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

[Nsomnia]

Dear Community,

I've upgraded my Victory BP plugin to 4.9! (And TK-Master did too!)

Unfortunately in 4.9.0 there's a bug involved with editor plugins that I believe has to be fixed engine-side as it is affecting the new 4.9 plugin templates as well.

So this version of my plugin does not include the Vertex Snap Editor.

To avoid a crash on editor startup, please remember to remove these lines from your config file if you were using the vertex snap editor:

this

[/Script/Engine.Engine]
UnrealEdEngine=/Script/VictoryEdEngine.VictoryEdEngine

becomes this

;[/Script/Engine.Engine]
;UnrealEdEngine=/Script/VictoryEdEngine.VictoryEdEngine

Much happiness glows around me Java this semester, c++ next. And then the Unreal API for all its hugeness and oddness.

Seems the IsValidIndex node doesn't like 4.9.
I'll get the fix to Rama shortly

Victory Ed Engine Plugin, Separate Plugin and Download Now

Dear Community,

As of 4.9.0, My Vertex Snap Editor Plugin is now a separate plugin, called VictoryEdEngine!

Download Link (145kb)
https://wiki.unrealengine.com/File:VictoryEdEngine.zip

This is a plugin that does not package with your game as it is only designed to modify Unreal Engine 4 to add support for vertex snapping while in the Level Editor Viewport.

Enjoy!

Hey Rama!

Why Not Include All Variants?

The reason I can't include all variants is because of a wiki file size limitation of 20mb

Why not just upload the plugin here in the forums or just link in the wiki to a separate download location (like google drive)?

Another question: Could you somehow integrate this into your plugin?

https://forums.unrealengine.com/show...or-Win-and-Mac

Epic seems to be quite slow with integrating custom hardware cursors into the engine, they don't say anything about it, no idea whether it will happen within the next 1 or 2 years So there is the code which just needs to get added to the source for making custom cursors work, but of course doing this manually after each new version and each hotfix and compile the engine is just a drawback regarding usability. But so many games need custom cursors! The default windows hand cursor is not really fitting for most games, and software cursors feel laggy, even at 60 fps.

Could you integrate the code mentioned in the thread above into your plugin and make it work as a BP node or would it not work inside of a plugin?

Thanks!

Could you post a fix here? I'm currently stuck on this.

IsValidIndex fix:

    DECLARE_FUNCTION(execArray_IsValidIndex)
    {
        Stack.MostRecentProperty = nullptr;
        Stack.StepCompiledIn<UArrayProperty>(NULL);
        void* ArrayAddr = Stack.MostRecentPropertyAddress;
        UArrayProperty* ArrayProperty = Cast<UArrayProperty>(Stack.MostRecentProperty);
        if (!ArrayProperty)
        {
            Stack.bArrayContextFailed = true;
            return;
        }
        P_GET_PROPERTY(UIntProperty, Index);
        P_FINISH;

        bool WasValid = GenericArray_IsValidIndex(ArrayAddr, ArrayProperty, Index);
        *(bool*)RESULT_PARAM = WasValid;
    }

bool UVictoryBPFunctionLibrary::GenericArray_IsValidIndex(void* TargetArray, const UArrayProperty* ArrayProp, int32 Index)
{
    bool bResult = false;

    if (TargetArray)
    {
        FScriptArrayHelper ArrayHelper(ArrayProp, TargetArray);
        bResult = ArrayHelper.IsValidIndex(Index);
    }

    return bResult;
}

Hey Kris, your LoadTexture2D_FromFileByExtension node isn't working correctly for me any more in 4.9, I'm getting a sort of hue shifted effect:



How the colours should look:



edit:
Changing
Texture = UTexture2D::CreateTransient(ImageWrapper->GetWidth(), ImageWrapper->GetHeight(), PF_B8G8R8A8);

to

Texture = UTexture2D::CreateTransient(ImageWrapper->GetWidth(), ImageWrapper->GetHeight(), PF_R8G8B8A8;

fixes it

I have a problem with a linux build. I tried a version of the plugin from June and also a version from 08-26-15. The both had this error. Any ideas?

Thanks for your awesome plugin!

Funny, that's what my version already has.
I must have updated it a while back without sending it to Rama.
My bad

Hi @Rama,

Thanks for the plugin!

I had to make a fix to get it building under Linux - the diff follows.

Have you considered putting your code on Github so people can send you pull requests for fixes/additions that you can easily decide to accept or not? If you are wlling, I offer to help set it up for you.

Now I need to see how to deal with the Dedicated Server build failing because VictoryBPLibrary depends on UElibPNG - the build error:

Building DescentServer...
Using clang version '3.5.0' (string), 3 (major), 5 (minor), 0 (patch)
Linux dedicated server is made to depend on UElibPNG. We want to avoid this, please correct module dependencies.

The CLR exception details may provide more information:  System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> ERROR: Linux dedicated server is made to depend on UElibPNG. We want to avoid this, please correct module dependencies.

Edit: I had to remove ImageWrapper as a dependency and ifdef out all code using it in the plugin to get DedicatedServer to build.

This fixed my problem as well. Thanks Stormwind!

[Shrooblord]

I'm getting an error saying "VictoryPlugin could not be loaded because the module VictoryBPLibrary could not be found." I've looked in the plugin's Source folder and... well... it's right there. Not sure what the plugin is not seeing that I can.

[Rama]

Changing
Texture = UTexture2D::CreateTransient(ImageWrapper->GetWidth(), ImageWrapper->GetHeight(), PF_B8G8R8A8);

to

Texture = UTexture2D::CreateTransient(ImageWrapper->GetWidth(), ImageWrapper->GetHeight(), PF_R8G8B8A8;

fixes it

Dear Mosel3y,

I just checked and the current version of the function has this source code, which includes your fix, nice to hear from you!

This is the most recent Victory Plugin on mediafire and the wiki

UTexture2D* UVictoryBPFunctionLibrary::LoadTexture2D_FromFileByExtension(const FString& ImagePath, bool& IsValid, int32& OutWidth, int32& OutHeight)
{
	UTexture2D* Texture = nullptr;
	IsValid = false;

	// To avoid log spam, make sure it exists before doing anything else.
	if (!FPlatformFileManager::Get().GetPlatformFile().FileExists(*ImagePath))
	{
		return nullptr;
	}

	TArray<uint8> CompressedData;
	if (!FFileHelper::LoadFileToArray(CompressedData, *ImagePath))
	{
		return nullptr;
	}
	
	IImageWrapperPtr ImageWrapper = GetImageWrapperByExtention(ImagePath);

	if (ImageWrapper.IsValid() && ImageWrapper->SetCompressed(CompressedData.GetData(), CompressedData.Num()))
	{ 
		const TArray<uint8>* UncompressedRGBA = nullptr;
		
		if (ImageWrapper->GetRaw(ERGBFormat::RGBA, 8, UncompressedRGBA))
		{
			Texture = UTexture2D::CreateTransient(ImageWrapper->GetWidth(), ImageWrapper->GetHeight(), PF_R8G8B8A8);
			
			if (Texture != nullptr)
			{
				IsValid = true;
				
				OutWidth = ImageWrapper->GetWidth();
				OutHeight = ImageWrapper->GetHeight();

				void* TextureData = Texture->PlatformData->Mips[0].BulkData.Lock(LOCK_READ_WRITE);
				FMemory::Memcpy(TextureData, UncompressedRGBA->GetData(), UncompressedRGBA->Num());
				Texture->PlatformData->Mips[0].BulkData.Unlock();
				Texture->UpdateResource();
			}
		}
	}

	return Texture;
}

You're welcome, and I am glad Stormwind's Linux packaging fix worked for you!

Yes, sorry about that guys, I've just realized I'd coppied in an older version that I had broken myself, not the latest
