I need help making a sort of canon vehicle. A vehicle that has a canon, that can turn 360 degrees with a directional switch, and a button to help it shoot. I tried making this, but honestly it was a fail. I couldn't get it just right? Any of you guys would like to submit an idea? P.S. I do not want the canon interfering with the vehicle.

I made a Tank a few months ago which had a main cannon that turned through 360 so it could drive and shoot in both directions. Unfortunatey my data got corrupted and when I got it back my Tank had the 'Red blob of death' on it and I couldn't use it again. After that I got onto other projects and never made it again. All I did was make the Tank 1 thick layer with a thin layer back for the pod to attach to. Then I made the cannon 1 thick layer and attached that behind the pod and fastened it with a wobble bolt set to 180 degrees rotation positioned as central in the pod as possible and put a 3-way switch to that in the pod. Then it's a matter of tweaking the wobble bolt settings for angle and speed etc. As my tank was quite big ( a bit too big really ) i put the weapon switches on a piston too so that they moved to the other side of the pod with the cannon and had a camera at each end so the view moved also depending which way you were facing. You may not need to do that though if your vehicle is smaller. I hope that all makes sense and you find it helpful. BTW I like your avatar. Is that a drunken pirate moogle ? LOL

http://img151.imageshack.us/img151/3949/diagram.jpg I didn't really feel like opening up SolidWorks and creating a full-blown death machine, so I drew this in Paint. A quick overview: Basics: The red is the body, blue is the wheels. The yellow is basically a mast on which the cannon is placed. This mast can exist in either the flat layer in front of the car body, the flat layer behind the car body, or both. The green is a motor bolt, it will be attached to a three-way directional switch to keep things simple. This is also where the emitter will be placed. It is important to note that the emitter must be turning with the cannon or it will not fire correctly The orange is the actual cannon. It can be a solid block or a hollow block, it depends on how you want to do this. The emitter at the base is hooked up to a one-shot grab switch or button and the linear velocity should be fairly high (20-50, also depends on what you are firing). If the cannon is hollow, you can shoot the projectile from the base of the cannon. If not, you'll be shooting from the front, which won't look as nice. Any questions?

how many layers are you restricting this to?

Any questions? How are the wheels attached?

How are the wheels attached? The wheels can be flat or take up an additional layer, and are attached with motor bolts.
