Instances / Prefabs in Spine

sHAYM4N

Hi, I was just wondering if a prefab instances option could work in Spine?

I've been working on a scene with a few props that need to be identical, run the same animations, but then also have other higher level animations that affect the positioning of these props with constraints etc.

The props being just a series of bones, skeletons not being an option as I need to use constraints with a creature that effectively grabs them

The problem I have is that if I want to add something to one of the props, like a new set of sprites, bones etc. Is that I'd have to change one of the originals, delete the series duplicate the new one and reset up for the animations with constraints which can be pretty time consuming.

Unless I'm missing something or there is a better option, it would be great if there was a feature to prefab a series of bones that could be updated across a set?

Hi, think this topic has been moved to Unity - but I probably didn't explain very well. I don't mean anything connected to Unity prefabs, but more of a prefab instance like system within spine for bone setups?

A Prefab like system for in-editor use has come up quite a few times. While it can indeed be very helpful like in your scenario, it would also require a major rewrite of Spine's internals. We currently have no short to mid-term plans to implement this feature I'm afraid.

Maybe @erikari has an idea for a better workflow using the current feature set?

Hello! When you say that you have many identical props, are you using them in a specific runtime or only inside Spine as multiple separate skeletons inside the same project?

Are you using them only for previewing purposes inside Spine but you'll ultimately export one of them only? This would explain why you're trying to keep them all in sync.

What is the final output that you're planning to create? a video, a game, or something else?

Hi many thanks for the replies, well in this case it's for a slot game - PixiJS.

The bonus round I'm creating has a monster with 3 crates that lower, he grabs them, player selects crates explode etc...

The scene itself is 1 skeleton with a bone rig for the monster & 3 bone setups under the root for the crates. The crates are identical but do twist with mesh deforms using an offset and a swing to make them appear to not be the same setup.

The crates I couldn't have as separate skeletons (as far as I am aware) because I'm using transform constraints to attach and drop them.

To be honest I have only just noticed linked meshes as well which may help in this case too -, but thought it maybe handy to have some sort of setup whereby bones and meshes could be linked as a prefab of sorts (or a smartobject in photoshop would be another good example).

Problem with the workflow has been the mode itself hasn't been fully defined and as I'm working and testing it pretty much ad-hoc so if I change something in crate 1, I'm having to duplicate all the changes for each tweak on each crate, which can take a little time.

It's nothing major right now as I'm pretty close to it being done, but thought it maybe a nice feature to have at some point.
