Question

我正在制作一个2d平台游戏，其中包含几个“水平”的预制图像并随机将它们插入列表中。游戏永远不会结束，所以它会根据需要不断添加更多图像。

我在角色之间移动时遇到问题，因为当这个人到达一个图像的末尾时，它会抛出：

Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: Coordinate out of bounds!

但我的照片宽度为1000 x 600像素，并表示超出范围1000,413。

这是包含错误的部分的代码：

public void getActImg(){
    int tmp=0;
    for(int i=0;i<inUse.size();i++){
        tmp+=inUse.get(i).getWidth();
        System.out.println(imgPix);
        if(tmp/imgPix>=0){//int divide by width of all the pictures to find current img
            actImg=inUse.get(i);
            System.out.println(i);
            break;
        }
    }
}
public void fall(){
    if(posY+foot>getHeight()){
        die();
    }
    System.out.println((totDist+posX)%imgPix+","+(posY+foot));
    if(actImg.getImg().getRGB((totDist+posX)%imgPix,posY+foot)==Color.WHITE.getRGB()){
        posY+=vy;
        vy+=g;
        onGround=false;
    }
    else{
        onGround=true;
        if(vy>3){
            posY-=vy;
        }
        vy=0;
    }
}

我在互联网上搜索任何形式的帮助，但他们只讨论如何插入重力或使用箱子碰撞。我有引力但不明白箱子碰撞。这就是我使用颜色的原因。任何帮助将不胜感激

谢谢
