在nodeJS中，假设我有一点In instantiation of 'struct std::atomic<std::pair<int, int> >':
error: static assertion failed: std::atomic requires a trivially copyable type
static_assert(__is_trivially_copyable(_Tp),
：
setInterval它发送给客户实体：
setInterval(() => {
// ...
}, 50)
实体看起来像这样：
setInterval(() => {
socket.emit("entities", { ... })
}, 50)
我如何在每个时间间隔仅发送所有实体的更新属性，并且如果所有实体均未更改，则仅发送{
"0": {
"collisionRadius": 40,
"entityClass": "Prop",
"health": 100,
"maxHealth": 100,
"model": "Tree",
"position": {
"x": 1970,
"y": 1477
},
"uid": 0,
"damage": 10,
"dead": 0,
"height": 32,
"hits": [],
"interpolatedYaw": 0,
"slowed": 0,
"stunned": 0,
"timeDead": 0,
"width": 32,
"yaw": 0
},
"1": {
"collisionRadius": 40,
"entityClass": "Prop",
"health": 100,
"maxHealth": 100,
"model": "Tree",
"position": {
"x": 1240,
"y": 1866
},
"uid": 1,
"damage": 10,
"dead": 0,
"height": 32,
"hits": [],
"interpolatedYaw": 0,
"slowed": 0,
"stunned": 0,
"timeDead": 0,
"width": 32,
"yaw": 0
},
"2": {
"collisionRadius": 40,
"entityClass": "Prop",
"health": 100,
"maxHealth": 100,
"model": "Tree",
"position": {
"x": 2195,
"y": 2034
},
"uid": 2,
"damage": 10,
"dead": 0,
"height": 32,
"hits": [],
"interpolatedYaw": 0,
"slowed": 0,
"stunned": 0,
"timeDead": 0,
"width": 32,
"yaw": 0
}
}
？
接收到的实体应如下所示：
true
