私のLoadContent関数が私のスプライトをロードしない（パックマンゲームを構築する）

Question

申し訳ありませんが、XNAを使ってパックマンゲームを作成する方法についてのチュートリアルは、https://www.youtube.com/watch?v=TN3NYT_glmgです。私は最大3つのチュートリアルを見て、問題に遭遇しました。 私はまさに男がしていることに従っていますが、問題はあります。私のスプライトは私の画面に描かれません。私はチュートリアルをトレースして、私が逃したものを見つけようとしました。 あなたの助けに感謝して、私はゲームプログラミングが実際にどのように動作するかを理解するために、このゲームを完了する必要があります。ここ はコード

オブジェクトクラスは

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using Microsoft.Xna.Framework; 
using Microsoft.Xna.Framework.Content; 
using Microsoft.Xna.Framework.Graphics; 

namespace WindowsGame1 
{ 
class Obj 
{ 


    public Texture2D Texture = null; //texture of object; 

    public string TextureName = string.Empty;//name of texture 

    public Vector2 center = Vector2.Zero;//Center of texture 

    public Vector2 position = Vector2.Zero;//Postion of object 

    public float Rotation = 0.0f; //Rotation of Object 

    public float scale = 1.0f; //Scale of the object 

    public float speed = 0.0f; //speed of the object 

    public bool isAlive = true; 

    public Obj(Vector2 pos) 
    { 
     position = pos; 
    } 
    public Obj() 
    { 

    } 


    public virtual void LoadContent(ContentManager Content)//Loads Content 
    { 
     Texture = Content.Load<Texture2D>("Sprites/"+this.TextureName); 
     center = new Vector2(Texture.Width/2, Texture.Height/2); 
    } 

    public virtual void Update(GameTime gameTime)//Updates the gametime 
    { 

    } 

    public virtual void Draw(SpriteBatch spriteBatch)//Draws object/sprites 
    { 
     if (isAlive) 
      return; 


     spriteBatch.Draw(Texture, position, null, Color.White, MathHelper.ToRadians(Rotation), center, scale,SpriteEffects.None, 0); 
    } 

} 
}

Answer 1

あなたのドローコードを見てみましょう。

public virtual void Draw(SpriteBatch spriteBatch)//Draws object/sprites 
{ 
    if (isAlive) 
     return; 


    spriteBatch.Draw(Texture, position, null, Color.White, MathHelper.ToRadians(Rotation), center, scale,SpriteEffects.None, 0); 
} 

オブジェクトは、あなたがそれを描画しない生きているならば....

それはすべきですbe：

public virtual void Draw(SpriteBatch spriteBatch)//Draws object/sprites 
{ 
    if (!isAlive) 
     return; 


    spriteBatch.Draw(Texture, position, null, Color.White, MathHelper.ToRadians(Rotation), center, scale,SpriteEffects.None, 0); 
}
