在Java中对图像序列进行动画处理 [英] Animating a Sequence of Images in java

问题描述

对不起，我的英语不好

大家好，我正在使用Java开发2D游戏，并且当要对图像序列进行动画处理时，只会加载最后一个图像&我不知道为什么我的代码看起来很逻辑这样，当我按下"Q"按钮时，那里通常会有一个动画.代码:

推荐答案

      for(int j=0;j<15;j++){
      still=attack[j];
  }

识别Q键时，您似乎只是在遍历动画帧(图像).要使动画可见，在每次更改动画帧之间都需要一段时间.

When identifying the Q key, you seem to just walk through the animation frames (images).For an animation to be visible, some time would have to pass between each change of an animation frame.

我建议您看一些示例和教程.就像在这里找到的太空侵略者"克隆: www.cokeandcode.com

I would suggest you take a look at some examples and tutorials. Like the Space Invaders clone found here: www.cokeandcode.com
