func_block_charge is a brush entity available in 
Left 4 Dead 2. Chargers won't charge at players to which line of sight is blocked by this entity.
Warning:This entity applies its effect based on its AABB instead of its brush model. 
Placement Tip:See through fences, bridges where charger could try charging over a gap diagonally to you
Note:This entity in code is most likely just func_brush with classname keyvalue changed to func_block_charge. For example firing AddOutput "classname func_block_charge" on a func_brush makes it behave like func_block_chargeRisk of Confusion:This is not meant to block any sort of movement since it's not a solid brush that would block exclusively charging chargers.Image demonstration
