If it is unclear what effect an event has on a certain atom, you can trace relevant values or strings before and after the event. Make sure all you wish to trace is converted to a string, like:
Code: Select all
Trace(Concat([Test of row number:], string(Label([RowNr], i))))
Note: If lots of atoms will pass this certain event in a short time, slow down your runspeed. Otherwise it might become hard to stop your simulation and remove the message.
