[willow phoenix]

there are often like 20 ways to do something, i like trying to find the most performant way

im spawning ~100 tiles and on those are sockets

[spark steppe]

your current way is pretty certain faster than the one that i had in mind as alternative

[willow phoenix]

oh ok

[spark steppe]

even tho we are probably talking about nanoseconds 😄

[willow phoenix]

not on the 5 year old mobile of my gf

😄

final addition to the code

problem solved, channel can be closed now

i got too much coffee i guess

[native willow]

wait wait, yes they do

im checking out your case, gimme a sec

[willow phoenix]

i may be wrong, but try that on "begin play" instead of the construction script

[native willow]

he does, construct is just a name of the function

from what I understood

[willow phoenix]

ooh sry overread the beginning

[dawn gazelle]

Is it the cast that is failing? Maybe print out the display name of the object you're feeding into the cast?

[native willow]

maybe the pawn is not yet possessed on begin play, try to use possessed event

[dawn gazelle]

I like Niyo's suggestion 😛

[native willow]

I like it as well

run the Construct function on that event

yes, you can do it like that

if you want to be more generic you can create a delegate and broadcast it on the OnPossess, and then bind on it from actor component

use OnPosses

posess

possess

damn

Im trying to accomplish a werewolf-type transformation, where the player starts out as a human and you can see him changing into a werewolf mesh. The problem is I have no idea what to do, any ideas or pointers in the right direction would be greatly appreciated!

[icy dragon]

To get you started, look at morph targets (or shape keys, if you use Blender) and how to lerp every PBR input with a single scalar parameter

It's kinda similar to how Epic did the transformation of Owen in the UE3 Samaritan demo.
https://www.youtube.com/watch?v=XgS67BwPfFY

[willow phoenix]

damn that demo looks cool

and its been 10 years

only thing i do i align nodes in a straight line with Q and push them around for ~9 hours per day lol

[icy dragon]

It's a shame that we never get the executable, but at least the main guy (Owen) did make appearance in the content example project, even if it's just his rocky form. The bad guys also got used on Matinee/Sequencer demos

[spark steppe]

that demo shows once again that good artists skills are more important than the tech behind

[gentle urchin]

For sure. Good artistery can make bad tech look good. Good tech cant fix bad artistry 😄

[icy dragon]

Well, Arkham Knight is one game that managed to get into the same fidelity as the demo, with the same engine nonetheless.

[spark steppe]

wait that trailer is from that game?

[icy dragon]

The demo? No, it was Epic's demo project. Arkham Knight won't came out until 4 years later.

[spark steppe]

yea, im looking at the game right now, the atmosphere seems to be very similar to that tech demo

[icy dragon]

IIRC at the time (2011) they had to chain together 3 GPUs that were at the top. Probably GTX 670 or something.

[spark steppe]

"realtime" 😄

they did a good job at drawing attention away from that

so job done well

[fading raptor]

Incredible! This is exactly what I need, thank you!

[dim robin]

is there anyway to activate CCD through blueprints?

[odd ember]

If it's exposed you can grab it through your actor's collision component

[native willow]

yeah, there is a checkbox in collision category

[dim robin]

the problem is: i made a track with a spline and spline mesh, so the option ccd is not present on the blueprint of the "track generator". I setted up the CCD on the spline mesh component, but it behaves like nothing. my ball keeps on going through the wall if it has high velocity

[odd ember]

... what kind of speed are we talking?

[dim robin]

it's a pawn system, not character system. I apply an impulse/velocity on the ball

[odd ember]

and can you check if it happens for slow speed as well?

[dim robin]

slow speed no problem

my max velocity right now is a float with 3000 value

[odd ember]

maybe it's worth logging the speed just to see what happens

[dim robin]

wait i grab a sceen and show you

[odd ember]

tbh I would ask in #legacy-physics

[dim robin]

right

[cunning anvil]

Anyone can tell me why the top part is not being sent to the box while the bottom part is. There seems to be something wrong with the for each loop but have no idea why.

[bright frigate]

Quick question - what's happening here in terms of timeline behaviour? Are the nodes after "Set Intensity" getting called repeatedly as the timeline progresses? Should they be attached to "Finished" pin from the timeline instead?

[sharp rapids]

Yeah

[bright frigate]

Should I instead put those other nodes before the timeline?

[sharp rapids]

Anything hooked to the Update pin will be called continuously

[sharp rapids]

Depends on when do you want to run them

After the Timeline has finished? or before?

[bright frigate]

well the basic behaviour I've wanted is to have the lights slowly brighten up

that's about the only thing that guided me to set it up this way lol

[spark steppe]

you want them before the timeline

pretty sure

[bright frigate]

I remember that on the way down I had to put the set visibility after the timeline so that when the lights are dimming, they turn off after the light goes through the reverse timeline

[sharp rapids]

Those seem like two different cases

When running forward, you want those nodes before the timeline

When running backward, you want them after the Timeline has finished

[bright frigate]

yes?

[spark steppe]

yea looks good

[bright frigate]

sanks

the switch off (bottom) path isn't working though, so gotta hook it back to the update line?

[spark steppe]

no

that would make it invisible on the first update

whats happening before all of this (whats not in the screenshot)?

[bright frigate]

no it works fine because that's how it was before I thought about improving this

[spark steppe]

that can't work fine

[bright frigate]

Just a branch to see if it's dawn or dusk

[bright frigate]

sorry forgot to mention there was a condition to check if it reached 0

so when it reached 0 it would then fire it

essentially what Finished is supposed to do I think

[spark steppe]

yes

[bright frigate]

yet attached to the finished pin it curiously doesn't fire

I have "use last keyframe" enabled as well

[spark steppe]

that's indeed weird

what if you disable use last keyframe?

[bright frigate]

erm, it worked now (without messing with keyframe either)

really strange

lol

[dawn gazelle]

It's generally a bad idea to do an == check with a floating point number. Even if you are setting it to 0.0, it could still somehow end up being calculcated as 0.000000001

[bright frigate]

good point

[odd ember]

use NearlyEqual

[dawn gazelle]

^

[bright frigate]

wait no something is really weird. The timeline seems to persist its last-state. So at some times if I play the game, it flips the whole cycle (light during day, off during night) and then after that it's correct

[bright frigate]

thanks

never even knew that node existed, or forgot

[odd ember]

from a solipsistic point of view, those are the same

[storm vigil]

Hi. How do we loop the camera shake when I am still pressing the run or spring key? It seems that there is no looping within the camera shake class, I could set it to -1 on the oscillation duration but it doesn't stop the camera shake when I release it. Thank you

[sharp rapids]

and What's before the branch?

[odd ember]

you have to do it over time

I'd suggest a timeline for it

[bright frigate]

just the event

@spark steppe don't do it!

[spark steppe]

what if you use the play from start from the timeline instead of play?

jesus christ

[bright frigate]

I'll hook it up though I'm having a hard time to repeat the freaky flip behaviour but that would be the solution indeed

[storm vigil]

REPOST. Wrong pic

Hi. How do we loop the camera shake when I am still pressing the run or spring key? It seems that there is no looping within the camera shake class, I could set it to -1 on the oscillation duration but it doesn't stop the camera shake when I release it. Thank you

[spark steppe]

you are again working with comparsion instead of your enum

which we set up in a painful process

with blood sweat and tears

[storm vigil]

I see probably connected to the scale float right?

[bright frigate]

I knew it! Haha I know, but it's like this only here because I want fine-grain control over this part

otherwise I'm using the enum for everything else!

[odd ember]

well you removed the image so now I can't see what you mean

[storm vigil]

Sorry I reposted it. But I think I got the solution, i set the oscillation duration to -1 to continue playing and on the walking function I added the stop all camera shake 🙂

[mint grove]

Hello everyone and so happy I found this page. I'm working on a game and I'm makeing a full body character for the game and doing IK and everything else I'm having issues with picking up guns in the world. I've watched a bunch of tutorials but they are all for just the hand models and with a full body it doesn't reall work well. The only other problem is the arms do not stretch or scale to the controllers when you go farther than the arms length can any point me to a video that would help or I could add when ever info you would need

Do weapons need to be static or skeletal meshes mainly firearms? Any help would be appreciated

[odd ember]

I don't think any of these questions pertain to this channel. I certainly don't know the answers. I'd look in #animation and #graphics. failing that, #ue4-general

for picking up guns in the world, I think I need to understand the use case

[mint grove]

Well I'm not worried about the animations yet I can do that just can't get it to go from the ground to my hand. I'm designing a campaign game so the player will be able to pick up guns and they go into inventory but right now I'm mainly focusing on just being able to pick them up like pavlov style I'm also doing this in vr I'm sorry I didn't say that.

[odd ember]

yeah but like

what do you mean get it to go from the ground to you hand. do you want the character's animation to go down, pick up the gun from the ground, and then use it?

[mint grove]

Well I'm vr and full body when you bend over the animation is already done in the IK system. Would a picture or video help explain?

[odd ember]

definitely

[mint grove]

One second then

https://youtu.be/OarTVMBBrgQ this is my prototype from like 3 weeks ago I've cleaned up all the bugs and it works great now just working on weapons

I'm going to record a new video that shows what is going on more right now while you look at that so I can explain more

[odd ember]

in conventional games you could conceivably fake the pickup, but I don't think you'll have the same affordance available in VR

[mint grove]

Ok so the video I'm uploading now is shows some weapons on the table I've made alot of trials so the ar on the table is a parent and child class I added a static mesh and was working on picking it up but in static mesh you don't have the ability to drop the clip and reload so I have to use a skeletal mesh. The guns that go flying are the skeletal mesh but the two that go into that hand are static mesh they are in the same blueprint I don't see why the skeletal mesh goes flying away and won't let me pick up but the static mesh has no problem. I've got 5 min left on the upload and I'll send the new link

And also saying thank you so much just for looking into this I've been racking my brain for a week now trying to get it right I was watching one of vr macros videos and he said to come here for help in the comments.

If you need anything to help you understand more just let me know and I will do my best to supply that information

https://youtu.be/Uo5fFkf0Rmk here is a better look into my problems

the ar4 goin at a 90 inst my problem i just put the static mesh in the skeletal mesh so i could see if i was getting anywhere close to picking up the skeleton

this is the ar 4 parent pick up system

this shows the hierarchy sorry i should of showed that

[odd ember]

the logic you have requires the gun on the ground to be the same that you hold. you can do that, but I'm not sure if VR requires specific sockets for the hands or whatnot

have you considered asking in #virtual-reality ?

[mint grove]

im so sorry i didnt see that channel

ill go there should i just post the videos and this there or will the bot get mad at me for cross post

[odd ember]

no worries, that question could still pertain to this channel

it's just a question of expertise

the bots won't but mods will

generally wait a bit before asking the same question in multiple channels

rule of thumb is 1 hour

[mint grove]

yea very true and thank you so much and ok ill go work on my project and then come back to this youre awesome man

[odd ember]

good luck

[warm swallow]

Has anyone had any issues with on component begin overlap not working?

Oh and gravity is broken too

I set an actor to not use gravity and it still does

[odd ember]

interps usually happen over time

looks correct. you could use a rotator instead and take the Z value

[arctic radish]

is there a way for me to like drag the lines around? I don't like them all merging together it makes it look bad

[odd ember]

the target rotation is the rotation you want? I don't know which rotation you want

[dawn gazelle]

You can double click on a line and it'll create a reroute node... You can also create reroutes by right clicking and selecting "Create Reroute Node"

[arctic radish]

thanks

[odd ember]

well you can take the previous frame's rotation as your current rotation and this frame's rotation as the target

but generally you do this at the cost of responsiveness

which is why I said it's better to do in animation

so it's just the cosmetics that are affected, not the controls

if you imagine every call to the tick function as being a sequence that happens over a frame

you can do something at the beginning of the frame

and you can do something at the end of the frame

so for instance if you do all your logic at the beginning of the frame, then that logic isn't used again until the next tick call, next frame. this gives you opportunity to save that data as the data of the PreviousFrame

[dawn gazelle]

Isn't that basically what he's doing now? The Finterp node takes the current value as input, then sets the current frame variable (which would be the "previous" frame value)... Next tick it'll be reading the current value variable again which is again, basically like reading the "previous" frame?

[odd ember]

you may find that it will still be extreme enough for people to feel it btw

[odd ember]

no they're setting the value before doing the logic. that makes it current frame, not previous frame

in this case, after doing the logic, they could do something like TargetRotation = CurrentRotation

just as an example

anyway order of operations matter

[feral ice]

I want to spawn grass on a rock randomly generated how should i do this? I need some advicve

[spark steppe]

do 1.000.000 line traces 😛

did you check the loop thing?

[feral ice]

WOW I HAVE NEVER THOUGHT ABOUT THAT :p

haha

[feral ice]

Yeah it worked!

[spark steppe]

but you still want to get rid of the traces, i guess

you can use the actor bounds to limit the area where you trace in

or is your area really 20.000 x 20.000 ?

[feral ice]

If i had a material i could only apply the material on the rock and then i could spawn the rock with grass aldready on it. But now i spawn rocks first and then spawn grass using a bad method

[feral ice]

neve rheard of that what is that?

[odd ember]

more of a #graphics question, but there are foliage "grass" types that you can apply per material.

these spawn automatically

[spark steppe]

it's actually a box thats around your actor

[feral ice]

I guess this would only work on landscapes and thats not my case

[spark steppe]

also i would reduce the traces on the amount of grass you want to spawn

[feral ice]

a box around my rock?

[odd ember]

they're based on the material, not on landscapes

the material doesn't care if it's applied to a landscape or not

[spark steppe]

that sounds like the best approach

[feral ice]

wait i dont understnad. So you mean that if i applied the material on the rock it would spawn grass on it?

[odd ember]

yes

materials aren't the same as just a flat "texture"

they have shading logic in them that allows for greater flexibility

[feral ice]

is it called foliage material? Or what is the name

[odd ember]

foliage grass type maybe? better to ask in #graphics though

[feral ice]

yeah i agree!

[orchid spruce]

Hello guys! I'm using the default first person shooter template for a project I'm working on. Does anyone know how to make it so the worlds kill plane doesn't delete my character?

[dawn gazelle]

I know you can set the kill-z distance in the world settings... Apart from that, I'm not sure there is a way to stop it from destroying the actor at all.

[orchid spruce]

Yeah I've been messing round with that. I'll see if there's a way to do it in the gamemode itself. Thanks anyways for the fast reply!

It's all good, I managed to find a tutorial in the docs about respawning a character. Thanks again anyway 😁

[worthy frost]

@orchid spruce you can override a function,but its c++ only 😦

[gentle urchin]

You could also block the character from moving below kill z

Locking them right above, and doing your own handling if so

[worthy frost]

just set the killz to a big negative number, then make your own overlap box at your kill z

that is how i have seen games do it

[odd ember]

funny how killz is read differently from killZ

[sharp rapids]

There's a space between kill and Z, that's why I guess 😄

[odd ember]

that too, but still

I read killZ and kill Z the same

but different from killz

[trim matrix]

Probably because the "Z" is a capital, which means we read it differently

It's like a parent letter

[sharp rapids]

'peep'

'peeP'

Kinda like this? 🤔

[odd ember]

yep

p_P

[orchid spruce]

So I used the KillZ Volume in the volumes menu, it seems to do the same thing, it just destroys my actor

[serene zinc]

Hi guys! Im totaly new to BP. And having so much issues with the target on blueprints, kind of solved most of the issues. But I cant find how to get reference from an Widget. Any ideas?

I tried this but did not work 😦

[plucky harness]

i have a random character generator and when that character is created he has a struct, which is filled with attributes on creation, how can i create json file with specific fields from that struct?

[dawn gazelle]

You usually don't want your widget controlling or doing anything outside of the widget blueprint itself.
Think like widgets are just visual display of the data they have access to.
Instead, feed in values to the widget. References to objects, or what not.

For now, if you just want the first instance of the Widgets array that you have (that's what that cube like icon indicates) you can pull off from the "Found Widgets" and start typing "Get" and you should see (Get a Copy). Use that, and you can then get an individual reference from the array.

[serene zinc]

Thanks @dawn gazelle for that reply! Iwill try it out 😄

[dawn gazelle]

Nothing available directly in the engine in blueprints. You can code your own functions in C++ or there are JSON plugins on the marketplace. There's a free one that I haven't tried but looks to convert structs into JSON. https://www.unrealengine.com/marketplace/en-US/product/dbjson

[plucky harness]

ty, will check it out

[worthy carbon]

Hi! I want to create an thirdperson shooter game (Singleplayer) but i don’t know what type of game i should make… does anybody have an idea

[odd ember]

I have plenty of ideas that I can sell to you for $20 a piece 😎

[dawn gazelle]

I charge $19

[odd ember]

dammit

[earnest tangle]

You mean ideas aren't dime a dozen?

[dawn gazelle]

Not when they're high in demand.

[earnest tangle]

the bot actually does give kinda fun ideas

if you just want something

:D

[odd ember]

whoever is selling ideas for a dime a dozen has too many ideas that aren't worth much

[earnest tangle]

ah you're selling premium ideas?

[odd ember]

my ideas are high quality. they've been resting in oak casks for years until they're ready

[dawn gazelle]

Labelled as "CE's Finest" 😛

[odd ember]

best enjoyed while lightly intoxicated

[dawn gazelle]

Try narrowing it down a bit more to what you want to do. Whatcha wanna shoot? Whatcha wanna shoot with? What's gunna shoot out of the thing you wanna shoot with?

[odd ember]

or even... do you want to shoot?

[dawn gazelle]

Good point.

[odd ember]

or start formulating interesting questions

what if you can shoot, but all the targets are wrong targets?

[wet wren]

hey there i used to be a developer in other game engines but i recently moved to unreal engine, is there any good blueprint tutorial series on youtube you guys suggest?

[odd ember]

if you check the pinned messages there's a bunch

which languages have you worked with?

[wet wren]

thank you, i have worked with lua

[odd ember]

ok well, I don't know lua, but you may find blueprint a bit more structured since I know lua isn't necessarily OOP based

[wet wren]

im planning on learning blueprints first then move onto c++

[odd ember]

while you're learning blueprints, if you're not already familiar with OOP principles, I would suggest learning them

as they are both applicable to blueprints and cpp

you'll end up getting much more mileage for your buck

[wet wren]

ooh thanks for the tip

[odd ember]

you're welcome 👉 😎 👉

[atomic salmon]

Also go to learn.unrealengine.com, there is plenty of free high quality tuts to get you started, including introductions to Blueprints.

[feral ice]

how do i get the rotation of a linetrace?

[wet wren]

alright thanks!

[misty island]

Is there a way to crate curve tables inside the engine?

[atomic salmon]

Meaning you know the start, then end and you want to know the rotation of that vector in world space?

Calculate the vector End-Start and pass it to MakeRotFromX

[gentle urchin]

Or find look at rot

[atomic salmon]

Also yes

[atomic salmon]

This is literally what FindLookAtRotation does MakeRotFromX(Target - Start);

[gentle urchin]

I expected as much^^

[stuck plaza]

Is there a button to compile all blueprints in project/folder at once?

[odd ember]

nope

there's a command

for opening the project having them all recompile

[brazen merlin]

wouldn't playing in editor compile all blueprints?

[stuck plaza]

I think no, last time i tried it it didn't

[brazen merlin]

I am thinking of Auto Recompile Blueprints in Editor Pref under PIE, but this is only for the current level, though I'm pretty sure its more than that because I launch a separate level from my main menu

[leaden dock]

hm i created a public function for a blueprint and try to call the function from a reference in another blueprint

but the function doesnt show up

any idea why?

oh nvm

i referenced it as an actor instead of the blueprint type

🤦‍♂️

[solemn zephyr]

this doesn't uncrouch then jump in the same input, why not?

[fiery swallow]

I hope you're dedicated enough to do that. When you get to the point where you are really good with blueprints it's hard to start all the way from the bottom again with c++

[brazen merlin]

it looks like it should, if you disconnect Jump at the end when the input is pressed, does it un-crouch though?

[zealous moth]

Bp and cpp are the same thing.... tjebonly hurdle is pointers and you can learn it in a day

[icy dragon]

Eh, not really. When you get to the point where you're really good with BPs, you'd sooner or later craving for performance, and C++ is where it's at.

[mild jacinth]

nvm - found solution, use Get Owner (Target is ActorComponent) then plug into New View..

[icy dragon]

Also remember that BP and C++ can go hand in hand. You could get the benefit of C++ ticking and the ease of asset loading of BP.

[zealous moth]

^ that and loop performance

Try to do 3 nested loops in bp and not waste 50 fps

[solemn zephyr]

it still un crouches without the jump node, it seems like it gets either eaten or ignored for some reason

[feral ice]

I really need some help! Im spawning rocks in my environment through instancing. I want to access the location of each rock so i created a map but i couldn't get that to work. Now im doing the classic array. Im having two arrays, one instance array and one vector array. Whenever i want to spawn a rock it does not show in my array how many rocks there are in the array.

[brazen merlin]

what if you branch before the jump?

[feral ice]

rock has 0 elements

[fiery swallow]

You were that eager? For me it was really a lot of "I could do this so much easier right now in blueprints" the whole time learning c++

[solemn zephyr]

what condition would I branch with?

[brazen merlin]

that IsCrouching is false

[fiery swallow]

that said I've seen maybe millisecond differences between blueprints and c++ when blueprints are used properly

[atomic salmon]

Check size to fit when setting the array element

[atomic salmon]

Or use Add

[icy dragon]

Yeah. 60 FPS (16 ms) in modest CPU is one of my top priority, and with BPs, I can't do much with crowded situations.
Though to be fair, BP is good for proto-ing the systems or asset loading, so you have some reference to translate to C++.

[faint pasture]

I'm with you on that. If it was equally as fast and had the entire API exposed, I would only ever do blueprint. I know my way around cplusplus decent enough but I'm a very visual person and visual scripting just clicks a lot better.

[solemn zephyr]

that has the same effect, I want a single input to both uncrouch and jump on the same frame

[feral ice]

If i use add it wont work. Whenever i move the main rock actor around the small rocks will find new location and it will into to the recent rocks, i need to start over thats why im using set instead of add

[brazen merlin]

and the IsCrouching bool talks to the anim bp right?

[icy dragon]

I know asset loading in C++ can be fucking painful, thus sideloading the ticking to C++ and doing asset loads in BP.

[atomic salmon]

Then check Size to Fit

[fiery swallow]

Man I hear your, some people like things crystal clear and I respect that, a few ms differences here and there aren't that important though in my opinion unless it's a super crazy competitive game where one ms difference can change the game at a given time

[feral ice]

that seemed to work

[solemn zephyr]

the bool isn't connected to anything yet, right now it just says whether you're crouching

[fiery swallow]

Honestly though I can't wait for blueprints in 10 years. I have such high hopes, it will be even more spectacular

[faint pasture]

Things that are all depends on how complex your stuff is. I took a system from 8 milliseconds per frame to 0.05 by moving it to C++

[brazen merlin]

So this doesn't work?

[solemn zephyr]

that has the exact same effect as not having a branch there

[fiery swallow]

I don't even know how justifiable that is because it's not even a noticeable difference xd

[faint pasture]

But it would have taken much more time to prototype if I had to do it all from code with compile times etc.

[fiery swallow]

I don't think the eye could catch that not even close

[faint pasture]

That's an over 100x speed up.

8ms to 0.05ms

[icy dragon]

I don't know how you can brought that up for optimisation context 🤔

[faint pasture]

And that's just for one system with a test level. Totally unusable in production without the speedup. That's half your frame budget gone at 60hz.

[solemn zephyr]

a difference of 8ms to .05ms is extremely noticeable

[faint pasture]

It's a lot of math and traces tho. Realtime fog of war calculations. For stuff like hooking up inputs and handling events BP is plenty fast.

[icy dragon]

I mean, sure, it's still less than 16ms on it's own. Nay, 33ms.

But multiply that by 10.

[fiery swallow]

you guys have eyeball reaction times like jesus

[icy dragon]

And I was terrible at CSGO, mind you :P

[fiery swallow]

there are 1000 milliseconds in 1 second

if you can notice 0.05 milliseconds

you might be god

[icy dragon]

It's the matter of scaling up, not necessarily inhuman reaction times.

[solemn zephyr]

that's not even the whole picture

if it has to happen every frame on top of everything else 8ms is way too slow

[fiery swallow]

if the argument is you save 1 millisecond here and 2 milliseconds there then I feel like it's situational

[brazen merlin]

well, it doesn't help with or without, so..

[fiery swallow]

but they really don't add up unless there's a lot going on

[faint pasture]

That's not what the argument is. The argument is, that you have 16ms to work with total. If you blow half of that with 1 system before even bringing combat, ai, pathfinding, UI, and everything else in the mix, you're off to a bad start. It's like shopping for food and you blow half your budget on 1 item. You still have to get other stuff.

Honestly in a test map you should shoot for under half of your alloted budget. Then when stuff gets a lot bigger in production you have breathing room instead of constantly having to refactor.

[brazen merlin]

I'm getting confused, MLE_uh is responding to this while I'm helping with their problem, I thought MLE_uh, you were saying that the branch adds an extra ms delay

[faint pasture]

Nah one branch ain't gonna do anything. A thousand per frame will tho.

[icy dragon]

Again, to be fair, BP has advantage of quicker iteration time and easy asset loading, so one can build a proto of the system in BP, and use that as a reference to wrote C++ code, and still use BP for asset loading without using BP tick.

[solemn zephyr]

oh no that response was completely unrelated to my problem

[icy dragon]

Reminds me of that one case of Yandere Simulator

[faint pasture]

Oh yeah for sure, that's exactly how I do it. I do everything in Blueprint and then move what needs to be moved into c++.

[odd ember]

is someone doing get all actors per tick??

[faint pasture]

Hopefully not.

[odd ember]

what's the optimization spiel about

[solemn zephyr]

I don't think timing has anything to do with my issue, the jump node just isn't working in the same input as uncrouching

[faint pasture]

Show your setup again.

[fiery swallow]

oh yeah no if that's the argument then you guys are right 100% if your budget is 16ms and that's what you're going for

[faint pasture]

@solemn zephyr Is Un Crouch a stock node or did you make it? Also is jumping blocked by crouching?

[fiery swallow]

sorry late reply actually in a league game

[faint pasture]

Like if you just call jump when crouching does he jump?

[fiery swallow]

I personally don't think it's that serious though unless you are going for a highly competitive game

[solemn zephyr]

un crouch is a stock node for the crouch function in character movement, you could jump while staying crouched before I added the un crouch node

[faint pasture]

Try un crouch after jumping

[odd ember]

might be that it takes a frame to uncrouch

[brazen merlin]

omg is this not bp talk??? take it somewhere else

[faint pasture]

Yah there's prolly some CMC wonkiness between the 2 states.

[fiery swallow]

excuse you, this is exactly blueprint talk

[wet wren]

thank you, yeah its a long journey hopefully i stay motivated, but i have some experience with some other languages so i know what is going on, even if a little its an advantage :D

[faint pasture]

@solemn zephyr

[solemn zephyr]

I tried that, changing the order doesn't fix it

[timber knoll]

how does that make it more clear haha

[icy dragon]

My game is a single player game, yet I'm more concerned about getting more performance in modest CPU, as opposed to ignore performance issues altogether.

[faint pasture]

Maybe jumping cancels crouch already internally.

[solemn zephyr]

it has the exact same effect still

[timber knoll]

maybe use a secondary color 😛

[odd ember]

@solemn zephyr

[solemn zephyr]

I considered that but I want to avoid having to wait a frame if possible

I'll try adding a wait node though

[nova tartan]

Hi there am I allowed to ask for help here

[faint pasture]

What happens if you jump first?

[odd ember]

I'm saying you might not have a choice

[faint pasture]

Does he jump or uncrouch

[solemn zephyr]

changing the order didn't change anything

[icy dragon]

As long as it's BP related, yes.

[faint pasture]

Well which one does he do?

[nova tartan]

Ok ty

[solemn zephyr]

the same thing as before, un crouch in one input and only jump if already uncrouched

[odd ember]

does it work with just the jump?

[nova tartan]

So basically
I got this error I am trying to migrate 2 ue files together
that is the error bit

[odd ember]

as in, can you jump normally

no crouching involved

[icy dragon]

What's the error message?

[nova tartan]

Seems or work on the other side

[solemn zephyr]

jumping works fine when not crouched

[odd ember]

ok

[odd ember]

go into your animBP

[solemn zephyr]

I checked again and it looks like crouching does disable jumping though

[odd ember]

and see if making a connection between jump and crouch works

[fiery swallow]

definitely commendable to go the extra step, so then you do most things in c++ then over blueprints? or do you use them both equally?

[solemn zephyr]

I don't have any crouch animation yet, the character stays in their neutral pose

[odd ember]

you're not using a template?

[solemn zephyr]

it just changes the hitbox and prevents walking

[dawn gazelle]

Have you tried refreshing the nodes? Just right click on the event and select "Refresh".

[solemn zephyr]

I'm using the sidescroller template, that doesn't include crouching

[icy dragon]

Seems something to do with the custom event output

[nova tartan]

OMG it worked

[odd ember]

does your character have a character movement component?

[solemn zephyr]

yes

[nova tartan]

I dont get it cause I restarted it about 5 times but sure Ty

[odd ember]

look for options there

[nova tartan]

❤️

[icy dragon]

Yeah, BP nodes can be funky at times

[dawn gazelle]

Don't thank me yet. After refreshing them, try hitting the compile button near the top left 😛

[solemn zephyr]

I've checked the character movement comp several times and don't see anything related to jumping while crouched there

[timber knoll]

it doesn't have any afaik

since you have booleans for both, you can manually check

[icy dragon]

I personally set things up in BP first to get the system working at all, as intended, then make a C++ code by manually translating the nodes and the flows.

[nova tartan]

Wait the hoodie It did not work

[odd ember]

bool UCharacterMovementComponent::CanAttemptJump() const
{
    return IsJumpAllowed() &&
           !bWantsToCrouch &&
           (IsMovingOnGround() || IsFalling()); // Falling included for double-jump and non-zero jump hold time, but validated by character.
}```

[faint pasture]

@nova tartan delete those add and remove nodes and make new ones dragging off the inventory data array.

[icy dragon]

Make new Add nodes.

[solemn zephyr]

I don't know how to read, write or implement written code

[icy dragon]

Shit, should've not typing on the phone

[odd ember]

I'm telling you why you can't jump.

it's inside the jump function

[dawn gazelle]

With the event selected, can you take a screenshot of the Inputs? Like this:

[timber knoll]

add this on top

[odd ember]

in the blueprint graph, find a variable called set jump allowed

sorry, a function

[nova tartan]

I made new add nodes but its the same erorr

[odd ember]

requesting != doing

[timber knoll]

pretty sure you can't access those

[odd ember]

that's why I said wait a frame

[timber knoll]

yes that's exactly what I mean CE

[nova tartan]

I use snipit do you need a plugin for that cause My friend said you did but he never said what

[icy dragon]

Try removing the Add nodes, and refresh the remaining nodes.

[timber knoll]

unless you override CanJump

[faint pasture]

If you're using the CMC you need to learn how it handles moves etc. Stuff doesn't just happen instantly, it uses a move list.

[nova tartan]

So I removed the add and remove nodes and refreshed them so the error goes then I try to add the add and remove then it says its not compatiable with targetArray

[odd ember]

well like I said

before

it takes a frame

to uncrouch

[solemn zephyr]

adding a 1ms delay makes it work

that's probably good enough

[timber knoll]

I wouldn't count on 1ms

[odd ember]

same

[timber knoll]

depends on your framerate

[odd ember]

it might not be consistent

[timber knoll]

rather do an approach like

shouldJump boolean

that gets checked next tick and cleared

[odd ember]

assuming that tick is running already

[solemn zephyr]

is there not just a delay by frames node

[dawn gazelle]

Hover your mouse over this. What does it say?

Then hover your mouse over this, what does it say?

[odd ember]

not in the base editor. all calculations in editor is done by real time

[timber knoll]

Can check if canjump == true as safety

[odd ember]

get world delta seconds is ~1 frame

[nova tartan]

Inventory data

New Item

[dawn gazelle]

So the problem is the input on the event.

[solemn zephyr]

would this work?

[odd ember]

try it

[dawn gazelle]

Drag off from your Inventory Data, and create the "add" node. Then drag the available pin on the add node to the event, but NOT to the "New Item" pin that already exists.

[solemn zephyr]

it works in the editor but so did the 1ms delay, .5ms also worked

[odd ember]

delta seconds should be safe. you're essentially taking an average frame time when doing that

[nova tartan]

So like that Datura

[dawn gazelle]

Yes, now drag the available pin on the "ADD" node to the event but not to the "New Item" pin. like this.

[nova tartan]

It does not work

[dawn gazelle]

That's not what I said to do.

Drag from the "ADD" node to the event.

[nova tartan]

Well it creates a new pin

[dawn gazelle]

Right.

[nova tartan]

Aaa thats what you mean sorry

[dawn gazelle]

The current pin is not correct.

[timber knoll]

It telling you that’s not possible means you have an incompatable connection

[nova tartan]

Ty let me see if works

[dawn gazelle]

If you can find this section with the event selected, then you can change the variable type of the "new item" pin.

[nova tartan]

Aaaa
But this comes up is this accociated with the error

[dawn gazelle]

Because you still have the "New Item" pin on there and it is NOT set up correctly.

It's not referencing a valid structure.

[gentle urchin]

Cant you reverse drag?

Just for practicality at this point

[nova tartan]

Aaaa

[gentle urchin]

Oh. I didnt notice datura showing this. Mb 😅

[dawn gazelle]

When you hovered over the struct on the event, this is what it read... It's not the type of structure you want. What you want is a structure of:

[wet wren]

man blueprint is fun

[odd ember]

I should maybe do some code of my own

been slacking all day

[solemn zephyr]

what's the difference between world delta seconds and framerate to seconds?

[odd ember]

technically nothing

but I don't know where you have framerate to seconds

world delta seconds gives you the frame time for the last frame

[nova tartan]

Ok ty

[icy dragon]

World Delta Seconds puts into account the time dilation.

[solemn zephyr]

I saw it said that but don't know what time dilation refers to

[icy dragon]

Basically the speed multiplier of your game. Lowering time dilation down (< 1.0) can create slow motion.

[odd ember]

slow motion

[solemn zephyr]

I see, so I'd want to use world delta seconds for the jump delay in case I want to add any slow motion to the game

[odd ember]

if that's part of your game

or fast forwarding

[odd ember]

it's just always going to be a good indicator of the avg frame time at the time you use it

no matter what happens

[whole dune]

Hi! Quick question: how can you set the location of a bone relatively? So it doesnt depend on the world axis

[odd ember]

it's future proofing yourself

[solemn zephyr]

so just use it for any frame delays

that's very useful to know, thank you

[odd ember]

use it for timers

[solemn zephyr]

unless I want the timer to slow down with time dilation?

[odd ember]

technically the lowest time a delay can do is 1 frame

[odd ember]

then you're facing edge cases

actually no

[feral ice]

How do i get the width of an actor? If the scale is 1,1,1 and i have a cube how do i get its width?

[odd ember]

the opposite

deltaseconds do slow down

[solemn zephyr]

so "takes into account" means it is affected by it

[odd ember]

yes

time dilation slows down frames

that's the whole point

all time is slowed

[solemn zephyr]

what about ticks? aren't those a steady 60hz?

unless I'm completely misunderstanding them

[odd ember]

ticks are using delta seconds all the same

everything in the game

updates per frame

even timers that are faster

will only update on the next frame

(multiple times, if they manage, but still, they sync with frame time)

[faint pasture]

Time dilation adjusts WorldDeltaSeconds so stuff just slows down alongside the world.

WorldDeltaSeconds = ActualFrameTime x TimeDilation

[odd ember]

(previous frame time)

[solemn zephyr]

doesn't everything being tied to frames make it very difficult to include frame rate options in the game?

[faint pasture]

Ya I've always wondered about that. Is there a infographic around that goes over the frame timing and order?

[faint pasture]

Don't tie to frames, tie to time.

Don't say "this lasts 5 frames" but instead say "this lasts 0.08s"

[odd ember]

you can look at the update function which should be somewhere in engine

[solemn zephyr]

then shouldn't I make the jump delay 16ms rather than one frame for consistency across different settings?

[odd ember]

delta seconds is fine

it's the closest thing you have to a true frame time

because the engine doesn't know, on its current frame, how long that frame takes

so it takes hte previous

[solemn zephyr]

yes but a delay based on frame time will change based on framerate

so if I want the jump delay to be consistent and include higher frame rate settings should I not make it 16ms

[faint pasture]

You make it whatever time you want.

That's the whole point.

[odd ember]

a delay is always based on frames. even when set to 0 ms it will always take 1 frame

[faint pasture]

Well yeah it'll always round up to frame

[fiery glen]

It gets evaluated each frame to see if the time has passed

[solemn zephyr]

if that's how it's checked why can't I just set it to 1ms

[odd ember]

you can

[faint pasture]

Because what's the fucking difference? You effectively have a minimum delay of 1 frame.

[odd ember]

but it doesnt make a difference

it still syncs on the next frame

so nothing happens

[solemn zephyr]

the length of a frame varies based on frame rate

[faint pasture]

That's like asking why you can't spend 0.001 dollars.

Yes your minimim delay will be 1 frame. Deal with it. Or write a whole new tick function to run at arbitrary timesteps.

[odd ember]

the engine limits you to the tick groups that exist

[solemn zephyr]

how many frames it takes isn't what I'm talking about, I'm talking about real time, a frame delay will be half the time at 120fps as it would at 60fps

[faint pasture]

That is true. Now what's the point?

[fiery glen]

So don't use a 0 time delay?

[odd ember]

yep. so it will take half the time at 120 fps

[fiery glen]

Generally I use those to just deal with race conditions

[odd ember]

yeah I hate that we have to do that

I was considering using more built in polling

[faint pasture]

You don't have to, you can design your stuff correctly to not require a delay. But if it works it works.

[odd ember]

if you're aiming to have your game run at 120 fps you have to design for it basically

framerate independence would be nice

[faint pasture]

Design it right and you can run your game at 1000.

[odd ember]

I used to think timers had it

but no

anyway this conversation is moot since it's not something you can easily fix in BP, and it will have little to no bearing on your actual game

[solemn zephyr]

yeah this is a bit pointless

[faint pasture]

Ok so on a other topic, what's the approach to making your pawns completely agnostic to whether they're driven by a PlayerController or AIController? I'm thinking just have Player inputs call into an event layer, and AI also calls into that same event layer.

[odd ember]

sounds like a plan

or you can create a composite component for it

[faint pasture]

Anyone here ever done pawns that AI drives around by inputs and not by pathfound movement?

[odd ember]

mm no

[faint pasture]

Basically where ai says "move forward" not "move to that location"

[odd ember]

I don't think that thinking works with AI well because AI is generally goal based

or I should say, purpose based

[faint pasture]

You still have the goal, it just only exists in the ai controller

It's just interfacing with the pawn exactly as a player would.

[odd ember]

but IMO what is smartest is having either a component or the player controller dictate inputs that interface with the AI so you can possess each AI and still retain functionality

for what it's worth I have my inputs in the player controller, not inside the pawn

[faint pasture]

Yeah I might transition to doing that. I know there's a reason why I switched back to on the pawn but don't remember why.

[odd ember]

but I would avoid having AI call into player input events

I don't think that will go down well

[faint pasture]

No I don't mean that. I mean both calling into a layer.

[odd ember]

it could work but again, you'll have to consider how that is a paradigm shift from goal based AI

[faint pasture]

If AI could output input events that'd be dope but I havent seen that done.

The AI controller still has a goal, it just accomplishes that by controlling the pawn exactly how a player would. This is for a roguelike shooter and player and enemy pawns are all the same base class. Nothing special about the player character.

[odd ember]

I mean that's just a systemic approach

but AI will likely still have to control like AI

if you want true player controls for the AI (which may not reflect well in the player experience) you'll have to abstract backwards from the AIs having a goal and how they achieve them

and I think you'll have a hard time doing that regardless

[faint pasture]

Wait till you see how we're doing ai perception lol

[odd ember]

well if it's anything like this, it sounds like you're crossing the river to get water

[solemn zephyr]

not to bring that debate back up but just pointing out that the first image works and the second one doesn't so the entire problem is just some kind of bs with blueprint

since adding 0 time should have them both update on the same frame the two images should do the exact same thing

[faint pasture]

Minimum delay is 1 frame

[solemn zephyr]

I see

[faint pasture]

It's due to how the CMC works, you'll have to modify/extend the CMC or work around it.

[solemn zephyr]

never mind then

[slender idol]

Hey, what's the best way to get a per BP instance random? I'm trying to manipulate some flickering lights and they end up flickering in the same pattern due to the random number being the same in all isntances.

[faint pasture]

The problem comes down to passing 2 moves to the CMC in 1 frame, there's some sort of a priority or something there.

[faint pasture]

Per BP on begin play, get random number.

How are you getting your random number? I'm more surprised that they are all the same than not.

[slender idol]

random float in range in an update timeline

[faint pasture]

Do you have 1 actor with multiple lights or multiple actors?

[slender idol]

multiple actors with 1 light each

[faint pasture]

Show your BP, idk how tf theyd all get the same random numbers.

[slender idol]

intensity is exactly the same on all instances

[faint pasture]

Are you sure your random float is doing enough to even notice?

Try just multiplying your flicker track by random float in range 0.5-2

Or whatever will be obviously noticable.

[orchid spruce]

Anyone able to help me get rid of some errors? They aren't game breaking but they keep showing up when I stop playing in editor

[faint pasture]

Not without seeing them. Post enough info for someone to work with.

[orchid spruce]

Here's the error, I'll post the code in a sec

branch highlighted in yellow is the one I'm being directed to

[faint pasture]

How tf do you get a blocking hit without hitting an actor?

[orchid spruce]

I'm hitting into a geometry brush. Could that be causing it?

[faint pasture]

Try print hit actor

Maybe brushes are special

[orchid spruce]

yeah it works fine when I hit my valid walls, those are meshes. I get the error when i hit a brush

[faint pasture]

What does it print when you hit a brush? Is a brush an actor? I'm not exactly sure if it is.

[icy dragon]

Also it's not like BSP brushes should be used for final level logics.

[orchid spruce]

Yeah it doesn't print anything

Should I be replacing them with static meshes after I've finished testing?

[icy dragon]

Yes, you should replace them with static meshes once you're done with the level design/blockout.

[orchid spruce]

Awesome. Thanks!

[zealous moth]

what in the world is this?

huh gone if i recompile

[odd ember]

recompile and save

and see if you get it again

[zealous moth]

nope gone

[odd ember]

then no problem

[jagged kelp]

hi all, I am trying to make it so when a player is within a volume any movement they take becomes relative like this https://gfycat.com/incompletefaintbaboon the only clue I have right now is "in that example the sphere is stationary and only the flat platform is moving. The objects on top of it inherit their location from the platform and the physics stay relative." so the core of my question remains >> how does?

[hardy merlin]

Hmm. A naive approach may be Attaching the sphere to the platform.

[jagged kelp]

I tried attaching the the player to the sphere, without any success but I can try attaching the player to the platform itself

[novel robin]

I am trying to get a runtime BP to work in movie render queue and epic suggests this workflow

I have no clue how to get the "target level sequnece" and target map node

[odd ember]

those are soft references

[odd ember]

try using "snap to target" for all rules

[novel robin]

ahhh thank you!!

[jagged kelp]

the player got scaled up to the size of the platform, I made it scale and rotation world and snap to target for the location rule and while I hover above the platform I am moved along with it, as soon as I touch the platform it zooms out from under me, but then I get dragged along inside the volume hovering again

[storm vigil]

Hi. Is this timer ok for a stamina consumption tied to running and sprinting? This was using tick previously and I tried using a timer. I attached the beginning of the node to the event begin play. I wanted to use 0.1 seconds but it was not that smooth when the UI bars are decreasing/increasing. So I tried using 0.05 seconds.
The float was also tied to the delta time on the Finterp for the blending of the walk speed and running/sprinting, so I could only find the get elapsed time by handle to derive a float value instead of the delta seconds.
Not sure this is optimal. Thank you

[odd ember]

try relative instead of snap? for location

[jagged kelp]

relative did the same scaling

[odd ember]

leave scale and rotation to world

[jagged kelp]

ah will try relative location now

[odd ember]

what is the question?

[storm vigil]

Hi. If using this timer at 0.05 seconds and get elapse time handle for float is better than a tick and using the delta x seconds for the float? Thank you

[odd ember]

performance wise? yeah it's better, as long as tick is disabled too

tick runs once per frame, at 60 FPS that's around 16.7 ms, or 0.00167 seconds. so updating only once every x frames is fine

[jagged kelp]

I am still flying off the platform unfortunately

[storm vigil]

Thanks. So this one here right I will disable? Will this not affect the tick from the codes like the timeline (which uses the tick I am not sure) within this blueprint and also the Anim Blueprints which uses tick or is this for this specific blueprint?
Regarding the tick interval (sec), is it the same if I set this to 0.1 or 0.05 seconds and use the default code using the tick?

[odd ember]

if you are physically on the platform, and it is moving, then you will inherit some physics from the platform

[odd ember]

for the most part it will only affect the actor you are on, and nowhere else. I would not recommend doing it for animBP and PlayerController

both of those are special cases

if you're looking for performance increases, you can also go into every actor and disable tick on their respective components

[storm vigil]

Thank you for the insights, I will have to read up more about optimization. I am trying to find some parts that can substitute for a timer. So far the template I am working on only uses the tick for the stamina and blur effect. My only concern was that I have several timelines in this blueprint, ow and I also have a weapon sway and weapon block IK in this BP that would be better running on a tick for smoother animations. Anyway, this is only a single player game.

[odd ember]

timelines are unaffected, they tap into tick themselves

[odd ember]

the special cases here being PlayerController controls the camera, and animBPs need tick to propagate onto the animation thread

[novel robin]

me again. so i managed to get hte Target Sequence as a soft onject reference

but cannot seem to figure out the target map

i cant find anyhting discussing how to soft reference the map

[sudden lynx]

Anyone know how to make the mediasound component louder? Making the attenuation radius bigger doesn't seem to help.

[tropic pecan]

Hey there, I have a question. Does anybody have an idea on how to sort out a slot in order such as like with a party unit slot. I'm trying to create a party structure and I realized that when I try to switch units to follow, the slot switches up and messes up the slot order. I had the idea I'd have to put a number on them but just how is there a way to get a structure to follow an other number on each unit and keeps it from messing it up. My units are inside of a map(Dictionary) in the variables of a controller blueprint. Should it be setup differently for unit blueprints? I do require to be able to add new ones in a gameplay and remove.

[faint pasture]

like an RPG Party?

[tropic pecan]

Very much yes. It is a complicated thing to explain but I will try to ask for how to sort out the slot and a way to keep it like not matter what happens.

[light token]

Ok very noobish question. I have a project which didn't include any character so I migrated the FPS Character from the template into my new project. What do I need to do know to enable it? I already set the GameMode from the Project Settings to be the one I migrated but when I run the game it doesn't load the FPSCharacter (I put a print in beginplay)

[tropic pecan]

I have my party units in the Controller blueprint I made in a variable map(dictionary) and I've connected to my slots but when I try to switch out them, their slots move around and that's not what I want. I want to slot to function like by number though the unit that has the roll of leader goes in the top while the navigator in the bottle while the normal party members are in the middle. They stay in their certain row even if registered to follow. I ask that is there a hint on how to sort out this way?

[faint pasture]

Why do you have a map? What's the key and what's the value?

[tropic pecan]

What I meant by map, I do mean the variable.

[tropic pecan]

I'm asking on a way to sort out a slot in a way to keep in order regardless of what happens.

[faint pasture]

I know what you mean, why are you using a map? Maps don't have a concept of order

[tropic pecan]

Ok, sorry. I'm using a map because that was the structure used in the sample blueprints I'm using cause that's how they were able to set it up when you want a unit added or removed.

If I had to use an array. I guess that would have made sense in a way but that still doesn't quite get to a slot order yet for me.

[faint pasture]

I would represent a party as either a naked array with leader being Member 0 or a struct with a leader reference and members reference array

[tropic pecan]

May I ask what is the naked array? I did have the idea of creating a Inumeration to sort out their rolls in the unit blueprint. But then make a list in them in some way without being interfered. I don't understand on how a struct would do it though trying to add the Inumeration in it while added in the controller blueprint in the list would have made somewhat sense. But, do you know any sort of structure that can sort out a unit party slot?

[tropic pecan]

I'd presume the naked array is the array chosen from the variables right? And I require to all the player parties their? I still would have required to connect what stats they have when added if that's the case but still, a hint.

[novel robin]

Me again.

anyone have any idea how to set a soft reference variable for a Level/Map?

ive tried every keyword i can think of to scrub through the options and cannot get anything that functions

[solemn zephyr]

this seems like a good way to do this since the default crouch and jump functions can't be called on the same frame

[brazen merlin]

this seems rather pointless to bring up, I didn't think it worth it but now I'm wondering, wouldn't the Sequence node perform in the order you want in one frame?

[solemn zephyr]

it won't, the order is irrelevant, it's something with the character movement comp that prevents the default un crouch and jump from being called in the same frame at all

Sequence node is more of a cable management tool than a real UFunction.

CMIIW, but I think Sequence node also ignores timing of latent functions like Delay.

[tropic pecan]

If your still there, I'll text again later. I'm about to log off. I do really appreciate some of the advices.

[solemn zephyr]

I can't tell what I'm missing here though, it's supposed to disallow standing back up if the trace hits but it isn't allowing it regardless

oh I'm blind lol

I forgot to connect the exec pin

[brazen merlin]

the start and end..? you want that?

[solemn zephyr]

I fixed it

[brazen merlin]

alright

[solemn zephyr]

the exec pin from the trace to the return node wasn't connected

[novel robin]

So I am running into this same problem
https://answers.unrealengine.com/questions/946184/view.html

[tiny scroll]

Has to be done in level bp

I do believe

[novel robin]

i was already working in BP lol
I am trying to reproduce this

but I cannot get the stupid World Soft References variable (turns out it was nerfed)

Stuck on step 3
https://docs.unrealengine.com/4.26/en-US/AnimatingObjects/Sequencer/Workflow/RenderAndExport/HighQualityMediaExport/RuntimeBuilds/

[tiny scroll]

There is a load an unload node

Think you can specify it as a class

Etc

[novel robin]

Pardon me..but what??

are you talking about the load level and promote to variable workaround?

https://answers.unrealengine.com/questions/946184/view.html

[novel robin]

Thank you, this method worked!

[trim matrix]

I got a question
How do I make it so when my collectable counter reaches a certain number, it casts to a function in my particle BP

[trim matrix]

Im not sure if this is correct

[faint pasture]

That's not what casting is

you CALL a function in your particle BP

Don't use tick for this. First of all, does the Particle BP exist all the time or is it only spawned when your get your collectable number?

[trim matrix]

It exists constantly, I want it to be hidden when the counter reaches 4

[faint pasture]

Instead of asking every frame "Is the counter 4 yet?", just check when you change the counter

Counter = Counter +1
If counter > 4
Do thing

The tick approach is the programming equivelent of the little kids asking "Are we there yet?" 60 times a second.
The proper way to do it is "I'll tell you when we're there."

[trim matrix]

Okay I see

What do I use instead of an event tick

[faint pasture]

Just check at the end of whatever you do when you get a pickup

get pickup, check if over 4, do thing

no tick anywhere

[faint pasture]

Not in the UI, in Event Teru Collected

[trim matrix]

How do I make the function not "read only"

[faint pasture]

Why would it be read only, go to the actual event Teru Collected

You made that event right?

[trim matrix]

This is a read only function

Idk why

[faint pasture]

Not that event, go to the event that is fired when a Teru gets collected

did you make this or is this some example project?

[trim matrix]

I made this yes

[faint pasture]

Do you understand what I'm saying at all? When you collect a Teru, check to see if you have 4 of them. If you do, do the particle effect

it's super simple

[trim matrix]

Yes I understand that

However I dont know how to do it

[spark steppe]

you have to use a reference of your rain system as target

[trim matrix]

I dont know how I'd get that in there

[fiery glen]

I suppose you could get all actors of class

definitely not sure what the #1 intended way of getting singleton actors is in BP

(make subsystems blueprintable you hacks...)

[spark steppe]

that depends on what the rainsystem even is

is it a standalone actor?

[fiery glen]

I think he made a standalone actor with a Niagara component on it

iirc

[spark steppe]

yea then get actor of class

if it only exists once

[trim matrix]

Rain is still visible when 4 is collected

[spark steppe]

we gonna get any further debug informations, or is that everything?

does the event fire?

[spark steppe]

what did you make out of this?

because it looks kinda like a wild guess rather than set up with intention

[trim matrix]

It was a guess mixed with my current knowledge

Should I change this to "equal" rather than "greater than"

Since I want the rain to be invisible when I collect 4

[spark steppe]

=

also you want to use an integer, not a float

[timber knoll]

Didn’t you have a counter in your player a few days ago?

I’m pretty sure I helped you with that 🤔

[trim matrix]

I'm not making a counter

[timber knoll]

But then why do you have a variable called counter

[trim matrix]

When the counter reaches 4 or higher, it'll hide the particle system

That's what I want

[timber knoll]

Yeah but you have the counter in your player

So why have another

[trim matrix]

also whenever I collect one, it fires and moves here

This is the counter in my player

[timber knoll]

Yes so that can also have the same logic

And trigger event elsewhere

Theres no need to have duplicate logic

[trim matrix]

It's not duplicate

The logic in my player tells the UI whenever the item is collected

[timber knoll]

Just looks weird to me that’s all

So when does that counter in UI get updated?

[trim matrix]

Whenever the item overlaps with the sphere

[timber knoll]

Can you make it a bit more specific 😛

What sphere

[trim matrix]

My bad, the sphere attached to the item, whenever the player overlaps with the sphere on the item

[timber knoll]

Then your counter in player also increases?

So the event in player should update it’s counter and pass the value on to UI

[trim matrix]

Is this going to lead towards the particle system or are you just going to talk about the counter

[timber knoll]

Then you can check on UI if that value >=

I’m trying to help you fix that counter because your branch is calling at a wrong value?

[spark steppe]

no

when the player collects increase counter on player, if counter reached 4 notify the particle system

don't add the UI to that

also i said use GetActorOfClass not GetAllActorsOfClass

and you should define the class which your particle system is of, and not braindead collect all actors

[trim matrix]

Thanks

[timber knoll]

Well yeah I’m just trying to keep the logic as similar as current

[spark steppe]

currently theres not much logic 😄

[trim matrix]

Okay I got it to work

[novel robin]

https://docs.unrealengine.com/4.26/en-US/AnimatingObjects/Sequencer/Workflow/RenderAndExport/HighQualityMediaExport/RuntimeBuilds/

So I believe i got the blueprint set up identically, but i am not the best at blueprints so anything goes

but when i wentr to hit play to go into runtime, the engine crashes immediately
same results repeated

[native willow]

check if the ref to a level sequence is valid

[novel robin]

ooo thank you one sec restartin

[trim matrix]

So I want 2 different sky spheres with 2 different Blueprints, how would I do that?

[faint pasture]

duplicate or subclass BP_Sky_Sphere

[trim matrix]

It still uses the same BP when I duplicate it

[native willow]

duplicate the blueprint asset

[novel robin]

Progress! that was it. somehow it got disconnected

Now the screen goes entirely blacck so i assume it has something to do with MRQ

and it did not export any frames.

[faint pasture]

Do you know what a class and instance are?

[trim matrix]

Somewhat

[native willow]

I honesty have no idea on hot to use MRQ at runtime, my earlier advice resulter from reading the log you sent

[trim matrix]

Apparently the BP doesn't exist

[fiery glen]

check the folder you are searching

[faint pasture]

It's an engine content bp

[trim matrix]

It's In the content folder

[novel robin]

i feel like i am at the edge of what is of available knowledge lol

MRQ is rather new to begin with and there is seldom content surrounding it

I should talk to William Faucher

[trim matrix]

huh

[fiery glen]

click this thing in the bottom right of the content browser to see the extra hidden folders

you probably want "show engine content" iirc

[native willow]

I have no idea who that is, I used MRQ myself for a game trailer but only in the editor and not through blueprints

[trim matrix]

Ahh gotcha

[novel robin]

https://youtu.be/FxvF3zncClA

enjoy
this man is incredible at what he does

[native willow]

oh, thanks, but anyway, that trailer I did was my last attempt to use sequencer anyway, the pain I had to went through was not worth the result hah, remember having to download the engine source code to fix a crash that occurred whenever we tried to open a map that was holding a level sequence, I'll stick to programming and hopefully never touch sequencer again

[native willow]

btw is this guy on this server?

[novel robin]

I don't know? i feel like he should. he has other social medias and he is responsive when he has time

[native willow]

try to invite him if you get a chance maybe

if he's not already

[novel robin]

yeah i was going to message him on instagram with a fun challenge 😄

i searched the channel, i only see people posting his work

[trim matrix]

I want the skysphere to be hidden when all the terus are collected, this is correct?

[fiery glen]

it would be cooler to change the properties of the skysphere over time if you ask me

if your goal is to hide the sky I guess that would work?

[faint pasture]

Have you tried it?

[trim matrix]

I wouldn't really want anything fancy, I'm fine with the weather changing instantly

Yeah it doesn't work

It follows the same function that the particles do

[faint pasture]

well then work your way backwards and make sure that event is even being called.

[trim matrix]

But.. it is being called

Because the particles get hidden

[stuck plaza]

I'm making an endless runner kind of game. It works with preset tiles, so I have made 10 types of tiles each with different layout and every time a new tile needs to be generated, a random tile from the that pool is chosen to spawn.
I have a BP_BaseTile which I create child blueprints from e.g. Bp_TileType1, Bp_TileType2, Bp_TileType3 and so on. In each of these children tile I have various actors like Obstacles, Powerups, CoinPickup.
I have a question regarding tile layout creation. So far when I created a new tile by extending BP_BaseTile, to add new actors to this tile I would add ChildActorComponent and select appropriate actor e.g. SpeedPowerUp or Coin, then set his position, done. Is this bad way to create Tile layout? Are there any other ways to tackle this problem?

[faint pasture]

What's particles got to do with anything you just posted? That's an interface call setting the visibility of a mesh. Does that specific event ever fire?

[trim matrix]

That event is the same event that the particles have, there is no reason it wouldn't fire if they're both connected to the same interface, right?

[faint pasture]

That's not how interfaces work. Put a print string on that and see if it's ever getting called.

Interfaces are not dispatchers

[trim matrix]

Oh I see

Well it's not being called

Would I make an event dispatcher here?

[faint pasture]

IDK dafuq you're doing, weather should all be in 1 actor most likely

or it should live in 1 central location that other actors can register with

[trim matrix]

The skybox and rain particles are 2 different things

[faint pasture]

Yes i know but a BP_Environment could have the skybox and sun and weather and all of that

[trim matrix]

I wouldn't have known that

[faint pasture]

but anyways, watch some videos on what Interfaces are

[trim matrix]

Im just going to mess around with it

[faint pasture]

I think you can get all actors of class with interface if you insist on using an interface to do this stuff

[round moth]

I am confused why this isnt rotating my character. I am afraid it might have something to do with my mouse being captured

[faint pasture]

Is your character set to use control rotation?

[round moth]

how do i check that o3o

[faint pasture]

Look at the capsule component

[round moth]

i still cant find it

like that setting

[timber knoll]

what would be a good way to check hits for melee combat, when it comes to low framerate

[faint pasture]

Shape traces

[timber knoll]

has to be fairly accurate for multiplayer

[round moth]

so where can i find that?

[faint pasture]

Try the search box on top of the properties window

[trim matrix]

How can I branch this into both of those

[round moth]

i dont see a properties window

[timber knoll]

so a multibox trace for example?

will that give better results than normal overlaps?

[fiery glen]

it will be a lot faster performance-wise but there are multiple ways to go about the shape of the trace

a lot of melee games do a large "comb" of linetraces along the blade (of a sword)

[timber knoll]

for my game it can be rather simple

[fiery glen]

a simple box/capsule/sphere would work too

[timber knoll]

most of the weapons will be fairly boxy, if not they can still have that simply box collision

[icy dragon]

What are you doing with those Get All Actors of Class nodes?

[fiery glen]

if it doesn't need to follow the real location of the blade/fist/doodad it could even be a simple shaped trace in front of the character

[round moth]

id love some help for my smoothbrain to find that setting

[trim matrix]

They're both different actors that I'd like to have hidden at the same time

[fiery glen]

try this

[timber knoll]

yeah I will at least go for the actual location, especially since the attacks will be animation based

I'll try out multibox thanks 🙂

[fiery glen]

as for the uh, low FPS issue you are kind of praying people run the game at a decent framerate here

because the animation will be sampled as fast as it ticks

[round moth]

no i cannot find it still oof

[timber knoll]

low FPS shouldn't be an issue, but it should somewhat be persistent just in case

[fiery glen]

as long as it doesn't dip insanely low it should mostly be fine

[timber knoll]

you can't have optimal results on low FPS, I am aware

[icy dragon]

Are they supposed to be dynamically generated in different time? Why not get the actors in begin play, save that to an array variable, and get the array on demand?

[timber knoll]

yeah exactly, just looking for a somewhat independent solution

this will probably do fine

[trim matrix]

Becuase I dont know how to do that

[fiery glen]

you can right click the return value of Get Actor Of Class to just make a variable (promote to variable) from that like I show here

[trim matrix]

Ah right

[round moth]

so i think i made it use controller stuff but still dont know why it isnt working

[icy dragon]

Get All Actor of Class is kinda taxing in BP, might better to do it in the beginning.

[trim matrix]

Got it, thanks guys! :>

[faint pasture]

Why would an enemy character ever need a reference to a playercontroller?

That's really messy.

[fiery glen]

some major blueprint spaghetti in the making

[icy dragon]

Indomie Goreng in the cooking 😋

[round moth]

still really confused and lost if anyone has ideas

[icy dragon]

Wait, cables aren't as delicious as noodles

Nevermind.

[faint pasture]

Why does enemy pawn need a reference to player pawn?

[icy dragon]

Isn't there a dedicated node to get player pawn? CMIIW

[faint pasture]

Then get the pawn when needed, not the playercontroller

and yes there is a dedicated get player pawn node

[round moth]

still really confused if anyone has any input

[faint pasture]

Why not cache it just like you've been caching the player controller

cache the pawn, then now you have a nice little reference to pawn

but getting player pawn and casting ever frame is fine

idk why tf you need it every frame but thats whatever

[earnest tangle]

@swift pewter I'd say you could place an event into your gamemode "Player Spawned" or something

[icy dragon]

At least that saves you a cast node.

Also there's a Get Player Character node, if your character class is inherited from Character.h

[faint pasture]

The whole thing sounds spaghet but yeah just get it and cast

that'll be least shitty

[icy dragon]

Is the character supposed to be immediately destroyed when it dies?

[fiery glen]

why not have some kind of value noting that state of being "dead" but not exactly deleted to check if you need to?

[trim matrix]

Is there a way to make my audio a variable

[round moth]

so in my game it starts with 2d like widget spawned on screen and stuff and so you click buttons but can press buttons. would that get in the way of the game reading the mouse movement?

[icy dragon]

Yes. Make a Sound variable (IIRC)

[fiery glen]

might want to have the difference between being in "mouse menu" and "mouse look" mode

I forget the exact binding order

using the mouse in the UI might consume the input straight up... let me try

[round moth]

o3o i dunno how to do that at all

[trim matrix]

As in this?

[fiery glen]

here's an example https://youtu.be/Qspi31qtvpw

this is for UI specifically but I'm not sure if that's what you mean

[round moth]

lets just say yes

all i know

[icy dragon]

@fiery glen what was the variable name for Sound Wave and Sound Cue? I'm not with the editor atm so can't remember exactly which

[round moth]

is that i followed a player movement tutorial

and it didnt work and the mouse was always on screen

[fiery glen]

"Sound Base"?? It's easier to just promote the type to variable

[icy dragon]

Yes, that was it. @trim matrix

[fiery glen]

I'm honestly surprised it's an actor/uobject ref? must be a wrapper or something

[trim matrix]

This is an issue

[fiery glen]

Sound Cue is probably the intended usage

[trim matrix]

Probably becasuse it's an object reference right?

[icy dragon]

That's an Audio Component function, not Sound Base function.

[trim matrix]

Yeah I want to stop the rain audio I have when the rain stops

[icy dragon]

You could get them from Spawn Sound nodes (not Play Sound nodes, as it's fore and forget)

[fiery glen]

yeah, I think you want something like this

(make it a variable of course)

[trim matrix]

Ohh yes I see

Wait

Hm

The rain doesn't necessarily "spawn" in

I just dragged it in

[fiery glen]

I also think you should probably uh, attach this sound to the player somehow

because otherwise it will just make a little sound from world 0,0,0

[trim matrix]

I turned off attenuation or something so it wouldn't do that

[icy dragon]

Or make the attenuation range super huge

[fiery glen]

ahhh, "Spawn Sound 2D" could also work

[trim matrix]

Hmmm

[icy dragon]

Spawn Sound 2D is fine, if you don't want "immersive audio"

And by "immersive" I mean panning according to the camera's listening direction

[trim matrix]

So I gotta spawn it in first, then do this?

[icy dragon]

Do the spawning in BeginPlay or as soon as the rain starts.
Then call the audio component ref and stop it in the stop rain event

[trim matrix]

Gotcha

?

[icy dragon]

What function? 🤔

[fiery glen]

is that a blueprint interface?

[trim matrix]

Yeah

[fiery glen]

blueprint interfaces are so cursed...

[icy dragon]

I think I saw this error when dealing with C++ inherited functions, never BP interface function calls 🤔 🤔

[fiery glen]

are you calling it in a constructor?

I'm honestly not sure how that error can be triggered from a BP function

[trim matrix]

I was going to put it here so I could link it to the "stop" node

This is the ThirdPersonBP

[round moth]

anyone know how to let you use your mouse when you bring up a menu but not when it goes away

[trim matrix]

My bad, my dumbass

I needed to do "implement function"

Not just drag it in

[icy dragon]

Set Input Game and UI?

[fiery glen]

watch the video I linked you

[round moth]

oki doki thnaks

cause i went to the first person template

which fixed the movement problem

and then i got the widget

so it was great

then realised i couldnt use it lol
