我一直在看很多不同的教程,学习我一直在做的编码,我注意到了一个常见的区别.基本上,有些人纯粹使用HTML编写脚本,使用脚本标记,有些人使用JavaScript并引用脚本.我的问题在于两个代码.第一个:

<!DOCTYPE html>
<html>
    <head>
        <script src='babylon.js'></script>
        <title>game or some shit</title>
        <meta charset="utf-8">
        <style>
            .canvas {
                height: 100%;
                width: 100%;

            var canvas = document.getElementById('gamecanvas');
            var engine = new BABYLON.Engine(canvas, true);
            var scene = new BABYLON.Scene(engine);
            var camera = new BABYLON.ArcRotateCamera('camera', 1,2,20, new BABYLON.Vector3(0,0,0), scene);
            var light = new BABYLON.PointLight('light', new BABYLON.Vector3(0,0,10), scene);
            var ball = new BABYLON.Mesh.CreateSphere('ball', 10, 1.0, scene);

            scene.activeCamera.attachControl(canvas);
            engine.runRenderLoop(function()
            {
                scene.render();
            });
