java控制台字符动画 java小程序之控制台字符动画的实现
Tom带师 人气:0想了解java小程序之控制台字符动画的实现的相关内容吗，Tom带师在本文为您仔细讲解java控制台字符动画的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：java控制台程序,java从控制台输入字符串,java从控制台输入，下面大家一起来学习吧。
说在前面
大一软件工程在读，java萌新一只，第一次写博客，技术很菜勿喷。如有错误欢迎指出！
这个小程序是给朋友的生日礼物，耗时半天，实际写起来碰到的知识点和困难还挺多，故发出来分享一下。
程序效果
可设置画布尺寸，添加图形元件，设置元件坐标和效果。元件闪烁效果，横向滚动效果。
代码呈现
图形元件父类
public class Shape implements IShape{
String shape[];//图形形状字符串
String shape_flicker[];//闪烁形状字符串
int height,width;//高、宽
int x,y;//位置坐标
String id;//元件id，用于制作动画效果时获取元件
public Shape(int x,int y,String id) {//构造方法初始化
this.x=x;this.y=y;this.id=id;
}
public Shape(String id) {
this(0,0,id);
}
}
图形绘画工具类
import java.util.HashMap;
public class Shapes {//存放图形元件
int width,height;//画布大小
public static String canvas[];//画布图像字符串
HashMap<String, Shape> ShapeMap=new HashMap<String,Shape>();//图形元件容器，添加到画布的图形都会存放在这
public Shapes(int width ,int height) {//初始化空白画布
this.width=width;
this.height=height;
canvas=new String[height];
for(int h=0;h<height;h++) {
String line="";
for(int w=0;w<width;w++){
line+=" ";
}
canvas[h]=line;
}
}
public void draw(Shape myShape) {//将元件添加到画布中
int px,py;
px=myShape.x;
py=myShape.y;
int count=0;
if(myShape.height+py>height-1) {
System.out.println("超出画布边界!!");
return;
}
if(myShape.width+px>width-1) {
System.out.println("超出画布边界!!");
return;
}
ShapeMap.put(myShape.id,myShape);//将元件添加到容器中
for(String line :myShape.shape) {
char Line[]=canvas[py+count].toCharArray();
for(int i=px;i<myShape.width+px;i++) {
Line[i]=line.charAt(i-px);
}
canvas[py+count]=String.valueOf(Line);
count++;
}
}
public void drawCanvas() {//绘制画布
System.out.print(" ");
for(int i=0;i<width;i++) {
System.out.print(i%10);
}
System.out.println();
int count=0;
for(String line: canvas) {
System.out.println(count+line);
count++;
}
}
}
动画类
import java.io.IOException;
public class Animation {//用于动画效果
long timer;//计时器
int rolled;//滚动计数器
private Shapes shapes;//图形工具
public Animation() {
timer=0;
rolled=0;
init();
}
public void flicker(String id,int interval) {//闪烁效果,id为元件的id，interval是闪烁间隔
Shape myShape=shapes.ShapeMap.get(id);
String shape_flicker[]=myShape.shape.clone(); //闪烁图像
for(int i=0;i<shape_flicker.length;i++) {
shape_flicker[i]=shape_flicker[i].replaceAll("O","-");//将O替换为-实现闪烁效果
}
myShape.shape_flicker=shape_flicker;
//绘制图像
if(timer%interval==0) {
int px,py;
px=myShape.x;
py=myShape.y;
int count=0;
if((timer/interval)%2==0) {
for(String line :myShape.shape_flicker) {
char Line[]=Shapes.canvas[py+count].toCharArray();
for(int i=px;i<myShape.width+px;i++) {
Line[i]=line.charAt(i-px);
}
Shapes.canvas[py+count]=String.valueOf(Line);
count++;
}
}else {

for(int i=px;i<myShape.width+px;i++) {
Line[i]=line.charAt(i-px);
}
Shapes.canvas[py+count]=String.valueOf(Line);
count++;
}
}
}
}
public void roll(String id,int from ,int to,int speed) {//滚动效果,id为元件id，from，to为起始和终止点，speed为滚动速度
rolled+=speed;
Shape myShape=shapes.ShapeMap.get(id);
String shape_roll[]=myShape.shape.clone();
myShape.x=from+rolled%(to-from);
int px,py;
px=myShape.x;
py=myShape.y;
int count=0;
System.out.println("rolled:"+rolled+"px:"+px);
for(String line :shape_roll) {
char Line[]=Shapes.canvas[py+count].toCharArray();
for(int i=from;i<to;i++) {
if(i>=px&&i<=to&&i<px+line.length()) {
Line[i]=line.charAt(i-px);
}else {
Line[i]=' ';
}
}
Shapes.canvas[py+count]=String.valueOf(Line);
count++;
}
}
private void init() {//初始化画布，添加元件
shapes=new Shapes(120,50);
shapes.draw(new Shape_Text(5,10,"HB1"));
shapes.draw(new Shape_Nineteen(52,21,"Nt1"));
shapes.draw(new Shape_Cake(45,30,"Cake1"));
shapes.draw(new Shape_Bubble(10,25,"BB1"));
shapes.draw(new Shape_Bubble(90,25,"BB2"));
}
public void play(int sleep) throws IOException, InterruptedException {//播放动画,sleep设置刷新间隔
while(true) {
if(timer>300) {
timer=0;
}
cls();
if(timer<100) {
flicker("HB1",5);
}else {
roll("HB1",0,110,1);
}
flicker("Nt1",10);
shapes.drawCanvas();
timer++;
Thread.sleep(sleep);
System.out.println(timer);
}
}
public static void cls() throws IOException, InterruptedException//清屏方法(ide中无效)
{
new ProcessBuilder("cmd", "/c", "cls").inheritIO().start().waitFor(); // 清屏命令
}
}
主类
import java.io.IOException;
public class Main {//启动动画
public static void main(String args[]) throws InterruptedException, IOException {
Animation animator=new Animation();
animator.play(30);
}
}
具体图形子类（Happy Birthday文字）
public class Shape_Text extends Shape{//继承图形父类
String s[]= {//字符图像
"==================================================================================================",
"= O O OO OOOO OOOO O O OOOOO OOOOO OOOOOO OOOOOO O O OOOOO OO O O =",
"= O O O O O O O O O O O O O O O OO O O O O O O O O =",

"=================================================================================================="
};
public Shape_Text(int i, int j,String id) {

this.shape=s;

this.width=shape[0].length();
