An overview of the binocular feature we're going to implement in this module. You'll create an interactive high-tech binocular overlay effect.

We still need to implement the arrow effects, so we position the arrows and tie them to user input so they light up as the player moves around.

We add the zoom functionality to the binoculars, letting the player toggle between several different camera focal lengths. We also adjust the arrows to make them work better.

Here we fully implement the distance readout from earlier. We use a GUI Skin to enhance its look and reposition it on screen.

Here we set up a new scene in which we can test our binocular effect.

Learn how to create a basic distance readout by casting a ray from your camera into your scene, detecting where it hits, and displaying the hit distance using a GUI Text component.

You'll be able to create all the 2D assets you need for the binoculars from scratch in Photoshop. We guide you through that process; feel free to add your own creative touches!

We need to add our new custom graphics to our Unity project before we can use them. The asset importer makes this a simple task.

We make a new script for all our overlay textures so we can more easily control their size and position on screen.

We begin to construct the binocular object by putting the 2D images into GUI Texture components, properly positioning them onscreen, and creating a hierarchy to organize everything.
