Javascript 设置数组中存储的three.js对象的位置
每次调用animate函数时，我都试图在x轴+1上移动我的对象，但我一直遇到无法读取未定义属性x的错误 因此，每次我向场景添加网格时，我都会将其添加到SceneObject数组中 像这样Javascript 设置数组中存储的three.js对象的位置,javascript,three.js,game-engine,Javascript,Three.js,Game Engine,每次调用animate函数时，我都试图在x轴+1上移动我的对象，但我一直遇到无法读取未定义属性x的错误 因此，每次我向场景添加网格时，我都会将其添加到SceneObject数组中 像这样 addToGlScene(mesh, 'player') 使用此函数 function addToGlScene(what, name, glow, storage){ glScene.add(what) what.name = name sceneOb

如果场景对象['player'].position在animate函数中未定义，则说明存在其他问题。我自己发现了这个问题：我不断收到未定义错误的原因是因为我调用了控制台。logsceneObjects['player'].position在动画函数中，该函数在加载页面时立即启动，而所有模型尚未加载，因此我使用tree.js仅在加载所有对象后调用动画函数，该函数工作正常如果可以添加代码、结构。。。我们可以看一些东西：很抱歉，我构建了它：在不知道诸如console.logsceneObjects['player']和sceneObjects['player']的信息的情况下，很难识别问题。位置？请显示代码。您没有在动画函数中引用场景对象。如果网格类型！=“未定义”将始终跳过，除非在“动画”上方的范围中定义了网格。在我们深入讨论这个问题之前，我认为您需要后退一步，创建一个展示相同问题的最小示例，并将其发布在这里，这样我们就可以更好地调试整个问题，而不是策划代码块。我只是不明白为什么要做sceneObject['player'].position.x=+1如果我在控制台时可以看到它，则无法工作。记录'sceneObject['player']并查看所有对象信息这是正确的。更新Object3D的位置值将移动对象，但如果它说位置未定义，则问题在于代码中的其他地方，我们需要查看动画函数的外观。
