在setTimeout内部和函数内调用一个函数 [英] calling a function inside setTimeout and inside a function

本文介绍了在setTimeout内部和函数内调用一个函数的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

基本上我写了一个函数:


$ b函数animation(){
setTimeout(
function() {
requestAnimationFrame(animation);
if(player.currentFrame == player.frames){
player.currentFrame = 0;
} else {
player.currentFrame ++ ;
}
}
,1000/15);
}

我试图用这段代码调用它
animation( fps);



我试过这样:

 
function animation(fps){
setTimeout(
function(){
requestAnimationFrame(animation);
if(player.currentFrame == player.frames){
player.currentFrame = 0;
} else {
player.currentFrame ++;
}
}
,1000 / fps);
}

并尝试用 animation(30)
但它不起作用。我尝试过这样的搜索主题,但其中没有一个是我想要的。



任何帮助将不胜感激! :

解决方案

您是否尝试过这种语法?

 函数动画(fbs){
requestAnimationFrame(动画);
if(player.currentFrame == player.frames){
player.currentFrame = 0;
} else {
player.currentFrame ++;
}
setTimeout(function(){animation(fbs)},1000 / fbs);
}

我将代码从 setTimeout('animation( fbs)',1000 / fbs); setTimeout(function(){animation(fbs)},1000 / fbs);


basically I have written a function:

function animation(){
    setTimeout(
        function(){
        requestAnimationFrame(animation); 
        if (player.currentFrame == player.frames) {
            player.currentFrame = 0;
            } else {
            player.currentFrame++;
            }
        }
    , 1000 / 15);
}

and I'm trying to call it with this code animation(fps);

I tried making it like this:

function animation(fps){
    setTimeout(
        function(){
        requestAnimationFrame(animation); 
        if (player.currentFrame == player.frames) {
            player.currentFrame = 0;
            } else {
            player.currentFrame++;
            }
        }
    , 1000 / fps);
}

and tried to call it with animation(30) but it didn't work. I tried search topic like this but non of them is excatly what I want.

Any help would be appreciated! :)

解决方案

Did you tried this syntax

function animation(fbs){
        requestAnimationFrame(animation); 
        if (player.currentFrame == player.frames) {
            player.currentFrame = 0;
        } else {
            player.currentFrame++;
        }        
       setTimeout(function(){animation(fbs) }, 1000 / fbs);
}

I changed the code from setTimeout('animation(fbs)', 1000 / fbs); to setTimeout(function(){animation(fbs) }, 1000 / fbs);
