Hey. I am working on a 2D Terraria-Like game, and I needed some help with the movement. To handle both collisions and physics, I am using the Farseer Physics Engine. I have two questions, which are probably quite simple.

1. How can I make my character stop moving once the movement keys are released. With the code below, the character still continues to roll:

[source lang="java"]if(k.IsKeyDown(Keys.Left)) { circleBody.ApplyTorque(-1000); } else if (k.IsKeyDown(Keys.Right)) { circleBody.ApplyTorque(1000); }[/source]
2. Can I make the character not bounce at all after colliding with a platform? I have set the RestitutionCoefficient to 0, but it still bounces a very small amount.

3. Is there a way to prevent the character from rotating its texture?

Thanks for the help

As can see in the source code of the Body class there is a method called ResetDynamics(). I believe that this method is the one you are looking for.

2. Can I make the character not bounce at all after colliding with a platform? I have set the RestitutionCoefficient to 0, but it still bounces a very small amount.

There is a propriety in the class Body name FixedRotation. Set it to true to have the character keep its rotation to 0.
