point_playermoveconstraint is a point entity available in all Source games. When given theTurnOninput, it constrains any players already-within a set radius around itself, then slowing them down when they get close to the edge of the radius.

Keyvalues

Name (targetname) <string>

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

Radius (radius) <float>

Radius to find players to constrain.

Bug:When this entity spawns radius squared is computed and that value is used to check whether constraint was broken on a player to stop its effect and fire OnConstraintBroken output. The issue is that changing radius using AddOutput doesn't update the radius squared variable and so the original radius is used to determine whether player broke the constraint  [todo tested in ?]

Constraint Width (width) <float>

Width of the constraint edge. This is the distance in which to start slowing players down as they approach the edge of the radius.

Speed Factor (speedfactor) <float>

Factor applied to the player's max speed as they approach the radius edge.

Inputs

TurnOn

Start constraining any players already within the radius.

TurnOff

Stop constraining any players previously constrained.

Outputs

OnConstraintBroken

Fired when a player breaks through the constraint. !caller = player
