javascript - Matter.Constraints：BodyB属性保持未定义(Matter.Constraints: BodyB property remains undefined)

Question

I'm using matter.js and trying to add an object (candy) with a Matter.Body to options.bodyB.(我正在使用something.js，并尝试将具有Matter.Body的对象（糖果）添加到options.bodyB中。)

The error logs show that candy exists, has a body, and yet bodyB is undefined.(错误日志显示糖果存在，具有主体，但bodyB未定义。) Here is the actual Candy class.(这是实际的Candy类。) And here is where I actually pass the Candy to the Rope in the main class.(这是我实际上在主班级将糖果传递给绳索的地方。)   ask by ze boris translate from so
