changing alpha of a text

How do i change alpha of text. I am using this but doesnt seem to work

Code (CSharp):

1. public Text healthtext;
2.  
3. healthtext.text = healthpack.ToString();
4.         Color zm = healthtext.color;
5.         zm.a = 0.0f;

 

Well I guess that is not all the code you do to change alpha of text?!
Do you set the color of healthtext to the color you instantiated?
Meaning:

Code (CSharp):

1. healthtext.color = zm;

 

I got one, woot! Good post, good question. Good OP.

So you have the alpha of the material, but you also have the alpha of the Canvas Renderer, which we can think of like a Mesh Renderer but it renders any component on the Canvas it's attached to. Look at a Text object in your hierarchy and you should find one.

Text.CrossFadeAlpha lets you change the alpha of an entire Text object really easily. Try that instead.

Also aside, let me further elaborate:

Code (CSharp):

1. public Text healthtext;
2. healthtext.text = healthpack.ToString();
3.         Color zm = healthtext.color;  //  makes a new color zm
4.         zm.a = 0.0f; // makes the color zm transparent

You'll need to also set the color of the Text's material to zm!

Don't feel bad, I still haven't stopped using the equals sign (or "assignment operator") incorrectly sometimes!

 

Congratulations you saved a life going to the halo!!!
