RE: vectors

It would be nice to have such direct functionality in breve.

 

However, I found a way of extracting the coordinate in case somebody
needs it:

 

To get x coord:

 

myVec = (self get-location).

myAngle = angle(myVec, (1.0, 0, 0)).

x-val = (|myVec| * cos(myAngle)).

 

For y, use (0,1.0,0), for z use (0,0,1.0).

 

The result is the same up to 3-4 decimal places (because of the cosine).

How can I extract 1 coordinate of a vector?  I can't find such
functionality in the documentation.  I want to find out the x-coordinate
of a Mobile object but there is only a get-location function which
returns a vector.

 

Thanks,

 

Marcin
