Hello,

I`m working on a 2D game and I was wondering if it`s possible to display a parameter on game screen. I need to display bool parameter to see if everything is checking right.

In std c++ it was something like this: cout << x;

Thanks in advance.

Use sprintf to make a formatted string out of your parameters.

http://www.cplusplus.com/reference/clibrary/cstdio/sprintf/

Booleans can be displayed as integers (%d) and will appear as 1 or 0 for true/false, which is quite enough for debug purposes:



Or if you want to get a bit more sophisticated, you can convert it to text:



You can display several parameters in one string.

Well I tried something like this:



And it displayed error message :

error C2664: 'dbText' : cannot convert parameter 3 from 'int' to 'char *'
1> Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast

sprintf(Buffer, "valid is: %d", int(valid));

The fastest code is the code never written.

I am trying to fade my background onto the screen over a duration of 2 seconds. The code I'm using (below) just makes the bitmap instantly appear fully visible, but I fail to see why. Hopefully you guys will know what my problem is.
