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

Question

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?

Answer 1

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.
