Env player blocker

Class hierarchy
CEnv_Blocker ↳CBaseEntity

env_player_blocker is a point entity available in Left 4 Dead series. It blocks any Survivor and Special Infected from entering of the specified type, very similar to clip brushes, but in point entity form.

Examples of its use can be found in L4D1 Authoring Tools SDK content, such as the l4d_airport03_garage.vmf Crescendo Event.
It has been added to maps using Commentary System files a lot. Simply because they work like clip brushes, but they are point entities which can easily be added to fix "God Spots" or unintentional access to places without re-compiling the map.

Warning:Instead of being fully solid like a clip, players are able to enter its volume for a fraction of a second. Running against this entity, standing on top of it, or teleporting into it will cause the camera to jigger rapidly.
