 The applicable press point is chosen from, in order:
 
 1. If the binding lists one or more [Press](xref:UnityEngine.InputSystem.Interactions.PressInteraction) interactions, the `pressPoint` from the first `Press` interaction in list order whose `pressPoint` is greater than zero (any interactions before this that are either not `Press`, or `Press` with the default `pressPoint` of zero, are skipped) so action-level press APIs stay aligned with the interaction.

Otherwise, the driving [ButtonControl](xref:UnityEngine.InputSystem.Controls.ButtonControl), [Vector2Control](xref:UnityEngine.InputSystem.Controls.Vector2Control), or [StickControl](xref:UnityEngine.InputSystem.Controls.StickControl) [`pressPointOrDefault`](xref:UnityEngine.InputSystem.Controls.ButtonControl.pressPointOrDefault).

Otherwise (for example the action is driven by a [Vector2Control](xref:UnityEngine.InputSystem.Controls.Vector2Control) or [StickControl](xref:UnityEngine.InputSystem.Controls.StickControl) magnitude), [defaultButtonPressPoint](xref:UnityEngine.InputSystem.InputSettings.defaultButtonPressPoint).
 
 On [composites](xref:input-system-action-bindings#composite-bindings), interaction parameters are taken from the composite binding.

+[`InputControl.IsPressed`](xref:UnityEngine.InputSystem.InputControlExtensions.IsPressed) does not consider binding interactions. If you do not pass a custom threshold, it uses [`pressPointOrDefault`](xref:UnityEngine.InputSystem.Controls.ButtonControl.pressPointOrDefault) when the control is a [`ButtonControl`](xref:UnityEngine.InputSystem.Controls.ButtonControl), and otherwise compares actuation magnitude to [defaultButtonPressPoint](xref:UnityEngine.InputSystem.InputSettings.defaultButtonPressPoint) (including for [`Vector2Control`](xref:UnityEngine.InputSystem.Controls.Vector2Control) and [`StickControl`](xref:UnityEngine.InputSystem.Controls.StickControl)).
 
 This example uses three actions called Shield, Teleport and Submit (which are not included in the [default actions](xref:project-wide-actions#the-default-actions)):
