## Parameters

### Index

Parameter ID: `GV_LINK_OPERATOR_INDEX` · Range: [-2147483648..2147483647]

This port enables you to access a particular object from the list. For example, pass a value of 0 to this port to access the first object in the list, a value of 1 to access the second object in the list, and so on. If the Index value is greater than the number of objects in the list, the index loops back to the start of the list again. So if, for example, there are two objects in the list and the Index value is 2, the node will output the first object (0 = first object, 1 = second object, 2 = first object again, and so on).

### Link

Parameter ID: `GV_LINK_OUTPUT`

Outputs the index number of the object selected in the Link List.

### Count

Parameter ID: `GV_LINK_OUTPUT_COUNT` · Range: [-2147483648..2147483647]

Outputs the total number of objects in the Link List.
