An entity that will cause a physics impact on another entity.
Name targetname <target_source> The name that other entities refer to this entity by.
Parent parentname <target_destination> The name of this entity's parent in the movement hierarchy. Entities with parents move with their parent.
Pitch Yaw Roll (Y Z X) angles <string> Direction to project the impact.
Magnitude magnitude <integer> Strength of the impact.
Distance distance <integer> How far to project the impact (if 0 uses a default value).
Point to Entity directionentityname <target_destination> If set, 'Distance' and Angle settings are ignored and the direction and distance to the target entity will be used.
spawnflags spawnflags <flags>
Kill Removes this entity from the world.
KillHierarchy Removes this entity and all its children from the world.
AddOutput <string> Adds an entity I/O connection to this entity. Format: <output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire (-1 == infinite)>. Very dangerous, use with care.
FireUser1 Causes this entity's OnUser1 output to be fired.
FireUser2 Causes this entity's OnUser2 output to be fired.
FireUser3 Causes this entity's OnUser3 output to be fired.
FireUser4 Causes this entity's OnUser4 output to be fired.
SetParent <string> Changes the entity's parent in the movement hierarchy.
SetParentAttachment <string> Change this entity to attach to a specific attachment point on its parent. Entities must be parented before being sent this input. The parameter passed in should be the name of the attachment.
ClearParent Removes this entity from the the movement hierarchy, leaving it free to move independently.
Impact Trigger the impact
OnUser1 Fired in response to FireUser1 input.
OnUser2 Fired in response to FireUser2 input.
OnUser3 Fired in response to FireUser3 input.
OnUser4 Fired in response to FireUser4 input.
