getClosestRegion

该函数是Yuka js库中NavMesh类的一个方法,用于获取最接近给定点的NavMesh区域。

参数

  • point:Vector3类型参数,表示要查找的点的位置。

返回值

  • 返回值是NavMeshRegion类型,表示最接近给定点的NavMesh区域。

使用示例

// 创建NavMesh对象
let navMesh = new NavMesh();

// 为NavMesh添加区域
navMesh.addRegion(new NavMeshRegion(vertices, connections));

// 获取最接近给定点的NavMesh区域
let closestRegion = navMesh.getClosestRegion(point);

实现原理

该函数实现的原理是遍历NavMesh中的所有区域,并计算每个区域与目标点之间的距离。最后返回距离最近的区域。

注意事项

  • 如果NavMesh中没有任何区域,则该函数返回null。
  • 如果给定点位于NavMesh外部,则该函数返回null。
