如何突出显示面板网格上的特定区域

Question

制作一个Panel填充表单，我想要一个字符（由pictureBox表示）来移动。当我点击角色的pictureBox时，我希望突出显示一个区域，表示该角色可以移动多远。

下面的图片是我目前管理的图片，但这不是我想要的。红色边框矩形表示pictureBox，而橙色矩形表示突出显示的区域。每个黑色边框矩形都是一个面板。

移动到对角线上的面板的角色应该消耗2个移动，这样如果角色有2个移动可用，则在点击pictureBox时，应突出显示下面的区域：

我理解为什么我的代码突出显示正方形而不是我想要的区域，但我不确定如何解决它。任何帮助，将不胜感激;下面是我写的代码。

        foreach (Panel pan in grid)
        {
            if (pan.Left <= (selectedCharacter.PictureBox.Left + (selectedCharacter.Movement * 80)) 
                && pan.Left >= (selectedCharacter.PictureBox.Left - (selectedCharacter.Movement * 80)))
            {
                if (pan.Top <= (selectedCharacter.PictureBox.Top + (selectedCharacter.Movement * 100)) 
                    && pan.Top >= (selectedCharacter.PictureBox.Top - (selectedCharacter.Movement * 100)))
                {
                        pan.BackColor = selectedCharacter.PlayerHighlight;
                }
            }
        }

以下是我提出的解决此问题的代码。如果您能看到更容易/不同的解决方法，请随意发表评论。

Panel[] highlightedMovement = new Panel[1]; //creates an array of panels to be highlighted
highlightedMovement[0] = characterBeingHighlighted.CurrentPanel; //adds the panel the character is currently on to the array

int z = 1;

//highlights panels adjecent to those already highlighted for as many iterations as the character's movement stat
for (int i = 0; i < characterBeingHighlighted.Movement; i++)
{
    foreach (Panel highlightPanel in highlightedMovement)
    {
        //goes through all panels on the grid and adds them to the array if they are adjacent to any already in the array.
        foreach (Panel gridPanel in grid)
        {
            //checks if the panel is adjacent to any already in the array
            if ((gridPanel.Top == (highlightPanel.Top + 100) && gridPanel.Left == highlightPanel.Left) ||
                (gridPanel.Top == (highlightPanel.Top - 100) && gridPanel.Left == highlightPanel.Left) ||
                (gridPanel.Left == (highlightPanel.Left + 80) && gridPanel.Top == highlightPanel.Top) ||
                (gridPanel.Left == (highlightPanel.Left - 80) && gridPanel.Top == highlightPanel.Top))
            {
                //adds it to the array but only if it isn't already in the array
                if (!highlightedMovement.Contains(gridPanel))
                {
                    Array.Resize(ref highlightedMovement, highlightedMovement.Length + 1);
                    highlightedMovement[z] = gridPanel;
                    z++;
                }
            }
        }
    }
}

//highlights all the panels in the array
foreach (Panel panel in highlightedMovement)
{
    panel.BackColor = characterBeingHighlighted.PlayerHighlight;
}
