  Perkenalan :
  Script ini nambahin effect "after image". Apa itu after image? Semacem efek
  ninggalin bekas gambar kalo bergerak.
  
  -----------------------------------------------------------------------------
  Cara penggunaan :
  Pasang script ini dibawah material namu diatas main
  Gunakan comment pada event untuk menentukan event tersebut ada afterimagenya
  atawa kaga seperti ini
  
  <afterimage>
  <aft opact: n>
  <aft rate: n>
  
  Keterangan :
  <afterimage>
  Tag ini menandakan bahwa event (dengan page saat) itu menggunakan afterimage
  
  <aft opact: n>
  Pergantian opacity tiap frame. Ganti n dengan angka. Semakin tinggi nilainya, 
  semakin cepat pula efek afterimage ilang
  
  <aft rate: n>
  Jarak antara after image satu dengan yang lain. Semakin gede, semakin jauh
  pula jaraknya
  
  -----------------------------------------------------------------------------
  Script call :
  Kamu juga bisa aktivasi afterimage melalui script call dari set move route.
  Caranya gini. Buka event > Set Move Route > Script :
  
  self.afterimage       = true / false
  self.afterimage_opac  = angka
  self.afterimage_rate  = angka
  
  ^
  Script call ini kegunaannya sama kek diatas
