Garry'sMod Detecting if there's a wall between two players

I was wondering about how to detect if there's a wall between two players. Does a command to do it exists or any code snippet?

Solution

  • I'm sure there are multiple ways to achieve this.

    One is to use ents.FindAlongRay

    table ents.FindAlongRay( Vector start, Vector end, Vector mins = nil, Vector maxs = nil )

    Returns a table of all entities along the ray. The ray does not stop on collisions, meaning it will go through walls/entities.

    So if you know where both players are you can check wether the wall of interest is among the entities found along that ray between both players.
