Well, only being able to spawn a single dante per level would make the setup a tad easier, but the script remains, for the most part, the same.
I think you should take the time to learn scripting, and if you can make an honest attempt at it, I'm willing to help you out with any troubles you have along the way.
Try to write the script yourself, and come back when you're not sure what to do, or if something's going wrong. Post your script here and we can help meld it into something functional.
That being said, the way I see this working, it would require weapon scripts, which seem to be bugged at the moment in PB. It may have to wait until those are fixed.
Unless someone else has an idea of how it could work without using weapon scripts, that is.
The one and only,
Only those who sow the seeds of their desires will reap their benefits later.
However, I have seeds of my own to tend to. I don't have time to be someone else's watering can.
