A node represents an operation in
InstantTerra, i.e. the generation of a terrain using a noise or
even an erosion simulation.
These nodes and their parameters are accessible directly via the API.
// Create an instance of InstantTerra
InstantTerra instantTerra = new InstantTerra();
// Get the current graph and the list of nodes
Graph graph = instantTerra.GetProject().GetGraph();
List<Node> listOfNodes = graph.GetAllNodes();
// Get the first node of the graph
Node myNode = listOfNodes[0];
myNode.SetName("New name");
Console.WriteLine(myNode.GetName());
To change or retrieve a node name, use the methods SetName(name) and GetName.
myNode.SetComment("New comment");
Console.WriteLine(myNode.GetComment());
To change or retrieve a node comment, use the methods SetComment(comment) and GetComment.
Console.WriteLine(myNode.GetNodeType());
To retrieve the node type, use the method GetNodeType.
// Returns the list of node parameters
string[] parameterList = myNode.GetParameterList();
parameterList.ForEach(Console.WriteLine);
The method GetParameterList() returns the list of node
parameters.
// Returns true if the parameter exists
Console.WriteLine(myNode.HasParameter("ParameterName"));
See HasParameter(parameterName) in the
documentation.
// Get the value of the parameter
Console.WriteLine(myNode.GetParameterValue("offset_x"));
// Set the value of the parameter
myNode.SetParameterValue("offset_x", "1.0");
See GetParameterValue(parameterName) and
SetParameterValue(parameterName, value).
Note
If the parameter name does not exist or if the set value is not valid, C# returns an error message with the description of the problem.
