Create Aeronautics: Landing Legs

Adaptive landing legs for Create Aeronautics Ships. Land on uneven ground and stay level.

What it does

Put a Leg Mount on your Ship's hull and fit a Limb into it. That makes a Leg. Each Leg reaches down to the ground on its own, so the deck stays level on slopes, steps and holes. Simple Legs work by themselves. Hydraulic Legs are run by a Leg Controller, which sets the Ride Height and folds the Legs up for flight.

Features

• Leveling: every Leg picks its own Reach, so the Ship sits level on uneven ground.
• Foot grip: Feet hold like rubber pads, so a parked Ship does not slide off a slope.
• Crouch: while one Foot is still looking for ground, the other Legs lower the Ship together so it does not tip.
• Overreach: if the ground is too uneven, the Legs stretch to the max and the Ship tilts toward the low side.
• Two Leg types: Simple Legs (no power, no setup) and Hydraulic Legs (powered, adjustable).
• Leg Controller: sets Ride Height, links up to 8 Hydraulic Legs, Gear Up / Gear Down with redstone.
• Softening: a redstone signal on top of a Hydraulic Leg makes it softer, for example to kneel a parked Ship for loading.
• Bumpers: a Leg Mount facing sideways or up acts as a spring against ground it meets.
• Three Limbs: Short, Long and Heavy, each with its own Reach and Stiffness. Any item with the legworks:limb data component is a Limb too.

Quick start

1. Craft a Simple Leg Mount (or a Hydraulic Leg Mount) and a Limb.
2. Place the Mount on the hull facing down, right-click it with the Limb.
3. Assemble the Ship as usual. Simple Legs are done.
4. For Hydraulic Legs: place a Leg Controller on the Ship, sneak-click it with a Leg Controller item, click each Hydraulic Mount to link.
5. Power each Hydraulic Mount through its shaft. Scroll the Controller's value box for Ride Height. Redstone on the Controller = Gear Up.

Ponder (hold W over an item) shows all of this step by step.

Compatibility

• Ponder scenes for every block.
• Engineer's Goggles: Reach, load, Stiffness, power and warnings on every Leg.
• Jade and JEI (optional): status overlay, recipes, a "Leg Fitting" category and info pages.
• Create Display Link: Leg Controller and Leg Mounts are Display Link sources.

Requirements

Install on both client and server.

Known limitations

• No special landing mode yet: drops of more than about 20 blocks can tip the Ship over.
• Limbs cannot be inserted by Funnels. Fit them by hand.
• Pinned to Sable 2.0.x (uses mixins into Sable internals).
