Joints

Each shape of the softbody is connected through joints.

The Joint parameters section contains options to either create PinJoint2D or DampedSpringJoint2D nodes that connect the RigidBody2D nodes togheter.

  • Joint Type: Sets the type of the joint to create. In case pin is selected, the PinJoint section can be updated also. Similar for the spring selection, the DampedSpringJoint section is taken into account.
  • Bias: This is a Godot specific property for joints.
  • Disable Collisions: Disables collisions between connected rigidbodies.
  • Break Distance Ratio: This is a ratio of when the joint should break. Putting it 0 disables breakable joints. Putting it at 1.5 for example means the joint should break if the two rigidbodies it has are more than 1.5x far away their original distance.
note

The break distance ratio is also multiplied by number of connections the rigidbody has. This means a rigidbody that is inside the softbody is less likely to break than a rigidbody from the edge of the shape.

Pin Joint Parameters​

The PinJoint parameters section contains parameters related to the pin joint:

  • Softness: If you increase this option, the softbody will be more loose.

Spring Joint Parameters​

The DampedSpringJoint parameters section contains parameters related to the spring joint:

  • Stiffness: Increase this property to make the softbody less squishy.
  • Damping: Increasing this will make the softbody reach the initial state faster, making it less loose.
  • Rest Length Ratio and Length Ratio: Control the rest length and length properties of the spring joint.
