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

[Jamendxman3]

Hi there!

Yes you definitely need to compile my template yourself, because you also cannot add code to it unless you compile it yourself!

You need Visual Studio Express 2013 for Desktop.

https://www.visualstudio.com/en-us/p...xpress-vs.aspx

Make sure to get the "Community" edition or the one that says "For Windows Desktop"

Install that, and then you can use VS to compile.

The only alternative to a C++ plugin would be to make a BP Library asset that you share with people.

Enjoy!

30+ New Nodes!
PS: I recently released 30+ new nodes for Math, 3D Geometric Analysis, and Physics!

I reinstalled my Visual Studio 2013, with the VS 2013 Ultimate for desktop, but how do I compile VictoryAI manually?

Hi there!

So step 1 is to turn your project into a project that has source code: (or see my note below!)

1. Create a new empty actor class in the editor via File->add code to project
2. Now you can close the editor and navigate to the folder containing your .uproject.
3. make sure you are storing my plugin template inside a folder called "Plugins" that is in this same directory as your .uproject
4. if you dont see a .sln file you can right click on your .uproject and select Generate VS Files
5. open the .sln that is created and build your project! ("build" from top menu bar)

Because your project is now setup to have source code, the Unreal Build Tool (UBT) will detect the plugin template and compile it along with the source code for your project.

Now you can proceed with modifying my plugin template, and then just keep recompiling your main project .sln file!

Please note, you can use any project to do this process, so you could even create a new C++ project that is really just to compile the plugin, and then use the plugin with your BP-only project.

Can you please make the next node to be a node that enable you to use external audio files like you did with the texture node ?

Sounds cool but I can think a few possible problems, such as UE4 only supports .wav.

What would be the use case though? curious

Well, if users could place their own texture packs, why not matching sounds as well?

I Want to give the user the ability to replace audio files for certain actions, like a shooting sound for example.
So the user can replace fire.wav with an other fire.wav and the game will play the current file.

Hey Rama,

thanks a lot for this great plugin!
Could the "Victory Save Pixels" node be extended in a way that it outputs a new Texture2d without saving the file to disk first?

edit: actually, get the pixels of a Texture2d, manipulate, and create a new Texture2d

Load .Wav From File and play it!

Dear Sahkan,

I already have these nodes for loading audios from file!

Does this give you want?

Holy **** ! you are a god ! Thanks XD

[mayaping]

Rama,Can you tell us how do you make the VictoryAI plugin template?

[Rama]

When I have some time I can work on this yes

TMaps, Mapping Two Data Types Together In BP!



Rama's Blueprints TMap Solution!

I've now made a BP TMap solution!

TMap is a data structure that is not yet exposed to BP, but I've made a component-based solution for you so that you can use TMaps in BP!

~~~

What's a TMap?

Really it's name is "Map" and T is the class specifier in C++, but I tend to call them TMaps since Map is a rather generic word.

A TMap is a data structure based on Key,Value pairs, where for any Key there is only one Value.

This allows internal data structure look up times that are much faster than a regular dynamic array.

This also allows for the association of dissimilar data types in a way that you organize.

For example, you can map a set of integers to a set of Vectors, so that each integer is related to exactly one vector.

Or, as I provide you with in my plugin, you can relate a String to an Actor!

This means you can look up an Actor reference via a simple string input!

Or you can look up Vector data based on String data!

The primary use of TMaps is for efficient lookup of data, which dynamic arrays simply cannot do because there is no guarantee or assumption with dynamic arrays of anything like a key,value where each key has only 1 value.

The rules of TMaps allow for efficient look up to speed up your game flow!

~~~

Actor Component

My solution is component-based, which means you can have per-instance TMap data for your game's actors!

You simply add my Victory TMap Component to any actor you want!

I used the My Character blueprint in my own tests!!!

You can use literally any actor you want, or make a new actor BP whose only role is to house the TMap Component

~~~

Supported Types



Supported TMap Functions





~~~

Additional TMap Combinations

If you find that you cannot use my existing set of TMap Combinations to fulfill your game's needs, let me know by posting in this thread and I can add additional TMaps to the component.

~~~

Per Instance

Remember that what I providing you with is a component-based solution, so you can add this TMap data to as many actors in your game as you want, and have per-instance variations in the data contained therein!

Anybody know how to hack this into 4.8 preview? :P - Testing it, it doesn't seem to be a simple drag and drop, Which was the case in 4.6 > 4.7.

[Sahkan]

I tried the "get sound wav from file" and it didn't work for me.
While "get texture from file" worked great, trying to get the wav files the exact same way and it gives me nulls.
Did someone try that node already?

Edit: Oh i see now. they files supposed to be in .ogg format, it wasn't that obvious though :\

[aWinter]

Thank you Rama, and everybody who ever contributed for this great Plugin, it's really awesome.

I have a question and a request:

In January you wrote on answerhub that it will be possible "very soon" to package BP only projects - is there any new information?

I really would love to see Apply Multiple Damage & Event Multiple Damage nodes. Similar to the current ones, but instead of a float as base damage it would carry a float array, so it may affect various attributes at once with different intensity - e.g. Life, Mana, Stamina. In addition it may also have a bool array and another float array for "is DoT (damage over time)" and "DoT (damage over time) duration". The Bool array is not really necessary, but it may be a bit more comfortable to work with.
