The functions found in this section are only for use with sprites that have been imported from a skeletal animation file (like the JSON files that Spine exports) and can be used to get information about an animation asset in your game, as well as for setting certain properties within an animation. These functions can to be used along with the regular sprite functions and variables, permitting you to (for example) mix two skeleton animations using these special functions while setting the image scale using the normal sprite instance variables. For more information on the sprite instance variables see the section on Instance Variables.

The functions available are:

1. skeleton_animation_get
2. skeleton_animation_set
3. skeleton_animation_get_ext
4. skeleton_animation_set_ext
5. skeleton_animation_get_duration
6. skeleton_animation_mix
7. skeleton_animation_list
8. skeleton_animation_clear
9. skeleton_animation_get_frames
10. skeleton_animation_get_frame
11. skeleton_animation_set_frame
12. skeleton_get_minmax
13. skeleton_get_num_bounds
14. skeleton_get_bounds
15. skeleton_skin_get
16. skeleton_skin_set
17. skeleton_skin_list
18. skeleton_attachment_get
19. skeleton_attachment_set
20. skeleton_attachment_create
21. skeleton_bone_data_get
22. skeleton_bone_data_set
23. skeleton_bone_state_get
24. skeleton_bone_state_set
25. skeleton_slot_data
26. skeleton_collision_draw_set

You can also use various draw routines designed specifically for these types of sprite (apart from the regular draw_sprite() functions). These functions give you more control over what is being drawn and permit you to change animation specific features, such as timing and skins:

1. draw_skeleton
   
2. draw_skeleton_collision
   
3. draw_skeleton_time
