Member Function Documentation

◆ normalized()

LVector2f LVector2f::normalized ( ) const
inline

Normalizes the vector and returns the normalized vector as a copy.

If the vector was a zero-length vector, a zero length vector will be returned.

Definition at line 322 of file lvector2.h.

◆ project()

LVector2f LVector2f::project ( const LVecBase2f onto) const
inline

Returns a new vector representing the projection of this vector onto another one.

The resulting vector will be a scalar multiple of onto.

Definition at line 334 of file lvector2.h.

◆ signed_angle_deg()

float LVector2f::signed_angle_deg ( const LVector2f other) const
inline

returns the signed angled between two vectors.

normalization is NOT necessary

Definition at line 356 of file lvector2.h.

◆ signed_angle_rad()

float LVector2f::signed_angle_rad ( const LVector2f other) const
inline

returns the signed angled between two vectors.

normalization is NOT necessary

Definition at line 345 of file lvector2.h.

◆ unit_x()

const LVector2f & LVector2f::unit_x ( )
inlinestatic

Returns a unit X vector.

Definition at line 229 of file lvector2.h.

◆ unit_y()

const LVector2f & LVector2f::unit_y ( )
inlinestatic

Returns a unit Y vector.

Definition at line 239 of file lvector2.h.

◆ zero()

const LVector2f & LVector2f::zero ( )
inlinestatic

Returns a zero-length vector.

Definition at line 219 of file lvector2.h.
