Need some help improving my CPU usage

@systemparadox I do the same, but I went one step further: I just run the spawning code once per room. No flags needed I just grab the first spawn off the availableSpawns list, which i build by getting all spawns in the room and filtering off ones that are currently spawning. If no spawns available, just quit the entire function early until next tick.

@systemparadox Fuck my life

I just coded my rooms so that they can only spawn 1 creep each tick to avoid duplicity on their names (name + Game.time), but just found a new issue. On each room's memory i have entries such as "desiredUpgraders = 1".

Then, on another module, i count creeps that belong to that room like that...

totalUpgraders = 0;
for (let i in Game.creeps){
    let thisCreep = Game.creeps[i];
    if(thisCreep.memory.role == 'upgrader'){
        totalUpgraders ++;
    }
    //And so on...
}
//And then...
if(totalUpgraders < desiredUpgraders){
    SpawnCreep('upgrader');
}

That was working perfectly so far, because there was only one spawn per room, but now that i have a room with controller level 7 and i have 2 spawns it will begin spawning that desired upgrader. Then, room.memory.isSpawning will be set to true for one tick to avoid duplicity on names, but the very next tick it will start spawning another upgrader on the other available spawn because the one being created doesn't exist yet so totalUpgraders < desiredUpgraders still returns true.

I've been thinking on how to face this situation for a while, but can't see how at this moment. How do u solve this?

Creeps exist while they are being spawned. That is, if you Spawn.spawnCreep([MOVE], 'scout1'), on the next tick Game.creeps.scout1 will exist, but with creep.spawning = true.

@systemparadox Oh! Then...their memory also exists? Rather than checking my creeps room by room, i could access them all and check instead their thisCreep.memory.myRoom ?

Thank you so much!!

I didn't really understand your answer, and i realize now. I just had to replace...

if(thisCreep.ticksToLive > ticksToDie){}

with

if(thisCreep.spawning || thisCreep.ticksToLive > ticksToDie){}

Thanks!

I keep improving my code trying to reduce CPU consumption, and this is where i am at this moment...(4 rooms CL7 and 5 rooms remote mining)

I tried to find information about stuff like Room.toJSON or Creep.toJSON but haven't found anything helpful. Can you please explain to me what is this?

Thanks in advance!

toJSON

I think you are save room and creep object to the memory, but I don't understand why so many count of call for this methods. Are you use JSON.stringify some where?

Because game objects are linked to each other?

Anyway, the best practices for Screeps is to avoid saving game objects to memory at all costs.

ObamaLlama

Game.getObjectById exists for a reason

@Flyasd1 @o4kapuk @ObamaLlama Yes...i save some objects in the memory. This is how i started doing it until i had an error, and then started saving their ids only (but older code remained the same because it works).

I'll rewrite as many code as i can to save only ids or any other important info. Thank you guys

P.S. I don't use JSON.stringify anywhere
