it looks like the mu is not on a length orientated object any more
With print @.location ( output is the console) I want to find out where the triggering mu is located.
@ The strange thing is that no MU passes this sensor, but the function on this sensor is triggered.
I don't think so
The result of the print is：
Error in method '..Models.Frame.TwoLaneTrack2111.OnSensor5' in line 16: You can only stop/continue on a length-oriented object.
..Models.Frame.EventController: Events processed = 26139, Real-time factor = 621.4, CPU Time = 0.78s, Events/CPU second = 33511.32
