A two dimensional vector unit whose elements are stored as floats.
Contents
Constructors
Constructor | Description |
---|---|
cVector2f(float, float) |
Creates a cVector2f with the given element data.
|
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);
