Indicates the beginning of a cell update.
This event is triggered only in response to a call to aw_query. This event will be followed by zero or more AW_EVENT_CELL_OBJECT events and one AW_EVENT_CELL_END event.
The following attributes are valid during the context of this event:
AW_CELL_X
AW_CELL_Z
AW_CELL_SEQUENCE
AW_CELL_SIZE
AW_CELL_X and AW_CELL_Z specify the coordinates of the cell that is being updated. AW_CELL_SEQUENCE is the sequence number for this cell. The sequence number for the last cell in a sector is the new sequence number for that sector. AW_CELL_SIZE is the size in bytes of the entire cell update message (note: this is not necessarily the same as the size of the cell data as it relates to the world's current cell data limit.)
See Property for a description of the property query mechanism.
See Sample Program #2 for a complete example.
