Variables
Global vs Local
global int $varname = 3; – This is a global variable and can be seen by other scripts
Defining a Variable
int $varname; – Integer value. Example int $varname = 10;
float $varname; – Float value. Example float $varname = 1.2345;
string $varname; – Creating a string. Example string $varname = “Hello World”;
vector $varname; – Creates a 3 digit vector. Example vector $varname = <<1,0,0>> or = <<255,128,0>>;
$varname[]; – This is for arrays
matrix $varname[3][4]; – Creates a Matrix
Int and Floats math
int $varA = 5;
float $varB = 5.123;
$varA + $varB = 10; < – You can get a float out of a int
$varB + $varA = 10.123;
Strings
string $varname; – Creating a string. Example string $varname = “Hello World”;
Line Options
"\n" = New line
"\t" = Tab
"\\" = Backslash
Examples:
string $varname = "Hello World";
// Result: “Hello world” //
print ($varname + ", Hello computer" ;
// Result: “Hello world, Hello computer” //
Vectors
Vectors are always three floats values
Examples:
vector $varname = <<255,128,0>>;
// Result: <<255, 128, 0>> //
print ($varname.x)
// Result: 255 //
Set a value
$varname = <<123,$varname.y,$varname.z>>;
// Result: <<123, 128, 0>> //
Arrays
int $varname[] = {1,2,3};
float $varname[] = {1.25,2.8,3.0};
string $varname[] = {"one","two","three"};
clear($varname); – Will clear an array out
Examples:
int $varname[] = {1,2,3};
$varname[0] = 9
// Result: 9 //
int $varname[] = {1,2,3};
$varname[0] = 9;
print ($varname);
// Result: 9 //
// Result: 2 //
// Result: 3 //
Looking for a value in a array. This returns a True (1) or False (0).
string $Lists[] = {"one","two","three"};
string $UserInput = "three";
print (stringArrayContains($UserInput, $Lists));// Result: 1 //
Matrix
matrix $matrixname[Row#][Column#] = << 1, 2, 3, 4 ; 5, 6, 7, 8 ; 9, 10, 11, 12>>;// Result: << 1 2 3 4; 5 6 7 8; 9 10 11 12 >> //
| 1 | 2 | 3 | 4 |
| 5 | 6 | 7 | 8 |
| 9 | 10 | 11 | 12 |

Finding Version name
import os
print "PATH : " + cmds.file(q=True, sn=True)
print "BASENAME : " + os.path.basename(cmds.file(q=True, sn=True).split('.')[0])
print "VERSION : _v"+ os.path.basename(cmds.file(q=True, sn=True)).split('.')[1].split('mb')[0]
Random Rotate:
vector $rndRot = << 0,0,90 >>;
for ($object in `ls -sl -tr`)
rotate `rand ($rndRot.x)` `rand ($rndRot.y)` `rand ($rndRot.z)` $object;
