  Perkenalan :
  Mau bikin cuaca berangin? Bingung gimana caranya? Script ini bisa ngebantu
  kamu buat bikin cuaca serasa berangin di game

  Cara penggunaan :
  Pasang script ini dibawah material namun diatas main
  Edit konfigurasinya buat nentuin gambar partikel apa aja yg bakal kamu pake.
  Gambar harus ada di Graphics/system

  Script call :
  Untuk ngeset cuaca berangin, kamu cukup tuliskan script call :
  windy(key,x,y,jumlah,rotate)

  Dimana :
  - key     >> kunci untuk manggil file gambar (lihat konfigurasi)
  - x       >> kecepatan scroll horizontal
  - y       >> kecepatan scroll vertikal
  - jumlah  >> jumlah partikel yg ditampilkan
  - rotate  >> partikelnya diputer ngga? Isi dengan true atau false. Bisa
               diabaikan kalo ngga perlu (defaultnya : true).

  Untuk ngehapus, kamu tinggal nulis aja script call :
  erase_windy

  Terms of use :
  Credit gw, TheoAllen. Kalo semisal u bisa ngedit2 script gw trus jadi lebih
  keren, terserah. Ane bebasin. Asal ngga ngeklaim aja. Kalo semisal mau
  dipake buat komersil, jangan lupa, gw dibagi gratisannya.

  # Disini kamu nyatet gambar partikel apa aja yang akan kamu tampilkan dalam

  # "Key" nanti digunakan untuk pemanggilan dalam script call yg udah wa
