# BIS_fnc_randomPosIntersection

*Function · Positions, Geometry · Arma 3 v1.82*

## Description

Returns random 2D position inside the intersection of two circles. [-1,-1] is returned if the circles do not intersect.

## Syntax

```sqf
[firstCircle, secondCircle, positioning1, positioning2] call BIS_fnc_randomPosIntersection
```

**Parameters:**

- `firstCircle`: [Object](../topics/Object.md), [String](../topics/String.md) or [Array](../topics/Array.md) - first circle. Can be a trigger, a marker or an array in form
  - 0: [Array](../topics/Array.md) - circleCenter
    - 0: [Number](../topics/Number.md) - coordinate X
    - 1: [Number](../topics/Number.md) - coordinate Y
  - 1: [Number](../topics/Number.md) - radius
- `secondCircle`: [Object](../topics/Object.md), [String](../topics/String.md) or [Array](../topics/Array.md) - second circle. Same as above.
- `positioning1`: [Number](../topics/Number.md) - (Optional, default -1) if a value between 0 and 1 is passed (0 and 1 included), then a gaussian distribution is used. This will influence the random position along the axis which connects the two circles' centers. A lower value means the position will be close to the first circle
- `positioning2`: [Number](../topics/Number.md) - (Optional, default -1) if a value between 0 and 1 is passed (0 and 1 included), then a gaussian distribution is used. This will influence the random position along the axis perpendicular to the axis which connects the two circles' centers

**Returns:** [Array](../topics/Array.md) - 2D Position

## Examples

### Example 1

```sqf
[trigger1, trigger2, 0.75, 0.75] call BIS_fnc_randomPosIntersection;
```
