QRNative C++

C++ Source Code for Godot Engine 4.x GDExtension module exposing interfaces to encode and decode QRCodes in GDScript.

Usage

func _ready() -> void:
    # Decoding
    var qr: Image = Image.load_from_file("res://qrcode.png")
    var qr_decode_result: QRDecodeResult = QRNative.decode_image(qr)
    if qr_decode_result.is_valid():
        print(qr_decode_result.get_content())
    
    # Encoding
    var qr_content: String = "This is the content of my QR Code!"
    var qr_code: Image = QRNative.encode_string(qr_content, 100, 100, 5)
    $QRCode.set_texture(ImageTexture.create_from_image(qr_code))

Getting started / Building the extension

VSCode Compilation (only applicable if you are using VSCode as your code editor)

For the initial build you can run the vscode task initial-build-extension. This compiles both godot-cpp and the extension. For all subsequent builds, you only need to run the task build-extension.

Manual Compilation

To compile the extension you need to follow these steps:

1. Clone the extension recursively from this repository

# --recursive to automatically load the submodule godot-cpp
# The git adress can be found under the green "Code" dropdown menu
git clone --recursive (--GITHUB ADRESS--)

2. Make sure you are in the top level of the repository

pwd
.../qrnative

3. Go inside the godot-cpp folder

cd godot-cpp

4. Compile godot-cpp and generate bindings (only need to do this once when starting development or when there is an update of the submodule)

scons #by default will use your target and template_debug

5. Go back to the top level of the directory

cd ..

6. Compile the extension

scons
