(39) 's Extra Blueprint Nodes for You as a Plugin, No C++ Required!

[AbleChen]

@RenaCava

So I’m working with the Get Sound Wave from File node in 4.24, it creates the USoundWave with the correct duration but no actual audio samples, so there’s no sound playing. Same thing happens with the other two nodes (at location and attached). Importing the .ogg file manually, it plays in editor, though somewhat defeats the point of the nodes. Any ideas?

Hello, I encountered the same problem. Do you have any solutions?

[Nobody]

Yeah Sound Importing is broken for me in 4.25 aswell. Tried modifing the code a bit but as I am not very good in c++ so the only thing I could manage is to get some static noise after a week on working on it.

Here’s working modified version of that function, add it to your blueprint function library. Check if it works in packaged game.

USoundWave* GetSoundWaveFromFile(const FString& FilePath)
{

#if PLATFORM_PS4
UE_LOG(LogTemp, Error, TEXT("UVictoryBPFunctionLibrary::GetSoundWaveFromFile ~ vorbis-method not supported on PS4. See UVictoryBPFunctionLibrary::fillSoundWaveInfo"));
return nullptr;
#else
USoundWave* sw = NewObject<USoundWave>(USoundWave::StaticClass());

if (!sw)
return NULL;

//* If true the song was successfully loaded
bool loaded = false;

//* loaded song file (binary, encoded)
TArray < uint8 > rawFile;

loaded = FFileHelper::LoadFileToArray(rawFile, FilePath.GetCharArray().GetData());

if (loaded)
{
FByteBulkData* bulkData = &sw->CompressedFormatData.GetFormat(TEXT("OGG"));

bulkData->Lock(LOCK_READ_WRITE);
FMemory::Memcpy(bulkData->Realloc(rawFile.Num()), rawFile.GetData(), rawFile.Num());
bulkData->Unlock();

//loaded = fillSoundWaveInfo(sw, &rawFile) == 0 ? true : false;
FSoundQualityInfo info;
FVorbisAudioInfo vorbis_obj;
if (!vorbis_obj.ReadCompressedInfo(rawFile.GetData(), rawFile.Num(), &info))
{
//Debug("Can't load header");
loaded = false;
}

if (!sw) loaded = false;
sw->SoundGroup = ESoundGroup::SOUNDGROUP_Default;
sw->NumChannels = info.NumChannels;
sw->Duration = info.Duration;
sw->RawPCMDataSize = info.SampleDataSize;
sw->SetSampleRate(info.SampleRate);

**sw->RawPCMData = (uint8*)FMemory::Malloc(sw->RawPCMDataSize);
vorbis_obj.ExpandFile(sw->RawPCMData, &info);**

loaded = true;
}

if (!loaded)
return NULL;

return sw;
#endif
}

Boldened code is what’s different from the original.

Thanks a lot! I can confirm works now in 4.25 editor and packaged/shipping build!

Hey fine people of the forums!

I use the .wav file loading code to …well, load .wav files. Works great. I use a UAudioComponent with the resulting USoundWave like so:

AudioComp->SetSound(Sound);
AudioComp->Play(0);

That works like a charm. EXCEPT when I give the Play function a StartTime like so

AudioComp->Play(1.0f);

Now nothing plays anymore. I’ve tried to chase down the rabbit hole of the Unreal engine code to see what is need for the StartTime to work, but I couln’t figure it out. Any help/suggestions are greatly appreciated.

EDIT:

I found my mistake, pretty dumb but I’m leaving it here for completeness:

I did :

USoundWave* Sound;
Sound->RawData.Lock(LOCK_READ_WRITE);
void* LockedData = Sound->RawData.Realloc(RawData.Num());
FMemory::Memcpy(LockedData, WaveInfo.SampleDataStart, WaveInfo.SampleDataSize);
Sound->RawData.Unlock();

instead of :

USoundWave* Sound;
Sound->RawData.Lock(LOCK_READ_WRITE);
void* LockedData = Sound->RawData.Realloc(RawData.Num());
FMemory::Memcpy(LockedData, RawData.GetData(), WaveInfo.SampleDataSize);
Sound->RawData.Unlock();

and since ‘WaveInfo.SampleDataStart’ is null, the RawData in the Sound wave was also then a null pointer. Since the Unreal sound processing on relies on the Sound->RawData, meant Unreal could not do its thing.
So, totally my stupidity.

Thanks anyway, cheers.

Hello everyone!

First of :
@thank you for sharing awesome asset for us!

I am using your LoadObjectFromAssetPath BP node, in the editor to load assets into my scene.

I am struggling to get it to load stuff runtime, from a folder that has not been packaged with the game…(Content creator’s folder for importing clothes as skeletalmeshes and props as staticmeshes)
Not sure what kind of path can I feed to the node that works with runtime, non-packaged stuff.

Maybe there is another node that I do not know of?

Many thanks

Hello everyone does anyone happen to seen my post?

[Joaobrasil65]

Hope that the Scene Capture Project functions & CreateTextureRenderTarget2D function are of use to someone.

We’ve been using CreateTextureRenderTarget2D() for our optical sights and UI related elements for quite some . It allows us to create texture render targets on the fly and not have to worry about creating them manually in the content browser.

We use Project() for rendering attachment points for our character and items in the customisation UI.

I created a crappy quick mini-map project that uses it as an example.
I’ll see about getting it online soon.

.

Do you have any examples of how to implement for a scope in a dedicated server multiplayer game?

[Kris]

It is not something that would be on a dedicated server - it would be on the clients.
There are already a number of tutorials/examples floating around showing how to use a scene capture component to render to textures.
A 3d optic is no different to .

I couldn’t figure out how to install … First off I had a hard finding the vertex snapper since I thought that VictoryPlugin25 didn’t have the instanced mesh thing for static meshes (didn’t find it) then when I try to start up the project with the version of the plugin that has “VictoryEdEngine” which I supposedly need for the static mesh stuff (only thing I need from the plugin) it just gives a bunch of errors when I try to compile…

So…
Does the 4.25 version of the plugin have the ‘combine multiple static meshes into an instanced static mesh’ stuff? If so, how can I get it to work? I just couldn’t figure it out, also I’m tired so that may be a factor in why I couldn’t figure out

Hi there,

I would like to get the save string array to work frame by frame. So that for example i would directly print multiple position metadata of agents per frame into a file.

Hey there,
I wanted to let you know, @, that when compiling a game in 4.25, I get some “warnings” for future versions related to your awesome plugin:

Hey ,

Saw that in 4.25 several of the Get Pixel/s from T2D nodes are now deprecated and you recommend voicing any continued need for them in thread. I’m one of the people who uses those nodes and they’ve been a critical component of my current project. Not having access to to them is preventing me from moving to 4.25 until a solution is found. I would not have initially said was an urgent need, but as new issues/lack of a in the version I use (4.22) rub up against the needs of the project, I’m finding that upgrading is but a necessity so having these nodes available has become a far more urgent matter.

I hope it’s possible to find a solution and thank you so much for plugin. It’s enabled me to do things previously out of reach.

@Thanks for the plugin!! it’s fantastic.
I just converted a project from 4.24 to 4.25 and replaced the victory plugin with the 4.25 version, works fine, but a function called “Vicrotry Get Pixel from T2D” is listed as deprecated and doesn’t work. The blueprint note said to post something here if it’s needed urgently, and it very much is.
If there anything you can do about ?

Thanks!

@ why i can see the Line of node “draw Thick 3Dline” when shipping packages. (development package and standalone can see). i use UE4.19

[kevin791129]

Hi,

I’ve been trying to find a way to sample pixels from Texture2D in 4.25 but I get compiler error C2440: ‘static_cast’: cannot convert from ‘const ElementType *’ to ‘const FColor *’.
After some searching, I came across post Static_cast error - C++ - Epic Developer Community Forums.
The solution is to change static_cast to reinterpret_cast.
Confirmed working for my Windows shipping build.

@kevin791129 unfortunately didn’t fix the Victory_GetPixelsArrayFromT2D node on my end, I’m still getting an empty array when I change the cast.

When i package with the custom engine for HTML 4.24, and have builded your plugin into the project, it shows a error message when im using the node “Victory HTML5 set cursor visible”

The error happends when i try to start the game in a web browser, and it says “Uncaught RuntimeError: function signature mismatch”

ONLY happends when i connect the node to execute. When ever that victory node is removed, the package runs fine in the webbrowser.

@I’m trying to compile your plugin but it says there is an error:

Error C2664 'bool IImageWrapper::GetRaw(const ERGBFormat,int32,TArray<uint8,FDefaultAllocator> &)': cannot convert argument 3 from 'const TArray<uint8,FDefaultAllocator> *' to 'TArray<uint8,FDefaultAllocator64> &'

code where the error shows is here:

const TArray<uint8>* UncompressedBGRA = NULL;
if (ImageWrapper->GetRaw(ERGBFormat::BGRA, 8, UncompressedBGRA))

the function is Victory_LoadTextureFromFile

Hey @ @frostic Was there any solution to ?
