| | Quickstart, command line method (Windows/Linux)

• Clone the tutorials' repository:
  • git clone https://github.com/harfang3d/tutorials-hg2.git
• Enter the repository:
  • cd tutorials-hg2
• Compile the tutorial resources:
  • python3 -m harfang.bin assetc resources
  • After the compilation process finishes, you should see a resources_compiled folder next to the resources folder.
• Run the tutorials:
  • D:\tutorials-hg2>python3 draw_lines.py

| | Quickstart, drag & drop method (Windows)

• Download the tutorials https://github.com/harfang3d/tutorials-hg2 and unzip them to your computer (eg. d:/tutorials-hg2).
• To compile the tutorial resources, download assetc for your platform: https://dev.harfang3d.com/releases/
• Drag and drop the tutorial resources folder on the `assetc executable -OR- execute assetc passing it the path to the tutorial resources folder (eg. assetc d:/tutorials-hg2/resources).

After the compilation process finishes, you should see a resources_compiled folder next to the resources folder. You can now execute the tutorials from the folder you unzipped them to.

``D:\tutorials-hg2>python draw_lines.py``

Alternatively you can open the tutorial folder and run the provided debug targets using Visual Studio Code <https://code.visualstudio.com/>_
