对于非描述性标题,我很抱歉,但我不知道如何传达这些问题。对于初学者来说,JButton 不时地按照循环应该创建它们的相同顺序多次创建自己。我遇到的另一个问题是,当我使用 setLocation() 方法重新定位它们时,它会在我想要它们的位置创建新的 JButton,但也会将旧的 JButton 留在它们所在的位置。我不知道我是否只需要刷新图形或发生了什么。谢谢您的帮助。
数组 playerHand() 在 Player 类中定义,长度为 5。
public void paintComponent(java.awt.Graphics g){
setBackground(Color.GREEN);
// create a Graphics2D object from the graphics object for drawing shape
Graphics2D gr=(Graphics2D) g;
for(int x=0;x<Player.hand.size();x++){
Card c = Player.hand.get(x); //c = current element in array
c.XCenter = 30 + 140*x;
c.XCord = c.XCenter - 30;
c.YCord = 0;
//5 pixel thick pen
gr.setStroke(new java.awt.BasicStroke(3));
gr.setColor(Color.black); //sets pen color to black
gr.drawRect(c.XCord, c.YCord, c.cardWidth-1, c.cardHeight-1); //draws card outline
gr.setFont(new Font("Serif", Font.PLAIN, 18));
gr.drawString(c.name, c.XCord+10, c.YCord+20);
gr.drawString("Atk: ", c.XCord+10, c.YCord+60);
gr.drawString(""+c.attack, c.XCord+60, c.YCord+60);
gr.drawString("Def: ", c.XCord+10, c.YCord+80);
gr.drawString(""+c.defence, c.XCord+60, c.YCord+80);
gr.drawString("HP: ", c.XCord+10, c.YCord+100);
gr.drawString(""+c.health, c.XCord+60, c.YCord+100);
JButton button = new JButton(c.name);
button.setSize(c.cardWidth, c.cardHeight);
//button.setLocation(c.XCord, c.YCord);
this.add(button);
repaint();
}
} //end of paintComponent
