PNG格式怎么会动呢,一张张做帧吧,又或者是用下面的GIF播放器,效果不明,用法不明,
在下只是收集了而已。
- =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。
