如何随机生成关卡？

Question

我目前正在硬编码 10 个不同的实例，如下面的代码，但我想创建更多。我想知道是否可以为每个块生成一个随机 X 值，而不是为新关卡设置相同的布局（这将是它进入关卡的距离）。一个 100,000 像素宽的关卡就足够了，但如果有人知道一个系统可以让关卡继续下去，我也想知道。这基本上就是我现在定义块的方式（删除了不相关的代码）：

block = new Block(R.drawable.block, 400, platformheight);
block2 = new Block(R.drawable.block, 600, platformheight);
block3 = new Block(R.drawable.block, 750, platformheight);

400 是 X 位置，我想在关卡中随机放置，platformheight 变量定义了我不想更改的 Y 位置。

Answer 1

考虑到每个块都需要比前一个块更远，

List<Block> blocks = new LinkedList<Block>();
Random rnd = new Random(System.currentTimeMillis());

int x = 400;

while (youNeedMoreBlocks)
{
    int offset = rnd.nextInt(400) + 100; //500 is the maximum offset, this is a constant
    x += offset;                         //ofset will be between 100 and 400

    blocks.add(new Block(R.drawable.block, x, platformheight));

    //if you have enough blocks, set youNeedMoreBlocks to false
}

但这在我看来过于简单化了。要么我不明白你的问题，要么就是这么简单。

编辑：

对于这样的作业：

block.setY(three_quarters - 10); 
block2.setY(three_quarters - 10); 
block3.setY(three_quarters - 10);

你需要修改循环：

List<Block> blocks = new LinkedList<Block>();
Random rnd = new Random(System.currentTimeMillis());

int x = 400;

while (youNeedMoreBlocks)
{
    int offset = rnd.nextInt(400) + 100; //500 is the maximum offset, this is a constant
    x += offset;                         //ofset will be between 100 and 400

    Block tmp = new Block(R.drawable.block, x, platformheight);
    tmp.setY(three_quarters - 10);                 
            //do with tmp everything you need to apply to each block

    blocks.add(tmp);

    //if you have enough blocks, set youNeedMoreBlocks to false
}

另一个明智的想法是在玩家靠近地图边缘时按需生成块，这样您的加载时间就会更快。
