# SDK Integration

1.1 Build libthinkingdata.a file

TE SDK relies on rapidjson (opens new window)parsing library, you need to download rapidjson library.
Download the SDK source code, modify the CMakeLists.txt file in the SDK, and select the data consumers you need for packaging (details can refer to the CMakeLists.txt file in the SDK source code). Here is an example of the most common logconsumer:

cmake_minimum_required(VERSION 3.12)
project(ThinkingData)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_STANDARD 11)

message(STATUS "[${PROJECT_NAME}] current cmake version: ${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION}.${CMAKE_PATCH_VERSION}")
message(STATUS "[${PROJECT_NAME}] CMAKE_HOST_SYSTEM: ${CMAKE_HOST_SYSTEM} ")

if(NOT CMAKE_BUILD_TYPE)
    set(CMAKE_BUILD_TYPE release CACHE STRING "Build Type" FORCE)
endif()

message(STATUS "[${PROJECT_NAME}] Build type:${CMAKE_BUILD_TYPE}")

message(STATUS "[${PROJECT_NAME}] Debug configuration:${CMAKE_CXX_FLAGS_DEBUG}")

message(STATUS "[${PROJECT_NAME}] release configuration:${CMAKE_CXX_FLAGS_RELEASE}")

message(STATUS "[${PROJECT_NAME}] release configuration with debug info:${CMAKE_CXX_FLAGS_RELWITHDEBINFO}")

message(STATUS "[${PROJECT_NAME}] minimal release configuration:${CMAKE_CXX_FLAGS_MINSIZEREL}")

include_directories(include)

 #
 # log consumer. Recommended for production environments
 #
 set(TE_LIB_NAME thinkingdata)
 add_library(${TE_LIB_NAME} src/TDAnalytics.cpp src/TDUtils.cpp src/TDLoggerConsumer.cpp src/TDConsumer.cpp)
 if(UNIX)
   find_package(Threads REQUIRED)
   target_link_libraries(${TE_LIB_NAME} Threads::Threads)
 endif()

The rapidjson library contains only header files.
1. Put the rapidjson in the following path if your project has not included the rapidjson library before:
The contents of the TDJsonParse.h file need to be modified if your project has previously included the rapidjson library. You don't need to import rapidjson again:

1.2 Logbus Integration

We recommend using SDK+LogBus to track and report data on server. You can refer to the following documents to complete the installation of Logbus: LogBus User Guide

# Initialization

The following is the sample code for SDK initialization:

#include "../include/TDAnalytics.h"
#include "../include/TDLoggerConsumer.h"
#include "../include/TDDebugConsumer.h"
#include "../include/TDBatchConsumer.h"

using namespace thinkingDataAnalytics;

int main(int argc, char *argv[]) {
    TDLoggerConsumer::Config config = TDLoggerConsumer::Config("LOG_DIRECTORY", 20, 500, TDLoggerConsumer::HOURLY);
    config.fileNamePrefix = "te";
    config.rotateMode = TDLoggerConsumer::HOURLY;

    TDConsumer *consumer = new TDLoggerConsumer(config);
    TDAnalytics te(*consumer, false);
}

LOG_DIRECTORY is the local folder path.

# Common Features

In order to ensure that the distinct ID and account ID can be bound smoothly, if your game uses the distinct ID and account ID, we strongly recommend that you upload these two IDs at the same time, otherwise the account will not match, causing users to double count. For specific ID binding rules, please refer to the chapter on User Identification Rules.

# 3.1 Sending Events

You can call track to upload events. It is suggested that you set event properties based on the data tracking plan drafted previously. Here is an example of a user buying an item:

TDPropertiesNode event_properties;
event_properties.SetString("name1", "XZ_debug");
event_properties.SetString("name2", "logbugs");
event_properties.SetString("name3", "name3");
event_properties.SetString("#uuid", "1234567890");
event_properties.SetNumber("test_number_int", 3);
event_properties.SetNumber("test_number_double", 3.14);
event_properties.SetBool("test_bool", true);
std::string test_string = "test_string";
event_properties.SetString("test_stl_string1", test_string);
event_properties.SetDateTime("test_time1", time(nullptr), 0);
timeb t = {};
ftime(&t);
event_properties.SetDateTime("#time", t.time, t.millitm);
std::vector<std::string> test_list;
test_list.emplace_back("item11");
test_list.emplace_back("item21");
event_properties.SetList("test_list1", test_list);

// track event
te.track("accountId", "distinctId", "eventName", event_properties);

Key is the name of the property and refers to the string type. It must start with a character, and contain numbers, characters (insensitive to case, and upper cases would be transformed into lower cases by TE) and underscores "_", with a maximum length of 50 characters.
Value, the value of the property, supports string, numbers, Boolean, time, object, array object, and array

The requirements for event properties and user properties are the same as that for super properties

# 3.2 User Properties

You can set general user properties by calling user_set API. The original properties would be replaced by the properties uploaded via this API. If no user properties are set before, user properties will be newly created. The type of newly-created user properties must conform to that of the uploaded properties. User name setting is taken as the example here:

// user_set
TDPropertiesNode userSet_properties;
userSet_properties.SetString("userName", "test");
te.user_set("accountId", "distinctId", userSet_properties);

# Best Practice

The following sample code covers all the above-mentioned operations. It is recommended that the codes be used in the following steps:

// Import header file (adjust the path yourself)
#include "../include/TDAnalytics.h"
#include "../include/TDLoggerConsumer.h"

using namespace thinkingDataAnalytics;

TDLoggerConsumer::Config config = TDLoggerConsumer::Config("LOG_DIRECTORY", 20, 500, TDLoggerConsumer::HOURLY);
config.fileNamePrefix = "te";
config.rotateMode = TDLoggerConsumer::HOURLY;

TDConsumer *consumer = new TDLoggerConsumer(config);
TDAnalytics te(*consumer, false);

TDPropertiesNode event_properties;
event_properties.SetString("name1", "XZ_debug");;
event_properties.SetNumber("test_number_int", 3);
event_properties.SetBool("test_bool", true);
te.track("accountId", "distinctId", "eventName", event_properties);

TDPropertiesNode userSet_properties;
userSet_properties.SetString("userName", "test");
te.user_set("accountId", "distinctId", userSet_properties);

te.flush();
