Bubble-sync

Visit the simple canvas experiment exploring tab synchronization through LocalStorage. Enjoy the synchronized movement of bubbles across tabs. A playful journey into web development skills.

Environment Management

• The project utilizes LocalStorage to save and load the environment state, ensuring data persistence.
• Screen boundaries and tab information are dynamically tracked and updated during runtime.
• The canvas is resized to match the current window dimensions, providing a full-screen interactive experience.

  • bubble.y (optional): Initial Y-coordinate of the bubble's center.
  • bubble.radius (optional): Initial radius of the bubble.
  • bubble.speedX (optional): Speed along the X-axis (change in X-coordinate per frame).
  • bubble.speedY (optional): Speed along the Y-axis (change in Y-coordinate per frame).
  • bubble.color (optional): Color of the bubble.

static randomColor(): string

Generates a random pleasant color in hsl format.

handleCollisions(screenBounds: Object): void

Handles collisions with screen edges.

• Parameters:
