[slate fable]

https://sketchfab.com/3d-models/dice-d20-2d29634374eb4893a76a48132663d5a7 @gentle urchin maybe a better version to do the trace method. If I can get it working like you got it maybe theres hope to be able to get it solid! 😄

[gentle urchin]

dont give me a new model

im fixing it xd

[slate fable]

🤣 OKAAAAY XD

[gentle urchin]

only 3 faces missing

there we go

not my finest work but

it works with what i was given

So it basically tries to trace it, and if its hits a face thats above 19 (which is our highest face for the numbers) we just retrace

having rotated the trace a nudge,

and try again

[mental sequoia]

Just a random question: how do I print the x value of the transform value of an actor using an arbitrary event?

[raven mantle]

I'm trying to create a movement logic for a character in first person view, the movements and the jump work, but when I move my mouse to move my camera it works on the x axis but not on the Y axis, had Do you have an idea please?

[slate fable]

I look at that am still confused to be completely honest @gentle urchin like I see what it is and can recognize some of whats happening and I'd like to understand better how you set up the variables into the array of int's you got going on

[flat coral]

Do you mean like this?

[mental sequoia]

That’ll probably work. Thanks.

[gentle urchin]

I just manually mapped them

rolled like 100 dices

and got all the face ID's

and visually confirmed which dice value it had 😛

[flat coral]

You know about maps right? like the data structure? https://docs.unrealengine.com/4.26/en-US/ProgrammingAndScripting/Blueprints/BP_HowTo/WorkingWithMaps/

[slate fable]

I do not but I'm about to lol lemme read that

[gentle urchin]

it's a container with 'pairs' of values

a key, and a value

you use the key to get the value

so my key is the faceID of the mesh

and my value is the dice value

[flat coral]

Or even more basic https://www.youtube.com/watch?v=eMymKAFYaCs

[slate fable]

you got it to run the trace outside of each number so it doesnt throw it off

🤔

[flat coral]

Wait hold up why not just add a relative offset to the trace start so it always hits up in the corner of the side, rather than the center

[slate fable]

@flat coral a what?

[gentle urchin]

they're all rotated differently

or rather, some pairs of them are

[flat coral]

Hmm you could do the offset relative to the face then?

Ah! But you dont know the face lol. Fair enough!

[slate fable]

I'm going to try to implement this into a new dice blueprint now and read up on how to map it out and see what happens 😄

[red cape]

Could anyone help me with this please. Why is my character flying everywhere after ragdolling?

[lime basin]

why does this restarts every time i compile?

I set to 80 compile it goes back to 10 :/

[flat coral]

#umg . But be patient if you don't get an answer, I know my way around UMG and I have no idea what's happening to you here

[lime basin]

Thank you 🙂

[gentle urchin]

got some logic in pre construct ?

[lime basin]

yea

[flat coral]

that's it, that's why lol

[lime basin]

default value for box is set diffrent value that gets reseted

its not updating it to default values of width and Height that are 80 and 10

nvm I removed them it works now 😄

its a "fix"

[flat coral]

Alright team got a weird one, why the hell isn't this pawn moving when I use Set Actor Location? The actual logic for generating New Location is omitted due to complexity, but note the logs: Every tick, the current location doesn't change, despite the supplied location being different from it.

The extra-crazy wrinkle to this is I KNOW this function works. The pawn moves around as it should, UNTIL it does its jump attack move. It's supposed to resume normal motion after that, but it doesn't. It's calling the function, the values seem correct, but it just doesn't move

[faint pasture]

Show jump attack code

[faint pasture]

@flat coral when dk you turn physics back off?

[flat coral]

Excuse all the debug prints

You can even see that code getting triggered in the logs though

(Ignore the warnings, that's just because it's dumb and continuing to do wayfinding pulses while in the air and it can't find the ground)

[wraith loom]

Hello, whenever I put any kind of delay node into the body of a loop, the body of the loop only runs one time. Anyone know what's going on? The loop runs fine without the delay node in the body.

[flat coral]

I've also added a print that checks "is any simulating physics" on-move, it's false the whole time

[flat coral]

Heh, good timing, if you scroll up this channel, I think Squize had a pretty clean implementation of a loop with a delay earlier this morning

[red cape]

?

[flat coral]

Your instinct is right about this being the problem, though. I scooped out all the attack code and made it just turn physics on, then back off a moment later. Breaks it.

[cyan harbor]

I have a timer to decrease a progress bar and run some functions when its finished how can i make the timer go faster when a variable increases

[dire frost]

you cant. but you can make a new timer that is shorter

you can even use the same timer handle that you used to create the original timer at an attempt to make this spaghetti somewhat organised

[slate fable]

@gentle urchin lost trying to set up the bp lol that yellow SET node

trace offset?

nvm its a vector variable i think

[flat coral]

Alright got some clarity on my issue. Simply running this single function stops SetActorLocation from working whatsoever. Sweep, teleport, doesn't matter.

Hm might be because that sphere isn't the root component. Fixing that.

[glad sand]

Can someone show me a documentary for how to use state machines(not animation one, player state machine one. Like running, swimming etc)

even better how to make one 😄

been using unity for a while but know nothing in unreal 😅

[flat coral]

Do you mean AI behavior trees?

[gentle urchin]

Yes it is^^

So thats the offset that defines the radius really

Then we rotate it if our hit index is >19 (our highest index for a side)

[slate fable]

This is because I havent defined the int? I just copied the code as I saw it

[arctic cloud]

I guess you could do a branch and use the CanAttack boolean, and if the bool is true do X and if false do nothing / Y

[slate fable]

the attempts and *New Variable array are the things that need to be fixed in this case and being that I'm new I only have the slightest understanding as to where to navigate to fix this thing

[arctic cloud]

Doing it in Event Tick might (?, not sure) cause this, you are basically calling the retrace every tick in game. Try calling the event using a timer perhaps?

Also that do once in tick is basically useless.

[slate fable]

it worked for Squize earlier 🤷🏻‍♂️

[arctic cloud]

Try using a timer

[slate fable]

^

[glad sand]

@flat coral no for player itself

[arctic cloud]

Just saw it. You didn't connect the "AND" to the branch

[glad sand]

i dont wanna make 10 booleans and cheack each and every of them one by one

[slate fable]

@arctic cloud that fixed the error when running it but the line trace still doesnt show at least to debug, and I still gotta get those ints labeled so it'll be able to calculate a roll

[arctic cloud]

So just a quick question, you want to check if the player is swimming, moving, idling, etc?

[arctic cloud]

Also, in the "Rotate Vector" after incrementing the Attempts integer, in the Z Axis, it's 8, not 0.

That might be it

That's likely the reason why it doesn't read it. The video Squize provided you shows a line trace above the dice, that's likely your Rotate Vector Yaw (I think?)

[tight pollen]

will setting up skeletal mesh from DataTable be appropriate?

I want to use soft references

[slate fable]

Get Actor Right Vector not there thats part of the issue prolly aswell as the above 🤔

[arctic cloud]

Also, in the "Get Actor Location" and +, you inputted 1000, while Squize's value is 100

[slate fable]

aye!

nvm im looking at 2 different screenshots to compare my bps 🤦🏻‍♂️ thats totally on me

[rich ferry]

What's the easiest way to kill an actor but let the existing Niagara particles finish their lifetimes? I have a fire effect, and when it despawns all the fire and smoke just poofs out of existence instead of decaying naturally. It looks rather janky.

[arctic cloud]

Also, Squize uses a map for the "New Var", while you are using an array. That also might be an reason (unless you changed it)

[arctic cloud]

https://forums.unrealengine.com/t/how-to-make-particles-persist-after-destroyactor/258712

This might help you.

[slate fable]

I am using an array. I gotta figure out how to use maps in general and how to navigate getting to it etc. everything else seems to work as needed even spits a "You rolled -1"

the -1 comes from the >19 i think

being that I have no numbers plugged into the map for it to pull from

[glad sand]

Yeah I want to make a state machine

very scuffed one but as long as it works 😄

[arctic cloud]

that might be it?

And if he's walking do X, if he's falling do Y, etc.

[glad sand]

yeah thanks

[arctic cloud]

Just tested it with my character after falling from a set of stairs, the "Falling" action gets called. So that should be it.

[glad sand]

thx again

it really sucks when game is not working because I forgot changing one boolean in between some events and all 😄

[slate fable]

🤔

[arctic cloud]

You need to select your variable, and right next to the variable type, there's that little dot :)

[gentle urchin]

I found no dispatcher for when a physics item was put to rest

Otherwise that would've been used ^^

Could do it on some timer instead, but in a dice rolling game it hardly makes any difference

[slate fable]

Found it! 😄 how in the world do I populate it now? 🤣

[gentle urchin]

Like a regular array

Or container

Select the variable, check the bottom of the details panel

Or... the bottom half*

[arctic cloud]

Just add how many map elements you want

[gentle urchin]

Should be a + sign there

^

NewVar is FaceIDToDiceValue mapping

It was slapped together in a hurry so didnt bother renaming

[arctic cloud]

True. All that matters is for that to work :)

And have no bugs (optional).

[slate fable]

should only need 20 elements for the dice assuming 1 for each face? or did you watch how it fell each time getting the face ID then populating one at a time?

[gentle urchin]

Yes,

Only 20

[slate fable]

the offset accounts for not hitting the number right?

[gentle urchin]

The offset is there in case we hit the number itself yes

Which gives us the wrong face ID

8 degrees is just a random number

Could be 45

With 8 tries

Or 22.5 with 15 tries

[slate fable]

where do you see the face ID after you roll it?

[gentle urchin]

Hit result from the trace

[slate fable]

i see now

[twilit jacinth]

I am trying to make a laser emitter Actor Component to handle all the lasers on different kinds of actors in the game, but I am facing a problem of handling references and trying where to exactly put which functionality. Every actor has to send Niagara component reference upon Begin Play as well as their Forward Vector and Trace Start location, but trying to add the component to actor I have a bug report about missing Niagara reference on Deactivation. Not on the ACtivation node, but Deactivation Node

[arctic cloud]

Can you show your code please?

[twilit jacinth]

Sorry, I found a problem. It was because on this particular actor I put a SetLaserComponent function after all the BeginPlay nodoes and there was a Delay node there

Only problem I have now is laser firing in the same world direction on dynamic actors

I wanted to ask if it is in general a good practice to hold different functions capable of creating VFX or something unique to Owner in Actor components

[frosty heron]

If it's an ability I would probably use gas

[meager spade]

Maybe a dumb question, is there a way to find out exactly where a class is used in BP? The reference viewer only points me to an asset but not specific place within it

[frosty heron]

Try Ctrl shift f, type something relevant and hit the binoculars

[meager spade]

In this case I'm trying to find parameters or local variables containing it in a function library(not sure if ther are any but if there are I want to find them)

But I guess I would have to manually look through it then?

[frosty heron]

Ctrl shift f, type the variable name. Then hit the binocular

Or the param name

[slate fable]

how do you tell the face ID's apart? when I roll the dice it says it rolls 0 and when i look at the output log [which i just figured out was even a thing] and the ID is identical almost every roll.

[rich ferry]

Why do you have an integer-to-integer map where all pairs are identical...also you capitalized the A in map lol

Show the full code

[slate fable]

just a copy of another string above

[slate fable]

trying to map out the faces to the map and thought I would get lucky and they be one for one

[rich ferry]

why can't you just...?

[rich ferry]

I would check if that hit result actually exists or if it's null

I would also make sure it's hitting the actor you want

Did you get this system from somewhere or did you make it yourself

[slate fable]

it doesnt matter to me much what it hits, it calculates it whenever it stops moving. Its a d20 dice I got it from help above and almost everything about it works the way it needs to I'm trying to build the last piece to complete this system. and that is to map the faces

[rich ferry]

Alright I see what you're doing

[rich ferry]

Why would you not care what it hits, you want it to hit the die right?

[slate fable]

i care what the trace hits yea i want it to hit the die from wherever it stops and straight up a lil skew from hitting the numbers as the numbers are a different face ID. but I dont care what the dice hits to calculate like it could bounce off whatever. it'll be placed onto a table surface anyhow.

[rich ferry]

Ye I was talking about the trace

[slate fable]

thing is.. I cant figure out how to calibrate it to when it hits be the right number and im working to figure out how to map it onto the map using the above for reference.

[rich ferry]

Is the debug visibility turned on for the trace in that clip

[slate fable]

yea

[rich ferry]

Why can't we see it

[slate fable]

should be able to?

small red line. i can make it bigger

[rich ferry]

Ah I see it

[rich ferry]

can you print the "hit actor" from that hit result and make sure it's the die?

[slate fable]

uhhh

[rich ferry]

Just plug it straight into a print string

[frozen ledge]

have you ever figured this out?

[rich ferry]

I suspect that because you're projecting from the inside of the die (right?) that it's not actually hitting the die.

[slate fable]

it already prints a string after the append?

[frozen ledge]

two problems with radial slider for me

1. thickness scales with screen
2. the opacity doesn't listen to the hierarchy or parent

any help with either of these ? ^ anyone?

[slate fable]

in the video on the output log it shows what it touches

i think anyways

[rich ferry]

do this rq, just to be safe

[turbid pecan]

Can you not have a map that has more than one value type?

Like keys are "int" but values are a union of "name" and "int"

[slate fable]

I did it and it gave me this

didnt change the result after rolling it

[rich ferry]

Aight so it does look like it's hitting the die

[rich ferry]

I know, it wasn't supposed to

[rich ferry]

I think I'm out of ideas tbh, maybe do research into how the "face index" pin actually works, because sometimes stuff like that is not intuitive. I do have an idea for a different system though that would be simpler in the code, albeit harder to set up.

[slate fable]

this one has worked thus far im gonna keep trying to mess with it to try and figure it out

if you come up with something else im still all ears

[rich ferry]

My idea would be to find the face-up world rotation of every number (so like, if 9 is face up, what is the world rotation of the die), and make that vector the input to your map. You should be able to tweak how close it has to be to the example vector to yield a match, I know you can do that with equals nodes.

So instead of doing a line trace, you just grab its rotation, plug it into the map, and get the face.

I just realized though, you would have to ignore the irrelevant parts of the rotation (like if it's on a 9 but the die is rotated differently underneath), so maybe that isn't a good idea :P

[slate fable]

@gentle urchin is the expert on this thing straight up GOAT xD

[golden kite]

This is the tail end of my AnimBP (everything else is stock). It's designed to allow me to blend between an idle pose (montage) and an animation in a Level Sequence (for dialogue).

Problem is, when it's wired up like this, I have to temporarily unwire it in order to scrub through my animations in Sequencer.

Is there an easy way to disconnect the "green wire" while in Editor so I can work in the Sequencer without issue, and then "reconnect" it during playback?

Or is this whole approach messed up? (I would have preferred to avoid montages altogether and just find a way to dynamically blend one level sequence into another)

[gentle urchin]

Attempts is wromg

`> vs <

Wait nvm

Phome tricked me

Wait

Does your mesh have collision?

You trace is set to ignore self aswell

[ancient heath]

If I have the class reference, how do I get the object reference of that class?

[gentle urchin]

You dont

[ancient heath]

😦

[gentle urchin]

Its like your holding a page in a car catalogue

You know its type and spec and whatnot

But you aint getting an instance of it

Unless you SpawnActorFromClass

Which could be what you want to?

[undone bluff]

you can just get all actors of class to grab an array of all instances or get actor of class for just the first result

if you don't have a huge hierarchy starting with that class it's also relatively cheap to do, it's not a brute force search

[lunar sleet]

Please don’t recommend using get actor of class on multiple objects.

[undone bluff]

commonly used method to get a reference to a manager class of which there is only supposed to be one instance, naturally the moment there is more than one instance you are essentially getting a random one

[frosty heron]

Someone should just make a video on how to reference for beginners

Eg. Subscribing to manager on begin play

[gentle urchin]

^ 😅

[frosty heron]

Or expose on spawn for editor time placed actors

[gentle urchin]

You gotta get the manager somehow tho

[frosty heron]

Get actor of class 😄

Perfectly valid for something like singleton

[gentle urchin]

Works for singletons

He

I usually end up.letting one of the base classes be the manager

Through a component

[trim matrix]

that's the easiest thing ever

[gentle urchin]

The Find in the map

Returns 0 if nothing is found bh that key iirc

I was using the retuemed bool initially to check that we actually had the key in the map

Thats how i did the mapping in the first place

[slate fable]

Your referring to the first of the two blueprint screenshots? When you mention the bool right?

I just took a break and ate some food but I'm about to start trying to troubleshoot it again heh

[gentle urchin]

The bool is refering to the "Find" node in the Map

the Final "Map" looked like this

swappping out the traces for 45 degree rotations and 8 attempts

looks pretty clean still

just changed a tiny bit it now looks like this;

Offset swapped to 10, Attempts reduced to 8, and rotation changed to 45

collision wise i an auto convex run with default settings

ended up like this

setting collision with both Simple and Complex

we're tracing complex

but i guess physics need the simple ?

[quick field]

Would anyone have an idea why an AI set up to move like this would work in editor but not in the packaged Build?

[slate fable]

How do you keep the trace visible for all 8 attempts?

[slate fable]

changed the code to the updated version. you are seeing multiple traces on yours but mine only does it once

[slate fable]

where are you getting the numbers to plop in these spots? lol I'm missing something

if I roll more than one at a time it changes the number. Is that the ID I'm looking for???

[dawn gazelle]

You shouldn't cross execution paths with your wires/references.

There's no guarantee that value that the Add Movement Input is pulling from is valid.

[quick field]

Ah. Ok yeah I get ya. I'll see if that works

[quick field]

So that wasn't the issue. In the packaged build it's like the gate is opening and closing multiple times (not sure if that's what's actually happening since it's the build). The whole situation is on a timer that starts on beginplay,

[uncut elk]

nope , never did figure out the issue , i just used regular sliders instead =T

[dawn gazelle]

The input leading into the "Enter" on the gate is from Begin Play?

[quick field]

it's from a event firing from a set timer that's called on begin play.

Essentially a pseudo tick

[dawn gazelle]

Movement Input is supposed to be something that's on tick anyway. Perhaps just use a bool that you set true or false (which you can set true or false using your existing events that are opening and closing hte gate) and a branch off of tick? If you're not using tick to "save performance" and using this gate method instead, you're actually consuming more performance as timers run on tick anyway and have additional logic to check whether or not the timer should fire, and the gate has it's own built in branch anyway, so.... may as well use tick.

[twin perch]

got a math wizz question: lets say you have 2 vectors and something traveling between those two vectors, is their a node that makes sure that no matter how far those vectors are from eachother the item traveling between those two vectors will arrive at vector B at the same time ?

or an equation ?

[dawn gazelle]

interpto

[twin perch]

interpolation does that ?

[dawn gazelle]

Takes current value, target value, time since last frame and and interp time.

[twin perch]

o7 cheers

so interp to constant ?

[dawn gazelle]

Yeah I think there may be easing on the non-constant version

[twin perch]

cheers my dude!

[quick field]

Still doesn't really explain why it would work in editor but not in packaged build

[queen cave]

Hey all! Im really struggling with a widget switcher issue where my variable progress bars aren't updating. im sure that I am missing something. is anyone willing to hop in a chat and help me out? im pretty sure i have watched all of youtube at this point and just cant find the issue

[frosty heron]

Your progress bar not updating shouldn't have anything to do with widget switcher

Try not to copy paste tutorials either

Setting the progress bar is as simple as one node. Progress bar -> set percent

[queen cave]

I have been watching and them implementing from tutorials but when i ventured off onto my own if where it got wonky. lol

I did that and the actual functions are all working but for whatever reason, the widget that is supposed to be updating when called to the player ui menu, only hold strong with the default values and wont adjust.
I used the same technique with my HUD however and those update without an issue. its throwing my brain for a loop

[frosty heron]

Start a new project, create a widget with progress bar. Then set the percent with event or over time

[lunar sleet]

@dawn gazelle gracing us with his presence. I thought you only live in #multiplayer now 😛

[tawny patrol]

Hello! I'm looking for a soluton for my "survivor" like game, these red cubes represent the enemies and for now they only AI Move to player. However they block my character and when they surround me I'm unable to move.

Do You have any ideas how can I make a system that will allow my character to push them a little bit when I walk towards them so I'm able to escape from them 😄

[unborn raven]

No way to destroy enemies? Otherwise you could get them to logically move back if they facing the front of the player and the player is moving toward them. To stop players cheesing this mechanic, ensure it’s only a cone of the front of the player, and then you could also only run this functionality when there is so many enemies surrounding the player

[tawny patrol]

There is a way to destroy them, but sometimes there will be a situation when there is not enough damage output to clear them all.
Right now when they surround me, I'm stuck until death, however in a game like Vampire Survivors you still can make your way out of it 😄

[queen cave]

so i did the test and the submenu work flawlessly but when i house it in a widgetswitcher, its like an activestate of the subwidget isn't being called. is there something i should be using to call it

[soft flax]

I'm having an issue with setting up a modular character for this game. Its broken up into the Head, Arms, Legs, and Body and I used the main armature for the main mesh that all the body parts are under. When I test the game I get this weird vibration looking effect on the character?

This only happens when I set the main skeletal mesh that plays the animations to non-visible and works when the main skeleton is visible. On top of that the animation stops playing when the main skeletal mesh is non-visible as well

I've got the construction script set up the way the unreal documentation has it as well

is this a different issue from blueprints entirely perhaps? like materials?

I should also mention I'm using a custom skeleton and not the UE5 one

[undone bluff]

just slap them with an impulse in the opposite direction when they collide with the player

[undone bluff]

https://docs.unrealengine.com/5.3/en-US/API/Runtime/Engine/Components/USkinnedMeshComponent/VisibilityBasedAnimTickOption/

try changing this

[soft flax]

I assume its the BaseEngine.ini file but what do I exactly change it to?

I've never messed with the actual engine files so I have like 0 clue about it

[undone bluff]

it should be exposed as a parameter in the details panel

I'm not actually sure it is but it should

[undone bluff]

there is a project wide default but that's more akin to just flipping a setting than messing with engine files

[soft flax]

ok, I'll look around on the editor and see if I can find it

[undone bluff]

just click on the skeletal mesh component for the leader and look for it using the search bar in the details

[soft flax]

ohhhh

ok I see now

ah ok, that did seem to fix the problem

[undone bluff]

nice

[soft flax]

thanks for the help, saved me a headache lol

[gentle urchin]

Just bypassing the hit index check

If attempts < 8 -> retrace

[unborn raven]

Ah then definitely the second solution :), something that lets the player push through them like that 👌

[silk sail]

I am making a multiplayer game and I am trying to make it so when a player holds down a key a progress bar fills up. When that progress bar is full I want an event to be called on the server.

[frosty heron]

So which part r u stuck with

Input pressed-> progress bar = progress fill rate (per second) * delta time

Have a function to run a server rpc when bar is fully charged

@silk sail

[silk sail]

its kind of hard to explaini can I screen share and explain it?

[frosty heron]

no

also it's easy?

U want to hold F, then the bar fill up

then you want to run something when the bar is filled

[silk sail]

I have my bar fill up when I hold the key, and the event runs if I hold the key on the server but on the client the bar fills up and the event doesnt run

[frosty heron]

The bar filling has nothing to do with multiplayer anyway

it can just be done locally

then u run a server RPC

[silk sail]

i'm pretty sure thats what I did

[frosty heron]

check what you run then and why it doesn't work

can't debug without having the project in hand

@silk sail show some codes

i can take a quick look

[frosty heron]

shouldn't be using multicast

but regardless, have u confirm that they run the server RPC?

and is your chest replicated actor

do a print string to check

[silk sail]

It only runs when the server is the one that holds down the button, when the client runs the bar fills up but the server rpc is never called

[frosty heron]

hard to know without seeing the test result

check how its run on the client then

it shouldnt have anything to do with multiplayer

Input is local

1st you want to check if you actually calling the rpc or not, forget about the actual logic stuff in the mc rpc

it could very well be your macro blocking every1 but server and no one can tell what go on inside it

[silk sail]

the macro just checks the value of the open? variable

[frosty heron]

again, I can't tell what it does from here

it could also very well mean that the variable are not in sync between server and client

eg in client machine the variable is false while for server is true

help your self by debugging

[silk sail]

the server rpc call runs if I switch the replication mode to anything other than run on server. When the mode is run on server it only runs if the server is the one filling the progress bar

[frosty heron]

Run on Server (Server RPC) means that it will run on Server machine

but that shouldn't have anything to do with your proggress variable

check your fill function perhaps

if u doing any rpc there because you shouldnt

[frosty heron]

as far as the progress bar goes I don't see anything multiplayer related

Print something here

and show me a video

[gentle urchin]

Mc should not be mc

Shouød be server

Unless server is also client, server dont need no animation to play. Just updating the chest state

Clients react to chest state on rep and start animating

[frosty heron]

only thing that can be an mc is the Special effect like gold coins bursting from the chest

shouldn't be using MC for other purposes

chest open = state

chest close = state

[frosty heron]

You shouldn't have any logic here to Hide widget or to open/close chest either

Server job is only to set the variable of the chest to determine it's state

for client OnRepNotify -> If Open -> Hide widget -> Play animation, etc

well I suppose you can do the hide widget and play anim for server in the server rpc, but since you are using BP, rep notify calls for the server too so you will end up doing it twice

[gentle urchin]

^

Is this chest single user only?

[gentle urchin]

If not replicating its state is... messy?

I see no rpc

Or server print

Also not sure if you can call an rpc on a server owned actor from a widget?

[silk sail]

then where should I call it from?

[frosty heron]

do you have any error? is chest valid for clients?

[silk sail]

the chest is valid for clients

[frosty heron]

Ok I see the problem

@silk sail you can't run any RPC on actors you don't own

read ownership in pinned section on #multiplayer

if you want to run an rpc from a client machine, route it from your controller or character or actors that you own

[silk sail]

i somehow managed to get it working

thanks for the help

[frosty heron]

you would still get problem if you don't make it stateful tho. eg late joiners will see your chest closed since in his machine, the event never get called

[silk sail]

you mean replicate the state?

[frosty heron]

For chest it can be as simple as a bool

bOpen , true = chest is open, false = chest is closed

[silk sail]

i have a bool called open that I have set as rep notify

[frosty heron]

I think, open/close based on repnotify. For the item spawn, spawn on server.

[frosty heron]

And from your character when bar is 1.0 run a server rpc that get the chest and open chest

But I think u done that since u said it's working

If u make open chest a server rpc and call it straight, rpc will get dropped for client since they don't own the actor

[gentle urchin]

also keep in mind that only server is allowed to set (and replicate) a replicated variable

clients updating it will only be local

and will ofcourse be overrun when the server sets it again

Hello. Is there a way to get a return value from a blueprint interface? Like everyone tells me to use interfaces for things like inflicting damage. But here I am thinking why? Because my previous method was using a component and then checking if the actor you try to damage has said component. This way you can have function with a return value and everything "just works". So can someone enlighten my stupid ass as to why on Earth I would replace this with an interface if it can't even return a value?

Like, I don't get it, sorry.

To me interfaces currently look like less useful components

Now, if they can return a value, THEN we're talking.

When I damage, I need to know if the damage was done succesfully.

[lunar sleet]

you can pass variables through them. who is this everyone? Why not just use the built-in damage system

[untold fossil]

Videos I found online. Some dude who says interfaces changed everything for him. And programmers I worked with also told me to use interfaces.

But I really don't see their use.

I mean for fire and forget stuff I guess they're useful? But haven't encountered a single time I'd need that in the 7 years I've coded in Unreal, but okay.

[lunar sleet]

They’re generally useful when a cast is too heavy (doesn’t apply for 95% of people in this server)

[untold fossil]

What is the built in damage system btw?

Never heard of that

[lunar sleet]

Apply Damage node

[untold fossil]

Ok, interesting

[lunar sleet]

OnAnyDamageTaken

[untold fossil]

Hmm, but that would stillr equire binding and stuff

My component system still looks handier and easier tbh

[lunar sleet]

Then use it

people tend to find something that works for them and then preach it like it’s the only solution

Nothing wrong with either of these options

[untold fossil]

Yeah I think I will. Interfaces isn't gonna work I think. Just wanted to make sure that they can't return anything. Cuz if they could, that would change my mind.

[frosty heron]

Interface can return

[untold fossil]

How?

[frosty heron]

just add a return output?

don't use it as a way to dodge casting tho

[lunar sleet]

Use the function version of the interface

[frosty heron]

they are both made for different purpose

[untold fossil]

I've tried that, but I have no clue how to use it

[frosty heron]

just add output

[untold fossil]

Oh, wait

waaaiiit a sec

I think I know how

[lunar sleet]

That’s what I meant by passing vars/params mb

[untold fossil]

HOLY. You had to double click them.

https://tenor.com/view/the-universe-tim-and-eric-mind-blown-mind-blown-meme-mind-explosion-mind-explosion-meme-gif-18002878

Ok, now THIS is handy

@frosty heron Thx!

Ok, yeah this changes everything. This I can see being very useful.

I finally get it lol

[lunar sleet]

Just another way to pet the cat

[frosty heron]

Don't misuse it tho 😄

[untold fossil]

What I hadn't figured out which led to my confusion is that you can use them as normal functions by double clicking them.

[frosty heron]

you use interface when you want to communicate between different class that don't share the same base class

[untold fossil]

I tought you could only use them as events

[frosty heron]

you want to cast when communicating between a class that shared the same base class

[lunar sleet]

Aye, interfaces are tricky

[tame pecan]

cast is expensive!! /s

[untold fossil]

Yeah, no worries. I still don't see an aweful lot of scenarios where I'd use interfaces tbh. But for this particular damage scenario I have in mind it's exactly what I need.

[frosty heron]

interaction

[lunar sleet]

https://tenor.com/view/shark-tank-how-much-huh-come-again-excuse-me-gif-10734793

[untold fossil]

But for an interface you don't need to cast, no?

[tame pecan]

tree fiddy

[frosty heron]

damage is probably fine too, I am not qualified to judge

[untold fossil]

You just check if it's implemented in the actor and if yes, call it

[lunar sleet]

No, but you need a ref

Interfaces and cast are 2 diff ways to talk to other bps, like texting and WhatsApp if you will

[untold fossil]

this is how I use em atm

this bad?

[frosty heron]

No but you can probably skip the does implement interface part

[lunar sleet]

If it doesn’t implement it’ll do nothing

[untold fossil]

But wouldn't that generate errors if the actor doesn't implement it?

[frosty heron]

Don't think so

[lunar sleet]

No, not unless you’re trying to access stuff that doesn’t exist

[frosty heron]

if it did then put it back 😄

[lunar sleet]

If it’s just a function call for example, it’ll just fail silently

[untold fossil]

Yeah sure ok can see what it does

yeah true

ofc it also depends on the returns variables. A bool is fine. But a ref would give errors.

But not gonna return a ref, only a bool

so think we're good

[frosty heron]

when getting return value, it;s always good to check if it's valid

[untold fossil]

yeah true

I do that

[lunar sleet]

Still seems to me like easier to use this but 🤷‍♂️

It even returns the actual damage caused

[untold fossil]

hmmm

[frosty heron]

Laura say the in built damage system is ancient

it does it's job

[untold fossil]

Might look into it then

[frosty heron]

but for a complex proj, I dunnoe, prob just want to use Gas

[untold fossil]

oh

[lunar sleet]

Well yeah if you’re using GAS throw all of this out the window lol

[untold fossil]

that gives me anxiety xD

[frosty heron]

you want to see the scope of your proj

[untold fossil]

Anyway, dunno, I think interfaces and my vitals component can work really well.

[frosty heron]

and use the right tool

[lunar sleet]

Aye, many ways to do this, pick what is right for you

[untold fossil]

the scope of my project isn't too crazy

If I were making a game with a massive amount of damagables or enemies I'd prob delve a bit deeper. But for what I need in my current project this will be more than fine I think.

Aight, going back to my dungeon! Thanks and laters 😉

[gentle urchin]

built in dmg system

only returns damage if done in c++

[plucky locust]

Hello, can anyone help me understand how to create an interstitial ad?

[sudden swan]

Hmm question, How would i switch between these two materials every 4 seconds?

[dire frost]

i guess a flip flop with a delay. just make sure to loop around

or to be more tidy. have two events SetMat1 and SetMat2 on begin play, you'd the SetMat1, it will set the material and after a delay it will call SetMat2 which will do the same except it will will SetMat1 obviously

[sudden swan]

Ha flip flop. Never knew that node existed XD

Not sure how to loop it around so it starts again

[dire frost]

yep. tho it's best to avoid using it whenever you need to know the state of something. a door opening/closing is the best example, you dont want to use a flipflop there mainly because the start state could be different

[dire frost]

make a reroute node, and connect that to the beginning of the loop

[sudden swan]

Not sure im getting it.

I guess i need to set the boole no?

with a delay

[dire frost]

oh no you dont need to set it.

it will automatically flip and flop for you. just make sure to loop around

[dire frost]

or you know...implement this arguably better method

[dire frost]

you do not need to set the bool yourself, just make sure to loop around

[sudden swan]

AH lol man my brain aint brainin

i thought how do i get the loop back but i can just plugin multiple in the flip flop again

feels unnarutal going back in the chain

[gentle urchin]

Timer -> flipflop

[dire frost]

you'd be surprised then that apps just loops back their logic

[gentle urchin]

Looping

Far cleaner

[sudden swan]

and timer you mean timeline node?

[gentle urchin]

So:
Beginplay -> SetTimerByEvent(4.0s, looping)

Then custom event -> flipflop -> set material

[frosty heron]

Delay in tick is useless

Use timer, don't curse Ur self with those looping execs

[gentle urchin]

BUT

Seeing what this is

I would suggest making a material parameter instead 🙂

Of 2 materials

[sudden swan]

This works indeed

[gentle urchin]

Material parameter is king

Gives you nuce control

[sudden swan]

Yeah thopugh bout that aswell just lerp the texture

just wanted to learn some more BP

[gentle urchin]

Lerp and motion conteols etc etc

[sudden swan]

This is nice tho both methods work

thanks all!

really helpfull

Do i need the begin play tho?

[gentle urchin]

Something gotta trigger it

Could be a custom event triggered from elsewhere if you want

[undone sequoia]

guys any tips ? I have targeting lock system i can lock enemy and i ahve it locked but I have no idea how I can put widget on it how I can attach widget on it so I can know its locked please?

😄

thanks

[fair pecan]

Hello everyone!
I'm looking for some blueprinting guidance in regards to an unlockable Double Jump-ability I am having in my game, in correlation with Launch/Jump-pads.

As it is now, when the player overlaps with a LaunchPad they get launched into the air. Just like they are supposed to. However, when the player later in the game unlocks the Double Jump-ability, naturally it would be nice to be able to do that extra nudge/jump even after getting launched by a LaunchPad. This works ONCE as long as the player has not used the extra jump/Double Jump-ability before having been launched away into the air. If the player keeps on getting launched multiple times they will not be able to perform the extra jump. It is as if the launching of the player never counts as "landing" which I suppose "resets" or "refreshes" the ability to perform jumps again.

I have been looking at different ways to solve this. For example, if the player has unlocked the Double jump-ability and overlaps with the Launchpad, the overlap should also "reset" or "refresh" the jump count back to 2. But it doesn't.

I'll share some screenshots on the Blueprints of the Jump mechanic, Double Jump-unlocked-function, the Launchpads Launch-function and two videoclips to showcase the issue. If someone knows of an solution I would be very grateful!

Here is the JumpFunction in the FirstPersonCharacter-Blueprint.

This is how the "Unlocking" of the DoubleJump-function looks like.

And this is the Launchpads Launchfuntion.

Here is the Launchpad in action with the player not having obtained the Double Jump-ability.

And here is one where DoubleJump is available. Notice that on the multiple launches I am trying to perform a double jump but to no avail.

[cyan bone]

wHY is my meshy with these weird quads if its just 1 Plane ?

[dire frost]

this is just how the "selection material" works. it's a postprocess effect so it doesnt care about how the triangles actually are and instead just kinda makes a mask over the object

if you really wanna see the triangles of your meshes accurately the wireframe view is the only way to go

[cyan bone]

yup

just a plane

but does this mean the material selection mask applies some kind of extra triangles to it under the hood

[dire frost]

no again it's a post process effect. it doesnt see triangles, just some pixel data

[cyan bone]

got it. danke

[dire frost]

de rien

[gentle urchin]

there's something about the case if you're already falling iirc

[cyan bone]

Can we not use the GameMode to store static meshes and instanced static meshes?
It seems that they dont show up in the game

[gentle urchin]

this is in the CMC

so it counts as a jump, even if its not

@fair pecan

[cyan bone]

Made a little video to show the issue ^

[fair pecan]

Ah, convoluted...Would you happen to know how I'm suppose to solve it using blueprints?

[gentle urchin]

Add an extra jump during falling

I guess

[fair pecan]

Wouldn't that then end up become universal for everytime u fall u get an extra jump?

[gentle urchin]

True that

Whats supposed to happen if you fall and got the double jump ability?

I would think the same as with the launchpad?

You could add it only during launchpad use if you want.

Or reset existing count

[frigid summit]

hi guys i have one blueprint and 4 group ids for every enemy placed in a level how can i start the attack of next group id if the previous group id is destroyed

[fair pecan]

Well if u fall and have the double jump u are able to perform one jump in the air.

Yeah I looked into removing or adding jump count like this but it won't register. Mby I'm doing it wrong?

[gentle urchin]

Max count != CurrentCount

Max count during launch pad must be 3 for doublejump to work

You initially jump to the pad

1 .. then you exceed airtime(?) Which makes it 2

Ok this doesnt add up in my head but 😂

Im almost certain your issue is related to thah snippet

I guess theres a fine line between jumping and falling ?

Is there some jump air time ?

Id imagine cmc doesnt count you falling untill after such time

Not at the pc so cant check..

(Plus its a nightmare)

[fair pecan]

Haha, alright!
Yeah I'd assume "falling" is whenever the player isn't on ground though. I can't find anything called Jump Air Time in the Blueprints. I have a float variable that has Max Jump Hold TIme of 0,4 seconds. But this issue has been with me since before I added that one.

[gentle urchin]

To test my theory

You can add a print to event tick

And simply print the state of "isFalling"

If you're right it should be falling as soon as you leave ground

[fair pecan]

Kool! I'll check it out! Thanks for taking the moment! I'll prob get back here if I still have issues hehe...

[civic beacon]

We are Creating a project in unreal engine 5.3.2 and we were trying to detect hit on the Vehicle door.
But found weird behaviour in the engine collision events.
Do any one have idea about that ? is that a bug or we are missing something ?
https://docs.google.com/document/d/1PUG-XD0vYrI8sd7jHEd_WYB7Npznx0WdFEnL9MAf1OI/edit?usp=sharing
Thanks in advance.

[gentle urchin]

You can also chevk rhe "OnMovementMode Changed"

Theres a mode for falling

[fair pecan]

I was correct in this btw

Just tested it out and it prints Falling as soon as I leave the ground

[gentle urchin]

Interesting

So.. 1 jump instantly counts as 2 ?

Yet you can doublejump

So that doesnt make sense

Ohh

Jumpcurrent ==0

AND falling

I see.

Thats why you cant jump when walking off a ledge

[frigid summit]

hi squize can you solve my proplem

[gentle urchin]

Not really no

[frigid summit]

ok

[gentle urchin]

What you ask is a bit troublesome to just explain

[frigid summit]

i tried this method but its not working dont know why

[fair pecan]

Now u get bombarded with messages lol. But the player is able double jump when falling if the double jump-ability has been unlocked. This issue only arises when overlapping with the LaunchPads.

[gentle urchin]

Right, because max jump count is 2

0 + 1 is still < 2 so its allowed

[fair pecan]

Yes, so what am I missing in regards to the Launchpad?

[gentle urchin]

Am i misunderstanding the print btw ?

Seems like its constantly falling

Hm so you can even do doublenjump when walkingnoff a cliff

How does that even work

[fair pecan]

Oh no dont worry about that, the print just doesnt have the time to dissapear before the next batch of "falling" messages pops up

[gentle urchin]

Im brainfarting a lot today..

[fair pecan]

Haha, it happens to us all

[gentle urchin]

But yeah i wonder whats going on with the launchmpad

Print the jump count while walking on it?

[fair pecan]

Right, I'll do that

[gentle urchin]

Also set print duration to something low 😆 0.0 while on tick is ok

[versed sun]

or set the Key in the Print

[gentle urchin]

Is that new ?

Cant recall seeing key there 😅

Print Text.... hmmm

That does feel new

[fair pecan]

Ok this goes over my head atm anyway. When I jump on the LaunchPad without DoubleJump Unlocked, the Current Jump count becomes 1 everytime I launch away. But when I jump on it with the Double Jump unlocked it starts counting to 2, then keeps on saying 3.

Thats with no Double Jump unlocked

This is with Double Jump Unlocked

Ah no ok lol the LaunchPad counts every Launch as a jump. So if I do more than 2 (which is max after u unlock the double jump) I am not allowed to make another as long as I am launching around.

Wouldn't there be a pretty easy way to "reset" jump count on overlap with the Launchpad?

[gentle urchin]

ResetJumpState?

StopJumping i guess ?

Doesnt work if you're falling tho

[fair pecan]

Ah shoot I thought that was it

But no success

[gentle urchin]

How about

Just keep incrementing max jump count?

Whenever you land on a launch pad?

Reset it to single or double when you land on anything else

[fair pecan]

An increment float yes?

[gentle urchin]

Int, isnt it?

[fair pecan]

Ah yes silly me haha

[gentle urchin]

You might need to double the increment if thenplayer alrrsdy did a dounlejump, and you want to "reset" it completely

Doesnt feel like a smooth way of doing itn

[fair pecan]

Hehe, well I don't really know how to do it at all atm so I take my chances lol

[gentle urchin]

Do you do any c++?

[fair pecan]

No Im bad as heck on that stuff

haven't done any of that on this project thus far either

[gentle urchin]

Sonif you got presented a solution inc++ you wouldnt do it ?

Sounds like you've dipped your toe already 😅

[fair pecan]

Haha I guess if there was a solution that I could just copy/paste I would try it. But I would also b freaked out I'd break something haha

[gentle urchin]

Is it singleplayer?

[fair pecan]

Oh yes its singleplayer

[trim matrix]

Is there any difference between AddImpulse and LaunchCharacter, other than the option to override XY or Z velocity?

[gentle urchin]

Iirc currentjumpcount isnt exposed to bp

I suspect its there in c++ either directly or through some function

[fair pecan]

Well u can drag out a GetCurrentJumpCount from a As BP First Person Character and connect it to a print string, if that is what u r thinking about. So in that sense it is exposed yes?

[fair pecan]

I have never used AddImpulse so I wouldnt kno, u think that would change the behaviour of this conundrum?

[gentle urchin]

But you cant set it, right

[trim matrix]

No idea of your issue, I asked it as a separate question. Life is one big coincidence.

[fair pecan]

I guess u can?

[fair pecan]

lmao sorry haha

[gentle urchin]

thats just max

not current

[fair pecan]

Ah

I c wat u mean

Then u are correct, the current jump count isnt exposed by itself in the bp, I can just make it print the value through the method I mentioned before.

[gentle urchin]

in c++ we can modify it

so a c++ char base class

declearing a new function ResetJumpCount

which just sets current to 0

.h
UFUNCTION(BlueprintCallable)
    void ResetJumpCount();

.cpp
void ACharacterBase::ResetJumpCount()
{
    JumpCurrentCount = 0;
}

[fair pecan]

Is this in the FirstPersonCharacter BP? But in C++?

[gentle urchin]

you'd want to make a new c++ class

child of character

then reparent firstperson to this 🙂

[simple echo]

Hey y'all, I'm trying to spawn an actor BP when I left click, and assign it a specific property ( a local variable of the spawned BP)

For some reason, the vector keeps getting assingned to 0,0,0 (blue print string)

Can someone let me know if I am missing something critical?

[gentle urchin]

and just call this on launchpad

[fair pecan]

Alright! New things for me to look into, I thank u a bunch for going through so many options with me Squize!
I'll have to call it for today though, but I'll get back if I manage with this! 🙏 👏 🙌

[simple echo]

Squize is a champion

[gentle urchin]

Cant you expose it on spawn?

Beginplay probably fires before you set it

Hard to say what your prints tell you as they print the same thing, a vector

But their sequence would confirm/deny my first thought

[manic vessel]

If I draw a vector between the 2 green points and I want to get the black arrow vector buy using the characters forwards vector or yaw ( blue dot) how would I do that

[simple echo]

Yeah, expose on spawn was the trick. I didn't know about that 🙂

[spark steppe]

#game-math

[manic vessel]

I asked GPT , Think i have my answer

[arctic cloud]

Doesn't "Get Right Vector" work?

[manic vessel]

from the middle of a vector ?

[twin shale]

Does anyone know if there's a way to get this behavior in the editor through Blueprints? You select a class, then all of the Instance Properties from that class become editable. It changes depending on which class you have selected

[arctic cloud]

I'm not sure, but I think the forward vector of one of the green points is equal to the forward vector of the vector drawn between the 2 green points. Since you only need a direction, you can use one of the vector nodes (Get Forward, Right or Up Vectors).

[steady night]

Hey im using a Slot Grid

how can i get them to stack next to eachother ?

0,0 0,1 colum/row now

[arctic cloud]

Should go in #umg

[snow oasis]

Does anybody have any good resources (Preferably videos, I'll pay if I have to) for learning about Vector Timeline Tracks?

[arctic cloud]

I mean, you can try these:

Thanks

[gentle urchin]

Allignt top, Left

[steady night]

[gentle urchin]

Lies

The grid stretches

Expands horizontally and vertically

So the slots share whatever space there is

Now the slots seem to be fixed size, so spacing isnjust whateverd left, shard amongst them two

[idle vessel]

How do I fix this object that's attached to a spring arm that's still clipping in a wall?

[unborn raven]

Needs to be within your capsule component to avoid clipping

Any meshes attached to the capsule component loses blocking collision used for movement

[idle vessel]

It's working better now, thank you!

[spark steppe]

does it have a proper collision box? also disable auto weld/wield in the details panel of the component

[simple echo]

In my first person project, I'd like to freeze the camera rotation while the player is holding down the left mouse button.
Is there a Blueprint node I should know about?

[gentle urchin]

Not really

Orient to control direction ?

[lucid egret]

Search for matt asplands tut on how to limit camera view > make that blueprint connect to a keybind event. I believe that would work

[faint pasture]

Do you know how the camera is being rotated?

[simple echo]

just the basic camera movement from the starter first person controller

This is kind of what I'm looking for

[faint pasture]

Yeah, so start by understanding how it's rotating, then it'll be obvious how to make it not rotate when you want

[north lynx]

Hi!
I have a problem
When I use my own textures from Substance Sampler, UE5 don't scale them down according to my settings
Any ideas why is that?
Here's code for changing the Texture Quality

[glad ether]

Hey, I am making a system that I can hold and rotate certain items by holding "F" key, I manage to make holding the item part and rotating the item around worlds Z axis with the value from "Mouse X" but I can not figure out how I can make the item rotate using cameras X axis, I tried to rotate it on the pitch of the object but that's not giving the result I am trying to achive

related part of the current blueprint looks like this

[faint pasture]

That's because the pitch of the object is 100% independent of the camera's rotation

What do you want, to rotate it completely relative to the camera orientation?

[glad ether]

yes I want to rotate it on an angle relative to camera orientation though only for the x axis of the camera I still want to keep the the rotation that I do using the world Z like I do currently axis

[simple pulsar]

Hi, I’m learning blueprints and have one short question. Does anyone can tell me why longer Delay affects if my NPC will reach destination (as established in AIMoveTo nodes)? If Delay (placed right after AIMoveTo node) is below 3s NPC ‘says’: ah, I’m not going that long, I’ll stop in half way and go back. When Delay is 3s NPC goes politely where asked.

[gentle urchin]

Not dure what you mean by this ^

Oh, do you mean he doesnt go the full way?

Whats happening after the delay?

Show some code

Its probably set up wrong

On success

Is what you wanna use

Thats when i've reached my target location

Thats where you put the delay

Then new moveto

[undone bluff]

yea that's the a lil tricky part

but it's actually relatively easy

you just rotate around the camera's right vector

[glad ether]

true but I couldn't really find a way to convert the right vector to a rotation

I tried to use "make rot from x" but doesn't give the result I wanted to achieve

[glad ether]

let me apply this and then I'll let you know if I can make it work

[undone bluff]

I just tried it to make sure and it works perfectly

[glad ether]

I did like this

It works correctly on one when my player is aligned with the world x axis for some reason though

[undone bluff]

here's what I have that works correctly no matter the orientation. hold rotation is just the current rotation of the object

[glad ether]

Pretty much same with mine

[undone bluff]

I combine x and y rotation and then combine them with the current rotation

[glad ether]

Do you mind me to show you result by sharing my screen?

[undone bluff]

it probably doesn't matter

but you are combining the rotation with the x axis rotation first

and then combine in the y

[glad ether]

Let me swap it

[undone bluff]

worth testing

[glad ether]

Still the same

[undone bluff]

odd

what is the offset rotation doing?

oh

just to be clear

[glad ether]

when I start to hold the object it get's the rotation at that time so it doesn't snap to cameras rotation

[undone bluff]

when I set the target transform of the held object

I also combine the held rotation with the world rotation of the camera

so the object is already rotating with the camera when it rotates

[glad ether]

I also do a similar thing, I set the offset like this

then I use that offset and camera yaw to rotate with camera

[flat coral]

Is there any reasonably-efficient way to get all actors with a given Actor Component?

Actually it would have to be pretty fucking efficient, the way I'm planning to use it

[undone bluff]

nope afaik

only such relatively efficient thing you can do is get actors by class

everything else is by miles slower

[rugged lily]

Hello everyone! Need a little advice 🤔 Im using the VR Pawn and controlling various pawns in my world with it (i needed to keep them as pawns rather than actors for a few reasons). I'm using proxy player controllers to get around the possession issue, but I'm sure this isn't the proper way to do it. Does anyone have suggestions?

[glad ether]

Only way I can think of is make an object array to your game instance blueprint and on the each actors construct script that has that component add a fuınction that adds itself to that array and you'll have a constant list that keeps the list that has the info you need

[frigid summit]

can anyone plz help

[flat coral]

Yeah that's probably what I'm gonna go with. The other option is to do like a non-stored version using events somehow? But gut feel is that'll be like 5x more code and I slept like shit so screw that

Crying for help

[strong rover]

Got a question as well I was hoping to get some insight on.

I have a struct for something the player can manipulate (Not an individual object)
This item can have an identical item as a child. Recursively.

In this struct, containing all the necessary information to load, modify & save this item, I would also like to have an array that contains their children.
But UE5's Structure editor does not let me do this. It also does not let me make a container struct, which contains the array instead.

Does anyone know why this is, and if there's a safe and reliable workaround?

[glad ether]

you can make a function that calls the attack event on actor destroyed, (you can find the next group by getting the id of currently destroyed group id and add 1 to it)

[strong rover]

I recommend keeping a manager object for this if you don't have one already.

The manager stands between whatever system governs these units and keeps track of all the groups.
When a group is destroyed, have them call an event back to the manager to report their destruction.

The manager can then also have an array with all the groups. When a group finishes, it can also send a (different) call to allow the next group to go.

[faint pasture]

You need to do the linking outside of the struct, so to speak

basically value vs reference/pointer

[glad ether]

With the events it will be not as efficient as keeping the array when they are created (and removed if they are destroyed)

[slate fable]

So ive been trying to map this d20 for a hot minute and ive found that when I roll it, it always gets the Key = 0 which when i change the number on the right side. of the key 0 it gets whatever number i plug into that one. I've not figured out how to get the multiple traces yet if that's the issue. How do I go about finding the face ID's because they all revert to that 1 number which is zero??? EXample photo the # 0 rolls a # 14 everytime I roll the dice.

[flat coral]

To expand on what Adriel said, A struct can store a string or an int, and it's the same every time. But you close down Unreal and restart it, the reference point will be referencing a different memory address, even if it's the "same" object there.

[frigid summit]

the proplem is it give me this error when the actor is destroyed i call start attack Blueprint Runtime Error: "Accessed None trying to read property CallFunc_GetBlackboard_ReturnValue_1". Node: Set Value as Bool Graph: EventGraph Function: Execute Ubergraph Corpsebpfull 1 Blueprint: corpsebpfull1

[faint pasture]

Even that doesn't really get to the real problem. How many bytes is a struct which contains an instance of itself inside it?

It can't be a contains, it has to be an IndexOf or PointerTo

[frigid summit]

this is what im working with

[flat coral]

I mean, yeah, you're trying to attack something that doesn't exist right? You should have a check before the attack that makes sure the object is valid, OR write attack in such a way that it can attack just a location in space

[strong rover]

Well, the good news is that I've made a basic UUID system to manage these kinds of things between runs...
The bad news is, it doesn't make it easier to make my system recursive.

I suppose I could make multiple arrays of the layers. In the event of a recursive, it can point to the UUID-alike I made, which can be hosted in another map with the actual information. So child data becomes a little abstracted but available.

[faint pasture]

Easy, just have a UUID of the stored thing, not the stored thing itself

[frigid summit]

even with manager same error

[faint pasture]

Struct Thing
UUID MyID
UUID IDOfStoredThing

That's valid

[frigid summit]

the blackboard is not valid

[faint pasture]

You just can't go:
Struct Thing
UUID MyID
Thing StoredThing

[strong rover]

Yeah, I think that'd work. Not as easy as I would've hoped, but reliable is more important 😉
🙇 Thanks @faint pasture !
🙇 And thanks @flat coral !

[faint pasture]

I have some ideas for an inventory system that works a lot like that, how are you planning to handle multiple stored children?

[strong rover]

(Be right with @frigid summit , taking some notes)

[gentle urchin]

Your second branch isnt connectef to the bool om the "Find"

[rich ferry]

Is there any way to edit the drag of a projectile movement component? Or should I just decrease the mass to mimic the effect

[slate fable]

always that one tiny lil thing hahaha thank you @gentle urchin

[faint pasture]

Do they have drag?

[strong rover]

I'm making a system which is meant to allow the player to personalise a lot of things, as half the tool/game I'm building is about ownership and creativity.
I'm thinking that in this case, as children are rare, I will keep an array and a map.

The array is for the base layers, it is an array of this struct.
The map is for children, and children of children.

The Key will be their UUIDs from the system I built.
The Value will then be the children stored in this map.

That way, when I enter a "Has children" loop (Recursive) it will always reference the map and can ignore the base array of purely 'parents'.

[rich ferry]

Do they? lol. You would know better than me. I can't find a drag option using the search bar.

[faint pasture]

they might not

I don't think the PMC is great, just make your own, it's simple

Tick -> update velocity -> calculate next position -> trace -> move the thing

then you can put drag in your update velocity code

[slate fable]

Sad days connecting the bool didnt change anything 🤣

[strong rover]

I had something similar to this.

What I did was:

1. The object to be destroyed has an event: Event: DestroyObjectSafely
2. The event then called its parent Event: ChildCalledSelfdestruct
3. The selfdestruct would take care of the child's "Affairs", safely removing it from arrays, references, and cancelling its turn.
4. Once the affairs were dealt with, the parent was the one to delete the child, as the system was now ready to move on without its existence.

EDIT: In short, by having an event to delete any references and update systems, the destruction of the child would not interupt the cleanup operation before it was completed. No empty references should survive, and the manager was aware to push the system to the next turn/round.

[gentle urchin]

Hows the trace looking ?

Hitting the outside?

[rich ferry]

I'll probably just add drag separately and keep the PMC, I already have all this set up :P

[gentle urchin]

Its not

[slate fable]

nope it still registers as that key 0

[gentle urchin]

Where is the hit point

Its not there

I bet its below, inside

[slate fable]

adjust the length of the trace then?

[glad ether]

@undone bluff I think I found the source of my problem

[gentle urchin]

Verify its hit first

[rich ferry]

I had him print out the impacted actor yesterday, it looked to be the die

[gentle urchin]

Its the die alright,

Its just wrong side of the face

[flat coral]

I hate to say it but honestly you might be running up against the issue that the trace approach is kind of a crappy hack. I dunno if there's a better approach fundamentally other than just taking the world rotation of the die and doing a LOT of math

[rich ferry]

That was my idea

the math not the trace lol

[gentle urchin]

Its just the trace not hitting the outside

[slate fable]

🤔

[gentle urchin]

Its hitting inside for some reason

So, verify, Darryl

[lofty rapids]

i saw someone use a six sided die but they just added some blocks and took the highest z

[flat coral]

Wait actually here's a way to make the trace more resilient that FEELS like a wild amount of work but isn't: Take the trace end location, then iterate through the list of ALL faces and compare the distance between the center of the face, and the trace end location. Take the face CLOSEST to the trace end, rather than requiring the trace to actually hit it

[gentle urchin]

Could just add sockets aswell

And do highest z yes

[strong rover]

I'm assuming you want to read the value of the die?

Could you not attach a bunch of pivots equal to the number of surfaces (20) and check which one has the highest Z (Translated to World coords from local).
Not my forté, could be talking out of my bum.

[frigid summit]

ok ill try it

[strong rover]

Lel. Beat me to it.

[flat coral]

Highest Z is worth a fucking shot that's for sure

[gentle urchin]

Trace works tho!

I got the prooof

[rich ferry]

This feels pretty smart tbh

[slate fable]

it hits but idk what its hitting

[gentle urchin]

Zoom

In

Find out where it hits

Its gonna show a red dot at hit location

Then green after penetration

[slate fable]

no dot at all

[strong rover]

Gotta go feed the cats & have dinner.

@frigid summit lemme know how it went 💜
Kick butt, and thanks for the support 🙇

[slate fable]

no green either

[flat coral]

One thing though, for both my "closest to trace" and "highest Z" you've gotta make SURE that the face meshes have well-positioned origin points. If the origin of that mesh is set to like one of the corners or something, it'll all go tits up

[gentle urchin]

Sockeets

Can even extrapolate them

[strong rover]

If it didn't hit, maybe it's not set to hit any of the available physics channels?

[gentle urchin]

And be correct without a shred of doubt

[flat coral]

yeaaaaah sockets are more work but it'll 1000% work no doubts.

[lunar sleet]

Print the hit actor/component to know for sure and just for sanity check make sure you actually have draw debug enabled for duration if not persistent

[gentle urchin]

I can join vc / screenshare in about an hour

[frigid summit]

even chat gpt couldnt understand that💯 💯

[dire frost]

chatGPT is dumb anyway

[lunar sleet]

This is the 3rd time you’ve asked for help but lacked the reading comprehension or patience to understand what was being spoon fed to you in great detail and lashed out at people trying to help. Maybe it’s time for you to move on troll

[frigid summit]

wtf

[gentle urchin]

Did you find the hit?

You can draw debug sphere on hit location

To make it more apparent

[thin panther]

I'll never forget the time it told me to connect an execution pin to a pure node 🤣

[lunar sleet]

I rmbr trying to find all these easy to use functions that don’t actually exist

[dire frost]

it told me to check if the player grounded then call launch character...instead of just calling jump

[flat coral]

The only thing I use chatGPT for is naming variables lol

[lunar sleet]

Why?

[flat coral]

Because it's hard sometimes!

[gentle urchin]

Mynewvar

[lunar sleet]

I usually just go with something that makes sense like isBroken

[gentle urchin]

MynextnewVar

[lunar sleet]

Ig it depends on the context

[flat coral]

I'm a programmer not a writer! Well, I am actually also a writer in this case, but I'm bad at it!

[dire frost]

myVar1, myVar2, myVar3

[lunar sleet]

Oh is this for the cpp side?

[lofty rapids]

i keep using camelcase in my code lol

[frigid summit]

i red it like 9 times already and couldnt understand what he said : (

[gentle urchin]

Its one aspect you better get good at

[slate fable]

nope

[gentle urchin]

Naming varianles is important

[lunar sleet]

In bp we are blessed with being able to reuse var names without causing disasters 😅

[gentle urchin]

Verify that you actually get a hit.....

[dire frost]

this is a genuine advice from a fellow none-native english speaker. please learn english properly first then jump back to learning game dev

[thin panther]

I always tried to use chatgpt to name things but it was awfully generic.
i once asked it to give me punchy names for a space shooter and they were all things like "space wars" "celestial fight" "starship battle" "cosmic war"

[frigid summit]

ok

[flat coral]

Honestly my greatest sin for naming variables is not just sticking with the same answer. I'll name a component something, and not really like the name. But then when I make a list of those components I'll be like "oh wait how about THIS instead?" and then when I make a function to search that list it's like "actually how about THIS name, yeah! Love that!" but it makes it impossible to find anything lol

[dire frost]

i promise you it will help you out on the long run

[dire frost]

sounds like something ubisoft would publish now adays

[frigid summit]

or i can do the second thing instead of learning english and thats what i will do anyway 🙂

[lunar sleet]

Idk I name vars and components based on what they do, seems to work so far, but I may have not encountered your guys’ use case yet

[gentle urchin]

That sounds horrible, i must admit

[dire frost]

and it's working out great for you so far? learning a lot, are ya?

[frigid summit]

yea one year in

[lunar sleet]

🤫 maybe he means leaving us be lol

[dire frost]

oof

[lunar sleet]

F when you basically tell Duro and Luthage to F off cause you failed reading comp

[flat coral]

Look, you can do what you want, but end of the day if you keep asking questions where you don't have the tools to understand the answer, people are going to stop answering

[dire frost]

well all i can say is consider my advice at least

[slate fable]

goes thru the dice jus doesnt register a hit

[gentle urchin]

Where is the drawn debug sphere?

[dire frost]

yeah 1 year of "experience" and cant even understand what people are spoonfeeding your is rough

[gentle urchin]

In the mesh settings

Set its collision to be simple and complex

[frigid summit]

yea ok than i will stop asking here than if that happens

[lunar sleet]

Eh people exaggerate these “years of xp”

[dire frost]

i personally dont care. the advice was meant to help you. if you dont wanna take it that's on you

[faint pasture]

If PMC lets you add force or modify velocity then that's trivial

[frigid summit]

not rough as several guys here who has 8 years of exp looollll

[faint pasture]

I have almost 10 and I still don't know anything

[dire frost]

im genuinely surprised by that! i always underexaggerate my experience so people wouldnt blame me for being so dumb sometime haha

[faint pasture]

10 as hobbyist so maybe worth 2 as pro

[thin panther]

You can have all the experience in the world and Minecraft will still say

[thin panther]

Yeah you never truly stop learning

[slate fable]

did that

[dire frost]

sure...

[lunar sleet]

Can’t stop learning when the engine gets updated twice yearly with brand new stuff

[lofty rapids]

make sure the dice is set to block whatever channel your using for your line trace

[dire frost]

and the new stuff are broken! (im looking at you state trees)

[thin panther]

I mean even if you were still on 4.14 you'd probably still be finding out new things :D
Lol, wrong reply, mb

[lunar sleet]

Can’t wait till we all have to learn Mover 2.0 and experience whatever problems it has lol

[gentle urchin]

So whats missing here...

What trace type you got ? And channel?

[lunar sleet]

Screenshots

[gentle urchin]

And how is the dice actor setup

Yes

Lots of screenshots

[lunar sleet]

I only trust people as far as screenshots go lol

[dire frost]

mover 2.0 came just the right time after i practically rewrote CMC 🫠

[thin panther]

I fear that it will struggle from all the same perf issues as the cmc

[flat coral]

At some point you just gotta cut it off and say "this is the system my game is using", or you'll never ship anything

[gentle urchin]

• all the day 1 bugs

[dire frost]

the performance issues of CMC are all coming from multiplayer stuff as far as i can tell from the source code. mover 2.0 promises to make multiplayer experience even better so i wouldnt get too hyped up for any performance gains

[slate fable]

no worries at all gimme a sec to find all those xD

[dire frost]

yeah honestly that's what gonna do with CMC. mover 2.0 sounds cool but maybe for another project

[sand yacht]

hey there I'm trying to find some material on procedurally generating a landscape / terrain with a seed for every new save, kind of like how terraria does it, but then just using a mostly flat landscape with some very, very minor hills

I've tried looking on youtube but those videos don't explain exactly what I'd like

[gentle urchin]

Noise generator , some light c++ and a procedural mesh ? 😄

[dire frost]

the issue with landscape is it cant have "holes" or more accurately, a case where a vertices are above another. instead what's typically done is a mesh is placed where a cave would be, and the landscape is just generated below the mesh

[gentle urchin]

You can go voxel

[dire frost]

if you want a procedurally generated landscape then voxel is the way to go

[gentle urchin]

Theres even a free version

Supports 3d/4d generation doesnt it

[dire frost]

note sure about 4d but yeah 3d is possible

[gentle urchin]

You can see time warp before your eyes

[dire frost]

||that's 3D tho||

[gentle urchin]

If you know, you know

[slate fable]

where do I check for the channel? in the mesh settings?

[gentle urchin]

In the code for tracing

And collision settings for the mesh in the blueprint

Also show the hieriarchy

[slate fable]

code for tracing as in visual studio?

[gentle urchin]

No

Bp

In the dice bp

[dire frost]

what are they trying to do?

has this problem been on for like a day now? 😄

[gentle urchin]

Trace complex

Should be true

Ignore self should be false

[gentle urchin]

I got no mesh for complex

So remove that

And test

[slate fable]

everything works perfectly now

Thank you all for the help. I could cry xD

[gentle urchin]

😂

Faces mapped correctly?

Congrats!

Now optimize

Swap with sockets

And go for highest z

🤣🤣

[slate fable]

i'll probably have like a million other questions but yea.... first off. how do I use sockets? i jus now see thats an option on the mesh window

🤣

I feel like eventually I'll learn enough of this I wont be asking as much but fr fr 1000% thank you all for the help thus far

[lofty rapids]

i heard complex collision is expensive ?

[flat coral]

It's moreexpensive than simple, but that doesn't mean it's "expensive"
