Daggerfall Mod:DFRemake/DFEGetNextRegionLocation

integer DFEGetNextRegionLocation ( DWORD MemblockPtr, DWORD RegionIndex )

Inputs

• MemblockPtr: Pointer to the memblock (from GET MEMBLOCK POINTER) to receive the location data. The memblock should be allocated with at least 256 bytes.
• RegionIndex: The region index to start iterating locations in.

Outputs

Returns 0 if there are no more locations in the given region (or on any error). Returns 1 on success.

Description

Use this function to continue iterating through all locations in a given region after an initial call to DFEGetFirstRegionLocation. The memblock format is as follows:

Field	Type	Byte Pos	Description
XPos	float	0	X position of the location in the world
YPos	float	4	Y position of the location in the world
Type	DWORD	8	Type of location (see Location Types).

Example

  Local Result as integer
  Local XPos   as float
  Local YPos   as float
  Local Type   as DWORD

  make memblock 1, 256
  Result = DFEGetFirstRegionLocation(get memblock ptr(1), 19)

  while (Result)
     XPos = memblock float(1, 0)
     YPos = memblock float(1, 4)
     Type = memblock DWORD(1, 8)

     print "Found location at ", XPos, ", ", YPos, " of type ", Type

     Result = DFEGetNextRegionLocation(get memblock ptr(1), 19)
  endwhile
