I want to have it so the player runs on a small rubber circle bolted to the wall, and whichever way he runs on it, it rotates another circle in the stage. I've got the running circle working fine, but how I get it to spin the other circle I don't know. This image might help you understand: http://i43.tinypic.com/2jaaoia.png Any ideas? By the way, I want running on the small wheel to only turn the larger one a bit, not one full revolvation each time the smaller one turns 360 degrees. IT also needs to turn the way the smaller one is turning.

Keys and motor bolts...

Mind explaining further?

Lol. So of my understanding, you've got the sackboy running on the wheel part sorted out... Right? Well on a part (On the edge) of that wheel, attach a magnetic key. Next to the wheel, on a different material, attach a magnetic key switch and set it to turning on everytime the key is near it. But makesure the keyswitch is turned on when the key is next to the key switch, not when it is on the other side of the wheel... Then attach the key switch to whatever is going to make the other wheel spin (like I said a motor bolt) and it should work out perfectly...

you could create gears such as these http://www.s9000.com.br/S9Demo/images/engrenagem01.jpg They are easy to make and look cool but you can always hide them if you don't want it to be seen.

I want the big wheel to spin the direction the one you run on is spinning, so the keys wouldn't work in this case... EDIT: Those gears would be a good idea, it's just the getting them to work would be hard for me. I'll go for the gears though, unless somebody has an easier idea? Thanks Morri.

I want the big wheel to spin the direction the one you run on is spinning just add a gear between the one you are running and the one you want it to spin, the first and third will spin in the same direction.

So you want something like a "hamster wheel" where you running on it essentially powers on another gear or wheel? Am I understanding correctly?

Yep, that's pretty much spot on. Anyway, I'll go for the gear idea. Thanks again, Morri.

At a first thought, I would use Morris suggestion. This would be a good opportunity to try the cogwheels in the objects section, assuming you got them in story mode. Glue your wheels to cogwheels and put other cogwheels inbetween to connect them. The only problem I see is that the weight of sackboy running on the wheel will probably not be enough to turn the cogs. A different way would be using sensors with very small radius to check if sackboy is running right or left (put them on the purple things in your diagram) and have the wheel turn in different directions using a motorbolt. To make the same motorbolt turn into different directions, I made a switch called "Direction Splitter". It's pretty simple, but I don't want to explain it here. You can get it in my level "Shiwa's Devices V2". This solution might also not work too well, depending on how precise the sensors work. The probably best working and most precise method I can think of is a little more complex.. The switches I mention here can all be found in my level. I recommend first going through my level and read the following explanation again, if you want to use this solution. Again, use sensors to check if sackboy is running right or left, by putting them on the purple circles in your graphic. This time, connect each sensor to a State Switch. Connect each output of the State switch to an Input of 2 different AND Gates, so that each AND Gate still has one free Input. Now put a lot of (you have to see how many you need) Magnetic Keys on the outside of the wheel, which sackboy runs on. Place one Magnetic Switch directly beneath the wheel, so it can sense the keys (Preferably only one at a time). Connect the Magnetic Switch to an Input Deleter, set it to one shot, and set the Input Deleter to about 0.5 seconds (You'll have to fine tune that later). Now connect the Input Deleter to the free Input of each AND Gate. Connect each AND Gate to a Direction Splitter and connect the Direction Splitter to the motorbolt of the grey wheel in you graphic. If you run on the wheel now, the keys will activate the one shot switch, which will make the wheel turn a little bit each time. Because there are many keys, they will activate the switch many times, so the wheel should keep turning. This solution is a bit like what TheArmedReaper suggested. But I don't think using only one key will work too well. Hope it helped, it's up to you what you want to use in the end.

Gosh, I'll have to try than next time. Thanks for taking your time to write all that out.

make sure to use the same size cog unless you want a difference in speeds. Remember: Powering a small Cog which turns a large cog means the large one will turn slower. And the opposite is true for the opposite.
