Tobiasz2817 Since there is no concept of position in the Events that can be set in the Spine editor, I thought maybe what you were looking for were point attachments, so let me add something about that.
A point attachment is a point in space with a rotation. It can be used to spawn particles or anything else that involves a position and/or rotation. A bone could be used instead of a point attachment, but bones have other features like scale or shear that require a little more processing at runtime. In Unity, you can easily make any GameObject, such as a particle, follow the point by using the PointFollower component: https://esotericsoftware.com/spine-unity-utility-components#PointFollower
