NearbySearchOrderedPosMap< T >()

static bool Terraria.ModLoader.PosData< T >.NearbySearchOrderedPosMap< T > ( PosData< T >[] posMap, Point pt, int distance, out PosData< T > entry )

inlinestatic

Searches around the provided point to check for the nearest entry in the map for OrdereredSparse data Doesn't work with 'compressed' lookups from T:Terraria.ModLoader.PosData`1.OrderedSparseLookupBuilder

Parameters

posMap
pt
distance	The distance between the provided Point and nearby entry
entry

Returns

True if successfully found an entry nearby
