HandleUtility.FindNearestVertex

public static bool FindNearestVertex (Vector2 guiPoint, out Vector3 vertex);

public static bool FindNearestVertex (Vector2 guiPoint, Transform[] objectsToSearch, out Vector3 vertex);

public static bool FindNearestVertex (Vector2 guiPoint, Transform[] objectsToSearch, Transform[] objectsToIgnore, out Vector3 vertex);

参数

guiPoint	A point in GUI space.
vertex	The nearest vertex position to guiPoint, or a default value if no vertex is within the minimum picking distance.
objectsToSearch	An array of Transform to consider when picking the nearest vertex. If null, all active objects in open scenes are considered.
objectsToIgnore	An array of Transform to exclude from consideration when picking nearest vertex.

bool Returns true if a vertex within 50 pixels of the guiPoint was found, false if no vertex found within the minimum picking radius.

Returns the nearest vertex to a guiPoint within a maximum radius of 50 pixels.
