Set the Alpha level of this Game Object. The alpha controls the opacity of the Game Object as it renders. Alpha values are provided as a float between 0, fully transparent, and 1, fully opaque.
If your game is running under WebGL you can optionally specify four different alpha values, each of which
correspond to the four corners of the Game Object. Under Canvas only the topLeft value given is used.
