Yes, I had the idea but until now, I couldn't think of a way to implement it. Sometimes ideas pour into my head, and other times the doors and windows are shut tight!
YOU SHOULD LEARN HOW TO PROPERLY MAKE A SCENE! Every one of your scenes has the same problem. The objects fall from the sky when the scene is started. That is not good!
faytree - You can celebrate anything you want to, as far as I'm concerned. Of course not everyone in the world celebrates Christmas, just as not everyone in the world reads the Koran. Lots of different people come here to Algobox to enjoy learning and using Algodoo, and that's what people should be doing while not judging each other because of our beliefs or faiths.
And no one had better call you a terrorist on this website because if they do, they will hear from me, and I will do whatever it takes to make sure that it doesn't happen again!
Chains and ropes are two of the more difficult items to work with in Algodoo. In your particular scene, the chain falls off the pulleys because the chain has no collision layer. Do the following things, and then your treadmill should work:
1. Select the chain and make it collision layer A.
2. With the chain still selected, change the chain values as follows:
Strength = 50000
Impulse Break Limit = 9999
3. Select the stone block and change its collision layer from A to B (this is needed so that the chain on collision layer A doesn't collide with the stone block.
After making those changes, your treadmill should work.
Why don't you upgrade to the latest version of Algodoo? It's free. Then your scenes will be able to be viewed by most other users. As it is, people using Algodoo cannot view your scenes made with Phun. Every time I load one of your scenes and then start Algodoo, the items in your scenes just fall straight down and continue falling into the abyss! PLEASE UPGRADE!
