Question

我遇到阻止移动的问题我已经在Blocking Movement On Collision上阅读了问题但我对自己的问题一无所知。如果你能给我逻辑，我会尽力解决自己的问题。我希望你能帮帮我这是我的玩家类更新

：编辑：感谢Kai Hartmann的回复我的问题是2D图形，我想知道如何在object1与object2碰撞时停止移动

public void Update(GameTime gameTime)
{
    // Ani Test
    up_ani.Update(gameTime);
    down_ani.Update(gameTime);
    left_ani.Update(gameTime);
    right_ani.Update(gameTime);

    position += velocity;

    if (Keyboard.GetState().IsKeyDown(key.MoveUp) && prevState.IsKeyUp(key.MoveDown) && prevState.IsKeyUp(key.MoveRight) && prevState.IsKeyUp(key.MoveLeft))
    {
        currentFace = FacePosition.Up;
        velocity.Y = -3;
    }
    else if (Keyboard.GetState().IsKeyDown(key.MoveDown) && prevState.IsKeyUp(key.MoveUp) && prevState.IsKeyUp(key.MoveRight) && prevState.IsKeyUp(key.MoveLeft))
    {
        currentFace = FacePosition.Down;
        velocity.Y = 3;
    }
    else if (Keyboard.GetState().IsKeyDown(key.MoveRight) && prevState.IsKeyUp(key.MoveDown) && prevState.IsKeyUp(key.MoveUp) && prevState.IsKeyUp(key.MoveLeft))
    {
        currentFace = FacePosition.Right;
        velocity.X = 3;
    }
    else if (Keyboard.GetState().IsKeyDown(key.MoveLeft) && prevState.IsKeyUp(key.MoveDown) && prevState.IsKeyUp(key.MoveRight) && prevState.IsKeyUp(key.MoveUp))
    {
        currentFace = FacePosition.Left;
        velocity.X = -3;
    }
    else
    {
        //currentFace = FacePosition.Down;
        velocity = Vector2.Zero;
    }

    prevState = Keyboard.GetState();
}

这是我的碰撞

public void IntersectWithScore(Vector2 vector1, Vector2 vector2, Texture2D object1, Texture2D object2, int doSomethingToScore, bool isIncrease)
{
    if (vector1.X + object1.Width &lt; vector2.X || vector1.X &gt; vector2.X + object2.Width ||
    vector1.Y + object1.Height &lt; vector2.Y || vector1.Y &gt; vector2.Y + object2.Height)
    {

    }
    else
    {
        player1.Velocity = Vector2.Zero;
    }
}

就我而言，不需要碰撞检查方法:)我已经很快写了这段代码，但应该可以正常工作吗？（ish）。我假设你想要检查某些东西是否在玩家的方式中并且还假设有多个对象可能在你的玩家中，所以为了做到这一点我建议为“Solid”对象制作一个类并给它位置，宽度和高度。然后列出这个类的列表以包含多个“实体”对象。

// collidable object's Class name = SolidBlock
SolidBlock newSolidBlock;
List<SolidBlock> solidBlocksList = new List<SolidBlock>();

// This will create 10 'solid' objects and adds them all to a list
// This would preferably go in the Load() function so you can set the positions of
// the blocks after creating them (after the loop)
int i = 0;
while (i < 10)
{
    newSolidBlock = new SolidBlock(Vector2, position) // Assuming width and height 
                                                      // are set within class
    solidBlocksList.Add(newSolidBlock);
    i++;
}

// It doesn't matter how you create them, the important lines here are the creation of a
// newSolidBlock and then the line adding it to the list of blocks.

solidBlocksList[0].position = new Vector (20, 50); // < for example this is how you would set
                                                   // a block's position.

然后在你的玩家更新功能中，你可以参考这个对象列表。

// Input a list of the objects you want your player to collide with
// this is a list in case you have multiple object2s you want to check 
// for collision.
// An Object2 should have a position, height, and width, yes?

public void Update(GameTime gameTime, List<Object2> object2List)
{
    // Ani Test
    up_ani.Update(gameTime);
    down_ani.Update(gameTime);
    left_ani.Update(gameTime);
    right_ani.Update(gameTime);

    position += velocity;

    if (Keyboard.GetState().IsKeyDown(key.MoveUp) && prevState.IsKeyUp(key.MoveDown) &&      prevState.IsKeyUp(key.MoveRight) && prevState.IsKeyUp(key.MoveLeft))
    {
        foreach (Object2 o in object2List)
        {
            if (position.Y <= o.position.Y + o.height)
            {
                velocity.Y = 0;
            }
            else
            {
                velocity.Y = -3;
            }
        } 
        currentFace = FacePosition.Up;
    }
    else if (Keyboard.GetState().IsKeyDown(key.MoveDown) && prevState.IsKeyUp(key.MoveUp) &&     prevState.IsKeyUp(key.MoveRight) && prevState.IsKeyUp(key.MoveLeft))
    {
        foreach (Object2 o in object2List)
        {
            if (position.Y + playerWidth >= o.position.Y)
            {
                velocity.Y = 0;
            }
            else
            {
                velocity.Y = 3;
            }
        } 
        currentFace = FacePosition.Down;
    }
    else if (Keyboard.GetState().IsKeyDown(key.MoveRight) && prevState.IsKeyUp(key.MoveDown) && prevState.IsKeyUp(key.MoveUp) && prevState.IsKeyUp(key.MoveLeft))
    {
        foreach (Object2 o in object2List)
        {
            if (position.X + playerWidth >= o.position.X)
            {
                velocity.X = 0;
            }
            else
            {
                velocity.X = 3;
            }
        } 
        currentFace = FacePosition.Right;
    }
    else if (Keyboard.GetState().IsKeyDown(key.MoveLeft) && prevState.IsKeyUp(key.MoveDown) && prevState.IsKeyUp(key.MoveRight) && prevState.IsKeyUp(key.MoveUp))
    {
        foreach (Object2 o in object2List)
        {
            if (position.X <= o.position.X + o.width)
            {
                velocity.X = 0;
            }
            else
            {
                velocity.X = -3;
            }
        } 
        currentFace = FacePosition.Left;
    }
    else
    {
        velocity = Vector2.Zero;
    }

    prevState = Keyboard.GetState();
}

很抱歉，如果这没有多大帮助，特别是第一段代码，那就是如何创建多个object2的一个例子。
