Can you help me?

How can i change the rpg maker vx battling system into like ff7 battling system?

Some help me I'm a beginner

I'm assuming you want a sideview battle system? Or are you asking for a Materia system. Either way, it would take a script to do. There are already a couple of sideview systems available (just check out the script submission area), but I'm not sure of a Materia system. If there's not, then you can request one in Script Request.

There is a Materia system for VX

maybe you could get it ported to ACE.
As for the side view I would say either use victor sant's side view for it uses holder's, regular sprites, and kaduki for ACE.

Or you can use the ACE version of Tankentai's SideView Battle System. The in game play is in English,but the script text is in Japanese. So it is hard to customize. Although ebonyazrael is translating the text to English, but please don't bother her about it bercause she is studying for exams right now I believe.
