GameBlade - 2D Game API using SDL (C++)

Hey,

I found SDL way too complicated for what i wanted to do for an RPG. Gameblade makes it a lot easier to put graphics into my game.
What i was wondering, after trying to make an RPG with the gameblade, is how you would display a variable to screen. The text engine included only expects characters...

I can see that you used something in SpaceBlade:
sprintf( String, "E %d/%d ", Ship->GetHPNow(), Ship->GetHPMax() );
GB_DrawText( &String[0], x+80, y+24 );

Could you explain that to me? I'm a bit of a c/c++ newbie :P
