Member Function Documentation

◆ normalized()

LPoint2i LPoint2i::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 953 of file lpoint2.h.

◆ project()

LPoint2i LPoint2i::project ( const LVecBase2i 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 965 of file lpoint2.h.

◆ unit_x()

const LPoint2i & LPoint2i::unit_x ( )
inlinestatic

Returns a unit X point.

Definition at line 850 of file lpoint2.h.

◆ unit_y()

const LPoint2i & LPoint2i::unit_y ( )
inlinestatic

Returns a unit Y point.

Definition at line 860 of file lpoint2.h.

◆ zero()

const LPoint2i & LPoint2i::zero ( )
inlinestatic

Returns a zero-length point.

Definition at line 840 of file lpoint2.h.
