)

const

Calculates the angle of this vector in grad in the trigonometric sense. This method has been suggested by Pr3t3nd3r.

Returns:

Returns a value between 0 and 360.

References core::atan(), core::RADTODEG, X, and Y.

f32 core::vector2d::getAngleWith

(

const vector2d &

b

)

const

Calculates the angle between this vector and another one in grad.

Returns:

Returns a value between 0 and 90.

f32 core::vector2d::getDistanceFrom

(

const vector2d &

other

)

const

Returns distance from an other point. Here, the vector is interpreted as point in 2 dimensional space.
