RESOLVIDO!(Dúvida rmxp) script gif player

KAI GAMES · 05 de Janeiro de 2023

olá!, recentemente encontrei um script de gif player para RMXP.... créditos a Shakugan no Shana pela criação:

Ruby:

=begin

  脚本：【怨念产物 - GIF图片播放】
 
  功能：在游戏中播放GIF图片 ※ 表情优先。
 
  说明: 使用步骤：
 
        1、使用 @gs = GIFSprite.new([viewport,[x,[,y,[loop_counts]]]])
           创建GIF图片对象；
       
        2、然后使用 @gs.bitmap = "gif_filename" ※ 包含文件夹路径；
     
        3、可以 @gs.loop_counts = n
       
           设置循环次数，-1表示无限循环(默认的)，0就释放图片。
       
        4、@gs.x = x,@gs.y = y,@gs.z = z 等设置各种坐标值。
 
  补充：1、由于考虑的效率问题，提供了生成临时文件技术，即第一运行之后以后每次运
 
        行会直接读取临时文件生成对象，可以使用 GIFSprite.TmpFileclear 清空临时
     
        文件。
     
        2、可以使用 GIFSprite.pre_load(filename_arr) 数组预加载一组图片。

script encontrado em:
https://templorpgmakerbr.forumeiros.com/t1048-gif-player

Este script permite a leitura de um dos muitos formatos que o maker não lê: o .gif, podendo ser animado ou não.
é necessário ter uma pasta chamada "GIF" no projeto e depois chamá-los para reproduizir via chamada de script

porém, o que era de se esperar, é extremamente lento para carregar em alguns casos.... o que me fez ter a seguinte dúvida. ...
É possível pré-carregar todos os gifs da pasta "GIF" antes de iniciar o jogo para poder exibi-los posteriormente depois?

tipo uma tela de loading antes da tela inicial pra poder pré recarregar tudo antes

....não sei dizer se resolveria o problema...o que vocês acham?

desde já agradeço

EDIT

RESOLVIDO!

A solução foi encontar um script que usa úma unica picture como uma linha de sprite horizontal

O script é o Easy animated pictures V1.... créditos a lavendersiren e Coelocanth pela criação

Ruby:

#-------------------------------------- ---- -- -
#  Easy animated pictures v1
#  by lavendersiren and Coelocanth
#-------------------------------------- ---- -- -
# Where to put: between debug and main, most likely near the top of your script list.
# May have some incompatibilities with other scripts that modify how pictures work.
#
# How to use:
# 1. Turn your animation into a horizontal sprite strip.
# 2. Make sure the file name starts with an exclamation point,
# the number of frames, and an underscore. Put whatever you want right after.
#
# Example: !4_firetest.png
#
# 3. Then, just import it into the picture folder and use as usual!
#
# Terms of use:
# Can be used in any project, commercial or noncommercial, with proper credit.

a imagem precisa estar na pasta pictures pra funcionar
o nome do arquivo deve começar com um ponto de exclamação, o número de quadros e um sublinhado. e depois pode colocar o nome que quiser .

Exemplo : !4_firetest.png (sendo 4 o número de frames que contem na picture)
depois é só mostrar a picture normalmente por eventos

pra converter os gifs em uma única linha de sprite usei um software gratuito e bem leve chamado Avi4bmp

dá pra baixá-lo rapidamente no link:

Pelo menos aqui pra mim fazendo isso o lag diminuiu bastante então....

OBRIGADO A TODOS!

No campo da especulação é uma boa ideia, porém... não sei se o Maker XP tem suporte a isso.
Acho que a solução mais trabalhosa para a aumentar a eficiência dessa ideia seria desmembrar esses gifs e os animar de forma manual no comando "show picture". Você teria que usar com certa ponderação as gifs, mas mesmo assim é uma ideia... Se fosse para usar em algum tipo de menu ou sei lá que você quer usar os gifs, geralmente os scripts de Menu tem essas pictures animadas se movimentando!

Bem, vamos aguardar alguém ainda melhor que eu dar algumas sugestões.

KAI GAMES · 06 de Janeiro de 2023

entendo ,eu até poderia salvar quadro a quadro das imagens em uma pasta, mas o fato de ser um numero muito alto de quadros acho que seria inviável .... nesse caso seria mais interessante se desse pra chama-los todos de uma vez controlando a ordem e o tempo entre elas

é que realmente são muitos quadros, são quadros pra caramba

.....me lembro de ter visto um script que fazia isso a muitos anos atrás...não sei ao certo onde encontrá-lo de novo mas acredito que dessa maneira tbm resolveria o problema do lag.....
