Am I doing something wrong here? (capx inside)

I got a few blocks with the Platform and Solid behaviors.

All I want them to do is to STOP when they fall on top of each other.

But what they do is this:

Some stop correctly while others blend.

I'm not sure I'm doing something wrong here; maybe the Platform behavior is not the way to go and I should create my own gravity event (which I'm not sure how to do).

I have made sure my sprites are all the same dimensions (100x100) and have centered hotspots.

Here is the capx:

The platform movement probably isn't ideal for this - it's designed for just the player in a jump and run game.

Still, it's a minor bug in the platform movement that sometimes the object "floats" a fraction of a pixel off the floor. I'll see if I can fix it for the next build.

Thanks Ashley
