Ports

Ports represent connection points on a node. The color of a port indicates its data type. The shape of the port provides additional information, as described in the following table.

Icon	Appearance	Description
	Outlined circle	An unconnected port of a specific data type.
	Filled circle	An connected port of a specific data type.
	Square	An object port. You can connect any data type to an object port. However, depending on the node, only specific data types will be valid.
	Triangle	A flow port. For more information, see Flows.

For information about how you can create connections between ports, see Connections.

Viewing port values

When you activate play mode in the Unity editor, you can view the value of some output ports. If you move the mouse cursor over the output port, a tooltip indicates the type and value.
