C#XNA - 创建一个Space Invaders数组

所以我看到多个教程使用矩形作为数组。但他们的入侵者并没有动画。我正在为我的入侵者使用spritesheet,我需要让它们全部动画......怎么做?

这是我的入侵者类:

using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Storage;
using Microsoft.Xna.Framework.Audio;
using Microsoft.Xna.Framework.Content;
using Microsoft.Xna.Framework.GamerServices;
using Microsoft.Xna.Framework.Graphics;
using Microsoft.Xna.Framework.Input;
using Microsoft.Xna.Framework.Media;
using Microsoft.Xna.Framework.Net;

namespace SpaceInvaders
{
    class botInvaders
    {

        public botInvaders()
        {

        }

        public static Texture2D BotInvaderTex;
        Rectangle BotInvaderHitBox;
        public static Vector2 BotInvaderPos = new Vector2(0, 28), BotInvaderOrigin;

        int BotInvaderCurrentFrame = 1, BotInvaderFrameWidth = 52, BotInvaderFrameHeight = 88;

        float Timer = 0f, Interval = 100f;

        public void Initialize()
        {

        }

        public void LoadContent(ContentManager Content)
        {
            BotInvaderTex = Content.Load<Texture2D>(".\\gameGraphics\\gameSprites\\botInvaders\\normalInvaders\\invaderShip1");
        }

        public void Update(GameTime gameTime)
        {
            BotInvaderHitBox = new Rectangle(BotInvaderCurrentFrame * BotInvaderFrameWidth, 0, BotInvaderFrameWidth, BotInvaderFrameHeight);
            BotInvaderOrigin = new Vector2(BotInvaderHitBox.X / 2, BotInvaderHitBox.Y / 2);

            Timer += (float)gameTime.ElapsedGameTime.Milliseconds;

            if (Timer > Interval)
            {
                BotInvaderCurrentFrame++;
                Timer = 0f;
            }

            if (BotInvaderCurrentFrame == 2)
            {
                BotInvaderCurrentFrame = 0;
            }

            BotInvaderHitBox = new Rectangle(BotInvaderCurrentFrame * BotInvaderFrameWidth, 0, BotInvaderFrameWidth, BotInvaderFrameHeight);
            BotInvaderOrigin = new Vector2(BotInvaderHitBox.Width / 2, BotInvaderHitBox.Height / 2);
        }

        public void Draw(SpriteBatch spriteBatch)
        {
            spriteBatch.Draw(BotInvaderTex, BotInvaderPos, BotInvaderHitBox, Color.White, 0f, Vector2.Zero, 1.0f, SpriteEffects.None, 0);      
        }
    }
}

这显示了我如何为入侵者设置动画。我可以使用修改后的代码部分,以便有5行入侵者和10行吗?我自己可以做动作,我只需要阵列。提前谢谢!

实现所需内容的最佳方法是将所有入侵者的东西封装在自己的类中。假设你称之为Invader。它可能看起来像这样:

public class Invader
{
    private Texture2D _texture;

    public Invader(Texture2D texture)
    {
        _texture = texture;
    }

    public void Update(GameTime gameTime)
    {
        // Update logic for this individual invader goes here
    }

    public void Draw(SpriteBatch spriteBatch)
    {
        // Draw routine for this invidual invader goes here
    }
}

然后,你有:

Invader[,] array = new Invader[columns,rows];

你在游戏开始时初始化。在Update()方法中,您将遍历数组并调用入侵者的Update()方法:

for (int y = 0;y < rows;++y)
{
    for (int x = 0;x < columns;++x)
    {
        array[x,y].Update(gameTime);
    }
}

,类似地,在Draw()方法中,您将执行相同的循环并调用:

array[x,y].Draw(spriteBatch);

封装它!您可以使用入侵者类来创建一个空间入侵者数组。

Invader[] InvaderArray = new Invader[x,y];

然后你必须打电话:

InvaderArray[x,y].Update(gameTime);

然后在draw方法中你需要绘制它。

InvaderArray[x,y].Draw(spriteBatch)
