# Access to parameters

## Create Access Node

You can create access nodes by dragging and dropping parameters into the graph view.

- Drag the parameter's drag area.
- Drop at the position you want to create in the graph view.
- From the menu, select Get or Set.
  (For Set node, execution nodes of various graphs are created. Please connect so that it will be executed after creation.)

## Access by ParameterReference

In scripts with ParameterReference related classes, you can set parameters that handle values.

### Setting by ParameterReference field

- Set ParameterContainer with the parameter you want to refer to.

### Input from data slot

The Container field also supports input from data slots.

- The parameter name to be referred to in the Parameter field is set as a string.
- (Depending on the behaviour, you also need to set the type of Parameter)

For data slots, refer to Data Flow.
