comments, arrays and tokenize

I forgot to mention comments. You can easily provide feedback and notes to the users of your scripts (including yourself) by adding comments. Like this...

//this is a comment
int $firstNum = 1;
int $secondNum = 2;
//lets add the two variables
print ($firstNum + $secondNum + "\n");

OK thats pretty easy, sorry I didn't mention it earilier.

A quick note on arrays. An array is a varible that contains more than one peice of information. Like this...

int $myNumbers[] = {5, 7, 9};

Of course you can affect all or just parts of the array. You'll need to specify which part...

{
int $myNumbers[] = {5, 7, 9};
print ("The first number in the array is " + $myNumbers[0] + "\n");
print ("The second number in the array is " + $myNumbers[1] + "\n");
print ("The third number in the array is " + $myNumbers[2] + "\n");
}

Keep in mind the first item is labeled 0, not 1. I hope that makes sense for you. Now on to "tokenize".

Tokenize is a function that takes a string and breaks it into an array via a character you specify. Lets say you have this...

string $myString = "lf_Arm_JNT";

As in "Left arm joint". You simply want to rename it to rt_Arm_JNT. Here is how tokenize can help.

{
string $myString = "lf_Arm_JNT";
string $right = "rt";
string $newString;

//we'll need another string to store the parts of the first, hang in there I'll show ya
string $myToks[];

tokenize($myString, "_", $myToks);
string $newString = ($right + "_" + $myToks[1] + "_" + $myToks[2] + "\n");
print ($newString + "\n");
}

So tokenize reads like this in english...

tokenize(this string, by this character, and store all the parts in this other string)

pretty cool beavis.
