# vectorDotProduct

*Command · Math - Vectors · Arma 3 v1.22*

## Description

Dot product of two 3D vectors.

> [!NOTE]
> **Since Arma 3 v2.14:** Since Arma 3 v2.14 any count of numbers is valid, but both arrays must be same length.
>
> Before Arma 3 v2.14, the first argument had to be vector 3D, or Arma 3 v2.00 2D (With z coordinate defaulted to 0)

## Syntax

```sqf
vector1 vectorDotProduct vector2
```

**Parameters:**

- `vector1`: [Array](../topics/Array.md) of [Number](../topics/Number.md)s
- `vector2`: [Array](../topics/Array.md) of [Number](../topics/Number.md)s

**Returns:** [Number](../topics/Number.md)

## Examples

### Example 1

```sqf
_dot = [1,0,1] vectorDotProduct [0,0,2];
```
