Question

我正在建立一个大富翁游戏。到目前为止，我设置了一个包含游戏板和几个按钮的界面。我想在他们掷骰子后在一个空间上画两个玩家的位置。我在起跑区吸引了球员的位置。我想将他们的位置（表示为实心圆圈）移动到新位置。但我不知道这么做。具体来说，如何让PaintEventHandler知道需要发生新的Paint事件。以下是我的代码。

namespace Monopoly
{
    public partial class GameInterface : Form
    {
        // If the remainder of whichTurn is 0, player1's turn to play game 
        // Otherwise, player2's turn to play game
        private int whichTurn = 0;

        // Record the result of the dice rolled by players
        private int result;

        // 0 for beginning, 1 for playing
        private int state = 0;

        Game game = new Game();
        Player player1 = new Player("Player1");
        Player player2 = new Player("Player2");

        public GameInterface()
        {
            InitializeComponent(); 
        }

        private void panelBoard_Paint(object sender, PaintEventArgs e)
        {
            if(state == 0)
            {
                DrawPlayerAtStart(e);
            } else if(state == 1)
            {
                DrawMovement(e);
            }           
        }

        // Draw two circles at the beginning area
        private void DrawPlayerAtStart(PaintEventArgs e)
        {
            // Draw first player's position
            SolidBrush firca_dis = new SolidBrush(Color.FromArgb(192, 0, 192));
            Rectangle recPlayer1 = new Rectangle(600, 500, 20, 20); //Size and location of the Circle

            e.Graphics.FillEllipse(firca_dis, recPlayer1); //Draw a Circle and fill it
            e.Graphics.DrawEllipse(new Pen(firca_dis), recPlayer1);

            // Draw second player's position
            SolidBrush secca_dis = new SolidBrush(Color.FromArgb(17, 0,255));
            Rectangle recPlayer2 = new Rectangle(600, 540, 20, 20); //Size and location of the Circle

            e.Graphics.FillEllipse(secca_dis, recPlayer2); //Draw a Circle and fill it
            e.Graphics.DrawEllipse(new Pen(secca_dis), recPlayer2);

        }

        // Draw two circles after player rolled the dice
        private void DrawMovement(PaintEventArgs e)
        {
            SolidBrush firca_dis = new SolidBrush(Color.FromArgb(192, 0, 192));
            Rectangle recPlayer1 = new Rectangle(547, 520, 20, 20); //Size and location of the Circle

            e.Graphics.FillEllipse(firca_dis, recPlayer1); //Draw a Circle and fill it
            e.Graphics.DrawEllipse(new Pen(firca_dis), recPlayer1);

            // Draw second player's position
            SolidBrush secca_dis = new SolidBrush(Color.FromArgb(17, 0, 255));
            Rectangle recPlayer2 = new Rectangle(547, 550, 20, 20); //Size and location of the Circle

            e.Graphics.FillEllipse(secca_dis, recPlayer2); //Draw a Circle and fill it
            e.Graphics.DrawEllipse(new Pen(secca_dis), recPlayer2);
        }

        // Let player roll dice roll dice 
        private void rollDiceButton_Click(object sender, EventArgs e)
        {
            state = 1;
            if(whichTurn % 2 == 0)
            {
                result = player1.GetRollDiceResult();
                textBox1.AppendText("Player 1 rolled "+result + "\n");
            } else if(whichTurn % 2 == 1)
            {
                result = player2.GetRollDiceResult();
                textBox1.AppendText("Player 2 rolled " + result + "\n");
            }

        }
    }
}

Answer 1

移动＆＃34; recPlayer1＆＃34;和＆＃34; recPlayer2＆＃34;升级到班级，就像你已经完成了＆＃34; Player1＆＃34;和＆＃34; Player2＆＃34;。现在只需更改矩形的位置，然后调用panelBoard.Invalidate();使面板重新绘制，圆圈移动到新位置。

在新位置画一个圆圈
