问题描述
帮助：C ++ 2D阵列迷宫游戏，移动物体。
我有这个迷宫游戏，我想制作，
在这个迷宫中'@'符号应该能够在网格中移动一个角色
，所以这基本上就像移动巨石游戏一样你可以使用@来移动对象
迷宫中的人物。
但现在的问题是，代码中写了如何在整个迷宫中移动@
符号，但是你如何实际放置另一个角色
在迷宫中用@符号推动它移动。
有人可以帮帮我吗？

Help : C++ 2D array maze game , moving objects .
Hi , I have got this maze game that I want to make ,
in this maze the '@' symbol should be able to move a character
in the grid , so this is basically like moving boulders game where you can
move object by using @ and pushing some characters in the maze .
But the problem now is that there is the code written how to move the @
symbol throughout the maze , however how do you actually put another character
in the maze and make it move by pushing it with @ symbol .
Can anybody help me out ?

}推荐答案
It looks like you have a CASE statement looking at the square your mouse is moving into.
in that case statement, if the character is the boulder, then you want to move the boulder in the same direction the mouse is about to move.
Adding the boulder character is as simple as defining which character you want to use (let’s say ’O’) then putting it in your maze somewhere there isn’t already another item.
Quick and Dirty way to do this:
Choose a random X & Y
While (maze(X,Y) is not empty
{
Add 1 to X
If X > width, X=0; Y+=1;
If Y > height, Y = 0
}
Put your boulder at (X,Y)
