Variables

  Type Name Description
Public variable FHashTable IndexMap Bookkeeping arrays
Public variable TSparseArray< FBuoyancyInteractionArray > Interactions Sparse array of arrays of buoyancy interactions - the outer array has one entry per particle, the inner array has an entry per water body that it interacts with.
Public variable TSparseArray< FBuoyancySubmersionMetaData > PrevSubmersionMetaData  
Public variable TSparseArray< FBuoyancySubmersion > PrevSubmersions  
Public variable TSparseArray< int32 > ReverseIndexMap  
Public variable TSparseArray< TBitArray<> > SubmergedShapes This is a sparse array of bit arrays representing which shapes in an object have already been accounted for when submerging an object.
Public variable TSparseArray< FBuoyancySubmersionMetaData > SubmersionMetaData Another sparse array to be kept in sync with Submersions, which will contain metadata useful for event callbacks
Public variable TSparseArray< FBuoyancySubmersion > Submersions This sparse array of submersion events is indexed on particle unique indices.
