line to movieclip collision

Dear Kglad 

I have done some researching and have come up with a solution by adapting  a JS code online to animate for most of my problems ,the only sticking point now is cant get the movie clip on stage and the create guided path does not seem to work for the created circle. The movie clip in the library wil alsol not allow me to give it a linkage name (Adobe animate 2023) .The motion guide can work if put static numbers but not it seems with variables.Would like to post FLA but seems to be no way to do that.

Red point, is point of intercection

purple is object to place on path.

Best Regards

Peter
