Creating a Physics-based Animation with P5.js

TLDRLearn how to create a physics-based animation using P5.js. This tutorial demonstrates the process of designing a P5.js sketch by drawing the components of the Coding Train logo and using JSON files to store coordinates and colors. The animation utilizes the Matter.js physics engine and introduces the concept of subclasses and wrapper objects.

Key insights

🎨Designing a sketch in P5.js involves drawing individual components using coordinate points and colors.

🔌JSON files can be used to store and access coordinate data and color values for different elements of the sketch.

🔮The Matter.js physics engine allows for the creation of physics-based animations in P5.js.

💡Subclasses can be used to define specific types of objects, such as line segments and circles, within the sketch.

📦Wrapper objects can be used to encapsulate physics bodies and simplify the creation and manipulation of objects in the sketch.
