Incrementation of variable

I always used programming languages such as C++ or Java. I decided to put some effort to share my experiences with EV3 software... which are not so good.
I spent about an hour to findout how increment variable, even tried to use Google to find solution. In C++ you can just use someting like this:
  int var = 0;
  var++;
and that's it. Here you need to use variable block twice (for read and write) and block which adds 1 to this variable.
Anyway.... here is what I did and it works:

Here is link to project, which will play simple music.

Shooting robot (EV3RSTORM)

I was a little disappointed when I opened a box, and in box there was instruction to build TRACK3R. Hm.... I expected to have R3PTAR (snake) or EV3RSTORM (robot). They are everywhere on internet.
Anyway,  instead of build TRACK3R (which is included in box) I decided to be more fancy and build EV3RSTORM.

First problem: it is not so easy to find online instruction. Finally I downloaded EV3 software from Lego site, and there are links...

Long story short: It takes me around 2 hours to create robot, and create simple program - robot will shoot if you cover his eyes!

See pics, and video below.

Yay!
Finally I decided to buy new Lego Mindstorms set!
After few days of waiting..... it's ready for explore :)
