=begin

  Perkenalan :
  Script ini berfungsi untuk mengganti aktivasi dash dengan cara double tap
  daripada dengan shift (kalo kamu mau mengalihfungsikan shift untuk hal lain)

  Cara penggunaan :
  Pasang dibawah material namun diatas main.
  Edit konfigurasinya bila perlu

  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.

# Sedikit konfigurasi
# =============================================================================

  DashDelay_Duration = 60
  # Atur maksimal jeda durasi waktu double tap dash disini (60 = satu detik)

  KeepShift = true
  # Tulis true jika kamu tetep pengen bisa dash dengan mencet shift

# =============================================================================
# Akhir dari konfigurasi
