Public Methods

Method Description
AddNode ( Node n, bool generateNewUID = true ) : void
Clone ( int idOffset ) : Graph
GenerateShader ( string shaderName, Action addToProperties, Action addToDefs, StringBuilder>.Action returnFragmentColor ) : string

Generates a shader with customized output.
GenerateShader ( string shaderName, string colorRampParamName ) : string

Generates a shader that outputs a color based on the graph's noise and a color ramp texture.
GenerateShader ( string shaderName, string outputs, float defaultVal ) : string

Generates a shader that outputs this graph's noise in the given channels.
GetNode ( int uid ) : Node

Returns "null" if the given Node uid doesn't exist in this graph.
GetObjectData ( SerializationInfo info, StreamingContext context ) : void
Graph ( ) : System
Graph ( SerializationInfo info, StreamingContext context ) : System
Graph ( string file, bool isGUID = false ) : System

Creates a graph for the given file path/GUID.
InsertShaderCode ( StringBuilder shaderProperties, StringBuilder shaderCGDefines, StringBuilder shaderBody, int idOffset, bool isFirstGraph ) : string

Inserts code for this graph into the given strings, and outputs an expression that evaluates to the output of this graph.
IsValidUID ( int uid ) : bool
Load ( ) : string

Re-loads this graph from its file-path, effectively wiping out any changes to it. Returns an error message, or an empty string if nothing went wrong.
PreProcess ( ) : void

Simplifies this graph by running its nodes through the pre-processing stage. The whole graph will be reduced to its final form (i.e. no "weird" nodes like SubGraphNode).
RemoveNode ( Node n ) : void
Save ( ) : string

Saves this graph to its file-path. Returns an error message, or an empty string if nothing went wrong.
