Ladders and Vines

Ladder block (left) and Vine block (right)

Hitbox

Visually, ladders seem to be a flat texture 1 pixel away from the voxel's side.

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

Vines are intangible, but their properties are identical to ladders

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

Properties

Entities are affected by ladders if they coordinates are within the red marks.

While inside the effect hitbox, Movement mechanics are affected in two ways:

• Colliding with any wall will make the Player climb at a constant rate of 0.1176 b/t
• Sneaking will prevent the Player from falling.

Ladders and vines also have a few effects on Movement:

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