How to prevent a physic body from rotating?

Greeting all gurus,

i wanna create a free fall character, which mean the character will stop falling while step on a platform.

But when my character hit other platform while falling, it seems weird to rotate my character.

How can i prevent the character from rotating while using it as physic body?

Use this code

object.isFixedRotation = true [import]uid: 14018 topic_id: 7506 reply_id: 26588[/import]
