C# 向量列表需要一些基础知识
嗨,我有这些向量:C# 向量列表需要一些基础知识,c#,xna-4.0,C#,Xna 4.0,嗨,我有这些向量: Vector2 ground1p1 = new Vector2(0,430); Vector2 ground1p2 = new Vector2(200,430); Vector2 ground1p3 = new Vector2(0, 290); Vector2 ground1p4 = new Vector2(280, 340); if (DetectPlayerAndGround1Collision2(playerPosition,groun
Vector2 ground1p1 = new Vector2(0,430);
Vector2 ground1p2 = new Vector2(200,430);
Vector2 ground1p3 = new Vector2(0, 290);
Vector2 ground1p4 = new Vector2(280, 340);
if (DetectPlayerAndGround1Collision2(playerPosition,ground1p1,player,ground1) == true)
{
hasJumped = false;
velocity.Y = 0f;
}
if (DetectPlayerAndGround1Collision2(playerPosition, ground1p2, player, ground1) == true)
{
hasJumped = false;
velocity.Y = 0f;
}
public class Game1 : Microsoft.Xna.Framework.Game
{
GraphicsDeviceManager graphics;
SpriteBatch spriteBatch;
public Game1()
{
graphics = new GraphicsDeviceManager(this);
Content.RootDirectory = "Content";
}
protected override void Initialize()
{
base.Initialize();
}
bool hasJumped = true;
Vector2 velocity;
Texture2D player;
Texture2D ground1;
List<Vector2> vectors = new List<Vector2>();
Vector2 playerPosition = new Vector2(30, 300);
Vector2 ground1p1 = new Vector2(0,430);
Vector2 ground1p2 = new Vector2(200,430);
Vector2 ground1p3 = new Vector2(0, 290);
Vector2 ground1p4 = new Vector2(280, 340);
我想把它们放在一个列表中,所以不要这样做:
Vector2 ground1p1 = new Vector2(0,430);
Vector2 ground1p2 = new Vector2(200,430);
Vector2 ground1p3 = new Vector2(0, 290);
Vector2 ground1p4 = new Vector2(280, 340);
if (DetectPlayerAndGround1Collision2(playerPosition,ground1p1,player,ground1) == true)
{
hasJumped = false;
velocity.Y = 0f;
}
if (DetectPlayerAndGround1Collision2(playerPosition, ground1p2, player, ground1) == true)
{
hasJumped = false;
velocity.Y = 0f;
}
public class Game1 : Microsoft.Xna.Framework.Game
{
GraphicsDeviceManager graphics;
SpriteBatch spriteBatch;
public Game1()
{
graphics = new GraphicsDeviceManager(this);
Content.RootDirectory = "Content";
}
protected override void Initialize()
{
base.Initialize();
}
bool hasJumped = true;
Vector2 velocity;
Texture2D player;
Texture2D ground1;
List<Vector2> vectors = new List<Vector2>();
Vector2 playerPosition = new Vector2(30, 300);
Vector2 ground1p1 = new Vector2(0,430);
Vector2 ground1p2 = new Vector2(200,430);
Vector2 ground1p3 = new Vector2(0, 290);
Vector2 ground1p4 = new Vector2(280, 340);
当我在写的末尾写“vectors”时,问题就出在这里,没有什么事情会像我没有声明的那样被列为一个列表:
Vector2 ground1p1 = new Vector2(0,430);
Vector2 ground1p2 = new Vector2(200,430);
Vector2 ground1p3 = new Vector2(0, 290);
Vector2 ground1p4 = new Vector2(280, 340);
if (DetectPlayerAndGround1Collision2(playerPosition,ground1p1,player,ground1) == true)
{
hasJumped = false;
velocity.Y = 0f;
}
if (DetectPlayerAndGround1Collision2(playerPosition, ground1p2, player, ground1) == true)
{
hasJumped = false;
velocity.Y = 0f;
}
public class Game1 : Microsoft.Xna.Framework.Game
{
GraphicsDeviceManager graphics;
SpriteBatch spriteBatch;
public Game1()
{
graphics = new GraphicsDeviceManager(this);
Content.RootDirectory = "Content";
}
protected override void Initialize()
{
base.Initialize();
}
bool hasJumped = true;
Vector2 velocity;
Texture2D player;
Texture2D ground1;
List<Vector2> vectors = new List<Vector2>();
Vector2 playerPosition = new Vector2(30, 300);
Vector2 ground1p1 = new Vector2(0,430);
Vector2 ground1p2 = new Vector2(200,430);
Vector2 ground1p3 = new Vector2(0, 290);
Vector2 ground1p4 = new Vector2(280, 340);

我不认为添加另一个循环会有助于提高XNA的性能。诚实地说,适当的数据结构可以更好地处理这个问题。我知道这不会有什么帮助。lol:D我希望以后的写作对我来说很容易,我不想复制粘贴100次。不知何故,列表向量=新列表();在我向列表中添加向量时不起作用错误出现您可能需要使用文件顶部的System.Collections.Generic。另请参见列表向量=新列表();在我编写向量时。添加“向量”是一个字段,它的用法与公共类Game1:Microsoft.Xna.Framework.Game之后的类型类似{
