// 初始化3個對象 MNKBufferOne, MNKBufferTwo, MNKBufferThree 並在class屬性中分配它們 buffers this.buffers = { MNKBufferOne : this.addBuffer(), MNKBufferTwo : this.addBuffer(), MNKBufferThree:this.addBuffer(), }; // 在方法中 onInit 或者 onUpdate 我們通過解構得到這些對象 const {MNKBufferOne, MNKBufferTwoб MNKBufferThree} = this.buffers;
