Perception Trigger Devices

With the Perception Trigger, you can drive gameplay using line of sight between the device and players. When conditions related to line-of-sight checks are satisfied, the Perception Trigger transmits a signal through a channel to activate other devices.

Device Options

In its default state, the Perception Trigger does nothing. You must use event binding for this device to be effective. You can configure the device to trigger only for certain classes or teams, to trigger a limited number of times, and you can add a trigger delay and a reset delay. You can also configure the device to display a visual effect or play a sound when triggered.

You can configure this device with the following options.

Direct Event Binding

Direct event binding allows devices to communicate directly, which makes your workflow more intuitive, and gives you more freedom to focus on your design ideas. With this system, devices communicate directly with other devices.

Below are the functions and events for this device.

Functions

A function listens for an event on a device then performs an action.

1. For any function, click the option, then Select Device to access and select from the Device dropdown menu.

2. Once you've selected a device, click Select Event to bind the device to an event that will trigger the function.

3. If more than one device or event triggers a function, click the Add button to add a line and repeat these steps.

Events

An event tells another device when to perform a function.

1. For any event, click the option, then Select Device to access and select from the Device dropdown menu.

2. Once you've selected a device, click Select Function to bind this event to a function for that device.

3. If more than one function is triggered by the event, click the Add button to add a line and repeat these steps.

Design Examples

Here are some examples of how you can use the Perception Trigger device.

• Hide and Seek

• Moving Target

Hide and Seek

Create a hide-and-seek game using the Perception Trigger as the seeker. To make the game more interesting, turn the Perception Trigger on and off every 5 seconds to give the player opportunities to move around the room.

Devices used:

• 1 x Perception Trigger

• 1 x Damage Volume

• 1 x HUD Message

• 2 x Timed Objective

1. Create a simple hide-and-seek area with different obstacles to block the seeker’s sightline.

2. Place a Damage Volume in the center of the play area and customize it to the following settings:

   

   Option	Value	Description
   Zone Width	7	The Damage Volume will be 7 tiles wide. Adjust this setting so the Damage Volume encompasses the entire area of the game.
   Zone Depth	3	The Damage Volume will be 3 tiles deep. Adjust this setting so that the Damage Volume encompasses the entire area of the Hide and Seek game.
   Damage Type	Elimination	If a player is inside of the Damage Volume, they will be immediately eliminated.
   Enabled During Phase	None	The Damage Volume will begin disabled.

3. Place a HUD Message outside of the play area and customize it to the following settings:

   

   Option	Value	Description
   Message	You’ve Been Spotted!	This message will show when the player is spotted by the Perception Trigger.
   Time From Round Start	Off	The message will not be shown automatically after the round starts.

4. Place a large Perception Trigger toward one end of the play area and customize it to the following settings:

   

   Option	Value	Description
   Enabled on Game Start	Disabled	The Perception Trigger will be disabled when the game starts.

5. Set the direct event bindings of the Perception Trigger to the following:

   

   Function	Device	Event	Description
   On Device Sees A Player Send Event To	DamageVolume	Enable	When the player is spotted, the Damage Volume will turn on, eliminating them.
   On Device Sees A Player Send Event To	SeenHUDMessage	Show	When the player is spotted, they will be shown a HUD Message telling them that they were spotted.

6. To create the effect of the eye turning on and off every 5 seconds, you will use two Timed Objectives. Place a Timed Objective outside of the play area. This will be the device that enables the Perception Trigger, so give it a clear name. Customize it to the following settings:

   

   Option	Value	Description
   Start When Round Starts	Yes	The Timed Objective will begin counting when the round starts.
   Time	5 Seconds	The Timed Objective will complete after 5 seconds.
   Timer Label Text	The eye will see in…	The HUD will display this label before the countdown.
   Visible During Game	No	The Timed Objective itself will not be visible during gameplay.
   Completion Behavior	Reset	After completing the countdown, the Timed Objective will reset and will be ready to be started again.
   Audio Effects	Off	The Timed Objective will not play any audio effects.

7. Place another Timed Objective outside of the play area. This will be the device that disables the Perception Trigger, so give it a clear name that differentiates it from the other Timed Objective. Customize it to the following settings:

   

   Option	Value	Description
   Time	5 Seconds	The Timed Objective will complete after 5 seconds.
   Timer Label Text	The eye will stop looking in…	The HUD will display this label before the countdown.
   Visible During Game	No	The Timed Objective itself will not be visible during gameplay.
   Completion Behavior	Reset	After completing the countdown, the Timed Objective will reset and will be ready to be started again.
   Audio Effects	Off	The Timed Objective will not play any audio effects.

8. Set the direct event bindings of the first Timed Objective to the following:

   

   Function	Device	Event	Description
   On Completed Send Event To	PerceptionTrigger	Enable when Receiving From	When this Timed Objective completes, it enables the Perception Trigger.
   On Completed Send Event To	StopLookingTimedObjective	Start	When this Timed Objective completes, it starts the countdown on the other Timed Objective.

9. Set the direct event bindings of the second Timed Objective to the following:

   

   Function	Device	Event	Description
   On Completed Send Event To	PerceptionTrigger	Disable when Receiving From	When this Timed Objective completes, it disables the Perception Trigger.
   On Completed Send Event To	StartLookingTimedObjective	Start	When this Timed Objective completes, it starts the countdown on the other Timed Objective.

Here’s an overview of how devices communicate in this example:

You now have the basic functionality for a hide and seek game using the Perception Trigger.

Moving Target

Use the Perception Trigger’s player sightline functionality to change the game based on where the player is looking. In this example, create targets that disappear one second after the player first sees them.

   On Triggered Send Event To	PerceptionTrigger1	Enable when Receiving From	When this Trigger is triggered, the corresponding Perception Trigger will be enabled.

7. Place a Random Number Generator away from the play area and customize it to the following settings:

   Option	Value	Description
   Value Limit 2	3	The Random Number Generator will choose a value between 1 and 3.
   Roll Time	Instant	The Random Number Generator will not have any delay when picking a number.

9. Select the target prop, Prop Manipulator, Perception Trigger, and Trigger, then duplicate them two more times in different areas around the player.

10. Move each of the three Triggers that correspond with the different targets into the three different trigger zone areas of the Random Number Generator.

Here’s an overview of how devices communicate in this example:

You now have the basic functionality for targets that disappear based on when the player looks at them.
