Hi All

I am completely new to python and python but was intrigued by the sample scripts. I am trying to learn how to integrate the 2 scripts above so that the Loco Selector box is called and that address is used in the back-and-forth script.

My logic is that I need to assign the back and forth script to the click event button in the loco selector box, but, I could do with some pointers of where to start...?

Many Thanks

Andrew

This is a modified back and forth script that includes opening a window to select a decoder address.

Thank you very much, Peter. I will not only use the script but also ?try to learn from it. I really appreciate it. Andrew

Hi, so I got around to trying this having first tried to work out what it was doing. The piece that I could not understand was how the throttle selection entered in the box gets passed to the throttle. I commented out sensors to start with as I haven't set them up yet and just wanted to understand what is happening. My IDE only deals with Python 3.6 so I updated the print statements to functions.

I then added additional self.status.text display lines and print comments to help me debug. My code is below. However, I cannot get past the selection box. I enter the number and press start and nothing else happens - I get my print messages in the script output box (code highlighted in BOLD but nothing else happens). Any help appreciated!

A little update. I have now got this working (to a degree!). I rebooted and seems to have cleared some things. It seemed it also didn't like the delay functions. Replacing those with a straight number, and changing the print (delay)/1000 to print (delay/1000) has got ?it working, so I am learning!
