The cocos2d-x provides two macros for the cclayer subclass to generate the cclayer Node Method.

# The Node Method generated by the macro define layer_node_func (layer) does not contain parameters. The subclass must have an Init () method without parameters.

# Define layer_node_func_param (layer ,__ paramtype __,__ Param _) the macro-generated node method has parameters. The subclass must have an init method with the same parameters.
