EnginePtr Class

Header: #include <UnigineEngine.h>

This class is an analogue of the C++ std::auto_ptr class template. It automatically destroys the engine instance when the function is destroyed.

Source code (C++)
Unigine::EnginePtr engine(...);
engine->main();

EnginePtr Class

Members


EnginePtr ( ) #

An EnginePtr constructor.

EnginePtr ( const EnginePtr & ptr ) #

An EnginePtr constructor.

Arguments

  • const EnginePtr & ptr - Pointer to the EnginePtr instance.

EnginePtr ( int argc, char ** argv, const char * project = 0, const char * password = 0 ) #

An EnginePtr constructor.

Arguments

  • int argc - Number of command line arguments.
  • char ** argv - Array of command line arguments values.
  • const char * project - Project name. If this parameter is set, it forces the engine to store rewritable data (such as log file, cache files, config files) in user profile rather than in a directory with binaries. Notice that only the project name is required to pass in for this parameter, not the full path to the project. If there is no need to change location of such files, pass the 0 value.
  • const char * password - Password for the filesystem archives. Notice that the specified password must be the same as for the project archive (if it exists). Pass the 0 value if you do not need to set a password.

EnginePtr ( int argc, wchar_t ** argv, const char * project = 0, const char * password = 0 ) #

An EnginePtr constructor.

Arguments

  • int argc - Number of command line arguments.
  • wchar_t ** argv - Array of command line arguments values.
  • const char * project - Project name. If this parameter is set, it forces the engine to store rewritable data (such as log file, cache files, config files) in user profile rather than in a directory with binaries. Notice that only the project name is required to pass in for this parameter, not the full path to the project. If there is no need to change location of such files, pass the 0 value.
  • const char * password - Password for the filesystem archives. Notice that the specified password must be the same as for the project archive (if it exists). Pass the 0 value if you do not need to set a password.

EnginePtr ( App * app, int argc, char ** argv, const char * project, const char * password ) #

Arguments

  • App * app - Pointer to the graphics App class. Pass the 0 value to ignore this parameter.
  • int argc - Number of command line arguments.
  • char ** argv - Array of command line arguments values.
  • const char * project - Project name. If this parameter is set, it forces the engine to store rewritable data (such as log file, cache files, config files) in user profile rather than in a directory with binaries. Notice that only the project name is required to pass in for this parameter, not the full path to the project. If there is no need to change location of such files, pass the 0 value.
  • const char * password - Password for the filesystem archives. Notice that the specified password must be the same as for the project archive (if it exists). Pass the 0 value if you do not need to set a password.
