Question

我想将文本部分CONTROLS放在右边而不是刚刚列出，我是一个新手，我使用的是发布Java游戏代码的网站的源代码。 Y坐标存在，但我似乎无法找到X坐标，这将帮助我定位文本部分。这是我的侧面板类的代码：

/**
 * The number of rows and columns in the preview window. Set to
 * 5 because we can show any piece with some sort of padding.
 */
private static final int TILE_COUNT = 5;

/**
 * The center x of the next piece preview box.
 */
private static final int SQUARE_CENTER_X = 130;

/**
 * The center y of the next piece preview box.
 */
private static final int SQUARE_CENTER_Y = 65;

/**
 * The size of the next piece preview box.
 */
private static final int SQUARE_SIZE = (TILE_SIZE * TILE_COUNT >> 1);

/**
 * The number of pixels used on a small insets (generally used for categories).
 */
private static final int SMALL_INSET = 20;

/**
 * The number of pixels used on a large insets.
 */
private static final int LARGE_INSET = 30;

/**
 * The y coordinate of the stats category.
 */
private static final int STATS_INSET = 100;

/**
 * The y coordinate of the controls category.
 */
private static final int CONTROLS_INSET = 175;

/**
 * The number of pixels to offset between each string.
 */
private static final int TEXT_STRIDE = 25;

/**
 * The small font.
 */
private static final Font SMALL_FONT = new Font("Arial", Font.BOLD, 11);

/**

 */
private static final Font LARGE_FONT = new Font("Arial", Font.BOLD, 13);

/**

private static final Color DRAW_COLOR = new Color(128, 192, 128);

    this.tetris = tetris;

    /*

    if(!tetris.isGameOver() && type != null) {
        /*

            }
        }
    }
