It could be number of things! Something is wrong with your level, you made a mistake somewere. Go throw your game code or easier just start form scratch.

Well, I've built it from scratch anyway so I don't suppose there's a problem there.
About the code... where do I get it? I mean there are three bin files: the scenee one, the resrc one and the level...Which one should I post (or all)?

(thanks by the way for so promptly answering)

If I remember correctly, dMassCheck errors are given when you have geometry with static=false but that doesn't have a mass.

Thanks man. It was exactly that. I just needed to make them true instead of false.

I haven't got any geom with "static - false" but I still have this problem.

For some reason my problem came back...even after I've turned all static=false into static=true...

the oddest thing is that for some time I actually entered the level.(It had a lot of problems in it though but I still managed to enter)

How come is this possible?

Edit:

OK my bad! didn't read all of your instructions. I should't change the option to false but instead to give mass a number.

Now it works at least. thanks davidc

static=false (or if static is not set at all) means that it's dynamic geometry. It can move around within the level, it therefore needs a mass to determine how it reacts.

static=true is, so to speak, "fixed to the wall". It can't move at all, so it doesn't need a mass.

Martin33, you may not have static=false but do you have any geometries (or composite geometries) that you haven't set static on at all?

You should also avoid positioning geometries at the exact same position as forcefields, this seems to cause weird effects. Move them apart by a small amount instead.

Again about static and geometry...

I'm making a wheel that sould spin nailed to the backgound. If I turn static to false the wheel falls, if I turn it to true it doesn't spin any more.

What should I do?

Check out the scene of http://goofans.com/download/sample/rotating-planet for the simplest example of this.

only in compozitegeoms.
whole group of geometries has got static=true, but single geoms inside composite.

Maybe post your decrypted scene file here so we can see it?

level is not finished yet, but I can't continue doing it when i can't test if it works good.

geometry34-39 all need either static="true" or a mass.
