[MattD]

Rama do you know that you're the patron saint of Unreal? <3 <3 <3 it works if I keep it project level only, but I'm okay with that!

How to get the Relative Path to your project Game Dir in a packaged game, anywhere on device



Dear Community,

A reminder of these extremely powerful nodes to help you access the directory structure of your game after it has been packaged and put wherever by your user!

Victory Absolute Paths!
Live as of March 3rd 2015 build

Get the File Path to your project .exe, your project root directory, and more!

These paths are dynamically updated even if you move the entire project to a new location on your computer!

All these nodes are fully compatible with packaged builds and return absolute paths!

These nodes also work in Development/Editor builds!

~~~

More Power For You in BP

Now you can easily create your own folders/files, relative to the project root directory or your project's .exe!

Please note that in editor builds, the .exe returns your UE4Editor.exe location, but in packaged games it returns your game's .exe



~~~

Recommendation:

I recommend using the Project Game directory for most of your relative path needs! This works the same in Editor and packaged builds!

You can also get your Saved and Logs folders for your project in both packaged and editor builds!

[MENTION=552]Rama[/MENTION], I think, there's a typo in your code on github. See this.

Shouldn't it be

Pixel.A = ((Pixel.R == ClearFColour.R) && (Pixel.G == ClearFColour.G) && (Pixel.B == ClearFColour.B)) ? 0 : 255;

instead?

Or simpler:

Pixel.A = Pixel == ClearFColour ? 0 : 255;

Hi there, welcome to the forums!

I am forwarding your comment to the person who authored that code for their review, it does appear that some modifications are needed

Yes, yes it should be (.R, .G, .B).
But not that latter (Pixel == ClearFColour), as we don't want the user to worry about the correct alpha, just the colour.

Thank you.

Oh, right. Silly me.

Anyway, thanks for the answer.

New Node, DateTime, UTCToLocal, and fix for CaptureComponent2D_SaveImage



Dear Community,

Kris's fix for CaptureComponent2D_SaveImage is in this newest build!

Also I am releasing my 2-day research project to you all! (My final solution took 5 min to figure out, but discovering the problem took much longer ).

Here I am giving you the ability to convert a UTC Date Time into your local time zone, at the time of the execution of the code (not hardcoded in BP or anywhere).

This node retrieves the local time of your computer, and the current UTC time, and uses that offset to take any UTC time and convert it to your/the end user's local time zone!

This is very important for any time you can only get times in UTC but need a BP node to convert to the user's local time!

I needed this for my Rama Save System Plugin to allow people to get a File Time stamp in local time!

And I am giving this research of mine to you as part of Victory Plugin (source code is included in the complimentary download)

~~~

C++ Code

Here is the code I figured out to do this dynamic UTC to Local conversion in very succinct fashion!

Note I return by Reference for maximum memory efficiency

UFUNCTION(BlueprintPure, Category = "Rama Save System|File IO")
static void UTCToLocal(const FDateTime& UTCTime, FDateTime& LocalTime)
{    
	//Turn UTC into local ♥ Rama
	FTimespan UTCOffset = FDateTime::Now() - FDateTime::UtcNow();
	LocalTime = UTCTime;
	LocalTime += UTCOffset;
	//♥ Rama
}

New BP nodes for MD5 Hash File Verification, Verify your game's downloaded patch files!



Dear Community,

I've just release 2 new nodes that help you to do MD5 file verification on your downloaded files!

What are MD5 Files For?

MD5 hashes of files enable you to verify the data integrity of files that your users download from the internet.

You generate your own MD5 from original file, and then distribute the MD5 file (1kb in size) to users along with the much larger download file.

After your user downloads your game's patch files or other important files, then you can use my BP nodes to compare the downloaded file hash with the md5 you gave to the user, to verify the file's integrity!

The result:

With my BP nodes you have a way to check actual data integrity of a downloaded file, not just whether the time and file size match, this gives you binary data integrity verification powers

Rama, I'm sorry, but I still don't understand, how to enable snap mode in your plugin.
I have downloaded, and I correctly installed plugin and I have enabled it in Plugins in UE. But... How can I enable snapping mode in viewport window?

Ahh sorry, please see these docs:

https://wiki.unrealengine.com/Rama%2...ertex_Snapping

You have to add the lines to your config file, DefaultEngine.ini, so that the engine knows where to find the custom editor mode
