Strategy

はしご系のジャンプをする際には、ジャンプの最後でスニークしてはしごを掴む必要がある。

スニークが遅すぎるとはしごを掴めず、早すぎるとはしごに届く前に速度が落ちてしまうので注意。

当たり判定

A ladder's collision box is 2 pixels wide.

Visually, ladders and vine appear as a flat texture, resting 1 pixel away from the wall it's placed against.

• In reality, ladders are 2 pixels wide (0.125b), 1 block high, and 1 block long.
• Vines, on the other hand, are intangible, meaning the Player can move right through them.
  

Properties

Entities are affected by ladders if their coordinates are within the red voxel.

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 affects 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

Changes (1.9+)

• In 1.9, ladders were changed to be larger by 1 pixel, making their new bounding box comparable to trapdoors (3px in width, or 0.1875b).
• In 1.14, the player can now climb ladders and vines by pressing jump, which makes ladder jumps feel easier.
