Spine 2.1.27 Pro Overlay Mode (Blending)

Update spine to 2.1.27 Pro and find that more overlays are available,

Previously only normal and additive were optional.

More overlay methods are useful for animating special effects with spine. But I haven't tried these stacking methods to create a richer combination like the overlay in Photoshop.

Today, however, the new version of the Spine 2.1.27 Pro made in the use of additive overlay animation to play in Cocos2dx 3.3, found that additive did not take effect.

Through the COCOS2DX 3.3 integrated Spineruntime source code debugging, found in the JSON parsing a step, there is no additive property read in, a look at the original JSON file format is:

Property name: "Additive", Value: TRUE or FALSE.

Now the format of the JSON file becomes:

Property name: "Blending", Value: Normal,additive,multiply,screen.

So with the old version of the Spineruntime parsing, can not find the "Additive" this attribute name, so it is not considered Additive.

The best solution is to update spineruntime. And then everything is OK.
