我正在构建一个游戏
当用户单击鼠标右键时我需要做一些事情,holds it然后按左键
我怎样才能检测到这种行为?

var rightMouseClicked = false;
function handleMouseDown(e) {
//e.button describes the mouse button that was clicked
// 0 is left, 1 is middle, 2 is right
if (e.button === 2) {
rightMouseClicked = true;
} else if (e.button === 0) {
//Do something if left button was clicked and right button is still pressed
if (rightMouseClicked) {
console.log('hello');
//code
}
}
console.log(rightMouseClicked);
}
function handleMouseUp(e) {
if (e.button === 2) {
rightMouseClicked = false;
}
console.log(rightMouseClicked);
}
document.addEventListener('mousedown', handleMouseDown);
document.addEventListener('mouseup', handleMouseUp);
document.addEventListener('contextmenu', function(e) {
e.preventDefault();
});
