# phys_lengthconstraint
A constraint that preserves the distance between two entities. If the 'Keep Rigid' flag is set, think of it as a rod. If not, think of it as a virtual rope.
### 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.
⤶
+ Additional Length (`addlength`)
> Add (or subtract) this amount to the rest length of the rope.

+ Minimum Length (`minlength`)⤶
> If the constraint is not rigid, this is the minimum length it can be.
**Minimum Length (`minlength`)**⤶

+ Attached object 2 point (`attachpoint`)⤶

+ Keep Rigid (`KeepRigid`)⤶
> Keep the constraint rigid, as if it were a stick.

>* Keep the constraint rigid, as if it were a stick.⤶
+ Particle Effect (`ParticleEffect`)⤶
> If give, will spawn given particle as the rope. Particle's Control Point 1 will be set to the target entity, and will be removed if the constraint breaks.
⤶
+ 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.
