我想知道如何在实体上设置纹理，但仅在该实体上设置纹理，然后通过选择纹理按钮放置更多纹理，我无法使代码正常工作，但我想使其功能更像《我的世界》比原始《我的世界》框架演示更胜一筹。如果有人可以使我的代码正常工作，那将是真正的帮助。所有被注释掉的脚本是因为我想找到一种更好的方法来做我想做的事情。本质上，我想在底部的菜单中选择一个纹理，然后在我的实体上使用该纹理。

答案 0 :(得分：0)
切换纹理可以通过两种方式完成
aframe原语（例如<a-box>或<a-sphere>实体）很简单。只需更改material.src属性
el.setAttribute('material', 'src', newTexture)
模型可能很难处理，因为您需要切换mesh.map.texture属性（可能在所有子对象上，而不仅仅是在一个网格上）。
var mesh = this.el.getObject3D('mesh')
var loader = new THREE.TextureLoader();
loader.load( url, (texture) => {
// onLoad callback
mesh.material.map = texture
mesh.material.needsUpdate = true
this.switch = !this.switch
}
)
起初，我想存储有关纹理的信息，并在单击<a-box>时访问它，但是一种简单的方法是拥有几张图像
<img class=".images" ....>
<img class=".images" ....>
以及每个无框架原语上的一个组件，该组件将是：
检测这些图像上的点击->存储信息->单击我们时使用它：
检测图像上的点击：
var els = document.getElementsByClassName("images");
Array.from(els).forEach((el) => {
el.addEventListener('click', (e)=>{
this.selectedTexture = e.target.src
})
});
点击时应用纹理：
this.el.addEventListener('click', (e) => {
if (!this.selectedTexture) {
return
}
this.el.setAttribute("material", "src", this.selectedTexture)
})
This fiddle包含以上所有内容。有两个框可以自己切换纹理，其余的将应用所选图像作为纹理。
