Ladders and Vines

Ladders are special blocks that allow entities to climb them.

Vines were added in Beta 1.8 and share the same properties.

Strategy
When attempting a ladder jump, you should always sneak at the end of your jump.

Don't sneak too late or you won't catch the ladder, but sneaking too early will slow your jump.

Hitbox
Visually, ladders seem to be a flat texture.

In reality, ladders are 2 pixels wide (0.125b), making them the thinnest block in the game (along with panes).

Vines are intangible, meaning the Player can move right through it.

In 1.9+, ladders are 1 pixel wider, making their new hitbox comparable to trapdoors (3px in width, or 0.1875b).

Properties
While the Player's coordinates are within a ladder's voxel, vertical movement is affected in two ways:


 * Colliding with any wall will make the Player climb at a constant rate of 0.1176 b/t (0.12 × 0.98)
 * Sneaking will prevent the Player from falling.

Ladders also have a few effects on horizontal Movement:


 * Horizontal speeds (X/Z) are capped at 0.15 b/t
 * Vertical speed (Y) has a lower bound of -0.15 b/t
