engine.config Functions
Warning
UnigineScript is deprecated and will be removed in future releases. Please consider using C#/C++ instead, as these APIs are the preferred ones. Availability of new Engine features in UnigineScipt is not guaranteed, as the current level of support assumes only fixing critical issues.
The Config class is used to read values (settings) from the engine configuration file (unigine.cfg by default) and write back into it.
Notice
By using the Config class functionality, it is possible to read from and write to the engine configuration file only (the file specified by using the -engine_config command-line option). To write application-specific settings to a different file, use the File, Xml or Json classes.
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 corespondingly:
Source code (XML)
...
<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:
Source code (UnigineScript)
#include <core/unigine.h>
string player_avatar;
int skip_cutscenes;
int blood_enabled;
int bulletshell_lifetime;
int init() {
// read custom user-defined settings from the configuration file
player_avatar = engine.config.getString("player_avatar", "usa_soldier1");
skip_cutscenes = engine.config.getBool("skip_cutscenes", 0);
blood_enabled = engine.config.getBool("blood_enabled", 0);
bulletshell_lifetime = engine.config.getInt("bulletshell_lifetime", 100);
return 1;
}
int shutdown() {
// check whether data can be written to the configuration file
if (engine.console.getInt("config_readonly") == 1) engine.console.setInt("config_readonly",0);
// write the custom settings to the configuration file
engine.config.setString("player_avatar", player_avatar);
engine.config.setBool("skip_cutscenes", skip_cutscenes);
engine.config.setBool("blood_enabled", blood_enabled);
engine.config.setInt("bulletshell_lifetime", bulletshell_lifetime);
return 1;
}In UnigineScript, changes made for the configuration file are saved automatically on the application shutdown.
