BlueWin is an Unreal Engine plugin that allows you to easily call various Windows functions directly from Blueprints. It comes with 13 C++ functions, fully editable and flexible.
Features ⚙️
Access to the taskbar: Interact with the taskbar by flashing the app icon or displaying a progress bar.
Folders and files interactions:, Check if they exist and search inside file.
Windows Interactions: Open Notepad with custom arguments, spawn a Message Dialog Box, and retrieve useful values such as Windows version, desktop path, your app’s PID, and more.
Just an advice for anyone looking to use this. The plugin presents a major security issue - each blueprint will now be able to execute any code on players’ machines. This means every UE mod file, which at first glance doesn’t contain any executable code, will be able to silently run programs. This in turns means the usual security issues - taking over client machines, creating bot farms, stealing data etc. By using this, you open your users to real-world threats and you might be legally responsible.
Hi, after careful consideration, I updated the plugin and removed the features that could be used in a wrong way, while keeping the safer ones. Thanks for pointing this out. <3
What does this mean exactly? What have you removed and/or changed? I’ve already used this to test some functions, does that mean I’ve opened up my pc to high risks?
Hi! Don’t worry your PC is not at risk.
The older version only had some functions that could potentially be misused if someone intentionally tried to write or delete files in dangerous locations, but the plugin itself does not do anything harmful on its own.
I’ve now removed all file and folder creation/deletion functions, as well as the ability to launch external executables, just to make sure it’s 100% safe for everyone.
If you only tested it normally (for example, creating or reading files manually), there’s absolutely nothing to worry about.
The new version just focuses on safe features like checking if a file or folder exists, interacting with the taskbar, showing message boxes, and getting system info.
If you have an old version I strongly recommend you to update the plugin
