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

Bad_Imp_Studios · January 18, 2022, 1:15pm

You are welcome, has been integrated into future versions?

Rama · January 19, 2022, 1:07am

I have a link now for people in the original post, but after I add a chunk of new features I would appreciate you recompiling, as I do not have a post-4.24 setup going yet

I might have a fun new update within 24-48 hours so please check back periodically, or I might pm you if you want to help advance our Victory on the platform.

Get Text From Any Running .EXE on Your Computer!

URamaVictoryPluginCreateProcessPipe is Born!

Below is a picture of me capturing the output of a .exe on my computer, a video compression tool, HandBrake!

The output of STDOUT of the .exe is coming directly into UE4, using only Blueprints!

!

Again, welcome to the UE forums @richhelvey !

!

I’ve made a new version of the Victory Plugin ( 4.27 (win32, win64 only) in original post ) !

new version allows you to create a Very Special URamaVictoryPluginCreateProcessPipe to capture your Process output, if the Process is outputting to STDOUT (console window) or STDERR

Construct the RamaVictoryPluginCreateProcessPipe
Pass it into VictoryCreateProc
Call ReadFromPipe on the periodically to get updates from your process
When , please call ClosePipe on the , and null the reference to the (I call ClosePipe inside of BeginDestroy, but might as well take initiative yourself and close the actual OS pipe yourself immediately, rather than waiting for Garbage Collection)

Relevant UE4 C++ Code

Please add ‘Array Sort’ node to the UE5 version, I need the node that sorts structs by a variable name ‘Array Sort’.

Rama · February 3, 2022, 5:18am

Was Array sort actually working for you in UE4.27 ? The contributor to the Victory plugin who made that node would be able to help, Mr Redbeard, but I thought the node had been non-functional for a while, and I don’t recall why.

Victory to You @Tbjbu1 !

Tbjbu1 · February 3, 2022, 3:46pm

It was working for me in 4.26, not sure about 4.27 - never used that version.

s54780478 · February 3, 2022, 3:55pm

I’m looking for a manual too~

Rama · February 4, 2022, 4:39am

Good to know thank you, I will investigate!

Do you have a specific question, what sort of manual did you have in mind?

markwong · February 4, 2022, 6:57am

Hi, I have question regarding the SaveArrayToFile, is there an example of how to format it as row and column for csv file?

uJelleh · February 22, 2022, 10:41pm

@Looks like my UE5 release prediction was pretty spot on

I’m trying to get a copy of our project working in UE5 Preview. So far I’ve gotten most of the levels to open fine, but if I try opening any blueprints (or even create a new blueprint > actor from scratch) I get crash immediately:

Assertion failed: NewOperatorInputA [File:D:\build\++UE5\Sync\Engine\Source\Editor\BlueprintGraph\Private\K2Node_CommutativeAssociativeBinaryOperator.cpp] [Line: 281] (the line is: check(NewOperatorInputA);

I searched online for “K2Node_CommutativeAssociativeBinaryOperator.cpp” and saw a few references to the Victory plugin, hence why I’m posting it here (I realize it’s an engine file, but from my search results of other people having an error with cpp file, they mentioned the victory plugin)

I know UE5 Preview literally JUST came out today, so I’m not expecting an immediate update, just thought I’d post here in case it’s useful

UPDATE: Fixed it!! It was the “Append Multiple” node that I found was added to one of our widgets that was causing the crash in the UE5 Preview project (now replaced with the regular append node).

Hi. I started using the Victory plugin for getting RGB data from a texture.
I downloaded and installed the “Lemur_hotel” version, which is the only compiled version I could find, because www. is dead and github does not
I’m using UE4.27 on Win64
I tried the node GetPixelFromT2D to get pixels from a texture, but it returns only zero RGBA and the deprecation message " function will not work until I figure out how to update it to 4.25, if you need it urgently, please post in my ue4 forum thread for plugin"
Is there a fix for 4.27?

anonymous_user_ebb8f4eb · March 1, 2022, 4:14pm

In fact T2D functions either don’t work or crash ue4.27
I need to get the pixels coming from a video input texture, so loading from a file (the only thing that works) is not an option…

is the crash report I get when calling VictoryGetPixelsArrayFromT2D blueprint with a 1024x1024 texture in VectorDisplacementMap mode
The plugin is installed in the project plugin folder, not in the engine plugins.

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000002

Hi there! @anonymous_user_ebb8f4eb welcome to the UE4 Forums!

The solution to your is here:

Same logic applies to the UE4 version (you don’t have to upgrade to UE5, just set your T2Ds to no mip maps and use vectordisplacement, results in no compression of your texture, so you have a 1 to 1 pixel ratio between your original file and the UE4 file, annnnnd, no crash

Rama · March 8, 2022, 8:14am

Each array line = 1 row
Each comma = 1 column

so if your csv file looks like

Name, Favorite Flower, Favorite Color

Name,Favorite Flower,Favorite Color
You,Tulip,Yellow
Me,Rose,HotPink
Sjoerd,StrawberryFlower,Red

then each of your String array entries should have 2 commas, and each array entry represents 1 row, you should include Column labels as your array 0 entry.

Don’t add line terminators in your UE4 string array, I add the line terminator in the C++ for you!

FString FinalStr = "";
for(FString& Each : SaveText)
{
	FinalStr += Each;
	FinalStr += LINE_TERMINATOR;
}

PITCHAYAKORN · March 10, 2022, 3:40am

I try to use Victory create proc on UE4.7 but the input argument line is not written to the command line windows and the process hold the empty command line window
could anybody give me some instruction

Floh · March 10, 2022, 4:55am

Removing victoryBP nodes from my project and disabling the plugin corrupts a bunch of my blueprint files…

Enabling the plugin again fixes it.

I can’t package my project because of an error with the plugin, that i’m not even using, which if disabled and removed, breaks my project…

Do I just need to start a new project and start over?

Anonymous_57339a53b18173d74e1e64c05a6f8114 · March 17, 2022, 1:03pm

Hey, first thanks for , Amazing Plugin!, 2, i try to Load Textfiles, and looks like , Ä,Ö,Ü are replaced by “?”, but on the node is " it supports Unicode characters" ?

Emrebel · March 22, 2022, 3:37pm

I have been facing to deploy on Quest.
I checked the adb log and it says : Failed to load ‘Apex Destruction plugin’.

I am confused with part as there is a filter for APEX EXCLUSION in Build.cs:

if (Target.Platform != UnrealTargetPlatform.Android && Target.Platform != UnrealTargetPlatform.IOS)

But it still tries to load the ApexDestruction plugin.

I also set the flag for plugin to false in uplugin file. The app loads but it is stuck at loading screen.

Please help if someone can provide any pointers on .

EDIT:

Here is the portion of the adb log:

Did you check my version of the plugin I uploaded for Quest? Google Drive: Sign-in

Emrebel · March 23, 2022, 3:35pm

I have downloaded the plugin from the Drive link you have shared before for Android:

I am not sure about the one you have linked now: It say ‘You need access’.
