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

<C>

1. include <vpsdk/VP.h>
2. include <stdio.h>
3. include <stdlib.h>

1. define Username "username"
2. define Password "password"
3. define Botname "greeterbot"
4. define Worldname "VP-Gate"

void event_avatar_add(VPInstance sdk);

int main(int argc, char ** argv) {

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

   VPInstance sdk;
   sdk = vp_create();

   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[100];
   sprintf((char*)&message, "Hello, %s!", vp_string(sdk, VP_AVATAR_NAME));
   vp_say(sdk, (char*)&message);

} </C>

C#

In order to use the Virtual Paradise .Net SDK you must:

• Have Visual Studio or Visual C# Express installed and configured
• Download the .Net SDK from the VPNet SDK Download page
• The latest version of the native VP x86 SDK is included in the VPNET distribution
