`SwipeDirectionDetector.Direction`	`getDirection(float x1, float y1, float x2, float y2)`	Given two points in the plane p1=(x1, x2) and p2=(y1, y1), this methodreturns the direction that an arrow pointing from p1 to p2 would have.
`double`	`getAngle(float x1, float y1, float x2, float y2)`	Finds the angle between two points in the plane (x1,y1) and (x2, y2)The angle is measured with 0/360 being the X-axis to the right, anglesincrease counter clockwise.

    Parameters:
    
    x1 - the x position of the first point
    
    y1 - the y position of the first point
    
    x2 - the x position of the second point
    
    y2 - the y position of the second point
  - getAngle
```
 double getAngle(float x1, float y1, float x2, float y2)
```
    Finds the angle between two points in the plane (x1,y1) and (x2, y2)The angle is measured with 0/360 being the X-axis to the right, anglesincrease counter clockwise.
    
    Parameters:
    
    x1 - the x position of the first point
    
    y1 - the y position of the first point
    
    x2 - the x position of the second point
    
    y2 - the y position of the second point
