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

[Sahkan]

I did actually expose my Victory Core BP Library yes, so you can include it in your build cs!

The fact that I include VICTORYBPLIBRARY_API means that the symbols get exported so that you include my plugin functions and classes and compile code at the project level.

You need to include my plugin module in your build cs as a dependency in order to use #include "VictoryBPLibrary.h"

PublicDependencyModuleNames.AddRange(new string[] { 
	"Core", "CoreUObject", "Engine", "InputCore",
			
	"VictoryPlugin"
});

Rama

Thanks, but when i add "VictoryPlugin" into my OldSchoolNightmare.Build.cs file, and it looks like that:

PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "VictoryPlugin" });

I'm getting these erros:

Error	1	error : Exception thrown while processing dependent modules of OldSchoolNightmare	C:\OldSchoolNightmare\Intermediate\ProjectFiles\EXEC	OldSchoolNightmare
Error	2	error : Couldn't find module rules file for module 'VictoryPlugin'.	C:\OldSchoolNightmare\Intermediate\ProjectFiles\EXEC	OldSchoolNightmare

Ooops, please use this

VictoryBPLibrary

instead of this

VictoryPlugin

Let me know how it goes!

Get All Screen Resolutions

Now works in packaged games!

You can use this with your UMG menus!

It gathers data specific to the end user's display adapter, including all available refresh rates

old but has nice in-game pic


actual!

Dear Rama, I feel as if some of the plugin nodes have names that seem a bit odd, for example: "Options Menu Get Display Adapter Screen Resolutions". I think that a more fitting name could be: "Get Supported Screen Resolutions", or "Get Display Adapter Screen Resolutions", I just feel as if it is a bit harder to understand when the title has unnecessary words, and also harder to search. Just thought I'd post this in case you change the way you name them.

Thanks, now it compiles with the added module, but when i add the header to my cpp file (#include "VictoryBPLibrary.h"), it gives me this error:

Error	1	error C1083: Cannot open include file: 'VictoryBPLibrary.h': No such file or directory	C:\OldSchoolNightmare\Source\OldSchoolNightmare\BYM_Building_Base.cpp	8	1	OldSchoolNightmare

I agree the Options Menu part is unnecessary, but if I change the name now, it will invalidate a lot of people's BP code who are using my plugin.

I will investigate non-destructive ways to rename, perhaps using a meta friendly name.

But you see the issue now, renaming is a process that requires everyone else to adjust to my decision to rename a node.

Slate Build CS Dependencies Required

Also tried : #include "VictoryBPFunctionLibrary.h" and it gave me this:

Error	1	error LNK2019: unresolved external symbol "__declspec(dllimport) public: __cdecl FSlateFontInfo::~FSlateFontInfo(void)" (__imp_??1FSlateFontInfo@@QEAA@XZ) referenced in function "void __cdecl DestructItems<class FSlateDrawElement>(class FSlateDrawElement *,int)" (??$DestructItems@VFSlateDrawElement@@@@YAXPEAVFSlateDrawElement@@H@Z)	C:\OldSchoolNightmare\Intermediate\ProjectFiles\BYM_Building_Base.cpp.obj	OldSchoolNightmare

Dear Sahkan,

The latter is correct:

#include "VictoryBPFunctionLibrary.h"

The problem is that your build cs needs to include the same Slate/UMG modules that I am including in the Victory BP Library plugin.

Refer to the Victory BP Library build cs to see which modules you should add:

 PublicDependencyModuleNames.AddRange(
			new string[] { 
				"Core", 
				"CoreUObject", 
				"Engine", 
				"InputCore",
				
				"RHI",
				"RenderCore",
				 
				"HTTP",
				"UMG", "Slate", "SlateCore",
				
				"ImageWrapper",
				
				"PhysX", "APEX" 
			}
		);

Try adding these to your own public dependencies (project build cs)

"UMG", "Slate", "SlateCore",

That should do it!

Thanks, now it compiles

Load Texture 2D From File!

JPG, PNG, BMP, ICO, EXR, and ICNS are Supported File Formats !



With this node you can load a Texture 2D from a file during runtime!

I output for you the width and height of the loaded image!

Now you can easily create Texture 2D's from image files in Blueprints, during runtime!


Special Note!

Tim Sweeney liked this node!


Enjoy!

Rama

PS: Make sure to include the file extension when you use this node!



~~~

C++ Code For You

Here is the core C++ function involved, entire source is in the download! I wrote my own Enum for the file formats.

UTexture2D* UVictoryBPFunctionLibrary::Victory_LoadTexture2D_FromFile(const FString& FullFilePath,EJoyImageFormats ImageFormat, bool& IsValid,int32& Width, int32& Height)
{
	IsValid = false;
	UTexture2D* LoadedT2D = NULL;
	
	IImageWrapperModule& ImageWrapperModule = FModuleManager::LoadModuleChecked<IImageWrapperModule>(FName("ImageWrapper"));
	
	IImageWrapperPtr ImageWrapper = ImageWrapperModule.CreateImageWrapper(GetJoyImageFormat(ImageFormat));
 
	//Load From File
	TArray<uint8> RawFileData;
	if (!FFileHelper::LoadFileToArray(RawFileData, * FullFilePath)) 
	{
		return NULL;
	}
	
	  
	//Create T2D!
	if (ImageWrapper.IsValid() && ImageWrapper->SetCompressed(RawFileData.GetData(), RawFileData.Num()))
	{ 
		const TArray<uint8>* UncompressedBGRA = NULL;
		if (ImageWrapper->GetRaw(ERGBFormat::BGRA, 8, UncompressedBGRA))
		{
			LoadedT2D = UTexture2D::CreateTransient(ImageWrapper->GetWidth(), ImageWrapper->GetHeight(), PF_B8G8R8A8);
			
			//Valid?
			if (!LoadedT2D) 
			{
				return NULL;
			}
			
			//Out!
			Width = ImageWrapper->GetWidth();
			Height = ImageWrapper->GetHeight();
			 
			//Copy!
			void* TextureData = LoadedT2D->PlatformData->Mips[0].BulkData.Lock(LOCK_READ_WRITE);
			FMemory::Memcpy(TextureData, UncompressedBGRA->GetData(), UncompressedBGRA->Num());
			LoadedT2D->PlatformData->Mips[0].BulkData.Unlock();

			//Update!
			LoadedT2D->UpdateResource();
		}
	}
	 
	// Success!
	IsValid = true;
	return LoadedT2D;
}

Hi Rama, are TMaps replicated?

[J. J. Franzen]

Awesome Rama. Would it be possible to add access to the pixel array via this node as in your other one? Or perhaps a more generalized Texture Reference object to pixel array function?

Fails on Android

I just converted my project to a C++ project. I can build and run the project in Visual Studio. I can build and compile the project in the editor without any issues. I can package to Win64, no problem. But as soon as I try to package to Android and/or launch to Android, it fails.

When it was a BP only project, I was able to build to Android without any issues. The only difference between this project and BP only project, is that I added the Victory BP plugin. Now if I remove the plugin, I can build again.

Here's part of the log that specifies my error. It seems that it's missing something

C:\Users\Marc-Andre\Google Drive\Hangar 74\UE4\Bengal\Intermediate\Build\Android\Bengal\Development/UELinkerFixups.cpp:615: error: undefined reference to 'EmptyLinkFunctionForStaticInitializationSettings()'

Thus it cannot create an so file.

Hi Rama, are TMaps replicated?

No they are not replicated automatically, replication like that would have to be orchestated by you just like for most other gameplay features. My recommendation would be to only run the logic requiring TMaps on the server-side and just pass the output/results/effects to clients via custom replicated events.

Awesome Rama. Would it be possible to add access to the pixel array via this node as in your other one? Or perhaps a more generalized Texture Reference object to pixel array function?

Cheers,

J^2

Texture2D -> Pixel array is a great idea, I will have to look into it when I get the chance!

Android Build Issues

I have many reports of people compiling my plugin for Android successfully, so I am not sure why you in particular are having an issue.

If anyone who is routinely building for Android can provide any additional insight in the matter that would be great!

Do you have any other log info that seems relevant besides what I've copied above?

This error does not give me a whole lot to work with.

Here's the first key line:

creating C:/Users/Marc-Andre/Google Drive/Hangar 74/UE4/Bengal/Plugins/VictoryPlugin/Binaries/Android/VictoryBPLibrary-Static-armv7-es2.a 

_

and then this:

C:\Users\Marc-Andre\Google Drive\Hangar 74\UE4\Bengal\Intermediate\Build\Android\Bengal\Development/UELinkerFixups.cpp:615: error: undefined reference to 'EmptyLinkFunctionForStaticInitializationSettings()'

_

~~~

C++ Android Development

Please review the documentation on developing for Android using C++.

There's probably a build.cs or target.cs adjustment that you need to make to the plugin to support android specifically. I can't add this to the general plugin since not everyone is building for android.

Epic Docs on Building for Android
https://docs.unrealengine.com/latest...nce/index.html

~~~

Android NDK Required for Plugin Builds

In particular please note that in order to compile C++ for Android you need these two additinal things, beyond building for BP only.

Android NDK
Enviro variable -> NDKROOT

~~~

Might want to wait for 4.8

Again once 4.8 rolls around it is likely that there will be an easier workflow for plugins in packaged games and not requiring as much C++ awareness or fancy components.

These issues have probably already been resolved because no one can purchase a C++ plugin and ship it to Android unless Epic has already resolved this issues.

~~~

Solution From Another User

Here's a solution mentioned by another user:

i had to rebuild the solution, and compile to the targets (android, ios, etc.) in shipping mode.
Now it works.
Thanks.

~~~

Additional Input Requested

I know there are people who have gotten my plugin to work great on Android, I'd love to hear their input on this matter as I've not been developing for Android in my own projects.
