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

[maparizeau]

Thanks for the quick reply and considering you are doing this as a service to us, I very much appreciate. I will wait for 4.8 probably and go from there.

Keep up the good work

Lovely to hear from you maparizeau!

I really do think a whole lot of this sort of thing has been resolved by Epic already in preparation for plugins being sold on marketplace, so if your development $ and time can be used elsewhere I would indeed recommend waiting!

Wow Thanks Rama. This is really great. I am trying to export various strings to a file, for example the players x,y,z coordinates every second. I would like to save these to the same file however for each time point for a coordinate to be on a separate line or separate by a character e.g. ";". Do you know of a simple way to implement this with your SaveStringToFile Node?

I am trying to export this data to statistical software for analysis (for a psychology experiment that I hope to do within the Unreal engine).

Thanks, Eric

Thanks

Rama I figured out how to create an array of all the coordinates and then just save that array to a text file at the end of the play. See the Blueprints below as well as the player path graph that I created in R.

Hi,
what about plugin support for 4.8?

Hi,

Hi,

Rama has said (multiple times) that preview builds are not supported.
It's kinda pointless to update the plugin for every preview release (previews are for testing purposes anyway) just wait for the final 4.8 release and I'm sure the plugin will be updated

[Rama]

Woohoo!

Wow this is really neat grizfb75!

Thanks for sharing your research and BP development with us!

Thanks for the pics!

Stupid question, does this plugin auto update through UE4?

[Jamendxman3]

Hello Rama, I'm wondering whether or not the Victory Plugin needs these nodes?:

•Round vector to nearest multiple of wildcard, for example: round the x, y, and z's to nearest multiple of 50.
•Round float to wildcard decimal places.

Maybe once marketplace plugins are released that can happen!

Great to hear from you Jamendxman3!

Round vector as you are saying was added by TK-Master! It's called Grid Snap:

Being able to round a float to an arbitrary number of decimal places would indeed be useful!

I will work on that node soon as I can

Great suggestion!

Get Static Mesh Vertex Locations Using PhysX



~~~

Works in Packaged Games by using PhysX coding!

C++ Source Code For You! ♥ Rama

bool UVictoryBPFunctionLibrary::GetStaticMeshVertexLocations(UStaticMeshComponent* Comp, TArray<FVector>& VertexPositions)
{
	VertexPositions.Empty();
	 
	if(!Comp || !Comp->IsValidLowLevel()) 
	{
		return false;
	}
	
	//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;
	}
	//~~~~~~~~~~~~~~~~
	
	//Component Transform
	FTransform RV_Transform = Comp->GetComponentTransform(); 
	
	//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;
}

Alright, well to save you the trouble, I'll write you a short piece of code for rounding decimal places so you have to think less:

float FloatForRound = 3.14159265
int DecimalsToKeep = 5

FloatForRound = (int)(FloatForRound * 10^DecimalsToKeep) / 10^DecimalsToKeep

Obviously this doesn't round to nearest at the end, but you get the point in case you didn't automatically know what to do.

[Zeustiak]

Made a minimap with your Save Pixels node:



On the Save Pixels node, can you add an output for a texture2d object?

Also, the way your node pulls data from the array does not line up with my data structure. I basically need to be able to rotate it 90 degrees and then flip it horizontally. Would it be possible to add some orientation manipulation capabilities to the node or another node? Basically need the simple rotate options that MS Paint has: Rotate 90 Counter, Rotate 90 Clockwise, Flip Horizontal, and Flip Vertical.

The same options would be useful for your Load Texture nodes as well.

Oh dont worry, I already have the code I need, just have to write the node and update my plugin

Thanks though!
