【问题描述】:
首先,我对编程相当陌生,大约 2 个月后,我涉足了控制台应用程序、WinForms,并且仍然使用丑陋的控制台来更好地处理算法。但现在,我想开始深入研究游戏编程,因为这就是我想学习编程的原因。我偶然发现了 MonoGame,虽然它比 Unity 更难,但在仅使用代码创建某些东西后,我获得了巨大的成就感。我已经制作了 Space Invaders 和 Pong 但与精灵动画、使用精灵表和移动玩家无关。所以 2 天前,我开始了一个平台游戏,分割了我的精灵表,做了一些动画,现在是时候移动我的播放器了,我完全迷失了。我尝试阅读一些关于向量的教程,但对我来说没有帮助。也许你可以对这件事有所了解。
那么,废话不多说,代码如下:
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();
}
}
}
这是我的代码,帮我找个答案!谢谢你是我的意思:)
