Xpresso

XPRESSO is the old node-based system to create custom expressions. This is not the nodal system for Cinema 4D Node Material.

Classic API:

  • c4d.XpressoTag: Stores a node system and returns the GvNodeMaster.
  • c4d.modules.graphview.GvNodeMaster: Stores a collection of GvNode, gives access to the stored nodes and is used to create new nodes.
  • c4d.modules.graphview.GvNode: Represents a single node.
  • c4d.modules.graphview.GvPort: Represents a single port of a node. Connection between GvNode, are done through GvPort.

Examples

gvnode_delete

Deletes the first node created from the Xpresso Tag of the selected object.

gvnode_move

Moves the first node in the Graph View created from the Xpresso Tag of the selected object.

gvnodemaster_creates_connects_nodes

Creates a Constants and Results node in the Xpresso Tag of the selected object.
Connects both Nodes together.

gvnodemaster_from_xpresso_tag

Retrieves the Node Master (The BaseList2D object that holds all nodes) from an Xpresso Tag.

gvnodemaster_loops_nodes

Loops through all nodes from the Xpresso Tag of the selected object.
Checks if it's a Constant Node.
