Member Data Documentation

◆ damping

float unravel::physics_material::damping {0.1f}

Tooltip: Normalized stiffness value. Represents the elasticity of the material. Higher values indicate stiffer materials. Coefficient of damping. Range: [0.0, 1.0].

Definition at line 49 of file physics_material.h.

◆ friction

float unravel::physics_material::friction {0.5}

Tooltip: Restitution represents the bounciness of the material. A value of 0.0 means no bounce (perfectly inelastic collision), while 1.0 means perfect bounce (perfectly elastic collision). Coefficient of friction. Range: [0.0, 1.0] (sometimes slightly above 1.0).

Definition at line 39 of file physics_material.h.

◆ friction_combine

combine_mode unravel::physics_material::friction_combine {combine_mode::average}

How to combine friction values.

Definition at line 55 of file physics_material.h.

◆ restitution

float unravel::physics_material::restitution {0}

Coefficient of restitution. Range: [0.0, 1.0].

Definition at line 34 of file physics_material.h.

◆ restitution_combine

combine_mode unravel::physics_material::restitution_combine {combine_mode::average}

How to combine restitution values.

Tooltip: Coefficient of damping. Represents the material's resistance to motion. Higher values result in more energy loss.

Definition at line 53 of file physics_material.h.

◆ stiffness

float unravel::physics_material::stiffness {0.5}

Tooltip: Friction represents the resistance to sliding motion. A value of 0.0 means no friction (perfectly slippery), while values around 1.0 represent typical real-world friction. Values slightly above 1.0 can simulate very high friction surfaces but should be used cautiously. Normalized stiffness value. Range: [0.0, 1.0].
