Physics Cable

A Physics Cable allows you to create a pliable, physics cable that can be anchored to nodes in the 3D world and used for simulating ropes, chains, pulleys, belts, wires, and cables.

The pins of a Physics Cable are listed as separate nodes in the Component Graph panel.

Properties

Name Description
Name Defines the name of the cable.
Thickness Defines the thickness of the cable.
Cable Length Defines the length of the cable.

If zero, the length of the cable is dynamic and based on other properties.
Collider Length Defines the size of the cable's collider relative to the cable's length.
Stiffness Defines the rigidity of the cable.

#Low
The cable is very flexible.

#Medium
The cable is fairly flexible.

#High
The cable is very rigid.
Node 1 Defines the node the first endpoint is attached to in 3D world.
Node 2 Defines the node the second endpoint is attached to in 3D world.
End Type 1 Defines the anchor type of the first endpoint.

#Free
The cable hangs freely while attached to Node 1.

#Rotating
The cable can swing back and forth or rotate while attached to Node 1.

#Fixed
The cable is securely anchored to Node 1.
End Type 2 Defines the anchor type of the second endpoint.

#Free
The cable hangs freely while attached to Node 2.

#Rotating
The cable can swing back and forth or rotate while attached to Node 2.

#Fixed
The cable is securely anchored to Node 2.
Total Length Factor Defines a factor for determining cable length.
Material Defines the material of the cable.
Advanced Turns on/off the display of advanced properties for the cable.

Advanced properties

Name Description
Spring Strength Defines the strength of the cable relative to the force applied when compressing/stretching the cable, for example its tensile strength.
Spring Damping Defines the damping of the cable, thereby affecting how bounciness of the cable.
Spring Tangential Strength Defines the tangential strength of the cable relative to force applied when contacting a surface.
Spring Tangential Damping Defines the tangential damping of the cable relative to force applied when contacting a surface.
Rendering Steps Defines the amount of steps for rendering the cable.
Collider Overlap Defines an accepted overlap of the cable's collider in relation to others.
Solver Iter Position Defines the solver iteration position of the cable.
Solver Iter Velocity Defines the solver iteration velocity of the cable.
Solver Iter Internal Defines the solver iteration internal setting of the cable.
Solver Iter External Defines the solver iteration external setting of the cable.
Solver Iter Projections Defines the solver iteration projections of the cable.
Solver Separation Limit Defines the separation limit of the solver for the cable.
Material Friction Static Defines the static friction of the cable's material.
Material Friction Dynamic Defines the dynamic friction of the cable's material.
Material Restitution Defines the restitution of the cable's material.
Material Density Defines the density of the cable's material.
Scene Id Defines the scene id of the cable, thereby allowing you to isolate the cable in different physics scenes/layers in the physics world.
Collision Group Defines the collision group of the cable, which can be used to filter collisions with the cable in physics world.
Center Position Centers the cable.
