Platform 1.39 Reference Guide

How do I use the Oculus Platform?

The only header you need to include directly is OVR_Platform.h, as it includes all other Platform SDK headers.
See here for a list of all headers.

  1. Initialize :
    See OVR_Platform.h for initialization functions.
  2. Request:
    Make some requests! See below for a full list of requests.
  3. Handle Responses:
    Retrieve responses from the message queue and process them.

#include "OVR_Platform.h"

#include <stdio.h>

int main() {
  // initialize the platform SDK
  ovrPlatformInitializeResult initializeResult = ovr_PlatformInitializeWindows("PUT_YOUR_APP_ID_HERE");

  // quit if initialization failed
  if (initializeResult < 0) {
    puts("Initialization failed");
    return 1;
  }

  // get the logged in user's id
  // this is not a request, so it returns the data directly
  ovrID loggedInUserID = ovr_GetLoggedInUserID();
  if (loggedInUserID == 0) {
    puts("No logged in user");
    return 1;
  }

  // initiate a request to get the logged in users's information
  // this is a request, so the response is returned on the message queue
  ovr_User_Get(loggedInUserID);

  // main loop
  for (;;) {

    // pop messages off of the message queue until it is empty
    for(;;) {
      ovrMessageHandle message = ovr_PopMessage();
      if (message == NULL) {
        break;
      }

      // first check for errors
      if (ovr_Message_IsError(message)) {
        ovrErrorHandle error = ovr_Message_GetError(message);
        puts("Got an error");
        puts(ovr_Error_GetMessage(error));
        return 1;
      }

      // get the message type
      ovrMessageType messageType = ovr_Message_GetType(message);

      // handle the response
      if (messageType == ovrMessage_User_Get) {
        ovrUserHandle user = ovr_Message_GetUser(message);
        puts("Got a user");
        printf("Username: %s", ovr_User_GetOculusID(user));
      } else {
        // Normally, you would handle other message types, but we'll just ignore them
        // for this example
      }

      ovr_FreeMessage(message);
    }
  }
}
