Moving an Inifite mass object? [solved]

[lucas]

Hi,
I'm trying to create a game where objects fall onto a mouse controlled paddle, and the aim is to catch them all without dropping any. I gave the paddle (which I don't want to move) infinate mass and moment of inertia, and to move it I set the position to the mouse's x value every step. However, like the documentation says, it plays with the collisions a little bit. When I move the paddle to the side into an object, instead of pushing the object the object just goes inside the paddle and falls off the screen.
Is this because I'm setting the position every step, and if it is, how can if move the paddle?

Thanks!

If I where to do this, I'd not adjust the position directly, but adjust the velocity instead.
Then if I read right, you want the shapes that land on the pad to "stick", I'd remove the shapes cpbody and add it to the pad's cpbody instead.
I could be wrong, but thats how I would do it.

The problem is that you aren't giving the paddle any velocity. It's only moving around because you are setting it's position every frame. When the ball hits it, the paddle will always have a velocity of zero.

Keep in mind that mouse events are really coarse and you can't rely on them to produce smooth movements. You'll have to smooth them out if you want to get a good consistent reaction out of them.

Sorry, I thought I edited my post to say I figured out the problem. I made it change the velocity and it works fine.

Thanks!
