Unfortunately I cant port the same code. VX Ace uses their own version of Ruby. While MV uses their own version of java script. This makes it hard to port over scripts. Maybe I could find separate plugins for both of them however. Like the "Yanfly" plugin. Yanfly has one for ruby and Javascript, and I think they work the exact same, so I could just use both the ruby and Javascript. However, some plugins don't work the same.
It's also funny you mention that about the syringe, haha. I'm thinking of maybe changing the design, or making the name "electrical syringe," as in, the syringe can travel through your opponent with electricity. Idk, might just change the design.
