CSB Wallhack Blocker

Server-side ESP/wallhack protection: hides enemies from a client's packet unless there is a real line of sight.

CSB Wallhack Blocker defeats most wallhacks and ESP tools by never sending an enemy's position to a client that should not be able to see it. In FM_AddToFullPack the plugin evaluates, for every viewer/enemy pair, whether the enemy is inside the viewer's PVS and whether a traceline from the viewer's eyes reaches the enemy's centre or head. If there is no clear sight line, the enemy is dropped from that client's packet.

To avoid making legitimate play feel wrong, teammates are always visible and an enemy who has fired within a short grace window is always shown (their position is already given away by the shot).

Inspired by the classic AddToFullPack wall-blocker technique (Fysiks / OrangeBox). Independent GPL re-implementation.

Features

• PVS check plus dual traceline (body + head) per viewer.
• Fire-grace window keeps recently-shooting enemies visible.
• Teammates never hidden; only living enemy players are filtered.
• Everything is server-side; clients need no changes.

On very high-population servers the per-packet traceline has a CPU cost; tune csb_wh_firegrace to taste.
