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

As always, thank you ! Very useful stuff.

You’re welcome !

Let me know how your save system goes!

@Everyone

Have fun with my fully Config File BP node system!

Let me know how you use it!

:slight_smile:

Thank you -
Your plugin is making my and (I assume) the lives of many here easier with every release!
You really deserve a medal for your contributions :smiley:

Greetz,

Rename Save file

Your plugin is awesome, its helping a lot with our projects.
Right now we are trying to rename a saved file through FPlatformFileManager and going through your tutorial on File Management, we can’t figure out how to rename a saved file. Can you please guide us how to do that?

Thanks,

I’d like to ask here, what do you need to do to have a packaged content only project work correctly when using Victory plugin?
When I try to run my compiled project it crashes, telling me “Plugin ‘VictoryPlugin’ failed to load because module ‘VictoryBPLibrary’ could not be found”.
I’ve looked through the wikipage and searched answerhub/ thread but haven’t found anything telling me why is occurring?
To use the VictoryPlugin are you required to compile with C++ or something? I’d really appreciate some help with .

EDIT:
Forgot to mention I noticed there are VictoryBP binaries found in the .zip, however they are only for 64 bit. Are these files you need to place somewhere, and if so does that mean the VictoryBP plugin won’t work on a 32bit system?

Really Easy Way To Package Victory Plugin

Until 4.7, you do need to add code to your project, you can add an empty class of your choosing using File -> Add Code To Project.

I have a tutorial on here!
https://wiki.unrealengine.com/How_to_Convert_a_BP/Content_Project_to_a_C%2B%2B_Project_in_8_Steps


**4.7**

Once 4.7 rolls around we should no longer have to do  conversion to C++ for packaging plugins, [according to Epic  Marsh](https://forums.unrealengine.com/showthread.php?25009-Plugins-Are-Only-Working-For-People-in-a-Package-Game-if-they-have-C-Project&p=179085&viewfull=1#post179085).

Enjoy!



PS: You will need Visual Studio 2013 for Windows Desktop, see my wiki mentioned above

You’re welcome !

Great to hear from you!

:slight_smile:

When you say save file, you mean the .sav files generated by Epic using the BP Save System?

I presume you’d like a BP node to rename save file, you are not talking about using C++ right?

Rename Files

is what I am trying to do, I am rendering out different buffer Visualization passes in an Sequence PNG files using Matinee Movie Option and it works fine but the only problem is, it always name it “MovieFrame#####” and I want to change that to like “RoughnessPass##”, “AmbientOcclusionPass##” so after outputting those files, I want to write a function where it iterates through those files and rename it.

Thanks,

First off, great plugin. It seems like it’s really helping out.

My is that if I run my game as a server, it crashes immediately, saying “Cast of NULL to blueprint failed.” doesn’t happen if I remove the plugin. Any ideas? :confused:

Can you give me the whole crash log?

Do you mean using ?listen or as dedicated server?

Please load the editor / run the game from commandline with -log and send me the whole log after verifying the date and at the top of the log as being your must recent test.

I run games as a listen server the without any issues with the plugin :slight_smile:

So I need more info!

Check out these wikis of mine!

I share code for how to iterate over files and directories!

's Multiplayer Game Mode Solution

Find Player Start

Choose Player Start

Can Player Restart

These core Multiplayer functions are now fully implementable/overridable in Blueprints![/SIZE]**

I have found a solution for the of implementing FindPlayerStart, ChoosePlayerStart, and CanPlayerRestart in Blueprints!

And I’ve tested it as working!

**You can now implement core network coding of choosing player starts entirely in Blueprints!
**


**How To Use**

In my picture below I show how to use my Game Mode overrides!

1. **First make a new BP and select my VictoryGameMode class** which comes with my Victory BP Library (make sure you have the latest download https://wiki.unrealengine.com/File:VictoryPlugin.zip)

If you already have a Game Mode BP, choose File -> Reparent and use my Victory Game Mode BP


2. Make sure you are using my Victory Game Mode in your **World Settings**!

3. Setup the Victory Game Mode BP the same as my picture below!

4. Celebrate! You can now implement core multiplayer logic in Blueprints!

CPP Override and CPP Override Var

Please note the notation I am using, any variable that has CPPOverride Var in its name is used only with the corresponding event. is how I enable you to implement core multiplayer coding logic in Blueprints!


**Simple Data Types**

Please note that for the function that is designed to return a boolean value, CanPlayerRestart, you must pass the boolean and also a special variable, **CPPOverride SelfReference**,  is how you tell the CPP that you are implementing the Game Mode function in BP!

Non Destructive Solution

My solution is entirely optional and if you do not implement the event in Blueprints, and your programmer does it in C++, my solution will not interfere at with your existing code base!


**Log Message**

If you do implement my solution in BP, I am printing log information to indicate , so you/your programmer knows you are using a BP override and any C++ code will not be run.

C++ Code

Here is my C++ code for FindPlayerStart which shows how I worked around the of overriding FindPlayerStart via Blueprints!

Again I’ve tested as entirely working in PIE and commandline games!

.h



//Find Player Start
public:
	/** Use  var inside the body of CPP Override ~ Find Player Start event to override the C++ functionality! */
	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category="Victory Game Mode")
	AActor* CPPOverrideVar_FindPlayerStart;
	
	/** 
	 * Use CPPOverrideVar_FindPlayerStart inside of  event to implement FindPlayerStart in BP ! <3 
	 *
	 * Return the 'best' player start for  player to start from.
	 * @param Player - is the AController for whom we are choosing a playerstart
	 * @param IncomingName - specifies the tag of a Playerstart to use
	 * @returns Actor chosen as player start (usually a PlayerStart)
	 */
	UFUNCTION(BlueprintImplementableEvent, meta=(FriendlyName = "CPP Override ~ Find Player Start"))
	virtual void CPPOverride_FindPlayerStart();

	virtual class AActor* FindPlayerStart( AController* Player, const FString& IncomingName = TEXT("") ) override;


.cpp



//Find
AActor* AVictoryGameMode::FindPlayerStart( AController* Player, const FString& IncomingName )
{
	//Clear any previous to indicate whether BP did an override
	CPPOverrideVar_FindPlayerStart = NULL;
	
	//=======================
	//BP Hook by 
	->CPPOverride_FindPlayerStart();
	//=======================
	
	if(CPPOverrideVar_FindPlayerStart) //Did BP programmer set the var?
	{ 
		//Indicate that the BP override was found and is being used.
		UE_LOG(VictoryGameModeLog, Log, TEXT("

"));
		UE_LOG(VictoryGameModeLog, Log, TEXT("FindPlayerStart: CPP override found in %s and used instead of C++ implementation"), *GetName());
		UE_LOG(VictoryGameModeLog, Log, TEXT("

"));

		return CPPOverrideVar_FindPlayerStart;
	} 
	 
	//Default C++ Implementation
	return Super::FindPlayerStart(Player,IncomingName);
}



**Enjoy!**

60+ Extra BP Nodes For You!

No c++ required!

No compile required!

Download and plug in!

Latest plugin download is here:

:slight_smile:

**Two Nodes For You!

Get Path

Load From Asset Path!**

Now you can use Right Click -> Copy Reference and past that into my BP node to load an directly from asset path!

You can also pass in a UObject to retrieve its full asset path using my other node, and these two nodes work together!

I used system in my C++ based In-game editor to load levels from hard disk!

I simply save out the asset paths and then load objects from their paths, setting any user-changed variables!

**Now you can do the same thing entirely in Blueprints!
**
Enjoy!

Latest Victory BP Library Plugin Download

**Get Widgets of Class

Ideal for UMG Level Transitions**

I needed node for Solus and so I am now sharing it with you!

The was that I could not save a reference to my new widget because it is loaded and then a level change occurs which resets my HUD variables.

So I needed to access the widget after it was created dynamically, not relying on stored references within the HUD class.

I also did not want to have to store a reference to it in my Game Instance class cause then that leads to garbage collection issues.

I had to make the node for my own use and I have tested it as working in Solus!

**Now you can retrieve an array of any type of user-made UMG widget that is currently in your game at any!
**

C++ Code

Here’s what my C++ for node looks like!



void UVictoryBPFunctionLibrary::GetAllWidgetsOfClass(UObject* WorldContextObject, TSubclassOf<UUserWidget> WidgetClass, TArray<UUserWidget*>& FoundWidgets)
{
	//Prevent possibility of an ever-growing array if user uses  in a loop
	FoundWidgets.Empty();
	//~~~~~~~~~~~~
	 
	if(!WidgetClass) return;
	if(!WorldContextObject) return;
	 
	UWorld* const World = GEngine->GetWorldFromContextObject(WorldContextObject);
	if(!World) return;
	//~~~~~~~~~~~
	
	for(TObjectIterator<UUserWidget> Itr; Itr; ++Itr)
	{
		if(Itr->() != World) continue;
		//~~~~~~~~~~~~~~~~~~~~~
		
		if(Itr->IsA(WidgetClass))
		{
			FoundWidgets.Add(*Itr);
		}
	}
}

I’m sorry if I sound ignorant, I just registered and I’m checking out how the blueprint system works, but I’d like to ask a question about your plugin. Why is it a plugin and not integrated into the engine? I mean things like vertex snapping are awesome and honestly I’m surprised that it wasn’t in the editor by default. And it seems like you’ve expanded the blueprint system quite a bit, so what gives? Again I’m sorry if the answer is obvious,I just don’t know how things are running here. I come from Unity and everything there was in the asset store, I guess I had the wrong idea how open source works.

I had a hard understand , but I give it a try…

I guess your question is why isn’t directly added to the Unreal Engine source code, right?
Keep in mind open source doesn’t mean everyone can directly get his code into the engine (or a project for that matter) without hesitation. Open source means that you have access to the full source code and can edit it yourself, but not that you can contribute your code directly to the “root” project.

In the case of the UE4: there is a control instance by/from Epic. They check the contributed code and make sure that it works on platforms and in every way, which in my opinion is a good thing as it keeps out crappy code even though it costs.

Some of the additions of his work are, as far as I know and heard it, getting integrated into the engine, but that takes as the code has to go through quality assurance and the other stuff which Epic puts third party code through.

I hope that I got it right, if not just tell me I will try to correct the post then ^^

Greetz,

That’s an excellent answer to my question. Thank you.

Great answer !

I agree, although it means it takes longer to get code integrated, Epic’s quality assurance standards are really important! :slight_smile:

Great to hear from you Kensei!

Yes I do wish my vertex snapping would get integrated the but the engineers at Epic responsible for handling such matters have been rather exceedingly busy lately.

I hope they get to it one day, I already did the work for them!
