# * Minigame Susun Gambar
#-------------------------------------------------------------------------------
# Cara Pakai:
# - Copy script ini ke script editor, di atas Main
# - Panggil melalui event script:
#  $scene = Scene_SusunGambar.new(num_of_columns, num_of_rows, filename[, time])
#  num_of_columns = jumlah kolom yang diinginkan
#  num_of_rows    = jumlah baris yang diinginkan
#  filename      = nama file yang akan dijadikan gambar dari puzzle
#                    (file boleh berukuran bebas, tapi sebaiknya jangan melebihi
#                    544 x 416, karena kacau ntar . Dan file gambar harus
#                    disimpan di folder Graphics/Pictures)
#  time          = batas waktu dalam detik. Kosongkan bila tidak ingin
#                    memiliki waktu
# - Setelah permainan selesai, switch yang telah diset di bawah akan menjadi
#  ON bila menang, dan OFF bila kalah, kemudian variabel yg telah diset di bawah
#  akan berisi sisa waktu ketika menyelesaikan permainan.
#-------------------------------------------------------------------------------
# Term Of Use:
# - Terserah anda script ini mau diapain, dan tidak credit juga tidak apa-apa,
#  asalkan anda sopan dan menghargai sesama manusia
#-------------------------------------------------------------------------------
module SusunGambar

# RESULT_SWITCH_ID = ID switch untuk menyimpan hasil permainan
# REMAINING_TIME_ID = ID variabel untuk menyimpan sisa waktu ketika selesai
#-------------------------------------------------------------------------------
RESULT_SWITCH_ID = 1
REMAINING_TIME_ID = 1
#-------------------------------------------------------------------------------
# BLANK_COLOR = Warna kotak kosong
