Example

Lua (example)
local from = g_localActor:GetPos(); -- player position
    from.z = from.z + 1.6;  -- eye-height
    local dir = g_localActor:GetDirectionVector();
    dir = vecScale(dir, 50);  -- 50 units distance is max
    local skip = g_localActor.id; -- skip ourself
    local hitData = {};  
    local hits = Physics.RayWorldIntersection(from, dir, 1, ent_all, skip, nil, hitData);
 
    if (hits > 0) then
        CryAction.PersistantLine(from, hitData[1].pos, {1,0,1}, "myRay", 5);
    else
