HPL3/SOMA/Scripting/cVector2f

A two dimensional vector unit.

Fields

Field Name	Type	Description
x	float	The x value of the vector.
y	float	The y value of the vector.

Functions

Return Type	Function Name	Parameters	Description
float	GetElement	uint64 alIdx,	Gets the value at the given index. (Indices 0 and 1 are equal to x and y, respectively.)
float	Length		Returns the length of this vector.
float	Normalize		Returns the normalization factor for this vector. (See Remarks.)
void	SetElement	uint64 alIdx, float,	Sets the value at the given index to the given value. (Indices 0 and 1 are equal to x and y, respectively.)
float	SqrLength		Returns the length-squared of this vector.

Remarks

A normalized vector is a vector whose length is equal to one, otherwise known as a unit vector. To convert a vector into a unit vector, get the normalization factor by calling the Normalize function, then divide each of the vector's x and y coordinates by that factor.

cVector2f vBaseVector(2.0, 5.0);
float fNormFactor = vBaseVector.Normalize();
cVector2f vNormalizedVector(vBaseVector.x / fNormFactor, 
                            vBaseVector.y / fNormFactor);
