Can you change an Objects Physics properties on the fly?

Just like the subject says, im wondering if there is any way to change the physics properties of an object during runtime. I Do NOT mean the shape. For example if i have a ball rolling, it starts having a friction of 10, after it hits a trigger, i would like to increase its friction to 50. Anyone know if this is possible? thank you [import]uid: 19620 topic_id: 7873 reply_id: 307873[/import]
