cVector2f
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, const | Gets the value at the given index. (Indices 0 and 1 are equal to x and y, respectively.) |
| void | SetElement | uint64 alIdx, float afVal, const | Sets the value at the given index to the given value. (Indices 0 and 1 are equal to x and y, respectively.) |
| float | SqrLength | const | Returns the length-squared of this vector. |
| float | Length | const | Returns the length of this vector. |
| float | Normalize | Returns the normalization factor for this vector. (See Remarks.) |
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);
