弹跳球的基础程序

弹跳球的基础程序

根据童老师的课程写的，做一下记录
实现功能：1 左右弹跳 2 速度延迟

//弹跳小球的相关小程序

/*
//分步实现，首先打印小球的起始位置

#include<stdio.h>
int main()
{

	int i, j;
	int x=10, y=10;
	int velocity = 1;

	for(i = 0; i <=y; i++)
		printf("\n");                   
	for (j = 0; j <= x; j++)                //确立了X与Y轴
		printf(" ");
	printf("0\n");

	system("pause");
	return 0;
}

/*
/第一步完成，其次完成小球竖直下降的部分

#include<stdio.h>
#include<stdlib.h>

int main()
{

	int i, j;
	int x = 10, y = 1;
	int velocity = 1;

	while (1)
	{
		y += velocity;
		system("CLS");

		for (i = 0; i <= y ; i++)
            printf("\n");
		for (j = 0; j <= x; j++)   //确立了X与Y轴
		    printf(" ");
        printf("0\n");

    }

	system("pause");
	return 0;
}
*/

/*
//第二步完成，进行第三步：限制下降的上下限以及下降速度

#include<stdio.h>
#include<stdlib.h>
#include<Windows.h>

int main()
{

	int i, j;
	int x = 10, y = 1;
	int velocity = 1;

	while (1)
	{
		Sleep(40);

		y += velocity;
		system("CLS");

		if (y > 10 || y < 1)
			velocity = -1 * velocity;

		for (i = 0; i <= y; i++)
			printf("\n");
		for (j = 0; j <= x; j++)   //确立了X与Y轴
			printf(" ");
		printf("0\n");

	}

	system("pause");
	return 0;
}
