Fading door crashing server

[zippy36jr]

So I am having issues with people just randomly joining and using fading door to crash my server. I am trying to make it where when a fading door is not active the prop is not collided with anything to try and prevent this from happening but I am looking through the COLLISION_GROUP Enumerations and I cant find one that makes the props not collide with each other and keep collisions with players, vehicles, etc...

Are you sure that's whats causing the crash? How did you approach this conclusion?

I watched the player do it. He spawned a prop, made it a fading door with start toggled on then he did it again about 30ish times maybe more then then when he toggled them them all the server crashed.

extract fading doors and edit lua\weapons\gmod_tool\stools\fading_door.lua
around 285 we have this

local function fadeDeactivate(self)
    self.fadeActive = false
    if self:GetMaterial() == self.fadeDoorMaterial and self.fadeMaterial then self:SetMaterial(self.fadeMaterial) end
    self:DrawShadow(true)
    if self.fadeCanDisableMotion then self:SetNotSolid(false) else self:SetCollisionGroup(COLLISION_GROUP_NONE) end
    local phys = self:GetPhysicsObject()
    if IsValid(phys) then
        phys:EnableMotion(self.fadeMoveable or false)--comment out this line so it doesn't unfreeze when unfading
        phys:Wake()
    end

    if self.fadeDoorCloseSound and Sounds and Sounds[self.fadeDoorCloseSound] then
        self:EmitSound(Sounds[self.fadeDoorCloseSound],350,100)
    end

    if self.FadeDoorSound then self.FadeDoorSound:Stop() end
    self.FadeDoorSound = nil

    if WireLib then
        Wire_TriggerOutput(self,  "FadeActive",  0)
    end
end
i suggest also adding this to your serverside code
local apm_tab={}
apm_tab.vars={}
apm_tab.vars.unfreeze_ent_delay=5
apm_tab.vars.unfreeze_ent_limit=10
hook.Add("OnPhysgunReload","apm_unfreeze_limiter",function(weapon,ply)
    if ply and IsValid(ply) and ply:IsPlayer() then
        local unfreeze_count=0

        if ply.APM_Next_unfreeze and ply.APM_Next_unfreeze>CurTime() then
            ply:PrintMessage(HUD_PRINTTALK,"please wait "..math.Round(ply.APM_Next_unfreeze-CurTime(),4).." seconds before trying to unfreeze props")
            return false
        end

        if apm_tab.vars.unfreeze_ent_delay and apm_tab.vars.unfreeze_ent_delay>0 then
            ply.APM_Next_unfreeze=CurTime()+apm_tab.vars.unfreeze_ent_delay
        end

        local APM_Ent=ply:GetEyeTrace().Entity
        if !APM_Ent or APM_Ent and !APM_Ent:IsValid() then return false end
        for k,Entity in pairs(constraint.GetAllConstrainedEntities(APM_Ent)) do
            local PhysObj=Entity:IsValid() and Entity:GetPhysicsObject()
            if PhysObj and PhysObj:IsValid() then
                PhysObj:Wake()
                if unfreeze_count < apm_tab.vars.unfreeze_ent_limit and !PhysObj:IsMotionEnabled() then
                    PhysObj:EnableMotion(true)
                    unfreeze_count=unfreeze_count+1
                end
            end
        end
        ply:SuppressHint( "PhysgunReload" )
        if unfreeze_count>0 then
            ply:SendLua( "GAMEMODE:UnfrozeObjects("..unfreeze_count..")" )
            return false--we have to return false to prevent the normal unfreezing from happening
        end
    end
end)

My anticrash might help.

It forces props to be in ghostmode when spawned or brought out of freeze mode.
