Verse `using` statement	`using { /Fortnite.com/Devices }`

Inheritance Hierarchy

This class is derived from the following hierarchy, starting with creative_object:

Name	Description
`creative_object`	Base class for creative devices and props.
`creative_device_base`	Base class for creative_device.
`trigger_base_device`	Base class for various specialized trigger devices. See also: `trigger_device` `perception_trigger_device` * `attribute_evaluator_device`

Members

This class has both data members and functions.

Data

Data Member Name	Type	Description
`AgentLooksAtDeviceEvent`	`listenable(payload)`	Signaled when an `agent` has direct line of sight to this device. Sends the `agent` that has seen this device.
`AgentLooksAwayFromDeviceEvent`	`listenable(payload)`	Signaled when an `agent` has lost direct line of sight to this device. Sends the `agent` that has lost sight of this device.
`DeviceLosesSightOfAgentEvent`	`listenable(payload)`	Signaled when this device loses direct line of sight to an `agent`. Sends the `agent` this device has lost sight of.
`DeviceSeesAgentEvent`	`listenable(payload)`	Signaled when this device has direct line of sight to an `agent`. Sends the `agent` seen by this device.

Functions

Function Name	Description
`Disable`	Disables this device.
`Enable`	Enables this device.
`GetLookingAtDeviceAgents`	Returns an array of agents that are currently of the class defined by this device.
`GetMaxTriggerCount`	Gets the maximum amount of times this device can trigger. `0` indicates no limit on trigger count.
`GetPerceivedAgents`	Returns an array of agents that are currently of the class defined by this device.
`GetResetDelay`	Gets the time (in seconds) before the device can be triggered again (if `MaxTrigger` count allows).
`GetTransform`	Returns the transform of the `creative_object` with units in cm. You must check `creative_object.IsValid` before calling this if there is a possibility the object has been disposed or destroyed by gameplay. Otherwise a runtime error will result.
`GetTransmitDelay`	Gets the time (in seconds) which must pass after triggering, before this device informs other external devices that it has been triggered.
`GetTriggerCountRemaining`	Returns the number of times that this device can still be triggered before hitting `GetMaxTriggerCount`. Returns `0` if `GetMaxTriggerCount` is unlimited.
`IsLookingAtDevice`	Succeeds when `Agent` is registered to this checkpoint.
`IsPerceived`	Succeeds when `Agent` is registered to this checkpoint.
`MoveTo`	Moves the `creative_object` to the specified `Position` and `Rotation` over the specified time, in seconds. If an animation is currently playing on the `creative_object` it will be stopped and put into the `AnimationNotSet` state.
`MoveTo`	Moves the `creative_object` to the specified `Transform` over the specified time, in seconds. If an animation is currently playing on the `creative_object` it will be stopped and put into the `AnimationNotSet` state.
`Reset`	Resets the number of times this device has been activated. This will set `GetTriggerCountRemaining` back to `0`
`SetMaxTriggerCount`	Sets the maximum amount of times this device can trigger. `0` can be used to indicate no limit on trigger count. `MaxCount` is clamped between [0,20].
`SetResetDelay`	Sets the time (in seconds) after triggering, before the device can be triggered again (if `MaxTrigger` count allows).
`SetTransmitDelay`	Sets the time (in seconds) which must pass after triggering, before this device informs other external devices that it has been triggered.
`TeleportTo`	Teleports the `creative_object` to the specified `Position` and `Rotation`.
`TeleportTo`	Teleports the `creative_object` to the specified location defined by `Transform`, also applies rotation and scale accordingly.
