Method Detail

getDistanceTo

public float getDistanceTo(Point point)

getDistanceTo

public float getDistanceTo(float x,
                           float y)

rotateAround

public void rotateAround(Point center,
                         float degrees)

Rotates this Point around another Point

Parameters:

center - The Point to rotate around

degrees - The angle to rotate by in degrees

rotateAround

public void rotateAround(float centerX,
                         float centerY,
                         float degrees)

Rotates this Point around a coordinate

Parameters:

centerX - The x coordinate to rotate around

centerY - The y coordinate to rotate around

degrees - The angle to rotate by in degrees

isOnLineBetween

public boolean isOnLineBetween(Point a,
                               Point b)

Returns if this Point is between a and b on a line

Parameters:

a - Point a on a line

b - Point b on a line

Returns:

False if this Point is not on the same line as a and b OR is not between a and b on the same line

equals

public boolean equals(com.badlogic.gdx.math.Vector2 v)

Determines if another Vector2 is exactly equal to this one

Parameters:

v - The Vector2 to compare to

Returns:

True if both Vector2s x and y are exactly equal

equals

public boolean equals(com.badlogic.gdx.math.Vector2 v,
                      float delta)

Determines if this and a Vector2 are nearly equal. A delta of 0.1 means 0.0 and 0.1 would be considered equal but 0.0 and 0.11 would not.

Parameters:

v - The Vector2 to compare to

delta - The amount of error to allow for.

Returns:

True if the two points are equal allowing for a certain margin of error

equals

public boolean equals(float x,
                      float y,
                      float delta)

Determines if a coordinate is nearly equal to this one. A delta of 0.1 means 0.0 and 0.1 would be considered equal but 0.0 and 0.11 would not.

Parameters:

x - The x coordinate

y - The y coordinate

delta - The amount of error to allow for.

Returns:

True if the two points are equal allowing for a certain margin of error
