It may be that the game designer has set the alpha value of a GameObject in the Inspector window to the initial value they want. So, let's enhance our code to allow this to be indicated by checking a public Boolean flag variable in the Inspector window and adding code to read and use the GameObject's alpha if that option is chosen.

1. In the Inspector window, click Color picker for the Albedo material and set the Alpha value to something other than 255 (for example, set it to 32, which is almost transparent):

2. Add a new public Boolean variable to our script (default to false):

public bool useMaterialAlpha = false; 

3. Add logic to the Start() method so that if this flag is true, we use the Alpha value of the color that was read from...
