Unigine::Config Class
Header: | #include <UnigineConfig.h> |
The Config class is used to read values (settings) from the application configuration file (configs/default.config by default) and write them back to it.
Use the appropriate methods depending on the type of the target item. For example, to get the values of the following items, you should use the getInt() and getString() methods respectively:
...
<item name="show_fps" type="int">1</item>
<item name="system_script" type="string">unigine_project/unigine.usc</item>
...
Usage Example#
By using the Config class, you can save custom settings to the configuration file and then restore it when required. For example:
AppSystemLogic.h:
#include <UnigineLogic.h>
#include <UnigineConfig.h>
#include <UnigineConsole.h>
using namespace Unigine;
class AppSystemLogic : public Unigine::SystemLogic {
public:
AppSystemLogic();
virtual ~AppSystemLogic();
virtual int init();
virtual int update();
virtual int render();
virtual int shutdown();
virtual int destroy();
private:
Unigine::String player_avatar;
int skip_cutscenes;
int blood_enabled;
int bulletshell_lifetime;
};
AppSystemLogic.cpp:
#include "AppSystemLogic.h"
int AppSystemLogic::init() {
// read custom user-defined settings from the configuration file
player_avatar = Config::getString("player_avatar", "usa_soldier1");
skip_cutscenes = Config::getBool("skip_cutscenes", false);
blood_enabled = Config::getBool("blood_enabled", false);
bulletshell_lifetime = Config::getInt("bulletshell_lifetime", 100);
return 1;
}
int AppSystemLogic::shutdown() {
// automatically save the configuration file at shutdown
Config::setAutosave(true);
// write the custom settings to the configuration file
Config::setString("player_avatar", player_avatar.get());
Config::setBool("skip_cutscenes", skip_cutscenes);
Config::setBool("blood_enabled", blood_enabled);
Config::setInt("bulletshell_lifetime", bulletshell_lifetime);
// save data to the custom configuration file, which is different from the default one
Config::setPath("unigine_project/data/configs/my.config");
Config::save();
return 1;
}
