even close to a single A game idgas ;D

[sturdy notch]

Not sure if this is the right section, but I need a hand with object outlining beyond what my post-process material can handle.

[open crypt]

wtf am I doing wrong with this - I'm trying to get my Pawn to spawn to this DebugCameras position (so it takes the same view)

[winged pewter]

If you're looking for something quick and dirty, this method has been very useful for me. It's not exactly scalable or maintainable though...
https://www.youtube.com/watch?v=1XqXvVFN5i4

^ @sturdy notch

[odd ember]

probably #graphics is a better place to ask

[open crypt]

What is wrong with this BP? It spawns in the previous orientation of my other pawn

[sturdy notch]

Thanks @winged pewter - the issue isn't not having a way to do it, it's that I can't set a custom render depth to anything not already a component of an existing blueprint - only the existing static or skeletal meshes. @odd ember I'll try in graphics. Thanks.

[hollow drift]

ok.....

[gusty shuttle]

I'm trying to update my widget via Event Dispatchers. However when I construct my widget, scan the world for my quest actor (which is definatly in the world at this point) it says it's not valid and my widget does not populate, any tips?

I call them on Begin Play of my quest once it spawns too

Any tips?

[winged pewter]

not much is in the world before the construct step - how are you sure it's there?

[gusty shuttle]

I can flick it on and off (the widget thats attach to my VR wrist)

And it spawns and destroys

So it should read fresh every time it spawns

[odd ember]

race conditions

[gusty shuttle]

So if I can visibly see my quest actors in the world, and I open my wrist widget, still not populating

[odd ember]

why doesnt your quest actor spawn the quest UI

[winged pewter]

^ that's what i would recommend setting it up like, but if you want to keep them detached, i'd figure out a way to set a reference to your actors in your widget without using the GetActorOfClass

it's kind of slow/unsafe to use that during gameplay...

[gusty shuttle]

Even on construct, and there is only one in the level. It's not on a tick

Right now, my quest actor, spawns the quest UI info. So I can just create a child actor for the quest with all the loc, rot, objective blah blah in it

[odd ember]

oof child actors

[gusty shuttle]

Still though, I'd like to know why that's not showing as valid even when it's clearly in the level

[winged pewter]

how are you spawning the quest actors? did you place them in editor or spawn them programatically?

[quiet token]

Guys i'm askin for 3 days for help on this i know, but is maybe someone online right know what knows how the counterstrike/quake strafejump mechanic works? I just dont get it.

[gusty shuttle]

Well I'm truing something new @winged pewter , I am spawning the quest actor in via level sequencer

[odd ember]

I thought you didn't have time to implement it?

[gusty shuttle]

I have done it programerly wise before, worked decent and well. Just trying something new

[winged pewter]

level blueprint? or are you actually using sequencer?

[gusty shuttle]

Using quest events

In sequencer

[quiet token]

@odd ember nothin workin so far, i want it xD but actually no one understands what i mean, i need to call someone that has knowledge and show him quick. its really more complicated then ppl think

[gusty shuttle]

Via SequenceDirector

[odd ember]

you had the math from that one article

it's all described there

[quiet token]

@odd ember i think its just the bunnyhop part, not the strafejump itself wich i'm intrerested in. And even if its there on paper, i could use a hand cuz i can't translate that into my bp editor ^^ I can understand if u dont wanna be that person, but i hope someone might be interested sooner or later 😄

but i'm learnin day in and out, maybe in a week i can get it myself

[rough blade]

When it comes to representing players in vehicles (driver sitting in the driver's seat for a jeep for example), is it better to have a skeletal mesh to just mimic the players model or would you suggest having the player pawn lock itself to that relative location (while playing anim) via a tick function?

[stray island]

Soo my attempts has failed

I’m trying to rotate meshes around a point

https://youtu.be/hc3WF3vrc38

With a choosen number

[faint pasture]

@stray island mesh angle = Index x 360/NumberOfMeshes

MeshPosition = Center + Rotate vector((Distance, 0, 0), Z, Meshangle)

[odd ember]

is this in blueprint?

because you're showing a blender video

[stray island]

Yes i want to do that blender duplication in unreal blueprint

[stray island]

Oh , i will try that i spent hours and failed , is it this simple 😇

[odd ember]

ah I see

you could also parent the mesh to a point that you spawn and rotate said point

and for each new mesh, just do the same

[faint pasture]

That's about the Z axis, for arbitrary rotation axis and start direction it'll be a little bit more involved but not too bad.

Or just have a root component above the mesh component, spawn them all in the same place with different rotations, and offset the mesh locally on all of them

[stray island]

I will slowly understand the logic

But what i want is to expose and instance the number of duplicates so in editor if i type 100 it would have 100 meshes around a point

Will this logic lead me to that?

[faint pasture]

Do it in the construction script and add all the meshes there.

Also use instanced static meshes if you're gonna have thousands of the suckers.

[stray island]

Yes i will do it in construction script

Its one mesh to add , the number determine its dublicates around a point

[open crypt]

This prints out values as I move the mouse, but does not move

so I know I have input, but why is my pawn locked ?

[odd ember]

paused?

[open crypt]

nope, because i can move around other movements

[odd ember]

breakpoint it and trace down the origin

[simple sky]

Does anyone know where the editor saves keyboard binds to? I'm trying to test rebinding keys and I'd like to "reset" the changes; but I can't find anywhere it's stored

[dawn gazelle]

https://blueprintue.com/blueprint/um3xiqc5/

[odd ember]

yeah that's how I would have done it

tbh I'm low key waiting for blutilities to get more features. it's a great system but it is very limited right now

[dense isle]

Can I change any of these values at runtime for a Capsule Component?

I basically want to enable or disable something as a Dynamic NavArea_Null component, because it falls from the sky for 5 seconds. I only want it to became a NavArea_Null once it is on the ground

[hollow drift]

hi folks. i struggle with BP interfaces again. I want to tell another bp that an action has been done in the playercontroler

[odd ember]

use delegates?

[hollow drift]

and it should do stuff

@odd ember can you please elaborate what do you mean with this?

[odd ember]

event dispatchers sorry

[hollow drift]

@odd ember ty 🙂

[pine trellis]

if I have no nav mesh on my level, am I suppose to see a nev mesh if I hit the P key? Because I removed my nav mesh and try to add a new one but its like its taking up the whole map,, but its small little box right now

[odd ember]

if you have no nav mesh then no nav mesh will show up

it goes without saying that the nav volume dictates the size of the navmesh at its largest

[pine trellis]

yeah but If I remove everything, my nav mesh still shows up if I hit P on the keyboard

[odd ember]

is your navmesh static?

because usually the navmesh is baked

you'll have to rebuild paths if you removed it

[pine trellis]

how do I rebuild without a nav mesh?

[odd ember]

the same way you rebuild with a navmesh?

build options > build paths

[pine trellis]

cool thanks didnt know if it was bugging out

[hollow drift]

leme rephrase my question. I think i went on a wrong approach

the bp i tried to make a call to is an actor. what kind of bp can i use to execute something which is not part of the playercontrole. issue is i try to split my code in more parts. therefore i try to move code out of my playercontroler.

[odd ember]

I think more context is necessary

[hollow drift]

Actors are only present when spawned in the level

therefore i cannot put code into actor without spawning it

[odd ember]

that is correct

[hollow drift]

my goal ist to separate code from my playercontroler

[odd ember]

well I don't know what code it is

so I can't tell you what to do with it

[hollow drift]

the playercontroler picks up a pawn and moves it around the map. the code i try to separate is calculating according to pawns location valid tiles

so i am passing following details

[odd ember]

so what's the issue you're having

[hollow drift]

first i do a ref to the actor i am try to pass to. but thats what i am trying to replace
all other values are as shown above

[odd ember]

in more concise terms

[hollow drift]

what type of bp can i use which does not need to be spawned in the world but where i can put code aside?

e.g. i can acces all time

ecxept for gamestatebase

or i just create a second gamebase?

hmm, perhaps went full circle

gamestate...?

[odd ember]

what is the issue you are having? that your pawn isn't spawned when you want the pawn to do something?

[hollow drift]

our main issues is that we work with github/gitlab and those cannot read binaries. Because of that only one person can work on one file at a time

therefore we try to separate the code into smaller pieces so people can work more or less on one "game element" at a time e.g. playercontroler

[odd ember]

that shouldn't affect architecture. but to be honest it does sound you have a problem with your current architecture anyway. but I can't give you a suggestion because I still don't know what is being dealt with. I see you're giving input to pawn from controller

[hollow drift]

and therefore i try to separate code. pass values from one bp to another ectr

[odd ember]

this is usually how it's done

[fading raptor]

Does anyone know how to use a lerp node?

I made my character change his angle based on his velocity which works great, only problem is when my character hits the ground it snaps to the rotation

how do i make a smooth transition?

hold on im trying to send a vid

[odd ember]

rinterpTo

[fading raptor]

Where should I put the node?

[hollow drift]

how can two blueprints interact with each other?

[fading raptor]

Make a child blueprint

[odd ember]

this is a really bad idea to do with the character movement. you should handle it in animation

[faint pasture]

https://youtu.be/EM_HYqQdToE

[fading raptor]

I tried doing that but realized that im not sure how i would make it work when my player falls longer distances

[odd ember]

animations can be looped

[fading raptor]

Yeah I know but like how would I loop the angle at which the player falls

Wouldnt the loop just snap back to the starting angle

[odd ember]

not sure what you are referring to

[fading raptor]

I sent the fox video above, im referring to how the fox rotates when it jumps

[odd ember]

I mean you separate it out into a start jump, mid jump, end jump animation

loop the mid jump for as long as you need

[fading raptor]

Thats what I did in my anim BP

I basically recreated the third person template's aniim bp

[odd ember]

cool so what's the issue

[stray island]

@dawn gazelle wow thank u so much cant believe its that simple

[fading raptor]

My character's rotation snaps when it hits the ground

[stray island]

I actually spent two hours trying to combine these two tutorials

https://youtu.be/64Q80zS88aY

https://youtu.be/pWuVc3aBBCo

[fading raptor]

I tried using the rinterp but im not sure im doing it right

[odd ember]

fix your end jump animation to take care of it

and perhaps consider getting some IK to work, though that's another massive can of worms

I wouldn't recommend doing anything with the character capsule for this

just handle all of it as animation

[fading raptor]

fixing the jump end animation would solve part of it

But with the animations im clueless on how to make it work

[odd ember]

if the animation plays as the character lands that's pretty much what you want

[fading raptor]

Yeah ur right, however im also getting another problem when i jump without moving, hold on let me record it

[odd ember]

then you probably want to consider blending that into the movement animation if they are moving instead of standing still

but these are all #animation considerations

[fading raptor]

once i start working on the animations ill head on over there, i just need to figure out this one problem gimme a sec

as long as i can figure out how to smooth the rotation, ill be set

[odd ember]

that's my point

you are going about it wrong

fixing the rotation isn't what you need to do

you need to handle it all as animation

that will make your issues disappear

no rotation necessary

[fading raptor]

So i make my character rotate in my jumploop animation itsself?

[odd ember]

yeah that's kind of the point right?

[fading raptor]

lemme try explaining my confusing in a drawing

[odd ember]

to not touch the physical constraints of the capsule without reason

especially not for animation

[fading raptor]

nvm i cant draw

Well if i want to loop it wouldnt it just keep looping the same rotation over and over until i land?

[late blaze]

Can someone help me getting the same number which was sent to the Set Scalar Parameter Value on Materials to the Set Custom Depth Stencil Value to be equal?

[odd ember]

no rotation. handle it in animation

[fading raptor]

aaahhhhh

Either im dumb or im not understanding

[dawn gazelle]

Promote the random value to a variable, then use that variable on both nodes.

[odd ember]

you will handle the rotation as a visual effect as part of the animation

[fading raptor]

yeah thats what i mean

[odd ember]

but your capsule does not in fact ever rotate

[fading raptor]

oh

Is there a tutorial anywhere that could guide me in the right direction of how i should do that, cuz i have no clue

[odd ember]

you just make your animations

and do it as part of those

that's it

[fading raptor]

oh shoot i think i know how to do it

[late blaze]

Like this?

[dawn gazelle]

Yep

[fading raptor]

I could just make the animation and put it into the jumploop but instead of looping it, it just plays once and stays at the end position until i land

[odd ember]

yes

[dawn gazelle]

The reason that happens is that pins always calculate backwards - so if you have two things pinned into one node, they'll both call whatever function they are attached to, and in the case of a random number function, they get different results.

[open crypt]

I want an light to strobe, but I also want it to rotate - I'm using a timer but realized I need different times to do this things in

otherwise the movement is very jerky

[odd ember]

#released

[open crypt]

I'm trying to do it with timeline but I'm not sure how to loop back around to 360, right now it turns around instead the other way

[odd ember]

so you want to reverse the timeline instead of looping it?

[open crypt]

yeah but I have it started at begin play, I can't link it to the timer

[odd ember]

you shouldn't use a timeline with a timer

use either, not both

[open crypt]

no, i'm handling the rotation on its own, this way

and the timer handles the toggling of the lights

[odd ember]

you can plug both into the timeline

[open crypt]

you are right too, but the rate would be different

which I guess is the point of a timeline

[odd ember]

you can have more than one track

each track is handled separately

[open crypt]

I know that but how do I get this to keep going around

[odd ember]

but they run over the same period

there is an option to loop timelines

[open crypt]

it loops fine

but it goes back the other way, because it's 360

i've tried with 180, and 360

not sure what i am suposed to put for the end, or maybe just leave it at the high point

[odd ember]

make it go 360 instead?

instead of 180

you can leave it at that

since 360 == 0

[orchid garden]

set the timeline to go from 0-359 for the value to avoid a pause.

[open crypt]

thanks, got it, knew I was on the right track, thanks for helping me get over it

i was just about to ask

[orchid garden]

360=0, so you'd have 2 returned values of 0

[open crypt]

that pause is still there, perhaps just an angle of my perspective?

[odd ember]

no I see it as well

[open crypt]

weird - what am I doing wrong here? should I be adding or setting rotation - adding right?

[orchid garden]

set should make it smooth

[open crypt]

I still see that hickup, standby I'll show values of timeline

[odd ember]

sharpen the curves or make them linear

[open crypt]

jmust be the tangents of the curve maybe?

[orchid garden]

use linear not curve for the points

[open crypt]

ah thaks

*thanks

[lime fulcrum]

Is Noise Maker component calculating the audio occlusion for example when using Steam Audio?

[odd ember]

probably better to ask that with people in #audio

[lime fulcrum]

Roger that 😄

[fading raptor]

How do i get my actors current rotation? I tried dragging out of character movement but its not working 😦

nvm

im dumb

[hollow drift]

quick question. If a Actor is set to hidden, does its collision component still generate hit results which, for example still can be read with a cast?

[odd ember]

hidden is just visibility it has no effect on collision

[hollow drift]

kk ty

[olive sedge]

I'm trying to ragdoll a character but it falls through the floor, any tips?

I have collision enabled for both

I'm trying to animate a material so it translates the UV coordinates over time, but nothing is happening when I do this - the texture just stretches itself so that bands of color appear instead, no matter how I change the constants (I'm adding this to the texture UVs):

I'm aware I could also make one of these variables a parameter and change it in the level blueprint, but I'm curious as to why this doesn't work

[odd ember]

#graphics, materials and blueprints aren't the same

[night quail]

Oh boy. Thanks for that lol still getting to know the terms

[finite osprey]

Hello i have i quick question. Im currently working on weapon switch and i handle it thru spawn/destroy actor from class. all their values are reset to default after switch(like ammo) what is the efficient way of keeping their values? In playerBP? DataTable? Should i use object reference instead?

[odd ember]

probably better to use object references instead yeah

[still plume]

Hello. Is cast to... A good way to enter in a actor to take and set information? Is better if I use any time a interface or other solution and not cast? Or I can cast any time withouth problem?

[quiet token]

Can someone explain to me why i'm not just addin force towards where i'm lookin? He's always pushin me to one coordinate on the world it seems

[dawn gazelle]

You shouldn't need to add the current location.

ie. You don't need to add GetActorLocation to the forward vector calculation.

[quiet token]

ahh thanks, i had the same thing yesterday >_< I need to learn that the vector already has a reference to where i am ^^ I always think i need to tell him that

[dawn gazelle]

Get Forward Vector has no idea where you are. It returns only which way you are facing.

If you're looking to apply force in a specific direction, all you need to know is the direction to apply the force, not where you are.

[quiet token]

ok thanks!!

[odd ember]

casting is fine. if you're worried about costs use the profiler

[lean reef]

Thanks Mirrors Edge, nice video. Do you know any examples of using blueprint to make a simple multiple choice quiz?

[ornate terrace]

Hey, so i've been wondering about how to make Sprinting Camera Shake, i tried it, it worked but only on singleplayer project, on multiplayer the camerashake persists even after Stop Camera Shake action, any ideas?

[solemn parcel]

AFter putting a branch, i'm having this whenever the player as health less than 0 and is being destroyed.

having this without the branch

Im a little lost on this

[trim matrix]

Isn't the branch condition reversed? Shouldn't it be < ?

[dawn gazelle]

I'm guessing you have a text widget bound to your player health value. It probably shouldn't be a direct bind, rather, when your health changes it updates a variable in the widget.

[solemn parcel]

a progress bar bound to health

a text bar bound to ammo

[dawn gazelle]

and since your player is dying and being destroyed, those values go invalid.

[solemn parcel]

oh

so creating a new variable on the widget for health ?

that takes the sames values as the CharacterBP as health ?

[dawn gazelle]

Yeah, whenever you're changing your player's health value, you should be setting the value in the widget.

[solemn parcel]

mmmh gonna check that

thanks

[stray island]

datura i have some questions regarding the rotate meshes around point

@dawn gazelle remember?

First question how do i increase the distance each time a new duplicate added , so instead of forming a circle the meshes would swirl instead

[dawn gazelle]

Distance = Number of Meshes * Your own deciding size factor

[autumn hawk]

Any tips on how I might go about allowing Editor manipulation of actor components using gizmos? I have an actor with a collision component and a box collision as children, and I'd like to be able to resize/move the boxes using gizmos in the editor as opposed to numerical changes in the details panel.

[stray island]

They didnt do swirl effect

They still circualr

Circular

[dawn gazelle]

I do not understand what you mean by swirl. If you do this, and set distance to 25, then each time you add another mesh, the circle will grow bigger. If you wan the meshes closer together, set distance lower, if you want them more spread out, set bigger.

[odd ember]

he's asking for an offset per mesh that increases exponentially

[acoustic hamlet]

^make a timeline for that then

[odd ember]

this isn't runtime I'm pretty sure

[acoustic hamlet]

oh well then idk what they're trying to accomplish

if its not runtime why does it matter if it increases exponentially

?

[odd ember]

anyway the idea is something like distance * (meshNumber/totalMeshCount)

if it's a blutility thing then it matters just as much

[dawn gazelle]

Mebbe he means something like this?

[odd ember]

yes

[stray island]

I want the distance to increase an “X” unit each time a duplicate added for example first cube is 10 units away from point , second is 15 units away ... etc so it wont be a circle anymore

YES

That screenshot , how did u do it

[dawn gazelle]

Windows Key + Shift + S

[odd ember]

lol

[stray island]

I mean its content

[dawn gazelle]

In the engine <_<

[stray island]

Yes

[odd ember]

a magician never reveals his tricks etc.

[dawn gazelle]

Slightly modified the loop and...

The index of the loop feeds into this

I am a very literal person XD

[stray island]

That looks awesome but tbh its missing a tiny bit to be

My target

I want the same exact circular shape , with the choosen distance from center point as we did firstly

Then starting from that distance , rest cubes grow

Not starting from 0,0,0

[odd ember]

ah yes, that distance

that distance we're all familiar with

[stray island]

Yes the “X” distance

First cube isnt at center but at distance from center

[odd ember]

so... add that distance?

[stray island]

How

The swirl trick changed the logic of the circle

[quiet token]

WOOOH i almost got what i wanted to archieve, in a slight different variation. When i Jump now he's always flyin to where my mouse is lookin so the player can jump in a curve. But i know that i cant use that feature like this. is there any way i could implement this into my jump? Cuz when i jump now i'm Floating with the effect i wanna have, but its not the actuall jump velocity etc.

[odd ember]

there is no possible way for you to attempt to merge them

[stray island]

I will try to merge them

I have another question, if i want to add another row of these dubllicates , what do i do , array?

[odd ember]

try

tbh I'm so far removed from this implementation I have no idea

[odd ember]

not sure what you mean here

what do you want?

[quiet token]

ok wait

i try to make it clear this time ^^

dude can i call u for a sec and stream this shit?

[odd ember]

sorry, not open for that kind of business

[quiet token]

kk then i try to explain here

I want that the player flies always into the direction he's facing after he jumped, always following the crosshair so to say. With the nodes i posted i emulate what i want, but when i constantly add the velocity to the player like this, he's floating forever. So i added the Up Vector with a - value so he comes down to the ground over time. But ofc this istn the same as jumping.

[odd ember]

I see

so you're asking if you could modify your jump to do this

[quiet token]

i want to add velocity but in concideration of the players normal jump

yeah

after he jumps the mouse should lead the direction

cuz he has 0,1 air control

like in counterstrike

[odd ember]

you can still have air control

[quiet token]

i dont want him to

[odd ember]

well then just remove it in the character movement

[quiet token]

when he jumps and then press left, nothin happens, he has to strafejump

ok u dont get it ^^

maybe i explain too bad

[odd ember]

air control doesn't care if you're "jumping" or just in the air

[dapper hearth]

A game of keep away how would one go about doing a node for that? I’m sure I’ll figure it out if not

[odd ember]

so if you set air control to 0 then it'll not have air control regardless of how you are in the air

[quiet token]

the air control has nothin to do with it, all i wanted to say is, that in my game i dont allow the player to have air controll, other then via strafejumping

[odd ember]

so set air control to 0

[orchid garden]

hrm... so i did a 'set actor location and position' using a refrence to my main character... and rather then it setting the actor to the x z of the position, the character was positioned so that the camera was at the x z of the postion, is there a way around this so that the actor is actually moved to the postion and not based off what camera the player is using?

[quiet token]

i did

but

when i jump

with this

im floating

^^

i want the player to jump up and down as usual with a normal jump, but mid air he can control with mouse

[orchid garden]

to show what im talking about, the character isn't centered with the chair, rather the camera is (represented by the white dot):

[quiet token]

and it happens to be that this velocity thing wich i made has exactly that mouse feelin, but its no jump ^^ i hope that makes it clearer

[odd ember]

try to split the forward vector to use use x,y and leave z blank, and try without the upvector

see if that changes anything

[quiet token]

kk

nope

[odd ember]

so what happens

[quiet token]

i still float until the up vector with -200 gets me on ground eventually

[odd ember]

well I did say remove the up vector

[quiet token]

ah sry

endless float

[odd ember]

yeah okay

I get why

so do this

[quiet token]

ah and i added a delay 0,2 before can strafe is active

otherwise i coulnd even jump cuz he starts as soon as i jump with the floating

[odd ember]

character movement > get velocity

split that

[odd ember]

take the z

and put it into your set velocity

[quiet token]

ok wow so much info

mom ^^

[odd ember]

the x,y use from your forward

the reason you're not falling down is that your forward vector is overriding your velocity

and your forward vector will have 0 in z

so

[quiet token]

wait, i try this and then i try geekys function

@orchid garden thanks alot!

[odd ember]

using the previous velocity's z will use gravity

[quiet token]

@odd ember kk mom i try

[orchid garden]

@quiet token its what i use for a second jump when jumping.

so anyone know how i can get it to place the actor in the center x z location instead of the camera?

[quiet token]

Like this? cuz its buggy

[odd ember]

try just setting it directly

instead of adding

[quiet token]

wich one? only the z?

[odd ember]

both

use a new make vector

[orchid garden]

some reason its not placing the actor properly...

[odd ember]

instead of the add node

[quiet token]

Yoooooo, thanks i think thats it!! Now i have the issue that he's jumpin forward even if i'm just pressin jump and i cant jump backward etc. but i think i'll figure that out

this was what u ment right?

[odd ember]

https://blueprintue.com/blueprint/rjs_r027/

you can try with that or with last update velocity as I gave you

[quiet token]

just copy paste or what?

[odd ember]

try yours first

see if it works

ah yeah I see

so in order to fix that

you will have to go into your character

[quiet token]

i did yours now, its the same but more clear

[odd ember]

in your character forward movement

[quiet token]

dude thanks for helping me

ye

[odd ember]

event

move forward or whatever it's called

do you have such a node?

[quiet token]

this is my movement

u mean forward axis there yeah

backward_forward

[odd ember]

alright yeah perfect

so

[zealous moth]

did most actors come with a self-destruct timer property or is it through another component? i forget

[odd ember]

lifespan

@zealous moth

[zealous moth]

ah perfect, ty

i was looking at time or duration

[odd ember]

take the axis value from either

and make them into a variable

that is set every time you use that event

does that make sense?

actually do it for forward first

[quiet token]

hoops, i need to connect

i do just before the branch on the lower one

[odd ember]

yep

the very first thing

on both

[quiet token]

done

[odd ember]

now that you have that axis value, go back to your previous logic

[quiet token]

aye

[odd ember]

in your previous logic, get your axis value for forward backward

and plug it in like I did this literal node https://blueprintue.com/blueprint/j7vldga6/

[quiet token]

u mean like this? its not workin well

[odd ember]

ok what's happening

[quiet token]

he jumps a little in a direction and after 0,2 sec or somethin like this only upwards

stops in every other direction

only z momentum

[odd ember]

so remove the delay you have before your jump

and try to jump and move forward

[quiet token]

if i jump now and then press forward nothin happens, only jump. if i run forward and then press jump its the same, only upward motion

[odd ember]

so can you check your inputs in your project settings and tell me what the axis values are for your forward backward movement?

[odd ember]

strange

so it should work

basically the idea is that your axis is a scale value that sits at 0 while standing still

but changed to 1 or -1 if you move

[quiet token]

maybe cuz of this`?

cuz i set the velo there too?

[odd ember]

could be

[quiet token]

the player can get a little boost when he jumps 0,1 after landing

i plug it out

for a moment and check

[odd ember]

also you can just use the GetForwardBackward node that you showed in the jump section

I forgot that input axes have their own nodes

[quiet token]

nope, no change

with the other forward backward its the same, but that makes sense i guess

mhhh

[vestal plinth]

if I have a class MyParent and it has an inherited class named MyChild, and then I create a variable of MyParent type and assign a MyChild to it, if I call GetClass on it, what will I get back?

[odd ember]

debug the value of forward backwards. seems right now that it stays 0 when it shouldnt

[quiet token]

when i jump and press forward its 1, when i press backward its -1

[odd ember]

so it's correct then

debug the code for the strafe and see what value it shows

[quiet token]

wich one?

[odd ember]

on tick

[quiet token]

code for the strafe?
