CocosCreator使用内置shader做灰图片与骨骼动画

// 获取节点/子节点数组(递归)
function getNodeList(node){
    var list = [node]
    var children = node.getChildren()
    for(var i = 0 ; i < children.length ; i++)
    {
        var rtn = getNodeList(children[i])
        Array.prototype.push.apply(list , rtn)
    }
    return list
}
// 递归设置/还原node及子节点灰色
function setGray(node , bGray){
    var list = getNodeList(node)
    var program = bGray ? cc.Scale9Sprite.WebGLRenderCmd._getGrayShaderProgram() : cc.shaderCache.programForKey(cc.macro.SHADER_SPRITE_POSITION_TEXTURECOLOR)
    for(var i = 0 ; i < list.length ; i++)
    {
        var sprite = list[i].getComponent(cc.Sprite)
        var display = list[i].getComponent(dragonBones.ArmatureDisplay)
        // sprite
        if(sprite) sprite._sgNode.setState(bGray ? cc.Scale9Sprite.state.GRAY : cc.Scale9Sprite.state.NORMAL)
        // dragonBones
        if( display && display._sgNode )
        {
            var children = display._sgNode.getChildren()
            for(var j = 0 ; j < children.length ; j++)
            {
                children[j]._renderCmd._shaderProgram = program
            }
        }
    }
}
