c语言写双人贪吃蛇，双人模式下食物生成出现bug
我将贪吃蛇分为两个模式，用reStart控制选择进入单人模式（reStart1）还是双人模式（reStart2），进入单人模式能完美运行，但是进入双人模式时，画面卡着不动，去掉食物生成又可以运行。
我用的Vusial C++ 6.0，使用了Easy X插件来绘制游戏界面
源代码是
//头文件
#include<graphics.h>
#include<conio.h>
#include<ctime>
//窗口大小
int WindowX=640,WindowY=480;
//食物生成位置在框内

foodPositionX=(rand()%(WindowX/20-2)+1)*20+10;

我对于双人模式，是想让两条蛇同时争夺三个食物，只需要判定食物生成和蛇头以及其他食物不重合就行了。双人模式蛇可以过自己的身子，但是不能碰到另一条蛇的身子，如果是头对头相撞，则比较长度来判断胜负（个人觉得如果要使用for循环来判定食物不在两条蛇身子上，运算次数几何倍增，电脑算不过来。）。我检擦了很久都没找不问题，请帮帮我。
第一个问题：
加载食物会卡住，是因为你那里生成食物条件没有绝对出口，if ... else if ，经过我调试，会有某个食物坐标生成是没法满足if ...else if 这两个条件，导致一直在死循环中，所以就卡在了，你要改成这样就好了！
//设置三个食物的坐标
FoodX = FoodPositionX();
FoodY = FoodPositionY();
while (FoodCanPut == false) {
if (FoodX != Snake2X[0] && FoodY != Snake2Y[0] && FoodX != Snake3X[0] && FoodY != Snake3Y[0]) {
FoodCanPut = true;
} else /*if (FoodX == Snake2X[0] && FoodY == Snake2Y[0] || FoodX == Snake3X[0] && FoodY == Snake3Y[0])*/ {
FoodX = FoodPositionX();
FoodY = FoodPositionY();
FoodCanPut = false;
}
}
Food2X = Food2PositionX();
Food2Y = Food2PositionY();
while (Food2CanPut == false) {
if (Food2X != Snake2X[0] && Food2Y != Snake2Y[0] && Food2X != Snake3X[0] && Food2Y != Snake3Y[0] && Food2X != FoodX && Food2Y != FoodY) {
Food2CanPut = true;
} else /*if (FoodX == Snake2X[0] && Food2Y == Snake2Y[0] || Food2X == Snake3X[0] && Food2Y == Snake3Y[0] || Food2X == FoodX && Food2Y == FoodY)*/ {
Food2X = Food2PositionX();
Food2Y = Food2PositionY();
Food2CanPut = false;
}
}
Food3X = Food3PositionX();
Food3Y = Food3PositionY();
while (Food3CanPut == false) {
if (Food3X != Snake2X[0] && Food3Y != Snake2Y[0] && Food3X != Snake3X[0] && Food3Y != Snake3Y[0] && Food3X != FoodX && Food3Y != FoodY && Food3X != Food2X && Food3Y != Food2Y) {
Food3CanPut = true;
} else /*if (Food3X == Snake2X[0] && Food3Y == Snake2Y[0] || Food3X == Snake3X[0] && Food3Y == Snake3Y[0] || Food3X == FoodX && Food3Y == FoodY || Food3X == Food2X && Food3Y == Food2Y)*/ {
Food3X = Food3PositionX();
Food3Y = Food3PositionY();
Food3CanPut = false;
}
}
第二个问题，当蛇吃到食物后，重写加载另一个食物也会卡住，问题和上面是一样的。改一下就好了！

} else /*if (FoodX == Snake2X[0] && FoodY == Snake2Y[0] || FoodX == Snake3X[0] && FoodY == Snake3Y[0] || FoodX == Food2X && FoodY == Food2Y || FoodX == Food3X && FoodY == Food3Y)*/ {

至此，你所遇到的卡住问题应该得到了解决！
花了好多时间看你的代码和调试，点个采纳吧！
Easy X，
以前也捯饬过一阵, 官方群氛围还是挺好的，其实可以直接在里面提问的。
稍等，我看下代码能不能里出来代码逻辑。
生成食物的话，可以用一个坐标数组保存非蛇体坐标，并计数为count，然后rand一个数[0,count)就行，这个数就是数组中非蛇身的坐标
生成实物那里和蛇的坐标冲突了
生成食物前，先判断两条蛇的坐标，然后用随机数获取食物坐标，生成坐标
