Making a Camera with a monitor
Let's make a camera and have
it show on a monitor.
The entity's used are a Point_camera
entity, info_camera_link entity, a func_monitor
brush entity,
func_button brush entity.
First build your map and a place to build your monitor.
Then place the point_camera
and info_camera_link entities around your
map in the areas you want shown on monitor.
Point_camera entity in the properties window
you will have to name it (example:
cam2a), you can also change
the FOV(field of view) to different degrees. Under the Flags
option check off the "
Start Off "
box if you have multiple cameras around your map,except
for the first camera in the rotation.
Info_camera_link entity in
the properties window you will have to enter the name
of the monitor
in the Entity Whose Material Uses_rt_cam
parameter.(example: monitor).
Then in the camera name parameter enter the
name of the camera (example:
cam2a)
Next let's make some buttons to switch the monitor views. Func_buttons
that is.
Make a button out of a brush, then hit the "To Entity" button
and tie the brush to a func_button.
Then in the properties window of the func_button
go to the Outputs Tab and click on the Add...
button at bottom, on My output named click
the drop down menu and select OnPressed ,
Then the Targets entities named select your
camera name Camera name.(Example:
cam2a).
Then the Via this input select Set
On And Turn Others Off.
Under the Flags tab you can select some other
options like Use Activates and Don't
Move.
Now you can build your monitor. Make another brush (the
brush you want the view of the cameras on)
and hit the "To Entity" button
and make it a func_monitor. In
the properties window name it the
name of your monitor (Example: monitor)
Now highlight the brush and place a Dev_Monitor
texture
on the face you want the picture on. Use the Texture
Application Tool to do this.
Browse for texture name by typing key word in filter box. (Filter
word: monitor).
As you can see below the dev_monitor textures look weird in Hammer, but
show up properly in game.
If you have more than one camera, just make additional Point_camera,
info_camera_link
and func_button entities. naming each set
of camera entites different.
Some in game screenshots:
Another Image......... Another
Image <--this image has a different dev_monitor texture on it.
As you can see from the screenshot of dev_monitor textures,
there are different types of monitor
effects you can get.Apply the textures and compile the map to see the
differences.
*On a side note , you can not see your self in the
monitor view.
