I'd added a simple animationskeleton and it loads ok at design time, but when I run the editor, it just disapears. Do i need to turn anything on or something?

@dirsow Sorry to hear you're having troubles. No, there is nothing you need to do, it should just display normally.

Does it really disappear when you hit play, or is it perhaps also not visible before hitting the play button? In other words, do you see the correct skeleton in the Game view before hitting play? It looks like your skeleton is just way off camera, being at X position 1166.

@dirsow This might happen when you edit your Canvas UI elements, which are at location e.g. 0 - 1920 units (100 times larger in editor scale, since with Canvas 1 unit = 1 px) while your normal MeshRenderer GameObjects are typically positioned in metric units of e.g. 0-10 units.

    That’s my first 2d game. I was working with sprites and it may have an undesirable behavior with game objects. I’ll try 0,0,0 and see if it’s just a offscreen simple issue.
    Thanks for your attention

    Harald That was indeed the issue. I'm so sorry. Thank you so much for your help

    @dirsow Unity Sprites are also placed like normal MeshRenderers, as opposed to UI Canvas elements/images which live in the separate "larger" Canvas space described above.

    In general it's highly recommended to get familiar with the basics of Unity before attempting more complicated things like using Spine skeletons. Also you might want to separate your Scene view and Game view panels so that you can see what your camera is actually viewing, don't just try modifying values.
