碰撞块运动

Question

我在阻止运动方面有问题，我已经阅读了关于在碰撞中阻止运动的问题，但是我对自己的问题一无所知。 如果您能给我逻辑，我将尝试解决自己的问题。 我希望你能帮我这个我的球员更新

：EDIT：感谢Kai Hartmann的回复我的问题是2D图形，我想知道当object1与object2碰撞时如何停止运动

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 < vector2.X || vector1.X > vector2.X + object2.Width ||
    vector1.Y + object1.Height < vector2.Y || vector1.Y > vector2.Y + object2.Height)
    {

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

就我而言，不需要冲突检查方法:)我已经非常快地编写了这段代码，但是应该可以吗？ 我假设您要检查玩家的方式是否有问题，并且还假设您的玩家方式中可能有多个物体，所以为此，我建议为“ Solid”物体制作一个类并给它位置，宽度和高度。 然后列出此类以包含多个“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，在播放器更新功能中，您将引用此对象列表。

// 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();
}

抱歉，如果没有太大帮助，尤其是第一段代码，那非常说明如何创建多个object2。
