Author Topic: Alpha value of font for chat box (Read 1862 times)

Hi everyone,

I'm planning to develop a chat box, which should be partially transparent.
I thought that this is a perfect job for alpha-values.
But how can I set the alpha-value which is used to draw the text?
Or is there any other good solution?

You can set the alpha component of the color with sf::Text::SetColor(). Or do you want to make the whole window transparent? This is not possible with SFML.

Thx.
I didn't know, what it does.

1.6

Set the color of the object.

The default color is white.

2.0

Set the global color of the object.

This global color affects the entire object, and modulates (multiplies) its original pixels. The default color is white.

What do I need to do if I want to change alpha to 50% and let everything else untouched?

is it

Code: [Select]


SetColor(Color (255, 255, 255, 128));

?
