Transparecy and layers

[dsdevil]

Hello guys!
Yesterday i made my first little demo with sfml i  was incredebly happy!
Now i have some problems.
1. How to make some color transparent?
2. How can i make so that some sprites are behind and in front of other. For example, if i add bacground, i would like it to be behind all other objects. Can i do that?

1. How to make some color transparent?

The alpha (fourth) component of colors is the transparency.

2. How can i make so that some sprites are behind and in front of other. For example, if i add bacground, i would like it to be behind all other objects. Can i do that?

Draw first your background, and then the rest. Simple

Wow, the second i really simple
But with this alpha thing in first, do i have to do it in my picture editor or in code somehow?

You can do it either way or even both if you want too. Check out Sprite::SetColor function.
