RE: [Flashcoders] Vector.map()
You're right Kenneth.
var g:Vector.uint = Vector.uint([1,2,3,4,5]);
var hh:Vector.uint = g.slice();
var h:Vector.uint = g.map(mapper);
var a = 5;
function mapper(item:uint,ind:uint,g:Vector.uint):Vector.uint{
trace(g[ind]+30);
return g;
}
In this case, hh returns the vector, and h still returns null.

Dear coders,
Vector.map() is supposed to return a new Vector but it appears to return
nothing (undefined). Is this working for you?

Re: [Flashcoders] rotation cw ccw
You can't unless you assume that the maximum rotation speed is less than 180 degrees per update. This is due to the aliasing problem. This is, assuming that you don't actually know the rotation speed and are calculating the angular difference between two positions. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
RE: [Flashcoders] Vector.map()
function mapper needs to return an element of the new vector. In this
case, the vector is a vector of uint, so the mapper function needs to
return a uint, not a Vector. This makes sense because mapper is called
for every item in g. Say you wanted to populate h with the squares of
each element in g, you would return item * item.

RE: [Flashcoders] Vector.map()
It sure seems like the documentation is off from what it actually does. Maybe
in the mapper function, you can push each iteration out to a new array instead.
:-/\
Good luck!
