I'm in need of some assistance. You see, in my time as a LBPer I've noticed the majortiy, if not all of vehicles, are powered by either a two-way, or three-way, switch. Being I wanted to do something a little different, I set out to create a hippy van. It came out really nice, black, with the day of the dead skeleton concept graphic on the side, and a bunch of sweet little stickers too. Then I made it three dimensional, adding little windowns so you could see your sackfolks inside the thing. And then. I ran into a problem. "Oh no!" I'm sure your all screaming. "What could it be!?" Well. I wanted to be different, and make a button opperated vehicle! At first, I had a little difficulty figuring out. And then, I realized, why not do it like they do with some of the older model cars. One button controls the on and off of the front wheel, which goes... well, forward. The other button controls the on and off of the back wheel, and thus, how the van goes backwards. Thinking myself a genius, I then set out to fix other problems with the button concept. Eventually making it so a sackperson could get on and off of one of the buttons, while still being held in place. That way, when the van got going fast, the sackperson wouldn't fall of the button, and could still hop on the other button. Now I was really celebrating my genuis. And then I actually tried to make it a-go-go. And It broke my fragile 'lil ego. See, the conclusion of my long winded story is that of my own tremedous failure. When you hit a button to go in one direction, for some reason, the other wheel refuses to move, which makes it grag. And well. You get a van that crawls around at slug speed. No fun at all. So, how can I fix this? Is there some way to make a wheel both a motor AND a loose rolling wheel? Any ideas or suggestions? Or is my doublebutton, front AND back wheel drive idea unworkable? PLEASE HELP MEEEEEEEEEEEE! WHAAAAAA! .... and sorry for making you listen to that huge story.

Ok I'm kinda unsure about what you're asking but just correct me if this doesn't answer your question. I think this could all be fixed with a flipflop switch (I think its called RS Latch but I think flip-flop is so much easier). If you connect this switch to the wheels they will always move but I'm sure there's something you could do to it to make it only move when your in the van I just haven't figured it out yet. Here's a little diagram: S|---X K X---| Legend: S=Mag switch set to directional K=Mag Key on a block of ice X=Metal attached to a piston (---=piston) Make each button set to directional and connect one to each piston. Connect the mag switch to the wheels. One piston moves the key away from the switch which should make the car go in reverse and the other piston moves the key toward the key making the car go forward. Hope this helps!

Hmmm... one of the first things that comes to mind is setting the strength lower, but then you'd lose horsepower in movement. How about this.. crude MS paint diagrams to follow... One way still is fueled by a 3-way switch. Basically, you have pistons that'll physically move 3-way switch one way or another depending on which button you step on... However, if you truly want a front AND rear drive vehicle with NO 3-way switch, I've determined a different solution: have both wheels as plain bolts (not motor or anything) and have a gear on each of their axles. The buttons could engage a mechanism that rotates a gear and pushes it into the gear on the appropriate axle, therefore moving the vehicle in that direction without drag and having both front and rear drive. Which is odd, but hey, different. Does this make any sense?

Those two ideas are way better than mine. I forgot all about the 3 way switch controlled by two pistons thing. That will definitely do the trick.

Thanks a million! Brnx... your idea. I would have never thought of that, but it's a little complex, but stable and workable, and it would be great for a 'how'd he make this work....' type thing. Foofles, your idea as just as good, and a little simpler. I think I may go with the gears attaching to standard bolts. It'd be fun to make and drive, and it would just look cool to have it run that way. Thanks! When I've completed the van, I'll post it here for you to see when I've completed the actual van, and the level when I finish it. (Which is a very large project of mine, and the first one I've really worked hard on. )

I don't know about the gears, but the Thraa-way does exacly what you would like to do. You could visit a level from a guy named 'osprey31' or 32 or something. He has a collection of prefab switches which includes a 3-way with winces instead of pistons. From my experience I can say that's the perfect solution. Ospreys version is really well-built too. You just have to attach the buttons to the two winches and you're set.

Alright, I'll be sure to check into that. A winch system owuld likely work much like the pully one. Thanks man. But I have a feeling I might have problems with the sackperson falling off the button...

But I have a feeling I might have problems with the sackperson falling off the button... Yeah, buttons are a bit slippery. You could also use button shaped pieces of grabbable material and attach grab-buttons to it.

I was thinking along the same lines. Or having the grabbable cork that pushes down and hits a button or prox switch. Or just adding little walls of polysterene as barriers.

The prox switch is the best option I think. I experimented a lot with making other stuff interact with buttons, but it's hard to make a reliable switch that way.

Yeah. For some reason it seems like the buttons applications are far limited compared to some of the other doodads in the poppit. But maybe that's why I'm draw to use them whenever possible....

I spy a secret fetish...forget I said that... Yeah. Well. Buttons are soooooo awesome. I think I'm going to make a level powered 100% by buttons. IT WILL BE AWESOME!
