更高效的制作多个对象的方式 [英] More Efficient Way of making multiple objects

问题描述

我正在尝试用Java进行内存游戏。这个游戏基本上将是一个4x4的网格中的一些正方形，用于测试目的。我创建了我的Square类，并编程了我想要他们在该类中做的事情，然后在另一个类中创建一个方形对象，处理游戏的正常模式。现在，因为我有一个4x4格子的广场，我需要做16个不同的正方形（或至少这就是我现在在想的）。我也需要在相应的地方绘制正方形。

我的问题：创建16个Square对象的最有效的方法是什么，同时还能够单独操作？ （每个都有自己的名字的排序; Square，Square1，Square2等）。

我也使用Slick2D库。

解决方案

如上所述，Square [] [] squareGrid = new Square [4] [4]是一个很好的办法;
然后您可以使用以下方式初始化所有16个：

  for（int i = 0; i< squareGrid。长度; i ++）
 for（int j = 0; j< squareGrid [i] .length; j ++）
 squareGrid [i] [j] = new Square（）; 
  

现在每个Square都有自己的唯一（row，col）id。例如

  squareGrid [1] [2] .callSomeFunctionInSquareClass（）; 
  

可用于操作第二行，第三列的平方。
这样，您将避免扫描所有正方形，以获得网格上特定单元格的方格，从而使其效率更高。

I am trying to make a memory game with Java. The game is basically going to be some squares in a grid that is 4x4 at the moment just for testing purposes. I have created my Square class, and programmed what i want them to do in that class, and then created a square object in another Class that handles the "Normal Mode" of the game. Now since i have a 4x4 grid of squares I need to make 16 different Squares (Or at least that's what i'm thinking at the moment). I also need to draw the Squares in their corresponding place.

My Question: What is the most efficient way of creating 16 of these Square objects while still being able to manipulate them individually? (Sort of like each having their own name; Square, Square1, Square2, etc).

I am also using the Slick2D library.

解决方案

As mentioned above, Square[][] squareGrid = new Square[4][4] is a good way to go about this; then you can initialize all 16 of them using:

 for (int i = 0; i < squareGrid.length; i++)
        for(int j = 0; j < squareGrid[i].length; j++)
            squareGrid[i][j] = new Square();

now each square automatically has its own unique (row, col) id. for example,

squareGrid[1][2].callSomeFunctionInSquareClass();

can be used to manipulate the square at 2nd row, 3rd column. This way you will avoid scanning through all the squares to get the one at a particular cell on the grid, thus making it much more efficient.

happy coding :)
