CodeLock to ExpansionCodeLock Bridge

Makes other mods compatible with the DayZ Expansion BaseBuilding codelock (this mod was previously named MSP_ExpansionCodeLockCompat). This has to be loaded INSTEAD of the Code Lock mod by RoomService. It is recommended that you either wipe or use EntityReplacer to replace all instances of CodeLock with ExpansionCodeLock PRIOR to installing this mod.

Where the load comes from

Event hooks carry 100% of this mod's structural load. 0.007 ms/s in all.

100%Event hooks · 100%
6 hooks · 0.0072 ms/s

Event hooksrun when something happens: an inventory move, a hit, an action 6 hooks 0.0072 ms/s 100% BBP_BASE.EEItemAttached, Fence.EEItemAttached, ActionOpenFence.ActionCondition and 3 more

Counts how often each hook is dispatched and how many timers stay alive, not what the code inside does. Some rates are order-of-magnitude estimates; the methodology lists which.

Chain breaks, by consequence

2 overrides that skip super(), ranked by how much they can affect. On any server a break replaces vanilla's behaviour on that method and silences every earlier-loaded mod hooking it.

Where this mod runs often

Hooks on per-frame and high-rate surfaces, with what their bodies call. Body work, not the hook itself, is what costs frame time.

Other findings

super() only on some paths · 6 · warning
- Fence.CloseFence calls super.CloseFence() only on some paths — on the others the chain below this mod is dropped. CL2ECL_Bridge.pbo::Scripts\4_World\Fence.c:17
- Fence.PlaySoundSet returns true without consulting super.PlaySoundSet() on some paths — vanilla's conditions and every earlier-loaded mod's vetoes are bypassed there. CL2ECL_Bridge.pbo::Scripts\4_World\Fence.c:51
- Fence.RemoveAction calls super.RemoveAction() only on some paths — on the others the chain below this mod is dropped. CL2ECL_Bridge.pbo::Scripts\4_World\Fence.c:74
- ItemBase.AddAction calls super.AddAction() only on some paths — on the others the chain below this mod is dropped. CL2ECL_Bridge.pbo::Scripts\4_World\ItemBase.c:10
- ItemBase.RemoveAction calls super.RemoveAction() only on some paths — on the others the chain below this mod is dropped. CL2ECL_Bridge.pbo::Scripts\4_World\ItemBase.c:95
- ExpansionActionEnterCodeLock.ActionCondition vetoes early (returns false) on some paths and defers to super.ActionCondition() otherwise — composes safely with vanilla's and earlier mods' conditions. CL2ECL_Bridge.pbo::Scripts\4_World\ExpansionActionEnterCodeLock.c:3

What this report can tell you

Which vanilla methods the mod hooks, which of them drop the chain, how often each hook fires, and which risky calls sit inside hot hooks.

What it cannot

How long hook bodies take, network cost, or engine-side load. Measured across live fleets, most server lag comes from the engine and world state, not mod script chains — a light footprint does not clear a mod of lag, and a heavy one does not convict it. Methodology.

Everything else

All 34 overrides

Surface is the dispatch tier the rubric can price (— = unpriced); server is whether the override exists on a dedicated server; super() shows whether the vanilla chain is preserved on a server.
