I've been trying to make a setpiece similar to somewhat like a bridge that flips open as seen here: http://ia.lbp.me/img/fl/ecae06cd5a118ddb5786b70918cdd853896589e4.jpg http://i2.lbp.me/img/fl/a92003d0ce3daa6176ddfd44168f5ea840218a79.jpg http://if.lbp.me/img/fl/d6fb4fbea84e89f8b8dadc9de32165698e87d236.jpg Could anyone give their take on how to do this?

If I were trying to remake this, (This is just me. There's probably much better ways.) I would bolt both of those pieces to a small piece of invisible holo. Then when you activate the bridge, you make the holo rise. Once it's all the way up, you activate a look at rotator and have it look at tags. Set labeled tags (left and right) in the correct spaces so the bridge angle is correct, and that should be it. I'm doing this off the top of my head. I have never tried this kind of thing before. So if it doesn't work, then I'm sorry. --Teh Nut

Do you want the bridge to appear then move? Do you want it to flip hard or just move at a steady pace? To get a moving bridge use a wobble bolt, with input set to forwards/backwards. If you want the bridge to appear then open and close, bolt it to some invisible holo with a 100% dampening tweaker attached. Capture and use it as an emitter's object and have it emit at the position you want. EDIT: Never mind I think I see what you want now. You want the bridge to kind of erupt out of the mound then fold down creating the platform. Bolt both parts of the bridge onto a solid bit of material (presumedly in the rear thin layer to get it to work). Attach this thin material to the ground using a piston. Now, when you want the bridge to activate have the piston extend, which will push the thin layer up which the bridge parts are bolted to, then they should fall down under their own weight (bolt strength set at 0). Looking at the bridge shape this is what should happen, if not you could force them to fall in the correct direction with numerous methods. You could attach a very weak mover to each side, or attach some invisible string or chains, or use a follower. Anything really.

Each bridge is likely held in a slot and simply pushed out by a piston that is set not to be stiff. The two curled pieces at the end act as a weight and make the bridge deploy in the correct direction. If you didn't want to use such a weight you could place a small lever on the end of the bridge inside the slot, with the slot itself having a small nook, so once the bridge was extended it would catch in the nook and deploy in the intended direction.

@Ayneh Nice analysis on the flipping bridge. @Xaif Thanks for the advice, though I tried pushing the thin wall up and the two beams of the bridge still didn't fall down to their proper place. Maybe I'll have to use the tag follower trick. EDIT: I placed a piston on the thin material and changed the corners of the bridge planks until the top was heavy enough so that the weight of it could be pushed down by gravity. No tag followers needed. Thanks for the advice guys.
