Looping - Selected Nodes

Add this script to a "Batch Script" editor (F10) and execute it with Script > Run.

Find all objects in a selection of nodes and activate their "Active rigid body" dynamics feature:

# Get all selected nodes
nodeSelection = scene.getSelectedNodes()
 
# Loop through the nodes in the selection and filter out the objects
for entry in nodeSelection:
	if (entry.getType() == TYPE_OBJECT):
 
		# If an object was found activate its active rigid body state
		entry.setParameter("Dynamics", "Active rigid body")
