FlxTilemap.ray() Result value always null

[cr0ybot]

Supposedly AS3 passes all objects as reference, but this does not appear to be the case with the "Result" FlxPoint in FlxTilemap.ray(). Checking the Result value always results in null.

See this stackoverflow question for a very similar situation:
http://stackoverflow.com/questions/3708371/actionscript-pass-by-reference

Why is it necessary to do the raycast in this manner? Why return a boolean at all if you can just return the FlxPoint (if the ray hits anything) and check for null?

I don't think the error is with flixel here. This code:

var result:FlxPoint = new FlxPoint();
tile.ray(startPoint, endPoint, result);
trace(result.x + " " + result.y);

works fine for me. I think you were probably doing this:

var result:FlxPoint;
tilemap.ray(startPoint, endPoint, result);

which is essentially just passing null as the third parameter and will always give you null back.
