l4d2=1 shows inputs that are for l4d2 only. Similar ones are in CSGO, but they do not work!preasw=1 hides SetAnimationNoReset and FadeAndKill.CDynamicProp:
SetAnimation <string>- Forces the prop to play the named animation.
SetDefaultAnimation <string>- Changes the animation played when not in a random/forced sequence.
SetPlaybackRate <float>- Sets the framerate at which animations are played.
TurnOff- Hides the prop through
EF_NODRAW. The Disable input does the exact same thing.
TurnOn- Shows the prop (by removing
EF_NODRAW). The Enable input does the exact same thing.
DisableCollision- Tells the prop to no longer be solid.
EnableCollision- Tells the prop to become solid again.
SetAnimationNoReset <string> (in all games since 
)- Force the prop to play an animation unless the prop is already playing the animation. The parameter should be the name of the animation.
FadeAndKill (in all games since 
)- Fade out then remove this prop.
