Just use an ABS script that someone wrote. Like I said, Blizz-ABS already does stuff like this for RMXP. I'm not sure how many ABS's out there are written for VX/A though and if any of them are anywhere near as powerful.
You could try eventing it (people have done this in the 2k3 engine), but seeing as you are relatively new to this, I wouldn't suggest it.
