0x49 — LANDSCAPE_POS

Reads a group byte and an x,y,z float vector, resolves the landscape from gpBackGround (slot arg&3), then calls CRadiLandscape::GetGroupHeader and CRadiLandscape::SetPosition.

traced— handler traced, but no shipped script uses this opcode, so the operand layout rests on the trace alone with no real data to check it against.

Handler behaviour

Reads a group byte and an x,y,z float vector, resolves the landscape from gpBackGround (slot arg&3), then calls CRadiLandscape::GetGroupHeader and CRadiLandscape::SetPosition.

Encoding

The command header is one 32-bit word, as described in §3 Instruction encoding:

 31            24 23            16 15             8 7              0
+----------------+----------------+----------------+----------------+
|  flags         |  argument byte |  extra words   |  0x49          |
+----------------+----------------+----------------+----------------+

Bits 8–15 give the number of 32-bit operand words that follow. Bits 16–23 are handed to the handler as a bitfield; on character commands bit 0 normally says whether a character selector word is present. Bit 31 is the keep-going bit.

Engine calls

Engine functions this handler was observed calling:

  • CRadiLandscape::GetGroupHeader
  • CRadiLandscape::SetPosition
