func_monitor
is a brush entity available in all Source and Source 2 games except Left 4 Dead series. It displays a real-time scene captured from a point_camera somewhere else in the world.
In Source for the entity to work, the surface(s) on which the camera view will be displayed must have a material with $basetexture _rt_Camera
. Stock materials that work are dev\dev_combinemonitor*
and dev\dev_tvmonitor*
.
Bug:Cameras may fail to network properly in multiplayer. See below for a code fix. Fixed in Team Fortress 2. [todo tested in ?]
Note:Unless you set up multiple render textures in your mod's binaries, only one point_camera can be rendered at any one time. The first camera in the map will appear on all monitors. Multiple cameras at once are technically possible, as long as you ensure that only one func_monitor is in the PVS at any given time, although this will not work in splitscreen (but will work in online multiplayer).
Code:To enable monitors in your non-HL2 mod, you must:
- Include the entity's client .cpp file (found in
\client\hl2\
). - Include the entity's server .cpp and .h files (found in
\server\hl2\
). #define USE_MONITORS
at the top of\client\viewrender.cpp
and\client\view.cpp
.- Fix a multiplayer bug in
CPointCamera::CPointCamera()
by settingm_bActive
to true.
