blueprint

[sonic crow]

when you say after I spawn the bomb, do you mean after my private function inside of TopDownCharacterBP i pull out the Execute triangle, create a float function...last thing I am still not sure how to create the target. Also now I need to address two inputs?

should i promote the target in the image to a variable?

[faint pasture]

Promote the output of the spawn actor node to a variable

Are you following what I'm trying to have you do at all?

[sonic crow]

that makes sense you want me to create a reference for where the bomb spawns from

i think i got it

[faint pasture]

No, i want you to make a reference to the actual bomb

so then you can tell it the direction to explode in

but anyways i gotta go, good luck

[sonic crow]

thank you

you are a legend it works

[gusty cypress]

Yea I'm so lost it didnt work but every number I fed it was rounded so?

split times add up to 26.108 final time was 26.111 (ignore the 18.104 thats level record)

[brazen merlin]

can i see the bp graph?

[gusty cypress]

yea 1 sec

timer

end time (display) and math

wait this is the in game timer display

[brazen merlin]

question, do you need the float or the text or both?

as in, to be used elsewhere than just to show the player

[gusty cypress]

float for math text for display (to see if the split times/final times are slower or faster then float to display it so its readable format 00.00.000)

[brazen merlin]

well, i mean i see the leaderboard on the right, that's updated somehow too right?

[gusty cypress]

yea trying to find that spaghetti

so the split time is set depending on what level your on shown here

[brazen merlin]

and is this a mp game?

[gusty cypress]

wait trying to find how current split time is set

Here we go

[brazen merlin]

If you want to take large screenshots of the bp that aren't tiny blurred images >>https://www.unrealengine.com/marketplace/en-US/product/blueprint-graph-screenshot

[gusty cypress]

This works as if your on stage 2 and time is 10 secs and stage 1 was 6 secs it subtracts that giving stage 2 a time of 4 seconds since it will always add up to total

it even works for first stage since previous stage doesn't exist so its total time - 0 which works fine

[brazen merlin]

hang on, brb

Hmmm so theres this tiny 0.03 discrepency but otherwise everything works as you intend?

Would this also be the same when tested in standalone?

[gusty cypress]

the discrepancy is different every time but very minor this is why I believe its a rounding error

[brazen merlin]

I was thinking it was a tick thing, not being true to framerate

this is editor after all, not accurate of true framrate

[gusty cypress]

yes but what confuses me is the in game timer and split times should both be being fed the exact same values to do the calculations

[brazen merlin]

so, about that

[solar dawn]

hey guys, level bp stops working after my level encounter starts. anyone knows what happens?

[brazen merlin]

here's how i read it

[brazen merlin]

not enough info

[solar dawn]

gimme a sec, snapping

[brazen merlin]

I see you have the StartTimerEvent, this is calling GetGameTime, then after the gate it calls it again. This is based on tick firing and when it is opened

Game time should be the same, but its on Tick's repeated call, which could differ as startTimerEvent accesses game time, then opens the gate, Tick fires thereafter

I would be under the assumption that it should happen in one frame though

[gusty cypress]

so should I not be using an event tick?

[brazen merlin]

so, without having you tear this all down, i think testing it standalone would be easiest to verify my assumption

[solar dawn]

hope u guys can see it

[brazen merlin]

uh, i see them all fire, are they suppose to keep firing?

[gusty cypress]

ill package now but still unsure what your saying, I should rethink or even remove this whole gate system I have?

[brazen merlin]

i dont know 😛 its a hunch since everything else is working that ive seen

if the average difference between times is around 0.03, then im looking at tick, even though its quite a large chunk in regard to tick rate

[solar dawn]

I thought they supposed to keep firing

[gusty cypress]

When I get the time float I round it and I when I print its not rounded but its so minor I think its the engine just being weird

it adds .000001 so its like whatever just interesting since I round it at .001

[brazen merlin]

they could, depends on how you call them. All I see is some lines being fired. Is the even plugged into the sequence Begin Player or what?

[brazen merlin]

floating point precision shouldn't be that noticeable though

.000001 yes, but not .01 or .001

keep testing it though, maybe a pattern emerges

[solar dawn]

Event BeginPlay -> Sequence

[brazen merlin]

that will only fire once, as it states, at the begin of play starting

[last abyss]

it just seems like a math error to me, on the end result you have the total time spend in the event rounded while in the splits you're rounding it up or down on every split, so wouldn't you naturally get a different result from adding the split times vs the total time

[solar dawn]

okay but do u take this as normal??

[gusty cypress]

could it be since everythings not happening at the exact same time that's why the math comes out different

[brazen merlin]

no I don't, but I've not used timers to run that long, though by its function it should keep going

[gusty cypress]

bc here I print 15.242 ... the timer says 15.242 ... but now the in game final time display is 15.241?? it happens after how is it a lower time? first I pause time then I set final display

I did not expect time to be this hard

[brazen merlin]

now that that is odder

in reading that forum post a little closer, it seems converting the time float to an int or text is more accurate

[gusty cypress]

once in text can I do math or do I have to convert it back

[brazen merlin]

maybe float to string to float would be better

ive not done this kind of accuracy with floats/time so personally, i would use integers

in any form it still seems like it will not be accurate

[gusty cypress]

Im not worried about accuracy I just want the split times to match up with the final time

ill try the float to string to float

[brazen merlin]

i did have a different notion

seems just as unknown though

[gusty cypress]

Im interested

[brazen merlin]

make it a pure function, since it is performed for Old Time and New Time

for the gate

To me, that may look it up as the same value, and this is on the assumption that this is where the discrepancy is happening

to know exactly where the difference is happening then it might be easier to discern

[gusty cypress]

is this what you mean by pure function

[brazen merlin]

ah, sorry, yes its made like a function like anything else. give it the output and all that

on the function itself (select the function) there is a pure checkbox

[faint badge]

In one frame doesn't mean it'll be the same value as that node gets the exact time when you call it so it's totally possible there's a small discrepency between repeated calls even on the same frame.

Also depending on how you're calculating the split totals you could run into issues as float math is not exact and every operation you do introduces some small error, if you repeat that the errors can compound. So for example repeatedly adding your split times may not give the exact same value of just subtracting your start time from your final end time. See https://0.30000000000000004.com/ for a good example of what's going on there

[faint badge]

That is not true. Pure functions do not cache values and will be called once for every time you read from an output pin. Never rely on having two things connected to the same pure node being the same value. For example the random node, if you have two prints connected to the same random node you'll get two different values printed.

[brazen merlin]

Yep and Yep, I stated this as well

[faint badge]

Ah sorry, I came in late so I may have missed that. Anything involving floats is definitely tricky to get right sadly

[brazen merlin]

said it here: #blueprint message don't think its so clear though

nah its good to reiterate

i would think to set a variable to then use so it is the right value, but this sutuation doesnt allow that

[gusty cypress]

I'll try the function with the pure true and see if it changes

[brazen merlin]

and if the pure function doesnt change it, which is a reach, then maybe keep it a float for as long as possible and convert just the one time it needs to be

this, i assume, could be with the CurrentSplitTimerNEW

Though.. #blueprint message

[faint badge]

Ah, It's one of the things I dislike with discord, if you join a conversation late it can be very hard to track, especially as it starts getting mixed with other messages

[brazen merlin]

still doesnt seem like any way around it though

[gusty cypress]

Okay noob question how can I use an integer to get decimals?

[brazen merlin]

oh your all good, not a worry, this has been a long solve in a topic that i didn't want to jump to about float inaccuracy

[brazen merlin]

just to preface, this may still be as inaccurate as it is currently. but its close to what you're doing already. GetGameTimeInSeconds x 1000 (or whatever) convert to float via truncate or such

again, this still does not quite get around floating point precision though

so, basically, 30 minutes ago, GO TEST THE STANDALONE

[gusty cypress]

I'll do that now

[brazen merlin]

thank you

id hope its more accurate if anything, even if still a bit off

wait didnt you test standalone actually?

[gusty cypress]

Confused float inaccuracy is such an issue when so many other games (every racing game) .001 precise split times and in game times which align

[brazen merlin]

well.........

programming may have some extra tools that bp does not

they could write the entire thing with ints for the sake of accuracy

[gusty cypress]

Thank you so much, even If I can't figure this out right now I've learned a lot, Im gonna sleep while it packages considering baking lighting for just 1 level takes nearly half a day

[brazen merlin]

yep, learning is important

[faint badge]

float IS float32 on modern systems

the 32 just specifies the number of bits (effectively how much memory it takes to store the number, which also determines how accurate it can be)

float on modern systems is set to be 32 bits and double is 64 bits. In UE5 we'll have support for double in BP which will give you more accuracy in floating point calculations

[icy dragon]

Spoiler alert:
||60 FPS = 16 ms/ frame = 0.016 s / frame||
||120 FPS = 8 ms/ frame = 0.008 s / frame||
||Given the common frame times are not even less than or equal to 1 ms, and Unreal waits for a frame to be fully finished, you're exercising in futility at that accuracy.||

I think a lot of racing games went for fixed frametime rate, e.g. only logging the record in multiply of 16 ms or 8 ms.

[brazen merlin]

thanks for the correction, i was thinking of int

[brazen merlin]

that is a good note about racing games being frame limited. still wondering about dropped frames and how that would get solved, but im also not making anything with such precision (not yet!)

starting to wonder how effective it would be to use tick delta for counting frame/sec but im pretty sure that what get game time does already, and specifically when game starts too

[faint badge]

Same thing, int is the same as int32 on modern platforms, although a lot of coding standards now prefer you to explicitly specify the bits to there's no confusion when someone else reads your code about how big something is

[brazen merlin]

damn, im blowing it, i was getting int and int64 confused - with float and with int32!

[icy dragon]

Though it's more of my educated assumption. You'd definitely had to analyse a lot of tool assisted speedruns of racing games directly by playing the recorded input and tamper a frame or two to get a more conclusive result.

[brazen merlin]

i bet the info is out there if i looked for it, no motivation to do so now

[faint badge]

Hah no worries, having types not specify their size definitely makes things confusing. I know of one platform where bools are two bytes for example which caused chaos for code that assume it was only one 😦

[icy dragon]

Besides, I'd argue that losing to 1 ms inaccuracy is super astronomical.

One trick that I've been thinking is to switch the time value from the paused real-time to the stored one upon finish.

[brazen merlin]

code is my kryptonite, its showing, memorization to that degree is just that extra layer. like a character build, i opted for that skill and put points into art

[quick kettle]

hey ya, i have a question. i need to use blueprint to control some actors depend on a work flow. some of the actors need to move or do some operation sequentially, and others need to do the same tings in parallel. how can i implement such feature? do i need multithreading?

[brazen merlin]

feel free to think on the idea more, i gotta move on

[faint badge]

Totally understandable! There's so many different things that go into games it's completely unreasonable to expect any one person to know it all. I only know my own little bit of stuff and definitely have to rely on others for a lot of different tasks

I think my most frequent reply in #cpp when people ask me a question is some variation of "That's not an area I know about, sorry"

[icy dragon]

Actors doing something is going to add up to the Game thread frametime. Unreal will finish all the stuff that supposed to happen in that particular frame before moving on to the next.

[brazen merlin]

ah for sure, but hey if no one else is responding, why not give it a shot?

[faint badge]

For most people, definitely! Always good to try to help. Sadly because I work at Epic if I am not sure about something and say something incorrect people treat it as an official answer which can cause more issues

[icy dragon]

I think if anyting, MTing would just even out the tasks, possibly reducing the frame time. Though I don't think BPs are capable of MTing to begin with

[brazen merlin]

ah damn, yeah, you've got some liability there

[faint badge]

Though I don't think BPs are capable of MTing to begin with

They are not and in fact it is not safe to interact with any Unreal Object outside of the main thread. You can still do multiple things on the same frame which will appear to a user like they happened at once but really they'd be calculated sequentially. Considering a user only sees updates when a frame changes, doing multiple things on the same frame will have the appearance of it happening in parallel

[quick kettle]

thank you first, i think i understand you. probably i need to use cpp. what i'm doing now is creating a work flow, just like a production line in a factory. i need to control actors to finish some operations in sequence or in parallel.

[icy dragon]

If the frametime impact on Game thread is not that high, you could get away with single threaded BP, no MTing necessary.

Though that being said, if your BP logic does impact the Game thread that bad, just try translating the function in C++ so that it runs on C++ speed, and still no MTing involved.

[timber knoll]

Was about to say the same

C++ isn’t as daunting as people say it is

Especially if you’re just translating from BP

Rule 1: don’t optimize

[icy dragon]

Yeah, considering a lot of built in BP functions are callable in C++ through Kismet function libs (just that you'd prepare for lengthy function names), and stuff like asset loading (which is PITA to do in C++) can still be outsourced to BP for the ease of use without taking much BP overhead.

[timber knoll]

Yeah exactly if you just expose some data to BP but your logic is in C++ you will still benefit the performance

But regardless you should always follow rule 1 of optimisation

Don’t optimize.

[brazen merlin]

regarding bp and cpp, ive tried the bp nativization on packaging but i hadn't notice a difference in framrate and there is a lot of bp being used

[timber knoll]

It really depends what you’re trying to do

In many scenarios your framerate will be depending on GPU not CPU

[brazen merlin]

i tried it thinking it would be better seeing that the preference on performance is cpp

[icy dragon]

The difference is pretty tangible IMO, but because it's basically machine trying to reverse engineer BP without love, it's not as optimised as manual translation.

[brazen merlin]

i kinda figured as much, it also did not work on some bps (i think because they used structs?) Maybe one day ill optimize things in cpp

[timber knoll]

Have you compared actual stats? Or just framerate?

[brazen merlin]

just framerate, so yeah i getcha

[timber knoll]

Because cpu load and time should be different

[quick kettle]

good! by the way, where do you think is the best position to write the main control logic, which will control the work flow, like sending some signal to tell the actors begin to operation. level blueprint? or an controller actor customize by myself?

[brazen merlin]

i felt no difference when playing the game, which means i dont need to profile to great length 😅

[timber knoll]

Nah don’t use level BP

If you want level specific logic, you should probably have it in gamemode instead

And just have more gamemodes

[icy dragon]

I think anything but level BP is more acceptable.

[brazen merlin]

its unfortunate how many tutorials show things in level bp.. it should just not exist

[icy dragon]

In fact, my own rule is not to use level BP at all times (mainly due to open world necessity)

[timber knoll]

Completely agree 👍

Yeah I just make child GM blueprints instead

[quick kettle]

thank you for all of you, you guys really give me a lot of advice!

[dapper bobcat]

The Level blueprint is nice to use for debugging at times, but yeah avoid actual game logic in there

[brazen merlin]

its weird like that isnt it? its like, are you new? use the level bp and then you learn never to use it, like... wtf

im comfortable just making a bp class and tossing it in, but thats me

i feel its a remnant from udk days where kismet was only level bp

[dapper bobcat]

Using the level bp might actually be easier for beginners, but it’s not best practice and that should be explained in tutorials that utilize it when you maybe shouldn’t

[timber knoll]

There are some use cases...

[dapper bobcat]

I can see how just putting everything in the level bp to make your logic work can be encouraging and easier for beginners

[dapper bobcat]

Yeah for sure

[timber knoll]

Such as tutorial triggers that are completly level depending anyway

But not much more besides that

[brazen merlin]

easier yes, but still possible without

[timber knoll]

Well anything is possible without the engine structure haha

You should always make your life easiest

[brazen merlin]

by that logic i would retain the fact to never use level bp then 😆

[dapper bobcat]

Generally speaking though, the level blueprint isn’t too useful. More for prototyping, debugging and perhaps some one off logic.

[brazen merlin]

what's easy right now vs down the road

[timber knoll]

If you’re like me, down the road will include rewriting everything 4x hahaha

[brazen merlin]

yes, programmers call that refactoring so they sound like they know what they're doing 😁

[timber knoll]

Hey!

I do know what I’m doing... sometimes 🤔

[icy dragon]

Heh. Don't remind me of myself refactoring my own tools 😉

[timber knoll]

I think artists are worse in that case, they don’t refactor

But they change their mind 10x

[brazen merlin]

they could be neater 😛

[timber knoll]

Which makes programmers have to make changes 10x

😅

[brazen merlin]

dont put in art in a box 🙂 they have enough to deal with when they don't know what they're doing until you ask them what it is... we'll say it was planned all along

no one is safe! it's all anarchy in game dev

[timber knoll]

Yeah I can only talk about student game artists

When you’re almost done with making it all work they go like: “wouldn’t it be nice for this to do that”

😔

[brazen merlin]

yeah, gotta have some professional background to realize its better to complete an idea than to never decide on one

thats discipline right there

contradictory to what most artists want

[timber knoll]

I’m guilty!

Altho not an artist... trying to make a full game has been a lot of back and forth

But you learn along the way...

A lot of leaving “dreams” behind and just making it very simple to begin with is the key

[brazen merlin]

yes it is! tis why i avoid cpp, it would be another avenue to change my mind in, ill stick with..... design, bp, art, animation, vfx, sfx, data tables

i think the list goes on but yeah, many hats right?

[timber knoll]

Haha for aure

[brazen merlin]

thats normal and its good to get use to

[timber knoll]

I got in to C++ for my project, just as an extra challenge

But I’ve been learning the language in uni anyway so

[brazen merlin]

too cool for me

[timber knoll]

I might be overscoping a little with added multiplayer...

Considering how many other things I still have to learn about animations and vfx 😅

[brazen merlin]

oh geez, just pile it on

[timber knoll]

But oh well for such a simple game, making it MP isn’t that hard and I wanted to learn it at some point anyway

Might as well start simple

[brazen merlin]

anyways, yeah you know... blueprint performance is a riddle, that framerate... mp with bp, tricky huh?

[timber knoll]

For sure possible to make most games if not AAA work in BPs only

Mp that’s something else...

Can’t even get Steam to work without custom C++ code in 4.27

[brazen merlin]

can you think of any mostly bp AAA games? fortnite?

[timber knoll]

Don’t think there would be any really...

They all have experienced C++ programmers

[brazen merlin]

but all the books!

[timber knoll]

There are fairly big BP games tho

[brazen merlin]

right on

anyways, just trying to keep on topic with the channel

[timber knoll]

Haha don’t worry I’m done ranting 😂

Best of luck with your project, I should get to work

[brazen merlin]

ah right, same to you

im off to bed actually

[timber knoll]

Goodnight in that case

[crimson jolt]

Either I've discovered an engine bug or I'm doing something wrong. It seems like the SceneCapture2D component's "Show Only Component" node isn't working with Niagara components.

Steps to reproduce:

• Add SceneCapture2D component to BP
• Assign a RT Texture Target, set Render Mode to "Use ShowOnly List", Source "Final Color", turn off all Show Flags except Particle Sprites, Static Meshes and Translucency
• At Begin Play, execute Show Only Component with target as the SceneCapture and In Component as the Niagara Component (if this is changed to a static mesh it works).

[thorn ermine]

was there a question here? 😆 or you just want to show an internet connectivity issue?

[gritty aspen]

i just want a solution

[thorn ermine]

Ok, for whatever reason, your editor believes it is unable to connect to epic games data collection endpoint. it is just a warning and has no impact on your game.
if you have a specific issue with your project you can ask here as well, but that is just a warning and has nothing to do with your project. 🙂

[gritty aspen]

ok solved

[vivid sleet]

i need help with something, i converted some meshes into blueprint actor and when i try to save all, the level doesnt save, what could be the problem ?

[atomic salmon]

@vivid sleethttps://answers.unrealengine.com/questions/1000387/cant-save-map-graph-is-linked-to-private-objects-i-1.html

Maybe make a full backup before attempting the fix.

Just to make sure.

[vivid sleet]

i fixed it, the problem was the blueprint i recently made didnt get included in the level somehow,

[desert relic]

Guys im having problems setting up a multiplayer game

I cannot posses a character in client

[flint warren]

When I bind a button's "Is Enabled" to a function, and it gets disabled, it looks like this and is still clickable

but if instead I call Set Is Enabled with false, it looks like this and ISN'T clickable

what gives?

(is this an Unreal bug or am I doing something wrong?)

for reference, when the button is enabled it looks like this

[vivid sleet]

@atomic salmon it didnt work for me

[atomic salmon]

But you fixed it right?

[atomic salmon]

#multiplayer but be more specific about what doesn’t work and show some of your code

[vivid sleet]

i fixed it by deleting the blueprint that i just made

once i convert the sofa as a blueprint actor, it does the same error

is that normal ?

[atomic salmon]

Errors are never normal. It may depends on how it was imported. Maybe you can try to reimport or try a different import method if feasible?

[vivid sleet]

i imported it by datasmith

question, doesnt making copies from the object of the same object then coverting them into blueprints produce this error ?

bcuz at first, i imported 1 sofa, then i coppied it and converted them both into blueprint actor

[atomic salmon]

Q: Is there a way to clear the datasmith user data or remedy this problem?

(I figured out the solution to this shortly after posting)

A: There is an “Asset user data” category at the bottom of the object’s detail panel, clearing the datasmith user data asset from this has solved the error and allowed the object to save.

[vivid sleet]

will that make the objects as static mesh componants ?

[atomic salmon]

If the clears the error then you can try converting it to BP

I guess you need to be able to interact with the object?

[vivid sleet]

i just want to change the materials of it by widget BP

[atomic salmon]

Then yes, usually through a dynamic material instance

[vivid sleet]

hmm, okay

thanks for the help

🙂

[open walrus]

I've got a little puzzle I need to solve for my game. I posted yesterday about the weapon attacks being too quick for a basic trace to work, so I needed to find a different solution.
The solution I've found so far is to do a sphere trace based on the maximum range of the weapon. This consistently hits enemies, but obviously it can't distinguish between enemies that are in range of the swipe, and enemies that are behind the player.
I have it saving the position of the weapon in the last frame so I should be able to test whether the enemy is between the two angles, but I'm still working out a way to do it consistently, so far it only works most of the time. Does anyone have any suggestions?
Apologies for the terrible example drawing BTW 😛

So in this example it would need to register a hit on the top enemy because it's between the two weapon positions, but not the lower enemy.

[timber knoll]

Dot products my friend

[atomic salmon]

^^^ that

[open walrus]

Thanks, I'll look into that.

[timber knoll]

that will give you the cos value of the angle between two vectors

[atomic salmon]

Consider the weapon positions as vector and do a dot product with the vector from the player to the enemy

If the sign of the result is positive the enemy is in front of you

[thick dirge]

just a quick question... when i play animMotage for death. how do i stop ai standing back up into idle pose after it completes?

[timber knoll]

have you tried to disable auto blend on your montage?

you could also freeze/pause the last frame or just disable all animations on the mesh in general

[thick dirge]

🙂 i didnt know i could disable animations, thank you

[desert relic]

is this how spawning and possesing in multiplayer should look like

[silk cosmos]

#multiplayer

[desert relic]

bruh no one is answering there

[silk cosmos]

And no one is guaranteed to answer, but you're more likely to get a response if you ask in the correct channel. The game mode has an easy system for respawning players. Why don't you just look up tutorials

[icy dragon]

Be patient.
Hours after response is like the normal luck you can get.

[desert relic]

well i did for 5h

[silk cosmos]

@desert relic this is the process I have set up for one of my older projects

[desert relic]

yeah but u didnt use "posses"\

[silk cosmos]

😐

The game mode has a built in function called restart player at player start, which takes in said player, and said player start. It handles all the spawning and possessing

[desert relic]

oh

do you need to use authority for it

[silk cosmos]

No. The game mode is server side only. So every thing done on the game mode is done on the server. The cast to the game mode will fail unless the cast is done by the server

[desert relic]

well im trying to make mine for on the client too

[silk cosmos]

? It also respawns clients

[desert relic]

bruh how

ok im gonna try to make it myself

[ancient atlas]

I am trying to play a sound whenever my enemy moves but it isnt working. Is there something here which isnt correct thanks

[silk cosmos]

Create an event and plug it into set is moving. Off the begin play use set timer by event, plug the event you just made into the timer, and set a delay on the timer

[atomic salmon]

@ancient atlasEvent Being Play is executed only once, at the beginning of the game (when you start playing). After that it is not longer triggered. If you need to constantly check if you enemy is moving, either use a timer as suggested or use the Event Tick which fires at each frame

The best would be to delegate that to the enemy blueprint itself, so when the enemy moves it will trigger its own sound

[silk cosmos]

Event tick in this case wouldn't make sense, because you don't want a sound to play each frame. You could set a delay, but generally you should clear your tick event from code as trivial as this

[ancient atlas]

i hooked it up to event tick before but it still didnt play, i will try the other way

[atomic salmon]

@silk cosmoscorrect, I should have been more complete in my answer. In that case one would check if the sound is already playing and not play it again.

Same problem with a timer though. You would need to know how long the sound lasts or still check if it is already playing.

@ancient atlasin that case you would need to check your logic and also ensure the sound is not triggered again if it is already playing

[ancient atlas]

i also tried to add the sound to the actual run animation but i couldnt get it to trigger

[atomic salmon]

You would need to use animation notifies for that

Do some basic debugging to your blueprint

Use Print String to check when something is executed and write a message on the screen

@ancient atlas ^^^^

print strings are my friend 🙂

[desert relic]

how do i replicate everything from server to client or vice versa

[fiery glen]

read the pins in #multiplayer

[tawdry surge]

Do on clicked events not replicate properly?

Still working on 3d widgets and someone said they had to use on pressed instead to get it working

[trim matrix]

why do people abuse blueprints

[tawdry surge]

Personally I like to prototype in BP and then transfer.
I find it way easier for debugging and iteration, plus it's easier to visualize the flow of the logic

[vivid sleet]

where can i find the " asset user data " ?

[trim matrix]

transfer to cpp?

[fiery glen]

he probably means convert by hand

and yeah C++ is too slow to prototype on

[tawdry surge]

[woven wing]

Unless you're really into watching things compile.

[mild shell]

is there a way to temporarily disable all physics in the world instead of looping trough all actor and manually disabling it?

[faint rivet]

how to replace that Jump Asset when i have a custom jump function (it didnt worked so i just created my own, and actually want to keep it now :))

that Screenshot is from the 3rd Person template State Machine, from JumpOut to Idle again

like what does this function

[warm rock]

Little question, do umg tooltips work on 5.0?

[odd ember]

perhaps better asked in the UE5 section of the discord

[odd ember]

that's animation state transitions, #animation

[faint rivet]

nobody anwsered there and i thought this function might be used in other cases too

[odd ember]

no it's purely animation based

[warped spindle]

Hey. Can anyone help me with a save game problem.
I made a currency in game.
I win coins in game so I put the coins in the player BP then i reference the save game and set the coins i won from BP player to save game.
So when i go to menu to use them. In bp menu widget they are not there.
I've set already in widget to show me the coins saved in SAVE game and they are not saved. I don't know what to do anymore. All other things are saved like unlocked level

[maiden wadi]

By coins, do you mean an integer, or actual objects?

[warped spindle]

INT

[maiden wadi]

Would need to see the saving and loading code then.

[warped spindle]

Yeah.. but all the other things are saved ,just the coins aren't saved. Could be a bug?

[maiden wadi]

It's unlikely a bug. Unless you're using UE5.

[warped spindle]

I tried to see the problem with print string and then the level is done the coins are changing like it should be ,but when i change the level in this case the menu level that number is not saved

UE 4.27.1

[spark steppe]

show your save/load stuff

[maiden wadi]

Can't help without seeing literal logic. 🤷‍♂️

Best anyone can do before that is to tell you to make sure you plugged the thingy into the other thingy that does the thingy with the thingy.

[spark steppe]

make sure you plugged the thingy into the other thingy that does the thingy with the thingy.

[maiden wadi]

^

[spark steppe]

you wish^ (and so do i)

[dreamy ice]

is the only way to delete an object is to remove all references and wait for it to be collected?

[maiden wadi]

Pretty much. At least in Blueprint.

[dreamy ice]

thats painful

[maiden wadi]

O.o Why?

[dreamy ice]

I built it with many references in many different blueprints and now I have to change how ive written the system

[maiden wadi]

Wait. What?

Filetype reliance is very different than garbage collection.

[warped spindle]

The first is Menu WIDGET ,second level BP to save every time the level is complete , the third is in the player BP

[dreamy ice]

actually does it include references to something within the object?

[maiden wadi]

@warped spindle I don't know where that long blue line is going. Where are you setting SaveGame1Ref? Both in the Level and the Widget

[warped spindle]

Just to save game slot

[maiden wadi]

What about the SaveGame1Ref?

[warped spindle]

It's the save game reference

[maiden wadi]

But where are you getting it from?

[warped spindle]

To set coins

To get the coins in save game and change them with the coins collected trough level

[dreamy ice]

I meannnnnn how many objects would be performance dropping? they're all very time logic wise.

[maiden wadi]

Right. But where are you setting the reference at? That is just a pointer. Have you actually loaded a savegame and set the return to that pointer? I'm assuming initially that is what you need to do right after LoadGameFromSlot.

[shy plover]

If i have radial force in my character bp will it affect the charracter in game ?

[odd ember]

depends on the objects. not all objects are created equal

[warped spindle]

The reference is made like that.
It's the same in others BP to get the reference to save game.

[maiden wadi]

How does it get from HUD to the level blueprint?

[warped spindle]

I made the reference is level BP too

[maiden wadi]

Made or set? Because just making the variable creates an empty pointer for an object of that type. It'll be empty/null until you set it to a valid object.

[warped spindle]

No. It's made exactly like in the image before.

[maiden wadi]

Then you haven't set the variable to anything.

[warped spindle]

The thing that's not working is that Int after i change the level.
The bool highlighted it's working perfectly and it's saved in save game.

[maiden wadi]

Then you have to be setting that variable somewhere in your level.

It won't just work by naming them the same thing in the HUD and the Level and you're setting it in HUD.

[haughty nymph]

how can i make a exec line to my location vector

[warped spindle]

I remembered that a simple blueprint can't communicate with Level BP directly. That was the problem. I solved connecting the player with the save game and then with widget menu. Thanks anyway for support
https://c.tenor.com/RegpKvUKWgMAAAAM/boom-explosion.gif

[odd ember]

level BP can communicate with actors in BP?

although level BP should not house logic that is systemic

[warped spindle]

Actor that exist in the level you can comunicate with them trough level BP ,but if they aren't exist in an other level you can't communicate with them.

[odd ember]

yeah level BP goes for the level you are in currently it should go without saying

[sage magnet]

Hello everyone,
I'm trying to figure out how to make a crank in VR. Anyone had experience with this or can share resources?

(research resources)

[odd ember]

have you tried #virtual-reality ?

[sage magnet]

whoops 🙂

[spring bramble]

Hey im currently setting up a system for being able to throw/drop an object and on hitting the floor it activates a game over.( the object being thrown is simulating physics but when it is being held it is not simulating physics) when it hits the floor after being thrown it doesn't trigger the overlap but while holding the object it triggers the overlap is there any way to trigger overlap events on objects that are simulating physics or another way creating the system that could fix this issue altogether? thanks in advance 😋

[haughty nymph]

i mean that yellow position thing if you want to spawn

[timber knoll]

lorash is trying to say a vector is just data, you can't execute data

[odd ember]

why don't you trigger the game over on the Event Hit?

[spring bramble]

I did try a On component hit instead but it doesnt trigger in either situation for some reason 😅

[odd ember]

on which actor are you doing this?

[spring bramble]

on the actor of the object being thrown i guess now im thinking bout it it needs to be on the floor rather than the thrown object right?

[odd ember]

no the actor is fine

but you need to be sure that it has generates hit events checked

[spring bramble]

okay I had the collison box simulating on hit results but not the static mesh its self it now works on hit but it results in the same issue of only working when being held rather but if its thrown it is completely ignored

[odd ember]

can you show your setup?

[spring bramble]

can do 1 second

[odd ember]

(... and they were never heard from again)

[odd ember]

ah

can you show me the physics settings in the details panel for your mesh?

[spring bramble]

thats the physcis for the thrown object

the simulated physics gets turned on once the object is thrown but turns back off on pick up so the player can hold the object again

[odd ember]

ah sorry I meant the collision settings

[spring bramble]

no probs xD

[odd ember]

that does look alright

try enabling ccd

and do a print on the event hit collision

[spring bramble]

coolios ill try that quicklu

quickly *

[fallen glade]

is there a way to calculate a clockwise angle between two vectors?

or any angle in BP?

[spring bramble]

still ends up with the same solution on holding object it finds the floor, but when thrown it finds nothing on hitting the floor

[odd ember]

hmm that might be some physics related stuff

try in the #legacy-physics channel

though it should work

[brazen merlin]

you'd be looking to work at quaternions i believe

[odd ember]

isn't there also an even for physics volume cahnged?

[spring bramble]

also just found that if i pick up the object after it hits the floor it activates the game over 😅 so definately physics and yeah ill try in the physics channel thanks for the help though

[spring bramble]

im not to sure lemme check

yeah it does

[odd ember]

you could try and see if that triggers on throw

but I would recommend that you speak to people in the #legacy-physics channel I'm sure they would know

[spring bramble]

yeah ill look into it and ill ask over in the physics channel and see what they say thanks appreciate the help

[desert relic]

How do i create 2 cursors for 2 players

in local multiplayer

1 cursor controlled by mouse other by joystick

[odd ember]

use get viewport size

and the input values

if you add 1 then multiply by 0.5 you can get the input axis value from -1..1 to 0..1

which you can multiply

onto the viewport size

[desert relic]

i mean how do i create that cursor

so that it can be seperate from the mouse cursor

[odd ember]

a cursor is just a widget

so just spawn another widget

[snow jolt]

Is there a way to get the list of object that collide with a mesh?

Without a hit event

[odd ember]

well

you can check every frame if one object is within the other object's bounding box, or close to it

but you'll be better off with collision

[snow jolt]

Or is there a way to check if an object doesn't have any collision?

[odd ember]

the above

[snow jolt]

But how wich nodes

I tried using is overlapping but doesnt work

[odd ember]

I just told you

[odd ember]

.

[timber knoll]

overlapping should work in case you have it enabled on the mesh

[odd ember]

probably wrong collision settings

[snow jolt]

Im using the physics actor preset and am currently using the rolling ball template

[desert relic]

i can only move the cursor by a bit

from gamepad

why?

and when i stop moving it

it defaults it to center of the screen

[timber knoll]

your math is all messed up

[gentle urchin]

you're not saving its relative location

[timber knoll]

axis values are -1 to 1

ooh you want it to keep moving

[desert relic]

yes

[timber knoll]

yeah then you need to add it on top of last location

[gentle urchin]

limited to screensize x,y

[desert relic]

if i change it to 1920x1080 then when i move it a bit

it straight up teleports

to top of the screen

[gentle urchin]

top left i would think

[desert relic]

wait

[timber knoll]

why do you have these 2 tho

[desert relic]

i dont know i watched some tutorial

lol

[timber knoll]

you watched tutorials on math 😛 ?

[desert relic]

tutorials on moving cursor by gamepad

he did this shit and it somehow worked for him

can someone help me fix this lmao

how do i save its last location

[timber knoll]

store the 2 values before you draw rect

[desert relic]

i dont understand

[timber knoll]

hold on

[desert relic]

so i need to make a separate variables

for x and y

[timber knoll]

yes so you can store the last value

[odd ember]

dude I gave you the instructions to make it work

if you're using any kind of XInput compatible joystick you can use input axis with MoveRight and MoveForward

[desert relic]

how do i update the last value

can i update it by

wait

[timber knoll]

it's all in my example

[desert relic]

can i update it like that

[odd ember]

also doesn't DrawHUD run every frame on it's own?

[timber knoll]

hmmm might not be every frame, but basically

[odd ember]

anyway you can do it without even being inside of the HUD class

since you can GetViewportSize inside the player controller

[odd ember]

all inside player controller

[desert relic]

@timber knoll is this how its supposed to be

[desert relic]

bro idk how tf do i use this

[desert relic]

what after this?

[odd ember]

do you have a widget for your cursor?

[desert relic]

no

i will create one

[odd ember]

yeah do

[desert relic]

it will be this for now

what now

[odd ember]

for now, inside your player controller you can create that widget

and set it as a variable

[desert relic]

widget variable?

[odd ember]

use the CreateWidget node

[desert relic]

is this good

or should i have created variable for something else?\

[odd ember]

well you haven't created the variable, just the widget

[desert relic]

the cursor widget is a variable

[odd ember]

from the blue pin at the end of the CreateWidget node promote to variable

[desert relic]

oh that one

like this?

[odd ember]

yeah

but

actually

no

you need to connect the out pin

from the Set node

to Add to Viewport

[odd ember]

yes

[desert relic]

what next

[odd ember]

so from your widget variable

you should have something like...

set position

or set location

[desert relic]

this?

[odd ember]

yep

so for right click on the position pin and Split pin

[odd ember]

so now you can probably see how this lego brick connects with the previous lego brick construction I showed you

[desert relic]

yea i do

thanks

the only thing

i dont have MoveRight

[odd ember]

just a note: the set position needs to be set on input

[desert relic]

And MoveForward

[odd ember]

then head into your Project Settings > Input

[desert relic]

i didnt create the axis bindingsi guess

[odd ember]

yep

[desert relic]

I have gamepad right tho

can i use that

[odd ember]

I don't know which controls your controller uses

so it's trial and error for you to find out

[desert relic]

w8

u here use

move right

and i have gamepadright X and gamepad right Y

[odd ember]

yeah that's just the name

it doesn't correspond to the input, it's just the default name of the axis value

I don't know, this is #blueprint

[naive gazelle]

where do i talk

[desert relic]

So it can be Right X or Right Y

[naive gazelle]

with these problems

[odd ember]

#graphics maybe?

if it's UE5 then try one of the UE5 channels

[naive gazelle]

ty

[odd ember]

I don't know which controls correspond with your controller. you have to figure that out yourself

MoveRight and MoveForward are default names used by epic for templates

they are just names

[desert relic]

Yes

[odd ember]

nothing more

[desert relic]

i have a problem

its not showing the widget

the cursor

[odd ember]

did you hook it up on begin play?

[desert relic]

i guess i did

[odd ember]

remove the last Set Position

you need input events for that

and you need to follow the other lego brick I gave you

[desert relic]

what should move forward

be

Y?

[odd ember]

well if you look at screenspace you probably need better naming

so forward could be up

and right could be.... right

[desert relic]

ok so where do i connect this now

[odd ember]

you should have input events now

[desert relic]

u said that i have to remove set position righ

[odd ember]

from setting the input

so look for something like InputAxis

[odd ember]

yes

[desert relic]

i found this

nvm

this

[odd ember]

try it

[desert relic]

where do i plug it

this?

[odd ember]

no you need it to run set position

and set position doesn't run on begin play

and you don't need to set variables for the floats, you can use them directly

[desert relic]

where tf do i put set position

[odd ember]

think

[desert relic]

i dont know im 1 digit iq

[odd ember]

what red node did you just pull out

[desert relic]

Gamepad left thumbstick X- axis

[odd ember]

so where can you connect it then?

[desert relic]

set position?

[odd ember]

show me

[odd ember]

correct

well

almost

you don't need variables for the floats

and both events need to connect

[desert relic]

good?

[odd ember]

you need the rest of the math still

[desert relic]

good?

[odd ember]

try it

[desert relic]

nothing again

[odd ember]

probably your cursor is tiny

[desert relic]

now its not and again it didnt show up

[odd ember]

remove the canvas panel

and it can still be tiny

[desert relic]

it removes the pictrue

[odd ember]

so add a new one

[desert relic]

i did

again

nothing

[odd ember]

head over to #umg to see if you can get the cursor to spawn properly

but the logic should be correct for moving it

assuming you picked the right input axis

for your particular controller

[desert relic]

yes but the widget isnt creating

[odd ember]

#umg

[desert relic]

ohhh

i know why

shit

when i press ready i remove all widgets

[odd ember]

well there you go

[desert relic]

what the fuck

[odd ember]

means that your cursor wasn't created

for whatever reason

I can't tell you why

but #umg might

[desert relic]

here it is down there

its moving tho

[odd ember]

hmm

ok

well

no problem then

[desert relic]

but it throws 11 gazilion errors

[odd ember]

click on your cursor variable

[desert relic]

and it defaults back down there

[odd ember]

right click

and select Convert to Validated Get

then on IsValid plug it into position

leave the other path

[desert relic]

where tf is that

oops

[odd ember]

that'll be why

you can't use pins between execution paths

that's going to give you errors

you need a new variable

that's why we made it a variable in the first place

[desert relic]

what do i do

[odd ember]

on the left side

select cursor and drag it into your viewport

select Get

[desert relic]

then

[odd ember]

once you have it, right click and convert

[odd ember]

.

then hook it into your set position

[odd ember]

.

[odd ember]

.

[desert relic]

what do i do with "add to viewport"

[odd ember]

you f'd up

why do you bring it back into set position from there

nobody said that

[desert relic]

whaat u said that i should hook it up to set position

[odd ember]

yes but not from beginplay

[desert relic]

so this?

[odd ember]

also you completely f'd it

yes

no

why do you have a validated set

is said Get

come on

you gotta listen

[desert relic]

i did get

and it is get

[odd ember]

ok

so where is the set node now

why is gone

[desert relic]

here

[odd ember]

.

[odd ember]

the get needs to be with the other execution path

[desert relic]

i switch up get and set?

[odd ember]

no

read pls

[desert relic]

with what execution path

[odd ember]

where get position is

[desert relic]

this???

[odd ember]

no

...

christ

[desert relic]

bruuuh

[odd ember]

yeah bruh you

[desert relic]

bro idk where to fucking hook it up

[odd ember]

hook the red nodes into the get, into the set position

christ

[desert relic]

is it finally good no

w

[odd ember]

yes

just hook up the set to add to viewport

and connect the pin from the get to the set position

[odd ember]

try it

[desert relic]

its working

buut

its defaulting

offscreen

and its not going frame by frame

[odd ember]

it is as long as you hold down the input

unless your controller is broken or something

[desert relic]

yes but when i stop moving

[odd ember]

from GetViewportSize, multiply both of those with 0.5

[desert relic]

why?

[odd ember]

do you want to fix your problem?

all this time you've been fine following what I said now you're asking about why we're doing things

lmao

[desert relic]

i did it

but im asking why

[odd ember]

to center the viewport

so your cursor starts in the middle

[desert relic]

doesnt look center to me

[odd ember]

show me what you did

[odd ember]

.... you didn't multiply by 0.5

lol

[desert relic]

wdym i did

[odd ember]

no that's just the previous logic that I showed

you didn't add the extra change that I asked you to do

[desert relic]

noow?

[odd ember]

do it before the other logic

[desert relic]

oh okay

[odd ember]

or actually

let's just do something real quick

create a new set position node

[desert relic]

then

i mean this aint too bad

its suposed to be on that side anyway

the only problem is

its teleporting

not going frame by frame

[odd ember]

do this after you set the cursor variable on begin play

as for why it's not going frame by frame, it should follow the framerate

so either your controller is busted somehow or your framerate is low or your widget has some weird settings

[desert relic]

if i straight up go right it teleports to right

but it goes slower

i think sensitivity to high

[odd ember]

yeah

so you can add a float variable

called Sensitivity

and multiply it onto where you have the other logic

you need to do this for both x and y

[desert relic]

can i do it in project settings

[odd ember]

yes but also no

you can set the value of the axis to be lower

at the risk of screwing all the logic

so I'd recommend you do this as a separate value

[desert relic]

and how do i set sensitivity then

[odd ember]

just set the default value really low to start

like 0.01

and adjust as needed

later on you can set that to be a custom setting somewhere

[desert relic]

this?

[odd ember]

but that's another can of worms that I'm not gonna open with you

where you have the 2nd 0.5, hook it up into there

on both x and y

[desert relic]

so i should create sensitivity and hook it into 2nd 0.5

[odd ember]

on both x and y

[desert relic]

it just lowers space where it can move

[odd ember]

ok but is it at least slower now?

[desert relic]

no

it teleports

only not that far

[odd ember]

try setting it even lower and see if it keeps teleporting

[desert relic]

i realised whats going on

its not repeating

like if i hold right

i teleports and thats it

[odd ember]

on the set position node

try unticking the DPI checkbox

but tbh I think it's your controller that has binary input or something

because that corresponds with why you're not seeing a steady increase or decrease

so you need to setup your input properly for this

[gentle urchin]

Isnt this an issue of not keeping track of current position? Atleast it looked like it was

[odd ember]

nah we're scaling the mouse position to viewport

[gentle urchin]

So its supposed to reset to center?

[odd ember]

but given it's teleporting it sounds like there is no inbetween from 0 to 0.5 to 1

which is true for boolean inputs

[gentle urchin]

Or low res analog sticks

[odd ember]

yes

[desert relic]

Dude its not my controller

[gusty shuttle]

Is there a reason why I don't have the option to create a new skeleton (right)? The normal one is on the left (every tutorial out there) and for some reason I just don't have that option when bringing in a mixamo skeleton

[desert relic]

In the real planrs vs zombies it aint teleporting

And i have 60fps

[odd ember]

well you didn't set up the input events properly

so it might be that your controller is ok

but I don't know which values it uses

because you shortcut it

[atomic salmon]

On the right you are importing an animation to associate to an existing skeleton

[odd ember]

not sure why this is in the channel anyway? seems like #animation

[atomic salmon]

More #ue4-general as this is a generic question on using the engine

[gusty shuttle]

Aye, fair enough, thanks for answering

[heady saffron]

Can someone tell me why my character doesn't go up the ladder on this blueprint? he just stops movement completely.

[odd ember]

does it work if you stop input and retry?

[heady saffron]

@odd ember no

[south bone]

I want to be able to call "ce <customevent>" using my gamemode instead of having it be tied to level blueprints. Is it possible to add a custom event to the level blueprint from the game mode blueprint at runtime?

[odd ember]

sure

you can use GetGameMode

[heady saffron]

Ce u got any ideas?

[odd ember]

nope

[heady saffron]

been playing around with stuff and idk why it isn't working

hmm alright

[odd ember]

debug it with breakpoints

is my best advice

see if the bool is true

[heady saffron]

will try that, not much else to debug tho

[odd ember]

the place where you set the bool, the value of the axis, the up axis being correct

etc.

you can try ticking force as well

it might be that the CMC ignores up input by default

[south bone]

I wasn't clear. I am trying not to write code in the level blueprint cause I want the commands to work at any time the gamemode is active instead of being tied to levels. 'GetGameMode' would only be useful if I am writing it in the level blueprint right?

[odd ember]

the event(s) would still exist on the game mode

you're just calling them from the level blueprint

doesn't mean you can't later call them from somewhere else

or even use the command yourself

[heady saffron]

Damn nothing worked... Will keep playing around with stuff like if flying is enabled etc... must be something small like that holding it back

[odd ember]

probably is yeah

check the flying movement section under the CMC

to see if there's something there

[heady saffron]

at first it was disabled, but enabling it didn't fix it

[south bone]

Ok so I made a new level, "LEVEL_BASE" for all of my existing levels to inherit from, so they can all have the same set of commands. But it doesn't show up if I try to reparent the level blueprint of an existing level. Am I missing something here?

[odd ember]

a level script actor is not the same as a level

and to be honest I'm not sure you can create a level script actor in blueprint

[south bone]

Ok so I'm starting to think it is just impossible to make all my levels share a set of commands without copy/pasting all of the events each time.

[hardy fable]

Create a Level Script Actor class, and in project settings change the Level Script to your custom one, like this:

whats fun is that level script actor classes dont show up when making a new blueprint

you have to click the + icon next to the selection in project settings, unless im just bugged

[south bone]

I already closed my project to go grab lunch but thanks @hardy fable . I'll try that out when I get back.

[vocal pumice]

How can I use blueprints to make an ability target the mouse location?

Don't need a targeting reticule or anything like that, just press ability and it goes to mouse location instantly

[wooden adder]

Instead of having the new target view as third person character I want to set it to a camera from a different Blueprint, how do I reference that camera

anyone any ideas?

[south bone]

That worked (almost). All my levels show the command. However, for some reason calling the command doesn't do anything.

[trim matrix]

rookie question

i'm bad at maths I need 75% of a number in this case 75% of 104 but want the game to work it out

incase any levels made have different overall number of pellets

i've tried 75 / 104 * 100

sorry 104 / 75 = XX * 100 = XX

for some reason this isn't working ??

where my maths failing please

hang on there a percent node on UE4

75% of 104 would be 29 that correct thats waht U seems to thing anyway

[supple dome]

104 * 0,75 = 78

[faint badge]

To expand on this, to find any percentage first divide your number by 100 to get 1% and then multiply by however may percent you need, in this case 75. Due to how multiplication and division works you can just calculate 75 / 100 first and then multiply your number by it. i.e. (SomeNumber / 100) * 75 is the same as SomeNumber * (75/100) or SomeNumber * 0.75.

Because dividing by 100 is just moving the number two decimal places to the right you can easily figure out what value you need to multiply by. For example if you want 25% it will just be 0.25. For 125% it will be 1.25 and so on

yeah for some reason taking the 104 vaule down to 0.75 or atleast the way i was doing it it wasn't liking

Does anyone knows about the Replay System with the Console Command in BP the question is the Camera spawn i think in the middle of the Map ,how i can set the Camera or Move it to a specific location or can i controll the Movement anyway of the Camera

[dark crow]

You can create a math library too to have common stuff like that right there when you need it if you keep forgetting how to do it

[odd ember]

those nodes are so dark they're almost invisible

Not really sure where this fits in but:
I'm currently trying to achieve offsetting a Relative Transform location.
I have an Array of Actors
This I put in a ForEach loop and spawn a Spline mesh component.
my question is how can I offset them in Y Coordinate based on the Array's length?
For example
Distance float= 50
Array Length = 5
Result should be:
-25
-12.5
0
12.5
25

Any guesses? I would search the internet but can't really find a term for it

1 Entry = 0
2 Entries = -25, 25

so it spans out equally

[odd ember]

I think I would need to see a visual of this to understand it

[static charm]

you can use a Mod of 2 and when result = 1

and set the 12.5 to negtive

and multi that by the index of the loop

Hi all, anyone know if its possible to add a socket to a skeletal mesh in blueprint, in the construction script for that blueprint?

I see a "Add Socket" node, but I'm not sure what's supposed to go in the bottom pin for the Socket Asset... I cant seem to create a "Socket" asset..

[odd ember]

afaik a socket is just a transform

[fair magnet]

uhh... Don't think I understand that :o
So I take my Distance of 50 mod them by 2 ?

[static charm]

yeah nevermind i didn't think it though lol. i dunno

[faint badge]

The function is normally called linspace however unreal doesn't have an implementation. It's easy to right though

First you set the value to be -(YourFloat / 2.0) and then you set your Stepsize to be YourFloat / (Length - 1) . Now in your loop you use the value, then add on your step size to get the next value

[keen wedge]

Any thoughts as to what goes in that bottom pin though?

[odd ember]

you can hover over the pin to find the class

[fair magnet]

Can I calculate the stepsize ? or will I have to just set that manually ? :o

[keen wedge]

Yeah, it says "Static Mesh Socket Object Reference"

but I can't create one of those as an "asset" despite it having a search... I think its for hooking it up to a socket you've already created manually on a static mesh

[fair magnet]

oh wait nvmd that's what you said already lmao

sorry

so far that's what I got

[faint badge]

You can calculate it, it's just Distance / (Length - 1) using the names from your example. So if Distance = 50 and Length = 5 the Step size is just 50 / (5 - 1) which is 50 / 4 or 12.5 like we'd expect

for Distance = 50 and Length = 2 we get 50 / (2 - 1) = 50

Just be careful as you have to check the case that Length = 1 as you'd get Distance / (1 - 1) which means you divide by 0 and it'll throw an error. You need to decide what should happen in that case (maybe just return 0?)

[odd ember]

possibly? I don't know that sockets can be added in BP. as far as I've seen they're only used in mesh editors

the closest BP equivalent is a scene component that you could perhaps offset from an existing socket

[keen wedge]

The reason I wanted to "create" one, was so that I can avoid passing all these string references around for the socket names (does my head in!)...

I figured if I created the socket in the construction script, I could then store its name "once" in a variable on the object... then, when used, just access the variable...

but if I can't do that... Im back to crappy string references 😦

[odd ember]

why are you referencing socket names constantly?

[fair magnet]

Thanks alot! That helps :D

[keen wedge]

You put the name in the socket itself - so thats one...

Later, using a Physics Handle, I need to set the "In Socket Name" - so that's twice

and I think, in Tick, I'm going to need to constantly set where this thing is (as its sway about a bit outside of the animations at the moment) - which means I'll need to use the string reference again for that too!

[faint badge]

Those should be two separate things and saved to variables. Make a variable called something like CurrentOffset and give it the value -(Distance / 2 ), then make another variable StepSize and set it's value to be Distance / (Length - 1) then in your loop you will do something with CurrentOffset and then afterwards you set CurrentOffset to be CurrentOffset + StepSize. That way for Distance = 50, Length = 5 you would have -25 first, then -12.5 on the next loop, then 0 and so on until you hit 25 at the end

[odd ember]

you may have better luck asking in #legacy-physics

[keen wedge]

okey dokey... thanks anyway 🙂

[fair magnet]

Did everything like you said but it's still not centered :(

Note that the "Output Vector" Variable just has a Fixed X of 50... is just so the lines do not start inside the button

[faint badge]

Swap the order of your Add Spline Mesh Component and your Set Offset node. You need to use it first and then update it. You're updating before you used it

[fair magnet]

uh? What exactly do you mean by set offset node?

[fair magnet]

oh

true

yea! now it's fixed :D Thanks alot really!

[faint badge]

What's happening is you're adding the stepsize to the offset before you use it. So using the Distance = 50, Length = 5 example you set the Offset to -25 and then before you use it you add 12.5 and have -12.5 so rather than -25, -12.5, 0, 12.5, 25 you get -12.5, 0, 12.5, 25, 37.5

[fair magnet]

yea sorry kind of forgot about that

[faint badge]

No worries, glad you got it sorted!

[fair magnet]

Now I need to go for the complicated part... wish me luck lol

[faint badge]

Good luck!

i feel like more people use blueprints rather than cpp

[odd ember]

almost as if the barrier to entry is much lower with blueprints

There's not much inherently wrong with that.

[icy dragon]

Tick overhead, trap of some questionable practices? Fuck yeah, even though it's not entirely BPs fault.

Also your baby might speak C++ since birth, but not everyone is. BP is good for protoing gameplay quicker than writing it in C++ out of thin air. At least that could help designers and engineers to be on the same page.

[trim matrix]

people who dont want to code

[trim matrix]

true

[odd ember]

people who can't code

[icy dragon]

Well, it's cool if you speak int main() as a baby, so does your elders.

I give you that if that's actually happened

Though realistically your elders should speak assembler (or even Fortnite Fortran), but that's nitpicking.

[static charm]

you're doing it wrong if your not manually setting your bits with a magnet/voltage switch - directly to storage.

[trim matrix]

haha

Screw it, transistor is shit, absolute heresy. Real man use vacuum tubes.

I'm sure vacuum tube users get VIP access to hookers and blackjacks.

Transistor peasants can go screw themselves.

The point is, C++ and Blueprints have their own strength and drawbacks, and they can be used together.

It's not about superiority complex about one or the other.

anyone know how to use this plugin?https://github.com/BenPyton/ProceduralDungeon

[icy dragon]

The same crap can be said for any scripting languages or any level programming languages, if "the hardest to do always superior" is the measure.

[icy dragon]

Nope. Least not me.

[icy dragon]

Though it's a good rule of thumb to always read the manual.

[dry jolt]

and i did, and still not really working for me.

at least have the setup

or just leave it and do some design first sound good

not really relevant to this channel, or perhaps even this discord. you should contact the owner of the plugin. but you may find some assistance in #plugin-dev

Hey guys, is there a way to filter data tables based ona boolean in the data table?

[odd ember]

as in data table queries?

I don't think so

but you can filter them once you've loaded the data

yeah
