MouseOver CSS3D effect with javascript

2019-03-25 12:43发布

问题:

I am trying to achieve mouseOver effect like this.

I am able to generate css3d matrix required for each and every tile according to their position.

I have achieved this effect with slow mouse movement, but if I am moving fast from one tile to another tile its notupdating properly. its showing gap in between tiles. What is the best way to update all the tile/tile co-ordinates on mouseover so that i get consistent effect?

here is my js code:

 $('.box').each(function() {
            $(this).css('height', '284px');
            $(this).css('width', '284px');
        });

        generateGrid = function(w, h) {
            var t = this;
            this.p = [];
            var d = 30;


            var c = Math.floor($('.w').outerWidth() / 284 + 1);
            var r = Math.ceil($('.w').outerHeight() / 284) + 1;
            var vc = c * r;
            for (i = 0; i < vc; i++) {
                var l = {
                    x: Math.floor(i % c) * 284,
                    y: Math.floor(i / c) * 284
                };
                this.p.push(l);
            }
            var m = m || {};

            m.Grid = function() {
                this.elms = [];
                this.init();
            }, m.Grid.prototype = {
                init: function() {
                    this.createTiles();
                },
                animateTile: function() {
                    var e = this;
                    for (i = 0; i < e.elms.length; i++) {
                        console.log(i);
                        e.elms[i].update();
                    }
                    requestAnimationFrame($.proxy(this.animateTile, this));
                },
                createTiles: function() {
                    var c = this;
                    for (i = 0; i < $('.box').length; i++) {
                        c.elms.push(new m.tile($('.box:eq(' + i + ')'), i));
                    }

                    c.animateTile();
                }
            }, m.tile = function(e, i, pt) {
                this.el = e;
                this.i = i;
                var p = t.p;
                this.elX = Math.floor(i % 4) * 284,
                        this.elY = Math.floor(i / 4) * 284,
                        this.p1 = p[i + Math.floor(i / 4)],
                        this.p2 = p[i + Math.floor(i / 4) + 1],
                        this.p3 = p[i + Math.floor(i / 4) + 6]
                this.p4 = p[i + Math.floor(i / 4) + 5];


                this.init();
            }, m.tile.prototype = {
                init: function() {

                    this.initEvents();
                },
                initEvents: function() {
                    var e = this;
                    var pts = t.p;
                    var p1 = pts[e.i + Math.floor(i / 4)],
                            p2 = pts[e.i + Math.floor(i / 4) + 1],
                            p3 = pts[e.i + Math.floor(i / 4) + 6],
                            p4 = pts[e.i + Math.floor(i / 4) + 5];

                                        y: p4.y - e.elY},
                                ]

            t.grid = new m.Grid();
        };
        generateGrid(284, 284);

BLEND.TransformElement(el,src,dest) in my code gives CSS3D matrix, it's working fine. I need to update vertices properly.

Here is my html and CSS:

<style>
       .box{
            float: left;
            background: #2b5349;
            transform-origin: 0px 0px;
        }
    </style>

    <div class="w" style=" margin-bottom:190px;display:inline-block;width: calc(284px * 4); margin:100px auto;">
        <div class="box" style="background: red"></div>
        <div class="box" style="background: #2b5349"></div>
        <div class="box" style="background: green"></div>
        <div class="box" style="background: blue"></div>
        <div class="box" style="background: darkgoldenrod"></div>
        <div class="box" style="background: fuchsia"></div>
        <div class="box" style="background: lightpink"></div>
        <div class="box" style="background: mediumspringgreen"></div>
        <div class="box" style="background: burlywood"></div>
        <div class="box" style="background: orange"></div>
        <div class="box" style="background: gold"></div>
        <div class="box" ></div>
    </div>

I am doing all this this from start without using any external plugin for that particular effect. Please suggest some solution.

I have stored all the vertices of all tiles and updating it on mouseover. as soon as I mouseover from one tile to another animation for resetting vertices values from new one to original stops. How can I fix vertices update problem on mouseenter and mouseleave envent.

回答1:

I Solved the problem. Problem was with not updating vertices value to the original on mouseout event. to revert vertices value to original question i have to keep extra value of vertices like this.

var l = {
                x: Math.floor(i % c) * 284,
                y: Math.floor(i / c) * 284,
                x2: Math.floor(i % c) * 284,
                y2: Math.floor(i / c) * 284,

            };

On mouseover change the vertice value like this for every coordinate

 TweenMax.to(p1, .3, {
                        x: p1.x2 + d,
                        y: p1.y2 - d,
                        ease: Back.easeOut
                    })

and on mouseout reset original position

 TweenMax.to(p2, .3, {
                        x: p2.x,
                        y: p2.y,
                        ease: Back.easeOut
                    })

Do you have this working for a flexible number of columns. Currently it only seems to work for 4!
