env_fade is an e0 available in all Source games. It controls screen fades to or from a solid color. Add Duration and Hold Time together for the total time this entity will be in effect.
Keyvalues
- Duration (seconds) (duration) <string>
- The time that it will take to fade the screen in or out.
- Hold Fade (seconds) (holdtime) <string>
- The time to hold the faded in/out state.
- Fade Alpha (renderamt) <integer>
- Alpha of the fade, where 0 = fully transparent and 255 = fully opaque.
- Fade Color (R G B) (rendercolor) <color255>
- Fade color.
- Reverse Fade Duration (seconds) (ReverseFadeDuration) <float> (in all games since
) - The duration of the reverse fade.
Flags
- Fade From : [1]
- Screen fades from the specified color instead of to it.
- Modulate : [2]
- Uses attenuation blending to achieve the fade. The normal fade does a straight weighted blend between the screen and the fading color. Modulate actually attenuates the RGB channels. For example, a color of
0 255 0would mute the red and blue channels and create a green nightvision-type effect.
- Triggering player only : [4] !FGD
- Only affects the screen of the !activator.
!activatoris probably the easiest to reach through a trigger entity. If not checked, the fade will apply to all players.
- Stay Out : [8]
- Fade remains indefinitely until another fade deactivates it.
Bug:Fades applied to !activator only that are also set to Stay Outwill not be deactivated by a new fade! [todo tested in ?] - Todo: Test in other games, test if the
ScreenFadeVScript function is also affected
Inputs
- Fade
- Start the screen fade.
- FadeReverse (in all games since )
- Begin doing the reverse of the current fade.
- Alpha !FGD
- Changes Fade Alpha.
- Color !FGD
- Changes Fade Color.
Outputs
- OnBeginFade
- Fired when the fade has begun.
ConCommands
Cvar/Command
Parameters or default value
Descriptor
Effect
fadein
float int int int int
Time (seconds), Red, Green, Blue, Alpha
Makes the screen black (or the specified color), then fades to the normal view.
fadeout
float int int int int
Time (seconds), Red, Green, Blue, Alpha
Fades the screen to black (or the specified color).
Bug:Due to mistake in code alpha value isn't read properly from these commands but if you specify rgb it also has to be specified for the fade to work. [todo tested in ?]
