BetweenPoints
<static> BetweenPoints(point1, point2)
Description:
Find the angle of a segment from (point1.x, point1.y) -> (point2.x, point2.y).
Calculates the angle of the vector from the first point to the second point.
Parameters:
| name | type | optional | description |
|---|---|---|---|
| point1 | Phaser.Types.Math.Vector2Like | No | The first point. |

BetweenPointsY
<static> BetweenPointsY(point1, point2)
Description:
Find the angle of a segment from (point1.x, point1.y) -> (point2.x, point2.y).
The difference between this method and Phaser.Math.Angle.BetweenPoints is that this assumes the y coordinate travels down the screen.
Parameters:
| name | type | optional | description |
|---|---|---|---|
| point1 | Phaser.Types.Math.Vector2Like | No | The first point. |
| point2 | Phaser.Types.Math.Vector2Like | No | The second point. |
Returns: number - The angle in radians.

BetweenY
<static> BetweenY(x1, y1, x2, y2)
Description:
Find the angle of a segment from (x1, y1) -> (x2, y2).
The difference between this method and Phaser.Math.Angle.Between is that this assumes the y coordinate travels down the screen.
Parameters:
| name | type | optional | description |
|---|---|---|---|
| x1 | number | No | The x coordinate of the first point. |
| y1 | number | No | The y coordinate of the first point. |
| x2 | number | No | The x coordinate of the second point. |
| y2 | number | No | The y coordinate of the second point. |
Returns: number - The angle in radians.

CounterClockwise
<static> CounterClockwise(angle)
Description:
Takes an angle in Phasers default clockwise format and converts it so that 0 is North, 90 is West, 180 is South and 270 is East, therefore running counter-clockwise instead of clockwise.
You can pass in the angle from a Game Object using:
var converted = CounterClockwise(gameobject.rotation);
All values for this function are in radians.
Parameters:
| name | type | optional | description |
|---|---|---|---|
| angle | number | No | The angle to convert, in radians. |
Returns: number - The converted angle, in radians.

Normalize
<static> Normalize(angle)
Description:
Normalize an angle to the [0, 2pi] range.
Parameters:
| name | type | optional | description |
|---|---|---|---|
| angle | number | No | The angle to normalize, in radians. |
Returns: number - The normalized angle, in radians.

Random
<static> Random()
Description:
Returns a random angle in the range [-pi, pi].
Returns: number - The angle, in radians.
Source: src/math/angle/Random.js#L10
Since: 3.23.0
RandomDegrees
<static> RandomDegrees()
Description:
Returns a random angle in the range [-180, 180].
Returns: number - The angle, in degrees.
Source: src/math/angle/RandomDegrees.js#L10
Since: 3.23.0
Reverse
<static> Reverse(angle)
Description:
Reverse the given angle.
Parameters:
| name | type | optional | description |
|---|---|---|---|
| angle | number | No | The angle to reverse, in radians. |
Returns: number - The reversed angle, in radians.
Source: src/math/angle/Reverse.js#L9
Since: 3.0.0
RotateTo
<static> RotateTo(currentAngle, targetAngle, [lerp])
Description:
Rotates currentAngle towards targetAngle, taking the shortest rotation distance. The lerp argument is the amount to rotate by in this call.
Parameters:
| name | type | optional | default | description |
|---|---|---|---|---|
| currentAngle | number | No | The current angle, in radians. | |
| targetAngle | number | No | The target angle to rotate to, in radians. | |
| lerp | number | Yes | 0.05 | The lerp value to add to the current angle. |
Returns: number - The adjusted angle.

ShortestBetween
<static> ShortestBetween(angle1, angle2)
Description:
Gets the shortest angle between angle1 and angle2.
Both angles must be in the range -180 to 180, which is the same clamped
range that sprite.angle uses, so you can pass in two sprite angles to
this method and get the shortest angle back between the two of them.
The angle returned will be in the same range. If the returned angle is greater than 0 then it's a counter-clockwise rotation, if < 0 then it's a clockwise rotation.
Parameters:
| name | type | optional | description |
|---|---|---|---|
| angle1 | number | No | The first angle in the range -180 to 180. |
| angle2 | number | No | The second angle in the range -180 to 180. |
Returns: number - The shortest angle, in degrees. If greater than zero it's a counter-clockwise rotation.

Parameters:
| name | type | optional | description |
|---|---|---|---|
| angle | number | No | The angle to wrap, in radians. |
Returns: number - The wrapped angle, in radians.
