C/C++

In order to use the Virtual Paradise C SDK you must:

  • Have Visual Studio, Visual C++ Express or another compatible C/C++ IDE+Compiler installed and configured
  • Download the x86 SDK from the Developer Downloads page
#include <VPSDK/VP.h>
#include <stdio.h>
#include <stdlib.h>

#define Username "username"
#define Password "password"
#define Botname  "greeterbot"
#define Worldname "testworld"

void event_avatar_add(VPInstance sdk);

int main(int argc, char ** argv)
{
    int err;
    VPInstance sdk;

    if(err = vp_init(VPSDK_VERSION))
    {
        printf("Couldn't initialize VP API(reason %d)", err);
        return 1;
    }

    sdk = vp_create(NULL);

    if(err = vp_connect_universe(sdk, "universe.virtualparadise.org", 57000))
    {
        printf("Couldn't connect to universe(reason %d)", err);
        return 1;
    }
    
    if(err = vp_login(sdk, Username, Password, Botname))
    {
        printf("Couldn't login(reason %d)", err);
        return 1;
    }
    
    if(err = vp_enter(sdk, Worldname))
    {
        printf("Couldn't enter world(reason %d)", err);
        return 1;
    }
    
    vp_event_set(sdk, VP_EVENT_AVATAR_ADD, event_avatar_add);
    
    vp_state_change(sdk);
    
    while(vp_wait(sdk, 1000) == 0){}
    return 0;
}

void event_avatar_add(VPInstance sdk)
{
    char message[300];
    sprintf((char*)&message, "Hello, %s!", vp_string(sdk, VP_AVATAR_NAME));
    vp_say(sdk, (char*)&message);
}
