Instance Method Summary

• #/(other : SF::Vector2)

  Memberwise division of two vectors

• #<=>(other : SF::Vector2f)

  Compares two Vectors based on length

• #<=>(length : Float32)

  Compares this vector's length to the given scalar

• #<=>(other : Float64)

  Compares this vector's length to the given scalar

• #<=>(other)

  Compares this vector's length to the given scalar

• #==(other : Number)

  Equality to a scalar: returns true if length is equal to other

• #abs

  Returns a vector with the same x and y but both positive

• #angle

  Returns the angle between the vector and the x-axis

• #angle_deg

  Returns the angle between the vector and the x-axis in degrees

• #angle_to(other : SF::Vector2f)

  Returns the angle between this Vector and another (the sign indicates which Vector is ahead)

• #angle_to_deg(other : SF::Vector2f)

  Returns the angle between this Vector and another in degrees (the sign indicates which Vector is ahead)

• #cross(other : SF::Vector2(T))

  Returns the z component of the cross product of two vectors

• #dist(other : SF::Vector2(T))

  Returns the euclidean distance to another point

• #dot(other : SF::Vector2(T))

  Returns the dot product between two vectors

• #length
• #length_squared
• #magnitude

  Same as length

• #magnitude_squared

  Same as length_squared

• #manhattan(other : SF::Vector2(T))

  Returns the manhattan distance to another point

• #manhattan

  Returns the manhattan distance of this vector's destination from the origin

• #new_x(nx)

  Returns a copy of self with a new x value

• #new_y(ny)

  Returns a copy of self with a new y value

• #normalized

  Returns a vector with the same direction of the original vector, but with a length of one unit

• #rotate(angle : Float32)

  Returns this vector rotated by the given angle around the origin

• #rotate(angle)

  Returns this vector rotated by the given angle around the origin

• #unit

  Returns a vector with the same direction of the original vector, but with a length of one unit
