Float32Array.of( element0[, element1[, ...elementN]] ) Creates a new typed array from a variable number of arguments. var arr = Float32Array.of( 1.0, 2.0 ); // returns <Float32Array>[ 1.0, 2.0 ] Float32Array.prototype.copyWithin( target, start[, end] ) Copies a sequence of e...
And the object has.at(n)method so you can random-access each element. This is the equivalent of subscript inArray. It was previously named.nth()but it was renamed to.at()alaArray.prototype.at()in ES2020..nth()still available for backward compatibility. ...

下一步，通过使用Array.from我们将类型化数组转换为JavaScript数组，数组中包含我们提取帧中三种姿势的概率。如果既不是踢腿也不是拳击的姿势的概率高于0.4，我们将返回站立不动。 否则，如果显示高于0.32的概率拳击，我们会向MK.js发出拳击指令。 如果踢腿的概率超过0.32，那么我们发出一个踢腿动作。以下就是完整的...
