In-Depth Information
Underneath the
Update()
function, add the
NewColor()
function:
function NewColor() {
red = RandomColorValue();
green = RandomColorValue();
blue = RandomColorValue();
alpha = RandomColorValue();
gameObject.renderer.material.color = Color(red, green, blue, alpha);
waitTime = 5;
}
Now instead of using this code block twice, you can replace it in the
Start()
and
Update()
functions
with a call to
NewColor()
:
function Start()
{
// On Start, set a random color for the sphere material.
NewColor();
// Print the random color values to the Console.
print(gameObject.renderer.material.color);
}
function Update()
{
waitTime -= Time.deltaTime;
if (waitTime < 0.0f) {
gameObject.renderer.material.color = Color.blue;
}
if(Input.GetKey(KeyCode.N)) {
NewColor();
}
}
Your
Start()
function is cleaner and easier to read and so is your
Update()
function. If you find you
would like to change the sphere color during some other process you add in the future, you can do it
with the single line of code,
NewColor();
.
Cleaning up your code by rewriting portions of it is known as
refactoring
. Refactoring as a project
progresses in order to keep the scripts clean and simple is an excellent habit to develop and
ultimately makes life easier for you.
