Yes I saved both, and even reboot unreal in case I still can't modify the child.

rotund scroll Mar 7, 2020, 4:04 PM

#

you can't modify inherited components

#

you can't change or remove the capsule because it's inherited

tired palm Mar 7, 2020, 4:08 PM

#

I see, it limits me a bit though :/ the components inside are also inherited.

#

#

I find it a bit odd, because the change in capsule size doesn't change on the parent, though.

abstract relic Mar 7, 2020, 4:14 PM

Child inherits from the parent. Parent never inherits from the child.

hey guys, ive been wondering about a shader complexity visualisation for a while now. it doesnt compile the material as seen in this example

📎 unknown.png

#

i know the material is not too complex or weird but just wanted to check. and seeing this, I worry something might break @ building

vocal copper Mar 7, 2020, 4:23 PM

I've made a screenshot describing my problem with generated mesh collisions. :)
Maybe someone has some thoughts on how I can get collisions to the generated mesh (is available only in runtime). Maybe I can copy collisions from the meshes I'm merging? What I should look for ?

Yes that's what I think too @abstract relic but the child "AICharacter" has the parent "ThirdPersonCharacter".

But as soon as I try to modify in the "Collision -> Collision Preset" part, it modifies both (whether I'm on the parent, or the child). What I want to do is just change the "Trace Responses" part of the capsule.

rotund scroll Mar 7, 2020, 4:33 PM

#

@tired palm you can change the values of variables, you cannot change variables themselves

#

@slender storm can you show your case

#

physics are really only enabled on ragdolls

#

collision presets themselves can exist on both capsule and mesh

#

yeah but enabling physics != enabling collision

vocal copper Mar 7, 2020, 4:35 PM

#

merging my customizable character (used in the lobby for a game preset) into a single piece mesh (used in game). When tested a customizable mesh in the game, the collision worked, now it only overlapses the capsule and that's all.. So I went investigating, found a mesh that is created in runtime and it has no collisions on it.
Going to check what ppl do while merging static meshes, I hope to find some answers there 🙂

rotund scroll Mar 7, 2020, 4:35 PM

#

there are different types of collision taht you can use for different things

#

for instance the CMC uses the capsule to figure out where the ground is, not the mesh

#

there are no other kinds of physics

#

there's that and collision

oops sorry, wrong account for the server, I wrote with both of them. It's kind of messed up in the discussion...

@rotund scroll I understand, I'll see what else I can do about the system then. Thanks

rotund scroll Mar 7, 2020, 4:40 PM

#

why do you have two accounts?

vocal copper Mar 7, 2020, 4:40 PM

#

but I don't have an access to it in runtime.. I mean, the mesh is created anew right before the game starts 🙂 Hence, it should be done on a merging stage, but I can't find what exactly I should operate with, to migrate collisions from the old meshes to the new one

#

@light lintel

#

generated mesh has no preset in the editor

Does having UE4 and its project installed on a certain drive give any benefits to like loading and rendering speed?? HDD, SSD, or M2 types or is it all cpu/gpu dependent??

ofc it will go faster on ssd

when i use blendspace and add interpolation. the character wobble to left. then move normally.sometime wobble to other direction.

how to fix this thing ?

i mean. when i move my character foward (that use blend space). it wobble first. either left or right.

@nova kelp my current 20gb project file takes about 8-10min when i hit the build button to update geometry and lighting currently.

nova kelp Mar 7, 2020, 5:34 PM

Btw when you use SSDs for stuff like this you have to have backups on HHD

What is a base colour texture like?

pseudo inlet Mar 7, 2020, 5:37 PM

You SHOULD definitely still be backing up to something else as well, but ssd lifetimes have gotten much better.

@tender flume base color textures are just that. Color information. No shadows etc

Albedo?

I'm sure there's some variation, tech ically, but that's what 3d software in general is going to call it. Base color and albedo

Each time I learn new things just by experimenting around and getting others opinions

brisk urchin Mar 7, 2020, 5:44 PM

#

@pseudo inlet doesn't that process usually have a notification pop up in the bottom right corner of the engine? My didn't show that. Unless thats something totally different.

pseudo inlet Mar 7, 2020, 5:44 PM

#

Not always, and certainly not when a new project is loading.

#

If the editor is already open and the project is loaded and you make a shader change, yes you'll see the message in the corner.

#

If it's a new project and there's not a DDC created already, on load the engine will begin compiling shaders.

Hello, I didnt know where to post this - but I have a bug here :)
I am using latest available UE version from Launcher and I have problem with loading scenes. When I load the scene, for example from game to main menu or vice versa, sometimes I get fatal error crash. (About 1 crash in every 3-4 loadings)
Is there any fixes for that?, also hapens sometimes when minimizing or alttabing
This is actually very important for me <@&213101288538374145> because I have a released game with few thousands of players playing this right now and I cant fix this, would be nice if experts from Epic would check this 🙂 (Exception code 0x00004000)

Hey everyone I'm wanting to do something seemingly simple within Unreal but I cant seem to find the right tutorials or wording while searching for the answer. I want the ability to have a BP actor in the scene that once you interact with it (key press or trigger) it pulls up an image full screen I'm assuming in Ui space? Then I want the ability to have some sort of arrow button than can go forward to the next image or backwards and also the ability to exit out of the images. I think the proper way to set it up is to tie it to a BP actor that I can duplicate and change source images and place around the game world. Does anyone know of a direction they can point me in to figure out something like this in UE4?

ashen brook Mar 7, 2020, 6:15 PM

#

this sounds like a simple user widget - look into UMG 🙂

#

or rather, an interactable placed actor that pulls up a widget

#

it's not beginner level friendly, but with some intermediate blueprinting it's no problem

echo cave Mar 7, 2020, 6:17 PM

#

Thats what I thought but everything I have found so far is fairly general. I probably just need to find a good widget tutorial to leverage with what I need. I'm an environment artist and level designer but I can do blueprinting so hopefully I can find a solid solution thanks for the advice! @ashen brook

ashen brook Mar 7, 2020, 6:19 PM

#

good luck 🙂 Look into blueprint communication if you're not familiar with it yet - that'll be crucial and it's something that for many people is a first hurdle when learning to think like a programmer

I have a custom game mode that derives from BaseGameMode and I have set Default Pawn Class to my custom Pawn (and have specified the model). What have I missed?

Unity was no match for Unreal in this instance, I was able to achieve everything so much faster here!

Unreal is much recommended for new devs.

The lighting that's just set-up out of the box is perfect

wanton mauve Mar 7, 2020, 7:15 PM

#

I assume there is no oob anaglyph option? Failing such a thing, I presume I'll need 2 cameras, rendered to surface, tinted and post-processed into one image (not that I know exactly how to achieve such a thing!)

normal burrow Mar 7, 2020, 7:17 PM

#

If you don't get an answer here on that simon may want to try #graphics it sounds like something they may have an idea of. I personally haven't used render textures yet and dunno if thats even the thing to suggest for this case

Does anyone have an example of using texture-based importance sampling blueprint nodes? I've been looking for an example but I can't find any, the closest I've gotten was this: https://forums.unrealengine.com/development-discussion/blueprint-visual-scripting/1377905-texture-based-importance-sampling-blueprint-nodes-how-to-use

Unreal Engine Forums

I have UV mapped mesh (plane) and I have a grayscale (RGB) texture that fits right over the mesh. I'd like to sample the textures and place static mesh cubes

I want to be able to find a location on a texture with an alpha channel, but I'm having a hard time figuring it out

it will export as png if you export the landscape heightmap

just right-click the heightmap layer and take export to file

when you right click and select export there is not the default tga option

Hey all, anyone here have experience with capture cards?

I'm finishing up a pack for Marketplace submission, and I need to take some nice 60fps 1080p screen capture videos. A lot of the capture cards out there seem to be mostly for streaming HDMI inputs from consoles these days, so I'm wondering if anyone can recommend one that definitely has native PC drivers and can capture natively on the PC it runs on.

A few hours ago I've asked about meshes merging problem, when the newly generated mesh had no mesh collisions on it.
Turned out, that one simply have to assign PhysicsAsset manually to the new mesh. FSkeletalMeshMerge simply doesn't take PhysicsAsset into account, so one have to do it separately.

okay, not the mesh itself, but the skeletal mesh component.. I can't figure out why it get's reset, but it all works after reassigning.

now it won't change! No matter what value I put into the SetPlayrate call it stays slow

so of course I thought, ok, it must be not actually be compiling or the build must not be making it to the player

so I added some logging

the logging is there, as expected, and changes when I change it and recomile

but still, the timeline won't change speeds

rotate the camera in the bp i mean

oh for third person you prob have the rotation controlled by controller

if you really need to you could switch around the input settings in the bp, switching InputAxis MoveForward with InputAxis MoveRight

Yea that was it, for some reason the inputs where different

#

also I have these problems, when i move my mouse the camera doesn't move(I want to make it as in the games but it doesn't work) I need to move the camera when I click on right button of the mouse and move

is there a way to do it by default?

grave osprey Mar 8, 2020, 7:36 AM

i am looking for help.

#

The character (bp char capsule) when given input move. It wobble to left. Then it walk normally. (I use norm blendspace. With onterpolation 0.2) i am sure as hell it work correctly when interpolation set to 0.

#

the problem work when character start moving.

try setting it to 1

is there some kind of hidden default skylight in the editor settings or something?

how to check interpolation curve in animation blend space ?

or does it exist ?

it should be in the details panel

either that, or you manipulate the float value that drives the blendspace

Hey guys

#

Our client apparently wants our unreal project to run smoothly on laptops with integrated graphics

#

after butchering every particle system, deleting all lighting and using a single directional light, tried to force custom lod3 always by setting screen space size to 10k+ for every lod on most props, and fiddling around with the rendering settings

#

it's still very choppy

#

anything else i can try

#

My laptop has azerty keyboard and even when i plug in my qwerty it doesnt want to open console so i can't profile <_<

GetCapsuleComponent()->OnBeginCursorOver.AddDynamic(this, &ACreature::BeginCursorOver);

Would delegates such as this go in the constructor or beginplay?

flat idol Mar 8, 2020, 10:16 AM

#

beginplay

#

@dire zealot add english keyboard input for your os, and switch to english, it should allow the tilde to function. If not, then add new console key in editor settings.

#

in game you can usually press f2 key, that will disable all postprocess and many advanced rendering stuff. if game runs better, then you're frame bound, if game still stutering, then it may be cpu bound.

Can I delete the folder and then reroute it from the editor settings?? Is it safe to do that?

somber quail Mar 8, 2020, 2:35 PM

If you delete the folder then you will need to recompile all shaders and it will just fill up again

There are ways to move it. Look in editor settings for "Derived Data Cache," you can specify a path there

@tame delta There is a vehicle actor in the engine already that has wheel components, you can look into how that is done. Otherwise yes an actor component would be how you can attach an actor to another actor

Only ingame. In Editor all is smooth and fine.

grim ore Mar 8, 2020, 3:30 PM

@tame delta yep my only suggestion is to check out the current wheeled vehicle system

#

@plush yew the first thing to check is if its the level or your project, make a new level (the one with just the platform is fine) and go in game and see if its low res as well

#

@plush yew probably not in this discord, #lounge maybe as its off topic otherwise the support forums for the product itself

at this point it might be one of your config files got changed some how, unless your game mode is doing it (as that would be the same in a new map). made any changes in your game mode?

#

if not you can rename your config folder temporarily in the project so it will use default configs and see what happens when you relaunch the project

my guess is at some point you had something going on, maybe some shader compiles or imports, and the engine noticed it was running slow so it changed the options down automatically and you didnt notice

normal burrow Mar 8, 2020, 4:44 PM

#

So if you have the target transform and the actual transform

#

The applied transform would be the relative from bad to good

lime gull Mar 8, 2020, 4:45 PM

#

How would I get a specific component from an actor for an overlap check?

normal burrow Mar 8, 2020, 4:45 PM

#

You either set the transform of the weapon or apply the delta

lime gull Mar 8, 2020, 4:49 PM

Im trying to say like, if this overlaps this, set this variable
But I need to do that with 4 different components and 4 different variables, will it still work?

rich reef Mar 8, 2020, 4:49 PM

#

I just had to take a moment to think lol

The thing is, I want the pivot point to be where the butt is, but the origin (or whatever its called in UE4) of the skeletal mesh is in the middle of the gun

#

So I cant just rotate the weapon around its own origin

#

Which is why I were thinking about IK (tho thats not really the intent of IK)

#

@normal burrow

lime gull Mar 8, 2020, 4:51 PM

uh so how do I single out the 4 components I need?

abstract relic Mar 8, 2020, 4:52 PM

#

A Boolean with lots of And

rich reef Mar 8, 2020, 4:53 PM

#

@lime gull Wait didnt you just want to get overlap of a specific component? Idk what the others are talking about but you can just select the component in the components list and add a begin overlap event lol

#

Sorry if I didnt understand you right or something

lime gull Mar 8, 2020, 4:54 PM

#

What im trying to do is get the components of a different avtor

#

actor*

rich reef Mar 8, 2020, 4:55 PM

#

So when overlap begins, you want a code to run within a different blueprint, right?

lime gull Mar 8, 2020, 4:55 PM

#

I believe so?
When my player overlaps with something, I want to check if its 4 specific components from a different actor

rich reef Mar 8, 2020, 4:56 PM

#

Well like Im not sure I get it, but if you go into the actor that you want the code to run in, and add a custom event, you can then cast to that character from within the actor with the overlap event, and call that custom event from there

#

Then the code within the "other" actor (The one that isnt being overlapped), will get a execution where you can run your desired code

lime gull Mar 8, 2020, 4:57 PM

#

Here I took a screenshot to try and better explain it

#

I wanna get 4 components from the "BattleGrid"

lime gull Mar 8, 2020, 5:01 PM

#

Oh I think I got it daniel

rich reef Mar 8, 2020, 5:01 PM

#

Ah yes, first you need a object wildcard for the Cast to node.

It basically tells the blueprint type (Like if its controlled by a player character for instance, you would put a "get player character" node for it.
Then you can just drag out from "As Battlegrid" and search for the components you need

#

lime gull Mar 8, 2020, 5:02 PM

#

I took the Other Comp and hit = and then just went from As battle grid and type out the components I needed

rich reef Mar 8, 2020, 5:03 PM

#

Right, if Battlegrid is the component you want to call the on overlap, that is indeed correct

how could I make it so that it destroys the one spawned after 5 seconds.

kindred viper Mar 8, 2020, 6:46 PM

#

@fiery mortar you can retarget the animations onto another skeleton with another mesh. That is done in engine. And making animation for Unreal in Blender is a bit of a tricky subject without getting into how the rig bones are rotated differently and needs a kind of middle man. But there is MrMannequin Tools for Blender that makes that a little easier (although its still tricky if you dont follow it by the letter).

#

Give it a few months though, and the new Unreal Blender plugin will get released and we will all praise Epic and Blender and become one #zen

fiery mortar Mar 8, 2020, 6:47 PM

#

well if I didn't misunderstood it is possible the make the animation in ue4 right? @kindred viper

kindred viper Mar 8, 2020, 6:48 PM

#

yeah there is enough animation tools to do it in Unreal, but its not the perfect method

fiery mortar Mar 8, 2020, 6:48 PM

#

I mean I am happy with the current default animations for player just want to add more so if that's possible I am okay with that

kindred viper Mar 8, 2020, 6:48 PM

#

you can interp between poses in a PoseAsset or various other timeline based stuff.

fiery mortar Mar 8, 2020, 6:48 PM

#

oh really, what would you consider the perfect method

kindred viper Mar 8, 2020, 6:48 PM

#

Externally, and brought in with FBX

#

or not FBX specifically, but yeah as that is standard right now

#

gitf seems to be a bit slow on the uptake even though its supported iirc

fiery mortar Mar 8, 2020, 6:49 PM

#

brought in with fbx from blender? 😄

kindred viper Mar 8, 2020, 6:50 PM

#

Well I would use Blender because I dont sub to Autodesk anymore, although I understand I am making it more difficult for myself by not using Maya or 3dsm. They are technically easier to port animations around to Unreal. Although I highly recommend learning how to use Blender to do it, and how to use Rigify, as that will be the method to do it in the near future

@kindred viper okay man thank you so much

you can do it how you'd like to of course, but components normally don't take on such tasks

tame delta Mar 8, 2020, 8:06 PM

#

I got you, but the childactorcomponent is meant to spawn a childactor right?

#

Oh am I supposed to use the CAC as bare as possible, and literally just spawn an actor

#

so put all my wheel logic into an actual actor?

normal burrow Mar 8, 2020, 8:07 PM

#

its up to you but yes childactor component takes on that functionality, i'm saying shoving additional functionality into it for wheels might not be the best approach

#

yeah

#

a wheeled vehicle actor would probably be a nicer more managable approach

tame delta Mar 8, 2020, 8:07 PM

#

Oh alright, that's why it wasn't exposed in the "main" list of actors to inherit haha

quaint osprey Mar 8, 2020, 8:07 PM

#

@normal burrow is it normal that it didn't import anything else than the instance and the normal maps?

tame delta Mar 8, 2020, 8:08 PM

#

That's what I'm using right now, but I wanted to have my wheels be their own actors

#

Couldn't really think of a better way to do that

normal burrow Mar 8, 2020, 8:08 PM

#

that was gonna be my next question cafe: why have wheels be actors?

#

actor parenting in general is usually avoidable

tame delta Mar 8, 2020, 8:09 PM

#

Otherwise the vehicle has to know where the wheels are...etc, as opposed to just placing wheel actors

normal burrow Mar 8, 2020, 8:09 PM

#

but if its a big part of your game to have them detach then yeah that makes sense

#

Yeah you shouldn't avoid teh actor knowing of its component in the same way you should avoid using slow generic things like find component

#

i asked about unity because it teaches you how to do this wrongly by always needing to find component because there is no central concept of what anything is

tame delta Mar 8, 2020, 8:10 PM

#

Hmm I feel you, but means two things: My vehicle has to handle cases with more or less wheels, or in odd positions (reliant robin) and also placing them on the actor gets weird. I can place SMAs and use a naming scheme to find where they were placed within the actor, or tag SMAs, but it all feels a bit abstract

normal burrow Mar 8, 2020, 8:10 PM

#

Beriadan check the parent material of the instance, this is likely the material material, if not the parent of that

#

your right cafe

#

but good news is

#

you can handle wheel count and everything in the actor

#

and probably should

tame delta Mar 8, 2020, 8:11 PM

#

In theory the physics is all self contained for a wheel. It has a suspension, it handles frictions...etc and just applies forces to the parent body. All the wheel has to know is that it's a wheel, that it can/can't turn, drive, brake...etc

normal burrow Mar 8, 2020, 8:12 PM

#

I can assure you the count of components on something is a messy way to do things where you'll likely be frequently ask the engine do do a lot more finding for you

tame delta Mar 8, 2020, 8:12 PM

#

The parent (the car body itself) is just a dumb block of mass, and perhaps routes input to them

normal burrow Mar 8, 2020, 8:12 PM

#

Yea Cafe

tame delta Mar 8, 2020, 8:12 PM

#

Well realistically any actor only has to search the tree on beginplay and hold references to them (which is what I'm doing)

normal burrow Mar 8, 2020, 8:13 PM

#

What i'd really recommend is that you understand how construction scripts and child classes work

tame delta Mar 8, 2020, 8:13 PM

#

I realize now that childactorcomponents are just dummy components meant to spawn an actor and attach it. I thought the actual childactor is spawns was part of it, that was my mistake 🙂

normal burrow Mar 8, 2020, 8:13 PM

#

Blueprints for example exist to do as little as change the skin, to as much as declare more wheels

#

so you can have a very verbose way of defining wheels in the consturction script or OnConstruction in data that is defined in the blueprint that is accessible by the c++

#

such as a struct containing the positions of each wheel and their orientation

#

where OnConstruct in c++ reads this list of structs and makes the components

tame delta Mar 8, 2020, 8:14 PM

#

Yeah but this makes it kind of hard to iterate and line up wheels with the model 😕

normal burrow Mar 8, 2020, 8:14 PM

#

so when your game starts it doesn't run the logic

#

how does it make it difficult?

tame delta Mar 8, 2020, 8:16 PM

#

Well optimally I'd like to open my actor, place my wheels as I want, tick a few checkboxes on them to say whether they are powered/turning/braking...etc

#

Moving, adding or deleting wheels would be very easy 🤷‍♀️

normal burrow Mar 8, 2020, 8:17 PM

#

so imagine you had a struct { FTransform Where; EBitFlagsOfWhat Can; }

#

and an array of these

#

then your construction just makes these things from that struct, and has a separate array of the instanced components

tame delta Mar 8, 2020, 8:18 PM

#

But this means I need to guess my wheel transform, radius and all no?

#

I don't have a visual feedback or a way to use the actor/level editor (or whatever else) to tune all that

normal burrow Mar 8, 2020, 8:18 PM

#

i think the confusing part might be that your thinking when you change this array in the details panel you wont see a difference in teh viewport preview

construction script/construction runs with every manual change to a property

tame delta Mar 8, 2020, 8:19 PM

tame delta Mar 8, 2020, 8:21 PM

#

@normal burrow Yeah of course 🙂 I'm just trying to find the best way, so that later on I don't have to change the architecture because of poor foresight

#

Essentially right now I have a CarActorComponent that I slap on an actor and it handles all physics

quaint osprey Mar 8, 2020, 8:21 PM

#

📎 Screenshot_176.png

tame delta Mar 8, 2020, 8:22 PM

#

The main two ways that I saw were to add SMAs for wheel and have that actor (on construction or beginplay) read the root children and look for those wheels. Wheels could have a naming scheme or tags (probably tags tbf)

#

I thought about using childactorcomponents instead in order to set the logic on the wheels directly (and not just have them be SMAs) but this might not be the best option 🤷‍♂️

#

~~SMA~~ SMCs

#

Something a bit like that https://puu.sh/FittB/d861d2e382.png

normal burrow Mar 8, 2020, 8:24 PM

#

First: seems like your really avoiding embracing the car as an actor

tame delta Mar 8, 2020, 8:24 PM

#

Obvious issue is that tags are just flags, so if I want to change radius and all it's not really an option

normal burrow Mar 8, 2020, 8:24 PM

#

actorcomponents are fine for what your doing though

#

but the actor itself may end up having little significance which is likely something you'd want to avoid

tame delta Mar 8, 2020, 8:25 PM

#

That's just so that I can have multiple actor version of it (I think)

#

but yeah I saw the actor as just a glorified container

normal burrow Mar 8, 2020, 8:25 PM

#

But now if you want to know if somethings a vehicle

#

you have to see if that component exists

#

vs just checking if its a vehicle actor

#

anyways though, you could have a blueprintimplementableevent DescribeWheels where the implementor (blueprint) just lists all the wheels it has and their capabilities

#

that would be another way of doing it

#

then you just call describewheels in OnConstruction so that the lookup isn't done at spawn

tame delta Mar 8, 2020, 8:27 PM

#

Yeah but that still doesn't solve how I define my wheels 😛

normal burrow Mar 8, 2020, 8:27 PM

#

it does though

#

you just place them

#

then override the blueprint function

tame delta Mar 8, 2020, 8:27 PM

#

So what are the wheels then?

normal burrow Mar 8, 2020, 8:27 PM

#

they are the static mesh components

tame delta Mar 8, 2020, 8:28 PM

#

Honestly I feel like that DescribeWheels method would do the same as method directly in the actor/actorcomponent no?

#

If I wanted to have a similar setup, but have booleans in my wheel SMCs, how you would you go about it?

normal burrow Mar 8, 2020, 8:28 PM

#

what i'm saying is

#

you have
TArray<USceneComponent*>Wheels; on ACar

#

then in blueprints for your car you override DescribeWheels to populate said array

#

you could use more than just that for the data in the array

#

but now you can put any number of wheels on the vehicle so long as you properly report them in the describe function

tame delta Mar 8, 2020, 8:30 PM

#

Okay I see

normal burrow Mar 8, 2020, 8:30 PM

#

you could certainly make a UStaticMeshComponent child type for wheels

tame delta Mar 8, 2020, 8:30 PM

#

So yeah realistically I should have Car be an actor, I can do that. then I just inherit that actor for as many blueprints as I want version of this car right?

normal burrow Mar 8, 2020, 8:30 PM

#

Unlike the child actor component, primitive types do handle a lot already so its not unheard of if your willing to limit your wheels to static mesh components

#

right

tame delta Mar 8, 2020, 8:31 PM

#

Okay I was just afraid making a C++ car actor meant that this was it, and I couldn't really get multiple version of it BP style

not conveniently anyway

normal burrow Mar 8, 2020, 8:32 PM

#

actors are super convenient

#

it took me awhile to learn the ropes too

tame delta Mar 8, 2020, 8:32 PM

#

🙂

#

So if I extend an SMC to get add all the data I want directly in it, how will I be able to give it a static mesh?

#

Oh I guess it's gonna be like any other SMC right, just drag and drop a staticmesh to the details pane...etc

normal burrow Mar 8, 2020, 8:34 PM

#

what you do with the car component there, is something i'd do for things like coconuts or otherwise gnawable items. so i don't have to rewrite the things a dolphin can carry in its mouth over and over through an interface, but i do still use an interface on the actor to expose the component rather than naively looking for its existance for example

#

right Cafe

#

in your native description, you can define there if its a drive wheel or a brake wheel etc

tame delta Mar 8, 2020, 8:36 PM

#

Gotcha, I'll do that then, thanks 🙂

@elder agate do you have visual studio?

elder agate Mar 8, 2020, 8:40 PM

#

vs code

#

@normal burrow

normal burrow Mar 8, 2020, 8:40 PM

#

does this let you debug?

elder agate Mar 8, 2020, 8:40 PM

#

it would, but this crash is occuring before i can open the game or play it

normal burrow Mar 8, 2020, 8:41 PM

#

you can't start the game with the debugger like vs would?

elder agate Mar 8, 2020, 8:41 PM

#

The project crashes the editor when i try to open it

#

as in I cant get to the game at all, opening the project crashes the project

normal burrow Mar 8, 2020, 8:41 PM

#

in visual studio you would launch the project with F5 where the crash at startup would be caught by the debugger

#

dunno if thats the case for vs code

elder agate Mar 8, 2020, 8:42 PM

#

i mean, unreals crash reporter is giving me Assertion failed: Export.Object == nullptr [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/CoreUObject/Private/UObject/LinkerLoad.cpp] [Line: 4317]

normal burrow Mar 8, 2020, 8:42 PM

#

Dank, I understand

#

again, visual studio catches these things

abstract relic Mar 8, 2020, 8:43 PM

#

Answer is no. They’re not using the debugger

#

Use the debugger

elder agate Mar 8, 2020, 8:43 PM

#

I just tried debugging the script on vs code, it stops at the same error, and prints this before it: [2020.03.08-20.42.59:091][ 0]LogUObjectGlobals: Warning: Failed to find object 'Actor None./Game/Blueprints/FPSCharacter' [2020.03.08-20.42.59:096][ 0]LogUObjectGlobals: Warning: Failed to find object 'Actor None./Game/Blueprints/FPSCharacter'

normal burrow Mar 8, 2020, 8:44 PM

#

perfect

#

now can you view the call stack in vscode?

#

while it is stopped

elder agate Mar 8, 2020, 8:44 PM

#

let me check

#

callstack is in this screencap on the left to the bottom

📎 unknown.png

#

MainThrd Paused on breakpoint

normal burrow Mar 8, 2020, 8:46 PM

#

very unfamiliar with vscode but does that arrow on the left of mainthrd expand it?

#

these are threads on the left side under callstack but not seeing a callstack

elder agate Mar 8, 2020, 8:46 PM

#

📎 unknown.png

#

is this better?

normal burrow Mar 8, 2020, 8:47 PM

#

yep

midnight bolt Mar 8, 2020, 8:47 PM

#

how can i search in content browser more than one name? like i want to find palm1 and palm2 static mesh, but if i type both none are found

normal burrow Mar 8, 2020, 8:47 PM

#

if you look through it, are there not any calls to your game module in there?

elder agate Mar 8, 2020, 8:47 PM

#

📎 unknown.png

#

no, but there is a call to the flamethrower and i think thats where the issue was

normal burrow Mar 8, 2020, 8:48 PM

#

there is your cause yeah

#

and this is how you find stuff in the future

elder agate Mar 8, 2020, 8:48 PM

#

since I mistakenly used BeginPlay() instead of Play() for an audio component

#

only question is, how can i fix it? I already changed the flame script to do Play instead but the editor wont recognize the change

#

actually, thats incorrect

#

or maybe it isnt, the line 46 its referring to is when i try to find the FPSPlayer

normal burrow Mar 8, 2020, 8:49 PM

#

no its 46 of the header

#

not the cpp

elder agate Mar 8, 2020, 8:50 PM

#

which according to this is:

📎 unknown.png

normal burrow Mar 8, 2020, 8:50 PM

#

yeah dank you can't do that

#

You need to add a constructor to do that kind stuff basically and there are specific ways of doing it there

#

idea is to initialize it to some file in your proejct right?

elder agate Mar 8, 2020, 8:51 PM

#

yeah, i think I already have something for that

#

right now im more interested in getting the editor open, let me make that line point to nullptr and see if it runs

normal burrow Mar 8, 2020, 8:52 PM

#

yeah taht would solve it

elder agate Mar 8, 2020, 8:52 PM

#

let me check real quick

#

nope, still crashes

#

let me get back into the debugger

normal burrow Mar 8, 2020, 8:53 PM

#

get into a habit of starting with the debugger 😄

#

type just palm @midnight bolt

midnight bolt Mar 8, 2020, 8:54 PM

#

well the final point is that i want to filter through several names, so like palm grass tree

#

how do i get all 3 to display?

normal burrow Mar 8, 2020, 8:55 PM

#

anything with palm in the name will show up

elder agate Mar 8, 2020, 8:55 PM

#

so @normal burrow its still pointing to the line, which is now AActor* ActorToIgnore = nullptr;

normal burrow Mar 8, 2020, 8:55 PM

#

then it did not compile

elder agate Mar 8, 2020, 8:55 PM

#

what can i do to get it to compile without going through the editor?

normal burrow Mar 8, 2020, 8:55 PM

#

oof lol

#

ponkkis?

#

I don't know anything about vsc, ponkkis might know

#

visual studio just compiles the code when you launch the thing

elder agate Mar 8, 2020, 8:56 PM

#

let me try the build and run debug one more time

normal burrow Mar 8, 2020, 8:57 PM

#

make sure you've saved the header

elder agate Mar 8, 2020, 8:57 PM

#

i did

normal burrow Mar 8, 2020, 8:58 PM

#

may want to grab visual studio 19 tbh dank

#

believe you can have both installed right?
