Biter Spawner Questions

[TheSAguy]

Hi,
I’d like to better understand some of the Biter Spawner variables:

Unknown to me:
max_spawn_shift = 0, - ?
max_richness_for_spawn_shift = 100, - ?
spawning_radius = 10, - Radius around spawner that an enemy can appear? Or zone that a player enters and it starts to spawn?
spawning_spacing = 3, - space between spawned units?

Thanks.

Not asking for a lot here....Just would like to know what these variables do.
Thanks.

Actually, it looks like it belongs to Modding help

Spawn shift determines how strong monsters are born from the spawner -- when the spawner is placed:

Code: Select all

spawnShift = prototype.maxSpawnShift * std::min(prototype.maxRichnessForSpawnShift, double(entityCreationParameters.richness)) / prototype.maxRichnessForSpawnShift;

And when spawning a monster:

Code: Select all

EntityID spawnedID = prototype.selectUnitToSpawn(this->spawnShift + this->getMap().getEvolutionFactor(), randomValue);

Here richness is the map generation parameter that allows us to use the same mechanism for placing resources and enemy bases and selectUnitToSpawn, basically determines which biter is born next time -- the higher the values, the stronger enemy.

Spawning radius is the radius around the spawner where new enemies are created.
Before spawning we also check if inside of this radius is not too crowded. spawning_spacing determines what "too crowded" means.

Thanks Bluecube for your response!!

Now, if someone could translate this for me

In Vanilla spawn shift would be 0 and maxRichnessForSpawnShift would have no effect, since you're multiplying that by 0
Using DyTech's Max Spawn Shift of 0.65, you'll get a value for spawnshift, so your spawned monster will have a chance of being bigger/stronger version in the table.

I guess the bottom line is that with a larger Max Spawn shift or a larger Max Richness you'll have a change of getting bigger monsters from the table when spawning a monster.
