## Vector

A vector is a data type that contains a set of three float values.

### Components

Each element can be accessed individually by appending .x, .y, or .z to the variable name.

vector vec; float x = vec.x; float y = vec.y; float z = vec.z;

### Uses

Vectors can be used to hold the following:

- Position: x, y and z are in metres.
- Velocity: x, y and z represent speeds.
- Colour: Red is x, Green is y and Blue is z.

### Operators

Vectors support the following operations:

- Addition, Operator "+"
- Subtraction, Operator "-"
- Multiplication (Dot Product), Operator "*"
- Cross Product, Operator "%"

A vector can be multiplied or divided by a Quaternion to rotate it.

A vector can be multiplied or divided by a Float or Integer to scale it.

### Example

vector test=<1.0, 2.0, 3.0>; llOwnerSay((string)test.z); // Outputs 3.0

### Useful Snippets

integer IsVector(string s) { list split = llParseString2List(s, [" "], ["<", ">", ","]); if(llGetListLength(split) != 7)//we must check the list length, or the next test won't work properly. return FALSE; return !((string)((vector)s) == (string)((vector)((string)llListInsertList(split, ["-"], 5)))); //it works by trying to flip the sign on the Z element of the vector, //if it works or breaks the vector then the values won't match. //if the vector was already broken then the sign flip will have no affect and the values will match //we cast back to string so we can catch negative zero which allows for support of ZERO_VECTOR }//Strife Onizuka
