Struct TreasureChestLid 

pub struct TreasureChestLid {
    pub rope: RopeChain,
    pub is_open: bool,
    pub angle: f32,
    pub target_angle: f32,
    pub hinge_pos: Vec3,
    pub lid_length: f32,
}

A simple hinge implemented as a two-segment rope. The hinge point is fixed, and the lid swings open when interacted with.

Fields

rope: RopeChain

is_open: bool

Whether the chest is open.

angle: f32

Angle of the lid in radians (0 = closed, ~PI/2 = open).

target_angle: f32

Target angle for the lid.

hinge_pos: Vec3

Hinge position.

lid_length: f32

Length of the lid.
