I'm an artist so I don't know really know anything about implementation or coding. I just wanna ask how do I set up equipment slots in the Spine program so when I export it to Unity , the devs can use it to call/change equipments for the character ?

There's project files for AtlasRegionAttacher ( the FootSoldier one ) for Unity , but there's no FootSoldier example project file for Spine

Please consider the Goblins example Spine project and example scene (Spine Examples/Other Examples/Goblins in the Spine-Unity package) as a more up-to-date reference on skins, slots and attachments.

There is also a tutorial video:
Spine Tutorial - Skin Workflow - YouTube

Thank you for the answer . But I cannot find the appropriate script in the examples in Unity . I'm trying to do a character exactly like the zombie in PvZ . One basic version and an upgraded version with an object on top, with an animation of it falling off

For example , in the goblin example files , I would like goblin to have attach/detachable shield and spear that can be turned on and off , an I missing a script in the example file that does this ?
