blueprint

[odd ember]

test it on the array you constructed

[timber cloak]

already

[odd ember]

otherwise you're not testing it properly

[timber cloak]

it printed out

but player isn't getting it

[odd ember]

I don't see the printout anywhere

[timber cloak]

wait

i just restarted the project

it's HDD and old pc

[odd ember]

a restart won't fix broken logic

[timber cloak]

[odd ember]

you had 10 entries in your list yes?

11 in fact

it's only counting the first 6

[timber cloak]

https://imgur.com/a/B0709ia

because it's 6 players total

by right, this logic should work, right?

[odd ember]

I guess it may be a replication error then

[timber cloak]

bug then?

[odd ember]

no as in you're not replicating them to the client

but I'm not big on multiplayer

[timber cloak]

but in server isn't getting it either

even it fails, the server should be able to get it

[odd ember]

server has them as per your screenshot

[timber cloak]

well, just assume it's single player. GameMode to first's screen = no replication needed

wait

[odd ember]

but also if you're using multiplayer you should use player state and not player controller to store info

have you read the multiplayer compendium?

[maiden wadi]

The string needs replicated. The server won't automatically send it just because it's expose on spawn. So that string only gets set on the machine that it's created on, IE Server.

[timber cloak]

https://imgur.com/a/fvxccj5

no player controller/state is needed unless you need them

[dawn gazelle]

What's probably happening, is that there are characters being spawned, but they are not being possessed.

[maiden wadi]

Also advise not replicating string. Replicate an integer and make a string array and select out of the array via the replicated integer.

[timber cloak]

gamemode is will still prints it to SinglePlayer, but Singleplayer not working as well

the server = singleplayer

[odd ember]

so, back to enum 😂

[timber cloak]

it is possesed by default

[odd ember]

setting its owner is not the same as possessing it afaik

[maiden wadi]

Possession and owner have no bearing on that string. You just need the string to be replicated, and set correctly, and for it to only be spawned on the server.

[timber cloak]

yup i made the game "Offline" now, nothing prints out

wait let me read all the messages

[timber cloak]

the String variable in ThirdPersonCharacter, replicated already. I even tried RepNotify, nothing.

[odd ember]

is the server array set to replicate though

[timber cloak]

yup i tried that earlier, same result

btw i read Array cannot be replicated unless it is on struct

so no point replicating an Array

[maiden wadi]

Where are these being spawned?

[timber cloak]

GameMode

fruit box(the string array is in gamemode), fruit22 (string variable in thirdpersoncharacter)

simplest thing with simplest logic but the engine isn't printing it out

unless i failed somewhere

[dawn gazelle]

Possession does matter in this case, as he's spawning characters and his PageUp is probably on the character themselves. Any automatically spawned characters from the PIE wouldn't have the values set, meaning when hitting page up, he would get blank prints.

If he possesses one of the spawned characters, it'll probably show up.

[maiden wadi]

The only thing that would matter, is whether or not pageup would work.

[odd ember]

or nevermind

but there is a mapping issue there

[timber cloak]

But apparently that works for enum though. Possessed usually means the Character is controllable.

[maiden wadi]

Go into your character's Beginplay, and print the string.

[timber cloak]

What requires the "Possess" node is when your World Setting's Default Pawn is "None" in value

[maiden wadi]

It should print the same string for the server and client version of each pawn. If you get a bunch of client prints that are empty, your string isn't replicated.

[dawn gazelle]

See, he's spawning additional characters.

[timber cloak]

there's no extra characters in the level

[dawn gazelle]

You are spawning characters, and your world's default pawn is set to what?

[timber cloak]

set to ThirdPersonCharacter

[maiden wadi]

Ah. I see what Datura is saying now.

You're likely possessing the wrong character who hasn't had it's string set yet.

[dawn gazelle]

So, when you are launching the game, the game will automatically create pawns of ThirdPersonCharacter for the number of clients you selected.

Then you are also telling the game to spawn more characters.

[timber cloak]

already, the input is actually on the Character's BP. Input to Print String

[timber cloak]

okay wait let me try with Possess

[dawn gazelle]

If you set your default pawn to none, use this node and you can spawn the characters with the values, and use the new controller pin on this node to posses the player.

[timber cloak]

Same thing, except 1 of the player will be disconnected

yup i used that

[orchid thicket]

how come i thought it was hard to learn how to use unreal

[timber cloak]

let me show

wait

[orchid thicket]

and after watching like within 3 days like 12 videos

around 5 min

i already know the basic shit on how to make a game

[twilit heath]

@dawn gazelle HandleStartingNewPlayer is better, it works after Login and after SeamlessTravel

[odd ember]

so you're saying you know basic game vocabulary, and you're now able to go and reproduce the game equivalent of the works of shakespeare?

[twilit heath]

PostLogin is specific to connecting for the first time

[orchid thicket]

not really Xd

[timber cloak]

https://imgur.com/a/I5DrDUn

[dawn gazelle]

Ok, good to know, thanks 😄

[orchid thicket]

but i know how to kinda

determine what does wahat

[timber cloak]

never worked even with Possess, one character disconnects as a result

even Offline mode still never get the fruits

by right the logic is correct, right? anyone can clarify?

[royal rain]

hey so with the ball rolling starter kit thing i wanted to know if there is a good way to try and have more control over the ball, also the ball has some infuriating physics a lot where even on flat surfaces it bounces up

i tried to give more of a higher negative number when i am able to turn more left and right

which kinda worked and its almost there but still could get annoying espically when the phyics breaks and the ball goes 10 feet in the air for no reason

and is there a reason why building my game crashes? should i get a new update maybe

[dawn gazelle]

Sadly no. What you're doing is adding your newly connected controller to an array, then looping through your fruits array, **checking if your player controller array has a valid index at the index of your iteration of the fruit array, getting the value of the player controller at that index, and spawning a character with that controller as the owner, and possessing it with the newly connected controller. ** Since you're still iterating through an array, you're basically doing the bolded section over and over again for each fruit.

[random hill]

Any advice on that question?

[dawn gazelle]

and since each character that joins calls this, they each do the same thing.

[timber cloak]

https://imgur.com/a/Isk1ZnN

like this?

[odd ember]

no

don't do that

what I said

was in error

like stated on the very next line

[timber cloak]

ok

[maiden wadi]

@random hill You can either create a whole new tree, or better is to create subtrees. You can run new behavior trees from other behavior trees, and this lets you easily branch out major logic into new areas and keep your code in a contained way so as to be easily modified for different types without having one huge gigantic branching tree.

[timber cloak]

let me read that paragraph

[timber cloak]

but as an end result, it will definitely as least give a fruit to the players, right?

Also, i did put a print string right after the "spawn", so i can see the loop results. It didn't iterating or do infinite loop

[random hill]

@maiden wadi yeah, the issue I have is... a simple enemy has what. Follow, attack and wait. But a more complex will have also use special ability 1 and 2, heal etc. So one way would be to make a node" do action" for the single tree, and that would be dealt with in the enemy BP. It would have to prioritize etc.

But I don't think that's the best option

[dawn gazelle]

This would give each player that spawns into the world a fruit, so long as you have your default pawn set to "none"

[timber cloak]

let me try that

[random hill]

@maiden wadi so you think that I should make one general tree with most of the behavior like following, maybe running away etc, and where the "attack" is, I would do a subtree for each enemy? So a peasant will only attack and that's it, but a mage will choose a proper spell and cast it?

[royal rain]

im sorry if my stuff is really simple, idk where else to ask and i might not be that good at this

[maiden wadi]

Possibly. I mean it really depends on your project and your design preference. If you're going to have a lot of different AI styles and they're not all going to be simple, I'd vote for different trees. Just don't end up with this.

[timber cloak]

um, no results still

that code, it looks correct logic to me though

[maiden wadi]

To be fair, you can possibly get away with branching the logic in the same task too. Just execution and preference mostly.

[odd ember]

best approach is to do nested state machines each with simplified animation state switches

it's the cheapest, too

[timber cloak]

you are right

[maiden wadi]

That was to likKrit about the AI thing.

[random hill]

@maiden wadi I don't think that would happen. I want what I described, a few enemies with mostly same behavior - except, more advanced enemies have some more abilities. Maybe except for bosses.

I will just have to figure out how to use subtrees.

[naive dagger]

Hello everyone! Please tell me how I can implement the following bundle. The camera moves behind the character only along the X axis, and does not go beyond the walls

[dawn gazelle]

It's working on my end just fine.

1. Check and make sure your default pawn type is set to None on your game mode.
2. The "Fruit" variable needs to be set to replicated on your Character.
3. Your character's print string should only need to look like this:

[maiden wadi]

@naive dagger Are you considering like a traditional side scroller camera, but without height, or?

[naive dagger]

@maiden wadi
Yes, I need a camera that will follow the character only along one axis, while the character moves along two axes

[timber cloak]

i re-test and it worked. I was sure i get blank results earlier even with "None" on Default Pawn.

[timber cloak]

to think you solved my answer after i failed to do after few days. Thanks a lot

i still can't get it what's wrong with the earlier version.

[dawn gazelle]

To be frank... It's a jumbled mess, that no one can understand what is happening.

[maiden wadi]

@naive dagger Setting it on tick is usually the easiest or most game secure method. You could put the camera on a spring arm, detach that from the character on beginplay and have the character's tick set the spring arm to the correct point on line along the X axis. This would move it along the X axis and also give you wall collision which I think you wanted based on the yellow square thing.

[timber cloak]

possible, i feel like a failure when i can't figure that simple logic, even after few days.

now gotta go back to practice next level on using this knowledge

thanks again

[naive dagger]

@maiden wadi If it doesn't bother you, could you show by example? I understood you, but visually, I still don't understand how to implement it

[maiden wadi]

Do you need to contain the camera within walls? Like will there be walls behind the camera that you need to keep it within?

[naive dagger]

@maiden wadi no, there are no walls, my cameras will switch depending on the position of the player in the world

[maiden wadi]

What distance do you want it to remain away from the player then?

[maiden wadi]

@naive dagger What Y value is that camera at, at the moment?

Y and Z actually.

[naive dagger]

@maiden wadi Y 968, Z 229

[maiden wadi]

I think I'm overthinking this. You can probably just set the camera's world location to it's own location for Z and Y and then the player's X location.

@naive dagger What class are you moving the camera in? Is this level blueprint, or the character class?

[naive dagger]

Level blueprint

[maiden wadi]

Try this then. Semi certain it'll work.

[dawn gazelle]

Looks good to me.

[marble nova]

trying to follow a tutorial and i'm not really told how to get these nodes / what they are to set the values, any help for a newbie?

[dawn gazelle]

They are values stored in the BP Sun Position Actor.

Get your BP Sun Position Actor node, drag off of it and type set Hours and it should come up.

[marble nova]

ah ok, thanks!

[trim matrix]

How can I check if a widget blueprint already is constructed?

[dawn gazelle]

Can you do an IsValid check on the "Uh" Audio component? before SetSound?

[weak kindle]

@dawn gazelle l do it

but l always do notbaid

[odd ember]

use the IsValid boolean with a branch, the macro has buggy cases where it doesn't work, just FYI

[dawn gazelle]

Can you clarify, is it not valid?

[weak kindle]

it is notvalid

[dawn gazelle]

Is that audio component on the widget itself?

[weak kindle]

yes

l want when my player press the button from wifget play the sound

basic l want play it with my video

[dawn gazelle]

Can't do that. Widgets aren't similar to actors and can't have audio components attached to them.

[weak kindle]

how can l have a mefia player and when player pressthe button play the video with audio

that is what l ahve try

3 hours now

[dawn gazelle]

Is this audio something the player should hear as if it is in the world, or can it just play back like it follows the player?

[weak kindle]

follow the player

[dawn gazelle]

You can just do play sound 2D

[weak kindle]

can stop that sound whenever l like?

[odd ember]

use spawn sound cue if you want to stop it

spawn sound 2d

[robust cliff]

is it always best to use interfaces vs casting?

[odd ember]

it is rarely better to use interfaces

in fact interfaces aren't really useful until you have multiple hierarchies

[weak kindle]

it works ty

can l sstop and media
?

[dawn gazelle]

The spawn creates a reference for you that you can do things with.

[weak kindle]

realy l thank u guys so much

sound works perfectly now

can l stop and video?

l guees l can if l change variables on mediaplayer

Where can I use nodes from Animation Blueprint Library? For example, this node does not appear in any blueprint editor for me to create https://docs.unrealengine.com/en-US/BlueprintAPI/AnimationBlueprintLibrary/Pose/GetBonePosesforFrame/index.html

looks like its only accessible in editor utility blueprint

[dawn gazelle]

AnimationThumbnailSkeletalMeshActor has that node available.

@dawn gazelle can l create my own animation with unreal engine?

[open crypt]

is there a blueprint equivalent of "bNetStartup" for seeing if an actor was loading from the map versus BP?

[vivid merlin]

I am attempting to create a line trace between two actors (Source and Target) with the line trace function in the Source actor BP. When I try to get to location of the Target by creating a function that :Cast To Target, Get Actor (Target) Location, Return Vector (Location) Node.

It doesnt work, and line traces somewhere else

Is there a way that works for line tracing between two non-player movable objects?

[royal rain]

so is anyone free rn, ive been wanting to fix a few things with a small game ive been working on, I want to use the ball rolling starter for unreal enigne as a base but there is a few problems with it

i want to use the ball roller to make a sort of racing game, but the controls are too loose still, i know theres the touge and the left and right turning but idk if theres anything else i can cahnge

[knotty quail]

Hello

What's the best way to handle switching between different animation states like holding a gun/vs not holding a gun

This is my animgraph now

all un-armed root motion animations

[maiden wadi]

@knotty quail I don't know the best way, but I have separate statemachines based on what kind of weapon the character is holding and I switch on those.

[past girder]

hi, i got a problem working on a climbing system but when i made a forward trace its backwards instead

[royal rain]

so ive kinda gotten controlls with the ball im comfortable with i might tinker with more but i want the ball camera to move and turn somehow so i can see where im going, ive looked up some solutions but they arent working

[tight schooner]

@trim matrix dunno what you're up to, but I'll just say a cast is essentially a check — it's asking whether the provided object reference (e.g. a reference to an actor in your game world) is of a certain class. If it is, the Cast node transforms the provided object reference into a class specific one.

It can't create a reference out of thin air, cuz it wouldn't refer to anything

You gotta give it something to check

If you're doing a collision or overlap check, maybe Other Actor is what you're trying to cast to? Dunno.

Well, if the variable exists on the parent class, you can cast to the parent and use the parent class as an "interface" to the children

As opposed to casting to every child BP specifically. I'm just speaking generically here

[past girder]

Can you help me to?

[tight schooner]

You have to show your BP script

[past girder]

Its supposed to be a forward trace but its backwards

[tight schooner]

oic. Uhh... A forward vector just goes from 0 to 1, but your trace wants world space coordinates

So you have to add your actor location to the forward vector

The usual setup is... (forward vector × something) + actor location

= endpoint

[past girder]

how?

[odd ember]

he told you how

[silent imp]

how do i communicate between a blueprint and a blueprint created with Spawn Actor of Class?

(I have a custom event in the actor i'm "cloning" that i'm trying to fire)

[winter garnet]

Hey guys. Having a hard time to call this Node:

https://docs.unrealengine.com/en-US/BlueprintAPI/AnimationBlueprintLibrary/AnimationNotifies/GetAnimNotifyEve-/index.html

I don't think it's being exposed to Blueprints somehow?

Ideas?

Even when I create a structure for the given input, Unreal isn't suggesting me given function:

[woven wing]

You probably want to have a locomotion state machine, and then an upper body state machine, which contains animations for specific weapons. You can then use a Layered Blend Per Bone to overwrite the upper body of the character with the Weapon graph.

This lets you do things like jump and shoot at the same time.

[knotty quail]

@maiden wadi @woven wing Thanks guys

[woven wing]

@winter garnet - You're almost certainly not using that right. The function returns the trigger time of a specific notify event.

[knotty quail]

This is currently how i am attempting it. Adding in different blend trees for each state. I will see how this goes and then if it goes poorly. try what you said

[woven wing]

@winter garnet - So you'd need to get a notify event you were interested in, and then use the function to get the trigger time.

[knotty quail]

I don't know if anyone knows much about root motion here, but I'm having an issue where my start and stop animations jitter and loop endlessly

[mortal nacelle]

Am I correct that a blueprint event cannot be called while a previous call is in a wait delay from a Delay node?

I am having my GameMode listen for character death events and clean up their bodies after a delay. But I notice if two actors die near the same time, only one gets cleaned up

[woven wing]

@mortal nacelle - I wouldn't use Delay for that, or have the GameMode do it. Consider having the character delete itself after they die, and, if necessary, inform the GameMode.

[mortal nacelle]

yeah, im realizing that may be better

but im wondering if this is the root cause of the issue im seeing, just so I can understand blueprints better

is it the case that an event currently waiting on a delay node would not be able to get executed again if called?

[woven wing]

Hmm, no I think Delay should handle being called multiple times in succession.

This surprises me, as I would have expected it to fail.

But I tested with this, and it did print:

If Delay were constantly being reset, we would expect this arrangement to never print.

But it does.

[winter garnet]

Hey! How do I get this notify event?

[woven wing]

Ah! I know what the problem is.

You're probably passing your Character To Be Deleted to the event right?

[winter garnet]

Also, these wires are dope! How did you get them? 😮

[woven wing]

As an argument?

@winter garnet - Here:

https://www.unrealengine.com/marketplace/en-US/product/electronic-nodes

I recommend them. They make blueprints a lot easier to read.

[knotty quail]

yea i think im gonna need to mask out the upper body somehow so i can apply animations just to that

because the way im trying to do it is just fucking everything up

[woven wing]

@knotty quail - Layered Blend Per Bone

[knotty quail]

thanks

ill write that down for later

[winter garnet]

Awesome, Jack. Any ideas whether this plug-in works with BlueprintAssistant?

[woven wing]

I don't. Not sure what Blueprint Assistant is.

[mortal nacelle]

@woven wing yeah, I have one parameter for the actor to delete in the event delegate declaration

[woven wing]

So that's what's going out of scope.

[mortal nacelle]

DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FOnDeathDelegate, AMOBACharacterBase*, DeadCharacter);

[woven wing]

The arguments you get through your Event are guaranteed only for the frame in which the event is called.

[mortal nacelle]

oh hmm, I see

so if this is called twice in the span of 0.1 second, then when it hits DestroyActor its going to be both pointing to the same actor (second one to die)?

[woven wing]

Yeah.

[mortal nacelle]

thanks, that makes sense

i guess I could store a list with the actor + timestamp on the frame I get it, and after the delay look through the list for any actors over the delay length to clean them up

but honestly its probably better to just do it in the character

like you said

I still want to control the execution of cleanup at a higher level, since player characters may be revived but NPCs never are. but I can create a custom Cleanup() event on the character to run the delay, and just call it from a higher level how I want.

[woven wing]

Or you could have Players and NPCs just have different functionality when they die.

[tight schooner]

@mortal nacelle try "Set Lifespan" node for delayed destroy, FYI

[woven wing]

I tend to go crazy for components, so I'd have the main class have an OnDied event, and then have components on them that react to the event.

So an enemy would have a CleanUpOnDying component.

[mortal nacelle]

@tight schooner nice. is this non blocking??

[woven wing]

And Players would have CanBeRevivedOnDeath component.

[tight schooner]

@mortal nacelle I think the actor class has this countdown-to-death functionality built in...

[mortal nacelle]

thats awesome

thanks

[tight schooner]

I think the timer can be cleared if you set lifespan to 0

[mortal nacelle]

running these delay tasks is pretty limiting

in terms of where it can go

[tight schooner]

in any case the timer runs inside the target actor rather than the BP externally "managing" it

[mortal nacelle]

yeah, so its non blocking for the blueprint execution. that is really what im looking for

👍

@tight schooner that worked like a charm to fix my bug!

[tight schooner]

my current project has music-synchronized gameplay so I sometimes have scenarios similar to yours

and there are times when I collect things into an array

and then process that array at some delayed time

so yeah that's another approach to the problem depending on how you want it to work

[woven kelp]

are these two nodes functionally identical?

[woven wing]

So the animation blueprint library functions only exist as part of Blueprint Utilities.

You can get the animation notifies from a sequence, and then call GetAnimNotifyEventTrigger on them to get their trigger times.

It's very likely that what you're trying to do should be done by other means.

[jovial elm]

is there a way to generate a dynamic collision box?

[tough halo]

Hello.. I am trying to make an automatic rifle in ue4. I am using set timer by event and then letting it fire a bullet every "firerate" seconds

for now I have fire rate at 1 second for debugging

the timer waits one second before triggering the shooting event

[royal rain]

can someone help me with getting a camera to follow around an object better

[tight schooner]

@jovial elm yeah, you can add a collision component with BP

[royal rain]

its the ball object from the pre fab

[tough halo]

does the Inital start delay not do what I think it does?

[jovial elm]

@tight schooner can you make it generate continuously and expand in size based on player input?

or would you need to do cpp for that

[tough halo]

so a timer always waits for the given time before firing the event? so the correct way to set this up is to spawn the bullet, then start the timer to let it fire the next bullet?

sorry if these are basic questions, but I'm confused since it seems to me that the inital start delay would control when the event is first triggered

[odd ember]

the fire rate is the rate between bullets

if that's what you're asking

[odd ember]

you can. box extents and scale work as normal

you can base that on player input if you want

[tough halo]

the timer will fire the event at the time interval that I have set to fire rate in my bp. My question is when is the first time the timer fires the event. Should it do it immediatly given that the inital delay is 0, or does it always wait for time?

[jovial elm]

awesome ty ill look into it then

[odd ember]

if there's no delay then how will it wait?

[tough halo]

the "Set timer by Event" node has 2 inputs. One that is Time, one is inital start delay. Time is 1 second, inital start delay is 0

[odd ember]

consider there's a reason they added an initial start delay parameter

[tough halo]

I'm expecting it to fire immediatly, and then wait 1 second before subsequent firings

[royal rain]

ive tried a bunch of ways to get the camera to work on the ball roller from the internet but they weren't that good, does anyone have any suggestions

[odd ember]

it'll fire, wait out the delay

and fire again

unless you have an initial delay set

[tough halo]

but it doesnt behave that way.. when I create the timer it waits for one second before triggering the event

I simplified my blueprint abit

[odd ember]

you can create it and immediately pause it then

then use your fire button to unpause/pause

[tough halo]

"Set timer" is printed when I press the fire button, one second later "Actually shooting" is printed

[odd ember]

I gave you a method

you can try

what version of UE are you using?

[tough halo]

4.26

to be clear, what I want is that it will fire immediatly for the first shot

so primary action pressed fires 1 bullet, then waits 1 second before the next bullet is fired

primary action pressed is right mousebutton. I had a "Clear and invalidate timer" node connected to button released

[odd ember]

did you see that I mentioned pause and unpause you could try?

[tough halo]

can my problem be that the timer still exists in memory so when I set it again it already exists and then waits

yeah, pausing it wont really help me tho.. I'm trying to understand why it doesnt behave the way I expect it to behave

[odd ember]

why won't it help you

it should solve your issue

[tough halo]

the issue is that it waits, when I want it to not wait

if I pause it should just wait longer

I dont see how that will solve anything

[odd ember]

have you tried it?

[tough halo]

thank you for trying to help tho, it's much appreciated. Maybe I misunderstand what you mean, but I dont see how pausing will help anything

[odd ember]

I think you're making the mistake of not trying new stuff when your current setup is broken

[tough halo]

if I pause it at time 0, and then unpause it it will still wait "Time" before firing again right?

[odd ember]

try it and find out

[autumn plover]

Anyone know how to get specific player controller from pawn, or from server if impossible on pawn? Trying to get a pawn on death. I find it hard to get a specific player controller when no input is pressed.

[autumn plover]

whoa... hope this works...

[dawn gazelle]

That needs to be done on server, player controllers are not shared between clients.

[autumn plover]

By server do you mean that in pawn bp make custom server event?

[dawn gazelle]

yep

[dawn gazelle]

You should get a reference to whatever pawn it is that you're trying to get the controller of. So if you're running something from the Pawn's BP, you can just use a reference to self.

[tough halo]

@odd ember Thank you, that explains it

also, the inital start delay is weird as fuck 😄

[timber cloak]

need people to correct my stupid brain please

https://imgur.com/a/RkRZUNv

what i am trying to do ^, doesn't matter which step comes 1st

https://imgur.com/a/dDnsJgp

https://imgur.com/a/Z4BBW9C

which one of the last 2 screen shots are correct or both are wrong?

ignore 2nd step, since that is easily be done. Only 1st step is what i am trying to do now

[odd ember]

I'll be the first to admit I have no clue what you're trying to do

[woven wing]

Yeah me too.

I am confused.

[odd ember]

I can't imagine you trying to actually explain this game to a player down the line

[timber cloak]

no, this is not a game

it's a practice

i am trying to to give Strings to Enum value

the Enum value is Exposed on Spawn, and assigned to each player already

now, how to get* each Enum to get strings

[woven wing]

You probably want a map.

[timber cloak]

Map is not replicated

[woven wing]

Wait what?

[timber cloak]

struct can do this? but then again struct isn't really for random, right?

[woven wing]

What?

[timber cloak]

it is not replicated...

[woven wing]

In your explanation, you never mention replication or randomness.

[timber cloak]

map cannot be replicated*

[tough halo]

how many fruits in your box?

[woven wing]

What?

[timber cloak]

10 fruits

[tough halo]

how many players do you have?

[timber cloak]

i mentioned "already assigned to each player already"

[tough halo]

hahah

[timber cloak]

10 fruits 5 players, easier for 2nd fruits to be given later on

[tough halo]

you only have one loop, when you get to the 6th fruit you are getting a player from your player array anymore

[timber cloak]

should i ask this to multiplayer channel?

[tough halo]

unless they are in there more than once

[timber cloak]

2nd fruits can be done with simple loop logic

[odd ember]

I think nobody really understands what you're trying to do

[tough halo]

I think it will be difficult to get help since your question is so confusing

[timber cloak]

i explained, which part confused?

[odd ember]

except dig yourself deeper into this rabbit hole of epic proportions

[timber cloak]

I said Enum is Exposed on Spawn, and is already assigned to all players

[woven wing]

So on spawn, a character is assigned a Class. You then want to assign them items, randomly, based on their class?

From a list?

[timber cloak]

Now, example "painter" enum in 2 players, they 2 (painter enum) get same 1st fruits

and as i said, ignore 2nd step/2nd fruits

fruit box is a String Array

[odd ember]

I think you're missing the logical thread here. like what does a painter have to do with fruit etc.

[timber cloak]

and already has 10 fruit variable in fruit box array

nothing... enum is just a name...

like i said this is NOT a GAME. This is to practice

[woven wing]

I'm also confused as to why "Role Name" is an enum.

[timber cloak]

Don't assume it is a game or else you get confused

[woven wing]

Because one thing enums aren't is Names.

[odd ember]

well it's all the same if we can't understand what you're trying to do

[timber cloak]

Role name = Painter, Dentist, Salesman, Chef etc (this is Enum)

[odd ember]

game or no game

[woven wing]

It is much easier to understand what someone is trying to do if we can get the metaphor.

[timber cloak]

fruit box (array of strings, containing Apple, Banana, Papaya, Mango etc)

1st fruit (string variable in thirdpersoncharacter class BP, is empty)

2nd fruit/2nd step = ignore

[woven wing]

What?

[timber cloak]

enum is just a name/type/category

etc.

[tough halo]

he has a variable named 1st fruit in the player class

[woven wing]

OK, you have two lists:

• fruit names
• players

You want to assign a fruit to a player, right?

So if the first element of Fruit Names is "Apple" you want Player_1 to get "Apple"?

[timber cloak]

yes, all fruits data stored in the "fruit box" array

the "1st fruit" is string variable, empty and it is in "thirdpersoncharacter BP class"

"role name" is an enum (painter, chef, dentist etc)

is it still confusing?

[woven wing]

Yes.

[odd ember]

yes

[woven wing]

Very!

[timber cloak]

i will delete the paint editting

[odd ember]

what is the logic between the role and the fruits

I think that's my biggest question

[woven wing]

Yeah - walk through this with us. You have your list of fruit names, and you have your list of players.

What do you want to happen to the players?

Do you want the players to get something from the list?

[tough halo]

every painter should get an apple and every chef should get a banana

I think

[woven wing]

I thought that too at first, but apparently not?

[timber cloak]

no, they get random fruits from the fruit box array

[odd ember]

okay

but why

[woven wing]

So... does the fruit make you a chef?

Like if you get given an apple, now you're a chef?

[timber cloak]

no, it does not make you anything

[odd ember]

if you get a mango do you become a dentist?

[woven wing]

OK, so how does the class matter then?

[timber cloak]

nope, fruit is just given, that's all

[woven wing]

Then why... did you mention the classes?

[odd ember]

so the roles mean nothing in relation to the fruit

[woven wing]

Why are the classes in your code?

[timber cloak]

roles* is also randomly assigned, that's all. No power no skill etc.

[woven wing]

So anyone, regardless of class, can be assigned any fruit?

[timber cloak]

yes

[woven wing]

OK.

[timber cloak]

yes

[woven wing]

So why did you mention the classes?

Are the classes relevant at all?

(what is happening?)

[timber cloak]

not relevant

[woven wing]

Aaaa

[timber cloak]

don't think of it as a game where people gain power/ability because they get a job/role

think of it as if you are doing homework

[odd ember]

well no apparently they don't even gain fruit

[timber cloak]

problem solving and learning

[woven wing]

So, to summarize:

• you have a list of fruit
• you have a list of actors

You want to assign one fruit to each actor?

Right?

[timber cloak]

to each "enum", rather than actor

[woven wing]

What?

That's not what you've just been saying!!

[timber cloak]

same enum will get same fruits

[odd ember]

so all chefs DO get bananas

[woven wing]

Hehehehahahaha

[timber cloak]

yes, if a chef get BANANA, all chef gets banna. If chef gets Apple, all chef gets Apple

enum = a group of people etc.

[odd ember]

so there is a relation between the fruit and roles

lmao

[woven wing]

Whatever the outcome of this conversation, the skill you need to work on is not blueprints. It's communication.

[tough halo]

I'm frank to uuutps charlie

I'm guessing english isent his first language

[timber cloak]

i am so bad at programming and communication sigh

[odd ember]

just work on communication first

if you can't get your ideas across

then nobody can help you

it is by far the most important skill in game dev

in fact there's a role in game dev solely dedicated to it

[timber cloak]

can tell, i suck at explaining to people daily

[odd ember]

anyway

you should use a map

[woven wing]

OK, so let's try this again:

• we have a list of fruit
• we have an enum of types of classes
• we have actors who have already been assigned a class

We want to go through the fruit, and assign each fruit to a class.
Then we want to go through the actors, and, if their class matches, we want to give them a fruit of that type.

Is this correct?

[odd ember]

the map doesn't need replication

because you just need to check it on the server

[timber cloak]

correctt

[odd ember]

and it should spit out a replicated value

[woven wing]

So if we assign 'Apple' to 'Chef' we want to go through all our actors and say "Are you a chef? If so, have an apple."

Right?

[timber cloak]

yes, but fruits are given randomly.

[odd ember]

that's fine

it's not an issue

[woven wing]

Are they given to actors randomly, or are they given to classes randomly?

Or both?

[timber cloak]

put in server it is replicated itsel?

[odd ember]

classes

[woven wing]

Because this is a two step process.

[timber cloak]

given to classes randomly.

[odd ember]

I'm starting to see the light

[woven wing]

OK.

Me too.

[odd ember]

for better or worse

but @woven wing's map suggestion was correct

it just needs to be implemented correctly

your game mode in this case will be your manager

[timber cloak]

there is no relation with role and fruit. Nothing is fixed. All randoms

[odd ember]

there is a relation

[timber cloak]

basically you keep randoming nonstop

[odd ember]

the relation is that all roles of the same type get the same fruit

that is still a relation

we spent 15 mins trying to figure that out

[stable lintel]

can someone help me with the attach actor to actor node

[stable lintel]

it's killing me

[timber cloak]

yes, same type of roles get same fruits

but fruits are given randomly

[odd ember]

yes

that's fine

it has no bearing on the relation

look at the above graph

[timber cloak]

yea i will try Datura's way

[woven wing]

Sure, what's your trouble?

[stable lintel]

alright may be a newbie problem

i have no idea whatsoever how to use it

but i want to attach a gun to the hand socket

[woven wing]

Ewkay.

Do you have a bone or socket in your skeleton for your gun?

[stable lintel]

yes

[woven wing]

Is your gun a separate actor from your character?

And is it being spawned correctly?

[stable lintel]

yup

in the map

i just don't know how to use the node

[woven wing]

Yep

that's how you use it.

It's pretty self explanatory.

[stable lintel]

OH god

i was using the component on the gun instead of the character

such a dumb mistake

[tough halo]

@timber cloak did you understand Daturas example?

[timber cloak]

yes, i understood he shuffle it to make it random. The enum element then is added into the map, the map gets fruit arrays. Straight forward though

the only thing is, i never know how to pass Map's info into ThirdPersonCharacter

[odd ember]

you dont

[dawn gazelle]

You shouldn't need to.

You can pass the key (your job enum) and the value (the fruit) into the ThirdPersonCharacter when you're spawning them.

[odd ember]

any time you want a player to get fruit, they will give the gamemode their role, and the gamemode will tell them what fruit they can have

or that, assuming they spawn with the fruit

at this point I'm not sure

[timber cloak]

but how do you check which is the fruit they get from the map data?

i have 2 string variables in my ThirdPersonCHaracter, called "1st fruit", and "2nd fruit". Both are string variable

[dawn gazelle]

You assign them a job first. However you do that is up to you, whether randomly or by their choice, however you want it to do it.

[timber cloak]

i assigned already

[odd ember]

cool

[tough halo]

loop your players, get the role, use it to get the fruit value from the map, and assign to the player

[timber cloak]

I assigned Enum already. Have 2 string variables made inside ThirdPersonCharacter class

[odd ember]

so now you can use GetGameMode and cast it

[timber cloak]

no, role is made and assigned*.

[odd ember]

then use the map inside of your game mode with your role and the Find function of the map

[timber cloak]

ok done that long ago

[tough halo]

yeah, but you use it to get the correct fruit from the map that was made with daturas example

[odd ember]

so again, for the map, you put in role and out comes fruit

monkeys are celebrating across the globe

[timber cloak]

i am trying to digest. Wait, so the string variable in my ThirdPersonCharacter BP is not needed to store the fruit value from the fruit array (in GameMode)?

[odd ember]

not really no

you could replace it with a boolean of HasReceivedFruit

[tough halo]

You can save it there to have easy access, or you can keep the map and get the fruit whenever you need it from the map

[timber cloak]

if i would like to save it for easy access, how though?

[woven wing]

The one limitation is that you can only assign one fruit per role to the map.

So if you had say, 100 fruits and 5 roles, you would end up with a map of 5 roles to 5 fruits.

[timber cloak]

correct

[woven wing]

Or... I suppose a maximum of 5 roles to 5 fruits.

You could roll really weird and somehow end up with say 1 role assigned fruits 100 times.

But that is Unlikely.

(it is, however, common enough that the utility of this scenario, already precariously bizarre to start with, becomes dubious in the extreme)

[timber cloak]

even 100 players with Chef enum, they only get 1 same fruit.

[odd ember]

yes

they fought hard for that fruit

now let them have it

[timber cloak]

yup, that's what i am trying to learn about. Problem solving

[tough halo]

with daturas example each job gets a unique fruit, given that there is enough fruit, and no fruit is repeated in the fruit array

[woven wing]

Ah, that's true.

My bad.

But if the fruit array is longer than the jobs array, than some fruit will be 'lost'.

By being assigned over.

And if the jobs array is longer than the fruits array, then some jobs will get no fruit.

[odd ember]

you could have the array give out more fruit if more roles are in play

by comparing the arrays

[tough halo]

@timber cloak you want to loop through your players, then pass their role into the job-fruit map which will spit out the fruit for the given role, then convert it to string and set it in "1st fuit" in your player

[odd ember]

I think the big question is now

[timber cloak]

ok i am trying.

[odd ember]

what is "2nd fruit"

[woven wing]

what is "2nd fruit"
Says Cranz, uncorking the next can of worms.

[tough halo]

lets get the first one before we start with the second

[odd ember]

jumping into the rabbit hole no parachute

[timber cloak]

2nd fruit is the different fruit, regardless of enums, everyone gets it differently. Basically the generic for loop logic.

[odd ember]

you can handle that by having another map for the 2nd fruit then

[timber cloak]

so after the 1st fruit from the map, i remove index on the fruit array used for the map

[tough halo]

I came here to get help with my specific problem, but I'm glad I came, this is hilarious

[odd ember]

oh absolutely

[tough halo]

you dont have to do anything to the map

the map contains keys and values

[timber cloak]

wait i am doing the 1st one first

[tough halo]

basically it maps a job to a fruit

thats why it's called a map

it's a list that has painter=mango,chef=banana,hitman=orange

and so on

[timber cloak]

uh i see now. It is clearer. Thanks for the details. I never used map

[tough halo]

I have another question guys.. how are things working behind the scenes in a blueprint

if I press my secondary action I make a timer

[odd ember]

as we've just found out

[tough halo]

so if I press it twice I should get 2 timers right

[odd ember]

the timer is used even on the initial run

[tough halo]

or will there only be one timer since it's the same event

lets assume it's 2

now I have the timer return value hooked into clear and invalidate

[odd ember]

test it

[tough halo]

thats connected to another event

[odd ember]

you may have found a way to produce a dangling pointer

[tough halo]

I did test it, only one timer seems to be produced

but the question still stands

how does the blueprint stuff handle this

it's 2 separate events

I feel like I shouldnt be allowed to make a connection between

them

[odd ember]

you shouldn't

[woven wing]

Timers are weird.

[odd ember]

but the variable persists

for as long as the timer persists

I'd save it as a variable

and use calls on that variable

[tough halo]

yeah, thats why I have this question.. I made a variable in my "real" code

[odd ember]

it is saved by ref so you're technically just saving a pointer

[tough halo]

but if I start another timer, I overwrite the variable

[woven wing]

Yeah, the return values of a function are, like arguments, only valid immediately after they've been called.

[tough halo]

that code works tho

[woven wing]

If you want to keep them around, you have to store them yourself.

[tough halo]

even if it only makes one timer

[woven wing]

Sure, but that's kind of 'undefined behavior'.

It works, but it's fragile as hell.

[tough halo]

yeah I feel like there is a hole here

I like to understand what happens tho

[odd ember]

well like I said you may have found a way to produce a dangling pointer

try with the variable

[tough halo]

what are the blueprints anyway? do they get translated to cpp?

[odd ember]

they are wrappers for cpp yes

[woven wing]

No, they run in a virtual machine.

[odd ember]

well

[woven wing]

They call c++ functions.

But blueprint logic itself is a virtual machine.

[tough halo]

interesting

[odd ember]

they are technically very foiled in cpp, the VM is probably just removing their shell

otherwise stuff like nativization wouldn't exist

[tough halo]

so I assume it will be slower than if I made the same stuff in cpp?

[odd ember]

about 10x slower yes

[woven wing]

Yeah, but there aren't actually that many places where that speed increase is really gonna matter that much.

Your architecture is a lot more important than your language.

You can write really slow, really crap c++.

[odd ember]

where's that allar video

https://www.youtube.com/watch?v=flEtQBPtBTc

[woven wing]

Yep

[tough halo]

haha

[odd ember]

Allar used to be a mod in here, not sure he's still one

[still sigil]

So does anyone know how to go about making a smooth music transition system? Like the level loads, and it starts playing an intro track, which starts up the level's music, then after that intro track ends, it smoothly goes into the "Main Loop" portion of the level music.

One would assume that all you would need to do to get this to work is to set a timer or a delay or something to the exact length of the intro track, so that when the delay ends, it then immediately starts playing the main loop. But I've done this, and it's extremely inconsistent. The main loop either plays a little bit after the intro track has ended, so there's like half a second of dead air, OR it'll play too early, and overlap with the intro track a bit before it truly finishes. SOMETIMES it'll play at the right time, but it's pretty rare.

I've tried a few different methods of going about this, but they all seem to give the same results. There doesn't seem to be any tutorials on the subject either on how to do this properly, so I'm kinda in the dark here.

[tight schooner]

@still sigil Timesynth. It's a little janky but it does work. I think 4.26 also added some similar stuff ("Quartz"?) but I haven't looked into it

Timing music-sync'ed audio with BP events sucks... I know cuz I've done it

If you have to do it with BP events, then you need to design your audio with fadeouts

so that the new clip can overlap the outgoing one a little

and prevent dead air

[still sigil]

It does! And it's weird, cause you'd think it wouldn't be. If you have access to all the numbers you need right there, you would assume that's all you'd need to time it right. But apparently not. 😛

[tight schooner]

BP only runs on each game frame

so it can't time things in between frames

That's the fundamental issue that Timesynth seeks to solve

If you have further questions about audio specifically, the #audio channel is good cuz Epic developers are there

Timesynth and Quartz are things that Dannthr worked on, iirc

[still sigil]

I'll have a looksie! Gotta update first though. The project I'm trying to get this to work on is running on an older version of UE4, so timesynth ain't even on there. Woops. 😛

[rough blade]

I am working on a project that requires a player to be locked to a craft. To do this every tic i set their location and rotation to that of the craft. To move around the craft I have offsets that change according to input. I figured out movement but am stuck on looking around. In essence when the player wants to change their yaw (look left/right), the engine by default uses their world yaw when I need it to change with their yaw in relation to the craft. I currently store their desired yaw as a float but am unsure of how to convert this into a yaw relative to their craft. Help?

[bitter schooner]

Any idea why newly created soft object references in 4.26 are not setable in the details panel anymore?

[timber cloak]

i am really really too stupid to figure out how to set the 1st fruit variable.

even after looking at documentations

https://imgur.com/a/HTCfQGN

https://imgur.com/a/hF00p34

are both versions wrong? please correct me

[dawn gazelle]

The game mode begin play only fires once on the server, and it runs before you have everyone in the game. How you have it set up now it cannot find any players in the game, so no players would be assigned anything.

[timber cloak]

https://imgur.com/a/oVeD93h

i set it up in override function

so it will spawn straight away

[dawn gazelle]

You're still not hearing what I'm saying.

This here will not get anything

So when you're running this

it's empty, so nothing happens in this loop

[timber cloak]

uh i see

my bad, misread you

let me change to OnPostLogin

[dawn gazelle]

If you do, do not loop through the list of all characters each time someone logs in.

[timber cloak]

um, so what do you suggest if not loop through the list of all characters?

sorry, i am too stupid to figure out

[dawn gazelle]

Ask yourself this - why do you need to iterate through all possible players when a new player is joining the game?

[timber cloak]

the other guy was suggesting to loop, which was why i tried that method

to give them the "1st fruit" string variable?

[dawn gazelle]

If player 1 joins the game, and he gets assigned the variable, does he need to get it assigned again when player 2 joins?

[timber cloak]

Nope. I see now

[dawn gazelle]

You should loop through an array of players if you need to do something to all of them, which you really shouldn't need to do when a player is joining a game normally.

You're only interested in setting up the new player that is joining with values.

[timber cloak]

but then this is just get the String from the map and Set it into the "1st fruit" string variable only, right?

i see

[dawn gazelle]

On the OnPostLogin event is when you should be assigning that player their job, their first fruit, and even their second fruit.

[timber cloak]

the loop is not assigning the Map value 2nd time, correct?

[dawn gazelle]

You shouldn't be looping at all really.

[timber cloak]

but instead, it is getting the value of the Map, right?

uh okay

https://imgur.com/a/HAksEnx

correct? please correct me on anything wrong

wait, the index, how would one do in this case?

it's 0 index

i mean the "get" node

[dawn gazelle]

Since your fruit that you want to give the player is based on their job, how are jobs assigned? Are they distributed randomly? Are you just assigning them out in order from an array somewhere?

[timber cloak]

the jobs are distributed randomly as shown earlier

wait

https://imgur.com/a/oVeD93h

The "Roll the Dice" function

[dawn gazelle]

When is this function called and what does it contain?

[timber cloak]

hold on

https://imgur.com/a/9qvy1ud

this is function

i print out the widget from the ThirdPersonCharacter for these enums in there

have enum done as well as the "2nd fruits" string.

only left the 1st fruit

was it wrong somewhere to set the "1st fruit" string in the screenshot? Please correct me

[dawn gazelle]

Where are you calling the "Spawn Default Pawn For" function?

[timber cloak]

at "Override" in function list

on your <<< left side

it's there in default

click "Override" the list will show you

[dawn gazelle]

ok, do you have your default pawn set to "None"?

[timber cloak]

yup i tried that earlier, same result

getting the string from "Values" node, is correct, right?

or is it wrong?

[dark crow]

Is that a never ending While Loop?

[timber cloak]

i re-read from your message few hours ago, that's what i did

it ends

otherwise it will print out "infinite loop"

i am really really too stupid to figure anything out T_T

[dark crow]

I would never leave the loop condition always to true no matter what

It's probably not saying it's an infinite loop cause in theory that would be one way to use it if you want to run something during all game

Even if there's timers for that

[dawn gazelle]

Disconnect everything from the Begin Play on your game mode. Connect only the Shuffle for your fruit array.

Update your Spawn Default Pawn For to look like this.

[dark crow]

Can't you like plug the Branch condition in the Loop instead?

I feel like it's looping and just giving you False in the Branch After

[timber cloak]

done, no proper results

[timber cloak]

which? The While Loop node to be removed?

then the decrement/increment node won't be moving

let me try

yup, you can't remove the While Loop, or else the Enum won't be working correctly.

[dark crow]

i mean like

[pine trellis]

I need to send someone my project but its 32 GB large, is there a way to just send the basics? I need to just basically send 1 map and everything that map uses

[dark crow]

Completed would be the same as False in the Branch

And the loop would stop

But Completed instead runs once only, if you keep it always looping, the Branch False would always run cause the Loop never ends

While (Condition == True)

It loops

[dawn gazelle]

Not even sure what this is for..

[timber cloak]

yup, i just removed as per your instruction, cannot too. I even moved the While Loop in front as well, same result. fail to work

[timber cloak]

these are integers to set the amount of "enum"

[dawn gazelle]

but why?

[timber cloak]

like I want 3 chef, so i make it 3 chef

[dawn gazelle]

ok

but then you do this with it

[timber cloak]

yup, it minus the amount back to 0

that's why you see the > and a zero

once it zero, the loop ends

[dawn gazelle]

No, it subtracts the value from the select - it's not going to store the value back in the variable (like New Var 2 or New Var 4, etc.)

[timber cloak]

that's why it is not infinite

correct, if i put 3 chef, it substracts all the chef to 0

hence it is working correctly as i wanted

[dawn gazelle]

so what happens when only 2 players join the game?

[timber cloak]

it gives all 3 chefs to 2 players

i tested all situations, it worked correctly

so how do i get the 1st fruit from the map, please?

i guess somewhere went wrong T_T?

[dark crow]

Wait

That loop is in a Function right?

Yeah

Are you sure it's not running only once for some reason?

Just one loop

[dawn gazelle]

It's only ever running once

Since he has the return node there.

[dark crow]

Yeah

I just realized

[dawn gazelle]

And it's always going to be > 0

[dark crow]

The return ends it

[dawn gazelle]

But, "he tested it, and it's working correctly".

Sorry, but I'm getting slightly annoyed.

[dark crow]

You would want a Macro for a Loop to work correctly

[timber cloak]

yup, i am not even sure of other results anymore. If i put the number lower like 3 chef and 2 painter. Then it's 6 players total, the 6th player gets nothing

unless the Branch's false comes with ++ increment node, 6th player can get the 2nd result

[dark crow]

Remember that functions with return flow once

Transfer your code to a Macro and use this

https://cdn.discordapp.com/attachments/221798862938046464/788611607273799710/unknown.png

[timber cloak]

this is basically i Override the default function that exists inside the engine

[dark crow]

Or you get infinite loop indeed

[timber cloak]

so make a macro and put that in that overriden function?

[dark crow]

Just transfer the entire code of that Function into a Macro that does the same thing

Basically just a copy and paste but it's stored in a Macro instead of Function

[timber cloak]

correct?

correct me if i am wrong

[dark crow]

Should be clear, just remember that Macros can't have Local Variables like Functions

[timber cloak]

no character loads up after using macro. Even it is "None" or "thirdpersoncharacter" in worldsetting

[timber cloak]

it worked for you?

is there something you changed?

[dawn gazelle]

Yes, but not the way you've done it. If you follow the last screenshots I've done it works. Just make sure your assigned job and fruit variables are set to replicated on the character.

[icy saddle]

Is there an equivalent of UWorld::ServerTravel in BP?

[timber cloak]

let me check and deleting the 2nd fruits for now

[royal rain]

i know my questions are very boring to answer but i have gone through an entire page of google search results to not get any help on my situation, i just want the camera to rotate with the ball, all the stuff ive googled is otu of date

[dark crow]

Execute Console Command

ServerTravel Level

[dark crow]

You mean the camera to follow the Ball rotation 1:1?

[dawn gazelle]

my roll the dice will randomly select a job, and then keep track of the jobs taken as well and reroll if there's more than what is required.

[royal rain]

idk i you know how the ball game pre fab has a locked camera, i want it so the camera can turn left and right when the ball turns left and right

and yeah not have it go ham when it bumbs into something

which i got once

[dark crow]

just Attach the camera to the ball?

[royal rain]

there is one

[dark crow]

And have it on Relative Rotation?

[royal rain]

its locked in the spring arm or something

[timber cloak]

i got results too but the thing is, only the first enum's will be able to print out result, the rest other enum will not print fruits (only blank)

uh let me see your screenshots first

[royal rain]

look it might seem really simple but ive been on and off of this all day I don't know where to start

[dark crow]

So lemme get it right a sec, you have ball, ball rotates, the camera follows the ball but doesn't rotate with it, you want the camera to rotate with it?

[royal rain]

yes, i got it to kinda work once really terriblely where it would shutter at any impact and it was at a bad angle

so like the ball is like a car

it would move in its direction

but its a ball

[dawn gazelle]

@timber cloak Sorry, one correction for the roll the dice function, it should be last index here, not length

[dark crow]

I mean, it can be done multiple ways, the most primitive one being attaching the Spring Arm to the ball, Rotation of Springarm to Relative then use the Inherit options in Camera Settings to X Y Z limiations

But depending on how your ball rotates the result can vary

[royal rain]

that might not work

becuase the balls rotation can be

special

maybe more like whenever the ball is sensed to turn left or right it moves the camera

there are many ways i saw it done on google but a lot were out of date

or i couldnt find what nodes

or it had things happen that werent good

[timber cloak]

wait, i am too slow

how do you make the job count variable? i was sure i could make it

[dark crow]

Well, in theory Direction is the Velocity

[dawn gazelle]

Make it a map of jobs to integers in the game mode.

[timber cloak]

something new, right?

[dawn gazelle]

A new variable, yes

[royal rain]

so idk what to do

[dark crow]

Well

There's a very stupid way for it to work based on the Velocity Axis

If you're working with a Pawn you can test it in this way

Very ugly, but will rotate towards the Velocity o the Z Axis aka Left and Right

[timber cloak]

could i see it, please? As of now i am only assuming another for loop job integer to job enum and lastly, add* to map?

[dark crow]

Not sure what system you're going it, but for a top down view this works even if it would need some polish

Like a smoothing of it, or it snaps

[dawn gazelle]

You can just have it set with default values.

[timber cloak]

i am trying to figure out why infinite loop is happening

[timber cloak]

also, this part i only can click the "+" once only

[royal rain]

sorry just looked at it

why is it ugly

also the set world rotation doesnt work with floats idk how to get it to accpect a float

[timber cloak]

how are you able to make 3 Map elements with the "+" icon?

[royal rain]

its not working @dark crow and it doesnt seem thats how the nodes work anymore

idk

[dark crow]

Right click on the Rotator and Break it

[timber cloak]

"Cannot add new to the map while a key with default value exist"

[royal rain]

i didnt know that was a thing

[dark crow]

Split

[timber cloak]

uh i solved it

your macro has infinite loop

[royal rain]

what do you mean by break rotator

nvm

i got it

[rapid token]

What is the best/easiest ways to make destruction physics?

[dark crow]

If you drag a rotator and search break from the pin it will break it

Same as Split but may be more pleasant to the eye

Instead if they receive inputs it's Make

Break Rotator / Make Rotator

For example

[royal rain]

im sorry that isnt going to work, kinda makes the controlls unplayable

i did it but like if i bumb into anything it breaks the game

[dark crow]

Yeah i dunno how you have it set up

So can't really give a good answer

[royal rain]

i have it set up right out of the box from the ball game pre fab

thats what i said, though i forget if i said it now

its been a long day

[dark crow]

Same here, kinda braindead and never actually tested the ball game pre fab myself

Lemme think of something

[royal rain]

ah

i did kinda get the ball game to control more smoothly though the controls where almost there and i was able to make it so it turns at a nice drift

might need to head to bed though its a busy day tommarrow

i hope it wont take as long tommarow to get some help

[dark crow]

Will try to help more tomorrow in case, need to get to bed myself too, destroyed my sleep schedule :'D

[timber cloak]

@dawn gazelle got it working, but do you happen to have your server's only screen not printing anything? The rest of screen worked, only server's screen prints blank

[dawn gazelle]

Seems like SpawnDefaultPawn doesn't call on listen server.

[timber cloak]

but earlier the one with original failed function manage to call server

but that function only worked for single enum, the rest enum is printing blanks

i think might as well not to use SpawnDefaultPawn?

also, been figuring out, how to set an amount for Enum using your function? The job count isn't really accurate in number when set in it

[timber cloak]

um, the enum and 2nd fruit is being called on listen server.

[hollow drift]

Hi folks, i have a math challenge:

I have to use addrelativerotation since the object has been turned with a script in its right place

problem is, that using add with an animation will add every gametick the current value from the timeline to the rotation. So if i set from 0 to 1 a increas to 1 value, it will add each game tick something like:

my value on 2 seconds is 0,1

is there some way to calculate such animation. some math concepts or so i could read about? Best practice? Anything then just trial and error for ethernity

[earnest tangle]

maybe you can save the current rotation before starting the timeline, and then use saved rotation + value from timeline with set rotation instead of add rotation

[hollow drift]

hmm i see

good idea

programmer problems be like: here is a easier solution instead of fixing something. Love it^^

[earnest tangle]

lol yeah that's how it often goes

[steady orbit]

Trying to great a click and drag movement system on X and Y for my top down game.
I'm using a basic pawn class and i have wasd working perfectly. Just cant get this to work?

[hollow drift]

@steady orbit it will be about that large at the end lol

and here are example scripts:

https://docs.unrealengine.com/en-US/AnimatingObjects/Paper2D/index.html

the answer.unrealengine should give you already a good idea how to start

if ended up understanding and reworking the whole code from scratch

[steady orbit]

Nah, i dont want to drag and drop items, i want to simply pan around my map by clicking and dragging anywhere.

[hollow drift]

basicly use a custom player controler

ah

[steady orbit]

Yeahhhh

[hollow drift]

well

make better question please^^

[steady orbit]

Im making a top down like Europa Universalis

[hollow drift]

why not use same principal but instead of picking up you just move camera?

[steady orbit]

I dont even know at this point

[hollow drift]

like just a character

[steady orbit]

Can i stream this to you in a call, it'll take 1 min

I wont waste your time

[hollow drift]

i can give a second thought shure

just be aware, i still have not done stuff with camera in my project

i wonder how to call it too, or just drop ...

lets try

[hollow cape]

a way to debug that would be to turn off the draw debug on the second trace, then add a debug of some kind off the false of the first branch, since that's where the failure is happening

you can do a draw debug line, sphere, whatever off the false, using the data that was used to create the first linetrace, so you can visualize exactly how it's failing

@swift pewter

how do you know. The only thing that would cause you not to see the trace, and not have it "fire" would be the false branch after the first trace

put a print string at minimum off that and see if you get the false firing

so the actual input isn't firing?

again, the only way the second trace wouldn't fire is for the branch to be false. So that means it IS firing, but the start/end vectors might be not what you're expecting or something along those lines

Let me be clear so we're not talking in circles. There are 2 possible outcomes of the MulticastFire Event. The first trace will always fire. Then either is True, and the second trace fires, or it's false and nothing happens

What I'm understanding from you is that you're saying sometimes the first trace fires but the second trace does not

the ONLY way that can happen, is if the first trace returns false

So what you're trying to debug is why the first trace is returning false when you don't think it should be

so my recommendation is to draw a debug line with a different color (green, blue, purple, something else) off the false branch, using the start/end of the first trace

so that IF it's false, you get to see what the trace actually was

right now, you can't see your first trace, so you have no way to visualize what it's doing

which means that it was true, and fired the second trace

you haven't shown what's happening off the second trace, so I can't comment on that. But my guess is the second trace is then failing, and theres nothing off the false branch

also I have no idea what the orientation/position of the "sphere" is that you're using at the start point of the second trace

right, so that second trace is failing and you have nothing to debug that off the false

take what I said about a debug line, and apply it here, off the second branch's false, draw a debug line using the start/end of the second trace so you can see what's happening when it's returning false.

I noticed your rifle model is also flopping around in the breeze, as there is no animation to hold it up. This may be the issue

eh I take that back, just watched it again

[maiden wadi]

@swift pewter It's because of your second trace. It has to go past the wall, not up to the wall.

[hollow cape]

yep

I JUST saw that

[maiden wadi]

The first trace should get you a point in space from your camera. The second trace should be from the weapon PAST that point.

[hollow cape]

you are using the trace end of the first trace as the end point of the second trace
