Question

所以我正和朋友一起开发游戏引擎，目前我正在进行碰撞检测：

以下是移动和寻找检测的代码

    private void Timer_Tick(object sender, EventArgs e)
    {
        string[] text = GameCode.Text.Split(new string[] { System.Environment.NewLine }, StringSplitOptions.None);

        foreach (KeyValuePair<string, Panel> kvp in objects)
        {
            if (running)
            {
                if (text.Contains("Move " + kvp.Key + " Left"))
                {
                    Point loc = kvp.Value.Location;
                    loc.X = loc.X - 1;
                    kvp.Value.Location = loc;
                }

                if (text.Contains("Move " + kvp.Key + " Right"))
                {
                    Point loc = kvp.Value.Location;
                    loc.X = loc.X + 1;
                    kvp.Value.Location = loc;
                }

                if (text.Contains("Move " + kvp.Key + " Up"))
                {
                    Point loc = kvp.Value.Location;
                    loc.Y = loc.Y - 1;
                    kvp.Value.Location = loc;
                }

                if (text.Contains("Move " + kvp.Key + " Down"))
                {
                    Point loc = kvp.Value.Location;
                    loc.Y = loc.Y + 1;
                    kvp.Value.Location = loc;
                }

                if (text.Contains("Collide " + kvp.Key + " + " + kvp.Key))
                {
                    MessageBox.Show("Name1: " + kvp.Key + " + Name2: " + kvp.Key);
                }
            }
        }
        //Invalidate();
        DoubleBuffered = false;
    }

这是用于查找两个不同对象的代码，然后我将添加碰撞检测。

if (text.Contains("Collide " + kvp.Key + " + " + kvp.Key))
{
    MessageBox.Show("Name1: " + kvp.Key + " + Name2: " + kvp.Key);
}

但是当我输入时，碰撞obj1 + obj2 直到我将obj2更改为obj1然后它会弹出obj1 + obj1，但我想输入碰撞obj1 + obj2，然后一些如何检测它们之间的碰撞，但我不知道如何实现这个，我已经多次尝试了。

碰撞的逻辑是：

if (text.Contains("Collide " + kvp.Key + " + " + kvp.Key))
{
    if (kvp.Value.Bounds.IntersectWith(kvp.Value.Bounds))
    {
        //DO something
    }
}

正如评论中所提到的，循环代码内部正在寻找单个密钥，这就是为什么在键入Collide obj1 + obj2

时没有看到消息弹出窗口的原因

我建议将此逻辑移到foreach循环之外，并在每次移动时跟踪对象键。

private void Timer_Tick(object sender, EventArgs e)
{
    string[] text = GameCode.Text.Split(new string[] { System.Environment.NewLine }, StringSplitOptions.None);

    List<KeyValuePair<string, Panel>> movedObjects = new List<KeyValuePair<string, Panel>>();

    foreach (KeyValuePair<string, Panel> kvp in objects)
    {
        if (running)
        {
            if (text.Contains("Move " + kvp.Key + " Left"))
            {
                Point loc = kvp.Value.Location;
                loc.X = loc.X - 1;
                kvp.Value.Location = loc;

                movedObjects(kvp); 
            }

            if (text.Contains("Move " + kvp.Key + " Right"))
            {
                Point loc = kvp.Value.Location;
                loc.X = loc.X + 1;
                kvp.Value.Location = loc;
                movedObjects(kvp);
            }

            if (text.Contains("Move " + kvp.Key + " Up"))
            {
                Point loc = kvp.Value.Location;
                loc.Y = loc.Y - 1;
                kvp.Value.Location = loc;
                movedObjects(kvp.Key);
            }

            if (text.Contains("Move " + kvp.Key + " Down"))
            {
                Point loc = kvp.Value.Location;
                loc.Y = loc.Y + 1;
                kvp.Value.Location = loc;
                movedObjects(kvp);
            }
        }

        if(movedObjects.Count() > 1)  // change this logic accordingly when there more than two objects can move.
        {
             MessageBox.Show("Name1: " + movedObjects[0].Key + " + Name2: " + movedObjects[1].Key);

             if (movedObjects[0].Value.Bounds.IntersectWith(movedObjects[1].Value.Bounds))
             {
                 //DO something
             }
        }          
    }
    //Invalidate();
    DoubleBuffered = false;
}

如何通过textBox1.Contains
