Enhancing the laser aim with a Line Renderer

Let's improve the previous recipe by displaying a laser beam from the character's laser gun to the projected laser target. We'll implement the laser beam through scripting a Line Renderer, which is being redrawn each frame:

 

Getting ready

This recipe ­is based on the previous one, so make a copy of that project and work with its copy. You'll also need a Texture for the beam color; one is provided in the 07_05 folder called beam.psd.

How to do it...

To enhance the laser aim with a Line Renderer, follow these steps:

1. Our Line Renderer will need a Material to work with. Create a new Material named m_beam.
2. In the Inspector, set the Shader of the m_beam to Particles/Additive. Also, set its Tint Color to red (RGB: 255;0;0).
3. Import the beam image file. Then, set it as the ParticleTexture for the m_beam, as follows:

4. Create a new C# script class named LaserBeam, and add an instance object as a component to the Game Object's Laser Projector:

public class LaserBeam...
