Question

大家好，我正在尝试实现碰撞功能，因此，如果猴子碰到香蕉，香蕉就会移动到画布周围的某个地方。

目前，猴子和椰子在四处移动，猴子和香蕉相撞，但是香蕉之后没有移动。

这是功能：

var mx = canvas.width / 2;     
var my = canvas.height / 2;
var mdx = 0;        
var mdy = 0;
var mspeed = 2;        
var mlives = 3; 
var cx = 400;
var cy = 250;
var cspeed = 3;
var cdx = cspeed - 1;
var cdy = cspeed;
var bx = Math.floor(Math.random() * canvas.width);
var by = Math.floor(Math.random() * canvas.height);
var bananasEaten = 0;
var lives = 3;
var rightPressed = false;
var leftPressed = false;
var upPressed = false;
var downPressed = false;

function getBanana() {
    if (mx <= (bx + bananaImage.width) && bx <= (mx + monkeyImage.width)) {
        if (my <= (by + bananaImage.height) && by <= (my + monkeyImage.height)) {
             bananasEaten = bananasEaten + 1;
             bx = Math.floor(Math.random() * (canvasWidth - bananaImage.width));
             by = Math.floor(Math.random() * (canvasHeight - bananaImage.height));
         }
    }
}

因此，基本上，您想检查一下猴子（mx，my）的位置是否与香蕉（bx，by）的位置匹配。因此：

尽管，我应该提一下，您可能需要将此if( mx + monkey.width >= bx && mx <= bx + banana.width && my + monkey.height >= by && my <= by + banana.height) { // Execute code }函数放在另一个绘制游戏的函数中，该函数通过getBanana或setInterval一遍又一遍地被调用，因为我猜这是一些游戏。
