@vaidas
Thank you and I will do my best for the next update!
@Xray
Yes, you are right with the orbits but I implemented the average distances for circular orbits, because the true elliptic orbits would be very complex and hard to implement - BUT perhaps I will do that correction for an update! =)
O.O This greatful scene works with almost no lag. Even the trees move in the wind. Every little thing - the well of water and the hidden respawn of pinewood, the complete saw mechanism is almost unbelievable. I am impressed to see, what is possible in Algodoo even without scripts (with the exception of respawn-scripting) if you are smart (and you are very smart!).
I would give you 100 of 10 but it is impossible...
Go on, show all of us - even the marble race kids - what Algodoo is made for.
