Hello again.
I am trying to compile a script for Doc Brown to follow Marty McFly (you) in GTA SA. I knew this could be done in VC.
I succeeded in creating 2 scripts to spawn Doc Brown to follow. Here's the video.
And here's the download: http://goo.gl/aJjQTV
These scripts use Doc Brown as a different ped ID than the one Trance originally put them in. Please read the readme!
See you in the future...
