Env player blocker

Class hierarchy
CEnv_Blocker ↳CBaseEntity

Template:L4d series point It blocks any PC/NPC from entering of the specified type.
Examples of its use can be found in L4D1 Authoring Tools SDK content, such as the l4d_airport03_garage.vmf crescendo event.
It has also been used a lot in L4D2's _Commentary files in the maps folder. Those have been used to block areas where survivors could remain unharmed by infected. Or in the case of C4M2_Sugarmill_a, where Survivors are blocked from jumping onto a set of pipes to gain higher ground prematurely.

This entity is a very useful option for clips that must be toggled on and off during gameplay.
