Simple Physics is a node that can have parameter assigned and it can perform physics in the way that are set on parameter.
On Simple Physics, these proprieties that can be edited:
Simple Physics Node to your node tree.Simple Physics Node.parameter. A 1D Parameter (-1..1) should work well enough. Arm the parameter and set points -1 and 1 with the object in the Simple Physics Node.parameter, drag it from the parameter list to the inspector “(Unassigned)” box, while the Simple Physics Node is selected.Simple Physics Node is connected to.
