Newb question re: physics

Ok, I guess this is probably pretty easy, but here goes anyway.

I want an apple to fall from a tree and hit the ground. I put physics behaviour on the apple, checked box that says gravity. I put physics behaviour on the placeholder for the ground, and checked box for immovable. But the apple still falls through the ground. Sorry for the simple question, but I am not sure where I am going wrong...

Thanks in advance. M

The steps you described should work just fine.

Maybe the collision mask of your physics behavior is accidently set to NONE on the apple or the ground. That's my only guess for now.

sounds like it should work.

You could post a .cap file if you want someone to have a look at it.

Use either the uploads forum or put a link to a remote file in this thread.

False alarm, I was struck witht he answer in my sleep last night. I had, rather stupidly, had the ground as a tiled background, not a sprite... Thanks anyway, I will now slink away, somewhat embarrassed.

i dont blame you ive posted at least 4 questions that were easily answered in one post
