50-Shield Strength Implementation

In this post, the shield strength will be implemented:

• Visualize the strength of the shield through color changing of the
  shield.
• Allow for 3 hits on the shield to accommodate visualization

The above requirement can be translated into the following actions:

• Assign a strength value to the shield
• Get a handle to the ShieldVisualizer renderer and adjust its color according to the strength value (using Switch statement). To change color, we can use “gameObject.renderer.material.color = Color.red” or similar.
