Constants are pre-defined values that do not change–they’re constant: TRUE will always equal 1. However, this does not mean that values should be used instead; while there’s no technical reason not to, constants exist to simplify your code and make it easier to understand. It’s good coding practice to use them. This page is for general constants; function-specific ones should be documented on the functions page. You can find an almost complete list of constants & values on LexFile.
float
| PI | 3.1415926535897932384626433832795 (pi) |
| TWO_PI | 6.283185307179586476925286766559 (pi * 2) |
| PI_BY_TWO | 1.5707963267948966192313216916398 (pi / 2) |
| DEG_TO_RAD | To convert from degrees to radians (multiply, example: radian = 90 * DEG_TO_RAD;) |
| RAD_TO_DEG | To convert to radians from degrees (multiply, example: degree = PI_BY_TWO * RAD_TO_DEG;) |
| SQRT2 | 1.4142135623730950488016887242097 (square root of 2) |
integer
| TRUE | 1, an integer constant for boolean operations. |
| FALSE | 0, an integer constant for boolean operations. |
| DEBUG_CHANNEL | 2147483647, a special chat channel used to print to the Script Error Window. |
| PUBLIC_CHANNEL | 0, chat channel that broadcasts to all nearby users. |
| OBJECT_UNKNOWN_DETAIL | -1, an integer returned when an invalid object parameter type is passed to llGetObjectDetails. |
| INVENTORY_NONE | -1, an integer returned by llGetInventoryType when no item is found. |
string
NULL_KEY Indicates an empty key: “00000000-0000-0000-0000-000000000000”. This constant is typed as a string not as a key. EOF, “\n\n\n”, Indicates the last line (or a line past this) of a notecard was read (returned in the dataserver event), or that the notecard contained embedded objects.
| Substring | Replaced With |
| \t | four spaces |
| \n | new line |
| \” | double quote |
| \\ | backslash |
rotation
ZERO_ROTATION <0.0, 0.0, 0.0, 1.0> (Note that ZERO_ROTATION is not <0.0, 0.0, 0.0, 0.0>! This is important.)
vector
ZERO_VECTOR <0.0, 0.0, 0.0>
