Question

这个问题是团结中的一般性问题c＃我知道我不能有多个网格过滤器但我在脚本中生成了更多的那个网格，我想让它们在一个对象中一次渲染，但我不想合并顶点数组，所以我仍然可以动态删除面孔

基本思想是将体素作为一个游戏对象，但是由脚本构成不同的面孔我想保持面部可访问而不进入一个巨大的阵列

所以现在我有6个面孔作为网格，我不知道如何渲染它们

最好的方法是什么，/最佳方式去/ / noob

Answer 1

所以我有一些答案，但仍需要有关概念方法的指导所以我重写了我的“体素”，但现在我正在考虑编写一系列功能来“破坏”面部，如果他们不需要，但问题是，如果我把我的三角形（我认为这是最简单的）全部为0 0 0，它不像释放任何内存，它只是不可见，所以它不是好的方式去

怎么会有人去做某种优化的体素？

我想从我的代码中你知道我是初学者

我可以在发送到网格过滤器之前将网格添加到一起c＃
