data | 要更新的 NavMeshData。 |
buildSettings | 用于更新 NavMeshData 的构建设置。构建设置也随数据一起进行哈希处理,因此更改设置可能会导致全面重新构建。 |
sources | 用于烘焙的输入几何形状列表,它们描述了要行走的表面或要避开的障碍物。 |
localBounds | 相对于位置和旋转的包围盒,描述了 NavMesh 应构建的体积。 |
AsyncOperation 可用来检查更新的进度。
基于源以异步方式逐渐更新 NavMeshData。(UnityEngine)
每次构建或更新 NavMeshData 时,都会对源数据进行哈希处理,而这些哈希值将随 NavMeshData 一起存储。
调用 UpdateNavMeshDataAsync() 时,首先会比较这些哈希值,然后仅重新构建更改的部分。为此,源列表应始终包含所有输入几何形状,即使它们并未移动或更改。如果在调用 UpdateNavMeshDataAsync 之间修改了源列表,则会将缺失/添加的源视为更改。按以前的相同的相对顺序,尝试提供自上次更新后未更改的源,这是因为其序列会影响哈希值。这个措施可确保未更改的部分不必重新构建。
必须为 localBounds
参数提供一个 Bounds 结构。
