# Wait
A detailed explanation of controls and interface functions is described in the section [State Machine Builder User Interface](https://docs.google.com/document/d/1-o5qSv4zTkzj7YSmRTkV4zezFq7lwU00FyTy0kw1l1U/edit#bookmark=id.6vu41emx3478).
1. Within the edit Simulation section of the HyperSkill Desktop application, navigate to the State Machine tab.
2. Click on the desired state and from the dropdown in either the entry or exit actions select the type Wait.
3. Press the + button to add the state to the action list.
4. The duration functions as a delay before any actions after it in the state machine will take place. This is particularly useful if you start an animation in a previous state and want to delay feedback until the completion of the animation.
Authors have the option to
1. Enter a fixed duration (s)
2. Dynamic Duration: Link a Virtual Object's custom attribute (integer or float type) to control the wait time. Fixed duration is disabled when this option is active.
Parameters:
1. Entity Type: None (Fixed Duration), Virtual Object
2. Entity: The Virtual Object you want to choose
3. Attribute: Custom attribute atached to the Virtual Object selected (must be a float or integer)
4. Duration: Direct time input (when using fixed duration)
