检测两个fill.Rect函数之间的碰撞

我有一个游戏，其中一个玩家由箭头键控制，另一个玩家由WSAD键控制。我在一个600x600的画布中设置了地图，并希望在游戏中的两个fill.Rect玩家之间添加碰撞，当两个玩家在一定半径范围内时，要么结束程序，要么显示文本，如“游戏结束”

以下是我的js、Html和Css代码（要查看代码片段，您必须转到“全屏”）：

//Canvas
mycan.style.display = "block";
mycan.height = 600;
mycan.width = 600;
//make players
let player = {x:511, y: 541, w:29, h:29};
let player2 = {x:60, y:31, w:30, h:29};


//Context
const ctx = mycan.getContext("2d");


//Start-position
ctx.fillRect(player.x, player.y, player.w, player.h);
ctx.fillRect(player2.x, player2.y, player2.w, player2.h);
//No-smooth-movement
window.onkeydown = move = (e) => {
    let key = e.keyCode;
  //player1(red)
    if     (key === 68 && player2.x <= mycan.width-30) {player2.x += 30;} //right
    else if(key === 65 && player2.x >= 10) {player2.x -= 30;} //left
    else if(key === 83 && player2.y <= mycan.height-30) {player2.y += 30;} //down
    else if(key === 87 && player2.y >= 10) {player2.y -= 30;} //up  
  
  
  //player2(blue)
    if     (key === 39 && player.x <= mycan.width-25) {player.x += 30;} //right
    else if(key === 37 && player.x >= 10) {player.x -= 30;} //left
    else if(key === 40 && player.y <= mycan.height-25) {player.y += 30;} //down
    else if(key === 38 && player.y >= 10) {player.y -= 30;} //up
}

const draw = ()=>{
//player draw, and player colors
  ctx.clearRect(0,0, mycan.width, mycan.height);
  ctx.fillRect(player.x, player.y, player.w, player.h);
  ctx.fillStyle = "blue";
  ctx.fillRect(player2.x,player2.y, player2.w, player2.h);
  ctx.fillStyle = 'red';
  
  
  
};

setInterval(()=>{
  draw();
},1000/60);

//collision
//thsi is where i want to add collision

html, body {
  margin:20;
  padding: 20;
}
canvas {
  display: block;
}

#mycan {
  background-size: 30px 30px;
  background-image:
    linear-gradient(to right, black 1px, transparent 1px),
    linear-gradient(to bottom, black 1px, green 1px);

}
