I am trying to convert the example in the code bank for formatting text to stay in a box so far i have this. what happens is it cuts some letters off that it shouldn't. can anyone see what i am doing wrong
.h file
class cChatSystem
{
public:
void Chat(std::string sbuffer);
cChatSystem* GetPtr() {return this;}
private:
void DrawChat(); // Chat box will have a default position and size.
void FormatText(std::string text, int width);
std::string CleanText(std::string text);
std::string ls_line;
std::string ls_message;
int lc;
int newx,newy;
int limit;
int chars;
std::string restMsg;
std::string line;
int rest;
int fontheight;
int font_width;
};
cpp file
void cChatSystem::Chat(std::string sbuffer)
{
// create chat box, display text, check for more text, dsplay more icon.
DrawChat(); //Draw the box arounf the text.
fontheight = 0;
font_width = 0;
// Format text for writing.
FormatText(sbuffer, 450);
}
