A simple atlasting system for Raylib-py

The Atlas Project 📖

A specialized system that allows users to create an effective atlas system with Raylib-py! With the help of Python, Raylib-py and coffee, this simple module can help you optimize your game by reducing draw calls.

How to use 🚀

1. Installing:

• Install it with pip: pip install the-atlas-project

2. Importing:

• Import it to your project

# Import the AtlasReader class
from the_atlas_project import AtlasReader

3. Instance Creation

• Create an instance of the class and pass in the file name of your JSON Atlas properties (e.g. 'atlas.json')

# Create an instance of the AtlastReader class with it's respective arguments
atlas = AtlasReader("atlas.json")

• Note: The atlas properties file must follow this syntax in order to properly recognize the assets:

{
  "atlas": "assets/atlas.jpg",
  "entries": {
    "sprite1": {
      "x": 0,
      "y": 0,
      "w": 16,
      "h": 16
    },
    "sprite2": {
      "x": 17,
      "y": 0,
      "w": 16,
      "h": 16
    }
  }
}

• Explanation:
  • atlas is the name of your atlas picture.
  • entries are where your sprite entries reside. You must put your sprite entries within here.
  • sprite1 and sprite2 are custom names that you must assign in order to properly get use it in draw_sprite() later.
  • x, y, w and h correspond to x position, y position, width, and height respectively. This is important because this is how the module can actually find the texture.

4. Drawing:

• Finally draw the sprite with the draw_sprite() function and pass in the name of your sprite, corresponding to the atlas.json file, while also passing the x and y positions of where you want to place your sprite.
• Optionally, you can pass scaling arguments to scale your sprite with type float. The default scaling factor is 1.0

# Draw the sprite
atlas.draw_sprite("sprite2", 20, 20, scalex=5.0, scaley=5.0)

5. Unloading

• Ensure to unload the atlas after use with the unload() function. This ensure that no memory leaks can happen.

atlas.unload()
