## About the PR
<!-- What did you change in this PR? -->
EMP has been changed to target APC-powered-devices (most electrical
devices) as well as batteries to disable them. This means EMP can
interfere with autolathes, airlocks, atmos devices, substations and
SMES. The power draw of a single EMP grenade now cuts out a substation,
and the disabling effect prevents further recharge until it subsides.
EMP duration now also stacks, which creates a novel way to quietly black
out the station by attacking engineering SMES with 3 EMP grenades (6tc
EMP bundle) to black out the station for 3 minutes.
Edit, here's a detailed changelog of the PR,
Functionality:
- EMP disable has been generalised to kill and prevent further function
of every device/battery by interrupting recharge
- As a result of the above, some hard coded interactions have been
culled
- EMP disable duration now stacks with multiple EMP blasts
- EMP is now capable of draining from gravity generators
- The Charger system has been slightly reworked to facilitate
communication between batteries and chargers
Results:
- EMP grenade can disable basically every powered machine, most notably
doors
- EMP grenade has had its power drain upped to 2.7MW, which is slightly
more than a substation and 1/3 a SMES
- EMP grenade can now instantly kill substations
- EMP grenade can now instantly kill gravity generators
- 3 EMP grenades (6tc) can be used to kill SMES and disable recharge for
3 minutes with no evidence on the power monitor.
## Why / Balance
<!-- Why was it changed? Link any discussions or issues here. Please
discuss how this would affect game balance. -->
EMP at 2tc has a relatively low value-proposition when compared to C4
which is also 2tc. While EMP can probably black out one (or two if
you're lucky) APCs and can be used as a defensive option against
Stun/Lasers. C4 can be used to cut wires, substations, SMES, generators,
doors, reinforced walls, people and the list probably continues.
New EMP can be used to soft-bomb station power in an explosion that
isn't globally alarming (salv boom). Targeting the captain's office
directly may let you crowbar in and steal the locker but it leaves
ephemeral evidence in the form of everything electrical shimmering blue.
Opting to bomb substations blacks out a wider area, providing several
degrees of separation from your target. That is to say, new EMP grenade
favours map knowledge and rewards better stealth.
## Technical details
<!-- If this is a code change, summarize at high level how your new code
works. This makes it easier to review. -->
- `C.S/.../EmpSystem.cs` uses TryComp to turn on/off charging for
`C.S/Power/Components/PowerNetworkBatteryComponent`
- `C.S/Power/EntitySystems/PowerReceiverSystem.cs` listens to
`EmpPulseEvent` to turn off. Requests to turn back on are additionally
intercepted by `EmpSystem.cs` and cancelled.
- `C.S/.../GravityGeneratorSystem.cs` listens to `EmpPulseEvent` and
converts energy consumption to a normalised charge
- `C.S/Power/EntitySystems/ApcSystem.cs` no longer toggles its breaker,
but still listens to `EmpPulseEvent` for updating visuals.
- `C.S/Power/EntitySystems/ChargerSystem.cs` was refactored to add a
`ChargingComponent` flag to power cells instead of `ActiveCharger` on
itself. Battery and Charger communicate through this flag. Listens to
`EmpPulseEvent` for updating its state machine. New
`ChargerUpdateStatusEvent` allows batteries to update the charger's
status.
- `C.S/Power/EntitySystems/BatterySystem.cs` can now be disabled, and
checks for disabling before updating its charge. Raises
`ChargerUpdateStatusEvent` when hearing `EmpDisabledRemoved` to tell its
charger to start charging again.
- `C.S/Power/PowerWireAction.cs` checks for `EmpDisabledComponent`
before turning power back on.
- `C.S/SurveillanceCamera/Systems/SurveillanceCameraSystem.cs` and
`C.S/VendingMachines/VendingMachineSystem.cs` had redundant
`EmpPulseEvent` listeners culled.
- `Resources/Prototypes/Entities/Objects/Weapons/Throwable/grenades.yml`
buffed EMP grenade.
