SetParentAttachment <string>
Attach to a named attachment on the current parent. The entity will teleport so that the position of its root bone matches that of the attachment.
SetParentAttachmentMaintainOffset <string>
As above, but without teleporting. The entity retains its position relative to the attachment at the time of the input being received.
ClearParent
Removes this entity from its current movement hierarchy.

Shadow:

EnableShadow
DisableShadow
Control the entity's cheap render-to-texture shadow. Does not affect shadow mapping.

RenderFields:

Color <color255>
Set the rendercolor.
Alpha <byte>
Set the renderamt.

Outputs

Breakable:

OnBreak
Fired when this breakable breaks. (activator is the breaker)
OnTakeDamage
The breakable has taken damage.
OnHealthChanged <float>
The health of the breakable has changed. Passes the new value as a normalised percentage of max health.
OnPhysCannonDetach
Prop has started its ACT_PHYSCANNON_DETACH activity (caused by the gravity gun ripping it from a wall).
OnPhysCannonAnimatePreStarted
OnPhysCannonAnimatePullStarted
Prop has started its ACT_PHYSCANNON_ANIMATE_PRE or ACT_PHYSCANNON_ANIMATE activities. Both are caused by the player trying to grab the prop with the gravity gun; ANIMATE_PRE plays once, then ANIMATE starts looping.
OnPhysCannonAnimatePostStarted
Prop has started its ACT_PHYSCANNON_ANIMATE_POST activity (caused by the player letting the prop go from the gravity gun).
