## Parameters

# Input ports

### On

Parameter ID: `DYNAMICS_INTERACTION_NODE_INPUT_ON`

Turns the Node’s effect on or off.

### Object

Parameter ID: `DYNAMICS_INTERACTION_NODE_INPUT_OBJECT`

Add Connectors or Springs here.

### Object Index

Parameter ID: `DYNAMICS_INTERACTION_NODE_INPUT_INDEX` · Range: [0..2147483647]

Internally, all Connectors/Spring in the Project are numbered. Use this input setting to access individual Connectors/Springs.

### Broken

Parameter ID: `DYNAMICS_INTERACTION_NODE_INPUT_BROKEN`

This mode can be used to break (enabled) or ,repair’ (activate option again) a Spring.

### Linear Plastic Elongation

Parameter ID: `SPRING_NODE_INPUT_LINEAR_PLASTIC_ELONGATION` · Range: [-∞..+∞m]

### Angular Plastic Elongation

Parameter ID: `SPRING_NODE_INPUT_ANGULAR_PLASTIC_ELONGATION` · Range: [-∞..+∞°]

Use these modes to define deformations along the length of a Spring (elongation) or for its rotation (angular).

# Output ports

### Count

Parameter ID: `DYNAMICS_INTERACTION_NODE_OUTPUT_COUNT` · Range: [-2147483648..2147483647]

If the **Object** field is empty and receives no data via the Input port, the total number of Connectors/Springs in the project will be displayed here.

### Broken

Parameter ID: `DYNAMICS_INTERACTION_NODE_OUTPUT_BROKEN`

The Boolean value defined here will depend on whether the Spring is operational 0 or broken 1.

### Object

Parameter ID: `DYNAMICS_INTERACTION_NODE_OUTPUT_OBJECT`

### Object A

Parameter ID: `DYNAMICS_INTERACTION_NODE_OUTPUT_OBJECT_A`

### Object B

Parameter ID: `DYNAMICS_INTERACTION_NODE_OUTPUT_OBJECT_B`

### Object Index A

Parameter ID: `DYNAMICS_INTERACTION_NODE_OUTPUT_INDEX_A` · Range: [-2147483648..2147483647]

### Object Index B

Parameter ID: `DYNAMICS_INTERACTION_NODE_OUTPUT_INDEX_B` · Range: [-2147483648..2147483647]

This is where the selected object as well as both objects or object indices (for cloned Springs) linked to the Connector/Spring will be attached.

### Tag A

Parameter ID: `DYNAMICS_INTERACTION_NODE_OUTPUT_TAG_A`

### Tag B

Parameter ID: `DYNAMICS_INTERACTION_NODE_OUTPUT_TAG_B`

The Dynamics Body tags of the objects linked to the Connector can be attached to these Output ports.

### Linear Plastic Elongation

Parameter ID: `SPRING_NODE_OUTPUT_LINEAR_PLASTIC_ELONGATION` · Range: [-∞..+∞m]

### Angular Plastic Elongation

Parameter ID: `SPRING_NODE_OUTPUT_ANGULAR_PLASTIC_ELONGATION` · Range: [-∞..+∞°]

Use these modes to define deformations along the length of a Spring (elongation) or for its rotation (angular).
