Detailed Description

Vector2d class.

This class creates a list like object, which can be modified using the list protocol method. But unlike lists, its length is fixed: it always contain 2 floating point values. Thus it does not support the any list methods that would affect its length. The values within can be changed, usually via the bracket operator.

    # Supported list protocol methods:
    color = FBColor()
    len(color)
    print color[0]
        color[0] = 1.0

Warning:

Slicing is not supported by this object.

Member Function Documentation

int __len__

(

)

Returns the number of elements.

Corresponds to python: len(object)

float __getitem__

(

int

pIndex

)

Returns the ith component Corresponds to python: print v[1].

Parameters:

pIndex

Index of the components to get (0 to 1)

Returns:

Color component value.

__setitem__	(	int	pIndex,
		float	pComponentValue
	)

Sets the ith components Corresponds to python: v[1] = 0.5.

Parameters:

	pIndex	Index of the components to set (0 to 1)
	pComponentValue	Value of component to set

FBVector2d operator+

(
