瓷砖尺寸算法

本文介绍了瓷砖尺寸算法的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我在做瓷砖的游戏在C + +。现在，当游戏加载所有的瓷砖基础上把自己：

I'm making a tile game in c++. Right now when the game loads all the tiles place themselves based on:

tilesize - >它们是正方形所以这是宽度和高度

tilesize -> they are squares so this is width and height

tile_count_x

tile_count_y

我有以下变量：

desktop_width

desktop_height

game_window_width

game_window_height

tile_count_x

tile_count_y

，我在寻找一种算法，将设置特定的桌面和tile_count限制一个适当的窗口大小。然后在此，我希望我的瓷砖具有偏移，将边界X％左右，这将根本决定tilesize太窗口：

Based on these values, I'm looking for an algorithm that will set an appropriate window size given the desktop and tile_count constraints. Then within this, I want my tiles to have an offset that will border x% around the window which will basically decide the tilesize too:

例：如果我有10 * 3瓦的话：

Example:If I have 10 * 3 of tiles then:

______________________________
Window Title              _[]X
------------------------------
|                            |
|    [][][][][][][][][][]    | 
|    [][][][][][][][][][]    |
|    [][][][][][][][][][]    |
|                            |
------------------------------

我只是不知道所需要的公式来做到这一点。

I'm just not sure the formula required to do this.

编辑（从评论）：

Tilesize变化，tilecountx和y是静态
我想，因为它可以给桌面分辨率的gamewindow是一样大，但我也希望它的长宽比尊重tilecoutx和tilecounty

我发现我的意思的例子，在Windows中打开扫雷

I found an example of what I mean, open up Minesweeper in Windows

推荐答案

下面是我如何解决它？

    	//WINDOW SIZE SETUP

    	//choose the smaller TILE_SIZE
    	if (DESKTOP_WIDTH / TILE_COUNT_X > DESKTOP_HEIGHT / TILE_COUNT_Y)
    	{
    		TILE_SIZE = DESKTOP_HEIGHT / TILE_COUNT_Y;
    	}
    	else
    	{	
    		TILE_SIZE = DESKTOP_WIDTH / TILE_COUNT_X;
    	}
    	//Set screen size and consider a 5 tile border
    	SCREEN_WIDTH = TILE_SIZE * (TILE_COUNT_X + 5);
    	SCREEN_HEIGHT = TILE_SIZE * (TILE_COUNT_Y + 5);

    	//resize window until it satisfies resolution constraints
    	while( SCREEN_WIDTH > (DESKTOP_WIDTH - (DESKTOP_WIDTH * 0.07)))
    	{
    		TILE_SIZE --;
    	SCREEN_WIDTH = TILE_SIZE * (TILE_COUNT_X + 5);
    	SCREEN_HEIGHT = TILE_SIZE * (TILE_COUNT_Y + 5);
    	}

    	while( SCREEN_HEIGHT > (DESKTOP_HEIGHT - (DESKTOP_HEIGHT * 0.15)))
    	{
    		TILE_SIZE -- ;
    	SCREEN_WIDTH = TILE_SIZE * (TILE_COUNT_X + 5);
    	SCREEN_HEIGHT = TILE_SIZE * (TILE_COUNT_Y + 5);
    	}
for(int i = 0; i < 8; ++i)     //Ensure resolution is multiple of 8
{
    if (SCREEN_WIDTH % 8 != 0) //remainder means not multiple of 8
    {
    	SCREEN_WIDTH += 1;
    }

    if (SCREEN_HEIGHT % 8 != 0)
    {
    	SCREEN_HEIGHT += 1;
    }
}
    	X_OFFSET = (SCREEN_WIDTH - (TILE_SIZE * TILE_COUNT_X)) / 2;
    	Y_OFFSET = (SCREEN_HEIGHT - (TILE_SIZE * TILE_COUNT_Y)) / 2;
