Description

hrPrev

HRESULT

HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)

aPoint1

TcVnPoint2_DINT&

Point 1

aPoint2

TcVnPoint2_DINT&

Point 2

aDirection

TcVnVector2_LREAL&

Returns the direction vector from aPoint1 to aPoint2

bNormalize

bool

If true, aDirection length is normalized to 1, otherwise aDirection length is the distance between aPoint1 and aPoint2
