5. Anti-Patterns & Gotchas
5. 反模式与注意事项
❌ Anti-Pattern 1: Heavy Computation in draw()
draw()❌ 反模式1:在draw()
中进行大量计算
draw()What it looks like:
- Creating 10,000 objects every frame.
- Resizing array every frame.
Why it fails:
- FPS drops to 5. Browser hangs.
Correct approach:
- Pre-calculate: Generate static geometry in .
setup() - Pool Objects: Reuse particles instead of .
new Particle()
表现:
- 每帧创建10000个对象。
- 每帧调整数组大小。
问题所在:
- FPS降至5,浏览器卡顿。
正确做法:
- 预计算: 在中生成静态几何图形。
setup() - 对象池: 重用粒子对象,而非每次创建新的。
Particle()
❌ Anti-Pattern 2: Ignoring Resolution
❌ 反模式2:忽略分辨率
What it looks like:
- Hardcoding .
width = 500 - Art looks pixelated on Retina screens.
Why it fails:
- Looks bad on high-DPI monitors or prints.
Correct approach:
- (or higher).
pixelDensity(2) - Use relative units () instead of absolute pixels.
width * 0.5
表现:
- 硬编码。
width = 500 - 艺术作品在Retina屏幕上显得像素化。
问题所在:
- 在高DPI显示器或打印时效果不佳。
正确做法:
- 使用(或更高)。
pixelDensity(2) - 使用相对单位(如)而非绝对像素值。
width * 0.5
❌ Anti-Pattern 3: Pure Randomness
❌ 反模式3:纯随机
What it looks like:
fill(random(255), random(255), random(255))
Why it fails:
- "Clown vomit" aesthetic. No cohesion.
Correct approach:
- Curated Palettes: Pick 5 colors and stick to them.
- Constraints: Randomness should be the spice, not the meal.
表现:
fill(random(255), random(255), random(255))
问题所在:
- 呈现“杂乱无章”的视觉效果,缺乏协调性。
正确做法:
- 精心设计调色板: 选择5种颜色并坚持使用。
- 添加约束: 随机性应作为点缀,而非核心。
