匹配node.fillColor（SKShapeNode）

Question

我在屏幕上有25个圆圈，每个圆圈都有一个随机颜色，该颜色是根据声明的颜色生成的，每个名称都包含在“CIRCLE_1＆＃39;”＆＃39; CIRCLE_2＆＃39;等

将node.fillColor与预定义颜色匹配时，只有Yellow返回一个值。其他一切都保持在0。

无法看到我做错了什么/错过了什么。

let SDRed = SKColor(red: 255/255, green: 61/255, blue: 61/255, alpha: 1.0)
let SDBlue = SKColor(red: 0/255, green: 175/255, blue: 255/255, alpha: 1.0)
let SDYellow = SKColor(red: 255/255, green: 255/255, blue: 0/255, alpha: 1.0)
let SDOrange = SKColor(red: 255/255, green: 128/255, blue: 0/255, alpha: 1.0)
let SDPink = SKColor(red: 255/255, green: 105/255, blue: 180/255, alpha: 1.0)
let SDGreen = SKColor(red: 144/255, green: 238/255, blue: 144/255, alpha: 1.0)
let SDDodgerBlue = SKColor(red: 30/255, green: 144/255, blue: 255/255, alpha: 1.0)
