Concatenation

Concatenation means add to the end or append. You will find that there are times when the ability to connect one string to another is very helpful. This section gives a brief but important example of how this is done.

Connecting Two Strings

The following program is an example of concatenating (connecting together) two strings:

void main( )
{
object oPC = GetEnteringObject();
string txtStringl = "This string has ";
string txtString2 = "another string connected to it.";
string txtBigString;
txtBigString = txtStringl + txtString2 + "Thanks!";
FloafngTextStringOnCreature(txtBigString, oPC);
}

An analysis of the above program yields:
•   Two string variables where declared each with a different string assinged to them
(txtStringI and txtString2).
•   A third string variable (txtBigString) was declared without an assignment.
•   Three strings were concatenated together and assigned to the variable txtBigString.
•   The + symbol is used to concatenate two or more strings.
•   You can concatenate assigned string variables or a string (as with the last string: "Thanks!").

When you try the above program in the NWN2 game using the previously completed Program I module, you will see the string:

This string has another string connected to it. Thanks!

...Over the top of your PC for every move over the triggered area.

An Application

An interesting application of concatenation is shown in the program below:

void main( )
{
object oPC = GetEnteringObject(); Jut Number;
string txtNumber; string Message;
Number = d6(2);
txtNumber = IntToString(Number);
Message = "The number I got is " + txtNumber; FloatingTextStringOnCreature(Message, oPC);
}

If the above program is compiled in the NWN2 editor with the previously created Program I module, the NWN2 game using that same module will dispay:

The number I got is XX

Where XX is the value of the random number the program received from the simulated six-sided dice.
