我看到了多个使用矩形作为数组的教程。但他们的入侵者却没有生气。我正在为我的入侵者使用精灵表,并且我需要将它们全部动画化...如何做到这一点?
这是我的入侵者类别:
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);
}
}
}
这展示了我如何为入侵者制作动画。我可以修改部分代码,以便有 5 行入侵者和 10 列吗?我自己可以做动作,只需要阵法。预先感谢!
实现你想要的最好方法是将所有入侵者的东西封装在它自己的类中。假设你称之为入侵者。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,你就会:
Invader[,] array = new Invader[columns,rows];
您将在游戏开始时初始化。在
Update()
方法中,您将循环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);
}
}
同样,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制作一系列太空入侵者。
Invader[] InvaderArray = new Invader[x,y];
然后您必须致电:
InvaderArray[x,y].Update(gameTime);
然后在draw方法中你需要绘制它。
InvaderArray[x,y].Draw(spriteBatch)
