我最近问了一个问题，他们应该如何与瓷砖地图发生碰撞，并且由于时间的限制，我在游戏中无法做出答案，我即兴创作并让它发挥作用。但现在我正在转向另一个在编码时出现的问题，即我的平台突然停止与玩家发生碰撞。一秒钟他们就可以了，他们没有。
我看了一下，看到平台与玩家互动的方式没有区别，但有些看法不起作用。我不知道他们将如何发生。
Here 是关于他们如何与瓷砖碰撞的最后一篇文章。
Here 是项目的链接，如果您只想查看这堆垃圾代码。
我使用三个类来移动平台，主类Game1，MovingPlatform和Block。 Game1运行所有这些，MovingPlatform帮助列表并使平台打勾，Block帮助与瓷砖碰撞。
问题
我做错了什么让平台不碰撞？
我将从MovingPlatform类开始：
public class MovingPlatform
{
Game1 game1;
public Texture2D Texture;
public Vector2 Velocity;
public Vector2 Position;
public Rectangle Size;
public Rectangle World;
public float Speed;
public bool Up;
public bool Thing;
float Time;
public MovingPlatform(Texture2D Texture, Vector2 Position,float Speed, bool Up)
{
this.Texture = Texture;
this.Position = Position;
this.Speed = Speed;
this.Up = Up;
Thing = true;
Velocity = Vector2.Zero;
Size = new Rectangle((int)Position.X, (int)Position.Y, 50, 25);
}
public void Initialize(Game1 game1)
{
this.game1 = game1;
}
public Player BlockCollision(Player player)
{
Rectangle top = new Rectangle((int)Position.X + 5, (int)Position.Y - 10, Size.Width - 10, 10);
Rectangle bottom = new Rectangle((int)Position.X + 5, (int)Position.Y + Size.Height, Size.Width - 10, 10);
Rectangle left = new Rectangle((int)Position.X - 10, (int)Position.Y + 5, 10, Size.Height - 10);
Rectangle right = new Rectangle((int)Position.X + Size.Width, (int)Position.Y + 5, 10, Size.Height - 10);
if (!player.goingUp)
{
if (top.Intersects(new Rectangle((int)player.Position.X, (int)player.Position.Y, player.Texture.Width, player.Texture.Height)))
{
if (player.Position.Y + player.Texture.Height > Position.Y && player.Position.Y + player.Texture.Height < Position.Y + Texture.Height / 2)
{
player.Position.Y = player.ground = Position.Y - player.Texture.Height;
player.Velocity.Y = 0;
player.isJumping = false;
player.Time = 0;
player.botCollision = true;
}
}
else if (player.isJumping == false && player.ground == Position.Y - player.Texture.Height)
{
player.isJumping = true;
player.initialVelocity = 0;
}
}
return player;
}
public void Update(GameTime gameTime)
{
Time += (float)gameTime.ElapsedGameTime.TotalSeconds;
World = new Rectangle(0, 0, 0, 0);
if (Up == true)
{
if (Thing == true)
{
Position.Y -= 2;
}
else if (Thing == false)
{
Position.Y += 2;
}
}
if (Up == false)
{
if (Thing == true)
{
Position.X -= 2;
}
else if (Thing == false)
{
Position.X += 2;
}
}
}
public void Draw(SpriteBatch spriteBatch)
{
spriteBatch.Draw(Texture, new Rectangle((int)Position.X, (int)Position.Y, Size.Width, Size.Height), Color.White);
}
}
}
块：
public class Block
{
Game1 game1;
public Texture2D Texture;
public Vector2 Position;
public int BlockState;
KeyboardState prevKB;
KeyboardState kbState;
public static bool NextLevel = false;
Rectangle Contain;
public Block(Texture2D Texture, Vector2 Position, int BlockState)
{
this.Texture = Texture;
this.Position = Position;
this.BlockState = BlockState;
Contain = new Rectangle((int)Position.X, (int)Position.Y, 50, 50);
}
public void Initialize(Game1 game1)
{
this.game1 = new Game1();
}
public Player BlockCollision(Player player, GameTime gameTime, Game1 game1)
{
this.game1 = game1;
kbState = Keyboard.GetState();
Rectangle BlockRectangle = new Rectangle((int)Position.X, (int)Position.Y, Texture.Width, Texture.Height);
Rectangle top = new Rectangle((int)Position.X + 5, (int)Position.Y - 10, Texture.Width - 10, 10);
Rectangle bottom = new Rectangle((int)Position.X + 5, (int)Position.Y + Texture.Height, Texture.Width - 10, 10);
Rectangle left = new Rectangle((int)Position.X - 10, (int)Position.Y + 5, 10, Texture.Height - 10);
Rectangle right = new Rectangle((int)Position.X + Texture.Width, (int)Position.Y + 5, 10, Texture.Height - 10);
if (BlockState > 0)
{
for (int i = 0; i < game1.Platforms.Count; i++)
{
if (top.Intersects(new Rectangle((int)game1.Platforms[i].Position.X, (int)game1.Platforms[i].Position.Y, game1.Platforms[i].Texture.Width, game1.Platforms[i].Texture.Height)))
{
game1.Platforms[i].Thing = true;
}
if (bottom.Intersects(new Rectangle((int)game1.Platforms[i].Position.X, (int)game1.Platforms[i].Position.Y, game1.Platforms[i].Texture.Width, game1.Platforms[i].Texture.Height)))
{
game1.Platforms[i].Thing = false;
}
if (left.Intersects(new Rectangle((int)game1.Platforms[i].Position.X, (int)game1.Platforms[i].Position.Y, game1.Platforms[i].Texture.Width, game1.Platforms[i].Texture.Height)))
{
game1.Platforms[i].Thing = false;
}
if (right.Intersects(new Rectangle((int)game1.Platforms[i].Position.X, (int)game1.Platforms[i].Position.Y, game1.Platforms[i].Texture.Width, game1.Platforms[i].Texture.Height)))
{
game1.Platforms[i].Thing = false;
}
}
}
prevKB = Keyboard.GetState();
return player;
}
然后最后是Game1班：
public List<Block> Blocks;
public List<MovingPlatform> Platforms;
protected override void Initialize()
{
Blocks = new List<Block>();
Platforms = new List<MovingPlatform>();
base.Initialize();
}
protected override void LoadContent()
{
movingPlatform = new MovingPlatform(ballSprite, Vector2.Zero, 3.0f, true);
movingPlatform.Initialize(this);
}
void LoadLevel(int level)
{
Blocks.Clear();
Platforms.Clear();
Texture2D platform = Content.Load<Texture2D>("Platform");
for (int x = 0; x < tileWidth; x++)
{
for (int y = 0; y < tileHeight; y++)
{
//Platform Stoper
if (Levels[level][y, x] == '+')
{
Blocks.Add(new Block(movingArea, new Vector2(x * 50, y * 50), 3));
}
//Vertical Moving Platform
if (Levels[level][y, x] == '=')
{
Platforms.Add(new MovingPlatform(platform, new Vector2(x * 50, y * 50), 3.0f, true));
}
}
}
}
protected override void Update(GameTime gameTime)
{
foreach (Block b in Blocks)
{
player = b.BlockCollision(player, gameTime, this);
}
foreach (MovingPlatform m in Platforms)
{
player = m.BlockCollision(player);
m.Update(gameTime);
}
}
protected override void Draw(GameTime gameTime)
{
spriteBatch.Begin(SpriteSortMode.Deferred, BlendState.AlphaBlend, SamplerState.PointClamp, DepthStencilState.Default, RasterizerState.CullCounterClockwise, null, camera.Transform());
foreach (Block b in Blocks)
{
b.Draw(spriteBatch);
}
foreach (MovingPlatform m in Platforms)
{
m.Draw(spriteBatch);
}
spriteBatch.End();
base.Draw(gameTime);
}
}
