I think I'm missing some easy way to do this physics

I have question which may be easy to this.

I have a ball (it will talk later), after a few seconds, I'd like it to move right and knock some blocks, where the blocks fall using built in physics.

When I try to do just a ball, I can find a way for the ball to wait before moving. The physics dialog for the layer seems to want it to move at the start of the scene.

I tried to add a person to the physics layer who does a kick to kick the ball from off-screen, but I couldn't get that to work either.

What am I missing here? It must be something simple? I also did a test to see if I could create a layer at the chosen time with the ball and start movement at that frame, but somehow the ball, created in frame 48 still appears and moves in frame 1.

This is simple. In the layer properties for each layer, under the physics tab, select the start asleep option. Go to the frame you want the ball to start rolling, select the ball layer in the layer palette,and hit ctr+shift+n for nudge physics. Also you need a floor layer with the physics set to non-moving option or else your layers will fall off the screen.
here's a sample file ASP7

[solved] it works!

@jonbo - exactly what I was looking for, and double thanks for the example .anime file.

The manual (p498) says to use Shift-Cntl-N to nudge, but the dialog never popped up. After rereading the manuals animations section and seeing your file, it made more sense to me. I think the frequent discussion of "nudge" in the manual is centered around cntl-arrow and shift-cntl-arrow, so I was trying two different things that didn't work (in addition to all the work arounds I also tried).

This feature should really have a video tutorial.

Big thanks again!
