Find empty spawn in room with full extensions.

[likeafox]

@ayrtep I would use room.energyCapacityAvailable to figure out how big you can build you're creeps, that way you don't have to count you're spawns/extensions.

Your spawn should always accept energy unless the RCL isn't high enough, do you know what error is coming back after you try a transfer?

If you read what I said above

room.energyCapacityAvailable returns null

so I just created a wrapper function to do it the long way until the 'bug?' gets fixed and room.energyCapacityAvailable returns the room's energyCapacityAvailable.

I checked the creep.transfer. The transfer is successful, but as far as I can tell no energy is transferred to the spawn. On the GUI the spawn's energy status stays around 50-80. Sometimes it goes up in ones, I think after I use the energy in the extensions to make a creep.

I am not sure if this is relevant, but it's happening on a steam private server.

You man have corrupted your api or your DB entries might be corrupt. Try these:

Game.spawns.Spawn1.store.getCapacity()
Game.spawns.Spawn1.store.getCapacity(RESOURCE_ENERGY)
Game.spawns.Spawn1.store.getCapacity('energy')
Game.spawns.Spawn1.energyCapacity

If this is on MMO it is very unlikely to be a DB error. If this is a private server, you may have found a problem when db upgraded to use the new Store schema.

Thanks, I'll try that the next time I reproduce.

I have reset my private server with a system.resetAllData(), and the new game does not have this problem.

It could easily be some form of corruption. My development cycle involves deleting and replacing the files in my .../127_0_0_1___21025/default directory every few minutes.

Spawn will stop generating energy if the combined energy of spawn + extensions in the room is 300 or above. Does that make any difference for you?

Ok, It happened again. The trigger this time might have been stopping the server for eight hours then restarting.

I tried

    console.log("Game.spawns.Spawn1.store.getCapacity()", Game.spawns.Spawn1.store.getCapacity());
    console.log("Game.spawns.Spawn1.store.getCapacity(RESOURCE_ENERGY)", Game.spawns.Spawn1.store.getCapacity(RESOURCE_ENERGY));
    console.log("Game.spawns.Spawn1.store.getCapacity('energy')", Game.spawns.Spawn1.store.getCapacity('energy'));
    console.log("Game.spawns.Spawn1.energyCapacity", Game.spawns.Spawn1.energyCapacity);

and got

Game.spawns.Spawn1.store.getCapacity() null
Game.spawns.Spawn1.store.getCapacity(RESOURCE_ENERGY) null
Game.spawns.Spawn1.store.getCapacity('energy') null
Game.spawns.Spawn1.energyCapacity 0

@ayrtep

Happened again. Looks like restarting a steam private server is very likely to set the spawn energy and hence room energy to null.

Having the same issue

[U-238]

If it happends on private server maybe this is same issue? https://screeps.com/forum/topic/2829/room-energycapacityavailable-returns-null-due-to-corrupted-spawn-store/2

[Qionglu735]

got the exact same issue here, after rebooting vm machine and restarting private server.

spawn.store and spawn.storeCapacityResource become an empty object.

if put energy into the spawn, spawn.store["energy"] will reappear, but spawn.storeCapacityResource still empty.

So this is the first time I have looked at the screeps engine, so I am probably missing stuff. However

https://github.com/screeps/engine/blob/master/src/game/game.js#L316

register.rooms[object.room].energyAvailable += object.store.energy;

register.rooms[object.room].energyCapacityAvailable += object.storeCapacityResource.energy;

We are += on something that could be null, in which case it would just turn null and stay that way forever!

https://github.com/screeps/engine/blob/master/src/game/store.js#L28

Here stuff in the store is set to "null" rather than "0" if the resource is missing.

I am just guessing, but I suspect there might be an issue here. The bit in game.js was only done 11 months ago. https://github.com/screeps/engine/commit/879b4ca215f1e0b7fd92c7b32c7e59bdc4722cfc#diff-47818c887f19982321abd70c2e741871 https://www.worktime.com/
