循環通過瓷磚，只能得到可以得到第一個瓷磚的索引

Question

我已經創建了一個非常基本的瓷磚系統，我希望能夠獲得鼠標懸停在當前的瓷磚，這對於第一個瓷磚創建，但除此之外，我什麼也沒有看。

下面是設置和繪製圖塊的代碼以及「Currently hovering」文本。

private static final int TILE_WIDTH = 64; 
private static final int TILE_HEIGHT = 64; 

private static Tile[][] gridTiles = new Tile[(int)Math.ceil(Gdx.graphics.getHeight()/TILE_HEIGHT)][(int)Math.ceil(Gdx.graphics.getWidth()/TILE_WIDTH)]; 

public CombatGrid() {} // Cannot instantiate this class 

static {   
    // Rows 
    for(int r = 0; r < gridTiles.length; r++) { 
     // Columns 
     for(int c = 0; c < gridTiles[0].length; c++) { 
      gridTiles[r][c] = new Tile((c * TILE_WIDTH), (r * TILE_HEIGHT), TILE_WIDTH, TILE_HEIGHT); 
      System.out.println("New tile("+r+","+c+") was created at: x: " + (c * TILE_WIDTH) + " y: " + (r * TILE_HEIGHT)); 
     } 
    } 
} 

public static void draw(Batch batch) { 
    for(int r = 0; r < gridTiles.length; r++) { 
     for(int c = 0; c < gridTiles[0].length; c++) { 
      gridTiles[r][c].draw(batch); 
      if(gridTiles[r][c].hovering(Gdx.input.getX(), Gdx.input.getY())) { 
       Assets.defaultFont.draw(batch, "Current hover index("+r+","+c+")", Client.TOP_LEFT_X + 10, Client.TOP_LEFT_Y - 30); 
      } 
     } 
    } 
} 

文本僅當我do sth對瓷磚上顯示[0] [0]

下面是來自瓷磚類

public boolean hovering(float x, float y) { 
    if((x > this.x) && (x < this.width)) { 
     if((y > this.y) && (y < this.height)) { 
      return true; 
     } 
    } 
    return false; 
} 

鼠標輸入我是懸停方法傳遞到盤旋是正確的，當我移出0,0瓦時，它不再被繪製。

而且，我調試我的鼠標位置

Assets.defaultFont.draw(batch, "Curret mouse X: " + Gdx.input.getX() + " Y: " + Gdx.input.getY(), Client.TOP_LEFT_X + 10, Client.TOP_LEFT_Y - 10); 

它表明，我已經設置了數學是正確的，或者至少應該是，除非我錯過了什麼

現在，我知道所有的瓷磚被greated和靜態初始化這說明正確放置因爲Debugging Statement的，：

Answer 1

試試這個;

public boolean hovering(float x, float y) { 
    if((x > this.x) && (x < this.x + this.width)) { 
     if((y > this.y) && (y < this.y + this.height)) { 
      return true; 
     } 
    } 
    return false; 
}
