Enum WorldCoord 

pub enum WorldCoord {
    Double,
    Float {
        int_offset: i8,
        term: f32,
    },
}

How vanilla turns one bound of a collision box into an absolute world coordinate.

Most 1.8 blocks compute blockPos + localBound in double (WorldCoord::Double), which is exact. A few (cactus, cake, fence gate, soul sand, snow layer) do the addition in float: (float) (blockPos + int_offset) + term, widened to double. That rounds once |blockPos| is large (from 2^20 ≈ 1M blocks for 1/16 steps), and the rounded value is what vanilla collides with.

Variants

Double

f64::from(pos) + local (the matching Aabb bound).

Float

f64::from((pos + int_offset) as f32 + term): Java i2f, fadd, f2d.

Fields

int_offset: i8

Integer added to the block coordinate before the float conversion (pos.getX() + 1).

term: f32

float term added afterwards (negative for pos.getX() + 1 - f).
