blueprint

[heavy hemlock]

Maybe. That's somewhere to start. You will have many places to go after that.

I think so, yeah.

[trim matrix]

I made a few of my own so I'd assume so, they kinda sucked though

[faint pasture]

I've worked with Unreal for 9 years and I've never really messed with Character much, Might not have to ever mess with the CMC if it's all on Mover 2.0 by the time I do a character game.

[wintry sphinx]

anyone know what could be causing the zombie to not hit much? can give more screenshots if needed

[trim matrix]

any chance there is somewhere I could find someone else to do this stuff for me? I'm in game design not game development, this is starting to sound like it's not possible with my skillset to implement

[heavy hemlock]

Here's hoping!

[faint pasture]

Sure, how much money you got?

[heavy hemlock]

Yeah. Many dollars will solve lots of problems.

[faint pasture]

What's the criteria to do the attack?

and is it cancelable?

[trim matrix]

I have some money but idk how expensive code is

[faint pasture]

Getting a perfect movement system would run you anywhere from $10k to $1m I'd guess

depending on requirements and your definition of "good enough"

nobody is going to do any real work for free

[heavy hemlock]

Something weird is definitely happening. The 'PlayerIsInRange' boolean is on, but they're not doing the attack.

[trim matrix]

ideally I'd just have a macro I can apply at the end of a movement event that gets my velocity before landing, and applies it after

[heavy hemlock]

That's definitely doable, but I would expect a variety of edge cases from that.

[gray quarry]

in editor my character starts at 90 Y axis but in exe it starts at 0 0 0

[faint pasture]

Why you mix and matching your ai like that

attack should be a task

[heavy hemlock]

Well that should be an easy fix then. Just set the rotation in the OnBeginPlay event for your character!

So it's always 90Y.

[gray quarry]

already did

doesnt work

only works in standalone and in editor

[heavy hemlock]

Interesting, then in the code that updates the character rotation relative to the mouse - why not set it there?

[trim matrix]

I'm collaborating with my friend on this project, he is better at math but only knows c++

[wintry sphinx]

tbh was watching this tutorial and adjusting it to work with my project but dont know what im doing much either, but this was how they did it

[faint pasture]

If you don't know what you're doing, figure it out

don't just paint by numbers

[heavy hemlock]

Maybe he can help!

[faint pasture]

If he actually knows C++ then BP is trivial

it's basically C++ in disguise

[wintry sphinx]

i have been looking at this today and yesterday and am not seeing the problem

[heavy hemlock]

That blueprint is a task I think.

But it should be in the graph.

[austere ingot]

does anyone know why when i possess a new pawn (a vehicle) it inherits the roll even after trying to run set control rotation after possession? if the car is on a hill sideways for example, the camera is now rotated to the cars axis

[trim matrix]

I hope so, he is just kind of a giant baby though

[heavy hemlock]

Oh it is there!

Right at the end.

[heavy hemlock]

Do you know if it ever gets into the attack node?

[wintry sphinx]

yeah as in the video i can jump around a bit of it, and for some reason it will attack then so very occasionally it will

[heavy hemlock]

I assumed that you were doing a school project or something. I think probably the only way you're going to be able to make your game work is to build the game in iterations as you learn things. So right now... you have a character who can move, and walk, and look around - that's great! Leave it. You have 10 000 other jobs to do to make a game. Do some of those, then come back to the character and use your new knowledge to improve it, then do some more of those 10 000 tasks, and come back again, each time making it slightly better.

Do not get stuck on one thing.

If you stop because you get stuck - you're never going to finish it.

Does it work well enough? Move on to the next thing.

[heavy hemlock]

But have you confirmed that it's entering the node properly, and then exiting with the failure condition.

Or is it constantly re-entering the node incorrectly.

Or is it getting stopped?

If it's entering the node and failing - the problem is in the node.

If it's not entering the node properly, the problem is in the criteria.

[trim matrix]

kinda is for school kind of isn't, I'm meant to make a game on my own for my portfolio

[heavy hemlock]

You may want to dial down your ambition then.

[trim matrix]

(on my own as in without the school's instructions)

[heavy hemlock]

Make a game that is slightly harder than you think you can pull off.

Don't try to replicate a 100 million dollar game.

With you and your adult baby friend.

[trim matrix]

well a little more basic of a question then, I currently have a blink I made myself (think nurse from dbd)

I have a blink indicator that shows where you will blink to

the only way I could get it to work was to store the indicator under the map, then when holding the blink key it sets it's location to the end of the line trace

then after it sets back under the map

is that an acceptable way to do it?

I feel like it's kind of inefficient

[tulip anvil]

Does somebody know why this timer continues looping even when "is sprinting"= false ?

[wintry sphinx]

think ive fixed it thanks, if not found a temporary solution, need to look a bit at it

[heavy hemlock]

I think 'Looping' only reads during the initial Set Timer moment.

So you're setting it to loop indefinitely.

And then later when the Is Sprinting value changes, it doesn't matter.

[lofty rapids]

when does this code run ? the timer most likely won't update when you change the variable only when you create the timer will it be relevant

[heavy hemlock]

Also - this is almost certainly not the best way of handling a stamina system.

(yet another moment to use Tick)

[tulip anvil]

it only checks the boolean when it is triggered not every loop?

[heavy hemlock]

Yeah.

[tulip anvil]

i decrease the stamina based on time why would i want to do that every tick?

[heavy hemlock]

You want to decrease at a rate, right? A certain amount per second?

That's what Tick is for.

[trim matrix]

imagine not knowing you're supposed to use tick sometimes

[tulip anvil]

tick+deltatime would decrease it over time the same way a timer does though, only every single tick based on tick length rather then once every * amount of time.
i don't need to run it every single tick.

[trim matrix]

that's crazy

[lofty rapids]

check is sprinting in the decrease stamina use a branch put the logic there ?

[trim matrix]

so this is what I was talking about. is this an efficient way of doing it?

[tulip anvil]

yeah thats what i'm doing now 😄 i thought timers checked every loop whether the boolean was still true though, my b.

[heavy hemlock]

So you specifically want the subtractions to be chunky? Odd choice, but it's your game.

[tulip anvil]

the stamina is not visually exposed to the player, there is no point in making the number go up/down any smoother.

i use tick where i need to, and avoid it where i can.

[heavy hemlock]

But timers tick.

You are not saving evaluation time this way.

[tulip anvil]

only the timer, not the entire logic.

[heavy hemlock]

Right, but 'the entire logic' would be a single boolean value.

"Is sprinting?"

If that makes or breaks your game - you're in trouble.

[lofty rapids]

timers are really good for something to perform at a set amount, i feel like doing that on tick is less easy

[tulip anvil]

no it would be all the different multipliers and variables checking how much to decrease stamina, checking current and max stamina etc.

[lofty rapids]

you'll be doing all kinds of math to figure out a second

[heavy hemlock]

Why?

You want to reduce stamina by a certain amount while sprinting.

So on tick, you'd check 'Are we sprinting?' and if you are, then you subtract from the stamina.

That's it.

No complexity. Considerably less math than the transform update for a single background object.

[heavy hemlock]

The math to 'figure out a second' is a single multiplication. Tick comes in with a 'delta seconds' value, multiply your rate-per-second by that value and you have your modification you need to apply per frame.

[surreal peak]

I don't think either is really a problem tbh

Tick or Timer are both fine fwiw

Timer probably needs you to calc how much of the timer progressed already depending on the timer loop time, when you stop sprinting

I would probably do it on tick

[maiden tree]

I think what you’re doing works just fine depending on your needs. Just my two cents; If you wanted something cleaner, you could use “spawn actor of class” and just make sure it’s destroyed when it’s no longer in use. The class itself could follow wherever your hit location is while it’s spawned. I think that would prevent it clipping unexpectedly, if it ever happens with your setup

[trim matrix]

I did try doing that before and what happened was it spawned a ton of my indicators instead of just one, looking back at my code I figured out why

I need to run the spawn logic on started, and the move logic on triggered

[faint pasture]

How often do you want the stamina updated?

[tulip anvil]

currently about once every .25 seconds.

(timer set to 0.05 for testing purposes)

[faint pasture]

That's fine for a timer but I wouldn't go any faster than that. Once you start approaching "I want it to be smooth" then you're in tick territory

Using a timer with anything within an order of magnitude of tick hz is just tick with extra steps.

[tulip anvil]

mhm, i do for instance my health regen tick based, as the player would have those values visualized. for stamina i'm not too concerned if a player can sprint for an additional percentage of a second after it would of run out.

[faint pasture]

If you've already got health regen on tick just put the stamina there. It's probably possibly actually slower to have a second function handling stamina. Just put it all in one shot

[tulip anvil]

hmm, but then i would be checking if stamina should regen every single tick even when it is not relevant. IE if stamina has recently been used or while stamina is full.

i know in the grand scheme of things checking a few booleans every tick is negligible, but if it is not necessary, then why?

[heavy hemlock]

The overhead cost of allocating and deallocating a timer is probably more than that.

By a lot.

[tulip anvil]

i would likely still be running a timer for regaining stamina though as that would be on a several second cooldown. so the tick would run in addition to the timer, not in place of. which is a timer rather then a delay because i need to be able to reset the stamina regen cooldown from various different places.

[heavy hemlock]

👍

Sorry for being pushy! I have a thing with people trying to avoid using tick for optimization purposes.

Hi I'm trying to change camera from third person to a fixed one. I'm loading a new camera inside level BP, it works but I can't make the HUD move again, any help?

[stoic crow]

quite possibly a dumb question. I have an actor that has a few "sub" actors that register their information with them on BeginPlay. It seems like the interface calls all happen at once, and only one makes it through each time. Is that a thing, or am I misunderstanding what's going on here?

i.e

elevator floor registers itself with the elevator on beginPlay, which in turn registers the floor with the UI widget

actually nevermind i see what it is

the panel widget wasn't ready. delaying the floor registration by one tick solved the problem.

[gray ingot]

Is there a "good" way to make gps? I need to make in hand device, and when i press LMB, it shows certain place on my map.

whats the local to world node called

[lavish elm]

Hey there! I was curious to see if anyone had tried to achieve this effect using CMC: as players walk up a steep slope, a force down the slope is applied more and more and then eventually forces players to slide down the slope. Similar to this effect in valheim (ignore the Sprint functionality, that seems easy enough):

How can I put a box around live players in a players camera? Im making an advanced soldier class that can see boxes around players like ESP hacks in games.
It shouldnt see enemies through walls, only when they are visible

[vague swallow]

Hi! i'm working on a attack range for my character where after clicking on a target I'd like to constantly know if its in range as only when its in range it enables my attack button. (Ranged attacks) My questions is, is it better to use a sphere collision and change boolean "InRange" to true if its overlapping with the character collision of the target? or is it better to do a line trace and calculate a distance between my character and the target? (If its the latter I think i might have to use event tick to check if the clicked target is in range?) Its a multiplayer game. what would be the best approach to this?

[reef tinsel]

Is anyone else having problems with super slow SpawnActor ?

it literally locks up PIE

[tidal tendon]

Traces are more performance friendly and sphere collision can sometimes miss

[heavy hemlock]

If you have anything close to a reasonable number of possible targets, just loop through the targets and do a distance test.

It will be cheaper and more accurate than physics tests.

[vague swallow]

Thanks! 🙂

[heavy hemlock]

If your game is multiplayer, you probably want to do this on the server, and distribute 'can target' values to each player - otherwise people can make hacks to give themselves infinite range by messing with that function.

[stoic ledge]

this returns a character class that custom characters inherit from? the current possessed character?

[tidal tendon]

I dont know what its named but how can I make this?

[tidal tendon]

If you are unsure what something return, just print it to check

[stoic ledge]

i just glossed over the mouse over tooltip "Character Object Reference"

[heavy hemlock]

This is a non trivial effect to pull off, and it will require some effort on your part. Here are the broad strokes.

1. Attach a component or tag to all objects you want to flag with this effect.
2. At runtime, determine from a list of those objects whether these objects are visible.
3. Use the 'Project World to Screen' function to acquire the screen position of those objects. You can probably use their bounding volumes to get their extents, then convert each one of those extents into points on the screen.
4. Add a ui canvas overlay and generate a square widget per visual object positioned where the projected points say they should be.

[dawn gazelle]

Draw a box around the actor bounds.

[heavy hemlock]

I would rank this as pretty solidly in the middle of 'intermediate' in terms of development challenge.

[teal yoke]

Anyone know how to do widgets for dedicated servers. In my controller I have custom event, then I have a box I interact with calling the event. Not sure how to connect target though, when I use the controller is says reference not found.

[tidal tendon]

I tried to do something like this but

isnt look like working...

Also Im trying to make it multiplayer compatible so every player should see a box around that enemy

[stoic ledge]

im confused by ur premis, but i dont think controllers are replicated

[thin panther]

Get a grasp on singleplayer before jumping into multiplayer, especially dedicated servers

[tidal tendon]

I ended up creating a billboard material and put it on a cube

It shows its a cube If I jump, but working fine otherwise

[heavy hemlock]

Cool solution!

[teal yoke]

That's easier though as it doesn't matter as much where you put things. I was able to get it working with listen server but don't want to go further with that because of cheating. So dedicated servers is the way.

[thin panther]

No but the point of getting to know multiplayer is getting to know how to do it properly

You can still follow the proper way of using unreal's framework and figuring out referencing.

You're just hurting yourself by jumping into the hardest branch of multiplayer

Especially as it requires C++

And a source build of the engine

[tidal tendon]

the only problem it being affected by post proccess effects, annoying...

[heavy hemlock]

I imagine it will also be visible around corners.

[teal yoke]

Going to learn proper way doing dedicated servers as it's the best way overall. Trouble is it doesn't seem many know how to setup multi and there's not many tutorials.

[tidal tendon]

What you mean

[heavy hemlock]

If an enemy is just around the corner, you will probably see the square peek out before they're visible.

[tidal tendon]

oh yes

Would be amazing if I could find a proper tutorial about this

But looks like nobody shows how to do specific things like this

[thin panther]

Well I hope you've got the space and specs to compile a build from github source. :P

You're making things harder on yourself for nothing and setting yourself up for likely failure though. It's better to not only have released something first, but also be well versed in proper single player etiquette, and be quite familiar with C++ and Unreal's API for it.

Proceed with caution :P

[sick sky]

im getting crazy.

my character does a linetrace on tick, it looks for a specific Object Type (a custom i made).
the linetrace hits the boxs with this object type.

but if i create new boxs with the same object type, or even duplicate existing ones in existing actors, the linetrace doesnt hit
any ideas ?

[dusky cobalt]

Is there any node or function in unreal that could help me do something like that:
When holding mouse, draw circle, increase radius when you move mouse.
After releasing button, get actors under the circle?
I know there is Draw Rect and Select actors from rectangle, but is there something like that for circle?

Or I just do some math and create circle from rect? 😄

[stoic ledge]

you're probably looking for a specific instance

sounds like you want an interface for this anyway

[teal yoke]

Will save that thanks. Currently I'm using blueprints to prototype then will convert to C++. With what I was doing previously it didn't matter as much where I created widgets so now I'm not sure if the correct way is to create them in the actor, controller, or character. Do you know?

[stoic ledge]

@teal yoke Not expertly, but i seem to remember something about widgets knowing who creates them. I create them in my character though, then i can pass the information from my character into my menus, like an inventory / loadout.

[sick sky]

i dont think its a code related thing, because i dont see WHY it would hit some boxs and not others (with same settings)
but here

Can someone please explain this to me? One of 2 variables returns True, However the AND node prioritizes the False for some reason?

[stoic ledge]

both must be true for and to be true.

you might be looking for an 'Or' gate

[wise ravine]

or gate?

[wise ravine]

oh sick

It works perfectly now, thanks @tulip anvil and @stoic ledge . I don't completely understand the logic, but I'll try and re-read it another time 😅

[tulip anvil]

basically AND will only output True, if BOTH inputs are True

OR will result True if ANY input is True

[wise ravine]

And OR is the opposite?

[trim matrix]

what happens if I don't check this, should I check it ? I don't see any change

[heavy hemlock]

I'd check. If its false, you'll just have nonsense in the two vectors.

[valid solstice]

If I wanted to make a directional dodge and like lock my characters rotation only when Im targeting how would I do that?

[stoic ledge]

'NAnd' is the opposite of 'and'

[trim matrix]

mhm I see

[wise ravine]

Does 'NAnd' function like 'AND' but with instead of true outputs, with false outputs?

[tulip anvil]

NOR is the opposite of AND it results True if all inputs are False

[trim matrix]

not is just like the opposite, and is both, or is either

[thin panther]

XOR is a good one to know, it's like an or (hence why it's called exclusive or) but it's only true if 1 is true, 1 is false

[trim matrix]

is it just | | in c++?

[thin panther]

as you can see, following this logic, you can have XNOR which is only true if both are true or both are false

[thin panther]

no, that's OR

[trim matrix]

these are just weird names, and / or -> Booleans are easy to understand

[tulip anvil]

😅 gotta love logic gates xD now imagine being an electrician and getting it wrong means you get electrocuted 😛

[thin panther]

xor is (A && !B) || (!A && B)

[rotund barn]

things are broken once again. i cant end this logic when i use a delay, any idea why? if i dont use a delay, it doesnt have time to do what i need it to do (kill all AI in a radius), but it does work and kill some before it shuts off as i change a bool to false at the end, if i use a delay before it turns the bool to false, it doesnt turn it to false ever and will keep killing AI infinitely

[tulip anvil]

they make perfect sense once you understand their defenitions.

[trim matrix]

and why is that important?

XOR doesn't exist in c++

[thin panther]

Yes it does, I just showed you how to make it lol

[stoic ledge]

XOR does it?

[trim matrix]

to make it

[tulip anvil]

because often you might want to check 2 bools and make sure only 1 and never both are true.

[thin panther]

yes, an XOR is an assembly of other logic gates.

[trim matrix]

you just do booleans stuff randomly, not using XOR particulary

[thin panther]

that is possibly the most false thing you could have said

XOR's are one of the fundamental logic gates and used everywhere

[trim matrix]

byu randomly, I meant your logic

[thin panther]

no?

that's quite clearly not random

given it's a clear definition with clear outputs and well defined meaning for decades

[trim matrix]

do what you do with your booleans, dont do XOR.

[thin panther]

I'm not sure if you just don't understand it, but don't advise other people to throw fundamental boolean logic out the window because of that

XOR is used everywhere in computing

[trim matrix]

'fundamental boolean logic'
ew

[tulip anvil]

these logic gates are what the entire digital and electrical world relies on, almost every computer, processor, light switch, electrical grid node you name it... in the entire world... is just a combination of these logic gates. (plus a few extra things)

[trim matrix]

I can ensure you that I can do even more than these simple gates thingy

just be able to understand boolean

[thin panther]

hell your computer right now is using xors everywhere to reset a register ready for an input

[rotund barn]

your processor is literally 99% made out of those logic gates

[thin panther]

they have the nifty ability that anything xor itself is 0

01010010 xor 01010010 = 00000000

[tulip anvil]

the amount of boolean logic gates within a single computer is litterally mind blowing xD

[thin panther]

truly is

[wise ravine]

thats cool

[thin panther]

I remember building part of a 6502 on bread boards with just logic gates, and it was insanely large after only finishing the ALU and the registers

[trim matrix]

this is bitsets

[thin panther]

it was huge

[rotund barn]

yeah, an they are just a few atoms in width, insane

[thin panther]

no, that's boolean logic

what do you think a boolean is, it's a 1 or a 0

[trim matrix]

I know

wut

[tulip anvil]

a boolean, = 1 bit

[trim matrix]

false

it depends

and will surely not be 1

[thin panther]

well, sure most compilers pad them, but the fact remains is it's 2 states, which is by definition a bit

this is why you see uint8 bMybool : 1; Because it's a single bit, and you use it like a boolean

[wise ravine]

not to interrupt this conversation, but anyone know why my BPI isn't being called in my receiving BP after being activated in my character sender BP?

It's ECC_GameTraceChannel1, ECC_GameTraceChannel2, etc

for user defined.

[wise ravine]

would this work?

[trim matrix]

by user defined, you mean the 18?

[thin panther]

Most people end up typedef'ing them because the naming is ass

For the engine ones, it's your standard, ECC_WorldDynamic, etc,

[trim matrix]

how could I use the normal one

--
Visibility

[thin panther]

No. An interface isn't a magic function. You still need to call it on an instance of that object. your player is never a button, so calling it on yourself is never going to be able to call it on a button

[trim matrix]

type def is wrong tho
Alias are better

[thin panther]

typedef isn't wrong, it's just the older version

People will fight that camp until the cows come home, but it doesn't really matter tbh

using is often less typing

and that's pretty much it

[trim matrix]

and bettter

[wise ravine]

Right. I forget my blueprint communication training :/. I should rewatch the video. Anyway that should help, appreciate it

[faint violet]

I'm calling Ai MoveTo every tick, is this bad for performance?

[tidal tendon]

Why you are doing this?

Are you want AI to always follow the player without even seeing it

[stoic ledge]

no? shouldnt u call the function for the ai to move only once?

[faint violet]

hmm idk. cuz if it doesnt matter imma be lazy and keep it every tick

[tidal tendon]

What you want

Whats your purpose I mean

[faint violet]

imma have it doing checks, so imma need to start it again after I cancel it

idk if ai move to triggers once or not

[tidal tendon]

If you want to check it regularly in small intervals and from everywhere

You can decrease sensing interval

and increase the sensing range/angle

Putting things in event tick should be last thing to do

[faint violet]

no, im just wondering if its bad for performance. if it is, I'll set it up to a do once

cuz maybe it does a check

[tidal tendon]

I dont know what exactly you want, but If its possible to not use event tick, dont use event tick

Putting things in event tick is not the best thing you can do for performance

[faint violet]

I cant open it in vs, so I cant see if there is an "already running" check or something

whatever

[rotund barn]

is there a way to constantly check things from begin play, but a bit less often than event tick so its more performant?

[faint violet]

I think delay is better, but ive heard Timer By Event is just as bad, or worse than event tick. but if ur checking branches, its prob not that bad [dont hold me to it]

[rotund barn]

oh okay, and yeah im using a delay on my ai move to, but i was more thinking about other things.

[faint violet]

I was thinking about using an in game clock, but nevermind.

[faint violet]

wait I forgor, I need event tick for location anyways. does anyone know if its more expensive than adding velocity tho?

[dawn gazelle]

Rather than check things constantly, call functions or use dispatchers to signal that the thing happened.

[rotund barn]

but im usually checking if something happened by checking a variable with a branch from event tick

[stoic ledge]

isnt that crazy? or does a tick not happen very quickly

[dawn gazelle]

And that's the wrong way to go about it.
You can use the variable to indicate that something may have already happened in the past to know that it happened, but you can still signal when something started.

[rotund barn]

oh but wait, i think i could maybe check if the variable reaches threshold where ever it was changed or incremented

could that work?

and actually to make my previous statement even worse, i have like 20 custom events from event tick, all of which are checking stuff, and when conditions are met, firing other stuff as well

[dawn gazelle]

When you adjust the variable that is when you'd do that check, and if your check is good, signal that something needs to happen.

[rotund barn]

okay, yeah that makes sense. im still very new to this so im doing alot of stuff quite wrong. my main goal is that things work, but also slowly learning better ways to achieve things

just the other day my dumbass incremented a variable 100 times in a row with a delay between each node.... just for a reload timer bar thingy...

i did use alot of timers but didnt occur to me at 5am that day

[rain wraith]

If an actor is destroyed upon closing the game and respawned on load, do the respawned actors not remember what Blueprint Interfaces they had implemented? I'm using a blueprint interface to communicate a changing integer between two BP classes and it works fine except for when the game is closed and reloaded, then it no longer outputs the exec or integer

[stoic ledge]

its forgetting refrences to those outputs i think

[rotund barn]

i think you need to save and load the variables before and after closing the game

[rain wraith]

The integer I'm using is basically a timer though so that shouldnt be the issue since the timer is reinitiated upon GameInit

[dawn gazelle]

I believe this can sometimes happen if the interface is part of a plugin and gets loaded after your blueprints are loaded.

[rain wraith]

Not using any plugins with these BPs

[zealous moth]

@rain wraith what do you mean by closing the game and reload?

[sinful hinge]

If I put a loop on the Get, will the branch be true if all of the array is activated?

[rain wraith]

If the game is closed and reopened; in this case, playing the level in the editor, stopping, then playing again

[zealous moth]

I would try it in a packaged shipping build

sometimes in editor stuff gets wonky

[rain wraith]

It doesnt work there either

Already tried

[zealous moth]

put a print string on tick and check if it implements interface

I'd be curious of the result

[heavy hemlock]

No, sorry. It doesn't work that way.

The way to do what you want is to use a 'loop with break'. You loop through the pillars, and if any of them aren't activated, you pipe that into the 'break' statement which will stop the loop.

If the loop completes normally, then you activate the portal.

[sinful hinge]

Something like that ?

[heavy hemlock]

Close!

But rather than going from 'True' on the branch to the portal, go from 'completed' on the loop.

[sinful hinge]

completed instead of loop body right ?

[heavy hemlock]

The 'Completed' pin shouldn't fire until the whole loop is passed.

[sinful hinge]

yeah x)

oh, straight from completed to the portal ?

and only false on the branch ?

[heavy hemlock]

Yep!

[heavy hemlock]

Yep!

[sinful hinge]

got it, it loops from the array, if a false is detected, the loop breaks, if none is detetected, it means the loop is complete then I can enable !

[heavy hemlock]

Yus!

[sinful hinge]

Thanks 😄

[heavy hemlock]

👍

[rain wraith]

I originally did these by testing a boolean for true/false. At first I read this and was like I've already done that. But I went ahead and did it anyway and boom your approach made it so much easier to diagnose.

The integer from the BPI is used to control four different component transforms using array data. I only implemented saving/loading for the first transform component just to test before doing them all. Apparently even though there were no errors, this made the code not work since the 3 remaining component transforms were receiving NULL array data. Unplugged the the three set world transforms and everything is working. Now I can add the save/load for the other 3 transforms.

THANK YOU! <33333

[zealous moth]

oh np

i will take the credit

🙂

[rain wraith]

One other question: for the "Get Bone Transform" node, is there any way to get the transforms of all the bones in a skeletal mesh? Or do I have to gruesomely set up duplicated of "Get Bone Transform" for every bone in the skeletal mesh

[heavy hemlock]

There are... not a lot of scenarios where that would be necessary. What are you trying to do?

[rain wraith]

For VR Hands, I want to get all of the rotations of the fingers in the skeltal mesh, for both hands

[heavy hemlock]

OK, but for what?

What are you doing with it?

[rain wraith]

The rotation data will get saved into an array, then the array data is used to playback the bone transforms - sort of like a recording but in 3D space

[heavy hemlock]

For what though? Like - you're describing a method, but not an intent. Why make this recording?

[rain wraith]

Because it's for my simulation, for a uni class

I don't see the relevancy of the intent for this

[heavy hemlock]

Well, many things that someone might believe they need to read all the bone information per frame probably don't. I've seen people do that to attach particle emitters for effects.

People do weird shit!

If you need to record it for playback, you could probably use the sequence recorder, but the results of that are not easily accessible live - it's to create a sequence to be played back later.

So, if you needed to record the data for a cinematic or playback - again, there are tools for that, and the approach would be different.

The why you are doing a thing is always essential to include.

[rain wraith]

Whoops missend, one sec

I suppose. The intent here is a simulation which can, at runtime, record the live movement of a player's hands and then, at runtime on their VR device, replay all of the recorded gestures of the VR hands through a duplicated pawn that is spawned in.

And have the hand data be able to be saved/loaded

[heavy hemlock]

Hmm - a non trivial challenge that. The sequence classes in unreal that normally serve to store and retrieve animation data are not easily accessible even in c++. Getting access to them to write curve data is a bit of a headache.

And they're very inaccessible to blueprint, especially for writing data, so you'll have to record your data to arrays. The other problem is that your data will not be of a consistent framerate, as your game's framerate is dynamic - so you'll have to record the timestamps with each key.

[rain wraith]

Already have the custom timestamps set up 😉

[heavy hemlock]

Then you'll have trouble with playback. Because you can't easily record actual animation or curve data, the playback is going to need to be lerped between keys - so you'll have to build your own animation player.

[rain wraith]

I've already made the recording and replay system for the whole body of the VR simulation - I just want to now added the skeletal mesh transforms of the hands for added realism

[heavy hemlock]

All right, good luck.

[rain wraith]

I suppose something like this might work

Is there a way to get the number of bones from a component?

[heavy hemlock]

Note that the values you get from "Get Bone Transform" are always from the previous frame if acquired from the blueprint VM.

[dense badger]

Heya all, is there a way to get all the gameplay tags at a specific level in the hierarchy? Like if I have Items.Names[10 names in this category] would return a tag containter with just those 10 tags?

I feel like this is a tag query thing, but the pattern is escaping me...

[trim matrix]

Would a delay in a BP for loop would work as expected and wait the delay between each iteration?

[faint violet]

How do I cancel or succeed an Ai MoveTo? Acceptance Radius was working an hour ago, but I changed something and now its not.

[dawn gazelle]

If the false condition is never hit, then the value of Acceptance Radius variable will be whatever the default value is.

oh wait ya, but its just locking up the world position. ok nvm I found it, Stop Logic and Stop Movement from Brain Component of AIController

[onyx berry]

Hi everyone, I was hoping I could get some help. I've created two interface bp for a male and female character customizer. I feel the event OnWidgetConstructed is keeping everything in sync. Any idea what adjustments I need to make to split the interfaces? Thanks

[heavy hemlock]

When you say 'interface', do you mean a Interface Class, like one of these:

https://docs.unrealengine.com/4.26/en-US/ProgrammingAndScripting/Blueprints/UserGuide/Types/Interface/

Or do you mean a widget / ui?

Of a particular type, or just any component? And how many of them are in the scene?

Weird choice. They're not actors - they're components?

[trim matrix]

anyone know about this thing?

[onyx berry]

My apologies, I meant widget/ui

[worthy jasper]

You could test and find out. Should be pretty quick

[heavy hemlock]

Testing is always best, but I don't think so, no.

[dawn gazelle]

No, it wouldn't.

You could create your own looping macro that can accomodate a delay though.

[heavy hemlock]

All right, cool. I was very confused. I'm still a little confused. What do you mean by 'split the interfaces' and why is 'OnWidgetConstructed' keeping things in sync? Why do you want things to be 'in sync'?

Or you could use a timer!

(this is a place to use a timer)

[trim matrix]

mhm

maybe coroutines would work

[worthy jasper]

That doesn’t have anything to do with a delay in a loop

And depending what you did would probably be the opposite of what you want XD

[trim matrix]

what message are you responding to lol

[heavy hemlock]

Are those all in the same blueprint?

[worthy jasper]

Your co routines comment

[trim matrix]

there's no node LMAO

[dawn gazelle]

Would look like this.

[trim matrix]

coroutines are exactly what I want, just trying to find other ways to do it too

[worthy jasper]

Uh huh. If you say so you could also do the example someone kindly presented

[trim matrix]

maccros...

[onyx berry]

I actually don't want each widget to be in sync. Here's a video showcasing my issue. The event OnWidgetConstructed is the same in both widget bp so I thought the issue may be coming from there

[heavy hemlock]

OK, well... is your character always going to be in the middle?

[dawn gazelle]

The standard blueprint loops in unreal are macros

[trim matrix]

aren't they? they do stuff whenever yo uwant and comeback whenever you want

[worthy jasper]

You seem to know already but no

[trim matrix]

yea I know, I just don't like them cuz it always seems overcomplicated

[heavy hemlock]

I don't understand the issue. You're showing the different characters. Stuff seems to be working fine?

All right, well - if you want to get the distance between two objects (components or otherwise) you can subtract their world positions from each other and get the 'length' of the resulting vector.

[trim matrix]

Is it just me or you should load Async, because there's a lag

[heavy hemlock]

Do that with your six arrows, and choose the one with the shortest length.

[trim matrix]

did you create it yourself?

[dawn gazelle]

Yeah I just copied the existing ForEach macro and threw in the delay where it woudl need to go 😛

[onyx berry]

Did you notice how I selected female and then went back and selected male but the female mesh is still selected? That's the issue I'm having

[heavy hemlock]

I didn't, I did notice that there is a button you press to switch. So that's working, right?

[trim matrix]

did you make your entire game, or is it a model already made?

[heavy hemlock]

The problem is that when you use one of the main buttons, it doesn't switch.

There is a 'distance' node, but I think it's for actors.

You could look at that though.

[onyx berry]

No, it's a model already made

[heavy hemlock]

Loops!

[onyx berry]

Yes, but I'm trying to make it so that when you select male, it's default male mesh and vice versa, no need to switch

[heavy hemlock]

OK, so debug routine:

1. Confirm that the female widget is actually in the main ui, and you don't have two of the male ones.
2. Confirm that the female widget is actually designed to show the female character, and doesn't accidentally have the male characters meshes in there.
3. Put a break point on the part where the main characters mesh is selected. Step through to see the values as it's assembled.

[trim matrix]

And there's a bug in it? ew

[onyx berry]

Thanks for all your help! I'll give these a try

[mortal nacelle]

How is one supposed to debug blueprint code for a packaged server running outside the editor?

I have a bug which only seems to happen on packaged server builds, not in PIE multiplayer mode.

[onyx berry]

It's not necessarily a bug, I think it has more to do with how the original bp is constructed

[trim matrix]

how much was the pack? but yea sometimes you might want to change things up

[trim matrix]

Hey guys, Is there any way to convert enum to display_name?
I need it 'cause I found the intersection between classname and enum name so if it possible, I don't have to use switch anymore

So My questions are below

1. can I get class with name? (even using C++ that's okay)
2. can I get enum display name?

[sinful hinge]

I'm trying to trigger the function in BP_Portal from BP_SocketMaster by using an interface, but I don't know what to use as a target, and I could use some help...

[cloud spoke]

how so?

coroutines are functions that can be paused and resumed, if I had

TCoroutine<> MyDelayedLoopFunc(float delayBetweenLoops)
{
  for(int i = 0; i < 100; ++i)
  {
    SomeLogic();
    co_await Seconds(delayBetweenLoops);
  }
}

Then this would do a loop, wait x seconds, do another loop, wait x seconds and so on until I have done 100 loops.

I'd love for you to go in detail though of what your understanding of coroutines are

[twin jacinth]

It will need to be a reference to whatever instance of BP_Portal you want it to run on

[pallid gorge]

Does anyone know if there's a switch node that can compare object references?

[lunar sleet]

No

[pallid gorge]

RIP

[lunar sleet]

You can use nested casts

But if you have a lot use something agnostic

[pallid gorge]

Yeah I'm trying to get something modular

I want to be able to intake an actor to define which array to assign some data to

[lunar sleet]

Actor components can give you modularity

[pallid gorge]

Yeah I'm already doing actor components

[lunar sleet]

In before Authaer hehe !

[pallid gorge]

I just meant for the actual flowthrough of the code

Casts are too predefined for what I wanted

[maiden wadi]

You can get these things. but generally you should not unless it's explicitly for debugging purposes. Enums should just be a named integer to make it easier on the developer to understand the use of each number and that is as far as the name should go. It's metadata not meant for any end use.

[lunar sleet]

Well you don’t need a cast if you’re using an actor component @pallid gorge

[pallid gorge]

Well like I said it's more about defining where it goes once it's in the component

I need it to build an array for each unique entry and then be able to switch back and forth for which one it puts any new info related to that entry in

I can piece it all together the long way but I was hoping a more sucinct switch option would exist

[maiden wadi]

The same thing you'd use for the target as if you were casting. If you're not familiar with pointers/references and how to use them to call functions on things I would start with going through this. https://www.youtube.com/watch?v=EM_HYqQdToE

[compact hornet]

How do I get the normal rotation of a surface hit by a line trace? I'm scratching my head here. I have a line trace a bit in front of my camera pointing straight down. When I approach an object I want to make sure the surface I hit it is close to horizontal before doing the rest of my code, but I can't dont really understand how to get that information from either the normal or inpact normal from the line trace.

[maiden wadi]

Perfectly horizontal will dotproduct with UpVector or 0,0,1 with an output of 1. As they're the same facing. So you dotproduct your line trace hit result with up vector and pick a number you want as the allowance like 0.95 or so. The closer they are the closer to one. The closer to perpendicular like a cliff wall it'll be closer to zero. And if you line traced a roof it would be closer to -1

[trim matrix]

Hmm I figured it out simply way I use 'map' key: enum name, value: Class reference can I make in this way?

[maiden wadi]

Why not just use the enum as the key instead of it's name?

[compact hornet]

hmm... i'm probably doing something wrong because I get a dot product of 1 even if the surface is vertical

[trim matrix]

wdym it's name? enum's display name?

[cyan mortar]

Good afternoon, in the first function I created a local variable in BluePrint how can I set it in another function?

[maiden wadi]

You said that. key: enum name, value: Class reference

[maiden wadi]

This looks fine. You should definitely be seeing like 0 here if you line traced a flat wall.

[trim matrix]

Yeah, I do this to get class reference by name (string) but is there other way?

[compact hornet]

ok i think my problem is that when i walk to close the line trace starts inside the wall and some funky stuff happens. if i add a line trace before that prevents the it if it's not free it seems to solve it for now. don't know if it's the smoothest way to do it though

[maiden wadi]

It's fine if it gets you the results you want. 😄

[trim matrix]

Yeah definitely that's true haha

[maiden wadi]

About class names. There's a way to get a class via names.. Aliasing might work better though.

[trim matrix]

Oh How can I do that? is there any functions?

[maiden wadi]

This conversation kind highlights aliases. #blueprint message

All classes can be named via their relative path in the project. Some stuff like GameMode's arguments in the URL support aliases that you can specify for shorter class names, but I've never looked into how they work. May be automatic. But you can utilize SoftObjectPath stuff to convert a thing's string into a softobjectclass which can then be loaded or resolved to work as a class.

[compact hornet]

🙂 thanks for the help!

[trim matrix]

Ahhh wow I never saw that function So If i used that don't need the 'map' variable anymore?

[maiden wadi]

Depends on what you want. I'm not personally a fan of using strings to do things unless it's necessary.

[trim matrix]

Yeah me too but it's necessary in this case 'cause it's prevent to use switch

[cyan mortar]

I created a variable, but why can't I set another additional flag in its properties?

Hey, trying to get the cheat manager working in my Dedicated Server Project. It won’t seem to work.

Steps:

• I have sub-classed from the standard Cheat Manager
• Created a custom function with test strings for successful fire
• Enabled Exec. so that the function can be called from console
• Added this custom cheat class to the cheat manager in the active PlayerController
• PIE and attempt to call function via console command
• Error, command not recognised (but it appears in the drop down)

Any idea why? Do I need to set something up on the server? Do I need to enable cheats anywhere? Just trying to get it working in Editor first.

[tidal tendon]

Tick is frame based so it can give different results, you can use event on timer if you need exact timed checks. Also depends on how many checks you need to do. If your checks are not needed to be always instantly applied, just use event on timer with the interval you need. Event tick is not very performance effective on blueprint

You can use event tick for things like camera shake etc where you always need a check.

[rotund barn]

oh okay, thanks

[twin jacinth]

Hey I'm not sure if it directly supports just plugging commands straight the editor console, see if this works. If it works we know what the problem is

[twin jacinth]

Actually you did mention you enabled exec which should do that

[silk bay]

What's the best way to make a beam weapon? Like a solid beam from barrel to target. Would I still use projectiles for the damage, or some other method?

[barren tangle]

hi, if i want to move instance 0 and instance 2 and instance 4 and instance 6... i have to call the last function each time?

is there a way to set the instances that i want to move? and do it in 1 call. if need them to all do the same movement at the same time

[twin jacinth]

Hate to scare you but it is looking like you might need to configure it in c++ and project settings.
I have found online there are some dodgy ways to do it in blueprint but you'll need to prefix the command with ce than your command

[hushed topaz]

That's no problem, have a lot of C++ code already

Do you have any more detailed guidance? Do I just type CE [MyCommandHere]?

[twin jacinth]

Hate to refer you to YT but this looks decent, don't think it's best practice https://www.youtube.com/watch?v=TmzC5rE_cAQ

tried to prevent the thumbnail and it showed up anyway...

[hushed topaz]

Watching the video, not exactly sure what timestamp would help? Doesn't look like this is using the cheat manager at all. Considering it doesn't work custom BP either, would this not be a mis-setup of the cheat manager?

[twin jacinth]

Like I said it's probably a dodgy way of implementing it. Let me do a little research and see what I can find

[lofty rapids]

i think if you wrap a link in <> it will get rid of the preview

[twin jacinth]

Literally just the exec should work...

[hushed topaz]

Doing some more debugging... I have made it work sending a RPC to the server from the Player Character!

So... How do you send RPCs using the console for the cheat manager...

[twin jacinth]

This is giving me ptsd of the spaghetti for my RPCs

[twin jacinth]

Is the console command triggering at all?

[barren tangle]

is there a way to make object move at the exact same time?

here we can see i have a delay

[hushed topaz]

Yes, it works perfectly using the player to send the RPC and then call the cheat class. The Function is on the cheat manager itself

[twin jacinth]

Yeah but as in when you type in the command on the console

[hushed topaz]

No, it says command not recognised

But it recognises that it is a command to call

[twin jacinth]

Now that's interesting

[lofty rapids]

an image typically doesn't show movement, but are you saying the blocks are not raising evenly ?

[barren tangle]

they don't move at the same time. but it's normal i use a lerp on each of them in a for each loop, so it's 1 after 1

[twin jacinth]

Apart from restarting unreal, no idea.

[barren tangle]

you can see by the fact they are not at the same Z position

i'm moving them on the Z axis only

up and down movement

[lofty rapids]

so it's "normal" you figured a different way ?

[barren tangle]

no 'im asking if there is a good way to achieve that?

because for me a loop is not a good way to achieve that

it's instances of an Hierachical Instanced Static Mesh

[lofty rapids]

idk how performant it is or anything about instanced meshes, but could you have an interp on tick where you set a variable and it moves to it. You would then loop through and set the z, it would move to it. Just an idea could be way off

[barren tangle]

but that would mean that all my instance are able to listen to the variable. and it looks it's not the case (maybe an advance feature?)

[lofty rapids]

i mean one variable for each, or perhaps one for all ig

but i was saying have a z that it interps to

so then you set the z and it moves to it

if you loop through and set the z's, they might go a bit closer together

[barren tangle]

that's what i'm doing now

[lofty rapids]

right but like you said you lerp which is causing a problem ?

[hushed topaz]

Might have found it... Just tried recreating the cheat manager in C++ using a replicated function and this is the error it gives me...

[lofty rapids]

well if your looping and lerping, i'm saying on tick have it interp to the location, and setting the z will make it goto the z smoothly, so by the time the loop is over all z's are set, and they will move

it's an idea instead of how you are doing it, don't know how performant that is, a lot of ticks

[twin jacinth]

Just make the exec call a replicated function

[hushed topaz]

But then I will have to create two functions for every test... Or a one-to-many function with references and parse / pass the input string...

erughhh

Back to plan A I think... Gonna get some Tomato sauce and make some Spaghetti 🍝

[hushed topaz]

Thanks for your help man 🙂

[twin jacinth]

I have an event with a finished event which is 2 different functions with another trigger function for 1 thing, spaghetti 🍝

[cursive wigeon]

Hey can anyone help me figure out what I need to look into to make a system where players can choose an option from a dropdown menu a different pattern? Think of like picking a wallpaper for an in game wall like in sims. Google is giving me ntohing atm.

[lofty rapids]

i think it should be easy as just set material ?

[cursive wigeon]

So like on clicked, set material on a ui button

Nevwr done anything like this before so idk

I imagine its simple but dk where to start

Is there like a set texture from an array of tectures kinda thing I can put in a dropdown menu

Like a switch in 1 master mat?

[languid hemlock]

Is this a bug or am I missing something?

Uniform Grid Panel is not valid if i dont add it to screen before calling reference

[scenic ember]

Hi, can anyone tell me what this error means ? I'm pretty new to this so any help would be very appreciated.

[lofty rapids]

accessed none usually means something is empty that your trying to access

for instance a variable not set, or a cast failed and your trying to access a value from the bp

[scenic ember]

I was trying to access a value from a Data Table that is used for stats in my game.

[lofty rapids]

CombatComponent is empty, somethings wrong with the variable

[tame wadi]

Hello everyone, I have a question. I'm not sure if you can help me because it's related to Houdini and Houdini Engine. But mainly, I'm not very comfortable with Unreal Engine's blueprint.

I have an HDA that I imported into Unreal Engine. This HDA has a button (mapdownloadButton), and I would like, for now, with a blueprint, that when I press this button, a phrase appears in the Unreal logs. So I created a blueprint, added a HoudiniAssetComponent, selected my HDA in the details tab, and added an OnClicked event to attach my Print. However, for now, no matter which button I press, nothing prints. Additionally, I would like to specify that it's indeed the mapdownloadButton that triggers the message display.

Perhaps I'm searching incorrectly at the moment, but I can't find many resources on this topic.

[scenic ember]

Is it possible that the data table is not imported correctly?

[signal bane]

I understand Material-Instances can be saved as assets and used, swapping some parameters. Is there a way to do that with Static-Meshes as well? In the foliage editor, I can override my material (different leaf colors), but I can't add multiple of the same static mesh into the foliage editor. Any ideas or better way to accomplish this? (I still want to keep the same static mesh, for performance reasons)

[signal bane]

Looks like your CombatComponentReference is invalid, so do an IsValid check before accessing it (looks like you are). Or within the Component, the BattleBegin function has an invalid reference

[manic vessel]

Im attaching a weapon actor to a player hand bone with a relative transfrom so the weapon is grabbed in the correct place. same with picked up weapon attachments, But I want to do a method where Im directly attatching the player hand to the attachments on the weapon using the same relative transform , So I tried to just attatch the hand to an attachment using snap to and then setting the relative transfrom of the attatched hand . But this is where I keep failing . does anyone have any advice

[scenic ember]

I tried deleting it and readding it and for some reason now it works but it still wont load the data from the Data Table.

[signal bane]

So it says "vaild" now with your print? If that's the case, is your struct "Unit Stat Modifier" being set properly before this function is called?

also you can set a breakpoint on MP Max, and look at the values while the game is running+paused

[scenic ember]

I didnt check that but now I can see that Row is not found because the debug string is visible

Thanks for helping by the way 😄 @signal bane

[signal bane]

Npnp, Is your row named an integer? I see "UnitLevel" is being converted to a row name

also you aren't connecting Out Row--->Base Unit Stats lol

[scenic ember]

oh i deleted it

[scenic ember]

I'm really sorry but I don't get what you are saying here 😦

I was following a tutorial and I think that it was basically an integer for the unit, and I was supposed to convert it to a string?

[signal bane]

Give me a screenshot of your table, and what is the value of "UnitLevel"

[scenic ember]

value of unit level is 1 (i think)

[signal bane]

Ok, that looks fine then. You see how the integer is looking up the row name of "1".

If you put a breakpoint on the GetDataTableRow, can you see the values being pulled?

[scenic ember]

actually nvm

its 0 I'm actually dumb

🤦‍♂️

[signal bane]

hehehehehe

[scenic ember]

Man, visual scripting is hard

[signal bane]

gotta use breakpoints to look at values more

gets easier over time

[scenic ember]

it works 😄

[signal bane]

nice

[scenic ember]

Thanks to you my A's are not gone

👍

[spring osprey]

Hi, can someone help find a way to make my store buy quantity/ item id join/work with my player inventory?

[scenic ember]

I think next time I should just go with the usual C++ Scripting since I actually know how to do that..

Again, thanks for the help @signal bane

[signal bane]

I think learning both is the way. You can't do everything with only C++. Sure np. Also I recommend this video if you like C++: https://www.youtube.com/watch?v=VMZftEVDuCE

You can do most things in blueprint though imo

[trim matrix]

What would be the best way to make a projectile (arrow), that will ignore everything (colision and other actors), but the target it goes to?
Currently I have projectile that is beeing targeted, it's flying to the target, and it doesn't collide if the unit is ally, but at the same time it does collide with other ''arrow/ball" when I throw it again. The question is, what. in the simpliest way to make it, so if there is set target on projectile/arrow, it will ignore EVERYTHING, but not the target and it will hit it no matter what? On the screen you can see, ball is blocked by ''ally'', but when next ball is coming, it will explode (doesn't deal dmg because it collides with itself. It works with the ''enemy'', as it will hit it and dmg and destroy itself, but I have hard time thinking of making it more simple which is basically, ignore all, but target. Or will it actually be more complicated than I think?

[hollow lagoon]

Is it possible to trigger an event when a player leaves or enters any trigger box ? not just one specific one ?

[tight pollen]

i set Don't Spawn If Still Colliding, but it spawn

[rose crest]

yes

[tight pollen]

and I see how an object with physics turned on overlapping another static object

how can i fix it?

[hollow lagoon]

how ?

[rose crest]

i'd use interface to message all actors with interface/class

you still use collide

[rose crest]

does it have collision box or just mesh?

[hollow lagoon]

sorry, I'm very new to programming so not sure what that means

could you explain in terms of nodes to use ?

[rose crest]

it's not really about nodes, Your character need collision sphere or anything to dectect overlaps, then just get overlaped actor, check if it's proper class or have interface and use interface message to trigger event on all actors of class/with interface

or other way around, have box detect player and send message to all other boxes

[hollow lagoon]

hmm maybe I'm not approaching what I'm trying to do the right way

[rose crest]

there aren't many nodes used, just get actors with interface/of class and message. From event side just implement event from interface

what do you want to do?

[signal bane]

any help on this one?

[hollow lagoon]

basically I'm trying to tell the player when they're approaching the world border, it's easy enough with one trigger box, just show a widget saying "close to world border" when in the trigger box, and remove it when outside of it

the problem is when I have several overlapping trigger boxes

(since I need 5 to cover the shape of my map)

on the overlapping triggerboxes it's just getting confused

i.e creating multiple instances of that same widget

and not removing it when stepping out of the trigger box

sorry, I hope I'm explaining this well

[hushed pewter]

you could have the player see if they're overlapping another "World border triggerbox" when leaving one of the overlaps.
Using GetOverlappingActors with those trigger boxes as a class filter.

[tight pollen]

just mesh

[rose crest]

i don't know really, does duplicating it with new material cost that much performance?

[signal bane]

I wanted to have 5 varations, so I would like to keep the same mesh for instance purposes

[rose crest]

just do it as said, if its actor just implement interface in class setting with function "warn player end of the map" or sth and call if if he enter it and another one to remove. Or just simple make call for begin overlap/end overlap

and use the same box multiple times, even't will work for every instance

[hollow lagoon]

cheers, Ill give that a go :)

[rose crest]

collision preset probably, try custom, block all for everything and check if mesh have collision at all

[rose crest]

You can have actor with random material applied at creation. NVM, i found a way

5$ xD

in folliage painter, paint whatever you want. then Save instance

then you can add same mesh again and overide material

[dusky cobalt]

Guys, I need small tip! I almost made it work. Right now, the projectile (ball), is only exploding when it's colliding exactly with the target that was set. The problem is, that when it's other actor in the way, projectile will just stop on it (since it's not the target).
The code so far looks like this.

Before I check maybe if I used get overlapping actors would work better here, I wanted to ask you for hints.

[rose crest]

are other object actors or meshes on map?

[dusky cobalt]

What do you mean? 😛

[signal bane]

Awesome! that worked great, thanks~

[rose crest]

np

[rose crest]

this blueprint bool, why compare it to target?

[dusky cobalt]

I want the collision and the explosion to happen only if it's colliding with the target, like I don't want collision to happen with everything, but the target if that makes sense.

[rose crest]

Ok, that confused me because you said it stops on others. So how should it behave with others?

[dusky cobalt]

It should ignore everything

and go straight to target

like auto aimed bullet let's say

[rose crest]

Maybe create new collision preset and apply it to target

And set ball to ignore everything but that preset

[dusky cobalt]

I will try, good idea

[barren tangle]

Hello, We can't put a break point inside a Timer by Event ??

[proud sentinel]

what does component activation do, and if i bind to its event when does it activate in relation to constructor and begin play?

[barren tangle]

i know i'm there because my actor move, but it doesn't stop

[rose crest]

while or for loop with break?

and make timer as variable, and invalidate it then you finish

[barren tangle]

the timer will never finish here, but the fact is that i would like to see what i have inside my calculted index

but i can't because the breakpoint are not reached

[grim sand]

Alright time to disect another poorly documented node in BP. What does the Set Show Mouse Cursor node actually do in the player controller beside turning the mouse visible.

I notice that if I use this node, and click with left/right mouse button, I lose control over my pawn. Why is this?

[rose crest]

You can use loop with break to break it when it reaches certain value

Then invalidate timer when it completes

Maybe I don't get what you want to achieve

[sand lark]

Beginner to Blueprints in Unreal and Programming in general. I'm trying to set up a Reload timer that shows up on the Player Hud. I have a reference to the "reloadSpeed" float variable, and "reloadMaxSpeed" float variable. At the start of the game I set my reloadSpeed float to reloadMax float, and have a boolean "canReload" that looks if the Player's Current Ammo is "not equal" to their Max Ammo, and then lets them reload if that is true, it then sets their Current Ammo to their Max Ammo.

That's working well.

However, it's hard for the player to know how long they have until their next reload, and I want that to be a variable that changes if the player picks up a powerup that decreases the time it takes to reload their weapon. I'd like to have it where their reloadSpeed float needs to equal the reloadMaxSpeed value before the canReload boolean changes to true.

My thought was to use a Slider in the WBP_Hud that I created but I cannot for the life of me figure out how to use Delta Time with a Float properly, or if that is how you even do that. Any tips/suggestions for nodes to use?

[rose crest]

Probably goes to click events. Either for specific mode like rats games or menu clicking

Do you have input set to game only or game and menu?

[grim sand]

Neither, I just left it as default and have changed the class defaults to show mouse cursor by default. I find it perculiar that this bool changes so much in terms of functionality.

In a scenario where we have buttons for time control on the screen in the game UI, we would want players to be able to click those, without losing control of the camera pawn right?

[rose crest]

You need some kind of time flow. Either event tick, I know it's bad but for something that small it's ok or timer by event. Or timeline node

[rose crest]

I try to find situation when you want to control camera and UI at the same time

[sand lark]

I'll look at the timeline node, thanks!

[grim sand]

Right, I might just make it different then I suppose. Players will have to hold either right click or a different button for camera rotation to work, then if they do not, they can interact with the UI as normal.

[hollow lagoon]

Hello again ! Is it possible to edit a blueprint in the level itself ?

[rose crest]

Edit level blueprint

[spring osprey]

why if I copied everything (ctrl+c-ctrl v) the second one doesn't work?

[hollow lagoon]

thankies !

[barren tangle]

i put a break point, but it doesn't stop. my question was is timer doesn't allow to reach the breakpoing?

[hollow lagoon]

where is that option ?

[rose crest]

In main editor window, not blueprint, there's icon on top with blueprint, click and find it there..I'm on phone and can't make shot

[rose crest]

You need to specify it when it's breaked. Must connect execution pin based on some comparison (branch)

[barren tangle]

mmm i don't understand

[dusky cobalt]

If anyone will need in the future: Solution: Set overlap all on preset, and then the code should look like this. It ignores everything, but not target, just as I wanted.

[tight pollen]

how to check which side of the door the AI ​​is on?

for the player I do it this way

[rose crest]

Add arrow to doors

[grim sand]

Just to make this visual for you. Take a look at this screenshot.

When we run the for each loop with break macro, we check each loop if something is true about the array element we are inspecting. If it is, we can connect the execution line to the Break input to stop the for each loop from continuing its functionality.

[tight pollen]

What do you mean

[rose crest]

Arrow component to door actor

[tight pollen]

ok, but how is this going to help me?

[hollow lagoon]

oh, sorry my question was moreso, if I have a blueprint with two cubes, could I drag the cubes around in the level itself instead of having to open the blueprint to edit the cube's location ?

[rose crest]

Nah, it's one actor

Make 2 actors with 1 cube

[hollow lagoon]

cheers ! Ill do that

[rose crest]

Not make,place..if it's the same.functionality

[grim sand]

Just for technicalities; You could do this, but it would involve setting up exposed vector variables inside of the actor, enabling the 3D widget setting, and then in the construction script setting the location of each cube to the world location of each exposed vector variable.

There aren't many scenarios in which this approach would be justified though 🙂

[manic vessel]

If I position an actor in a character hand and get the relative tranform , How Could I also use that transfrom the other way around and attatch the hand the the actor with the same relative transfrom

everthing I have tried has failed to give proper results

[rose crest]

Wouldn't it involve procedural animation?

[warm oriole]

Considering that #game-features-system is being archived I wanted to ask here:

What kinds of features/content should be made within the GFS vs the normal content folder? For example, let's say I wanted to have an open world game with progression based events (ie. only after X boss was defeated). It seems like GFS would be a great way to do this as you could simple enable an event after a specified progress point and have it spawn the event as needed and add the respective enemies to some world enemy spawner.

This makes sense, but I'm wondering if this logic would also apply to a player's combat system. Assuming you are using GAS as well, would it make sense to have the player's core combat (ie. melee attacks) be built around GFS and added to the player, even if they are never removed? For multiplayer games, it'd make sense to use GFS for combat as your player could have many states, but in an RPG it might not.

Hoping for some clarification here and confirmation that my thinking is correct.

[hollow lagoon]

interesting ! Way beyond my skillset but I appreciate it 😄

[rose crest]

Or editing bones to attach points, I'm not really experienced in animations

[tulip anvil]

only difference i see is its using a different interface.

[modest monolith]

How to make "Joins after seconds" go unhidden after I check the box? Is there some sort of "On checked" event I can use?

[barren tangle]

but it's not a foreach

[rose crest]

Bool

[barren tangle]

when im talking about the breakpoint it's thata

[grim sand]

Okay, so then do the same thing but then with the For Loop With Break?

[rose crest]

Same methodology for for loop with break

[barren tangle]

where come that break lol

[grim sand]

Right, you are talking about a debugging breakpoint

[rose crest]

XD

[faint pasture]

What do you mean by "reload timer"?

[rose crest]

Select instance at top to monitor it

[faint pasture]

what would a reload timer of 0.5s mean?

[barren tangle]

so the normal node doesn't allow the breakpoint?

[grim sand]

That happens during runtime, if your code flow runs into the ForLoop. It will pause runtime and navigate to the node that triggered the breakpoint. This happens automatically as far as I know.

And if it isn't triggering, then it means your code flow isn't reaching that node. Which means to enable breakpoints earlier in your flow until you find the problem

[tulip anvil]

no

[spring osprey]

yeah I've changed it but its literally the same interface duplicated

[barren tangle]

ok, because i was sure i'm into the node beacause my actor move, but i was not stop

[tulip anvil]

does it work if you change the interface back?

[tulip anvil]

wait, are you expecting both to run at the same time?

[spring osprey]

they can't?

[rose crest]

Why?

[faint pasture]

Does the thing you're hitting implement the 2nd interface?

[tulip anvil]

they dont have the same name

you need to call both separately

[faint pasture]

Do 1 line trace and do 2 interface calls on the hit thing, if that's really what you're after

Hit the thing -> tell it Interact -> tell it Consume

Although 2 interfaces like this is really a code smell.

What is meant to be the difference between them?

[spring osprey]

What I want to do is make one for "interact" and another for "consume"

[faint pasture]

Does the same input do both?

[spring osprey]

nope

different inputs

[faint pasture]

ok then do that

[tulip anvil]

have both inputs trigger the same code

[faint pasture]

add a 2nd input that calls the 2nd event

[manic vessel]

The object is attatched to the hand bone & I have a ( relative transfrom ) how can I get the opposite of this transfrom if I wanted to instead attatch the hand to the object?

[rose crest]

Then get target from line trace and store it. If you input make it behave accordingly

[faint pasture]

What is the gameplay purpose here? What are you interacting with, and what are you consuming?

Why doesn't interaction with a consumable just consume it

[tulip anvil]

could be a consumable in the world, like a location where you can attain a buff

[faint pasture]

and what does interaction with the thing do?

[spring osprey]

one button is for putting the item in the inventory and the other to consume it

[faint pasture]

ok

that makes sense

I'd make a single interface and probably just give it 2 functions, ShortInteract and LongInteract. Do a lot of things have this sort of mechanic?

like weapons, is it pick up / equip?

[dusk yew]

Hello guys, a question when I stop owning a character to own another, is the first character left without a controller or is it taken over by the AIController? I want to make it possible to control a PET but when it is not controlled it will follow me

[rose crest]

You can attach ai controller to it

[spring osprey]

nope, only pick up battery for flashlight and eat to heal

[rose crest]

When you line trace you can store actor in var. Then when pressed consume or interact with that stored var

And when you end trace make var empty

There are multiple ways to do it. One interface needed really

[spring osprey]

and how can I do that? I am new with UE 💀

[rose crest]

Wait, I looked at screen. To be honest it should work as it is. Does it print?

Does target have event assigned for consume?

[spring osprey]

interact works fine but when I duplicated it to "consume" it just doesn't work

[faint pasture]

Show your current code

[rose crest]

When you press button for consume, does it print? Do you have input mapped?

[faint pasture]

Do you have a 2nd input?

[spring osprey]

enhanced input? yes

[rose crest]

Input action

[spring osprey]

yes

[rose crest]

So it should print Hello when you press it, what about other side. Does it print when called by message?

And put debug breakpoint on consume message. See if it have proper values

[spring osprey]

the two print its just that the line trace just doesn't work in the consume part

[barren tangle]

need help. I write that.

Column and roaws both = 5

i expect to have 5 print betwen 0 and 35

but i have only 1 print, value between 36 ad 41

lol

[rose crest]

Do you print I loop body?

[barren tangle]

yes

[spring osprey]

okay now the line trace pops up but it looks different I think that's why it doesn't work

the one with balls is the one that works (interact)

[barren tangle]

i go it

and i need some rest for today 😄

[rose crest]

Did you lie? XD

[barren tangle]

no, it's just after a timeline

[dark drum]

What else is on the loop body?

[barren tangle]

my timer = 3 seconds and my timeline = 3 sec as well

and i'm connected to the Play froms start

so i assume it's restart before finishing the timeline

but why the value will be between 36 and 41..

i give up

[rose crest]

It prints last index

5*6+ from 0 to 5 is 36-41

[fierce timber]

Hey is there a way in Common UI to Display Actions in Action Bar without define the Key on a Button? Because at the current state i have to move the button out of the viewport so that its displayed in the ActionBar without showing the Button

[barren tangle]

index 1 doesn't start to 0

yeah yeah

i'm tired

best things to do, take a break for today 😄

let's go play Solo Leveling

[rose crest]

Take a nap

[barren tangle]

already 11PM.. it will not be a nap 😄

[rose crest]

THE nap

[barren tangle]

and i had in mind that each loop will create it's own timeline lol 😄

with the dark side of the force it was possible

[modest monolith]

I've put that I can change the float variable of a blueprint via widget.. but when I start the game that variable is not changed.. why ?? print string works correctly

[elder pewter]

what's the idiomatic way to test out different versions of a blueprint? for example, if I want to try creating a version of my blueprint actor (placed in a level) where a single node is changed, but still be able to revert back to the original, is there a way to do that conveniently? I assume I can just undo and redo my changes back and forth, but that seems inefficient and potentially destructive if something goes wrong

[rose crest]

default value will always be called on start unless you save it in game save file

[modest monolith]

not true... if you change the default value..bte im changing instance variableù

[spark steppe]

make a duplicate of the BP before you make changes as backup, also allows you to compare quick between old/new and you can copy over code from old/new

[modest monolith]

Why my variable value doesn't change?

[lofty rapids]

does it goto true ?

[modest monolith]

yes

[lofty rapids]

did you try to make sure what was comming out of get value is correct ?

[rose crest]

you get actor but need eithert to cast of message

you need to specify which actor

[lofty rapids]

Also is there only one of those actor in there ?

[rose crest]

"that" exacly

even if its one it will go to void

use interface and pass float with message

[modest monolith]

Yes

[modest monolith]

I don't need to if there's only one

[rose crest]

if you get all actors of class maybe

[lofty rapids]

i would look at that get value, make sure it's what your looking for

[idle vigil]

what do you think is the best naming convention for blueprint interfaces? I considered using BPIF_ or IF?

[rose crest]

there's none, most of people use BPI_ xxx I think, whatever suits you and you stay with it

[idle vigil]

i like bpi

[gaunt monolith]

Hello everyone! Trying my first ever project on UE5, can i ask here for help with blueprints that i can't find online?

[tulip anvil]

you can ask for help but nobody here will freely help you put together any blueprint you want. there is an expectation for you to try and do things/make things/learn things yourself as well. if you run into roadblocks or struggle to figure out how something works or trying to resolve a problem or the likes people here will gladly help you in most cases.

[gaunt monolith]

Well i've been trying to follow this guide to create footsteps sound for my first person character with no mesh/animations https://dev.epicgames.com/community/learning/recommended-community-tutorial/WzJ/creating-first-person-footfalls-with-metasounds But i think it's outdated. I can make everything work except the footsteps sound immediatly start as soon as i start the game and only stop if i both jump and move forward at the same time. Can't find solutions online, i'll send some screenshots of my code, let me know anyone can help me figure out what's wrong.

[dreamy mountain]

hey, so im trying to make a buyable door using a blueprint, but i dont know how to do it basically

i have this, but the widget appears even outside of the box

[rose crest]

You cast to bp_player, yet dont follow with it

[dawn gazelle]

Footsteps are usually something you'd build into notifies in your animation rather than having the game logic itself trigger whether a footstep sound should play.

Let's look at your logic though:
Your movement input's "Triggered" event fires every single frame, checks if the player has velocity and is not falling, and if so, enters your DoOnce node which then calls to play the audio.
So only if your player has 0 velocity or is falling will your branch ever go to false to stop it.

[dreamy mountain]

i fixed the widget part, but not the interact

[rose crest]

i understand its door blueprint?

[dreamy mountain]

yep

[rose crest]

it must be, change input action for event and call that event when interacting

[dawn gazelle]

Player Input is normally only routed through the player controller and its possessed pawn.
Any other actors in the game would not receive any input events.
To circumvent this, you can "Enable Input" on the actor which will then pass the input from the player controller to this particular actor.

A better way however, is to pass an input event manually from the player controller or its possessed pawn and call a function on the actor, just so you're not having to enable and disable input on a whole bunch of actors.

[dreamy mountain]

im confused, sort of, hang on

lemme try something

[gaunt monolith]

Yeah, but since i don't have animations i followed the guide linked, otherwise i know how to put the sounds into the animations.
About the logic, so shouldn't it not play if the player is completely still? Because it does play as soon as i start the game, when the player is staying completely still.

[dawn gazelle]

Likely because the player doesn't have 0 velocity or is considered falling (spawned slightly above the ground?)

It's also not great to use comparisons with floats to verify if it is 0 or not, as 0 in a float could be getting stored at 0.000000000004 which isn't 0.

A better check may be velocity -> legnth > 0.0 && movement mode == walking (or whatever the default ground movement is, I can't remember)

[gaunt monolith]

So, let me understand, i've started coding since just a few days ago so i might be slow... instead of get velocity -> vector is zero i should get velocity -> vector lenght...?

[dawn gazelle]

Yes, getting the vector length of the velocity gives you a total of how much motion there is between all axes, which is something you can check if it's greater than 0 to know if it is moving.
The other part of the problem is if your movement input isn't firing, then the audio won't know to stop as your current code only executes if the movement input is being pressed.

[elder pewter]

if i have some tick logic which manipulates some variables across a series of nodes, and some input action logic manipulating the same variables, can there be a race condition between the two? or will the input stuff wait until the current tick finishes and/or vice versa?
(i guess this question isn't really blueprint specific, unless i'm missing something)

[gaunt monolith]

Hm, i might have to redo most of the code then. Another small things first, most of the guides/tutorials to help me in these use a different movement input, the old version i'm guessing (first screenshot). I'm using the EnhancedInputAction one (second screenshot), will it create problems do you think?

[dreamy mountain]

so would i make a custom event in my player blueprint which calls a function in the door, or is it the other way round?

[rose crest]

custom event or interface event

start with custom event and call it when character overlaps it

you will have to cast to bp_door or how you call it, and from cast pull event name

[dreamy mountain]

ohhh

ok

[dawn gazelle]

Yes, you're correct, the first is the old input system where the new way is using enhanced input. It shouldn't specifically cause a problem other than the "triggered" output pin on the enhanced input system will fire for both movement input on the forward and the right axis where with the old system they were seperate input events.

[rose crest]

if you make it work try practice with interfaces, they work better in larger scale and are more flexible

[dreamy mountain]

never heard of interfaces

[rose crest]

cast is like "send to one specific" and interface is "send to many/specific"

[gaunt monolith]

whenever i read up a guide they always connect both the movement inputs to the code to add footsteps, but i can only connect the last movement input, so i was worried that would cause problems, but it's good it shouldn't, might make it easier for me.

[thin panther]

No. Interface is still sending to a specific instance

You just don't care about it's base class, you only care if it implements a behaviour

Sending to many would be a dispatcher

[rose crest]

get all actors with interface>message

[thin panther]

No

Why

Would you do that

That's just reinventing a dispatcher but worse

[dawn gazelle]

Casts are checking if the object fed in of a specific class and if so, allows you to access the speciifc functions or variables available to that class.
An interface is a generic means of communicating with a variety of objects that may not share any common base class. An interface must be implemented in any class that you want to utilize it, otherwise default return values are returned from the interface or no functionality executed by the object that you've passed as the target for the interface call.

Both require an valid object passed in for them to work.

[thin panther]

An interface is when you want class agnostic behaviour or an abstraction layer to prevent things from relying on each other.

For instance, if it shares behaviour over a number of base classes, or you might use an interface for say, opening a web browser, because you don't care on the specific implementation, you just care if it can do the thing, and then you're not coupling yourself to such a specific thing.

A dispatcher is for communicating with many things. It's like broadcasting over radio that something happened, and anything that cares can tune in and listen for the message

PIE: Error: Blueprint Runtime Error: "Accessed None trying to read property Door". Node: Buy Graph: EventGraph Function: Execute Ubergraph Player BP Blueprint: Player_BP
idk what id do here

[dawn gazelle]

Accessed None == Your variable is empty.

[dreamy mountain]

ah

i see the issue

[dawn gazelle]

You've created a variable of type "Door" but haven't set an instance of a specific door in that variable.

[dawn gazelle]

Doors don't technically exist until run time.

[dreamy mountain]

fixed it, but i also have this new issue

did that at the end to fix it, but when i start the game, it shows the widget text as if i was in the collision box, which is weird

[rose crest]

yes,. but there are usages. At last for me now. Maybe in the future I'll get more experience to use different method

[dreamy mountain]

see what i mean? no where near the door (white box in distance) yet text is on screen until i hit start

only thing that references the wbp is the door

[thin panther]

That's not getting all actors with interface though

What can be good for things like that is something like a sphere trace

Or even a multi sphere trace if you're so inclined

[rose crest]

what I meant was using array as target easily, my bad, sry

[thin panther]

Ah no, that's a perfectly valid usecase :P

[rose crest]

uff, saved xD

[sharp steppe]

If a boolean is false, is there a way (or a node) to find the name of that boolean variable?

[dreamy mountain]

wdym

if you know the variable, you can use a branch node and do things based on if its true or false if thats what you mean, might be me misreading because im tired but

[sharp steppe]

If I am checking hundreds of booleans, and if one is false, I want to display the name of the false variable

[stoic ledge]

you want the bools variable name as an output to print screen?

[sharp steppe]

Yes

Using blueprint

[dawn gazelle]

There's no way that I'm aware of to read the name of a variable in blueprints alone. All you can really do without some C++ is create something that branches to all your bools and then print the name (manually)

[dreamy mountain]

i have a weapon wallbuy and a buyable door, both use the same interact wbp; how would i change the text depending on the blueprint its created by?

[dawn gazelle]

Your implementation can differ on different classes. If there is some form of heirarchy between these items, then your interface could say, print out a specific variable and then you just need to set that variable to a different value on each child.

Otherwise, you'd just have the implementation do whatever you want on each actor.

[dreamy mountain]

there wont be an overlap in them both being available at once

i just need to change the text depending on which blueprint created the widget

[sharp steppe]

This is a solution, but when dealing with hundreds it’s very time consuming. Last resort I guess. Thanks as always!

[dawn gazelle]

Feed in the value when you're creating the widget.

[dreamy mountain]

where would i set the value though

[dawn gazelle]

In the widget

[sharp sigil]

How come my static mesh components are returning None when I try to get their attachment?

Also their relative location returns world location

[dawn gazelle]

This return value is a reference to the widget that was created.
You can use that to set properties or call functions within that specific instance of the widget.

[dreamy mountain]

ahhh ok

[dawn gazelle]

If you wanna get really fancy, you can set properties as "Expose on Spawn" and then on the create node it'll actually give you an input where you can set the value to whatever you want.

[sharp sigil]

Even this doesn't work >.>

[dreamy mountain]

wheres that

found it

[rugged merlin]

I'm not sure whether this question has been asked in here, but is there a way to get the direction between two vectors in degrees? I want to compare a velocity from a previous tick with the current velocity and see if their directions are more than 90 degrees apart

I know about Get Unit Direction, but that just returns the difference between the vectors (assuming I'm understanding it correctly)

Or would there be a way I can use Get Unit Direction to do this?

[spring osprey]

Hi, I want to make a consume interaction(add more battery when picking X object) for my flashlight like the interact one I have but don't know how to make it, any help?

[rain wraith]

Is there no BP node to Set Bone Transform for a Skinned Mesh Component? There is a get node for the Skinned Mesh Component bones, but none for set; I can only find Set Bone Transform nodes in BP for Control Rig and for Poseable Mesh Component which arent compatible with Skinned Mesh Components

[dawn gazelle]

I believe dot product is what you want.
Dot product of 1 = vectors fully aligned.
Dot product of -1 = vectors fully opposite.
Dot product of 0 is perpendicular regardless of direction.
So if you wanted to see if a vector was more than 90 degrees apart, it would be a dot product between values less than or equal to 0.

[lunar sleet]

Can you set location, rotation, scale separately?

[rain wraith]

Hm? Not sure what you are suggesting, there's literally no nodes to set any transforms for the bones

[lunar sleet]

I was asking if only the xform node was missing or all of them

[rain wraith]

There are no nodes for setting the transform, or any individual components of the transform for the SkinnedMeshComponent bones. I only see nodes for getting that data

[lunar sleet]

Yeah people online saying you need to use poseable mesh ig

[rain wraith]

Oof okay that's beyond me cause this is for VR hands so idk how to copy all the code functionality from a skinned mesh to a poseable mesh

Thank you though

[rugged merlin]

Thanks! I didn't know dot product could be used that way

[queen dagger]

ok so im at the point where im trying my hand at ai again and am running into issues cus im using paper 2d

can you use blueprints in an AIcontroller bp to pass inputs into a character?

or do you have to use bp in the character itself to identify where the enemy is and how to move

for instance can you write in the ai controller if enemy is to right add action value of -1 for input to move left

[ripe comet]

found a really nice custom dungeon generator plugin, got it working. now just to implement it into the main game

[teal tendon]

Hey guys I was using the sun position calculator plugin and was using sunrise time, sunset time and solar noon time to differentiate between morning, afternoon, evening and night but the problem is the sunrise time is coming in negative any idea why is this happening and how do I solve this issue

[lunar sleet]

If it’s just got a minus in front of it that’s an easy fix

If it’s not at all what you want it to be, might need to read the plugin’s docs or contact its creator

[teal tendon]

ok

[barren tangle]

Hi, I would like to move an array of actor with the same movement using the same timeline. is it possible?

[lunar sleet]

A table of actor?

[barren tangle]

a array of instanced static mesh

[lunar sleet]

Are you trying to say an array of actors ?

[barren tangle]

yes sorry, table is the word in french, forgot to say array

[rugged merlin]

I'm pretty sure you can do that, right?

[lunar sleet]

Don’t see why not

Just take the track or the value of the lerp, and for each loop on the array

[barren tangle]

how could i achieve that because that?

because the timeline will restart if i use the same inside the loop

[lunar sleet]

The timeline wouldn’t be in the loop

[barren tangle]

for the moment it's like that

[lunar sleet]

Read what I said initially

[rugged merlin]

Why is the timeline in a loop

[barren tangle]

and i can't define the timeline to be specific to my instance

[lunar sleet]

And bear in mind that a for loop needs to run in one tick, you cannot have latent actions in it

[lunar sleet]

Your code is backwards

Timeline first, then the for loop

[barren tangle]

if i do timeline first. the forLoop will be fast enough to move all of them at the same time?

[lunar sleet]

I guess you did actually mean table. Weird but 🤷‍♂️

[barren tangle]

ok, i will try

[rugged merlin]

I found a forum post that says the same thing neoexcidious was saying

Put the timeling before the loop

The update pin on the timeline should be connected to the loop
