cocos creator 2.4.8通过sp.spine.SkeletonBounds以及sp.spine.BoundingBoxAttachment.computeWorldVertices()获取的包围盒不准确

Creator 2.x
#1

  • Creator 版本： 2.4.8

  • 目标平台： GoogleChrome

  • 重现方式：通过sp.spine.SkeletonBounds或sp.spine.BoundingBoxAttachment.computeWorldVertices()获取到的包围盒信息更新到碰撞体后不准确
    我贴一下源码：
    @property(cc.Prefab)

    bone_mark = null;

    private spine: sp.Skeleton = null;

    private spine_collider_list = [];

    protected onLoad(): void {

      this.spine = this.node.getComponent(sp.Skeleton);

  this.init_bone_message();

    }

    init_bone_message() {

      var bound = new sp.spine.SkeletonBounds();

  bound.update(this.spine._skeleton, true);

  var slots = this.spine._skeleton.slots;

  for (var i = 0; i < bound.boundingBoxes.length; ++i) {

      var attachment: sp.spine.BoundingBoxAttachment = bound.boundingBoxes[i];

      for (var j = 0; j < slots.length; ++j) {

          if (attachment == slots[j].attachment) {

              //匹配

              this.spine_collider_list.push({ "attachment": attachment, "listener": this.create_bone_node(slots[j].bone.data.name) });

          }

      }

  }

    }

    find_bone(bone_name) {

      var attach_util = this.spine.attachUtil;

  var bone_nodes = attach_util.generateAttachedNodes(bone_name);

  return bone_nodes[0];

    }

    create_bone_node(bone_name) {

      var bone_node = this.find_bone(bone_name);

  var item = Icarus.instantiate(this.bone_mark, "", bone_node, cc.Vec2.ZERO, cc.Vec2.ONE, 0, bone_name + "_mount");

  return item.addComponent(SpineAutoUpdatePolygonColliderListener).init(this);

    }

    collision_enter(other) {

      //这里需要整理过滤一次避免单个物体同时触发多个部件的碰撞

    }

    update_vertex() {

      var bound = new sp.spine.SkeletonBounds();

  bound.update(this.spine._skeleton, true);

  for (var i = 0; i < bound.boundingBoxes.length; ++i) {

      var attachment: sp.spine.BoundingBoxAttachment = bound.boundingBoxes[i];

      for (var j = 0; j < this.spine_collider_list.length; j++) {

          if (this.spine_collider_list[j].attachment == attachment) {

              var vertex_array = [];

              for (var k = 0; k < bound.polygons[i].length; ++k) {

                  vertex_array.push(bound.polygons[i][k]);

              }

              for (var k = 0; k < vertex_array.length; ++k) {

                  if (!this.spine_collider_list[j].listener.Collider.points[k]) {

                      this.spine_collider_list[j].listener.Collider.points.push(cc.Vec2.ZERO);

                  }

                  this.spine_collider_list[j].listener.Collider.points[k].x = vertex_array[k * 2];

                  this.spine_collider_list[j].listener.Collider.points[k].y = vertex_array[k * 2 + 1];

              }

          }

      }

  }

    }

    protected update(dt: number): void {

      this.update_vertex();
