<title>phys_ballsocket</title> # phys_ballsocket A constraint that keeps the position of two objects fixed, relative to the constraint's origin. It does not affect rotation. ### Keyvalues + Name (`targetname`) > The name that other entities refer to this entity by. + Tags (`tags`) > A list of general purpose tags for this entity, for interactions with other entities such as triggers. + Friction (`friction`) > Resistance/friction in the constraint. + Entity 1 (`attach1`) > The source entity to constrain from. Leave empty to constrain from the world entity. + Entity 2 (`attach2`) > The entity we constrain to. ⤶ + Enable Collision (`enablecollision`) ⤶ > Constraints disable collision between the attached entities. In some rare cases we want to enable this collision. ⤶ + Impulse Limit to Break (kg) (`forcelimit`) > The amount of impulse an impact must apply to the constraint to break it. A way of calculating this is to set it to the mass of an object that would break this constraint if it were resting on the constrainted objects. + Angular Impulse Limit to Break (kg* distance) (`torquelimit`) > The amount of angular impulse required to break the constraint. A way of calculating this is to multiply any reference mass by the resting distance (from the center of mass of the object) needed to break the constraint. + Play Sound on Break (`breaksound`) > A sound played when the constraint is broken. ⤶ ### Flags⤶ ⤶ + Enable Collision (`enablecollision`) ⤶ > Constraints disable collision between the attached entities.
