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

[Shadowriver]

Rama, did you maybe considered creating custom UK2Node classes for all those TMaps and TPairs nodes? it would allow you to make all those nodes more type universal

[Rama]

Three New Nodes From Kris!

Save Image To Disk From Capture Component 2D

Save Image To Disk From Capture Actor

Load Image By Extension

~~~

Note on Using the Save Image Nodes

For the Save Capture Component 2D Image to Disk node, make sure to specify the image format you want by including the appropriate extension, such such as .bmp, .jpg, .png

If you are having trouble getting the image to save, try a different extension

~~~

Save Thumbnails / Snapshots from Capture Components!

Quoting Kris:

"You can see the result in the following picture.
Each of the thumnails are generated via a custom scene capture component, saved and loaded as required:


(Picture is from Kris's project called Ground Branch, http://www.groundbranch.com/ )


I'm passing them into a material to remove the background (green screening) and then using set brush material.

Should save people some time."

~~~

Thanks for the new nodes Kris!

Being able to save screenshots from a CaptureComponent2D in Blueprints is so very useful!

Improved Get Vertex Locations of Static Mesh

Now works in Packaged Games





My C++ Code For You

See my PhysX wiki for the basic build.cs setup:
https://wiki.unrealengine.com/PhysX,...o_Your_Project

Here is the code I wrote to get all of the transformed vertex positions using the Body Instance and PhysX code!

I am doing many safety checks to ensure the Body Instance data is valid before utilizing it, and the result is that now you can get accurate vertex locations in packaged games!

//~~~ PhysX ~~~
#include "PhysXIncludes.h"
#include "PhysicsPublic.h"		//For the ptou conversions
//~~~~~~~~~~~

//Get Transformed Vertex positions of any static mesh! -Rama
bool UVictoryBPFunctionLibrary::GetStaticMeshVertexLocations(UStaticMeshComponent* Comp, TArray<FVector>& VertexPositions)
{
	
	if(!Comp || !Comp->IsValidLowLevel()) 
	{
		return false;
	}
	//~~~~~~~~~~~~~~~~~~~~~~~
	
	//Component Transform
	FTransform RV_Transform = Comp->GetComponentTransform(); 
	
	//Body Setup valid?
	UBodySetup* BodySetup = Comp->GetBodySetup();
	
	if(!BodySetup || !BodySetup->IsValidLowLevel())
	{
		return false;
	}  
	
	//Get the Px Mesh!
	PxTriangleMesh* TriMesh = BodySetup->TriMesh;
	 
	if(!TriMesh) 
	{
		return false;
	}
	//~~~~~~~~~~~~~~~~
	
	//Number of vertices
	PxU32 VertexCount 			= TriMesh->getNbVertices();
	
	//Vertex array
	const PxVec3* Vertices 	= TriMesh->getVertices();
	
	//For each vertex, transform the position to match the component Transform 
	for(PxU32 v = 0; v < VertexCount; v++)
	{ 
		VertexPositions.Add(RV_Transform.TransformPosition(P2UVector(Vertices[v])));
	}
	
	return true;
}

Hey Rama,

thanks for this awesome work. I just downloaded your plugin.
But somehow is the BP GetRenderedActors not working. I thought I could use that one to detect all the actors my player can see. But even if the objects are clearly out of the players field of view, they are still listed as visible.
Am I missunderstanding something here?

Cheers Pascal

Get Rendered Actors

Get Not Rendered Actors!

Hey Rama,

thanks for this awesome work. I just downloaded your plugin.
But somehow is the BP GetRenderedActors not working. I thought I could use that one to detect all the actors my player can see. But even if the objects are clearly out of the players field of view, they are still listed as visible.

You're understanding is correct, I have now fixed my BP nodes, Get Rendered Actors, and Get Not Rendered Actors, to work correctly in 4.6.1!

Get my latest download and enjoy!

I've tested these node as now working correctly.

They will indeed tell you when actors are not being rendered by the engine, such as when you are facing the other way while in-game

You can use my Get Rendered Actors node to find out the entire set of actors that have components that are currently being rendered by the engine!

~~~

MinRecentTime

You can use MinRecentTime to adjust what qualifies as "Recent enough"

So if you use MinRecentTime = 2, my nodes will return all actors that were rendered within the past 2 seconds.

The default is really small because you generally just want to know which actors are currently being rendered, with no margin for "relatively recent."

Rama,

I have a simple mind. What is the proper way to use Get Rendered Actors or Get Not Renders Actors to cause an event on Character dropping from the screen. Should I use the ForEachLoop into a Contains Item to do boolean logic off my Character being found in Get Not Rendered? Do I need the ForEachLoop?

I'll play around with it tonight, just doing some reading now.

Thanks!

Victory BP Library is Upgraded to 4.7

Dear Community,

My Victory BP Library plugin is now upgraded to 4.7!

The only substantial change I had to make was for my sound volume node.

Here's the old and the new code.

bool UVictoryBPFunctionLibrary::VictorySoundVolumeChange(USoundClass* SoundClassObject, float NewVolume)
 {
	if(!SoundClassObject) 
	{
		return false;
	}
	
	SoundClassObject->Properties.Volume = NewVolume;
	return true; 
	   
	 /*
	FAudioDevice* Device = GEngine->GetAudioDevice();
	if (!Device || !SoundClassObject)
	{
		return false;
	}
	    
	bool bFound = Device->SoundClasses.Contains(SoundClassObject);
	if(bFound)
	{ 
		Device->SetClassVolume(SoundClassObject, NewVolume);
		return true;
	}
	return false;
	*/
	
	/*
		bool SetBaseSoundMix( class USoundMix* SoundMix );
	
	*/
 }

Known Issue

Undo/Redo in my Vertex Snap Editor feature is not working correctly in 4.7, if someone investigates this and fixes it let me know!

I will get to it as soon as I can. Rest of Vertex Snap Editor works great in 4.7 !

Rama

PS:

Woo! Let us know what you get from the store :P

It was too cold out, so I did the 4.7 upgrade instead !

[Sanborn]

Rama, I just installed 4.7 and created your Get Rendered Actors/Not Rendered Actors exactly and I am not seeing any strings being printed to the screen.

Can you double check on your machine that these work on 4.7?

Edit: Nevermind, I reloaded UE4 a second time and now it's working.

Just downloaded this to play with in 4.7. Seems ok. But when I do a developmental build and run the program it tells me it can not find the victory plugin and then the game crashes.

PS:

Thanks for your hard work on the plugin Rama! I really enjoy it.

For some reason the plugin does not work on my project in a 4.6.1 to 4.7 upgrade.

It says could not be compiled from source. When I remove the plugin it works without issues. I tried the last three versions of the plugin. Any ideas?


Edit: I'm checking Visual Studio right now.

'SetClassVolume' : is not a member of 'FAudioDevice'
'ULocalPlayer::ControllerId' : cannot access private member declared in class 'ULocalPlayer'
'IgnoreActors' : is not a member of 'FCollisionQueryParams'
error C2228: left of '.Empty' must have class/struct/union

Is the new version on the https://wiki.unrealengine.com/File:VictoryPlugin.zip page?

Thanks!

Could you help me?

If you review this thread, in a few posts back, someone else figured out that you need to include Android stuff in your .build.cs in order to compile my plugin for android

Here is that quote

You simply dont ship the binaries (dll) for Android, or iOS, or linux or mac ;P
So i had to rebuild the solution, and compile to the targets (android, ios, etc.) in shipping mode.
Now it works.
Thanks.

Greetings, Ed

If ed or someone else could provide their modified build.cs that would be great!
