Props not colliding with AI entity

[avito]

Can't seem how to make props collide with an AI entity I made.

shared.lua
ENT.Base = "base_ai"
ENT.Type = "ai"

ENT.PrintName = "Banker"
ENT.Spawnable = true
ENT.AutomaticFrameAdvance = true

function ENT:SetAutomaticFrameAdvance( bUsingAnim )
    self.AutomaticFrameAdvance = bUsingAnim
end

init.lua
function ENT:Initialize( )
    self:SetModel( "models/player/gman_high.mdl" )
    self:SetHullType(HULL_HUMAN)
    self:SetHullSizeNormal()
    self:SetNPCState(NPC_STATE_SCRIPT)
    self:SetSolid(SOLID_BBOX)
    self:CapabilitiesAdd(CAP_ANIMATEDFACE)
    self:CapabilitiesAdd(CAP_TURN_HEAD)
    self:DropToFloor()
    self:SetMaxYawSpeed(90)
self:SetUseType(SIMPLE_USE)
end
