Ladder

The Ladder is a vertical climbable structure. It can be built free-standing on the ground, on Foundations or on Walls.

Construction
The Ladder's height can be adjusted between 2 and 20 meters in steps of 2 meters: 2/4/6 ... 18/20 meters. When building, the first click sets its starting position, then looking up or down sets the height, and the second click confirms the construction.

The handle at the top extends 1 meter higher than the climbable height.

Additional Ladder seggments can be attached each to another, snapping to either the top or the bottom, regardless if the ladder is free-standing or not. This makes it a very versatile tool for vertical traversal.

Diving
A ladder penetrating water surface, such as the sea level, can be used by engineers for diving into water. The downward key needs to be pressed very slowly to avoid being washed away. While in water, it is required to remain attached to the ladder or the engineer will begin floating to the surface.

This method can be used to obtain some collectibles located underwater.

History

 * Patch 0.3.6:
 * Introduced
 * Velocity check for all ladders was removed (it is now possible to attach onto them no matter how fast the engineer is moving/falling)

Other ladders
Several buildings also feature a ladder on their side. The following buildings do and are stackable:
 * Conveyor Pole Stackable
 * Pipeline Pole Stackable
 * Hyper Tube Support Stackable
 * Storage Container
 * Industrial Storage Container
 * Fluid Buffer
 * Industrial Fluid Buffer

Buildings that are non-stackable, but feature a tall ladder:
 * Lookout Tower
 * Radar Tower

Beside these, many factory buildings also have a ladder but are not stackable, such as Smelters and Miners.
