maze1.java

这是本人自主开发的一个JAVA小游戏

    StringWidth = FM.stringWidth(EnglishTitle);//取得字符串EnglishTitle的Width
    StringHeight = Ascent + Descent;//取得字符串EnglishTitle的Height

    X = (width - StringWidth)/2;   //设置EnglishTitle开始处的X值
    Y = Y + Ascent;                //设置EnglishTitle开始处的Y值
    g.drawString(EnglishTitle,X,Y);

    ImageY = Y + Descent + 30;        //设置当前图像开始处的Y值
    g.drawImage(currentImage,ImageX+100,ImageY+100,100,100,Game);  //绘制当前的心形或星形图片 

    g.setFont(F3);                           //设置字体F3
    FM = g.getFontMetrics();            //取得FontMetrics类的实例
    Ascent = FM.getAscent();          //取得字符串的Ascent
    Descent = FM.getDescent();         //取得字符串的Descent
    StringWidth = FM.stringWidth(PressEnter);  //取得字符串的Width
    StringHeight = Ascent + Descent;      //取得字符串的Height

    X = (width - StringWidth)/2;         //设置字符串开始处的X值

    Y = ImageY+ImageHeight+Ascent+30+300;//设置字符串开始处的Y值

    if(showPressEnter) g.drawString(PressEnter,X,Y);//绘制PressEnter字符串
