So, after hours of hit and trials, here are my OBSERVATIONS when importing spine project in DragonBones.
(1) You cannot import
.atlas file and its sprite sheet from the assets option. It takes only
.xml is general So, if you have multiple
.atlas sprite sheets of spine animation, do it at the time of Creating a new project from spine, otherwise, it won't give option to read
.atlas file later.
(2) Even after importing Spine animation, it didn't put images in respective slots for me and in one case, the scale of some images were not correct. However, it shows the correct name of images in the slot but no sprite was actually present even if the assets are correct available in DragonBones library. The author of dragonbones told that DragonBones doesn't support some features of spine.
(3) If multiple
.atlas files are in the same folder then it picks the first
.atlas file. Ideally, it should pick the one with the same name. So, you have to manually browse the correct file. However, .png, it picks automatically corresponding to the name of
(4) There is some meta in the starting of animation file of spine(you can easily find it). If that meta is not correct or missing then it won't be read by DragonBones. So, if correct file is not working for you, find if that's missing.
(5) Don't use random texture data file, example, don't generate it by script which converts json to atlas, or vice versa, etc. Because that might not always work. DragonBones reads atlas file and converts into correct
.json texture data file which is readable to DragonBones itself. So, you must see that if the texture data finally matches with what is given in the default examples of DragonBones software.
FINALLY, simple steps to import are if your
.png files are correct are:
1) Click on import(not import assets), form the toolbar
2) It opens the popup and asks you to select "Animation" data file which is your spine animation file. When you select that .json animation file, DragonBones automatically selects "Spine Animation Data" in the next window popup.
3) So, now, you just select the corresponding texture
.atlas data and
(In my case it was
png. I am not sure if Spine exports other format as well. So, whatever it exported from spine should work, I guess)
I've given a little pause to animation. So, above steps can look vague to you but assured, they are correct observations.
I Hope some of it is helpful as there is probably nothing out there which could seriously help, AFAIK.
