Object-oriented implementation of a simple version of Super Mario mini-game
Object-oriented implementation of a simple version of Super Mario mini-game
Using object-oriented thinking to design a simplified version of Super Mario game characters (schematic diagram) 
Analysis of the game:
(1) See how to control mario’s position through buttons
(2) Design related objects (mario, obstacles, etc.)
Small game functions:
(1) Control mario’s movement through the keyboard;
(2) There will be a prompt message when mario hits the boundary ;
(3) Mario will prompt a message when he finds the treasure;
Emphasize the key points and provide the source code:
html code:
<!DOCTYPE html>
<html>
<head>
<link href="mario.css" type="text/css" rel="stylesheet"/>
<script language="javascript" type="text/javascript">
function Mario(){
this.x=0;
this.y=0;
//移动 0->上 1->左 2->右 3->下
this.move=function(direct){
switch(direct){
case 0: //这里为了改变img的left和top，我们需要得到img元素(对象)
var mymario=document.getElementById('mymario');
var top=mymario.style.top;
top=parseInt(top.substr(0,top.length-2));
var left=mymario.style.left;
left=parseInt(left.substr(0,left.length-2));
newtop=top-10;
if(newtop==-10){
window.alert("已到达上边界");
} else{
mymario.style.top=(newtop)+"px";
} if(newtop==460&&left==610){
window.alert("mario找到宝箱啦")
} break;
case 1:
var mymario=document.getElementById('mymario');
var left=mymario.style.left;
left=parseInt(left.substr(0,left.length-2));
var top=mymario.style.top;
top=parseInt(top.substr(0,top.length-2));
newleft=left-10;
if(newleft==-10){
window.alert("已到达左边界")
} else{
mymario.style.left=(left-10)+"px";
} if(top==400&&newleft==660){
window.alert("mario找到宝箱啦")
} break;
case 2:
var mymario=document.getElementById('mymario');
var left=mymario.style.left;
left=parseInt(left.substr(0,left.length-2));
var top=mymario.style.top;
top=parseInt(top.substr(0,top.length-2));
newleft=left+10;
if(newleft==760){
window.alert("已到达右边界")
} else{
mymario.style.left=(left+10)+"px";
} if(top==400&&newleft==570){
window.alert("mario找到宝箱啦")
} break;
case 3:
var mymario=document.getElementById('mymario'); var top=mymario.style.top;
top=parseInt(top.substr(0,top.length-2));
var left=mymario.style.left;

} else{
mymario.style.top=(top+10)+"px";
} if(newtop==360&&left==610){
window.alert("mario找到宝箱啦")
} break;
}
}
} //创建Mario对象
var mario=new Mario();//全局函数
也可以去掉这个全局函数直接在onclick调用对象方法mario.move();
function marioMove(direct){
switch(direct){
case 0:
mario.move(direct);
break;
case 1:
mario.move(direct);
break;
case 2:
mario.move(direct);
break;
case 3:
mario.move(direct);
break;
}
}

How to implement exact division operation in Golang
Feb 20, 2024 pm 10:51 PM
Implementing exact division operations in Golang is a common need, especially in scenarios involving financial calculations or other scenarios that require high-precision calculations. Golang's built-in division operator "/" is calculated for floating point numbers, and sometimes there is a problem of precision loss. In order to solve this problem, we can use third-party libraries or custom functions to implement exact division operations. A common approach is to use the Rat type from the math/big package, which provides a representation of fractions and can be used to implement exact division operations.
