如图有个boundingbox,每0.1秒都会变换位置
COCOS3.8.4,怎么获取当前帧这个boundingbox的4个顶点位置,从而做一个多边形碰撞体?
解决了,之前某个帖子传了空数组arr进去,不行
let slot = this.spine.findSlot(“root”);
var vertexAttachment: sp.spine.VertexAttachment = this.spine.getAttachment(“root”, “root”) as sp.spine.VertexAttachment;
var arr = (vertexAttachment.vertices as Array).concat();//这里不能传空数组进去
vertexAttachment.computeWorldVertices(slot, 0, vertexAttachment.worldVerticesLength, arr, 0, 2);
console.log(arr);
