HI everyone,
I am new to c++ and ran into a few problems, I am tring to add twp string together using.

char* charset[4][17]

char* name // is part of a type

then i go to build the player name.
Player[0].Name = Player[0].Name + CharSet[Y_Letter][X_Letter];

but i get an error that i can't add to pointers. well doing some search on this, i came across some stuff about using std::string so i gave that a try now some function call to darksdk don't work so i guss thats not an option.

STD should work okay.

As I dont use it, the easiest way to add two strings together is to use strcat.

when i use std i get error C2664: 'dbCenterText' : cannot convert parameter 3 from 'std::string' to 'char *'
error C2664: 'dbLen' : cannot convert parameter 1 from 'std::string' to 'char *'

Maybe there is a step i missing.

// in the header file.
typedef struct tPlayer
{
std::string Name;
int MaxHp;
int MaxMp;
int Hp;
int Mp;
int Exp;
int Lv;
int Atk;
int Def;
int Agi;
int Str;
int E_Weap;
int E_Arm;
int E_Shd;
float X;
float Y;
float Z;
int Obj;
} tPlayer;

tPlayer Player[1];
std::string CharSet[4][17];

// in cpp file

dbCenterText ( X_Screen,Y_Screen-1,Player[0].Name );

if ( dbLen ( Player[0].Name ) < 10 )
{
//Limit is 9 char.
Player[0].Name = Player[0].Name + CharSet[Y_Letter][X_Letter];
}

You can use std::string with the DarkSDK ... it's just that you currently have to override some warnings/errors to get it to compile cleanly.



I've asked Mike to change the SDK in the next version to allow 'const char*' for all commands that accept strings instead of 'char *' so that we can avoid this potentially dangerous casting.
