问题描述
大家好。我们有一个由我们的讲师给出的项目，我们不会继续这个项目。首先是我们的游戏：www.miniclip.com/games/fat-slice/tr/
我们的主要编程语言是C.我们编写了球功能，但存在一些错误。我们没有解决它并实现削减功能的想法。我们使用alleg.lib并在Visual C ++ 2010上工作
Express.We在切割图像后我们对于球的移动并不了解。球移动 - 没有垂直没有水平 - 交叉。他们在不同的地方移动
和不同的方式。他们互相穿过，他们闪烁。双重缓冲不起作用，屏幕上有两个球。你能帮助我们吗？
Hi everyone. We have a project which is given by our lecturer and we don''t move on this project. Firstly our game : www.miniclip.com/games/fat-slice/tr/
Our primary programming language is C. We codified ball function but there is a some mistakes. We don''t fix it and carry out the idea to cutting function. We use alleg.lib and work on Visual C++ 2010
Express.We don''t have an idea about ball''s moving after cutting the image. Balls move as - no vertical no horizontal - cross. They move on different places
and different way. They pass through each other and they are flicker.Double buffering doesn''t work that there is two ball on the screen. Can you help us?
#include <allegro.h>

int main() {
Baslat();
while (!key[KEY_ESC]) {
int width = 220;//width of box
int height = 440;//height of box
int radius = 5;//radius of ball
int x = 110;//initial position of ball
int y = 220;//initial position of ball
int tempX;
int tempY;
//Keep track of direction of motion here.
//0= northwest 1 = southwest, 2 = northeast,
//3 = southeast
int dir;
moveBall();
}
Bitir();
return 0;

void moveBall(){

switch(dir){
case 0:
//Direction is northwest.
if((x <= radius) || (y <= radius)){
//Ball has collided with either the left wall or
// the top wall.
//Get a new direction. Note that if the new
// direction is the same as the old one, control
// will come back to here to get still another
// direction the next time the functionis called.
dir = rand() % 4;
}else{
//No collision, set new location for the ball
--x;
--y;
}//end else
break;
case 1:
//Direction is southwest.
if(((x <= radius) || (y >= (height - radius)))){
//get a new direction
dir = rand() % 4;
}else{
//set new location for the ball
--x;
++y;
}//end else
break;
case 2:
//Direction is northeast.
if(((x >= (width - radius)) || (y <= radius))){
//get a new direction
dir = rand() % 4;
}else{
//set new location for the ball
++x;
--y;
}//end else

case 3:
//Direction is southeast
if((((x >= (width - radius)) ||
(y >= (height - radius))))){
//get a new direction
dir = rand() % 4;
}else{
//set new location for the ball
++x;
++y;
}//end else
}//end switch
这不完全正常。我们有一些切割形状和弹跳球的问题。我们制作弹跳球，但球是闪烁的。双缓冲不起作用。我们的另一个问题是两个形状相同的球通过彼此。我们怎么能解决这个问题？
所以我们的另一个问题 - 我认为这是一个大问题 - 我们不会削减形状。我们能做些什么呢？
我们对切片的形状一无所知。你能帮助我们吗？并且你发送的功能比那更好
我们快点因为我们应该在6天内完成这个项目。
注意：我们正在使用Allegro v4.2.3。
是否有人用简单的代码帮助我们？

This is not working exactly. We have some problems that cutting shape and bouncing ball. We make bouncing ball but the ball is flicker. Double buffering is not work on it. Our another problem is that two balls ,which are in the shape, through pass each other. How can we fix that?
So our another problem - i think it is a big problem - that we don''t cut the shape. What can we do to make it?
We don''t have an idea about slicing the shape. Can you help us? And you send the function better than that
We hurry up because we should finish this project in 6 days.
Note : We are using Allegro v4.2.3.
Is there someone who help us with a simple codes?
