func_block_charge is a brush entity available in Left 4 Dead 2 Left 4 Dead 2. Chargers won't charge at players to which line of sight is blocked by this entity.

Warning.pngWarning:AABB is used for LOS obscuring, so clipping or rotating brushes does not change a brush's size as one expects.

Diagonal walls will always be ignored, ad it will take the furthest out corners of the diagonal walls and create one huge box around all of it. That box will be your brush entity.

If you need a large diagonal brush, you must create multiple small square entities aligned diagonally.
PlacementTip.gifPlacement Tip:See through fences, bridges where charger could try charging over a gap diagonally to you
Note.pngNote: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_charge
Warning.pngRisk 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.
