Quick Animations do SephirothSpawn

Quick Animations é um script para o RPG Maker XP criado pelo SephirothSpawn que foi desenvolvido para ser como um reprodutor de animações estilo GIF num projeto ou jogo deste maker.

Como imagens neste formato (.GIF) não são reproduzidas no RMXP (sem API), este script ou usa uma série de imagens em um diretório numerado ou em uma imagem com múltiplos frames usadas lado a lado.

Ou seja, o script não reproduz arquivos .GIF, mas emula o seu funcionamento.

Código do Script

# SephirothSpawn
# Version 2
# 2006-08-27
#------------------------------------------------------------------------------
# * Description :
#
#   This script was designed to act as a GIF animation player. Because GIF
#   images aren't actually able to play in RMXP (without API), this script
#   either uses a series of images in a directory numbered OR an animation
#   like image with multiple frames placed side by side.
#------------------------------------------------------------------------------
# * Instructions :
#
#   Place The Script Below the SDK and Above Main.
#
#   ** Setting Up Animation Type A **
#
#   <your_object> = Quick_Animation_A.new(directory, loop = true, 
#                                         frame_skip = 10, viewport = nil)
#
#     Directory : Folder in Game/Graphics/Pictures in which frames are 
#                 labeled 0 to X
#     Loop : If true, the object will repeat itself until disposed. If false,
#            after the object has played all frames, will self dispose.
#     Frame Skip : The Number of game frames to pass before the next frame is 
#                  displayed.
#     Viewport : Viewport Sprite will be placed on.
#
#   ** Setting Up Animation Type B **
#
#   <your_animation> = Quick_Animation_B.new(bitmap, frames, loop = true, 
#                                            frameskip = 10, viewport = nil)
#
#     Bitmap : Filename of image in Game/Graphics/Pictures Folder.
#     Frames : Number of frames of animation.
#     Loop : If true, the object will repeat itself until disposed. If false,
#            after the object has played all frames, will self dispose.
#     Frame Skip : The Number of game frames to pass before the next frame is 
#                  displayed.
#     Viewport : Viewport Sprite will be placed on.
#
#  ** NOTE: Object must have the update method called to advanced frames.
#     It is advised to update will the unless self.disposed? trailing
#     in the event the object self disposed (loop = false).
