dartboard-rendering

What problem does it solve?

This Skill provides implementation knowledge and best practices for rendering a darts board with p5.js, covering drawing order, layering, and coordinate system handling to guide implementation, testing, and reviews.

Core Features & Use Cases

• Drawing order principles: Outer-to-inner layering to ensure correct visuals.
• Two-step spider rendering: Draw spiders in two phases to avoid color bleed.
• Accurate segment angle placement: Use boundary-centered angle calculation to align segment borders with spider lines.
• Coordinate system separation: Work in physical coordinates and convert to screen coordinates at render time using a Transform utility.
• p5.js render optimizations: Set drawing state outside loops for performance.
• Implementation patterns: Functions like drawSpiderOuter and drawSpiderBull encapsulate rendering steps.

Quick Start

Apply the dartboard rendering guidelines in your p5.js project. Start by implementing the drawing order (outer rings, then spiders, then bull/segment numbers), split spiders into two steps, ensure coordinate transforms, and optimize rendering by configuring drawing state once outside loops.
