设置体素大小（以世界长度为单位）。
构建导航网格时，需要先对场景进行体素化，然后从场景的体素化表示形式中确定可行走空间。体素大小以世界单位表示，控制着导航网格与场景的几何体的贴合程度。
如果您需要更多细节，使导航网格更贴近场景的几何体，可以缩小体素大小。细节的增加也会导致游戏消耗更多内存，并延长导航网格数据的计算时间。缩放比例约为二次方，因此分辨率加倍会导致构建时间延长至之前的大约四倍。
一般情况下，每个角色的直径应在 4-6 体素之间。例如，如果场景中的角色的半径为 0.3，则体素大小最好为 0.1。默认值为 agentRadius 的三分之一。
注意：如果您想使用此设置，还必须将 overrideVoxelSize 设置为 true。
