I need to do some vector operations on a 2d Asteroids type game.

I found this page here.....

http://geom-java.sourceforge.net/api/math/geom2d/Vector2D.html

Unfortunately, I have no idea what to 'import' to get this to work.

I saw in an online example someone used the following....

import math.geom2d.Vector2D;

when I tried this, I only got....

error: package math.geom2d does not exist
import math.geom2d.Vector2D;

I am totally new to Java, and im not sure what I am doing wrong, other than there might be something I need to download extra?

And if so... how will others run my java app or applet if they too dont have the 'something' i might be missing?

Thanks for any help

Yes, you need to download and install the geom-java package, as it is not part of the standard Java library. You should then be able to either state it as a requirement for future users, or perhaps even bundle it along with your java program (subject to conditions).

“If I understand the standard right it is legal and safe to do this but the resulting value could be anything.”
