[smoky marsh]

Ah, just have the player send a call to the level when it's been loaded in to let the level know it's ready to be shipped off to the right place

This way you garuantee it's loaded, since it's sending the message instead of hoping the timing is correct on the levels side

[mossy mist]

how do iget rid of

bp_rifle_c

and rename to

rifle

im doing a print to screen with a get name

[icy dragon]

Should not be that detrimental for print string, because it's development only and won't appear on shipping builds, but to compensate for possible OCD...
(leave the To input blank)

[mossy mist]

tysm

[gusty cypress]

Thats where I started a year ago here I am still looking for a good method

I'll try this and lyk, also my code would work like 70% of the time ranging from 1-2 seconds off which I found odd since theres 99 miliseconds it could be off but it was only 1 or 2 seconds off always

[umbral ginkgo]

This is strange, but how would I go about checking to see if a number is an interval of 2 (for example)?

[tired cypress]

Are you wanting to test if a number is divisible by 2?

[umbral ginkgo]

Yeah thats a better way of putting it

[tired cypress]

There's a node for modulus

It will tell you what the remainder of a division statement is, so check for that to be zero

[umbral ginkgo]

ok so, this is going to sound very strange, how do I put a number to (lets say the power of 5) then for each time its multiplied, make a variable for that number and then check to see if a different number number is one of those variables

[tired cypress]

You're right, that does sound very strange lol.

Could you reword what you are trying to do?

If I am understanding correctly, it sounds like you want an array and run a foreach loop that will perform an operation and store that result into one of the array elements

Then later, if you need to, you could run another foreach loop to check those array element values against a given number

[umbral ginkgo]

Dont arrays just get a random number?

or do they have more use cases?

Ok lemme explain this better

Lets say in a hypothetical situation, every time the player presses e they are given one cookie. When they have 50 cookies they make 2 cookies per e clicked. When they have 100 cookies they make 4 cookies per e clicked, and so on

Thats kind of the same general concept of what im trying to achieve

Except with a weird example

[tight schooner]

Divide by 25 and then truncate. If the remainder matters there's a node called Division and Remainder or something like that. Modulo (%) gives you the remainder on its own

So if you have 80, divide by 25 & truncate will give 3. Modulo (by 25) will give you 5.

An integer division does the truncation automatically iirc...

[umbral ginkgo]

What does truncate do?

[tight schooner]

Turns a floating point value into an integer by keeping only the whole number

3.75 truncated is 3

(rounded is 4, e.g.)

[umbral ginkgo]

Ok, so the numbers being divided are all ints

[tight schooner]

I think Divide (Integer) throws out the remainder automatically

So no need for truncate iirc...

[umbral ginkgo]

yeah, thats what I was thinking

So whats the difference between divide and modulo

They seem to be similar

[tight schooner]

Modulo gives you the remainder in integer form

[umbral ginkgo]

ok

[tight schooner]

So if you have 80, divide by 25 & truncate will give 3. Modulo (by 25) will give you 5.

[umbral ginkgo]

ok

[tight schooner]

Like khade said earlier, you can modulo by 2 to check if a number is even or odd, as another practical example

[umbral ginkgo]

Ok, but what would I do if I purely want to check if a number can be divided by lets say 100

[tight schooner]

Then use Divide (Integer). 355 divided by 100 (int) will give you 3

If you just want to know if it's at or over 100, then the >= node exists

[umbral ginkgo]

Yeah

my problem is you can have an infinite amount of numbers in what im working on

and doing >= is really innefficewnt

[tight schooner]

If you want to know if it's exactly at 100, 200, 300, 400 etc then mod by 100. If the result is 0, then it's at one of those intervals

Cuz mod gives you the remainder of a division

[umbral ginkgo]

Ok, that seems to be more along the lines of what im looking for

thanks

[umbral ginkgo]

is this kind of what your thinking?

[brazen merlin]

I see upgrade... so is this experience or something?

[tight schooner]

Probably, as long as your system never skips over the 100th value when it's incrementing. I find it easier to check if dividing by (e.g.) 100 the current total vs the new total produces a new whole number

[umbral ginkgo]

k

[tight schooner]

Like if 399 goes to 401

Divide (int) by 100 will give you 3 and 4

[umbral ginkgo]

what do you suggest instead

[tight schooner]

Then check if [3] ≠ [4]

And if that's the case, you leveled up

Otherwise you have to make some level up system that increments numbers one at a time if you're doing the modulo-by-100 approach

Modulo is good for updating a progress bar though

(g2g)

[umbral ginkgo]

Kind of but not really

think of it as selling ice cream

except after you have a couple hundred customers people start paying you more for the ice cream

and after a couple hundred more they pay double whjat they did before

[brazen merlin]

So based on certain milestones, the cost of ice cream increases by some degree? And they are always at increments of 100?

[mossy mist]

hi im calling

show mouse cursor

but mouse cursor isnt showing up?

[thorn fiber]

From Player Controller?

[mossy mist]

yes

[thorn fiber]

Did you put a break point there? Are you sure it is getting called?

Are you adding the Widget to viewport btw?

[mossy mist]

yea

breakpoint getting called

its just not showing up

[thorn fiber]

Before that call can you try doing Set Input Mode UI Only

[mossy mist]

sure

[thorn fiber]

and feed it the new widget you make

[mossy mist]

ok so it made it so i cant move my character around but i still cant see a mouse cursor

[thorn fiber]

Hmm I'm not sure atm

[mossy mist]

yea

[thorn fiber]

if I think of something else I'll let you know

[mossy mist]

aight thanks

[fiery swallow]

See if you can get the mouse cursor to show by using an input action

[mossy mist]

even running it through a widget through tick seems to not work

oops

discor dlag

[fiery swallow]

Just put it on a random key, and when you select the key call set show mouse cursor

[mossy mist]

aight ill try

[fiery swallow]

Just need to find the issue

just go to your character blueprints and do this

https://gyazo.com/5da09a50db5a58ff8421a68ba2aa9461

@mossy mist it won't immediately fix your problem but it should let us know immediately if set show mouse cursor is working at all

[mossy mist]

ty

so i

was able to get it running through character by pressing e

actually through even tick

so it only works

if run through character

for some reason

[fiery swallow]

it should work in the player controller as well

however you're using a replicated event when you call "set show mouse cursor" and that might be causing the problem

[mossy mist]

wait

that might be

lemme test

hm

still doesnt work with unreplicated event

[fiery swallow]

try it in standalone

[mossy mist]

aight

[fiery swallow]

do you have multiple clients open?

If you are using multiple clients then you need to do it this way

https://gyazo.com/e25cd02bdb244ba684a5623856bec085

do not use get player controller

[barren relic]

is it possible to attach a hitbox to a bone/socket?

[mossy mist]

no only listen server, and unfortunately doesn't work in standalone either

[brazen merlin]

sounds possible

[fiery swallow]

Did you try the new method I just told you?

[mossy mist]

yea

[fiery swallow]

That didn't work for you?

[mossy mist]

couldnt move but no mouse cursor

[fiery swallow]

Can you show me the event that calls show lobby menu

[barren relic]

thanks conrad

[brazen merlin]

i believe in you

[mossy mist]

got a post login

then cast into

[barren relic]

appreciated!

[mossy mist]

then

[fiery swallow]

Is that game mode?

[mossy mist]

yes

[fiery swallow]

Can I suggest call that setup lobby menu somewhere else like on possess

[mossy mist]

aight ill try that

hm

still doesnt show

[fiery swallow]

No possess on player controller

[mossy mist]

ohh

[fiery swallow]

When the Controller posses a pawn it should setup the lobby menu itself, it doesn't need to be replicated by the server

[mossy mist]

hm

lemme try without replication

still nothing

[fiery swallow]

Im at the movie theaters gg

Watching superman sorry bro

[mossy mist]

rip

aight thanks anyways

[hollow scaffold]

Very noob question incoming: How can I reveal the type of a blueprint node input/output parameter?

For instance, how can I see what kind of thing needs to be input into UVs in this pic?

Looking and clicking around the UI, I don't really see any type info for it

Even the docs don't seem to give type info? https://docs.unrealengine.com/4.27/en-US/RenderingAndGraphics/Materials/ExpressionReference/Parameters/#texturesampleparameter2d

[icy dragon]

That accepts float2, and Material graph isn't the same as regular BP.
https://youtube.com/playlist?list=PLZlv_N0_O1gbQjgY0nDwZNYe_N8IcYWS-

[hollow scaffold]

Thanks, I did find what it accepts by searching around the internet... but is there no way to reveal type information directly within the blueprint editor?

[tight schooner]

Generally you'll want to ask material node graph questions in #graphics cuz it ain't BP. To answer your direct question, idk. The material graph nodes aren't strongly typed. Sometimes the inputs say what they expect, and sometimes they don't; you just have to compile the material and observe the error.

UV coordinates are definitely float2. A lot of other things are implied, like RGB is float3 and RGBA is float4, etc.

[hollow scaffold]

Gotcha, thanks for that!

[tight schooner]

and if you multiply a constant (float1) by a float3, the output is a float3, etc.

you'll figure it out as you use it more

[hollow scaffold]

Gotcha. Sad to hear that it's not explicit about types because that means I'm going to make a bunch of unnecessary mistakes, but if that's the only way then that's the only way

Thanks!

[tight schooner]

I wish there was more consistency across the different node graph systems of UE4

wait until you see Niagara

[dawn gazelle]

OnPossess usually only occurs on the server, so that still wouldn't work for you. Could it not work on BeginPlay of the client's copy of the player controller seeing as it is a lobby UI?

[vagrant flicker]

Hey guys. Trying to do pretty basic stuff but I am failing somewhere in the middle

https://blueprintue.com/blueprint/z5eewsk2/

basically, I am trying to move a platform based on its state (true or false)

I tried to plug select in on/off conditions but with no success either

[gentle urchin]

since you reverse it, assuming its gonna move at the same speed both w ays, you dont need two lerp curves

just one

0 to 1 will go 1 to 0 in reverse

[vagrant flicker]

Its not starting at all 🙂

[gentle urchin]

Still dont need that node at all

[vagrant flicker]

the select?

[gentle urchin]

ye

[vagrant flicker]

So just plug movement node to alpha of the lerp vector

Sweet

[gentle urchin]

Then make sure your target location != 0,0,0

lastly make sure your curve in the timeline goes from 0 to 1 over given duration

[vagrant flicker]

All met

[gentle urchin]

curve goes higher than 1 it seems

more like 1.6 or smth ?

this wont break it, but im not sure if the lerp is clamped or if extrapolates

[vagrant flicker]

Ye, I've messed up because my length is 1.5

Fixed it to 1

[gentle urchin]

Now the last thing is to trigger it

for testing the timeline itself (the logic in the platform) you can simply use beginplay to start the timeline

it should work as expected, in one direction

[vagrant flicker]

Yes, it triggers fine. My problem is somewhere in this branch with the on/off
If I remove it and plug the toggle on off state directly in the play node, when I trigger using the laser it's working fine

But I need when the laser is not on the right spot, to reverse and lift up again the platform

[gentle urchin]

so... show that logic?

[vagrant flicker]

This is the receiver

Sorry, bad image quality

[gentle urchin]

Its fine

Windows + Shift + S = Snippet : )

very helpfull so you only post what you want to 😛

so is this part triggered? the interface event?

[vagrant flicker]

Yes

[gentle urchin]

if all events fires, then it works

congrats

[vagrant flicker]

oh fuck me

[gentle urchin]

what im seeing is that the actor doesnt use the interface event

so

thats one hickup

[vagrant flicker]

I tried to debug the branch and after true node print something, after false print another, and it's seems to not work as expected 😄

[fiery swallow]

You have no idea how many times my lead programmer has had to remind me that on possess and on unpossess is server only oops.

[vagrant flicker]

For some reason on the true side it prints me "false" and when I remove the laser from the trigger it prints nothing

It's not handling the on/off switch properly I guess

[gentle urchin]

you're calling the wrong event

so

atleast the one im seeing on the screenshots you sent

[vagrant flicker]

how so

[gentle urchin]

you're calling an interface

yet not using the interface

(and you shouldnt need to i guesS)

interface message

Native event

interface event is marked like this

[vagrant flicker]

hm

Oh, I found the little devil 🙂

This was the issue. For some reason plugging this directly and changing the material from the receiver BP it was screwing my on/off switch states

And it goes "on" forever

Have to find a smarter way 😄

[burnt citrus]

Hey I have a question
How to change visibility of particles between cameras?
I want to make shooter game with switchable cameras between first person and third person
Then I have to change visibility like "only owner can see" of particles, but I have no idea

[icy dragon]

I think you set that property on the Particle Emitter component (or Niagara System component)

Though that's mostly used for multiplayer views, probably not switchable local camera

[burnt citrus]

I know there is "set visibility" node for particle system
but I want to know is how to change visibility of particles between local cameras
or do you know how to sync the particle effects of guns between TP and FP?
FP and TP have different arm positions so I have to change location of particles, or I have to spawn particles for each positions and change visibility of particles

[spice smelt]

ue docs being as useful as usual... Can anyone explain what's the difference?

[icy dragon]

You could get away with moving the particle around, minus the replication part (if your game is multiplayer)

From what I learned in GTA V, the player switches the animation set and stuff from third person to first person, but this behaviour doesn't get replicated from other player's point of view. This is one of the reason why you can't change the camera angle in Rockstar Editor (the game's replay editor) if you record yourself in first person.

[burnt citrus]

hmm, sounds interesting, thank you!
is there source video or something what explains about that? I wanna watch the theory

[icy dragon]

Sadly I removed my installation of GTA V to make room for custom UE4, so I can't give you the exact screenshot of that.

[burnt citrus]

oh it's ok, thank you

[vagrant flicker]

Hey, Any thoughts on why my casts are failing?

besides the "I suck" part

[icy dragon]

Isn't Get Owner returns player controller class?

[vagrant flicker]

Oh.. How to get my actual class then 🙂 I dunno

I thought It would get the actor which the cast points to

[spark steppe]

why did i read "my cats are falling"?

[icy dragon]

If this is done in the LaserBeam class (should use naming conventions next time), no need for casting to get self.

[vagrant flicker]

This is done in my LaserReceiver BP, not in the beam itself. That's why I am trying to get the beam and change its material :/

[spark steppe]

so the beam is on another actor?

[vagrant flicker]

yep

[spark steppe]

and did you get that actor reference or stored it somewhere? because you'll need it to get the actual beam

[icy dragon]

You might looking for one of these

[spark steppe]

those don't work if he has 2 separate actors

[icy dragon]

Implying that one actor is attached/parented to another

[vagrant flicker]

Nope.. The Beam class actually isn't placed in the scene or declared anywhere. I was able to get it in my third BP which is the emitter by using Spawn Actor From Class

But here it would not work like that

[cosmic loom]

Please ping me when this channel is free. I don't want to interrupt anyone. Thanks.

[vagrant flicker]

Which is the most easiest way of doing that?

[icy dragon]

Just ask right away.

[icy dragon]

The most naive way would be Get (All) Actors of Class, but this can cause a hitch if you have a lot of lazors

Depends on how you actually setup the lazor systems

Gotta redirect this to #animation

[cosmic loom]

ok, sorry

[spark steppe]

for your use case i would also consider making the whole laser thing one actor

[vagrant flicker]

I'll try that. Thank you guys

[gentle urchin]

Snake

[icy dragon]

Some idea from @torn kettle

Maybe Unreal Slackers should have some kind of relaxed game jam where you make game based on @torn kettle's !gameidea suggestion 🤔

[faint pasture]

You need to read up on what exactly casting is. What are you trying to do here, you are trying to establish communication between what and what?

[vagrant flicker]

Between my laser receiver part and the beam itself. the system consist of 3 parts.

Emitter, Receiver and Beam
I am trying to change the beam material to green when I hit the target

Not the smartest way to build it I admit 🙂

[spark steppe]

but why does the receiver have to do that?

could also be the beam which linetraces, and checks if the hit result is a receiver

[vagrant flicker]

That may even be better.. Dunno, I've started that way because I've checked in the nodes before if receiver is hitted and if so - I've change its material and I just continued the nodes to check for the beam itself

[faint pasture]

@vagrant flicker the emitter should do a line trace, see if it hits a receiver, then set the color on the beam. There's no reason for the beam to be a separate actor. It should be a component of the emitter

[vagrant flicker]

Thank you. I'll try to re-do my work

[iron bone]

Anyone have links or suggestions for making a ghost / time trial type of situation? I want to have a ghost version of my main character chasing my player and re-creating all of my maneuvers

Would I be able to have that playing while my game is playing though? Like have the replay happening just seconds behind me and have it be live reacting

Yeah I'm seeing that some more advanced uses of this require C++ knowledge

[mild jacinth]

does anyone know how can i set persistent level player spawn position? and how to ensure that the player does not fall through the ground as soon as the sublevel has been loaded/streamed?

[icy dragon]

Yeah, figured.
As Lorash said, recreate a game from the late 70s to early 80s.

Those games are old and simple enough, and in most cases, well documented.

3D Snake is going to be more difficult though, good luck.

Making the snek bendy-bendy.

[vagrant flicker]

It really depends on what your level is and what are your game preferences. If you like 2D games, we can give you some ideas for 2D games, if you like 3D games etc... And the genre ofcourse. My preferable way is to do platformers since I am learning a lot of them. But in there for example, it's missing a lot of the combat systems nowadays. So really depends on your taste

[icy dragon]

Space Invaders, Pacman, Breakout
Those games are simple enough and the workings are well documented.

Pacman is the more advanced bit among them, in particular the pathfinding

[vagrant flicker]

You can try some basic platformers then. Really shallow mechanics -> Crash Bandicoot for example

[icy dragon]

Damn, pong is almost 50 years old now 😦

[mild jacinth]

.

[icy dragon]

World Composition?

[mild jacinth]

thanks will take look

[icy dragon]

No, I mean, are you using World Composition with the issue?

[iron bone]

Regarding the ghost/ time trial thing, this is what I'm trying to set up but in 3D- Having a ghost character mimic the players every action and move until they catch up. Anyone have suggestions or tips on if this could be done in blueprints?

[mild jacinth]

no, I just created persistent level, then added sublevel to it, persistent level blueprint has a very basic loading screen and then the game starts. persistent level has the gamemode which tells what type of pawn to spawn

If I use world composition right now then it doesn't fall through the ground

[icy dragon]

But as food for thoughts, yeah, record the input

It's how Doom's replay system did it

[iron bone]

This seems like something I might try considering my limited knowledge this seems the least stress and hair pulling inducing

[fiery glen]

Variable tickrate might make input playback dicey

[icy dragon]

It will fall through the ground, on standalone process.

[iron bone]

That would probably require some C++ though?

[icy dragon]

Yeah, Demorec did require going through C++. at least no BP functions exposed by default on it

[iron bone]

okay thats definitely more hair pulling then lol

[icy dragon]

I think even with input recording mode should be done with C++, because with BP tick, it may affect performance. However, for prototyping purposes, feel free to do it in BP.

[iron bone]

I have never touched C++ so I'm just trying to avoid it for this game which is my first project and introduction to unreal

it's a bit overwhelming for me atm but i do understand i will have to learn it eventually to do some more advanced things in unreal

[iron bone]

yeah I decided for the time being to just use a simple move ai to type of situation

[vagrant flicker]

@trim matrix Are you trying to import mixamo animations? You have to do additional config

[icy dragon]

Are you using Blender?

Oh, Mixamo. Chances are only the Mixamo bones got keyed.

[iron bone]

thanks for the feedback btw, it's super helpful having more experienced users to bounce ideas off of!

[vagrant flicker]

Look for "Mixamo retarget for ue" in youtube. Sorry, I am on the phone now

You will find a lot of tutorials

[faint pasture]

Sure, just pay DC comics $1 million to license their character first

Yes it sounds like a great idea. Go ahead and pre-order your Lamborghini

[icy dragon]

Hope you win competition against Dreamworld

Dreamworld singlehandedly defame our beloved Manny

[pastel rivet]

How can you get the overlapping static meshes of an actor, if they are spawned at the same time? It doesnt seem like the "get overlapping actors" or components is working. Setting the generate overlap events + overlap events during level stream works AS LONG youre doing it from editor. Setting these to true by blueprint isnt working

None of these will trigger the print, i guess the overlap event check box doesnt happend before AFTER both objects are created causes the issue

is there anyway to refresh or make the collision recheck for actors overlapping?

[unique wasp]

When object pooling, what's the proper way to enabled/disable an actor? Will calling this pair disable everything, or do I need to do more, for example in case of animations or Tick events?

[spark steppe]

you may also want to disable ticking for the actor

or just destroy the actor and respawn it when necessary

[unique wasp]

is there no "removeFromWorld" or something like that?

[spark steppe]

no

[unique wasp]

I need to spawn and remove dozens of actors simultaneously, so I figured object pooling would be the right thing to do?

[spark steppe]

remove from world is like destroying it

if you don't need the actor destroying is the way to go

they'll be marked as garbage and removed on the next garbage collection run (and until then they basically have no cost, as they don't get ticked or something)

[unique wasp]

in this case the same actors are repeatedly made and removed, when the user enters or leaves a certain UI mode

[tight schooner]

Visibility, collision and Set Actor Tick Enabled are the only considerations for a custom pooling system that I can think of

[pastel rivet]

Would toggling the visibility retrigger overlap events?

[unique wasp]

will for example particles and bone animations automatically stop then?

[tight schooner]

Oh, good point. I never tried hiding a particle system so idk if they still simulate while hidden.

Couldn't tell you about animations either

[unique wasp]

(not that I have that in this case, but I'm trying to understand in general how object pooling works in Unreal)

[pastel rivet]

Yes, figured it you can retrigger it

[icy dragon]

Depends on what you want to achieve

That includes project specifications, jobs, etc.

If you want to use UE4, start with BPs.

And on the topic of getting started
https://www.unrealengine.com/en-US/onlinelearning-courses

That depends on your mesh.

No need to flex your JoJo stand 🙃

Again, depends on your mesh. You create the material slots in your DCC tools.

[dawn gazelle]

Materials are assigned on a mesh. It's not something you can just "add" to an existing mesh without defining what part of the mesh the material needs to apply to.

You can open your mesh in 3D editing software, assign a material slot to the appropriate faces of the mesh, then reimport the mesh into Unreal.

[icy dragon]

You do that with particle effect

Achievement: Opened a new can of worms

Don't watch that indian tutorial lmao (I'm guessing CGHOW here)

Oh, that one, still terrible tutorials tho 🙂

Niagara can do that, just spawn particles on skeletal mesh and it's flash time
Try getting the hang of it here, and start improvising from it
https://www.youtube.com/watch?v=syVSRDQxrZU&t=52s

[tight schooner]

Only for mesh particle systems

[lyric relic]

QQ, just to make sure, If I connect an object to the FPS player actor that comes with the FPS template, using physics constraint, it's not gonna work coz the FPS player needs to move with physics, is that correct?

[icy dragon]

Sexual innuendo
Sorry if you're younger than 17

[dark crow]

🔥

[hallow wraith]

every time I compile my main char BP, UE jumps to 100% memory consumption and the whole thing freezes. if I kill it and restart, the compilation seems to have worked.

... is there anything in particular I can do to debug this?

[dark crow]

Burn it

Does it only happen in the char BP?

[hallow wraith]

yes... well i have compiled a couple other BPs successfully.. haven't tried a bunch of them

[dark crow]

Can't really give you a proper answer since I know nothing about the class

Look for circular dependencies

[hallow wraith]

aight

thanks

can you "comment out" or disable sections of code in a blueprint?

i guess i can just unhook it

aha unhooking it works... found the offending section

[tight schooner]

There is a way to right click and disable/bypass nodes... IIRC it requires some option to be set in the project or editor settings

[hallow wraith]

anyone see anything that would break stuff in this section? lol

respawn upon destroy char

[brazen merlin]

so you spawn the same class when it gets destroyed?

[hallow wraith]

that was my intention.. is that a problem?

when char dies... make new copy of char

i see the circular dependency now tho that you mention it

[icy dragon]

When character dies, change the state to dead

[dark crow]

Yes, there's a very useful feature

Editor Preferences -> Enable: Allow Explicit Impure Node Disabling

Then right click and you'll have the options

[brazen merlin]

the only time i see this even firing (or should fire) is when player meets killz

[hallow wraith]

thanks @dark crow

[brazen merlin]

but you should just teleport the player

[hallow wraith]

oh lol

yes i should

aight

thanks

[dark crow]

So you don't have to detach stuff everytime

[hallow wraith]

love it

thanks

[dark crow]

You can make a Print String show in a shipped build like that too if you want

[storm lagoon]

Hi everyone!
I have this actor blueprint class called "BP_Log", with an actor component blueprint class called BP_CraftableItem (where this stores it's object name so i can use later on a crafting widget).
The thing is, when the user press "C" , it opens an widget called W_BuildMenu. This widget, on Construct, executes a for each loop within a actor class array and tries taking it's "Item Name" in the BP_CraftableItem. I've tried a lot but can't find the exactly castings to be done. Can anyone help me?

[graceful holly]

hello! whe i'm using an if statement do i always need to link it to a trigger event? What if i need the if statement itself to be the trigger?

[sinful moth]

I'm kinda new with blueprint so I don't understand everything. How can I simply create a boolean variable and set its value after clicking a button? Something like this in written code

foo = true

if button.clicked = true
  foo = false
end

Nvm. I actually need to toggle the boolean value when I'm pressing M

Or can I just use the FlipFlop node to toggle between 2 states?

[dawn gazelle]

Whatever triggers the event (say an increase in score in your scenario) should be what triggers the check.

[spark steppe]

dont use a flipflop

just set the boolean with the currentvalue running through a "not" node

so foo = !foo

[sinful moth]

how can I create foo?

[uncut lark]

So I have about 4 weapons that draw ammo out of the same ammo pool. Is it going to be okay if everything is just housed inside the player blueprint

[spark steppe]

there's a variable section in the blueprint where you can define variables

but this sounds like you should watch/read some basic starter tutorials

[sinful moth]

Yeah I think that's a good idea, thanks anyway!

[faint pasture]

I would have ammo live in an Inventory Component especially if other inventory things are gonna be a thing, but sure.

[faint pasture]

If is just a conditional. You gotta decide WHEN to do your score check. I'd do it whenever score is modified.

[ruby cobalt]

is it normal that print string doesn't show up on screen in unreal 5?

also where is the "log" exactly?

[olive cloud]

Open the output log tab

[ruby cobalt]

ok got it.. and I just tried to print something else and it works

so the print is not my issue.. hmm

I'm trying to receive OSC

it might be because I'm trying to use UE5.. I still don't understand why game engines cannot be upgraded as easily as other softwares

[brazen merlin]

other softwares? what like maya? photoshop?

[spark steppe]

maybe, just maybe don't expect from something in development that it works out of the box

also UE4 => UE5 compatibility is already pretty good considering that it's a major engine upgrade

[ruby cobalt]

got it.. I'm following a tutorial for 4.25.. something changed in 4.26.. at least now it works but yeah I feel like with UE.. this happens A LOT

you can't just open a project from 4.25 and use it in 4.26.. chances are something changed and you're screwed.. it's hard for noobs

[brazen merlin]

try watching maya tutorial videos on how to model or uv.... good luck translating maya 2011 to maya 2022

[ruby cobalt]

you almost never get this with other softwares

oh maya suffer from this plague as well?

[spark steppe]

because they barely improve existing things

[modern musk]

I get this:

[brazen merlin]

more dev software than you know

[ruby cobalt]

what about blender? you can still open old projects, no problem

touchDesigner.. I could open a patch from 3 years ago and maybe have to change 1-2 things max

I'm annoyed by it but I will over come it.. it's just harder to get into Unreal because of this.. you can't use older plugins or tutorials

[brazen merlin]

yeah, you can usually open old projects - if you're saying Unreal cant open old projects well, then go try in Unity - Blender is a 3d software, Maya can open old projects as well, no problem

[ruby cobalt]

what makes it trickier as well is that I'm not trying to make a forest level lol.. there isn't much documentation covering what I'm trying to do

[brazen merlin]

this all just sounds like a personal learning curve, nothing to do with software

[ruby cobalt]

yeah it's definitely subjective.. but most tools don't suffer from this

at least not as much

I'm dedicating most of 2022 to game engines and I will get outside help.. I'll overcome this.. I'm just wondering why it happens

[muted edge]

Is there a way to add a weapon to the players screen where you can add attachments? im trying to make a weapon system

[trim matrix]

At what point in the level load is gamemode reset? Im creating a player then spawning that player in the gamemode and storing the spawned actor as a reference. I can print the reference in the gamemode and it prints but in my camera in my level, which is referencing the variable in the gamemode, its empty. I'm doing the same thing for player 1 and it's returning player 1, but not player 2.

I should add the player is actually spawning and is controllable

[graceful holly]

how can I write a logic that does this " if value X is higher than 10000, 20000,30000 (and so on) do something". I tried creating a array but I can't check one integer and one array of integers

[trim matrix]

Are you checking them sequentially?

[brazen merlin]

you need a for each loop to work with arrays, to the process each index

[trim matrix]

For each (array of integers) if highscore > array value then do this

[graceful holly]

like this?

[trim matrix]

That will probably give 1 for every array value if its true. Is that what you want?

You probably want to break out of the loop once it hits a true statement. Maybe not though.

[storm lagoon]

Can anyone help?

[faint pasture]

Divide by 10,000, truncate, switch on it

[muted edge]

Can anybody help me?

[graceful holly]

the thing is that if highscore<20000 then nothing should happen no?. right now hisgscore is 10000

[faint pasture]

Yes there's a million ways and it'd be way too much to feed you step by step. Find a tutorial.

[trim matrix]

Yeah but if the score is 50,000 every iteration through the loop will give 1 life. 20,000 30,000 40,000 50,000 giving a total of 3 extra lives

the*

And it will do that every time you check the score

[modern musk]

Rephrasing a previous question: Are exposed vector variables always local in relation to their owning actor?

When I expose a vector variable and toggle the "show as widget" feature (in order to debug) and then set the vector variable to the owning actor's "WorldLocation" the two do not align.

[muted edge]

looked for one, they only showcase it not really go into how to actually create it

[graceful holly]

ohhhh, ok

[faint pasture]

Start with adding a weapon then experiment with attaching things to it. You sound new, don't just dive gung ho into trying to implement some big system, start with the absolute basics.

[modern musk]

I'd recommend looking at inventory system tutorials. Most of them will be for character's, but the underlying process will be the same (if I'm understanding you correctly).

[muted edge]

I'm not that new, i know how to attach things to the mesh etc, im trying to display it on the screen but thanks anyways ill have a look see if i can find something

[muted edge]

Kinda, have you ever played Escape from tarkov?

[faint pasture]

Define "display on screen". Do you mean UI?

[muted edge]

Its something like that

where you can customize the weapon, like stocks, scopes etc

i have the UI, on the screen

with the buttons

[faint pasture]

You're going to need a whole framework for the concept of a gun having accessories.

[modern musk]

@muted edge I haven't but I know of it. I just checked out the weapon mod system in a video. Definitely look for an inventory tutorial, you should be able to create a similar effect using UE4's UMG.

[muted edge]

ill check it out thank you

[faint pasture]

@muted edge One thing to keep in mind is to always start with the data. What does the definition of a gun look like? You'll probably want something like a struct with a gun class and array of attached part classes or something of the like. Start with the data, and the code for manipulating it will be obvious.

[modern musk]

Just as an added search term, looking into character equip sheets would probably be helpful as well.

For instance, the project I'm working on lets you open a character sheet to equip items, the character sheet has a 3d animated model of your character and that model updates when items are added and removed. Modding the gun in Tarkov should be able to use nearly identical logic.

[zealous fog]

Is there an easy way to move certain functionality from a child to a parent class? I added some code to an intractable BP class but I wanted to move that code to the parent instead of it being limited to that class

Or will I have to copy every function

[faint pasture]

Do yourself a favor and put it in a component

[zealous fog]

I'll look into that

Why into a component?

[brazen merlin]

though i like class based inheritance for certain cases, this Interactable BP sounds like it would benefit from being a component so it can be a component of any actor you'd like to be a part of @zealous fog

[muted edge]

Appreciate it

[zealous fog]

What's the benefit of components vs inheritance?

[trim matrix]

Components can be attached to anything and reused.

[brazen merlin]

the problem you have right now is one with inheritance

[brazen merlin]

making the code work in a self-contained component makes it like a piece of code you can tack on to anything

[zealous fog]

Makes sense when you put it like that haha

Thanks for the help

[umbral ginkgo]

Is there a way to see if something is equal to any whole number?

[trim matrix]

If you made the component an intractable you could essentially make anything intractable instead of requiring it be a child of the base class

interactible *

[zealous fog]

My first idea would be to round the number and see if the rounded number is the same as the original number

[umbral ginkgo]

Thats one way of doing it

[zealous fog]

Might be an easier way out there

[blissful grail]

I prefer interactables to be interfaces instead of components. Much more lightweight.

[ruby cobalt]

I want to move my first person character using OSC.. at the moment I can set the actor location of an actor as long as I specify it.. however, my first person character is created on Play.. how does that work? Could I just set it to use an existing actor as my player?

[brazen merlin]

i would also say interfaces are the more flexible object than components if possible

[zealous fog]

Yeah im using an interface to interact with the object

[brazen merlin]

blueprint interface?

[zealous fog]

Yes

[brazen merlin]

not umg

[zealous fog]

No

[brazen merlin]

nice

[faint pasture]

You can do something like interaction with an interface or a component. We use a scene component because then you have the point of the interaction happens at, and also can store some State about interaction on it

[brazen merlin]

ah right, use both

[uncut lark]

Why do you say that? I just need the player to have one ammo count and a quick heal object. Is it going to not be as efficient if I just tie the ammo to the character blueprint and say "If weapon 1 is selected, then fire it this way and take ammo out of the ammo pool"

Like it seems simple enough

[trim matrix]

any tutorial ?

[trim matrix]

Rofl

[faint pasture]

If it's one and done then sure, do it like that. If you plan on having like more stuff in your game, then start thinking about a decent inventory system. I don't know how big of a game you have planned.

[uncut lark]

Yeah its just an FPS. just 4 set weapons, healing items and one type of grenade. Its not going to be ground breaking

[blissful grail]

Also keep in mind, if you respawn (not reload) the character, it won't remember the previous pawn's state.

[young sandal]

Maybe somebody can help me with this:

I have a game mode which 'creates' a second player, and on my handle new player event in the gamemode, I spawn in the second player, then store the actor in a ref. The character spawns in.

On my camera, I reference the game mode and the player 2 reference I made, but it's empty.

I do the exact same thing for player 1, and player1 has a valid reference. Am I missing something?

[dawn gazelle]

I'll take a shot at answering this, though if I'm wrong, I'm sure others may jump in.

When you are dealing with regular applications, they change the format of the file and give it an entirely new extension or some sort of version code within the file. So when dealing with things like photoshop psd files, or blender files, when they're going through versions, they can keep code meant to open different versions of files relatively easily as they can just read what they need to from the file and recreate it in the new structure. It's not a huge hassle as it's a known format. It's probably fairly easy to just read the file and display it as it's a known format, always.

When dealing with an application meant to help you design an application, such as Unreal Engine, you're dealing with a much larger beast, especially since it has a visual scripting layer on top of everything.
For one thing, you're not dealing with opening single files, ever. You'll literally end up dealing with thousands of different files in an Unreal Engine project. The majority of these files won't have problems loading up in a new engine version as nothing would have changed with how those files are handled, and the underlying code for most things doesn't change much between versions, but of course, there are exceptions to this as the engine gets changed over time.

The reason why you have trouble is you're dealing with both a visual scripting language, and a text-based language that requires you to feed in the right instructions in the right way. An analogy would be instead of you drawing something in photoshop with the provided tools, you're telling photoshop to draw a specific set of pixels a specific color, and it's expecting a certain format for how you're telling it to do it, and if it's not right, it can't do it. There's no "previous version" of a file format in this sense either, as you would need previous versions of every single function created which would cause extreme bloat of the already 60GB+ engine, and it would make it near impossible to expand and maintain.

Unreal Engine then helps you convert your code to machine code so your computer can work the magic and display what you want it to display. If the Engine expects something a certain way, you need to make sure your thing is that certain way. There's no "fix it for me" in this sense - it can't just open an old version of your code and make it work with the new code in the updated version of the engine.

[trim matrix]

Is Trigger Reference set already?

[dawn gazelle]

Looks like you're missing setting Player2 Ref. Nvermind

[trim matrix]

@dawn gazelle third screenshot at the end (The Spawn Player 2 function)

I can reference P2 reference inside the gamemode, but for some reason the camera can't reference it. But it can reference player 1.

[dawn gazelle]

So the problem could be your begin play is firing in the last image before the ref is being set in the game mode.

[trim matrix]

Yeah that's why I asked at what point gamemode is created. I'd think it would be before anything else was, but who knows.

The beginplay is attached to the camera object placed in the scene, so I wouldn't think that would be created and available before the gamemode was.

[young sandal]

Yes, I created an object and called the trigger dispatcher.

[dawn gazelle]

The camera is placed in the scene, not spawned?

[trim matrix]

Yeah, it's placed in the scene

[dawn gazelle]

So that means it can still exist before your player 2 is created.

[trim matrix]

Player2 is created on gamemode beginplay

Scene objects would really load in before gamemode is finished executing?

I guess the 'handle new player' event could be firing after the camera is loaded in

Would it be more accurate/work if the logic was placed in the level blueprint instead of the camera blueprint? I can't really think of another way to reference player 2

I should also note that even the 'tick' event doesn't print p2, even after some time has passed making me think it's not actually being set.

[faint pasture]

Make or hook into a Player added event on GameMode or GameState, have that event notify camera to recheck the player list

[zealous fog]

I've found that YouTube isn't the best place for tutorials on proper code lol

Except for the unreal channel which is actually really good

[trim matrix]

@faint pasture One that is triggered after p2 is created?

[zealous fog]

YouTube tutorials can help out grasping the basics or giving you an idea for how to do it but it's not how you would write blueprints if working on a large game

[blissful grail]

I think you'd be quite surprised at how often perceived bad code makes it into the production code of a large game that you might be purchasing.

[trim matrix]

^ If that weren't true, you wouldn't see extreme issues like Battlefield 2042 and Vanguard.

[dawn gazelle]

I'd imagine that's because of time constraints more than anything - someone set something up quickly to get it working with the intention of refactoring it later, but never got around to it.

[umbral ginkgo]

Im trying to make this so this can only happen once using the "Upgrade 1" bool. Any idea why its isnt working?

[blissful grail]

Yes. That's how it always is. That's why there is that mantra that "temporary code isn't"

Prototype code - more than likely making it to production code.

[trim matrix]

Yeah, I make it a habit to refactor as I go. I guess that's why it takes me so long to get things done.

Godot is fine for some games, not others and UE fills in the gaps.

Just depends on the project.

[vale pine]

Am I setting myself up for an eventual optimization nightmare by making a blueprint-based character controller (capsule controlled on Tick by adjusting velocities, ground/wall detection, etc)?
Or do people do that all the time?

[uncut lark]

Right so no weapons, etc etc, right?

Is this applicable to soft saves and hard save states as well?

[faint pasture]

Is Godot's scene heirarchy as cool as it seems?

[faint pasture]

If you destroy and respawn the character, it'll just be at default state. If default state is full ammo and all 4 weapons then that'll be what it is.

[faint pasture]

You're basically rebuilding CMC with maybe 1% the performance but go ahead.

[blissful grail]

In my opinion, yes. It's one of its strong points. A big advantage that it has, that people don't think about, is that it has a very deterministic call order. So you know exactly when an initialization-style function (such as _ready, equivalent to BeginPlay) is ran.

You know which node is getting the current tick call as well.

But if you have questions about Godot, you can shoot me a DM. Don't want to clutter this channel with too much Godot talk.

[faint pasture]

I'm working on a highly modular vehicle building game and the multi layered scene heirarchy looked interesting. Shame the 3d and physics isn't as far along as hoped.

[vale pine]

My reasoning is to make a character orientable with a varying gravity vector, although maybe I dove too deep into that pool before figuring out if CMC could do it as well.
Basically this:

can i set actor location and have it so that it wont move into an object with collision

so no player index 1 I assume

[meager spade]

Hmm, you'll need some way of accessing the second character

I dunno about your setup so hard to tell you a good way of accessing it

[ruby cobalt]

yeah I understand

I actually need two players (split screen) and I think player index 1 would work with the 2nd player

I think if I apply the change in the player blueprint it would work but idk how to fetch the data

i wish I understood better how the created players stuff works

yeah when I enable splitscreen, setting player index 1 affects the 2nd screen so that's not bad

[umbral ginkgo]

What should I use as object? Spawn box trigger is a class but there's only one of the actor in the scene.

Get all actors of class or get actor of class or make an actor variable that is public by clicking the eye looking thing and in the world directly reference the object

Hello, I got my third person character to hold a pistol but now I have no idea how to make it shoot. I've searched through the internet but still don't understand how I can make the projectile shoot out from the pistol.

thank you, this was my solution, the last thing you forgot to have on there is adding the actors location back on after you rotate it....why isnt this just built into that node by default?

[oak timber]

the node is meant to be used locally

[frozen spear]

yeah, the box i was grabbing the extent from was inside a BP

[oak timber]

No origin is always zero you convert it to world getting the correct location/rotation

[frozen spear]

...no?...i was agreeing with you...ill rephrase..."yeah i see that now, the box i was grabbing the extent from was a child component in a blueprint"

yeah but if you want to convert it to world space you do like so

[brazen merlin]

should be the same as it has always been - through cmc - im on 4.26

[dry stone]

Yes it works in the previous version but in my current version when I set the jump velocity in the character movement tab it remains completely unaffected.

[brazen merlin]

well............. it shouldnt

[winged sentinel]

Is it possible to destroy and AI but leave its body on the ground

you try big numbers?

Look at how the first person project does it.

[dry stone]

@brazen merlin Yes indeed!

[granite copper]

Okay I will take a look at it

Yes, in 4.22 I can set the same character's jump velocity and the velocity changes, in my current version it doesn't. 😦

Is there some world setting that is wrong?

[dry stone]

Yes!

might be some weirdness between versions

not sure how you can "update" the cmc

[dry stone]

It is compatible with my project.

sorta right?

maybe you can verify engine or restart i dunno

QQ, is there a way to get Actor[Begin/End]Overlap event fired on Blocking Collision?

[brazen merlin]

probably want on hit

be sure to check the box

[dry stone]

No problem, solved it! I was using the wrong version of my character, there we're two of them with the same name! 😄

[lyric relic]

I wanna be able to detect End too

[brazen merlin]

well.. who woulda guessed that

[dry stone]

@brazen merlin Thanks for the help! 😄

[brazen merlin]

the point of block is that, so there is no entry

otherwise it is the overlap events, if one of your objects overlaps while the other blocks

[lyric relic]

my use case is: using a physicsHandle I wanna make it know if the object grabbed is hitting something or not, to tweak the strength of the grab (coz objects jitter when they hit a blocking object if force is high, and can even pass through) and drag slowly if force is slow when there's no blocking hits.

[brazen merlin]

reference to a game that does this?

[lyric relic]

I think I'll use a timer to detect if hit events has fired in the past x seconds

I mean knowing if an actor is currently colliding with something or not, is a useful thing for many use cases, even VR

[brazen merlin]

if its something like a sphere collider, then on the hit event, you could measure its distance and compare against it's radius to see if it is farther than its radius

[lyric relic]

I dunno what other games do that, but in my game, if my physics handle has low forces item moves around slowly (so I need to increase forces) but when I do that Item jitters when hitting an object

[brazen merlin]

#legacy-physics is your best bet

[lyric relic]

Thanks! will check it out

[junior citrus]

How can I track a crash after a change in a Structure?

[brazen merlin]

suppose from the logs

[junior citrus]

It's weird, my Unreal says a lot of things related to a D:\ disk, but it's the partition reserved for the win10 system

[ornate linden]

Is there a way to take an existing character blueprint and make an abstract class for it? Like I made 1 npc character, but my codes getting more complicated and i need to make the npc character a essentially instantiation of a abstract npc character class. so i can cast any type of npc character to the npc character abstract class, etc.

[round shale]

@brazen merlin literally the dumbest reason i kept having issues with the line collision lmaooo i put the line at the wrong coords so it didnt go anywhere

but it works now 😁

[ornate linden]

For my question I just ended up changing the name of my npc, and removed the "hard-coded" values i had for that npc and now it's just "abstract" in my mind. then I just made a new bp and used my "abstract" class as it's parent. not sure if that's the right way to do it, but seems to work for me

[gentle urchin]

Sounds like a solid way to do it ^

[obsidian moon]

hey guys

Does anyone know why z kill doest respect pawns when their world position is updated via actor world offset?
Am I missing something simple here?
Characters, simulated static mesh actors or any pawn with any type of movement component seems to fire z kill
If simulated or updated via movement component
But if you tick or timeline a pawn base it doesn’t destroy when passing z kill

[trim matrix]

Hey guys, I was wondering if it's bad to make an array with 500 elements ? would the game crash at some point or it's all good ? It's for a raffle system btw.

[obsidian moon]

@trim matrix your fine with 500 array elements

unless its like a blob datatype running on a toaster

you should be fine

[trim matrix]

thanks for the quick answer 😉

[obsidian moon]

no worries

I'm assuming its a standard data type?

if your doing a 500 array struct

[gentle urchin]

Are you moving the entire actor? Not just a component of it, right?

[obsidian moon]

its really an array of an array at that point

@gentle urchin correct

[gentle urchin]

Is this some flying mechanic?

[obsidian moon]

Easy enough to test

I'm working with the VR template

made my own custom movement component and added a gravity function

my game isn't complicated enough to really need to go with a full blown character class

[gentle urchin]

so its a child of pawn

[obsidian moon]

its a pawn yes

parent is pawn

in my component on component tick

I'm running a gravity calc

[gentle urchin]

killz at -100

[obsidian moon]

my kill z is at -2000

[gentle urchin]

look at my pawns location

-6k

still alive

[obsidian moon]

yup

exactly

it doesn't respect kill z

[gentle urchin]

Lol

i misread the problem

i thought you wanted it to ignore it 😄

but

cant you just manually check killz ?

you're doing manual gravity anyways so not exactly a big extra step

[obsidian moon]

how would I check killz?

can i get the world kill z value?

[gentle urchin]

Not directly, youd have to make your own

[obsidian moon]

and compare current z loc to it?

[gentle urchin]

Yes^

[obsidian moon]

well that's hogwash

[gentle urchin]

Iirc its not exposed to bp

[obsidian moon]

why do i need to make my own when its a world setting

[gentle urchin]

Bet its accessible in c++

[obsidian moon]

there is a kill subsystem

there is a getworldsettings too

but I don't know how to ref world to feed it correctly

[brazen merlin]

@obsidian moon what is the root component of this thing?

[obsidian moon]

yeah world is out of context as it requires some capture object

@brazen merlin my root component is a scene

but I've tried a capsule collision copied off the character with no luck

you can do the same with a static mesh actor as well

[obsidian moon]

that doesn't matter

[brazen merlin]

on a different note, you should not destroy your player character

[obsidian moon]

what?

z kill destroys your player character

thats what it does

[brazen merlin]

it will respawn them

[obsidian moon]

you then get gamemode -> restart player

[brazen merlin]

but it does call OnDestroyed

so you can check to see if that gets called

[obsidian moon]

yeah if you have a default pawn set

in networking you manually do this

as only the server can spawn clients

[lament ginkgo]

Hey question - if I call Launch Character with a Z velocity, then have a check for Is Falling on Event_Tick, is there a world where Is Falling would fire on the same frame as the launch and therefore return false?

[obsidian moon]

your logic won't work with replication

[brazen merlin]

ah, no it wont, and i did not know this was mp

[brazen merlin]

is falling is when the player is in the air, so it would fire as soon as they get launched or jump

[obsidian moon]

but yeah @brazen merlin a static mesh actor "root component" is the mesh

the mesh fires overlaps

and blocks all

[brazen merlin]

ah, thought you said it was scene comp

[obsidian moon]

yet this same logic will not fire kill z

kill z seems to only respect "actors with movement components or simulated actors"

actors or any child actor without movement components regardless of the root component will not fire kill z if updated location is via actor world offset

[brazen merlin]

thats my familiarity but ive also overheard kill z does not "work" with mp but i dont know if thats correct

[obsidian moon]

it does

[brazen merlin]

it should right?

[obsidian moon]

I have a VR game right now that is built off "character class"

[brazen merlin]

so its just the uniqueness of your setup?

[obsidian moon]

kill z fires

[lament ginkgo]

Ohhh I see what the issue is - Launch Character doesn't apply velocity until next tick

[obsidian moon]

character has a movement component

pawn does not

I don't like bloating my projects with unnecessary components that handle tons of logic for something as simple as "move this actor here" or "calc gravity"

the movement component is amazing .... but way too complicated for what I'm doing

[brazen merlin]

im not a fan of bandages either

[gentle urchin]

One would expect pawn to react to killz aswell by default

[obsidian moon]

I can literally save tons on the cpu on a quest build by using a pawn vs full blown character

hell the VR template itself uses a pawn

when you open the movement component cpp its literally a trace executed in line with input vector to find the floor

add in gravity

[brazen merlin]

sounds pretty good

[obsidian moon]

that's what I did

minus the 15 different modes, settings for everything under the sun

[brazen merlin]

so does your pawn have physics enabled?

[obsidian moon]

my pawn has physics constraints for hand and gripped objects

but no

[brazen merlin]

id imagine physics actors can register with killz since non-physics assets dont move so i figure they're excluded

just trying to rationalize why your pawn wont register but actors in general do

actors with physics fall so i assume its linked

[obsidian moon]

huh?

actors -> pawns-> characters

[brazen merlin]

right

[obsidian moon]

no actor respects z kill

without a movement component

[brazen merlin]

it literally says it destroys actors

[obsidian moon]

a pawn is a child of an actor

[brazen merlin]

and id imagine falling phys objects should be cleaned up instead of fall forever

KillZ: "any actor falling below this level gets destroyed"

[obsidian moon]

when you simulate a static mesh it doesn't simulate the actor

unless the mesh is the root

the actor will remain in the world

if you simulate the mesh "which is the root" then yes

depends on the actor setup

but a pawn which is an actor can't simulate at the root

I mean it can... but all its children will break away

wouldn't make any sense

would be like simulating the root capsule on a character

he'd go glitching off into oblivion

[obsidian moon]

exactly

which is why I'm here saying that it doesn't appear to do what it says

[brazen merlin]

yeah, right, and im thinking its because physics isnt on

[gentle urchin]

Wouldnt be the first time

[brazen merlin]

why check a static actor?

[obsidian moon]

actors aren't static

they literally have "movable" by default if a pawn class

[brazen merlin]

actors can be static....

[gentle urchin]

Cant find any info about a kill subsystem tho? Are my googling skills that bad

[obsidian moon]

actors are "all objects in the world"

you know that right?

[brazen merlin]

oh you know what i didnt

[obsidian moon]

an actor is literally the parent class of all things in the world

movable or static

each child has a class default

pawn which is an actor is "movable by default"

which is why it doesn't yell when you send it an input vector or add actor world position

@gentle urchin its "auto destroy subsystem"

I thought it was something else

it looks like a way to dig deeper into actor life span or destroy functionality

[gentle urchin]

I see. I thought it was something else aswell by its description

@obsidian moon

seem to work

[obsidian moon]

@gentle urchin yes sim physics on a static mesh root will work

but you can't sim physics on a pawn

expecially if your "controlling" it

and if it has child components

as they will "tear away"

but I did figure out a way around the issue

I got the world settings in my custom movement component

on begin play

stored it in a var

pulled get z kill

[gentle urchin]

I see

[obsidian moon]

then compared it to the z after the gravity calc

if it was less than the z kill i destroyed the owner of the component

and kill component tick

so it wouldn't continue to try and calc velocity or gravity and give a null pointer

but yeah I looked into the cpp side as well

https://cdn.discordapp.com/attachments/221798862938046464/923115675470413844/unknown.png

This def looks like it should work

[gentle urchin]

I dont see why it shouldnt really

[obsidian moon]

its not using collision

its literally comparing z just like I'm doing here

[obsidian moon]

Literally the same logic

[gentle urchin]

ah

the component is responsible for the check

interpto component

[obsidian moon]

yeah

which explains it

why an actor or pawn won't fire it

[gentle urchin]

Yepp

[obsidian moon]

without an movement component or a simulated root

so yeah

I had to implement the check in my custom component anyway.

or at least return !CheckStillInWord() in my component

just stuff like that isn't readily exposed

Gotta do crap like this

haha

[gentle urchin]

Sometimes I wonder if they're just lazy not exposing it,

or if they do it with intent

to gate people into doing specific stuff in cpp

like a movement component. It should be driven on tick, and surely benefits from being done in c++

[obsidian moon]

yeah I'll likely move this over

probably should have started there

its just so basic right now

but this function I surely will be adding very soon to my project module

         if(GEngine) return GEngine->GetFirstLocalPlayerController()->GetWorld()->GetWorldSettings();
         return nullptr;
 }```

Just so I can grab worldsettings alot easier

I think this will work too?

if(GWorld) return GWorld->GetWorldSettings();

[gentle urchin]

return GWorld ? GWorld->GetWorldSettings() : nullptr ; 

[obsidian moon]

but yes.... i usually prototype out and move all ticks over to cpp

[gentle urchin]

makes sense

[obsidian moon]

I actually already have the cpp component made

[gentle urchin]

bp wins the proto race

doing the same really. making the systems initially in bp, then moving them over to c++

[obsidian moon]

just always really fast to make an actor component and go ham with it

lmao

[gentle urchin]

being brand new to c++ it's alright to have a base to go off from 😛

[obsidian moon]

yeah the thing I keep forgeting to do

is create a cpp class first

then make a bp child

[gentle urchin]

you can always reparent

I did that for my classes no problemo

[obsidian moon]

then move from bp into parent

just one of those things you learn over time and keep forgetting

like darnit

[gentle urchin]

i did a few mistakes doing this tho. Naming the c classes horribly

and it haunts me every damn day

Also since this is my first conversion project, i wanted to keep function names more or less identical to the original, so i could keep tabs on what i've done and not (and replace in bp while i went along before deleting it all)

so now they're prefixed with c

rip

[obsidian moon]

So if I need to grab an enum I made in engine

in my component

in bp its pretty easy

but in cpp I'm like htf do i get it

lol

[obsidian moon]

still learning little stuff like that

[gentle urchin]

Yeah i still have a lot to learn really

just recently discovered bpgetters and setters,

and i sort of want to use them,

but then i dont really want to, because it just hides code from the user?

[obsidian moon]

lol

the good ole double edge

gotta love it

[gentle urchin]

    UPROPERTY(EditDefaultsOnly, BlueprintGetter = GetHealth, Blueprintsetter = SetHealth, Category = "User defined settings")
        float Health;

void AC_Master_Placeable::SetHealth(const float Value){ Health =  Value >= 0.0f ? Value <= MaxHealth ? Value: MaxHealth : 0.0f; }

Like this one

[obsidian moon]

the more i improve with cpp the more I kick myself like "where the hell is this happening"

[gentle urchin]

Auto clamped, but i got no way of telling anyone about it

[obsidian moon]

and yeah

sometimes you gotta expose a returned function just to "Show" something

or have a public var in some category

so they can see its getting updated

[gentle urchin]

Yeah

But like, in this example ,

it's alot more obvious to the guy doing the bp

if "set health" or "update health" is a function call,

and not just a "set health" like a regular variable

[obsidian moon]

yeah i don't have "set health"

[gentle urchin]

set health could be anything really

[obsidian moon]

yeah i get you

[gentle urchin]

it was mostly to test if it was what i thought it was,

[obsidian moon]

and usually all my math functions are =/-

[gentle urchin]

and to see if i atleast could expose some comment to the bp

[obsidian moon]

+/-

its a plus value that can accept negatives

and clamps at 0 / 100

less code

lol

[gentle urchin]

less is more, i've been told

[obsidian moon]

it is

😄

[gentle urchin]

readability has a value aswell tho

[obsidian moon]

I've also changed to interfaces across the board

and slam a return in

for function overrides

😄

make it very very easy

no more casting and hard refs all over

and huge huge dependancies and memory chewers

doing VR games that have flat support that literally have 2 classes for most things

slam a player interface in there and fix that

and a controller interface

pretty much handles everything you need
