首先，我对编程还是比较新的，大约只学习了两个月时间，涉猎了一点控制台应用程序和WinForms，但仍在使用难看的控制台来提高算法水平。但现在，我想开始深入游戏开发，因为这是我学习编程的原因。我偶然发现了MonoGame，虽然比Unity难一些，但是仅凭代码就能创造出一个东西让我感到巨大的成就感。我已经制作了太空侵略者和乒乓球，但是没有涉及精灵动画、使用精灵表和移动角色等内容。所以两天前，我开始制作一个平台游戏，分割了我的精灵表，并创建了一些动画，但现在移动我的角色时完全迷失了。我尝试阅读一些有关向量的教程，但在我的情况下并没有帮助。也许你可以给我提供一些指导。
所以这是我的代码，请帮我找到答案，谢谢您的帮助 :)
那么，不再多说，以下是代码：
Game.cs
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;
namespace MafiaJohnny
{
public class Game1 : Game
{
GraphicsDeviceManager graphics;
SpriteBatch spriteBatch;
private JohnnyPlayer johnnyPlayer;
public Game1()
{
graphics = new GraphicsDeviceManager(this);
Content.RootDirectory = "Content";
}
protected override void Initialize()
{
base.Initialize();
}
protected override void LoadContent()
{
spriteBatch = new SpriteBatch(GraphicsDevice);
Texture2D texture = Content.Load<Texture2D>("JohnnyDone");
johnnyPlayer = new JohnnyPlayer(texture, 2, 4);
}
protected override void UnloadContent()
{
}
protected override void Update(GameTime gameTime)
{
if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed || Keyboard.GetState().IsKeyDown(Keys.Escape))
Exit();
johnnyPlayer.Update(gameTime);
base.Update(gameTime);
}
protected override void Draw(GameTime gameTime)
{
GraphicsDevice.Clear(Color.White);
johnnyPlayer.Draw(spriteBatch, new Vector2(200, 200));
base.Draw(gameTime);
}
}
}
JohnnyPlayer.cs
using System;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.Input;
namespace MafiaJohnny
{
class JohnnyPlayer
{
public Texture2D Texture { get; set; }
public int Rows { get; set; }
public int Columns { get; set; }
private int currentFrame;
private int totalFrames;
//Slow down frame animation
private int timeSinceLastFrame = 0;
private int millisecondsPerFrame = 400;
public JohnnyPlayer(Texture2D texture, int rows, int columns)
{
Texture = texture;
Rows = rows;
Columns = columns;
currentFrame = 0;
totalFrames = Rows * Columns;
}
public void Update (GameTime gameTime)
{
timeSinceLastFrame += gameTime.ElapsedGameTime.Milliseconds;
if (timeSinceLastFrame > millisecondsPerFrame)
{
timeSinceLastFrame -= millisecondsPerFrame;
KeyboardState keystate = Keyboard.GetState();
//Idle animation
if (keystate.GetPressedKeys().Length == 0)
currentFrame++;
timeSinceLastFrame = 0;
if (currentFrame == 2)
currentFrame = 0;
//Walking Animation
if (keystate.IsKeyDown(Keys.Left))
{
}
}
}
public void Draw (SpriteBatch spriteBatch, Vector2 location)
{
int width = Texture.Width/Columns;
int height = Texture.Height / Rows;
int row = (int) ((float) currentFrame/Columns);
int column = currentFrame % Columns;
Rectangle sourceRectangle = new Rectangle(width * column, height * row, width, height);
Rectangle destinationRectangle = new Rectangle((int)location.X, (int)location.Y, width, height);
spriteBatch.Begin();
spriteBatch.Draw(Texture, destinationRectangle, sourceRectangle, Color.White);
spriteBatch.End();
}
}
}
