Struct Transform 

pub struct Transform {
    pub translation: [f64; 3],
    pub left_rotation: [f64; 4],
    pub scale: [f64; 3],
    pub right_rotation: [f64; 4],
}

A display entity’s transformation (Display entity data, Minecraft Wiki): the rendered model is translation · left_rotation · scale · right_rotation applied to the unit cube.

Fields

translation: [f64; 3]

[x, y, z] translation, in blocks.

left_rotation: [f64; 4]

[x, y, z, w] quaternion applied after scale.

scale: [f64; 3]

[x, y, z] scale.

right_rotation: [f64; 4]

[x, y, z, w] quaternion applied before scale.

Implementations

impl Transform

pub fn faced(&self, facing: Facing) -> Transform

This transform turned by facing about the vertical axis through the mark: the translation rotated, the yaw composed before the left rotation. The model is Ryaw · T · L · S · R, which is T(Ryaw·t) · (Ryaw·L) · S · R — so the emitted entity stands at yaw 0 and no client fact about how a display’s own yaw composes with its transformation is relied on (spec-0082 §3.2).

pub fn turned(&self, a: f64) -> Transform

This transform turned by a radians about the vertical axis through the mark (right-handed about +y: +z turns toward +x) — what Self::faced does for a quarter turn, for any angle. An aimed assembly’s facings are turns of this kind (spec-0082 §5.7).

pub fn cells(&self) -> BTreeSet<[i32; 3]>

The cells this part’s box meets, relative to the mark’s cell: every cell the transformed unit cube overlaps with positive volume, judged exactly (a separating-axis test of the oriented box against the cell), not by the box’s axis-aligned hull — a part laid on a diagonal meets the cells along it, never the empty corners of its hull. The entity stands at the mark cell’s centre (x + 0.5, z + 0.5) on its floor (y).

pub fn meets_box(&self, lo: [f64; 3], hi: [f64; 3]) -> bool

Whether this part’s box overlaps the axis-aligned box lo..hi with positive volume, judged exactly. Coordinates are relative to the mark’s cell, which spans [0, 1] on every axis; the entity stands at its centre on its floor, as for Self::cells.
