change color of ui in update

hi all!

I need to change a text color in the update function...
what's the better way to do this?
(impacting less time?)

this?

Code (CSharp):

1. if (ChronoSec < ChronoStop)
2. {
3.     if (UiTimer.color != Color.red)
4.     {
5.         UiTimer.color = Color.red;
6.     }
7. }

or this?

Code (CSharp):

1. if (ChronoSec < ChronoStop)
2. {
3.     UiTimer.color = Color.red;
4. }

 

The second one is more optimized because calling UiTimer.color calls a "property getter" function in the background, and calling "Color.red" is like calling "new Color(1, 0, 0, 1)".

Your first snippet calls a property getter once, property setter once, and "new Color" twice.
By comparison, your second snippet only calls a property setter once, and "new Color" once.


That said, this is a very minor optimization. I would not worry about such little things unless your game is running slow or you are working on a huge AAA game that needs every little performance boosts it can get to achieve top-tier graphic effects.

 

thank you @Gambit-MSplitz

the first snippet comes from a old thing on winforms, where if I set the color each time, it blink...
