Protecting Your Data with a Password

In order to protect your source code and content, you are recommended to use the Archiver tool to archive your resources into UNG archives. It implements data encrypting to avoid unauthorized access and provides a password protection.

To protect resources, you need to create an archive with the password specified and pass the same password on engine initialization. The workflow is as follows:

  • Create an UNG archive with the specified password. For example, to create an archive named files.ung with the 12345 password that contains the textures directory, pass the following CLI:
    Shell commands
    ung_x86 -o files.ung -d textures -p 12345
  • Specify the same password to be passed on engine initialization in the <your_project_name>.cpp file:
    Source code (C++)
    #include <UnigineEngine.h>
    #include "AppSystemLogic.h"
    #include "AppWorldLogic.h"
    #include "AppEditorLogic.h"
    #ifdef _WIN32
    	int wmain(int argc,wchar_t *argv[]) {
    	int main(int argc,char *argv[]) {
    	Unigine::EnginePtr engine(UNIGINE_VERSION,argc,argv, "<your_project_name>", "12345");
    	AppSystemLogic system_logic;
    	AppWorldLogic world_logic;
    	AppEditorLogic editor_logic;
    	return 0;
    If you pass a project name during engine initialization, this means the engine will store its rewritable data (such as logs, cache and configuration files) in user profile (in C:\Users\<username> on Windows or in /home/<username> on Linux and Mac OS X) rather than <UnigineSDK/bin/ or <UnigineSDK/data/ folders.
    On engine initialization, you can pass NULL as the 4th argument if you don't need that data is stored in user profile:
    Source code (UnigineScript)
    // engine initialization
    	Unigine::EnginePtr engine(UNIGINE_VERSION,argc,argv,NULL,"12345");
