javascript - HTML5 横幅广告中的自动循环 NanoTween 动画

coder 2023-08-12 原文

我希望自动循环我拥有的 HTML5 横幅广告。动画是使用 NanoTween 构建的。这是JS代码:

var container  = getElement("id","container");

var items = {
c1: getElement("id", "copy_1"),
c2: getElement("id", "copy_2"),
c3: getElement("id", "copy_3"),
c4: getElement("id", "copy_4"),
c5: getElement("id", "copy_5"),
c6: getElement("id", "copy_6"),
button: getElement("id", "button"),
elipseOverlay: getElement("id", "elipseOverlay"),
elipseOverlay2: getElement("id", "elipseOverlay2"),
elipse: getElement("id", "elipse"),
elipse2: getElement("id", "elipse2"),
elipseContainer: getElement("id", "elipseContainer"),
bar: getElement("id", "bar"),
magnaclick: getElement("id", "magnaclick"),
shirt: getElement("id", "shirt")
};

function init() {
 setTimeout(function() {
    startAnimation();
}, 5);
};

//
function startAnimation() {
container.style.visibility = "visible";

var delay = 0;
var quickerSpeed = 0.3;

var magnaclick = function() {

            },(idx-1)*(1000/magnaClickFps));
        })(i);
    }
};

var shirt = function() {

        (function(idx){
            setTimeout(function(){

    }
};

    //delay += ((1000/magnaClickFps)*magnaClickFrames/1000);

    //magnaclick last farme static
    items.magnaclick.className = 'sprite2 magnaclick-5';
    NanoTween.to(items.magnaclick, 1, { opacity: 1, ease:easeOutQuad, delay: delay - 0.5});
    NanoTween.to(items.magnaclick, quickSpeed, { transform: 'translate(0px, 10px)', ease:easeInQuad, delay: delay - 0.5});

    // new zoom in
    NanoTween.to(items.c3, quickerSpeed, { opacity: 1, scale: 1, ease:easeInQuad, delay: delay});
    //NanoTween.to(items.c3, quickSpeed, { transform: 'translate(0px, -10px)', ease:easeInQuad, delay: delay});
    delay += quickerSpeed + 0.2; // + pause

    // magnetic buttons fade in
    NanoTween.to(items.c4, quickSpeed, { opacity: 1, ease:easeInQuad, delay: delay});
    //NanoTween.to(items.c4, quickSpeed, { transform: 'translate(0px, -10px)', ease:easeInQuad, delay: delay});

    // pause
    delay += quickSpeed + 0.5;

    // copy fades out
    NanoTween.to(items.c3, mediumSpeed, { opacity: 0, ease:easeOutQuad, delay: delay});
    NanoTween.to(items.c4, mediumSpeed, { opacity: 0, ease:easeOutQuad, delay: delay});
    // shirt fades in

animate();

}

function getElement(element, id) {
var mc;
switch(element){
    case "id":
        mc = document.getElementById(id);
        break;

    case "class":
        mc = document.getElementsByClassName(id);
        break;
}

return mc;
}


window.onload = function(){
init();
};

在最后一帧短暂暂停后，是否可以添加代码以自动循环此动画？如果可能，请告诉我。感谢您的帮助!

最佳答案

这可以通过在最后一次 NanoTween 调用之后添加以下内容来完成。循环将暂停 3.6 秒 (var pause = 3.6;)，然后重新开始。

// the last Tween ran for this duration, so we need to include to get the total duration
delay += quickerSpeed; 

setTimeout(function() {
    delay = 0; // reset animation total duration counter
    animate(); // begin again
}, (delay + pause) * 1000); // Convert delay & pause to milliseconds & restart once time has elapsed

以下是包含上述更改的完整代码:
