我这里没有代码,所以我希望你能理解,我回家后编辑和添加代码。
我已经建立了一个类移动,一旦初始化就会向渲染的 dom 元素添加一个 jquery 事件(keyDown)。
该事件检查开关盒中的键是什么,
如果键是其中一种情况,则相机将相应移动。
相机确实移动了,但由于某种原因,它有点闪烁,就像小跳一样。每个摄像机移动的速度为 0.05;
当我在另一个应用程序中执行此操作但通过主脚本中的 javascript keydown 事件(无特殊类)时,它运行良好..
知道为什么要这样做吗?
编辑:代码
主脚本:
<script>
var moveMec = null;
var loopProg = null;
var renderer = null;
var scene = null;
var camera = null;
var mesh = null;
var earth = null;
var sun = null;
$(document).ready(
function() {
var container = document.getElementById("container");
renderer = new THREE.WebGLRenderer({ antialias: true } );
renderer.setSize(container.offsetWidth,container.offsetHeight);
container.appendChild(renderer.domElement)
scene = new THREE.Scene();
camera = new THREE.PerspectiveCamera( 45,
container.offsetWidth / container.offsetHeight, 1, 4000 );
earth = new Earth();
sun = new Sun({x:-10,y:0,z:20});
scene.add(earth.getEarth);
scene.add(sun.sunLight);
camera.position.set( 0, 0, 3 );
moveMec = new moveMechanics(camera,renderer.domElement)
loopProg = new loopProgram();
loopProg.add(function(){earth.update()});
//loopProg.add(function(){renderer.render( scene, camera );});
loopProg.solarLoop();
}
);
</script>
移动脚本:
var moveMechanics = function (camera,domElement,speed)
{
moveMechanics.camera = camera;
moveMechanics.speed = speed != undefined ? speed : 0.01;
moveMechanics.domElement = domElement;
$(document).keydown(function(event)
{
switch(event.which)
{
case KeyEvent.DOM_VK_W:
camera.position.z -= moveMechanics.speed;
break;
case KeyEvent.DOM_VK_S:
camera.position.z += moveMechanics.speed;
break;
case KeyEvent.DOM_VK_D:
camera.position.x += moveMechanics.speed;
break;
case KeyEvent.DOM_VK_A:
camera.position.x -= moveMechanics.speed;
break;
}
});
}
循环代码:
function loopProgram()
{
this.functionsToRun = new Array();
this.solarLoop= function()
{
jQuery.each(loopProg.functionsToRun, function(index,value)
{
value ? value() : null;
});
requestAnimationFrame(loopProg.solarLoop);
}
this.add = function(func)
{
this.functionsToRun[this.functionsToRun.length] = func;
}
}
