Damn. doing levels with as little (so mostly one) hydraulics as possible is just a form of art!

@acgoalie I think hydraulics can be done with just trial and error. But if you have trouble making arms turn by a lot(90° or so) with just one hydraulic, remember this:

1. Make a triangle with one Arm, one Hydraulic, and one Base.

2. Make the Base short — the roots of arm and hydraulic should be close together.

3. On the starting position, Arm must be going away from the hydraulics.

Basically, how it looks on my gif at the start.

I figured out the linkage but I still can't get hydraulic placement right how did you do that so nicely?

By any chance could you create like a Microsoft paint example of what you mean?

@acgoalie With a bit of geometry! First you take the starting point and the end point of a part of the bridge, and draw a line that divides the two exactly in half. Then make sure the root of those moving 'arms' are along that line.

How did you calculate this? Or was it trial and error?
