Node: Static and dynamic output type for extended nodes

[sunag]

Description

Now NodeMaterial support static and dynamic generate output type for extended nodes, therefore is not more necessary to convert all generate snippet for a different output in an extended Node, it simplifies the code for creation of futures Nodes besides being backwards compatibly.

How a simple code design change can make a difference: Only here, we reduce more than 100 lines of code...

Usage

Static

Allow that Node class convert the default snippet generated for the requested output.

class ExtendedNode extends Node{

	// static generate ( static output format )

	generate( builder ) {

		// code...

	}

}

Dynamic

Allow that the Node find the better snippet for the requested output.

class ExtendedNode extends Node{

	// dynamic generate ( dynamic output format )

	generate( builder, output ) {

		// code...

	}

}
