Yes, you can dynamically add events to an animation through code. To do this, you would need to create an EventTimeline and add it to the animation's timelines. You can then add keyframes to this event timeline at the specified times. This allows you to trigger events at specific times during the animation. To remove an event, you would need to modify the EventTimeline to remove the specific keyframes or the entire timeline if needed. This process can be done programmatically, but it requires managing the timelines and events manually in your code.

You can simply create a new EventTimeline and Event and then set that event to a specific frame with the setFrame method. Then, add the timeline to a specific animation's timelines.

You may want to refer to the spine-cpp code to see how the timeline of events works:
