M3.1 Flash 单文件 Three.js 锦鲤池：鱼会游向食物
实测让 M3.1 Flash 在单个 HTML 文件里做可交互锦鲤池，鱼有不同花纹、水流动、可控制相机，点喂食后鱼真的转向食物而非循环动画；作者评价快且适合反复迭代的编程。
I gave MiniMax M3.1 Flash a pretty specific Three.js challenge: build a living koi pond in a single HTML file. I wanted moving koi with different patterns, flowing water, rocks, plants, camera controls, and a feed button where the fish actually swim toward the food. It got the whole thing working. What stood out was the behavior. The fish didn’t just keep looping the same animation. They reacted when food appeared and changed direction toward it. That made this a much better test than just asking for a nice-looking 3D scene. For me, this is where M3.1 Flash gets interesting: it’s fast, capable enough to handle real interaction logic, and much more cost-efficient for the kind of iterative coding work where you’re going back and forth a lot.
