Adding a Completely New Dimension of Interactivity and Thrill.

How To: Triggers and Buttons

Welcome to our latest tutorial where we’ll dive headfirst into the world of transmitters and receivers in game design. By the end of this lesson, you’ll have conquered the art of creating moving platforms that respond to triggers, adding a whole new dimension of interactivity and thrill to your game levels.

Trigger Examples

Within game design, you can use triggers in multiple ways within your levels. They serve as the logic behind the scenes that can prompt the player to navigate through the level, determining how to progress within your map. Here are some of the different ways you can incorporate triggers into your designs:

  • Devices: Within a scene, the player may need to trigger a device to turn on in order to get information they need in order to understand the world and progress.
  • Mechanics: A layer of complexity can be achieved by using triggers to turn on game mechanics such as jumping platforms.
  • Doors: The most generic use case is using a trigger to open a door that requires a key or other predetermined step in order for the player to progress.

Now that we have some context on how triggers are used within a level, let’s get started and unleash the power of game design!
