Thread: Why does this keep frezzing up when I run it?

Server + One that allows input:

Code:

#include <SDL.h>
#include <socket.cpp>
#include <iostream>
#include <sstream>
SDL_Event event;
SDL_Surface *screen;
ServerSocket server;
void apply_surface( int x, int y, SDL_Surface* source)
{
    //Make a temporary rectangle to hold the offsets
    SDL_Rect offset;
    
    //Give the offsets to the rectangle
    offset.x = x;
    offset.y = y;
    //Blit the surface
    SDL_BlitSurface( source, NULL, screen, &offset );
    
    SDL_Flip(screen);
    
    
}

void clearscreen(){
            SDL_FillRect( screen, &screen->clip_rect, SDL_MapRGB( screen->format, 0x00, 0x00, 0x00 ) );
}













class Dot
{
    private:
    //The X and Y offsets of the dot
    int x, y;



    public:
    //Initializes the variables
    Dot();

    //Takes key presses and adjusts the dot's velocity
    void handle_input();

    //Moves the dot
    void move();

    //Shows the dot on the screen
    void show();
    
    int getx();
    int gety();
};






Dot::Dot()
{
    //Initialize the offsets
    x = 0;
    y = 0;

}



void Dot::handle_input()
{
    //If a key was pressed
    if( event.type == SDL_KEYDOWN )
    {
        //Adjust the velocity
        switch( event.key.keysym.sym )
        {
            case SDLK_UP: y -= 5; break;
            case SDLK_DOWN: y += 5; break;
            case SDLK_LEFT: x -= 5; break;
            case SDLK_RIGHT: x += 5; break;
        }
    }
}

void Dot::show()
{
SDL_Rect basd;
basd.w = 10;
basd.h = 10;

basd.x = x;
SDL_FillRect( screen, &basd, SDL_MapRGB( screen->format, 0x00, 0x99, 0x00 ) );
}
char axw[11];

int Dot::getx(){
    return x;
}
int Dot::gety(){
    return y;
}

int main(int argc, char* args[])
{
    server.StartHosting(4753);
    
        SDL_Init(SDL_INIT_EVERYTHING);
    screen = SDL_SetVideoMode(500,500,32,0);
    clearscreen();
Dot mydot;
Dot hisdot;
bool quit = false;
while(quit == false){
while(SDL_PollEvent(&event)){
if(event.type == SDL_QUIT){
              quit = true;
              }





mydot.handle_input();
clearscreen();
mydot.show();
SDL_Flip(screen);

int xz = mydot.getx();
int yz = mydot.gety();

/*

string hae = az + " BA " + bz;

char *ha;

strcpy(ha,hae.c_str());

server.SendData(ha);
*/

stringstream ooutz;
ooutz << yz;

string az = oout.str();
string bz = ooutz.str();

string zzz = az + " BA " + bz;


memcpy(axw," ",11);

strcpy(axw,zzz.c_str());



}
SDL_Delay(100);
server.SendData(axw);
SDL_Delay(100);
}
}

Client / one that shows what the guy with the server did:

Code:

#include <Socket.h>
#include <SDL.h>
#include <iostream>
#include <sstream>
SDL_Event event;
SDL_Surface *screen;
ClientSocket client;
void apply_surface( int x, int y, SDL_Surface* source)
{
    //Make a temporary rectangle to hold the offsets
    SDL_Rect offset;
    
    //Give the offsets to the rectangle
    offset.x = x;
    offset.y = y;
    //Blit the surface  
    SDL_BlitSurface( source, NULL, screen, &offset );
    
    SDL_Flip(screen);
    
    
}

void clearscreen(){
            SDL_FillRect( screen, &screen->clip_rect, SDL_MapRGB( screen->format, 0x00, 0x00, 0x00 ) );
}













class Dot
{
    private:
    //The X and Y offsets of the dot
    int x, y;



    public:
    //Initializes the variables
    Dot();

    //Takes key presses and adjusts the dot's velocity
    void handle_input(int xx,int yy);

    //Moves the dot
    void move();

    //Shows the dot on the screen
    void show();
    
    int getx();
    int gety();
};






Dot::Dot()
{
    //Initialize the offsets
    x = 0;
    y = 0;

}



void Dot::handle_input(int xx,int yy)
{
y = yy;
x = xx;
}

void Dot::show()
{
SDL_Rect basd;
basd.w = 10;
basd.h = 10;
basd.y = y;
basd.x = x;
SDL_FillRect( screen, &basd, SDL_MapRGB( screen->format, 0x00, 0x99, 0x00 ) );
}


int Dot::getx(){
    return x;
}
int Dot::gety(){
    return y;
}

int main(int argc, char* args[])
{
  
string aaw;
    char coords[11];
   client.ConnectToServer("127.0.0.1",4753);
    
      SDL_Init(SDL_INIT_EVERYTHING);
    screen = SDL_SetVideoMode(500,500,32,0);
    clearscreen();
int zx,zy;
Dot mydot;
Dot hisdot;
bool quit = false;





while(quit == false){
zx = 50;
zy = 50;
for(int p = 1; p<500; p++){


aaw = coords;

if (aaw.size() > 4){

//                100 BA 100

int pos = aaw.find("BA");
string px1 = aaw.substr(0,3);
string px2 = aaw.substr(pos+3,3);              

zx = atoi(px1.c_str());
zy = atoi(px2.c_str());
}

if(zx < 3){
      zx = 150;
      }

if(zy < 3){
      zy = 150;
      }
}
mydot.handle_input(zx,zy);
clearscreen();
mydot.show();
SDL_Flip(screen);



SDL_Delay(100);


client.RecvData(coords,11);

SDL_Delay(100);
}

}

Those are both the programs code.
I belive you saw the sockets.h code.

I might just remake them completly.

Have you tried running in a debugger to see where it's stopping? Or added print statements at least to try to pinpoint?

Also, where's your ClientSocket code?

I do not even know what printf is.
But I can guess...

Does it print down to where the errors show up?



And do I have to download a debugger or is it in my IDE?

I would say that if you can't discover those two on your own, there is little hope of successfully writing a real time client server graphics application.

That dosn't affect me, as I CAN discover that on my own.

Well, your IDE should have a debugger - set a break point early in the code and step through it. That would be preferable to putting print statements everywhere.

I think I got something basic to work!
