@tight venture what i wanted to do was that I have a character that walks through a cave and then when it is in radius of an object that is pickup-able the player can just stay stationary and the item will execute a func, do you know how i would do that

carmine thorn Jun 17, 2020, 10:45 PM

#

i like calling it the origin point... pivot point is not as accurate IMO
@tight venture Pivot point is perfectly accurate. Origin point refers to the center of the world <0,0,0>. Pivot point refers to the point from which an object pivots, i.e. it's center of rotation. The two are not the same and should not be confused.

tight venture Jun 17, 2020, 10:46 PM

#

@harsh topaz

Add a collider around the object you want to get picked-up (in its blueprint), coinciding with the area where it becomes "pickup-able".
Check the collision settings for both the collider and the character, make sure they have either overlap or block for each other, and they both must have "Generate Overlap Events" ticked.
Add an Event OnBeginOverlap node into the Event Graph for either:
a) The picked-up object's blueprint (attached to the collider)
OR
b) The character's blueprint (probably attached to their main mesh)

carmine thorn Jun 17, 2020, 10:47 PM

#

Although to be fair in some 3D software when you export, the pivot point tends to become the origin point of the scene in the 3D software.

tight venture Jun 17, 2020, 10:47 PM

#

@carmine thorn fair enough

#

thx btw, I found it. I think. Not doing what I thought it would do though

carmine thorn Jun 17, 2020, 10:48 PM

#

Yeah it can be a pain to work with. Only works when you reimport the file

#

No problem

tight venture Jun 17, 2020, 10:49 PM

#

I think I'm just gonna make that mesh a child of a placeholder root scene component (like it is by default), then just move it against that

carmine thorn Jun 17, 2020, 10:49 PM

Yeah that would do it

Hey guys. I'm new here to this server but been using Unreal now for a couple of months trying to make a game. I got stuck on making a weapon equip and unequip system however. I know the logic of having an Overlap and end Overlap event when going over the weapon and using my interaction input event to grab the weapon and drop using E. However I just can't for the life of me figure out how to get it working. Is there anyone here that can possibly help me out. Maybe even enter a call and I can screen share. I've been stuck for like a week now and I'm seriously willing to go as far as even paying whoever helps me with this.

When using attachtoactor on Actor A to Actor B, Actor A's location is instantly transported faaar away. Does anyone know what I may be doing wrong? I was assuming that from the moment of being attached, Actor A's transform would just be parented to all new movements from Actor B?

#

I'd assume that a passenger getting into a vehicle and then moving with the vehicle would be akin to using attachtoactor?

hardy merlin Jun 18, 2020, 5:28 AM

What Attach Type are you using?

There are options to snap to the parent, preserve world position, or make the child's current world position the local position.

@maiden wadi Hi there buddy, hope you don't mind me pinging. So I've been playing around and tweaking my radar tracking etc and on the whole its working great. But i need a little help debugging some odd behaviour. It seams that all my tracked objects are not being treated individually - All the relative velocities seem to be affecting each other in a strange way - for example the more object being tracked the more the velocities are altered. they aren't being compared to just the player camera location, and they are being "grouped" rather than calculated individually. Hope that explains it 😆 👍

deep elbow Jun 18, 2020, 11:27 AM

#

you're setting actor location, drag off your door mesh/component and find "set location"

#

actor will move the blueprint root and everything parented to it

#

set world or set relative location

#

you're probably going to choose Set Relative Location,. then all movement is relative to the root of the blueprint

#

and instead of getting the world location and setting that as a default value you cause just skip that entirely and presume that 0,0,0 is the starting location

#

or get the relative location of the door if you have moved it in the blueprint and set that as the door starting loc

#

make sense? @midnight elbow

midnight elbow Jun 18, 2020, 11:31 AM

#

Im so new to blueprints, i just deleted everything after the timeline to start over. so from update i need to set relative location

deep elbow Jun 18, 2020, 11:31 AM

#

better explanation: actor is a blueprint, something that can be placed in a level, component is something inside of an actor.
a static mesh placed in the level is a StaticMeshActor, and has a StaticMeshComponent. the component is the actual "mesh".
same applies to blueprints, the Actor is the blueprint itself, the Components are things inside the blueprint

#

I presume you are watching a tutorial for setting up a door? Most tutorials put it in the level blueprint (bad practice) so working on Actors is fine in the level blueprint, but doing it inside a blueprint you'll be working on Components

@midnight elbow what do you think is wrong? are all pins hooked up? one of the timelines looks different!
a note: the Update output of a timeline happens every frame, so it gets called very often, you shouldn't think of it as happening only once. you won't notice an issue with your current setup because of how timeslines work, but if you put the exec pin into PlayFromStart yu'd notice odd behaviour

set Z to 99999

#

or whatever high value

deep elbow Jun 18, 2020, 12:42 PM

#

that is also not old-school movement, the character will move diagonally, i presume they want it to be locked to 90degreee directions, which will probably have to be done via set actor rotation and using a snap

yes but if a release my movement, it go back to the starting rotation

then that's specific to your game :/

no clue what it drives the movement apart from the defaults

Insert will add to the array on the specified index. Everything else will then get moved one index. @vivid plinth Does not replace

Yes, it should have been clearer. The node Set Array Elem will 'replace' whats in the specified index. Which means the array keeps its size

vivid plinth Jun 18, 2020, 12:55 PM

right gotcha. I was surprised just now, I looked and I could have sworn there was a "replace" node but there isn't. Used Set Array Elem before. Huh weird

So hey question I have a simple (and I do mean simple) C++ class that I made a BP (based on) and when I make a object reference variable to that BP I get an access none violation and I'm not sure why

thin rapids Jun 18, 2020, 1:18 PM

#

@dire onyx where are you making that object reference variable?

dire onyx Jun 18, 2020, 1:18 PM

#

In my Character class BP

fair coral Jun 18, 2020, 1:19 PM

#

if i read that correctly than the problem should be that you cant reference from c++ to blueprint cause blueprint dont really exist at compile time

thin rapids Jun 18, 2020, 1:19 PM

#

and are you setting that reference using a cast, a spawn actor, how exactly are you getting that reference?

dire onyx Jun 18, 2020, 1:20 PM

#

I just create a new variable and make it of type (well in this case) WeaponBase (which is the BP in question) here let me post a quick picture

#

📎 Untitled.png

thin rapids Jun 18, 2020, 1:23 PM

#

and are you spawning that weaponBase in the player?

dire onyx Jun 18, 2020, 1:23 PM

#

Yes that function spawn rifle works just fine. It's the variable that isn't working

fair coral Jun 18, 2020, 1:24 PM

#

are the UE macros set for blueprint use /write whatever correctly?

dire onyx Jun 18, 2020, 1:24 PM

#

Let me check that real quick

thin rapids Jun 18, 2020, 1:25 PM

#

did you make something similar to this, or a cast?

📎 bbbbbbbbbbbbbbbbb.png

#

because you cant get an empty reference

#

because if you try to reference something by just having a variable it's going to return none, you need some sort of connection between that variable and what you're trying to reference

dire onyx Jun 18, 2020, 1:28 PM

No my spawn rifle function works just fine. It's the variable that is giving me problems

@dire onyx where are you calling that variable?

dire onyx Jun 18, 2020, 1:32 PM

#

@thin rapids Well trying to call that variable inside my player BP, the variable itself is based on my WeaponBase BP

thin rapids Jun 18, 2020, 1:33 PM

#

@dire onyx ok, inside the event graph are you setting that variable to anything (like in here https://cdn.discordapp.com/attachments/221798862938046464/723166496372686878/bbbbbbbbbbbbbbbbb.png ) ?

dire onyx Jun 18, 2020, 1:36 PM

thin rapids Jun 18, 2020, 1:37 PM

#

ok, so what is happening is that the variable has the value of NONE, if you try to call that variable without setting it to anything, it's going to get that access none violation @dire onyx

dire onyx Jun 18, 2020, 1:37 PM

#

Is that because it's based on a C++ class? and how do I fix that?

#

Also thank you so much for your help

thin rapids Jun 18, 2020, 1:38 PM

#

no, it's because you're referencing an empty value

#

ok, so are you using a spawn actor node for that weapon?

dire onyx Jun 18, 2020, 1:39 PM

#

No that Spawn Weapon function was created in C++, can post the code if you want to see it, but that function works fine

thin rapids Jun 18, 2020, 1:41 PM

#

then you can set that variable in c++, for example 'CurrentWeapon = GetWorld()->SpawnActor<class>(params);

#

just an example though

dire onyx Jun 18, 2020, 1:42 PM

#

Ok but doesn't that create a variable that is based off the C++ class vs the BP class like I'm trying to do?

thin rapids Jun 18, 2020, 1:42 PM

#

but you need that variable to be set to that spawned actor, and you're doing that in c++, you can expose that to bp later.

#

so you can get the reference to that

dire onyx Jun 18, 2020, 1:43 PM

Oh, ok I think I understand lol

#

@brisk knoll Hidden just hides the object but does not 'take it out' so to speak. Collapsed will act like it no longer exists there. The best test for the difference might be something like a vertical box with three objects in it. If you hide the second one, it just goes invisible, nothing should happen beyond it not being visible and not clickable. If you collapse the second one however, the third one should move up and take it's place.

@jolly jay You skipped the step of finding out where the actor is in the world. Right now you're just finding which direction it's facing and setting it from the center of the world at 0,0,0

What this is doing is getting the actor's facing direction, multiplying that facing direction by 30 to find 30 units in front of the actor, then adding that to it's current world location.

mossy robin Jun 18, 2020, 2:47 PM

#

@jolly jay do you want to make a teleporting function? Then don’t use set actor location use “teleport” actor

#

And get actor forward vector and multiply by 30 to make it teleport 30 units simple

#

If you want the character to teleport to an objects location, just get the actor and get it’s world location and then link the node to the vector part of the “teleport” node

#

You can choose to leave the rotation and others as they are (0:0:0)

chrome quiver Jun 18, 2020, 5:08 PM

Working on player movement, when clicking a location I want the player to finish going there, but when held I want to stop the player's movement with the release.
I thought perhaps I could still use the Stop movement feature, as it can stop the player movement when I like, but I also only move when a key is pressed in the first place, so I can't seem to tell it to do something when it's not pressed within that without issues.

Right now it just never calls the Stop Movement

Couldn't both just use simple move to and then you do the time check on release to see if you should stop movement or not?

Hi,
I have a use case where I am going to need to use 2 attach to socket nodes, many times within my project...
the only thing which will be different is the names in the sockets...
I wanted to make a macro or a function, but they wont work for this because I cant have different socket names in each of these macro/function nodes right ?

that means I only have 2 options right ?
I.e just deal with the eye sore and copy/past over and over, the nodes/ variables as many times as I need to in my BP's...
OR
Do the same as above but just go around afterwards collapsing the nodes ?

anyone have an opinion/ better idea ?

chrome quiver Jun 18, 2020, 6:23 PM

#

If there's an eye sore there is always a better way, haha. I haven't used macros much myself but I think you might be able to accomplish what you want with them, I'm sure looking deeper into macros would be a worthy venture as you might stumble upon something similar to what you want. @dapper cradle

dapper cradle Jun 18, 2020, 6:27 PM

#

thank you for the reply @chrome quiver but when you make a macro, what ever you change in one macro, is changed in all places which that macro is used.
I am pretty sure that is how they work (which is good when you want to change something and have it changed verywhere).

but I need to be able to change the names which go into the 'socket name' boxes of the attach component nodes, these names will be different in each case.
for that reason, I wont be able to use a macro for it.

chrome quiver Jun 18, 2020, 6:28 PM

I think there's a way to just make your own nodes..

dapper cradle Jun 18, 2020, 6:42 PM

#

@dense mantle I am not totally sure what you mean,
but to give you an idea, I have used anim notifies to create events within animations, in each animation there is between 2-7 events.
I have lots of animations at this point.
Each event will be attaching SM into and out of sockets in the skeleton of an animation.
therefore, this will be pretty much a copy/paste job and change names.

I was wondering if there was a better way.

@chrome quiver The Stop Movement function may be useful, it should stop pathing. I'm not sure how it works to have pathing as well as movement control though. You can say something like "OnInputAxis: If the axis value is non-zero, stop movement, and add the movement input. Otherwise, don't do anything"

#

@soft swan Is there a reason you're not using the "Finished" execution line? Then you just say "On Finished, set actor to visible"?

#

In addition, you set New Hidden to true when it should be false so it is no longer hidden.

is the level the only place to store objects? 🤔 even if you construct a class object it gets dumped into the world, right? and if you try to store the class as a variable it's only a pointer to that scene object, right?

#

I suppose there's also actor components

long fox Jun 19, 2020, 5:57 AM

#

@bleak vector you could also get all Actors from class in your BP

Question: is it possible to change player's movement component at runtime ? Or change player's BP altogether ?

How do I make a player controller that can be moved around with AddForce, and I can also control the slow down rate (ground friction/air friction)
Ive tried to use physics without gravity but when I bump into stuff it messes a lot of stuff up including position and rotation of character, sth like the original FPS controller but with addforce

@chrome quiverive looked through it but i kinda want it to be able to bump into other stuff and not bounce back, like how you walk into stuff in tps character

Heya! How could I add a component to an Actor via a function from a BP Function Library? From what I'm seeing, a function created in a BPFL doesn't implement the "Add __ Component" node (which makes sense- the BPFL inherits from Object Class and not Actor Class) I can't think of a workaround for this in order to add components via a BPFL function - anyone have any ideas?? Thanks!

@severe ruin You can not directly attach two objects by it's sockets. Only one Object to another using it's socket. However, you could use the relative position of the original objects socket to offset it after attaching it to the socket (because it will use the pivot when attaching it to the socket of another object)

@maiden wadi Hi there buddy, hope you don't mind me pinging. So I've been playing around and tweaking my radar tracking etc and on the whole its working great. But i need a little help debugging some odd behaviour. It seams that all my tracked objects are not being treated individually - All the relative velocities seem to be affecting each other in a strange way - for example the more object being tracked the more the velocities are altered. they aren't being compared to just the player camera location, and they are being "grouped" rather than calculated individually. Hope that explains it 😆 👍

Just wondering if its possible to get the point where 2 landscape paint textures meet

dusky axle Jun 19, 2020, 11:50 AM

#

using HUD class is deprecated, isn't it?

lavish ibex Jun 19, 2020, 12:01 PM

#

So I’ve got an idea but I need to be pointed in the right direction to know what I should look for.

#

I have a float called “CurrentArmorValue” on an actor BP_Armor. On my BP_Projectile that’s spawned when I fire, it has a “PenetrationValue”. Current, Armor blocks all projectiles.

#

What I want to have happen is on a collision or overlap, check if penetration value on the projectile is higher than current armor value and, if so, pass through BP_Armor. If not, it should collide as normal.

#

Where do I start with the collisions? I can do the value comparisons.

twilit heath Jun 19, 2020, 12:03 PM

#

linetracemulti, i'd go with by channel

#

so you'll get the armor and the character hit every time, if no collision is set to block

#

then you go through your multiple hit results

#

and figure out if armor should stop it or not

#

@dusky axle whatever gave you that idea?

#

@lavish ibex basically you have both armor and character set to overlap projectile trace channel

#

you iterate through your hit results, if you find an armor hit and if the penetration value is insufficient to penetrate the armor, you just ignore all hits after that

#

(character can block projectiles here, its just armor that has to overlap)

lavish ibex Jun 19, 2020, 12:08 PM

#

Oh so it might be a collision settings then, then. I should have it generate overlap events, but not block the projectile? (It’s an actual moving mesh).

#

Though that’s really helpful for linetrace weapons, too.

twilit heath Jun 19, 2020, 12:09 PM

#

doesn't matter really

#

it would be far easier to do in c++, if you have that in your project

lavish ibex Jun 19, 2020, 12:09 PM

#

Willing to learn it. Just doing a quick BP proof of concept.

twilit heath Jun 19, 2020, 12:09 PM

#

as you get much better control over traces and responses

#

in every case, i highly recommend you add a trace channel for projectiles, and collision object type for your armor

lavish ibex Jun 19, 2020, 12:10 PM

#

Okay great. I’ll take a look into that.

@sick sapphire just move your pawn manually based on a velocity value you store. Ie. holding W increases velocity by some amount, and every tick you move the pawn by timeDelta * velocity

maybe some other ways to do it as well but that's probably the most straightforward method

@zenith iris you want to do a ForEachLoop to sort through the array of points and select the one with the minimum distance. Create and set a TempDistance float variable to a very high value, then for each point plug its location into a vector distance function and compare against the character’s location. If the distance is less than the TempDistance float, set its distance as the new TempDistance and create and set a vector variable as the SelectedPoint vector

#

instead of raw distance you could find path length if you are using pathfinding and want to find the shortest walking distance

I have an actor with a widget component attached. This i actor also has a billboard component, which is what you see in the images ( the dot ). This actors widget component is assigned a widget UI. When clicking the UI it should open and display content in the 3d world. Using this through PixelStream when clicking the Actor with the widget blueprint with the mouse, it doesn't register an onclick event and the UI doesn't open. I can cast a ray from mouse cursor to see what i hit, and i get the proper Actor. However, when i click anywhere withing the top right corner of that HTML overlay, and then proceed to go click on the actor in the scene, it all of a sudden works and the UI opens. Any ideas as to why clicking the HTML content on top right corner would all of a sudden make my widget behave as expected in the scene?

@flint nymph kind understood it, but I'm not sure for my case. I'm doing a simple endless runner to practice. I've decided to have turns in it, as well as having fixed lanes to run. I think in my case will be better to get my current lane and it's location and move my character there, right? But there's also the speed, for some reason when I make the turn, my character still moves a little forward in the direction it was moving before the turn.

Is there a node in material blueprints that acts like a array for textures?

you can do sub uv or flipbook texture , like a texture atlas basically

or you can do a dynamic material

and set the textures from regular blueprint

#

which u can then use an actual array of textures

wet mountain Jun 19, 2020, 6:53 PM

@static charm thanks, but im not sure how I would work around my other blueprints/needs, a texture atlas is probably out due to the size of each texture

yeah then you would use a dynamic material

and set the texture from regular blueprint

its a little weird to setup at first, but once u do it, it's really easy to do some powerful stuff

wet mountain Jun 19, 2020, 6:55 PM

but how would that work? i get a variable lets say from the blueprint and set it in the material parameter collection and bring it into my material

#

how do i assign a texture to a number

inner ginkgo Jun 19, 2020, 6:55 PM

#

Depends on the use-case.

#

If you want all mats to change, then param collection works. If you want one mat to change, then create a dynamic material.

wet mountain Jun 19, 2020, 6:56 PM

#

so i can bring up from my variable the desired texture

static charm Jun 19, 2020, 6:56 PM

#

the texture itself will be it's own single parameter.

#

no collection needed

#

you just put a parameter name on the texture sample node in the material graph. then you call that dynamic material parameter in blueprints (after creating a dynamic material instance) and set the texture to anything you have in your assets content.

wet mountain Jun 19, 2020, 6:58 PM

okay, i'll try that method, thanks a lot @static charm and @inner ginkgo

That's a design choice where either works. Depends on how complex your pickup logic is, putting in the character code means you only write it once. But putting it in the items means you'll have an easier time customizing specific logic for each item.

@wet mountain The dynamic materials should extend to however many textures you want. You can use your array idea and store 20 mats in an array and pick the one you want out of that for assigning to the dynamic material.

inner ginkgo Jun 19, 2020, 7:36 PM

#

@chilly linden I just looked closer at your logic. You are only moving the thing up. So it'll just keep going up and up. You need to have it pick 2 points and move between them. So you'll want to record a start and end point prior to entering the timeline. Start might be the current position. End might be the current position +5 Z.

#

@waxen sorrel If you aren't simulating physics and you don't have a component like a movement component tracking speed for you, then you have to do it manually. Getting current - last position works, but you probably want to divide by the frame time so that your velocity is in seconds.

#

@zenith kindle How are you currently moving your objects that you want to slow down?

waxen sorrel Jun 19, 2020, 7:38 PM

#

divide the final ( current - last ) / Delta ?

inner ginkgo Jun 19, 2020, 7:40 PM

Yes. If you are in tick, you can just use tick time. If you aren't, you can try using Get World Delta Seconds.

@waxen sorrel So the default setup shown in most tutorials is to get the axis inputs and handle each one separately. Get X, move X. Get Y, move Y. What you will want to do is to get both values and store them. Then handle movement once in your code, like in tick. Then you can do things like clamping prior to movement handling.

#

@zenith kindle I understood that. But there's more than one way to move objects in the engine, which means there's more than one solution to your problem. How are you accomplishing movement?

tight schooner Jun 19, 2020, 7:49 PM

#

You could split the vector input & output pins on that Clamp Vector node (right click on data pin) and feed Get Input Axis X & Get Input Axis Y into the node

wet mountain Jun 19, 2020, 7:51 PM

#

@inner ginkgo thank you again, finally solved the problem 🙂

tight schooner Jun 19, 2020, 7:51 PM

#

That way it's clamping the vector length of your X input in relation to Y and vice versa

Does anyone recommend something to remove sliding when turning the character 90º?

inner ginkgo Jun 19, 2020, 7:53 PM

Do you mean the feet sliding? Or is the character position sliding?

Are you using the character movement component?

zenith kindle Jun 19, 2020, 7:54 PM

#

@inner ginkgo when the green actor is told to move to 3 it will start at 0% speed. once it reaches 1 it will be at 100% speed
when it reaches 2 it is still moving at 100% speed
as it approaches 3 the speed will drop from 100% smoothly to 0% so it doesnt over shoot 3

#

Are you using the character movement component?
@inner ginkgo Yes

zenith kindle Jun 19, 2020, 7:55 PM

#

i cannot controll how it moves or why it moves, all i have is a speed multiplyer 1.0f - 0.0f to stop it from overshooting its destination thats all i can work with

inner ginkgo Jun 19, 2020, 7:56 PM

#

@zenith iris There's a Stop Movement Immediately node that you can try to use just prior to applying the turn.

zenith iris Jun 19, 2020, 7:58 PM

#

@inner ginkgo thank you. This works, but there's the stopping animation. Any other workarounds you may suggest?

waxen sorrel Jun 19, 2020, 7:58 PM

#

@tight schooner yup it worked better than expected, @inner ginkgo yeah is a custom thing for a custom actor doing something like to that

inner ginkgo Jun 19, 2020, 7:58 PM

#

@zenith kindle If you are > x distance speed is 1.0. If you are <= x speed is lerp from 0 to 1 alpha is current distance / x.

#

@zenith iris Animation is a whole other beast. The stop node helps you solve the logic, which effectively sets the speed to 0 instantly. You'll need to change your animation BP to not key off speed, which is not my area of expertise.

zenith iris Jun 19, 2020, 8:03 PM

#

Thank you

zenith kindle Jun 19, 2020, 8:34 PM

#

@inner ginkgo thanks i never thought to use a lerp node at the end. i added the actor's top speed / acceleration to influence the final result and it all works!

Hey all! I'm trying to pause my game for a moment, say 1 second, and the unpause it. But timers don't seem to run while the game is paused. I'm really scratching my head here, any suggestions?

dense badger Jun 19, 2020, 8:50 PM

#

Heya just one more try asking if there is a way to make it so BP doesn't open a new copy of the edit tab every time I double click a function?

#

I always end up with like 50 tabs after an hour or so

inner ginkgo Jun 19, 2020, 8:55 PM

#

@dense badger I don't think there is. But if you aren't using the tabs for navigation and are just double clicking functions, is having them open really an issue?

dense badger Jun 19, 2020, 8:57 PM

#

@inner ginkgo I tend to either use find, double click node, or double-click function names about 60% of the time. I use the tabs the rest of the time but once there's 50 of them they become unreadable. I swear it didn't have this behavior a few revs back. If the tab was already open it would just focus that tab... not sure what the point of this new behavior is? Why would I want 3 copies of the same function open in different tabs?

inner ginkgo Jun 19, 2020, 8:58 PM

#

@solar sonnet I haven't played with pausing too much. But under class defaults, there's a tick section. If you expand the advanced section, there's an option to tick even when paused. See if that has an impact on your timers in the same class. If it doesn't, you might still be able to tie your pause logic to the tick in that class.

#

@dense badger Oh, that sounds like a bug. If I double click an open function, it just focuses for me in 4.25.1.

dense badger Jun 19, 2020, 9:00 PM

#

Hrrm We are on 4.24.2 at the moment I will try and repro in 4.25 vanilla

Hello all, I'm making a perk system in my RPG.. i need to get some kind of static functionality I think.. where i can just access a calculation class to see if a perk applies when certain events happen (damage dealing, damage blocking, special kinds of damage)

#

i think i saw that you can't make static blueprints or static blueprint members or functions..

#

i think i could just make an object class and then construct it and then do the calculation on it.. but it seems heavy..

#

If i have to do it in CPP i will

#

but if anyone has any insight into what im looking for.. just a way to make a bunch of static calculation functions.. takes in a float(damage), source Actor, target, Actor.. outputs a bool(applied), float (damage)

#

one of them can check to see if that guy's stamina is below half.. in which case the damage would be reduced or something

#

one could see if the source actor's speed is a certain amount and then increase the damage

inner ginkgo Jun 19, 2020, 9:27 PM

@marsh seal If you just want calculations that are accessible from anywhere, you might want a function library.

Is there a way to get the "first" element in an enumeration dynamically?

graceful forum Jun 19, 2020, 11:24 PM

#

I'm trying to load my datatable with async asset loading to reduce the time user spends on black screen. However I make the user wait on my custom splash screen until Completed pin is executed and now it takes longer than when it was stuck on the black screen. Is there anything that I should be aware of while using AsyncLoadAsset?

📎 unknown.png

inner ginkgo Jun 19, 2020, 11:51 PM

#

@graceful forum The completed pin only fires when it finishes. And since it is async, it doesn't have thread priority and may take longer. It doesn't really make much sense to use async when you have a loading screen. It is more useful for doing things at runtime when you don't want to pause the user experience.

@dense badger Enums are just numbers. Byte in BP. Casting 0 to your enum should get you the first value.

It's set to draw persistently, it has a duration of 5.0, its not drawing visually and the list of hits is empty. It calls on f9

is there a bug with them like in 4.22?

where if the start and end were identical it wouldnt call

Not sure that's a bug, but it easy to test. Just move the end a bit.

If you just want to get the overlaps of a sphere, then use SphereOverlapActors. Sphere trace is for getting collisions over a distance.

An actor for example.

Any actor would do. The widget create widget node might not need a world reference, but lots of nodes do and this basically asks you to pass in something that has a reference to the current world.

You are in an actor already

@surreal peak maybe it's\ not working because it's a "Editor Utility BP"

Most likely

#

Instead of trying to have the actor create the widget, right click the widget class in the content browser and there should be an option to 'run widget' or something.

The problem is I have to integrate the widget with the Plugin. So I am calling the blueprint (because I can't seem to find a way to call the widget itself) which in turn is creating the widget.

surreal peak Jun 20, 2020, 7:15 AM

That create widget node is for runtime though

#

Editor widgets are added through the run widget thingy or can be found somewhere in those menus at the top

Which should all be explained in the docs

#

Also not sure these widgets are able to be referenced

utility objects have some other events, like on run or something. Check the override functions. Was sometime since I used ed utils.

@pseudo tusk In case you haven‘t fixed it yet, the alpha is prettymuch the same each frame if you only multiply it by delta time but don‘t actually modify it.. deltatime won‘t change much and multiplied with a static speed variable it will simply result in a more or less static alpha value and not actually give you a smooth interpolazion between ghe two values.

How can I communicate between a widget button press and a game instance ?

On button press i want a mini tut to open, but I only want it to happen once in a session.

It currently refreshes when the player changes level, which is why I am trying to use the game instance.

@dapper cradle isn't it greyed out because it's a c++ class?

@dapper cradle in the widget you can get a node called 'get game instance' and get whatever you're trying to get from your instance from there

I need to make the game instance handle the part I circled in red

#

when the button is pressed in the widget (see arrow)

thin rapids Jun 20, 2020, 6:44 PM

#

you can make that into a custom event in the game instance, and from the widget class you can cast to the game instance(object being the 'get game instance' node) and call that custom event in the widget

dapper cradle Jun 20, 2020, 6:45 PM

When i unpacked my game i coudnt save a variable at first with the save game stuff. it works in editor but when packed it doesn't work. When should i create the save game object?

#

I did it on the construct of the mainmenu UI so you could start saving variables as soon as possible.

#

i also get this error in the save logs "[2020.06.20-19.10.34:337][431]LogStreaming: Warning: Failed to read file '../../../Game/Saved/SaveGames/Slot1.sav' error."

#

hello, anyone has experience with (H)ISMCs? in particular, removal of instances? I am getting behaviour as if indexes are getting invalidated just after three removals

#

in short, I create isntances, remember their indexes and then later I want to remove some of them, but it all goes haywire after only few removals

#

I thought it is because of indexes moving by 1 after removal, but taking it in account didnt help, in fact, it works even worse

gloomy linden Jun 20, 2020, 7:44 PM

#

@full crypt now add in between the node Does Save Game Exist

#

Or do you have it already?

#

Ah you have it, nvm then

#

Keep it up

#

@modest gulch the array updates each time something is removed iirc

full crypt Jun 20, 2020, 7:46 PM

#

I do have an issue with a replication but i doubt anyone would help me, do you know about multiplayer stuff @gloomy linden ?

gloomy linden Jun 20, 2020, 7:46 PM

#

I.e. is you have index 0 1 2 3 and you remove 0, 1 becomes 0, 2 becomes 1 etc

#

@full crypt only my own network structure, i dunno how the replicating of ue4 works. Best is to ask in #multiplayer

tight schooner Jun 20, 2020, 7:46 PM

#

That's how I observed it worked too (re: HISMCs)

gloomy linden Jun 20, 2020, 7:47 PM

#

BP arrays work different then the "normal" arrays

modest gulch Jun 20, 2020, 7:47 PM

#

Remco renzu yes, but as I said, taking it into account does not help. in fact, looking into component during play it looks as if components move existing instances into freed indexes.

gloomy linden Jun 20, 2020, 7:48 PM

#

Much easier but its also a brainfart if you have to switch between them

modest gulch Jun 20, 2020, 7:48 PM

#

at least I interpret it like that

#

it is hard to explain

gloomy linden Jun 20, 2020, 7:48 PM

#

Well yes, the array updates and empty indexes get dropped

modest gulch Jun 20, 2020, 7:48 PM

#

anyway I am sitting in test project trying to check wtf is happening

gloomy linden Jun 20, 2020, 7:49 PM

#

There is no use to keep track of the indexes of the meshes in a different array

#

They will desync fast because of that

modest gulch Jun 20, 2020, 7:49 PM

#

errrrr

#

to be clear

gloomy linden Jun 20, 2020, 7:49 PM

#

Best is to re-traceline them to get its "current" index

modest gulch Jun 20, 2020, 7:49 PM

#

I am doing this

#

📎 unknown.png

#

are you saying that Return Value is effectively useless?

gloomy linden Jun 20, 2020, 7:50 PM

#

Yes, there is no use in that other than using twice the memory for the same thing

#

No, at that point, the index is correct

modest gulch Jun 20, 2020, 7:50 PM

#

🤦‍♂️

gloomy linden Jun 20, 2020, 7:50 PM

#

But when you delete that ISM, all others get an updated index

#

So the index of that ISM will differ from what you have in that array

modest gulch Jun 20, 2020, 7:51 PM

#

well if it is incorrect in unpredictable way after removal then it is utterly useless

gloomy linden Jun 20, 2020, 7:51 PM

#

The (H)ISM are already added in an array

#

I wasted a week figuring that out

modest gulch Jun 20, 2020, 7:52 PM

#

and how do you deal with that then

gloomy linden Jun 20, 2020, 7:52 PM

#

Then i gave up tho as my idea wasnt achievable in bp :d

modest gulch Jun 20, 2020, 7:52 PM

#

if tou cannot use that index

gloomy linden Jun 20, 2020, 7:52 PM

#

Traceline

modest gulch Jun 20, 2020, 7:52 PM

#

seriously?

gloomy linden Jun 20, 2020, 7:52 PM

#

Traceline by channel for object or something

#

Yes

modest gulch Jun 20, 2020, 7:52 PM

#

oh, UE, you sometimes suck so much.

#

wait, you said in bp

gloomy linden Jun 20, 2020, 7:53 PM

#

C++ is better for that tho I think

#

Already a tiny bit faster

modest gulch Jun 20, 2020, 7:53 PM

#

I could rewrite it in C++

gloomy linden Jun 20, 2020, 7:53 PM

#

I recommend it

tight schooner Jun 20, 2020, 7:53 PM

#

You don't need to save the "add instance" output into an array because HISMCs kinda already maintain their own array of instances

📎 hismc_list.png

gloomy linden Jun 20, 2020, 7:54 PM

#

Because if you have to do traceline each tick, get the index, update the HISM, you will notice increase in frame time

modest gulch Jun 20, 2020, 7:54 PM

#

renzu but I do need some identificator of particular instance...

#

my use case is like that

gloomy linden Jun 20, 2020, 7:54 PM

#

Especially if your HISM amount get large numbers

modest gulch Jun 20, 2020, 7:54 PM

#

I spawn isntances and remember their ids

gloomy linden Jun 20, 2020, 7:54 PM

#

There are chuncks to counter that though

modest gulch Jun 20, 2020, 7:55 PM

#

then later some of those will be removed

tight schooner Jun 20, 2020, 7:55 PM

#

so if you have some external array that represents HISMC instances, when you remove an instance, you also have to remove that same index number from your external array, so that both arrays resize in tandem

#

otherwise yeah, they lose sync

modest gulch Jun 20, 2020, 7:55 PM

#

carefully selected so I need some kind of RELIABLE identificator of given instance

#

you said C++ may be better, it is because I can hold ponter to instance or something?

gloomy linden Jun 20, 2020, 7:56 PM

#

I recommend doing it in c++, there is a reason ASTRONEER didnt do it in bp either

#

Bp could be the same thing in end, but likely with many more steps

modest gulch Jun 20, 2020, 7:57 PM

#

ugh, it is so bullshit. I would like some unique identificator for every instance that wouldnt change regardless of removals etc. Is this that much to ask? ;/

gloomy linden Jun 20, 2020, 7:57 PM

#

Nah, but check first all those ISM nodes

#

Just add them in your bp and check the return values

#

And see how far you can get

tight schooner Jun 20, 2020, 7:58 PM

#

FWIW, my use case is ISM feathers that make up a winged enemy; when you shoot it, it uses "Get instances overlapping sphere" at the hit location to determine which feather was hit

#

so that way it selects a specific instance

modest gulch Jun 20, 2020, 7:59 PM

#

I already tried to take changing indexes so they are in sync with ismc but it looks like it works differently than I thought

gloomy linden Jun 20, 2020, 7:59 PM

#

Maybe its enough for your project, maybe not. But you dont shoot, you will never hit the target

#

What does FWIW mean? (Im old)

tight schooner Jun 20, 2020, 7:59 PM

#

for what it's worth

#

just giving you ideas

gloomy linden Jun 20, 2020, 7:59 PM

#

well, I would like to avoid traces and other sillness

if you need a way to determine "which instance ID is this?" in your game world

modest gulch Jun 20, 2020, 8:00 PM

#

I already know which isntances I wamnt to remove

gloomy linden Jun 20, 2020, 8:00 PM

The key is to traceline when you need too

(Avoid Event Tick as much as possible)

modest gulch Jun 20, 2020, 8:02 PM

#

robin order is unpredicatble

#

so I can't

#

some instances may be removed first other last in different time

#

depending on player actions

#

so yeah.

tight schooner Jun 20, 2020, 8:05 PM

#

If your HISMC doesn't have to update that much then you can do a brute force approach where you don't care about the preexisting instances; instead you use your external array variables or whatever to drive it

#

every time you need to update the instances, clear all the instances and remake them again

#

not very elegant but depending on your use case (number of instances, average frequency of updates) you could get away with it

modest gulch Jun 20, 2020, 8:08 PM

#

thats absolutely out of question, unfortunately

#

while deletion should be rare, there are thousands of instances

tight schooner Jun 20, 2020, 8:08 PM

#

yeah, thousands of BP node executions to update the HISMC...

modest gulch Jun 20, 2020, 8:09 PM

#

I already was forced to spread out spawning new areas (in background) over many ticks to have acceptable framerate 😛

#

(my game is basically procedurally generated labirynth)

#

and in my experience UE is pretty unfriendly for procedural generation, but that's different topic...

tight schooner Jun 20, 2020, 8:11 PM

#

In my winged enemy, I also use this node. (I have externally managed arrays of transforms for interpolation purposes.)

📎 feathers.png

#

So that's another way to not-care about which instance is which

modest gulch Jun 20, 2020, 8:12 PM

#

my instances are static

#

they are walls, floors, ceilings and other objects in game area. whole deletion thing is used to things like secret passages or hiding areas further away generating in background

#

idea is that if player turns away or is far away then walls are removed

#

so he never sees areas generated on fly, breaking game immersion

#

and yes, having no walls where there were walls previously is more than acceptable

#

this is suspense/horror game full of slightly unnatural elements so in fact this will add to atmosphere 😉

#

anyway thanks for help, I will try to deal with it. somehow...

cedar sparrow Jun 20, 2020, 8:28 PM

anyone know if there is a way to do an 'input held down' without using tick?

maiden wadi Jun 20, 2020, 9:17 PM

#

I'm having a very odd, small issue. I have a drag/drop set up. Everything works great except one small part. I have a macro that takes in key presses both press and released and sets bools based on which key was pressed released and sets an enum as well. For some odd reason, if I open my userwidget with the dragdrop and then press one of these modifier keys, the first time I start a dragdrop it seems to call 'release' on all of my modifier keys. After that first time it's running perfect, until I close and reopen the userwidget. The Widget is in focus. Nothing seems to stop that very first drag/drop from causing all of my inputs to 'release' Every following drag drop when done in the exact same manner works as intended, just not the first. This includes dragging and dropping the first time where nothing would change, which means no code is being ran that could possible change this and yet the second drag will work smoothly. Clicking the buttons before hand is no use. I'm utterly confounded by this.

flint nymph Jun 20, 2020, 9:28 PM

@woven saddle you’ll want to multiply something by 1/time dilation. Maybe your input mouse axis values for the camera controls or maybe the player controller time dilation it all depends on your camera setup

#

I’m sure there are plenty of ways to approach it though

#

also this node but I’ve never used it https://docs.unrealengine.com/en-US/BlueprintAPI/Components/Timeline/SetIgnoreTimeDilation/index.html

looks like that node is specifically for timelines tho

woven saddle Jun 20, 2020, 9:34 PM

#

yeah it's just the camera I want to ignore, I want the player to be slowed down too

flint nymph Jun 20, 2020, 9:38 PM

#

yeah then maybe try multiplying the input axis values for controller pitch and yaw

woven saddle Jun 20, 2020, 9:40 PM

#

multiply by 1 yh?

flint nymph Jun 20, 2020, 9:41 PM

#

multiply the axis values by 1/time dilation

#

so if you’re setting time dilation to .25 it’ll multiply the inputs by 4

#

hm it's a bit wonky but it might be my setup

@shy palm Just open up the files in visual studio or whatever editor and search for the node name without spaces. In this case, AddMovementInput comes from Pawn class, so you'll want to look in Pawn.cpp for that.

Finally got it working: My exit function had to be placed inside the Widget; doesn't work if its only in the Player. Strangely: I tried setting Input mode to Game and UI but it still couldn't work.

#

For my next trick I'll get so that I don't have to use the mouse in order to start using the keyboard/gamepad on the menu

guys? can i somehow use input key in construction script to change values on press? thanks for help

You won’t be able to use input during the construction script. @gray fox

#

@trim matrix so i cant even controll what is in construction script with event graph?

#

thing is that i set up actor relative scale 3D on damage object i can controll it in level bp but sim is not correct on hit, it works only in construction script where is generates random scale and works correctly, but thing is that i want to change scale in game

@gray fox The construction script is a single function that gets executed when you change any properties on the actor. It only happens while you are in the editor as well. It will not be executed during runtime.

like generate it again

trim matrix Jun 21, 2020, 12:43 AM

#

So you are using the construction script to change it’s scale? But you want to be able to also change its scale during gameplay?

#

You might want to put that functionality for that into a custom event or function.

#

this is correct with construction script

#

and this is exactly same bp but in event graph

I’m confused on what exactly your trying todo

gray fox Jun 21, 2020, 12:49 AM

#

i am trying to do what is on first image (without levitating) but binding it on input key in event graph does not work, it gives that weird error (second pic)

I'm struggling to figure out how I can do this. I have an inventory system, where I'm able to store various types of world objects, like trees and houses. And I want to be able to place those objects into the world. Like a building system, but for specific pre-built meshes.

trim matrix Jun 21, 2020, 12:50 AM

#

Oh ok. So your input is in the level bp right?

gray fox Jun 21, 2020, 12:50 AM

#

this is bp for scaling

#

table is actor

#

i dunno its probably some type of scaling issue, i tried different types but same result after sim is running it gets weirdly stuck and levitate

#

unless its done in actors construction script

trim matrix Jun 21, 2020, 12:52 AM

#

It’s an issue with how your getting the random scale from your array

#

You want to pick one of those entry’s in your array to be its scale randomly right?

gray fox Jun 21, 2020, 12:53 AM

#

yup

#

even better would be to be random and different than previous one
