I am not clear about how to parse regionSequence, could you post an example?

I see document says:

color: The color of the slot for the setup pose. This is an 8 character string containing 4 two digit hex numbers in RGBA order. Assume “FFFFFFFF” if omitted.

But I think the order in skeleton example json is argb, not rgba. Am I right?

That's fine, I will change that when 1.0.9 released. So there is 11 days to release 1.0.9? I am waiting my license.

I finished Spine support in WiEngine: https://github.com/stubma/WiEngine. Maybe something need to be polished or changed when final documentation is out, but the example json works like a magic. View the demo in WiEngineDemos_native/Node/Spine.

When you guys release Spine, please add WiEngine to supported engine list, thanks!

I am adding Spine support and almost done. However, here is an interpolation problem and I need some advice.

I use example-animation.json for my demo, and here is animation definition for "right shoulder" bone:

	"right shoulder": {
		"rotate": {
			"0": {
				"angle": "20.89",
				"curve": [ "0.264", "0", "0.75", "1" ]
			},
			"0.1333": {
				"angle": "3.72",
				"curve": [ "0.272", "0", "0.841", "1" ]
			},
			"0.6666": { "angle": "-278.28" },
			"1.0666": { "angle": "20.89" }
		},
		"translate": {
			"0": { "x": "-7.84", "y": "7.19" },
			"0.1333": { "x": "-6.36", "y": "6.42" },
			"0.6666": { "x": "-11.07", "y": "5.25" },
			"1.0666": { "x": "-7.84", "y": "7.19" }
		}
	},

focus on the third rotate key frame: "0.6666": { "angle": "-278.28" }, its value is -278.28, previous key value is 3.72, so I interpolate between 3.72 and -278.28. However, the result is not correct, if I change -278.28 to 81.72(just add 360), everything goes ok. I understand -278.28 is same as 81.72, but it affects the interpolation. How do I know which value should be used?

I am adding Spine support for my engine(https://github.com/stubma/WiEngine), and also I am a backer of Spine. Spine is great and I like it.

I found the example json is not very completed, so is there a doc about the json format? Or, is there an example json which contains all keys?
