This is a forum where volunteers help you, not a forum you pay to enter in order to get help. Yeah, we have to be helpfull to you but ever heard about "Give a fish to a man and you will feed him for a day. Teach him how to fish and you will feed him for a lifetime." or if you prefer "What's the point of having good grades if you always ask teachers questions and only do what he ask? In a real-life new situation, you won't always have him help you".
So if you can't even find something a simple as a acronym, if won't get anywhere in RMXP.
There are tons of them over here. In any case "Because it looks cool" is not a synonym of "Because it will be good in my game". Imagine if everyone on this forum made a fan game of a final fantasy (a game wich kicks ass). I wouldn't even be here.
So...every (or almost) post in this thread asked you to give you more description because or else we can't help. You still haven't said anything, only why you want it which helps everyone.
Scripts can collide between them, but there is no such thing as my scripts don't work with SDK. 1/10 of their script dosen't work with one of yours. The whole SDK falls. From how you say things its exactly that case.
I never played X-2 but i know one things and its that it is made by professional programmers that i wouldn't understand a single line of code (and im quite good), and is a 3d many-month project. Why don't you ask someone to make ff13's battle system while you are at it (i would pay high just to try it out).
So, as a final quote : "The magic though dosen't exist. The world will not act like you wish to. Work for yourself (use the search bar), for we won't work for you (guess what you want precisly, the only details we got wasen't from you)."
