【问题描述】:
我正在用 Visual C# 创建我的第一个非控制台游戏。 我有一个播放器是图片框,障碍物也是图片框。 现在,当我在随机位置创建障碍物(图片框)时,我想检查它是否已经接触到其他障碍物。
这是我现在拥有的:
Picturebox obstacles = new Picturebox[20];
for (int i = 0; i < obstacles.Length; i++)
{
DateTime date = DateTime.Now;
Random randomNumber = new Random(date.Second * (date.Minute / 2) ^ 2 + date.Hour * 123 + (i ^ 9 + i / 2));
obstacles[i] = new PictureBox();
obstacles[i].Image = Properties.Resources.es;
obstacles[i].Size = new Size(25, 50);
obstacles[i].Location = new Point(randomNumber.Next(640 - obstacles[i].Image.Width), randomNumber.Next(topBar.Height, 480 - obstacles[i].Image.Height));
if (IsTouching(obstacles[i], player))
{
i--;
}
else
{
bool tmp = true;
for (int j = 0; j < obstacles.Length; j++)
{
if (obstacles[j] != null && j != i)
{
if (IsTouching(obstacles[j], obstacles[i]))
{
tmp = false;
break;
}
}
}
if (tmp)
{
Controls.Add(obstacles[i]);
}
else
{
i--;
}
}
}
这就是我的方式,但我知道它不是很有效,所以任何更好的想法,因为创建这些障碍需要一段时间(约 5 秒)。 这是我的 IsTouching 方法,也有点烂,有人有更好的想法吗?
private bool IsTouching(PictureBox obj1, PictureBox obj2)
{
Point[] obj1Points = new Point[(obj1.Width * obj1.Height) - ((obj1.Width - 2) * (obj1.Height - 2))];
int count = 0;
for (int x = obj1.Left + 1; x < obj1.Left + obj1.Width - 1; x++)
{
obj1Points[count] = new Point(x, obj1.Top);
obj1Points[count + 1] = new Point(x, obj1.Top + obj1.Height);
count += 2;
}
for (int y = obj1.Top; y < obj1.Top + obj1.Height; y++)
{
obj1Points[count] = new Point(obj1.Left, y);
obj1Points[count + 1] = new Point(obj1.Left + obj1.Width, y);
count += 2;
}
Point[] obj2Points = new Point[(obj2.Width * obj2.Height) - ((obj2.Width - 2) * (obj2.Height - 2))];
count = 0;
for (int x = obj2.Left + 1; x < obj2.Left + obj2.Width - 1; x++)
{
obj2Points[count] = new Point(x, obj2.Top);
obj2Points[count + 1] = new Point(x, obj2.Top + obj2.Height);
count += 2;
}
for (int y = obj2.Top; y < obj2.Top + obj2.Height; y++)
{
obj2Points[count] = new Point(obj2.Left, y);
obj2Points[count + 1] = new Point(obj2.Left + obj2.Width, y);
count += 2;
}
for (int obj2Point = 0; obj2Point < obj2Points.Length; obj2Point++)
{
for (int obj1Point = 0; obj1Point < obj1Points.Length; obj1Point++)
{
if (obj2Points[obj2Point].X == obj1Points[obj1Point].X && obj2Points[obj2Point].Y == obj1Points[obj1Point].Y)
{
return true;
}
}
}
return false;
}
它的作用:检查给定的两个参数边缘是否相互接触。所以基本上只是一个碰撞检测,任何人都有任何想法,因为我对这个东西有点陌生?
