NWN2 has a special way of handling global variables. These are global variables in standard C++, however their use is somewhat different from how they are used in NWN2.
NWN2 Global Variables
NWN2 Global Variables are variables that can be accessed any where in a module.
NWN2 Global Variables come in three types: integer, float, and string.
NWN2 Global Variables can be used to store information from anywhere in a module.
NWN2 Global Variables can be used to get information from anywhere in a module.
NWN2 Global Variables should be used sparingly, especailly in large moduls with more than one developer since a developer may set its value in one part of the module and unknowingly corrupt other sections of the module.
NWN2 Global Variables add a powerful programming feature to the NWN2 scripting environement.
NWN2 Global Variables General Form
To declare and assign a value to a NWN2 Global Variable:
SetGlobalType("Identifier", Value);
Where:
Type is one of three allowed data types of: Int, Float, or String.
Identifier is the token used to identify the variable, this may be any string.
Value is the actual value assigned to the NWN2 Global Variable consistent with the data type.
NWN2 Global Variable Examples:
The following program illustrates examples of declaring and assigning values to the three allowed data types for a NWN2 Global Variable.
void main()
{
SetGlobalInt("Value1, 1);
SetGlobalFloat("Value2", 12.075);
SetGlobalString("Value2", "Welcome to NWN2!");
}
Explanation:
For the SetGlobalInt()
Term
Meaning
SetGlobalInt
Keyword for setting a NWN2 Global Variable of data type Integer (int).
"Value1"
The variable identifier. Note that it is of data type string and must be enclosed in quotes.
1
The value assigned to hte variable identifier. Note that since this sets a global int, this must be an integer.
For the SetGlobalFLoat()
Term
Meaning
SetGlobalFloat
Keyword for setting a NWN2 Global Variable of data type Float (float).
"Value2"
The variable identifier. Note that it is of data type string and must be enclosed in quotes.
12.076
The value assigned to the variable identifier. Note that since this sets a global float, this must be a floating point number.
For the SetGlobalString()
Term
Meaning
SetGlobalString
Keyword for setting a NWN2 Global Variable of data type String (string.)
"Value3"
The variable identiifer. Note that it is of data type string and must be enclosed in quotes.
"Welcome to NWN2!"
The value assigned to the variable identiifer. Note that since this sets a global string, this must be enclosed in quotes.
