下面我將和大家分享一個用Java做的簡單小程序，用來實(shí)現(xiàn)控制臺字符動畫的效果。本文供大家參考，如有錯誤或是考慮不周的地方，還望大家不吝指出。
程序效果
可設(shè)置畫布尺寸，添加圖形元件，設(shè)置元件坐標(biāo)和效果。元件閃爍效果，橫向滾動效果。
代碼呈現(xiàn)
圖形元件父類
public class Shape implements IShape{
String shape[];//圖形形狀字符串
String shape_flicker[];//閃爍形狀字符串
int height,width;//高、寬
int x,y;//位置坐標(biāo)
String id;//元件id，用于制作動畫效果時(shí)獲取元件
public Shape(int x,int y,String id) {//構(gòu)造方法初始化
this.x=x;this.y=y;this.id=id;
}
public Shape(String id) {
this(0,0,id);
}
}圖形繪畫工具類
import java.util.HashMap;
public class Shapes {//存放圖形元件
int width,height;//畫布大小
public static String canvas[];//畫布圖像字符串
HashMap<String, Shape> ShapeMap=new HashMap<String,Shape>();//圖形元件容器，添加到畫布的圖形都會存放在這
public Shapes(int width ,int height) {//初始化空白畫布
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) {//將元件添加到畫布中
int px,py;
px=myShape.x;
py=myShape.y;
int count=0;
if(myShape.height+py>height-1) {
System.out.println("超出畫布邊界!!");
return;
}
if(myShape.width+px>width-1) {
System.out.println("超出畫布邊界!!");
return;
}
ShapeMap.put(myShape.id,myShape);//將元件添加到容器中
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() {//繪制畫布
System.out.print(" ");
for(int i=0;i<width;i++) {
System.out.print(i%10);
}
System.out.println();
