Creating a laser aim with Projector and Line Renderer

Although using GUI elements, such as a cross-hair, is a valid way to allow players to aim, replacing (or combining) it with a projected laser dot might be a more interesting approach. In this recipe, we will use the Projector and Line components to implement this concept.

Getting ready

To help us with this recipe, it's been provided with a Unity package containing a sample scene featuring a character holding a laser pointer, and also a texture map named LineTexture.

1. Import BasicScene.unitypackage to a new project. Then, open the scene named BasicScene. This is a basic scene, featuring a player character whose aim is controlled via mouse.

2. Import the Effects package by navigating to the Assets | Import...
