}

Context and adjustable pose for a first-person hand render.

Translation is in blocks and rotation is in degrees (pitch, yaw, roll). The renderer applies the transform before the ordinary hand and item poses.

Fields

player: u128

The UUID of the player whose hand is drawn.

player_entity_id: i32

The network id of that player.

hand: Hand

Which hand is drawn.

stack: Option<&'a ItemStack>

The stack shown in the hand; None for the empty main-hand arm.

partial: f32

The fraction of the current tick elapsed, 0 to 1.

interpolated_pitch: f32

The player pitch interpolated for this frame, in degrees.

swing: f32

The swing progress, 0 to 1.

equip: f32

The inverse equip height, including the swap animation scale.

packed_light: u32

Vanilla packed light at the eyes (LightCoordsUtil.pack: block << 4 | sky << 20).

translation: [f32; 3]

A mod-set offset in blocks; applied before the hand is drawn.

rotation: [f32; 3]

A mod-set rotation as pitch, yaw and roll in degrees.

scale: f32

A mod-set uniform scale; 1 leaves the size alone.
