| [IVariable](/engine/6000.7/script-reference/unity/graphtoolkit/editor/ivariable.md) | The [IVariable](/engine/6000.7/script-reference/unity/graphtoolkit/editor/ivariable.md) at the specified index. |

### Remarks

Use this method to access a specific [IVariable](/engine/6000.7/script-reference/unity/graphtoolkit/editor/ivariable.md) from the list of variables declared in the graph. This list does not include variable nodes that reference variables. The index is zero-based and reflects the order in which the variables were created. The index must be within the valid range of the variable list (see: [Graph.VariableCount](/engine/6000.7/script-reference/unity/graphtoolkit/editor/graph/variablecount.md)).
