monogame

In MonoGame I am using SpriteBatch to draw sprites. I want to create a semi transparent overlay that would 'tint' the sprite with a given color. SpriteBatch.Draw accepts Color parameter that allows to specify the tint, however the alpha channel seems to make the whole sprite transparent (not the tint only). To address the problem i am overlaying my sprites with another white, semitransparent sprite tinted to a given color. It works as expected, but I am not sure if that is the correct (ie. most optimal) approach. Can you suggest better/faster technique?

Does this mean you can have one solution (theoretically) with shared code, and it works on all three platforms (PC, Android, iPhone)? Or do you need to port your game from PC to Android, and… >>> More
