承诺说他们完成了，但他们没有？
Promises say they are done when they are not?
我有一个浏览器游戏，它必须在开始前加载一些东西。我把所有的加载都封装成两个promise。
var promise1 = new Promise(function(resolve, reject) { ...loading stuff here... resolve() });
var promise2 = new Promise(function(resolve, reject) { ...loading stuff here... resolve() });
然后我在下面放了一个启动游戏循环的函数
Promise.all([promise1, promise2]).then(setInterval(GameLoop, time));
编辑：在上面的代码中添加 () => 并没有解决问题。
问题是，虽然一切都启动并运行良好，但在加载所有内容之前它仍然会抛出四帧错误。我认为 promises 应该等到它们内部的代码完成它的事情。
我不太确定出了什么问题。可能我错过了关于 javascript 的一些基本知识。浏览器没有抛出任何错误，只是它在开始时找不到 4 - 5 帧的变量。

和
Promise.all([promise_loadClient, promise_loadManager]).then( () => setInterval(GameLoop, step) );
setInterval 正在立即执行。尝试将该代码放在传递给 .then:
的函数中
Promise.all([promise1, promise2]).then(() => setInterval(GameLoop, time));
我误解了承诺。
在 promise 内的异步函数完成之前调用 Resolve，这反过来意味着 promise 比预期提前完成。
基本上我之前的每一个承诺都是：
var promise1 = new Promise ((resolve, reject) => {
function irrelivantfunction1 (){
// things
}
async function importantfunction1 (){
// things
}
function irrelivantfunction2 (){
// things
}
async function importantfunction2 (){
// things
}
resolve()
})
但应该是：
function irrelivantfunction1 (){
// things
}
var promise1 = new Promise ((resolve, reject) => {
async function importantfunction1 (){
// things
resolve();
}
});
function irrelivantfunction2 (){
// things
}
var promise2 = new Promise ((resolve, reject) => {
async function importantfunction1 (){
// things
resolve()
}
});
每个异步函数一个。并且，最后这样解决：
Promise.all([promise1, promise2]).then(() => setInterval (GameLoop, time));
此外，将'() =>'添加到设置的间隔，否则它将立即运行。
我有一个浏览器游戏，它必须在开始前加载一些东西。我把所有的加载都封装成两个promise。
var promise1 = new Promise(function(resolve, reject) { ...loading stuff here... resolve() });
var promise2 = new Promise(function(resolve, reject) { ...loading stuff here... resolve() });
然后我在下面放了一个启动游戏循环的函数
Promise.all([promise1, promise2]).then(setInterval(GameLoop, time));
编辑：在上面的代码中添加 () => 并没有解决问题。

和
Promise.all([promise_loadClient, promise_loadManager]).then( () => setInterval(GameLoop, step) );
setInterval 正在立即执行。尝试将该代码放在传递给 .then:
Promise.all([promise1, promise2]).then(() => setInterval(GameLoop, time));
我误解了承诺。
在 promise 内的异步函数完成之前调用 Resolve，这反过来意味着 promise 比预期提前完成。
基本上我之前的每一个承诺都是：
var promise1 = new Promise ((resolve, reject) => {
function irrelivantfunction1 (){
// things
}
async function importantfunction1 (){
// things
}
function irrelivantfunction2 (){
// things
}
async function importantfunction2 (){
// things
}
resolve()
})
但应该是：
function irrelivantfunction1 (){
// things
}
var promise1 = new Promise ((resolve, reject) => {
async function importantfunction1 (){
// things
resolve();
}
});
function irrelivantfunction2 (){
// things
}
var promise2 = new Promise ((resolve, reject) => {
async function importantfunction1 (){
// things
resolve()
}
});
每个异步函数一个。并且，最后这样解决：
Promise.all([promise1, promise2]).then(() => setInterval (GameLoop, time));
此外，将'() =>'添加到设置的间隔，否则它将立即运行。
