Repair Rate calculation?

Repair rate is 2*BP*HP/cost, this decreases to 0.5*BP*HP/cost in combat, ie. when the unit getting repaired gets damaged by an enemy unit and for 10s after (BP contributors' combat status does not matter - they still add BP normally when themselves under fire). The total energy cost for 100% repair is half the unit's original cost, so the energy drain per second is equal to BP. Repair does not cost metal. Status effects (slow, EMP and disarm) affect repairers' repair speed, but not the repairee. Repair decloaks the repairers, but not the repairee. Units cannot use BP to repair themselves.

That means given equal BP, repair rate in HP/s among different units is proportional to their HP/cost and repair time is proportional to cost.

This is for repair through buildpower. There is also passive autorepair that happens automatically out of combat, and some units have passive combat self-repair on top of that. The default out of combat autorepair is 5 HP/s after 60 seconds out of combat. Stun through EMP disables this repair (and the out-of-combat timer does not count down while EMPed), but slow and disarm don't. Some units differ there and have it have it kick in faster and more potent:

quote: Banshee - 10 HP/s after 5s Glaive - 20 HP/s after 5s Scythe, most Chicken - 20 HP/s after 10s Kodachi - 10 HP/s after 1.66s (yes, that's almost instantly) Claw - 10 HP/s after 10s Commanders with Autorepair modules - 20 HP/s per Autorepair Module after 10s

Some units have permanent in-combat passive self-repair. Again, EMP stops it, slow and disarm don't.

quote: Commanders - 5 HP/s Strike Comms: 5 / 5 / 12.5 / 20 / 27.5 / 35 HP/s Ultimatum - 5 HP/s Athena - 20 HP/s Detriment - 30 HP/s Funnelweb - 20 HP/s

Amphs also have passive self-repair underwater, based on depth. This increases linearly with depth up to a per-unittype limit and is based on the seabed depth and not unit's current depth (ie. floaters benefit from it fully as if they weren't floating). Both EMP and Disarm disable this type of self-repair and Slow decreases it.

quote: Conch: up to 10 HP/s at 40 depth Duck: up to 5 HP/s at 40 depth Archer: up to 40 HP/s at 40 depth Buoy: up to 60 HP/s 30 depth Scallop: up to 10 HP/s at 40 depth Grizzly: up to 40 HP/s at 40 depth Angler: up to 20 HP/s at 40 depth Djinn: up to 30 HP/s at 40 depth

Finally, Gauss turret has 20 HP/s regeneration as long as it is closed.

All those repair types stack.

Are players supposed to know all that and take it into account when playing??

Of course, Connetable!

Nah, it should definitely be changed to be easier to remember. The first quote full of exceptions should all be the same hp/s (eg 10) after x seconds (eg 10). Same goes for permanent in-combet passive self-repair. Next, such special non-activatable abilities should be displayed as little icons in unit tooltips, in the command window, or some other place.

Like I said, all units not present there repair at 5 HP/s after 60s. The big group (starting with Tick) that has it start after 20s is simply due to not having the idletime defined and using engine default. Detriment's autorepair is actually out of combat repair with 0 timer. Vindicator and Claw are probably some legacy which would be ok to remove.

wait det has massive autorepair...

quote: (2*BP*HP)/cost OR 2*BP*(HP/cost)

those are exactly the same thing

quote: Amphs also have passive self-repair underwater, based on depth. This increases linearly with depth

So I can dig dig dig a big big hole and my ampbs will self-repair very very rapidly?

Detriment has no idle regen but massive regen otherwise?

You can stack combat regen and idle regen? If that is the case why don't autorepair modules have 5s idle regen stacked on top of the standard commander 5 hp/s?

:O
