formal echo
#

What I'm trying to achieve is basically... I take the axis values of both forward and right movement, if the player is moving forward and right at the same time - I limit the right movement by 25-50% so you can't run around strafing like a lunatic. But to get it to replicate into the server I'd need to create a custom event with a float input to pass in the right axis...

#

and I've heard that opens up your game to speed hacking

#

and now I'm not sure how to go about it

can anyone see this bug? Or is just me. I want the collison box to collide with fence and the character i play as affect this collision detector. Can you understand what im trying to say : D?

@formal echo In Cpp there is a GetMaxWalkSpeed() but in BP I don't really know how to handle this correctly let me check

formal echo
#

I think I figured it out

#

I can just set the default walk speed to the sprinting speed, then change the axis value to the amount I need to multiply to get the walking speed and crouching speed. Ex. Default sprint speed 600, if I want max walk speed to be 300 - I just set the axis value to 0.5

maiden wadi
#

You'd have to set both values to about the same on clients and server. So speed hacking isn't really an issue here since the client wouldn't be overriding the server and if they speedhack it'll just make the client's pawn snap back into place.

formal echo
#

not sure how viable that is

fallow creek
#

What is delta ?

viral torrent
#

change it axis value is tricky

#

and yeah since you set the max walk speed on server it should be fine for hack speed

formal echo
#

Why is changing the axis value tricky?

#

to be honest I havent tried it out yet, just finishing it to test if it'd work the way I wrote it just up above

blazing delta
#

Hello, new here, and got 2 questions;
1] is there a way to implement/add sockets to a procedural mesh in blueprints?
2] Is there a way to even add sockets to a procedural mesh?

maiden wadi
#

@fallow creek Delta is often a term used to explain the difference. For example in tick it is the time between two frames drawn to screen. It can be looked at as how much of something you need in a time frame.

fallow creek
#

Fps contious movement like a character moves one place to another then it shows the difference of last postion and current position?

maiden wadi
#

That can be viewed as a delta, sure. They're more often used to predict next movements. But there's nothing saying it can't go the other way.

you don't have a spring arm component in your pawn ?

maybe the issue 😄

do i put the spring arm as a child for the camera?

viral torrent
#

camera is a child of spring arm

mental tendon
#

@dawn gazelle how would you make it available for actorcomps too?

tall pine
trim matrix
#

If this is what you are trying to achieve then you can accomplish that with this

tall pine
#

yeah thats what i want

trim matrix
#

place a camera actor in your world

#

and in the level blueprints add these nodes to get started

trim matrix
viral torrent
#

@mental tendon I think the only way in BP is to create an event in your actor with the Add Component node and call it from your component

#

but you loose the flexibility of component

tall pine
#

i got it to work, now i will have to set it up somehow to follow the player behind him, as the ship just flies away into the distance

viral torrent
#

maybe use a spline

trim matrix
#

you want the camera to follow the player ?

tall pine
#

yeah

trim matrix
#

but not snap to him?

tall pine
#

nom kind of like an endless runer where player can move left right and the camera stays in middle

trim matrix
#

a few ways you can do that

#

if the character can only move forward on the X axis

#

then you could either set the game camera to move up at the same speed

#

set the camera to move forward at the same speed as the character*

#

well that's probably the best way to do it

#

I'll think of an example and get back to you

#

I don't even know what a spline is though so jack might be on to something

@trim matrix I believe @weak kindle wants to do something like this, except instead of having it activated by the mouse have it activated by a trace:

@trim matrix @tall pine about spline the idea is to setup a spline that can be for the terrain or one specific for camera and get position on spline using FindLocationClosestToWorldLocation to know the location of spline of your ship

@green briar if the animations really do work for him then there is an issue somewhere in your logic

@orchid garden Not sure if you remember but I made the camera switch work in the end while the players are loading from the lobby inside in the new level . This code you see is inside the Player controller.

The problem I got now is that, while it is switching to the new camera, it is not using the camera that's inside the level, it seems to use just the blueprint of that camera and centres it inside the playable character.

How could I make a proper reference to the camera inside the level that I can use to put in the Player controller Blueprint?

hi

#

how can i fix this ?

#

i got 4 the same blueprints and 4 different meshes in the construct

#

i only can use one construct

maiden wadi
#

Construct is just a function that runs while the object is being placed for the first time, either when it's being spawned for gameplay use or placed in the editor. You can't have four different construction scripts for the same class.

anyone know if there is a way to turn a curve value to a variable for a timeline?

is there a way to take the 4 meshes in the same actor and put it like that?

thanks authaer

ow i have to set it i think xD

@trim matrix Not sure what you're trying to do?

im making a covering system on the cars :p

#

so i dont have to make it over and over again :p

rain egret
#

Any way to improve procedural mesh generation and have it slowly be generated at runtime and not stutter?

orchid garden
#

@maiden wadi only asking you cause you've made a day/night cycle, is there a way to control when the stars begin showing after the sun reaches x point in the sky? I've noticed the sun sets on the horizon at about 16:50, but the stars don't start showing till 18:00, im wondering if i can manage to make the stars show at like about 17:25 instead.

static charm
#

Rider, depends which part is causing the stutter, i use async thread to combine my procedural meshes. Collision generation is costly too

rain egret
#

I make cube structures out of premade mesh data with simple convex collision

📎 image0.png
static charm
#

if you are making a lot of the structures at once, like through a For Loop, then you'll have to spread the creations out over time.

rain egret
#

Makes sense, but all of that happens in a function so I can’t really add a delay node

static charm
#

Yeah you can keep the main code inside the function but put the begining/loop outside the function

#

But if it's only creating like 3-10 sections it shouldn't stutter too bad.

#

Also if you Nativize the blueprint and Package the game, it will solve a lot of Loop performance issues, since Nativize turns it into c++.

rain egret
#

I will look into nativize thanks

#

Since it’s all in one function there’s not really a outside loop

static charm
#

Well you can just make the first part not a function.

#

Although, since there loops inside, even slowing the first loop might not get rid of all stutters.

#

But like i said Nativize when Packaging will help a lot, or you can put some of the code into Async Threads.

orchid garden
#

wouldn't adding delays inside that cause issues with the past vector? i.e. previous getting overridden by the next before delay ends?

static charm
#

the delay would be for the first part

#

so that it doesn't loop it all in one Tick

orchid garden
#

wouldn't the delay need to be done before the vector is created is what im asking?

rain egret
#

Oh that’s a local variable

orchid garden
#

ah okay

#

is it constant?

static charm
#

do u see him overwriting the vector?

#

its coming from outside the function.

orchid garden
#

nm

#

my brain was over thinking 😉

#

each function call is independant of the previous... wasn't thinking function was thinking chain.

static charm
#

noonga, you can search blueprint vs c++ and read about 3 days worth of material on the topic, but here's a summary

rain egret
#

Thanks for the help lads, I will test it out later

static charm
#

blueprint has about 90% exposed functions of the available c++ you can do in ue4.

#

you can manually expand capabilities by buying/finding plugins or writing c++ that exposes more blueprint.

orchid garden
#

@static charm so if im looking at it right, and with what your saying to stop some of the stuttering... wouldn't the only place he would need a delay be right about here?

📎 unknown.png
static charm
#

Yup! unfortuantely we can't put delays in a loop. We have to edit/make a custom loop node with a delay inside the loop itself.

#

or one can use a Set Timer on a loop with a counter

orchid garden
#

i was just going to say a timer with a self kill

static charm
#

yeah ive had issues with custom loop delays. so I usually end up using the Set Timer

orchid garden
#

or .. just pause timer by handle, then after kill the timer.

#

idk... probably overthinking again.

static charm
orchid garden
#

anyone know how to control when the stars show on a skydome?

static charm
#

like in the default Sky BP?

orchid garden
#

yeah

static charm
#

hmm, i think by default it uses the rotation of the levels main Directional Light

orchid garden
#

seems they don't show till about 1 1/2 to 2 hrs after the sun passes the horizon.

static charm
#

but you can turn the auto feature off and manually set the sky with a slider i think

orchid garden
#

and the stars don't seem to show till its rotated to about 45 degrees below horizon

#

trying to make it abit more... realistic.

static charm
#

do you need your setup to be dynamic sky or is it just a static scene?

orchid garden
#

its dynamic

#

er if im thinking properly... sun moves position depending on time of day

static charm
orchid garden
static charm
#

you can edit that < 0 check and make it so the stars blend in at whatever sun height you wnat

orchid garden
#

sun height is determined by... rotation?

static charm
#

depends if u have a light source selected in the skyblueprint

orchid garden
#

yeah the light source is set in the blueprint

dawn gazelle
#

Oop.. didn't realize I wasn't at the bottom of the chat XD

orchid garden
#

i was just looking for a simple way to change the float value @dawn gazelle , went with basic math from a given value and the fixed value 🙂

#

@static charm there seem to be several spots it does that abs check for the starts (update sun direction, refresh material)

static charm
#

good catch

maiden wadi
#

@orchid garden Been away for a bit. Are you using the default skysphere?

orchid garden
#

@maiden wadi yep default skysphere with sun defined in it.

maiden wadi
#

The stars are based on the material's parameters. AFAIK, Sunhight is the major player for that, but Star Brightness also plays a role.

orchid garden
#

hrm... so the stars start blending in at 0 sun height and become visible at -0.7 so.... to get them to start showing when the sun gets to the horizon, i'd need to modify the abs check to.... 0.7 instead of 0?

static charm
#

i put in 0.2 for both checks

#

adjust from there

orchid garden
#

I also have a issue when the player turns/moves, the stars seem to vanish from the sky?

#

nothing i do to the abs check seems to change anything.

static charm
#

did u edit any other part of the blueprint? might have changed its overall behavior. especially if you said the stars disappear when the player moves.

orchid garden
#

yeah im not getting that, im getting the same results with its being 0.2 or 0.0

maiden wadi
#

@orchid garden More or less the higher that both Star Brightness and Sun Height are, the brighter that stars will be. They just get added to the zenith color and lerped out from the horizon. This is the actual part of the material where the stars are added, that TextureSample being the star material.

📎 unknown.png
orchid garden
#

@maiden wadi , all i want it to do is fade to night sooner, rather then waiting till the sun is 45 degrees below the horizon

#

as it sits right now, when the sun drops below the horizon on my day/night cycle, the sun intensity and skysphere intensity get set to zero so you only have ambient lighting lighting the night.

#

but having a bright sky when its supose to be night... just doesn't really work.

maiden wadi
#

Hmm. Without changing star brightness, it's likely that you could just multiply SunHeight before inputting it into the Abs node for the set material parameter. The one Gallon just posted a moment ago.If you multiply it by.. two? I'd assume that would bring out stars twice as fast if you clamp it after multiplying.

lean compass
#

how can i do camera tilt when strafing?

maiden wadi
#

Maybe a larger multiplier, but still. Should show stars sooner with higher multiplier values.

orchid garden
maiden wadi
#

Try like.. 5000?

#

You might even need to input larger than one. 🤷‍♂️

orchid garden
maiden wadi
#

Well that's odd. I wonder..

#

What is your Star Brightness setting at?

orchid garden
#

im in 4.25.4

static charm
#

when sun height is less than 0 is picks A

#

when it is 0 or greater it picks 0, multiplying A input has no effect on the switch over point

orchid garden
maiden wadi
#

That's fair. You might need to up the < a little above 0.

orchid garden
#

i set it as high as 10 and it still showed the stars at the same point as the above picture

static charm
#

did u edit both abs checks

orchid garden
#

yep

#

tried with just the one in the material, and then both

static charm
#

the one in the material gets overriden by the blueprint and at runtime

orchid garden
#

its stuff like this that just totally dumbfounds me because while its working for one person, and i can do the exact same thing and get a totally different result, doesn't make any sense.

static charm
#

well to be honest it sounds like you've added/changed a few things

#

it's possibly overriding something.

maiden wadi
#

What are you currently doing for the SetMaterialParameter?

static charm
#

if you save your level and test out a fresh blank level with the sky, you'll see it work

orchid garden
#

this is just the thrid person template level

#

far as what im changing via my day night cycle for the sun, just its rotation and light intensity. for the skysphere - the light intensity.

orchid garden
orchid garden
maiden wadi
#

Try the < 0.2 as well.

static charm
#

oh

#

whoops my bad

orchid garden
static charm
#

i also increased star brightness and didn't realize it

#

by a lot

#

my bad brother

orchid garden
#

little lower on the sunheight, but still happening about the same time of day.

#

which means, the sun height is being modified but the stars showing are still happening at the same 45 degrees below horizon

hey, I'm struggling to understand how to work with different systems with blueprints in unreal. Specifically how to pass on variables into a blackboard for example

#

I understand that it's map agnostic, but what would be the right approach to pass a variable, for example a location of some element, in a map to a blackboard, in order to make the AI move to that point?

orchid garden
#

@maiden wadi the only way i seem to be able to get it to somewhat work is by speeding up the suns rotation to reach that 45 degree angle after passing the horizon.

jagged burrow
#

sorry for hijacking guys

maiden wadi
#

@orchid garden Out of random curiosity. What happens if you just simply input straight 1 into both star brightness and sun height?

orchid garden
#

same thing

maiden wadi
#

@jagged burrow Nah, you're all good. To change an AI's blackboard from blueprint and not from the behavior tree, you just need to call GetBlackBoard on the pawn(not the AI Controller), and use the blackboard to SetValueAs. Drag off of the KeyName input and start typing Literal, it'll give you a node for a Literal Name.

I'll go over this

okay this makes ZERO sense.

maiden wadi
#

@jagged burrow You'll get there. Curiosity is the best tool. So is simplicity. If you're making something that's getting too complicated for you to follow on your own, stop. It's likely there's a better way or you're missing something that could simplify it a ton. But just try making small things. Copy some stuff from games you enjoy. You'll be learning new things for decades.

shouldn't it be showing the stars?

Move your sun to the horizon and check the RefreshMaterial checkbox on the instance.

Just a quick question, sorry to interrupt, I have 3 possible scenarios (exec and branch on the top left). Each comes with its float value (on the bottom). How am I supposed to pick only the only that's currently active? By replacing all the braches and sticking in Select nodes?

Anyone here pretty good with bitmask enums?

@formal echo Things like this are most often done in functions for this reason. The Branch False/True is easy. Use a Select Float. But differentiating the execution lines return value is what I'd recommend using a function with different return nodes for.

Is there a way to switch a skeletal mesh to ragdoll mode in the middle of an animation without resetting its pose? I'm setting Simulate Physics to true while an animation is playing, and while that cancels the animation like I wanted to, it also resets my skeletal mesh's pose, which is not what I wanted. hathonk

faint pasture
#

each bit corresponds to tile data such that 10000000 is solid, 01000000 is walkable, and 11000000 is a cave (solid + walkable)

rain egret
#

@static charm sorry to ping you, you suggested earlier that i use a set timer node. i looked into what that is and i understand that it will fire a function with a delay. however i dont know how this would help me in my case since all the examples i saw it being used in simply call the function but dont feed it any information

faint pasture
#

00100000 is water, and 01100000 is bridge

odd ember
#

in most cases it doesn't really make sense to use over explicit enums since the speed of bitmasks is amortized by BP speed

faint pasture
#

I'm only using bp to prototype the rendering right now, the bitmasks are used in mapgen (wave function collapse). Anyway, I'm just using an int to tile class dictionary right now

#

I figured it out. There is relatively simple day/night cycle for someone who doesnt want to use level blueprint. Just tag your sky sphere with "Sky Sphere".

📎 unknown.png
#

It works as separate object (blueprint)

maiden wadi
#

@upbeat copper Get rid of half of that and just use GetActorOfClass if you don't care which instance of it you get. There's nothing wrong with what you posted. Your Skysphere's Directional Light reference is null. It hasn't been told to use a specific directional light.

upbeat copper
#

Oh. thanks 🙂 That is simpler.

odd ember
#

not sure why you'd not want to use level bp in this case but hey

upbeat copper
#

I dont want to use level blueprint because if i end up converting my code to c++ then it can be easier (maybe) 😄

#

Or atleast i want to avoid using it

odd ember
#

doubt it. the level blueprint was designed to function as a manager for level actors

#

you can supercede it in some cases but if you're doing level specific logic it is really the best place to put it

maiden wadi
#

@upbeat copper Realistically, if you convert this to C++(and it's not a bad idea even in blueprint), you'd just combine these actors all into the same actor by using their components instead of using multiple different actors anyhow. It'll avoid you having to iterate over the actors list to get the skysphere all of the time.

odd ember
#

yeah GetAllActorsOfClass has more impact on your performance than the level blueprint will at this point

#

(or get all actors with tag, same thing)

candid hull
upbeat copper
#

I replaced it with get actor of class. But if i want to have multiple levels with sun's do i need to combine all of those actors to one?

odd ember
#

realistically you'd want a subsystem if you're doing it in CPP

upbeat copper
#

Subsystem?

maiden wadi
#

One actor just simplifies it. One actor to drop into the level instead of two.

odd ember
#

subsystem is a cpp only feature

#

but can be exposed to BP for calling

#

a subsytem is the closest you get to completing the S part of ECS in UE4

upbeat copper
#

Okay. maybe i'll stick with level blueprint for my blueprint prototyping 🙂 Its likely that i will then convert all performance critical code to c++

#

After i get basic concept done

you've got plenty of ways of dealing with that

I assume your level isn't going to be a flat plane

well i want them to be able to go out into the water. is there a simple way to make it look like it goes on forever?

odd ember

tbh this is highly contextual on the type of game you're making

#

a big enough water plane

I think a water pizza in this case is better

orchid garden

i don't think you understand

odd ember
#

maybe not

orchid garden
#

they wouldn't just be 'floating' on top of the water.

97% of games probably just darken the water at depths the player will never reach and expand the landscape at least that far.

i'm trying to import fbx, and it's size is 300mb, when importing reach to 100%, unreal engine stop responding forever

odd ember
#

you can make currents that force players (and everything really) back onto the island

maiden wadi
#

@gritty elm Why is it so huge? Maybe simpify the model a little?

odd ember
#

you can engineer some teleporter work to make it seem like the water goes on infinitely once they reach a certain depth

#

there's a lot of options

orchid garden
#

300mb... what you importing a city?

maiden wadi
#

Yeah, that FBX file is at least 50x bigger than it needs to be unless you're trying to make a movie or something with some billion polygon object.

orchid garden
#

i think my biggest fbx is about 1mb tops.

maiden wadi
#

I mean even with a 100k poly model and some animation work, I'd be hard pressed to get one over 6. 300 is insane.

@orchid garden Is the black line your end of land underwater, or your "beach"?

orchid garden
#

yep Authaer

#

(even my animations average at 600kb)

odd ember
#

use a depthfade node on your water material?

maiden wadi
orchid garden
#

plan is to let them reach the bottom @odd ember

odd ember
#

I mean the subnautica example is good. various military style games do similar things even on land

orchid garden
#

do plan on having a invisible border to stop them from going past a certain point.

odd ember
#

you could also do the currents that I suggested

orchid garden
#

invisible border is simpler 😄 currents i don't have a clue about

odd ember
#

well yeah it depends on how much effort you want to put into it

zealous moth
#

i am scared to ask what this is

maiden wadi
#

Depends on how clear you want the water at the depth. Post process darkening can hide a landscape pretty close. Sharp dropoff could keep you from having a lot to render past the invisible border. Slow tapering with clearer water means more level design past the level depending on camera angles.

orchid garden
#

@odd ember depends on being able to to it or not, not the effort. borders I can at this point, currents being i have no knowledge about it means I can't do them. Functionality first, Eyecandy and special effects after.

odd ember
#

currents are functional though

#

they would push you back

#

that was the point

#

how you'd represent that in cosmetics is an open question

orchid garden
#

and i point you back to my previous statement.

odd ember
#

just saying your previous statement said functionality first

orchid garden
#

you seemed to of missed a KEY part about Currents.

#

and i would consider currents being special effects applied to players yes.

odd ember
#

doesn't make them less functional though since they do perform a gameplay function. pushback is a mechanic, once again, whether you want it or not

orchid garden
#

"here you know absolutely nothing about how to make this work, even though your just trying to get the basics done you should do this now!" yep seems logical.

odd ember
#

I'm also not forcing you, it was a suggestion. I'm just saying it's functional, not cosmetic as you would otherwise imply

orchid garden
#

currents just 'thinking' about how they would react with the player would be both functionality and cosmetics to be perfectly honest. hense why i labeled it as 'special effect'.

orchid garden
maiden wadi
#

It's just an extention of pretty much everything else about game design. Hide it.

#

There's a reason that so many games abuse darker atmospheres. It makes level design incredibly easier.

odd ember
#

even in level design it's not a grave concern as most players aren't invested in breaking the game world

orchid garden
#

@maiden wadi btw, the problem with the stars n' night not wanting to change, seems to have something to do with me changing the suns rotation, I edited the timeline curves for the sunset time / lighting / fog and have it working pretty good now.

#

when you say fog im assuming Exponential Height Fog?

maiden wadi
#

For the hiding effect?

orchid garden
#

yeah for hiding effect

but there's a grain of wisdom here: make the borders of your world uninteresting 😉

orchid garden

i followed some random tutorial and i created 2 variables with nothing in them, then "get" them and plugged into that rotator

dawn gazelle
#

So you're not setting them anywhere?

tall pine
#

no

dawn gazelle
#

There's your problem.

tall pine
#

atleast in the tutorial it wasnt

#

do i need to set them?

dawn gazelle
#

You'd need to set whatever the forward rotation is, and then whatever the start rotation is +/- 90 degrees, but you'd probably want something to make sure a player isn't currently turning before starting that timeline.

is it possible to apply float values to a vertex?

rough blade
#

@faint pasture Im aiming to make a tank combat game, various parts of the tank will have different armor values (float) and the best way I can think of doing this is somehow apply a float value to each vertex that my traces can read.

zealous moth
#

@tall pine a few issues with your setup. So alpha goes from 0 to 1 and your timeline goes from 0 to what, 60ish? You want to set it up to go to 1. You should also have your timeline length be the max time. You have 3 set but your length is 5. Set that to 3.
Finally, are you rotating a player controlled pawn or just an actor? If the former, you need to rotate the player controller as well.

#

@rough blade maybe not vertex but you can either have boxes or a skeleton and do damage based on that hit.

tall pine
zealous moth
#

@tall pine there are a few gameplay hitches though

#

what if i pressed it twice in succession?

#

you'd be better off adding rotation to the mesh and clamp it at a specific value while being pressed and the reverse when released

tall pine
#

how i would go about doing that?

zealous moth
#

use "add rotation" node with a retriggerable delay

tall pine
#

so i delete the entire thing which comes after the A button node and replace it with the rotation thingy

zealous moth
#

you dont need to delete it

#

if this works for you and you ant to commit to a button input to trigger a timeline, that's fine

#

you'd have to work on what happens if you press it multiple times

#

anywho, just food for though

tall pine
#

nothing happens, and the player is stuck in that position

zealous moth
#

i know, since you don't have a reversed input 😛

tall pine
#

ya, so im looking to hold A which makes the plan flip 90 like in that picture (almost, need to fix the amount)
and upon release go back to standard position

#

il need the input key held down?

zealous moth
#

no no, you have a "released" input in the A button, just plug in the logic

tall pine
#

oh i plug into reverse

zealous moth
#

you'd need to copy/paste that timeline and use the reverse, but yet 😉

#

yes*

tall pine
#

i copied and pasted the entire thing for pressed and released, i plugged the release into reverse but the starship still is stuck

#

is this intended?

zealous moth
#

you will need to actually develop the reverse logic

#

the reverse of the reverse is the forward

has anyone done a realistic moon cycle? the moon oribits the earth every 27 days, and its phase cycle is 29.5 days (from new moon to full moon), curious about the math involved for that to place the moon properly in your world...

zealous moth
#

cycle = trigonometry
You can probably derive it to obtain what state of the moon it is in

orchid garden
#

well it seems like it would be eaiser if the sun didn't orbit your world and was the other way around.

#

the phase state thing i don't think would be too hard, but my brain just can't seem to do the math for the moon oribit to the world... i think the sun orbiting the world is whats making me go 'gah erg ooph' every time i think about it.

dawn gazelle
#

This seems to work well for me.

#

The actor will automatically reset to 0 and left and right are handled, so long as you bind your input axis correctly.

zealous moth
#

i think he wants to do star fox

dawn gazelle
#

Yea that's what I figured too, but right now it seems mostly just the plane rotation.

You can right click on the pins and break them

quick and dirty way to take a int of 1 and display it as 01?

Append -> first pin 0, second pin plug in your int.

but was curious if there was a quick n' dirty function that did it like there is for floats

what function is there for floats?

# upbeat copper But what when i move to using c++?

if you're moving to cpp you'll have to redo your code anyway. there's no point looking towards optimizations when you haven't even finished your prototype. and what's in the level blueprint may still remain in the level blueprint regardless

tall pine
#

@dawn gazelle i built up and plugged in the same script for flipping right, but in-game the ship only does halfway the rotation before stopping
i replaced the 90 with 180 at the beginning in the float multiplication node and it seemed to fix it, but whats the reason for that?

orchid garden
#

im optimizing as i go, throw it together, optimize, test, optimize, text, move to next part.

orchid garden
dawn gazelle
#

Then you don't need to duplicate it - it should work with just the one input axis.

Change minimum integral digits to 2?

maiden wadi

Why would that be replicated?

#

@peak cipher You do realize that it's not broken, right? That's getting the time from your computer. It's not supposed to be networked. You can't network with the assumption that two machines are on the exact same millisecond of time. If you build off of that, someone' just going to cheat by moving their PC's time ahead a couple of minutes.

hey guys im having a really hard time making my camera not suck, i modified the ball roller so that the camera follows the ball very well, but if i move my mouse in or out it will either zoom into the ball too closely, or get a top view of the ball

#

it makes it hard to turn becuase the ball turns in the direction of the mouse

static charm
#

do you want the ball to follow the mouse direction?

#

just remove the mouse axis input from the directional movement

#

and have it only move directions with key input

thorny marsh
#

@lean thistle The Area of each individual rect added together must be less than or equal the Area of the space your filling.

#

This will give you the maximum number of rects you can fit.

#

(Potentially with space remaining)

#

Then you would need to figure out some mechanism for placing them appropriately.

#

Im assuming you have predefined Rects available that you then want to use to fill the area.

royal rain
#

no

#

one sec

#

i mean i needed the ball to only move in forward in teh mouse direction

#

i cant move with a and d anymore but that kinda doesnt ruin anything

my problems is the camera moves into the ball's ass crack or birds eye view

and it thats what makes it too much to handle

dawn gazelle
# upbeat copper I still get zero from this

Timespans only contain the values set in them. If you have 0 set for seconds, then when you "Get Seconds" you'll get only the value you've set in the seconds field. It's not meant for converting a day into the number of seconds in a day.

If you need to have anything specific for each character, then you make it in their blueprint and overwrite the input.

i.e. character meshes, animation bp's

stiff chasm

so do i have to have 2 of theese and use a boolean to choose which one it should listen and ignore?

No. Each player gets their own player controller.

You are a player controller. You possess a character. your inputs are routed to the character that you posses.

stiff chasm
#

so do i use a bool to separate what input it accepts?

lean thistle
#

@thorny marsh the issue is it’s not just the area that matters, imagine a skinny rectangle with an area of 10 (10x1) remains, but the rect that I want to place has an area of 6 but is 3x2. This won’t fit even though the area is less than, because both dimensions are greater than the space im filling

dawn gazelle
#

So if we both happened to choose the same character, we would each get our own copy of the character, we each posses our own and our inputs would be routed to our appropriate character.

# stiff chasm <@!218956378654507008> So i what does the player controller do in this situation...

The player controller is the interface of a player to the game. The player controller is normally used for commands that are character independent, for example, opening up the main menu, pausing, etc. The player controller can also be changed based on the game mode. The character is something that can be controlled in game. Any controls relating to the character should only ever be placed in the character, not in your player controller.

orchid garden

@dawn gazelle intresting, watching tutorials, im seeing them do one or the other (menu & player interaction) either all in the controller or all in the character :/ guess tutorials fail again.

@lean thistle Yes understandable, however you know those constraints so you can choose the best fitting elements.

lean thistle

Thank you @thorny marsh , Speaking it out helped me. I suppose I'm mostly concerned with the placement of the widgets so maybe I should forward my question to #umg

thorny marsh
#

That would be ideal.

lean thistle
#

Thank you

dawn gazelle
#

For example, lets say you have a "character select" menu. Both your first player and second player will want to be able to choose their characters. This would be something handled in the player controller. The individual players should not need to have separate input events.

This is beyond what I've worked with myself, but this guy gives a very basic means of getting two players set up without creating separate inputs.

@rain egret I'm hardly an expert but spline meshes may be an approach if you want beams to go from point-to-point with the potential for curves. Just throwing that out there.

#

Each node point in a spline (and by extension a spline mesh) has a transform and also tangent vectors.

rain egret
#

That’s interesting thank you, however I need it to be procedural

orchid garden
#

can't spline meshes be procedural?

dawn gazelle
#

Yes

rain egret
#

Okay? Hm, i mean made in blueprint using the one procedural mesh component. It all being in this one component is important

tight schooner
#

Each spline mesh is its own component so if that's your criteria, I suppose it wouldn't be suitable

rain egret
#

Yea

#

You see since only the root has collision It makes no sense have an elaborate structure outside of the root since it won’t collide with the environment

tight schooner
#

well, components further down the hierarchy can easily be colliders as well (incl. spline meshes, though there are some complications with them)

#

but personally idk jack about procedural meshes so I can't help you there

rain egret
#

I disagree, in all my research nobody has ever said that this is how it works. If I have a pawn that moves only the root will collide

Sure those children will have a collision but if I run them against the wall they will just phase trough it

My event tick just stopped working. I added it to an empty actor class and its not firing off, I connected a print string directly to it to make sure it wasn't just some glitch but it's just not doing anything. Is this a bug?

#

It works when I simulate the blueprint but not when I hit play

#

If you check your class defaults, you'll see a checkbox for actor tick enabled

#

You can also control it with the node, Set Actor Tick Enable

@somber quail It has to rebuild a lot of shaders. Does it actually crash with a crash log, or "stop working". Because it's still working if it's the latter. Even on my very simple small project with almost nothing in it, switching to medium at first causes a full rebuild of over six thousand shaders. Takes about two minutes of freezing before that even comes up.

@untold girder I can't seem to replicate this. No matter what, using your values of blue always changes the particle to the correct one. None of these types make any difference. The two variables at the bottom, one is a FColor, the other is FLinearColor

Hi everyone!
Not sure if this is the right place to ask but I'm trying to play a looping video seamlessly with no success..
Every time the video loops I get a black frame or a hitch.
Is there anything I can do about it?
I HAVE tried turning off auto-clear on the media texture, change the video codec, container and even framerate without success...
Thanks in advance for any lead 🙂

Hey qick question, how to best limit rotation of an actor relative to another actor?

I wanted to acomplish that with getting relative angles of each other but I am not sure how to do that the way I want it to

@subtle portal so I would recommend trying to use this to reset and regenerate whatever it is that you need to for your procedural mesh

#

@subtle portal or you can try to use the construction script in the Blueprint to do what you need to do; the tricky thing is that you are saying most of the work is done in C++ so I am not 100% sure how to handle your case; but construction scripts and call-in-editor events should help, or at least point you to the right direction

of course you can simplify a lot if you don't need to clamp all axes.

Hi folk, how can I get reference of spawned hierarchical static mesh actor created in construction script?

worthy tendon
#

beware that you get different results if you swap min and max. for example if min is 0 and max is 45 your rotation will be clamped to [0, 45]. but if min is 45 and max is 0 your rotation will be clamped to [45, 360] @meager idol

why I cant see my c++ class?

to reparent??

maiden wadi
#

@stable fjord What engine version, and what is the parent class?

stable fjord
#

I migrated this blueprint from another class

#

Another project*

#

4.23

#

Engine version,parent class is an AActor

#

UObject_Cannon_Ball (name doesnt matter) in c++ deriving from AActor

#

In other blueprints I see this c++ class

What's the current parent of the blueprint right now? Just AActor?

None

Hello everyone! I have a quick question if someone can help me: I'm looking to create an in-game menu where I can change the niagara system, something like a visualizer change with the press of a button. Can anyone point me in the right direction? can't seem to find the right tutorial

maiden wadi
#

What was the parent class in the last project?

#

If it wasn't Actor, you might consider changing that to like Actor, then migrating.

stable fjord
#

It was an AActor but It is my own class deriving from AActor

#

My own c++ class

maiden wadi
#

Which may as well be a unicorn as far as the new project is concerned. There's a few posts about migrating blueprints. Most of them seem solved by reparenting the blueprint to a native base class.

#

May or may not work.

But If I am looking for a simple Actor to reparent, I dont see it either

Thanks for reply @tight schooner . I was looking for that but Add Instance node have only integer output?

tight schooner
#

@trim matrix yeah instances of an HISM component do not have component references

#

Cuz each instance isn't a component

#

You should open the... palette or library window? ... I forget what it's called

#

But you can peruse the nodes related to hierarchical instanced static mesh components there

#

And you use those to affect the individual instances

Ok thanks @tight schooner will look into that!

Hello! The Multi User BP from 4.26, is that only for the UE editor, or can I implement it in a finished desktop app? Same for the iPad virtual camera from the virtual production system. Is it likely to have that work at runtime as well, with the desktop app as a host?

split crescent
#

I have a map that is divided into grid tiles. When I place an actor on the grid tile in the editor, I want it to perform some logic to place it in the center of the tile. How would I achieve something like this?

maiden wadi
#

@split crescent I normally do that by keeping a grid size variable somewhere. You can do it manually if your grid sizes never change. But all you need to do is divide your actor's X and Y location by your grid size, round it to the closest integer, then multiply that by grid size. Depending on your setup you may need to add or subtract half of the grid size from that.

trim matrix
#

Hi, I packaged an AR project for the android phone, but it has a black screen on the phone and it doesn't seem to use a camera at all.

split crescent
#

Thank you @maiden wadi :)

maiden wadi
#

Also, make sure you actually ROUND the float to the nearest integer. Plugging the float into an integer will bring up Floor, which will round down to the nearest. So even 2.99 will become 2 instead of 3.

Hi! How to insert to this following array a Child Actor Component

I would like to store them

#

I have a BP object Cannon and looking for a way of conversion to this array

#

Tried to get a child actor but without any results

#

Cannon_Second is a Character

dawn gazelle
#

Cannon Second is of type "Child Actor Component" where your array is of type "Cannon Second". You can make your array of type "Child Actor Component" then you can store the "Cannon Second" objects in it.

stable fjord
#

Yes, but in this case I will be able to use functions from cannon ball object?

#

Thats the point

You're asking a question that no one could answer.

theres nothing else set up yet

Try turning off DoCollisionTest in the spring arm.

fair magnet
#

@maiden wadi that wasn't it

maiden wadi
#

Is the spring arm attached directly to the capsule?

fair magnet
#

yea :o

#

Also I don't think it's the springarm nor camera because the whole character is rotating too

maiden wadi
#

Yeah, just double checked that. Something is causing the capsule to turn, and no that's not normal behavior.

#

hmm

#

I found where it sets the name-in the binding

dawn gazelle
#

From what I've heard, you don't want to use bindings for text values. You're better to create your own function that sets the text within the text box in question and then call that function when you need it.

trim matrix
#

okay

#

so this function where it sets the function to make it inside the widget or in the controller?

stable fjord
#

instead of dragging then inserting and so forth

trim matrix
#

hmmm

dawn gazelle
#

You need to set the text in a reference to the specific text box.

trim matrix
#

this way?

#

to set it in a variable?

#

yes, it works nice

dawn gazelle
trim matrix
#

a okay

trim matrix
dawn gazelle
#

In the function

trim matrix
#

okay

like this?

#

yep

okay

the set name works

now if we make change the name works will be perfect

#

If I want to check what type my pawn is, should I do a class comparison?

orchid garden
#

if the dynamic light is behind the hair model and the camera directly on the other side, you end up with a bright glow effect like above

#

it doesn't seem to block the lighting at all, texture is two sided. Turning 'dynamic shadows' off on the hair mesh makes the entire hair glow.

fair magnet
#

@trim matrix I'm not sure for which purpose you're checking but I personally would use tags

orchid garden
#

Anyone know how to stop dynamic lights from doing that? doesn't happen with static lighting.

You don't have this function on this blueprint

You have to get a link somewhere to the object that got this function

With what you are doing, you should use trace line (or another trace function), and cast to the hit actor the function take damage

If you want to make a blueprint that contains a section of a level like a room that contains other actors like spawn points, is the only way to place these actors within the blueprint to use a child actor component?

#

To clarify this is just to be able to drag and drop each spawner actor in the component view of the parent actor. If there's a better way please let me know! I can't use sublevels as it needs to be spawned at a specific location

Can you try doing the same here but 0 out the Z instead?

Oh also, your INput Axis for up and down - you should only need 1 input.

When setting up the inputs you can set a value to 1 and another value to -1

you'll want some type of base class probably, if I understand your issue correctly

coarse forge
#

k. Yeah so I made an interface for my pickup actions.. but I need to set the bool that says the object itself is actually being held

#

it seems I can't just get ActorClass and see it

#

since the actor being held is just AActor and not the exact specific one I'm using

odd ember
#

you'll need to cast it

coarse forge
#

so.. if i Have a bucket, pen, log, etc.. I'll have to cast to all of them

#

or cast to a base class?

wide topaz
#

@maiden wadi @odd ember I'm making level design tools, and want to select things depending on if its used in editor or runtime.
I made myself a simple function

I won't be doing anything with cpp because the project is a blocking prototype, so I won't bother haha

#

Thanks tho! 😄

odd ember
#

be interested to know what kind of level design tools @wide topaz

coarse forge
#

@odd ember so If im reading right.. make an abstract class for my pickup actors, then cast to that to set the being held prop

odd ember
#

pretty much

#

everything gets routed through actor

#

to get your specific subactor type you use casts

#

k.. I have some cpp to change, then I'll get back to the bp part

conceptually with blueprints, I am aware of get all actors of class, is there a way to select only actors within a specific volume?

#

some sort of filter condition I guess, is there a condition/test blueprint node I can rely on?

@violet wagon you may wanna ask in #multiplayer but I believe this is commonly due to the fact that you need to tell the server to move the player character

will do thank you @clear cave

like forest with a bunch of trees, I want to be able to say in the region (sphere) a random tree will be golden or something

what kind of timing are you looking for? is this something that happens when the player enters a place or just at random

clear cave
#

it should happen on begin play, it'll be constant for a game

odd ember
#

you can use GetOverlappingActors from a collision then

clear cave
#

is a collision a special type of actor?

odd ember
#

usually it's a component

clear cave
#

of a sphere actor?

odd ember
#

of any actor

#

sure

you don't need a physical sphere to have a sphere collision

if you create an empty blueprint

you can add a sphere collision

it'll have its own bounds as a component then
