Description
This class represent a 4D vector (x, y, z, w). This class provides access to RLPy's internal 4D vector math library allowing 4D vectors to be handled easily, and in a manner compatible with internal RLPy data structures. It also supports operators and provides some convenient constants:
| Constant | Description |
|---|---|
| RVector4.ZERO | 4D zero vector: (0, 0, 0, 0) |
| RVector4.UNIT_X | 4D x unit vector: (1, 0, 0, 0) |
| RVector4.UNIT_Y | 4D y unit vector: (0, 1, 0, 0) |
| RVector4.UNIT_Z | 4D z unit vector: (0, 0, 1, 0) |
| RVector4.UNIT_W | 4D w unit vector: (0, 0, 0, 1) |
| RVector4.UNIT_XYZW | 4D vector: (1, 1, 1, 1) |
Constructor & Destructor

1 a = RLPy.RVector4()
__init__ ( a, b, c, d )
Initialize a new 4D vector object as a 4D vector: (x, y, z, w).
Parameters
- a [IN] A numerical value for x coordinate - float or int
- b [IN] A numerical value for y coordinate - float or int
- c [IN] A numerical value for z coordinate - float or int
- d [IN] A numerical value for w coordinate - float or int
1 a = RLPy.RVector4(1, 2, 3, 4)
__init__ ( *args )
Initialize a new 4D vector object with another 4D vector object: args. This new 4D vector object has the same value as *args.
