Mike at BrashMonkey

Here is the reply from Edgar in another thread that I gleaned this information from earlier:

" As Mike said I'm still working on Spriter 2 stuff at the moment, but I was able to take a look at this issue, finally.
I filed a bug as per Ashley 's suggestion, and it should be simple to update the plugin once the SDK supports animations.
I made an attempt to circumvent the issue using images instead of animations under the hood, and it doesn't seem like there'll be an easy way to do it without breaking projects and redoing a lot of work on the plugin.
Thanks for your patience again everyone. "

Here is the thread it came from: https://brashmonkey.com/forum/index.php?/topic/5086-using-spriter-animation-in-construct-3/&tab=comments#comment-25185
 

I think until the Construct3 SDK is updated to allow us to finish the port of the Spriter plugin to C3, there's nothing we can do about that. A request has been sent recently to Ashley at Scirra, so hopefully it won't be a very longf wait. 
Until then It might be best to continue to use C2 for any on-going project that already uses Spriter for now.
Sorry for the inconvenience.
 

scml is actually XML
Scon is Json
How old was the project? It could have been so old that Spriter updated its data format since then (I think that was several years ago)
Regarding Spriter on Mac, I assume that's because we didn't bother "registering" Spriter with Apple so it's not granted  such niceties as programs that jump through the hoops to register with Apple. But that's just a guess.  Hopefully you can drag an scml or scon onto the Spriter icon and that will work.

Please try downloading the free non-Steam version of Spriter from here and install it and tell me if it runs for you: https://brashmonkey.com/download_spriter/

I recommend you zip up your Spriter project and send it to mail@brashmonkey.com so we can take a look at it. Ideally, a screen recording showing the initial key-frame before it gets "corrupted", then you making changes to a later key-frame, and then the resulting change to the initial key-frame.

Is there a key frame for the things that are getting changed in the first place (there usually is) or are they missing? Do you know how to expand the timeline window to expose the key frames for each specific object?

It certainly sounds like something got somehow corrupted or mass duplicated but that's just a guess.

Can you try comparing the original packs like count for data and the character map and see if it's drastically different?

Which OS are you on?

Are you using something like Dropbox so you have "version control" and can revert back to older versions? (this is critical for production work so you don't lose tons of time/work due to situations like this)

If you'd like, you can email your Spriter project (zip up the entire folder with scml and all images etc) to mail@brashmonkey.com and we'll take a look when we get the chance.

Try loading the one that works and save it in whatever format you like. to be supe safe, save in both and consider the other a backup, but no one else has reported a file looking different after loading for years.

There's a new updte for the C3 Spriter plug-in. Please see if this helps:
 

Hi Everyone,
Here's a new video demonstrating the first Pro-only features to make it into Spriter B2. Namely IK, IK locking, and Rotation/Scale Inheritance toggling for child sprites or bones.

cheers,
Mike at BrashMonkey

That is great... I'll get onto it as soon as possible.
 
Thanks

Looks cool. Nice and clean. Best of luck with it!

I've just launched a free web/Android app, a "point and click" adventure called "Drained." It features quite a few characters and without Spriter I'd still be drawing frames by hand. It is undoubtedly one of the best purchases I've ever made.

Sorry for the delay. Edgar is currently tied up with work on Spriter 2 until we can release the next bit of update info for it. We'll be setting up a C3 subscription shortly for testing and development once Edgar's hands aren't so full. Hopefully it won't be too much longer.
Thanks as always for your patience and support.

I just checked and verified that at the moment collision rectangles are not supported in the C3 Spriter plug-in. It's a high priority to get that fixed, but we can't promise exactly how soon that will happen. 
I'll report back here as soon as there's a fix or progress towards one.

Sorry for the inconvenience.

If you own C2 you might want to keep your project in c@ until we can updated the C3 plugin. That's what I'll be doing with my current couple of projects.

It`s because your attached sprite scale XY axes need to match the bone XY scale axes orientation in order for their scaling to work properly. Bone "length" is the bone ScaleX axis.

The problem is that your character is not setup correctly for use with bones. You can try to rotate your character body image +90 (or -90) degrees in your image editing program (so it looks like it is lying on its side), then go back to spriter, adjust the rotation and it should scale properly.

s. We'll make an announcement when the time comes and everyone who owns Spriter Pro now, or who purchases Sprtier Pro or pre-orders Spriter 2 before the end of the current pre-order sale (Aug 3rd) will be eligible to sign up to be a tester.
Everyone who does will have to agree to an NDA (non-disclosure agreement) to do so.

I just want to close this, as fixed. Thanks.

I would also like to inform that the C3 SDK has some interesting features that you might like to use. Those include,
Editor :: Preview. Draw and Preview plugins on the editor. Potentially can be useful for showing and previewing the initial animation/frame of the Spriter Plugin even while on the editor. Custom Importer :: Drag files to import into Construct 3 and make events, objects, instances, container and families automatically like on Construct 2. Drawing :: The C3 SDK already had drawing features available on the  initial release. So, by now, it is stable enough to be supported. And a few already made use of it. There are probably a lot more. But I recommend you guys checking it out yourselves.
 
Thank you in advance.
