@storm terrace 1 unreal unit is a cm
storm terrace
so here does that mean I have 121meters by 121meters ??
so 12100 cm by 12100 cm?
is that correct? based on the screenshot
quasi scaffold
unreal unit, not vertices, the snap is in unreal units, if you set it to 100 and move items around, you'll move them meter by meter

is there a way i can have it so certain players will have a certain pawn from platform username or something like that

Hi, i group a bunch of objects but how do i select the individual piece besides ungrouping?
abstract relic
Going off of that. It would be (overall resolution -1) * 100 = Xcm

@lament basin ctrl-shift-g to toggle individual selection?

Hey guys- anyone using the in-engine code editor plugin? How do you feel about it? Is there any way to modify it or customize it?
scarlet birch
@barren flume There's events you can override or you can just spawn a placeholder pawn and then pick a new spawnpoint.
barren flume
not sure how
or which
should i put in level blueprint
for when the player joins
scarlet birch
Read through the network compendium. There's a find spawn or something that's overridable.
FindPlayerStart it's in the gamemode
It's worth looking through all those and seeing what's all called and when.
scarlet birch
You can use a tag on the playerStart and then override FindPlayerStart to find the right one.
barren flume
what kind of tag
I see player start tag
oh i know
i think
do I put the other player start there
or I could have a pawn in the game already
and when the certain player joins it can possess it
okay i got the possess to work
i just need to figure out how to get the username
i know about that get platform user
but that's it

thin tendon
Is there a correct method for getting the edges of the viewport for a widget? So I can lock it inside the viewport.
whole quarry
Widgets are generally already using the viewport resolution
Its the components you want to lock inside the viewport I guess
thin tendon
I'm creating a system to simulate a mouse. Using a widget and a gamepad. I have everything working I can move and click on buttons. But I'm having trouble telling it that it can't exist outside the screen
thin tendon
Its to add gamepad support without using the focus system
honest vale
FXAA does smooth edges of objects so that might look blurry to you

There is a node for "Is in viewport" but it does nothing
Its all good I figured it out. lol It was my fault I had a single node out of place

rancid lynx
if both of these are running every single frame. with 100 actors each. (For example), does anyone know which one uses more or less CPU ?
if they both run the "math" 1 time each frame, are they equal in cpu ? or is the timeline cheaper perhaps ?
ive read that timelines eat a little extra ram, so eventually that would add up. so im trying to understand best cheapest practice.
i could do 10 times a second inside a timeline, or a event tick, timelines require more ram, so if they are not cheaper on the CPU, we may as well use optimized ticks. i assume. ive only been learning google search trash for 1 year.

Hi,What could be a setting in blueprint details that make an Actor undestroyable when Destroy() is called on it??
All pieces inherit from a single class named APiece, the child classes have a description of how the piece should behave(for example move);All the pieces behave correctly, except for the knight, that won't destroy when Destory is called on it...Anyone knows what could be the cause?
tacit onyx
There shouldn't be a setting for that. Not that I've ever been aware of anyway. The only way destroy should 'fail' is if the actor is already pending a destroy. Is the knight's destroy functionality in any way different? How are you calling it?
thin mantle
I'm getting it's reference before start,and as for all the other pieces, when I need I call Destroy() on it, the code is the same for all of them
unreal sonnet
@rancid lynx Anecdotally, I've heard that Timelines are a bad practice to use in bulk, and that you should try to avoid them whenever you can.
Doing a line trace hundreds of times every frame is also bad, though, so if I were in your shoes I'd try to come up with some out of the box solution that won't be as accurate or good but will avoid all of that processing stuff.
I can't think of a scenario where you'd would need to do it that way, so hopefully if you brainstorm a bit you can find an alternative solution!
thick herald
Line traces are fine to use in bulk.
unreal sonnet
Yeah, don't take what I say as gospel. I could be wrong!
thin mantle
Solved my issue by deleting the knight blueprints and redoing them,now,idk why,knights work correctly
thick herald
@plush thicket you don't have a branch checking for the false print string, it will always say false.
plush thicket
Can you give me a mini example of what I should do to fix that?
fallen elbow
so im using world composition, in which level do i need to use it?
thick herald
I'm not sure what you're trying to do, but if you're needing to do something if 'is sensor hit' is false, just add a branch and check, just like you did with the true branch.
harsh tiger
how would i determine if the output is odd or even?
unreal sonnet
I would make a "Math Expr" node and in there I would type X % 2 == 0. It will give you a red boolean pin to say (true=even, false=odd)
And then you plug your thing into the X pin
harsh tiger
perfect. just eating my dinner atm. will give it a go shortly

harsh tiger
@unreal sonnet i created a math expr node but its read only so i cant modify it?
i done this and its worked just fine
unreal sonnet
I think you weren't using the Math Expr node correctly -- instead of typing "X % 2 == 0", you appear to have just typed "Is Even"
harsh tiger
ahhhh, i've never used meth expr before. i think i know what you mean now
that's super cool! i never knew about math expressions before
whats the difference between that and
unreal sonnet
There you go! ๐
The difference is convenience. I don't know if there's a performance improvement
harsh tiger
ah okay, it is a lot cleaner than my original method. i guess if the maths was more complex it would be a lot cleaner than having multiple nodes everywhere

Is there such thing as a lighting render bug? I have 6 spot lights in a decent sized room and when I lower the candelas from 80 to 60 on all them and hit the build button it stays the same brightness after the build is done.
Found a way around this issue above. Not sure if its a known problem in the engine. FIX: go to each light source and uncheck "affect world" and hit the the "build" button. Only way to get lighting to update in the room. After that, I rechecked "affect world" with the new lighting numbers and hit "build" again.
unreal sonnet
I think there is a built-in engine limit to how many lights can affect a certain place at the same time
Try deleting one or two of the lights or moving it someplace else, then rebuild and see if that helps @brisk urchin
sturdy star
maybe a simple/stupid question, i'm trying to create a method for rotating an object based on camera position/rotation, where you can only rotate around the cameras Up Vector and the Right Vector - eg: can spin a cube left and right, and "forward" and "backward". but the two shouldn't interfere with each other, the rotations happen independently of each other. for the life of me i can't get it to work as expected, i can get either one of the rotatiosn to work but not both at the same time without things going screwy - this is in bluepritns btw
frozen pond
can static mesh instance be added in world space ?
brisk urchin
@unreal sonnet I see, I didn't try moving the lights. I did change the attenuation, which didn't do anything with the issue. It's just weird because that room is almost identical to another room near but the other room has no issues with updating its light settings even they they both have the same number of lights.
unreal sonnet
I know that the lightmap has a "resolution size", so instead of X number of lights affecting the same spot it's X number of lights in the same 100x100 square area... maybe your lights are overlapping too much in that 100x100 or whatever square area. ๐คท Just pitching ideas

I feel like an idiot. ๐ I believe I know figured why my spotlights weren't updating after building. My six spotlights all had an 89 outer cone, 800 radius and 50 candelas. I would tweak those stats and nothing would happen and rebuild.
I then noticed that all those lights had an inner cone of 0. Once I raised the inner cone value the lighting was finally changing after build but not before then. This is probably why right??

Hey, guys. Is it possible to do something like this on an unreal engine? Do you have any ideas how to make the enemy grab for head?

yes it is possible. the head can be a socket or bone for where you want the hand to match up with. Then you can play the animation of the grab and move the character as needed. Chances are for something like this it could even be scripted using sequencer

Wasn't that game made with the Unreal Engine? If so, then yes by definition it can be done in the Unreal Engine.

There's something else, though. Are there any special camera or scene capture actors in your scene?

I dont think its flipping over the origin, because I can see pictures that are supposed to represent objects, and I think the camera is properly moving around them
reef lava
This is copied and pasted from another dev server I'm active in but here we go: Ok so, tough question, as it's quite generic and could have a lot of contributors, but I'm running 16gb of DDr4 ram with an NB freuqncy of around 3600 each right, and every time I open my main project, I'm getting a little over 80% mem usage with one bp tab open, even with it closed (all tabs besides the viewport and message log), it occurs, so is that normal? I mean the map I have open at start is nothing short of simple. It's dev testing map with nothing but a very crude landscape, and bps that run in real time, not editor code.
really suspecting a heavy mem leak in this project, but I haven't a clue where to even start anymore...
midnight root
crude landscape you say, but are you using raytracing and what else is on landscape ?

I have a dumb question for ya: If I make a Third Person project, is it possible to make it a first person only game down the line? Or is it locked to third person for some reason?

@plush yew doesnt matter you can move the camera after
plush yew
ty
hollow ridge
I have a question. It says I am generating an infinite loop. It shouldn't be infinite tho cuz every time it happens I add one and then I stop it after it gets to 10. Is there a way I can bypass the check? is that a really bad idea?
wind gale
@hollow ridge Can we see the offending code/nodes?
hollow ridge
It is very simple I am just spawning an actor that spawns more actors Ill send a screen shot if you want
wind gale
ayup
wind gale
Is the Room actor spawning other Room actors?
hollow ridge
yes
but it is adding in a different actor so they all are adding to the same vlue
value
wind gale
How do you determine which Room's RoomsCreated property to reference?
hollow ridge
no it is in a different actor not one of the rooms
wind gale
is your comparison there correct? Do you mean to check greater than or equal?
hollow ridge
that is greater than or equal right? also it wouldnt matter cuz if it were the wrong one nothing would every happen because the default value is 0
wind gale
can you scrunch all these nodes next to each other, so you can make a screengrab of the whole graph?
hollow ridge
um not really cuz there is a lot more than just that
I am doing all of that 4 times
wind gale
I don't have enough info there... I don't know where these wires go or come from.
wind gale
If you have an event calling itself in the same execution without some sort of delay or limiter, you'll get an infinite loop.
oh, new pic... standby
welp... it's a nice arrangement of wires... but without the words on the nodes... can't make heads or tails of it
wind gale
so, it is probably that particular actor being spawned is either not feeding in the value used to limit the loop of the execution, or it is calling the whole event again in the same frame, or it has its own loop of some sort within it that is not being allowed to escape.
hollow ridge
oh its cuz I am running it 2 times and choosing a random one of the spawns so there is a chance it will end
ok

crude landscape you say, but are you using raytracing and what else is on landscape ?

WELL depending what else you have open, and which version of ue4 you're using, could be a memory leak I suppose as that sounds way too high for something simple in nature

is there a command that can toggle cull distances?

what else are you running while this occurs
reef lava
and for some reason, speaking of versions, it doesnt allow me to compile from source on 4.24 (which is kind of not part of my whole ordeal since it's not a priority i switch yet), but weird thing is it's not even a code project rn.
as in other apps?
midnight root
yes

discord, spotify, thats it

reef lava
cant. doesn't let me switch, because when I do, (and this is the weird part) despite rebuilding in VS and rebuilding the source from the project file, it fails upon doing so, then telling me it failed to compile the source file, when my project contains no C++ in it yet.
midnight root
errors ?
reef lava
building inside of VS succeeds, but proceeds to fail on opening, resulting in the same failure to rebuild it's source
reef lava
there are none, ( may be in some logs havent checked the most recent ones yet) but it's a source rebuild failure

no idea on that my strength atm isn't in coding

I've set up online games across North American servers using steam but that was years ago, but is there a specific service you have in mind to use for server setup?
reef lava
it doesnt necessarily, it will just be granted the dev ID, which is space war or some crap i think dont remember entirely though, the last time I actually did any network testing through steam was prob a few months ago, when I had it on there privately for testing purposes.

if you look into pyro dev's tutorials on steam functionality in ue4, they're pretty useful https://www.youtube.com/watch?v=ke3kmK6bvT0 I'd certainly look into them if you're interested in trying that sort of thing ๐ @barren flume

@supple totem I suppose you don't have custom shader code
And that you're not doing custom render stuff
supple totem
nope just stock 4.24
silver crown
Is it only on your machine
supple totem
testers too
silver crown
All this is telling you is that unreal did something wrong with the GPU
But could also be the GPU being faulty (unlikely if reproducible across different machines)
Or the driver being faulty (also unlikely)
Not something you can fix on your own besides trying simple stuff like switching to windowed full screen or real full screen
Could be worth trying the 4.25 preview as well
See if it's fixed in that
supple totem
yeah I'm messing w/ windowed and fullscreen now
and I agree it looks like a deeper issue than my game code

Hi guys, i'll be greatly appreciated if someone could explain the world composition layer's intended usage? I'm interested in - can I stack one level above the other in the wc setup and increase the layer number. F.e. one level holds only geometry, then the other level will be placed above it and will be holding some logic, and the other, placed above - will be holding some effects \ lighting \etc.
thick herald
Not as far as I know, it's purely for actual map tiles. You do get some degree of control if you enable landscape layers though.
smoky latch

@cyan robin the best way would be to use blueprint interface i think, check the docs on them
Not as far as I know, it's purely for actual map tiles. You do get some degree of control if you enable landscape layers though.
@thick herald but you actually can have one tile above the other (f.e. landscape and underneath - dungeon), for this you'll need to setup layer number appropriately - so you could select in wc preview window correct tile. Then in dungeon wc tile you could simply set the visibility of landscape tile to "hidden in game\no collision" and here you'll have a landscape tile (for example - x0y0) above, and tile with hidden landscape and dungeon geometry but on tile x100y100 below
thick herald
Yeah, it's possible to have all the tiles stacked, but for what you were asking ie having each tile contain different parts of a level.. it's not really what it's for.
Maybe if you explained why you want to do this?
smoky latch
Yeah, it's possible to have all the tiles stacked, but for what you were asking ie having each tile contain different parts of a level.. it's not really what it's for.
@thick herald i want to separate logic and geometry, f.e. i have one big tile with logic, and underneath - 9 smaller tiles with geometry to save memory. So to have only 4 of the on lod0 simultaneously
thick herald
Sounds like you need level streaming, not world composition
smoky latch
Sounds like you need level streaming, not world composition
@thick herald i thought that you cant use world compositiion and streaming volumes simultaneously - it's either one or another setup
in some old stream on level streaming - that was said, don't know maybe now it's different?
wc is very convenient for landscape
merry gazelle
anyone else agree the play button should be moved over to the far left? It's really annoying on small or split screen that it gets hidden
thick herald
I think that's still correct it's one or the other - I don't know for sure - I guess you could use it for dungeons and the likes if the streaming distance is set up properly. But as I said earlier, not for having different parts of the same levels stuff lights/geometry. Having something hidden doesn't remove it from memory it's still there. UE4 doesn't render things that are not in view anyway, but they are in memory.

UE4 doesn't render things that are not in view anyway, but they are in memory.
@thick herald if you are referring to hiden land tile for above lvl - it's memory cost is nonexistent - it doesn't renders = there is no vram cost\no draw call, it has no collision (also reduces memory), but on the other hand it's a big timesaver - you'll need to setup logic for one level instead of 9. And then in this 9 lvls you could save a lot of memory by reducing the meshes\textures amount per level, and increased level loading speed - i have already tested all of this, memory save is ~200mb on vram, and 2mb loss on ram. BUT the loading logic for wc tiles is that so if you are moving from tile 1 to tile 100 (f.e. they are near each other ) - some logic needs to be processed for other 99 tiles - so to get from 1 to 100 it's not that simply.
gains in my case
but the question stays - is it intended to use like that - there is wc layers that allow for such use, but what will be this transitional cost between tiles - I don't know
thick herald
I've said already, no it's not. Do I know for sure? No, but I've not saw anyone suggest it the way you are wanting to use it.

@heady quartz you can add\remove landscape components, check out Epics landscape stream on youtube, or landscape technical guide doc
so your land doesn't need to be square

is it okay to add tons of landscapes to fill the areas?
i want it to be square
i want flat landscape to paint textures in them

smoky latch
it's your choise, you have options
1 add land component to tile
2 add separete tiles
3 use world composition
heady quartz
which one is more optimized in your opinion?
smoky latch
which one is more optimized in your opinion?
@heady quartz for very large worlds - several square km and more- world composition. less - depends on many factors, target platform\specs\how many meshes do you have\how detailed do you want landscape tile to be
heady quartz
is using landscapes like this overkill?
or is there a different way to paint in dirt / grass / sand textures ?
smoky latch
there are epics streams on youtube regardin world composition and lvl streaming, there you can find more speific answers. I can't determine anything from your screens, there are no metrics
if the size of your level 1 km - ese single level

So I am looking to optimise my landscape material somewhat.
Currently I am using lots of material functions, each as a landscape layer. Rock, Grass, Dirt, whatever. Then blending them using a "MatLayerBlend_Standard"
Each landscape layer function is currently using 4 texture samples. Albedo, Roughness, Normal, Displacement. Just 3 channels each.
Would it be computationally cheaper to move the displacement to the normal alpha, and the Roughness to the albedo alpha?
Or should I move the displacement to the albedo alpha and use the R channel of the albedo for approximated roughness?

why does ue4 compiling shaders everytime i modify something? it takes a lot of time too.
saving, changing, importing, modifying everything takes loots of time, its unusable
:/ does that happen on every game engine?
(trying to import 84 objects, and its compiling 9400 shaders)
abstract relic
Yes
royal crest
how can i speed up this?
and material editor previews are very slow too. in blender i can modify materials much faster.
abstract relic
Break down the material if youโre experimenting on new functions, make material instance if you just want to adjust values, get more ram.
normal burrow
Threads will help take the number down faster too
royal crest
which is more necessary? ram, cpu or gpu? i already have 10 gb ram i think thats enough
break down the material? threads?

I wish I could direct you to a hardware channel

Specific to shader compilation: threads. But each thread needs ram so itโs a delicate balance, and yeah sheesh

Right now, Material instance is going to be your go to from what I can gather from your situation.

grim ore
for your minimap widget, what does it show is the parent in the top right. What is the Slot
grim ore
yes. depending on how you set up your anchors will determine those values. It looks like you are using the Stretch setting so it will size itself to your offsets (full screen basically with offsets). you are not anchoring it to a position then setting a size like in the video
so you need to anchor it and then set the size, or you need to figure out your size and put it in

the material is not set for the correct permutation, you probably had it on a mesh first then moved it to a skm
in the material go to usage and either uncheck automatically and recheck it, or make sure the correct checkbox is checked for the item it is on.

is there any way to attach a player controller
to an AI pawn
I have a situation where I unpossess
a pawn
and he moves using pathfinding
but I want to keep him as my view target
rose wyvern
Hello this happens when i hit play in mobile mode. It flickers and the controller is tracing like this. But it works normal on device. Why? (epilepsy warning)
Wtf still flickers
maiden swift
Wow thatโs annoying. I figured it wouldnโt animate under the spoiler tag. ๐ค
grim ore
the player controller really doesnt matter for its location, it doesnt really physically do stuff like that
sonic pagoda
the problem i have is this
when i repossess
my pawn (that had been possessed by the AI)
he gets pushed back
to where he got unpossessed the first time by the player controller
grim ore
are you moving the actual mesh then and not the character?
sonic pagoda
the character is moving
with an ai controller
the player controller at this point is no longer controlling him
so when i repossess the pawn, i can then move around again (using my inputs and not AI move to) and when i unpossess him again , thats the location where the controller will stay at again
grim ore
welp the player controllers position shouldnt matter in terms of where the player is
sonic pagoda
ah its also because its networked
grim ore
then perhaps you are moving it on the client only
and when you repossess its now going back to where it was on the server
sonic pagoda
the thing is, i can't move it
when it becomes unpossessed
the controller itself has no movement once it becomes unpossessed from the pawn
grim ore
the player controller does not move when you move the character. The player controller is just a virtual thing that does stuff
its physical location is not connected to what it controls
sonic pagoda
i know it has a transformcomponent though
grim ore
so... what
sonic pagoda
im just going to have do it in c++ because its set to bp read only
grim ore
it could also have flashing particles, it doesnt mean anything
grim ore
when you unpossess are you doing it on the server or the client
sonic pagoda
server
grim ore
and is the AI running on the client or server?
sonic pagoda
server side as well
grim ore
then track the position of the character that is "warping back" every tick and see if the server is showing it correctly moving

It doesn't seem like nav mesh volumes are good for making more detailed paths. Am I wrong about nav meshes? or what should I google for something more appropriate?
like imagine you want to draw dirt roads on the ground somehow and that the AIs would have to stay on the dirt roads

Nav mesh isnโt a one solution fix all thing
lusty rampart
right, I just don't understand what other concepts exist so I don't even know how to start googling ๐ .
abstract relic
What people have done is make a pathing system. The ai will roam but it has a desire to stay along or near the path. How much it conforms to the paths is configured by you
Itโs what nav mesh does tbh
lusty rampart
is "pathing system" an unreal term? Or are you jsut referring to building your own pathfinding system from scratch?
abstract relic
But this gives more precision if you use it in conjunction
grim ore
you could still use nav meshes then make areas that are weighted more or less, your roads could be less for example, and then the AI would prefer to go on the road if it can
lusty rampart
@grim ore that makes good sense ๐
short vector
when you checked out the material the first time did it show used with skeletal meshes as checked?
@grim ore hmmm not sure what do you think should be the reason?
grim ore
If the material shows use with skeletal mesh and it's still not working you can look at the logs, perhaps the materials are not being packaged
for example if this material is not on the character all the time, say its a material that is loaded dynamically in code like a skin system, it might not be packaging

Hi, I asked this on multiplayer channel but I was ignored, so trying it here. I have a question. It a bad practice to use "Allow client side navigation" (in project settings) or is it OK to use it in multiplayer games? Is there anything I should know? Can it be exploited or etc..
I'm not finding much info about it. Maybe anyone here knows?

how did you set up multiplayer
I can't get it to work correctly
i'm using steam

Any idea why my nav volume doesn't show my spline meshes as being nav'able?
kindred viper
rebuilt the navmesh after you positioned the spline? If so, you can try adding the custom mesh bits as you would with things like holes you jump through etc. It might be an issue with dynamic stuff as any movement technically rebuilds the spline I guess
lusty rampart
@kindred viper I just added a non-spline static mesh to the generation, and those get added to the nav mesh just fine...
obviously that's not what I want, but I think it shows that the spline meshes don't play nice with nav meshes... ๐ฆ
which saddens me
storm terrace
how do I fix this error?
both objects are not static, they are movable
WheelMesh->SetMobility(EComponentMobility::Movable);
any ideas?
storm terrace
my actors are not null
they are complaining they are both static (when they are both movable)
lusty rampart
read the second link
storm terrace
dynamic_cast<UPrimitiveComponent*>(self.MassMesh),
self.MassMesh->GetFName(),
dynamic_cast<UPrimitiveComponent*>(self.WheelMesh),
self.WheelMesh->GetFName()
);```Is there a way to disable refraction per-material with raytracing enabled? For instance, I have a post process volume in a level, inside the volume is a niagara emitter for some dust motes. I also have a lot of glass in this level so ray traced translucency & refraction are enabled, however this pretty much breaks the particle and turns them into small refracted squares. I've done some digging around and haven't found a way to disable it per material. Am I missing anything or is this not possible?
storm terrace
@lusty rampart I wonder if there is a way to ignore this specific warning
this bug has been around for way too long (2017???)
terrible
lusty rampart
@storm terrace welcome to UE
storm terrace
is there a way I can make it work without the error?
even if it is more code?
I found a solution, the code must go in the BeginPlay NOT the constructor.
Can someone help me understand the difference from a UE4 perspective?
kindred viper
Constructor is made at creation time. Begin Play is when the object is ready for the world and to be interacted with
storm terrace
so in that case, it sounds like, guess BeginPlay first then maybe try the constructor if need be
abstract relic
Constructor is the best way to crash your project at launch. If your code isnโt airtight
And without Is Valid nodes
storm terrace
do most ue4 programmer just delete the custom constructor?
kindred viper
no?
storm terrace
and just use beginPlay
abstract relic
No
storm terrace
so when would you use it?
kindred viper
a constructor makes the object. You seem to misunderstand. Without the constructor, there is nothing but the shell of the object
begin play is the realtime event for when the engine decides its constructed and ready to use
storm terrace
so you can't just use
ConstructorName() = default;
kindred viper
not all objects need a constructor. the class type is already defined in that sense. It's more for filling in the essentials. ie. A character class has a constructor that adds the collision capsule as the default subobject. The character would still exist without the constructor (minus the code that references it) though.
storm terrace
oh
BaseScene = ubase.CreateDefaultSubobject<USceneComponent>(FName("Base Scene"));
still needs to be in the constructor because that needs to be made before game launches
I see

Hi all, I'm looking to get into learning Unreal Engine 4, however it appears that 4.25 is on the horizon. Is it worth downloading 4.24.3 or just waiting?
kindred viper
wait
4.24 has some issues fixed in 4.25. If you are starting out, its a good place to start
storm terrace
so components must be before it is spawned. so CreateDefaultSubObject must be in constructor is what it sounds like
kindred viper
yes
storm terrace
but modifying it goes in the beginPlay
so calling functions on it goes in beginPlay
that helps me understand
well all sets can't go in the constructor like the function SetConstrainedComponents
which got me thinking
normal burrow
@storm terrace @light lintel the construction script works at a time when the level is not made yet
manic garnet
@kindred viper Hi Marc, thanks for responding. Taking what you've said, is it worth the wait or would you recommend 4.25.P7? (sorry if I misunderstood!)
abstract relic
Still preview
kindred viper
@manic garnet I wouldn't recommend the preview, but if you are used to coding, there is no reason you can't start there. I would wait for the binary if you are absolutely new
normal burrow
@light lintel and @storm terrace are you talking about blueprint construction script or c++ constructor or c++ onconstruction?
storm terrace
c++ constructor
normal burrow
kewl.
manic garnet
@kindred viper Great answer, thank you! I'll keep brushing up my blender skills until then. ๐
normal burrow
c++ constructor: is not like blueprint construction script at all. the c++ equivalent of blueprint construction script is OnConstruction. c++ constructor is where you set up subobjects, components, default values. not more than that.
blueprint construction script and cpp onconstruction run at a time where you can register things for baking. so if you have an actor that genrates some procedural mesh for example in the constuction script, that mesh generated gets cooked into the level so the player doesn't have to do the expensive part of constructing it mathematically and increase load times.
just put it there tidiii
beginplay will run when the thing is made every time
kindred viper
that new blueprint baking thing is awesome btw
normal burrow
construction script for things in the level only runs in the editor
except when things are spawned at runtime, then those run construct scripts too
construction script is amazing yeah
hightide is right though, the engine is weak to crashing at that point
must be very ninja careful in there, thus why they don't let you create actors inside it.
@light lintel you basically want to use construction script when you can, you cant use construction script when you cant. which would be when you need to make another actor or search the world for anything but what the properties of the actor itself are constructed with
you can technically get past the limitation of not being able to construct actor nodes by putting things in functions, but this wont work and it will likely crash the editor tryin to invoke such thing in construction script. its completely fine to make components and add them to the constructing actor of course
so lets say you have a property for its size tidiii
and in the construction script you assign the radius to this size property on the actor
when you go to editor and change this property, you'll see the radius change with your changes to the size property
this is because the editor runs the constructor script every time a property is changed
through the details panel
if you had this in beginplay, you'd only see the change done when the game starts, adn it would be something the client would do when the level loads, it would save it with some other size, then at startup change it (with begin play)
so yeah thats the main difference, and constructor script wont run on cooked content, you'd have to use begin play to have any logic that runs on map start. think of construction script as mostly only aware of its details. you should not be looking in the world for anything inside it
nope
what i mean is, the constructor script runs in editor for things put in the level and then they are packaged
so things are packaged after the constructor script runs on them, which makes your level load faster.
the only time a constructor script will run on the packaged level is when it was something created at runtime
are you must making child blueprints for each weapon?
generally tidiii, if you can do it in the constuctor script: do it.
don't see any reason why you couldn't do what is in that screenshot in the constructor script
but sometimes you will run into things where yeah things wont work in constructor script, you just have to try. i'm pretty sure bounds is a grey area. but the transform of the object is a known at construction script time so.. try it i guess
you'd want construction script
it just depends on if you can have it or not
i'd think it'd be fine
if your using the mesh for overlaps, its probably using a capsule or sphere or box or something
check the mesh's simple collision
your using complex collision as simple?
if its using complex its just going to absorb hits and not be simulated iirc
will be slow to move
ah okay if its skeletal then your definitely not using mesh data
unless its convex
your likely using the phys asset for the mesh
yeah
