blueprint

[somber elbow]

and i m not quite sure where i should plug in this massive

[somber elbow]

now its is constantly blinking

[hollow cove]

mhm are you getting hit multiple times

[somber elbow]

no

i use on launched

[hollow cove]

ive never used the launched event, i assume its only possible to trigger it while youre on the ground or?

[somber elbow]

i checked it with print string

it shows one messege on overlapping so its fine

[hollow cove]

oh youve got the false instead of true...

[somber elbow]

something is just wrong with the logic

nah

i tried different

[hollow cove]

are you sure current velocity is correct?

we usually use this node on characters

then youd just split and get the z value

[somber elbow]

yes

i just made a variable

behind it its exactly that node

@hollow cove

[hollow cove]

very strange. try adding this before reversing perhaps? struggling to figure out why itd be doing that assuming that launched is only triggered once

oh i see

you notice it worked on the first couple jumps but when it didnt have enough time between jumps it did that

[somber elbow]

idk its just constantly blinking

[hollow cove]

yeah so you need to sort of cancel the current blink and reopen the eyes as it hits a new launch

hmm

[somber elbow]

why i cant just check every frame if its jumping or not then check if the timeline is playing and if not play the timeline

i tried to do it in event tick

but thats not right as i understood

its just so complicated and i have never used these nodes before

for such a simple thing

[hollow cove]

oh wait i thought of a way simpler way

so make the float track look like this

[somber elbow]

im trying

[hollow cove]

could be this for simplicities sake

it does mean that itll cut to the start where the eyes are fully open whenever you hit a new bouncing thing though

should look natural in the context?

[hollow cove]

right click add new key

then select the dot and top left is the time and value

[warm olive]

Hi, I created a blueprint that makes a chain. Everything is done in the construction script, including adding and configuring the physics constraints. It's almost entirely working, but it seems that no matter what I try, the chain stretches and jumps around.

I want the chain to swing and move when interacted with, but I don't want any stretch in the physics constraints. Any ideas I what I could do to fix this?

[somber elbow]

@hollow cove

[hollow cove]

play from start

if you play its playing then when its at the end youre telling it to play but its already finished

[abstract pebble]

the print string is for inputs of the do not = and the output of the do not =. it works properly for every single input until 33.333 and then when both are 33.333 it still is outputting that they do not equal the same. could someone explain why this might be happening?

[somber elbow]

yep, it works! Thank you Olie.
The sad thing is that i still dont understand the global approach. Now i should implement the biting and i will have to deal with the time line again. Its just another morph target there.

[hollow cove]

try using nearly equal, this is probably just floats being dumb

[hollow cove]

are timelines confusing you or? It's just basically event tick for x amount of seconds that you set. it also outputs the float value at that time. so if your timeline is 2 seconds and the float is a linear line from 0 to 1 at 1 second the float value will be 0.5.

[somber elbow]

yeah

[hollow cove]

okay i should stop procrastinating, good luck

[abstract pebble]

that worked! i didn't know that node existed, thanks :D

[hollow cove]

👍

[somber elbow]

Thank you so much dude

[lunar sleet]

Floats being dumb
AKA floating point error? 😀

[eager thicket]

How do I remove two of the decimals points on a number like 0.142? So it prints 0.1 instead?

[flat coral]

1. Why does autocomplete "helpfully" show Equals as an option for this pin type when it's not a valid connection?
2. Before I write a dumb hack I shouldn't have to write, is there a "right way" to compare data table row handles?

Like this is just straight-up lying. That action does not take that type.

[maiden wadi]

ToText parameters

[maiden wadi]

1. UE5's math nodes suck.
2. Not in BP. Just make a bp lib that breaks them and == the datatable and rowname.

[lunar sleet]

you mean ToString , == String is not proper design? 🙃

can you even convert an item row to string? prly not? 😅

[maiden wadi]

String?

[flat coral]

I've since realized I'm dumb, my item data tables are static per-level for unrelated reasons so I just need to compare name anyways.

[lunar sleet]

you made me question whether I typed the word correctly for a second there lol

[flat coral]

With the power of JSON you can convert damn near anything to a string

Now, whether you SHOULD, that's a different question 😛

[lunar sleet]

https://tenor.com/view/jason-bourne-identity-gif-24953824

[maiden wadi]

But where do strings come in?

[flat coral]

Behold!

[lunar sleet]

idk, I thought maybe you can convert the actual row to string format, but haven't really dabbled with DTs that much to see if that's even valid. was half joking

[flat coral]

The row itself is just a Name so that's easy. But the problem is the Data Table reference, which is just an object reference.

[lunar sleet]

ah

[flat coral]

Which CAN convert to string, but that's one of those things which is simple to do, and also easy to fuck yourself with if you don't understand what that actually means.

[maiden wadi]

But why not just == the datatable pointers?

[pearl compass]

something that could work.

[flat coral]

In theory I could, but there was some pretty complicated searching code I was writing for something else and I realized if I accepted the limitation of one item data table per level, it would get 10x easier to write

and i didn't REALLY have a good reason to preserve the ability to have multiple item data tables per-level. I don't have that many types of items anyways.

[maiden wadi]

Data Assets. 😄

[abstract pebble]

what yall think about my bp?

[abstract pebble]

idk if this is normal size for a bp

im new to game dev

[abstract pebble]

XD

[flat coral]

Part of me thinks you did this on purpose. Took a BP that was already a little fucked and just moved a few nodes to make this rats nest for the meme

[abstract pebble]

no

its really my bp

it works too

[flat coral]

Like this stuff in the corner proves you know where the Q key is at least

I mean, it doesn't ALL work. Some of these nodes are for sure connected to nothing.

[abstract pebble]

true

it is a lil messy

[lunar sleet]

the majority of the time you will spend programming is reading code not writing it

[abstract pebble]

few times i set up stuff to try and fix issues but then give up temporarly and leave the nodes there

[maiden wadi]

You seem really stuck on this topic.
#blueprint message

[lunar sleet]

so if you make it illegible you're going to have a hard time

[abstract pebble]

idk what i was making was so complicated i couldn't even find a way to make it have a clean readable stucture so i just gave up and let it be a mess

a bit of a excuse tho, i didn't try very hard to organize it

[lunar sleet]

I find it a lot easier to organize as I write rather than try to reorg later

[warm olive]

If this isn't the correct forum for my question, can someone point me the right direction? I've been trying to solve this problem for days, read all the articles I can find, official docs, watched every video on physics constraints on youtube...Nothing seems to help, and it only seems to happen when the chain is made with a BP, I can reproduce the same chaing manually in the viewport and it works fine...

[flat coral]

I actually kinda do the opposite.

[lunar sleet]

provided it works for you and the end result is not that screenshot they posted, 🤷

[flat coral]

Though the exception is like... "assuming a function"? I forget the actual CS term for it. Where you stub a helper function to just move on from that with the larger function, and then implement it later.

[lunar sleet]

yeah ik what you mean, tho I don't really do that

[flat coral]

Physics constraints are tricky tbh

When you add them via viewport they start with a lot of sane defaults that you don't get when you create them in code

[flat coral]

I dunno if this'll be helpful for you, but here's the code I'm using to attach a newly-created physics constraint to an actor (the end result here is like a sticky spider web which "grabs" an actor when it collides)

The reference position shit in particular is a real "gotcha"

[sinful topaz]

Can someone please help me with something? I want to transfer a vector variable from one BP to another and I am very new to this stuff. I tried it with casting but it doesnt work, it doesnt transfer the vector data. Is there an another way to do this?

[maiden wadi]

To help you, it would require an understanding of what these two actors have in common and the requirements for the transfer. EG getting an actor globally can work, but it's not so great if you just want something to happen when two things are nearby. In general I would recommend sitting through this. https://www.youtube.com/watch?v=EM_HYqQdToE

[warm olive]

@flat coral I thought that the Constraint Reference Position and Constraint Reference Orientation were set by the Add Physics Constraint Component. Is that incorrect? The Unreal docs don't seem to cover this very well. I'm creating the mesh component, the physics constraint, then setting the constrained components, based on the gizmos, the position and orientation appear to be correct. And you are setting in two frames, which I'm not, but also isn't when configured manually, or am I missing something?

[flat coral]

I mean, they're set auatomatically, but from what I found they were not set to sane values.

Let's back up, what's the problem you're running into?

I beat my head against these things for a LONG time to get the results I wanted. You're right about one thing for sure, the docs suck

[warm olive]

@flat coral The constraints stretch. The links start out in the correct location, but when gravity kicks in a runtime, the they settle correctly and then the links appear to stretch apart elastically, then snap back, causing the chain to jump.

[dawn gazelle]

ToText (float) has settings on it that allow you to specify how many decimal places you want.

[warm olive]

The constraints look like this when they're spawned, which looks like what I expect, relative to the meshes:

[outer quail]

Why does this keeps crashing my ue5? When initially run there is no problem, but once the value updated triggered, it will crash ue5. This is widget blueprint

[maiden wadi]

What does SetRenderTransformAngle call?

[outer quail]

the pointer

[maiden wadi]

Oh, on UWidget, yeah.

[flat coral]

Wait, is setting Pointer Angle triggering Value Updated in an infinite loop?

[maiden wadi]

Unlikely to cause a full editor crash.

[outer quail]

It supposed to update only when the bind event to value updated is triggered, maybe I did it wrong

because without the bind event to value updated, its not updating the angle when the rpm value is updated

[flat coral]

(I'm actually with Authaer on this one, I've gotten actually useful error messages any time I made a loop like that before. It's just the only theory I can think of)

[pastel garnet]

are you sure the actor is valid when you bind to it?

[lunar sleet]

should be getting an accessed None usually but an isValid check wouldn't hurt there

[flat coral]

What if you just don't set the pointer angle variable at all? If you separate the SetRenderTransformAngle node into two cases, you can just pipe the pointer angle right in without storing it first

[thin panther]

you do appear to be dragging wires across events though, especially function return values, which is a no-no

[maiden wadi]

Do you get any sort of crash log?

[outer quail]

no crash pop up

its calling the value

[final berry]

Am I correct to say that dividing an uneven int using this node always results in a floored int? i.e. 7 is always 3 and 11 is always 5?

[warm olive]

@flat coral

[quaint fable]

Hey there. I'm trying to get this stamina system to work. When I sprint, the bar goes down, but when the bar is empty I am still able to sprint. Can anyone show me what I'm missing here? Please hold for screenshots

[thin panther]

yes.

[warm olive]

OK, I lied. I tried this chain and anchor made manually and found that if you're actually paying any attention, the link is clearly jumping around on the anchor (the anchor has no physics sim enabled). The only reason it's not as obvious is because there's only a few links. The more complex the chain, the more noticeable this becomes. But it's always an issue, apparently. So, I've been trying everything I can think of, but the jump/jitter seems to be a constant.

[final berry]

Do you also know why? Why not Round, why Floor? 🤔 I mean 7/2=3,5 is usually 4, no?

[thin panther]

because it's an integer, you don't round it.
If you're asking how many times 2 goes into 7 wholly, it's 3

An integer has no concept of a decimal place.

[thin panther]

If you wanted to split 163 grams of flour into 40 gram portions, you couldn't invent an extra 37 grams, you'd have 4 portions and 3 grams to go back into the bag.

[final berry]

Crystal, thanks 🙂

[thin panther]

np!

[slender dagger]

try plugging the ongoing into the first branch where you check the stamina

[quaint fable]

I'm not exactly sure what you're referring to

[steel star]

im having issues with SpawnActor node not seeming to know when it is overlapped. the thing being spawned, and the thing spawning it both have static mesh collision components, and i also gave them collision shapes too, but maybe my settings for those are wrong? what is it that counts as blocking, when spawning?

[quaint fable]

ohh lol yeah, thank you. let me see what happens

[quaint fable]

Nothing happens

[slender dagger]

wdym? Like the sprint doesn't start?

[quaint fable]

the sprint starts, but when I'm supposed to run out of stamina, the player continues sprinting

[slender dagger]

I'll have another look at it, but see what happens if you change the triggered to started and keep the ongoing in

[quaint fable]

Nothing

[slender dagger]

try having a look at the execution flow while it's running, I think you might not need that first branch as well btw, but that shouldn't be what's causing it

you could also breakpoint it when the sprint stops

oh wait I know what it is

It's because when you set your stamina to 0.0 it still returns it as true

[quaint fable]

so i would want it to read when the percentage of the stamina is at zero, yeah?

[slender dagger]

change the check to less than or equal to 0.0 and change the true and false around

[slender dagger]

no it's just you've used the wrong operator to check the value

because it's clamped to 0.0 it doesn't go any lower, and when you check the stamina value it still returns 0.0 as true because it isn't less than 0.0, it's equal

[quaint fable]

It still does the same thing

[slender dagger]

show me what you've got

just what was in your first screenshot

[slender dagger]

have you tried waiting for a couple more seconds? I think your delays might be causing it

if it's 0.1 it will still go down the sprint path after it takes it off

also it might be worth printing the stamina

[quaint fable]

I'm not sure I follow

I changed the delay times to 0.1. That just makes the stamina bar deplete faster

How can I print the current amount of stamina?

[slender dagger]

just do event tick print string and then plug the stamina into the text

Then again if it's a stamina bar you shouldn't need that

have you tried breakpointing it to see if it actually gets called?

[quaint fable]

when I print the stamina, it shows the value correctly, all the way down to zero

what would I breakpoint?

my apologies, I'm still learning

[slender dagger]

the setting max walk speed to 100

[slender dagger]

it's alright. No one fully knows Unreal lol

[quaint fable]

yeah lol it's confusing. would it be break point int?

[slender dagger]

no like hover over the node and press f9

then play it and keep sprinting and tell me if it ever goes back to it

I can hop in VC if that would be easier

[quaint fable]

oh im on a mac

[slender dagger]

right click on it and press toggle breakpoint

[quaint fable]

I added a breakpoint

I got a giant red arrow

as soon as I ran out of stamina

[slender dagger]

so it is being called then

hmmm

[quaint fable]

yeah, it also happens any time I stop sprinting

[slender dagger]

yeah it will do that

breakpoints basically stop the game when a certain node is called

so you can see if it's actually being called or not

can you hop into vc and stream it?

[quaint fable]

no but I can send a screen recording

[slender dagger]

it's alright, I was just asking because it might speed things up a bit. What's the last node it goes to on the execution chain when you press this when the breakpoint is called?

[quaint fable]

I'm not sure if I can press that since I have to click on the viewport in order to control the PC

[slender dagger]

no i mean when the breakpoint is called it will go back to the graph when it's paused and you can follow the exec chain

[quaint fable]

It goes to this one first

[slender dagger]

yeah it will do, what's the last one it goes to?

[quaint fable]

looks like it goes to this one last

[slender dagger]

oh yeah you might have to just temporarily move them to the side

[quaint fable]

the delays?

[slender dagger]

yeah, what this is showing is what happens each tick so obviously the delay will be the last one in that tick

you can put them back in after

[quaint fable]

When I break the node links on the delays, it goes in a continuous cycle

[slender dagger]

just keep doing it

you'd get an error if it was an infinite loop

it's just changing the stamina values at that part

I'm checking to see if at any point it heads back up to the "sprint" branch

[quaint fable]

so far it hasnt. could it have something to do with this?

[slender dagger]

I doubt it, your HUD shouldn't be interfering with this from the looks of it

does it go any further

[quaint fable]

no, it just keep cycling

[slender dagger]

yeah it's updating the stamina values. What's the max stamina value?

[quaint fable]

1

same as the stamina value

[slender dagger]

just keep letting it go until it stops and doesn't let you move forward, like how it did when you had the delays in

[steel star]

Has anyone successfully used the 'overlap handling' options for SpawnActor node?
What are the collision settings needed for this to work? Because right now my actors dont seem to be responding to collision shape components.

[quaint fable]

It just keeps going

[slender dagger]

what's the value of the stamina now?

because your stamina refills every 0.001 so it might take a few loops

[quaint fable]

I set the subtract to 1, and the add to 0

@slender dagger I set this up by following a tutorial. Would it help if I sent you the video? It's a 7 minute video

[slender dagger]

I mean yeah sure

[quaint fable]

https://youtu.be/DkrQNrE_XEk?si=qSUa1AwavVptEdQD

It seems like other people had the same issue

I might be better off just trying a different way altogether?

[slender dagger]

the only difference I can see is that he isn't using EIA

but it should work with that regardless

just try unhooking the first branch that checks to see if you're not sprinting and then plug the triggered into the second branch

I don't think this will solve it but I want to see if anything actually changes

also you might want to remove the breakpoint before you play

or just disable it

[quaint fable]

What do you mean by plug the triggered into the second branch?

Oh, sorry yeah I know what you mean

It gives me an infinite loop

[slender dagger]

oooooh interesting

[quaint fable]

Oh and the value of the stamina goes straight from 1 to 0

[slender dagger]

but it doesn't when the is sprinting branch is there?

[quaint fable]

Nope

But it does keep the value of the stamina at 1 until I plug the delays back in

[slender dagger]

what happens if you unplug the ongoing and try both with and without it?

[quaint fable]

@slender dagger I have to go for now so I'll try that when I get back. Can I DM you?

[slender dagger]

Yeah sure

[quaint fable]

Thank you!

[slender dagger]

I’m gonna set this up in a blank project and really mess around with it to see if I can get a closer look

[quaint fable]

Definitely! Let me know if it's successful for you. I followed the tutorial step by step

[rose crest]

I can show how it works for me, its replicated so can be simplified, but principals are the same

[valid solstice]

anyone know why i dont have this node?

[slender dagger]

did you follow a tutorial

also what class are you in?

[valid solstice]

event graph and yeah i did follow a tutorial

[slender dagger]

no I mean class, like character, pawn, actor, widget etc etc.

but I don't have it either so it's probably something that's set up in the tutorial

[valid solstice]

Ah okay

[lethal ocean]

Is there a way to keep my player character bp from being deleted when it falls through the map?

[steel star]

that behavior is a setting on the actor, and also on world settings

[lethal ocean]

Sweet, thanks!

[steel star]

its greyed out for me because i have worlds bound checking also disabled which is ...

[lethal ocean]

Can I change the action associated with the world bounds check? Like change it from kill to something different?

[steel star]

no idea, though google found a tutorial on customizing it

[lethal ocean]

Ok, I'll take a look

[steel star]

i take that back, it was just a search result title that sounded like it, but was only a forum post

probably if you set a special damage type, you could then handle when it occurs

[lethal ocean]

That seems to be the way to go, I'll see if I can get that to work. Thanks again!

[bleak furnace]

Howdy folks, I'm trying to access a gameinstance subsystem in an Editor utility widget on pie start - but my subsystem keeps coming back as null. When I use this same logic in an actor BP in the level it works correctly - is there some trick to getting a gameinstance subsystem in a utility widget? I tried delaying the call incase the logic seemed to be loading before the subsystem, but that didn't work either.

[silver garden]

Can you change a GameMode dynamically on runtime?
Based on some data stored in the GameInstance, I want to, on Level load, change the GameMode to that particular level.
Say for example, you have options in the main menu, "Last one standing" and "Deathmatch". I would like to change the assigned GameMode based on the player's choice.

Edit: Or do I have to create duplicates of the level and each one have its own GameMode?

[lunar sleet]

No, it’s tied to the level afaik

But what it sounds like is you just didn’t set that particular level to the correct game mode to begin with

But if it’s the same map maybe you can somehow do it through cpp?

Not bp anyways

[silver garden]

Apparently you can do something like this, but uff...

[steel star]

neat

[silver garden]

Okay, yeah, that is definetly the way to do it. It is sketchy, but with some good organization and proper setup/architecture, it could work neatly.

Awesome

[merry chasm]

@steel star What sunlight intensity would you use?

The range is large, from 10 to 120K.

[steel star]

id say default, if not already. then see if adjusting it even accomplishes what you want.

[merry chasm]

default is 10

ok, thanks

[dusky cobalt]

What could I use to create effect of a circular progress ''animation''. Material, Animation with timeline? I would want to call to this thing with event dispatcher and update it's progress. Could I put it on a decal? Or maybe Niagara? If anyone has any tutorial that could give me any ideas I would appreciate.

[steel star]

https://youtu.be/BgOAbAdi8f0?si=UNi9mF8gLPSufsw8
Says its 5.0 but its from 2 years ago so its probably lying. Probably doesn't matter though

[dusky cobalt]

Looks good, do you think I could use it on a decal? I want it to be on the ground in world. I will check it out but maybe you already see that it's reusable in more places than widget?

[steel star]

so just based on scrubbing through the video, i see that he has a material for it

[dusky cobalt]

Ohh, I think I see and it should work, I will just create material instance on the actor and then call to update the progress, lovely!!

[steel star]

it does look like its not actually textured though, so its like hard edge circles

anyway this has an actual tutorial so do that, if it works

[dusky cobalt]

you typed good keywords because I didn't know what to look for, looks like there is a lot of tutorials but I couldnt find them xD thank you a lot!

[steel star]

my search was "unreal engine progress spinner"

[dusky cobalt]

https://www.youtube.com/watch?v=Xtk3v3-fFcI&ab_channel=YourSandbox I think this one gonna be fire, it usess texture.

[steel star]

By the way--how i would personally approach creating a material with some sort of circular animation--is by having a texture with a swirl in its alpha (a radial gradiant) then in the material animate the alpha cutoff, with a fade-in at the edge.

But i see there are some material nodes related to procedurally generating arcs/circles that the first tutorial was using. But that sounds more complex and less useful to me, unless it needs to scale to very large and very small sizes.

[bleak furnace]

figured this out incase anyone is curious, I needed to grab an editor world reference, do a time delay, and then get a game world reference

[dusky cobalt]

Yeah would be best if it actually scaled because every actor can have a bit different radius. Also i'm so bad at materials I think I don't understand what you said in previous message 😄 Ill give it a second thought about doing at least 1 tutorial 😄

[hoary junco]

so going off the default point and click game mode, something I noticed is if you click somewhere that you can't go like off the map, instead it just makes you go where you already are, is there a way to redo that where it will try to find the closest movable location to the place you clicked?

[steady thicket]

I have an AIController that has a blueprint graph. This AIController is attached to my character blueprint named 'BP_Enemy_Base,' which is a character. How can I get the character reference of BP_Enemy_Base in the blueprint?

[dusky cobalt]

If you use On Posseses instead of begin play you get reference to the pawn that owns it and you can cast from there to bp enemy base.

[dusky cobalt]

Also make sure to change the class of aicontroller in the bp-enemy class defaults.

[maiden wadi]

You've already done that here?

[steady thicket]

I just followed this advice, thank you

But, I'm having problem now with my enemies, since they're detecting each other and attacking them. It should only detect the character and not their own

is there like class to ignore for the Sphere trace for objects node?

[lunar sleet]

#gameplay-ai is better for these questions. You’re better off using AI Perception. There’s a pinned video in that channel that talks about Behaviour Trees but it includes a section on AI perception

[frank locust]

is there a way to do something at the end of this macros loop similar to executing something on completed for a for loop?

[lunar sleet]

There’s a bAutoRegisterAllPawnsAsSources that needs to be set to false ^

[frank locust]

Wait, neo from the unreal forums?

[lunar sleet]

Unlikely

I think I only have like 2 posts there

[frank locust]

lol yea nevermind, its a 'community hero' and i mistook his name anyway

[lunar sleet]

Yeah, I’m no hero

[frank locust]

Its Everynone, not Everyneo lol

[true vortex]

Hey so i have a shooting mechanic set up with do once, then a timer that resets the function to fire again semi auto style but ive noticed that for some reason like the gun jams every once in a while?

I feel like if you spam the mouse click too much it gets jammed up

which doesnt feel great

[subtle shoal]

I have two versions of my editor utility blueprint, one that uses Get Asset and one that uses Load Asset to get object references. Both functions are producing null on valid inputs. Has anyone seen this issue before?

Blueprint Original

Blueprint Alt 1

[frosty heron]

A timer will reset the tine again if it's called again before the time expire.

Why not have like a cool down inside the weapon?

The weapon should handle it self if it can fire or not. You can keep clicking and request to fire but the fire only gets executed if conditions are met (not in cool down, not empty, etc)

[astral wyvern]

I have an input asset that gives me a vector 2D. And my player has some states, and I want to use those values differently (or even ignore them) based on those states. Is there a way to do that?

[steel star]

what you want is probably a delay node not a timer

[frosty heron]

Switch statememt on your enum.

[astral wyvern]

I have that for the different states

But the thing is, say I press A or D (horizontal), it works

If I press WS, it also works

I the case where I press WS, I want it to do something else

Depending on the context (player state)

[frosty heron]

Shouldn't you get different values when pressing WS

You can check the value and do something accordingly.

For movement, you would probably get something like

0,0 1,0 -1,0 0, 1 and so on

[steel star]

well, holding both opposing keys would negate each other so the axis value would be zero

however hes unlikely to be actually handling input in a blueprint like that

if what you need is the actual key states not some cute vector, bind to the individual buttons as bools, and do all the work yourself

[frosty heron]

Yeah, if you press a and d at the same time, you wouldn't want your character to move? Or maybe some people do, I dunnoe

[dim halo]

will an aic override the owner reference in a spawn actor node. i.e if i set the owner for a spawned actor to be self will it always be overidden by the aic or is there a way around this

[astral wyvern]

Can you link me a resource for this? I’m not familiar

[frosty heron]

What is aic?

[dim halo]

A ai controller

[frosty heron]

Have you actually checked if it's override? Do a print string on owner

[dim halo]

I did

It’s printing the ai controller

[frank locust]

Few questions, main goal is to set my spawns at each of the 4 corners of the produced grid no matter what width and height is give so I could then set up randomized paths from those spawn points to the 'homebase' at the center. I knew I would need help setting up the pathfinding in blueprints, but i had no idea setting up the spawns at te corners would be so difficult. it wasnt as simple as using the 0-1 phase to track what tile was being placed, and does multiple branch statements in blueprints drastically slow down compile times?

[dawn gazelle]

Compile times aren't really a concern. Runtime performance could be. That said, banches themselves aren't really so much the problem as what could be being used to determine the logic to branch.
Like a bool connected to a branch is simple as it's almost like you're checking a single bit if it's on or off. If you have a ton of math and calculations that then lead you to a true/false, then all that math could be problematic at runtime, especially if it's done frequently (like on fast timer or on tick) or even hundreds or thousands of times within a single frame.

What you have overall looks fairly simple for your branches.

But, one of the problems you would definitely have is that you're using == with floats.

Floats are notorious for not being accurate.... You're better off using "nearly equal to"

[frank locust]

yea i just had to relaunch the editor, everytime i would make changes to the >= checks compiling would take forever, and when i changed the row and column amount the engine pretty much hung up. but it seems to running fine now. but yea with those == checks, even if they arent dead on, the position i was expecting the resulting placement of the spawner was still way off when i used .25 and .75 but .00 and .99 did work for the first and last corners no matter what size i made the grid

[late gorge]

is it possible to easily put the engine into 'frame-by-frame' mode? i want to see an animation play out in the game frame by frame for collision purposes to see if it's failing because the mesh is just moving too quickly or something else is the problem (collision detection is based on a repeated event firing traces, not collision of meshes itself)

[lunar sleet]

Breakpoints

For animation idk tho

[late gorge]

i've tried that, it really doesn't help since the visuals don't render

this is the best i can get with a 0.015s setup, going even lower on the delay is not helping anything (just above 60fps which is 0.01666 iirc)

that blue line is where it would ideally be hitting, but when the swing gets going, it just goes too fast

i would prefer not to have to swap to a collision-based approach since it's critical code and wouldn't want to spend a week or two on this :\

[spark steppe]

set the time diletation to something lower!?

that should render everything slower

[lunar sleet]

I think sweep does the collision between points check for you no?

[late gorge]

that doesn't change how it's gonna work in the end

only idea i have so far is to keep a history of points every tick and increase the fidelity of the collision check

or some other mathy solution to increase the fidelity

but again, looking for clean and simple if possible
note game is singleplayer, replication is not a factor

[lunar sleet]

Still not sure what the failure is

[late gorge]

the blue line is what it should ideally be hitting

it's very inconsistent in actually hitting enemies

that furthest out line of traces should ideally be a circle

not a jagged line

well every line of traces

is my only realistic option to actually just attach a collision to the mesh? coz that's a nightmare for other reasons

:/

[lunar sleet]

Such as?

[late gorge]

the collision setup as a whole is completely busted, 3 tons of duct tape doesn't begin to be enough to hold it together
(i was not the one setting it up)

you add a collision to the weapon, the player begins flying 😂

and not in a controlled way

anything other than improving the fidelity of this check is basically weeks of refactoring

[lunar sleet]

There are collision channels

You can make the weapon and player ignore each other

[late gorge]

yeah... and there's a lot of code i'd have to change if i added a new one

see above

weeks

[lunar sleet]

A new what ?

[late gorge]

a new channel

the existing collision channel that's used would have to get cleaned up

suffice it to say it's set up wrong from the beginning, aight?
character capsule is freaking pawn if that gives u any indication 😂

[lunar sleet]

I mean, refactoring is life, but I can understand not wanting to spend weeks to fix something

Tbh I deal with collision-based issues daily lol

[late gorge]

yeah overall it's not too big an issue, the setup is stable, but there are some really whacky edge cases that i'm tackling now

afaik actual collision components do sub-frame checks right

so it should work in theory?

[lunar sleet]

Couldn’t tell you 😅

[late gorge]

i mean i don't see collision components just randomly go through walls just cause they go... fast... ish

[lunar sleet]

Uh

So

[late gorge]

if they go real fast then yeah, they'll phase right through

but not at the speeds of these animations

[lunar sleet]

Hit detection is iffy at high velocities. Overlap is better if anything

[late gorge]

yeah i mean it wouldn't be blocking collisions

not going for ragdolling or anything

aight, guess im strapping in for a fun ride :(
gotta fix up stat scaling and this ahead of combat design 😂

or rather combat tuning

already got a design, just gotta tune in the numbers and the attacks to connect properly

[hallow wyvern]

Aquarium of power

Salute, please tell me how to create:

only that part of mesh 1 is visible, which is located inside the volume of mesh 2

I created two materials for meshes and a material for PostProcessVolume

It seemed like it would work, but no, maybe you know another way, or see my mistake

Thank you very much to the enthusiast who responded ✍🏻

[lunar sleet]

Try #materials

[balmy viper]

Does anyone else have a problem when debugging loops, where if you have a breakpoint inside the loop body, and hit 'continue execution', it does not break on any further loop iterations?

[balmy viper]

Hitting either of the circle buttons skips the rest of the loop iterations. Can't be just me, surely

[lunar sleet]

Try the right arrow? 🤷‍♂️

[rose crest]

F10 or F11

[balmy viper]

those only step one node at a time

I wanna run til the breakpoint is hit on the next iteration

that's what breakpoints are for

[lunar sleet]

Or sorry second down arrow

[lunar sleet]

Really? 🙂

[balmy viper]

responding to the f10 f11 guy 😉

[dusky cobalt]

Is there any faster way to get ''values'' from map if I know that the map will only have 1 key all all times, the key may change though or maybe I should just put key to be default 0 and use values since they are mostly what I care about. I guess no.

[balmy viper]

Actually the last arrow (Alt+Shift+F11) more or less works, so crisis averted

[lunar sleet]

Haven’t had this issue tbh, maybe restart engine for sanity check?

Weird, that’s step out of

[balmy viper]

it's still a bit weird though, quite different to debugging c++ in vis studio

[dark drum]

If there's only ever going to be one entry in the map it sounds like it's not a map you need to be using.

[rose crest]

I can't see option to skip until next debug breakdown

[thorn yacht]

Hello everyone! (reposting that message from the #ue5-general )

Recently I started to have issues with my packaged ue5 game.

I send it to several people to test it out, and some of them just couldn't play it because main level wouldn't load. There is a main menu screen with button that just opens certain level. When they press it, they encounter infinite loading screen, and in the task manager the game is 'not responding'.

The logs doesn't show up any errors or any useful information about level loading.

My questions: have anyone encountered the same issue, and if so, how do you solved it? There is any way to troubleshoot issues with level loading?

Thank you in advance for help!

[balmy viper]

Normally you would just continue execution, because it would then break again when it hits the same breakpoint, because it's in the same loop .... this is not working as it should

[dusky cobalt]

Lol, right. I can just set the struct... I feel stupid 😄 thanks!

[dark drum]

How are you loading the levels in the menu screen?

[balmy viper]

I haven't had this specifically, but if I were you, I would put in a bunch of tracewrites, to give you an invesigative lead on where the execution is successfully progressing to, and where it is getting stuck

[thorn yacht]

By 'open level' node

[dark drum]

You need to show how your loading the level. The nodes themselves work perfectly fine so we need to see how your using them. (also there's two open level nodes.)

[balmy viper]

does it freeze during execution of 'OpenLevel' node, or is there more execution of your code after that?

[lunar sleet]

Infinite loading screen…isn’t that a Bethesda “feature”? 😛

[thorn yacht]

Here is the example of the end of the log which was sent to me. I will open bp and show you screenshot

The funny thigs is that for some people (including me) everything works fine, but some of them encountering issue. And it happens for both high- and low- end PC setups x)

[dark drum]

Do you have ?'s in you're map name?

[thorn yacht]

No..

Here is the evidence x) I think those ?? are just separators for level loading tags

[dark drum]

How are you handling loading the level?

[thorn yacht]

Here is the BP code

[thorn yacht]

I just sent BP code below

And people encountering level loading issues in both cases : (

[dark drum]

I don't know if these are causing your issue but either way. This circled stuff should be moved before you attempt to load the level. From my understanding, load level is blocking so will stall the game until loaded. As you're not level steaming, the current level will be destroyed when the new one is loaded meaning those two nodes won't get called.

[dark drum]

Also, I'd recommend using this open level node instead of using the name one unless there's a reason to need to use a name to specify the level name.

[glossy cloak]

Does it work fine in PIE?

I'm wondering if your levels aren't being packaged.

[dark drum]

Other than that, I can only assume there's an issue with the levels not being packaged correctly. (it can happen when you don't use the 'By Object Reference' version. If you need to keep using the by name one, you'll need to check you're package setting to make sure you're map folder is included correctly the relevant maps are packaged.

[thorn yacht]

Yeah, and it works well in packaged game for 50 % of people x)

[thorn yacht]

If levels wouldn't been packaged, then why for some people game works fine?

[glossy cloak]

Oh okay. Then that's not the issue.

Is it a really large level?

Also is the game multiplayer?

[thorn yacht]

This is quite large level and not multiplayer

[glossy cloak]

Could it be that some of your players can't run it or their machines are just taking a long time to load it?

Not responding in the task manager is a red flag though...

[glossy cloak]

Oh I missed this message.

Is it happening 100% of the time for the players that can't load it, or only sometimes?

[thorn yacht]

Yes, always : (

[thorn yacht]

I've done this code according to plugin documentation, but I will try use level reference and shift nodes that way and let you all know if that helps!

[dark drum]

It might also be worth adding a few print strings just for the logs. One when the button is clicked. 'Starting World Load' and then in the level BP on begin play just add another one called 'World Loaded'.

It might give you a bit more indication as to what is happening if it continues.

[thorn yacht]

sure! I'll do that, package build and send to my people for testing!

[dark drum]

If it still happening it could be a sign that there's something happening in the level (most likely on begin play) that is causing the game to stall. If this is the case, you might need to add some addition print strings in places to see whats happening.

[thorn yacht]

Little update: someone who had that issue with loading just updated the drivers and restarted PC, and after that everything worked (except the fact that level loaded nearly 10+ minutes). Maybe this is techical issue, and there is some kind of bottleneck? But even that seems strange because we both have high-end PCs, and for me game works way better than for her (level is loading up to 5 minutes)

[dark drum]

Does anyone know if it's possible to double bind to an event dispatcher with the same event?

[dark drum]

Oof, even 5 minutes is a long time. Are you using 8k textures everywhere?

[thorn yacht]

No hahaha But I use large map from marketplace for showcasing assets, and this couldn't turn out to be good x)

[midnight kiln]

macros are neutered for not having local variables

[meager igloo]

How do I make a thing that checks if an Actor that is hit is the same as the player Actor,
so I can ignore parts of the same vehicle colliding with each other?

[frosty heron]

Use equal operator

[meager igloo]

ah ok thanks :3

cool, my car doesn´t crumble in the middle like a soda can no more when i hit a wall head on x3

[dark drum]

macros do have local var but they're just different to functions.

[frosty heron]

Cool

[dark drum]

removing features i see 😛

[midnight kiln]

yeah, they have anonymous variables or whatever they're called, but they're not very useful

macros in general are pretty undercooked

[dark drum]

How so? You either need a local var or you don't. Also what were you trying to do?

[midnight kiln]

you have to drag the pin allllllll the way over to each place it's used in the graph unlike proper local variables

it helps with perf by not reevaluating expressions each time, but if my main goal was perf for this macro I'd use C++. Primary value of local vars in blueprints is organization

[meager igloo]

well it still does when another car hits it from the side, don´t worry xD

[dark drum]

The primary goal of local vars is storing temp data while you're performing calculations. Local vars in functions reset every times it's executed, macros retain their value so can be used across different calls.

The only thing that stops me using macros more is that children can't use macros created in it's parent.

Does anyone have any idea while my widget is receiving the event dispatcher call twice?

When it's created it binds to the 'OnQuanityUpdated' event dispatcher on my item object. When it's quantity is updated it calls the event dispatcher so the widget can update itself (and trigger an effect) but for some reason the bound event gets called twice.

Edit: I figured it out. I don't unbind the widget when it's removed. :S

EditEdit: I had another widget bound to the same item object that just wasn't visible (uses the widget stacks) so despite having the same name, they were actually different widgets.

[outer quail]

I have a weird issue going on, the packaged game would crash on my computer that I used to make the game, but it run fine on my laptop. The laptop specs is from 2018 while the computer have better specs with rtx3060

[austere mirage]

i need help with ue4

[thin panther]

That ain't a lot to go from

[austere mirage]

sorry g

so i have a overlap event

it says does not have valid matching component

[thin panther]

Sounds like the overlap was an event for a specific component, which has since been removed

You want to either add the component or use a generic on actor begin overlap

[austere mirage]

need a screenshot

[frosty heron]

Yeah, go post your screen shoot @austere mirage ?

[dusky cobalt]

Is it ok to call events like that? Because right now it doesn't work. I basically need a delay after setting it to false, so it waits 5 seconds, and after 5 seconds start neutralizing point (each 0.5s) but nothing is happening?

[south raven]

hey everyone I'm trying to make a box collision activate if user presses a button, how can I achieve that? For example there is a box collision on BP already but I want it to be OnComponentOverlap only if user presses a certain key

[frosty heron]

remember that calling Set Time before the timer expired will reset the time

so if you keep triggering that Set Timer before 5 seconds elapsed, it will never be called.

[frosty heron]

read the warning (and post it if you want to ask about it)

[austere mirage]

whats a matching component

[frosty heron]

post the error log

[austere mirage]

im new to ue4 whats that

compile results?

[frosty heron]

post the entire screen

don't crop it

[austere mirage]

its very blurry

[frosty heron]

you are still cropping tho

the warning message is at the bottom of the blueprint window

[austere mirage]

im using snip

[dusky cobalt]

Yeah, it was the issue. I didn't notice the other event was still calling it, I needed to call Capture Point once (that is what I though I was doing), but I forget to disable other event that was triggering it each 0.5s. Thanks

[frosty heron]

does snip prevents you to post an entire screen?

not fammiliar with the software

[austere mirage]

@frosty heron

[frosty heron]

if you don't see it, select Window -> Compiler Result

[austere mirage]

im using ue4

[frosty heron]

so what

[frosty heron]

it's really hard to see what's where when you crop like this

anyway you don't have a matching component for that overlap event

[frosty heron]

reason could be that you either delete the component that trigger that event, or you copy paste that from somewhere else.

[austere mirage]

in my case what triggered the event

[frosty heron]

See here, there is no BulletCol

[austere mirage]

its from a diffrent actor

[frosty heron]

you can't copy paste the event like that from another actor

hence the error

handle the event collision in what ever actor the component lives.

[austere mirage]

i dont want to apply damage to my bullet actor

[frosty heron]

then don't, but I want to take this into the context of what the problem is

You are calling event overlap on component that does not exist in the actor you paste the node in

[austere mirage]

yes

[frosty heron]

hence the error because there is no matching component for the overlap event you pasted

[sweet silo]

hi there how can i properly hide a character for some time ?

[frosty heron]

Set Actor hidden in game or you can Set the vissibility

[sweet silo]

the hierarchy is too complicated to do "hide in game"

[austere mirage]

your not speaking the english langunes

[frosty heron]

what's complicated about it?

do you want to hide just some component or do you want to hide the entire actor?

you can propagate the change to childrens

[sweet silo]

no the entier actor

[frosty heron]

then do it on the actor level

not component

[sweet silo]

wdym sorry

[frosty heron]

this will hide the entire actor

[sweet silo]

oh ok thanks

[frosty heron]

in the game view only tho

[sweet silo]

thanks a lot that's what i was missing

[south raven]

hey everyone I'm trying to disable/enable collision when user presses key. I've tried to do something like this but for some reaon it doesn't deactivate at all. What I'm trying to do is disable the collision of Capsule collision if player is not pressing a specific key. And activate the collision once pressed the key until released.

[frosty heron]

@sweet silo you can also do this

[sweet silo]

but ti's only the capsule right ?

[frosty heron]

Check the option at the bottom where it says Propagate to Children

[sweet silo]

oh awesome

[storm stream]

Is there any option to modify Data Table values in blueprints?

[sweet silo]

any idea why this wouldn't work in game?

[storm stream]

if u want to hide it, make it true

[sweet silo]

no i want to unhide sorry

but it doesn't unhide

[frosty heron]

check the vissibility settings

for the component to be visible, it has to not be hidden in game and it also need to be Visible

during play in editor, you can eject from your controller, select the target actor, select it's component then check it's vissibility value.

[sweet silo]

ok thanks ah ok didn 't know that

[frosty heron]

I don't think so, but it's a pure guess. My only experience is changing value of Data Assets in editor, and that one is still possible in blueprint

You mean editor time anyway right? You are not suppose to change DT in run time

they are read-only

[storm stream]

Eh i want to create some sort of data with game state values. And the problem is that i need a lot of variables in this so arrays is so slow and laggy if i have 10.000 + , data tables is a lot faster so i choose it

and the problem is i cant modify it xD

or at least I don't know how yet

[frosty heron]

@storm stream I would totally do the heavy operation in cpp 😅

Blueprint and large data don't go hand in hand

[worthy jasper]

You can edit data tables at runtime and “refresh” them but it’s really just not a great idea and doesn’t work well. DT are really suppose to be you set them in the editor and read from them

But yeah with that much data of course blueprint is choking haha 😂

[frosty heron]

Yeah you can, I actually remember doing it by getting the row handle

But that's still in cpp land

[worthy jasper]

true

[storm stream]

search through array in cpp with a lot of variables is only option?

[worthy jasper]

yeah I’ve seen a pack do it but again even in that pack it’s meh

[frosty heron]

Looping thru array in bp that large is recipe for disaster but I never try it my self

@lofty rapids did tho

And it's 200x faster

[storm stream]

i tested it and for 10.000 + has mini-lag

[worthy jasper]

Yeah CPP is generally better for number crunching

[storm stream]

(blueprints) xd

[worthy jasper]

Hence the whole use blueprint for what it’s good at and CPP for what it’s good at

[storm stream]

so its time to learn some cpp

[frosty heron]

I would say you are dipping your toes to what blueprint is weak at

You should tbh, even knowing some basic will give you advantage

I just started learning my self

But I could do what blueprint can't, there's just soo many feature not available in bp.

You can chose to use blueprint for the most part and cpp just for the part that you need.

[storm stream]

i know some basic stuff so create a event with searching through array should be relative easy for me and expose it for BP but still i prefer only blueprints 😄

[frosty heron]

Sure, personally tho. My old game is pure bp. I'm not doing that anymore ever again.

[austere mirage]

sorry @frosty heron for not coparayed i fixed it

[steady night]

hey guys i need some help with linetracing

i need to trace faster

https://gyazo.com/ace55010f95233c9bf1f3cf03f657ba4

im "unpausing/pausing" on anim montage notifier

but 0,001 isent working or i need it to be faster

what are my options ?

[frosty heron]

@steady night you can't trace faster than your FPS, already give you the option yesterday. Trace Backwards

[steady night]

wait what

u did .O ?

[maiden wadi]

Trace along the path instead of at the path segments.

[frosty heron]

this is one of the way

[steady night]

so basicly 1 trace along the whole path instead

[maiden wadi]

Not quite.

[steady night]

hmm

[maiden wadi]

Like what Cold posted.

[steady night]

hmm

[frosty heron]

You can use sockets imo

When you trace, you also want to trace to the last frame position

[maiden wadi]

It ends up being more like the green line than the red ones.

[steady night]

hmm

[maiden wadi]

This is also costly though too. So decide if you really want this kind of precision. 90% of games just use a set hit area.

[steady night]

so basicly save previous trace and trace between that and new

yeah i mean i could just increase the radius of the sphers that would "solve it" but would be fun se it near perfect

[frosty heron]

With the way you doing it, it's not gonna work on low fps machine

My old game use the same system, everytime I lag, the enemy just dodge my slash

[steady night]

hm

[frosty heron]

Just do as authaer illustrate

[steady night]

hmm

trying to

how would i trace like that :/

traceing from endpoint to end point instead basicly ?

[frosty heron]

From the visual that I see, it's as simple as tracing back to last frame location

I would use sockets that live in the weapon

[steady night]

i have

and i save the trace end/start

oh right

[frosty heron]

You just build on top of what you have

Implement the backward trace

To compensate for the gap that is left

[vale arch]

Can someone help me how to make emf react on ghost ?

[frosty heron]

What is emf

Also try to grab pen and paper , that usually help formulating what you need

You can translate what you want in plain English to codes/logic

[vale arch]

Equipment for measure Elektro magnetic phenomena

When you are closer to ghost emf equipment start light more and more

[frosty heron]

Event tick, if distance to actor < range

EMFvalue = EMFvalue + (value per second * delta second)

And just subtract if you want the opposite effect when ghost far away

[steady night]

https://blueprintue.com/blueprint/np0lhr6z/@frosty heron

i dont get it

[frosty heron]

I can't hack it for you, a gacha game I'm playing is pumping new character

[steady night]

oh since i store it as a local variable it dosent get saved for the next instance right :/?

xD

https://gyazo.com/04cd8b4729901e506acb0dcb2910ac12

gues its enough

could lower the "end point and increase radius to make it get the holes inbetween

the first one tho hmm

since it being set the 2nd trace its tracing towards the lateast position how would i clear that :/

[vale arch]

For me it’s working but I have problem it’s not in real time I have in details default where is Update EMFLevel max detection actor and emf level but I need make it in real time the light changing by how far is the actor

[final berry]

Hello! I got this matching system which works great, after I do a move it checks for matches by firing a custom event, and removes those etc.
However when (like at the end of the video) if the new gems fall in the place that it instantly creates a match it should also fire that event.

So in summary: What is a good way to check if the board is still/in idle position or however you want to call it. I tried the velocity on z axis, but it seems fidgety, also because of small movement glitches that are happening when rotating the gems (you can see it ever so slighty compress and bounce)

Maybe I should not use actual gravity is now my thought and simulate it by moving gems down till they hit something etc, but then again I like the fluidness of how the new gems are added now 😅
So yea I'm torn, any suggestion would be appreciated 🙂

[vale arch]

My bad

But I have correct

But I have problem with this

[thin panther]

now that is very confusing. Why one on a phone and the other on the pc 😄

[vale arch]

I don’t need in details update EMFleve I need to make automated by how far is the actor

How to make the update emflevel set automatic real time ?

[steady night]

need tips on solution

s

[reef elbow]

for me a diagonal sphere trace worked fine, i have the sword, the tip, and a trace from the tip to the next frames bottom vector

[true vortex]

I tried that too with a do once to make sure there’s no chance of retriggering the delay and the firing is still not consistent if you click too fast it jams

This is inside the actual weapon blueprint and the mouse click just calls that weapons fire event

[frosty heron]

you don't really want delay node for gameplay context , especially for firing weapon

[trim matrix]

Hey everyone,
I am having an issue with a Mechanic of mine, where the Player spawns an Enemy which runs away from you. If I place the Enemy in the Level, it works but if I spawn it infront of me by pressing R, it wont more at all. Does anyone know why?

[astral wyvern]

What do you mean by won't work?

[trim matrix]

The Enemy first freezes

[astral wyvern]

It won't spawn or it won't have behaviours?

[trim matrix]

The animation works and it spawns

[maiden wadi]

Placed in level usually creates an AI controller for it. SpawnActor does not create an AI Controller. So make the R do SpawnAIFromClass.

[trim matrix]

Its stuck in place as if there was noo nav mesh

[trim matrix]

I think I used SpawnAIFromClass

[maiden wadi]

That is usually the main issue with spawning an AI vs dropping it in the map, is that a few spawn methods don't create AIControllers. 🤷‍♂️

Could try projecting it's spawn location to the navmesh if you're not.

But I'd double check that it's getting a controller.

[trim matrix]

I have a feeling that the Event might be the problem

I am using a BeginPlay Node

The placed ones react but the ones I spawn after starting the Game freeze

Maybe the ones react to the event that are actually there when it starts?

[maiden wadi]

Are you using BTs? Or what is the enemy logic running on?

[trim matrix]

Sorry I dont really know much abt UE Blueprints. Can you specify what you mean by BT?

This is the Blueprint Setup which I have followed

This spawns the ai infront of the Player

[spark steppe]

BT = Behavior Tree

[maiden wadi]

Yeah. So beginplay is the issue here because this character won't have a controller at beginplay when spawned into a level that has already began play.

The reason being...

Place actor on the map:
Map loads pawn
initialization creates controller
Beginplay runs at some point later.

Created after beginplay:
Character is spawned.
Beginplay runs on character.
Controller is spawned
Controller possesses character.

[trim matrix]

Is there a Event Node that gets the Blueprint to run when it gets spawned/placed in the World while it plays?

[maiden wadi]

Beginplay.

In reality though. You probably want to call this chase logic in the... Possessed? event

I don't remember the name specifically. But there's an event that'll run when the pawn has been possessed and it's controller is valid.

[limber dust]

is there a math formula or node for getting the angle a character hits something at

[dawn gazelle]

Hit results have an "impact normal" which is a normalized vector. You'd be able to compare that with other vectors (like the actor forward vector, Up vector, Right vector) to get an understanding of the angle.

[limber dust]

That does help a lot I did not realize one of the 50k hit results was for impact normal lmao

I can get it from here, thank you 👍

[winter totem]

Hello, can someone please tell me why this only loops for 3 times instead of 5?

[trim matrix]

Any advice to create a overlay like this?

[maiden wadi]

Unsure which overlay you mean exactly? The green areas?

[trim matrix]

Yes, I don't know how to name it

[maiden wadi]

• Index zero
• You have 5 children. You remove one and have four
• Index one
• You have 4 children. You remove one and have three.
• Index two
• You have 3 children and remove one and have two.
• Index three
• Invalid to run, you only have two widgets

TLDR: Remove things by iterating over the array backwards instead of forwards.

[thorn yacht]

An a update about loading levels: I tried both your suggestions and they do not seem to work : ( I think now that this is an optimization problem, so I tried to use World Partition and load only part of the landscape. And this doesn't work too: loading times are still too slow...

[winter totem]

That's not correct tho, I am always removing the first child

Even if I use a For Each Loop and remove child by reference it doesn't work

[maiden wadi]

It is correct, and yes, you are.

[dark drum]

how big is the size map for the level?

[winter totem]

The code works perfectly fine if I just replace getchildrencount by 5

[winter totem]

And the code works in C++ as well ..

[maiden wadi]

Because you're misunderstanding the logic of the foreach loop. Look at it internally.

Every loop it'll check the input. Every loop it'll check how big the array of children is. Every loop that gets smaller.

[winter totem]

Wait it does that in BP?

[maiden wadi]

Do remember that those are macros, not functions.

[winter totem]

It checks input every run?

[thorn yacht]

3.8 GB... I guess that's a lot? : |

[maiden wadi]

It does. This is why I frequently throw a tantrum about Epic not making array output function automatically impure.

[winter totem]

Huh well that is really weird and makes a lot of sense xD

Any idea where I can look at the code for the foreach loop? I am not very experienced with BPs and just use them for simple stuff

[maiden wadi]

Just double click it.

Should open the macro lib it's in.

[winter totem]

That's great, thanks a lot for your help! :)

[dark drum]

To load in one go, I'd say so. How long is it taking to load?

[wraith loom]

Do I really need to make a macro just to get a reference? Surely there's an easier way to do this

[maiden wadi]

What do you mean to get a ref? Most softclass inputs allow you to specify it right on the function.

[thorn yacht]

1 and half minutes if I use World Partition. But on map with WP size map says "at least 700 MB"

[dark drum]

For the slow loaders, are they running off an HDD or SSD?

[thorn yacht]

I've asked them just now. But I myself ran the game on HDD and wasn't the one who got game loading more than 5 minutes (when some of them waited nearly half of an hour 😶 )

Yet the test I just made was on SSD (with 1.5 minutes)

[dark drum]

I still feel that's too long. Do you have anything happen when the level loads?

[maiden wadi]

3.8 gb sizemap is a little brutal too for a map.

Feeling an 8k texture overload there.

I'm also hoping you mean that is sizemap and not the UMap itself file.

[thorn yacht]

Of course! I use Virtual texture for map, and all the textures are no bigger than 2k. But the map is nearly 6x6 km..

[dark drum]

A fully populated with assets 6x6km?

[thorn yacht]

Not quite. Most part is just big mountains that serve as world border. Yet there is some foliage on the main part of the map + some buildings

I know that using map from marketplace was a bad idea x)

[dark drum]

can you show a picture? It might be that you need to dig heavily into level partitioning or level streaming but as Authaer said, you'd probably need to profile to be sure.

[maiden wadi]

Would need a profile to wager what the issue is, honestly. I mean that's a good sized sizemap. But 3.6 gigs shouldn't take over a minute on an SSD.

And yeah. Level streaming is a necessity for any map of that size. It's hugely wasteful to keep that much resident when the player is like minutes travel time away.

[thorn yacht]

I see than I potentionally can just cut out some parts of the landscape, but I'm already tried to use world partition and loading only small chunks. Yet 1.5 minutes to load...

[maiden wadi]

IMO I would just run an insights profile. See what is taking that long during the load.

Cook game. Open Insights. Open game. Load map. Close game.

[thorn yacht]

Sounds reasonable! I'll try that

[dark drum]

I need to learn the new unreal insights. I went to use the old method a few weeks back and it wasn't there. lol.

[patent thistle]

hello, has anyone made a dialogue system within ue5 and would be able to help a very confused person 😂

[eager python]

Anyone able to explain what causes this "static" effect on this mesh? Closest I can find is that it's fixed by switching to non-virtual Shadow Maps, but it sounds like that's also going to lose me some performance. I can't figure out how to fix it so it doesn't mess up in the Virtual Shadow Map.

I guess on the same topic... Are Virtual Shadow Maps even what we want to be using at this point? Or am I grieving my future self by disabling them?

This texture is from the Medieval Dungeon project on the Marketplace.

[thorn yacht]

Trouble come out of where no one expected: from the RecastNavMesh...
It's generation set to Static and GenerateNavigationOnlyAroundNavigationInvokers is checked.

[maiden wadi]

Yeah.. we had some issues with early navmesh gen on Red Solstice 2 that Kaos had to fix. Kinda weird that it would cost that much unless you have a ton of invokers though. AFAIK we don't use invokers, just a dynamic nav mesh.

[thorn yacht]

So how do you solved that problem? Because now I have no ideas at all...

[dry sleet]

Nav invokers I've known to be pretty bad overall.

I think they changed them a little in 5.4

But previously I believe the advice was not to use them, instead preferring nav mesh streaming.

[thorn yacht]

Hmmm... So basically I need to cut one big navmesh into small chunks and then load/unload them when it's convenient?

[wraith loom]

Well I want a macro to output a soft class ref depending on it's input. This is the easiest way to get a soft class ref that I've found so far.

[dry sleet]

I have no idea how it works with level partition actually, we haven't been able to switch to WP yet

I would have thought that it would be a considered feature in WP, breaking up the navmesh

Ask in #gameplay-ai maybe?

[dusky cobalt]

If I call Get Owning Pawn from HUD, will I get the Pawn that got Possesed by Player Contoller that owns that HUD when player joined game?

[topaz condor]

anyone know a solution to remove "Preview" from the shadows casted from lights

beside setting the lights to moveable

[trim matrix]

I just had to change this omg

[quiet violet]

im having a lot of trouble with an ai anim blueprint

[pallid nest]

hey guys, what am I doing wrong with this ? My intention is that a progress bar (skill image) changes based on a switch. The switch is fine but the texture is never displayed

[dry sleet]

It's there until you bake the lighting.

You can actually modify the engine material that prints that preview text, though.

1s

Or wait, maybe this suffices:

Hi, If you want to remove the preview watermark when you are in the editor view as you are working this can be easily done. Simply click on the Show tab in the viewport - go to Visualize and untick the Preview Shadow Indicator option.

[topaz condor]

yea i did that but when you play the game it shows in the render. ill try baking it and see if that does anything

[thorn yacht]

Yeah, it's a feature and it fixed my problem! There is one checkbox in navmesh that should be checked for that to work.

[dry sleet]

ah awesome

[ivory spoke]

I changed the GameState from predefined GameStateBase to Custom GameState. Now my Input and Camera Setup is resettet. So far I didnt change anything at GameState and it was the predefined Class. Any Idea what happens here?

ok if I changed parent class to gamestatebase it works again. does this have any impact?

[onyx cypress]

Any idea what am I doing wrong? i want my player character (Im using MotionMatching template) to be teleported when entering the trigger area, but it doesn't do anything

[onyx cypress]

It's just the trigger that seems to not work, cause the teleport function, when connected to "On game begin" teleports me straight away, and idk why

[frosty heron]

You are in level blueprint.
Check if teleporter have valid collision that can overlap with your character

If you do it on Game Begin then it teleport your straight away, what don't you understand on that bit?

It literary translate to, when game start, teleport me to this X location.

I suggest to read and understand what you are actually dropping to the blueprint graph

[onyx cypress]

I assure you, it has, i even made it bigger but it makes no difference. I made a simple trigger volume, that's what's being referenced in the level blue print

[frosty heron]

What I mean by valid, is not only the collision exist but it has valid setting to overlap your character.

Post your collision settings for both the character and the trigger.

[onyx cypress]

Oke, one second :D

That's my trigger

And that's my character

I see, none of the overlap is selected. I'll try doing that first.

Nope, that didn't help sadly.

[frosty heron]

@onyx cypress select the brush component of the trigger volume and go to the collision setting

You also have no overlap set at all

[abstract pebble]

can someone explain why this is only outputting true when there is a actor placed exactly at the box pos?

[onyx cypress]

I've set them to overlap but it made no difference, is there something wrong with my brush component in that case?

[frosty heron]

From your teleporter , print string, check the other actor and overlapped actor

[glossy cloak]

Because your box extent is the scale of the actor. So likely 1,1,1 unless you've manually scaled it up.

[signal bane]

Blueprint question on what the best way to do a thing is.
Say I have an Array of Strings and a Map of Structs.
I want to create an Array of Structs, where the String->Struct.

What is the best way to iterate through that and do it in BP?

[abstract pebble]

yeah i want it to go off when there is anything inside the actor

which it is a 1x1x1 cube usually

[glossy cloak]

Well the scale of an actor is by default 1,1,1, which means it's only creating an overlap box 1cm by 1cm by 1cm. So it's VERY small. If you want it to be same size as your actor you should get actor bounds, not the scale.

[abstract pebble]

oh ok

[frosty heron]

@onyx cypress I'm gonna assumed you want to collide with the character collision comp, is the setting you showed comes from the capsule comp?

[glossy cloak]

If you want, you can do a "draw debug box" and plug in the same parameters to visualize where it's at. Should help. @abstract pebble

[signal bane]

It feels like the best pattern is a ForEach loop, do a Map.Find operation, then branch and append if found.

[glossy cloak]

You want like an ID that points to a struct?

[signal bane]

Yep

[onyx cypress]

I manged to find the capsule component, turned on all collision on overlap and im falling through the map, which means that is the correct one, now I just gotta figure out with box is responsible for trigger volumes...

[glossy cloak]

@signal bane Personally I wouldn't use a map. They're kind of annoying to work with. I'd just make another struct with an ID and the struct variables. Then loop through an array of that and check if the ID = the one you're looking for. If so, do what you want to do.

[frosty heron]

Your trigger is set to world dynamic so your capsule needs to overlap the type.
And the trigger needs to overlap pawn

I would prob make a custom collision channel for the trigger

.
Map is great when you need a pair of keys and vslue

[signal bane]

The Map is a temporary structure. It'll be replaced with a custom more complex structure that handles fallbacks for unfound items

I think I'm probably prematurely optimizing for a thing I'll upgrade away from anyways

[onyx cypress]

My Character overlaps world dynamic and my trigger overlaps pawn, yet there is still no reaction :/

[frosty heron]

By character you mean the capsule component?

[onyx cypress]

Yes

As you see, worldDynamic is set to overlap

Ye idk, its almost 4AM so imma try stuff if you respond tmrw, thx for the help tho! ^ ^

[abstract pebble]

getting the bounds fixed it thanks ☺️

[frosty heron]

I suggest not using a level blueprint and create your own BP_TriggerVolume

drop the teleport and overlap logic inside BP_TriggerVolume and check the collision setting again to make sure it is set to overlap pawn

[glossy cloak]

The level blueprint is 90% of the time a bad practice usually taught in lazy youtube videos.

[onyx cypress]

Legit where I got the idea to begin with from

I'll try this now, im not sleeping yet

[glossy cloak]

There's a time and a place for it, but it's almost always better to build specific actors that you can reuse all over the place.

[onyx cypress]

I make that as an actor, I assume?

[glossy cloak]

A BP_Teleporter would be a really useful actor you could build that can have a bunch of variables exposed, like a connecting bp teleporter, or an exit vector location, etc. Then you can reuse that actor in multiple levels without having to recode it each time, for each teleporter.

Yep. Just a generic actor base class is great.

[frosty heron]

Yup, actor is the base for anything that have transform in the world.

[haughty sun]

Hey guys, UE5 noob here.

I'm struggling with accessing things from different places, I've watched some Blueprint Communication videos etc but it hasn't clicked yet and I'm spending more time trying to work out how to access a thing from x to use in y than actually learning my way "in general" around the engine.

I've found a couple of static/global variable assets on the marketplace which look like they would fix my current problem (until i can learn more about it and understand a bit more) and allow me to play around and actually build things, but I don't know enough to know whether they are problematic, cause performance issues or teach bad habits etc.

I was wondering if I could get some opinions from more experienced users on their thoughts on using these assets? I can link if required but they are called "Variable Access Library" and "TMG Global Variables" on the marketplace and say they allow you to easily access things from anywhere using soft references.

Apologies for the wall of text.

Cheers.

[frosty heron]

Marketplace not gonna help you understand the basic of blueprint communication, you are in total hopium mode. The only thing you shoul do is to learn it until you understand it.

[glossy cloak]

I wouldn't recommend the plugins/assets you're considering until you fully understand how the basics of blueprint communication works or, as you mentioned, you'll be learning some bad habits.

[frosty heron]

not knowing the basic, even if you buy plugins, you will still don't understand how to work around your problem

[glossy cloak]

Are you struggling to understand variables or just references in general and how to communicate between two actors?

[haughty sun]

Well I figured it would at least let me get access ot the things to build some stuff and play around, as right now I'm strugglign with even getting hold of the thing I need.

But I appreciate I will need to learn/understand BP Comms eventually

[frosty heron]

it is neccessary

[haughty sun]

I'm not very visual, so BPs are a stuggle anyway and just right now I'm stuck on getting hold of the thing I need to do the thing, so thought they might help for now as I learn.

[glossy cloak]

I teach an Unreal Engine summer camp to teenagers. Maybe I could help you get on your feet. Can I DM you?

[onyx cypress]

How do I "Drop" it inside of the BP_Trigger?

[glossy cloak]

Does your BP_Trigger have a box collision component?

[frosty heron]

you just write it again

[onyx cypress]

Aight I think I know what you guys want me to do, gimme a sec

[frosty heron]

Add a Trigger Volume in your BP_Trigger
Select it , look at detail panel. Go all the way down and select the one that says OnBeginOverlap and hit the + button

[haughty sun]

Hey @glossy cloak (love your devlogs btw) - I'm coming from languages/engines that allow easy use of global variables, where as UE seems to frown upon them so I'm struggling to get my head around where to store things I need global access to.

I've read I should use the Game Instance or Game Mode but that didn't seem to work and I still had issues getting a hold of the things I wanted to access.

As I said I'm new to BPs and visual programming isn't my strong point, I prefer to code (though never C++) so I think my issue is a bit of everything, hence wondering if those assets would give me easy access to things and let me get on experimenting to build stuff without getting bogged down in syntax (right now)

Yeah sure you can DM me, no problem

Also apologies if peopel were in conversation here and I just stumbled into it.

[glossy cloak]

No problem! I just didn't want to flood the channel with back and forth. I'll DM you now. I think you're probably pretty close to your "ah hah!" moment.

[frosty heron]

Global variables are evil

[haughty sun]

Yeah that makes sense re: flooding. Appreciate the DM!

So I've read since learning UE5 @frosty heron , but never had an issue with them elsehwhere as long as they're used properly.

[frosty heron]

it's not just UE, if you go to learncpp.com it will mention why global variable is evil

[haughty sun]

It's all just new and super frustrating, what would be one line of code is hidden behind multiple nodes and tickboxes and thats not how my brains works too well.

[frosty heron]

GameInstance lives throughout when you first start the game and when you close the game

Game mode is per level

[haughty sun]

Yeah I've been trying to store references in Game Instance, but still had issues.
I don't know enough to know why, so it's just got suuuper frustrating and I thought if those assets could tide me over that and make accessing things easier I could get on and experiment and come back to the whole comms thing.

[glossy cloak]

Yeah. I came from RPG Maker and an engine called Stencyl before Unreal so I was also expecting some global variables.

[haughty sun]

I agree it's not ideal - but for now to get over this hump...

[frosty heron]

You learn blueprint communication...

there is no shortcut man, it's not easy for me when I start too

watch it over and over, practice, fail, watch again

then it will click one day

[onyx cypress]

So, I crated BP_Trigger, added box collision to it, selected box collision, added "Begin overlap'' node, now I have a question - How do I get my "teleporter location" object here? cause It doesn't let me drop it, and if i set the coordinates it doesn't do anything.

[frosty heron]

right click on empty space, type self

self reffer to the object you are in, so in this case the instance of the BP_Trigger

or simply right click and type GetActorLocation

the target defaulted to self

[onyx cypress]

See that's what I wanted to do, as in my original level blueprint, but it doesn't let me select or reference an object in the scene

I have it selected but it isn't here

[frosty heron]

you are not supposed to use level blueprint. That @ss should be avoided at all cost for gameplay related stuff

[frosty heron]

You already got it

[onyx cypress]

I am not using level blueprint

[frosty heron]

self is BP_Trigger

leave it like that

#blueprint message
This is level blueprint

[onyx cypress]

But how does that know where to teleport me?

[frosty heron]

where do you want to teleport?

you are the one writing the code, you decide where to teleport the character

[onyx cypress]

To either this location, or this very object

But as i've said, it doesn't let me reference it in the BP_trigger

[frosty heron]

ofc not, the bp class doesn't know any world

they can exist in any level

[onyx cypress]

So how would you go about that then?

[frosty heron]

You were using level blueprint earlier which has no place at all for gameplay logic.
It's not reusable and the communication only goes one way.

So now, you need reference to the instance of what ever you are trying to teleport to

[onyx cypress]

Oh!

[frosty heron]

Create a variable in your BP_Trigger. Call it ActorToTeleportTo

set the type to Actor Object reference

[onyx cypress]

I teleported me to 0.0.0, so it works!

[frosty heron]

Make it instance editable and expose on spawn

[frosty heron]

yes, you can pass in any coordinate, why wouldn't it work

but if you want to teleport to the actor that you showed in the pic, then you need to pass the reference of that actor to your BP_Trigger

by doing
#blueprint message

watch blueprint communication video when you can

[onyx cypress]

Will do!

[frosty heron]

@onyx cypress you will still have issue too btw, right now anything that overlap the trigger will teleport the player character to some coordinate

even your enemies, or a box falling

because you didn't do any check,
you simply say, whenever my trigger overlap, teleport my player

so what you need to do here is , from theOtherActor blue pin, drag it and type cast to your bp player character.
On the top pin (succsess) hook your teleport logic

this way, the teleport will teleport the player character only when he is the one that overlap with the trigger

[onyx cypress]

I see

thank you :D

[weary ledge]

hello

[onyx cypress]

I can't seem to find this in the Variable Type

[lunar sleet]

Type only actor

[weary ledge]

im trying to create a camera that looks around by drag-right click. the blueprints are from the playercontroller and pawn, but im not sure if thats how you're supposed to use them. so far, if i test it, it works, but its extremely choppy and not nice to look at, i think the blueprint is inefficient. what changes should i make?

[onyx cypress]

and which one is it?

[lunar sleet]

@frosty heron Tbh I almost never create a variable of type actor manually, I always get the ref and then promote to variable from there or the subsequent cast

[lunar sleet]

First one from the Actor arrow

[onyx cypress]

Alright, I assume I do "Set" and then what?

[lunar sleet]

I think it’s best for you to watch the pinned video on bp communications here

It’s a bit long but worth every minute

[onyx cypress]

I will watch it tmrw, its currently 4AM so i just wanna get this done and go to sleep, im sorry if I ask too many questions

[lunar sleet]

You’re not, that’s just genuine advice so you can actually understand how it all works when you’re doing bp comms. Much better than stumbling in the dark imo

[onyx cypress]

I promise I will watch it, first thing i do when i wake up :D

[frosty heron]

in this case, the trigger needs to hold an actor reference to teleport the character to

my understand is it wants a trigger volume that paired up with an actor in a level

[onyx cypress]

Correct

[frosty heron]

but yea deffinitly dont roam in the dark

Matthew wadstein videos are good to walk you through with useful node

he also does blueprint coms video

[lunar sleet]

It’s also a good idea to let your brain rest, tho I can understand wanting to get something done

[lunar sleet]

Ah, doing direct pairing to an actor eh

[onyx cypress]

Fine, you guys are right, imma take a break and watch that vid tmrw

thanks for help both of you :D

[zealous moth]

I dunno if this is best handled with enhanced input or with the actual BP but how would you take the 2D vector for a gamepad input to lock it into different angles? like between -45 and 45, assume it's up and so on?

[lunar sleet]

Maybe deadzones?

[zealous moth]

no, this basically avoids small inputs past a value but if the player toggles an angle of 50 for instance, it will record it as up and right

[lunar sleet]

I mean enhanced input will give you a certain axis value so you can prly just clamp that

[primal berry]

I have a paper character , but the root component is still the capsule, so my question is: how can I fit it perfectly into the sprite?

[zealous moth]

in the end I used old reliable: the dot product

if abs(y) >=0.7, assume it is up or down. Then check if Y is positive or not. Otherwise do same with X

[iron delta]

so trying to get to know materials better and have created a simple pulse material which i apply to a plane and i'm curious if there is a way to control when a material like this "activates" so to speak. or would a better off creating something in a particle effect for better control.

[zealous moth]

You can modify the capsule width and height. worst case, use the original capsule as a movement base and make a new capsule on top to handle collisions.

[frosty heron]

@iron delta look up material dynamic instance and how to convert your variables to param

[zealous moth]

use a lerp between a static and a pulse and set the alpha either using a MPC or dynamic mat inst

[iron delta]

thank you, i'll have a look now.

[primal berry]

you meant something like that?

[lunar sleet]

Seems a tad overkill here but why not

[iron delta]

when you say static and pulse what do you mean exactly sorry? like one material that's static and with material with the pulse?

[iron delta]

is this what your talking about?

[lunar sleet]

Mind the double pings

Those are indeed the right nodes

[dapper forge]

Ello. Qustn. How do i fix char phasing through a horizontally moving platform?

UE is so bad with this, holy cow.

[iron delta]

is that for me? if so just forgot to put the image. apologies wasn't trying to be rude. also I'm just checking because I already am using them my terminology is just not so great. I'm just not sure what I should be tweaking to get the effect I want. not sure if its possible but i want the material to begin its pulse when the MI is created and it seems to pulse somewhat unpredictably.

[lunar sleet]

No need to apologize, just a reminder some people have discord on their phones so it can quickly become spammy 😀

[iron delta]

yeah good point that would be annoying.

[dapper forge]

easy as that i believe

[lunar sleet]

I think you’re missing the point

[dapper forge]

No, not really.

[lunar sleet]

Yeah

Anyways

[dapper forge]

there never will be "perfect" amount of notifications 🙂

[lunar sleet]

So it doesn’t work well if you just create the material like that to begin with?

I think what Zanet was suggesting was switching materials dynamically from the static version to the pulse

Which is done using the dynamic mat instance

If your current material is already an MI, then you might not even need to set the material again, just the dynamic mat nodes should suffice, but iirc that’s only if you’re changing parameters on the current one

[iron delta]

yeah, its probably just the material is not very well set up. i am using an MI. it seems to start half way through the pulse as shown above. other times it pulse through through perfectly. I'm super green at materials so my brain is a bit frazzled at this point. as i said earlier I'm not sure if i am going about this the right way,

[lunar sleet]

Ah you’re saying the pulse doesn’t originate in the same place each time?

[iron delta]

more it has a different pulse effect every time and i want to activate more like this. i know its only a subtle difference but it really bugs me haha

three smooth bursts

[lunar sleet]

I see. I’m not the best at #materials but you could try posting this video and a screenshot of your mat bp in there and see if anyone knows how to make it consistent

[iron delta]

Ahh i didn't see that there. new to the group, thank you i'll post there and see if anyone can help enlighten me. thank you!

[maiden wadi]

Presuming that you're using time to animate that. If so, when you set this. Set a float from GameTimeSeconds. Use that to negate from the Time node in the material, so that it always starts at zero.

[iron delta]

Ahh okay. I am. Thank you! I will give this a go now.

If I wanted to set-up an aiming/melee system very similar to classic RE2/SH1, what would be the best way to approach this with tank controls? I'm extremely new to making custom blueprints and haven't found anything similar to what I'm looking for online

[frosty heron]

A and D to rotate the capsule component

W to move forward in the actor forward direction

[iron delta]

I don't think I understood as well as I thought, is this what you meant?

[silent cape]

i already got the movement set up, works like a charm but im looking on how to learn to setup the combat system of it

[frosty heron]

Right click to make the character to aim and just line trace for the shooting part

it's gonna shoot the projectile forward depending on the actor rotation

or if you want to setup some auto aim like in Resident Evil,
When aiming -> If there is valid target -> Interpolate rotation towards target

[silent cape]

ooooh gotcha, thank you! def going to need to deconstruct what you said by myself for a bit so i can understand it haha but i think i got the general basis of it

[tawny patio]

Question, how do you activate and emitter back once it's deactivated. I have my player where if its hanging, I want the particles to deactivate and when it returns back to wall sliding, the particles activates again. Tq o/

I got the deactivate part down, but im not able to get it to reactivate again.

[lunar sleet]

It looks right according to this too https://forums.unrealengine.com/t/can-i-make-the-time-node-in-material-start-not-at-the-begin-of-the-game/388518/2

Only thing I could think of if it’s not working properly is maybe that clamp node you have right after. I couldn’t see what it was clamped to in #materials message , the resolution was a bit low clamped between 0 and 2.5 from what I can see now that discord decided to download the higher res.

Are you able to right click watch value in a mat bp? I haven’t tried

[iron delta]

correct, just something left in from the tutorial i watched. i actually was looking at that same page. i tried and didnt see the option. i'll keep playing. i did get consitently running just not how i wanted so i suspect its something in the material itself not playing nice.

[valid solstice]

all axis mappings are working besides these four anyone know why?

[primal berry]

scale is the same?

[dapper forge]

.5 .5 ?

Hello! I got this matching system which works great, after I do a move it checks for matches by firing a custom event, and removes those etc.
However when (like at the end of the video) if the new gems fall in the place that it instantly creates a match it should also fire that event.

So in summary: What is a good way to check if the board is still/in idle position or however you want to call it. I tried the velocity on z axis, but it seems fidgety, also because of small movement glitches that are happening when rotating the gems (you can see it ever so slighty compress and bounce)

Maybe I should not use actual gravity is now my thought and simulate it by moving gems down till they hit something etc, but then again I like the fluidness of how the new gems are added now 😅
So yea I'm torn, any suggestion would be appreciated 🙂

[dapper forge]

dont do graveety, ue graveety bad

use timelines and math for moving sttuff around

(its still stinking bad, but its better than gravity)

I'm trying to apply an impulse to physics objects that hit my character in the opposite direction to the direction of travel with half the strength of the force of the impact (to stop physics actors bouncing weightlessly off my character and give them a more realistic weight). Anyone know the best way to accomplish this? So far I've tried:

1. Other actor's velocity (normalised) * -1 * 2 (impulse location), 1000 (opposing force)
2. Hit Normal -> Mirror vector * 1000 (opposing force, hit location -> impulse location
   Both using the Add Impulse at Location node to apply the opposing force. Neither of these had the desired effect.

what happens?
