接下來,我們需要創建一個GUI工具箱,用于修改場景的各種屬性,例如光線、速度等等。具體的代碼如下:3D Mazes
然后,我們需要定義迷宮的墻壁和地板對象。我們使用BoxGeometry創建一個立方體,并為其添加紋理材質。具體的代碼如下:var controls = new function() { this.lightLevel = 1; this.speed = 0.3; } var gui = new dat.GUI(); gui.add(controls, 'lightLevel', 0, 2); gui.add(controls, 'speed', 0, 1);
最后,我們需要添加一個光源和一個動畫循環,來讓場景動起來。具體的代碼如下:var wallTexture= new THREE.TextureLoader().load( 'https://raw.githubusercontent.com/mrdoob/three.js/dev/examples/textures/brick_diffuse.jpg' ); wallTexture.wrapS = wallTexture.wrapT = THREE.RepeatWrapping; var wallMaterial = new THREE.MeshBasicMaterial( { map: wallTexture, side: THREE.DoubleSide } ); var wallGeometry = new THREE.BoxGeometry(10,10,1); var ceilingGeometry = new THREE.BoxGeometry(10,10,1); var wall, ceiling for(var i=0; i<10; i++) { wall = new THREE.Mesh(wallGeometry, wallMaterial); ceiling = new THREE.Mesh(ceilingGeometry, wallMaterial); wall.position.z = (i * 10) - 45; ceiling.position.z = (i * 10) - 45; scene.add(wall); scene.add(ceiling); } for(var j=1; j<10; j++) { wall = new THREE.Mesh(wallGeometry, wallMaterial); ceiling = new THREE.Mesh(ceilingGeometry, wallMaterial); wall.rotation.y = Math.PI/2; ceiling.rotation.y = Math.PI/2; wall.position.x = (j * 10) - 45; ceiling.position.x = (j * 10) - 45; scene.add(wall); scene.add(ceiling); }
至此,我們已經成功創建了一個HTML5 3D迷宮代碼。這個迷宮代碼可以讓使用者調整光線和速度,移動相機來探索這個迷宮。HTML5技術的應用,讓這個迷宮代碼非常有趣和互動。var light = new THREE.PointLight( 0xffffff, controls.lightLevel, 0 ); light.position.set( 0, 0, 0 ); scene.add( light ); var clock = new THREE.Clock(); var animate = function () { var delta = clock.getDelta(); var moveDistance = delta * controls.speed; renderer.render(scene, camera); requestAnimationFrame(animate); }; animate();
