GRW ER7 Gauss Rifle

The GRW-ER7 Railgun is a faithful recreation of the original RFW ER7 from Arma 2 DayZ Namalsk map. The ER7 is a Linear motor firearm that uses an electromagnetic force to fire a projectile at over 3500 m/s. Requires high capacity Railgun Batteries to fire.

Where the load comes from

Event hooks carry 99.8% of this mod's structural load. 0.001 ms/s in all.

99.8%Event hooks · 99.8%
6 hooks · 0.0012 ms/s

Event hooksrun when something happens: an inventory move, a hit, an action 6 hooks 0.0012 ms/s 99.8% AnimalBase.EEHitBy, AnimalBase.OnRPC, ItemBase.EEHitBy 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

11 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.

- ComponentEnergyManager.FindAndConsumeEnergy returns its own answer without consulting super.FindAndConsumeEnergy() — vanilla's conditions on this check, and those of every earlier-loaded mod, no longer apply.

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 22 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.
