Initial placement

The initial shape is an eighth block positioned at the corner of the box in the direction the player is facing, as well as the vertical half of the box.

Manipulation

To manipulate the shape of a polymorph, interact with it while having the same block in hand. Each interaction adds an eighth block at the targeted spot if it's free.

Important Notes

• The outline boxes of blocks are always a full block in size, allowing them to be shaped into irregular forms that wouldn’t otherwise be possible. However, their large outline boxes can be obstructive, especially when interacting with nearby blocks. To minimize interference, avoid placing them near frequently used areas like doors or trapdoors. It’s also best to keep them out of tight spaces where combat with mobs might become difficult.

• Collision boxes don't always match the appearance of blocks. Currently, custom blocks are restricted to a single box-like shape. Standard shapes-such as full blocks, vertical slabs, horizontal slabs, posts, beams, and eighth blocks-have properly aligned hit boxes. However, irregular shapes must use the smallest possible bounding box that can fit their geometry. Unfortunately, this means stair-like shapes are forced to use full block-sized hit boxes, preventing them from functioning as true stairs.

• Fortunately, it is still possible to construct a functional staircase using beams.

• Polymorphs are interactive blocks that require players to crouch in order to place other blocks on them.

• Like slabs, polymorphs restrict different types from occupying the same block space.
