Public Methods

Method	Description
AreFloatsDifferent ( float f1, float f2 ) : bool	Compares two floats like normal, except that if they are both NaN, they are considered to be equal.
Clone ( ) : Node	Generates a new node identical to this one, including the UID, but with no graph owner.
Clone ( Graph newOwner, bool addToOwner, int idOffset ) : Node	Generates a new node identical to this one, including the UID, but with a different graph owner.
EmitCode ( StringBuilder outCode ) : void	Appends the actual shader code that computes the output variable.
EmitDefs ( StringBuilder outCode ) : void	Appends any necessary definitions to the given shader.
EmitProperties ( StringBuilder outCode ) : void	Appends any necessary Shaderlab property definitions to the given shader.
GetInputDefaultValue ( int index ) : float
GetInputName ( int index ) : string
GetObjectData ( SerializationInfo info, StreamingContext context ) : void	Outputs class data to a serializer.
Node ( Rect pos, List inputs, List inputNames, List inputDefaultVals ) : System
Node ( SerializationInfo info, StreamingContext context ) : System
OnAddedToGraph ( ) : void	Called when this node's owner/uid is set.
OnGUI ( int &clickedInput, int isSelected ) : GUIResults	Runs the GUI display window for this node. Returns what happened.
OnGraphLoaded ( ) : void	Called after this node's owner is done loading from a file. This is better than a method with OnDeserializedAttribute because this method is only called after the graph itself is fully loaded.
OnPreProcess ( ) : IEnumerable	Called right before the graph generates a shader. Special nodes can take this opportunity to modify the graph however they want. Returns any new nodes that have been added to the graph.

Protected Methods

Method	Description
CustomGUI ( ) : bool	Child nodes can add custom GUI stuff through this method. Must return whether anything has actually changed.
MakeClone ( ) : Node	Should create the right type of node with the same properties as this one. The base properties of all nodes don't need to be filled in by this method.
Node ( ) : System

Method Details

AreFloatsDifferent() public static method

Compares two floats like normal, except that if they are both NaN, they are considered to be *equal*.

public static AreFloatsDifferent ( float f1, float f2 ) : bool
f1	float
f2	float
return	bool

Clone() public method

Generates a new node identical to this one, including the UID, but with no graph owner.

public Clone ( ) : Node
return	Node

Clone() public method

Generates a new node identical to this one, including the UID, but with a different graph owner.

public Clone ( Graph newOwner, bool addToOwner, int idOffset ) : Node
newOwner	Graph
addToOwner	bool
idOffset	int
return	Node

CustomGUI() protected method

Child nodes can add custom GUI stuff through this method. Must return whether anything has actually changed.

protected CustomGUI ( ) : bool
return	bool

EmitCode() public method

Appends the actual shader code that computes the output variable.

public EmitCode ( StringBuilder outCode ) : void
outCode	StringBuilder
return	void

EmitDefs() public method

Appends any necessary definitions to the given shader.

public EmitDefs ( StringBuilder outCode ) : void
outCode	StringBuilder
return	void

EmitProperties() public method

Appends any necessary Shaderlab property definitions to the given shader.

public EmitProperties ( StringBuilder outCode ) : void
outCode	StringBuilder
return	void

GetInputDefaultValue() public method

public GetInputDefaultValue ( int index ) : float
index	int
return	float

GetInputName() public method

public GetInputName ( int index ) : string
index	int
return	string

GetObjectData() public method

Outputs class data to a serializer.

public GetObjectData ( SerializationInfo info, StreamingContext context ) : void
info	System.Runtime.Serialization.SerializationInfo
context	System.Runtime.Serialization.StreamingContext
return	void

MakeClone() protected abstract method

Should create the right type of node with the same properties as this one. The base properties of all nodes don't need to be filled in by this method.

protected abstract MakeClone ( ) : Node
return	Node

Node() protected method

protected Node ( ) : System
return	System

Node() public method

public Node ( Rect pos, List inputs, List inputNames, List inputDefaultVals ) : System
pos	UnityEngine.Rect
inputs	List
inputNames	List
inputDefaultVals	List
return	System

Node() public method

public Node ( SerializationInfo info, StreamingContext context ) : System
info	System.Runtime.Serialization.SerializationInfo
context	System.Runtime.Serialization.StreamingContext
return	System

OnAddedToGraph() public method

Called when this node's owner/uid is set.

public OnAddedToGraph ( ) : void
return	void

OnGUI() public method

Runs the GUI display window for this node. Returns what happened.

public OnGUI ( int &clickedInput, int isSelected ) : GUIResults
clickedInput	int	/// If the user clicked an input, /// the index of that input will be stored in this variable. ///
isSelected	int	/// If this node's output was previously selected, pass -1. /// If an input was selected, pass the index of that input. /// Otherwise, pass anything else. ///
return	GUIResults

OnGraphLoaded() public method

Called after this node's owner is done loading from a file. This is better than a method with OnDeserializedAttribute because this method is only called *after* the graph itself is fully loaded.

public OnGraphLoaded ( ) : void
return	void

OnPreProcess() public method

Called right before the graph generates a shader. Special nodes can take this opportunity to modify the graph however they want. Returns any new nodes that have been added to the graph.

public OnPreProcess ( ) : IEnumerable
return	IEnumerable
