0x48 — landscape_visibility

Landscape group visibility helper. It calls CRadiLandscape::GetGroupHeader, then toggles the group hidden bit and calls CHierarchicalObject::SetVisibility.

Handler behaviour

Landscape group visibility helper. It calls CRadiLandscape::GetGroupHeader, then toggles the group hidden bit and calls CHierarchicalObject::SetVisibility.

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   |  0x48          |
+----------------+----------------+----------------+----------------+

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.

Operand fields

4 documented fields. input fields are read from the command's operand words; derived fields are computed from other fields rather than stored separately.

Field	Role	Meaning
`group`	input	Which group the target belongs to.
`hidden`	derived	Hidden bit toggled on the landscape group header.
`slot`	input	Index into a runtime table owned by this command's subsystem.
`visible`	input	Visibility boolean passed to CHierarchicalObject::SetVisibility.

Engine calls

Engine functions this handler was observed calling:

CHierarchicalObject::SetVisibility(float)
CRadiLandscape::GetGroupHeader(int,int,RADILANDSCAPEHEAD**)

Bit masks

Masks the handler applies to its argument byte or operand words:

0x0003 0x0001 0x7FFF 0xFFBF
