[英]How to change the value of Variable in setInterval
the Value of time will change just one time in the method setInterval i would like to change it with the value of checkLevel时间值在 setInterval 方法中只会改变一次我想用 checkLevel 的值来改变它
var time = checkLevel(); var time = checkLevel();
//die Methode wird nach msecLevel aufgerufen //die Methode wird nach msecLevel aufgerufen
setInterval(function (event) {
time = checkLevel();
if (!isLoser) {
//Leere die Fläche
ctx.clearRect(0, 0, canvasWidth, canvasHeight);
//Neu durchführen
randomX = getRandomPosition(canvasWidth - fishSize);
randomY = getRandomPosition(canvasHeight - fishSize);
var randomFish = Math.floor(Math.random() * 11) + 1;
fish.src = 'images/fish' + randomFish + '.png';
}
}, time);
You can create a recursive function that changes the interval, then simply call the interval once to start it, then the function will just change the interval every call.您可以创建一个更改间隔的递归函数,然后只需调用一次间隔即可启动它,然后该函数将在每次调用时更改间隔。
var _timer;
function showFish(){
if (!isLoser) {
//Leere die Fläche
ctx.clearRect(0, 0, canvasWidth, canvasHeight);
//Neu durchführen
randomX = getRandomPosition(canvasWidth - fishSize);
randomY = getRandomPosition(canvasHeight - fishSize);
var randomFish = Math.floor(Math.random() * 11) + 1;
fish.src = 'images/fish' + randomFish + '.png';
}
_timer = setTimeout(showFish, checkLevel());
}
_timer = setTimeout(showFish, checkLevel());
