  ==================
  *) Perkenalan :
  ------------------
  Script ini ngebikin kamu nampilin dialog dalam balloon diatas karakter

  =======================
  *) Cara penggunaan :
  -----------------------
  Pasang dibawah material namun diatas main.
  Masukkan gambar untuk ballon pointer di Graphics/system. Dan jangan lupa
  dinamain "ballonpointer".

  Edit konfigurasinya dan ikuti aturan script call berikut

  =======================
  *) Script Calls :
  -----------------------
  - message.balloon
  Panggil script call seperti ini untuk membuat text ditampilkan dalam model
  balloon

  - message.normal
  Panggil script call seperti ini untuk mengembalikan message seperti biasa

  - message.subject = angka
  Panggil script call seperti ini untuk menentukan subject yang berbicara.
  Angka disana adalah event ID. Jika kamu memasukkan 0, maka yang akan
  berbicara adalah player. Jika event ID tidak ada, maka message akan
  berubah seperti biasa

  Atau jika kalian kerepotan untuk membuat script call, kalian bisa memakai tag
  <bm:x> pada kotak dimana x adalah event ID tersebut. Contoh

  <bm:1>Hai, apa kabar?

  =======================
  *) 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.
