Connections
You use connections to send values and object references between nodes.
Creating a connection
To connect two nodes, drag from an output port on one node to an input port on another node.
Invalid connections
In most cases, if you attempt to create an invalid connection, it will fail. For example, if you drag from a float output port to a vector3 input port, the connection will fail and disappear.
However, square ports accept any type, and the validity of the connection is not evaluated until after you provide all of the required inputs. For nodes with square input ports, the Unsupported Types message appears if you create an invalid connection.
Removing a connection
To remove a connection, choose one of the following methods:
Right-click a port at either end of the connection, and then select Clear Connections.
Left-click the input port and drag the end of the connection to an empty area of the canvas.
Adding points along a connection path
You can add points along the length of a connection path to provide greater control over its route. For example, you could adjust the route of a connection path so that it isn't hidden behind a node or doesn't overlap another connection path. These changes are for aesthetic reasons only and do not affect the connection.
To add a point to a connection path, click the right mouse button while you drag to create a new connection.
After you create the connection, you can drag each point individually to adjust the path.
