blueprint

[keen wedge]

...always happey to be anyone's challenge! 😄

[gentle urchin]

Bg, ground and bird stands still

[keen wedge]

blue?!

the little angle lines on that grass move on the app I have... I used a material originally (to save the code) but I couldn't get the speed on the Panner to match the speed of the moving objects precisely... so changed it and went with this... I can control the speed of pipes/ground with the gamemode variable now.

[gentle urchin]

More flexible i suppose 😄

And very little cost !

[keen wedge]

yeah... I'm sure there's a way to convert the UV speed calcs so that I could still use a material, but honestly... this was quicker in the end...

Right... I'm dropping out again, making sure I'm not your excuse not to make some progress! 😉

[gentle urchin]

No worries, plenty of others to be my excuse ! 😂

[green lynx]

Hey guys ! I'm just getting to grips with unreal engine 4 as a sound designer, I was wondering if someone here can help me troubleshoot an issue im having where my sounds stop playing when im on a particular surface ?

[gentle urchin]

What sound? Footstep?

[green lynx]

car tire sounds

[gentle urchin]

Sounds related to physical material

Or the lack thereof

[green lynx]

yeah i did think that, however on the said surface, which is a bridge it stops working unless im on the borders of it where (the sidewalk basically) then it resumes working whilst im on there, but all the materials have an assigned physical material

[gentle urchin]

And where you're triggering the sounds support the give physical material?

[green lynx]

the thing is the tyre sounds themselves are actually not related to the physical material

[gentle urchin]

Like, its an existing material ?

[green lynx]

like they have nothing to do with it, they are supposed to play regardless

which is why this is as confusing for me

[gentle urchin]

Right but the sound should change depending on material?

Asphalt sounds different from dirt

[green lynx]

not the actual tyre flapping sound, ive got other layers that change

[gentle urchin]

If its not that, then I dont know

[green lynx]

would it be ok if i upload a screenshot

[gentle urchin]

But it really sounds related

Ofcourse ^^

[green lynx]

this is linked to a sequence node that comes out of event tick

i am using wwise but it works perfectly fine with wwise + ive got the exact same system for the engine and that works perfectly fine regardless of what surface its on

[gentle urchin]

Not familiar with this setup,

But this is not directly whats playing the sounds

I think you must inspect the ak game object?

[green lynx]

the post event is essentially play sound at location

it just posts the event in wwise which then plays the sound

[gentle urchin]

And its just a single sound que thingy?

Usually theres some swotch on phys mat but..

[green lynx]

its a looping sound

[gentle urchin]

I only played with ue4s example project

Which has it based on the phys material

[green lynx]

this is one of them ! this is on the vehicle game

would it be ok if i show you when the problem occurs in the voice channel ? i can stream and we dont need to voice chat if youre not comfortable about it we can just write

[gentle urchin]

Making dinner , so cant right now 😂

[green lynx]

fair enough haha

[gentle urchin]

I remember struggling with sounds on it aswell when i added dessert

And atleast for me it was a physical material issue

You had to add support for the different ones

[green lynx]

hmm it only shows me two materials on the bridge and both of them ive added a material to, is it possible they consist of multiple ones or something

here is the exact same setup im using for the engine and it works perfectly

i will have a look now

yeah ive attached a physical material to everything related to the bridge now and it still wont work

[gentle urchin]

Have you found where it actually playes the sound?

[green lynx]

yeah one moment

[gentle urchin]

Also id expect engine to not change sound based on physical mats^^

[green lynx]

so it plays when im on the sidewalk and it stops when im on the actual street

[green lynx]

yeah but the sounds im talking about in particular are literally just tire friction sounds which i want to keep the same as i've got other skid sounds that change based on the material

[gentle urchin]

Exactly !

[green lynx]

and its weird as the material switches and everything its just that all the sounds + the skid sounds that are influenced by the material ONLY play when im on that part of the bridge

[gentle urchin]

Can you show a screenshot of the "play sound" part?

I cant recall wherr its located

I may have some time in a few hours to dl the project and take a look

[green lynx]

not sure what you mean, in the blueprint ?

[gentle urchin]

Yuss

[green lynx]

yeah for sure that would be super helpful if you could

[green lynx]

1 sec

the play sound is post associated ak event

[gentle urchin]

Theres more to it than that for sure

[green lynx]

so the way it works is i create events in wwise, which are then put into ue4 and that event you can, like an attenuation literally drag into the scene

heres how an event looks like

[gentle urchin]

Oh fancy !

Never heard about wwise

Looks like a nice toolset!

[green lynx]

its really good yeah ! much more audio friendly and alot more possibilities

[gentle urchin]

So how does it differentiate what sound to loop? RtpcValue?

Or is it like a static singular sound?

Always the same, like an engine sound?

[green lynx]

no so let me explain

[gentle urchin]

Sorry about all the questions 😂

[green lynx]

not at all ! you need to understand to help haha

[gentle urchin]

Im really noob about sound setups

[green lynx]

the event ive made in wwise has it programmed in there that it will be looped, which sounds to loop and the RTPC value node controls a variable which influences the volume

a game parameter in wwise lingo

[gentle urchin]

Right ok so like a material scalar parameter node

Cool cool

[green lynx]

i believe so

so the forward speed controls the rtpc (volume) and then it posts the event (plays the sound which programmed to be looping)

[gentle urchin]

The event is only posted once ever tho

If thats by intent then all good

[green lynx]

yes it is cause its a loop so it will just keep coming in and out depending on the speed as ive programmed the volume to go to 0 on low speeds

and it works well and good everywhere else on the map besides on the bloody middle of the bridge 😄

like heres the weird bit right, as soon as i come off the bridge the tire loop resumes playing ?

im just lost 😄

[gentle urchin]

So like

What exactly triggers when one enter the bridge...

Is there some special attenuation applied on the bridge ?

Or whatever its called

Some trigger volume there

[green lynx]

no, its a completely different part of the blueprint and its in no way related to the sound in question

[gentle urchin]

So the sound in question is not affected by regular ue4 sound settings, is that correct?

Sound mixer is what i was looking for i think

[green lynx]

im not sure man it sohuldnt be but its my suspicion that it might be somehow

[gentle urchin]

I assume thats why you handle volume with throigh the rtpc...

[green lynx]

yes

[sleek wadi]

Sorry if this is the wrong section to ask this. I am going through a tutorial on building crowds and the video at one point copies the location of a Target Point to paste into the target location of a character under Default. However, when I use 4.27 the Defaul seems to be missing and I am wondering if anyone happens to know where I can find this setting. Thanks!

[faint pasture]

Does your dude have the TargetPoint variable?

[void mortar]

Hello I'm trying to find someone who can combine to asset packs from the marketplace into a single character blueprint or creat a custom blueprint based on the EA game Anthems combat and flight mechanics

[slow pewter]

Merging is Easy if u understand the Basics, just learn it

[sleek wadi]

I got the target point but not sure where to find the variable

[faint pasture]

Check if your dude class has a variable called TargetPoint

[faint pasture]

#freelance-jobs And have about $10k minimum ready to spend if you want someone decent.

[void mortar]

Anyone paying 10k to merge two blueprints together is an idiot

[faint pasture]

Anyone thinking they'll get a polished combat system like Anthem for even that cheap is one as well. Slapping a couple asset packs together is one thing, making something decent is another.

If all you want to do is merge a couple packs, just do it yourself. You need to learn how the engine works anyway.

[wicked magnet]

Has anyone come across any good tutorials/guides on switching between characters using the Player Controller? I've been kind of surprised by how many guides I've seen use kind of janky methods like using the level blueprint, or switching characters within the actual character controller code, vs managing everything via player controller.

[faint pasture]

Switching between different pawns that already exist or swapping your pawn out?

Something like jumping between pawns is just as simple as calling Possess on them

If you need a "swap back" mechanic just keep track of MyPreviousPawn in your Playercontroller

[wicked magnet]

Switching between different pawns that already exist, including, yes, a "swap back" method.
Sorry, while I've seen examples using Possess, I'm unclear on how to reference the pawns in Player Controller. I only know how to cast to a pawn using Get Player Controller, but inside Player Controller I get '[pawn] does not inherit from Player Controller

[faint pasture]

PossessPawn(PawnToPossess)
{
MyOldPawn = Self.GetPawn();
Possess(PawnToPossess);
}

PossessOldPawn()
{
Possess(MyOldPawn)
}

Add your IsValid checks etc.

Just need a variable MyOldPawn of type Pawn on your playercontroller

[wicked magnet]

Is there a blueprint equivalent to GetPawn()? I tried Get Player Pawn but that seems incompatible with MyOldPawn.

[misty tulip]

Hello Everyone. I am having trouble solving a problem and I hope someone can help. I've asked on reddit and the unreal forum with no responses so far.

I am working on a security system blueprint setup. Currently I have line traces check if the player is not occluded behind any objects.

The line traces are only supposed to check when I’ve entered the collision mesh (Vision Cone). It checks every quarter second.

Here are the blueprints for that.

https://i.imgur.com/KMp1fDy.png
https://i.imgur.com/yBdXoA0.png
The Vision Cone is a static mesh I created in blender. The problem I am having is the line traces fire correctly when this static mesh is using a simple collision but its not the right shape.

Simple Collision Example

https://i.imgur.com/knLEpdn.jpg
When I switch it to use complex as simple collision the shape is correct but the traces only fire a few times when entering the mesh and not consistently when inside like it would with the simple collision.

ComplexCollision Example https://i.imgur.com/WXtorUU.jpg
Does anyone know what could be causing this?

Here is a video of me demonstrating what’s happening. The beginning of the video I’m showing it not working and then the second half I demonstrate it working with simple collision.

https://www.youtube.com/watch?v=gAoeHNq0cPA

[wicked magnet]

Like this is essentially what I'm going for, but I just don't know how to make these kinds of references to the player characters outside of the level blueprint.

[odd ember]

what do you want to do, in non technicalterms

[mossy mist]

Hi I have a instanced static mesh (a torch) and i want it to replace itself with a full actor with lights when the player gets close. How could i acheive this?

[sturdy herald]

delete/hide the static mesh and use SpawnActor node?

[faint pasture]

Yeah just get possessed pawn in the PlayerController

Self -> type in pawn and you'll find it

@wicked magnet Are you trying to do a Lost Vikings style thing?

[mossy mist]

buts its an instanced static mesh

[sturdy herald]

Create an actor blueprint with the same torch static mesh.

[trim matrix]

Hi, I'm a semi-new UE4 user, I'm trying to reduce the error margin of my ground pound move at low-frame rates that shoots a sphere cast under the player every frame while the player launches down, any way I can use delta-time properly to make consistent results across different framerates?

If anyone could help me find a solution I'd really appreciate it.

[earnest tangle]

What exactly is the trace for? Applying damage or something?

[bold phoenix]

Hey ! I'm trying to spawn an actor under certain conditions but for that i need to access info about the actor before it is spawned. Is there a way to do that with tag ? Or by adding tag on a class ? I just need a lead to know where to search, because I haven't found anything yet

[earnest tangle]

What information are you trying to get from it before spawning it?

[bold phoenix]

For example if he needs a support

[earnest tangle]

Some things will be available if you have the class, and use the get defaults node

[bold phoenix]

boolean

I have the class

[earnest tangle]

If it's a variable on the actor class, get defaults would probably have it available

[bold phoenix]

This is my actual code but it doesn't work because the actor has to be spawned already for the interface to work

[earnest tangle]

Yeah the only way to pull info from an actor which does not exist at all is get defaults

[bold phoenix]

I'll try that thank you !

[earnest tangle]

It won't give you everything but it will give you some, so YMMV :)

[trim matrix]

when the player hits the ground they do a bounce where the player is stunned for a second

the trace is for impact

[earnest tangle]

Can you not detect when the players hits the ground just from collisions, without tracing?

[trim matrix]

hm I suppose, idk I'll have to see

[earnest tangle]

That would probably be the least annoying way of doing it

Since if it moves it should more or less move in a framerate independent way, and UE should be able to detect when it hits the ground, and do any depenetration and such if needed

For a trace based approach, if you want it to be consistent across framerates, you would manually have to ensure you always perform the same number of traces, so for example if the distance moved on high fps is 10 units per frame, you'd have to make sure that if the distance moved is say 20 units, you perform an extra trace at the appropriate location

[trim matrix]

thanks I'll try your suggestions

[faint pasture]

Does your pound happen over time or at a specific time?

That is, does it have a duration?

[mossy mist]

no its an instanced static mesh

how do i delete / hide it

[trim matrix]

It's overtime

[mossy mist]

based on where the player is

[faint pasture]

Please explain how exactly it should behave. Input happens then what?

[trim matrix]

It works almost exactly like any Mario game, when activated in the air the player freezes for less than a second then descends downward at a specific speed the sphere trace starts casting when moving downward and is supposed to register a hit when it collides with the ground which then triggers a small bounce @faint pasture

[earnest tangle]

Yeah that definitely sounds like a regular collision as a result of movement would do it :)

[faint pasture]

Yeah use the capsule hit event for sure

No need for trace. I'd do a sphere trace on hit to know who to apply damage to or whatever but the movement mechanics do not need any tracing

[trim matrix]

Okay, thanks a lot everyone

[faint pasture]

"Pounding" is a state that you go into when you start the pound and exit when you hit something. When "Pounding" you are falling with no air control and when you hit something, you check if you're "Pounding" and apply DMG in area, spawn particles etc. In production a ground pound might look like a movement mode in the CMC but that's more complicated.

[faint pasture]

@misty tulipI wouldn't use a cone. Use a sphere and check the angle by dot product

Character is visible if they're overlapping the sphere, Dot(Normalize(PawnLocation-CameraLocation), Camera.Forward) > SomeNumber, and the line trace can reach them.

It's basically a distance check, angle check, and visibility check in that order.

[misty tulip]

Can that be set up in a way so if I adjust the fov or aspect ratio of the camera component in the security camera it will also adjust the dot product?

[faint pasture]

If you are using an actual camera component then there might be a frustum check you can use

https://forums.unrealengine.com/t/perform-frustum-check/287524/2

That will make it exact

[misty tulip]

Ok I'll have a look at that. Currently I just have the line trace max distance as the a distance check but your way sounds more uniform. I'm new at this program so I imagine a lot of the ways I do things will be an ineffective way of doing it.

[faint pasture]

I mean it all depends on how many cameras are around and how many targets they care about seeing etc

[misty tulip]

Currently I'm only interested in it seeing the player

[faint pasture]

Is it like 3 cameras or 300?

[misty tulip]

I'd like to develop some blueprints that will allow many cameras

[faint pasture]

K then I'd do it like this.
BeginOverlap -> SetOverlappingPawn
EndOverlap -> ClearOverlappingPawn

On tick / timer -> if OverlappingPawn is valid -> Angle Check -> Visibility Check

You can do the frustum math yourself in the angle check, just transform the pawn location to local space of the camera component and do the trig. I'd dig around and see if there's a nice frustum test tho.

[misty tulip]

Yeah that makes sense. I don't want them checking if the player is nowhere even near in vview.

Is frustum a rectangular projection out from the camera viewpoint?

Thanks for your help btw

[faint pasture]

Yes, it's the 3d shape the camera can see

[misty tulip]

Ok yeah I just googled should have done that right away haha

[faint pasture]

There might be a function to convert a 3d point to clip space or whatever the camera space is called, that'd be a great shortcut to check if it's in it

Is this in 3d or 2d?

[misty tulip]

3d

[faint pasture]

ye thats a bit trickier. My game does a LOT of 2d visibility stuff but nothing in 3d

[misty tulip]

For aspect ratio I could just multiple the relative width of the frustum. So a 4:3 ratio is 1.33, I could maybe multiply the horizontal axis by 1.33

Then set that up as an adjustable variable

[faint pasture]

Something along theses lines is the key i think

I'm not sure what the 3 matrices mean really but I think the trick will be some function of the view and the position you're checking.

[misty tulip]

Ok Ill have to read up on these nodes

[faint pasture]

http://www.codinglabs.net/article_world_view_projection_matrix.aspx

[misty tulip]

Thank you!

[faint pasture]

This looks to be headed in the right direction

[misty tulip]

Yeah it does. It's way less hacky than using an actual cone geometry for collision

[faint pasture]

The cool thing about this approach is its all driven by the camera properties. Make the camera have a different FOV and it'll all follow.

[misty tulip]

This would also be great for culling anything out of bounds. Many uses for this.

[faint pasture]

If it doesn't work, try transforming the world position in question to the local coordinates of the camera component (Inverse transform position), then you can do Find Look At Rotation and check the yaw and pitch vs FOV angles.

[novel jungle]

Hi guys I was hoping someone could help me with this. I have to enable use controller rotation pitch on my character as I need the

pitch to be replicated

however now when I look up and down the entire mesh rotates and it wont let me lock the rotation

[grand valve]

im guessing what you want to do is replicate an aim offset, like where your character is looking up and down?

[novel jungle]

yes exactly

[grand valve]

You dont have to use controller rotation pitch, because that turns you into more of a spaceship :), you just need to store your pitch as a replicated variable

[novel jungle]

because its controlling another actor based on where its looking, however when use controller pitch is disabled, clients arent able to aim up

wait how would I do that

[grand valve]

not sure of the specifics in your situation, but usually you have a node called add pitch input when you look up, but that only controls a camera attached to your actor

[novel jungle]

so basically im using the world rotation of my character camera who is the insigator. Then in another pawn, im using getinstigator->getworldrotation to find a forward vector

but inside the other pawn, when I do getworldlocation, the client gets it correct but the server doesnt, so It doesnt replicated the pitch

[grand valve]

can you use the world rotation of your character camera and cache that value to a replicated variable somewhere?

[novel jungle]

So i couldnt do that, but i've now realized im just stupid and I can use getcontrolrotation of the insigator

ty so much tho that actually helped me figure it out lol just talking through it

[grand valve]

ya! was just gonna say, control rotation is what you want i think, np 🙂

[faint pasture]

Double check, as I'm pretty sure control rotation isn't available on other clients. You probably want BaseAimRotation

That is, Client A can't see Client B's control rotation as they don't have Client B's PlayerController available.

[novel jungle]

yes i did run into that issue let me try baseaimrotation

that worked beautifully thank you

Is where is BaseAimRotation stored?

[faint pasture]

I think it's on the pawn.

It's like the pawn version of control rotation

Really poorly named tho

[novel jungle]

ty

[covert karma]

Can someone help me figure out how to make a macro that detects if an input is pressed three times please? I followed this tutorial but can't figure out how to modify it to include a third button press. https://youtu.be/GziaROF2Z7g

[foggy escarp]

The multigate gate chooses a new output every time

Macros wouldn't work for this entirely because of how they are copies of logic reran. They would be effectively ran the first time every time.

But you could use a variable or just do it in the graph

If done in the graph it would be pretty straight forward.

By having a delay you can reset the gate if the button isnt pressed in quick succession.

[covert karma]

Very helpful thanks!

[unborn compass]

hmm anyone have a way to get one of 7 widget components based on an input from a custom event

ie i have "element1" "element2" etc and I want to set their color based on the input of a custom event

is there a way to append like "get element" + variable

i guess switch on int will work but its gonna be pretty redundant

basically is there a way to do this without just repeating "set brush color" 7 times

[gentle urchin]

Select

Or an array of elements

[tame hearth]

Is there a way for a widget like a button to know which widget interaction component (pointer/virtual user index) triggered its events? (hover/clicked)

[trim matrix]

I wonder how an object can spawn in the air (off-camera character) and fall to the ground in a certain point. Any help?

[icy dragon]

Simply spawn the actor and enable Simulate Physics? What's the hold up?

[trim matrix]

with simulate physics the object falls to the ground into a random point. I always want it to be falls in a certain point.

[icy dragon]

Although you mention character, the movement component should already handle the gravity

[icy dragon]

Check if actor location in Z axis equals a number, then disable gravity?

[willow yacht]

you can lock position and rotation to prevent movement on certain axis

[noble cargo]

anyone have an idea why when i "use" an item from my inventory(putting my sword on my character, but not equipping) it spawns over my character? Here's a quick video. Following a tutorial, and ive went back 3 videos and im not seeing anything ive done differently to make this happen. https://youtu.be/Enr9M0k1Fbg

[icy dragon]

Note that Character Movement Component has its own "physics" handling.

[icy dragon]

Show code and the issue in action.

Also do not crosspost without prior redirected.

[tame hearth]

Actually my use case is that i want the correct motion controller to vibrate, left controller vibrates when it was the one that triggered the widget event. what i can think of would be to use the widget interactions's onHoveredWidgetChanged to set a call back on the widget, any easier way?

[noble cargo]

i apologize. Which code would you like to see?

[willow yacht]

Collision Enabled settings need to be set to Physics Only or Collision Enabled (Query and Physics)

[noble cargo]

Im not 100% sure if this is where my issue is, but here is the blueprints for the "spawngear" funtion. https://blueprintue.com/blueprint/nzr07-js/ . Video to the problem https://youtu.be/Enr9M0k1Fbg

[remote belfry]

Does anyone know of issues with save game slots and map variables? OR if there is something specific I need to do to get save game stuff to work with a map variable? I'm trying to use a map do (Keys: String: Value:int) to save player inventory, but it's the only variable I can not for the life of me get to stick with a save/load system. Everything else works fine.

[gentle urchin]

Isnt there some thing about TMaps not serializing, thus not possible to save directly?

Nvm it appears it should be possible

Atleast in cpp

[remote belfry]

balls

lol

[gentle urchin]

Cant you just convert it to arrays and save it 😄

[remote belfry]

lol

[gentle urchin]

Extra step but oh well

Revert on load 😅

[remote belfry]

I'm probably going to have to do something like that in general.

I jsut wanted to use a map bc its easy to stor item name as a string and then count as an int and be done with tit. lol

[gentle urchin]

Usually inventories are arrays due to multiple identical items, which a map dont support

[remote belfry]

Yeah my stuff is pretty simple. I dontl have to worry abotu all that stuff.

OR typing apearently.

If I could have it my way It would just dump out a csv and call it a day.

Thanks though

[gentle urchin]

You can !

Just.. a few more steps 😄

[remote belfry]

lol

Then off i go!

[remote belfry]

Thanks for the rubber duck. I compleately forgot there are free CSV and file management plugins.

[odd ember]

in cpp everything is possible. save to slot functionality in BP is much more limited

[keen wedge]

Can someone sanity check my broken brain please...

I have a sprite - 1px per unit...

I want it to bob up and down on the spot moving 6px up, then 6px down... over 1 second (half a second up, half a second down there abouts) thus, that would be 6 units up and 6 units down...

I've created a Timeline, float track, added keys as follows;
0.0 = 0
0.25 = 6
0.75 = -6
1 =0

When run, the bobbing up and down is working, but its moving waaaay farther than I would expect... if I divide the value by 10 (0.6) it seems closer to what I want...

Any thoughts as to where I'm going wrong?

[odd ember]

probably your conversion. 1 unit is usually 1 cm. that's a pretty big pixel

[keen wedge]

I've just left them all set to 1px per unit for now... everything is in relation to itself so as long as all the sprites use the same it should be ok shouldn't it?

[maiden wadi]

It's the addition.

Half of the timeline, you're adding to the Z value, the other half you're taking away from it. You're not going up 6, you're going up a lot more.

[odd ember]

try with a lerp instead

yeah that's true, you're going up 6 per tick

[keen wedge]

...but thats what I want to do isn't it? e.g. up by 6, then down by 6.... I assumed the Timeline was giving me the fraction of the value I wanted each tick?

[odd ember]

but I would also recommend that you use a lerp instead regardless. it's the best way of ensuring consistency

have your float track be only use alpha values from 0..1

and use that to lerp whichever value you want

plus you can use one track for multiple different lerps at no extra cost

[keen wedge]

..would the lerp approach give me a smoother curve too? so its less noticeable on the changes in direction?

[odd ember]

well it would be a linear interpolation from A to B. so it's not really dependent on the lerp itself but on how you structure the curve. you're essentially doing an animation curve right now

[maiden wadi]

It's not. that will just return the actual number from the timeline each frame. This is why most timelines are 0-1 values.

[keen wedge]

bit lost with that... ?

[keen wedge]

...so each time this runs I just get "6" out, over 1 second?

(or minus 6)

[odd ember]

as far as I have understood from animators you can do a smooth movement by making it quicker and allowing the motion to pause at each end point

but I'm not an animator myself

[odd ember]

you get 6 per tick

so if your framerate is 60, you get 6*60 = 360

[keen wedge]

..so how will changing to to 0..1 help? wouldn't I just get 1 per tick then?

presumably I'd need to wire in delta seconds?

(or does the lerp do that?)

[odd ember]

if you're using a lerp it will linearly interpolate the two values. so it will consistently add or remove values to reach exactly the values you need to reach in a linear fashion

[odd ember]

no, the lerp handles all of that.

[shell smelt]

Um, I got a little issue over here

[maiden wadi]

This is your current timeline over the course of about 0.6 seconds.

[odd ember]

heartbeat?

[keen wedge]

so, if the timeline is just giving me a value of 1 ever tick, why not just put that in the Tick event? thought timelines were supposed to be better/preferred over tick? I assumed the float channel would give me part of the value between 0..1 as it fired the Update execution pin... which I assumed would happen many times... and then eventually, by the end of the full 1 second, I'd have the full value etc..

[shell smelt]

When I tried to set this up, the character's camera spin around like there's no end of the line 😅 and then, while it is rotating, I can't move the character at all, except IF I move that Mouse Y.

The original concept was to make the whole character follow the camera while its rotating but it never stop rotating.

[odd ember]

they are, you have much more control over a timeline than over tick. you don't need to consider delta seconds. all you need is a lerp and a float track between 0..1

but everything in the game runs on tick

[maiden wadi]

Personally. I'd ditch the timeline entirely and just do a Sinewave math equation for this.

[odd ember]

everything

it'd still need to be updated

[maiden wadi]

It's a flapping animation which is constant. Should probably go on tick anyhow.

[keen wedge]

ok, will rewire it now and see what happens, thank @odd ember and @maiden wadi ...

...the sinewave was actually what I had pictured in my mindseye... but my mindseye is far better at math than my mind... so wasn't sure how to do that... thought I could push a curve asset into the timeline to achieve it..

the actual animation is being managed by animation... this is just on the main menu, this little annoying bird moves up and down to look like its flying before the game begins...

(this little bird is a pain my arse)

I was wondering if I could have done the up/down movement via animation also, but couldn't see anything to manage "movement", without creating separate sprites... which doesn't work for me for another reason...

[odd ember]

I personally like separating stuff like this out into timelines as it's easier to manage. BP tick can get flooded quite easily

[keen wedge]

wired the lerp up, presumably wrongly, he's now still moving the same amount of distance, but has a kind of bounce..

lerp was used with values of 6 and -6

[odd ember]

did you change the timeline to be between 0..1?

[keen wedge]

yep

[maiden wadi]

Depends on the classes. I don't like extra components and I collapse major tick areas into functions. My tick is usually nothing but Tick->SomeFunction->AnotherFunction->SomeThirdFunction

[keen wedge]

1 as in "1"... not "0.1"

[maiden wadi]

I also don't have access to timelines a lot. 😄 I work in widgets a ton.

[odd ember]

can you show the new code?

[keen wedge]

again, values of 0.6 and -0.6 seem better, but the lerp is giving it a "bounce" effect that wasn't there with the timeline previously...

?

[odd ember]

that's fair. for actors I think timelines are invaluable

[maiden wadi]

Still amused that tick as a function is 'slightly' faster than tick as an event.

[solemn lintel]

I have a question/issue that is somewhat related to all this if you don't mind me butting in? 🙂

[odd ember]

and also show the timeline curve that you have. the curve itself should also stay inside 0..1

[odd ember]

go for it

[raw orbit]

hey guys, anyone know of a way to get whether an action input key is down without directly linking it to the inputaction event? or do i need to basically create a separate boolean

[solemn lintel]

I'm working on a top down shooter and I have a camera that slightly follows the cursor. I'm looking for a way to slow this down a bit, probably lerping it's previous location with its new one, however it runs on tick and I'm not really sure how I'd go about this.

[odd ember]

right you're still adding them. as stated previous that means you're adding 6 or -6 per tick

[keen wedge]

when I've seen that done before, its usually been with a bool being set... e.g True when Pressed, False when Released....

[keen wedge]

oh... what should I be doing in that bit then?

multiplying?

[earnest tangle]

Store the target position in a variable and lerp the current position towards it on tick

[keen wedge]

ooooh... where it is "+6" as A and then where it is "-6" as B ?

[raw orbit]

mmm yeah, i think ill resort to that as well, just being a cheapskate and seeing if i could get away with as few variables as possible lul

[shell smelt]

Ooh, I tried to make that but it ends up with unlimited rotating 😭 - sorry to ping you

[solemn lintel]

on tick as in delta seconds or.. what's the lerp input?

[earnest tangle]

maybe try using VInterpTo if you store it as vector

or VInterpToConstant

[solemn lintel]

No worries, I had a few issues as well but I think it's close to good soon

[shell smelt]

2 hours trying to make those, but it end up like this

[solemn lintel]

Wow, I had no idea these nodes existed, thank you! I'll try it out immediately

[earnest tangle]

👍

[shell smelt]

Ah.. It became mkv files..

[odd ember]

actually it should be working correctly, or my math skills are broken as well. it's scaling the values through the lerp, so at 0.5 it would add 0

how does it look?

[keen wedge]

its looks b0rked...

I've changed it to this...

I set the StartPosition in BeginPlay... at the moment it moves up, then "snaps" back to the bottom...

so, no longe "bouncing", but now jarringly snapping...

[odd ember]

that's consistent with the curve that you've shown

[keen wedge]

the distance however is about 6px... so that part is resolved 🙂

thought I had to have a 0..1 curve? e.g. straight line?

[odd ember]

if you want it to go down, you'd need to move the curve back down to 0 at a third point

so 0..1..0

[maiden wadi]

This is far too complex for a thing sitting on the main menu for visual. 😄

[odd ember]

if you just loop 0..1 it'll snap back down

nah I don't think so, it's no more or less complex than tick

[earnest tangle]

Oh hey look I found a way to create events inside function graphs :P

[keen wedge]

..that is what it is supposed to be doing

[odd ember]

@keen wedge

[earnest tangle]

It actually lets me compile this without any errors or warnings... for some reason

[odd ember]

spoopy

[earnest tangle]

It seems to be as if the EndStun event doesn't exist at all as far as the BP is concerned

[keen wedge]

getting increasingly confused with the time line now... I thought earlier we were saying that every tick I'd just get the value of 1 out... why add a zer0 at the end with the 1 at 0.5, if I will never see the 0.5 value coming out of the timeline when it Updates?

[odd ember]

the curve does what you tell it to do. you set the curve to go from 0 to 1, but never back down to 0 again. so when you start it goes from 0 to 1, and then snaps back to loop again from 0 to 1

[keen wedge]

..the 0..1..0 thing works... just don't understand why 😄

[keen wedge]

so when the Update exution ping is fired... and the value from my Alpha float track comes out - is it ever a fraction of 1 like I originally assumed?

[odd ember]

yes, you can even see the exact value if you hover over the curve inside the timeline

also @maiden wadi is right in that -6..6 is a movement of 12 px, not 6

[keen wedge]

lol... thats how I thought it worked when I posted originally... so the main issue with what I had, I think, was purely the addition node etc?

[keen wedge]

I have the start position +6 for A, and then just the start position for B, so that should only be a movement of 6px now..

[odd ember]

yes. but again, you made the timeline loop without accounting for how you wanted it to loop. if you ask the timeline to loop it's just going to update until the end and restart, with no regard for what you have in your curve. if you want it to look like it loops perfectly, your start and end values have to be the same

[keen wedge]

they were originally, I had the +6 at 0.25 and the -6 at 0.75 with 0 at 0 and 0 at 1... but I can see how that would have been a shift of 12 now...

this is what its doing now...not quite as nice as the original, but close... (ignore the b0rked UI... tomorrows problem) - and thanks again both for the help (@peak wedge / @maiden wadi )

[keen wedge]

only just saw this... sorry I didn't reply!

[odd ember]

you can adjust the curve to be more smooth inside the timeline

[maiden wadi]

All good. 😄

[odd ember]

if you click a curve point and press 1 that's going to give you a smooth auto curve

[keen wedge]

will give it a whirl now..

[maiden wadi]

It does.

All timers do.

Making a time dilation ignoring movement component was fun. 😄

[keen wedge]

did it on 3 of the keys, looks better 🙂

[maiden wadi]

Took me a little bit to realize that motion blur is totally screwed with time dilation. Had to disable it. 😄

[odd ember]

you can also move the points further apart so that the whole cycle is longer, that will give each point more weight

[solemn lintel]

VInterpTo was the answer to everything, thanks a lot!

[keen wedge]

I was wondering about that... feels like the 0.5 point could do with being a little wider... will try 2 seconds duration and see what it comes out like

[maiden wadi]

Motion blur is pretty much just a material. It's not set up to ignore it so it's time uses the dilation for effect. Incredibly funny because you end up with a crazy blurry camera only looking into the direction you paused from. If you turn the camera 180 degrees, you leave the range of the material and it's crystal clear.

[keen wedge]

yeah, 2 seconds didn't work... slows it down too much... just held my mobile with it running against my version in UE4 on screen and might need to make it a bit faster anyway... the 1 second thing was based on me recording the app on my phone, then putting that into video editing software to see how many frames it took to move from up to down, and down to up... both parts were approximately 30 frames on a 60fps recording... hence the 1 second duration and 0.5 in either direction thing I mentioned at the beginning... but it doesn't seem to be 100% accurate... (not surprising)

[odd ember]

it's up to you and your needs. I'm just telling you what you can do expand the time at each point. you can scale that up or down collectively

[keen wedge]

Thank you 🙂

[gentle urchin]

Cant you just overlap with custom time dilation? 😄

[maiden wadi]

Sort of did. I just subclassed the FloatingMovementComponent and returned a different deltatime.

[gentle urchin]

Ah

I thought the custom time dilation variable already did this

[maiden wadi]

Sort of does, but I don't want to keep track of it.

In this manner, the entire game's dilation can be set, and this one movement component can just literally ignore it without having to keep track of when it's changed and update it's own custom dilation accordingly.

Otherwise my time settings need hooks, and this has to hook into it. I have to worry about this updating from load, etc.

[gentle urchin]

Alot of worries, gotcha !

[maiden wadi]

I would just dot product the unit vectors.

It doesn't account for distance. But given you're talking about closeness to the center of the camera's view, that's not really a factor.

It's also much easier to do if you have C++ access.

Because being able to call this on an array is much easier than sorting in blueprint.

ArrayOfActors.Sort([CameraDirection, CameraLocation](AActor* LeftHandActor, AActor* RightHandActor)
  {
    FVector DirectionToLeftHandActor = (LeftHandActor->GetActorLocation() - CameraLocation).GetSafeNormal();
    FVector DirectionToRightHandActor = (RightHandActor->GetActorLocation() - CameraLocation).GetSafeNormal();
    return FVector::DotProduct(CameraDirection, DirectionToLeftHandActor) > FVector::DotProduct(CameraDirection, DirectionToRightHandActor);
  });

Ugh. Discord formatting.

I also did that slightly wrong.

That's a predicate function. It compares the entries against each other. Common to name them A and B or Lhs and Rhs (Left hand side, right hand side)

I'm just more verbose than most.

[eager plank]

Hey everyone, I'm trying to make a blueprint that stop's player movement once a box collision is overlapped followed by a series of audio's playing. Anyone got a clue as to how I could do that? Thanks

[odd ember]

set max move speed to 0 on the character movement component

[maiden wadi]

AND THEN BOOM BOOM KABLAM

[odd ember]

just remember to set it back

[gentle urchin]

Theres a disable movement node

[green lynx]

@gentle urchin i wonder if youve got around to checking the vehicle game out ?

[gentle urchin]

Sadly no, kiddo kept me busy all evening/night/morning so had 0 time at the computer yet :-/

Plus im not sure how much it'd help since you're using wwise? 🤔🙄

The original project doesnt use that does it ?

[left echo]

Noob question - Do I need to do anything special to keep track of each objects variables after I spawn them?

• I spawn objects in my Game Mode
• I move them along a spline using a Timeline (in this image)
• If I press a correct button after certain distance along spline...it changes color
• this works fine for a single object...but if there are multiple...it only works on the most recently spawned

Any idea why??

[green lynx]

yeah it doesnt, i think the problem is in unreal though cause everything works fine in wwise, i can test all the events and how parameter change affects them

• it works everywhere else on the map

[gentle urchin]

And you didnt find any trigger volume was it so?

[green lynx]

yeah

[gentle urchin]

Should be possible to test it,

By just adding the asset

On a different place on the map

And see what happens

Purely for testing ofc, so dont bother about its looks

[green lynx]

yeah ill try that

[mellow folio]

Are the spheres receiving that input themselves?

If so, make sure the input (the red node) does not have "Consume Input" checked on

[lime trellis]

Hello ! I have problem with my character for days and i can't achieve to solve it :

• In my character blueprint, when i animate the character (modular skeleton, each body parts are linked with the "Set Master Pose Component"), i have an offset only with arms.
• But when i set no animation blueprint -> No offset with the T-Pose
• The strange part is that in the Animation Blueprint (or any animation), i havn't any body position problem

If anyone have an idea... 🙂

[left echo]

That was it! Thank you for this glorious tip. I spent some hours scratching my head. And it was this simple checkbox. Woohoooo!

[mellow folio]

yeah so all input events will try to "Consume Input" which means they don't allow anything else (lower on the stack) to also receive it

[left echo]

ah yes, that makes sense. Gathering 1 little bit of knowledge at a time

[eager plank]

How do you play sounds one by one, Im trying to play multiple sounds one after another by just play sound at location and then connecting them to each other. They all play at the same time though, any clue how to fix?

[gentle urchin]

Binding to the sound variable, perhaps theres a 'on completed' node?

On finished? On stopped playing ?

[eager plank]

i tried all

don't seem to be a node like that

[gentle urchin]

Spawn sound at location instead of Play sound at locaiton

[eager plank]

ah ok

and how do i do that

bind even to on audio finished

[icy dragon]

Are you using Sound Cue's Concatenate node?

[eager plank]

i was just using play sound at location node

connected to each other

[eager plank]

it says i need an event to bind it to i believe

[gentle urchin]

create custom event

[gentle urchin]

If there are many of them, i'd consider doing an array and loop based on the callback,

[eager plank]

wait

do i assign audio finished

or bind

[maiden wadi]

Same thing. One just creates a function for you.

[maiden wadi]

On a side note, having dealt with the finicky nature of audio drivers fucking up gameplay logic, I strongly recommend something like actor sequences for this sort of thing.

[eager plank]

it still plays at same time

[gentle urchin]

You need to use the new custom event to trigger the next one

which you'd need to bind to again, to trigger the next one... and so on

[eager plank]

alright

thanks for the help

[eager plank]

ill look into this, thanks for the recommendation

[patent ermine]

I have a pawn blueprint with a spring arm and a camera attached to it. What I'd like to achieve is to add slight random movement to the camera without any user input. This works just fine. However, this will continuously apply movement to the camera. Any way I can clamp the maximum distance the camera can move from its original location? Imagine a camera focusing on a target and just slightly moving around in a random direction, but with a limit to how far from original it can move. Any help is appreciated.

[desert juniper]

there is a clamp node

you can do something like this

just incase you weren't aware, you can right click, and split the struct of both the rotator variable, and the rotator input pin on the AddLocalRotation node

[eager plank]

How do i show a widget on screen for only a certain amount of time, say 5 seconds

[patent ermine]

Thanks for the input @desert juniper . However, if im reading this correctly, this will also continuously add random movement without restriction. The angle is clamped thats being added. However, it wont restrict the movement from the original location. If that makes any sense. I'd still like to have a maximum distance the camera can move from its original location.

[desert juniper]

[gentle urchin]

you should have an "actual" rotation, and a relative offset to that,

restricting it to +/- X from "actual" rotation

almost sounds like a camerashake is better

like... its what it does, is it not? 😄

[desert juniper]

yup, going to have to add a clamp to the actual rotation then
There are a couple other nodes you can play around with
like

if you set instead of add, rotation it should get you closer to your desired effect

[eager plank]

How do i show a widget on screen for only a certain amount of time?

[desert juniper]

what do you want to handle that time?

[eager plank]

what or why?

[desert juniper]

? you're the one asking

do you want the widget to be responsible for removing itself, or some other actor?

[eager plank]

widget responsible for removing itself

sorry i didnt understand question

[desert juniper]

no worries. here's the other way

one sec, while i do widget

[wicked magnet]

Sorry delayed response, but yes based on the wiki entry, I'm wanting to do a Lost Vikings type system where I can switch between different characters that already exist on the map. So I can cycle between them, and control one at a time.

I looked up "pawn" under self and I did see Get Controlled Pawn, but not Get Possessed Pawn. Ultimately though I'm looking to not just find the current possessed/controlled pawn, but also able to cast to each separate one so I can decide which to switch to.
Since this is a little delayed, just re-pasting the screenshot of examples I've seen that do this via level blueprint. I'm looking to do it via playercontroller, instead of dragging each character into the level blueprint to manually assign which to switch to. I want a more flexible system that will work via playercontroller and no level blueprint code required.

[tribal stream]

How would i go about making an object move indefinitely on a certain axis each frame?

[desert juniper]

You're setting the relative location, setting it is overriding the previous location

you are probably looking to add instead

[tribal stream]

yeah, but I was thinking on how to solve it

[tribal stream]

how would I add it?

do i get the world location for the component and add to it?

[tribal stream]

for each tick

[gentle urchin]

Simply add

[tribal stream]

tried that, but it did not go well. I am doing something wrong.

[desert juniper]

when there's a set, there's always an add

[gentle urchin]

the offset you want

each tick

[eager plank]

Amaze

[gentle urchin]

in the desired direction

[eager plank]

i nee dhelp really quick

when i try saving

[desert juniper]

there's a few nodes, if you jut want to move the entire actor, then there's a node for that too

[eager plank]

theres an error with the add to viewport

[tribal stream]

Oh, did not know there is an "add" version of it.

Thanks, will try it.

[desert juniper]

🙂

[eager plank]

This blueprint (self) is not a UserWidget, therefore ' Target ' must have a connection. thats what it says

[desert juniper]

if you're trying to remove it from within the BP, use this one instead

#blueprint message

[earnest tangle]

Is there some easy method of copying attributes from one blueprint to another en-masse? Eg. all matching properties and comps would get same values?

[faint pasture]

Just make each of the 3 pawns a seperate subclass of some base class and at begin play, set your 3 local references in the PlayerController. Then you can swap possession between them at will.

[tribal stream]

Thank you, it's working @desert juniper

[desert juniper]

np

[dawn gazelle]

This needs to be connected.

[tiny frost]

anyone know how to make animations easyer with like swords/guns or what not?

easier*

[earnest tangle]

Easier in what way?

[tiny frost]

kind of like ik but just for the arms

i really dont know what im doing when it omes to skeletons

comes*

[icy dragon]

Constraints?

[tiny frost]

ill look it up im not sure what that is

[wicked magnet]

I realize I'm not 100% clear on a subclass. Is that similar to a child blueprint of a parent blueprint? I also should have specified this could involve looking at different instances of the same blueprint in the map (with each instance having different variables changed) - not sure if that impacts anything.

Ultimately I think I'm just missing the basic fundamental of getting that character reference from within playercontroller. Kind of surprised how unreal's documentation seems to only show the level blueprint method. Thanks again for the patience responding here.

[odd ember]

child blueprint is really a misnomer I'm hoping epic stops using

subclass is the correct term

a blueprint is a class

to be clear

[eager plank]

the widget doesn't delete

[tiny frost]

i think that that is a bit beyond me right no

[desert juniper]

take a screenshot of the entire window

[eager plank]

it wont fit

[wicked magnet]

Okay that is what I thought. Got a little thrown off when I googled to verify and didn't get much in the documentation. But either way, yeah, that is do-able for me to do that with subclasses (aka child blueprints), but I mean I'm just missing the fundamental of getting the reference itself. Normally I would cast to the blueprint, but I am running into issues casting that way from within playercontroller. So looking how to basically get a reference to whatever character pawn is needed.

[eager plank]

theres more to the left

[desert juniper]

not the bp

but the unreal editor window

like just take a screenshot of your entire screen

[wicked magnet]

Did you mean to respond to Henry?

[eager plank]

i believe

[desert juniper]

ah yes, my bad

[desert juniper]

@eager plank

[green lynx]

@gentle urchin i got it working !

a guy i had worked with on a gamejam helped out

[desert juniper]

casting requires you to have an object reference already.
to simplify it, think of you already have a ball in your hand, and you want to figure out if it's a basketball, or baseball, etc. it allows you to narrow down the type of object you have a reference to

as for getting the reference itself, there's plenty of ways to do so. but it depends on your needs

[dawn gazelle]

If you're destroying actor at the end, then none of those timer events will last to execute.

[desert juniper]

how would you ideally like to reference that object?

[eager plank]

i need to destroy actor at the end

[dawn gazelle]

Well you can't do it before those events fire off, otherwise they won't run.

[eager plank]

is there a way

i can instead just disable box collision

[desert juniper]

destroy it after the widget gets removed maybe?

[eager plank]

could i delay it

[desert juniper]

you're already doing the delay here right?

just destroy it after the remove from parent

[main pollen]

I'm trying to rotate my character to my cursor location but he goes full beyblade mode. I think it's because my camera turns with my character as well. How do I make the camera stay and not rotate in it's position while the character turns??

[eager plank]

fixed it

thanks

[gentle urchin]

So what was the issue ?! Well done! 🙂

[odd ember]

I haven't been following your issue, what is it exactly?

[faint pasture]

You'd make a Character BP Class BaseViking, then make 3 subclasses of it (Erik, Baleog, Olaf). Place those 3 dudes in your level.

PlayerController has 3 variables of type BaseViking.

On Begin Play in the PlayerController, Get actor of class Erik, set ErikRef, get actor of class Baleog, set BaleogRef, get actor of class Olaf, set OlafRef.

There. Now you have a ref to all 3 dudes and can do whatever you want with them.

[green lynx]

not sure exactly what did it but we did two things - i was placing an object in the viewport of the buggy and i moved it up higher as it might have been an issue with the object being under the bridge when it gets on

object that plays the sound

[odd ember]

ah yeah, this sounds correct if it was the lost vikings query from last night

[wicked magnet]

Yes, I see I've been using the wrong search terms. It's less about the player controller, and more about the right way to get a reference. In my case, what I am looking to do is cast to do something all the lines of Get All Actors of Class - the big picture goal is to be able to cycle through a flexible number of instances of the same blueprint. For example, I could place just 1 character pawn, or 20 instances of the same character pawn, and the playercontroller would be able to cycle through whatever exists already on the map. Nothing is ever spawned.

For now I just want the basics of getting the reference the right way, but that is the goal.

[green lynx]

and the other one, there was an attenuation of some tire sound that wasnt really playing but i just removed that, pretty confident tit was the first one actually !

[wicked magnet]

oh, just saw your second message

[desert juniper]

Yup, Adriel's suggestion is spot on in your case
#blueprint message

[odd ember]

just to add to this, there is a special function you can override in the game mode called SetDefaultPawnFor. Here you can spawn the pawn and parse in information at the earliest time that both player controller and player pawn exists

[faint pasture]

There are a million ways to get a reference and the "right" way will depend on what you're trying to do. A trap gets a ref to its victim when it's stepped on by Event Begin Overlap. A gun gets a reference to what it's shooting by line trace, etc etc.

[odd ember]

if you don't do this you are likely being subjected to race conditions

[desert juniper]

heck, you can even grab the actor from the world outliner, and drop it right into your BP as a reference to the object

[odd ember]

yes but don't pls

don't solve systemic design issues on a level design level

[wicked magnet]

Sorry yeah I sent that message before I saw your second message there. Yeah, I'm not using overlaps or line traces here. Oh! So I somehow missed that Get Actor of Class does work in player controller. Can't believe I missed trying that!

[faint pasture]

Yeah it gets tricky with there being 3 pawns on the level at once. I was picturing him starting with an empty pawn but could def. spawn him in Erik and spawn brainless Baleog and Olaf at Startspot(tagged Erik), Startspot(tagged Baleog), startspot (tagged Olaf) etc

[odd ember]

@wicked magnet

avoids using GetAllActorsOfClass

[desert juniper]

it's perfectly fine way of doing so for quick prototypes. especially for beginners with no real concepts of programming. good way to have them learn and understand references 🙂
but absolutely agree that it's a terrible way to get a reference for anything other then that

[odd ember]

by principle I would never teach someone to do this because it is a terrible habit

[faint pasture]

IDK why TF Epic uses persistent level references in their demo stuff. I have literally never used a level blueprint ever.

[odd ember]

well you're not a level designer

[faint pasture]

Also all my projects are procedural and systemic so never really had a use case.

[wicked magnet]

In my case the pawns need to already be placed in the level before the level starts. Would this work with pawns already spawned?

[odd ember]

why do you need the pawns spawned already? this is the logic that executes when you use player spawn spots in levels btw

[desert juniper]

I'd rather have someone learn a simple solution, and the proper one later, then get discouraged and give up.
I used to teach kids robotics & programming, and learned this at some point.
easier to teach the right way once they've grasped the main idea/concept

[faint pasture]

Quick/dirty way would be to tag one of them for auto possess and just grab references for all 3 at begin play with Get Actor of Class

[odd ember]

strongly disagree with this. if they don't learn it properly there's a high chance of them attempting to push the same behaviors later on. this is how tech debt accumulates.

it's the one place in programming discipline actually needs to be exercised

[wicked magnet]

This is part of a virtual production project where the short of it is that the workflow is that the cinematics team will be placing the actors to be controlled.

[odd ember]

if they can place spawn points instead of actors, it's all good

[desert juniper]

🤷‍♂️
I think it's too much to expect beginners to learn everything the right way from the start.
It's just too daunting and causes so many to give up.
Hell, that's one of the allures with blueprints. Allows for a much easier visual way of programming, without knowing too many programming principals.
Let's be honest, someone that doesn't yet understand the difference between a cast, and an object reference doesn't also immediately need to be taught 'the right way'
What's next? Dependency injection?

[odd ember]

I think if you teach them why, it's a much easier sell than just telling them to do it

[wicked magnet]

They definitely will want to be able to see the characters as they set up the scene. This will be tying into using sequences that references the characters as well.

[desert juniper]

tbf, it's all personal preference on their teaching style. I used to teach, and I personally found it to be way more effective to show the kids the easy way, and then teach them the right way afterwards

[odd ember]

fair enough. doesn't sound like a game friendly workflow, because it goes against how the engine wants to do things

but you do you

[odd ember]

it's pretty safe to assume we're not dealing with kids here

[desert juniper]

sounds like a workflow that can actually get games completed and published rather than stuck in analysis paralysis

[odd ember]

well you're the expert apparently

[wicked magnet]

I agree, especially when the documentation only lists the simpler solution that can end up being a bad practice long term. Can lead to frustration for users as they progress.

[desert juniper]

it's also pretty safe to assume that they don't yet know programming principals, since they don't know the difference between a cast, and a object reference

[wicked magnet]

Yeah this is for virtual production. We're using the game engine just as part of creating cinematics.

[desert juniper]

so a super basic explanation goes a long way sometimes

[odd ember]

and the BP docs do them a terrible disservice by not explaining them well enough, agreed. but that doesn't mean they shouldn't learn them

[icy dragon]

I'm in a strong proposition to teach the principals first

[odd ember]

game development isn't all fun and games sometimes. sometimes you have to understand that it's a job that someone has to do in order for things not to fall apart 3 months later

[icy dragon]

Just knowing BP alone is not exactly transferrable elsewhere.

[desert juniper]

kinda exactly what I'm arguing for here

[odd ember]

but you're not? you're saying "ah f it, just let them do it the lazy way"

[desert juniper]

I'd rather have someone understand where a reference can com from, and that there are tons of ways of obtaining one.

no. I didn't

All I said was something along the lines of 'heck you can even grab a reference from the world outliner'

i didn't even say to do it that way

all I did was show another way to demistify where references can come from

[odd ember]

yeah the documentation is unfortunately super lackluster. it's not really different from other engines, but I think they just never expected this influx of users that are now crying out for more mentoring

tons and tons of autogen pages that say little about what code is actually doing

I can't count how many times I've had to go into individual classes to look at how certain functions are doing certain things just to understand what is going on

[desert juniper]

once again, principals are key, and trying to have someone understand the principals of obtaining a reference are more important that immediately showing the 'right' dynamic way of obtaining one, when they don't even know what it is

[wicked magnet]

Yeah, Get Actor of Class seems like the simple solution here. Since you said quick and dirty, are there downsides to this path? i.e. once I make it the more flexible version where more characters are added, would there be snags there? I was thinking of doing get all actors of class, and adding each instances to an array I could cycle through, or something along those lines, but haven't looked too deeply into it.

Also, about documentation discussion in general - absolutely agree. I accepted a few years ago that UE had less documentation because it was used primarily by studios that knew it deeply and didn't need hand holding, but I am seeing Epic working on beefing up their learning resources, so it feels now in an awkward place where the documentation is better but also.... not great.

[desert juniper]

anyways to sum it up @wicked magnet, i was just trying to show you how you may obtain a reference to an object, since you were confused, and explain the difference between that, and casting.

[odd ember]

GetAllActorsOfClass is a crutch that should never be used. there is always a way that works better

[desert juniper]

GetAllActorsOfClass is perfectly fine

[icy dragon]

Get Actor of Class is like a blunt weapon in domestic violence scenario

[desert juniper]

it's performant enough, and looks through a list of cached classes, instead of the entire hierarchy. no need to get any more complicated then that

[faint pasture]

If you barely know what a subclass is it's fine. For a more extendable system, you'll figure out what you need as you go

[odd ember]

last I checked it did something like n^2 iterations

so I would not call that "performant enough"

and again

teaching the wrong thing

[icy dragon]

Next time you tell me Get All Actors Of Class on Tick is fine

[desert juniper]

lol, no, not on tick
but i HIGHLY doubt the extra complication for someone who barely learned what a subclass is is worth it

[odd ember]

but it is

[desert juniper]

🤦‍♂️

[odd ember]

it really is because you teach them how to fish

instead of giving them a fish

you can't both say "I'm all for principles" and then immediately after say "nah f it b lazy"

that's just being a hypocrite

[desert juniper]

I'm teaching em how to fish, instead of trying to tell them how to grow their own wood, and cut it down, to make their own fishing rod

[odd ember]

that's not at all what's happening

you are giving them a fish

if you don't want to teach, don't

but don't give people advice that puts them on the wrong path because of your own ideology

[desert juniper]

@wicked magnet if you want a simple solution, that WORKS and you'd like to move on, just use GetAllActorsOfClass
If you'd rather spend a week learning the 'proper' way, then go research dependency injection

[icy dragon]

What the fuck

[dawn gazelle]

I have to agree with CE.... It really is like giving them a fish, as you are literally giving them a stupidly simple means of getting a reference.
If you teach someone how to get references in the other methods, it's like teaching them how to use different bait, different lures, different strength line, all depending on what it is you're trying to fish up. 😛

[faint pasture]

Uh uh, somebody better tell Epic it's bad.

[wicked magnet]

Thank you @faint pasture for the video - I understand that. I also understand that Get Actor of Class is considered not ideal - but my understanding is that it's okay if you're not using it all the time? I also know using Interfaces are more performant than Casting, but I know that we're not talking about casting or interfaces in this instance.

I have no problem learning the right method - I'm just saying is that the workflow will require that the actors are already placed on the map, and spawning would not work for what is requested. Just based on how everything is tying into Sequencer, Take Recorder, etc.

[faint pasture]

How do you think the gamemode finds the start spot actors?

[icy dragon]

I guess it's bullshit because it's for virtual production, not for games.

To be fair, I can slack with shitty instructions for cinematics

[odd ember]

interfaces are not more performant than casting. this has been debunked. the only difference between casting and an interface is that a cast retains a hard reference - a pointer - to your object. interfaces internally still do a cast

[icy dragon]

I do think it's pointless if he doesn't want to transfer the skills into game making at all

[desert juniper]

yeah, I think there's TOO much elitism here, that everything has to be done the 'right way from the beginning'

I can almost promise that there @wicked magnet will never see a performance hit from this single time these references have to be acquired. ESPECIALLY since this isn't event for games.

[odd ember]

how is it elitism to teach people the right things from the get go?

[desert juniper]

GetAllActorsOfClass is more than fine in this case

[odd ember]

is it elitism to give your children a good education too?

[desert juniper]

because you're saying that even epic is wrong, and that there's no other way, than your way

that's why

[faint pasture]

They both do the same thing.

[icy dragon]

I know how people from those field behave, they're very very unlikely going to use UE for future game making anyway

[odd ember]

that's not what I'm saying. I'm saying there is a way that sets you up to be successful, and a way that doesn't

[desert juniper]

and failure, since they're beginners, and you're telling them the 'easy' ways are worthless, and they shouldn't ever do them

[odd ember]

and now you're telling me I'm elitist because I'd want people to be more successful instead of less

come now

what is this

[icy dragon]

But to be fair, it's kinda irrelevant if you say it to virtual production people

I know well how they behave

[desert juniper]

those easy ways are there for a reason. better to spend a few mintues, and move on, rather than hours for performance they dont' need

[odd ember]

yes and no. I think if they are going to be working with game engines primarily, they will encounter the same things over and over again

[desert juniper]

classic trap of over-optimization

for literally no reason

[faint pasture]

Both GetActorOfClass and using start spots do the same damn thing, stop nerd fighting and go outside lol.

[icy dragon]

For all it's worth, they can use Blender or other fucking renderer

[odd ember]

it's tech debt avoidance, not over optimization

two vastly different concepts

[icy dragon]

I just only aware of the context after a bit of scrolling up

If this is a game making context, then I spank as well

[desert juniper]

no spank. nerd fight over

[icy dragon]

But with Virtual Production context, it doesn't matter much.

I worked for VP people before.

[gentle urchin]

It's not that GetAllActorsOfClass is gonna be a bottleneck if its only ever used like once (looking at you GameMode),

But if its the first thing people "learn" to use, its gonna be used everywhere...

Atleast that's what I've seen happening over and over and over

[icy dragon]

Though with how linear production people behave, I doubt they themselves will branch out to game development.

If they did, there's a chance they'll hire proper game developers.

[gentle urchin]

Hopefully 🤞🤞

Its like i can already smell the linetrace on tick followed by a get all actors of class to find, cast and compare.... ugh

[icy dragon]

Practically it doesn't matter much when it comes to linear media production
They can use Blender and cook up some Python script for some task automation.

[odd ember]

https://tenor.com/view/ohno-smh-wrong-no-gif-20802904

[wicked magnet]

haha okay so in summary - in this instance, using get actor of class is fine. Spawning would not make a major difference. "Gameplay" in this case would be moving a character around and triggering animations. Very simple. I certainly don't want to take the bad/inefficient route, but sounds like this is fine.

@gentle urchin that was my understanding - like there are obvious Bad Things to do, like use GetAllActorsofClass all the time, or running everything in the event tick, but calling it once to populate an array, or trigger a one time event, seems like more acceptable use based on my understanding.

[desert juniper]

So my major point on this, is
Do things the easy way, and don't overoptimize (but don't do stupid things)
Learn programming patterns, and the appropriate tech as you go.
You aren't working on your final prokject if you're a beginner anyways
If you get far enough into the project where performance becomes an issue, use the profiler to start looking for those issues
You'll naturally start learning the 'proper' way of caching what you need to, and dropping the expensive operations when you dont.

I've probable seen thousands give up by now because they always listen to the elitists who tell them they can't' do some things one way, or another
The people I see that release games typically aren't even in these channels preaching one way or another, they're out there learning 'bad' patterns from youtube, forums, etc. BUT at least they're actually releasing content
I'd rather see someone actually finish a game/project, than give up halfway through it because they learned that a few things they were doing were 'the wrong way'

thanks for coming to my ted talk

[gentle urchin]

Imagine if you then see 368 instances of get all actors of class

And you now need to rewrite 366 of them

To fetch references appropriately

[desert juniper]

if it happens once in the game, especially when the game stats, or is loading, then what's the issue?

if it's happening each frame, then obviously it's a noticeable peformance hit. then take a look into something better

but why spend the extra time and resources on something that isnt' going to matter in the slightest?

again, worried about performance? why not instead just use assembly? why bother with an engine, or a modern language?

[icy dragon]

In my POV, project context matters.

For game development, some Asian parent style spanking is needed to avoid bad code ruining the performance throughout the gameplay.

For linear media production, game engine's realtime rendering is already faster than offline path tracer renderers, a bit of shitty code costing some ms didn't scale up much, as the frame rendering from MRQ will still take more time anyway. In this context, I'll cut some slack.

[faint pasture]

Happens anyway in GameMode. It gets all actors of class PlayerStart.

Something somewhere has to iterate over the actors and find them. It's fine.

[desert juniper]

don't know anything about media production, but agree with everything else. sometimes you need to be strict, and other times you don't. Context is definitely everything when it comes to making those decisions

[odd ember]

hate to break it to you, but most modern languages aren't optimized for games

nevermind the slippery slope argument

[desert juniper]

then just use assembly

[odd ember]

or you know, C++, which is right there and very well supported by the engine

funny that support matters for what you're doing with an engine

[icy dragon]

My daytime jobs deals with linear media production, so I kinda know the inside out and typical behaviours in that regard.

[desert juniper]

I'm not an expert in any language. Just know enough to be dangerous
My project is a cpp project.
it's what I'm most comfortable with. no gotchas there

[faint pasture]

Jai when?

It's looking pretty dope

millisecond compiles too

[odd ember]

ah yeah, one can only hope. but even then there's the question of widespread appeal and mainstream acceptance

no point in using a language nobody wants to work with

if Jai is good I'd love for it to succeed

[icy dragon]

Jai vs Lua

Which one has syntax closer to C

I still have love hate relationship with Lua

[earnest tangle]

the one which has its array indexes starting at 0

[icy dragon]

Wait that's illegal

Shit, I expect it to be less harmful function to create heart widgets

[maiden wadi]

Also. On this note. Do. Not. Ever. Affect gameplay code from widgets.

[icy dragon]

That is way worse than I thought

[maiden wadi]

Widgets should display gameplay values, and call functions on gameplay classes. Affecting their state directly like this is a big no.

[gentle urchin]

Now now, we just talked about this

[stoic palm]

[gentle urchin]

Widgets should only reflect

[maiden wadi]

I think you should just make MaxHealth's default what you need it to be and not affect it afterwards.

[gentle urchin]

Maxhealth needs to change

[icy dragon]

All widget do is just read the values from the gameplay side of things. It should not influence the gameplay code.

Like I was expected it to be.

[maiden wadi]

If you want 3 hearts. Max health's default should just be 12.

[gentle urchin]

Its based on heart cannisters

Or heart containers or whatever

So:
GetMaxHp => return base(3 hearts(12)) + (4*NbrOfHeartCannisters)

[stoic palm]

One message removed from a suspended account.

[maiden wadi]

But yeah. Generally avoid setting gameplay class values directly like this. Try to make setter functions and call those. Your debugging and organization will thank you later.

[gentle urchin]

And refactoring^

Only a day? Damn you fast boi

Nah. Just don't like my PC, so I just start opening up everything all at once. 😄

Editor usually only crashes one out of five times.

Mine crashes 10 out of 10

Due to video card memory (or so it claims)

Haven't hit that one. 😄

Actually dropped money for a decent NVMe and a 5900x for work stuff. No regrets.

And a good payday lol

[echo salmon]

Can i add in GameMode InputAction event ?

[maiden wadi]

You can. But you probably shouldn't.

[echo salmon]

Ok, i cant recognize where is the correct way to place them.

[maiden wadi]

What is the keybind for?

[echo salmon]

open locked door

[maiden wadi]

Sounds more like something triggered from gameplay logic than a player's input.

That's more like.. You press F, interact with some actor in the level and it's interaction unlocks the door.

[echo salmon]

yes

[maiden wadi]

Usually you have an interface set up. Things you need to interact with implment it. Keypads, Door unlockers, Doors, pickups, etc. You press F which is implemented in the player's Pawn class. this does a line trace, probably from camera. Or can do an AoE check, overlap thing in front of the pawn, either way. You decide which actor to interact with and then you call that interface event on it.

[echo salmon]

Ok buddy ty for the info

[main pollen]

How can I stop my camera moving with my character? It's not rotating but when character turns left, camera stays in the same position that is relative to the character. I don't want this.

Or maybe I can set a world camera that is not part of my character's blueprint but follows the player anyway. Is this possible?

[spark steppe]

hard to give a good answer without really knowing what you want

do you have an example?

actually it sounds like it should follow but also not follow

[maiden wadi]

I think they want like a camera on a wagon. Camera follows movement, but doesn't move when character rotates on Z axis?

[main pollen]

Look at Hatred gameplay

something like that

[spark steppe]

cmon give me a youtube link with timestamp (at least)

[main pollen]

https://www.youtube.com/watch?v=k4haxCryhJA&t=166s

[main pollen]

Yes

[icy dragon]

Ah yes, the bastard child of Postal

[maiden wadi]

That's just a standard looking rts camera with a slight interpolation.

[main pollen]

just an example, I dont admire the game 😄

[icy dragon]

Vagrant Story would be a better example IMHO

And I did the camera for my canned megajam project

[main pollen]

FIXED it

[maiden wadi]

I want to do another Megajam. 😦

[main pollen]

just checked "use pawn control rotation"

[icy dragon]

In Vagrant Story you can rotate the camera 45 degrees, and enter first person view

[icy dragon]

My equipment is too weak to do competitive game jams lol

[gentle urchin]

I havnt done one yet 😓

[icy dragon]

I'm looking for more relaxed game jam, without prize at stake

[maiden wadi]

My last project was practically asteroid, except with scanning. 😄

[balmy light]

does anyone know why this particle effect wont reappear after it has been turned off?

[astral epoch]

Particle Effect has finished playing perhaps?

[odd ember]

if it keeps triggering it won't ever fire

[maiden wadi]

Visibility set to false may disable it somehow. Would consider starting and stopping the system instead of visibility.

[odd ember]

the retriggerable delay will block it

[astral epoch]

Seconding Authaer. Do start/stop rather than visibility for this.

[balmy light]

what are the nodes i need for starting and stopping/.?

[astral epoch]

Personally I just use spawn emitter. It automatically starts and, as far as I'm aware, is deleted after its finished. Just keep spawning those in.

Though not sure how performant that is, might be awful if you're doing it literally every frame.

[balmy light]

I tried that but the emitter doesnt move

[astral epoch]

I believe you can attach it to the object?

[balmy light]

i need the emitter to follow the player so the fire enemy puts the particle on the player

[maiden wadi]

There is a SpawnEmitterAttached function.

[astral epoch]

At location will keep it where it is. Attached will, as the name implies, attach it to the bone.

(is it bone? attaches to something)

[balmy light]

ill try that

[maiden wadi]

Bone or Socket. Left unset will just set it to 0,0,0 of the attached component.

[astral epoch]

Nice to know.

[balmy light]

i have this, but now i cannot see the particle

[astral epoch]

I believe the "location" is relative to the attached object.

[balmy light]

self is the player pawn

[astral epoch]

So if you're doing attach to mesh and then setting its location to the mesh's world location, it'll kinda multiply by itself if that makes sense?

[balmy light]

that does not make sense to me unfortunately

particle attatch to player so it looks like they have been set on fire is my goal

[odd ember]

drop the location and see if mesh alone works?

[balmy light]

ill try that

[astral epoch]

Lets say your character is at x 500.
Particle attaches to that mesh, then you're giving it an extra 500 through that location. So the particle itself is at x 1000.

[balmy light]

i can see ut now

and i think i see what you mean

[astral epoch]

Location is relative to the object.

[balmy light]

however the particle is rotated 90 degreed gotta fix that

[astral epoch]

Just change the rotation value by 90 in whatever direction you need.

[balmy light]

i see what you mean now

location like the thing it is attatched to serves as 0,0,0 for the objects relative location

[astral epoch]

Yes

[balmy light]

it is working now thanks!!

now i just need to get it to go away after a bit but also come back

[astral epoch]

The return value is the spawned particles. You can destroy that directly. Best use a delay or something.

[odd ember]

there's also an auto destroy option

if your particle is one that fizzles out

[astral epoch]

That too, though depending on how your particle system is set up you might want it destroyed sooner?

[fair magnet]

Could someone explain the "SaveGame" Checkbox for me?

[odd ember]

https://tenor.com/view/well-yes-but-actually-no-well-yes-no-yes-yes-no-gif-13736934

[fair magnet]

Yea but what does that mean :o

[astral epoch]

You'll need to look up tutorials for how to save games.

[balmy light]

uh about the particle effect

[astral epoch]

But a serialized value can be stored into binary.

Which is kinda what you need for saving data.

[odd ember]

serialization is the procedure of turning variables into binary data that can be stored on disk. later when you load a game you deserialize the data

[fair magnet]

I know how to use savegames but never had to tick that :o so how come?

[balmy light]

it was becoming persistent when being applied by multiple sources but i think i fixed that with a do once node that resets after the particle is destroyed, but now i think it is somehow causing a bug with anohter AI task of a different enemy

[astral epoch]

(I think. Its been a while since I did this)

[odd ember]

I don't know how relevant it is in BP tbh, I use it in my cpp save system

[astral epoch]

Depending on the type of data. Stuff like bools, ints, floats and strings are easily saved.

Like some things are already serialized.

[odd ember]

primitive types are most likely preserialized

[fair magnet]

However can't hurt to tick if I need to put it in savegames?

[odd ember]

and I don't know if BP allows for actor serialization

[astral epoch]

Suppose not. Don't know if there's any harm in checking it.

[astral epoch]

It... shouldn't? What's the bug?

[balmy light]

so i have an enemy that repeatedly throws grenades at a random interval between 3.5 and 4.5 seconds. It appears that after the particle effect is destroyed, he will throw two grenades and then stop completely. However, without having experienced the particle, he does it as normal.

i will test for this bug's exact cause further and then get back to you

[astral epoch]

I don't understand how a particle effect being spawned and deleted would affect an AI. Does he need to see the target or something?

(I don't know if particle effects can actually block AI visibility)

[balmy light]

he does need to see u yes

[astral epoch]

Okay it might be the particle effect is preventing him from seeing you.

[balmy light]

however it appears that this bug is more elusive and my tests are inconclusive, so the particle effect is unlikely to have been the problem

he working fine even though i have changed nothing about the code we worked on

[astral epoch]

Welcome to programming 😂

[balmy light]

whether he decides to throw grenades or not appears to be almost random

[balmy light]

yeah lol, i been studying this in college for about 10 months.\

[astral epoch]

I've been studying for about 10 years

[balmy light]

dang thats like half my life

[astral epoch]

You never learn more about code, only how much you don' t know 😂

[balmy light]

its like dark souls

its hard but you do it because its easy

the mentality of a souls player

thanks for your help!!

[hushed gazelle]

im doing directional rolling whilst in "combat mode" and im trying to figure out diagonal dodging, what would i put inbetween the nodes to determine which way im moving?

[gentle urchin]

you could make it a singular value 0 to 8 😄

with some binary-like math x)

[odd ember]

in reality aren't there just two options? either it's a forward roll, or it's a lateral roll

[odd ember]

and in either case you can check the direction the player is facing rather than having to deal with x amount of variables

[gentle urchin]

damn, i was to fast

duplicate

• there we go

[hushed gazelle]

i do have a direction the player is facing but this is for a lock-on mode for when im facing my AI

[odd ember]

right even more so you only have two options

[hushed gazelle]

im kind of a noob so i dont really know how i would implement that

[gentle urchin]

this would be the directions

(Fwd * 3) + (Right * 2)

[odd ember]

just check this: is input vector == vector right? or vector forward?

[small halo]

goodluck

[odd ember]

if it's a lock on you can't roll diagonally

[gentle urchin]

true, then you'd only need 4 directions

[odd ember]

2

[hushed gazelle]

yeah ill probably just go for the forward/backward and left/right

[odd ember]

forward and backwards the same. right and left are the same

looks like a #cpp question

[small halo]

trying to attach an aoe effect onto a mesh which has a delay of 3

https://gyazo.com/bd1a9a650e0372c4e5874c2cdfbcdcf3

[gentle urchin]

missed the lock part

[small halo]

but only triggers once

[odd ember]

even without the lock it's only 2 directions

[hushed gazelle]

thanks anyways for the help

[gentle urchin]

Right and left would differ, would they not ?

[odd ember]

left is inverse right

[gentle urchin]

so !right

[odd ember]

well no on the animation itself

or rather I should say mirrored

nothing to do with values

[gentle urchin]

So then its only a matter of checking magnitude , no ?

[odd ember]

for values you just check which axis you are on

[gentle urchin]

which axis is 'biggest'

[odd ember]

you can just check the movement vector

instead of input scale

[gentle urchin]

Hm

sure its view direction directional dodge rolls?

Guess I missed that part too

[odd ember]

compare it with the camera vector (which is our screen) and determine from there

[gentle urchin]

🥱

Lock on -> fixed on target view. Sorta expected input being key to which way to dodge roll

[odd ember]

right but you don't need one for every direction or you'd need a lot of different animations. generally you just have a sideways roll for lateral movement and a forward for back and forward

instead of 8 or 12 or 16 different animations for the same

[gentle urchin]

Yeah for sure

many just use one

and do some insta rotation

or very fast interp

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

at the 3 sec mark

instantly rotated, and dodge roll

anyhow

[tawny root]

Hey I have been trying to make an in depth injury system for my main character (it's a robot) and I am trying to implement what I call a rusting effect. Where depending on just how much accumulated time has been spent in the rain the characters body begins to rust.
But as I develop just what are things I should consider while developing a more advanced injury system?

[vagrant lintel]

Programmatically or gameplay-wise? You could have some sort of "game states" such as "is raining" or maybe volumes? Hmm...

[tawny root]

What I'm saying is what should I plan for when trying to design a complete injury system?

[vagrant lintel]

Can specific parts get injured or is it just one main health bar? Do different types of injuries do different things? Are there other stats involved like they have in RPGs?

well specific parts do get damaged but most of the things that can kill you exist environmentally in the 3d environment.

can I swap out entire limb's should their health reach zero?

things like this matter due to the options you have in the game I think

Like regenerating limbs and vaccines that are specific assets for treating different conditions

To be honest I'm really unsure how an injury system is laid out without it getting too complex

Swapping out meshes?... that could be one way, or material editing.

Depends on how detailed you are making the graphics.

hey everyone - so i have a few BPs in a level that all have the same trigger (action input map) that triggers a timeline and then a toggle visibility but in each one (bp) the timeline is different. When i go to play only one of the BPs actually work, is there a way to fix this or do i need to set it up differently? cheers

for example - i have two variations of this bp - and only one works when both are in the same level at run time

i'd really love some input

I believe there's an option to not consume the input

[native ice]

i assume consume would mean that particular bp would take priority over any other ones?

[desert juniper]

There we go. untick that.

YOU LEGEND!

thank you so much
