Pokemon Swarm in BDSP

[defelper]

Is there a way to change the Pokemon swarm with PKHEX or cheat codes ?

I presume it’s a byte in event constants that change current spawn, but I’m not sure if anyone tried to document it.

I documented it here: https://github.com/kwsch/PKHeX/issues/3357

Constant 436 is a SWARM_SEED, 32-bit value generated once per day that decides swarm spawns. Formula is simple: SWARM_SEED % 28 = lookup_table_index

lookup_table_index ("+" means I tested this value manually, I didn't test every single one because they are clearly sorted based on location):
0+: Doduo (Route 201)
1+: Zigzagoon (Route 202)
2+: Cubone (Route 203)
3+: Nosepass (Route 206)
4: Phanpy (Route 207)
5: Dunsparce (Route 208)
6: Snubbull (Route 209)
7: Absol (Route 213)
8+: Spoink (Route 214)
9: Drowzee (Route 215)
10: Delibird (Route 216)
11: Swinub (Route 217)
12: Voltorb (Route 218)
13: Farfetch'd (Route 221)
14: Skitty (Route 222)
15: Natu (Route 224)
16+: Makuhita (Route 225)
17: Krabby (Route 226)
18+: Spinda (Route 227)
19: Beldum (Route 228)
20+: Pidgey (Route 229)
21: Corsola (Route 230)
22+: Surskit (Lake Verity)
23+: Lickitung (Lake Valor)
24+: Smoochum (Lake Acuity)
25+: Electrike (Valley Windworks)
26+: Slakoth (Eterna Forest)
27+: Magnemite (Fuego Ironworks)

You can edit that constant using "Research" tab in Event Flag Editor.

EDIT: My PR got merged, so if you build PKHeX from source you can edit named work value (SWARM_SEED) as well. That change is not included in 22.01.01 release.
