[trim matrix]

You wouldent want to set it there anyways

[ember token]

shouldnt make any difference
@sly spade yeah, in the end I made it, the problem was that I had to use the event thick instead of a random custom event, so I used a sequencer with my other event thick and it worked!Thanks a lot for your help 😳

[trim matrix]

Do you wanna join a call?

[rancid anvil]

Sure if you're up for it that'd be great

Question:
I have a character using root motion, and some node strings that get its forward velocity. However due to my Running animation, its velocity speeds up and slows down. how would get the average of the number values produced by its changing velocity?

im not sure what nodes to use or even where to begin to set this up

[nocturne remnant]

do you need an average velocity or an average speed?

[fossil shoal]

sorry if im taking long to respond im discussing wether or not i actually need this with someone else :<

[fossil shoal]

well upon much argument and discussion I dont actually need this

Nvm and thank you :\

[split ginkgo]

Is there a way I could make a turning radius for my AI?

Right now it looks ugly when moving around because it just snaps to the forward direction

[worthy frost]

#gameplay-ai and adjust the rotation rate in CMC, and use Control rotation not orient to movement.

[sterile quest]

Question: I'm trying to attach a query collision component to my character to detect when the space in front of them has an interactable object (door, something they can pick up, etc...). I'm able to attach it in blueprints just fine and it follows the character and works as expected. But when I instead initialize it as part of my character's C++ constructor, even if I call InteractionComponent->SetupAttachment(RootComponent); it does not follow the character and instead seems to remain rooted at the origin. Moreover, it seems that every once in awhile, the details panel goes blank for the C++ created component. Is there some easy gotcha I'm missing here?

[solemn pumice]

So I’m not sure if this is the right channel to ask in, but I’m wanting to make a pipe system for my game, since it’s slightly focused on automation and machinery.

The pipes are clear with metal frames so the player can see what’s in them. My question is how can I make the items move through the pipe from the proper output to the proper input? I’m guessing it’ll be something with paths but I’m not sure how that would work.

[twilit heath]

@sterile quest blueprint has few serialization errors, the easiest way to break it is to rename your component in c++ constructor

easiest way to fix it is to rename a variable holding a reference to it

and that is the correct way to attach a component in c++ constructor

@solemn pumice i'd look into splines if i were you

[solemn pumice]

Oh ok. Thank you

[twilit heath]

there was a live training stream for splines that wasn't a total disaster @solemn pumice

[solemn pumice]

Are they usually disasters? I’ll go check it out. Thanks again.

[twilit heath]

they are, they do unspeakable things in favor of expediency

[trim matrix]

How do you get automatic widget size?

I want to scale an image accordingly depending on the resolution of the screen.

[covert arrow]

@twilit heath i have a level sequence in my level it plays but after it ends it goes back to its original position how do i leave in the position after the level sequence ends

[twilit heath]

haven't done any work with level sequences, sorry

[covert arrow]

nvm i found its in the properties of the level sequence keep state after finished i just seem to find it if i ask the discord idk its weird

[devout geyser]

Hey guys, I have an Hit animation but I can press mouse 1 to reactivate the animation constantly

How do I add cooldown to the mouse 1 click input?

@bitter star Place the particle in the car bp, then make sure its disabled, place the particle in the car's exhaust, then when the trigger supposed to be activated activate the particle

It won't strech

If its still doesn't work, go to the emitter settings and play with it untill you will get it right

Try using the emitter settings, with the graphs and all of that I am pretty sure there are the settings you are looking for there

[cold leaf]

using linetracebychannel and wondering what i use for the impulse to be based of where the hit it is detected on the bone? Before i had it so it just had a impulse based on a vector meaning it would only react in one direction.

[violet mauve]

I need some help with vehicle AI. I want my car to have a set speed for each spline and have the speed stay consistent. currently the smoothest i can get is getting the vehicle forward speed and if its less than splines desired speed, throttle is 1 otherwise throttle is 0. what is a better way to do this?

[devout geyser]

Try changing the max speed in the AI movement @violet mauve

[violet mauve]

AI movement? i just made a bp that does steering off a spline with a normal vehicle bp

[still trellis]

kind of a weird question, but what are we supposed to be using for things that are just regular classes, not things in the world or components of things in the world? i've been using UObjects but apparently they aren't replicated. I'm talking about things like Stats, Spells, Events, etc. things that aren't actually physical things in the world but need to contain a few functions to modify themselves. I would use structs for this but in ue4, structs can't have functions.

[trim matrix]

I have a stupid question so pretty much i have consumables enum and every enum just restores health cause default is the healing one and so how can i make it to choose the correct one ? xd

[trim matrix]

@still trellis Since objects cannot replicate, you need to have all the data you want replicated stored in place where replication is possible. Like your player state for instance. This could require some work arounds or a different approach.
In a stat system for example, you could have a UObject which is the stat manager. It manipulates and manages a array of different stats. Instead of storing that array on the Stat manager Uobject itself, you could instead store those values on your player state (Or any actor which can replicate). Then you could have your stat manager UObject point to the array on the replicated player state whenever its getting or setting those values.
Another possibility, if you simply need some basic functions to manipulate a struct(Or something along those lines), you can instead use a blueprint function library to hold the functions instead of a UObject. Then you can have the struct variable in a blueprint where replication is possible, and use the functions from the function library to manipulate it.

[still trellis]

using a function library in combination with structs seems like a good option. i dont want to use gamestate or similar because stats should also be applicable to enemies and other players (and for prediction, i want at least some of those stats working on the client)

[trim matrix]

Oh oml just realized i was thinking about playerstate the whole time

But wrote gamestate

Anyways yea tho could store the values anywhere that can replicate

I have a stupid question so pretty much i have consumables enum and every enum just restores health cause default is the healing one and so how can i make it to choose the correct one ? xd
@trim matrix
Can you elaborate on that? Im not sure what the problem is/

so the problem is that when i call the event to when i use an consumable i use the enum to choose the correct function to make the items do different things and when the event happens it doesnt chooses the correct enum, it chooses the default "healing herb" and even when i use the mana herb i still heal and idk how to make it to choose the good one, cause i take the enum -> switch on enum and idk how to make it to choose the good pin on its own probably not a good explanation @trim matrix

sorry for my scuffed english xd

Is the enum your using for switch on enum hardcoded in or something?

Cause if not it seems like an issue with the code that would need to be debugged

@trim matrix

idk what hardcoded means but ok xd

the issue is that i have no experience in programming

I mean do you have a enum varible plugged into it or not basicly

oh

You might have to show me the blueprint then

[violet mauve]

heres a video of my issue. the car seems to bounce because of the throttle going full on full off but other ways ive tried are even worse https://youtu.be/baVDvN6w8gI

[trim matrix]

ok wait but dont laugh at my no skill xd

dw

I couldent tell you seraphiend

ah i see

oh nvm i think i plugged it wrong

xd

Ooh?

Is it fixed now?

yeah im a genius

a programming warlord

Were you not using the consumable enum from the item info or something

yes

im stupid

xd

xD dw

but still thank you xd

np im glad you figured it out

ok so i have another question since you are still here xd

oh yea what is it

how would i go about making a fishing system and making spells a skillshots like a circle on the ground and you choose the position and bang a meteor drops down there or something xd

uh thats not nessicary a easy to answer question

true

but still

wouldnt fishing work like when you have a fishing rod and you are near a water you just click and you have a chance to get a fish or smthg xd

Well really its not a question anyone can just answer. Just a simple fishing system would require alot of moving parts that would ultimatly be pretty unique to your game.

I would stop and think about it for a second exactly how you want your fishing system to work in your game. Make note and plan out all the blueprints and additional functinality your gonna need to code to accomplish it. And go from there.

but you know it doesnt have to be like fishes are swimming and chance that one will swim to the thing and you will catch it but just a simple when near water play animation and get the fishies

[blissful grail]

I'm trying to implement the ability to jump off a wallslide, so do a wall jump pretty much, however, when I add do the LaunchCharacter function, it teleports them. They are sliding down, so when I jump, I should jump backwards, which I have that, but it isn't actually "jumping", it's just teleporting.

Any ideas?

[trim matrix]

there is a tutorial on yt on wallrunning

and you can jump from the wall too

[blissful grail]

I'm not wallrunning, I'm wallsliding. I have the slide already implemented. My question surrounds why LaunchCharacter is teleporting instead of just adding the force.

[trim matrix]

well yea if its that simple then create a trigger volume for a fishing spot or something and create an interact button to start fishing and maybe have it appear on your hud as a button promt. Then could play an animation and spawn a rod in the charecters hand. Then reward player with a random fish

But nobody can just explain how to program that since there's many different little moving parts to accomplish that simple task.

[violet mauve]

ty anyway

[trim matrix]

@trim matrix so how about making a skillshot? would it just be like mouse position to vector2d and then you just play animation and colision in that location that deals the dmg after the animation ends ? x

Im not sure exactly what a skillshot is tho?

like you know you just aim a spell and a circle on the ground that indicates where will it go

ooh i see

[nocturne remnant]

Are you sure that it's teleporting and it's not that you're doing something else with the velocity?

[blissful grail]

Pretty positive.

[trim matrix]

Yea you would need to get the world position of your cursor and then have some blueprint with a decal or something trail that position

@blissful grail doesnt you need to activate the simulate physics to do lauch ?

@trim matrix oh ok i see

[blissful grail]

@nocturne remnant Yeah - it's teleporting

All I'm doing is getting the normal to the wall and multiplying that by x, that is my launch velocity

[nocturne remnant]

how are you sticking to the wall?

[trim matrix]

why wont you just google a tutorial on yt just found in 2s what you are looking for xd

https://www.youtube.com/watch?v=3bOErNKJfeE

[blissful grail]

@trim matrix I am literally asking why LaunchCharacter is teleporting instead of adding a force. Tutorials don't cover that.

[trim matrix]

but you can see how he launched the character

check*

[blissful grail]

That will not answer my question

[trim matrix]

i guess xd

[blissful grail]

My question is WHY is this happening

Not how do I do this

@nocturne remnant For that - jump to the wall, then stop gravity and flip a bool. Then we apply some velocity in the -z to slide down (numbers are not final, just placeholder stuff right now) and then reset the gravity scale back to 1.

[nocturne remnant]

Are you specifically setting the z velocity over time?

[blissful grail]

What do you mean?

[nocturne remnant]

I mean are you using set velocity on the character movement component?

[blissful grail]

yeah

Thinkin' the 0 is overriding the launch character?

[untold anchor]

will need to see the blueprint to know for sure

[blissful grail]

That's exactly what is happening.

[nocturne remnant]

Well, yeah, since you're zeroing out the velocity

[blissful grail]

I just cut that out and applied the launch character to happen once hitting the wall.

Late night. Thanks.

[nocturne remnant]

Since you're disabling gravity, zero the velocity when it hits the wall, addimpulse for your sliding down, then set your gravity and launchcharacter in whatever your jumping off shit function is called

[cerulean depot]

Running into an issue of trying to use a cable component in a Pawn BP, I can add it, test with it in run time and the works fine.
But when I close the editor down and reopen the component ends up removed like it was never added to the components list.
Anyone have a guess what would be the culprit to this issue or would it be a editor bug that I have?

[nocturne remnant]

and you may actually want to use stop movement immediately rather than just setting the velocity to zero

I'm guessing some kind of bug, because I still had an accidental noodle dick on my character. I made a plain pawn and it saved that too.

[true valve]

I need help with a logic

using blueprint

I created a pass time widget where you can use 1 - 8 hours to pass time. I have 24 hours time goes from 1 - 24.

Let's say the time is 22. I open the widget to pass time for 4 hours.

I use global time dilation to speed time. I have the logic working if the total time (22+1=23) is less or equal than 24. But If it passes 24 then what could I add to my logic.

[thorn ermine]

(time + delta) % 24 perhaps?

[true valve]

ie?

What is delta?

[thorn ermine]

the difference to add to the current time

[true valve]

Can you use an example?

(22 + 4) % 24

[thorn ermine]

where the result of an addition ( + ) modulated ( % ) by the limit, would yield the result still within the limit. so 26 % 24 yields 2

[true valve]

I see that but trying to put that in if statement.

So I guess I can store that in a variable

[thorn ermine]

there is no logic required for <= limit. 22 % 24 is still 22

[true valve]

Then as the time increases, I can keep checking (CurrentTime + 4) % 24 == 2

[thorn ermine]

right

[true valve]

I think this is correct: (CurrentTime % 24) == 2

But the currenttime will only go upto24 then start from 1

[thorn ermine]

up to 23, then 0

% 24 = max 23

[true valve]

yes correct

[thorn ermine]

if you want currenttime to be over 23 for other reasons thats fine, but better would be to keep current time modulated directly after any math operations

[true valve]

I get float i cna't use equal

[thorn ermine]

are you incrementing time using fractions?

[true valve]

https://gyazo.com/9fa809e25394411aef5d6e398b8aa279

This one works hopefully bug free

(CurrentTIme + HoursToPass) % 24 = Mod Result

I don't think I could use >= or <=

[thorn ermine]

you can experiment and see what works for you 🙂

[true valve]

Thanks

[faint pasture]

@swift pewter break spawn transform, modify rotation, remake

You basically want to spawn the three projectiles in the same location with different orientations

And use a for loop to do it 3 times

You'd want your projectile not to collide with itself. if collision between projectiles is something that you definitely want, then you'll have to adjust their location as well

[tired saddle]

Currently the smoothest i can get is getting the vehicle forward speed and if its less than splines desired speed, throttle is 1 otherwise throttle is 0. what is a better way to do this?
@violet mauve You can try a PID controller.
https://en.wikipedia.org/wiki/PID_controller#Mathematical_form
https://en.wikipedia.org/wiki/PID_controller#Control_loop_example

Basically, gradually increase the throttle while going too slow and decrease the throttle while going to fast.

There is a pseudo-code form at the end of the Wikipedia article that computer-minded people may find easier to read.

[faint pasture]

@violet mauve

Try starting with

throttle = maprangeclamped (currentspeed - targetspeed, -10, 10, 1, 0)

That'll output full throttle if speed is 10 too low, zero throttle if speed is 10 too high, and smoothly between when in the range.

Tune range to taste

[low rampart]

Hey guys, any ideas how to modify this Content Example for Fluid Simulation to work in World Space around the character and not based on the UV of the mesh, like Ryan explained in a Unreal Fest 2020 session?
https://docs.unrealengine.com/en-US/Engine/Rendering/RenderTargets/BlueprintRenderTargets/HowTo/FluidSurface/index.html

[tired saddle]

@violet mauve

Try starting with

throttle = maprangeclamped (currentspeed - targetspeed, -10, 10, 1, 0)

That'll output full throttle if speed is 10 too low, zero throttle if speed is 10 too high, and smoothly between when in the range.
Yes. That is the P-part of a PID controller. A PID-controller with the I and D coefficients set to zero. currentspeed-targetspeed is what the Wikipedia article call the error value. If that works well enough then 👍 . If not, then look into the other two term as well.

If someone can help would be amazing

Anyone ??

Maybe this can help? @rapid scarab
https://answers.unrealengine.com/questions/854733/keep-a-button-pressed-to-rotate-an-object.html

[rapid scarab]

I tried this but didn't rotate :( also it doesn't say what bp to use etc

@frigid anvil

[frigid anvil]

This works @rapid scarab What are you trying to rotate and with what do you want to control it with?

[rapid scarab]

What bp is this made in ?? And I created a mesh and I just want to rotate it when touch/button is held and then stop rotating when released

[frigid anvil]

So when the item is clicked on you want it to rotate or do you have a widget button?

[rapid scarab]

Either really think it would be better when screen is pressed/held

But at this point I'm just trying to get any button to work lol

[bleak vector]

Is there any reason to use character over pawn if I'm not using the default movement class?

[thorn ermine]

UPawn actually provides the default or pawn movement component ( with very little movement logic in it though ), where Character provides the SkeletalMesh Component as well as the CharacterMovement component. so...

up to you i guess

[bleak vector]

🤔

[odd veldt]

Can someone tell my why this is not working?

LODs are changing, but not the view angle

[thorn ermine]

you have to 'Set Field Of View' on the player camera. rather than setting the default FOV in the camera manager.

[woven saddle]

https://media.giphy.com/media/Urnc8EJaZZ9p3yl0l0/giphy.gif anyone knows why this might be happening? I want it to start at the character's feet, it starts that way but then the base moves up a bit

this is the setup

timeline is just a 0-1 in value (and 0-2 in seconds)

[bleak vector]

I recommend using the ease node 🙂

[woven saddle]

interesting, does that work similar to a Lerp?

[bleak vector]

yeah, with more options

anyway I think you're using the same values

[woven saddle]

yeah I'm trying with ease but getting the same result, the base ends up in the air

ah, I think I know what might be happening

[bleak vector]

you should do something like this

you're getting the current scale on each update of the float and making a change to it

which will set it to the starting value -10, -100, whatever

[woven saddle]

yup that works

the base doesn't float anymore

appreciate that

just need it to start at bottom now

might be an initial scale thing

ah got it

@bleak vector cheers!

HI, i made a health bar widget that is not based on any variable now and added that to my actor, it looks fine in editor but when i run the game it becomes blank

in game:

what could be the problem?

[knotty ore]

possibly the health value isnt being replicated, depending on how everything is setup?

easiest thing to do is just put breakpoints and/or print strings in your BP chain to see where/why its failing

[fair sun]

ok, got it. I accidently bind a function to it

[fair sun]

How can I update the progress bar based on a variable stored in an actor class?

by accessing the variable

[drifting kite]

need a bit of help as a beginner, I currently have something like this in my controller BP. I have a character BP that im trying to control in third person. But now its forcing the character to rotate in the direction of the camera. How should I go about this?

[bleak vector]

Is there a way to clamp an input vector? Specifically when pressing forward and right at the same time I want it to move at 0.5 forward and 0.5 right 🤔

@drifting kite you need to go to your character in the left

and change use controller rotation

Oh, I see that's on the controller not the actor itself

anyway the actor needs to not be set to use controller rotation

[mortal pilot]

you can normalize a vector

that might suit your needs

[drifting kite]

anyway the actor needs to not be set to use controller rotation
@bleak vector when i disable the rotation, the camera completely disables

like i uncheck "use controller yaw" and the camera just stops moving all together

should i combine the character and controller BP?

[bleak vector]

turn orient rotation to movement off

maybe?

idk

I have found problems when putting movement stuff in the controller instead of the actor itself before

specifically, I was doing the forward/right inputs on the controller and sending it to the actor and for some reason it kept getting the wrong inputs

through an interface

don't know why

[drifting kite]

Wait is it possible to just create a project without the controller?

I have found problems when putting movement stuff in the controller instead of the actor itself before
@bleak vector if u can do this, then what is the point of the controller?

[bleak vector]

ai controllers seem to have a lot more purpose than player controllers afaik

[drifting kite]

i see, have yet to touch any ai controller yet 😂

[bleak vector]

@mortal pilot hmm I set it to normalize 1.0 and it made forward/right 7 and forward+right 1 🤔

0.7 that is

[mortal pilot]

normalize will just make it fit inside the unit circle let's say

it makes the length of the vector 1

and if you have x = 0.7 and y =0.7, the length of the vector is ~1 so that's what that's that

but this way makes sure that for example if this is an input vector for movement, that your movement is constant speed

cause if you'd have 0.5, 0.5 then the length of that vector would be ~0.7, so if you'd multiply that with your movement speed, the player would only move at 70% speed of what he would when walking in a forward or directly sideways direction

if you get what I mean

cause I think that was your use case?

[bleak vector]

I'm actually just setting actor world offset

right now if you press both inputs its double the speed

[teal nexus]

I need to turn something "on" when pressing a key, and then turn it "off" when pressing same key again. Kinda like toggle something with the same key. On press I am checking "activated" bool. If it's True, run "turn off" code and set bool to false. If false - run "turn on" code and set bool to true. Sounds like it should work in theory, but it somehow doesn't

what am I doing wrong? Is there a better way of doing this ?

[bleak vector]

could use flipflop but I'm not sure if you can save that 🤔 why is it not working

or rather in what way

[gray kite]

For this line trace, I want it to check and see if the actor has the water tag, but Im not sure how to get it to check all the tags rather than just index 0?

[bleak vector]

did you try the has tag node

[gray kite]

Oh perfect.. lol didnt know that existed thanks!

[nocturne remnant]

flipflop is the way to toggle stuff, generally

Also, your controller should be the thing receiving input and your character is what acts on that input. So, you have an Input Axis MoveForward in your controller, you make an OnMoveForward event inside your character that takes an axis float. Call your BP_CharacterDude->OnMoveForward and pass the axis value from your controller. And then your add movement input or whatever you need to do on the character

[rugged flame]

Hello! BP Newb here, trying to set up a virtual camera with a Vive Tracker. So far it's working, but I'd like to offset the rotation and position of the camera. For example, now it's rotated 90 degrees wrong in relation to how the tracker will be mounted. So, do I plug a value between the GetWorldRotation and the SetRelativeLocationAndRotation nodes? Can this be entered while in play mode somehow? And bonus: Can I move and rotate the whole setup using a second set of controls?

(picture coming) 🙂

[teal nexus]

@bleak vector @nocturne remnant thanks, I'll check out flipflop node

[signal pewter]

Hey. I am trying to create a light chain with rotation. Now i cant just rotate the point light the way I rotated the static mesh actor (which is a candle like object)

instead i tried to add a spring arm component and a light as a childactor of that to get the light in the correct place

what am i doing wrong? (ignore the stuff i plugged out. That is essentially the first idea of just rotating them, before realizing thats not a thing)

trying to get the lights to appear where the lightbulbs are

[nocturne remnant]

your light is set to moveable,right?

[signal pewter]

uhm no its static.. does that matter tho ?

i mean i set up the path once and bake it right? i thought thats the move resource friendly option here

ok so even as movable it doesnt help

[nocturne remnant]

Oh. So it's not going to move. Why not use an emissive material then?

[signal pewter]

i am also doing that in the mesh itsself

but if you mean this..

in the add static mash component that setting is greyed out

[fleet ermine]

If someone could refresh my memory what is the hotkey for creating a reroute node... without double clicking on the line?

[nocturne remnant]

as far as I know, there's not a hotkey

[fleet ermine]

I'm using 4.25.3 I don't know if something has change... I thought it was hold " . " and left mouse click but that isn't working

[nocturne remnant]

unless they added it at some point and never put it in the settings

[signal pewter]

any more clues on why that might be greyed out ? cuz that would indeed fix my issue of adding lights in the first place

[nocturne remnant]

to use a static mesh with an emissive material for static lighting, the mesh needs to be set to static and not movable

[signal pewter]

nice that actually made it turn non-greyed out

ill try from here thanks a bunch

[nocturne remnant]

That's why I thought you were trying to use lights to begin with. Because you can make dynamic lights that will cast shadows, but emissive materials have to be static and baked for shadows

[signal pewter]

so just for testing reasons I turned the numbers up quite a bit but i am not getting any lights on the wall so its not quite working yet

[thin rapids]

so just for testing reasons I turned the numbers up quite a bit but i am not getting any lights on the wall so its not quite working yet
@signal pewter did you rebuild the lighting after doing that?

[signal pewter]

yes

[nocturne remnant]

It works fine for me; are you sure that you have the right material and/or material settings?

[indigo sparrow]

I am using the Unreal CollaborativeViewer Template, I have added an additional command like the ones that come in the template(Measurement,Xray etc)... My command toggles actors visibility based on the Actor tag... The build works fine on desktop, but when I switch to VR mode the application freezes and player is frozen at origin...

I have added the new command to the contextual menu via BP_Collab_V_PlayerController blueprint as shown in the figure above

Here is the contextual menu which works fine in the desktop mode as well as in the editor

I am not able to switch to VR.. Please let me know if anyone has ever had the same issue and has been able to resolve...
Much appreciate any help...

[signal pewter]

LOL in order to test if it might be the material I put a singular light with the material somewhere and set it up similarly.

i mean it doesnt look right but there is indeed light emitting i suppose

[nocturne remnant]

the parent object needs to be static too

[signal pewter]

uhm yea i suppose that did it..

[slim gazelle]

When ever my character is falling and is moving forward they get stuck on slopes
the example is with a slope that is 85 degrees.
they should not be able to stand on slopes greater than 44 degrees
Anyone know how to make them slide of slopes while moving forward in the falling state?
https://streamable.com/mxfqcd

[nocturne remnant]

Does it still get stuck if it's say.. 75 degrees?

[slim gazelle]

yes on every kind of slope that is over the walk threshold

so every slope greater than 44 degrees

walls that are 90 degrees work as intended

[nocturne remnant]

it should be working just fine out of the box

[slim gazelle]

the velocity of the character movement component is being set by root motion for some reason deceleration happens on Z velocity when pushing against a wall

root motion does not effect z velocity.

So I am confused to what is happening here

ok I tested it with a fresh 3rd person project and added this code

my character gets stuck

I am just adding to the already existing velocity

Anyone know what makes my character decelerate on the z axis?

it also happens on a 85 degree wall

[nocturne remnant]

You'll get stuck on slopes if your forward velocity is high enough to keep you pressed up against it without sliding down it

[slim gazelle]

yeah that is right

Now to not make that happen

write my own physics?

[nocturne remnant]

not applying velocity constantly would be a start.

[slim gazelle]

problem is root motion does that

if only epic made a feature for additive root motion like Unity

[gray kite]

Anyone know how I can make an event that happens in a component trigger an event in the components parent?

[nocturne remnant]

I'm pretty sure you don't want to use root motion for general movement

[gray kite]

https://gyazo.com/f5543980b1ba91204e54d42e4cbb0317 Is there a way I can create one of these events from the component?

[violet mauve]

@faint pasture @tired saddle thank you much but im using blueprints. how would i implement this? do i need to do it in C++? if so where?

[faint pasture]

@violet mauve just add a map range outputting into your throttle value

its a node

That would be the P in PID. You are making the control variable (throttle) PROPORTIONAL to the error (Speed - DesiredSpeed)

@violet mauve

You will may find yourself oscillating, depending on friction and vehicle mass and power.

But it'll be better than what you have, which is basically doing the same thing but with a speed range of 0 instead of 100

[violet mauve]

in range, do i change that for my max speed?

and 0 and 1 dont change cause thats the throttle. ok i get it. thank you so much.

i gotta go bac k to work tho. thank you again. i will try it after work

[fleet ermine]

Can anyone in here help me with my question about blueprints...?

I've asked everyone and no one is responding... You'll be a life saver and save me tons of money on headache meds cause I'm going nuts racking my brain on this one... could you please refresh my memory what is the hotkey for creating a reroute node... Without double clicking on the wire? I'm using 4.25.3 and holding " . " and Left mouse button clicking isn't working... Which is what I thought it was...

Please someone respond

[nocturne remnant]

I told you that there wasn't one.

[fleet ermine]

@nocturne remnant I know there was a way to do it... and it didn't involve doing anything like that...

Thanks for responding though.

[indigo bough]

Hey folks, bit of a tracing issue.
Can't seem to get the line trace from the cameras location/forward vector to actually aim directly towards the center of the screen? It always appears offset by some strange amount. I've tried using ScreenLocationToWorldLocation instead and it gives the same imprecise results. 😦

The camera is attached to the head bone of my character mesh (pretty standard)

Basically, my expected results would be that the HUD dot would obscure the line trace perfectly (assuming it's tracing correctly)

[thorn ermine]

for your end, i would imagine you would need to ( GetComponentLocation() + (GetForwardVector() * Distance) ), vs only (GetForwardVector() * Distance)... as it is not taking the camera location into account when calculating the end. also you dont need to use worldrotation, can just use getforwardvector directly form camera.

[indigo bough]

Thank you @thorn ermine ! I'll remove the worldrotation. Turns out the offset was from the distance I was tracing not being long enough. Upping the * value seems to have solved it. Just need to add another check after the trace to make sure it's within a certain distance from the camera to restrict interaction distance 🙂

[gusty shuttle]

Quick question: Im making a repairable object, I want to shoot at it and as it takes "damage" (repairs), I'd like to go from a blown up state to a fixed state on a mesh/skel mesh. Tips?

Is there a way to use a blend anim to adjust the 0-1 state of it?

[teal burrow]

Yes, in an animation BP you can set it up to use a float value for the curve

[gusty shuttle]

Cool, I never dinked around with that. So I guess I need to set up a anim bp to do that though eh? Is there a way to get around it without making a anim bp?

[teal burrow]

You could set it manually in normal BPs but it can be clunky in my experience

As an example, this is in the animBP event graph

[gusty shuttle]

Cool, I'll try it out, if it sucks, Ill make a anim bp. I just need to use a float and gradually go from 0 (busted) to 1 (repaired)

[teal burrow]

"Heresy Level" is a variable within it

Once as a variable, it makes it much faster to run in the animBP

[gusty shuttle]

This is VR, is it performant? I'll have multiple repairable actors in the world for a quest

[teal burrow]

This is a standard thing I do in my characters' BPs, on a 1070Ti there's no significant drops

[gusty shuttle]

Cool, thank sman! I saved the screenshots, ill test tomorrow

[teal burrow]

And this is the Calculate Heresy Level if you need some extra guidance

This is more specific to my project, but for you it'll be just reading a "Health" variable from your repairable object BP

And then using a "1 - x" or directly the variable

[gusty shuttle]

Nice, yeah it's just the health variable, should be easy to set up

[teal burrow]

Aye, in my case it's specific since it's a status effect

But for you it's just 1 variable

[nocturne remnant]

I motion that we require all games to have a heresy level stat

[novel gull]

How can one set up a blueprint system where the collision detection is detected from every angle, whether that be the floor or the ceiling? I have an addon that can change the gravity of my character to any direction, and I want to see if I can apply it to my character and have it be able to freely move around any surface until the character eventually jumps off of it.

[trim matrix]

im a noob so wont help but maybe by tracing every direction

[novel gull]

I tried that, but I can only can get as far as roughly 90 degrees in the pipe before it just outputs nothing. Maybe I'm using it wrong.

[wind atlas]

hello, I'm following a tutorial using editor utility blueprint, but I cant find the GlobalEditorUtilityBase class, maybe its changed for 4.25?

in this tutorial: https://www.youtube.com/watch?v=LXduG19JFWg

in the comments someone says "globaleditorutilitybase is missing in 4.24 , it seems editor utility widget work well"

I think I answer my question, I need to find out what editor utility widget is

ah ok cooool

[pulsar rock]

Hi, I'm creating some procedural building generators. It's working well in the construction script, but I've noticed that when I use Add Static Mesh Component the static meshes don't appear in the component list on the left side of the BP editor. Does anyone know if it's possible to have them appear and be editable?

[trim matrix]

I have a question, how would i go about creating a crafting system

i have the inventory but idk how to do crafting

[rancid crag]

How would I make it so that my camera doesn't flip when on the opposite side of the target

[trim matrix]

chu mean

[rancid crag]

https://streamable.com/tailbz

I'm trying to stop the camera from doing the 180 rotation when it goes on the other side of the target position (marked with a red sphere)

[violet mauve]

@faint pasture thank you that works so much better.

[obsidian folio]

I am looking at seeing if it is possible to do with just blueprint, when the player goes to set their character name, they can hit a button that generates a random name for them.

The name is generated from a free open source api (randomuser.me). Obviously I'd like to do this without opening a web browser on the client lol.

Is it possible through blueprint to get the data through the API? If not, how about would I need to proceed in order to achieve this?

[oblique ruin]

Silly question but is there a node to convert a texture sample to a texture object?
I'm trying to use the parallax material function, but I need to adjust the UV's of the texture object I'm feeding it.

[untold anchor]

Sounds like a python thing

do you mean the tiling and offset? or legit UVs?

[oblique ruin]

So the texture image I have isn't a perfect square.

Right now it's a bid condensed but it's supposed to be a river.

[untold anchor]

i see

[oblique ruin]

I can scale it as a texture sample

But of course texture objects don't allow that

[untold anchor]

the object the material is being applied to, is a rectangle or a square?

[oblique ruin]

Like in the material editor or in game?

in game I have no idea

[untold anchor]

no, like actual ussage

what are you using it for?

a material is applied to an object in game, what is the shape of that object you're applying it to?

[oblique ruin]

a tiling plan ultimately

Ideally it'd be a square.

[untold anchor]

so a square

[oblique ruin]

yeh

[untold anchor]

ok, then you're likely gonna need to go in photoshop

and add space on the left and right sides to make the image a square, if not, you'll be destorting it in game

using a rectangular image isn't an issue if the object you're placing it on is also a rectangle

if you don't have an image editor capable of that, you can upload the image here, and i'll edit and send it back for you, but also blueprints might be the wrong discord section for this , since this is not blueprint related

[oblique ruin]

Thanks I can take care of it

[untold anchor]

if distortion isn't an issue for you, then you could mess with the tiling

but because of how close the black lines get to the left and right edges

[oblique ruin]

Can you alter the tiling of a texture object?

[untold anchor]

you're likely to have issues

yea, in the material properties you can easily change the tiling

[oblique ruin]

Wait a minute

waitttttttt a minute

Sorry I just realized I probably could scale after the parallax and it would do the same thing 😐

[untold anchor]

nice ^_^

[oblique ruin]

Nope nvm doesn't work

Aight I'll take it into photoshop and give what you're saying a try

However somehow managed to overlook the UV option

Which I already had something plugged into -_-

[devout geyser]

How can I add cooldown to my mouse 1 input : graph

this doesn't work

[earnest tangle]

you need to set the can attack to false before the montage

or connect it into the normal exec output pin of the montage to set it to false - note you've currently connected it into the complete pin, which means the montage will have to play to completion

[nocturne remnant]

there's a joke in there

[earnest tangle]

Mmyeah that graph is actually kind of a mess lol

It might be easier to use a gate that gets reset by the delay tbh

Do Once -> Attack -> Delay where the delay then connects back into the Do Once into the reset pin

PIE: Warning: Attempting to move a fully simulated skeletal mesh SkeletalMeshComponent0. Please use the Teleport flag My project was fine yesterday, opened it today and it's suddenly spamming this message. I have a little drone that is flying around using DON's AI pathfinding. It is a skeletal mesh, but "simulate physics" is not enabled anywhere on the actor.

[nocturne remnant]

@untold anchor I'm starting to think that it's fundamentally impossible to get the character facing to work properly without rewriting some source stuff. Shit always tries to flip upside down when changing directions

[untold anchor]

yeaaa, i'm realized i'm gonna have to dive into quaternions it seems :/

haven't done that since college lol, so yay, starting basically from scratch again

however, i'm redesigning the entire wall running system to make it simpler, cleaner and more reliable

then i'll figure out the rotation maths X_X

[devout geyser]

Mmyeah that graph is actually kind of a mess lol
@earnest tangle Ty it worked!

[nocturne remnant]

assuming I don' t die in the next couple of days, I think I'll look into building plugins and do my own quat one

How can I set ref to widget when I can't choose it?

[elfin schooner]

hi im having trouble with some basic bluieprint stuff

in particular i want to display a menu (widget) that i have already created when i click on a certain actor

but its not working

what am i missing?

i also tried to change te mouse cursor when hovering over the object but that wont work either :(

[devout geyser]

Try printing a string after a click to check if the click is regiestered @elfin schooner

[elfin schooner]

didnt work either

@devout geyser

[devout geyser]

Try fixing the click event

[elfin schooner]

i think the problem is that when i create the event actor

its not linking properly to the object i have selected

i dont know how to fix the click evet, i started with this 2 days ago

[devout geyser]

Can you show me the other bp?

[elfin schooner]

which other?

the object im trying to click?

[devout geyser]

yeah

[elfin schooner]

its not a bp

does it have to be=

?

[devout geyser]

Is that an object? or an actor?

ok lets start over ^_^ what are you trying to do?

[elfin schooner]

its an actor i think, im not sure how to check 100%

ok thanks

what im trying to do is

i imported an object from an external project

which is a speaker, for music

[devout geyser]

White circle stands for actor

ok so

[elfin schooner]

lol

[devout geyser]

Yeah its impossible to click on

Because the engine thinks its just a useless prop with out scripts inside him

[elfin schooner]

i see

can i turn it into an actor?

[devout geyser]

Simple

Go to the folder you want the actor at

Right click there on an empty space

Select Blueprint class

Then actor

[elfin schooner]

got it

[devout geyser]

There is a brand new actor that you can make from there, if that's for example a gun, lamp, chair, speaker etc...

you can interact with actors in many ways, if he enters a collision for example and more

[elfin schooner]

ok i dragged the speaker into the viewport

and ill organize the nodes in the event graph and see if it works

[devout geyser]

If it doesn't work i am here

[elfin schooner]

its still not working

im sure its cause im not linking these 2 nodes to the actor

it must be a very silly and basic mistake

[devout geyser]

Umm you don't have on click event

that's why you can't click it

Go to the viewport select the mesh, after that go to the event graph mouse 2 then type on click

[elfin schooner]

ok that sounds good

do i have to also enable click event or something like that?

[devout geyser]

No

Does it work now?

[elfin schooner]

no...

[devout geyser]

What game template are you using?

[native plover]

https://cdn.discordapp.com/attachments/734899596542869504/737945378674049064/unknown.png Anyone have ideas how i can fix this camera clipping while hanging on ledge?

[elfin schooner]

first person character

[trim matrix]

Hey! Can someone help me rq, can someone help me make an "infinite void" room? Ive got a sphere with a plain white texture. I made the mat double sided, and now i need just the sphere to be in fullbright, to create a "void" of sorts. Other objetcs need to have proper lighting though, just this sphere and the floor you stand on

[native plover]

@elfin schooner Any other ?

[elfin schooner]

?

any other what?

[native plover]

ideas

[devout geyser]

@elfin schooner Try instead of mouse input using keyboard input for that, with collision

much more simple with 1st person

[elfin schooner]

with a trigger box i can get it to work

[native plover]

o i thought you were giving ideas XD my bad

[trim matrix]

near clip plane?

[devout geyser]

@tacit citrus You got this, its simple

[trim matrix]

try making the clip plane like 1 or smth

[devout geyser]

i am still here

[elfin schooner]

its this clicking over a bpc that is driving me crazy

[devout geyser]

wait I will try finding a quick solution meanwhile try using the keyboard input

[native plover]

anyone can help me ?

[trim matrix]

@native plover try setting near clip plane to 1

[elfin schooner]

yeah i can pop up the menu easily with a keyboard input

@devout geyser

and trigger boxes

[native plover]

where is that ? @trim matrix

option

[elfin schooner]

the whole point it to try and do it by clicking on the object / actor / bpc though

[devout geyser]

ok

[elfin schooner]

theres the menu

[devout geyser]

Just what I thought

ok

[trim matrix]

edit ---> project settings ---> Search for it (just write "near") Will be a float at a defualt of 10. Make it like 1 or 0.5, then restart your enigne

[devout geyser]

@elfin schooner wait 2 min I think I found solution

[elfin schooner]

🙏

[native plover]

ooo let me try

[elfin schooner]

could it be this? maybe its not supposed to show up as a component

[native plover]

@trim matrix works but now i can see part of the head xd

[trim matrix]

did u set it to 1 or 0.5?

[native plover]

1

[trim matrix]

hmm ok

[devout geyser]

@elfin schooner wait 2 sec 🙂

[trim matrix]

if it 1st person any way you could just remove the head?

[elfin schooner]

got it

[native plover]

is there a way to hide head? @trim matrix

xd

[trim matrix]

not sure if this is it, but try HideBoneByName

[native plover]

i don't mean hide bone

[trim matrix]

lololololol

[native plover]

XD

[trim matrix]

hmm

send me a pic of the head

clipping thru the camera

[trim matrix]

you may need to move the camera a bit back into the head

unless you like the spot its currently in :/

[native plover]

i don't think that will fix it, let me try

@trim matrix

top is fixed

[trim matrix]

now down more???

[blazing cobalt]

could someone please help me on where to start with blueprint, im stressing myself out and wasting out because i dont know where i should be learning. im tired at looking at tutorials and i want to make my own cool projects

[native plover]

@trim matrix nope

ill try to do 1.5 clipping

[trim matrix]

worth a shot

[devout geyser]

@elfin schooner I think you watched a tutorial that says how to destroy a couch right? the template there is having already a working mouse input, now I am trying to edit the controller and sending you the results,

[elfin schooner]

yes i did haha

thats the problem of watching tutorials, there are always different configurations of other stuff that is incompatible with that way your project is set up

i do have a working mouse cursor though

when i go into game mode it looks like thins

[devout geyser]

Sometimes the tutorials aren't that great which makes it 10 times harder to understand

[elfin schooner]

apart from the red cross i have the typical mouse cursor which i can use to click on menu buttons, it just doesnt show on the screenshot cause this screenshot app wont capture the mouse cursor, but its there

[trim matrix]

guys my shaders are compiling in the negatives im scared lolol

[native plover]

@trim matrix not working well 😦

[trim matrix]

yeah i cant help then, that was my best shot lol. All i can say to do is to either keep messing around with it or set clip plane back to 10 and move ur cam back

[blazing cobalt]

could someone please help me on where to start with blueprint, im stressing myself out and wasting out because i dont know where i should be learning. im tired at looking at tutorials and i want to make my own cool projects

[devout geyser]

@elfin schooner I got a solution

[trim matrix]

Arda

[devout geyser]

finally 😄

[elfin schooner]

@devout geyser

[devout geyser]

ok

[native plover]

@trim matrix moving it back look terrible when i aim down

[devout geyser]

Go to your player BP in your case its "FirstPersonBP

[trim matrix]

again, set clip back to 10 if ur gonna go back to the same spot

[devout geyser]

Go to the event graph

[elfin schooner]

yes

[native plover]

@trim matrix no ik, im saying it'll look bad if i do that

[devout geyser]

Mouse 2 in the event graph type "InputTouch" scroll to the bottom of the screen and you should see a little little mouse icon

that says "Touch"

[trim matrix]

again sadly i cant really help you ¯_(ツ)_/¯

[native plover]

sad life

[trim matrix]

you can say that again lolol

[devout geyser]

Like this one @elfin schooner

[trim matrix]

good luck

[elfin schooner]

got it

[devout geyser]

Update me when you done it @elfin schooner

ok

cool

now click it

it will create a node

[elfin schooner]

yep

[native plover]

ty gl with your negative shader compile @trim matrix

[devout geyser]

Drag out the last one called finger index

[native plover]

xd

[elfin schooner]

hmh

[trim matrix]

xdddddddd

[devout geyser]

Type there "==" and select Enum

[elfin schooner]

done

[devout geyser]

Select Touch 1

[elfin schooner]

its selected

[devout geyser]

After that drag out from the red dot and create a branch

[elfin schooner]

done

[devout geyser]

You can simply dragout anything you want from the true

and that's it

[devout geyser]

easy as that

plug in pressed to the branch

and you are good to go

[elfin schooner]

thats it?

i dont have to link the branch to anything?

[devout geyser]

No because the click event is on your speaker

so it will be called whtn its clicked auto

[elfin schooner]

these new nodes are in the first person bp tho

[devout geyser]

its ok

beacuse

ok

[elfin schooner]

and the stuff about the speaker ins in the speaker bpc

[devout geyser]

Ok

You have hands right?

Your brain tells you to touch it

The hands touch it

Lets say there is a light switch

your brain(fp_bp) tells you to touch it

you give your hands(cursor) the ability to touch it

the switch(your speaker) will activate

simple as that

Does it work?

[elfin schooner]

it doesnt seem so..

[devout geyser]

ok its ok

You see your content folder?

[elfin schooner]

this is just depressing

yea

[devout geyser]

Its ok man

You see a huge Add new button?

[elfin schooner]

ye

[devout geyser]

Click it

The top option there is a "add feature something something"

[elfin schooner]

yea

[devout geyser]

Click that then add the top down content

it will take time to load

when it will finish

[elfin schooner]

wait what do you mean top down content?

[devout geyser]

yeah

[elfin schooner]

oh

[devout geyser]

ohh no

[elfin schooner]

yeah nvm

i got it

[devout geyser]

ok 😄

[elfin schooner]

ok its adding

its done

[devout geyser]

ok

now wait a sec ^^

sry

[elfin schooner]

no problem at all

you dont need to say sorry at all

the worst thing is that itll probably be some super minor detail

very obvious thing that im not able to tell

some unchecked box or some weird configuration somewhere

[devout geyser]

I am trying to figure out how to combine the TopDown mod and the 3rd\1st person mode to move the camera with out dragging it around

and just simply follow the mosue

[elfin schooner]

im already using right click to rotate the camera

and wasd to move

idk if that helps

[devout geyser]

I mean is it good enough for you?

Or do you want to change it?

[elfin schooner]

im okay with it

[devout geyser]

so ok

basiclly

find your fpp

fp_bp

click it

[elfin schooner]

the frist person character bp?

[devout geyser]

wait

again mb ^^

If you will look on the top toolbox

you can see

save current source control nodes content and all of these

Do you want a screenshot?

[elfin schooner]

yeas please haha

[elfin schooner]

ah yea

ok

[devout geyser]

open up world settings

[elfin schooner]

yeah

[devout geyser]

Then it will pop up a window

There is a search bar on top of the window

[elfin schooner]

yes

[devout geyser]

don't use the search bar XD i am so bad at explaining, just look for Game mode

you will see many options under this category

[elfin schooner]

found it

[devout geyser]

Select this option right there and select topDownController

[devout geyser]

Oh choose in the 1st option

your game mode

1st person

then on the player controller choose the top down

[elfin schooner]

ive never touched these

[devout geyser]

Always a 1st itme

[elfin schooner]

let me tell you that the point of my work is to export an interactive app

so thats what matters in the end, and where all the stuff has to work

[devout geyser]

ok

[devout geyser]

GJ

it shoud work

100000000%

if not

I will keep digging in

[elfin schooner]

YO

IT WORKS

OMGGGGGGGGGGGGGGGGGG

[devout geyser]

🙂

[elfin schooner]

@devout geyser GENIUS

[devout geyser]

Enjoy man

[elfin schooner]

1000000 IQ

good lord i cant believe

i was about to go to sleep, its 6 am

ahhhhh i didnt expect this

so it was the game mode??

[devout geyser]

apparently yeah

So you were right minor problem 😄

[elfin schooner]

my teacher never told us about those, but then again this is more complicated than what we saw in calss, so maybe i just dug myself into a hole here

yeah minor problems are always the most common..

[blazing cobalt]

could someone please help me on where to start with blueprint, im stressing myself out and wasting out because i dont know where i should be learning. im tired at looking at tutorials and i want to make my own cool projects

please

[devout geyser]

its ok, game developing is about exploring now me and you has a little me of experience 🙂

Happy to help any time @elfin schooner

[elfin schooner]

:)

thanks a ton

[devout geyser]

Np man any time

[elfin schooner]

i super appreciate your effort

[devout geyser]

🙂 always

[elfin schooner]

my work is due in a couple days so you might still find me asking stuff here

specially now that i got this to work, i lost my highlight effect

[blazing cobalt]

can someone please help

[elfin schooner]

which is an effect that workd with normal objects, but not right now with bpcs, so ill need to sweat a little with that

but now im going to sleep

thanks again, you were super nice

[devout geyser]

Have a good sleep man, stay safe

Np man

[elfin schooner]

this is the function btw if youre interested

it makes the desginated object glow with a yellow highlight when closer than 300 cms

but if the object is a BPC or an actor, it stops working

good night !

[haughty axle]

hey guys, need some advice, i am working a lot with procedural generation lately, and have question, i need to make road/path procedural generated, so first: is any possibility to make it from spline (like set points from a to b and it would generate random spline with curves etc..) or is better just to do simple generation with pre made road assets to build road.
this is some of the stuff i working on https://twitter.com/rbutrimavicius/status/1279928116564148224

@haughty axle I think a simple generate will be enough but that's my opinion

[haughty axle]

yeagh i am moving towards that, but trying to figure out with splines what would save me some work 🙂

[devout geyser]

Good luck, I never used splines or generating in general, I think spines will make it harder work because you need to set like I think an array that will be constantly generating every single one of each spine

I made a procedural dungeon once and each actor "room" i put an entrance node and exit nodes "scene components" in them. I made sure the exit nodes were rotated the right way and when i spaned a new room in, I rotated the room to match the exit node then set location of entrance node to the exit node and they matched up good

I deleted rooms using the GameTimeSinceCreated node

[floral quail]

@mellow stump can you share some of the blueprint? 🤔

[haughty axle]

@mellow stump it's cool stuff but its not a thing i am looking forward, i wan to use splines cuz i can attach mesh to spline to generate road, and my world generation takes maps from a list, so i thinking just to do bunch maps with different layouts of roads and then generate everything else on top.

[floral quail]

If you want to instantiate a bunch of actors from somewhere is it has practice to do this from an empty scene?

If you want to make an abstract class with blueprints is that something you can do?

How to record a video in runtime

[midnight kiln]

@thin heart I use to use fraps but now I just use the Xbox Game Bar (if you are using windows)

[thin heart]

@midnight kiln with blue print I need

[midnight kiln]

@thin heart ah, sorry I misunderstood. The only other way I have tried is using the Sequence Recorder, but it's been a while.

https://docs.unrealengine.com/en-US/Engine/Sequencer/HowTo/SequenceRecorder/index.html

It also looks like.. "As of Unreal Engine 4.24, we recommend using Take Recorder instead of Sequence Recorder."

Hope that's more helpful.

[queen hollow]

Sequence/take recorder is only available in the editor (or PIE)

[pale orbit]

t i'm having a very weird problem that no one on the internet had it yet apparently my character can only walk forward/to the right normally crouched

https://streamable.com/yss6dd

[midnight kiln]

@queen hollow thank you for that. I didn't know. :)

[trim matrix]

how's your input get setup in your event graph @pale orbit

[pale orbit]

what do you mean

so i apparently fixed that not entirely but this is happening now

when my character looks at the ground and jumps it gets a high boost

[queen hollow]

@queen hollow thank you for that. I didn't know. :)
@midnight kiln yeah, it was a little annoying when I found out. I guess it’s because you can only create new UAssets from the editor, which take recorder needs

[trim matrix]

lmao @pale orbit can you show me your event graph where you get the axis input data for the movement??

ngl i might not be able to help, but i'm curious as to why these things are happening lolol

[pale orbit]

i think its something to do with the camera/arms mesh

[trim matrix]

yeah definitely with the camera orientation or something

i wish i could just look at the project

i just don't understand how crouching would change the orientation, and why looking down would cause you to jump higher.. i mean i know how looking UP could make you jump higher

so weird lol

Anybody that can help me with Fluid Sims in Unreal? Or what is the best channel here to ask? 🙂

[pale orbit]

So i changed to my revolver and its fine

but the ak thats happening

dude wtf

[trim matrix]

lmao idk if you upload the project somewhere i would totally look at it and try to sniff it out

assuming it's not like a grand huge almost finished deal

[pale orbit]

where do i upload it tho

its also like 1,8/2gb

[trim matrix]

zip it up and throw it into dropbox or something

oh well if it's 1.8

@low rampart i didn't dabble myself, but when i was looking into it i think i decided my best best was this guy https://www.patreon.com/cannabis_cod3r/posts but patreons costs money. not sure where to start for free

[low rampart]

Well i'm trying to recreate the technique used in Fortnite as shown in the Ryan Brucks session for Unreal Fest 2020. The simulation is kinda in World Space around the character. Currently my setup works with SceneCapture but relative to the mesh plane of the water. If i attach the camera to the player, it looks as if static objects are moving and the character always in place in the center

[trim matrix]

there's an example in the starter content if i recall correctly

if you want to deconstruct it

[low rampart]

yes but as i sad that is relative to the mesh, i need this to be in world space 😄

[trim matrix]

i think i'd have to see fortnite's water, cause i'm not sure what you're trying to do exactly

[low rampart]

sure

[trim matrix]

hmm but why do you need it in world space? he's talking about the boats like it's just regular old 2d rendertarget

lmao i should've waited 5 seconds

yeah man he specifically says they use the same method as the one in the content examples

they just use 2 channels

OH i think i know what you're saying dude

the camera, you should attach it to an actor that you spawn in the world then attach it to the pawn, not attach the camera directly to the pawn

is that what you mean?

[floral quail]

@pale orbit i think maybe your AK is colliding. Causing the jump to get the collision boost

[trim matrix]

@pale orbit i think maybe your AK is colliding. Causing the jump to get the collision boost
@floral quail smart.

[floral quail]

Thank

[trim matrix]

@low rampart is that what you meant?

[low rampart]

well, yeah. In Fortnite when the character moves it acts like a "mask" of what the character sees around him, and on my example its like the characters is static and objects are moving. So dont know what the solution is. The camera is spawned in the world and is offseted then based on the movement @trim matrix

Im using this example, just trying to make it a Fluid sim

lmao whoah, i've followed the same one to get a dunebuggy driving in sand dune effect

i remember getting it to work perfectly, are you just stuck on a part?

that sounded condescending, it wasn't without trial and error though

lemme open up that project real quick

[low rampart]

plenty of hours of trial and errors, dont worry 😄

[trim matrix]

@low rampart this is what i used to update the actors location

[low rampart]

same 🙂

[trim matrix]

well it's not that lol

hold on

[tired saddle]

could someone please help me on where to start with blueprint, im stressing myself out and wasting out because i dont know where i should be learning. im tired at looking at tutorials and i want to make my own cool projects
@blazing cobalt Sounds to me you're using tutorial wrong. Your should have a project from the start and with each tutorial you watch you should apply what you learn to your project. Immediately.

Watch, replicate, experiment, fail, read documentation, fix, back to watch.

[keen seal]

Does anyone know how to make a gun shoot 3 projectiles at once?
I have 3 spawn points, but I don't know how to make them all activate at once

[visual shell]

Assuming you have the points in an array. You use a for each loop to activate them "at once"

[elfin schooner]

hi guys, i need help with what im sure is a problem with a very simple and basic solution. i have the following function in the level bluprint, which measures the distance between the player and a given object and if the distance is less than XX, the object get highlighted through a setting in the post process volume and render custom death:

it works perfectly for normal objects but i need it to work for actors and BPCs as well, so i need so swap the nodes circled in red by their equivalents for BPCs but i dont know how to do it without breaking the entire thing :(

because for example "get distance to" seems to only work for regular objects

(im very noob, i ony started with blueprints 2 days ago)

[thorn ermine]

curious, what is a bpc? are you referring to a blueprint component perhaps?

[trim matrix]

@elfin schooner you might try :

1. avoiding tick,
2. using a sphere trace and testing for all objects that meet your criteria whenever the player pawn moves or performs an action that warrants a seek of such objects

the reason you want to avoid tick is that it is expensive if you keep seeking objects. tick should only be used as a last resort

[thorn ermine]

you can calculate the distance to anything by subtracting 2 world locations from each other, and simply getting the vector length.

[elfin schooner]

@thorn ermine blueprint class

Ok thanks guys I’ll try it in a bit

From a beginners standpoint it seems pretty annoying that you have to do it in such a different way for such a small variation

[trim matrix]

if you're "getting the distance to" either one object or an array of objects or get all objects of type it's very inefficient

yeah

the standards though. i guess i just get used to them

once you develop the commonalities you can probably keep them as part of a toolkit you can use if you need to do it again

[elfin schooner]

I was using tick because I literally could find another way to keep that event going all the time

[trim matrix]

how is your player moving?

[elfin schooner]

Since I need it to be checking the distance all the time

I move my player with wasd

[trim matrix]

call it on move event

[elfin schooner]

In game mode

[trim matrix]

either that or

you can have a timer

and call it in a timer

if you do tick, it's very rapid-firing

up to you though. hope it works out

[elfin schooner]

I tried to use a timer yesterday but it I ended up discarding for a reason I don’t remember

[trim matrix]

i have a ton of timers in my game code that do stuff like that

ah ok

[elfin schooner]

I’ll look into it again tho

Thanks

[trim matrix]

perhaps there was a delay before the highlight and the delay was unfavorable?

simply increase the timer frequency to just enough to the point it becomes bearable

doing it from movement is a good idea though. that way it only fires when the character has movement applied to the axis.

because how else can it be updated, right?

unless there's a force applied to the character or the character position changes in another way

so if you use the standard unreal axis movement stuff, you can simply trigger the sphere trace on that axis move

and one more thing i will add, don't use sphere trace by channel, use sphere trace by object to filter your objects properly

[elfin schooner]

i think it was more of the fact that im new and it seemed to complex, or that the operation didnt worked for regular objects, which is what i was using at the time

[trim matrix]

k

in any case, you're getting more advanced now, right? 🙂

[elfin schooner]

i cant test now but ill let you know when i do in 30 min or so

[trim matrix]

cool

[elfin schooner]

more advanced than i can manage...

[trim matrix]

haha be glad it's not c++

blueprints really helped me get into coding

[fair sun]

hey guys, im making a health bar that is filled based on a value stored in an actor class

so far it looks like this

how can i get the owner of the widget>

I`ve seen people do it with get player charater but this health bar is not going to belong to the player

[mellow stump]

GetActorOfClass, GetAllActorsOfClass, GetActorWithInterface, GetAllActorsWithTag, theres quite a few ways to get a Reference to an actor.

[fair sun]

Thanks

[trim matrix]

@fair sun can also try this: ```In your Blueprint Widget, make sure that the text component you are using to display the name is marked as IsVariable in the checkbox.

Now, make a new blueprint class deired from Widget Component. Set the Blueprint Widget you have created to be the "Widget Class" in default settings. Use GetUserWidgetObject and cast to the widget blueprint. From the cast node, get the text variable component and call set text. You can call GetOwner->GetDisplayName to get the display name to you want, and plug that into the set text.

Use this new widget component you have created in the AI characters, and you should be good to go.```

are you calling the return node from within the widget in umg?

to have a percent indicator ui or something?

[fair sun]

I'm sorry but I don't understand the question so I guess no

[trim matrix]

where is get percent 0

[fair sun]

inside my HealthBar widget class

[trim matrix]

ok yeah then its in the widget

so you can try getuserwidgetobject in there

if that doesn't work try Get Owner

[fair sun]

cant find getUserWidgetObject function

and for the owner i only find the player owner

[trim matrix]

try taking off context sensitive?

[fair sun]

got it

thanks

[trim matrix]

cool

[fair sun]

for both i get these errors

ok got rid of the second one

that was caused by a missclick

[trim matrix]

@fair sun is the widget always going to be called from a player? or an enemy AI or other object?

[twilit heath]

GetUserWidgetObject is a function on the WidgetComponent

it needs a WidgetComponent referrence to work

turning off context might not had been the best idea here

[trim matrix]

here is an example of me using getOwnerPlayer but i suppose it wont work if it's not a player so..

[fair sun]

the healthbar is going to be a component of a trainingDummy actor class

[trim matrix]

@fair sun this is how i do it in my game

for this shield bar

@thorn ermine any tips here?

[thorn ermine]

sorry, i was in the wrong window

[trim matrix]

how to get the ui to show his float value?

ok

@fair sun might try get owning player pawn even if it's a training dummy actor class

[thorn ermine]

oh hang on, are you using a widget component, with a userwidget set on it? then you first have to get the widgetobject, and cast it to the correct widget class and then you can set values on it. if i am understanding correctly...

[trim matrix]

here's an example of the casting @fair sun

[fair sun]

okay thanks, will try that in a sec

[trim matrix]

try what alwynd said too if it doesn't work

haha

@thorn ermine are you devving a game?

[thorn ermine]

we are working on 2 unreleased titles at the moment yes. trying to get the stuff in a demo state

[trim matrix]

cool

[thorn ermine]

you?

[trim matrix]

do you guys have a discord? i can DM you maybe

yes very much so

i am doing 4 games now, solo devving it

2 unity 2 unreal

[thorn ermine]

yikes!

[trim matrix]

haha lots of work

but i alternate

when i get tired of the ue ones i go to unity lol

[thorn ermine]

we do not have discord no. 🙂

[trim matrix]

i should say 3 of my games are full-ish, one is kind of in late alpha

so i suppose it's technically 3 and a half

haha

[thorn ermine]

https://tenor.com/view/brooklyn99-noice-jake-peralta-andy-samberg-nice-gif-14234819

[fair sun]

for get player pawn i get a warning that the cast will always fail

not sure about that getwidgetobject

i cant find that function inside blueprints

[twilit heath]

where is your widget?

directly in viewport

or on widgetcomponent on the pawn?

[fair sun]

I made a healthBar widget bp, added a progress bar to it and then added it as a widget component to my actor bp

[twilit heath]

then add a variable of your actor type to the widget

on your actor's BeginPlay, pull a reference to the WidgetComponent, from that reference, pull GetUserWidgetObject function, then Cast the result to your Widget's type, and then pull a reference to Self and set it as your Widget's ActorRef

[fair sun]

perfect

thanks for your help everybody

[elfin schooner]

@thorn ermine @trim matrix i used the method that alwyn suggested and it works, it highlights the BPC, but i think something about the calculation of the distance is wrong, because the bpc stays highlighted no matter the distance, when it should only be highlighted when the player is less than 100cm away

it stays like this during game mode

no matter the players position

wait i might be doing the substraction in the wrong oder

[thorn ermine]

100cm is very close. order wont matter no.

try something like 500, and see

[elfin schooner]

i changed the order and made it 200cm but its the same

[thorn ermine]

then gain, its always less than.. you can also try and print the result distance using the print function, and remove it afterwards.

to see the actual value, you of course are using the distance of the correct actor? not the same blueprint actor?

so SM L Deco speaker is a variable from ( another actor ) somewhere else ( or a blueprint component within the same blueprint that can move dynamically apart from its parent ), not the same blueprint? otherwise the distance will always be 0. because they are located at the same place... or what?

[elfin schooner]

i got it from there

from inside the BPC

[thorn ermine]

right, makes sense it will always be zero, you are taking the distance form the speaker to its parent

perhaps you want to take the distance from another actor?

so the speaker, and the player?

[elfin schooner]

oh wait

[thorn ermine]

or the speaker and some projectile

[elfin schooner]

this shopuld be the player location! not the actor

[thorn ermine]

huzaa

[elfin schooner]

i cant call it though

[thorn ermine]

to get the player you can get it from anywhere at any time. except in a material. 🙂 and an animgraph

one second

this is a global blueprint function

available "everywhere"

[elfin schooner]

yep

i tried this and it seems to work

kinda ugly but yeah

[thorn ermine]

one thing though

[elfin schooner]

yes? about the event tick?

[thorn ermine]

from your get player character, call IsValid on it first, if the game for some reason ends, that tick will crash

in a packaged game, it will throw a nasty windows error

[elfin schooner]

its an aparment tour, the game can only end by exiting the app

oh

[thorn ermine]

yes, even so

[trim matrix]

@elfin schooner are you going to get around to converting it to SphereTracebyObject ? 🙂

[elfin schooner]

@trim matrix i dont know what that is but if i can do it, yes

although i dont have a lot of time

[thorn ermine]

and actually that is a better idea, coz you kind of implemented an overlap sphere

😛

[elfin schooner]

so i have 3 things to correct?

the tick
