string GetPropertyText (string PropName)
 Returns the value of the specified property typecasted to string. It is not possible to access default properties in this manner.
bool SetPropertyText (string PropName, string PropValue)
 Assigns a value to the specified public nonconstant property of an object. Only use this for properties that can be typecasted from string. Properties declared as private, protected or const cannot be altered this way, and will return false just as if the named property did not exist at all.
ClearConfig (optional string PropName)
 Remove this object's section from the appropriate .ini file, and reload the script defaults for this object. If PropertyName is specified, only remove and reload that property, if found.
ResetConfig (optional string PropName)
 If object's class does not have a section in the default.ini or defuser.ini, ResetConfig() now performs ClearConfig(). Otherwise, functionality is same as before. If PropertyName is specified, only reset and reload that property, if found.
SaveConfig ()
 Saves the current values of config and globalconfig variables of this object to the ini file and sets them as default values for the object's class.
StaticClearConfig (optional string PropName)
 Static version of ClearConfig().
StaticSaveConfig ()
 Saves the default values of config and globalconfig variables of this object's class to the ini file.
Logging
Log (coerce string S, optional name Tag)
 Writes a line to the log file. The line begins with the Tag (or "ScriptLog:" if Tag was not specified), followed by the log string.
Warn (coerce string S)
 Same like Log(), but the line starts with "ScriptWarning:" and contains information about the object, state and function that called Warn().
string Localize (string SectionName, string KeyName, string PackageName)
 Returns the string found in PackageName.int in the [SectionName] section. Logs an error if no localization for the specified string is found.
Iterator functions
AllObjects (class baseClass, out Object obj)
 Iterates through all objects with the same or derived class as baseClass'.
Other functions
String GetItemName (string FullName)
 Returns the class name without the package/group prefix.
StopWatch (optional bool bStop)
 Call with false to start the stopwatch. Every log created with log() will be prefixed with a millisecond offset from when the stopwatch was started. Call with true to stop the stopwatch and reset the timer. When stopped the engine will output a log entry containing the total time difference.
